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.

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)

Uitgave ter gelegenheid van de vierhonderdste geboortedag van de Nederlandse jurist, diplomaat en schrijver Hugo de Groot (1583-1645).

For many decades, researchers have explored the true potential of human achievement. The expertise field has come a long way since the early works of de Groot (1965) and Chase and Simon (1973). Since then, this inquiry has expanded into the areas of music, science, technology, sport, academia and art. Despite the vast amount of research to date, the capability of study methodologies to truly capture the nature of expertise remains questionable. Some considerations include (i) the individual bias in (...) the retrospective recall of developmental activities, (ii) the ability to develop ecologically valid tasks, and (iii) difficulties capturing the influence of confounding factors on expertise. This article proposes that expertise research in electronic sports (esports) presents an opportunity to overcome some of these considerations. Esports involves individuals or teams of players that compete in video game competitions via human-computer interaction. Advantages of applying the expert performance approach in esports include (i) developmental activities are objectively tracked and automatically logged online, (ii) the constraints of representative tasks correspond with the real-world environment of esports performance, and (iii) expertise has emerged without the influence of guided systematic training environments. Therefore, this article argues that esports research provides an ideal opportunity to further advance research on the development and assessment of human expertise. (shrink)

This article examines Gerald Odonis' view on the nature of place as found in his commentary on the Sentences and in an anonymous question extant in manuscript Madrid, Biblioteca Nacional, 4229. Both texts defend a thoroughly un-Aristotelian conception of place as three-dimensional space. Odonis not only deviates from Aristotle's definition of place as the inner surface of a surrounding body, but also from the positions of his contemporaries, including fellow Franciscans. Despite some remarkable doctrinal similarities between Odonis' view and that (...) of Renaissance innovators like Francesco Patrizi and Bernardino Telesio, it seems unlikely that Gerald played a role in the rise of new conceptions of place in the sixteenth and seventeenth century. An edition of the anonymous Quaestio de loco is given in an appendix. (shrink)

In the context of a particular framework of emergent quantum mechanics, it is argued the emergent origin of the inertial mass of a physical system. Two main consequences of the theory are discussed: an emergent interpretation of the law of inertia and a derivation of the energy-time uncertainty relation.

This paper examines geometrical arguments from Galileo's Mechanics and Two New Sciences to discern the influence of the Aristotelian Mechanical Problems on Galileo's dynamics. A common scientific procedure is found in the Aristotelian author's treatment of the balance and lever and in Galileo's rules concerning motion along inclined planes. This scientific procedure is understood as a development of Eudoxan proportional reasoning, as it was used in Eudoxan astronomy rather than simply as it appears in Euclid's Elements. Topics treated include the (...) significance of the circle in Galileo's demonstrations, the substitution of rectilinear elements for heterogeneous factors like weight and curvilinear distance, and the way in which elements of a motion are used to measure other elements of the same motion. The indirectness of Galileo's proofs, his conception of speed as relative and comparative, and the meaning of his concept of moment all come into clearer focus. Conclusions are drawn about Galilean idealization, and also about the contrast of literal versus figural modes of explanation in Galileo's science. (shrink)

Albinism in Tanzania causes fierce health-related stigma. Little research has focused on the impact of stigma reduction strategies aiming to reduce albinism related stigma. Therefore, this research assessed the impact of two short video interventions among high school students in Tanzania on their attitude towards people with albinism: a contact intervention (n = 95) and an education intervention (n = 97). A mixed method design was used. Directly before and after the interventions impact was measured among all participants through the (...) Albinism Social Distance Scale for Adolescents (ASDS-A), knowledge items, and entertainment items. After these measurements focus group discussions were conducted, 16 in total (n = 80). Both interventions caused a significant increase in the levels of correct knowledge about albinism. The education intervention entailed a significant positive change in attitude measured through the ASDS-A, whereas the contact intervention did not have a significant effect. In terms of entertainment value, the respondents were more enthusiastic about the contact intervention. The study suggests that education interventions on their own can be a successful tool in decreasing albinism related stigma. Additionally, qualitative findings show many positive outcomes for the contact intervention. Therefore, we would recommend using a combination of these two interventions, which has also proved successful in the past. However, more research on the effect of a combination of the two strategies is recommended. (shrink)

Theodor Adorno's Aesthetic Theory offers one of the most powerful and comprehensive critiques of art and of the discipline of aesthetics ever written. The work offers a deeply critical engagement with the history and philosophy of aesthetics and with the traditions of European art through the middle of the 20th century. It is coupled with ambitious claims about what aesthetic theory ought to be. But the cultural horizon of Adorno's Aesthetic Theory was the world of high modernism, and much has (...) happened since then both in theory and in practice. Adorno's powerful vision of aesthetics calls for reconsideration in this light. Must his work be defended, updated, resisted, or simply left behind? This volume gathers new essays by leading philosophers, critics, and theorists writing in the wake of Adorno in order to address these questions. They hold in common a deep respect for the power of Adorno's aesthetic critique and a concern for the future of aesthetic theory in response to recent developments in aesthetics and its contexts.
