Physical activity and sedentary behaviour have been linked to the mental health of children and adolescents, yet the timing of behaviours may play a role in this relationship and clarifying this could inform interventions. We explored cross-sectional associations of PA and SED in varying time segments throughout the school day with the mental health of school-aged children and adolescents from rural Northeastern Ontario, Canada. A total of 161 students wore accelerometers for 8 days and completed a self-report survey. Mental health (...) was measured using the Strengths and Difficulties Questionnaire. Accelerometer-measured SED, light PA, and moderate and vigorous PA were estimated in the time-segments before school, school time, after school, and evenings. Associations were tested with multilevel linear regressions while adjusting for confounding factors. Students spent 72.6 min in MVPA, 209.0 min in LPA, and 621.0 min in SED per day. Daily SED was associated with less conduct problems. Evening LPA was inversely associated with hyperactivity, while SED was associated with hyperactivity and with peer problems before school, and during school. No associations were observed for MVPA, emotional symptoms, or prosocial behaviour. In conclusion, displacing SED with LPA in some specific periods of the day may benefit the mental health of students; taking this into account could strengthen interventions. (shrink)

Automatized scalable healthcare support solutions allow real-time 24/7 health monitoring of patients, prioritizing medical treatment according to health conditions, reducing medical appointments in clinics and hospitals, and enabling easy exchange of information among healthcare professionals. With recent health safety guidelines due to the COVID-19 pandemic, protecting the elderly has become imperative. However, state-of-the-art health wearable device platforms present limitations in hardware, parameter estimation algorithms, and software architecture. This paper proposes a complete framework for health systems composed of multi-sensor wearable health (...) devices, high-resolution parameter estimation, and real-time monitoring applications. The framework is appropriate for real-time monitoring of elderly patients' health without physical contact with healthcare professionals, maintaining safety standards. The hardware includes sensors for monitoring steps, pulse oximetry, heart rate, and temperature using low-power wireless communication. In terms of parameter estimation, the embedded circuit uses high-resolution signal processing algorithms that result in an improved measure of the HR. The proposed high-resolution signal processing-based approach outperforms state-of-the-art HR estimation measurements using the photoplethysmography sensor. (shrink)

Schools have been the main context for physical activity and sedentary behavior interventions among adolescents, but there is inconsistent evidence on whether they also improve dimensions of the health−related quality of life. The aim of this study was to evaluate the effects of a school-based active lifestyle intervention on dimensions of HRQoL. A secondary aim was to verify whether sex, age, and HRQoL at baseline were moderators of the intervention effect. A cluster-randomized controlled trial was conducted at three control and (...) three intervention schools in Florianopolis, Brazil. All students from 7th to 9th grade were invited to participate. A school year intervention, designed primarily to increase PA and reduce SB, included strategies focused on teacher training on PA, SB, and nutrition, and availability of teaching materials related to these contents; environmental improvements ; and education strategies, with the availability of folders and posters regarding PA, SB, and nutrition. Participants and the research staffs were not blinded to group assignment, but a standardized evaluation protocol was applied at baseline and after the intervention using the KIDSCREEN−27 to assess HRQoL across five dimensions. Mixed linear models were performed to evaluate the effect of the Movimente intervention on the five HRQoL dimensions. Of the 921 students who answered the questionnaire at baseline, 300 and 434 completed the study in control and intervention groups, respectively. The results revealed no significant effects of the intervention on any HRQoL dimensions. A reduction of the school environment dimension was observed in both the control and intervention groups. Sensitivity analyses showed that students in the highest baseline tertiles of HRQoL in any dimension had a reduction in their respective scores from pre- to post-intervention in both school groups. In conclusion, our results demonstrated no intervention effect on HRQoL dimensions and those students with the highest levels of HRQoL at baseline on all dimensions reduced from pre to post-intervention.Clinical Trial RegistrationThe trial is registered at the Clinical Trial Registry.

The issue of what consequences to draw from the existence of non-classical logical systems has been the subject of an interesting debate across a diversity of fields. In this paper the matter of alternative logics is considered with reference to a specific belief system and its propositions :the Azande are said to maintain beliefs about witchcraft which, when expressed propositionally, appear to be inconsistent. When the Azande have been presented with such inconsistencies, they either fail to see them as such (...) or else accept them as non-problematical. Is our knowledge of logical truths a relative and culturally determined phenomenon, or is there some (transcendent) criterion that allows us to adjudicate between alternative logical systems? The authors propose an approach for resolving disputes about the status of Azande reasoning which assumes a paraconsistent framework, thus providing a new perspective on this debate. (shrink)

We investigate the higher-order modal logic , which is a variant of the system presented in our previous work. A semantics for that system, founded on the theory of quasi sets, is outlined. We show how such a semantics, motivated by the very intuitive base of Schrödinger logics, provides an alternative way to formalize some intensional concepts and features which have been used in recent discussions on the logical foundations of quantum mechanics; for example, that some terms like 'electron' have (...) no precise reference and that 'identical' particles cannot be named unambiguously. In the last section, we sketch a classical semantics for quasi set theory. (shrink)

O pesquisador americano Joseph Banks Rhine (1895 – 1980) e o psiquiatra suíço Carl Gustav Jung (1875 – 1961) foram contemporâneos, o interesse mútuo de pesquisa levou os dois autores a estabeleceram uma troca de correspondências a partir de 1934, que duraria as duas décadas seguintes. A partir desse diálogo importantes repercussões teóricas ocorreram no trabalho dos dois autores, especialmente, em relação a Jung. Em nossa metodologia analisamos as obras de Rhine e de Jung, com destaque para o impacto dos (...) experimentos sobre percepção extrassensorial (PES) sobre o trabalho de Jung de 1952, _Sincronicidade: um princípio de conexões acausais_. Apesar das controvérsias existentes sobre o conceito de sincronicidade, com alguns autores estabelecendo que PES e sincronicidade são eventos distintos, o autor suíço estabelece de forma clara três categorias ou facetas de seu conceito, duas delas incluindo a PES.

In this paper we will present the philosopher Friedrich Nietzsche’s main reflections on the scientific enterprise, its relation to the metaphysical tradition, and how the German author drew on the nineteenth century cosmological discussion to develop a worldview that ultimately endorses a dynamic and more creative form of science, whose representations and values should not be separated from human interests.

This paper is concerned with the particular problems raised by observations of phenomena outside the common course of nature for their validation as knowledge. It examines to what extent the content of the reports and, in particular, their lack of intrinsic plausibility affected the methods used in their authentication and the assessment of testimony at the Royal Society in the first half of the eighteenth century. I show that literary strategies were usually necessary but not sufficient for the validation of (...) these kinds of observations. Next, I discuss why visual representations were especially useful in establishing the singularity of the observations, but I point out that their high costs and other restrictions meant that they were not so widespread. In contrast I show that, for a long period of time, testimony was used in the majority of the reports as the true stamp of authenticity. I note, however, that the Royal Society accepted reports by authors of varied social status, level of education and occupation, and I discuss some of the factors responsible for the complexity of the handling of testimony at the Society. I argue against Shapin that in the case of reports of extraordinary phenomena, the competence of the reporter and witnesses was often more important than their social status. The increasing role of expertise in the assessment of observations at the Society become especially apparent by the middle of the eighteenth century.Author Keywords: Authentication; Competence; Monstrous births; Singular; Testimony; Royal Society of London.

Sports occupy an interesting ethical space from a pedagogic point of view, being included in physical education curricula in most Western countries. The approach of physical education to sports as vehicle for ethical education is too limited when it is restricted to their minimal functional, constitutive and regulatory goals. This essay’s aim is to argue the extent to which the ethical potential of physical education can embrace more than functional purposes, or whether that will be neglected in terms of limited (...) educational aspirations. We present data from nineteen exploratory interviews with experienced philosophy, sports and physical education researchers and teachers, from six different nations, concerning the ethical potentiality of physical education. We highlight five ethical themes: (i) the regulatory and normative structure of sports; (ii) the spirit of sports and its internal values; (iii) the right playing/doing of sports; (iv) the overcoming in sports; and (v) sports as an opportunity for a supererogatory ethics as fertile ground for future operationalization of the potential of physical education for ethical education through sports.El deporte ocupa un interesante espacio ético desde un punto de vista pedagógico, integrándose en los curricula de educación física en la mayoría de países occidentales. El planteamiento de la educación física como vehículo de la educación ética es limitado cuando restringido a sus objetivos mínimos funcionales, constitutivos y regulatorios. El objetivo de este estudio es discutir si el potencial ético de la educación física puede ir más allá de los propósitos funcionales, que considerados aisladamente constituyen un desperdicio de la experiencia pedagógica del deporte. Para conseguirlo, presentamos datos de diecinueve entrevistas exploratorias con experimentados investigadores y profesores de filosofía, deporte y educación física relacionadas con las potencialidades éticas de la educación física. La muestra incluye individuos de seis diferentes nacionalidades, cuyo trabajo demuestra preocupaciones con el tema. La argumentación resulta de cinco temáticas principales: (i) Estructura normativa y regulativa del deporte; (ii) El espírito del deporte y sus valores internos; (iii) El bien hacer deportivo; (iv) La superación deportiva; (v) El deporte como oportunidad de una ética supererogatoria como contexto fértil para la concretización del potencial ético de una educación deportiva.

The partial structures approach has two major components: a broad notion of structure (partial structure) and a weak notion of truth (quasi-truth). In this paper, we discuss the relationship between this approach and free logic. We also compare the model-theoretic analysis supplied by partial structures with the method of supervaluations, which was initially introduced as a technique to provide a semantic analysis of free logic. We then combine the three formal frameworks (partial structures, free logic and supervaluations), and apply the (...) resulting approach to accommodate semantic paradoxes. (shrink)

The debate about constructivism in physics has led to different kinds of questions that can be conventionally framed in two classes. One concerns the mathematics that is considered for the theoretical development of physics. The other is concerned with the experimental parts of physical theories. It is unnecessary to observe that the intersection between our two classes of problems is far from being empty. In this paper we will mainly deal with topics belonging to the second class. However, let us (...) briefly mention some important problems that have been debated in the framework of our first class. For instance, the following: to what extent do the undecidability and incompleteness results of classical mathematics affect fragments of physical theories, in such way as to have a “real physical meaning”? are the mathematical arguments that seem to be essential for physics justifiable in the framework of traditional mathematical constructivism?The first question has recently been investigated by Pitowski, Penrose, da Costa, Doria, Mundici, Svozil and others. As expected by most logicians, one can construct undecidable sentences whose physical meaning seems to be hardly questionable. This happens both in classical and in quantum mechanics. (shrink)

There are several conceptions of truth, such as the classical correspondence conception, the coherence conception and the pragmatic conception. The classical correspondence conception, or Aristotelian conception, received a mathematical treatment in the hands of Tarski (cf. Tarski [1935] and [1944]), which was the starting point of a great progress in logic and in mathematics. In effect, Tarski's semantic ideas, especially his semantic characterization of truth, have exerted a major influence on various disciplines, besides logic and mathematics; for instance, linguistics, the (...) philosophy of science, and the theory of knowledge. The importance of the Tarskian investigations derives, among other things, from the fact that they constitute a mathematical, formal mark to serve as a reference for the philosophical (informal) conceptions of truth. Today the philosopher knows that the classical conception can be developed and that it is free from paradoxes and other difficulties, if certain precautions are taken. We believe that is not an exaggeration if we assert that Tarski's theory should be considered as one of the greatest accomplishments of logic and mathematics of our time, an accomplishment which is also of extraordinary relevance to philosophy, as we have already remarked. In this paper we show that the pragmatic conception of truth, at least in one of its possible interpretations, has also a mathematical formulation, similar in spirit to that given by Tarski to the classical correspondence conception.

Rousseau é reconhecido como um dos grandes filósofos da nossa tradição ocidental, sobretudo pelo impacto que os seus ideais tiveram na definição da ideologia moderna de viés republicano e até mesmo liberal. Porém, apesar da defesa incansável daqueles que viriam a ser os ideais revolucionários franceses, Rousseau insiste em manter uma prática de desigualdade naturalizada, considerando as mulheres como inferiores e eternas desiguais dos homens. Mary Wollstonecraft foi a primeira a fazer a denúncia da contradição do pensamento de Rousseau, na (...) obra que viria a ser o marco de uma literatura feminista: A Vindication for the Rights of Women. Porém, até mesmo esta denúncia está circunscrita àquele horizonte que Rousseau contribuira para desenhar: o horizonte da universalidade dos direitos, das liberdades e da igualdade. Neste artigo queremos caracterizar esta contradição levando em conta contribuições recentes de críticas feministas e apontando sua relação com o projeto democrático mais vasto. (shrink)

Procuramos expor o pluralismo de leituras da obra freudiana mediante a exploração da hipótese de historicização da formação psíquica dos sujeitos, especialmente relativa ao complexo de Édipo e Supereu. Partindo da perspectiva de estudos feministas, verificamos no corpus teórico freudiano se há a possibilidade de que o avanço sócio-histórico seja um fator de modificação de concepções que, na leitura freudiana clássica, seriam lidas como imutáveis, fixas e rígidas cultural e historicamente. Madelon Sprengnether, Nancy Chodorow e Judith Butler serão retomadas para (...) criticar a leitura clássica e generalizante do complexo de Édipo enquanto “estrutural”, essencializado e substancializado. Sugerimos que, sendo uma lei hegemônica, a vivência edípica não pode ser completamente ultrapassada, mas pode ser performativamente atuada de formas desviantes de sua estrutura classicamente pensada por Freud. Nesse âmbito, a transmissão geracional é nosso enfoque primordial. Ela é debatida ao menos em três momentos complementares: na análise da filogênese, da herança arcaica e do Édipo social exposta em Totem e tabu, na herança narcísica de expectativas e ideais compreendida em Introdução ao narcisismo e na teoria da perpetuação de valores e tradições morais via identificações geracionais superegoicas que consta nas Novas Conferências sobre Psicanálise.

This paper is a critic analysis of a doctorate thesis and a master dissertation, which subjects are the samba and the afro religions in the city of São Paulo. Both consider the samba and the religion as manifestations and cultural expressions through which the black population in afro-diaspora rebuilded and reupdated memories via religiosity, rythm, dance and performan.

In his influential work, A social history of truth, Steven Shapin has argued for the central role of social status in the assessment of experimental knowledge. In his view, in seventeenth-century England, gentlemen were considered the right kind of persons to trust because of their freedom of action, codes of virtue and honour. These characteristics ensured credibility and, hence, compelled assent. However, Shapin does not put sufficient emphasis on the relevance of the testifier’s competence in the validation of knowledge. When (...) and in which circumstances did expertise become more important than social status in the accreditation of natural knowledge? [...] I argue in this paper that it is in the realm of interpretation of unusual and ambiguous anatomies that medical and, in particular, anatomical expertise assumed its most crucial role. Moreover, the medical understanding of the hermaphroditic body in the eighteenth century can be considered one of the most illustrative cases of the construction and display of anatomical expertise. In fact, several of the academic memoirs and dissertations published on hermaphrodites in the eighteenth century attempted precisely to fulfil this purpose. (shrink)

Da Costa and French explore the consequences of adopting a 'pragmatic' notion of truth in the philosophy of science. Their framework sheds new light on issues to do with belief, theory acceptance, and the realism-antirealism debate, as well as the nature of scientific models and their heuristic development.

Esta pesquisa pretende investigar sobretudo a relação entre Sociedade e Estado. A sociedade sob a perspectiva de Tocqueville enquanto corpo coletivo democrático, ou igual. A igualdade é entendida pelo autor como um “fato social”.

Já o Estado, visto pelo autor como resultado das condições da sociedade, sendo este, instituição arquitetada dentro de parâmetros democráticos de (...) igualdade e liberdade, pelo próprio povo, que se auto governa, não apenas como instituições ou órgãos degoverno.

The fact that monstrous births were not represented in independent learned publications of the eighteenth century, except for the case of hermaphrodites, does not mean that the interest in them had disappeared or that they were no more considered proper objects of inquiry. This paper focuses on the medical understanding of monstrosity at the Royal Society of London. I point to the use of monstrous births in strengthening the authority of medical practitioners and lecturers. I also show some of their (...) uses in providing new questions for the scenes of medical inquiry of the period and as crucial evidence in the understanding of regular physiological phenomena. I discuss some of the reasons why monstrous formations continued to defy an 'Enlightenment' approach to nature based on the search for order and regularity. (shrink)

We formulate Suppes predicates for various kinds of space-time: classical Euclidean, Minkowski's, and that of General Relativity. Starting with topological properties, these continua are mathematically constructed with the help of a basic algebra of events; this algebra constitutes a kind of mereology, in the sense of Lesniewski. There are several alternative, possible constructions, depending, for instance, on the use of the common field of reals or of a non-Archimedian field (with infinitesimals). Our approach was inspired by the work of Whitehead (...) (1919), though our philosophical stance is completely different from his. The structures obtained are idealized constructs underlying extant, physical space-time. (shrink)
