Modeling of 137Cs migration in soils using an 80-year soil archive: role of fertilizers and agricultural amendments
2008
An 80-year soil archive, the 42-plot experimental design at the INRA in Versailles (France), is used here to study long-term contamination by 137Cs atmospheric deposition and the fate of this radioisotope when associated with various agricultural practices: fallow land, KCl, NH4(NO3), superphosphate fertilizers, horse manure and lime amendments. The pertinence of a simple box model, where radiocaesium is supposed to move downward by convectional mechanisms, is checked using samples from control plots which had been neither amended, nor cultivated since 1928. This simple model presents the advantage of depending on only two parameters: α, a proportional factor allowing the historical atmosph…
Comprendre les courses ordinaires : Enjeux et implications pour les grandes surfaces alimentaires
2010
This article aims at registering the common shopping within the framework of the domestic life, like housework. This different perspective allows a better understanding of this behaviour of purchase. Retailers will find in this paper some ideas to improve the customers' satisfaction during the ordinary and regular shopping they do.
Le sens du regard Contribution sémiotique à la technique de l'eye-tracking face aux packagings produits
2009
International audience; This work is presenting a semiotic point of view of a promising but problematic tool of the communication field -eye-tracking- which is used in various fields to track and exploit the eye-path on an object. Drawing form a list of eye-paths on various packagings, the first step of the analysis was the identification without theoretical a priori- of fixed patterns in these paths. Several models can then be inferred on how the order of acquisition of the elements of an image or a pack might have an influence on the construction of their overall meaning.; Ce travail propose un point de vue sémiotique sur un outil du champ de la communication prometteur mais problématique…

Révolutionnaires et réformistes face au marxisme
2019
La critique du marxisme qu’entreprend Castoriadis à la fin des années 1950 dans Socialisme ou Barbarie est traditionnellement présentée comme un moment pivot dans sa carrière, qui lui fait abandonner la posture du penseur révolutionnaire « à l’ancienne » et donne à son œuvre une dimension nouvelle, philosophiquement et politiquement. Ce tournant, on le sait, n’est pas une rupture : plutôt une évolution, voire une libération – libération à l’égard de cadres intellectuels dépassés, d’un système...
The need for information in purchase situation and the information behavior in front of the shelf : use and effects of electronic interactive communi…
1999
The classic approach of buying behavior supposes that the consumption value derives from the evaluation of the technical, functionnal and symbolic features of the product. But, most of recents works use an experiential approach, for which the anticiped situation of consumption or use and the self concept are the essential elements of the consumption value. This thesis, devoted to information behavior in buying situation, attemps to conciliate these two paradigms until here opposite. The first part of this search investigates the concept of need for information. Its results, according to us, the activation ot two schemes, the first concerning the product acquisition, the second relative to t…

Couches minces d'oxynitrure de titane : la réactivité comme moyen original de caractérisation physico - chimique
2002
Titanium oxinitride thin films, TiNxOy, were elaborated on Si(100) by the MOCVD (Metal Organic Chemical Vapor Deposition) method, using titanium isopropoxide Ti(OCH(CH3)2)4 and ammonia NH3 as precursors. By varying the growth temperature, it is possible to modify the N/O ratio and change the conductivity of the films.The target of this work was to determine the composition and the structure of these TiNxOy thin films in order to understand the electrical properties. However, this study was difficult because classical characterization techniques (SEM, XRD, Raman, XPS...) were unable to describe the whole TiNxOy system. Indeed, only a structure which is isomorphic to TiN (NaCl structure) was …

Le management des activités culturelles et de loisirs : questions stratégiques et état des recherches académiques.
2005
National audience; La recherche académique en management des activités culturelles et de loisirs est un courant récent, apparu au début des années 90, mais dont la production est importante et éclectique. Trois axes peuvent être identifiés pour structurer ces recherches:l'analyse du comportement du public, la stratégie des institutions et la gestion de leurs décisions opérationnelles dans lesdomaines de la tarification, de la communication et de la distribution. Cet article analyse la convergence de ces recherches vers les interrogations opérationnelles des institutions du secteur.
