We give a rough statement of the main result. Let D be a compact subset of ℝ3× ℝ. The propagation u of a wave can be noncomputable in any neighborhood of any point of D even though the initial conditions which determine the wave propagation uniquely are computable. A precise statement of the result appears below.

There are no moral cookbooks—no algorithms for whipping up moral confections to suit every occasion. But more modest and flexible tools might still be useful for practical ethics. One team describes how professionals can be taught to use a framework for understanding moral problems.

This paper offers a contribution to debates around integrative aspects of systems biology and engages with issues related to the circumstances under which physicists look at biological problems. We use oral history as one of the methodological tools to gather the empirical material, conducting interviews with physicists working in systems biology. The interviews were conducted at several institutions in Brazil, Germany, Israel and the U.S. Biological research has been increasingly dependent on computational methods, high-throughput technologies, and multidisciplinary skills. Quantitative scientists (...) are joining biological departments and collaborations between physicists and biologists are particularly vigorous. This state of affairs raises a number of questions, such as: What are the circumstances under which physicists approach biological problems in systems biology? What kind of interdisciplinary challenges must be tackled? The paper suggests that, concerning physicists’ move to work on biological systems, there are common reasons to move, the transition must be understood in terms of degrees, physicists have a rationale for simplifying systems, and distinct conceptions of model and modeling strategies are recurrent. We identified problems regarding linguistic clarity and integration of epistemological aims. We conclude that cultural unconformities within the systems biology community have important consequences to the flow of scientific knowledge. (shrink)

While there has always been discourse seeking to discredit feminism and its proposals using false arguments, as the movement has gained ground, the effort to discredit it has increased. Based on cases reported by the media websites Maldita.es, in its section Maldito Feminism, Newtral.es and Efe Verifica, we point out the important presence of anti-feminist content in the disinformation present in social media. We analyse the underlying ideology and the reasons why this discourse is particularly damaging to the feminist movement (...) today and to society in general, as new technologies make disinformation even more dangerous. We conclude our research by drawing a parallel between this phenomenon and Susan Faludi's analysis of the anti-feminist reaction in the 1980s, looking at the new challenges facing feminism in this fight against post-truth.

Reseña de la obra Carta de una mujer indignada desde el Magreb a Europa de Wassyla Tamzali (Cátedra 2011)).

La riche collection d'objets en faïence du musée gréco-romain d'Alexandrie, dont nous préparons la publication complète, comprend plus de mille trois cents pièces découvertes, pour la majeure partie d'entre elles, à Alexandrie ou dans sa région. Nous présentons ici un tableau de la vaisselle ptolémaïque et romaine en insistant plus particulièrement sur les procédés de fabrication et la typologie de ces objets et offrons un état de la question sur la localisation des ateliers et le commerce de cette vaisselle.

In the thirteenth century, the influential logician Afḍal al-Dīn al-Khūnajī departed from the Avicennan view that the subject matter of logic is “second intentions”. For al-Khūnajī, the subject matter of logic is “the objects of conception and assent”. His departure elicited intense and sometimes abstruse discussions in the course of subsequent centuries. Prominent supporters of Khūnajī's view on the subject matter of logic included Kātibī, Ibn Wāṣil and Taftāzānī. Defenders of Avicenna's view included Ṭūsī, Samarqandī and Quṭb al-Dīn al-Rāzī. This (...) article presents the outline of the development of this discussion down to the end of the fourteenth century and attempts to reconstruct the major arguments of both sides.Au xiiie siècle, l'influent logicien, Afḍal al-Dīn al-Khūnajī, se démarque du point de vue avicennien d'après lequel ce sont les “intentions secondes” qui forment le sujet de la logique. Pour al-Khūnajī, le sujet de la logique, ce sont “les objets des conceptions et des assentiments”. Cet écart par rapport à la formulation avicennienne va susciter, au cours des siècles suivants, d'intenses et parfois abstruses discussions. Dans le camp de ceux qui adhèrent au point de vue d'al-Khūnajī, on trouve des auteurs tels que Kātibī, Ibn Wāṣil et Taftāzānī. En revanche, Ṭūsī, Samarqandī et Quṭb al-Dīn al-Rāzī se rangent dans le camp des défenseurs du point de vue d'Avicenne. Cet article présente les grandes lignes qui marquent le développement de cette discussion jusqu'à la fin du xive siècle et tente de reconstruire les arguments des deux partis.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

Encadrant le Sophiste, le Théétète et le Politique, pris tous les deux ensemble, soulèvent des questions et suggèrent des réponses quant à la double relation entre le philosophe et le politique, d’une part, et entre Socrate et l’Étranger d’Élée, d’autre part. Je montre ici que certains aspects de la Digression du Théétète sur la nature des philosophes servent à critiquer les questions que pose LaRépublique ainsi que les réponses qu’elle donne sur la philosophie et la politique . Cette critique prépare (...) ainsi le terrain pour les différentes analyses qui sont données dans le Politique, dialogue qui sépare l’enquête sur la royauté ou la politique, des réflexions sur le bonheur, précisément de cette façon que réclame le philosophe dépeint par le Socrate de la Digression. J’avance que Socrate ne pouvait lui-même proposer l’idéal du vrai politique, bien que certains éléments du Théétète en signalent le besoin. Cet idéal peut bien être vécu par un philosophe ; toutefois devenir un politique transforme en profondeur le philosophe , au point que le Politique estime plus correct de le définir comme un politique plutôt que comme un philosophe. Je suggère finalement, en m’appuyant sur ce qui précède, que Socrate et l’Étranger d’Élée sont complémentaires, en ce que tous deux sont engagés dans la philosophie, sans qu’aucun des deux ne puisse la définir ou l’incarner complètement.Considering the Theaetetus and Statesman together – as the two dialogues explicitly said to flank the Sophist – both raises and suggests answers to questions about the relationship between philosopher and statesman, and the relationship between Socrates and the Eleatic Stranger. It is argued that aspects of the Theaetetus « Digression » on the nature of philosophers serve to criticise the questions raised and answers given about philosophy and statecraft in The Republic and so to introduce the different analysis of these matters which will be given in the Statesman, which separates its inquiry into kingship or statecraft from its reflections on happiness in just the way called for by Socrates’ philosopher in the « Digression ». It is then argued that the ideal of a true statesman is one which Socrates could not have advanced, although aspects of the Theaetetus signal the need for such an ideal. And that ideal is one which may be lived out by a philosopher, but in becoming a statesman, crucial aspects of that philosopher are redefined such that the Statesman suggests that it is more correct to define him as a statesman than as a philosopher. Finally, it is suggested drawing on aspects of the preceding that the relationship between Socrates and the Eleatic Stranger is complementary in that both are committed to philosophy, although neither can define or exhibit it fully.
