This article discusses ethics in times of pandemic crisis (COVID-19) taking into consideration the sustainability paradigm. Two related ethical approaches are discussed and contrasted. On the one hand, the relational embodied ethics of the commons is discussed in the background of the pandemic of COVID-19. On the other hand, "lifeboat ethics" is interpreted in considering the pandemic situation. The main goal of the article is to compare the two ethical approaches as a way of dealing with our shared predicament in times of a pandemic, a state of exception, and based on that, to additionally derive conclusions about their application in further crises in the Anthropocene, whereby the primacy of sustainability is presumed.
This paper is structured into two parts, which are closely related: first, the analysis of the parlamentary and governmental measures against the covid-19 pandemic; and second, the future regulatory framework about freedom of movement and other rights in the European area, according to the new European pact on migration and asylum.
This paper analyzes some of the assumptions in which the varied use of technologies to confront the spread of the COVID-19 pandemic and protect people's health has impacted on the fundamental right to the protection of personal data; to do so, it starts from the premise that the use of these technologies cannot mean an affectation to the referred fundamental right, much less an indiscriminate treatment of such data without any minimum control whatsoever.
The study traces the development of compulsory vaccination in Germany against the background of political discussion and legislative activities, focusing on the area of tension between state health protection and the right to medical self-determination in the context of constitutional balancing. It is based on the assumption that the right to medical self-determination traditionally dominates state decisions in a democratic constitutional state and that the scope for decision-making is constantly being further contoured in the face of current challenges.
Impact of Covid-19 on company & insolvency law: An overview of Luxemburgish responses [new layout]
(2022)
Covid-19 outbreak had a huge impact on the economy worldwide as businesses had to close or cease their activities due to the lockdown regulations. The “luckiest” firms were able to operate but under restricted conditions. In order to avoid what certain authors called “bankruptcy epidemic” European countries took economic and fiscal measures to help companies compensate their financial losses. In addition to Government Grants, emergency legislations have been adopted with the aim to adapt insolvency and restructuring procedures to the sanitary situation and specific rules relating to company Law have also been implemented. This paper deals with the measures taken by the state of Luxembourg and gives a brief overview of the legal amendments
This paper evaluates the freedom of trade, occupation, and profession in South Africa from a Covid-19 pandemic context. It does that by focusing on the pertinent provisions and rights contained in the Constitution of the Republic of South Africa, 1996 (the Constitution) and relevant international and regional human rights instruments. It proceeds by discussing the interlinkage between (the freedom of trade, occupation, and profession and other pertinent fundamental) rights, limitation, enforcement, and interpretation of rights. This is followed by some final observations.
The following collection of manuscripts emerged from an international and interdisciplinary Virtual Exchange that took place during Covid-19 Pandemic in March/April 2021 organised by Prof. Milena Valeva and Prof. Kathrin Nitschmann. Covid 19 had -and still has in parts of the world- led to severe restrictions of fundamental liberties worldwide and thus enhanced debates on ethics and human rights. This debate appeared as a common denominator connecting citizens in countries all over the world. One of the concrete consequences for students was certainly the reduction of mobility, not only in the sense of not being allowed to visit the university but also in canceling planned international exchanges. In this context, the virtual exchange offered a chance not only to overcome the still lasting restrictions on mobility but also to exchange daily life experiences of students in Covid-times, merging into restrictions and/or violation of human rights in a legal and ethical dimension. Students from Peru, Israel and Bulgaria participated in the virtual exchange, which was supported by the International Teaching Award of Trier University of Applied Sciences, within the frame of of a summer school and had the opportunity to work synchronously and asynchronously in international and interdisciplinary teams on the topic COVID-19 - ETHICAL DILEMMAS AND HUMAN RIGHTS - EXPLORING INTERNATIONAL DIMENSIONS. Colleagues from Cape Town, Peru, Spain and Israel supported the event by their professional presentations. This special issue and at the same time first issue of the JOURNAL OF INTERNATIONAL AND DIGITAL COMMUNICATION: SUSTAINABILITY PERSPECTIVES is a collection of the manuscripts of the speakers, which at the same time reflects the diversity of the topics discussed and the international perspectives. Since this is a compilation of manuscripts, the authors were responsible for the scientific formulation of the texts.

Spinning ethical plates in times of pandemic and sustainability
[AI generated:] This article explores the cultural dependencies and symbolic nature of the Rights of Nature (RoN) within the context of the European Union (EU). It argues that the successful implementation of RoN in regions like New Zealand and Ecuador is deeply rooted in indigenous cultural perspectives, which contrast sharply with the anthropocentric legal frameworks prevalent in Western industrialized nations. The article highlights how the recognition of non-human entities as legal subjects in these countries is often a socio-political strategy rather than a genuine shift towards ecocentrism. The case of illegal gold mining in Ecuador exemplifies the ongoing dominance of anthropocentric perspectives, where economic interests frequently undermine environmental protections.
In contrast, the EU's approach to environmental justice is shaped by a lack of indigenous populations and the complexities of transposing EU law into national legislation. The EU primarily focuses on ecosystem services, emphasizing the necessity of environmental protection for human survival rather than granting rights to nature. This anthropocentric viewpoint is further reflected in societal attitudes towards environmental policies, where fears of economic disadvantage and social conflict hinder acceptance of transformative measures.
The article concludes that the global community is at a historic crossroads regarding ecological transformation, emphasizing the need for culturally sensitive approaches to avoid social resistance. In cultures where the protection of natural entities aligns with spiritual beliefs, RoN could be beneficial if implemented meaningfully. However, in EU countries where spirituality is diminishing and indigenous populations are scarce, adopting RoN may risk alienating the public and exacerbating political divisions. Therefore, enhancing existing environmental legislation is crucial to foster trust in its effectiveness and fairness, ensuring that vulnerable populations are not disproportionately affected.
Following arguments about feasibility of implementing and application of the Rights of Nature, this article is based on the exposition of elements of an economic nature in opposition to the (confirming) proclaimed position, adding a new point of view in relation to the different perspectives.
Therefore, the perspectives proposed here will be divided into three argumentative nuclei: the inability to maintain the actual environmental programs as a competitive economy, custom of all these projects to the members of the European Union and the energy crisis, linked to the failure to agree on new plans for energy supplies across.
The purpose of this work is to critically examine and reflect on the feasibility of granting legal rights to nature within the context of the European social and legal reality. We aim to address the following question: Should we grant legal rights to nature?
This is not merely a legal debate; rather, it extends to our fundamental understanding of the relationship between humanity and the environment. Some argue that we are at a turning point where granting rights to nature is the only way to protect our planet and ensure an environment suitable for future generations. Others, however, warn of the risks of creating a "legal chaos," considering the economic implications that such a radical shift might entail.
It's necessary to recognize nature rights in the European Union in order to guarantee an effective protection of natural entities and the common good. According to the International Union for Conservation of Nature (IUCN), at least 1,677 species out of 15,060 European species assessed are threatened with extinction (European Parliament, 2020). Currently, there are many dangers to ecosystems and biodiversity in Europe, such as climate change, urbanization and leisure activities, the pollution of air, water and soil as a consequence from agriculture, illegal killing and hunting, invasive species, and forestry activities (European Environment Agency, 2020).
In attention to these issues, we – as a society – need to find an effective way to protect nature. This essay will demonstrate how the recognition of the rights of nature is a valuable tool for achieving effective protection of ecosystems in European countries.
Conclusion: Perhaps a new Social Contract needs to be understood so that humans can operate more harmoniously with nature as well as with mankind. As long as the lens of life is only viewed through the interests that humans hold, the Rights of Nature cannot be actualized. This would cause chaos as climate change worsens, as less regard will be taken when more liberties are taken by harvesting the depleting resources. By taking action now, and giving nature personhood, humanity can have an intervention with itself and realize that taking advantage of entities that cannot speak for themselves, especially when it is extended to nature, is fundamentally wrong. As disputes over land and resources lessen as the lines of the Rights of Nature are followed, it will make the observance of the Social Contract easier to follow, therefore leading to a more pluralistic, peaceful society where the SDGs are closely adhered to, because nature will be granted rights at last.
The current global scenario is marked by conflicts, inequalities, and geopolitical tensions, which have created a growing sense of global insecurity, combined with the stagnation of progress towards the Sustainable Development Goals (SDGs) and the worsening of the climate emergency. This situation presents outcomes completely opposed to the promise of a better future, with greater prosperity and peace, which technological and scientific advances were supposed to bring to both people and the planet. These outcomes also demonstrate that we are wasting the opportunity to use technology, science, and global interconnectedness to achieve the aforementioned improvements (United Nations, 2024, Dec 22nd).
The global community needs to find real solutions capable of changing the course we are setting for the future of the planet and humanity.
In this regard, during the Summit of the Future, held in September 2024, world leaders made a series of commitments to sustainable development, financing for development, peace, international security, science, technology, innovation and digital cooperation, youth, future generations, and the transformation of global governance, establishing the “Pact for the Future” and its annexes: the “Global Digital Compact” and the “Declaration on Future Generations”, which aim to create international mechanisms to respond to current and future challenges and opportunities, striving for more security, justice, sustainability, and prosperity (United Nations, 2024, Sep).
In face to this scenario, environmental protection has become one of the greatest challenges for the global community. To address this, we need to mobilize all the means and resources available across various fields of knowledge. Among the tools available for environmental protection, ecological awareness and the transformative power of legal systems stand out, as well as the influences these instruments can have on each other in a mutual and continuous manner.
Increasingly frequent and severe extreme weather events are already affecting the European continent, posing serious threats to both the well-being of its citizens and its economies. Droughts are becoming more common and more intense, leading to reduced agricultural yields and higher rates of tree mortality (Buras et al., 2020). Coupled with rising temperatures, these conditions have resulted in an increase in wildfires, particularly in countries such as Greece and Portugal (European Forest Fire Information System, 2024). These fires not only devastate forests and biodiversity, but they also endanger public health and safety (European Climate and Health Observatory, 2024). Wildfires generally also release vast amounts of carbon into the atmosphere, which exacerbates climate change and creates a dangerous feedback loop (US Environmental Protection Agency, 2016).
While droughts and heatwaves are pressing issues, the opposite problem – excessive water – has be come a significant challenge as well, as flooding is the most frequent type of extreme weather event in Europe (CRED, 2021), with events like the 2021 floods in Germany and Belgium causing approximately 43 billion USD in damages. (Yale Climate Connections, 2022).
The impact of these events could increasingly threaten Europe’s economic interests by destabilizing key industries, such as agriculture, tourism or health care, and damaging billions worth of properties and infrastructure as climate change progresses. (Ciscar et al., 2011) A study indicated that Germany alone might face economic costs of up to 920 billion Euros by 2050 because of climate change. (GWS et al., 2022). But more importantly, these events endanger basic survival, as they can undermine food and water security and create public health crises. As Europe struggles to adapt, the increasing costs and risks highlight the urgent need for more comprehensive and innovative legal protection for the environment.
An innovative legal approach to better protect nature could be the concept of Rights of Nature (RoN). By granting natural entities “legal personhood” and therefore enabling them to have standing in court, it may become easier and more effective to protect the environment and climate from competing – often economic – interests.
The following chapters will delve into the idea of awarding legal rights to natural entities within the European context, drawing inspiration from the story of “Run Run,” a fox in Peru that was granted subjective rights.
Conclusion: Law is, and will ever be, a human (a societal) construct. As such, its instruments will always, tably, require human mediation. Given the seemly unstoppable acceleration of the ecological crisis, it is plausible that innovative proposals start to challenge the human-nature dualism enshrined in Law. Nevertheless, in doing so, some proposals risk fetishizing concepts, being merely performative without demonstrating real capacity to challenge the dualistic structure of the legal order. In fact, rights are a markedly humanistic juridical figure; therefore, transplanting them to non-human subjects generates a series of dogmatic problems, while reproducing the same individualistic worldview. The RoN are congenitally divisive and reductionist, forcing an unnatural enclosure of ecological systems in contained units and putting them in competition with other (human) rights. This is precisely what should be avoided if we take the present predicament seriously.
The focus of an authentically transformative legal theory should not be to extend the legal realm to colonize nature. On the contrary, the focus should be on integrating ecological dynamics into the legal order. Instead of giving rights to nature, we should be attributing humans stringent obligations towards nature. If the goal is to affect human behavior, which is the source of the immense devastation unraveling, then the reasonable way forward is to act on human behavior. It is the Law that must “ecologize”, not the other way around.
The debate surrounding the recognition of the Rights of Nature has gained global prominence, providing a legal and ethical approach that fundamentally reshapes societal perspectives on their connection with the natural world.
This paper explores the challenges of aligning the Rights of Nature with European societal values, highlighting how conventional Western legal systems and cultural attitudes have limited public support for Rights of Nature initiatives. The Rights of Nature (RoN) grants natural entities—such as rivers, forests, and ecosystems—inherent rights, akin to human rights, to exist and thrive independently of human use or exploitation. This perspective, deeply rooted in ecocentric values and often influenced by Indigenous worldviews, diverges sharply from the anthropocentric frameworks that have historically shaped European legal and environmental policies (Kauffman & Martin, 2017). Influential milestones, such as Ecuador’s 2008 Constitution and New Zealand’s 2017 Te Awa Tupua Act, have set significant precedents for RoN by recognizing ecosystems and natural entities as legal persons, affirming their intrinsic right to exist and regenerate without serving solely human interests (New Zealand Parliament, 2017; Constitution of Ecuador, 2008). However, these advances stand in contrast to Europe’s generally anthropocentric legal and cultural perspectives, which frame environmental protection as a means to safeguard human interests.
The following section provides an overview of the global RoN movement, underscoring its ecocentric and animistic roots, which emphasize nature’s intrinsic value and agency beyond human utility.
A closer look at Europe in section three reveals specific cultural, legal, and political barriers that hinder public support for RoN, including societal unfamiliarity with ecocentric ideals and an ongoing resistance to legal frameworks that prioritize nature's rights. This foundation helps illustrate why Rights of Nature remains an unfamiliar and often controversial concept in Europe, where environmental legislation predominantly supports human welfare and economic growth rather than advocating for nature's independent rights (de Lucia, 2015).
The challenges faced by public advocacy for Rights of Nature in Europe are examined in section four through the case of the Mar Menor Lagoon in southeastern Spain. This coastal lagoon, severely impacted by agricultural runoff and nutrient pollution, sparked public campaigns and regional support for its protection. Yet, despite these efforts, proposals to establish the lagoon’s legal personhood encountered substantial resistance. Opposition stemmed from concerns over economic interests, political inertia, and a general lack of societal awareness regarding RoN concepts (García Ruales, Hovden, Kopnina, Robertson & Schoukens, 2023; Guaita-García, Martínez-Fernández, Barrera-Causil, & Fitz, 2022).
In the fifth section, this paper advocates for a bottom-up, community-led approach to RoN in Europe, emphasizing the importance of decentralized solutions and public engagement as pathways to overcoming resistance. By fostering local awareness and encouraging grassroots movements, Europe may be better positioned to adopt Rights of Nature frameworks that reflect both ecological needs and societal values.
Through this analysis, the paper seeks to provide insights into the interplay between cultural ideologies, legal frameworks, and public perceptions that influence RoN's potential to reshape Europe’s approach to environmental protection.
The debate on whether nature should have its own rights has been carried out for decades, ever since the concept was introduced by Stone (1972). The intention has remained the same: protect natural entities within our anthropocentric world by using our own weapons. Although preserving the environment has become an even more urgent matter with the progressing loss in biodiversity, at the same time, legal instruments for its protection have evolved as well. This raises the question of the necessity of Rights of Nature. Were all those legal tools enforced in an effective and timely manner, would our environment be sufficiently protected from human interferences?
The current legal system, especially in European countries, is based on an anthropocentric view of the world. This grants natural entities protection only in their relation and worth to humans. Acknowledging nature’s inherent value might be a new innovative idea within western societies. However, it is a concept that has been practiced by indigenous peoples for a long time. Their ecocentric worldview has been eradicated from international and national law by colonialists (Guzmán, 2019). By introducing Rights of Nature in Europe, this ecocentric approach would be included in a legal system that is still based in a society in which anthropocentric views are deeply rooted. Despite the growing awareness of human effects on nature and the necessity to protect the planet as well as prevent further climate change, granting natural entities intrinsic rights would require a paradigm shift not only in European law systems but also in western societies (Peppoloni, 2024).
Since rapid action is vital for preserving our environment, it is questionable whether enough time remains for such a fundamental transition. Using and enhancing existing tools within the current system might be more effective. Therefore, the following article will show legal instruments already in place. As they are partly still lacking in their execution, room for improvement will be demonstrated, which would finally enable them to together provide sufficient protection for European nature. Namely, these tools include the Precautionary Principle, Human Rights, Nature Conservation laws and the possibility of litigation on behalf of the environment. These assessments will be made from a European point of view. It should be noted that analysing legal tools within other parts of the world rooted in different cultures might lead to divergent results.
Conclusion: In short, individuals play an essential role in monitoring the way in which State regulations are put into practice in relation to the protection of nature and, although civil society has proposed the recognition of RoNs, it cannot lose sight of the fact that the ideal and most effective mechanism to achieve this is through ex ante and ex post protection by the States and their respective Public Administration, for which a greater development of Administrative Law and the rate of compliance of its entities is required, which is directly related to the political will of the authorities, against which action can be taken. Finally, opting for the judicial route as the only mechanism for the protection of nature is insufficient; however, if this is used in conjunction with the demand to the Public Administration indicated in the previous point, better results can be obtained. For this, instead of creating new judicial processes or subjects of rights, it is recommended to use legal figures that already have a doctrinal and legal development that allow achieving the same objectives as quickly as possible in time, such as the jurisdictional protection of diffuse interests.
[AI generated:] This paper examines the development of arguments in favor of recognizing the rights of nature, particularly in the context of recent global social demonstrations supporting this paradigm shift. Despite the initial advantages associated with adopting this position, various theoretical and practical obstacles emerged during the argument compilation process. To ensure a clear and convincing argumentation, the position was divided into four key points. First, the legal possibility of this recognition is discussed from various philosophical theories. Next, the central role of NGOs and other environmental groups is highlighted. The third argument considers the practical perspective of judicial representation and general principles of law. Finally, an economic argument is presented that brings together the main concerns of many states in support of this paradigm shift. The arguments were developed with consideration of the key criticisms from the opposition, aiming not only to counter these questions but primarily to strengthen the position.
As global environmental challenges intensify, the concept of granting rights to nature has gained attention not only as an ethical imperative, but as an economically viable solution. In economic terms, the ecosystem services provided by protected areas are worth several hundred billion dollars a year (McNeely, 2020). Recognizing nature's rights – particularly for critical natural resources such as rivers and other water ecosystems – may create the foundation for sustainable economic growth, resilience, and long-term prosperity. In Europe, the argument for legal rights for nature could find support in factors such as improved resource management, reduction of environmental degradation costs (Darpö, 2021), stimulation of green industries (European Economic and Social Committee et al., 2020), and alignment with the European Union’s commitment to environmental sustainability (European Economic and Social Committee et al., 2020), which will be elaborated in this paper.
During the last decades, several actions have been carried out to try to reduce and even stop the repercussions of climate change, such as the creation of politics, laws, treaties and diverse mechanisms of action to ensure the care and protection of nature, however, such measures have not been enough to reduce the diverse types of impacts that the planetary ecosystem suffers.
Throughout this section, the integration of the ecocentric vision in the Law will be developed, with the main objective of recognizing the inherent rights of nature in Europe. This will be achieved through the use of existing legal and juridical figures, with special emphasis on Latin American latitudes, with the purpose of incorporating this modern advance of law in the European normative framework.
Granting Rights to Naturals Objects: The Future of Environmental Protection or Cultural Mismatch?
(2025)
Conclusion: To conclude, there is no doubt that humanity is currently facing a (man-made) climate crisis. Ecosystems are under increasing pressure and are changing rapidly (IPCC, 2023). Europe has a very extensive network of environmental laws and regulations that attempt to counteract climate change. However, it can be observed that these are not sufficient to solve today's environmental problems. Europeans show a high level of environmental awareness and dissatisfaction with current environmental policy. The insufficiency of environmental policies coupled with high environmental awareness in Europe is calling for a new approach to environmental protection.
The answer may lie in civic society: This article has demonstrated that Europe has a stable culture of committed citizens who fulfil their democratic responsibilities. Citizen movements have started to take inspiration from the Latin American examples and mobilize around granting rights to nature. The Rights of Nature initiatives that have emerged in Europe and the case of Mar Menor show that the concept of the rights of nature also fits into our European context and receives support. These actors already have influence as norm entrepreneurs: The study from Ireland shows that transnational networks such as The Community Environmental Legal Defense Fund are important norm champions for greater diffusion and effectiveness. The overarching goal is effective environmental protection, and from the above arguments it can be concluded that European civil society is dynamic, flexible and motivated to take the next step with more room for action to achieve direct environmental justice.
This chapter illustrates the interconnections between indigenous peoples’ rights, human rights, and environmental protection, highlighting their potential to reinforce each other within the context of the RoN. Through the case study of the Te Awa Tupua (Whanganui River Claims Settlement) Act 2017, the discussion examines the implementation of RoN in Aotearoa, New Zealand, its alignment with Māori legal and spiritual traditions, and the broader implications for the country’s environmental policy, justice frameworks, and decolonization efforts.
With a focus on the historical-political impact on the protection of the ecosystem, Prof. Dr. Nitschmann referring to Hsiao (2012) began with the Whanganui River case and used this example to show how law can be successfully used as an instrument for status quo conservation over centuries in favour of economic interests in an anthropocentric system, questioning during her reflections if a Rights of Nature concept is THE solution to actual environmental challenges.
This report summarizes the arguments presented by Prof. Dr. Milena Valeva during the second panel discussion, which was held in preparation for the planned simulated parliamentary debate of the students. The experts, Prof. Dr. Alexandra Aragão and Prof. Dr. Milena Valeva, shared their insights from the fields of political theory, environmental ethics, and human rights on the topic of Democracy, Rights of Nature (RoN) and social norm dynamics.
The basis for Valeva’s arguments was provided by the central claim of Aragão to emphasize the role of Environmental Pragmatism, which rejects the notion that effective environmental action requires a radical transformation of human value systems or adherence to one ultimate ethical principle. Instead, it promotes open-ended inquiry and adaptive democratic decision-making to navigate complex, real-world ecological challenges. The Paris Agreement, which employs a bottom-up and iterative approach, favoring flexible “pledge and review” systems, is celebrated as an embodiment of pragmatic climate diplomacy that fosters ambition through mutual accountability and continuous reassessment.
To further deliberate on this central claim, Valeva elaborated on the following two central questions, which refer to her paper titled “From Human Dignity and Human Rights to Sustainability within the Context of Democracy," published in Interdisciplinary Perspectives on the Interplay between Human Rights and Sustainability (Special Issue 2/2024).
* What are the limits of liberal democracy in dealing with sustainability and RoN?
* What is the potential of republican democracy for executing sustainability and RoN?
The theory of legal eco-innovation elucidates and streamlines the processes by which innovative legal actions contribute to driving the necessary transition towards sustainability.
The goal of the present study is to understand the need, the processes and the conditions for the legal acceptability of radical legal eco-innovation, taking RoN as an example.
In practice this means that the legal fiction of Rights of Nature should not be interpreted as an exoteric proposal of eccentric lawyers but rather as a wise and coherent legal eco-innovation initiative with a strong effectiveness potential in the European framework.
This issue presents the contributions of the participants of the international DAAD Blended Mobility Project “Giving nature its own rights - ethical and legal perspectives and the influence on the realization of selected SDGs” which took place in wintersemester 2025 at Trier University of Applied Science, Environmental Campus Birkenfeld (UCB) under the guidance of Prof. Valeva and Prof. Nitschmann and in collaboration with the Pontifical Catholic University of Peru and the University of Coimbra supported by Prof. Zegarra (PUCP) and Prof. Aragão (University of Coimbra).
The DAAD funded project used the concept of global education to strengthen students' democratic competences and social participation and integrates intercultural dimensions into teaching. Its content is in the context of Education for Sustainable Development (ESD) and is linked to the curricular content of the studies “Non-Profit Management”, “Environmental Economics and Environmental Law” and “Sustainable Business and Technology” at the UCB. As part of the project, students and professors from Peru and Portugal visited the UCB for a workshop week in the winter semester 2024/25.
Understanding and methods for interpreting the global agenda of the UN regarding the SDGs were developed within the framework of this ESD project. Students worked together in teams virtually and in person under the guidance of experts to critically evaluate existing anthropocentric systems and their imbalances and to develop strategies for overcoming the challenges of an ecocentered approach for the law and the system in general (institutions, companies, civil society).
Ahead of the mobility phase and the technical content on the SDGs and diverse Rights of Nature (RoN) perspectives, language and culture were key themes in the two virtual kick-off events. This approach made it possible to raise transcultural and ecological awareness and thus paves the way for interdisciplinary knowledge building in teams. The intense mobility week started off with creating international mixed teams which were the work groups for the whole week. Input was given by experts within moderated panel discussions referring to different perspectives such as ethics and society and law and culture.
The project focused on the Hunsrück-Hochwald National Park as a natural entity and local example, serving as a starting point for case studies from selected countries to provide a broad basis for interpreting SDGs 13, 14, 15, and 16. Students were introduced to the biodiversity of the park by an expert ranger and used it as an experience-oriented and stimulating place to experience the intelligence of nature.
To perform a well-prepared simulated parliament debate, four internationally composed teams were defined, whereby a particular real case study in the area of RoN was assigned to two teams. The preparation of the debate included the assignment of the debate’s roles to the team’s members and clarification of the functions of the given roles. The material preparation included research for and discussion about the relevant information, and the training of the argumentation scenarios. They prepared themselves or two possible scenarios: confirmation of the launching of RoN or rejection of it. The two case studies were defined as follows:
1. Grant legal rights to the Maranon River, demanding its protection as a rights-bearing entity, now!
2. Grant the status of a subject of rights to the little fox “Run Run”, now!
The debate concept allowed the students to transfer their theoretic knowledge in practical skills and thus contributes to the learning outcome of defending democratic values by contributing actively in democratic processes. With the idea to perpetuate the outcome of the project this issue publishes the student works related to the final debate and is completed by professors’ perspectives.

Vor dem Hintergrund der Beziehung zwischen gesellschaftlichen Herausforderungen und entsprechenden Beiträgen der Wissenschaft wurde am Beispiel des Themenbereichs Flucht und Migration untersucht, inwiefern die psychologische Forschung jeweils aktuelle gesellschaftliche und politische Fragestellungen aufgreift, ob sie eine evidenzbasierte Grundlage für diese Fragestellungen schafft und welchen Teildisziplinen der Psychologie die Forschungsthemen zugeordnet werden können. Dazu wurden mit Structural Topic Modeling die Abstracts von 4.073 Publikationen aus den deutschsprachigen Ländern, dokumentiert in der psychologischen Referenzdatenbank PSYNDEX und veröffentlicht zwischen 1980 und 2017, analysiert. Es konnten 19 Themen identifiziert werden. Den stärksten zunehmenden Trend zeigten Traumatisierung von Flüchtlingen, transkulturelle Psychotherapie sowie die rehabilitative Behandlung von Patienten mit Migrationshintergrund. Im Bereich der Situation von Ausländern und Gastarbeitern, der Kriminalität von Jugendlichen sowie der sozialen Integration und Akkulturation mit Bezug zur ehemaligen DDR zeigte sich die deutlichste Abnahme der Wahrscheinlichkeit. Das Thema Sprachentwicklung von Migrantenkindern wies die höchste Wahrscheinlichkeit auf, von empirischen Studien behandelt zu werden, das Thema Identitätsentwicklung die höchste Wahrscheinlichkeit von nicht-empirischen Beiträgen. Zusammenfassend wird konstatiert, dass sich im Bereich von Flucht und Migration wesentliche gesellschaftliche und politische Entwicklungen in der psychologischen Fachliteratur widerspiegeln. Hinsichtlich empirischer Beiträge zu den Themen zeigt sich ein gemischtes Bild. Die meisten Themen haben einen klinisch-psychologischen Schwerpunkt, wobei jedoch auch andere Disziplinen vertreten sind. Methodisch kann festgehalten werden, dass der Topic-Model-Ansatz eine hilfreiche Methode für szientometrische Untersuchungen mit großen Textmengen darstellt.
Reflection of mind on body
(2025)
Through jewelry, I aim to raise awareness of psychosomatic disorders conditions many silently endure. Jewelry, as a personal and tangible medium, interacts directly with the body, making it a powerful channel for expressing inner emotional wounds in a visible and intimate form. Inspired by psychologists such as Gabor Maté, Alice Miller, and Joyce McDougall who emphasize the deep connection between emotional experiences and the body my work seeks to spark honest and meaningful conversations about mental health and also drawing on the theories of Tilmann Habermas and Donald Winnicott, I explore how objects can embody vulnerability rooted in childhood. Jewelry, like a childhood doll, can act as a transitional object, worn close to the body, symbolizing connection, memory, and emotional support. Jewelry is more than physical adornment. It holds psychological and emotional weight, reflecting our inner states. Jewelry, in particular, shows how adornment can mirror mental and emotional realities. These objects are not only wearable but also speak on behalf of important issues such as mental health, making them both intimate and socially resonant. According to my research about psychosomatic problems, repressed emotions from childhood remain stored within the body. A child who feels hurt, ignored, or abandoned may find those realities too overwhelming to face, and in response, constructs a fantasy world to emotionally survive. To represent this imagined world, I create jewelry with playful, illusory, and childlike forms. However, their rough, organic textures made from bio-based materials hint at the hidden pain beneath the surface. These works expose how childhood coping mechanisms quietly persist into adulthood. To express the lingering impact of unresolved childhood experiences, I use incomplete forms and contrasting elements to evoke fragility. For me, incompleteness symbolizes wounds that never fully heal, continuing to shape our emotional lives. In some pieces, I incorporate heavy stones to represent the burden of unresolved psychological struggles and the weight of pressure that cannot easily be escaped. These works illustrate the emotional labor of confronting our past and emphasize the importance of selfawareness and healing. In my practice, I developed my bio-based materials with tactile textures sometimes harsh, raspy, and even unsettling that gradually evolved into a durable and waterproof form suitable for wearing on the body. These materials, along with irregular shapes and tension-filled contrasts in size, color, and form, visually express anxiety, inner conflict, and emotional pressure. Inspired by red AIDS ribbon, a small, simple symbol that raised global awareness, reduced stigma, and sparked compassion. It was powerful precisely because it had no author, no profit motive it was universal. Inspired by this concept, I created a series of simple brooches priced at 10 euros each, with the intention of producing many more. They are symbols of resilience and hope, designed to be accessible and to start conversations. Changing society is a big idea, but real change begins with individuals. If just one person is moved or transformed by wearing or encountering one of these pieces, then the work has succeeded. My goal is that each piece serves empathy, mindfulness, dialogue and creat awareness.
Control rooms play a crucial role in monitoring and managing safety-critical systems, such as power grids, emergency response, and transportation networks. As these systems become increasingly complex and generate more data, the role of human operators is evolving amid growing reliance on automation and autonomous decision-making. This paper explores the balance between leveraging automation for efficiency and preserving human intuition and ethical judgment, particularly in high-stakes scenarios. Through an analysis of control room trends, operator attitudes, and models of human-computer collaboration, this paper highlights the benefits and challenges of automation, including risks of deskilling, automation bias, and accountability. The paper advocates for a hybrid approach of collaborative autonomy, where humans and systems work in partnership to ensure transparency, trust, and adaptability.
Impact of Geometry on Chemical Analysis Exemplified for Photoelectron Spectroscopy of Black Silicon
(2025)
For smooth surfaces, chemical composition can be readily analyzed using various spectroscopic techniques, a prominent example is X-ray photoelectron spectroscopy (XPS), where the relative proportions of the elements are mainly determined by the intensity ratio of the element-specific photoelectrons. However, this analysis becomes more complex for nanorough surfaces like black silicon (b-Si) due to the geometry's steep slopes, which mimic local variations in emission angles. In this study, this effect is explicitly quantified through an integral geometric analysis using Minkowski tensors, correlating XPS chemical data with topographical information from Atomic Force Microscopy (AFM). This approach yields reliable estimates of layer thicknesses for nanorough surfaces. For b-Si, it is found that the oxide layer is ≈50%–80% thicker than the native oxide layer on a standard Si wafer. This study underscores the significant impact of nanoscale geometries on chemical property analysis.
The Active Radar Interferometer (AcRaIn) represents a novel approach in secondary radar technology, aimed at environments with high reflective clutter, such as pipes and tunnels. This study introduces a compact design minimizing peripheral components and leveraging commercial semiconductor technologies operating in the 24 GHz ISM band. A heterodyne principle was adopted to enhance unambiguity and phase coherence without requiring synchronization or separate communication channels. Experimental validation involved free-space and pipe measurements, demonstrating functionality over distances up to 150 m. The radar system effectively reduced interference and achieved high precision in both straight and bent pipe scenarios, with deviations below 1.25% compared to manual measurements. By processing signals at intermediate frequencies, advantages such as improved efficiency, isolation, and system flexibility were achieved. Notably, the integration of amplitude modulation suppressed passive clutter, enabling clearer signal differentiation. Key challenges identified include optimizing signal processing and addressing logarithmic signal attenuation for better precision. These findings underscore AcRaIn’s potential for pipeline monitoring and similar applications.
Physiotherapists’ knowledge, attitude and practice of clinical prediction rules in low-back pain
(2024)
Background and aim: Clinical prediction rules (CPRs) are mathematical tools that are intended to guide clinicians in clinical decision making or predict a future outcome, but they seem rather unknown, under-utilized, or avoided by clinicians. This study aimed to assess knowledge, attitude, and practice of CPRs in low-back pain (LBP) among physiotherapists.
Methods: A cross-sectional study involving 45 consenting specialist musculoskeletal physiotherapists from three public-funded teaching hospitals in Nigeria was carried out. An adapted validated questionnaire on facilitators and barriers to CPRs utilization, and a socio-demographic proforma were used to collect data. Descriptive and inferential statistics were employed to analyze data. Alpha level was set at p < 0.05.
Results: Respondents were mostly males (71.1%), married (64.4%) and first-degree holders (55.6%). Twenty-eight (62.2%) of the respondents had above-average knowledge of CPRs in LBP. Rates for positive attitude towards, and utilization of CPRs were 37.8% and 15.6%. Knowledge and attitude about CPRs in LBP were not significantly influenced by socio-demographic factors (p > 0.05). However, there was a significant association between the utilization of CPRs and years of experience (χ2 = 10.339 p = 0.016).
Conclusion: Most Nigerian physiotherapists had above-average knowledge, but a negative attitude and low utilization of CPRs in LBP. Clinicians’ years of clinical experience influence the usage of CPR. There is a need to incorporate training in CPRs into undergraduate and continuous professional development programmes.
This research delves into the emerging paradigm of biocultural systems, focusing on the intricate social-ecological dynamics which created and maintained an ancient farming system, the European wood-pastures. Innovatively conceptualizing wood-pastures as biocultural systems, this study employs a network approach to unravel the complex interactions between human activities and the natural particularities within these environments. By using field surveys and interviews conducted in Transylvania, Romania, this research reconstructs the traditional social-ecological drivers behind the preservation of ancient wood-pastures and their Nature’s Contributions to People (NCP). It identifies key variables and their centrality within the biocultural network, emphasizing that the rich natural values of wood-pastures are inextricably linked to management features. We employ RLQ and fourth corner analyses to investigate the interconnections among biophysical context, biocultural features (i.e. human made and natural features), and NCP, revealing significant correlations and gradients between the broad biophysical setting and the wood-pasture NCP. The findings underscore the importance of maintaining traditional management practices and stewardship to conserve the biodiversity and cultural heritage of wood-pastures. We contribute to a deeper comprehension of biocultural systems and offer insights for effective management and governance of traditional farming landscapes in Europe and beyond.
Widespread insect losses are a critical global problem. Mitigating this problem requires identifying the principal drivers across different taxa and determining which insects are covered by protected areas. However, doing so is hindered by missing information on most species owing to extremely high insect diversity and difficulties in morphological identification. To address this knowledge gap, we used one of the most comprehensive insect DNA metabarcoding data sets assembled (encompassing 31,846 flying insect species) in which data were collected from a network of 75 Malaise traps distributed across Germany. Collection sites encompass gradients of land cover, weather, and climate, along with differences in site protection status, which allowed us to gain broader insights into how insects respond to these factors. We examined changes in total insect biomass, species richness, temporal turnover, and shifts in the composition of taxa, key functional groups (pollinators, threatened species, and invasive species), and feeding traits. Lower insect biomass generally equated to lower richness of all insects and higher temporal turnover, suggesting that biomass loss translates to biodiversity loss and less stable communities. Spatial variability in insect biomass and composition was primarily driven by land cover, rather than weather or climate change. As vegetation and land-cover heterogeneity increased, insect biomass increased by 50% in 2019 and 56% in 2020 and total species richness by 58% and 33%, respectively. Similarly, areas with low-vegetation habitats exhibited the highest richness of key taxa, including pollinators and threatened species, and the widest variety of feeding traits. However, these habitats tended to be less protected despite their higher diversity. Our results highlight the value of heterogeneous low vegetation for promoting overall insect biomass and diversity and that better protection of insects requires improved protection and management of unforested areas, where many biodiversity hotspots and key taxa occur.
Penicillium sp. (IBWF 040-09) produces a protease inhibitor that can potentially be used against the main protease of human African trypanosomiasis. Since the target substance is formed intracellularly (under nutrient limitation), the fungal pellet is preferred compared to the free mycelia in bioreactor cultivation. The optimization of the production of protease inhibitor became the main focus of this study. The effects of the concentrations of spores, calcium chloride, and Pluronic F68 were investigated with regard to fungal growth, pellet morphology, and the production of protease inhibitor. The combination of adjusting the spore concentration and adding Pluronic F68 and calcium chloride increased the probability of achieving the desired morphology. This ensured better reproducibility of the production of the target substance by Penicillium sp. (IBWF 040-09) with the bioreactor system used. In addition, the protease inhibitor was tested in a resazurin assay and showed no noticeable cytotoxic effects on peripheral blood mononuclear cells isolated from whole blood cells.
(1) Objective: This study aims to lay a foundation for noncontact intensive care monitoring of premature babies.
(2) Methods: Arterial oxygen saturation and heart rate were measured using a monochrome camera and time-division multiplex controlled lighting at three different wavelengths (660 nm, 810 nm and 940 nm) on a piglet model.
(3) Results: Using this camera system and our newly designed algorithm for further analysis, the detection of a heartbeat and the calculation of oxygen saturation were evaluated. In motionless individuals, heartbeat and respiration were separated clearly during light breathing and with only minor intervention. In this case, the mean difference between noncontact and contact saturation measurements was 0.7% (RMSE = 3.8%, MAE = 2.93%).
(4) Conclusions: The new sensor was proven effective under ideal animal experimental conditions. The results allow a systematic improvement for the further development of contactless vital sign monitoring systems. The results presented here are a major step towards the development of an incubator with noncontact sensor systems for use in the neonatal intensive care unit.
The Duffing equation containing a cubic nonlinearity is probably the most popular example of a nonlinear oscillator. For its harmonically excited, slightly damped, and softening version, stationary large amplitude solutions at subcritical excitation frequencies are obtained when standard semi-analytical methods like Harmonic Balance or Perturbation Analysis are applied. These solutions have the shape of a nose in the amplitude-frequency diagram. In prior work, it has been observed that these solutions may contain large errors and that high ansatz orders may be necessary when applying the Harmonic Balance or other semi-analytical methods to make them converge. Some of these solutions are observed to be asymptotically stable, while in most cases, they are unstable. The current paper aims to give a descriptive explanation for this behavior of the nose solutions, which is mainly related to the exact solution of the free undamped vibrations. Based on this, approximations of the nose solutions are calculated with a procedure combining properties of Perturbation Analysis and Harmonic Balance. Therein, the exact solution of the free undamped vibrations is taken as the zeroth approximation, while higher-order solution parts are calculated by balancing the harmonics, and the phase shift of the zeroth approximation is calculated by a residuum minimization. This method just requires the solution of a system of linear algebraic equations, while systems of nonlinear algebraic equations have to be solved in the case of directly applying Harmonic Balance.
Epistemological Implications of a System — Theoretical Understanding for Sustainability Models
(2025)
In the sense of the Sustainable Development Goals (SDGs), global efforts to create a sustainable society will not be sufficiently successful under the current geopolitical and socio-economic trends. For this reason, recent sustainability research has increasingly focused on systemic coherence, the subject of cognition, and psychological and epistemological aspects. With regard to the sustainability discourse, this article proposes a perspective based on systems theory's findings in its enactivist interpretation. It understands this as a joint process of sense-making that must be actively maintained on an ongoing basis. Scientific knowledge and human experience are not described as mutually exclusive and informing spheres but as part of the world of experience actively spanned by the organism in its self-execution, which inherently involves ambiguities and complexity reductions that leave the subject and object undetermined. Such an understanding of systemic thinking should help to prevent the process of sustainable development itself from being called into question when some goals are inevitably missed.
The fiber volume fraction significantly influences the mechanical properties of fiber-reinforced composites. However, accurate measurements can be particularly challenging in natural-fiber-reinforced polymers. This study compared indirect methods using gravimetric and volumetric measurements with a U-Net-based direct method using micro-CT images for flax-fiber-reinforced polymers made via compression molding at 2.33–13.5 bar. A notable discrepancy was observed between the direct and indirect methods, with the latter yielding a fiber volume fraction approximately 25% lower than what could be determined optically. This difference arose from the matrix being absorbed by the fibers, resulting in a mixed region between dry fiber and pure matrix, further explained using a four-phase model. Our findings indicate that the volume fraction depended on the applied pressure. Specifically, we established a linear relationship between the fiber volume fraction and the pressure up to 9.4 bar, beyond which the fiber volume fraction plateaued. Furthermore, we examined the impact of void distribution in relation to pressure. At lower pressures, voids were distributed irregularly throughout the composite, whereas at higher pressures, the overall number of voids decreased, and they tended to concentrate primarily in the center.
The paper aims to review FinTechs' landscape in the context of their impact on countries' sustainable development reflected by SDG goals. The systematic literature review (SLR) applied the PRISMA methodology. It proved the worldwide systematically increasing scientific interest in surveying FinTechs and their contribution to SDGs' achievement. This trend has not yet been observed in Europe. Only a few papers directly refer to the relationship between FinTechs' and SDGs' achievement in European countries. Most of the research is qualitative. The topics range from conceptual framework to specific accomplishments of FinTech projects undertaken mainly by governments. They mostly refer to poverty alleviation through financial inclusion. The results of the systematic review of scientific research have shed light on the existing academic literature embracing both FinTech and SDGs issues, explored emerging trends in current research, and identified the main areas for further investigation.
Local disasters such as the Ahr Valley flood in Germany, the international backdrop of the Russo-Ukrainian War, or the global impact of the COVID-19 pandemic place high demands on the people and organisations that are involved in these situations and contexts to save lives, mitigate damage, provide comfort, or organise reconstruction. Novel technologies are constantly making their way into everyday life, such as artificial intelligence, big data, decentralised networks, internet of things, or virtual reality. Their adaptation, acceptance, usability, usefulness, and legal framework conditions for safety-critical systems must be researched and tested thoroughly. In this special issue, we investigate the use of computer-based solutions in areas and situations of direct relevance to people’s lives and well-being (Usable Safety), as well as contributions to user-oriented resilience concepts of sociotechnical systems concerning potential attacks (Usable Security) and data protection mechanisms (Usable Privacy).
Increasing evidence for insect biodiversity decline requires an identification of the causes but also an improved understanding of the limitations of the various underlying sampling methods. Trap comparisons foster comparability of larger-scale biodiversity studies by providing a deeper understanding of the variations in species abundances and trait compositions due to variations in trap characteristics. In our study, we compared five Malaise trap types on their catchability of butterfly species and noctuid moths and examined for the butterflies how this can be related to traits. We showed marked differences in species and trait occurrence in the samples of the different trap types which seemed to be influenced by roof colour (white, black) and trap shape (Townes trap: high, wide roof, Bartak trap: low, narrow roof). We found most butterfly species and most butterfly biomass in the white-roofed Townes trap. All butterfly traits were represented with most individuals in this trap. Compared with its black counterpart, it showed increased catches for pale butterflies and forest species. We found that dark-roofed traps captured fewer butterfly species and had a lower butterfly biomass. Townes traps captured more butterflies with larger wingspans, egg-laying locations higher above ground, and tree feeding behaviour compared to Bartak traps. Depending on the season and habitat, the differences in species capture may affect overall insect biomass.
With the commitment of more and more universities to decrease greenhouse gas emissions, standardizing the modeling is now becoming urgent. To date, published climate-relevant emissions can be based on completely different and incomparable accounting methods, as shown with results between 6 and 2696 t CO2e for the use phase of the same campus. This article aims to identify, compare, and evaluate the different modeling approaches behind this. For this purpose, this article proposes basic attributes of emissions modeling and reporting. Of the three established approaches to emissions accounting, sector logic (territorial carbon accounting) produces the lowest figures. Reporting in accordance with the greenhouse gas protocol, which has become established worldwide, can also shift the responsibility outside the institutional consumer. Life-cycle assessment, instead, essentially includes provision costs triggered by the consumer. The different modeling approaches also overlap with different coverage of emission sources, for which a standard set is being proposed. Such emissions modeling should finally lead to the determination of university-specific climate performances, i.e., the CO2e emissions per capita and per m2 of gross floor area. Infrastructure and procurement expenses must be recorded in addition and converted to an annual average.
Microbiologically Induced Calcium Carbonate Precipitation (MICP) is a technology for improving soil characteristics, especially strength, that has been gaining increasing interest in literature during the last few years. Although a lot of influencing factors on the result of MICP are known, particle size and shape of the particles remain poorly understood. While destructive measuring of compressive strength or calcium carbonate content are important for the characterization of samples these methods give no insight into the internal structures and pore networks of the samples. X-ray microcomputed tomography (micro-CT) is a technique that is used to characterize the internals of rocks and to a certain degree MICP-treated soils. However, the impact of filtering and image processing of micro-CT Data depending on the type of MICP sample is poorly described in the literature. In this study, single fractions of local quarry were treated with MICP through the ureolytic microorganism Sporosarcina pasteurii to investigate the influence of particle size distribution on calcium carbonate content, unconfined compressive strength and the reduction of water permeability. Additionally, micro-CT was conducted to obtain insights into the resulting pore system. The impact of the Gauss filter und Non-local means filter on the resulting images and data on the pore network are discussed. The results show that particle size has a significant impact on the result of all tested parameters of biosandstone with lower particle size leading to higher strength and generally higher calcium carbonate content. Micro-CT data showed that the technology is feasible to gain valuable insights into the internal structures of biosandstone but the resolution and signal-to-noise ratio remain challenging, especially for samples with particle sizes smaller than 125 µm.
Objectives: To investigate the feasibility and effects of a sensorimotor stabilization exercise intervention with and without behavioral treatment in nonspecific low back pain.
Design: A three-armed multicenter randomized controlled trial.
Setting: Five study sites across Germany (3 orthopedic university outpatient clinics, 1 university sports medicine department, and 1 clinical institution).
Participants: Six hundred and sixty-two volunteers (N=662) (59% females, age 39±13y) with low back pain.
Interventions: Sensorimotor training (SMT), sensorimotor training with behavioral therapy (SMT+BT), and usual care group (UCG; continuation of the already ongoing individual treatment regime). Intervention groups performed a 12-week (3wk center-based, 9wk home-based) program.
Main Outcome Measures: Adherence, dropout rates, adverse events, and intervention effects on pain intensity, disability, and trunk torque (gain scores, repeated measures analysis of variance, α-level<0.05).
Results: In total, 220 participants received SMT, 222 received SMT+BT, and 170 were analyzed as UCG. Dropout rates were 10% for SMT and SMT+BT at week 3, 31% and 30% at week 4, and 49% and 50% at week 12. Adherence rates above 80% were reached in both interventions; 134 adverse events occurred. Intervention effects compared to UCG were found for pain intensity (SMT, P=.011, effect size d=0.41), disability (SMT+BT, P=.020, d=0.41), and peak torque (SMT, P=.045, d=0.38; SMT+BT, P=.019, d=0.44), with overall small effect sizes.
Conclusions: Participants were highly adherent to the sensorimotor exercise, but showed increased dropout rates, particularly during home-based training. Both interventions proved to be feasible, and although only SMT showed an increased effect on pain intensity compared to UCG, the SMT+BT showed positive effects on disability. Both interventions led to increases in strength, indicative of a neuromuscular adaptation.
Introduction: The Evidence-Based Practice Confidence (EPIC) Scale measures health professionals’ self-efficacy associated with evidence-based practice activities. The scale has been cross-culturally translated into German together with physical therapists. To support its use in German-speaking countries, the measurement properties of the scale need to be determined. Therefore, the primary objective of this study was to assess the measurement properties of the German EPIC scale. In a preparatory step, we aimed to evaluate the comprehensibility of the scale among German-speaking occupational therapists, speech and language therapists, and nurses.
Methods: First, semi-structured cognitive interviews were used to evaluate the comprehensibility of the EPIC scale. Second, a longitudinal online survey with repeated measures (baseline and retest survey) was conducted. The target group included physical therapists, occupational therapists, speech and language therapists, and nurses from Germany, Austria, and Switzerland. Reliability, responsiveness, and validity were evaluated using internal consistency, test-retest reliability, standard error of measurement, known-groups method, exploratory factor analysis and the minimal detectable change, respectively.
Results: Comprehensibility of the German EPIC scale was confirmed by eleven health care professionals (four occupational therapists, two speech and language therapists, five nurses). The baseline and the retest surveys were completed by 708 and 222 participants, respectively. The measure demonstrated an internal consistency of .930, with an intraclass correlation coefficient (ICC) for test-retest reliability of .936 (95% CI: .917 to .951). The standard error of measurement was 4.92, and the minimal detectable change at the 95% confidence level was 6.02. All hypotheses in the known-groups method were confirmed, and construct validity was acceptable. Factor analysis revealed two main factors affecting the results of the scale.
Conclusion: The findings provide evidence that supports the use of the German EPIC scale among health professionals. For instance, it can be used to evaluate self-efficacy during EBP training.
Background: Psychoeducation positively influences the psychological components of chronic low back pain (CLBP) in conventional treatments. The digitalization of health care has led to the discussion of virtual reality (VR) interventions. However, CLBP treatments in VR have some limitations due to full immersion. In comparison, augmented reality (AR) supplements the real world with virtual elements involving one’s own body sensory perception and can combine conventional and VR approaches.
Objective: The aim of this study was to review the state of research on the treatment of CLBP through psychoeducation, including immersive technologies, and to formulate suggestions for psychoeducation in AR for CLBP.
Methods: A scoping review following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed in August 2024 by using Livivo ZB MED, PubMed, Web of Science, American Psychological Association PsycINFO (PsycArticle), and PsyArXiv Preprints databases. A qualitative content analysis of the included studies was conducted based on 4 deductively extracted categories.
Results: We included 12 studies published between 2019 and 2024 referring to conventional and VR-based psychoeducation for CLBP treatment, but no study referred to AR. In these studies, educational programs were combined with physiotherapy, encompassing content on pain biology, psychological education, coping strategies, and relaxation techniques. The key outcomes were pain intensity, kinesiophobia, pain catastrophizing, degree of disability, quality of life, well-being, self-efficacy, depression, attrition rate, and user experience. Passive, active, and gamified strategies were used to promote intrinsic motivation from a psychological point of view. Regarding user experience from a software development perspective, user friendliness, operational support, and application challenges were recommended.
Conclusions: For the development of a framework for an AR-based psychoeducational intervention for CLBP, the combination of theories of acceptance and use of technologies with insights from health psychological behavior change theories appears to be of great importance. An example of a theory-based design of a psychoeducation intervention in AR for CLBP is proposed and discussed.
Mitigating ongoing losses of insects and their key functions (e.g. pollination) requires tracking large-scale and long-term community changes. However, doing so has been hindered by the high diversity of insect species that requires prohibitively high investments of time, funding and taxonomic expertise when addressed with conventional tools. Here, we show that these concerns can be addressed through a comprehensive, scalable and cost-efficient DNA metabarcoding workflow. We use 1815 samples from 75 Malaise traps across Germany from 2019 and 2020 to demonstrate how metabarcoding can be incorporated into large-scale insect monitoring networks for less than 50 € per sample, including supplies, labour and maintenance. We validated the detected species using two publicly available databases (GBOL and GBIF) and the judgement of taxonomic experts. With an average of 1.4 M sequence reads per sample we uncovered 10,803 validated insect species, of which 83.9% were represented by a single Operational Taxonomic Unit (OTU). We estimated another 21,043 plausible species, which we argue either lack a reference barcode or are undescribed. The total of 31,846 species is similar to the number of insect species known for Germany (~35,500). Because Malaise traps capture only a subset of insects, our approach identified many species likely unknown from Germany or new to science. Our reproducible workflow (~80% OTU-similarity among years) provides a blueprint for large-scale biodiversity monitoring of insects and other biodiversity components in near real time.
This study explores consumer ethnocentrism (CET), distinguishing between Hard Ethnocentrism (HET) and Soft Ethnocentrism (SET), and their impact on Purchase Intentions (PIN), with gender as a moderating variable. Data from 372 Latin American native consumers were collected via an electronic survey, and a Structural Equation Model (SEM) and Multigroup Analysis were conducted to test the hypotheses. The findings reveal that HET does not significantly influence PIN, while SET positively impacts it. Additionally, gender differences in ethnocentrism levels were identified. This study is the first to examine consumers who stay in their native countries rather than emigrate, offering novel insights into international marketing strategies. By aligning with the Theory of Planned Behavior (TPB), marketers can foster positive perceptions, eliminate perceived barriers, and create impactful, gender-sensitive campaigns that resonate, particularly with female audiences.

Does the legal eradication of illicit crops in Colombia negatively impact the human rights of rural social groups living in the surrounding areas? Furthermore, can political and legal experiences of Germany contribute to this discussion? If you find these questions compelling, please keep reading. Through a set of papers, this section addresses the intricate relationship between human rights and the various policies that Colombian governments have implemented over the last few decades to eradicate illicit crops, in particular the coca plant.
This article aims to provide a concise yet comprehensive overview of the evolution of human rights and the Sustainable Development Goals (SDGs), tracing their historical development to the ongoing monitoring initiatives today. As we delve into the core of the discussion, a critical examination will be conducted to assess the alignment between the SDGs and human rights. The focal point will be a nuanced exploration of whether these two frameworks are in sync or if there are discernible deviations and potential conflicts of goals between them. To facilitate a more in-depth analysis, the SDGs will be systematically categorized into distinct clusters, enabling a clearer illustration of their compatibility or divergence from human rights principles. By breaking down the SDGs into specific thematic areas, we aim to shed light on both the areas where alignment is evident and those where disparities with human rights may exist. This comparative approach seeks to enhance our understanding of the interconnectedness and potential tensions between the SDGs and human rights. Moreover, the exploration will not only highlight the points of convergence but also delve into the complexities of ensuring a harmonious coexistence between these two vital frameworks. By examining the interplay of human rights principles with the diverse goals encapsulated within the SDGs, this article endeavors to contribute to a nuanced understanding of the broader implications for global development and social justice. In summary, this expanded article aspires to offer readers a more detailed exploration of the interrelationships between human rights and the Sustainable Development Goals, navigating through the clusters of SDGs to unveil areas of agreement and potential divergence. Through this analysis, we seek to foster a deeper appreciation for the complexities of aligning diverse global goals with fundamental principles of human dignity and equality.
The following article is intended to provide an initial overview about the relationship between the United Nations Sustainable Development Goals of 2015, as well as their Universal Human Rights of 1948, and catholic healthcare in the United States of America. The aim is to show why Catholicism in the US, despite its constitutional secularity, still has a major influence on ensuring adequate health care for all citizens and where religious influence conflicts with the basic principles of the SDGs and the UN's Universal Human Rights. This is done using the example of catholic hospitals and the role of Catholicism in the field of public health.
The goal of this contribution is to provide an overview of the conceptual connections between the constructs of human rights, sustainability, and democracy, emphasizing the historically significant role of human dignity. This overview serves as an overarching introduction to the students’ articles in Chapter One, which explore selected relationships between these concepts. One main assumption of this overview is that the concept of human dignity is central to the institution of human rights, and human rights are instrumental in ensuring human dignity. Another key assumption relates to democracy, which is viewed as the framework for shaping human dignity, human rights, and sustainability. This article first focuses on the relationship between sustainability and democracy. It then analyzes the links between human dignity and human rights, followed by a discussion on the connections between human dignity and sustainability, and between human rights and sustainability. Finally, it concludes with an examination of the triangle formed by human dignity, human rights, and sustainability within the context of democracy, emphasizing the crucial roles of human agency and the rights of nature. Clarifying these links is essential for future empirical research to develop specific practical recommendations for sustainability transformation, including human rights, within a democratic context.
Already more than 50 years ago, against the backdrop of the "earth science" findings of the time, voices could be heard in the legal literature expressing concern about the planet's carrying capacity, calling for consistent political rethinking and action and explicitly questioning consumer behavior and the ongoing pursuit of economic growth. The realization that the limits of environmental resources must be respected, and that growth must be shaped effectively within this framework has therefore been omnipresent not only since the "Our Common Future" report by the "World Commission on Environment and Development", or "Brundtland Commission" for short, in 1987 (United Nations General Assembly, 1987). Nevertheless, the current planetary status quo shows that the era of environmentally friendly economic development has by no means been effectively ushered in since then; on the contrary, implementation deficits or a lack of effectiveness of environmental protection measures against the excessive use of ecological resources are to be deplored. The demand for an ecological transformation of society is one of the most urgent on the political agenda and continues then as now, albeit partly with new terminology, at the level of jurisprudence: Currently, it is discussions about intertemporal freedom rights, nature's own rights and the greening of law that dominate the picture. However, the demand for ecologically oriented protection of fundamental rights is not new: the idea of protecting nature from excessive human behavior - also with a view to the generations of tomorrow and their chances of realizing a life in freedom in the future - is reflected not least in the precautionary principle, which is internationally recognized as a legal principle. Its ecological potential will be briefly explored below, culminating in an overview of constitutional tendencies towards an ecologically oriented protection of fundamental rights from a German perspective. This overview at the same time serves as an introduction for selected legal, ethical and social aspects of case studies in Latin America done by students in the context of a Human Rights interdisciplinary seminar in Wintersemester 2023/2024.
The achievement of sustainable development hinges on safeguarding the environment, preserving natural resources, and fostering economic growth that is intricately linked with responsible resource utilization. In simpler terms, sustainable development is contingent upon maintaining environmental sustainability. Conversely, Goal 16 of the 2030 Agenda for Sustainable Development emphasizes the need for global peace, justice, and robust institutions, aiming to uphold the rule of law and facilitate access to justice on a worldwide scale. Addressing environmental conflicts is an integral facet of environmental sustainability and a crucial component of ensuring access to justice. The escalating environmental challenges stemming from the relentless growth of the global population and the insufficient global adoption of renewable energy resources have significantly impacted the environment, leading to a corresponding surge in environmental conflicts. Given the considerable diversity in the judicial systems of nations worldwide and the often inefficacious nature of these systems, there arises a pressing need to reconsider and reconstruct effective alternative dispute resolution mechanisms, especially concerning their role in environmental conflicts. However, it is essential to acknowledge that Alternative Dispute Resolutions (ADR) come with their own set of barriers and drawbacks. This paper delves into a comprehensive examination and analysis of the role played by ADR methods in addressing environmental disputes. It assesses the effectiveness of these methods and conducts research to identify the factors that contribute to their success or failure.
The challenges and opportunities of liberal democracies in promoting international value systems
(2024)
In 1948, the United Nations proclaimed the Universal Declaration of Human Rights as a guideline for the protection of human rights. Not legally binding, the declaration represents an ideal that must be promoted by those who are committed to it. Among other amendments adopted since 1948, in 1998 the General Assembly passed a declaration seeking to strengthen the responsibility and right to protect human rights. "Stressing that all members of the international community shall fulfill, jointly and separately, their solemn obligation to promote and encourage respect for human rights and fundamental freedoms for all" (UN General Assembly, 1998,) this declaration is one of the central starting points of this paper. The Universal human rights formed the basis for many subsequent international treaties and agreements, one of the most recent being the 2030 Agenda with the SDGs. The legal situation of these agreements differs greatly in terms of their binding nature and enforceability. These issues will be examined in more detail in the following parts of this publication series. However, it should be noted here that successful implementation of the written goals requires voluntary debate and implementation. In today's multicultural, international context, some countries have significantly higher financial as well as social capital to fulfill these responsibilities. Based on the assumption that many of the existing liberal democracies fulfill these criteria of higher capacities, which will be discussed again in the course of the data analysis, this paper attempts to answer the question of what special responsibilities but also what opportunities are offered in this particular position.
To begin with, the current data situation will be examined in more detail. The focus here is on the international comparison of various reference values that are relevant to the issue at hand. First, we will take a brief look at the Human Rights Index (HRI), as processed by Our World in Data, what characteristics it has in international comparison and what questions and challenges can be derived from it. We will then take a look at the 2023 Sustainable Development Report (SDR). Here, again, we will try to recognize certain patterns in the international comparison. In a second step, we will link the progress of the individual countries with the respective income level, as already shown in the SDR. In addition, we include the Democracy Index, published by The Enonomist, in our data analysis. In the final step, we use all the data to build an overall picture that allows us to see the progress of global development in our area of interest and the associated challenges. In the following step, the results of this data analysis will be combined with further research findings and the question of the responsibility of liberal democracies in an international context. The challenges but also opportunities and possible benefits of promoting human rights and SDGs will be examined in more detail. Before concluding, we will try to generalize our findings to paint a picture of the inherent resilience of human rights and SDGs.
In recent years, a paradigm shift in environmental ethics has given rise to a groundbreaking concept granting legal rights to nature itself. As the global community grapples with escalating environmental challenges, select nations have taken unprecedented steps to acknowledge nature as a subject with inherent rights, transcending the conventional view of the environment as mere property. This term paper dives into the evolving landscape of environmental jurisprudence by exploring the inclusion of nature's rights in the constitutional frameworks of Ecuador, Bolivia, New Zealand, Colombia and India. Through a comparative analysis of these distinct cases, we unravel the diverse approaches these countries have adopted to recognize and protect the rights of nature, examining the legal, cultural, and ecological implications of this transformative concept. From the constitutional enshrinement of Pachamama's rights in Ecuador to the legal personification of the Whanganui River in New Zealand, this paper sheds light on the global movement for the rights of nature and its potential impact on environmental conservation and societal harmony.
This paper delves into the human right to an adequate standard of living, a fundamental principle articulated in the Universal Declaration of Human Rights (UDHR). The specific context under examination is the livelihood of artisanal Peruvian fishermen. The inquiry centers on understanding the prevailing standard of living for these individuals and exploring avenues for its optimization in harmony with both the environment and legal frameworks. In particular, this paper aims to identify and propose solutions for enhancing the living standards and working conditions of artisanal Peruvian fishermen, aligning with the principles of human rights, environmental sustainability, and legal compliance.
The paper, written by Maxi-Mercedes Jahn, is in particular about the use of glyphosate as the unique pesticide product provided for aerial aspersion. She discusses the forced eradication of more than 800 thousand hectares of coca in Colombia in 10 years, between 2012 and 2022, while discussing the reasons behind an increase in cultivation during this period. Circumstances may be dynamic, but the lack of state presence and for an effective land distribution have been some of the determinants to this problem. In 2019, drug trafficking revenues reached 31 billion of Colombian pesos, or 2.9 percent of the GDP. The business has remained healthy and thriving. Yet, the glyphosate supporters remain firm. Literature review reveals a lack of significant scientific debate on the efficacy of glyphosate as the best method for eradicating coca plantations. The use of glyphosate raises not only environmental concerns but also geopolitical issues, affecting conflict resolution and peacebuilding attempts. Coca cultivation is a viable business, it offers benefits such as more frequent harvests and reliable markets, enabling farmers to improve their income and living conditions in a relatively short term. Unlike other crops, coca does not require formal and legal export market. For example, while 14 kilos of Chontaduro (palm tree fruit) earn about 30 thousand Colombian pesos, a kilo of coca paste can cost 2 million pesos. This disparity highlights why substitution schemes are ineffective when drug revenues far exceed legal alternatives. The author’s insights into these often-overlooked factors contribute significantly to the discussion. She also addresses the Colombia-FARC peace agreement, which included comprehensive crop substitution policies, but progress has been minimal. It can even be said that increase in coca cultivation directly correlates with unmet agreement commitments. As well as other issues that are highlighted in the paper. The author notes that cartels have developed new methods to produce more cocaine with fewer plants, complicating government efforts. It also discusses the impact of technological advancements and the political complexities behind eradication policies. Back to the glyphosate issue, which it thorough in the paper, it mentioned that glyphosate negatively impacts that are usually not reported in mainstream media, like destroying soil organisms such as bacteria, fungi, and mycorrhizae, which are crucial for soil health and fertility. Farmers have reported adverse effects from glyphosate, including skin irritations that lead to permanent scars and vision problems. Reports also indicate that some farmers were mistakenly targeted during glyphosate applications, leading to the loss of their crops and livelihoods. This discussion underscores how the use of glyphosate, while intended for public health purposes, infringes on human rights and affects the lives of those in the impacted areas. Finally, the author makes a really interesting survey through the German Basic Law referring a few lessons for the Colombian case. The constitution orders the state to protect natural resources and life through prevention of harm, defense against threats, and risk assessment. The author highlights the balloon effect, linking deforestation, cattle ranching, coca production, violence, and displacement. More interestingly, she describes how glyphosate use exacerbates soil exhaustion and raises agricultural costs due to increased fertilizer and pesticide use. Additionally, she provides compelling information stating that spraying one hectare of coca can cost more than 50 thousand Colombian pesos, suggesting deeper issues, such as the influence of glyphosate producers in the overall transaction. The author concludes that broader goals of social justice, environmental stewardship, and sustainable rural development are needed. However, the discussion leaves unresolved questions about the environmental impact of glyphosate use. It emphasizes that the relationship between communities and their environment is complex, involving diverse, interdependent processes that go beyond the immediate effects of eradication efforts.
In the article, Cara-Maxine Heyd examines the complex relationship between USA war on drug policies and their impact on human rights for Colombia. It reflects on today’s relevance of the Universal Declaration of Human Rights (1948) as a framework for identifying and defining human rights. The article briefly addresses the use of glyphosate against coca plantations and the Colombia-U.S. Free Trade Agreement. It presents data on the historical growth of coca plantations and describes the affected social groups and regions, including peasant communities and deforested areas. She examines how various strategies to control coca cultivation, including aerial spraying with glyphosate, have impacted human rights, particularly the right to adequate living conditions. The use of glyphosate has affected over 100 thousand hectares, impacting numerous social groups, including landless peasants, indigenous peoples, and displaced communities by the internal conflict. The negative effects extend beyond health and livelihood, exacerbated by the illegality and social stigma associated with coca cultivation, which complicates institutional responses. Subsequently, the author explores how several human rights are impacted by eradication schemes related to coca cultivation. For the right to work, peasant growers, as the initial link in the cocaine value chain, face significant challenges. Government plans should focus on creating alternative job opportunities and supporting transitions to other products, including setting minimum wages and providing basic access to institutional benefits. Similarly, the right to food is compromised as new generations of peasants, born during the coca boom, have neglected traditional farming practices, leading to a loss of traditional agricultural practices and techniques agricultural. For the right to health and human dignity, glyphosate use exacerbates health issues and impacts non-coca crops, affecting food sovereignty and security. The author notes that glyphosate, classified as “possibly carcinogenic” by the World Health Organization, has been controversially used due to political rather than scientific evidence, which could trigger a humanitarian crisis. Lastly, the right to cultural life is affected by the marginalization of traditional coca use, which holds significant traditional and spiritual value in the Andean region. Traditional practices must be aligned to modern policies. This article also discusses the German constitutional right to a minimum subsistence level, which is consistent with human dignity. She explains the rationality behind this assimilation and provides context, also demonstrating how doctrine development and research conducted in different geographies can enhance the rights’ scope of protection. Therefore, coca peasants should be acknowledged as victims? The author response to this question from the decent standard of living perspective, offering an interesting approach to this communities’ situation. The author’s literature review and institutional sources detail the ambiguous legal status of coca globally and critique the reward-based system. She left several open windows to continue the investigation about where this situation is taking Colombia and the International community.
With her paper "Artisanal fisheries in circumstances with political framework and co-management" Dorothea Hensing discusses the high productivity of pelagic fish in the Humboldt Current Large Marine Ecosystem (HCLME) and how it is impacted by factors such as acidification and oxygen depletion due to global warming. This ecosystem, rich in marine life, faces significant challenges exacerbated by extreme weather events like El Niño and La Niña, profoundly impact the livelihoods of artisanal fishermen, creating economic instability. Despite these adversities, artisanal fisheries remain crucial contributors to Peru‘s GDP. However, their sustainability and financial stability are compromised by various factors, including the lack of institutional support and the prevalence of informal practices within the industry. Informality permeates aspects such as labor relations and vessel construction, consequently affecting workers' rights, their financial stability and rendering them vulnerable. Fishing communities, such as the one in Chorillos, are complex socio-ecological systems reliant on social capital, but they are susceptible to external influences. Political dimensions further complicate the scenario, necessitating the establishment of effective co-management mechanisms, artisanal fisheries' inclusion in decision-making processes, a comprehensive understanding of ecosystem threats, and policy reforms to address informality. The author demonstrates the importance of strengthening governance and decision-making processes to address institutional flaws and protect the marine ecosystems and livelihoods of artisanal fishermen in Peru.
When we want to understand why the laws of nature and nature itself are currently in such bad condition, we need to look at our way of seeing the world. When we want to stop the rapid deforestation, climate change, mass extinction, and other catastrophic impacts we have on our environment, we need to figure out at what time and why they started. There are fundamental differences between an anthropocentric worldview, where humans are above all other species, and an animist worldview, where humans are a part of nature. Due to people acting accordingly to their perception of the world, we need to understand why these perceptions differentiate so much and why people from the imperial core, respectively, the exploiting countries, think in a hierarchical pattern. Our disconnectedness from nature has reached a shocking extent. People living in big cities see nothing but concrete and cars; the plants they have in their homes are made out of plastic; and the only time they see animals is when they go to a zoo, where they are crammed in little enclosures and alienated from their natural habitat. Children growing up these days spend more time watching ads on TV or social media than they spend in nature. No wonder that many people know more brands than tree species, despite the fact that just one of those two keeps them alive. It is high time to question this development and to ask ourselves how we ended up here. Interestingly, there are still elements of a human-nature relationship visible in our modern capitalist society. Some people see their dog or cat as part of the family and talk to them; others care for plants as well as they do for their own children. And even in movies, a world is a portrait where the birds talk to the people and plants are alive. Therefore, the idea of nature being alive rather than just some material resource still prevails in our subconscious and in our fantasy to this day. The first part of this paper portrays our current perspective on nature and how it developed. From Plato’s Allegory of the Cave to the scientific revolution initiated by Francis Bacon and the dualism founded by Descartes, many theories influenced our perception of the world. The term Anthropocene is widespread, but it is rarely discussed or narrowed down when used. It will be discussed and elaborated on how the rise of capitalism is related to the accelerating exploitation of nature. The second part is about defining animism, the initial view of humans as a part of nature, which is still prevalent in indigenous culture. Cartesian dualism will be challenged, and other philosophical theories will be examined. The concept and theory of ecological feminism are going to be introduced, and the underlying analyses will be conducted in the context of animism. Our perception of nature will be debunked, and strong advocacy will be made for a more sustainable human-nature relationship.
Over forty years ago, physicist and deep ecologist Capra indicated: "Ecosystems sustain themselves in a dynamic balance based on cycles and fluctuations, which are nonlinear processes. Linear enterprises, such as indefinite economic and technological growth will necessarily interfere with the natural balance and, sooner or later, will cause severe damage. Ecological awareness, then, will arise only when we combine our rational knowledge with an intuition for the nonlinear nature of our environment. Such intuitive wisdom is characteristic of traditional, non-literate cultures, [...] in which life was organized around a highly refined awareness of environment." Since then, natural ecosystems are being pushed beyond their limits with human societies confronting unprecedented challenges like climate change, species extinctions and pollution. Various approaches like ecological restoration, conservation, renewable energies and car sequestration have been deployed to tackle the global ecological crisis. Yet, a crucial element remains largely overlooked: integrating local and traditional ecological knowledge as well as indigenous perspectives with modern western science to foster environmentally sustainable solutions. This student research paper explores how the concept of traditional ecological knowledge is defined in science, law and policy literatures and what contribution place-based communities such as the artisanal fishery of Chorrillos can serve for improving cooperative environmental and natural resources management. The method applied aims to evaluate existing literature, synthesizing ideas, and critically analyzing the status quo. Subsequently, the paper will provide recommendations for integrating ecological traditional knowledge in legal frameworks and practice through sound policy aimed at sustainable development.
Coca Cultivation in Colombian Economy – Considering the 2007 US-Colombian Free Trade Agreement
(2024)
According to the overarching theme "Should something happen somewhere else that we don't want to have here?", this research paper deals with the extended question "How does the 2007 free trade agreement between Colombia and the USA affect the situation in Colombia?". Focusing on the aspect of coca cultivation this paper is framed by the question of projecting the situation in Colombia onto the situation in Germany. Universal human rights are the unifying force between Colombia in Latin America and Germany in Central Europe. Through the United Nations Declaration, these rights have universal validity regardless of national or ethnic affiliation. These rights apply to all countries of the world, including Colombia. The situation of the population regarding the economic and ethical components is illuminated on the basis of coca cultivation. Starting with the topic of coca cultivation, the challenges and interests by groups of people involved are described. The Colombian economy is then examined in order to classify the importance of this topic. The topic of the "free market" is a very relevant one, particularly regarding the economic component and can be supported by free trade agreements. This means that the domestic economy is not only restricted to its own sales market without regulation but is also largely extended to other partner countries. In terms of market liberalization, this would also be relevant for coca distribution. Thus, opening to other markets at the direct level is an export opportunity, but also at the indirect level. Exports can also be expanded via third countries. However, national governments are also responsible for this process. Therefore, this paper also explains the role of Colombian politics in coca cultivation, as it has a significant role in the cultivation and trade of the coca plant as well as in external economic relations. Furthermore, the paper attempts to construct a possible solution to improve the living situation of the people in Colombia. The factors of the economy, politics, foreign policy and the relationships between the individual actors are considered in order to arrive at a solution that is as balanced as possible, taking into account the norms of human rights.
Rights for Nature in Germany
(2024)
In the last decades, the development of the rights of nature has become a significant issue in various parts of the world. This emerging approach views nature not only as a resource for human use, but as a value in its own right that must be protected and respected. Over the last years the discussion about a rights for nature have also increased in Germany. This paper takes a look at the current state of the debate on natural rights in Germany. The first part gives an overview about the current status of natural rights all over the world. The second part deals with the rights of nature in Germany and how these have developed in recent years, for example through the citizens' initiative in Bavaria, which addresses the rights of nature and makes them the subject of a referendum. The third part deals with the decision of the Federal Constitutional Court. This decision in March 2021 on the issue of climate protection marked a significant milestone in the context of the global climate crisis and finally the class action lawsuit.
The following collection of manuscripts emerged from an international and interdisciplinary Virtual Exchange that took place during Covid-19 Pandemic in March/April 2021 organised by Prof. Milena Valeva and Prof. Kathrin Nitschmann. Covid 19 had -and still has in parts of the world- led to severe restrictions of fundamental liberties worldwide and thus enhanced debates on ethics and human rights. This debate appeared as a common denominator connecting citizens in countries all over the world. One of the concrete consequences for students was certainly the reduction of mobility, not only in the sense of not being allowed to visit the university but also in canceling planned international exchanges. In this context, the virtual exchange offered a chance not only to overcome the still lasting restrictions on mobility but also to exchange daily life experiences of students in Covid-times, merging into restrictions and/or violation of human rights in a legal and ethical dimension. Students from Peru, Israel and Bulgaria participated in the virtual exchange, which was supported by the International Teaching Award of Trier University of Applied Sciences, within the frame of of a summer school and had the opportunity to work synchronously and asynchronously in international and interdisciplinary teams on the topic COVID-19 - ETHICAL DILEMMAS AND HUMAN RIGHTS - EXPLORING INTERNATIONAL DIMENSIONS. Colleagues from Cape Town, Peru, Spain and Israel supported the event by their professional presentations. This special issue and at the same time first issue of the JOURNAL OF INTERNATIONAL AND DIGITAL COMMUNICATION: SUSTAINABILITY PERSPECTIVES is a collection of the manuscripts of the speakers, which at the same time reflects the diversity of the topics discussed and the international perspectives. Since this is a compilation of manuscripts, the authors were responsible for the scientific formulation of the texts.

Additionally, Prof. Dr. Héctor Bombiella Medina, a lecturer of anthropology in the Department of World Languages and Cultures at Iowa State University, contributed to the virtual exchange and supervised case studies 3 and 4, bringing his extensive experience in this field and facilitating the international exchange. Within the elective module on Human Rights, students from the Bachelor's programs "Nonprofit and NGO Management" and "Environmental and Business Law," as well as the Master's program "Energy and Corporate Law," explored the interconnections between human rights and sustainability.
In an era marked by unprecedented environmental challenges and profound social transformations, the intersection of human rights and the rights of nature has emerged as a critical area of inquiry and debate. Today, as we face the dual crises of climate change and biodiversity loss, the traditional boundaries between human and environmental rights are increasingly blurred. This confluence demands a fresh, interdisciplinary approach to understanding and addressing the complex and interrelated issues at hand. Human rights, fundamental to the dignity and freedom of individuals, are deeply impacted by environmental degradation. Communities worldwide are experiencing firsthand the devastating effects of polluted air, contaminated water, and deforested landscapes, all of which undermine basic human rights to health, livelihood, and well-being. Conversely, recognizing the rights of nature — the intrinsic value of ecosystems and species — challenges us to reconsider our legal, ethical, and philosophical frameworks. It calls for a paradigm shift from a view to one that embraces the interconnectedness of all life forms. Engaging in robust discussions and research on these topics is essential in today's context. By exploring interdisciplinary perspectives, we can forge innovative solutions that honor both the rights of individuals and the integrity of nature. This special issue aims to contribute to this vital discourse, providing insights and fostering dialogue on how we can collectively navigate the complex landscape of human rights and environmental sustainability.
The first chapter „Human rights and SDGs in the context of democracy“ examines the significance of international human rights in today's context and links them to new value systems like sustainability. The second chapter, the case study „Rights of Nature“ explores the concept of granting legal rights to nature itself by comparing laws from various countries to show how it combats environmental exploitation. The third chapter, the case study „Traditional coca leaf consumption and drug trafficking in Colombia“ delves into the complex issues surrounding coca cultivation in Colombia, highlighting its economic, social, and political impacts. The fourth chapter, the case study „The artisanal fishing community of Chorrillos, Peru“ aims to provide theoretical insights and recommendations for improving the livelihoods of artisanal fishing communities in Peru, considering legal, ethical, and environmental perspectives as well as how economic liberalization, privatization, and deregulation affect the community's socio-economic conditions.

Deep learning-based image registration (DLIR) has been widely developed, but it remains challenging in perceiving small and large deformations. Besides, the effectiveness of the DLIR methods was also rarely validated on the downstream tasks. In the study, a multi-scale complexity-aware registration network (MSCAReg-Net) was proposed by devising a complexity-aware technique to facilitate DLIR under a single-resolution framework. Specifically, the complexity-aware technique devised a multi-scale complexity-aware module (MSCA-Module) to perceive deformations with distinct complexities, and employed a feature calibration module (FC-Module) and a feature aggregation module (FA-Module) to facilitate the MSCA-Module by generating more distinguishable deformation features. Experimental results demonstrated the superiority of the proposed MSCAReg-Net over the existing methods in terms of registration accuracy. Besides, other than the indices of Dice similarity coefficient (DSC) and percentage of voxels with non-positive Jacobian determinant (|J(phi)|=<0), a comprehensive evaluation of the registration performance was performed by applying this method on a downstream task of multi-atlas hippocampus segmentation (MAHS). Experimental results demonstrated that this method contributed to a better hippocampus segmentation over other DLIR methods, and a comparable segmentation performance with the leading SyN method. The comprehensive assessment including DSC, |J(phi)|=<0, and the downstream application on MAHS demonstrated the advances of this method.
A systemic framework of energy efficiency in schools: Experiences from six European countries
(2023)
Schools are complex physical and social institutions within national education systems. They account for significant energy consumption and like other buildings can demonstrate inefficient patterns of energy use. Poor energy performance of educational facilities is an intricate issue driven by complex causality of interconnected and dynamic factors. Addressing this issue requires a systemic approach, which is heretofore lacking. The aim of this research is to present and describe a systemic framework to facilitate energy reduction in schools across different European contexts. This transdisciplinary approach to sustainable energy use has been piloted in 13 post-primary schools located in six countries in northwest Europe. The research implements a series of planned activities and interventions, which help to unveil a systemic approach to improving energy efficiency in schools. The findings demonstrate how this approach, together with its ensuing methodologies and strategies, can contribute to reducing carbon emissions and improve knowledge and awareness around sustainable energy.
Small area estimation methods have become a widely used tool to provide accurate estimates for regional indicators such as poverty measures. Recent research has provided evidence that spatial modelling still can improve the precision of regional and local estimates. In this paper, we provide an intrinsic spatial autocorrelation model and prove the propriety of the posterior under a flat prior. Further, we show using the SAIPE poverty data that the gain in efficiency using a spatial model can be essentially important in the presence of a lack of strong auxiliary variables.
Model transformations are central to model-driven software development. Applications of model transformations include creating models, handling model co-evolution, model merging, and understanding model evolution. In the past, various (semi-)automatic approaches to derive model transformations from meta-models or from examples have been proposed. These approaches require time-consuming handcrafting or the recording of concrete examples, or they are unable to derive complex transformations. We propose a novel unsupervised approach, called Ockham, which is able to learn edit operations from model histories in model repositories. Ockham is based on the idea that meaningful domain-specific edit operations are the ones that compress the model differences. It employs frequent subgraph mining to discover frequent structures in model difference graphs. We evaluate our approach in two controlled experiments and one real-world case study of a large-scale industrial model-driven architecture project in the railway domain. We found that our approach is able to discover frequent edit operations that have actually been applied before. Furthermore, Ockham is able to extract edit operations that are meaningful—in the sense of explaining model differences through the edit operations they comprise—to practitioners in an industrial setting. We also discuss use cases (i.e., semantic lifting of model differences and change profiles) for the discovered edit operations in this industrial setting. We find that the edit operations discovered by Ockham can be used to better understand and simulate the evolution of models.
The Saarschleife geotope (SE-Germany) represents one of the most prominent geotopes of the SaarLorLux region and is known far beyond the borders of the Greater Region. Surprisingly, there is no visual representation of the relief history and genesis of this river meander, which is unique for Central Europe - as is common at places with comparable outstanding phenomena, such as e.g. the Rocher Saint-Michel d'Aiguilhe (France) or some national parks in the U.S. (e.g. Grand Canyon). The Saarschleife geotope therefore was choosen as a pilot object for the envisaged analysis of the landscape genesis but also regarding the 3D mapping and visualization. The visualisation presents the relief history and geological evolution of the last 300 million years in selected geological epochs, which are of fundamental importance for the understanding of today's geomorphological relief conditions, and is compiled into a summarized chronology.
Terrestrial cyanobacteria grow as phototrophic biofilms and offer a wide spectrum of interesting products. For cultivation of phototrophic biofilms different reactor concepts have been developed in the last years. One of the main influencing factors is the surface material and the adhesion strength of the chosen production strain. In this work a flow chamber was developed, in which, in combination with optical coherence tomography and computational fluid dynamics simulation, an easy analysis of adhesion forces between different biofilms and varied surface materials is possible. Hereby, differences between two cyanobacteria strains and two surface materials were shown. With longer cultivation time of biofilms adhesion increased in all experiments. Additionally, the content of extracellular polymeric substances was analyzed and its role in surface adhesion was evaluated. To test the comparability of obtained results from the flow chamber with other methods, analogous experiments were conducted with a rotational rheometer, which proved to be successful. Thus, with the presented flow chamber an easy to implement method for analysis of biofilm adhesion was developed, which can be used in future research for determination of suitable combinations of microorganisms with cultivation surfaces on lab scale in advance of larger processes.
Science on ecosystems and people to support the Kunming-Montreal Global Biodiversity Framework
(2023)
In December 2022, members of the Convention on Biological Diversity adopted the new Kunming-Montreal Global Biodiversity Framework (GBF) to guide international biodiversity conservation efforts until 2030 in order to be able to live ‘in harmony with nature’ by 2050. This framework addresses the implementation gap left after the Aichi Biodiversity Targets, which were the previous global instrument for mainstreaming biodiversity conservation between 2010 and 2020.
The aim of this editorial is to draw attention to the GBF targets that are most relevant to our readership, with two objectives: First, to suggest how Ecosystems and People may be a venue for emerging research insights in support of the GBF. Second, to highlight examples of recent research in Ecosystems and People that can contribute to enrich, or even challenge, the evidence and development of the GBF Targets.
Background: Physiotherapy education and practice have country-specific peculiarities which may limit globalization in health care. This study aimed to characterize physiotherapy practice and treatment preferences, educational qualifications, and research in Nigeria, with a view of providing vital information for transnational integration and collaboration.
Methods: A cross-sectional survey of 104 Nigerian physiotherapists was conducted. The Physical Therapy Practice Questionnaire and a self-developed proforma were used as survey tools.
Results: The mean age of respondents was 33.5 ± 9.4 years. About two-fifth of all respondents (39.4%) had an MSc and mostly practice as clinicians (51.0%) in teaching hospitals (34.6%). The respondents were mostly involved in general practice (50.0%), with a caseload of 1–10 patients per day (67.3%). Soft tissue mobilization (83%), proprioceptive neuromuscular facilitation (76%), breathing exercises (77%), and transcutaneous electrical neuromuscular stimulation (83%) were commonly used. Respondents were familiar databases and evidence-based resources (81.2%) and mostly utilize PubMed (73.3%). Regular case conferences with professional colleagues (47.6%) and treatment planning of between 11 and 30 min (40.6%) were common. Educators spend 1–3 h planning educational work (91.8%). Clinical decision-making is mostly based on professional experience, while journals are the primary resource for educational information.
Conclusion: Physiotherapy practice in Nigeria is degree based and requires registration board’s licensure. Practitioners deal with a high caseload and utilize a wide range of techniques and modalities and have tendencies to utilize personal experience and research in making clinical decisions. The parity in education and practice with advanced climes inadvertently gives physiotherapy practice in Nigeria a global purview.
1. Woody riparian vegetation (WRV) benefits benthic macroinvertebrates in running waters. However, while some functions are provided by WRV irrespective of surrounding and catchment land use, others are context-specific. In recent large-scale studies, effects of WRV on macroinvertebrates were therefore small compared to catchment land use, raising the question about the relevance of WRV for restoration.
2. Model-based recursive partitioning was used to identify context-dependent effects of WRV on the macroinvertebrates' ecological status in small (catchment area 10–100 km2) lowland (n = 361) and mountain (n = 748) streams. WRV cover was quantified from orthophotos along the near (500 m) and far (5000 m) upstream river network and used to predict the site's ecological status. Agricultural, urban and woodland cover at the local and catchment scales along with hydromorphology were considered as partitioning variables.
3. In rural agricultural landscapes, the effect of WRV on the ecological status was large, indicating that establishing near-upstream WRV can improve the ecological status by as much as two of the five classes according to the EU Water Framework Directive.
4. Even in urban landscapes, effects of far-upstream WRV were large if catchments had a moderate share of agricultural land use in addition. The beneficial effects of WRV were only limited in purely urban catchments or in a multiple stressor context.
5. Synthesis and applications. While woody riparian vegetation (WRV) can even improve the ecological status in urban settings, it is especially relevant for river management in rural agricultural catchments, where developing WRV potentially are effective measures to achieve good ecological status.
The objective of the German non-profit association NFDI (German short form for ”National Research Data Infrastructure”) is to make the data stock of the entire German science system accessible to the public. To do so, it should involve all stakeholders. However, currently the Universities of Applied Sciences (UAS) are underrepresented in the NFDI, and there is a danger of neglecting their needs. Therefore, we present the project ”Research Data Management at Universities of Applied Sciences in the State of Rhineland-Palatinate” (FDM@HAW.rlp), which is funded by the German Federal Ministry of Education and Research (BMBF) and financed within the Recovery and Resilience Facility of the European Union. In the project, seven public UAS in Rhineland-Palatinate and the Catholic University of Applied Sciences (CUAS) Mainz follow a common goal: They intend to establish an institutional RDM within a period of three years by building up competencies at the UAS, setting up services for researchers and finding solutions for a common technical infrastructure.
In 2020, a year of turbulence, seismic in scale and rapid in impact, luxury brands strengthen their relationship with art. While the world is still processing the effects of the last decades (digitalization, sustainability, diversity), luxury brands and art collaborations are used as a strategic tool in luxury brand management to create value. As the pandemic and broader social outrage exposed fault lines in society, even more luxury brands open flagship stores designed in collaboration with archistars (famous architects). Luxury brands establish foundations where art is exhibited and promoted. Culture funds become the new patrons of art. Limited art editions of iconic luxury products turn to revenue boosts. This research focuses on a case study of luxury brand and art collaborations. The ten most valuable luxury brands are used to analyze luxury brand and art collaborations as a leverage on brand equity and art(ist) equity. The bleeding of personal luxury good brands as well as contemporary visual arts are focused. The study identifies particularly positive effects deriving from art in the creation of equity value. The core issue discussed is whether contemporary art may represent a possible strategic tool for competing and differentiating in the global luxury industry up to 2030. The research investigates two main concepts that represents the theoretical framework: art and luxury. Literature research deductively links this case study with appropriate theories on brand equity and art(ist) equity. During this, a time horizon between 2019 and 2021 is chosen to address the latest insights in luxury brands and art collaborations. The topic is investigated explorative and qualitative with expert interviews. To tackle the research topic all-encompassing, the following groups of recognized stakeholders have been interviewed: (1) luxury brands, (2) artists, (3) art galleries, (4) trend and market researchers, (5) luxury customers and (6) city. Finally, managerial insights on the implementation of artistic collaborations are derived and suitable strategies for luxury brands who plan to be involved in such collaboration agreements are suggested. The sticking point in former academic research has always been concrete proof that luxury brands and art collaborations lead to an increase in equity beyond a short-term social media buzz or press coverage. This is the reason why this paper develops an S-O-R equity model to show the causality effects of such collaborations.
Die Umbenetzungsagglomeration bietet die Möglichkeit einer Trennung nach zwei Partikeleigenschaften. Hierbei wird nach den Benetzungseigenschaften des Feststoffs in Bezug zur Suspensions- und Bindeflüssigkeit getrennt und nach der Größe. Ziel dieser Arbeit ist, die Reinheit der entstehenden Graphitagglomerate in einer Mischung mit Quarzsand gravimetrisch zu bestimmen und diese mit den Benetzungseigenschaften zu korrelieren. Die Güte dieser Ergebnisse wird mit einer Mikroröntgentomographie (µ-CT) untersucht. Es konnte gezeigt werden, dass sich Quarzsand mit Paraffinöl nicht benetzen lässt und somit Reinheiten von 99,5 % bis 99,9 % erreicht werden, was das Ergebnis der µ-CT bestätigt. Einen Einfluss der Partikelgröße des Quarzsandes konnte im untersuchten Bereich nicht bestätigt werden.
Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable to biodiversity loss1. Mitigation measures, including wastewater treatment and hydromorphological restoration, have aimed to improve environmental quality and foster the recovery of freshwater biodiversity2. Here, using 1,816 time series of freshwater invertebrate communities collected across 22 European countries between 1968 and 2020, we quantified temporal trends in taxonomic and functional diversity and their responses to environmental pressures and gradients. We observed overall increases in taxon richness (0.73% per year), functional richness (2.4% per year) and abundance (1.17% per year). However, these increases primarily occurred before the 2010s, and have since plateaued. Freshwater communities downstream of dams, urban areas and cropland were less likely to experience recovery. Communities at sites with faster rates of warming had fewer gains in taxon richness, functional richness and abundance. Although biodiversity gains in the 1990s and 2000s probably reflect the effectiveness of water-quality improvements and restoration projects, the decelerating trajectory in the 2010s suggests that the current measures offer diminishing returns. Given new and persistent pressures on freshwater ecosystems, including emerging pollutants, climate change and the spread of invasive species, we call for additional mitigation to revive the recovery of freshwater biodiversity.
This research conducted a probabilistic life-cycle assessment (pLCA) into the greenhouse gas (GHG) emissions performance of nine combinations of truck size and powertrain technology for a recent past and a future (largely decarbonised) situation in Australia. This study finds that the relative and absolute life-cycle GHG emissions performance strongly depends on the vehicle class, powertrain and year of assessment. Life-cycle emission factor distributions vary substantially in their magnitude, range and shape. Diesel trucks had lower life-cycle GHG emissions in 2019 than electric trucks (battery, hydrogen fuel cell), mainly due to the high carbon-emission intensity of the Australian electricity grid (mainly coal) and hydrogen production (mainly through steam–methane reforming). The picture is, however, very different for a more decarbonised situation, where battery electric trucks, in particular, provide deep reductions (about 75–85%) in life-cycle GHG emissions. Fuel-cell electric (hydrogen) trucks also provide substantial reductions (about 50–70%), but not as deep as those for battery electric trucks. Moreover, hydrogen trucks exhibit the largest uncertainty in emissions performance, which reflects the uncertainty and general lack of information for this technology. They therefore carry an elevated risk of not achieving the expected emission reductions. Battery electric trucks show the smallest (absolute) uncertainty, which suggests that these trucks are expected to deliver the deepest and most robust emission reductions. Operational emissions (on-road driving and vehicle maintenance combined) dominate life-cycle emissions for all vehicle classes. Vehicle manufacturing and upstream emissions make a relatively small contribution to life-cycle emissions from diesel trucks (<5% each), but these are important aspects for electric trucks (5% to 30%).
This study aimed to investigate whether neurological patients presenting with a bias in line bisection show specific problems in bisecting a line into two equal parts or their line bisection bias rather reflects a special case of a deficit in proportional reasoning more generally. In the latter case, the bias should also be observed for segmentations into thirds or quarters. To address this question, six neglect patients with a line bisection bias were administered additional tasks involving horizontal lines (e.g., segmentation into thirds and quarters, number line estimation, etc.). Their performance was compared to five neglect patients without a line bisection bias, 10 patients with right hemispheric lesions without neglect, and 32 healthy controls. Most interestingly, results indicated that neglect patients with a line bisection bias also overestimated segments on the left of the line (e.g., one third, one quarter) when dissecting lines into parts smaller than halves. In contrast, such segmentation biases were more nuanced when the required line segmentation was framed as a number line estimation task with either fractions or whole numbers. Taken together, this suggests a generalization of line bisection bias towards a segmentation or proportional processing bias, which is congruent with attentional weighting accounts of line bisection/neglect. As such, patients with a line bisection bias do not seem to have specific problems bisecting a line, but seem to suffer from a more general deficit processing proportions.
The research program “Engineered Artificial Minerals (EnAM)” addresses the challenge of recycling valuable elements from battery waste streams. These elements, such as lithium (Li), often migrate in the slag phase, in some cases as crystals. EnAM crystals represent concentrated reservoirs of these elements, which can only be effectively recycled if they are extracted from the slag matrix and then separated. Selective wet agglomeration is a separation process based on a three-phase system and is often used in coal and ore processing. The produced agglomerates in this process can be easily separated from the remaining suspension. The precise quantification of the wetting properties and adhesion strength between suspended particles and binding liquid droplets is a scientific challenge. An accurate technique suitable for adhesion force measurements in three-phase systems with micrometer-scale particles is Fluidic Force Microscopy (FluidFM®). An experimental setup with optical control is being developed to measure adhesion forces between droplets and flat/rough surfaces. This will enable precise measurements of adhesion forces between solid EnAM crystals and binding liquid droplets. Based on these measurements, optimal agglomeration conditions can be selected in the future to improve selective wet agglomeration with respect to recycling processes.
The aim of this work was to develop a novel method for studying the 3D morphology of agglomerates obtained by spherical agglomeration. It has been found, that the combination of shock-freezing the samples in a mixture of ethanol and dry ice followed by an X-ray microtomography measurement leads to useful results. Hereby, the image quality for low absorbing material like the used graphite was enhanced by propagation-based X-ray microtomography, which results in phase contrast images. We also discuss our 3D image post-processing routine, which is used to determine the morphology parameters sphericity, fractal dimension and packing density. Furthermore, a two-dimensional kernel density estimation is used to calculate the joint probability density of agglomerate size and the morphology parameter. In future, this method will be used to determine the morphological behaviour of agglomerates during the different phases of spherical agglomeration.
Hydrological variability is a key factor in structuring biotic and abiotic processes in river ecosystems and is of particular importance to fish populations. We used 171 hydrological indices (HI) and young-of-the-year (YOY) fish abundances as indicators of reproductive success to compare species' response patterns to high and low flows on short-, intermediate-, and long-term scales. Our study included 13 common fish species in headwater streams of North Rhine-Westphalia, Germany. Generalized linear models using YOY abundances and HI on high- and low-flow patterns explained on average 64 % of the variability. HI calculated from long time series worked better than HI describing short- and intermediate-term high- and low flows. Species' reproductive success response to low flow HI depended on specific ecological traits whereas high flow HI differentially affected species according to their life history strategies. Equilibrium strategists responded negatively to high frequency and magnitude along with late timing of high flow, while periodic and opportunistic species mostly thrived under these conditions. We identified four species traits that mediated these differences between life history strategies. The reproductive success of species with low relative fecundity, large eggs and larvae, and long incubation periods was negatively impacted by the high frequency, high magnitude, and late timing of high flows. Conversely, the reproductive success of species with high relative fecundity, short incubation periods and small eggs and larvae was fostered by strong, frequent, and late high flows. The consideration of the relationship between reproductive success, life history, and fish species traits over several years under a range of flows is a novel step towards the implementation of measures to mitigate negative impacts and enhance conditions for successful fish reproduction.
Since the beginning of 2023, the so-called reusable packaging obligation has been in place in Germany in order to reduce the amount of waste from takeaway packaging. Catering companies will then be obliged to offer reusable packaging as an alternative to disposable plastic takeaway packaging. As part of the pilot project ‘Mehrweg Modell Stadt’ (‘Reusable city model’), an open infrastructure for reusable cups is in trial in Mainz and Wiesbaden. The project was subjected to a scientific monitoring process, which included the implementation of quantitative surveys among various stakeholders within the value chain, namely consumers, catering companies, and other companies engaged in the project. This was conducted over two time periods: August 2023 to September 2023, and February to March 2024. The results show a discrepancy between consumers’ attitudes and their actual behavior: Despite a high level of sustainability awareness and perceived positive benefits of reusable packaging, perceived barriers stand in the way of actual use. The biggest challenges for companies are the lack of consumer demand, practical handling and hygiene requirements. The results of this quantitative social research provide important insights for the development of targeted measures to promote the use of reusable packaging in takeaway catering and contribute to the discussion on closing the attitude–behavior gap along the entire value chain.
More and more universities are recognizing their role model and creative function in society and are acting accordingly - also in terms of mobility. In this way, universities can make an important contribution to climate protection, as mobility is responsible for more than 20 percent of global greenhouse gas emissions. The GreenMetric ranking also takes the area of mobility into account via the Transportation category, which is weighted at 18%. This paper uses the example of the Environmental Campus Birkenfeld at Trier University of Applied Sciences, Germany, to show what opportunities universities in rural areas have to reduce transportation-related emissions of students and employees. The possibilities of avoiding transportation as well as different solutions for the reduction of transportation-related greenhouse gas emissions are discussed. Furthermore, conflicts of objectives inherent to the university system in the area of mobility are considered, especially in the area of internationalization.
Digital transformation is both an opportunity and a challenge. To take advantage of this opportunity for humans and the environment, the transformation process must be understood as a design process that affects almost all areas of life. In this paper, we investigate AI-Based Self-Adaptive Cyber-Physical Process Systems (AI-CPPS) as an extension of the traditional CPS view. As contribution, we present a framework that addresses challenges that arise from recent literature. The aim of the AI-CPPS framework is to enable an adaptive integration of IoT environments with higher-level process-oriented systems. In addition, the framework integrates humans as actors into the system, which is often neglected by recent related approaches. The framework consists of three layers, i.e., processes, semantic modeling, and systems and actors, and we describe for each layer challenges and solution outlines for application. We also address the requirement to enable the integration of new networked devices under the premise of a targeted process that is optimally designed for humans, while profitably integrating AI and IoT. It is expected that AI-CPPS can contribute significantly to increasing sustainability and quality of life and offer solutions to pressing problems such as environmental protection, mobility, or demographic change. Thus, it is all the more important that the systems themselves do not become a driver of resource consumption.
In the past decade, research on measuring and assessing the environmental impact of software has gained significant momentum in science and industry. However, due to the large number of research groups, measurement setups, procedure models, tools, and general novelty of the research area, a comprehensive research framework has yet to be created. The literature documents several approaches from researchers and practitioners who have developed individual methods and models, along with more general ideas like the integration of software sustainability in the context of the UN Sustainable Development Goals, or science communication approaches to make the resource cost of software transparent to society. However, a reference measurement model for the energy and resource consumption of software is still missing. In this article, we jointly develop the Green Software Measurement Model (GSMM), in which we bring together the core ideas of the measurement models, setups, and methods of over 10 research groups in four countries who have done pioneering work in assessing the environmental impact of software. We briefly describe the different methods and models used by these research groups, derive the components of the GSMM from them, and then we discuss and evaluate the resulting reference model. By categorizing the existing measurement models and procedures and by providing guidelines for assimilating and tailoring existing methods, we expect this work to aid new researchers and practitioners who want to conduct measurements for their individual use cases.
Social media data are transforming sustainability science. However, challenges from restrictions in data accessibility and ethical concerns regarding potential data misuse have threatened this nascent field. Here, we review the literature on the use of social media data in environmental and sustainability research. We find that they can play a novel and irreplaceable role in achieving the UN Sustainable Development Goals by allowing a nuanced understanding of human-nature interactions at scale, observing the dynamics of social-ecological change, and investigating the co-construction of nature values. We reveal threats to data access and highlight scientific responsibility to address trade-offs between research transparency and privacy protection, while promoting inclusivity. This contributes to a wider societal debate of social media data for sustainability science and for the common good.
Additive manufacturing is an essential tool in innovative production processes. The extended degrees of freedom offer much potential in usage, construction, and product design. Rising raw material and energy costs, constantly increasing environmental requirements, and the increasing demand for resource-saving products represent a paradigm shift in classic production processes.
In addition to the purely energetic evaluation, developing energy models is a method to determine energy consumption and reduce it in the long term. The specific energy consumption model, also known as the SEC model, allows a quick estimation of energy consumption by multiplying the SEC with a unit like the mass of the workpiece, the manufacturing time, or the exposed area. Here, high dependence on the used machine, the considered peripheral devices, and the geometry are noticeable.
Previous studies, such as those by Kellens et al. and Baumers et al., have laid the basis for understanding the energy demands of PBF-LB/M processes. Various energy models have subsequently been proposed, including those by Paul and Anand, Yi et al., Lv et al., and Hui et al. These models are often limited by their specificity to sub-processes or subsystems. This results in limitations in their applicability to other manufacturing machines or inaccuracies in energy consumption predictions. The simulation accuracy ACC is mostly in the range of 90% with the limitation of small sample sizes. Moreover, nearly, all these models rely heavily on process time information, making the accuracy of their simulations largely dependent on the quality of the underlying time model.
In the following study, two manufacturing machines of the PBF-LB/M process are analyzed and compared with other studies. The aim is to analyze the power and resource consumption to use these data to build an improved energy model with a high accuracy, which can be used as an additional parameter in the adapted design methodology. Furthermore, potential savings are derived from the load curves.
Diadromous fish have exhibited a dramatic decline since the end of the 20th century. The allis shad (Alosa alosa) population in the Gironde-Garonne-Dordogne (GGD) system, once considered as a reference in Europe, remains low despite a fishing ban in 2008. One hypothesis to explain this decline is that the downstream migration and growth dynamics of young stages have changed due to environmental modifications in the rivers and estuary. We retrospectively analysed juvenile growth and migration patterns using otoliths from adults caught in the GGD system 30 years apart during their spawning migration, in 1987 and 2016. We coupled otolith daily growth increments and laser ablation inductively-coupled plasma mass spectrometry measurements of Sr:Ca, Ba:Ca, and Mn:Ca ratios along the longest growth axis from hatching to an age of 100 days (i.e., during the juvenile stage). A back-calculation allowed us to estimate the size of juveniles at the entrance into the brackish estuary. Based on the geochemistry data, we distinguished four different zones that juveniles encountered during their downstream migration: freshwater, fluvial estuary, brackish estuary, and lower estuary. We identified three migration patterns during the first 100 days of their life: (a) Individuals that reached the lower estuary zone, (b) individuals that reached the brackish estuary zone, and (c) individuals that reached the fluvial estuary zone. On average, juveniles from the 1987 subsample stayed slightly longer in freshwater than juveniles from the 2016 subsample. In addition, juveniles from the 2016 subsample entered the brackish estuary at a smaller size. This result suggests that juveniles from the 2016 subsample might have encountered more difficult conditions during their downstream migration, which we attribute to a longer exposure to the turbid maximum zone. This assumption is supported by the microchemical analyses of the otoliths, which suggests based on wider Mn:Ca peaks that juveniles in 2010s experienced a longer period of physiological stress during their downstream migration than juveniles in 1980s. Finally, juveniles from the 2016 subsample took longer than 100 days to exit the lower estuary than we would have expected from previous studies. Adding a new marker (i.e., Ba:Ca) helped us refine the interpretation of the downstream migration for each individual.
Evolution of stock market efficiency in Europe: Evidence from measuring periods of inefficiency
(2024)
This study introduces novel measures to quantify periods of market inefficiency, enabling precise analysis of their evolution over time and effective comparisons across markets or groups of markets. These measures are applied to an extensive dataset comprising stock indices from 25 European countries from 2007 to 2022. The empirical findings reveal a 20% increase in market inefficiency across Europe, primarily driven by heightened average inefficiencies in the stock markets of the group of developed European countries such as Germany and the Scandinavian countries.
Reliability of a clinical sensory test battery in patients with spine-related leg and arm pain
(2024)
Background: The current standard to evaluate the presence of somatosensory dysfunctions is quantitative sensory testing, but its clinical utility remains limited. Low-cost and time-efficient clinical sensory testing (CST) batteries have thus been developed. Recent studies show moderate to substantial reliability in populations with neuropathic pain. This study evaluates the inter- and intra-tester reliability of people with spine-related leg and arm pain, representing mixed pain mechanisms.
Methods: Fifty-three patients with spine-related leg (n = 41) and arm pain (n = 12) attended three CST sessions. The CST battery consisted of eleven tests, determining loss and gain of sensory nerve function. CST was performed by the same investigator twice and by an additional investigator to determine inter- and intra-tester reliability. Fleiss' (inter-tester) and Cohen's (intra-tester) kappa were calculated for dichotomized and intraclass correlation coefficients (ICC) for continuous outcomes.
Results: Fleiss' kappa varied among modalities from fair to substantial (κ = 0.23–0.66). Cold, warm, and vibration detection thresholds and cold and pressure pain thresholds reached kappa >0.4 (moderate to substantial reliability). Cohen's kappa ranged from moderate to substantial (κ = 0.45–0.66). The reliability of the windup ratio was poor (ICC <0.18).
Conclusion: CST modalities with moderate to substantial inter-tester reliability could be of benefit as a screening tool. The moderate to substantial intra-tester reliability for all sensory modalities (except windup ratio) supports their potential use in clinical practice and research to monitor somatosensory changes over time in patients with spine-related limb pain of mixed pain mechanisms.
Significance: We already know that most modalities of clinical sensory test (CST) batteries achieve moderate to substantial inter- and intra-tester reliability in populations with neuropathic pain.
This study evaluates the reliability of a CST battery in populations with mixed pain mechanisms. We found inter-tester reliability varied from poor to substantial for sensory modalities, questioning the value of some CST modalities. The CST battery showed moderate to substantial intra-tester reliability, suggesting its usefulness to monitor sensory changes over time in this cohort.
Background: The environmental impact of electric scooters has been the subject of critical debate in the scientific community for the past 5 years. The data published so far are very inhomogeneous and partly methodologically incomplete. Most of the data available in the literature suffer from an average bias of 34%, because end-of-life (EOL) impacts have not been modelled, reported or specified. In addition, the average lifetime mileage of shared fleets of e-scooters, as they are operated in cities around the world, has recently turned out to be much lower than expected. This casts the scooters in an unfavourable light for the necessary mobility transition. Data on impact categories other than the global warming potential (GWP) are scarce. This paper aims to quantify the strengths and weaknesses of e-scooters in terms of their contribution to sustainable transport by more specifically defining and extending the life cycle assessment (LCA) modelling conditions: the modelling is based on two genuine material inventories obtained by dismantling two different e-scooters, one based on a traditional aluminium frame and another, for the first time, based on plastic material.
Results: This study provides complete inventory data to facilitate further LCA modelling of electric kick scooters. The plastic scooter had a 26% lower lifetime GWP than the aluminium vehicle. A favourable choice of electric motor promises a further reduction in GWP. In addition to GWP, the scooter's life cycles were assessed across seven other impact categories and showed no critical environmental or health impacts compared to a passenger car. On the other hand, only the resource extraction impact revealed clear advantages for electric scooters compared to passenger cars.
Conclusions: Under certain conditions, scooters can still be an important element of the desired mobility transition. To assure a lifetime long enough is the crucial factor to make the electric scooter a favourable or even competitive vehicle in a future sustainable mobility system. A scooter mileage of more than 5400 km is required to achieve lower CO2eq/pkm emissions compared to passenger cars, which seems unlikely in today's standard use case of shared scooter fleets. In contrast, a widespread use of e-scooters as a commuting tool is modelled to be able to save 4% of greenhouse gas (GHG) emissions across the German mobility sector.
Dielectric properties of unidirectional and biaxial flax/epoxy composites at frequencies up to 1 GHz
(2023)
The relative permittivity of flax/epoxy composites in unidirectional and biaxial orientations was mapped in the frequency range of 1 kHz to 200 kHz, and for the first time in the range of 1 MHz to 1 GHz. In addition, permittivity was investigated for the first time in the temperature range between − 20 °C and 50 °C. These composites, produced using the vacuum infusion process, are increasingly used for sustainable and lightweight structural components in the automotive industry. The relative permittivity was determined using a self-developed plate capacitor with an LCR bridge and an impedance analyzer. An examination of the microstructure of the flax/epoxy composites shows that the fibers are disordered in the composite, resulting in local variations in fiber volume fraction. Furthermore, it was shown that the matrix also infiltrates into the fiber itself, resulting in an increase of the matrix fraction. It was found that unidirectional fabrics had a higher relative permittivity than biaxial fabrics, due to a higher fiber volume fraction and lower proportion of epoxy. The results suggest that it is the fiber volume fraction, rather than the manufacturing process and fiber orientation, that primarily determines the relative permittivity. It was also found that the permittivity continues to decrease below room temperature and thus behaves in a manner typical of the material in this temperature range as well.
Purpose – The COVID-19 pandemic has had a significant impact on the food tourism industry, leading to business closures and a drop in demand. In response to this challenge, virtual food tourism experiences such as VR have emerged as an alternative to traditional in-person experiences. Aim of this paper is to model consumer adoption of virtual food tourism by integrating the Diffusion of Innovation Theory and the Self-determination Theory.
Methodology/Design/Approach – The Diffusion of Innovation Theory explains the process of innovation adoption, while the Self-determination Theory focuses on consumer motivation. This article proposes that intrinsic (autonomy, relatedness, and competence) and extrinsic (relative advantage, complexity, compatibility, trialability, and observability) motivating factors influence virtual food tourism adoption.
Findings – The study suggests that extrinsic motivators can act as mediators between intrinsic motivation and adoption intention. Integrating these two theories provides a comprehensive understanding of the motivations and mechanisms driving virtual food tourism adoption. It also paves the way for the exploration of intrinsic and extrinsic motivations and specific mechanisms underlying adoption behaviours.
Originality of the research – Destinations, businesses, and policy makers can better navigate the changing landscape of food tourism and leverage the potential of virtual food tourism to create engaging, accessible, and culturally enriching experiences.
Ephemeroptera, Plecoptera and Trichoptera are three orders of freshwater macroinvertebrates with a short terrestrial adult life-stage that they use to disperse by flying upstream. This aerial dispersal can be assisted by native riparian forest, but regional variation has not yet been empirically tested. In this study we compared the EPT community of 153 sampling sites located in freshwater streams in four European regions (Central Plains, Central Highlands, Alps, Iberia). In each site, we assessed the EPT community dispersal ability using the Species Flying Propensity index. We also calculated the native deciduous forest cover in the riparian buffer and several environmental stressors such as saprobic pollution or catchment anthropization. Finally, we tested which of these parameters have a significant effect on the EPT community. In the Central Highlands and in Iberia, the share of weak dispersers increased with native deciduous forest cover, indicating a positive effect on dispersal of EPTs. In the Central Plains and the Alps, no such effect was found. We conclude that the effect of native deciduous forest depends on regional landscape characteristics and the regional species pool, but considering the dispersal of the regional EPT communities is needed to create effective river management policies.
Evaluation of a blended learning approach on stratified care for physiotherapy bachelor students
(2023)
Background: Stratified models of care are valuable for addressing psychosocial factors which influence the outcome of patients with musculoskeletal disorders. Introducing such models in undergraduate training has the potential to propagate this knowledge with evidence and foster its implementation. The objective of this paper is to explore the perception and changes in the fear-avoidance beliefs of physiotherapy students participating in a developed blended learning course on stratified care.
Methodology: A mixed-methods with a convenient sample of two consecutive cohorts were given a blended learning course on stratified care for patients with low back pain. The blended learning course comprised scientific rudiments and application of stratified care in clinical practice conceptualised using the KERN’ 6-step approach. The exam scores, perceptions, performance on self-reflection-tests and pre- and post-scores on The Tampa Scale for Kinesiophobia for Physiotherapists’ (TSK-PT) were obtained. After gaining clinical experience, participants were invited to discuss their clinical experiences and perceptions in workshops. The quantitative data was analysed explorative-descriptively. The qualitative data was analysed following an inductive coding system with constant comparisons.
Results: Ninety-one participants consented to the evaluation (mean age = 22.9 ± 1.6 years), 66% were female. Exam scores correlated with time spent in training (r = 0.30) and scores on self-reflection-tests 1 and 2 (r = 0.40 and r = 0.41). Participants in both cohorts described the learning resources as promoting their interest in the subject (72% and 94%), up-to-date (91% and 93%) and helpful (91% and 97%). The fear-avoidance scores for participants decreased from 53.5 (± 9.96) to 40.1 (± 12.4) with a large effect size (d = 1.18). The regression model [F (2, 49) = 1151.2, p < 0.001] suggests that pre-TSK-PT and the interest of participants in the training predicted post-TSK-PT. The workshop participants (n = 62) all worked in clinical practice. Emerging from the analysis were 4 categories (evolving to maturity in practice, perceiving determinants of stratified care, strategising for implementation and adopting an outlook for future practice).
Conclusion: The quality of engagement in learning, training strategy and interest in the subject contributes immensely to learning outcomes. This blended learning course was successful in reducing kinesiophobia and influencing the participants’ attitude towards care with the potential of being translated into long-term practice.
