In recent years, there has been a substantial amount of work in reverse mathematics concerning natural mathematical principles that are provable from RT, Ramsey's Theorem for Pairs. These principles tend to fall outside of the "big five" systems of reverse mathematics and a complicated picture of subsystems below RT has emerged. In this paper, we answer two open questions concerning these subsystems, specifically that ADS is not equivalent to CAC and that EM is not equivalent to RT.

We investigated the source of the visual search advantage of some emotional facial expressions. An emotional face target (happy, surprised, disgusted, fearful, angry, or sad) was presented in an array of neutral faces. A faster detection was found for happy targets, with angry and, especially, sad targets being detected more poorly. Physical image properties (e.g., luminance) were ruled out as a potential source of these differences in visual search. In contrast, the search advantage is partly due to the facilitated processing (...) of affective content, as shown by an emotion identification task. Happy expressions were identified faster than the other expressions and were less likely to be confounded with neutral faces, whereas misjudgements occurred more often for angry and sad expressions. Nevertheless, the distinctiveness of some local features (e.g., teeth) that are consistently associated with emotional expressions plays the strongest role in the search advantage pattern. When the contribution of these features to visual search was factored out statistically, the advantage disappeared. (shrink)

The paper deals with the question whether logical truth carry information. On the one hand it seems that we gain new information by drawing inferences or arriving at some theorems. On the other hand the formal accounts of information and information content which are most widely known today say that logical truth carry no information at all. The latter is shown by considering these accounts. Then several ways to deal with the dilemma are distinguished, especially syntactic and ontological solutions. A (...) version of a syntactical solution is favoured. (shrink)

In recent decades, Total Quality Management (TQM) has become an important phenomenon in the world of business, but the implications and scope of quality programs are quite different everywhere. Since different explanations have been given, most authors agree that management commitment and leadership are indispensable elements for a successful TQM implementation. Nevertheless, the study of the literature reflects a terminological confusion on this point. The authors of this paper argue that commitment and leadership are not synonymous terms.While committed managers may (...) lead the process of quality using exclusively their formal authority, those who are leaders generate a kind of influence that goes further than that. This paper suggests a multidimensional perception of leadership and upholds that only by considering the ethical dimension of leadership, together with technical and psycho-emotive ones, it is possible to explain more accurately interpersonal influences beyond the scope of power. As an illustrative example of the importance of considering each dimensions, the authors present two case studies of TQM implementation. (shrink)

Frente a las concepciones del Derecho como norma, como hecho o como valor (que caracterizan, respectivamente, al norrnativismo, al realismo jurídico y al iusnaturalismo), se propone aquí un cuarto enfoque que consiste en ver el Derecho como argumentación (y que cohra especial relevancia en las sociedades democráticas). Sin embargo, no hay una única forma de entender la argumentación jurídica. Aunque conectadas entre sí, en el trabajo se distinguen tres concepciones: la formal, la material y la pragmática o dialéctica; muchas cuestiones (...) que se plantean en el ámbito de la teoría de la argumentación jurídica pueden resolverse -o aclararse- teniendo en cuenta esa triple perspectiva.

When engaging in verbal communication, we do not simply use language to dispense information, but also to perform a plethora of actions, some of which depend on conventionalised, recurrent linguistic structures. Additionally, we must be skilled enough to arrive at the speaker’s intended meaning. However, speakers’ performance may deviate from certain habits and expectations concerning the way of speaking or accomplishing actions, while various factors may hinder comprehension, which may give rise to misappraisals of their respective abilities and capacities as (...) competent language users. This paper discusses whether such misappraisals may be subsumed by any of the already identified types of epistemic injustice and proposes a new label for them. It also describes the consequences of those misappraisals and approaches their origins from a cognitive perspective. (shrink)

This article shows how macro-historical processes of change can activate robust and enduring forms of citizenship practice, providing both survey-based evidence for this claim and a theorization of the causal mechanisms involved. Focusing on the case of Portugal, where democratization followed the historically unusual path of social revolution, we examine survey data on civic practice covering twenty countries and find Portugal to be a world leader in public participation in the electronic public sphere. When we examine the subsection of the (...) population socialized politically in the country’s post-revolutionary democracy, we find another important indicator of lively citizenship practice. The article takes the examination of this specific national case as the basis for developing an argument of broad theoretical relevance on the social underpinnings of lively and participatory citizenship practice. With an empirical foundation for our claims in survey data and other sources, our analysis of Portugal offers an interpretation of the case, leading to substantial revision of assumptions in the extant literature. More importantly, through our examination of this case, we show how large-scale macro-historical processes of change can encourage lively civic practice manifested at the individual level. Our argument highlights the importance of hierarchy-challenging collective experiences that reconfigure cultural frameworks and reorient the character of institutional practice. We take up the implications of this argument for cases lacking a history of revolution and find certain parallels with national cases shaped by movements of social reform as in the social democracies of Scandinavia.

Diez, M.A. Discurso ... -- Urdaneta, A. Contestación ...

El presente artículo recoge un texto inédito hasta la fecha del filósofo español Manuel Sacristán Sacristán (1925-1985) en torno al libro El futuro del Partido Comunista Francés, un ensayo de Waldeck Rochet (1969), entonces secretario general del PCF. En el mismo pueden observarse motivaciones políticas de Sacristán características de su tiempo que parecen prefigurar parte de la caracterización que más adelante realizará en torno al eurocomunismo, donde la firme defensa de los valores democráticos en el marxismo no es incompatible (...) con críticas a determinadas involuciones político-institucionales en el campo de los partidos comunistas europeos de la época.

Has philosophy paid sufficient attention to love? It is evident that the thinkers of the past expended a large part of their intellectual energies on talking about feelings, passions, emotions or affections, to mention just some of the terms under which, one way or another, love has tended to be subsumed. By doing so they undoubtedly granted it a philosophical importance, but not necessarily the kind that should be its due. Because love is much more than a philosophical subject with (...) the same rank as the most important ones: in the end it is, to put it rather abruptly, what makes philosophy itself possible. Why not consider love as we traditionally consider the experience of astonishment, that is, as foundational, as prephilosophical, in the same sense that we commonly talk of the prepolitical? To dispute just for a moment with the authority which has held the monopoly of the prephilosophical for so long: if we are astonished it is because we love to know. Only someone who already loves wisdom is in a position to be astonished. (shrink)

El autor trata de hacer balance, treinta años después, de lo que ha significado en el panorama del pensamiento jurídico la aparición de la Teoría del Derecho (Legal Theory, Rechtstheorie). El autor estudia los supuestos y razones del nacimiento de la Teoría del Derecho, como intento de superación de las limitaciones e insuficiencias del iusnaturalismo, del iuspositivismo y de su Teoría General del Derecho, así como de la Filosofía del Derecho postpositivista. Tras analizar el programa de la Teoría del Derecho (...) en sus direcciones anglosajona (Legal Theory) y alemana (Rechtstheorie), el autor hace un juicio de sus resultados (aportaciones e insuficiencias), postulando la posibilidad y necesidad de una Teoría Fundamental del Derecho que se configuraría como una ontología jurídica integral (material y formal al mismo tiempo).

El artículo revisa los límites teóricos que unen y separan la lógica de Aristóteles de la lógica aristotélica y la lógica de primer orden. Considera las razones para sostener la actualidad de la lógica de Aristóteles y se pregunta por la unidad de la disciplina, destacando la importancia de la noción de ciencia en la definición de lógica. The article deals with the theoretical limits which unify Aristotle's logic with Aristotelian logic and First Order Logic, and it realizes their differences (...) too. It examines the reasons to maintain the presence and actuality of Aristotle's logic and discovers the importance of the notion of science in defining the nature of logic. (shrink)

El propósito de este estudio es mostrar que la discusión sobre la autoría del Peri Hermeneias atribuido a Apuleyo, asunto bien difícil de determinar a ciencia cierta, puede recibir elementos de juicio interesantes desde la aclaración de que el De syllogismo categorico de Boecio y el PeriH de Apuleyo son similares entre. Así, este artículo pretende evidenciar que no sólo la exposición sobre lógica aristotélica que hizo el autor de PerH, sino también la de Mario victorino, que no nos ha (...) llegado, la de TuIIíus Marcellus Carthaginensis, que tampoco sobrevivió, y las posteriores de Boecio y Marciano Capella, son todas dependientes de la primera y original exposición de la lógica de aristotélica hecha por Teofrasto en sus analíticos Primeros, o por algún autor de su entorno.
