RESUMO O objetivo deste artigo é problematizar algumas linhas de força da argumentação de Dominique Maingueneau sobre a constituição de um dispositivo teórico e metodológico para o estudo da literatura na perspectiva discursiva. Para isso, partimos do cotejamento de suas teses com pressupostos fundadores da análise do discurso de tradição francesa e com proposições coetâneas dos estudos literários. Se, por um lado, a proposta de Maingueneau figura como uma sistematização importante de concepções norteadoras de uma análise do discurso literário, por (...) outro, posiciona-se lateralmente quanto à necessidade de consideração epistemológica pela especificidade do discurso literário, gerando o risco da descaracterização histórica e social da literatura. ABSTRACT This paper aims to problematize some of Dominique Maingueneau’s lines of argument about the constitution of a theoretical and methodological device to study literature from a discursive perspective. To this end, we drew from the comparison of his theses using founding assumptions of French discourse analysis and contemporary propositions of literary studies. On the one hand, Maingueneau’s proposal represents an important systematization of guiding conceptions regarding the literary discourse. On the other hand, it is neutral concerning the need for an epistemological consideration given the specificity of literary discourse. Therefore, it risks a historical and social mischaracterization of literature. (shrink)

For decision making in government, it is necessary to have well-structured sources of information. In several countries, it is difficult to access government data as the information are dispersed, disconnected, and poorly structured. For this reason, this work presents a framework to gather, unify, and enrich missing person data from distributed web sources. The framework allows inserting new tasks specific to the user’s domain to improve data quality. In this study, Brazilian missing person data from non-governmental organizations (NGOs) and governmental (...) websites were collected and semantically enriched. To enhance the understanding of the gathered missing people cases, we create interpretive models using machine learning techniques to extract knowledge and to encourage the use of standards for publishing the data that are frequently ignored by organizations, hindering analysis and decision-making on data. After the collection and semantic enrichment process, there was an increase of approximately 11% in the data present in the base. Also, the mining process evidenced the disappearance and reappearance of a person in Brazil according to several factors such as age, state initiatives, skin tone, hair colors, etc. (shrink)

Cet ouvrage s'inscrit dans le fil du travail collectif entrepris en 1995, l'Histoire de la pensée médicale en Occident (trois volumes sous la direction de Mirko D Grmek, Seuil, 1995, 1997, 1999). Il rend compte du déploiement des recherches pluridisciplinaires et transdisciplinaires de la pensée médicale et aborde les discussions et controverses actuelles sur les politiques de santé. Du fait du développement des connaissances théoriques et des innovations techniques, la notion même de soin, sous ses aspects sociaux, économiques, mais aussi (...) épistémiques, se trouve questionnée. La pensée médicale ne saurait se limiter aux données biologiques, et ses composantes spécifiquement humaines et sociales sont explorées et interrogées ici dans une perspective historique qui tient compte des découvertes du dernier siècle.

There is a clear tendency in contemporary political/legal thought to limit agency to individual agents, thereby denying the existence and relevance of collective moral agency in general, and corporate agency in particular. This tendency is ultimately rooted in two particular forms of individualism – methodological and fictive (abstract) – which have their source in the Enlightenment. Furthermore, the dominant notion of moral agency owes a lot to Kant whose moral/legal philosophy is grounded exclusively on abstract reason and personal autonomy, to (...) the detriment of a due recognition of the socio-historical grounds of moral social conduct.I shall argue that an adequate theory of responsibility is needed, which does not only take into account individual responsibility, but also collective and corporate responsibility, capable of taking into consideration society and its problems. Furthermore, corporations are consciously and carefully structured organisations with different levels of management and have clearly defined aims and objectives, a central feature upon which I shall be focussing in this paper.

Let M be a smooth, compact manifold of dimension n ≥ 5 and sectional curvature | K | ≤ 1. Let Met (M) = Riem(M)/Diff(M) be the space of Riemannian metrics on M modulo isometries. Nabutovsky and Weinberger studied the connected components of sublevel sets (and local minima) for certain functions on Met (M) such as the diameter. They showed that for every Turing machine T e , e ∈ ω, there is a sequence (uniformly effective in e) of homology (...) n-spheres {P k e } k ∈ ω which are also hypersurfaces, such that P k e is diffeomorphic to the standard n-sphere S n (denoted P k e ≈ diff S n ) iff T e halts on input k, and in this case the connected sum N k e =M ♯ P k e ≈ diff M , so N k e ∈ Met(M), and N k e is associated with a local minimum of the diameter function on Met(M) whose depth is roughly equal to the settling time σ e (k) of T e on inputs y i } ∈ ω of c.e. sets so that for all i the settling time of the associated Turing machine for A i dominates that for A i + 1 , even when the latter is composed with an arbitrary computable function. From this, Nabutovsky and Weinberger showed that the basins exhibit a "fractal" like behavior with extremely big basins, and very much smaller basins coming off them, and so on. This reveals what Nabutovsky and Weinberger describe in their paper on fractals as "the astonishing richness of the space of Riemannian metrics on a smooth manifold, up to reparametrization." From the point of view of logic and computability, the Nabutovsky-Weinberger results are especially interesting because: (1) they use c.e. sets to prove structural complexity of the geometry and topology, not merely undecidability results as in the word problem for groups, Hilbert's Tenth Problem, or most other applications; (2) they use nontrivial information about c.e. sets, the Soare sequence {A i } i ∈ ω above, not merely G öodel's c.e. noncomputable set K of the 1930's; and (3) without using computability theory there is no known proof that local minima exist even for simple manifolds like the torus T 5 (see §).

O que Foucault entende por jornalismo e como ele se relaciona com a filosofia? Para responder à questão, escrutinamos declarações do autor francês acerca do assunto, especialmente sobre dois personagens: Nietzsche “o primeiro filósofo-jornalista” e Kant “o responsável por introduzir o hoje na filosofia”. Detalhando nuances, pretendemos mostrar em que o pensamento de Foucault se avizinha de um jornalismo radical, e em que deste ele se diferencia.

Este artigo tem como objetivo estabelecer as relações entre as habilidades sociais e as vivências acadêmicas necessárias à adaptação ao contexto universitário. A pesquisa foi realizada com 200 estudantes do curso de Psicologia de instituições públicas e privadas. Os dois instrumentos utilizados (IHS-Del Prette, 2001 e QVA de Villar, 2003) foram aplicados em conjunto em consonância com as normas do QVA. Os resultados permitem aÞ rmar que os alunos de instituições públicas apresentam melhor adaptação acadêmica do que os de instituições (...) privadas. Foram encontradas correlações entre adaptação acadêmica e habilidades sociais. Para os alunos de instituições públicas as habilidades sociais se relacionam principalmente com as dimensões pessoal e contextual e para os de instituições particulares, com a dimensão de realização.

O NEOCONSTITUCIONALISMO E A CONCRETIZAÇÃO DA DIGNIDADE DA PESSOA IDOSA.

O presente artigo tem como objetivo analisar a interpretação de Popper acerca de um suposto antiteoricismo, que se manifesta na ideia de purificação da mente e na defesa da observação como ponto inicial da ciência, em Francis Bacon. Popper considera que tal posição antiteórica, a que deu o nome de “observacionismo”, supervaloriza o papel da observação no método científico. Procuramos discutir se Bacon realmente assume tal posição e em quais circunstâncias a leitura popperiana é possível. Nossa hipótese é de que (...) o filósofo inglês não pode ser considerado um antiteoricista e, portanto, um defensor do empirismo ingênuo. Dessa maneira, iremos expor a posição de Popper e depois contestá-la com auxílio de comentadores especializados na teoria baconiana. (shrink)

We begin with the history of the discovery of computability in the 1930’s, the roles of Gödel, Church, and Turing, and the formalisms of recursive functions and Turing automatic machines . To whom did Gödel credit the definition of a computable function? We present Turing’s notion [1939, §4] of an oracle machine and Post’s development of it in [1944, §11], [1948], and finally Kleene-Post [1954] into its present form. A number of topics arose from Turing functionals including continuous functionals on (...) Cantor space and online computations. Almost all the results in theoretical computability use relative reducibility and o-machines rather than a-machines and most computing processes in the real world are potentially online or interactive. Therefore, we argue that Turing o-machines, relative computability, and online computing are the most important concepts in the subject, more so than Turing a-machines and standard computable functions since they are special cases of the former and are presented first only for pedagogical clarity to beginning students. At the end in §10–§13 we consider three displacements in computability theory, and the historical reasons they occurred. Several brief conclusions are drawn in §14. (shrink)

Here we study polysemy as a potential learning bias in vocabulary learning in children. Words of low polysemy could be preferred as they reduce the disambiguation effort for the listener. However, such preference could be a side-effect of another bias: the preference of children for nouns in combination with the lower polysemy of nouns with respect to other part-of-speech categories. Our results show that mean polysemy in children increases over time in two phases, i.e. a fast growth till the 31st (...) month followed by a slower tendency towards adult speech. In contrast, this evolution is not found in adults interacting with children. This suggests that children have a preference for non-polysemous words in their early stages of vocabulary acquisition. Interestingly, the evolutionary pattern described above weakens when controlling for syntactic category (noun, verb, adjective or adverb) but it does not disappear completely, suggesting that it could result from a combination of a standalone bias for low polysemy and a preference for nouns.

In [2] we constructed an infinite set of natural numbers containing no subset of higher (Turing) degree. Since it is well known that there are nonrecursive sets (e.g. sets of minimal degree) containing no nonrecursive subset of lower degree, it is natural to suppose that these arguments may be combined, but this is false. We prove that every infinite set must contain a nonrecursive subset of either higher or lower degree.

Este ensaio possui o objetivo de problematizar os limites da interpretação a partir de três concepções de língua e suas repercussões nesse processo, cujo desembocar dá-se justamente nos meandros da produção de sentidos. Para explicar isso, é feito o rastreamento, não só das noções de língua, mas também de algumas teorias do discurso, que se voltam, por meio de seus instrumentais analíticos, para a compreensão dos objetos simbólicos circulantes no circuito social, como o texto, por exemplo. Além da crítica ao (...) esgarçamento da interpretação, verificou-se, mediante ao edifício argumentativo construído ao longo do ensaio, que fake news são fruto das interpretações, ancoradas na interatividade dinâmica da língua, abertas pela operacionalidade dos usos da noção contemporânea de discurso e seus efeitos adjacentes.

Chemical embryology was born in 1931 with the publication of Chemical Embryology by Joseph Needham. In the following two decades it became an innovative research project aiming at the description of the construction of the embryological structure and differentiation in biochemical terms. This research programme produced a vast amount of experimental evidence and theories on the chemical dynamics of the embryo: particularly chemical characterization of the zygote and the developing embryo, the chemical exchanges between the nucleus and the cytoplasm, the (...) significance of subcellular structures, and the role and distribution of nucleic acids within the cell. From the 1950s on, a large part of these results came to be integrated into the empirical basis of molecular biology. However, the shift from chemical embryology to molecular embryology was not just a semantic shift but a deep theoretical change, produced by the introduction of a new model of scientific explanation, based on the transmission and expression of genetic information and opposed to the biochemical definition of life.

From its first proposal, the Central Dogma had a graphical form, complete with arrows of different types, and this form quickly became its standard presentation. In different scientific contexts, arrows have different meanings and in this particular case the arrows indicated the flow of information among different macromolecules. A deeper analysis illustrates that the arrows also imply a causal statement, directly connected to the causal role of genetic information. The author suggests a distinction between two different kinds of causal links, (...) defined as 'physical causality' and 'biological determination', both implied in the production of biological specificity.

Com o rápido desenvolvimento da técnica e da tecnologia, o campo educacional tem se mostrado estratégico para transformar a racionalidade humana em racionalidade tecnológica, alterando a consecução dos fins da própria Educação. O objetivo do artigo é analisar as contradições entre o processo de reprodução da vida material nas sociedades capitalistas e a perda de liberdade dos indivíduos inseridos e ajustados aos seus critérios e, da mesma forma, o ajustamento dos estudantes às demandas socialmente úteis ao sistema em decorrência da (...) pretensa extinção dos cursos de Ciências Humanas dos currículos, que tende a afastar a Educação de sua prerrogativa fundamental que é educar para a emancipação. A Teoria Crítica do filósofo frankfurtiano Herbert Marcuse refere que o restabelecimento da razão humana é tarefa para uma Pedagogia Radical como forma de resistência em tempos de mercantilização da Educação. Seus argumentos contribuem para uma análise crítica e contextualizada da Educação brasileira em tempos de contrarreformas. (shrink)

We consider the informal concept of "computability" or "effective calculability" and two of the formalisms commonly used to define it, "(Turing) computability" and "(general) recursiveness". We consider their origin, exact technical definition, concepts, history, general English meanings, how they became fixed in their present roles, how they were first and are now used, their impact on nonspecialists, how their use will affect the future content of the subject of computability theory, and its connection to other related areas. After a careful (...) historical and conceptual analysis of computability and recursion we make several recommendations in section §7 about preserving the intensional differences between the concepts of "computability" and "recursion." Specifically we recommend that: the term "recursive" should no longer carry the additional meaning of "computable" or "decidable;" functions defined using Turing machines, register machines, or their variants should be called "computable" rather than "recursive;" we should distinguish the intensional difference between Church's Thesis and Turing's Thesis, and use the latter particularly in dealing with mechanistic questions; the name of the subject should be "Computability Theory" or simply Computability rather than "Recursive Function Theory.".

Este texto quer examinar como Kant a partir da sua concepção de _cogito_ procura refutar o idealismo problemático de Descartes. Em primeiro lugar, quer verificar se Kant, ao entender a consciência de si como dependente da consciência de objeto, não estaria assumindo pressupostos metafísicos e epistemológicos diferentes dos assumidos por Descartes em sua concepção de _cogito_. Em segundo lugar, tenta formular o problema do alcance das noções de representação e reflexividade em cada um dos referidos filósofos. Para enfrentar essa problemática, (...) elege como metodologia de investigação a análise da Refutação do Idealismo da Analítica dos Princípios da _Crítica da Razão Pura_, bem como de alguns textos de Descartes que explicitam a sua concepção de _cogito_.
