The study of political behaviors and attitudes among adults and young people has been approched by three ways : sociological approach, psychological approach and rational choice approach. After having explained the sociological one, we focused on the theory of political reasonning (developed by S.W. Rosenberg). We linked it with the development of political socialization. [less ▲]

Le présent article a pour objectif d’étudier l’effet de l’étendue de la divulgation d’informations sur l’asymétrie d’informations et la liquidité des titres des entreprises françaises. Notre échantillon regroupe 196 entreprises françaises cotées à l’indice SBF 250 sur une période s’étalant de 2004 à 2007. Les résultats montrent que l’étendue de la divulgation d’informations dans les rapports annuels influence positivement la liquidité du marché français. Ceci est expliqué par l’effet négatif des mécanismes d’informations sur la composante sélection adverse. Cet effet est d’autant plus confirmé par l’effet de l’application des normes IFRS rendues obligatoires pour les entreprises françaises à partir de 2005. Ce résultat devrait inciter les autorités françaises et les entreprises à améliorer davantage leur environnement informationnel comme moyen indispensable pour réduire les coûts de l’asymétrie d’informations et prévenir le risque d’illiquidité.

OBJECTIF. Etude évaluant la relation entre l¿administration d¿une chimiothérapie et les altérations cognitives chez les patientes âgées atteintes d¿un cancer du sein. METHODOLOGIE. 62565 patientes ont été incluses. Les critères d¿éligibilité sont: avoir une couverture complète assurance-maladie, être exemptes d¿altérations cognitives à la ligne de base, avoir reçu une chimiothérapie dans les 12 mois qui suivirent le diagnostic, être âgées de 65 à 89 ans. C'est une étude rétrospective sur une durée de 16 ans. RESULTATS. (voir article). DISCUSSION. Les résultats montrent que le groupe avec chimio et le groupe sans chimio sont équivalents quant aux démences induites par les médicaments une fois que les caractéristiques des patientes et de la tumeur sont prises en compte. Cette étude montre aussi que la maladie d'Alzheimer, les démences vasculaires et les autres types de démences sont plus présentes chez le groupe de patientes ayant reçu une chimiothérapie par rapport au groupe de patientes sans chimiothérapie. Enfin, les deux groupes de patients sont équivalents quant aux troubles cognitifs. Le traitement chimiothérapeutique n'aurait donc pas d'impact sur les troubles cognitifs non dégénératifs. CONCLUSION. Cette étude ne corrobore pas les études précédentes qui associaient la chimiothérapie à un risque accru d¿altérations cognitives à un stade sévère. [less ▲]

In the framework of the International Liquid Mirror Telescope (ILMT) project, a new method for testing the optical quality of liquid mirrors has been developed. The optical quality of liquid mirrors may be affected by the presence of wavelets in the liquid layer. This talk explains how it is possible to detect these defects by measuring the deflection they induce to a laser beam reflected on the liquid surface. Moreover, this method allows to characterize the different parameters of the wavelets, making possible to simulate their impact on the point spread function of the ILMT. Focus will be done on the experimental setup of the method. [less ▲]

A unique statistical data analysis method has been developed for reducing nulling interferometry data. The idea is to make use of the statistical distributions of the fluctuating null depths and beam intensities to retrieve the astrophysical null depth in the presence of fluctuations. The approach yields an accuracy much better than is possible with standard data reduction methods, because the accuracy of the null depth is not limited by the sizes of the phase and intensity errors but by the uncertainties on these errors. The result is an improvement in the instrumental null depth measurement limit of roughly an order of magnitude. We show in this paper that broadband null depths of 10-4 can be measured in the lab with our infrared Fiber Nuller without achromatic phase shifters. On sky results are also dramatically improved, with measured contrasts up to 5 x 10-4 with our instrument mounted on the Hale telescope at the Palomar Observatory. This statistical analysis is not specific to our instrument and may be applicable to other interferometers. [less ▲]

The small angular distance (<100 mas) and the huge flux ratio (10^7) between an Earth-like exoplanet in the so-called habitable zone and its host star makes it very difficult to direct image such systems. Nulling interferometry consists of a very powerful technique that combines destructively the light from two or more collectors to dim the starlight and to reveal faint companions in its vicinity. We have developed a new nulling experiment based on the fiber nuller principle (Serabyn et al. 2006 , Martin et al. 2008). This fully symmetric reflective nulling bench aims at testing broadband nulling in both H and K bands as well as characterizing photonic fibers for modal filtering. We present in this paper the design, the development as well as preliminary results of the experiment. [less ▲]

Performance comparison between JWST/MIRI and VLT/SPHERE for exoplanet detection Charles Hanot, Olivier Absil, Anthony Boccaletti, Céline Cavarroc, Jean Surdej In the context of exoplanet detection, a large majority of the 400 detected exoplanets have been found by indirect methods. Today, progress in the field of high contrast imaging has allowed direct images of several exoplanetary systems to be taken (cf. HR 8799, Fomalhaut). In the near future, several new instruments are going to dramatically improve our sensitivity to exoplanet detection. Among these, SPHERE ( Spectro Polarimetric High contrast Exoplanet REsearch ) at the VLT and MIRI ( Mid Infra-Red Instrument) onboard JWST will both be equipped with coronagraphs to reveal faint objects in the vicinity of nearby stars. In this paper, we make use of the most recent evolutionary models of young (sub-)stellar objects and exoplanets to derive their luminosities in order to compare the sensitivity of SPHERE to that of MIRI. From this comparison, we present a catalogue of targets which are particularly well suited for MIRI with possible detections of planets down to (sub-)Saturn masses. [less ▲]

In a Web 2.0 context, negative user-generated content (UGC) that damages the brand reputation can be easily produced and quickly spread. There is a lack of literature on how to measure the value destruction, known as doppelgänger brand image (DBI). The authors define DBI as the appearance, or reinforcement, of negative associations at the brand reputation level. Brand reputation is the collective brand image that is shared by multiple stakeholders. Using brand concept mapping (BCM) on two corporate brands, this study shows the effect of exposure to negative UGC on the brand image perception and measures the impact of this exposure on DBI. The authors use a two*two between-subjects design with 280 consumers in order to study the effects of the type of media and source credibility, brand experience and Internet experience on the DBI. The results suggest that, the negative UGC will cause an increase in the frequency of mentions of negative associations. At the reputation level, if the brand already has a DBI, an exposure to negative UGC will reinforce it. However, if the brand reputation is mostly positive, a single exposure to negative UGC will not create a DBI. The results also confirm the effect of source credibility and type of media on the likelihood of DBI. The experience with the brand and with Internet will reduce the risk of DBI. [less ▲]

The European transport policy has focused on sustainable transport solutions. One of its objectives for freight transport is to restore the balance between modes and to develop intermodality. Among the various types of intermodal transports, this research is concerned with rail-road container terminals embedded in a hub-and–spoke network. These terminals will further be referred to as hubs. Hub-and-spoke networks have been implemented in a number of transportation systems when it is favourable to consolidate and disseminate flows at certain locations called hubs. The efficiency of such a network depends on the location of the hubs. The problem is to find the optimal hub locations and to allocate the remaining nodes to these hubs. This problem is known as the p-hub median problem (p-HMP) where p is the number of hubs to locate. This location-allocation problem is proved to be NP-hard. The time needed to solve it increases as the number of nodes exponent three. Thus, in order to model rail-road transport on the trans-European networks, a subset of nodes that can be considered as good potential locations is needed. We applied the p-HMP to a set of potential locations obtained by both spatial aggregation of demand nodes using hierarchical clustering methods and by a flow-based approach which takes the flows of commodities and their geographic spread into account. They showed that the latest method gives better results and that is why it is retained to determine a set of potential locations. The set of potential locations is used as input for an iterative procedure. One of the main contributions of this research is to propose this iterative procedure based on both the p-HMP and the multi-modal assignment problem. Moreover, the objective function of our p-hub median formulation includes the costs for pre- and post-haulages by road, trans-shipment (according to the number of handled containers into account) and rail haulage. Furthermore, in the p-hub median problem, the total demand is assigned to the hubs. In this research however, the demand can be assigned over all the transportation modes, with the possibility (but not the obligation) of using the trans-shipment facilities. Finally, we presents a methodology able to compare road and rail-road intermodal market areas that takes the network structures, the operation costs and the location of the rail-road terminals into account. This methodology is applied to the optimal configurations obtained by the resolution of the p-HMP and the p-hub centre problem (p-HCP) for the whole trans-European network. Indeed, p-HMP has an efficiency goal by minimizing the total transportation cost. The hub network design obtained by this method can sometimes lead to unsatisfactory results when worst-case origin-destination pairs are separated by a very large distance. Therefore, the p-HCM meets the equity objective by minimizing the maximum cost of a combined transport. [less ▲]

La bande dessinée est-elle un médium moderne ou postmoderne ? Les dessinateurs les plus créatifs, chevilles ouvrières des maisons d’édition indépendantes, défendent la modernité du médium. On pense notamment à la position de Jean-Christophe Menu sur le sujet. Dans le « manifeste » de l’Association (les 3 numéros de la revue « théorique » L’éprouvette), plusieurs auteurs défendent l’actualité de la notion d’Avant-Garde. Leur thèse se résume comme suit : si la peinture ou la littérature ont vu l’époque des Avant-Guardes laisser place à la postmodernité, la bande dessinée, au moins, n’a pas encore été touchée par la désillusion qui lui est propre. Immaturité revendiquée des dessinateurs qui croient encore pouvoir révolutionner totalement les codes de leur médium et proposer une version neuve de la bande dessinée, en rupture avec ses origines. Cette notion de « rupture » (ou de « crise » d’ailleurs) est tout-à-fait centrale et caractéristique de la modernité – la postmodernité, de par son système de citations (même impertinentes et détournées), ne fait que renouer avec un passé stérile qu’elle recycle infiniment (parce qu’elle est dénuée de tout enjeu révolutionnaire, de toute lutte interne). Mais par ailleurs, la bande dessinée est traversée par des éléments de la postmodernité. Du point de vue de son contenu, elle marque de plus en plus un désaccord radical avec la modernité consumériste, le culte de la marchandise et des effets de « mode », la vie citadine et l’homogénéisation des masses. Elle est l'un des lieux d’expression privilégiés de la désillusion du peuple relativement aux grandes utopies de transformation rationnelle du monde et d’émancipation de l’homme (expression privilégiée des minorités de genre ou de race – ce qui est souvent mis en exergue dans les cultural studies). Par ailleurs, à suivre Jean-François Lyotard, la postmodernité ne se caractérise pas uniquement par sa violente performativité (le culte de l’Utilité remplaçant dans les savoirs scientifiques celui de la Vérité), mais elle montre aussi une prise en compte croissante des instabilités et développe une « paralogie » que nourrirait probablement une certaine bande dessinée (et plus généralement une certaine para-littérature).
