We explore the intimate connection between spacetime geometry and electrodynamics. This link is already implicit in the constitutive relations between the field strengths and excitations, which are an essential part of the axiomatic structure of electromagnetism, clearly formulated via integration theory and differential forms. We review the foundations of classical electromagnetism based on charge and magnetic flux conservation, the Lorentz force and the constitutive relations. These relations introduce the conformal part of the metric and allow the study of electrodynamics for (...) specific spacetime geometries. At the foundational level, we discuss the possibility of generalizing the vacuum constitutive relations, by relaxing the fixed conditions of homogeneity and isotropy, and by assuming that the symmetry properties of the electro-vacuum follow the spacetime isometries. The implications of this extension are briefly discussed in the context of the intimate connection between electromagnetism and the geometry of spacetime. (shrink)

Using social information is not indiscriminate and being able to choose what to copy and from whom to copy is critical. Dogs are able to learn socially, to recognize, and respond to dog as well as human emotional expressions, and to make reputation-like inferences based on how people behave towards their owner. Yet, the mechanisms dogs use for obtaining and utilizing social information are still to be fully understood, especially concerning whether emotional cues influence dogs’ social learning. Therefore, our main (...) aim was to test the hypothesis that an emotionally charged interaction with the demonstrator of a “V” detour task prior to testing would affect subjects’ performance, by: changing the value of the information provided by the demonstrator or changing the valence of the learning environment. Our experimental design consisted of three phases: pre-test ; emotional display ; test. Only dogs that failed in pre-test were considered for analysis. We analyzed four dependent variables: success, time to solve the task, latency to reach the fence and matching the side of demonstration. For each, we used four models to investigate the effect of demographic factors; experimental design factors ; behavior of the dog; and side chosen and matching. All models took into account all trials and the first trials only. Our findings corroborate previous studies of social learning, but present no evidence to sustain our hypothesis. We discuss the possibility of our stimuli not being salient enough in a task that involves highly motivating food and relies on long and highly distracting interval between phases. Nevertheless, these results represent an important contribution to the study of dog behavior and social cognition and pave the way for further investigations. (shrink)

O presente artigo possui como tema a análise da separação dos poderes e a regra da democracia, além da possibilidade do Tribunal Constitucional ser composto por indivíduos nomeados pelo Presidente da República, não cumprindo a regra democrática, e fazer o controle de constitucionalidade das leis, criadas através de um processo democrático. Serão respondidos: a separação dos poderes obedece à regra democrática? Quando o Poder Legislativo deixa de cumprir sua função típica de legislar, abre a oportunidade para o Supremo Tribunal Federal, (...) como Tribunal Constitucional que é, criar, através do ativismo judicial, as normas lacunosas? Isso fere a regra democrática? (shrink)

In this paper I offer a characterization of the intellectual virtue of social inquisitiveness, paying attention to its difference from the individual virtue of inquisitiveness. I defend that there is a significant distinction between individual and social epistemic virtues: individual epistemic virtues are attributed to individuals and assessed by the quality of their cognitive powers, while social epistemic virtues are attributed to epistemic communities and are assessed by the quality of the epistemic relations within the communities. I begin presenting Lani (...) Watson's characterization of the (individual) practice of questioning and its related intellectual virtue, inquisitiveness. While she does not employ normative language, I show that her description can be constructed through four norms. Then, based on an account of epistemic communities, I defend that, while epistemic virtues attributable to individuals have norms regulating cognitive powers, epistemic virtues attributable to epistemic communities have norms regulating social epistemic interactions and shared epistemic responsibility. I then present a robust characterization of the epistemic virtue of social inquisitiveness through its social epistemic norms: DISTRIBUTION, ACCESSIBILITY, SOCIAL SINCERITY, SOCIAL CONTEXT, and FREQUENCY. I respond to two possible objections to my account and conclude by offering suggestions to broaden the scope of the epistemology of questioning. (shrink)

Em 25 de maio de 2020 um homem negro americano, chamado George Floyd, morreu após ser asfixiado por mais de oito minutos por um policial branco na cidade de Minneapolis, nos EUA. Violentos protestos se seguiram ao longo do país com cartazes contendo as últimas súplicas de Floyd: “I can’t breathe” (Eu não consigo respirar). Pouco tempo depois, ainda sob o calor dos horrores da hora, outro fato também vinculado ao acontecimento recém-referido roubou a cena e chamou a atenção dos (...) principais meios de comunicação ao redor do planeta: tratava-se de um casal branco americano de moradores de um bairro nobre, em frente ao jardim de sua mansão de dois andares, esbravejando contra um grupo de negros que se dirigia para um protesto e resolveu cortar caminho passando por entre os casarões do bairro onde se encontrava o referido casal. O “detalhe” marcante dessa demonstração gratuita de ódio por parte do casal branco é que, enquanto o homem portava um potente fuzil moderno e a mulher uma pistola automática, ambos apontavam as armas contra os transeuntes negros que tiveram a “audácia” de se deslocar por entre os casarões da elite americana. O mais absurdo da situação foi um momento de transtorno colérico do casal branco que em certa altura do descontrole chegou a apontar a arma um contra o outro, revelando o completo desvario em que ambos se encontravam [...].

Neste capítulo demonstra-se a importância da educação cidadã para a vida de cada indivíduo que opta pela prática da autoinseminação, pois por meio das informações adquiridas, as pessoas teriam uma Competência Crítica em Informação, desenvolvendo dessa forma, certo entendimento de possíveis consequências e efeitos da técnica da Autoinseminação, fato que poderia levá-las à procura por técnicas mais seguras para satisfação do desejo de ter um filho. É exposto durante todo o embasamento que, quanto mais se conquista clareza e explicações através (...) da prática educativa, se torna perceptivo o instrumento privilegiado que se tem disponível - a educação, entretanto, observa-se também pouca exploração desse recurso.

The internationalization strategies are analyzed in this article in order to understand the power of the Brazilian media. The study is based on bibliographic and documental research, interviews and case studies. It comes to the following findings: Brazilian media groups need a better understanding of their performance in the local and the international scenario; they must know and respect all legislation, as well as their local insertion, and the public targeted to validate their necessities.

Com razão se costuma dizer que um problema bem posto é problema meio resolvido E o contrário também é verdade Ora, definir bem um termo tem grande analogia com pôr bem um problema- a correcta definição dos termos que usamos é condição indispensável para a adequada abordagem e debate de qualquer tema A ponto de Jaime Balmes ter podido dizer, com alguma dose de optimismo- si definimos no discutiremos Bem o sabiam os escolásticos, que por esse motivo faziam preceder qualquer (...) disputa pela fase ad terminos, na qual todos os termos que iriam utilizar eram cuidadosamente definidos A história da Ética dá-nos a conhecer alguns casos confirmativos, verdadeiramente exemplares, tanto da importância das definições exactas como das consequências negativas e dificuldades levantadas pelas formulações incorrectas Dois desses exemplos serão aqui lembrados- os dos problemas com que os moralistas se tiveram de confrontar em consequência das deficientes definições de mentira e mutilação A definição de mentira que vigorou durante séculos no mundo ocidental foi a que propôs S Agostinho, primeiro e quase único autor da Antiguidade a estudar desenvolvidamente o tema Este apaixonado pela verdade preocupou-se seriamente com a mentira, e não apenas por ela ser o oposto da verdade- também porque a sua própria concepção de mentira e, consequentemente, a definição que dela propôs, não se lhe apresentava isenta de dificuldades.

The Green Revolution is often seen as epitomising the dawn of scientific and technological advancement and modernity in the agricultural sector across developing countries, a process that unfolded from the 1940s through to the 1980s. Despite the time that has elapsed, this episode of the past continues to resonate today, and still shapes the institutions and practices of agricultural science and technology. In Brazil, China, and India, narratives of science-led agricultural transformations portray that period in glorifying terms—entailing pressing national imperatives, (...) unprecedented achievements, and heroic individuals or organizations. These “epic narratives” draw on the past to produce meaning and empower the actors that deploy them. Epic narratives are reproduced over time and perpetuate a conviction about the heroic power of science and technology in agricultural development. By crafting history and cultivating a sense of scientific nationalism, exceptionalism, and heritage, these epic narratives sustain power-knowledge relations in agricultural science and technology, which are underpinned by a hegemonic modernization paradigm. Unravelling the processes of assemblage and reproduction of epic narratives helps us make sense of how science and technology actors draw on their subjective representations of the past to assert their position in the field at present. This includes making claims about their credentials to envision and deliver sustainable solutions for agriculture into the future. (shrink)

The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

Phosphatidylinositol‐3‐kinases (PI3Ks) are lipid kinases that produce 3‐phosphorylated derivatives of phosphatidylinositol upon activation by various cues. These 3‐phosphorylated lipids bind to various protein effectors to control many cellular functions. Lipid phosphatases such as phosphatase and tensin homolog (PTEN) terminate PI3K‐derived signals and are critical to ensure appropriate signaling outcomes. Many lines of evidence indicate that PI3Ks and PTEN, as well as some specific lipid effectors are highly compartmentalized, either in plasma membrane nanodomains or in endosomal compartments. We examine the evidence (...) for specific recruitment of PI3Ks, PTEN, and other related enzymes to membrane nanodomains and endocytic compartments. We then examine the hypothesis that scaffolding of the sources (PI3Ks), terminators (PTEN), and effectors of these lipid signals with a common plasma membrane nanodomain may achieve highly localized lipid signaling and ensure selective activation of specific effectors. This highlights the importance of spatial regulation of PI3K signaling in various physiological and disease contexts. (shrink)

This essay considers insects’ place-making powers in history of science topics. Insects have co-shaped the geographies of knowledge production throughout history in three primary dimensions: through their size, density, and multiplane existence. Insects’ miniature worlds have helped humans to create trans-scale analogies. Their spatial transgression and swarming capacity have overwhelmed people, including field researchers, contributing to the making of the places where science is produced. Finally, insects’ “ontologically alien” ways of engaging with environments (e.g., flying and living underground) have offered (...) valuable material for humans’ imaginings of their own realities. By prioritizing insects’ own spatial characteristics, this tripartite typology of human/insect entanglements intends to spur new ways of writing histories of science that engage with space and place.

This article identifies a double allusion to the tragic characters of Phaedra and Eriphyle in Amm. Marc. 14.1.3 and considers its possible meanings. In combination, these allusions evoke the double nature of the story of Eriphyle, therefore functioning as a reference to the double nature of Caesar Gallus’ depiction in Ammianus. The double allusion consequently forms part of Ammianus’ tragic style throughout Book 14. Having identified the presence of this double allusion, the article illuminates its possible meaning by connecting Ammianus’ (...) passage to the Virgilian rewriting of the description of Eriphyle in Homer.

The proper limit to paternalist regulation of citizens' private lives is a recurring theme in political theory and ethics. In the present study, we examine the role of beliefs about free will and determinism in attitudes toward libertarian versus paternalist policies. Throughout five studies we find that a scientific deterministic worldview reduces opposition toward paternalist policies, independent of the putative influence of political ideology. We suggest that exposure to scientific explanations for patterns in human behavior challenges the notion of personal (...) autonomy and, in turn, undermines libertarian arguments against state paternalism appealing to autonomy and personal choice.

It is an intimate experience for us to think, to understand and to perceive things as being identical to themselves, and to suppose, consequently, that things are truly “what” they are. Something is always conceived as itself. The given is given full of itself in all its modifications. For instance, I can think or perceive partially some lips, I can see them almost in their whole or in some of their aspects, or just see them disappear. But it does not (...) seem to be possible to think or to perceive a given as almost itself, as an aspect or as part of itself. It is the aim of this work to study the assumptions and conditions for the original position of sameness in experience, just as it occurs in the synthesis of the datum singular and distinct. The polarization of single tone (einstimmig) intentional rays in an αvτó already contains the aporiae peculiar to the experience of the identical, whose revelation shall lead us, on the one hand, to one of the nuclei of the analysis of passive synthesis, and, on the other hand, to point up how critical revision of the numerical or extensional model of self-identity is for the unity of meaning. Then, it will be a question of pointing out the reasons why in a phenomenology of identity, the renunciation of the phenomenological legitimacy of the αvτó as a guarantee for the different positions of identity must be observed.

We comment on the last chapter of Henrich where the author offers a ‘key’ to Hegel’s Logic focusing on the problem of the passage from self-reference to determination in the beginning of the Logic. We argue that what he offers as a ‘key’ is actually a reduction of Hegel to the logic of understanding from the point of view of an autonomous Ego; consequently, he excludes dialectics. Contrarily, we present Hegel’s own solution, eliciting the remark where he shows that the (...) proposition “Being and Nothing are the same” negates itself insofar as it is uttered and reflected on the Other’s understanding. We conjecture that this remark offers a privileged point from which to consider the connection Hegel-Lacan, provided we recognize the Absolute in Hegel as the big Other in Lacan. We suggest that the dialectical identity of identity and difference is actually an operation in the Agora and that the Hegel-Marx-Lacan theory can be properly denominated dialectical materialism. We also offer an answer to Žižek’s question of how a “neutral medium of designation” can emerge within a “life-world practice” or out of a “universe of matter. (shrink)

Political realism points out that politics is to create and sustain a legitimate order in a context of persistent disagreement, with the possible surge of conflicts, and where political power inevitably uses coercion. Political realists contend that modus vivendi is a contingent political arrangement at the level of the political constitution that allows diverse groups of people to coexist peacefully. Proposals of modus vivendi do not say enough about how to manage disagreements and conflicts. In this paper, I argue that (...) proposals of agonistic democracy supply this lack. I contend that agonistic democracy proposals share the premises of political realism and contribute to the sustainment of a liberal modus vivendi. (shrink)

O presente artigo tem como objetivo primordial articular as experiências de iniquidade e sofrimento a partir da operacionalização de alguns conceitos decisivos das obras de Hannah Arendt e Byung-Chul Han. Nesse sentido, pretendo mostrar que uma das formas hegemônicas de experiência do mal na contemporaneidade se revela na produção de vidas descartáveis em meio a sistemas político-culturais violentos, que se caracterizam por estar em constante devir e por reduzir os devires à própria descartabilidade humana. Isso se revela tanto no mal (...) radical presente nos campos de concentração nazistas, quanto na ditadora da positividade produtivista inerente a psicopolítica neo-liberal. (shrink)

The study of conscious experience per se has not kept pace with the dramatic advances in PET, fMRI and other brain-scanning technologies. If anything, the standard approaches to examining the 'view from within' involve little more than cataloguing its readily accessible components. Thus the study of lived subjective experience is still at the level of Aristotelian science, leading to a widespread scepticism over the possibility of a truly scientific study of conscious experience. Drawing on a wide range of approaches -- (...) from phenomenology to meditation -- The View From Within examines the possibility of a disciplined approach to the study of subjective states. The focus is on the practical issues involved. (shrink)

The question whether ethical behavior is biologically determined may refer either to thecapacity for ethics (e.i., the proclivity to judge human actions as either right or wrong), or to the moralnorms accepted by human beings for guiding their actions. My theses are: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution.Humans exhibits ethical behavior by nature because their biological makeup determines the presence (...) of the three necessary, and jointly sufficient, conditions for ethical behavior: (i) the ability to anticipate the consequences of one's own actions; (ii) the ability to make value judgements; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself, but as a necessary consequece of man's eminent intellectual abilities, which are an attribute directly promoted by natural selection.

The complex relations between Christianity and science seem to present a critical point in evolutionary theory, especially for the challenges it poses to the doctrine of original sin. I investigate the precise senses in which evolution threatens the Augustinian/Reformed formulation of original sin, analyzing each of the six tenets of the doctrine vis a vis nine evolutionary claims, as well as the supposed clash between the narratives of evolution and Christianity. I show that the threat is less impressive than it (...) is usually assumed, and I highlight where the conflict really lies. I defend that it is possible to remain faithful to the core of the doctrine of original sin and to accept the reliability of evolution as a scientific theory. I present three scenarios for “Adam and Eve” and interpret them using two different models. I favor the understanding of Adam and Eve as the whole initial human bottleneck viewed through the lens of a multilevel model. (shrink)

This article shows how macro-historical processes of change can activate robust and enduring forms of citizenship practice, providing both survey-based evidence for this claim and a theorization of the causal mechanisms involved. Focusing on the case of Portugal, where democratization followed the historically unusual path of social revolution, we examine survey data on civic practice covering twenty countries and find Portugal to be a world leader in public participation in the electronic public sphere. When we examine the subsection of the (...) population socialized politically in the country’s post-revolutionary democracy, we find another important indicator of lively citizenship practice. The article takes the examination of this specific national case as the basis for developing an argument of broad theoretical relevance on the social underpinnings of lively and participatory citizenship practice. With an empirical foundation for our claims in survey data and other sources, our analysis of Portugal offers an interpretation of the case, leading to substantial revision of assumptions in the extant literature. More importantly, through our examination of this case, we show how large-scale macro-historical processes of change can encourage lively civic practice manifested at the individual level. Our argument highlights the importance of hierarchy-challenging collective experiences that reconfigure cultural frameworks and reorient the character of institutional practice. We take up the implications of this argument for cases lacking a history of revolution and find certain parallels with national cases shaped by movements of social reform as in the social democracies of Scandinavia.

Uma assembleia com as dimensões do Concílio Vaticano II necessariamente aglutinaria diversificadas correntes e perspectivas. No episcopado brasileiro a heterogeneidade também foi uma marca. Considerando tais dados, este artigo foi escrito com dois objetivos maiores: identificar transversalidades nas formas de pensar e agir de Proença Sigaud e Helder Camara, a partir dos temas propostos para o Concílio e analisar afinidades/convergências e oposições/divergências existentes entre as suas posições, respectivamente conservadoras e progressistas, sobretudo a partir das respostas que elaboraram às consultas solicitadas (...) na fase antepreparatória; perpassando o trabalho, há discussões remetendo aos grupos a que se associaram e às articulações estabelecidas, bem como aos seus epistolários e questões neles tratadas. Baseado em pesquisas bibliográfica e documental – realizada, esta, nos arquivos do Instituto Dom Helder Camara e da Cúria Arquidiocesana de Diamantina – com o artigo foi possível reforçar o entendimento de que a diversidade de perspectivas doutrinais e pastorais é fato inconteste, ainda que salvaguardada a unidade; outrossim, a transversalidade evidenciou, a partir da abordagem de temas sociopolíticos e religiosos, a existência de preocupações semelhantes que implicavam, nas posições majoritariamente antagônicas dos dois, igual empenho pela adoção de medidas, ainda que habitualmente díspares, no tocante à forma de analisá-los e enfrentá-los.

Nosso objetivo, no presente artigo, é propor uma articulação entre a teoria da individuação de Gilbert Simondon e a teoria da investigação de John Dewey. Em relação à primeira, serão enfatizados os aspectos “biológico” e “psíquico” de individuação; quanto à segunda, ressaltaremos seus principais elementos naturalistas e epistemológicos, assim como os conceitos mais gerais de “experiência” e de “natureza” de Dewey. Defenderemos que o processo de individuação tem estreita relação com a capacidade, possuída por todo indivíduo vivo, de solucionar problemas (...) ou situações de conflito resultantes de sua constante interação com o ambiente. Proporemos, mais precisamente, uma conexão teórica entre o princípio ou conceito de individuação e a ideia de que existe no organismo vivente uma aptidão investigativa que não apenas restaura seu equilíbrio “metaestável”, como também, e ao mesmo tempo, lhe proporciona sempre uma nova individualidade, tanto biológica como psíquica. Esperamos obter, como resultado deste processo de síntese envolvendo as ideias de Simondon e de Dewey, uma compreensão ampliada das respectivas teorias da individuação e da investigação. (shrink)

Con el Neoliberalismo como modelo económico imperante en los últimos 30 años, el comportamiento consumista de la mayoría de las sociedades occidentales y mediorientales que se incorporaron a la economía mundial desde la revolución asiática, ha jugado un papel importante en la consumación de mayores recursos naturales, ya que concentraron su desarrollo inicial en el uso y exportación de materias primas y bienes del sector primario de las economía. Debido a que la idea de progreso occidental se afincó, entre otras (...) cosas, en el consumo indiscriminado de bienes ‘efímeros’, el ritmo de frenético de la productividad y el reemplazo de los bienes que pasan de moda por la obsolescencia programada, han generado mayor contaminación y deterioro ambiental. En este sentido, el artículo argumenta sobre la necesidad de implementar otros modelos o ideales de vida y de progreso ante el daño ambiental y social generado por la explotación de los recursos naturales en los países latinoamericanos durante el periodo del neoliberalismo, y el creciente nivel de contaminación y generación de desechos. A partir de los postulados de Vattimo sobre el fin de la Modernidad, se argumenta sobre el fin de la idea de progreso occidental y la emergencia de otros ideales y estilos de vida. Finalmente se exponen las razones que hacen necesario el cambio de modelo instando a la reducción voluntaria del consumo y el decrecimiento económico como alternativas de desarrollo desligadas de la idea progreso postulada en el mundo occidental, con base en la cosmovisión ancestral kichwa del Buen Vivir o Sumak Kawsay.

This article departs from the consideration that global communication is not only a reality but also a challenge. This is because most of our communication does not involve dialogue but remains mere communication without achieving the creativity implied in true conversation. Departing from Gordon Pask’s warning, in 1980, that too much togetherness would be hazardous in future information environments, this article proposes a playful displacement of images – from network to lacework. The aim is to help us refine our gaze (...) into the interconnectedness of the world, or at least, into the intricacies of our contemporary culture and its global communication. The idea is that by using lace as an inspirational image we may go beyond the hazards of uniformity and triviality of our excessive togetherness. By doing so, we would allow space for a variety of local patterns of dialogues, articulated around unspoken tensions and thus, allowing the emergency of genuine conversation. (shrink)

Why is Butterfield's best-seller The Origins of Modern Science (1949) such a powerful big picture, nearly impossible to move away from? Considered in the context of his life, the contrast between his attacks on Whig history and the contents of his best-seller reveals that his big picture of science continues at the centre because of his spiritual beliefs and practices. Butterfield did not make explicit his Christian (Methodist) world view to his history of science readers, although one could infer this (...) from his point that Christianity and the Scientific Revolution were the most significant events in universal history, transcending cultural boundaries. As long as Christian beliefs and practices continue to be at the centre of Western Society, so will Butterfield's big picture be at the centre. Western society is a Christian civilization. For Butterfield, the meaning of history is Christianity and The Origins of Modern Science is very much a Christian statement of the evolution of knowledge acquisition in Western society. To de-centre The Origins would require first a de-centred view of Christianity. (shrink)

This exploratory study is focused on the perceptions of science communication practitioners about the activities of scientists and the audiences of the marine sciences outreach in Portugal. Using the qualitative method of thematic analysis and collecting data through semistructured interviews of 14 practitioners of diverse professions, backgrounds, ages, and stages of career, it was found that the role of marine scientists in this area is traditionally viewed as reduced, but with a slight improvement in the past 5 to 10 years. (...) Despite having a historical connection with and curiosity about the sea, audiences were considered to have a mostly utilitarian interest in the marine sciences. Most practitioners had a view of science communication connected to the knowledge deficit model, with a minority articulating a more dialogical model. Although there are signs of conflict between science communicators and scientists, the proliferation of training opportunities in science communication at the national level, the perceived increase of interest and participation of marine scientists in public communication in the past years, and the consolidation of science communicators as part of the scientific community offer positive prospects for the future of outreach of marine sciences in Portugal.
