Resenha do livro "Dez lições sobre Kant", de Flamarion Tavares Leite.

In this paper we pursue the study of the variety of m -generalized Łukasiewicz algebras of order n which was initiated in [1]. This variety contains the variety of Łukasiewicz algebras of order n . Given , we establish an isomorphism from its congruence lattice to the lattice of Stone filters of a certain Łukasiewicz algebra of order n and for each congruence on A we find a description via the corresponding Stone filter. We characterize the principal congruences on A (...) via Stone filters. In doing so, we obtain a polynomial equation which defines the principal congruences on the algebras of . After showing that for m > 1 and n > 2, the variety of Łukasiewicz algebras of order n is a proper subvariety of , we prove that is a finitely generated discriminator variety and point out some consequences of this strong property, one of which is congruence permutability.

The concept of corporal image includes how own body, taking into account their constituent parts, as well as the feelings related the those characteristics. The entrance in academica life provokes alterations in the feeding behavior, and the exposition to the new social environment they can bring as consequence an increase in dissatisfaction. Objective: To investigate the satisfaction with the body image and eating behavior of academics at a university center. Methods: For data collection, the following instruments were used. The evaluation (...) was performed with anthropometric measurements, as size and weight measurements. In order to diagnose the nutritional status, the body mass index was used. In order to evaluate the study variables; we used the Body Checking questionnaires Questionnaire. Male Body Checking Questionnaire, Body Shape Questionnaire and EAT-26. Results: According to the Body Mass Index, the female gender had a higher rate of adequacy (70.4%), in relation to the masculine (58,9%). The EAT-26 questionnaire showed that 85% of male engineering students presented risk for Feeding Disorders, in relation to the female psychology (89.8%). Conclusion: In terms of feeding behavior, the women scored higher than men, which suggests a higher susceptibility to Feeding Disorders development in men. (shrink)

Depois de J. Gómez Caffarena, de C.Bérubé e de R. Macken, sobretudo, terem insistidonuma leitura augustinista da antropologiahenriquina, a nossa contribuição pretende antes retirar asconsequências da correcção do augustinismoque, por meio do avicenismo, Henrique de Gandlevou a cabo. Propomos uma leitura da natureza na sua especificidade metafísica, deanterioridade em relação ao universal e ao singular,tendo como efeito uma antropoteologia que éuma verdadeira mudança de rumo do augustinismocomo uma quota-parte para a Modernidade.Ilustraremos a nossa tese insistindo: nasituação histórica de Henrique, no (...) seu programametafísico-crítico, na doutrina da relação e na daindividuação. Os textos abordados serão daSumma, dos Quodlibet e da Lectura ordinaria.Finalmente, apontaremos para um horizontecontemporâneo em que a antropologia deve serrefeita na relação com a natureza. Por outraspalavras: a natureza do homem não pode passarsem aquilo que faz o homem um ser de natureza.Foi precisamente isto que Henrique de Gandesqueceu devido ao seu avicenismo, mas nãomenos ao seu augustinismo de que é fundamentalnele.

No presente estudo, discuto e sintetizo o conceito de célula vegetal de M. J. Schleiden e o conceito de animal elementar que elaboro a partir da ideia de “animal abstrato” sugerida por R. E. Grant. A elaboração e a interpretação que conduz a essa síntese é feita ampliando a ideia do desenvolvimento como um princípio regulador, proposta por E. Cassirer. Concebo tal ideia como expressão de uma racionalidade morfológica genética. O resultado geral obtido é que a célula vegetal e o (...) animal elementar são duas variações de uma mesma forma que exibe uma íntima relação estrutural-funcional, manifesta empiricamente em duas modalidades essenciais de vida, uma simples e singular e outra complexa e plural. A interação de ambas torna inteligível fenômenos básicos da vida vegetal e animal a partir de uma matriz genética comum. (shrink)

Este relato de experiência discute um eixo de um projeto de ensino, pesquisa e extensão multi e interdisciplinar sobre educação e humanização da morte. Trata-se de ações da Psicologia destinadas à saúde mental dos trabalhadores do serviço funerário da cidade de São Paulo. A intervenção dividiu-se em duas etapas: visitas aos cemitérios, para aproximação daqueles pesquisadores à realidade e às demandas desses servidores; e oficinas com técnicas de dinâmica de grupo. Estas aconteceram por cinco meses, contaram com 130 participantes — (...) motoristas, sepultadores, “veloristas”, supervisores e gestores de recursos humanos — e tiveram como facilitadoras as integrantes da graduação e da pós-graduação em Psicologia. A análise das oficinas evidenciou, da parte dos servidores, sensibilização para suas necessidades em favor da saúde mental, percepção do valor de cuidado e humanização em suas relações profissionais e pessoais. Ademais, ações como essa realçaram a relevância de frequente acolhimento psicólogico a trabalhadores de serviços funerários. (shrink)

This article presents an overview ofregulations, guidelines and societal debates ineight member states of the EC about a)embryonic and fetal tissue transplantation(EFTT), and b) the use of human embryonic stemcells (hES cells) for research into celltherapy, including `therapeutic' cloning. Thereappears to be a broad acceptance of EFTT inthese countries. In most countries guidance hasbeen developed. There is a `strong' consensusabout some of the central conditions for `goodclinical practice' regarding EFTT.International differences concern, amongstothers, some of the informed consent issuesinvolved, and the (...) questions whether anintermediary organisation is necessary, whetherthe methods of abortion may be influenced bythe possible use of EFT, and whether EFTTshould only be used for the experimentaltreatment of rare disorders. The potential useof hES cells for research into cell therapy hasgiven a new impetus to the debate about (human)embryo research. The therapeutic prospects withregard to the retrieval and research use of hEScells appear to function as a catalyst for theintroduction of less restrictive regulationsconcerning research with spare embryos, atleast in some European countries. It remains tobe seen whether the prospect of treatingpatients suffering from serious disorders withtransplants produced by therapeutic cloningwill decrease the societal and moral resistanceto allowing the generation of embryos for`instrumental' use.

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.

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

The Letter from Pero Vaz de Caminha to the King of Portugal, Manuel I, is a unique document because its account of first contact with a people unknown in Europe up to that time may be regarded as evidence of the anthropological impossibility of a neutral gaze. This is an asymmetric testimony, as we do not possess (for obvious reasons) the Amerindian counterpart of European discourse. Although the letter’s author is someone who fully assumes the objectivity claim, we must not (...) neglect the rhetorical framework of this assumption. Hence the need for textual analysis that seeks to somehow discern the boundaries between fiction and reality. It is not as an ethnographic document, indeed, that we should value the Letter. In fact, it is necessary to recognize that this is a beautiful piece of literature whose architectural weave owes everything to the classical mechanisms of Rhetoric. (shrink)

This work aims to consider philosophically the issue of the method in philosophical practices with children. It analyzes some influences received by the creators of Philosophy for Children, Matthew Lipman and Ann Margaret Sharp, like the pragmatism of J. Dewey. It describes the meanings of three similar expressions in Lipman's work: methodical, methodological and method. It offers some criticisms of method: Hans-Georg Gadamer, but especially Henri Bergson and Gilles Deleuze. Finally, he questions the need of a method for doing philosophy (...) with children or, more broadly, for thinking childishly in education. -/- Este trabajo tiene como objetivo pensar filosóficamente el tema del método en las prácticas filosóficas con niñas y niños.

O objetivo deste artigo é analisar a ética do cuidado de enfermagem no tratamento de pacientes oncológicos. Optou-se pela pesquisa bibliográfica de abordagem qualitativa cuja metodologia foi dividida em etapas. Na primeira etapa, foi realizado um levantamento de artigos publicados, no período de 2000 a 2009, em periódicos do Scielo, utilizando os descritores: saúde/doença, enfermagem, ética do cuidado e oncologia. Esse levantamento culminou com a seleção de 28 artigos, 21 dos quais foram eleitos posteriormente para leitura aprofundada, assim como para (...) utilização no estudo. Na segunda etapa, foram explorados dados do campo, com a transcrição e análise de depoimentos de profissionais da enfermagem sobre a concepção de cuidado bem como de dados sobre pacientes oncológicos, acompanhados no período de 2007 e 2008. A pesquisa e suas exigências protocolares, sob o número CAAE - 0147.0.213.000-10, foi aprovada pelo Comitê de Ética da PUC Minas em 31 de agosto de 2010. O referencial teórico foi composto por autores que discutem o cuidado na perspectiva filosófica e teológica - Boff (2001, 2005 e 2006), Efken (2005) - e autores da área da saúde oncológica, entre eles, Carvalho et al. (2002), Popim & Boemer (2005), Visentin, Labronici & Lenardt (2007) e Araújo et al. (2009). Os resultados evidenciaram o cuidado na enfermagem como princípio ético essencial, assim como a necessidade de investimentos em políticas públicas de saúde no Brasil, que efetivem o trabalho de prevenção, educação e cura do câncer. Palavras-Chave: Saúde/Doença; Enfermagem; Ética do cuidado; Oncologia.The objective of this article is to analyze the nursing care in the treatment of oncology patients. We have opted for bibliographical research of qualitative nature, a methodology divided into stages. In the first stage we gathered articles in a publication called Scielo from 2000 to 2009, which described: health/illness, nursing, ethics of care, and oncology. Through this process the selection of twenty-eight articles was accomplished, however only twenty-one articles were utilized in the production of this study. In the second stage field data were explored, we transcribed and analyzed the statements of nursing professionals on the conception of care and on oncology patients overseen by them in the period of 2007 to 2008. The research protocol and its requirements under the number CAAE - 0147.0.213.000-10, was approved by the Ethics Committee of PUC Minas on August 31, 2010. The theoretical support was provided by authors who discuss care in a philosophical and theological perspective: Boff (2001, 2005, and 2006), Efken (2005); and authors in the field of healthcare, among them Popim & Boemer (2005), Silva et. al , (2005), Souza et al. (2005), Visentin, et al. (2007), and Araújo, et. al. (2008). The results demonstrated the care in nursing as an essential ethical principal, as much as the necessity of investment in public health policies in Brazil, for the effective promotion of cancer prevention, education and cure. Key words : Health/Illness; Nursing; Ethics of Care; Oncology. (shrink)

The Afro-Brazilian connections between the coast of West Africa and Brazil date back to the transatlantic slave trade and the Muslim uprising in Bahia in 1933. After this major rebellion, many former slaves returned to West Africa bearing a large Brazilian cultural imprint consisting of architectural skills, culinary traditions, and song and dance. They also brought back Brazilian names and cosmopolitan outlooks. From Africa, enslaved Africans carried with them to Brazil philosophical and cosmological outlooks and indeed, culture generally. Some of (...) these cross-fertilizations are what are interrogated in this intellectual and cultural exchange. (shrink)

O debate entre J. Searle e D. Dennett acerca da possibilidade técnica de uma Inteligência artificial gira em torno de uma única questão: estados mentais expressam algo intrínseco, privado e subjetivo, experimentado em primeira-pessoa ou não passam de entidades obscurantistas, frutos da ignorância e, em princípio, reduzíveis à objetividade científica da neurociência? Searle defende a primeira tese, enquanto Dennett argumenta pela segunda. O texto expõe a posição de Dennett, a crítica de Searle e se direciona para uma nova solução, que (...) defende um monismo integral, no qual mente e cérebro podem ser vistos como duas dimensões de uma mesma realidade. Nesse sentido, o projeto de Inteligência artifical precisará revisar o conceito de “físico” se quiser avançar em suas pretenções, incluindo nele conceitos hoje antagônicos como intencionalidade, liberdade e subjetividade.: The debate between J. Searle and D. Dennett about the technical possibility of an artificial intelligence revolves around a single issue: mental states express something intrinsic, private and subjective, experienced in first-person or are merely obscurantist entities, results from ignorance and, in principle, reducible to scientific objectivity of neuroscience? Searle argues for the first position, while Dennett argues for the second. The text exposes the position of Dennett, the criticism of Searle and is directed to a new solution, which advocates an integral monism, in which mind and brain can be seen as two dimensions of the same reality. In this sense, the project of artificial intelligence need to review the concept of "physical" if it wants to advance its claims, including today antagonistic concepts such as intentionality, freedom and subjectivity. Keywords: physicalism, technique, artificial intelligence, John Searle, Daniel Dennett. (shrink)

Niche construction theory highlights the active role of organisms in modifying their environment. A subset of these modifications is the developmental niche, which concerns ecological, epistemic, social and symbolic legacies inherited by organisms as resources that scaffold their developmental processes. Since in this theory development is a situated process that takes place in a culturally structured environment, we may reasonably ask if implicit cultural biases may, in some cases, be responsible for maladaptive developmental niches. In this paper we wish to (...) argue for an affirmative answer. In order to do so, we first propose to conceptualize implicit bias as embodied perceptual habits, and then proceed to show that these habits are at least partially responsible for maladaptive developmental niches of children with Down syndrome and autism. With this framework we thus hope to bring together two fields of research that haven’t been explicitly connected: implicit bias and niche construction theory. Linking these two theories may bring benefits both to implicit bias researchers, who can extend this concept to characterize other sets of processes as biased, as well as to niche construction theorists, who will have a useful theoretical tool to diagnose maladaptive features of niches brought about by sociocultural biases.

On the one hand, much has been written on Theodosius Dobzhansky’s central role in the development of the field of population genetics and modern evolutionary theory, as well as on his sociopolitical worldview in the middle of the Twentieth Century. On the other hand, much has also been written on Dobzhansky’s role in the institutionalization of genetics in Brazil, where he spent a considerable amount of time. Unfortunately, these literatures developed without any points of intersection or cross-reference. This article places (...) Dobzhansky’s work in Brazil in the broader contexts of the science and politics of its historical period. (shrink)

Il est couramment admis qu’il existe une corrélation, sinon un rapport de cause à effet, entre la fréquence lexicale d’une dérivation et sa productivité, mesurée à l’aune de sa force d’attraction analogique.

In this paper I claim that perceptual discriminatory skills rely on a suitable type of environment as an enabling condition for their exercise. This is because of the constitutive connection between environment and perceptual discriminatory skills, inasmuch as such connection is construed from an ecological approach. The exercise of a discriminatory skill yields knowledge of affordances of objects, properties, or events in the surrounding environment. This is practical knowledge in the first-person perspective. An organism learns to perceive an object by (...) becoming sensitized to its affordances. I call this position ecological disjunctivism. A corollary of this position is that a case of perception and its corresponding case of hallucination—which is similar to the former only in some respects—are different in nature. I show then how the distinguishability problem is addressed by ecological disjunctivism. (shrink)

ABSTRACTAstrologers have exercised self-censorship throughout the centuries in order to fend off criticism. This was largely for religious reasons, but social, political, and ethical motivations also have to be taken into account. This paper explores the main reasons that led astrologers to increase censorship in their writings in the decades that preceded the Church’s regulations and offers some examples of this self-imposed restraint in astrological judgements.

How can we explain our capacity to think about particulars in our external environment? Many philosophers have answered this question in terms of a sophisticated conception of space and time and the movement of objects therein. A more recent reaction against this view sought to explain this capacity solely in terms of perceptual mechanisms of object individuation. Neither explanation remains fully satisfactory. This book argues for a more desirable middle ground in terms of a pragmatist approach to demonstrative thought, where (...) this capacity is explained through graded practical knowledge of objects. This view allows us to do justice to important insights put forward by both positions criticized in the book, while avoiding their potential shortcomings. It also paves the way to a more pragmatist approach to the theory of mental representation, where the notion of practical knowledge is allowed to play a central role in our cognitive life. Finally, it shows how practical knowledge may be firmly rooted in neurobiological processes and mechanisms that conform to what the empirical sciences tell us about the mind. (shrink)

Através deste artigo científico pretende-se expor as contribuições de Linda Zagzebski para a teoria da epistemologia das virtudes contemporânea, evidenciando sua inspiração na teoria das virtudes de Aristóteles. A inovação trazida por Zagzebski é a proposta de indistinção entre virtudes morais e virtudes intelectuais. Para a autora, as virtudes intelectuais são um subconjunto das virtudes morais, e assim merecem avaliação conjunta com estas. Por fim, argumenta-se que essa interpretação não implica em um reducionismo das virtudes intelectuais e que pode servir (...) para inspirar uma renovação nas discussões filosóficas contemporâneas.

Cognitive sciences as an interdisciplinary field, involving scientific disciplines (such as computer science, linguistics, psychology, neuroscience, economics, etc.), philosophical disciplines (philosophy of language, philosophy of mind, analytic philosophy, etc.) and engineering (notably knowledge engineering), have a vast theoretical and practical content, some even conflicting. In this interdisciplinary context and on computational modeling, ontologies play a crucial role in communication between disciplines and also in a process of innovation of theories, models and experiments in cognitive sciences. We propose a model for (...) this process here. An ontological commitment is advocated as the framework of a scientific realism, which leads computational modeling to search for more realistic models, for a complex systems perspective of nature and cognition. In that way multiagent modeling of complex systems has been fulfilling an important role. (shrink)

Ao longo da Metafísica e dos tratados de filosofia natural, Aristóteles toma os organismos vivos como os exemplos paradigmáticos de οὐσίαι (substâncias) naturais. No entanto, além dos organismos vivos, em certas passagens o filósofo menciona, também, as partes dos viventes e os elementos como exemplos de substâncias. Contudo, em outras passagens, Aristóteles parece considerar que as partes dos seres vivos e os corpos elementares não representariam, genuinamente ou propriamente, entidades substanciais. Por outro lado, em nenhum momento, o filósofo parece indicar (...) expressamente os corpos homogêneos inanimados (metais e minerais), tratados no livro IV dos Meteorológicos, enquanto tipos de seres substanciais. Neste artigo, pretendo, então, examinar se as partes do vivente e os elementos poderiam, de fato, contar ou não como exemplares genuínos de substâncias naturais; e em que medida os corpos homogêneos inanimados, a despeito de não serem explicitamente citados na condição de entes substanciais, poderiam, a partir do exame de suas naturezas composicionais, sustentarem, de uma maneira estrita, o título de οὐσίαι naturais.
