Plusieurs grands thèmes sont abordés : le marché du travail en Europe, les femmes et les entreprises, les temps modernes de l'emploi féminin, l'insertion professionnelle, les politiques de formation-insertion, l'articulation entre travail, famille et carrière, les comportements individuels dans le système éducatif et les pratiques culturelles ou sportives.
Actions différentielles de xéno-hormones alimentaires sur les organes reproducteurs, le foie et le tissu adipeux chez le rat femelle : aspects endocr…
2007
Differential actions of dietary xenohormones on the reproductive organs, the liver and the adipose tissue in the female rat : endocrine, metabolic and morphogenetic aspects regarding the carcinogenic process. Over the past décades, the incidence of hormone-dependent cancers has dramatically increased in Western countries as compared to Asian countries. Environmental and dietary compounds able to mimic and interfère with endogenous hormones, especially reproductive ones, may be involved and among these xenohormones. xenoestrogens (XE) are particularly pointed at. The objective of this thesis was to détermine the conséquences of chronic dietary exposure to phytoestrogens and chemical xenoestr…
L'école des filles : Quelle formation pour quels rôles sociaux ? Nouvelle édition revue et actualisée
2004
04071; Si filles et garçons font des scolarités différentes, n'est-ce pas, in fine parce qu'ils sont différents ? Pourtant, les recherches accumulées sur ces questions depuis trente ans convainquent de ce qu'on fait face, non pas à de simples différences, mais bien à de véritables inégalités. Certes des évolutions prennent place, notamment dans la société, qui se répercutent dans l'école. Il fallait donc actualiser "L'école des filles" paru en 1990, et présenter à la fois un bilan actuel de ces inégalités indissociablement scolaires et sociales, et dessiner les tendances qui augurent des évolutions à venir.
Hybridization, developmental stability, and functionality of morphological traits in the ground beetle Carabus solieri (Coleoptera, Carabidae).
2006
Correspondance.: stephane.garnier@u-bourgogne.fr; International audience; The assessment of developmental stability in hybrids can provide valuable information in the study of species formation because it allows an evaluation of the degree of incompatibility of genetic systems that control developmental processes. The present study assessed the impact of two hybridization events, assumed to have occurred at different times, on developmental instability in the ground beetle Carabus solieri . Developmental instability was estimated in 678 individuals from 27 populations from the fluctuating asymmetry (FA) levels of four morphological traits: the tibia length of middle and hind legs, which are…
Propriétés spectrales des filtres usuels en économie : désaisonnalisation par CENSUS XII, et différences d'ordre d
1985
This study concerns the efficiency of usual statistical filters in economics to reduce the tendencial and seasonal components : the moving average processes of CENSUS Xll seasonal adjustment method and the difference sof d order early proposed by BOX-JENKINS. We are herein using the spectral and cospectral analyses to know whether the other components keep stable in the filtering process and whether the leads and lags found on the basis of the initial original data are kept after these filtering processes. One application illustrates the problems by means of monthly indicators that are highly representative of French economic evolution from 1963 up to 1982.This theoretical and empirical res…
Cell Differenciation markers in human umbilical cord; an immunohistochemical study
2011
The full-term human umbilical cord is made of three blood vessels ( two arteries and a vein) surrounded by the Wharthon's jelly, a soft cennective tissue made of new mesenchymal stromal cells and an abundant extracellular matrix. Both endothelial and Wharton's jelly are versdatile in their differenciation potential;tewhy have shown to be able to differentiate into sevaral cell lineages. Since the differentiation potential of these cells is very wide, we thought it could be interesting to investigate the expression of several cell differentiation markers in the different regions of human umbilical cord. Immunohistochemistry showed the expression of E- Cadherin and cytokeratyns in the amnioti…
