Está bem estabelecido que a moderna noção de ser humano está firmemente ancorada no conceito de evolução natural, no que diz respeito à sua origem biológica, e no conceito de cultura, no que diz respeito à sua condição existencial e sua multiplicidade de modos de vida. Este artigo discute a relação entre o paradigma evolucionista nas ciências naturais e o pensamento antropológico moderno analisando as raízes de alguns mal-entendidos entre as duas tradições intelectuais. Notadamente, o embaralhamento entre os legados da (...) obra do naturalista Charles Darwin e do filósofo Herbert Spencer para a escola de pensamento conhecida como evolucionismo social, hegemônica entre a década de 1870 e a I Guerra Mundial no contexto antropológico. A partir da crítica dirigida aos autores desta escola por Franz Boas, fundador da antropologia cultural norte-americana, o artigo demonstra que o conceito evolutivo empregado por evolucionistas sociais como Edward B. Tylor e Lewis H. Morgan remete mais às concepções teleológicas e dedutivas de Spencer da evolução como uma lei, que às formulações indutivas e não-teleológicas de Darwin da seleção natural como um mecanismo. Por fim, o artigo salienta afinidades entre a teoria da cultura de Boas e a visão de mundo darwiniana maiores do poderia se supor, dentre as quais: uma perspectiva mais retroditiva que preditiva sobre as origens da variação natural e cultural; a substituição da ortogênese determinada pela filogênese indeterminada; e da crença no progresso absoluto e no excepcionalismo humano pelo relativismo com respeito ao lugar da humanidade e suas formas de vida cultural no mundo.

Tenho escrito muitos prefácios para livros, mas nenhum me deu tanto prazer em tempos recentes quanto o livro de Caetano Costa. Estou a falar de quê? De um livro de teoria jurídica, de um livro de sociologia do direito, de um romance que tem como principais personagens dois juízes? Estou a falar de tudo isso e nessa complexidade reside o fascínio desta obra, cuja leitura eu recomendo vivamente a todos e a todas.

Resumo: O fenômeno da relatividade conceitual ocorre, segundo Putnam, quando uma descrição verdadeira a partir de uma perspectiva torna-se incompatível com uma descrição equivalente verdadeira a partir de outra perspectiva. Nosso objetivo será examinar em que sentido é possível conciliar a tese da relatividade conceitual com o princípio realista de que o mundo consiste numa totalidade fixa de objetos que não dependem de nossos pensamentos ou sistemas categoriais. Para o metafísico realista, ainda que nossas conceituações do mundo tenham um caráter (...) relativo e perspectivo, daí não se segue que o próprio mundo seja igualmente dependente de nossos esquemas conceituais.: the phenomenon of conceptual relativity turns on the fact that the descriptions of the world can change truth-value upon passing from one correct theory to another correct theory. In this sense, can metaphysical realism - the perspective that the world consists of some fixed totality of mind-independent objects - recognize the phenomenon of conceptual relativity -/- Abstract: The phenomenon of conceptual relativity turns on the fact that the descriptions of the world can change truth-value upon passing from one correct theory to another correct theory.

Resumo: Peirce toma como verdadeiras as conclusões estáveis obtidas, a longo prazo, pela aplicação sistemática do método de pesquisa científica. Como notou Hacking, o realismo interno de Putnam duplica o processo de levar ao limite, pois acrescenta que também as normas ou padrões de racionalidade são produtos históricos que podem evoluir com o tempo e postula, no limite da investigação, uma situação epistemicamente ideal. Nossa intenção é examinar criticamente a proposta de Putnam de caracterizar a verdade como idealização da aceitabilidade (...) racional.: Peirce thinks that the truths are the stable conclusions reached by scientific inquiry continued long enough. As Hacking remarked, in Putnam's internal realism there is a double limiting process because the methods of inquiry can themselves grow. This paper aims at discussing Putnam's view that truth is an idealization of rational acceptability. (shrink)

Margaret Archer plays a leading role in the sociological analysis of the relation between structure and agency, and particularly in the study of reflexivity. The main aim of this article is to discuss her approach, focusing on the main contributions and limitations of Archer’s theory of reflexivity. It is argued that even though her research is a pioneering one, proposing an operationalization of the concept of reflexivity in view of its empirical implementation, it also minimizes crucial social factors and the (...) dimensions necessary for a more complex and multi-dimensional study of the concept, such as social origins, family socialization, processes of internalization of exteriority, the role of other structure–agency mediation mechanisms and the persistence of social reproduction.

The canonical view of a 3‐domain (3D) tree of life was recently challenged by the discovery of Asgardarchaeota encoding eukaryote signature proteins (ESPs), which were treated as missing links of a 2‐domain (2D) tree. Here we revisit the debate. We discuss methodological limitations of building trees with alignment‐dependent approaches, which often fail to satisfactorily address the problem of ‘‘gaps.’’ In addition, most phylogenies are reconstructed unrooted, neglecting the power of direct rooting methods. Alignment‐free methodologies lift most difficulties but require employing (...) realistic evolutionary models. We argue that the discoveries of Asgards and ESPs, by themselves, do not rule out the 3D tree, which is strongly supported by comparative and evolutionary genomic analyses and vast genomic and biochemical superkingdom distinctions. Given uncertainties of retrodiction and interpretation difficulties, we conclude that the 3D view has not been falsified but instead has been strengthened by genomic analyses. In turn, the objections to the 2D model have not been lifted. The debate remains open. Also see the video abstract here: https://youtu.be/-6TBN0bubI8. (shrink)

O método axiomático é considerado uma das principais ferramentas para a sistematização do conhecimento. Inaugurado na Grécia antiga, o método axiomático passou por grandes mudanças ao longo da história. Este artigo busca estabelecer as fases de evolução da abordagem axiomática. Divide-se a axiomática em três categorias: concreta, abstrata ou formal. Divide-se em a axiomática três categorias: concreta, abstrata ou formal. Em um segundo momento, o artigo aproxima a utilização do método axiomático na física quântica, através da apresentação informal da axiomática (...) de uma lógica não-reflexiva. Batizada pelo filósofo e lógico brasileiro Newton da Costa como Lógica de Schrödinger, sua motivação encontra-se na posição teórica perante o status ontológico das entidades postuladas pela física quântica, denominada Received View.

With the advance of COVID-19 in the world, it is necessary to reflect on how the different realities influence the processes of advancement and containment of the impacts generated from the pandemic. Guinea-Bissau, being a country that has been recording military coups since 1980, has become a vulnerable country in all respects. The vulnerability of the country is so great that structural reform has not been possible in the state apparatus since its independence from the yoke Portuguese in 1973; in (...) this way this Democratic Republic is economically dependent on its international partners even for the implementation of its general state budget. With cashew nuts as the main and almost only product that moves the economy, the country has seen the needs and demands of the population worsen with the arrival of the new coronavirus, thus having the increase in the expenses of families in acquiring food and hygiene products to cope with the disease, in view of the economic weakness of its citizens. This article aims to analyze the sociopolitical processes that influence the management of the pandemic in Guinea Bissau. Its work methodology is a review of literature obtained through scientific journals and portals. It was observed in this path the need for training of new professional staff and greater investment in the structure, both economic and health, so that we can manage moments of crisis as faced. This will only be possible through the alignment between state and civil society around a participatory and supportive development project. (shrink)

A new split β‐lactamase assay promises experimental testing of the interplay of protein stability and function. Proteins are sufficiently stable to act effectively within cells. However, mutations generally destabilize structure, with effects on free energy that are comparable to the free energy of folding. Assays of protein functionality and stability in vivo enable a quick study of factors that influence these properties in response to targeted mutations. These assays can help molecular engineering but can also be used to target important (...) questions, including why most proteins are marginally stable, how mutations alter structural makeup, and how thermodynamics, function, and environment shape molecular change. Processes of self‐organization and natural selection are determinants of stability and function. Non‐equilibrium thermodynamics provides crucial concepts, e.g., cells as emergent energy‐dissipating entities that do work and build their own parts, and a framework to study the sculpting role of evolution at different scales.

En la actual campaña electoral uruguaya de 2019, se perfila un cuadro de descontentos generalizados que desborda claramente los estándares tradicionales de la política del país. Muchos de estos descontentos se articulan con diversos factores que los autores han venido destacando en trabajos anteriores, como señales de una mutación gradual pero efectiva de la política uruguaya. En continuidad con ese abordaje de investigación, en el artículo se indagará acerca de las posibilidades efectivas de que esta mutación política adquiera proporciones realmente (...) significativas en las actuales circunstancias, con la posibilidad de confirmación de "cisnes negros" que parecen atisbarse en la campaña electoral en curso. Para ello, luego de algunos discernimientos teóricos y metodológicos, se trabajará el itinerario de distintos indicadores de opinión pública a nivel nacional durante el período 1995-2017, vinculados con el objeto de estudio planteado. A partir de esos insumos, se realizarán algunas breves consideraciones de proyección analítica. (shrink)

A Gemaldegalerie de Dresden expõe uma pintura de Valdés Leal, executada entre os anos de 1656 e1658, uma das doze que executou para o convento dos Jerónimos de Sevilha mostrando os santos da Ordem. A figura histórica de Vasco Martins, leiriense, “ermjtam de prove vida”, fundador do convento da Penha Longa, é conhecida nos seus traços mais significativos, mas menos presente hoje está a sua iconografia e o culto que mereceu, aspectos sobre os quais nos debruçamos.

The origins and evolution of the Archaea, Bacteria, and Eukarya remain controversial. Phylogenomic‐wide studies of molecular features that are evolutionarily conserved, such as protein structural domains, suggest Archaea is the first domain of life to diversify from a stem line of descent. This line embodies the last universal common ancestor of cellular life. Here, we propose that ancestors of Euryarchaeota co‐evolved with those of Bacteria prior to the diversification of Eukarya. This co‐evolutionary scenario is supported by comparative genomic and phylogenomic (...) analyses of the distributions of fold families of domains in the proteomes of free‐living organisms, which show horizontal gene recruitments and informational process homologies. It also benefits from the molecular study of cell physiologies responsible for membrane phospholipids, methanogenesis, methane oxidation, cell division, gas vesicles, and the cell wall. Our theory however challenges popular cell fusion and two‐domain of life scenarios derived from sequence analysis, demanding phylogenetic reconciliation. (shrink)

El artículo se centra en comprender el desarrollo de las comunidades de aprendizaje, reflexionando sobre los procesos colaborativos en dos grupos de investigación. Corresponde a un relato de experiencia, cruzando los ojos de los dos autores durante un doctorado, realizado por el primero y supervisado por el segundo. Se evidencian acciones de aceptación, pertenencia y compartir, pero también conflictos derivados de las diferencias culturales entre individuos y grupos. En co-construcción de este artículo, que implicó la confrontación y complementariedad de testimonios (...) narrativos de una misma y diferente situación, se asume un proceso intersubjetivo y dialógico en la construcción del conocimiento.

As higher education teachers we undertook a self-study research focused on emotional education, during two school years. The analysis of the students’ portfolios and the teachers’ fieldnotes provide evidence to problematize some tensions and challenges identified along the process, namely for integrating personal, cultural and institutional dimensions, facing the unpredictability of a participative process and opening new paths. Students valued the work centred on their own goals, the building of a personal learning project in conjunction with a class collective project, (...) the relational practices based on an ethics of care, the diversity of mindfulness and meditation proposals, amongst others.

Uma questão que surge para aqueles que começam a trabalhar com a hermenêutica filosófica de Hans-Georg Gadamer consiste, em parte, na pergunta sobre os limites da relação da hermenêutica com a fenomenologia. Ou seja, até que ponto a hermenêutica expressa posições dependentes dos modos de pesquisa da fenomenologia. Neste texto, buscamos rastrear como essa relação acontece explicitamente nos textos de Gadamer, apontando que há uma consequencia prática da herança fenomenológica que é absorvida pela hermenêutica.

Entre os vários problemas filosóficos que tem ocupado os filósofos envolvidos com a pesquisa ética está aquele da objetividade do valor. Alguns teóricos defendem que não há objetividade nos juízos valorativos. Outros, os realistas, defendem que os juízos valorativos são tão objetivos quanto os juízos factuais. Aqui abordaremos a postura realista, em especial o realismo naturalista de Alasdair MacIntyre, e como esta postura lida com a questão da distinção entre fato e valor.

O presente artigo tem o objetivo de fornecer um rápido esboço do atual estado do debate em torno do conceito de justiça. Hoje não dispomos de um conceito único compartilhado do que significa justiça e isto devido ao fato das sociedades atuais serem pluralistas, tal fato gerou uma separação entre as esferas morais e políticas e consequentemente o termo justo tem hoje dois aspectos distintos, um moral e outro político.: Nowadays we do not have a shared unitary concept of means (...) justice, because our present societies are pluralistics. This fact generates a gap between moral and political spheres, and as a consequence the word “just” have today at least two distinct and large meanings: one moral and the other political. This paper aims to provide a quick sketch of the debate concerning those two meanings from the perspective of Alasdair MacIntyre’s theory. Keywords : Justice, Moral Community, Well-Being. (shrink)

Background The practice of health advocacy in nursing has been defined as a process aimed at promoting the independence and autonomy of users of health services, in addition to providing information on healthcare decision-making and offering support for decisions taken. Ethical considerations Ethics approval was not required to conduct this review. Aim This integrative review aims to synthesize evidence in the literature on health advocacy in professional nursing practice. Methods An integrative review methodology guided by Whittemore and Knalf was used. (...) Studies were identified by conducting searches on PubMed, Scopus, Web of Science, CINAHL, and LILACS databases. Of 2179 records, 34 studies matched the inclusion criteria. Results The main aspects involved in the practice of health advocacy by professional nurses are related to the ethical principles of the nursing profession, such as protecting patients seeking autonomy and care. Furthermore, the practice of health advocacy by nurses requires an empathetic attitude, responsibility, and assertive communication. Conclusion The diverse possibilities for the practice of advocacy synthesized in this study allow nurses to approach and become familiarized with the topic, being able to acquire and complement knowledge that will reflect on their professional practice in different work environments such as the educational field, in hospital practice, or basic health care.

In late 2019, an infectious disease with a high rate of human-to-human transmission was identified in Wuhan, China, which was called Covid-19. In a short time, this disease affected several regions of the world and became a pandemic, with huge impacts on people's lives and the environment. This article aims to investigate the existing relationships between health and the environment, at the moment of confronting Covid-19 in Brazil, focusing on the socioenvironmental issues of sanitation and agglomeration and its consequences/limits for (...) prevention/care in Public Health. For the development of the research, a systematic review was carried out between May and June 2020. The article brings aspects about the industrial revolution and its relationship with life forms; the issue of sanitation, agglomeration as a reflection of geographical inequalities and their impact on combating Covid-19. Thus, there is an urgent need to understand the various health measures that dialogue with environmental, social and political actions that need to be built, in the various dimensions, in order to fight socio-environmental inequalities.

This article reviews and discusses emerging evidence suggesting an evolutionarily‐conserved connection between injury‐associated exposure of cytoskeletal proteins and the induction of tolerance to infection, repair of tissue damage and restoration of homeostasis. While differences exist between vertebrates and invertebrates with respect to the receptor(s), cell types, and effector mechanisms involved, the response to exposed cytoskeletal proteins appears to be protective and to rely on a conserved signaling cassette involving Src family kinases, the nonreceptor tyrosine kinase Syk, and tyrosine phosphatases. A (...) case is made for research programs that integrate different model organisms in order to increase the understanding of this putative response to tissue damage. (shrink)
