This article concerns a phenomenon of elementary quantum mechanics that is quite counter-intuitive, very non-classical, and apparently not widely known: a quantum particle can get reflected at a potential step downwards. In contrast, classical particles get reflected only at upward steps. As a consequence, a quantum particle can be trapped for a long time (though not forever) in a region surrounded by downward potential steps, that is, on a plateau. Said succinctly, a quantum particle tends not to fall off a (...) table. The conditions for this effect are that the wave length is much greater than the width of the potential step and the kinetic energy of the particle is much smaller than the depth of the potential step. We point out how the topic is accessible with elementary methods, but also with mathematical rigor and numerically. (shrink)

O objetivo é investigar se a Dialética transcendental de Kant, ao se deter sobre ascondições que dão origem ao conflito da razão consigo mesma, não oferece ainda umareflexão acerca da regulação transcendental do discurso e da linguagem filosófica.

O objetivo do texto é apresentar, no escopo da filosofia crítica de Kant, as definições, complementares e contrastantes, de entusiamos e fanatismo como diferentes estados da mente e do ânimo. O argumento pretende que essa distinção, fundada na diferença entre sentimento e paixão, é importante não apenas como parte da descrição kantiana da dinâmica das afecções que produzem estados da mente, mas também como parte da avaliação dos sistemas filosóficos anteriores, ditos dogmáticos.

A tradução de Foucault da Antropologia de Kant, realizada como tese complementar à História da loucura na idade clássica e publicada pela primeira vez em 1964, é precedida, na edição que ora vem a lume (Vrin, 2008), de uma longa introdução originalmente apresentada à comissão julgadora e posteriormente omitida pelo autor – que contraria assim a recomendação da banca e prefere considerá-la como uma espécie de esboço preparatório ao dito “livro dos signos”, publicado em 1966 com o título de Les (...) mots et les choses – une archeologie des scienes humaines.1 Os anos que separam de sua publicação a redação desse estudo não puderam mitigar o valor das considerações de Foucault, que têm o duplo interesse de esclarecer a trajetória de seu pensamento no decorrer dos anos 60 e de instigar o interessado por Kant a quem sabe adotar novas perspectivas no estudo de sua filosofia.

After a “very personal” introduction, and a reference to how accurate indeed is the use of the “new window” metaphor by Ulanowicz and about what “can be seen through it”, the article dwells into the evolution of our understanding about the most general sources—material and/or non-material—of change and transformation; in order to examine further the item about the ways through which “information” can be a source of change and transformation also in pre-biotic processes, where commonly it is not taken into (...) account. Thus, the article argues the convergence between Ulanowicz’s and the Author’s treatments of—non only biotic—networks of configuration of processes (a central theme in Ulanowicz’s book). Finally, the article pays attention to how Ulanowicz’s vision through his “new Third Window”, can indeed help us transcend the non desirable division of contemporary culture into two isolated compartments (science and technology versus the humanities and ethics), which has contributed not only to the globalization of communications, transactions, knowledge and so on, but also to the globalization of multiple crisis of different sort that need to be solved if we want “a better world to be possible”.

This study attempts to analyse the relationship between two key psychological variables associated with performance in sports - Self-Determined Motivation and Competitive Anxiety - through Bayesian Networks analysis. We analysed 674 university students/athletes from 44 universities that competed at the University Games in México, with an average age of 21 years (SD = 2.07) and with a mean of 8.61 years’ (SD = 5.15) experience in sports. Methods: Regarding the data analysis, first a CHAID algorithm was carried out to determine (...) the dependence links between variables, and then a Bayesian networks was developed. The validation of the BN revealed AUC values ranging from 0.5 to 0.92. Subsequently, various instantiations were performed with hypothetical values applied to the “bottom” variables. Results showed two probability trees that have extrinsic motivation and amotivation at the top, while the anxiety/activation due to worries about performance was at the bottom of the probabilities. The instantiations carried out support the existence of these probabilistic relationships, demonstrating their scarce influence on anxiety about competition generated by the intrinsic motivation, and the complex probabilistic effect of introjected and identified regulation regarding the appearance of anxiety due to worry about performance.

In the context of business, interactions between individuals generate social systems that emerge anywhere within a corporation or in its relations with external agents. These systems influence the behaviors of individuals and, as a result, the collective actions we usually attribute to corporations. Social systems thus make a difference in processes of action that are often morally evaluated by internal and external agents to the firm. Despite this relevance, social systems have not yet been the object of specific attention in (...) the literature on moral agency in business. To fill this gap, I construct a theoretical framework based on Luhmann’s ideas on social systems and morality. In particular, I argue that morality is a phenomenon that occurs in communication, and an agent can engage in morality in three different ways (as a _moral factor_, an _expressive moral agent_, or a _reflective moral agent_) depending on the functions it plays in communicative interactions. Based on this framework, I argue that social systems in business can be considered moral agents of those types. (shrink)

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

The scientific literature highlights the risk of the appearance of internalizing and externalizing symptoms, together with difficulties in the academic area, linked to diagnosis of Attention Deficit Hyperactivity Disorder. This is normally assessed by teachers and primary caregivers, disregarding the self-perception of the adolescents themselves, which limits detection of this disorder at an evolutionary stage. Our aim was to analyze the psychometric properties of a self-report for ADHD in adolescence and its relationship with psychopathology and academic performance. This study assessed (...) an incidental sample of 267 students from secondary schools in the Region of Murcia, Spain, using the EDAH questionnaire adapted for self-report, in order to analyze its psychometric properties in assessing ADHD. The Youth Self-Report and the Brief Self-Control Scale were also used to determine their association with psychopathological, self-control and academic performance variables. An ADHD prevalence of between 3.7 and 13.1% was observed depending on the established cut-off point. The adapted EDAH showed adequate reliability indices and explained a high variance percentage. Adolescents with anxiety/depression difficulties, dissocial behavior, aggressiveness, and poor performance in mathematics showed a higher amount of ADHD symptoms. Moreover, self-control, dissocial behavior, age, and performance in Social Sciences acted as predictors of the disorder. The good psychometric properties of this questionnaire and its adequate correspondence with other variables of interest suggest it is an appropriate self-report instrument to assess ADHD in adolescence.

Our goal was to explore self‐care practices among men who have sex with men in the context of Mpox in Brazil. This study used qualitative research methods, including interviews and thematic analysis, to collect and analyze data from male participants across the Brazilian territory. The narratives unveil men's perspectives on self‐care, risk reduction, and health beliefs during the Mpox pandemic. Our findings highlight a multifaceted approach to self‐care among men, encompassing hygiene, physical contact management, mask usage, skin lesion vigilance, and (...) adherence to official guidelines. Men's attitudes toward sexual behaviors emphasize the importance of reducing sexual partners, practicing safe sex, and combating misinformation through accurate information dissemination. The development of these behaviors and self‐care practices can be facilitated by nurses guided by Dorothea Orem's Self‐Care Theory, supported by patient‐centered care, with strategies to address and confront the stigma associated with the disease and provide emotional support. Thus, the study underscores the pivotal role of self‐care in mitigating infection risks, especially in the context of emerging infectious diseases. It acknowledges the impact of socio‐cultural factors and healthcare policies on men's preventive measures. However, it also recognizes limitations, such as potential bias due to stigma concerns and a nonrepresentative sample. Ultimately, the research advocates for tailored education, promotion of gender equity, and healthcare empowerment to effectively manage health risks in such contexts. (shrink)

La discusión sobre las consecuencias políticas del pensamiento de L. Wittgenstein ha girado sobre la posibilidad de construir miradas críticas sobre lo social, su legitimidad, amplitud, fuerza, etc. Sin embargo, aproximar a Wittgenstein a una posición materialista, como la entendía L. Althusser, conduce a una comprensión diferente de la crítica, vinculada a la tarea de deconstruir el discurso filosófico que intenta unificar y organizar jerárquicamente las evidencias (certezas) constitutivas de los diferentes juegos de lenguaje en los que se despliega lo (...) social. Se intenta extraer de esta aproximación una distinción entre la filosofía como práctica teórica ideológica y como práctica teórica crítica. The discussion regarding the political consequences of Wittgenstein's thought has focused on the possibility of building critical approaches to the legitimacy, amplitude, strength, etc. of the social sphere. However, bringing Wittgenstein close to a materialist position as understood by L. Althusser leads to a different understanding of critique, linked to the deconstruction of the philosophical discourse that attempts to unify and hierarchically organize the certainties that are constitutive of the different language games in which the social is deployed. On the basis of this approach, the article attempts to draw a distinction between philosophy as ideological theoretical practice and as critical theoretical practice. (shrink)

Nicolas de Cues (1401-11 août 1464) assume pour l’essentiel la thèse érigénienne et alanienne de l’incognoscibilité de Dieu et de la quiddité des choses. Il développe et approfondit la conscience de la supériorité de la négation sur l’affirmation in divinis qui avait permis au Néoplatonisme Médiéval d’élaborer une théorie sémantique du langage en nette rupture avec le triptyque aristotélicien qui établit la nécessité d’une correspondance entre chose, pensée et signe : pour Nicolas de Cues, l’essence du langage est dans la (...) production d’un sens, et celui-ci peut être entièrement indépendant de la possibilité d’appréhension de son objet. La présente recherche entend démontrer que cette thèse de l’incognoscibilité divine est intimement liée à une autre thèse d’ordre épistémologique qui décrète radicalement que toute affirmation est une conjecture au sujet du réel et que notre esprit est dans l’impossibilité d’atteindre la vérité de façon adéquate. Il n’existe pas de connaissance humaine certaine, car la quiddité des choses qui détermine leurs essences véritables est inaccessible. (shrink)

Cet article a comme objetif analyser les liens possibles entre deux thèmes de grande relevance de la philosophie de Nicolas de Cues : la théophanie comme manifestation de Dieu et la filiatione dei ou visio Dei, comme modes de clairvoyance de l'infini divin. Cette « voie divine » de la connaissance est la fin d'un voyage où la créature « court » vers le fondement radical qui se révèle em tant que présence infinie dans le fini grâce une « vision (...) » intellectuelle. Le principe de la non-contradiction doit donc être remplacé par celui de la coïncidence des contraires ; cependant, ce dernier doit finalement être dépassé par l'ignorance savante. A son tour, selon Nicolas de Cues, dans cette vision théophanique, le « ne pas savoir » de la créature coincide avec le « savoir » que Dieu a de lui-même, c'est-à-dire de sa connaissance de soi comme infini et non pas en tant qu’une chose parmi d’autres. Dans la tradition néoplatonicienne latine, l’univers théorique où gravitent les concepts de monè, proódos et epistrophé (manence, procession et retour), Nicolas de Cues apporte cependant des nouveautés par rapport à ses prédécesseurs, comme Jean Scot Erigène, puisqu'il se lance dans une tentative ambitieuse d’utiliser la négativité comme outil d'un « discours ignorant » radical, c'est-à-dire un discours qui cherche une expression positive de la « racine » de cette relation paradoxale Créateur-créature. A travers l'itinéraire d'élaboration des noms divins et des énigmes de plus en plus « capables » d'orienter l'intellect vers cette vision du principe incompréhensible dans sa relation active de création/vision avec l'Univers, le Cardinal parcourt le chemin philosophique proposé dans son De coniecturis : une recherche sans fin de l'expression positive de Dieu à travers la négativité visant dépasser l’anonymat classique qui caractérise la tradition néoplatonicienne. Mots-clés : Nicolas de Cues, Visio de Dieu, Docte ignorance, infini, néoplatonisme. (shrink)

Burnout is characterized by emotional exhaustion and caused by exposure to excessive and prolonged stress related to job conditions. Moreover, burnout is highly prevalent among health care professionals. The aim of this study is, first, to examine the mediating role of social support over the effect of burnout in health care professionals and, second, to explore potential gender differences. A convenience sample of 1,035 health professionals from Ecuador, including 608 physicians and 427 nurses, was surveyed using the Maslach Burnout Inventory, (...) Social Support Survey, and General Health Questionnaire as measures of burnout, social support, and general health, respectively. Social support was found to mediate the negative effects of burnout on health regardless of gender. Differences across the three dimensions of burnout and health are further discussed, along with their implications for designing effective burnout interventions for health care professionals in Ecuador.

Training for sustainable development is an educational challenge of prime importance. Physical activity and sports in natural environments provide training committed to sustainability and environmental education. The objective of this study was to assess the effects of an undergraduate training program in Physical Activities and Sports in Natural Environments concerned with sustainable development. A total of 113 students from the Autonomous University of Madrid who are studying a Bachelor’s Degree in Physical Activity and Sports Sciences and a Master’s Degree in (...) Teacher Training for Secondary Education and High School were involved. Specifically, we aimed to assess the impact of this training program on three dimensions related to Environmental Education. Its effect was also examined bearing in mind students’ sex, age and educational profile. Mixed-methods were used: for the quantitative approach, data were collected with the Environmental Attitude in Physical Activities in Natural Environments validated scale; for the qualitative approach individual reflective diaries completed by students that attended the program were analyzed. The results show positive effects on the students regarding the three dimensions of Environmental Education, for both the sportive and educational training profiles. The quantitative results do not present significant differences concerning the gender variable, although the qualitative information shows that female students perceived a greater environmental sensitivity during their practices. Regarding the age variable, significant differences are found in the youngest students with an educational profile. To conclude, the study ratifies that the program carried out generated improvements in terms of knowledge, behaviors and attitudes toward the environment and sustainable development. Future research should use larger samples and consider other variables related to education for sustainability. (shrink)

En partant des derniers paragraphes de la cinquième parti du Discours de la Méthode, on a reconstitué la formulation cartésienne de la perception d’un autre moi. Les critères de l’usage du langage et de la plasticité du comportement ont été analysés à la lumière de l’idée d’une machine universelle et du test de Turing. On conclut de la faiblesse de l’argument cartésien sur l’irréductibilité de la pensée à un dispositif machinal. En tant qu’issue de la difficulté, on propose une révision (...) de la façon cartésienne de caractérisation de la pensée à partir du concept d’expérience, tout en abandonnant le thème d’une perception interne incommunicable et intémoignable.

Dans un contrepoint polémique au livre de A. Damásio, L'Erreur de Descartes, nous soutenons: que la thèse de l a «séparation» de l’âme et du corps permet, dans les écrits physiologiques de Descartes tels que le Traité de l'Homme, une réduction des fonctions végétative et sensitive aux processus mécaniques et naturels du corps humain; que l'in troduction d'une âme dans le corps se justifie, chez Descartes, par l'impossibilité de rendre raison de la rationalité du comportement humain et de la conscience (...) par les simples mécanismes physiologiques et la seule «disposition des organes». On montre, donc, que Descartes est, d'un côté, un des père s de la moderne approche neurologique qui est à l a base du livre de M. Damásio et, de l'autre, qu'il a vu d'avance une des limites d'une explication exclusivement neurologique de la complexité du comportement humain. (shrink)
