Compilation of the most important documents and speeches by Pierre de Coubertin on Olympism and the Olympic Games.

In the countries with a strong muslim immigration, the practice and the organization of Islam represent a national and international politica! stake. The Belgian state, which recognizes and supports the most important cults financially, recognized Islam in 1974. But this cult doesn't still obtain this state support and the questions concerning its organization are more complex than ever. Thelegislation is insufficient and its application almost non-existent. The debates on 'integrism' and hijab have confronted us with the problem of the integrating (...) role of Islam. The Belgian political world seems today to fear the influence of foreign countries on immigrants. All these factors throw light on the history and the present state of the Belgian legislation on the organization of the islamic cult, which this article analyses. (shrink)

The proposal of this article is to present and discuss the methodology applied in the frame of a socio-anthropological research held in Bolivia and Peru on child development and growth. The objectives of the investigation were to study the mother?s perceptions (and those of other related caretakers..

Two populations are subdivided into two categories of individuals (hawks and doves). Individuals fight to have access to a resource which is necessary for their survival. Conflicts occur between individuals belonging to the same population and to different populations. We investigate the long term effects of the conflicts on the stability of the community. The modelis a set of ODE's with four variables corresponding to hawk and dove individuals of the two populations. Two time scales are considered. A fast time (...) scale is used to describe frequent encounters and fightings between individuals trying to monopolize the resource. A slow time scale is used for the demography and the long term effects of encounters. We use aggregation methods in order to reduce this model into a system of two ODE's only for the total densities of the two populations which is found to be a classical Lotka-Volterra competition model. We study different cases of proportions of hawks and doves in both populations on the global coexistence and the mutal exclusion of the two populations. Pure dove tactics in both populations are unstable. In cases of mixed hawk and dove in both populations, there is coexistence. Pure dove or mixed hawk-dove tactics in one population can coexist with pure hawks in the other one when the costs of fightings between hawks are large enough. (shrink)

Pierre Soulages : régulièrement j’élimine des toiles, inabouties ou qui ont “tourné mal ”, banales, sans rien qui m’excite et qui sont d’ailleurs des sortes d’aventures avortées… Alors qu’à un moment, il y avait quelque chose qui était apparu, qui me paraissait intéressant à pousser, à intensifier, et puis ça s’est détourné, ça s’est terminé par quelque chose de morne, pas vraiment inachevé parce que l’inachevé c’est par rapport à un modèle parfait ou… qui n’est pas du tout ce (...) que je poursuiv...

An English translation of Pierre Bayle's posthumous last book, Entretiens de Maxime et de Themiste (1707), in which Bayle defends his skeptical position on the problem of the evil. This book is often cited and attacked by G.W. Leibniz in his Theodicy (1710). Over one hundred pages of original philosophical and historical material introduce the translation, providing it with context and establishing the work's importance.

Résumé Le présent article analyse d’un point de vue sémiotique les rapports entre la /lumière/ et l’/obscurité/ et les catégories discursives au sein d’un corpus de quatre textes de la littérature du dix-neuvième et vingtième siècle. Il s’agit de montrer que les propriétés physiques et sensibles fondent les structures sémio-narratives et orientent les catégories axiologiques, thymiques, spatiales et temporelles. Autrement dit, on observe une primauté de la lumière et de l’obscurité en tant que catégories organisées en structure élémentaire qui génère, (...) par un système de conversion, les unités abstraites et concrètes aux niveaux successifs du parcours génératif.

L'actualite du kantisme n'est plus a demontrer. Que l'on songe a l'ethique de la discussion, a la theorie de la justice, a la philosophie des relations internationales, au probleme des arguments dits transcendantaux ou encore a la theorie de l'experience esthetique, la pensee de Kant temoigne aujourd'hui d'une incontestable vigueur et d'une etonnante jeunesse. Cette contemporaneite de Kant se traduit par de multiples tentatives de dialogue avec cette oeuvre afin d'en degager la pertinence pour le debat actuel. L'oeuvre de (...) class='Hi'>Pierre Laberge a su repondre de maniere exemplaire a ses ordres de preoccupations dans l'etude de Kant. Les auteurs sollicites ont eu l'occasion de collaborer avec Pierre Laberge et lui rendent ici un hommage posthume. Ce recueil reflete ainsi cette double exigence d'actualiser le kantisme et d'en analyser les textes. (shrink)

As the result of the complexity inherent in nature, mathematical models employed in ecology are often governed by a large number of variables. For instance, in the study of population dynamics we often deal with models for structured populations in which individuals are classified regarding their age, size, activity or location, and this structuring of the population leads to high dimensional systems. In many instances, the dynamics of the system is controlled by processes whose time scales are very different from (...) each other. Aggregation techniques take advantage of this situation to build a low dimensional reduced system from which behavior we can approximate the dynamics of the complex original system.In this work we extend aggregation techniques to the case of time dependent discrete population models with two time scales where both the fast and the slow processes are allowed to change at their own characteristic time scale, generalizing the results of previous studies. We propose a non-autonomous model with two time scales, construct an aggregated model and give relationship between the variables governing the original and the reduced systems. We also explore how the properties of strong and weak ergodicity, regarding the capacity of the system to forget initial conditions, of the original system can be studied in terms of the reduced system.
