O objetivo deste artigo é demonstrar, a partir do pensamento de Marx, como o lucro comercial e a renda fundiária – dois componentes do mais-valor que, juntamente com o salário, correspondem aos rendimentos da fórmula trinitária – pressupõem a exploração do trabalho ou o intercâmbio desigual que mantém o processo de acumulação capitalista. As remunerações do comerciante e do proprietário fundiário, muito embora apareçam na superfície da economia moderna dissociadas do seu fundamento real, como se fossem autônomas e sem qualquer (...) nexo com a espoliação que garante a autovalorização do capital, representam apenas quotas do trabalho excedente obtido na esfera da produção.

A grande incidência de adolescentes com depressão, ideação suicida, tentativa de suicídio e suicídio em todo o mundo vem se apresentando como uma das principais causas de doença e incapacidade. Múltiplos fatores determinam a saúde mental de um estudante. O objetivo desse artigo é descrever os indicadores de depressão, suicídio e habilidades sociais em estudantes do ensino médio no ambiente escolar. O estudo de caso investigou indicadores sobre a depressão, relacionados a habilidades sociais e ideação suicida no contexto escolar. Foi (...) desenvolvido com base na pesquisa social e o tipo de abordagem é fenomenológico, trata-se de uma pesquisa que emprega técnicas quantitativa, qualitativa e descritiva por meio da pesquisa de campo, realizada no ambiente escolar. A coleta de dados foi realizada por meio de questionário socioacadêmico e dois testes psicológicos. Diante dos resultados da pesquisa percebeu-se que 60% da amostra apresentou algum indicador de depressão. Então, foi identificada que quanto menor a frequência dos comportamentos, maior é a dificuldade e menos elaborado é o repertório de habilidades sociais dos adolescentes. Portanto, o ambiente escolar pode ser mais um local para desenvolver as habilidades sociais do estudante e trabalhar com programas de prevenção a depressão e suicídio. (shrink)

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.

Através da análise da trajetória do aquitano Bernardo de Agen, bispo e senhor de Sigüenza entre os anos de 1124 a 1151, discutiremos neste artigo como o processo de reconquista territorial empreendida durante a Idade Média Central foi um dos fundamentos para o exercício da dominação eclesiástica na região de Castela, na Península Ibérica. Munido de um poder específico o qual chamamos de poder senhorial-episcopal, o bispo seguntino despontou como um dos principais nomes inseridos na política castelhano-leonesa, encabeçada por uma (...) gama de interdependências entre a monarquia e os episcopados.

Este artigo parte do entendimento de que a cientificidade na pedagogia exigiu desta área do conhecimento suprimir a experiência como elemento vital da formação do homem, enquanto elevava a comprovação e regularidade do experimento ao patamar de destaque nos seus processos. A partir desta consideração, pretende-se tratar da transformação do conceito de experiência no campo educativo. Inicialmente, abordam-se as questões relacionadas à terminologia e significação do conceito “experiência” e sua possível transformação em “experimento”, e os desdobramentos dessa transição no campo (...) pedagógico. Na sequência, analisa-se a transformação do valor da experiência que passa a ser reconhecida enquanto experimento científico aplicado à pedagogia. Para tanto, apresenta-se, a partir da leitura da literatura educacional especializada, sobretudo os manuais dedicados à formação de professores, como é abordada a temática da Pedagogia Científica, ou seja, a construção dos discursos acerca da modernização da educação por meio de obras que apresentaram expressiva circulação no Brasil durante século XX. Dentre os resultados foi possível apreender o estabelecimento de uma pedagogia do experimento, ou, em outros termos, uma biopsicopedagogia como modelo estruturante do campo teórico da pedagogia com repercussão na formação de professores, e na predominância da problemática do ensino e da aprendizagem, ou seja, a intervenção metodológica em detrimento da formação integral do homem. Por fim, chega-se à conclusão de que se está, de um lado, diante dos impeditivos de realização da experiência e, de outro lado, diante de uma demanda, cada vez mais presente, de romper com o modelo pedagógico da modernidade, rumo aos novos desafios da educação de um homem que não se deixa mais ser, simplesmente, formado.

Do passeio pela filosofia Deleuze-Guattariana ao encontro com o possível conceito de programas de vida Resumo: De todas as maneiras de incursionar uma filosofia, o passeio pareceu ser a abordagem possível diante do emaranhado pensamento de Gilles Deleuze e Félix Guattari. Ainda que alguns se dediquem a localizar onde começa e onde termina a contribuição de cada um nas obras que os dois filósofos escreveram juntos, é nesse entre, no encontro de dois pensadores, que enfrentavam questões específicas em cada campo (...) de ação, mas que foram capazes, por meio da troca, ou melhor do roubo recíproco, como gostava de dizer Deleuze, que se produziu um pensamento que não se acomoda ou se ajusta à tradição. Desse passeio, destaca-se o encontro com um possível conceito presente em diferentes obras desses filósofos que é o programa de vida. Não se trata de um conceito efetivo, pois ele não é alçado a esse status pelos seus autores, ou pelo menos de forma objetiva. Cabe a este artigo, enfim, apresentar um plano sobre o qual esse protoconceito possa ser desenvolvido. Palavras-chave: Programa de vida; Deleuze; Guattari; Intersecção. The stroll of Deleuze-Guattarian philosophy and meeting with the possible concept of life programs: Of all the ways of studying philosophy, the stroll seemed to be the possible approach to the tangled intersected thinking of Gilles Deleuze and Felix Guattari. Although some are dedicated to locating where each one's contribution begins and ends in the works that the two philosophers wrote together, it is in this between, at the meeting of two contemporary thinkers, that they generally faced questions specific to each field of action. That finally, they were able, through an exchange, or rather reciprocal theft, as Deleuze liked to say, that philosophy has been produced which does not fit but is not excluding from what tradition has conventionally called philosophy - reason. This tour highlights the encounter with a possible concept present in different works of these philosophers, which is the program of life. This is not an effective concept, as it is, they not raised to this status by its authors, or at least objectively. It is up to this article, finally, to present a plan on which this developing of concept. Key Works: Life program; Deleuze; Guattari; Intersection. Le promenade par la philosophie Deleuze-Guattarien à la rencontre avec la possible notion de programme de vie De toutes les manières de connaitre une philosophie, le promenade semblait être l’approche possible devant l’enchevêtrement de pensée intersecté de Gilles Deleuze et Félix Guattari. Encore que certain se consacrent a localiser où commence et termine la contribution de chacun dans les oeuvres que les deux philosophes ont écrit ensemble, c’est dans ce entre, la rencontre de deux penseurs contemporains, qui ont généralement confronté les questions spécifiques a chaque champs d’actions, mais qui à la fin, ont été capable, grâce a l’échange, ou mieux du vol réciproque, comme aimait dire Deleuze, que s’est produite une philosophie que ne s’ajustait pas, mais aussi qui ne s’est exclue pas de ce que la tradition convenu a appelé philosophie- la raison. De ce chemin, ce démarque la rencontre avec une possible notion présente dans différentes oeuvres de ces philosophes qui est le programme de la vie. Il ne s’agit pas d’une notion efficace car il n’est élevé pas à ce statut par ses auteurs, ou au moins de forme objectif. Incombe a cet article, enfin, de présenter un plan sur lequel ce ‘proto-notion’ peut être développé.Mots clés : Programme de vie; Deleuze; Guattari; Intersection.

O presente artigo pretende demonstrar como a obra de Maquiavel elenca aspectos pertinentes sobre a relação entre religião e Estado, e como estes podem ser analisados através do ponto de vista da teoria política moderna. Suas contribuições relacionadas ao estudo da função política da religião, entendida como item essencial na manutenção, reconhecimento e solidez do Estado, levantam indagações indispensáveis para pensar a influência de determinados preceitos confessionais, relacionados ao poder eclesiástico, na formulação de uma moral política voltada para a obediência (...) dos ditames de natureza religiosa, e que auxiliam no desenvolvimento de uma vírtu coletiva, elemento, segundo o autor, indispensável para o Estado. O artigo ainda procura explorar questões relacionadas ao método empregado por Maquiavel, e a sua busca pela “verdade efetiva das coisas”. Através desta preocupação, o autor elucida as questões religiosas pela capacidade que as mesmas possuem em influenciar a vida coletiva, influência que abrange as decisões dos cidadãos no que concerne aos temas políticos, garantindo a disciplina e, consequentemente, o fortalecimento do Estado. Assim, o autor de Florença reconhece a incumbência da doutrina religiosa e sua eficiência ao motivar o vivere civile. Palavras-chave: Estado. Religião. Maquiavel. Política. (shrink)

The contribution of Jesuits to the different fields of knowledge, including philosophy, is historically well known. In fact, since the foundation of the Society of Jesus, in the 16th century, Jesuits from different generations and cultures have taken part in the philosophical debates of their time and their different contexts. Since the foundation of the Society of Jesus, in 1540, the Jesuits, individually and as a body, have engaged in a fruitful dialogue between the Christian tradition and different dimensions of (...) human culture. During almost five centuries, numerous Jesuits taught philosophy in academic institutions all over the world. Some of them have their names recorded in the history of philosophy. Of course, the majority of them is not anymore remembered, despite their valuable contribution to the development of the Jesuit intellectual tradition up to our times. In fact, as an heir of the Roman College, the first academic institution founded by the Society of Jesus, in 1551, the Pontifical Gregorian University, in Rome, is a witness to this tradition, which has been kept alive thanks to the discrete work of both Jesuits and lay intellectuals. Known as the University of the Nations, this institution corroborates not only the capacity of the Jesuit tradition to put faith in dialogue with reason, but also the option to take the concrete reality of each human culture and its historical context as its point of departure. The Jesuits’ willingness to engage in dialogue with different intellectual perspectives is underpinned by one of the most defining traits of the Jesuit charism, namely, the conviction that God can be found and served in all things. Accordingly, Jesuits have adopted, from the beginning, an amenable stance towards the world with its different cultures and intellectual trends. As such, Jesuits have, since the beginning, inhabited the frontiers of human thought. According to the contemporary philosopher Paul Gilbert, SJ, within the institutions under the leadership of the Society of Jesus, it was always possible to maintain an equilibrium between two principles: “intellectual unity” and “openness to the world.” Without detriment to the Jesuit identity, the companions of Ignatius have been willing to dwell in the various dimensions of human reality, in their multiplicity and plurality. Either in the renewal of Aristotle’s and Aquinas’ metaphysics, or in the dialogue with modern philosophers such as Descartes, Kant, or Hegel, and even in the inculturation in non-European contexts, the Jesuits have been able to preserve the Christian tradition through an original development of human culture in all its richness and diversity. With respect to the last century, it has to be acknowledged that a significant number of Jesuits made significant contributions, with recognized competence, to philosophy. Certainly, the 20th century was particularly complex in many respects. It would be enough to recall that this period, which brought with it unprecedented social, scientific, and technological developments, was also the stage for the two World Wars. With the emergence or consolidation of philosophical currents such as Marxism, Phenomenology, Existentialism, Structuralism, and Post-Modernism, the past century was, without any doubt, fascinating from the intellectual point of view. Jesuits such as Karl Rahner, Frederick Copleston, Bernard Lonergan, William Norris Clarke, John F. Kavanaugh, Teilhard de Chardin, Gaston Fessard, Jean Daniélou, Henri de Lubac, Michel de Certeau, Xavier Tilliette, Paul Valadier, Paweł Siwek, Ignacio Ellacuría, Francisco Taborda, Henrique de Lima Vaz and, in the Portuguese context, Diamantino Martins or Júlio Fragata, among many others, were able to engage different philosophical currents, problems and controversies of their times. Faithful to their long tradition of being present in the frontiers of thought, those Jesuits have engaged in a fruitful dialogue with these intellectual trends, offering relevant contributions to different ongoing debates. Within this context, the present volume recalls and discusses the philosophical contribution of some of the most prominent Jesuit protagonists of the intellectual interchange that took place in the 20th century. This volume also intends to celebrate the 75th anniversary of the Revista Portuguesa de Filosofia, which happens just before the inauguration of the Ignatian Year. Decreed by Father Arturo Sosa, the Superior General of the Society of Jesus, this celebratory Year will start on May 20, 2021, precisely 500 years after Ignatius of Loyola, the founder of the Jesuit Order, was wounded at the battle of Pamplona. We are happy that this volume could bring together outstanding specialists in the thought of some of the most prominent Jesuits philosophers of the last century, namely Paul Valadier, Paul Gilbert, Józef Bremer, Jacek Poznański, Alexander Maar, Patrick H. Byrne, M. Ross Romero, Carlos Alvarez, Hélio Pereira Lima, José Gama, Domingos Terra, Gabriel Flynn, Marie-Gabrielle Lemaire, José Sols Lucia, Lorena Zuchel Lovera, Pedro Pablo Achondo Moya, Enzo Solari, Massimo Borghesi, Mendo Castro Henriques, João Barbosa, and Dominique Lambert. In addition, in the celebration of the 100th anniversary of Júlio Fragata’s birth, Maria Teresa Fragata presents a memory of his life and thought. We hope that this volume may be useful to all those interested in the Jesuit philosophical tradition. Hopefully, it will stimulate scholars to pursue a fruitful and creative dialogue with contemporary philosophy, in the footsteps of the Jesuit philosophers featured here. We would like to thank all the authors and all those who, in different ways, made this volume possible. (shrink)

In 1948, Bertrand Russell and Frederick Copleston entertained us with a radiophonic debate, on the BBC, concerning the rational proofs of God’s existence. This debate is primarily a product of Authors’ mindset. In this sense, every argument on each side presupposes a universal reason from which human intellect can grasp a certain degree of truth. Therefore, we would expect that the debate 75 years old to be outdated. Or maybe, Russell’s agnostic position could, at first sight, seem to be more (...) aligned with a contemporary post-modern mindset than Copleston’s theism. However, we disagree with the aforementioned thesis. We will not argue that Copleston won the debate by means of reason alone. We will rather show that both positions emerge from different ontologies. And these ones are intertwined with specific narratives and its respective ways of life. For that matter, the Russell-Copleston debate substantiates the thesis of Radical Orthodoxy. Deep down, John Milbank’s “ontology of peace,” as opposed to the Nietzschean nihilism, emerges from this debate. In this sense, while Copleston’s argumentation grounds this narrative on an ontology of peace, Russell tends to follow in a nihilism capable of destroying the communion between different persons. In this sense, the debate is still up to date. (shrink)

The imperative to practice hospitality constitutes a mark of Western civilization. Already in Homer’s Odyssey, the hero Ulysses punishes Polyphemus for not having respected the obligation of hospitality towards him and his companions. In fact, hospitality has been a constitutive element of the West, marked by linguistic, cultural, and religious differences, in a world whose borders are supposed to be well defined. In his discussion of hospitality, Derrida shows how Socrates, in Plato’s dialogue The Apology of Socrates, places himself in (...) the position of a foreigner. In fact, Socrates presents himself as foreigner, that is, someone who is alien to the language and procedures of the court that is judging him. According to Derrida, he shows, in this way, the extent to which the foreigner is forced to ask for hospitality in a language he does not know. The court reduces Socrates to the other, the different. Moreover, the court forces him to deny his difference, his own identity, asking him to adapt himself to a system that he does not control. The paradox arises when Socrates, who regrets being regarded as a foreigner, asks the court to treat him at least as a foreigner. He feels so outraged that he asks to be granted at least the rights of a non-national. In doing so, Socrates shows how recognizing the rights of the foreigner generates hospitality but, at the same time, also limits it. Whenever a human being is recognized as human being, he or she will necessarily be seen as another, as someone different. This person will have to adapt him or herself to a system, culture or world that will define him or her as a foreigner. In short, in the phenomena that we tend to see as hospitality there is always a certain hostility. In a world of ongoing migratory crises, and in the context of a return to nationalisms of exclusion combined with populisms of prejudice and aversion to those who are different, it becomes imperative to rethink the ethics and politics of hospitality. In this context, Derrida’s distinction between conditioned and unconditioned hospitality can be useful. (shrink)

Resumo Este artigo pretende avaliar o papel da imagem na história do atomismo e sua relação com a ideia da visualização do invisível da matéria, com enfoque nas perspectivas epistemológicas de Gaston Bachelard. As origens do atomismo estão ligadas à visão, mas é somente no final do século XVI que a iconografia atomística surge. No artigo, a autora procura evidenciar a tentação humana para o “reino das imagens”: começando por explanar a importância da “metafísica da poeira” ; fazendo notar que (...) o termo “átomo” designou entidades diversas e ressaltando a importância conferida à geometria nas concepções atomísticas, tão presente ao longo da história do atomismo filosófico; tecendo considerações sobre uma das primeiras imagens do átomo - Area Democriti, de Giordano Bruno; colocando em destaque a problemática da imagem no atomismo contemporâneo e do seu radical abstracionismo; explorando o paradoxo da utilidade das imagens a partir de várias obras bachelardianas; mostrando que Bachelard não parece tomar a noção de imagem em sentido lato e que distinguir imagens de não-imagens é supor que ela tenha uma essência e classificação estável; e, por fim, apontando para o fato de cada vez mais a filosofia da ciência tentar apurar qual a função que a iconografia pode ter na criação científica e na transmissão de conhecimento.This article aims to evaluate the role of image in the history of atomism and its relation with the idea of visualization of the invisible of matter, focusing on the epistemological perspectives of Gaston Bachelard. The origins of atomism are linked to vision, but it is only in the late sixteenth century that the atomistic iconography appears. In the article, the author seeks to evince the human temptation to "the realm of images": starting by expounding the importance of the "metaphysics of dust" ; noting that the term "atom" has designated several entities and emphasizing the importance given to geometry in atomistic conceptions, so present throughout the history of philosophical atomism; making considerations about one of the first images of the atom - Area Democriti, of Giordano Bruno; by highlighting the problematics of the image in contemporary atomism and of its radical abstractionism; exploring the paradox of the usefulness of images from various works of Bachelard; showing that Bachelard does not seem to take the concept of image in a broad sense and that to distinguish images of non-images is to assume that it has an essence and stable classification; and, finally, pointing to the fact that increasingly the philosophy of science attempts to investigate what function the iconography may have in scientific creation and transmission of knowledge.

A crise dos modelos de representação fundadas em unidades coerentes e ordenadas parece ter como um dos traços o que Bruno Latour (1993) chamou de “híbridos”(1). Os híbridos são a figura da multiplicidade que não cabe em categorias e que a modernidade “varia para baixo do tapete”. Atualmente, assistimos ao “retorno dos que nunca foram”, que interpelam de forma contundente nossas formas de vida, fortemente apoiadas na técnica. Mas como apreender os fluxos de discursos e práticas mediatizadas que nos (...) atravessam sem cair nas armadilhas do tecnicismo? Que configurações poderiam hoje assumir práticas e discursos críticos? Que agenciamentos propor? Tentar compreender o estatuto do tecnológico, do político, do artístico, do urbano e do banal como “artes do fazer” parece-nos uma tarefa urgente e necessária. Gilles Deleuze (1977), em “Kafka, por uma literatura menor” (2), deixa-nos uma importante pista, ao afirmar, em sua definição de agenciamento, que “a técnica é antes de tudo social”. A direção nos permite avançar para além das concepções instrumentalistas e dicotômicas da técnica e percebê-la enquanto processo complexo de mediação. De fato, como também afirmava Simondon (1989), os objetos técnicos sempre foram gerados por mediação e geradores de mediação(4). O presente número da Revista Logos traz justamente contribuições para fomentar esse debate e para compor o já vasto quadro das cartografias sobre tecnologia e sociabilidade no Brasil, no campo das possibilidades de mediação sociotécnica. Trata-se de um número especial, organizado dentro da parceria PPGC-Uerj e Centre d’Etudes sur l”Actuel et lê Quotidien (CEAQ) - Paris V, com a colaboração do Professor Stéphane Hugon, coordenador do GRETECH, grupo de pesquisa sobre Tecnologia e Quotidiano. Se, por um lado, o conjunto de artigos compartilha determinados referenciais teóricos, por outro, acolhe também visões próprias, forjadas a partir de diferentes experiências sociais e em distintos contextos culturais. Em comum, todos partem de certa forma da percepção de que as mediações presentes nos processos de sociabilidade podem colaborar nos processos de negociação com as regras e códigos sociais vigentes para inventar outros possíveis. Todos, de certa forma, dão a ver, em seu conjunto, que entramos numa arena onde os diversos elementos que constituem o social interagem e ganham novos contornos: o político não dialoga apenas com o “ideológico”, mas também com o cultural, o subjetivo, o artístico. Da mesma forma, a arte, por exemplo, não diz respeito apenas ao cânone, mas também ao político, ao urbano, ao sensual e ao banal. Com isso, também a noção de tecnologia se amplia e, entendida como “máquina social”, pode ajudar-nos a melhor apreender as dimensões dos fenômenos culturais e de comunicação hoje. Os onze textos reunidos neste número apontam exatamente para o momento singular em que vivemos sob alguns de seus mais diversos ângulos. Stéphane Hugon da Universidade René Decartes-Paris V/CEAQ discute a importância dos processos de apropriação da tecnologia no quotidiano; João Maia e Eduardo Bianchi, da UERJ, abordam a sociabilidade de jovens adolescentes de uma favela carioca como forma criativa de cidadania; Vicenzo Susca, da Universidade René Decartes-Paris V e da Università di Lingue e Comunicazione de Milão, aborda o aspecto subversivo das tecnologias, através de uma perspectiva transpolítica; Beatriz Bretas da UFMG apresenta estudos de caso sobre modos de organização de redes sociais virtuais no Brasil; Fabio Larocca discute como as tecnologias alteram nosso olhar sobre as dinâmicas sócio-espaciais no contexto das cidades; Florian Dauphin faz uma análise do sofware livre na França, país com uma das mais fortes tradições de organização social desse movimento na Europa; José Pinheiro Neves, da Universidade do Minho, recupera a contribuição de Simondon para uma análise da percepção das imagens nas telas dos computadores; Shangsub Choi, do Korea Information Society Development Institute, aborda as mudanças propiciadas pela internet no quotidiano de pessoas e empresas e as possibilidades de contra-poder; a arquiteta e urbanista Julieta Leite aposta na integração das tecnologias digitais aos tecidos da cidade para a construção de novas experiências espaciais coletivas; Maria da Luz Correia analisa a recuperação da comunicação por cartões postais nos dias atuais. Finalmente, Hedi Zamouri faz uma etnografia da Brigada Anti-Pub, movimento contra o abuso da publicidade nos espaços públicos de Paris e José Cláudio Castanheira resenha o último livro de Shetyl Turkle, “História íntima dos objetos”. A Logos 29, edição especial, chega assim aos leitores com uma gama variada de proposições e de lugares de observação, brindando-nos com novas pistas para a análise de questões que compõem a pesquisa atual no campo da comunicação. Desejamos a todos uma boa leitura. Fernando Gonçalves Editor temático desta edição especial da Logos.

Com este fito, pretendemos diferenciar os resultados objetivos do ódio, raiva e culpa, bem como o modo que as (...) agressões invisíveis repercutem na vida do oprimido. Tendo como foco o racismo na vida da “mulher de cor” que ainda nos dias de hoje, em uma pirâmide social, se encontram em desvantagem quanto aos demais indivíduos. Faz parte dos objetivos também trazer à tona a reação do oprimido como consequência natural dos séculos de silenciamento, privação e desumanização, analisando os mecanismos institucionais para pacificação social.

Carnival was brought to the New World by Spanish and Portuguese colonizers, and it has been preserved there up to our day, although in the meantime it has almost disappeared from the countries where it originated. One asks oneself if Carnival has kept its original characteristics over the years, or if it instead has been transformed, and if so, how. The ethnological and cultural variety present in Latin America leads us to think that there must have been an evolution over (...) the years, and that Carnival should show some signs of acculturation. It is the examination of these two points that will be the subject of our study. (shrink)

Rio de Janeiro, the opening of the carnival. On the Friday evening preceding Mardi Gras, the mayor of Rio hands over the keys to the city to King Momo, sovereign of the carnival. Immediately the samba breaks out in the brightly lit streets of the city. Newspapers, magazines and television feature big headlines describing the event and glorifying the holiday kingdom. They all report that the city is being shaken by winds of madness, that licence and inversions of every variety (...) are rampant, that the leveling of individuals and the abolition of social distances illustrate the resolutions of conflicts in a collective dream of joy and happiness….

ABSTRACT This article aims to defend the dialogical nature of the landscape. Working in between the borders of the Bakhtinian philosophy of language and cultural studies on landscape, we defend that landscape study should not be studied without considering the cultural forms of communication in the different domains of social organization– the speech genres; that landscape is a semiotic encounter with a concrete otherness; that the interpreter who emerges when an area enters a relationship of representation is necessarily characterized as (...) a chronotope; that every landscape is a chronotopic representation; that cultural geography recognizes that the semiotic aspects of the landscape are as material as its morphology. We start from the hypothesis that landscape is a chronotopic representation that is always made possible by means of some speech genre, because it is always a communicative process, and an encounter with another in a situation of socially organized interrelation – it is concrete dialogue. To find the deeper meaning of a landscape, one must recognize and understand its material, historical, geographical, and dialogic nature. RESUMO O artigo objetiva defender a índole dialógica da paisagem. Trabalhando na fronteira entre a filosofia bakhtiniana da linguagem e os estudos culturais da paisagem, defendemos que a paisagem não seja estudada sem considerar as formas culturais de comunicação nos diferentes domínios da organização social – os gêneros discursivos; que toda paisagem é encontro semiótico com uma alteridade concreta; que o intérprete que emerge quando uma área entra em relação de representação é necessariamente caracterizado por um cronotopo; que toda paisagem é representação cronotópica; que a geografia cultural reconheça que os aspectos semióticos da paisagem são tão materiais quanto sua morfologia. Partimos da hipótese de que a paisagem é uma representação cronotópica que sempre se realiza através de algum gênero discursivo, pois sempre é um processo comunicativo e de encontro com o outro em uma situação de inter-relação socialmente organizada – é diálogo concreto. Para adentrar à profundeza de seus sentidos, precisa-se reconhecer e compreender sua índole material, histórica, geográfica e dialógica. (shrink)

The lambda calculus is a universal programming language. It can represent the computable functions, and such offers a formal counterpart to the point of view of functions as rules. Terms represent functions and this allows for the application of a term/function to any other term/function, including itself. The calculus can be seen as a formal theory with certain pre-established axioms and inference rules, which can be interpreted by models. Dana Scott proposed the first non-trivial model of the extensional lambda calculus, (...) known as $ D_{\infty }$, to represent the $\lambda $-terms as the typical functions of set theory, where it is not allowed to apply a function to itself. Here we propose a construction of an $\infty $-groupoid from any lambda model endowed with a topology. We apply this construction for the particular case $D_{\infty }$, and we see that the Scott topology does not provide enough information about the relationship between higher homotopies. This motivates a new line of research focused on the exploration of $\lambda $-models with the structure of a non-trivial $\infty $-groupoid to generalize the proofs of term conversion to higher-proofs in $\lambda $-calculus. (shrink)

An appropriate framework is put forward for the construction of $$\lambda $$ -models with $$\infty $$ -groupoid structure, which we call homotopic $$\lambda $$ -models, through the use of an $$\infty $$ -category with cartesian closure and enough points. With this, we establish the start of a project of generalization of Domain Theory and $$\lambda $$ -calculus, in the sense that the concept of proof (path) of equality of $$\lambda $$ -terms is raised to higher proof (homotopy).

The intention here is that of giving a formal underpinning to the idea of 'meaning-is-use' which, even if based on proofs, it is rather different from proof-theoretic semantics as in the Dummett-Prawitz tradition. Instead, it is based on the idea that the meaning of logical constants are given by the explanation of immediate consequences, which in formalistic terms means the effect of elimination rules on the result of introduction rules, i. e. the so-called reduction rules. For that we suggest an (...) extension to the Curry-Howard interpretation which draws on the idea of labelled deduction, and brings back Frege's device of variable-abstraction to operate on the labels (i. e., proof-terms) alongside formulas of predicate logic. (shrink)

One takes advantage of some basic properties of every homotopic \(\lambda\)-model (e.g. extensional Kan complex) to explore the higher \(\beta\eta\)-conversions, which would correspond to proofs of equality between terms of a theory of equality of any extensional Kan complex. Besides, Identity types based on computational paths are adapted to a type-free theory with higher \(\lambda\)-terms, whose equality rules would be contained in the theory of any \(\lambda\)-homotopic model.

Taxonomies of living things and the methods used to produce them changed little with the institutionalization of evolutionary thinking in biology. Instead, the relationships expressed in existing taxonomies were merely reinterpreted as the result of evolution, and evolutionary concepts were developed to justify existing methods. I argue that the delay of the Darwinian Revolution in biological taxonomy has resulted partly from a failure to distinguish between two fundamentally different ways of ordering identified by Griffiths : classification and systematization. Classification consists (...) of ordering entities into classes, groups defined by the attributes of their members; in contrast, systematization consists of ordering entities into systems, more inclusive entities whose existence depends on some natural process through which their parts are related. Evolutionary, or phylogenetic, systematics takes evolutionary descent to be the natural process of interest in biological taxonomy. I outline a general framework for a truly phylogenetic systematics and examine some of its consequences. (shrink)

An examination of the post-Darwinian history of biological taxonomy reveals an implicit assumption that the definitions of taxon names consist of lists of organismal traits. That assumption represents a failure to grant the concept of evolution a central role in taxonomy, and it causes conflicts between traditional methods of defining taxon names and evolutionary concepts of taxa. Phylogenetic definitions of taxon names (de Queiroz and Gauthier 1990) grant the concept of common ancestry a central role in the definitions of (...) taxon names and thus constitute an important step in the development of phylogenetic taxonomy. By treating phylogenetic relationships rather than organismal traits as necessary and sufficient properties, phylogenetic definitions remove conflicts between the definitions of taxon names and evolutionary concepts of taxa. The general method of definition represented by phylogenetic definitions of clade names can be applied to the names of other kinds of composite wholes, including populations and biological species. That the names of individuals (composite wholes) can be defined in terms of necessary and sufficient properties provides the foundation for a synthesis of seemingly incompatible positions held by contemporary individualists and essentialists concerning the nature of taxa and the definitions of taxon names.

At least three different issues are commonly referred to by the term “the species problem”: one concerns the necessary properties of species, a second the processes responsible for the existence of species, and a third methods for inferring species limits. Solutions have recently been proposed to the first two problems, which are conceptual in nature (the third is methodological). The first equates species with metapopulation lineages and proposes that existence as a separately evolving metapopulation lineage be considered the only necessary (...) property of species. The second views the species category as a cluster concept and proposes that no single process or set of processes be considered necessary for the existence of species. Although these two solutions have been portrayed as being in conflict, they are, in fact, highly compatible. Moreover, the proposals in question clarify the problem concerning methods for inferring the limits of species, which has for a long time been confused with the problem concerning the necessary properties of species. Together these proposals provide the opportunity for biology to move beyond debates about the definition of the species category and focus on estimating the boundaries and numbers of species as well as studying the diverse processes involved in their origin and persistence.

Ernst Mayr played a central role in the establishment of the general concept of species as metapopulation lineages, and he is the author of one of the most popular of the numerous alternative definitions of the species category. Reconciliation of incompatible species definitions and the development of a unified species concept require rejecting the interpretation of various contingent properties of metapopulation lineages, including intrinsic reproductive isolation in Mayr's definition, as necessary properties of species. On the other hand, the general concept (...) of species as metapopulation lineages advocated by Mayr forms the foundation of this reconciliation, which follows from a corollary of that concept also advocated by Mayr: the proposition that the species is a fundamental category of biological organization. Although the general metapopulation lineage species concept and Mayr's popular species definition are commonly confused under the name "the biological species concept," they are more or less clearly distinguished in Mayr's early writings on the subject. Virtually all modern concepts and definitions of the species category, not only those that require intrinsic reproductive isolation, are to be considered biological according to the criterion proposed by Mayr. Definitions of the species category that identify a particular contingent property of metapopulation lineages (including intrinsic reproductive isolation) as a necessary property of species reduce the number of metapopulation lineages that are to be recognized taxonomically as species, but they cause conflicts among alternative species definitions and compromise the status of the species as a basic category of biological organization.

SummaryLooking at proof theory as an attempt to ‘code’ the general pattern of the logical steps of a mathematical proof, the question of what kind of rules can make the meaning of a logical connective completely explicit does not seem to have been answered satisfactorily. The lambda calculus seems to have been more coherent simply because the use of ‘λ’ together with its projection 'apply' is specified by what can be called a 'reduction' rule: β‐conversion. We attempt to analyse the (...) role of proof rules, making use of a set of formal rules designed to capture both the notions of proof theory and those of the lambda‐calculus: Martin‐Löf's Intuitionistic Type Theory.RésuméSi on considère la théorie de la démonstration comme une tentative de ‘codifier’ les pas logiques d'une démonstration mathématique, on se rendra compte qu'on n'a pas répondu de façon satisfaisante à la question suivante: quelles sont les règies qui rendent complètement explicite le sens d'un connecteur logique? Le lambda‐calcul a été apparemment plus cohérent, tout simplement parce que l'utilisation du‘λ’ avec sa projection 'apply' est spécifiée par une regie de 'réduction': β‐conversion. Nous essayons d'analyser le rôle des règies de démonstration, en utilisant un système formel de règies conçu pour englober à la fois les notions de la théorie de la démonstration et celles du lambda‐calcul: la Théorie Intuitionniste des Types de Martin‐Löf.ZusammenfassungWenn man Beweistheorie als einen Versuch, ein allgemeines Muster der logischen Schritte in einem mathematischen Beweis zu kodifizieren, betrachtet, so scheint die Frage nach der Art von Regeln , die die Bedeutung von logischen Operatoren vollständig beschreiben, nicht zufriedenstellend beantwortet. Der Lambda‐Kalkül erscheint, kohärenter, einfach deshalb weil der Gebrauch von ‘λ’ zusammen mit dessen Projektion 'apply' durch Regeln bestimmt wird, die man 'Reduktions'‐Regeln nennen kann: β‐Konversion. Wir versuchen, die Rolle von Beweisregeln zu analysieren, indem wir ein Regelsystem verwenden, das sowohl die Begriffe der Beweistheorie als auch diejenigen des Lambda‐Kalküls erfasst, nämlich die Martin‐Löfsche Typentheorie.

Since the end of the 19th century, Brazilian researchers have speculated about the phenomenon of ethnic coexistence they have witnessed in their country. How may the mixed culture that is its obvious result be explained? Should it be attributed to some sociocultural syncretism, to an interpenetration of civilizations or, quite simply, to a synthesis? Whatever the case, it is certain that cultural elements of very different origins became united in Brazil and that they have remained closely associated there in spite (...) of their disparity. The best example of this “cultural conglomerate,” if we may call it that, is without a doubt that of the Afro-Brazilian religious cults and, although numerous studies have already been devoted to them, they have a richness of content and meaning, plus a capacity for renewal, that is far from being exhaustively investigated.
