In the Schrödinger equation, time plays a special role as an external parameter. We show that in an enlarged system where the time variable denotes an additional degree of freedom, solutions of the Schrödinger equation give rise to weights on the enlarged algebra of observables. States in the associated GNS representation correspond to states on the original algebra composed with a completely positive unit preserving map. Application of this map to the functions of the time operator on the large system (...) delivers the positive operator valued maps which were previously proposed by two of us as time observables. As an example we discuss the application of this formalism to the Wheeler-DeWitt theory of a scalar field on a Robertson-Walker spacetime. (shrink)

Le droit applicable à l’exercice de l’autorité parentale a été remanié par la loi du 4 mars 2002. Il existe désormais un statut légal du couple parental, applicable quelle que soit la situation familiale des parents, conditionné par l’établissement du lien de filiation de l’enfant. Ce droit commun est gouverné par un principe supérieur : les père et mère exercent en commun l’autorité parentale. La consécration progressive d’un principe d’autorité parentale conjointe (1970,1987,1993, 2002) est certes un progrès en ce qu’elle (...) invite les parents à s’accorder et à se consulter dans l’exercice de l’autorité parentale, mais l’indifférenciation des situations familiales sur laquelle repose désormais la notion de « coparentalité » est excessive en ce qu’elle conduit à détacher le principe du modèle d’un couple uni. Une autre orientation pourrait être prise : celle consistant à rapprocher du mariage le concubinage avec vie maritale, ce qui supposerait de prendre en la matière le contre-pied de la loi de 1999. L’apport le plus apparent de la loi du 4 mars 2002 est de prévoir tout un arsenal de dispositions de nature à assurer l’effectivité du principe de coparentalité, en particulier les conventions et la résidence alternée. Les conventions marquent, sous l’angle de la notion d’ordre public, l’avènement du pluralisme familial, nouveauté encadrée par un corps de règles de plus en plus tentaculaire. Quant à la résidence alternée, cette modalité présente le défaut majeur d’être désormais légale, ce qui implique sa vocation à s’appliquer à tous. Il serait souhaitable pour cette raison de rétablir dans la loi le principe de la résidence habituelle de l’enfant chez l’un de ses parents et de réserver la résidence alternée à la pratique judiciaire, à titre très exceptionnel et expérimental, pour des enfants en âge de l’assumer.

The Stroop effect is a well-documented phenomenon, demonstrating both interference and facilitation effects. Many versions of the Stroop task were created, according to the purposes of its applications, varying in numerous aspects. While many versions are developed to investigate the mechanisms of the effect itself, the Stroop effect is also considered a general measure of attention, inhibitory control, and executive functions. In this paper, we implement “eStroop”: a new digital version based on verbal responses, measuring the main processes involved in (...) the traditional effect. eStroop features four categories of stimuli in four different colors: geometrical shapes, neutral words, congruent words, and incongruent words. The results of the administration to 307 University students confirm the Stroop effect and offer baseline data for future research and clinical testing. Direct comparisons with other recent versions of the task are discussed, offering insights into differences and similarities between different task variables. (shrink)

La epistemología de Kuhn ha inspirado investigaciones en el ámbito de la psicología del conocimiento. Del mismo modo los psicólogos investigadores de los procesos psico-cognitivos han tomado categorías kuhnianas para teorizar sus hallazgos. Finalmente, el mismo Kuhn se volvió hacia ellos para ilumin..

Dysfunctions of the neural circuits that implement social behavior are necessary but not a sufficient condition to develop schizophrenia. We propose that schizophrenia represents a disease of general connectivity that impairs not only the “social brain” networks, but also different neural circuits related with higher cognitive and perceptual functions. We discuss possible mechanisms and evolutionary considerations.

The possibility of obtaining stem cells from human embryos has given rise to an intensive legal and ethical debate. In this paper, attention is paid to the normative disparity and ambiguity in Europe. An argument for the need for a minimal legal harmonization is made; and a prudent and flexible way to reach this successfully is suggested. Establishing a common legal framework seems to be the only way to guarantee true competitiveness for the European scientific community.

Le nom de Brunschvicg est indissolublement lié à celui de Pascal. Sa grande entreprise éditoriale est restée inégalée, comme ses très nombreuses études dédiées directement ou non à l’auteur des Pensées. Pascal a été pour Brunschvicg l’interlocuteur d’une vie entière : cela s’entend du philosophe et du mathématicien qui affrontent l’infini, mais aussi du polémiste chrétien avec qui Brunschvicg a dit n’avoir « pas une idée en commun », mais dont il a saisi les secrets plus qu’aucun autre. Cet article (...) étudie la contribution de Brunschvicg comme éditeur, puis s’attache à cerner la figure brunschvicgienne d’un Pascal dont les Pensées, « nées du miracle » et « pleines de son âme », expriment, bien davantage que l’oeuvre de Descartes et plus directement que celle de Spinoza, les tensions constitutives de la conscience moderne.

Investigating school performance and competencies, especially on leadership, received a considerable attention in the past. In fact, there have been multitudes of evidence that leadership can impact school performance, student achievement, or outcome. Also, there was no single measurement of school performance. This study examined the influence of leadership and core behavioral competencies on the school performance of school heads. This was to build a new model of school performance. Using an explanatory research design, it administered a survey questionnaire to (...) 192 randomly chosen school heads from the 37 districts of Department of Education Division of Surigao del Sur. Also, it used data mining for the performance ratings of school heads from the division office. Regression analysis tested three hypothesized models of school performance where leadership and core behavior competencies serve as independent variables. Results showed that leading people was a significant predictor of school performance. Thus, leading people can best explain the school improvement as a proposed model. The results have implications for future research, leadership practice, and theoretical development of school performance model among school heads. (shrink)

A Bioética, que podemos qualificar, sem a menor dúvida, como uma ciência jovem - embora cheia de vigor, dinamismo e em plena expansão - se ocupa, desde as multifacetadas óticas das grandes perguntas que se formula a cada dia, o homem moderno, em torno da vida. Neste livro, os autores tratam de alguns aspectos conceituais que, às vezes, são obliterados no discurso bioético. Por exemplo, quais as relações que se interpõem entre Bioética e Direito, começando por delimitar cada uma destas (...) disciplinas. (shrink)

Visual feedback regulation during movement is not fully captured in Plamondon's kinematic theory. However, numerous studies indicate that visual response-produced feedback is a powerful determinant of performance and kinematic characteristics of target-directed movement.

Nous vivons dans une société mondialisée apparemment unie par une vision commune de l’humanité. Mais derrière l’illusion première d’un ‘’Nous’’ déjà là, se cache la réalité de l’hétérogénéité des croyances, des modes de vies et des cultures. Modèles différents entre pays et dans les pays eux-mêmes, sur le plan mondial comme ‘’national’’, nous cherchons encore ce qui constitue ce Nous tant rêvé. Quel est donc le fondement de notre vie commune? Qu’est-ce qui nous permet de dire que nous faison...

En 1997 se cumple el IV Centenario de la publicación de las Disputaciones Metafísicas de Suárez. Indudablemente no puede pasar inadvertida esa fecha si se tiene en cuenta que estamos ante el libro español de filosofía que ha influido más en el pensamiento europeo, muy concretamente durante el siglo XVII. Tanto la estructura del libro, alejada de los comentarios de Aristóteles, como el que se manifiesta tanto en el abultado número de reediciones, como en los temas que, desde las páginas (...) de Suárez, pasaron a las diversas corrientes del pensamiento moderno. Tanto los autores racionalistas encabezados por Descartes, como los pensadores alemanes —católicos o protestantes— se alimentaron generosamente del contenido de las Disputaciones Metafísicas de Suárez. Este artículo pretende sólo ser un recordatorio de tan señalada fecha. (shrink)

The essay explores the world of Jurisprudential Legal ethics, which ever closer claims the status of jurisprudential issue deeply woven into the contemporary debate about the concept and the nature of law. The paper briefly explores the leading jurisprudential theories about the lawyer’s role, in attempt to outline that the conceptualization of the lawyers’ role and the nature of their professional commitments are both a function of the concept of law we adopt, mainly focusing on the “positivist turn” in legal (...) ethics. In the conclusive section the paper I address the abuse-of-law filtes thesis of lawyering. Such reading moves from the idea that legal rules do not provide about their own application, thus there is room for a general practical discourse that regards the scope of advocacy and provides a proper role for legal ethics that would be independent from the bare respect of the settled law.
