Understanding and modulating CNS function in physiological as well as pathophysiological contexts remains a significant ambition in research and clinical applications. The investigation of the multifaceted CNS cell types including their interactions and contributions to neural function requires a combination of the state-of-the-art in vivo electrophysiology and imaging techniques. We developed a novel type of liquid crystal polymer (LCP) surface micro-electrode manufactured in three customized designs with up to 16 channels for recording and stimulation of brain activity. All designs include spare central spaces for simultaneous 2P-imaging. Nanoporous platinum-plated contact sites ensure a low impedance and high current transfer. The epidural implantation of the LCP micro-electrodes could be combined with standard cranial window surgery. The epidurally positioned electrodes did not only display long-term biocompatibility, but we also observed an additional stabilization of the underlying CNS tissue. We demonstrate the electrode’s versatility in combination with in vivo 2P-imaging by monitoring anesthesia-awake cycles of transgenic mice with GCaMP3 expression in neurons or astrocytes. Cortical stimulation and simultaneous 2P Ca2+ imaging in neurons or astrocytes highlighted the astrocytes’ integrative character in neuronal activity processing. Furthermore, we confirmed that spontaneous astroglial Ca2+ signals are dampened under anesthesia, while evoked signals in neurons and astrocytes showed stronger dependency on stimulation intensity rather than on various levels of anesthesia. Finally, we show that the electrodes provide recordings of the electrocorticogram (ECoG) with a high signal-to noise ratio and spatial signal differences which help to decipher brain activity states during experimental procedures. Summarizing, the novel LCP surface micro-electrode is a versatile, convenient, and reliable tool to investigate brain function in vivo.
Introduction: The use of social marketing strategies to induce the promotion of cognitive health has received little attention in research. The objective of this scoping review is twofold: (i) to identify the social marketing strategies that have been used in recent years to initiate and maintain health-promoting behaviour; (ii) to advance research in this area to inform policy and practice on how to best make use of these strategies to promote cognitive health.
Methods and analysis: We will use the five-stage methodological framework of Arksey and O'Malley. Articles in English published since 2010 will be searched in electronic databases (the Cochrane Library, DoPHER, the International Bibliography of the Social Sciences, PsycInfo, PubMed, ScienceDirect, Scopus). Quantitative and qualitative study designs as well as reviews will be considered. We will include those articles that report the design, implementation, outcomes and evaluation of programmes and interventions concerning social marketing and/or health promotion and/or promotion of cognitive health. Grey literature will not be searched. Two independent reviewers will assess in detail the abstracts and full text of selected citations against the inclusion criteria. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses flowchart for Scoping Reviews will be used to illustrate the process of article selection. We will use a data extraction form, present the results through narrative synthesis and discuss them in relation to the scoping review research questions.
Ethics and dissemination: Ethics approval is not required for conducting this scoping review. The results of the review will be the first step to advance a conceptual framework, which contributes to the development of interventions targeting the promotion of cognitive health. The results will be published in a peer-reviewed scientific journal. They will also be disseminated to key stakeholders in the field of the promotion of cognitive health.
Unintended nuclear war
(2021)
The aim of the study is to find out how SMEs used Social Media during Corona and how customers received it, to determine what should be continued or avoided by SMEs in the future. In this study, an interpretivist approach was adopted through problem-centred interviews with three SMEs. The second part of the study used an objectivist approach, where an online-based survey with a purpose sampling was conducted. The results were evaluated by means of thematic analysis.The SMEs interviewed considered Social Media essential during Corona. This was due to limited resources and the feeling of being overwhelmed by the situation. For customers a Social Media presence is also considered indispensable, and that the followership is based on the desire for the latest information. However, it also became clear that the survey participants do not believe the information on Social Media and prefer information on the website or at the location itself. No answers could be found about how the experts would answer sans or post Corona. Furthermore, due to anonymisation efforts, it was not possible to clarify the attitude of the survey participants specifically to the individual SMEs.
The dark side of Samsung’s value chain: The human costs of cobalt mining “BLOOD, SWEAT AND COBALT”
(2021)
Samsung has been implicitly linked to human rights abuses and wider social downgrading propagated within the Democratic Republic of Congo (DRC). Reports by different studies have shown artisanal cobalt mines (ASM) to exploit child labour and subject workers to perilous conditions. The IT multinational is dependent upon Congolese cobalt as a key element in lithiumion batteries used to produce their array of electronics. However, irresponsible cobalt sourcing practices undertaken by Tier 1 suppliers, Glencore and Huayou, have resulted in ASM operations being incorporated into Samsung’s global value chain, as Tier 2 suppliers. Analysis of the relationships underpinning Samsung’s cobalt value chain theoretical framework, highlights the presence of a relational governance structure, with captive elements among upstream Tier 1 and Tier 2 suppliers. Samsung is thereby reliant upon both Glencore and Huayou to transmit and enforce private codes of conduct down the value chain to expel human rights abuses. In conjunction, the DRC’s weak and unstable institutional environment has facilitated corruption and the improper enforcement of laws across the ASM industry. It is thereby imperative that Samsung takes ownership of the issues present within its value chain, as both Tier 1 suppliers and the Congolese government have failed to ensure responsible cobalt sourcing practices to date. This report recommends that Samsung adopt a holistic action plan, not only utilising their own resources and capabilities, but also those of critical stakeholders including Tier 1 suppliers, NGOs and the DRC and South Korean governments. Most prominently, this report suggests that supply chain transparency can be improved using certificates of origin and blockchain technology. Furthermore, it is recommended that poverty alleviation is targeted as a key measure through “Cobalt for Development”, an action plan designed to instigate both social and economic upgrading within ASM operations and the wider community. By employing a multi-scalar approach and addressing the issues inherent across multiple governance levels, Samsung can ensure a responsible source of cobalt be sustained.
This study will describe how the robotics industry evolved increasingly and a new phase of advanced robotics has emerged, and the relation between humans and robots in the same workplace. Problems of designing safer robots in human-machine interaction systems are urgent research topics in the field of industrial robotics. Many of the problems in industrial robotics are related not just to technological issues, but also to human-robot collaboration also will be discussed as an effective method to tackle this issue is the invention of Collaborative robots.
The present work aimed at investigating an extraction protocol based on consecutive steps of isoelectric point (pH ~ 4.25) mediated gum swelling and deproteinisation as an alternative method to produce flaxseed gum extracts of enhanced techno-functional characteristics. The osidic and proximate composition, structure conformation, flow behaviour, dynamic rheological and thermal properties of gums isolated from brown and golden flaxseeds were assessed. Gum extraction under near-to-isoelectric point conditions did not impair the extraction yield, residual protein and ash content, whilst it resulted in minor changes in the sugar composition of the flaxseed gum extracts. The deconvolution of the GPC/SEC chromatographs revealed the presence of four major polysaccharidic populations corresponding to arabinoxylans, rhamnogalacturonan–I and two AX-RG-I composite fractions. The latter appeared to minimise the intra- and interchain polymer non-covalent interactions (hydrogen bonding) leading to a better solvation affinity in water and lyotropic solvents. Golden flaxseed gums exerted higher molecular weight (Mw = 1.34–1.15 × 106 Da) and intrinsic viscosities (6.63–5.13 dL g−1) as well as better thickening and viscoelastic performance than the brown flaxseed gum exemplars. Golden flaxseed gums exhibited a better thermal stability compared to the brown flaxseed counterparts and therefore, they are suitable for product applications involving severe heat treatments.
Optimal mental workload plays a key role in driving performance. Thus, driver-assisting systems that automatically adapt to a drivers current mental workload via brain–computer interfacing might greatly contribute to traffic safety. To design economic brain computer interfaces that do not compromise driver comfort, it is necessary to identify brain areas that are most sensitive to mental workload changes. In this study, we used functional near-infrared spectroscopy and subjective ratings to measure mental workload in two virtual driving environments with distinct demands. We found that demanding city environments induced both higher subjective workload ratings as well as higher bilateral middle frontal gyrus activation than less demanding country environments. A further analysis with higher spatial resolution revealed a center of activation in the right anterior dorsolateral prefrontal cortex. The area is highly involved in spatial working memory processing. Thus, a main component of drivers’ mental workload in complex surroundings might stem from the fact that large amounts of spatial information about the course of the road as well as other road users has to constantly be upheld, processed and updated. We propose that the right middle frontal gyrus might be a suitable region for the application of powerful small-area brain computer interfaces.
Radar signal processing is a promising tool for vital sign monitoring. For contactless observation of breathing and heart rate a precise measurement of the distance between radar antenna and the patient’s skin is required. This results in the need to detect small movements in the range of 0.5 mm and below. Such small changes in distance are hard to be measured with a limited radar bandwidth when relying on the frequency based range detection alone. In order to enhance the relative distance resolution a precise measurement of the observed signal’s phase is required. Due to radar reflections from surfaces in close proximity to the main area of interest the desired signal of the radar reflection can get superposed. For superposing signals with little separation in frequency domain the main lobes of their discrete Fourier transform (DFT) merge into a single lobe, so that their peaks cannot be differentiated. This paper evaluates a method for reconstructing the phase and amplitude of such superimposed signals.
