Em 2019, o Papa Francisco convocou jovens para refletir sobre como alcançar uma economia mais justa e inclusiva. O livro "Realmar a Economia: a Economia de Francisco e Clara" é resultado dos estudos do Grupo de Reflexão e Trabalho para a Economia de Francisco e Clara (PUC Minas), organizado pelo sociólogo Eduardo Brasileiro. Nesta resenha, iremos apresentar brevemente alguns pontos debatidos na obra, com o intuito de incentivar a leitura desse importante trabalho.

With the aim of reflecting on a Pedagogy of the Franciscan Schools, the Franciscan Itinerary took place from February to December 2022, with the participation of collaborators and teachers from the schools maintained by the Charitable and Literary Society of St. Francis of Assisi - North Zone (SCALIFRA - ZN). The training consisted of webinars and evaluative activities, with themes extracted from works from the Franciscan writings. This experience report describes how the Itinerary was planned, as well as its main (...) results. (shrink)

ObjectiveThis study aims to analyze sociohistorically how the normative patterns of hegemonic masculinity produced impacts on men’s health/mental health in the context of the COVID-19 pandemic.MethodsA qualitative study from a socio-historical perspective was conducted with 50 men based on an online survey. A semistructured form was applied. The data were analyzed by the Collective Subject Discourse method, interpreted in the light of the context of epidemic disease and hegemonic masculinity.ResultsThe experience of the pandemic exposed the normative patterns of masculinities from (...) the consummation of acts representative of the pandemic context, which incited men to deny the existence of COVID-19 disease and to delay the understanding and adoption of measures to protect and control COVID-19. As a repercussion, men presented conflicts in the regulation of emotions; presented emotional suppression; were more reactive; felt threatened regarding the loss of the role of family provider, virility; and revealed a sense of invulnerability, added to the weakening of self-care.ConclusionThe discourse revealed that the men’s behaviors are consistent with the characteristics of hegemonic masculinity, but express signs of recognition that this behavior causes harm to themselves and their health.

Formative intervention methodologies, such as the Change Laboratory, are increasingly being used in work environments. However, the learning process entailed in the application of these methodologies has received insufficient attention and may be facilitated through the use of learning platforms. We examined the development of learning and training strategies for implementing formative interventions, drawing on the experiences of a research group focusing on workers’ health. Information obtained from individuals involved in CL formative activities was analyzed and interpreted using Cultural-Historical Activity (...) Theory and the theory of expansive learning. The process of learning to implement formative interventions unfolded gradually, beginning with the interventionists’ initial exposure to abstract concepts that they subsequently internalized via various mediations and applied in concrete situations. Four key interventionist training strategies used to foster collective learning were identified: promoting dialogues and exchange of experiences, creating environments for continuous learning and permanent discussion, creating spaces for experimentation and the practical application of concepts, and the use of the double stimulation method during training programs.

RESUMO A série Black Mirror, transmitida entre 2011 e 2023 pela Netflix, tornou-se um fenômeno de mídia e seus episódios mostraram formas de interação homem-máquina (terminologia também referida como humano-computador). O nome da série se refere ao fato de que, quando uma tela é desligada, ela se torna um espelho negro que reflete a imagem do usuário. Este artigo1 tem como objetivo analisar os efeitos da interação homem-máquina nas organizações produtivas apresentadas em Black Mirror. Esta pesquisa utilizou a análise do (...) discurso, principalmente a partir das contribuições de Mikhail Bakhtin. O método consistiu em três etapas que contaram com a colaboração de estudantes de graduação e pós-graduação em Engenharia de Produção, integrando ensino e pesquisa e desenvolvendo o senso crítico dos pesquisadores-iniciantes. Os resultados indicam que, nas organizações apresentadas na série Black Mirror, há uma transição do conceito de fatores humanos para fatores ciborgues, bem como o uso da interação homem-máquina para promover o controle social.

Neste artigo, colocamos a questão sobre o estatuto da Física no pensamento de René Descartes em meio a duas leituras divergentes. De um lado, apresentamos e criticamos a interpretação idealista de Martial Gueroult em torno do problema e, noutra perspectiva, apresentamos e defendemos a interpretação realista-pragmática, de Zeljko Loparic e Érico Andrade, como sendo a mais adequada para se compreender a natureza da física no pensamento cartesiano. O objetivo central é saber como Descartes concebe a sua própria ciência hipotética (...) frente às exigências metodológicas que ele mesmo extrai da matemática. Após entendermos em que medida a relação entre metafísica, matemática e física não ocorre de modo pacífico no interior do sistema cartesiano, passamos ao tratamento específico das duas interpretações, destacando seus respectivos compromissos filosóficos e suas diferentes escolhas textuais. Apesar da vasta literatura especializada sobre a obra de Descartes, no Brasil, o debate em torno da ciência cartesiana ainda é incipiente quando comparamos com a quantidade de artigos e livros que priorizam os temas clássicos da sua metafísica. Com o intuito de diminuir tal lacuna, retomamos este tema específico do pensamento de Descartes, explicitando as mediações e problematizações que lhe são inerentes. (shrink)

En la actualidad, aún se desconoce el verdadero alcance de la vasta cultura de Lope de Vega, pues, aunque se sabe que fue un gran lector, que legó más de 1500 libros, sus títulos se han perdido a lo largo de la historia. No obstante, en sus obras trasciende una serie de textos que contribuyeron a su formación. En el presente trabajo se analiza La Arcadia, considerada la novela pastoril más erudita del Siglo de Oro, desde la perspectiva de los (...) agentes terapéuticos. En esta obra se mencionan remedios de procedencia herbal, de procedencia mineral y también de procedencia animal. Los resultados confirman que Lope de Vega pudo utilizar una serie de textos científicos en sus citas sobre la materia terapéutica. Entre ellos cabe destacar a Andrés Laguna y su Dioscórides y Plinio el Viejo, cuya Historia Natural pudo haber consultado como fuente primaria, a través de alguna traducción comentada, como la de Gerónimo de Huerta o a través de alguna otra obra basada en ella, como el opúsculo de Constantino Castriota, pues, en este último caso, se encuentran párrafos muy similares y, en algunos casos, casi literales. Nowadays, the true extent of the vast culture of Lope de Vega is still largely unknown. Although it is known that he was a great reader, who bequeathed more than 1500 books, his titles have been lost throughout history. However, a series of texts that contributed to his education become known in his works. In the present paper, La Arcadia, considered the most erudite pastoral romance of Spanish Golden Age, is analyzed from the therapeutic perspective. Remedies of herbal origin, of mineral origin and also of animal origin are mentioned in this novel. The results achieved confirm that Lope de Vega was able to use a series of scientific texts in his quotations on the therapeutic subject. Among them, it is worth mentioning Andres Laguna, and Pliny the Elder, whose Natural History could have been consulted as a primary source, through some commented translation, such as that of Geronimo de Huerta, or through some other work based on it, like Constantino Castriota's opuscule. In the latter case, there are very similar and, in some cases, almost literal paragraphs. (shrink)

This paper discusses the possibility of an absolute vacuum - a space without any substance. The motivation of this study is the contrast between most philosophers, up to Descartes, who stated that a vacuum was impossible, and the 17th century change of outlook, when the possibility and effective existence of the vacuum was accepted after the experiments of Torricelli and Pascal. This article attempts to show that, contrary to the received opinion, the acceptance of an ether is preferable to the (...) acceptance of a vacuum for several reasons. First: it is impossible to provide an empirical proof of the non-existence of the ether; second, an absolute vacuum is unthinkable; third, the ether concept is useful for the understanding of physical phaenomena; and fourth, the hypothesis of an ether in apparently void spaces is useful for the future development of science. The paper also endeavours to show that no recent advance of science changed those conclusions and that no future development can change them. (shrink)

Dans cet article nous étudions le Trattato della sfera de Galilée, écrit avant 1600. C’est un traité d’astronomie géocentrique qui suit la structure du Tractatus de sphæra de Johannes de Sacrobosco. Nous analysons quelques particularités du traité, en le comparant à d’autres travaux astronomiques du xvie siècle, et nous discutons ses sources probables. Nous soutenons que l’influence du commentaire de Christoph Clavius sur la Sphæra de Sacrobosco ne peut pas être considérée comme son influence unique ou principale. Le traité de (...) Galilée était probablement inspiré par la Sfera del mondo de Piccolomini, un travail qui anticipait plusieurs particularités du Trattato della sfera. Cette influence est établie par de nombreuses annotations de Galilée trouvées dans un exemplaire du livre de Piccolomini. (shrink)

This paper studies Lamarck's scientific method both from the point of view of his methodological discourse and according to his scientific praxis. Lamarck's methodology is compared to Condillac's as well as to that of the idéologues - a group in which Lamarck is usually included. The analysis of this paper shows that Lamarck's methodological discourse is very similar to Condillac's, but his scientific praxis does not follow this view. Instead of following an empiricist approach, Lamarck's work is grounded upon general (...) metaphysical principles concerning nature. Thus, from the ideologues's point of view, Lamarck's work should have been rejected -and that is what really happened - as being a mere metaphysical system grupo no qual se costuma incluir o próprio Lamarck. Mostra-se que o discurso metodológico de Lamarck assemelha-se ao dos ideólogos; no entanto, sua prática científica não se coaduna com esse enfoque. Em vez de seguir uma abordagem empirista, a obra de Lamarck se fundamenta em princípios metafísicos gerais sobre a natureza. Sob o ponto de vista dos ideólogos, seu trabalho deveria ser rejeitado - o que de fato ocorreu - como um mero sistema metafísico - no sentido pejorativo utilizado pelos seguidores de Condillac. No entanto, o presente artigo argumenta que esse é justamente um importante e inovador aspecto da obra de Lamarck, que permitiu a eclosão do evolucionismo moderno. (shrink)

There is a death by suicide in the world every 40 seconds, and suicide is the second leading cause of death for 15–29-year-olds. Experts say that one of the best ways to prevent suicide is for those in distress to hear from people who care about them. Facebook is in a unique position—through its support for networks and friendships on the site—to help connect a person in these difficult situations with people who can support them. Connecting people with the resources (...) they need is part of Facebook’s ongoing efforts to help build a safe community inside and outside of Facebook. This article provides a brief overview of how Facebook’s work to develop suicide prevention tools started and evolved, and the ethical considerations which surfaced during the process in the form of concrete product decisions around the implementation of these tools. This article is structured into three sections. Section 1 reviews what has been done in this space and lists and briefly describes other suicide prevention apps and tools. Section 2 describes Facebook’s overall approach to suicide prevention. Here, we’ll delve first into how that approach originated and how it was influenced by the external community’s proactive interactions with Facebook, highlighting our unique position to help address the problem. Afterwards, we’ll explain how that approach evolved, describing its various stages and iterations: understanding, reactive reporting, queue prioritization, and proactive reporting. This section describes the tools and resources Facebook has developed for people who may be at risk. Particular attention is devoted to the use of ArtificiaI Intelligence and Machine Learning to detect posts or live videos where someone might be expressing thoughts of suicide. Section 3 will elaborate on the ethical questions addressed when developing our approach and when making concrete product decisions to implement our suicide prevention tools. In this last section, we’ll expound the competing values and interests that were at stake during the product development process, and how we reached ethical balances between them. (shrink)

Isometry hypotheses are propositions that assert the constancy of a specific physical magnitude of a system under prescribed conditions. This paper addresses the controversy concerning the conventionality of this type of hypotheses. It discusses several instances of isometry hypotheses and it is shown that experimental facts can be invoked to criticise (or "refute") isometry hypotheses, just as other types of hypotheses. This proves that isometry hypotheses, and the choices of measurement standards that are grounded in such hypotheses, are not merely (...) conventional. (shrink)

Este artigo questiona a dimensão crítica da democracia analisada por Sheldon S. Wolin. A partir da década de 1980, o impulso de Wolin de diagnosticar as falhas da democracia americana ao conectar o liberalismo ao totalitarismo se manifesta de uma nova maneira. Ele observa que, no processo de lutar ostensiva- mente contra o totalitarismo durante a Guerra Fria, o próprio governo americano passou a incorporar uma forma totalizante de poder. Essa crítica culmina em seu diagnóstico de uma crise do século (...) XXI: a condição neoliberal de “totalitarismo invertido”. Aqui Wolin argumenta não apenas que o sistema político americano compartilha algumas características com o totalitarismo, mas também que está começando a constituir uma nova versão do totalitarismo emergindo de dentro, e não em reação ao liberalismo. Palavras-chave: Democracia. Totalitarismo. Liberalismo. (shrink)

In the first chapter of the Origin of species and in two chapters of the Variation of animals and plants under domestication, Darwin discusses the origin of domestic pigeons, claiming that all the known breeds were produced from a single species: Columba livia, the rock pigeon. The detailed defense of this point is of high relevance in Darwin’s argumentation strategy, since the differences between the several domestic breeds is so large that, if they were found in the wild, they could (...) be classified as different species or genera. If man was able to produce such large differences, it becomes plausible that nature can produce even larger differences, and therefore the process of natural selection becomes acceptable. Darwin emphasizes the enormous differences between the several domestic breeds (that may have dissimilar cranial structures and a varying number of vertebrae), and at the same time he attempts to show that there are connections and transitions between the extreme types, arguing for their common origin. One of the several interesting parts of his argument is an experiment of crossing between widely different breeds, which led him to obtain pigeons similar to the wild species. The detailed analysis of Darwin’s study of pigeons shows the extreme care he took in his attempt to provide strong arguments for his theory. RESUMO: No primeiro capítulo do Origin of species, e em dois capítulos do Variation of animals and plants under domestication, Darwin discute a origem dos pombos domésticos, defendendo que todas as raças conhecidas provêm de uma única espécie: Columba livia, o pombo de rocha. A defesa detalhada desse ponto é de grande importância na estratégia argumentativa de Darwin, pois as diferenças entre as várias raças de pombos são tão grandes que, se fossem encontradas em estado selvagem, poderiam ser classificadas como espécies ou gêneros diferentes. Se o homem foi capaz de produzir mudanças tão grandes como essas, torna-se plausível que a natureza possa produzir diferenças ainda maiores, e assim o processo de seleção natural se torna aceitável. Darwin enfatiza as grandes diferenças entre as raças de pombos (que chegam a possuir, por exemplo, diferentes estruturas cranianas e diferentes números de vértebras), e ao mesmo tempo procura mostrar a existência de nuances e transições entre os tipos extremos, para defender a origem comum. Um dos aspectos interessantes de sua argumentação é um experimento de cruzamento entre raças bem diferentes, através da qual obtém pombos semelhantes à espécie selvagem. A análise detalhada desse estudo de Darwin mostra o extremo cuidado que ele tomava para tentar proporcionar fortes argumentos a favor de sua teoria. (shrink)

O presente artigo tem como objetivo reconstruir argumentos cen-trais, desenvolvidos por Robert Nozick, acerca das posições extremas que não diferenciam Estado-providência e Estado totalitário na política dos libertarianos norte-americanos, isto é, sobre as afinidades percebidas por Nozick com as teses desta corrente de pensamento, embora se afastando num ponto essencial: a questão do Estado. Ao contrário da teoria anar-quista, o Estado mínimo é preferível ao estado de natureza, tal como John locke o descreve.

Há um diálogo entre os estudos antropológicos e literários não só porque a literatura está dentro do âmbito da antropologia cultural, mas também porque a literatura de um povo reflete substancialmente os aspectos da sua cultura e sua visão de mundo. Este trabalho investiga as representações de classe, raça e relações raciais em “O Romance d'A Pedra e o Príncipe do Sangue do Vai-e-Volta”, um romance do autor brasileiro contemporâneo, Ariano Suassuna (1927). Em primeiro lugar, pretende-se demonstrar como a representação (...) de Suassuna da cultura popular reflete classe, raça e relações raciais sociais em uma área particular do Brasil, o Nordeste, tradicionalmente rural. Posteriormente, investigar como a comunicação de massa, especialmente os veículos culturais de televisão e cinema, utiliza a literatura para tentar mudar ou espalhar e perpetuar atitudes racistas e formas de pensamento. Mesmo que estudos modernos tenham mostrado que o conceito de "raça" é uma construção cultural e uma falácia, a literatura e a cultura de massa exploram identidades deliberadas com base em estereótipos recebidos. Os debates linguísticos e culturais de uma cultura e país racialmente híbrido, como o Brasil, não podem deixar de considerar os conceitos de "raça" e "grupos étnicos", pois o Brasil é um país que herdou as tipologias de classe, cor e preconceito patriarcal e agrário baseadas em colonialismo português (Ribeiro, 1995). Esses debates se refletem na cultura popular de maneiras particulares; são capturados em formas eruditas de cultura, como literatura, e são então apropriados pela mídia e televisão. As obras de Suassuna podem ser vistas como um recurso valioso deste debate, apontando para questões de assimilação ou segregação de raça e / ou poder de classe, e influência, boa ou ruim, tolerância e preconceito. Observa-se o impacto de seu trabalho não só através da literatura, mas também através dos meios de comunicação. (shrink)

This paper studies the history of teleological thought in Antiquity, after Aristotle, analyzing three relevant episodes: the contribution of Theophrastus – a companion and successor of Aristotle; Stoicism, as described by Cicero in his work On the nature of gods; and Galen’s anatomical and physiological works, especially his book On the utility of the parts of the human body. This analysis exhibits the broad diversity of views concerning final causes in Antiquity, all of them widely different from Aristotle’s one, and (...) the strong influence of theological concerns in some of those philosophers – such as the Stoics and Galen.

Brazilian writer Carolina Maria de Jesus (1914–1977) was born in a rural community and spent most of her life in a slum. Despite this, her literary work achieved remarkable editorial success, having its value recognized by critics and academic circles. This paper analyzes Carolina Maria de Jesus’s autobiographical narratives in the light of John Dewey’s aesthetic theory, with the purpose of investigating the factors responsible for the development of her aesthetic sensitivity – intellectual and emotional dispositions favorable to involvement with (...) artistic practices. The results suggest that Carolina Maria de Jesus’s literary skills, which express not only individual but also collective yearnings, resulted from the incentive she received to think about things that do not exist and from her relationship with people who favored the formation of a personality open to varied experiences. Such results are presented as requirements for a democratic and humanist education that aims at the flowering of aesthetic sensitivity and encourages educators and students to believe in their creative potential.

The Direct Argument argues for the claim that determinism and moral responsibility are incompatible. The most controversial assumption of the argument is the thought that "not being responsible for" transfers across conditionals: if no one is (even partially) morally responsible for the fact that p is true, and no one is (even partially) morally responsible for the fact that p ⸧ q is true, then no one is (even partially) morally responsible for the fact that q is true. Here we (...) argue that the principle is true if one accepts a truth-maker account of the relationship between non-responsibility and propositions. While non-responsibility transfers across conditionals, one upshot of the truth-maker account is that it allows one to be responsible for necessary truths. (shrink)

This paper discusses the role of analogy in pre-theoretical experimental research, studying a particular historical case (the discovery and early investigation of X rays) and using the methodological ideas of William Stanley Jevons. The historical data and Jevons’ analysis suggest that the discovery of a completely new phenomenon is due to chance, but soon afterwards it is necessary that some assumptions provide a guidance to the research – otherwise, observations and experiments would occur at random, and that would sendom lead (...) to significant results. It is impossible to study all the factors that could possibly affect a give phenomenon, and hence the attention of the researcher must focus upon a small number of features. This choice, in a pre-theoretical context, must be guided by analogies. Contrary to tradicional analyses, this paper associates a peculiar epistemological status with analogies used in that kind of investigation: they are interpreted as originating desiderata, instead of probable hypotheses. RESUMO: A partir do estudo de um caso histórico particular (descoberta e investigação preliminar dos raios X), utilizando as concepções metodológicas de William Stanley Jevons, este artigo analisa o papel das analogias no processo de pesquisa experimental pré-teórica. A análise de Jevons e os dados históricos indicam que a descoberta de um fenômeno totalmente novo se dá ao acaso, porém logo em seguida é necessário que algumas suposições guiem a pesquisa, caso contrário as observações e experimentos seriam realizados totalmente ao acaso, o que dificilmente levaria a algum resultado. É impossível estudar todos os fatores que podem influenciar um fenômeno, e assim a atenção do pesquisador deve ser focalizada apenas sobre alguns aspectos, e essa escolha, em um contexto pré-teórico, deve ser guiada por analogias. Ao contrário das análises tradicionais, este artigo atribui um status epistemológico diferente às analogias empregadas nesse tipo de investigação, interpretando-as como geradoras de desiderata e não de hipóteses prováveis.

Abstract This paper describes the early history of magnetochemistry: the search for chemical effects of magnetism in the nineteenth century. Some early researchers, such as Johann Wilhelm Ritter, attempted to reproduce with magnets the effects that had been produced by electricity and Volta’s battery. For several decades, researchers successively reported positive results and denied claims concerning the effect of magnetism in oxidation, electrolysis, reduction of metals from saline solutions, crystallisation, change of colour of vegetable tinctures and other chemical reactions. In (...) the two last decades of the nineteenth century some effects were accepted as real, and a thermodynamic theory of the influence of magnetic fields upon chemical reactions was developed. Finally, Dragomir Hurmuzescu was able to create reproducible experiments and measured the electromotive force between two electrodes, with or without the presence of magnetic fields, confirming the existence of the phenomenon and obtaining results compatible with the theoretical predictions. Afterwards, this magnetochemical effect was accepted as real, but the effect was weak and its practical importance was negligible. The subject was gradually forgotten.

This paper presents an analysis of several experimental tests of Einstein's theories, together with their Popperian evaluation and a discussion of Einstein's reaction to these tests. It is shown that several relevant refutations of Einstein's theories were not accepted by Einstein as significant, and that therefore Einstein did not follow Popper's methodological rules. This is regarded as a strong case against Popper's criterion of demarcation.

O presente ensaio apresenta como ponto de partida o conto "Cadeira", do escritor português José Saramago, para ilustrar a contínua atualidade do estudo "Amizade, recusa do servir" da professora e filósofa Marilena Chaui, publicado em 1982 pela editora Brasiliense como posfácio da obra "Discurso da servidão voluntária", de Étienne de La Boétie. Nossa intenção é partir da alegoria saramaguiana da queda da ditadura salazarista em Portugal para mostrar como o pensamento de La Boétie, especialmente quando analisado por Chaui, trespassa incólume (...) séculos inteiros chegando até a contemporaneidade europeia e brasileira e que possíveis caminhos alternativos a este sistema podem se apresentar.

Neste artigo, pretendo desafiar duas teses que compõem a interpretação padrão da teoria de justiça social de Hume. Primeiro, que esse entendimento não oferece recursos conceituais sufi cientes para se esboçar uma teoria de justiça distributiva e, segundo, que essa teoria é, em princípio, indiferente a ocasionais arranjos sociais fortemente desiguais. Contrariamente, proponho aqui um esboço para uma possível teoria de justiça distributiva em Hume. Argumento, com base em evidência textual, que Hume aborda sistematicamente questões como a distribuição inicial, mudanças (...) na ordem distributiva e, finalmente, ocasionais arranjos redistributivos à luz de princípios que combinam associações imaginativas, considerações de interesse público e intuições utilitaristas.

Democratic decline in various Latin American countries has been accompanied by religious sectors growth. This article aims at interpreting the public presence of Christian churches and their political representatives based on translation as hermeneutical process in which the relationship between religion and public space is observed. Through bibliographical analysis, the text identifies in Ricoeurian translation based hermeneutic applied to religious studies the possibility of interpreting concrete intersubjective and intercontextual translation which are already present in the public space, mainly in two (...) ways: in an intralinguistic dynamics, i.e., the relationship between Christian groups that sufficiently converge onto programmatic actions regarding economic and moral agenda; and in an interlinguistic dimension in the relationship between religious groups and elitist democratic models which constant crisis situation is perhaps beneficial to some sectors. The metaphor of religions as languages also allows the identification of hermeneutic incompatibilities between distinguished theological discourses in the public space, even when they originate from the same tradition. Therefore, translation as hermeneutic process applied to the analysis of religious discourse may become another tool to the field of studies on religion and public space. (shrink)

In his celebrated historic-epistemological work Identité et réalité, Émile Meyerson claimed that the scientific conservation principles were first suggested and accepted for philosophical reasons, and only afterwards were submitted to experimental tests. One of the instances he discussed in his book is the principle of mass conservation in chemical reactions. Meyerson pointed out that several authors, from Antiquity to Kant, accepted the idea of quantitative conservation of matter; and Lavoisier himself was strongly influenced by a priori ideas, using this principle (...) instead of attempting to test it. This paper will review Meyerson’s claim and historic evidence, focusing especially the late nineteenth and early twentieth century, when the principle of mass conservation was tested in highly accurate experiments. Instead of confirming the principle, some of those experiments led to the detection of anomalies. Hans Landolt, for instance, noticed that there were some small violations of the principle. He observed mass variations of about 10−6 in chemical reactions produced in hermetically sealed glass tubes. Since Landolt was a famous chemist, his results produced a strong response. Several researchers repeated his experiments, with different results. Landolt himself improved his experiments, with a balance that could detect mass changes of 10−7. After changes of the experimental procedure, the chemical reactions did not show significant mass changes. There was not, however, any “crucial experiment” “proving” that mass was conserved. The observed anomalies were set aside mainly by theoretical reasons, after the discovery of radioactivity and the development of the theory of relativity. (shrink)

Escrito em 1963, três anos depois do seminário sobre A ética da psicanálise, o texto de Jaques Lacan, Kant com Sade, possibilita férteis discussões a respeito da prática analítica. Quais os limites desta prática? Qual é a razão que a sustenta? A prática analítica é um saber, uma ética ou uma terapêutica? Quais os pressupostos que orientam a sua ação? É evidente que não dispomos de condições necessárias e suficientes para respondermos a tais perguntas no limite de um artigo, tampouco (...) temos a pretensão de fazê-lo. Entretanto, as tomaremos como bússola em busca de pistas sobre a prática analítica lacaniana e o solo em que repousa até a década de 1960. A partir do texto Kant com Sade e do Seminário VII, A ética da psicanálise, ambos escritos por Lacan, buscaremos as semelhanças e diferenças irreconciliáveis entre a lei moral kantiana, a vontade de gozo sadeana e a ética psicanalítica, apontando que é a partir das consequências práticas, efetuadas pelo Marquês de Sade, da aplicação de uma razão pura, tal qual proposta por Kant, que Lacan buscará um novo horizonte para a prática analítica não mais baseada no desejo puro. Nesse sentido, tanto o filósofo alemão Immanuel Kant quanto o escritor francês Marquês de Sade, contemporâneos dos ares da modernidade, expõem um princípio universal pelo qual a ação é valorada. Princípio cuja execução evidencia sua dimensão ética, política e, com Lacan, clínica. Nessa pista, faremos uma discussão a propósito da perversão e da melancolia como limites à prática analítica.

O termo informação ganhou relevância preponderante nas décadas finais do século passado, quando, a explosão informacional, potencializada pelas tecnologias emergentes, fez com que o seu tratamento ganhasse nova dimensão, devido ao seu ritmo cada vez mais crescente. A informação é um elemento fundamental das empresas que procuram a conquista da vantagem competitiva. Para utilizá-la de forma estratégica é importante saber que informações são adequadas, deixar as informações disponíveis e acessíveis, saber as informações relevantes, sua origem e a quem endereça-las e (...) que sua transmissão seja intensa atendendo aos níveis de pertinência desejados. Entretanto, sua utilização pode não receber a devida atenção o que acarretará prejuízos tanto a eficiência quanto à eficácia organizacional.

To use it in a strategically form is important to know what kind of information is suitable, make it available and accessible, know the most relevant information, its origin and to whom address it and its transmission should be intense in view of the desired pertinence levels. Meanwhile, its use might not receive the due attention, what will cause losses in both efficiency and organizational effectiveness. Considering the relevance of the information, the information environments, as well as the importance of information flows for organizations, whether they are public or private, this essay was developed seeking to present, reflect and promote other considerations and works regarding the relationship between the organizational and informational environments. It also presents concepts of mixed organizational and informational environments, as well as its dynamics in organizations. (shrink)

ConclusionThe common assumption that Becquerel had no special reason to study uranium compounds in his search for substances emitting penetrating radiation cannot explain (a) Becquerel's own accounts, which refer to his choice as due to “the peculiar harmonic series of bands”; (b) Becquerel's systematic test of all uranium compounds (and metallic uranium), in contrast to his neglect of other substances; and (c) Becquerel's belief in invisible phosphorescence as an explanation of the radiation emitted by uranium compounds, even after his discovery (...) that non-luminescent and metallic uranium also emit penetrating radiation.By comparing Becquerel's older studies of uranium to his radioactivity research, this paper has presented a reconstruction that can explain all of these points above. According to the historical evidence presented here, it is likely that Becquerel concentrated his attention on uranium and its compounds because the mechanical theory of luminescence opened up the possibility that, precisely in the case of uranium and its compounds, a violation of Stokes's law could occur, and penetrating short-wavelength radiation could be emitted through a special type of phosphorescence.

The work fulfill two purposes. The broad objective is to relativize the division between structuralism and its alleged overcoming or continuation, with post-structuralism. This takes place within a specific procedure: the way in which Saussure develops and precedes importante theses to Deleuze's philosophy of difference. It begins with the critic that Deleuze addresses to the structuralism of the former, as unable to grasp both the differentiation and the organization of the various forms of experience. The focus on Saussure is due (...) to the fact that Deleuze considers him a discoverer of the difference in the realm of language, although he insists on reading it in oppositive and, therefore, negative terms. A “discoverer that covers-up” what he finds, it can be said, that brings to light the differential dynamics of meaning and, at the same time, covers it with the traditional image of thought that is subordinated to identity. Next, it will be clear how this reading does not consider the true positions of the philosophy of language elaborated by Saussure, and that it must be far removed from some of his reputable heirs and followers. The conclusion is that the theory of value focused on the linguistic system precedes the differential theory of the faculties that Deleuze employs to understand each of the structures of our existence.

This work relates L. S. Vygotsky’s theory to the rhetorical and poetic pedagogy, which is a set of educational ideas and practices derived from the philosophical-educational tradition initiated by the Sophists. It is verified that the Vygotskyan concepts contribute to broaden the foundations of poetic and rhetorical pedagogy, presenting a psychology of language that integrates decorum, kairos and antilogical argumentation within aesthetic experiences; communication sustains knowledge and reflection of reality, aiming at the strengthening of the individual’s identity, the education of (...) the creative subject and the improvement of the collective. It is considered that the rhetorical and poetic character of Vygotsky’s theory encourages the contemporary school to be a space for investigation and search for creative solutions, contradicting the measurementist pedagogical tendencies that dehumanize education.
