Influence de différentes pratiques agricoles sur la qualité et la santé des sols : étude de cas sur des vergers slovènes irrigués ou en agriculture b…
2011
Underestimation of soil properties and poor understanding of soil conditions can have many negative consequences, which results in quality or quantity of yield, soil degradation or even environmental pollution. According to importance of agricultural practices, our study focused on their impact on soil quality and health. The research took place from November 2003 to October 2007 in apple orchards in north-eastern Slovenia where two frequent agricultural practices were investigated: (i) drip irrigation on Calcaric Cambisol and its effects on structural stability and microbial biomass at Gačnik experimental station and (ii) combination of organic fertiliser (Campo guano) and liming in organi…
New molecular aspects of regulation of mitochondrial activity by fenofibrate and fasting
2000
Abstract Fenofibrate and fasting are known to regulate several genes involved in lipid metabolism in a similar way. In this study measuring several mitochondrial enzyme activities, we demonstrate that, in contrast to citrate synthase and complex II, cytochrome c oxidase (COX) is a specific target of these two treatments. In mouse liver organelles, Western blot experiments indicated that mitochondrial levels of p43, a mitochondrial T3 receptor, and mitochondrial peroxisome proliferator activated receptor (mt-PPAR), previously described as a dimeric partner of p43 in the organelle, are increased by both fenofibrate and fasting. In addition, in PPARα-deficient mice, this influence was abolishe…
A Brief Comparison of the Unconscious as Seen by Jung and Lévi-Strauss
2015
Retracing the primary common aspects between anthropological and psychoanalytic thought, in this article, we will further discuss the main common points between the notions of the unconscious according to Carl Gustav Jung and Claude Levi-Strauss, taking into account the thought of Erich Neumann. On the basis of very simple elementary logic considerations centered around the basic notion of the separation of opposites, our observations might be useful for speculations on the possible origins of rational thought and hence on the origins of consciousness.
La sémiotique russe à la recherche de son histoire : éléments pour l’Ecole sémiotique de Moscou et de Tartu
2013
International audience; On peut situer en 1989 l’origine de la réflexion russe « interne » sur l’histoire du structuralisme russe. Cetteannée-là parut en effet l’article de B. Gasparov « Tartusskaja škola 1960-h godov kak semiotičeskij fenomen »[« L’école de Tartu des années 1960 comme phénomène sémiotique »]2. Ce texte fut à l’origine d’une polémiquesur la place du mouvement sémiotique dans l’Union soviétique des années 1960-1980, dans l’histoireintellectuelle nationale mais aussi sur l’interprétation à donner de ce courant d’idées. Ce débat a étéprincipalement animé par d’anciens membres de ce groupe, que l’on a appelé « École sémiotique de Moscou et de Tartu ».
Le premier manifeste du structuralisme linguistique : le chapitre 20 de la Poétique d’Aristote
2013
International audience; 'Structuralisme' est un terme qui a beaucoup de significations. Ici, je vais employer le terme ‘structure’ dans la signification générale, rappelée par Christian Puech dans son Introduction, de “système de systèmes de valeurs”. L’idée que les langues sont des systèmes de systèmes de valeurs ne nait ni avec Saussure ni avec Troubetskoy ou Jakobson. Il s’agit d’un point de vue qui est apparu plusieurs fois dans l’histoire de la pensée et qui, pourtant, autant de fois a été oublié. Je vais donner quelques-unes des preuves qui montrent qu’Aristote a été parmi les premiers à penser que la langue verbale est justement un système de systèmes de valeurs.
On Jung and Lévi-Strauss unconscious: A brief comparison
2013
Retracing the main common aspects between the anthropological thought and the psychoanalytic one, in this paper we will further discuss about the main common points between the notions of unconscious according to Carl Gustav Jung and Claude Lévi-Strauss, taking into account the Erich Neumann thought. On the basis of very simple elementary logic considerations centered around the basic notion of separation of opposites, what will be said might turn out to be useful for some speculations upon possible origins of the rational thought, hence for the origins of consciousness.
Intérêts et apports de l'analyse des variables latentes pour le chercheur en sciences sociales : exemple d'application à l'économie de l'éducation
2002
The ambition of this article is modest. Initially, it aims at presenting in a sample manner the concepts that underpin the standard use of LISREL models and showing their usefulness in social science research. It then proposes, as an illustration of the theoretical presentation, an example of application relating to the use of school time in the education system.
Qu'est-ce que le structuralisme génétique ?

International audience
A. Bavelas, 1950, Communication Patterns in Task-Oriented Groups. Version bilingue et commentée
2021
Ce document du groupe fmr présente une version bilingue et commentée de l'article d'Alex Bavelas, Communication Patterns in Task-Oriented Groups, paru en 1950 dans la revue Journal of the Acoustical Society of America. S'appuyant sur les seuls travaux de Kurt Lewin et de ses élèves, et donc ne mobilisant ni la sociométrie ni la théorie des graphes au sens strict, l'auteur propose un ensemble de mesures permettant de mesurer l'efficacité de la communication au sein d'une structure donnée. Cet article a eu une influence importante dans différents champs de recherche (analyse de réseaux sociaux, management, psychologie, etc.).
Numerical vibroacoustic analysis of plates with constrained-layer damping patches
2011
International audience; A numerical vibroacoustic model that can manage multilayered plates locally covered with damping patches is presented. All the layers can have an on-axis orthotropic viscoelastic behavior. Continuity of displacements and transverse shear stresses at each interface is enforced, which permits to write the entire displacement field in function of the displacements of the-common-first layer, leading to a two-dimensional plate model. The problem is then discretized by Rayleigh-Ritz's method using a trigonometric basis that includes both sine and cosine functions in order to treat various boundary conditions. The excitation can be of mechanical kind (concentrated or distri…
