The acquisition and evolution of speech production, discourse and communication can be negatively impacted by brain malformations. We describe, for the first time, a case of developmental dynamic dysphasia (DDD) in a right-handed adolescent boy (subject D) with cortical malformations involving language-eloquent regions (inferior frontal gyrus) in both the left and the right hemispheres. Language evaluation revealed a markedly reduced verbal output affecting phonemic and semantic fluency, phrase and sentence generation and verbal communication in everyday life. Auditory comprehension, repetition, naming, (...) reading and spelling were relatively preserved, but executive function was impaired. Multimodal neuroimaging showed a malformed cerebral cortex with atypical configuration and placement of white matter tracts bilaterally and abnormal callosal fibers. Dichotic listening showed right hemisphere dominance for language and functional magnetic resonance imaging (fMRI) additionally revealed dissociated hemispheric language representation with right frontal activation for phonology and bilateral dominance for semantic processing. Moreover, subject D also had congenital mirror movements (CMM), defined as involuntary movements of one side of the body that mirror intentional movements of the other side. Transcranial magnetic stimulation and fMRI during voluntary unimanual (left and right) hand movements showed bilateral motor cortex recruitment and tractography revealed a lack of decussation of bilateral corticospinal tracts. Genetic testing aimed to detect mutations that disrupt the development of commissural tracts correlating with CMM (e.g., Germline DCC mutations) was negative. Overall, our findings suggest that DDD in subject D resulted from the underdevelopment of the left inferior frontal gyrus with limited capacity for plastic reorganization by its homologous counterpart in the right hemisphere. Corpus callosum anomalies probably contributed to hinder interhemispheric connectivity necessary to compensate language and communication deficits after left frontal involvement. (shrink)

Political concepts are fundamentally polemical. Their supposed neutrality is solely a vain intellectual supposition. This paper pay attention to the XIX century's Politics through three political concepts: the representation, medieval notion wich the liberal genius transformed to fight the Ancien Régime; the association, socialist and traditionalist alternative to the revolutionary individualism; and finally the participation, based on the originary political community return's myth.

Este artigo objetiva expor e analisar os diferentes sentidos do conceito de verdade delineados por Edmund Husserl na 6ª _Investigação Lógica_. Inicialmente, aborda-se a concepção tradicional de verdade enquanto correspondência em seus aspectos mais fundamentais. A seguir, examina-se como essa ideia de adequação, reinterpretada fenomenologicamente a partir da estrutura intencional do preenchimento, orienta a reflexão husserliana ao conceito de evidência e, por sua vez, como essa análise conduz à tematização do conceito de verdade, uma vez que Husserl define a verdade (...) como o correlato objetivo da evidência. Com isso, chega-se ao núcleo da investigação: procede-se com a caracterização e discussão dos quatro sentidos de verdade elencados por Husserl no parágrafo 39 da 6ª _Investigação Lógica._ Por fim, são apontados alguns aspectos gerais que articulam esses quatro sentidos, com ênfase especial na primazia do sentido de verdade enquanto “ser verdadeiro” em relação aos demais sentidos fenomenológicos apresentados do conceito.

El presente trabajo persigue aclarar y explicitar los fundamentos ontológicos presentes en el tratado Realidad y substancia, de Antonio Escohotado. De modo sintético el sujeto se funda en la nada el recorrido de la esencia, que se redefinirá como invenir para alcanzar el mayor grado de objetividad en el acto, en la actividad de lo real. Al fin, inmerso en una realidad dinámica se postula la vida, ya no como sujeto, para ahondar en la experiencia como un tránsito en el (...) que el conocimiento es posible dentro de lo indeterminado.

La realidad aumentada permite la interacción del usuario con el mundo físico. Esto da la posibilidad de sustituir fantomas por modelos digitales. Se pretende determinar la funcionalidad de implementar tecnología de Realidad aumentada como recurso pedagógico para la asignatura de Anatomía General. Se entregará a los estudiantes una aplicación para teléfono móvil y un cuadernillo con imágenes. Con dicho teléfono visualizarán imágenes que se transformarán en imágenes de realidad aumentada que el estudiante manipulará a través de su teléfono. Los resultados (...) esperados se enfocarán en fomentar la inclusión de modelos de M-LEARNING dentro de la carrera y la Universidad. (shrink)

Charles S. Peirce é considerado o pai do pragmatismo, doutrina filosófica cujo propósito inicial era aliar o conhecimento racional com ação racional. Entretanto, essa doutrina foi amplamente difundida de maneira desvirtuada em sua época, de tal maneira que não havia mais o pragmatismo, mas “pragmatismos”, obrigando o seu criador a manifestar-se contra essa miríade de doutrinas que pouco ou nada tinham haver com a sua doutrina. Dessa manifestação surgiu o artigo O que é o Pragmatismo, publicado em 1905 no periódico (...) filosófico The Monist, no qual ele encerra de vez o termo pragmatismo e passa a adotar o termo pragmaticismo, palavra esta que segundo o autor é “suficientemente feia para estar a salvo de raptores” (CP5.414).

We focus on the debate on the external validity of lab results in the area of experimental economics. More specifically, we focus on Colin Camerer’s and John List’s views, who postulate opposite positions on the issue. The problem is that they partially analyze the same empirical evidence and draw from it opposite conclusions. The goal of this work is to analyze such empirical evidence to try to explain the difference in interpretation of results. We argue that the dispute in interpretations (...) can be expressed in terms of difference of criteria used to determine external validity. From our analysis we propose the formulation of different types of external validity. (shrink)

O objetivo do estudo é analisar a série De onde vem? , a qual introduz o conhecimento científico na infância, identificando aspectos que justifiquem o seu emprego como um recurso pedagógico adequado para a introdução de conceitos de Ciência de forma lúdica e dinâmica na infância. Os resultados apresentam aspectos gerais dos episódios da Série, além da descrição estrutural dos episódios de forma generalizada de acordo com as categorias sugeridas por Gomes (2008). A Série introduz conceitos científicos, presentes no cotidiano, (...) por meio de uma linguagem adequada à compreensão infantil, tornando, assim, este material uma importante alternativa de apoio ao professor do Ensino Fundamental para a introdução da ciência na infância.

Até que ponto temos a obrigação moral de sacrificar nossos interesses pessoais e o nossobem viver para beneficiar outros? Um desafio para qualquer teoria moral é responder a essa pergunta deuma maneira moderada. Uma resposta moderada reconheceria que o agente tem uma obrigação moralde atender às legítimas necessidades alheias, porém não de uma maneira que o impediria de se dedicara projetos e objetivos pessoais que orientam e dão significado à sua vida. O contratualismo moral deThomas Scanlon é defendido por seus (...) proponentes como uma teoria moderada nesse sentido. Oobjetivo deste artigo é avaliar a plausibilidade dessa pretensão. Defenderei que as demandas dabeneficência, sob o contratualismo, parecem impor custos ao agente moral que são mais quemoderados. Concluo sugerindo que isso não deveria ser visto como devastador para o contratualismomoral. (shrink)

Partiendo de las traducciones de las crónicas Iftitah al-Andalus de Ibn al-Qutiyya y Ajbar maymu,a recientemente publicadas por David James, se discuten en profundidad los aspectos historiográficos de ambos textos y la bibliografía sobre el tema.

Actualmente, la discusión sobre los problemas éticos de las nuevas tecnologías suele enfocarse en los dilemas que, de manera concreta y generalmente aislada, supone el uso de unas y otras tecnologías; frente a ello, lo que se propone en este artículo es considerar la problematicidad de nuestro entramado tecnológico, dentro de lo que podemos denominar “nuestra tecnosfera”, para, de ese modo, discutir nuestro presente como un horizonte problemático, en que se redefine el sentido ético de la realidad antropológica. De este (...) modo, y contando como referente teórico la reflexión sobre la técnica de Zubiri y de Ellacuría, proponemos la idea de “hacerse verdaderamente cargo del mundo” como medio para repensar éticamente las nuevas tecnologías (nuestras).

Na presente investigação, objetivou-se analisar, a partir do referencial teórico e metodológico pós-estruturalista, os conceitos de Ciência, Tecnologia e Sociedade na trama com a educação e o ensino de Ciências. Como substrato teórico são utilizadas obras de Michel Foucault, Gilles Deleuze e Felix Guattari, ofertando pistas para ampliar a discussão destes conceitos. Na reunião dos saberes investigados, afirma-se um pensamento científico que desenvolve a produção de sentidos para a educação. Diante do exposto, pensa-se em um ensino, que crie estratégias de (...) existências, que reivindique a trama de teorias e práticas, operando os conteúdos científicos na Sociedade. (shrink)

Este artículo desarrolla un recorrido teórico-crítico por la ontología oscilante de dos medios híbridos: la “novela visual” y la “novela gráfica”. El propósito es dilucidar en qué medida ambas producciones comparten una situación de hermanamiento con otras manifestaciones como la literatura y el cine. Así pues, tomando como caso de estudio estos dos géneros de videojuego y cómic, respectivamente, el presente trabajo aborda las implicaciones derivadas de su ambigüedad definitoria y la dificultad de delinear para ellos parcelas clasificatorias estables. En (...) este contexto es relevante la tensión, presente ya en sus propias nomenclaturas, entre la tendencia hacia el elemento literario-textual y la inclinación hacia el componente de imagen, polaridad alimentada por el debate entre narratividad e interactividad hasta desembocar en el “ensayo gráfico filosófico”.

Luis de Molina was a leading figure in the remarkable sixteenth-century revival of Scholasticism on the Iberian peninsula. Molina is best known for his innovative theory of middle knowledge. Alfred J. Freddoso's extensive introductory essay clears up common misconceptions about Molina's theory, defends it against both philosophical and theological objections, and makes it accessible to contemporary readers.

We analyze the variety of A. Monteiro’s tetravalent modal algebras under the perspective of two logic systems naturally associated to it. Taking profit of the contrapositive implication introduced by A. Figallo and P. Landini, sound and complete Hilbert-style calculi for these logics are presented.

Requiring family authorization for apnea testing subtracts health professionals control over death determination, a procedure that has traditionally been considered a matter of clinical expertise alone. In this commentary, we first provide evidence showing that health professionals’ (HPs) disposition to act on death determination without family’s prior consent could be much lower than that referred to by Berkowitz and Garrett (2020). We hypothesize that HPs may have reservations about their own expertise as regards death, and may thus hesitate to impose (...) their views on patients’ families. We then address the theoretical question of clinical expertise in death determination by distinguishing judgments about facts (e.g., the presence or absence of spontaneous breathing) from interpretations given of these facts (i.e., their meaning for the vital status of an individual). We argue that, while clinicians may claim some expert authority on the former, they hold no particular authority on the latter. (shrink)

A ideia de uma crise do rádio consolidou-se no imaginário coletivo nas últimas décadas, a despeito de não haver ancoragem na realidade. Se muitas rádios tradicionais AM e FM saem do ar, vendidas a igrejas eletrônicas ou novos grupos empresariais, multiplica-se a oferta de conteúdos no contexto de um rádio expandido, que transborda para novas plataformas e é consumido nos mais diversos dispositivos. O rádio vai bem, obrigado, embora algumas emissoras de rádio em ondas hertzianas estejam mal das pernas, lamentando-se (...) da concorrência com serviços on-line e da erosão dos habituais índices de audiência, antes medidos em centenas de milhares de ouvintes por minuto.

Este trabajo examina los diferentes reparos que el recurso a las ideas procedentes de la cultura pública como base de su concepción de la justicia le ha procurado a Rawls. Ese examen se propone establecer dos conclusiones. Primera, frente a quienes sugieren que, con la apelación a tales fundamentos, la solidez del método de justificación que Rawls articula se resiente gravemente y los que esgrimen que, con esa apelación, Rawls renuncia a las pretensiones de universalidad que son consustanciales a la (...) doctrina liberal, intenta poner de manifiesto que el papel que esas ideas cumplen en la justificación de una concepción política de la justicia como la suya únicamente muestra la congruencia que la obra de Rawls exhibe en la manera de entender la naturaleza de la justificación y la clase de elementos sobre los cuales se articula. Segunda, frente a quienes sostienen que el método de justificación empleado por Rawls entraña alguna forma de relativismo o etnocentrismo, trata de evidenciar que ese método no conduce a ese tipo de posiciones, por más que tome como base nuestros juicios considerados y nociones políticas fundamentales.

The Uniform Determination of Death Act (UDDA) provides that “an individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead.” We show that the UDDA contains two conflicting interpretations of the phrase “cessation of functions.” By one interpretation, what matters for the determination of death is the cessation of spontaneous functions only, regardless of their generation by artificial means. By the (...) other, what matters is the cessation of both spontaneous and artificially supported functions. Because each UDDA criterion uses a different interpretation, the law is conceptually inconsistent. A single consistent interpretation would lead to the conclusion that conscious individuals whose respiratory and circulatory functions are artificially supported are actually dead, or that individuals whose brain is entirely and irreversibly destroyed may be alive. We explore solutions to mitigate the inconsistency. (shrink)

We introduce a methodology whereby an arbitrary logic system L can be enriched with temporal features to create a new system T(L). The new system is constructed by combining L with a pure propositional temporal logic T (such as linear temporal logic with Since and Until) in a special way. We refer to this method as adding a temporal dimension to L or just temporalising L. We show that the logic system T(L) preserves several properties of the original temporal logic (...) like soundness, completeness, decidability, conservativeness and separation over linear flows of time. We then focus on the temporalisation of first-order logic, and a comparison is make with other first-order approaches to the handling of time. (shrink)

Au cours de cet entretien, Emmanuel Renault nous offre un aperçu de la manière dont la thématique de la reconnaissance est traitée en France aujourd’hui, notamment à travers le renouveau des études sur Hegel et Marx. Il explique la façon dont la reconnaissance a pu s’ériger en paradigme (en dépit de ses usages multiples et variés en France comme ailleurs), au cours de la dernière décennie et le rôle joué par Axel Honneth dans ce procès. Finalement, il explicite sa manière (...) d’envisager la pratique de la philosophie politique et son projet d’une critique du capitalisme. Emmanuel Renault nous livre également un commentaire critique mais constructif sur la manière dont Paul Ricœur envisage la reconnaissance et suggère quelques pistes concernant les possibles développements futurs des usages de la reconnaissance.

_Ever since Descartes singled out the ability to use natural language appropriately in any given circumstance as the proof_ _that humans – unlike animals and machines – have minds, an idea that Turing transformed into his well-known test to_ _determine whether machines have intelligence, the close connection between language and cognition has been widely_ _acknowledged, although it was accounted for in quite different ways. Recent advances in natural language processing, as_ _well as attempts to create “embodied conversational agents” which couple (...) language processing with that of its natural_ _bodily correlates (gestures, facial expression and gaze direction), in the hope of developing human-computer interfaces_ _based on natural – rather than formal – language, have again brought to the fore the question of how far we can hope_ _machines to be able to master the cognitive abilities required for language use. In this paper, I approach this issue from a_ _different angle, inquiring whether language can be viewed as a “cognitive technology”, employed by humans as a tool_ _for the performance of certain cognitive tasks. I propose a definition of “cognitive technology” that encompasses both_ _external (or “prosthetic”) and internal cognitive devices. A number of parameters in terms of which a typology of_ _cognitive technologies of both kinds can be sketched is also set forth. It is then argued that inquiring about language’s_ _role in cognition allows us to re-frame the traditional debate about the relationship between language and thought, by_ _examining how specific aspects of language actually influence cognition – as an environment, a resource, or a tool. This_ _perspective helps bring together the contributions of the philosophical “linguistic turn” in epistemology and the incipient_ _“epistemology of cognitive technology” It also permits a more precise and fruitful discussion of the question whether, to_ _what extent, and which of the language-based cognitive technologies we naturally use can be emulated by the kinds of_ _technologies presently or in the foreseeable future available.shrink)

En este texto se trata de pensar el proyecto que Foucault inició con el análisis de la parrhesía. Se aborda ese problema en relación a otros dos elementos de su obra: la reflexión sobre la función de los intelectuales y sus escritos sobre la noción de crítica. Desde esa perspectiva trataré de mostrar que las investigaciones sobre la parrhesía reflejan el intento de pensar una nueva política de la verdad.

Do all questions have answers? How much can we know about the world? Is there such a thing as an ultimate truth? To be human is to want to know, to understand our origins and the meaning of our lives. In The Island of Knowledge, physicist Marcelo Gleiser traces our search for answers to the most fundamental questions of existence, the origin of the universe, the nature of reality, and the limits of knowledge. In so doing, he reaches a (...) provocative conclusion: science, the main tool we use to find answers, is fundamentally limited. As science and its philosophical interpretations advance, we are often faced with the unsettling recognition of how much we don't know. Limits to our knowledge of the world arise both from our tools of exploration and from the nature of physical reality: the speed of light, the uncertainty principle, the second law of thermodynamics, the incompleteness theorem, and our own limitations as an intelligent species. Our view of physical reality depends fundamentally on who we are and on how we interact with the cosmos. (shrink)

El artículo contextualiza e investiga los detalles del «Mes de Reflexión Episcopal» organizado por el Departamento de Pastoral de Conjunto del Celam en julio de 1971, que reunió providencialmente varios obispos, algunos de los cuales no estuvieron en la II Conferencia General tres años antes, y que darían testimonio del espíritu de Medellín hasta el martirio o hasta una muerte trágica en cumplimiento de su misión: Oscar Arnulfo Romero, Juan Gerardi Conedera, Gerardo Valencia Cano y Raúl Zambrano Camader. El encuentro (...) se describe a partir de la revisión documental de las actas y de los pocos informes impresos. La tesis central del artículo es que el diálogo informal entre obispos, teólogos y otros expertos en el «Mes de Reflexión Episcopal» es fuente de propuestas novedosas para una Pastoral de Conjunto, contra la clericalización y el autoritarismo en la Iglesia latinoamericana. Desafortunadamente, no hay una reunión posterior similar debido a una controversia con la Congregación romana para los obispos. (shrink)

Suszko's Thesis maintains that many-valued logics do not exist at all. In order to support it, R. Suszko offered a method for providing any structural abstract logic with a complete set of bivaluations. G. Malinowski challenged Suszko's Thesis by constructing a new class of logics (called q-logics by him) for which Suszko's method fails. He argued that the key for logical two-valuedness was the "bivalent" partition of the Lindenbaum bundle associated with all structural abstract logics, while his q-logics were generated (...) by "trivalent" matrices. This paper will show that contrary to these intuitions, logical two-valuedness has more to do with the geometrical properties of the deduction relation of a logical structure than with the algebraic properties embedded on it.

The past decade has seen a flurry of social scientific research on the use of racial categories in human genetics research. This literature has critically analyzed how U.S. race relations are being shaped by and themselves shaping research on human biological difference and disease. Recent work, however, suggests that the particular configurations of science and ethnoracial politics in the US are not exportable. Instead, research on human biology in other contexts reveals the importance of not just racial categories, but national, (...) ethnic, regional and linguistic classifications of bodies and communities...
