Cet article développe l'idée selon laquelle la communication d'informations peut, en économie contribuer à modeler la «réalité» même sur laquelle ces dernières sont sensées porter. Il montre d'une part comment cette idée est apparue dans la discipline économique vers la fin des années 1970 et d'autre part qu'elle se traduit par des conséquences épistémologiques importantes.This article develops the idea that the communication of information can, economics help shape the "reality" even when they are supposed to wear. It shows both how (...) this idea emerged in the discipline of economics in the late 1970s and on the other hand it results in important epistemological consequences. (shrink)

Le projet d’une apologétique que Blondel concrétise en 1913 dans Comment réaliser l’apologétique intégrale ? s’inscrit dans un contexte culturel français particulièrement riche et, de ce fait, complexe. Il est aussi marqué par un événement particulièrement grave, le décret romain du 5 mai 1913 suspendant les Annales de philosophie chrétienne dirigées par le P. Laberthonnière avec la collaboration de Blondel. L’auteur explicite d’abord le contexte de l’intervention de Blondel en 1913, contexte où les événements littéraires ont une grande part, mais (...) où les incidences politiques marquées d’anticléricalisme, ne sont pas négligeables. C’est dans ce contexte que paraît l’ouvrage de Blondel qui veut montrer que le Catholicisme est un fait qui s’impose inévitablement, le point de vue de l’interlocuteur étant primordial dans ses exigences de raison et la variété de ses objections. Fondamentalement, la tâche de l’apologiste est de répondre aux questions difficiles que se pose l’homme qui pense. L’importance de l’ouvrage de Blondel, qui tient aux prolégomènes qu’il expose, provoquera paradoxalement de nombreux malentendus dont l’auteur expose les principaux, permettant de rétablir l’originalité et la force du projet blondélien.The project of an apologetics that Blondel put together in 1913 in How to realise the integral apologetics ? fits into a French cultural context especially rich and, for this reason, complex. It is also marked by a particularly serious event, the Roman decree of May 5, 1913, suspending the Annales de philosophie chrétienne directed by Father Laberthonnière with Blondel’s collaboration. The author first describes the context of Blondel’s intervention in 1913, a context where literary events play a big part, but where political incidents, marked by anticlericalism, are not negligible. It is in this context that the work of Blondel appears. He wants to show that Catholicism is a fact that imposes itself inevitably, the point of view of the interlocutor being primordial in his demands of reason and the variety of his objections. Fundamentally, the work of the apologist is to answer the difficult questions that arise to the person who reflects. The importance of Blondel’s work, which is based on the prolegomena that he expounds, will paradoxically provoke many misunderstandings, of which the author exposes the principle ones, but allows the originality and power of Blondel’s project to be restored.

The participation of patients in the training of health professionals constitutes a paradigmatic break, not only with regard to what is going on in this particular field but also with regard to what can be observed in all training courses for the helping professions. The purpose of this article is to consider this mobilization of patient trainers both as an actual change and as a potential operator of change. To do this, we will rely on an intervention research aimed at (...) promoting partnership in health and on the functioning and productions of one of the working groups dedicated to the training of health professionals.

Economics has developed into one of the most specialised social sciences. Yet at the same time, it shares its subject matter with other social sciences and humanities and its method of analysis has developed in close correspondence with the natural and life sciences. This book offers an up to date assessment of economics in relation to other disciplines. -/- This edited collection explores fields as diverse as mathematics, physics, biology, medicine, sociology, architecture, and literature, drawing from selected contributions to the (...) 2005 Annual Conference of the European Society for the History of Economic Thought (ESHET). There is currently much discussion at the leading edges of modern economics about openness to other disciplines, such as psychology and sociology. But what we see here is that economics has drawn on (as well as contributed to) other disciplines throughout its history. In this sense, in spite of the increasing specialisation within all disciplines, economics has always been an open discipline and the chapters in this volume provide a vivid illustration for this. -/- Open Economics is a testament to the intellectual vibrancy of historical research in economics. It presents the reader with a historical introduction to the disciplinary context of economics that is the first of its kind, and will appeal to practising economists and students of the discipline alike, as well as to anybody interested in economics and its position in the scientific and social scientific landscape. -/- Table of Contents -/- Introduction: Economics in relation to other disciplines Richard Arena, Sheila Dow and Matthias Klaes Part I.

As case management is under development in France for elderly people, this study sets out to identify and analyse key situations responsible for ethical dilemmas for French case managers. We based our study on the analyses of individual interviews made with case managers and focus-group discussions, bringing together all case managers working in local organisations running for at least a year. We identified three situations giving rise to ethical dilemmas: in the order of importance, the refusals of care, the practicalities (...) of collecting and sharing personal data and the allocation of resources. These three situations can lead to conflict between the principle of beneficence and those of respect for autonomy, non-maleficence and justice. We describe here how French case managers practically deal with these situations. (shrink)

Human interactions are often improvised rather than scripted, which suggests that efficient coordination can emerge even when collective plans are largely underspecified. One possibility is that such forms of coordination primarily rely on mutual influences between interactive partners, and on perception–action couplings such as entrainment or mimicry. Yet some forms of improvised joint actions appear difficult to explain solely by appealing to these emergent mechanisms. Here, we focus on collective free improvisation, a form of highly unplanned creative practice where both (...) agents' subjective reports and the complexity of their interactions suggest that shared intentions may sometimes emerge to support coordination during the course of the improvisation, even in the absence of verbal communication. In four experiments, we show that shared intentions spontaneously emerge during collective musical improvisations, and that they foster coordination on multiple levels, over and beyond the mere influence of shared information. We also show that musicians deploy communicative strategies to manifest and propagate their intentions within the group, and that this predicts better coordination. Overall, our results suggest that improvised and scripted joint actions are more continuous with one another than it first seems, and that they differ merely in the extent to which they rely on emergent or planned coordination mechanisms.

The neural crest is a transient population of multipotent progenitors arising at the lateral edge of the neural plate in vertebrate embryos. After delamination and migration from the neuroepithelium, these cells contribute to a diverse array of tissues including neurons, smooth muscle, craniofacial cartilage, bone cells, endocrine cells and pigment cells. Considerable progress in recent years has furthered our understanding at a molecular level of how this important group of cells is generated and how they are assigned to specific lineages. (...) Here we review a number of recent studies supporting a role for Wnt signaling in neural crest induction, differentiation, and apoptosis. We also summarize the timing of expression of a number of Wnt ligands and receptors with respect to neural crest induction. BioEssays 25:317–325, 2003. © 2003 Wiley Periodicals, Inc. (shrink)

We provide partial answers to the following problem: Is the class of Borel linear orders well-quasi-ordered under embeddability? We show that it is indeed the case for those Borel orders which are embeddable in R ω , with the lexicographic ordering. For Borel orders embeddable in R 2 , our proof works in ZFC, but it uses projective determinacy for Borel orders embeddable in some $\mathbf{R}^n, n , and hyperprojective determinacy for the general case.

We examined the course of caregiver motherese and the course of the infant’s response based on home movies from two single cases: a boy with typical development and a boy with autistic development. We first blindly assessed infant CG interaction using the Observer computer-based coding procedure, then analyzed speech CG production using a computerized algorithm. Finally we fused the two procedures and filtered for co-occurrence. In this exploratory study we found that the course of CG parentese differed based on gender (...) and child status. The course of an infant’s response to CG vocalization differed according to the type of speech and child status. Mothers spent more time interacting with infants, and fathers appeared to interact with their child preferentially between 12 and 18 months in the TD boy, but not in the AD boy. The TD boy responded equally well to motherese compared to other speech after 1 year of age. For the AD boy, the responses to both types of speech were lower than in the boy with TD and decreased from the second to the third semester. Keywords: Autism; motherese; early interaction; computational methods. (shrink)

We study the behavior of the game operator $$ on Wadge classes of Borel sets. In particular we prove that the classical Moschovakis results still hold in this setting. We also characterize Wadge classes ${\bf{\Gamma }}$ for which the class has the substitution property. An effective variation of these results shows that for all $1 \le \eta < \omega _1^{{\rm{CK}}}$ and $2 \le \xi < \omega _1^{{\rm{CK}}}$, is a Spector class while is not.

Dès les années 1960, la mixité s’instaure progressivement dans les établissements scolaires du secondaire sous l’effet de la réforme Berthoin. Pourtant l’Education Physique et Sportive échappe à l’impératif de cette mise en place. A partir d’une analyse de la revue Education Nationale de 1959 à 1975, cet article élucide les résistances de l’école à l’égard de la mixité et les représentations qu’elle véhicule sur l’éducation des filles et des garçons. Ainsi, le cas de l’EPS constitue un effet de loupe non (...) seulement des résistances de l’école à l’égard d’une rencontre physique des corps, mais aussi de la conviction, unanimement partagée par les acteurs du système éducatif, d’une différenciation affective, physique et sociale naturelle entre les sexes.

The Dominican theologian Durand of Saint-Pourçain (ca. 1275–1334), breaking from the wide consensus, made a two-pronged attack on concurrentism (i.e., the theory according to which God does more than conserving creatures in existence and co-causes all their actions). On the one hand, he shows that the concurrentist position leads to the unacceptable consequence that God is the direct cause of man’s evil actions. On the other hand, he attacks the metaphysical foundations of concurrentism, first in the version offered by (...) Thomas Aquinas and Giles of Rome, and then in a more general way. Against Thomas and Giles, he challenges Neoplatonic assumptions about causality and being. More generally, he establishes that God’s action and a creature’s action can be neither identical nor different, and thus cannot both be direct causes of the same effect. Without claiming that Durand’s series of objections are definitely unanswerable, we may at least observe that they have generally been underestimated (which earned him the lowly role of the mere foil of the concurrentist view in the history of philosophy) and are able to do considerable damage to concurrentism.

This book is a profound and eagerly anticipated investigation into what is left of a monotheistic religious spirit—notably, a minimalist faith that is neither confessional nor credulous. Articulating this faith as works and as an objectless hope, Nancy deconstructs Christianity in search of the historical and reflective conditions that provided its initial energy. Working through Blanchot and Nietzsche, re-reading Heidegger and Derrida, Nancy turns to the Epistle of Saint James rather than those of Saint Paul, discerning in it (...) the primitive essence of Christianity as hope. -/- The “religion that provided the exit from religion,” as he terms Christianity, consists in the announcement of an end. It is the announcement that counts, however, rather than any finality. In this announcement there is a proximity to others and to what was once called parousia. But parousia is no longer presence; it is no longer the return of the Messiah. Rather, it is what is near us and does not cease to open and to close, a presence deferred yet imminent. -/- In a demystified age where we are left with a vision of a self-enclosed world—in which humans are no longer mortals facing an immortal being, but entities whose lives are accompanied by the time of their own decline—parousia stands as a question. Can we venture the risk of a decentered perspective, such that the meaning of the world can be found both inside and outside, within and without our so-immanent world? -/- The deconstruction of Christianity that Nancy proposes is neither a game nor a strategy. It is an invitation to imagine a strange faith that enacts the inadequation of life to itself. Our lives overflow the self-contained boundaries of their biological and sociological interpretations. Out of this excess, wells up a fragile, overlooked meaning that is beyond both confessionalism and humanism. (shrink)
