The scientific community has debated the importance of “return” activities after ethnobiological studies. This issue has provoked debate because it touches on the ethics of research and the relationships with the people involved in these studies. This case study aimed to investigate community perception of an ethnobotany research project that was carried out in the semi-arid region of northeastern Brazil. Furthermore, we reported how the residents of this rural community felt about participating in the activities of “return” that arose from (...) the projects. Our findings demonstrate that “return” activities should be planned from the design phase of the research until its closure as a lifelong process that allows the communities involved to gradually take ownership of the information and actions that are being generated. Similarly, we argue that such activities must be negotiated with the people of the community so that they have decision-making power and autonomy to decide what is most relevant to their lives.

O manuscrito clandestino Jordanus Brunus redivivus ou Traité des erreurs populaires foi publicado em 1771, não trazendo indicação alguma de sua autoria. Entretanto, a despeito do anonimato da obra, ela tornou-se um dos textos mais famosos dentre a filosofia clandestina do século XVIII, aludindo a um filósofo que foi uma das maiores vítimas da superstição e do fanatismo de sua época: Giordano Bruno. O título do escrito é uma espécie de homenagem ao pensador italiano, mas não há no decorrer da (...) obra uma menção sequer que comprove que o autor anônimo tenha lido uma linha de suas obras, mesmo que seja considerado o elo filosófico de união entre o brunismo da primeira metade do século XVII e o da segunda metade do século XVIII. É em um encadeamento de ideias progressivo no Jordanus Brunus que nos permite encontrar o fio condutor das reflexões do autor: a sua formulação do ateísmo caracteriza-se por sua abordagem não dogmática, dissimulada, preparando o solo para o racionalismo ateu que estaria por vir. O presente artigo limitar-se-á à terceira e quarta partes do manuscrito, nas quais o autor anônimo vai tratar diretamente da questão da existência de deus e fazer diversas objeções às provas de sua existência.

Circunscrevendo o âmbito no qual o ateísmo pode ser compreendido, a saber, na esfera dos costumes, convenções religiosas, políticas e teológicas, e até mesmo no campo dos temperamentos e caracteres, desde os Pensées diverses sur la comète até a Continuation des Pensées sur la comète e a Réponse aux quéstions d’un Provincial Bayle erige, fundamenta e radicaliza o vínculo entre ateísmo e virtude, entendendo aqui ateísmo sob um enfoque de caráter prático, ou seja, em relação à atitude daqueles que vivem (...) como se um deus não existisse, minimizando o valor de sua eficácia sobre a conduta humana. Porém, tal postura não é menos dotada de virtude, uma vez que se entenda tal termo como uma perpétua disposição para cumprir determinados atos morais e tendo como objeto os atos da vida prática, como por exemplo, justiça, honestidade, coragem, amizade, entre outros.

Olympe de Gouges publica as Réflexions sur les hommes nègres no ano de 1788. Com ideias abolicionistas, a autora aborda a condição dos escravos negros no Século das Luzes, em um contexto de profusão do ideário dos progressos da razão em todos os campos do saber. Ela evidencia, porém, que os ideais de liberdade, igualdade e fraternidade ainda estavam bastante aquém de serem praticados ao pé da letra.

Em um pequeno escrito intitulado Apologie de l’ennui et des ennuyeux, Holbach, sob uma apologia, repudia a figura do ennuyeux. O retrato dos costumes traçado pelo Barão é acompanhado de uma crítica filosófica que remonta às causas originais tanto da propagação como da universalidade do tédio. Tal reflexão o Barão já empreendera em La Moral Universelle, o que permite fazer uma leitura da Apologie como uma crítica invertida, por meio de uma condenação contundente do tédio, este entendido como uma permanente (...) insatisfação da natureza humana.

Resumo: A superstição é definida por Bayle, em diversos momentos e diversas obras do filósofo francês, como: a) algo característico da corrupção natural humana; b) a prova da facilidade do homem em se ater às mais diversas crendices, logo, estando sujeito não só a uma, mas a todo tipo de superstições; c) o fenômeno que se instaurou e se disseminou na sociedade, perseguindo a todos e gerando ilusões por toda parte, através de presságios, profecias, prodígios, e sinais. Nesse quadro de (...) diversas e intangíveis absurdidades, a superstição ganha forma, indo para além dos domínios da razão e, assim, Bayle, em seus escritos, torna manifesta a oposição entre a filosofia e a ignorância supersticiosa, entre o entendimento e a imaginação e entre as explicações científicas e os relatos fantásticos.: Superstition is defined by Bayle at various times and in various works as: a) something characteristic of natural human corruption; b) proof of the ease of man in adhering to the most diverse beliefs, being subject not only to one but to all kinds of superstitions; c) a phenomenon which arose and spread in society, following everyone and creating illusions everywhere by means of omens, prophecies, miracles, and signs. In this context of the diverse and intangible absurdities in which superstition takes shape, going beyond the realms of reason, Bayle in his writings makes manifest the opposition between philosophy and superstitious ignorance, between understanding and imagination, and between scientific explanations and fantastic tales.

Em seu Système de la nature, Holbach afirma que algumas ideias que o homem engendra dentro de si são derivadas de uma oscilação dos humores que o impede de entrever quais as razões de atribuir um caráter sacro a certas palavras ou opiniões. Nesse sentido, as paixões, longe de serem romantizadas e levarem vantagem em relação à reta razão justamente por serem menos frias e mais lúdicas, sob a pena do barão ganham uma imagem negativa, definidas como verdadeiros obstáculos ao (...) homem que pretende entender os princípios, o curso e as leis da natureza dispensando o recurso a instâncias ou entidades sobrenaturais criadas pela imaginação, pela inconstância dos humores ou pela linguagem.

Quando Bayle reflete sobre a possibilidade de um ateísmo especulativo, ele argumenta acuradamente a respeito, mostra que o ateísmo pode dar sua contribuição a diversas discussões de ordem teórica, como a questão do livre-arbítrio, da providência e do mal, por exemplo. Se o filósofo de Carla se pronuncia a favor do ateísmo especulativo, ele vai mais além e afirma uma moral natural, a qual, apoiada em princípios comuns a todos os homens, permite vislumbrar e dar solidez a sua tese fundamental (...) desde os Pensées diverses sur la comète: a associação entre ateísmo e virtude. Dessa forma, Bayle expõe e analisa os diversos argumentos e pontos de vista a respeito do estatuto filosófico do ateísmo especulativo. (shrink)

Há uma espécie de drama de consciência no interior do pensamento iluminista em relaçáo à Revoluçáo Francesa: de um lado, aceita, de bom grado, fazer da queda do Antigo Regime um de seus mais belos e significativos frutos; de outro, recusa, por vezes enojado, os meios violentos utilizados para tanto e náo aceita, ou custa a aceitar, filiaçáo ideológica com eles. Esta violência “excessiva” seria exclusivamente obra da massa, segundo o elitismo iluminista.

ContextPeople with mental disorders can acquire long-term disabilities, which could impair their functioning and quality of life (QoL), requiring permanent care and social support. Systematic data on QoL and functioning, which could support a better management of these people, were not available.ObjectiveTo analyze the QoL, level of functioning and their association with sociodemographic and clinical factors of people with mental disorders who underwent deinstitutionalization using assisted living facilities.MethodsA Cross-sectional study was conducted between July 2018 and July 2019, through interviews using (...) the World Health Organization Quality of Life (WHOQOL-BREF) to determine the QoL scores, and the World Health Organization Disability Assessment Schedule (WHODAS 2.0) to determine the level of functioning. All adults (≥18 years old) with mental disorders, who underwent deinstitutionalization, users of assisted living facilities and assisted by the Psychosocial Assistance Centers III, in a city in the state of São Paulo, Brazil, were selected. For statistical analysis of the associated factors, Student’st-test was used for dichotomous variables and ANOVA for polynomial variables. Pearson correlation coefficient was used to measure the association between QoL and functioning scores.ResultsOut of 359 people who underwent deinstitutionalization with mental disorders, 147 met the eligibility criteria. The mean total score for the WHOQOL-BREF was 66.5 ± 13.4 and the mean score for WHODAS 2.0 was 10.4 ± 7.6. An association was found between people who were studying (n= 65.8; 95%CI, 63.5–68.1vs. n= 73.9; 95%CI, 67.5–80.3;p= 0.04) and better WHOQOL-BREF QoL scores or WHODAS 2.0 levels of functioning (n= 10.9; 95%CI, 9.6–12.2vs. n= 5.1; 95%CI, 2.5–7.7;p= 0.01). A weak negative correlation (r= 0.41) emerged between higher QoL scores and functioning improvement.ConclusionThis study indicates that the QoL of the sample is associated by their functioning levels, which, in turn, may reflect on their social interactions. Public policies that favor interventions increasing socialization of this population can result in better health outcomes. The QoL and functioning scores provide valuable insights to develop public policies more suited to this population profile. (shrink)

To investigate the effects of two different modes of physical activity on body composition, physical fitness, cardiometabolic risk, and psychological responses in female adolescents participating in a multi-disciplinary program. The 12-week randomized intervention included 25-adolescents with overweight divided into two groups: sports practice-SPG and functional training-FTG. The SPG intervention was divided into three sports: basketball, handball, and futsal. SPG participants performed one sport 3-times/week, over the course of 1 month. The FTG performed concurrent exercises 3-times/week. This study was registered in (...) Clinical Trials Registry Platform under number: RBR-45ywtg and registered in Local Ethics Committee number: 2,505.200/2018. The intensity of physical exercises-PE was matched between groups by the rating of perceived exertion. The primary outcome was body composition, and secondary outcomes were physical fitness, cardiometabolic risk, and psychological responses. There was a significant time-effect for body mass, body mass index, and low-density lipoprotein, all being reduced. There were increases over time for musculoskeletal mass, aerobic fitness, and high-density lipoprotein. There was a group time interaction with body fat percentage being lower post-intervention in the SPG. No significant differences were observed for the other variables. Both physical activity models were effective in improving a subset of obesity-related health parameters. The findings should be extended by further investigation using more sophisticated measures of energy expenditure.Clinical Trial Registration:https://ensaiosclinicos.gov.br/, identifier: RBR-45ywtg.

This chapter argues that the Covid-19 pandemic has exposed the limits of the mainstream individualistic notion of resilience and, in light of these limits, it advances a new, relational notion of the concept of resilience that contributes to the individuals’ well-being and takes into consideration the role of systemic inequality. The first half of the paper argues that the individualistic notion is flawed in two ways: i) it can foster ill-being because it is cognitively taxing, and ii) it discounts systemic (...) inequality because it transfers the responsibility of any achievement and failure onto the single individual without regard for conditions of oppression. The second half of the paper reconceptualizes the concept of resilience as a relational notion that takes into account structural support as well as conditions of oppression and marginalization. According to this latter notion of resilience, the chapter argues that oppression, lack of material conditions, or lack of structural support are elements that can impact the appropriateness of calls to be resilient. A relational notion of resilience fosters well-being because it puts the collective community at the center (instead of the individual) and it takes into consideration material conditions and structural injustices.

Introduction: The actions taken by the government to deal with the consequences of the coronavirus diseases 2019 pandemic caused different levels of restriction on the mobility of the population. The need to continue offering physical exercise to individuals after stroke became an emergency. However, these individuals may have barriers to adhere to the programs delivered remotely. There is a lack of evidence related to adherence, attendance, safety, and satisfaction of remote exercise programs for this population.Objective: The aim was to evaluate (...) adherence and barriers to attend a remote physical exercise program for individuals after stroke. We aimed to identify adherence and attendance rate of the remote physical exercise program ; to identify the safety of a remote physical exercise program ; and to identify the overall experience to participate in a remote program.Materials and methods: This is a longitudinal study, including 36 stroke survivors who already attended a face-to-face physical exercise program prior to the COVID-19 pandemic. The remote physical exercise program included sessions for 2 days/week for a duration of 22 weeks, with a total of 44 sessions, which were delivered asynchrony via recorded video sessions. As outcome measures, we performed two questionnaires to identify attendance, barriers, safety, and overall experience related to the program.Results: The adherence rate was 86. The attendance rate was 19, with a total of 8 sessions. The main barriers for lower attendance rate were as follows: lack of motor skills and physical fitness to workout in 80 reports, followed by no exercise companion in 44 reports. The remote physical program has been shown to be safe, and the overall experience was positive from the perspectives of the participants and the family members.Conclusion: Although the adherence rate was high, the attendance rate was low on the remote physical exercise program. The main barriers to attending the program remotely reflect the need of tailoring individually an asynchrony mode of delivering the sessions to individuals after stroke. Our results also indicate how the COVID-19 impacted the health conditions of stroke survivors. The program was safe, and the overall experience indicated a change in the mental, physical, and social health of individuals after stroke and their family members. (shrink)

Several countries maintain universal health coverage, which implies responsibility to organize delivery formats of healthcare services and products for citizens.

Our data set for this investigation was comprised of posts including the hashtag #vacina (vaccine), extracted using the Python TikTokAPI library. Emotions were identified and classified using standardized descriptors from the Human-Machine Interaction Network on Emotion (HUMAINE) and the Core Affect Model. Given the diversity of content on (...) TikTok, videos with emotional content were also separated into categories. Results revealed a prevalence of positive emotions such as contentment, enthusiasm, and interest regarding the vaccines, especially in videos of a personal and informative character. Negative emotions, such as doubt and disapproval, were associated with contextual and strategic factors, with significant expression in humorous and infotainment publications. (shrink)

This article investigates the existence of an original Brazilian legal culture. It parts from a critical examination of the key moments in the history of Brazil through the accounts of its most important scholars, such as Caio Prado Júnior, Darcy Ribeiro, Sérgio Buarque de Holanda, Wilson Martins, Oliveira Viana, Roberto Damatta, José Murilo de Carvalho, among others. It identifies in the Brazilian legal culture something one might call tradition of exception, which can be found in many of its most prominent (...) aspects, such as the persistent denial of any general or abstract regulatory standards, the uncritical introduction of foreign doctrines and legal patterns, the maintenance of aristocratic traditions in social life and the historical disregard of the Brazilian people as political subject. The article also offers a reflection on the problems and potentials of the current historic moment, in which for the first time Brazilians face the possibility of a genuine cultural emancipation.

In this chapter we use methods of corpus linguistics to investigate the ways in which mathematicians describe their work as explanatory in their research papers. We analyse use of the words explain/explanation (and various related words and expressions) in a large corpus of texts containing research papers in mathematics and in physical sciences, comparing this with their use in corpora of general, day-to-day English. We find that although mathematicians do use this family of words, such use is considerably less prevalent (...) in mathematics papers than in physics papers or in general English. Furthermore, we find that the proportion with which mathematicians use expressions related to ‘explaining why’ and ‘explaining how’ is significantly different to the equivalent proportion in physics and in general English. We discuss possible accounts for these differences. (shrink)

O ficcionalismo, geralmente classificado como um tipo de nominalismo, apresenta como perspectiva precípua a tese de que os entes matemáticos são ficções. Para o ficcionalista, o discurso matemático é desprovido de conteúdo. Hartry Field, que é o principal defensor dessa concepção ontológica da matemática, contesta, em Science Without Numbers, a utilização de entes matemáticos na redação de teorias da física, alegando que a defesa mais plausível do realismo ontológico matemático é o argumento da indispensabilidade de Quine-Putnam. O ficcionalismo defendido por (...) Field nos permite, de acordo com Shapiro, classificá-lo no grupo filosofia-primeiro, ou seja, entre os filósofos que defendem que a filosofia deve ser responsável por legislar a respeito da prática matemática. Dessa forma, podemos considerar Field um revisionista epistemológico. Como se sabe, a dependência da ciência moderna em relação ao discurso matemático coloca a tese ficcionalista em xeque. Ainda assim, se partirmos dos pressupostos filosóficos da vertente formalista da filosofia da matemática, que concebe a matemática como constituída de um conjunto de regras sem significado que podem ser manipuladas de maneira puramente sintática, poderemos traçar importantes analogias entre matemática e ficção, tal como também entre metamatemática e metaficção. Para um formalista simpático à tese ficcionalista, o estatuto ontológico da matemática é semelhante ao das regras de um jogo de xadrez. (shrink)

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are given. Specifically, (...) a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

Despite being fairly powerful, finite non-deterministic matrices are unable to characterize some logics of formal inconsistency, such as those found between mbCcl and Cila. In order to overcome this limitation, we propose here restricted non-deterministic matrices (in short, RNmatrices), which are non-deterministic algebras together with a subset of the set of valuations. This allows us to characterize not only mbCcl and Cila (which is equivalent, up to language, to da Costa's logic C_1) but the whole hierarchy of da Costa's calculi (...) C_n. This produces a novel decision procedure for these logics. Moreover, we show that the RNmatrix semantics proposed here induces naturally a labelled tableau system for each C_n, which constitutes another decision procedure for these logics. This new semantics allows us to conceive da Costa's hierarchy of C-systems as a family of (non deterministically) (n+2)-valued logics, where n is the number of "inconsistently true" truth-values and 2 is the number of "classical" or "consistent" truth-values, for every C_n.

The logics of formal inconsistency (LFIs, for short) are paraconsistent logics (that is, logics containing contradictory but non-trivial theories) having a consistency connective which allows to recover the ex falso quodlibet principle in a controlled way. The aim of this paper is considering a novel semantical approach to first-order LFIs based on Tarskian structures defined over swap structures, a special class of multialgebras. The proposed semantical framework generalizes previous aproaches to quantified LFIs presented in the literature. The case of QmbC, (...) the simpler quantified LFI expanding classical logic, will be analyzed in detail. An axiomatic extension of QmbC called QLFI1o is also studied, which is equivalent to the quantified version of da Costa and D'Ottaviano 3-valued logic J3. The semantical structures for this logic turn out to be Tarkian structures based on twist structures. The expansion of QmbC and QLFI1o with a standard equality predicate is also considered. (shrink)
