Research suggests that sedentary behavior is negatively associated with cognitive outcomes. Interrupting prolonged sitting has been shown to improve cognitive functions, including executive functioning, which is important for academic performance. No research has been conducted on the effect of standing on EF in VET students, who make up a large proportion of the adolescent population and who are known to sit more than other students of this age. In this study, we investigated the acute effects of reducing SB by short (...) time standing on EF in vocational education and training students. In a randomized crossover study, 165 VET students were first taught for 15 min in seated position. After this, they performed while seated the Letter Memory Test for updating, and the Color Shape Test for shifting and inhibition. Students were randomly assigned to a sitting or standing condition. All students were taught again for 15 min and then took the same tests in the condition they were allocated to, respectively, standing or seated. After 1 week, the test procedure was repeated, in which students switched conditions. Mixed model analyses showed no significant effect of sitting or standing on updating, shifting, or inhibition. Also, no significant differences were found for the order of condition on updating, shifting, or inhibition. Our results suggest that 40 min of standing does not significantly influence EF among VET students. (shrink)

While executive functions and self-regulated learning strategy use have been found to be related in several populations, this relationship has not been studied in adult online distance education. This is surprising as self-regulation, and thus using such strategies, is very important here. In this setting, we studied the relation between basic executive functions and reported SRL-strategy use within a correlational design with 889 adult online distance students. In this study, we performed regression analyses and took age and processing speed into (...) consideration, as processing speed and EFs decrease with age, whereas self-regulation is reported to increase with age. Cognitively measured working memory was not related to reported SRL-strategy use in adult ODE students. Thus, even though the SRL-components within the strategies seem to elicit working memory, reported SRL-strategy use is not related to the functioning of this basic EF. This means that if SRL-strategy use needs to be increased in adult ODE students, training of working memory might not be an effective manner for achieving that goal. Better shifting and processing speed were related to less reported SRL-strategy use, which might suggest that SRL-strategies might be used to compensate for lower shifting and lower processing speed. With increasing age, the number of contacts with peers or teachers decreases. This latter finding might be of relevance during the pandemic since contacts with others is importance during lockdown.

Background: Dementia care at home often involves decisions in which the caregiver must weigh safety concerns with respect for autonomy. These dilemmas can lead to situations where caregivers provide care against the will of persons living with dementia, referred to as involuntary treatment. To prevent this, insight is needed into how family caregivers of persons living with dementia deal with care situations that can lead to involuntary treatment. Objective: To identify and describe family caregivers’ experiences regarding care decisions for situations (...) that can lead to involuntary treatment use in persons living with dementia at home. Research design: A qualitative descriptive interview design. Data were analysed using the Qualitative Analysis Guide of Leuven. Participants and research context: A total of 10 family caregivers providing care for 13 persons living with dementia participated in in-depth semi-structured interviews. Participants were recruited by registered nurses via purposive sampling. Ethical consideration: The study protocol was approved by the Ethics Committee of the University Hospitals Leuven and the Medical Ethical Test Committee Zuyderland. Findings: Family caregivers experience the decision-making process concerning care dilemmas that can lead to involuntary treatment as complicated, stressful and exhausting. Although they consider safety and autonomy as important values, they struggle with finding the right balance between them. Due to the progressive and unpredictable nature of dementia, they are constantly seeking solutions while they adapt to new situations. Family caregivers feel responsible and experience social pressure for the safety of persons living with dementia. They may be blamed if something adverse happens to the persons living with dementia, which increases an already stressful situation. Their experience is influenced by characteristics of the care triad such as practical and emotional support, knowledge, and previous experiences. Discussion and conclusion: To prevent involuntary treatment, professionals need to proactively inform family caregivers, and they need to support each other in dealing with complex care situations.

With modern technological advances, distance education has become an increasingly important education delivery medium for, for example, the higher education provided by open universities. Among predictive factors of successful learning in distance education, the effects of non-cognitive skills are less explored. Grit, the dispositional tendency to sustain trait-level passion and long-term goals, has raised much research interest and gained importance for predicting academic achievement. The Grit Questionnaire, measuring Perseverance of Effort and Consistency of Interests, has been shown to be a (...) reliable instrument in traditional university student populations. However, the measurement and predictive validity of this questionnaire is still unknown for adult distance education university students who differ from traditional students in various ways. Based on a sample of 2,027 students from a distance education university, this study assessed the psychometric properties of the two-factor structure grit measured by the Grit Questionnaire. The findings suggest that the short form of the Grit Questionnaire is a potentially useful assessment tool for measuring the grit construct for distance learning higher education and that the Consistency of Interests factor is especially relevant to consider the improvement of learning performance for distance education in terms of courses credit and exam attempts. The measurement precision of the Perseverance of Effort factor, however, should be improved in future research to provide higher measurement accuracy and broader item coverage. (shrink)

Regular musical activity as a complex multimodal lifestyle activity is proposed to be protective against age-related cognitive decline and Alzheimer’s disease. This cross-sectional study investigated the association and interplay between musical instrument playing during life, multi-domain cognitive abilities and brain morphology in older adults from the DZNE-Longitudinal Cognitive Impairment and Dementia Study study. Participants reporting having played a musical instrument across three life periods were compared to controls without a history of musical instrument playing, well-matched for reserve proxies of education, (...) intelligence, socioeconomic status and physical activity. Participants with musical activity outperformed controls in global cognition, working memory, executive functions, language, and visuospatial abilities, with no effects seen for learning and memory. The musically active group had greater gray matter volume in the somatosensory area, but did not differ from controls in higher-order frontal, temporal, or hippocampal volumes. However, the association between gray matter volume in distributed frontal-to-temporal regions and cognitive abilities was enhanced in participants with musical activity compared to controls. We show that playing a musical instrument during life relates to better late-life cognitive abilities and greater brain capacities in OA. Musical activity may serve as a multimodal enrichment strategy that could help preserve cognitive and brain health in late life. Longitudinal and interventional studies are needed to support this notion. (shrink)

What is the value of an early diagnosis of dementia in the absence of effective treatment? There has been a lively scholarly debate over this question, but until now patients have not played a large role in it. Our study supplements biomedical research into innovative diagnostics with an exlporation of its meanings and values according to patients. Based on seven focusgroups with patients and their care-givers, we conclude that stakeholders evaluate early diagnostics with respect to whether and how they expect (...) it to empower their capacity to care. They value it, for instance, with respect to whether it explains experienced complaints, allows to start a process of psychological acceptance and social adaptation to the expected degeneration, contributes to dealing with anxieties, informs adequately about when to start preparing for the end of life, informs the planning of a request for euthanasia, or allows society to deal with a growing amount of dementia patients. Our study suggests that information about disease is considered ‘harmful’ or ‘premature’ when recipients feel unable to act on that information in their care. The results of this research offers input to further ethical research. It invites to adopt a care perspective in evaluation and to seek ways to prevent the ‘harm’ that such diagnostic methods can bring about. (shrink)

Artefacts can influence our actions in several ways. They can be instruments, enabling and facilitating actions, where their presence affects the number and quality of the options for action available to us. They can also influence our actions in a morally more salient way, where their presence changes the likelihood that we will actually perform certain actions. Both kinds of influences are closely related, yet accounts of how they work have been developed largely independently, within different conceptual frameworks and for (...) different purposes. In this paper I account for both kinds of influences within a single framework. Specifically, I develop a descriptive account of how the presence of artefacts affects what we actually do, which is based on a framework commonly used for normative investigations into how the presence of artefacts affects what we can do. This account describes the influence of artefacts on what we actually do in terms of the way facts about those artefacts alter our reasons for action. In developing this account, I will build on Dancy’s (2000a) account of practical reasoning. I will compare my account with two alternatives, those of Latour and Verbeek, and show how my account suggests a specification of their respective key concepts of prescription and invitation. Furthermore, I argue that my account helps us in analysing why the presence of artefacts sometimes fails to influence our actions, contrary to designer expectations or intentions. (shrink)

mechanism" is frequently encountered in the social science literature, but there is considerable confusion about the exact meaning of the term. The article begins by addressing the main conceptual issues. Use of this term is the hallmark of an approach that is critical of the explanatory deficits of correlational analysis and of the covering-law model, advocating instead the causal reconstruction of the processes that account for given macro-phenomena. The term "social mechanisms" should be used to refer to recurrent processes generating (...) a specific kind of outcome. Explanation of social macro-phenomena by mechanisms typically involves causal regression to lower-level elements, as stipulated by methodological individualism. While there exist a good many mechanism models to explain emergent effects of collective behavior, we lack a similarly systematic treatment of generative mechanisms in which institutions and specific kinds of structural configurations play the decisive role. Key Words: causal regression • correlational analysis • emergent effects • micro-macro processes • social mechanisms • structural determinants. (shrink)

Trust is a central dimension in the relation between human beings and technologies. In many discourses about technology, the relation between human beings and technologies is conceptualized as an external relation: a relation between pre-given entities that can have an impact on each other but that do not mutually constitute each other. From this perspective, relations of trust can vary between _reliance_, as is present for instance in technological extensionism, and _suspicion_, as in various precautionary approaches in ethics that focus (...) on technological risks. Against these two interpretations of trust, this article develops a third one. Based on a more internal account of the relations between human beings and technologies, it becomes possible to see that every technological development puts at stake what it means to be a human being. Using technologies, then, implies trusting ourselves _to_ technologies. We argue that this does not imply an uncritical subjection to technology. Rather, recognizing that technologies help to constitute human subjectivity implies that human beings can get actively involved in processes of technological mediation. Trust then has the character of _confidence_: deliberately trusting oneself _to_ technology. (shrink)

Democracy depends on a vivid public sphere, where ideas disseminate into the public and can be discussed – and challenged - by everyone. Journalism has contributed significantly to this social mediation by reducing complexity, providing information on salient topics and (planned) political solutions. The digital transformation of the public sphere leads to new forms of media provision, distribution, and use. Journalism has struggled to adapt to the new conditions. Journalistic news values, relevant to democracy, are being replaced by ones relevant (...) to social media platforms’ attention seeking business model. We plead for a broad public debate about the ongoing platformization and about possible policies to ensure a media system that serves and strengthens democracy. (shrink)

As COVID-19 continues to spread, a variety of COVID-19 tracking apps have been introduced to help contain the pandemic. Deployment of this technology poses serious challenges of effectiveness, technological problems and risks to privacy and equity. The ethical use of CTAs depends heavily on the protection of voluntariness. Voluntary use of CTAs implies not only the absence of a legal obligation to employ the app but also the absence of more subtle forms of coercion such as enforced exclusion from certain (...) social and work activities. The protection of individual rights to voluntary use can be enhanced through an ethics by design approach in the development of CTAs that treat the introduction of CTAs for what it is: a complete novelty that is being tested for the first time in democracies.

Recent developments around the sharing economy bring to the fore questions of governability and broader societal benefit—and subsequently the need to explore effective means of public governance, from nurturing, on the one hand, to restriction, on the other. As sharing is a predominately urban phenomenon in modern societies, cities around the globe have become both locus of action and central actor in the debates over the nature and organization of the sharing economy. However, cities vary substantially in the interpretation of (...) potential opportunities and challenges, as well as in their governance responses. Building on a qualitative comparative analysis of 16 leading global cities, our findings reveal four framings of the sharing economy: ‘societal endangerment,’ ‘societal enhancement,’ ‘market disruption,’ and ‘ecological transition.’ Such framings go hand in hand with patterned governance responses: although there is considerable heterogeneity in the combination of public governance strategies, we find specific configurations of framings and public governance strategies. Our work reflects the political and ethical debates on various economic, social, and moral issues related to the sharing economy, and contributes to a better understanding of the field-level institutional arrangements—a prerequisite for examining moral behavior of sharing economy organizations.

There is a strong interconnection between the social and environmental spheres. The efforts of monitoring and forecasting of disastrous events can illustrate benefits and threats of technicization and science. In ecophilosophy the forecasting of hazards is today extremely needed. It is not about creating theoretical unified structures or practical return to holistic harmony of a primordial man with nature. It is about, as Félix Guattari once held it, the complexity of the relationship between humans and their natural environment. Though the (...) desired maintenance of the conflict between industrial society and natural systems now seems impossible, we still can start moving towards it: theoretically, by developing eco-philosophical ideas, and practically, monitoring and forecasting catastrophes and disasters, to protect human life and health and, as eco-philosophers would say, keep land usable for human purposes. The topic of the earthquakes forecast today is more in demand than ever. (shrink)

Radioactivity accompanied by ionizing radiation has always existed on the Earth, as well as in space, and so in every living tissue there are traces of radioactivity. With the discovery of the said radiation and identifying its effects on the human body, the fear of this phenomenon appeared. At high doses radiation causes serious tissue damages, while at small doses it can cause cancer and induce genetic defects. The best antidote for fear is knowledge. It is important to know the (...) margins safety of radiation for human life. As a result, the topic of radioactive contamination of the environment has now become one of the most significant. In recent years the radon problem is a subject of a wide debate of geologists, geophysicists, ecologists, physicians, specialists in radiometry, and, of course, philosophers and sociologists, since the need for assessing the potential radon danger concerns human lives, human functions in society, and human future.

This paper offers a contribution to ecophilosophy from the perspective of the scientific research of the environment. The problem considered in the paper deals with a specific issue of environmental risk, namely, the problem of radon ionizing radiation and the highest permissible security norms of it. This problem, now rarely discussed in ecological communities, is one of more important for humankind’s health and safe existence. The awareness of harmful and beneficial biological effects of various environmental factors is a basic step (...) towards ensuring the security of public health. The admissible norms of radon radiation are different in different countries. The article suggests possible causes of these differences and puts forward the thesis that today’s science alone is not a sufficient ground of resolving ecological problems. (shrink)
