Orientation et réussite dans les filières scientifiques
1995
International audience; Cet article vise à sensibiliser les enseignants à l'analyse des situations concrètes de la classe à la lueur des apports de la recherche. On y trouve une présentation synthétique de leurs résultats ainsi que des encadrés, centrés sur l'action à mener sur ltrois points décisifs de la vie en classe : la mise en oeuvre du curriculum prescrit : - l'organisation du travail dans la classe, le contenu des programmes et des manuels - Les interactions maitres-élèves, les pratiques d'évaluation, les interactions entre élèves, - les phénomènes d'orientation
Dimensionality and factorial invariance of religiosity among Christians and the religiously unaffiliated: A cross-cultural analysis based on the Inte…
2019
We present a study of the dimensionality and factorial invariance of religiosity for 26 countries with a Christian heritage, based on the 1998 and 2008 rounds of the International Social Survey Programme (ISSP) Religion survey, using both exploratory and multi-group confirmatory factor analyses. The results of the exploratory factor analysis showed that three factors, common to Christian and religiously unaffiliated respondents, could be extracted from our initially selected items and suggested the testing of four different three-factor models using multi-group confirmatory factor analysis. For the model with the best fit and measurement invariance properties, we labeled the three resulting…
Sociologie de l'école (3ème édition)
2006
06002; Cette troisième édition, totalement refondue, d'un manuel devenu " la " référence sur le monde de l'école, des élèves et des enseignants, explore le domaine de manière systématique et objective, et sous des aspects divers : place de l'école dans la société (politiques scolaires, inégalités de carrière, enjeux de la réussite scolaire, évolution des analyses théoriques), mais aussi acteurs et pratiques (profession enseignante, programmes, pratiques éducatives des familles, métiers d'élève). Outre la mise à jour de toutes les données et une actualisation générale de son contenu, l'ouvrage propose de nombreux éléments inédits sur les effets des politiques éducatives, la construction et l…
A key role for cyclic nucleotide gated (CNG) channels in cGMP-related retinitis pigmentosa.
2011
The rd1 natural mutant is one of the first and probably the most commonly studied mouse model for retinitis pigmentosa (RP), a severe and frequently blinding human retinal degeneration. In several decades of research, the link between the increase in photoreceptor cGMP levels and the extremely rapid cell death gave rise to a number of hypotheses. Here, we provide clear evidence that the presence of cyclic nucleotide gated (CNG) channels in the outer segment membrane is the key to rod photoreceptor loss. In Cngb1(-/-) x rd1 double mutants devoid of regular CNG channels, cGMP levels are still pathologically high, but rod photoreceptor viability and outer segment morphology are greatly improve…
Cerium effect on the phase structure, phase stability and redox properties of Ce-doped strontium ferrates
2006
Nanostructured perovskite-type Sr1−aCeaFeO3−x, (0⩽a<0.15) powders have been prepared by citrate–nitrate smoldering auto-combustion. Their phase structure and stability, surface and morphological properties, reduction behavior and interaction with oxygen have been investigated by X-ray Powder Diffraction combined with Rietveld Analysis, 57Fe Mossbauer and X-ray Photoelectron Spectroscopies, N2-adsorption method, Temperature Programmed Reduction and Oxidation experiments. Our results reveal that citrate–nitrate auto-combustion method is effective in obtaining single phase Sr1−aCeaFeO3−x. The Sr1−aCeaFeO3−x structure is cubic only for a⩾0.06, while for a<0.06 remains tetragonal. Moreover, for …
Structural and morphological properties of Co-La catalysts supported on alumina/lanthana for hydrocarbons oxidation
2004
Abstract Two Al 2 O 3 (24 wt%)–La 2 O 3 (76 wt%) supported Co–La oxides with Co loading 4 wt% and different La content (1 and 9 wt%) were prepared by co-impregnation of the support, the aluminum–lanthanum oxide, with cobalt and lanthanum nitrates in aqueous solution and successive calcination at 800 °C for 4 h. The alumina–lanthana was synthesized by the sol–gel method. The samples were characterized by X-ray diffraction (XRD) and Rietveld refinement in order to identify the crystalline phases and their relative weight. H 2 -TPR (Temperature Programmed Reduction) experiments were recorded with the aim to identify the different Co phases present. Co 3 O 4 and LaCoO 3 were formed for La loadi…

Salivary apoptotic cells in oral (pre-) cancer as a potential diagnostic means
2015
Background: Apoptosis is a genetically programmed form of cell death which is indispensable for development and homeostasis of multi-cellular organism. Objectives: The aim of this study was to find out the salivary apoptotic cells in oral precancerous and cancerous patients and furthermore to observe the potential diagnostic value of salivary apoptotic cells in detection of oral pre-cancer and cancer. Materials and Methods: Unsimulated saliva was collected from a group of 103 subjects diagnosed with oral (pre-) cancer and a control group of 30 healthy age- and gender-matched individuals. The test group diagnosed with (pre-) cancer was further subdivided in 4 lesion groups oral squamous cell…
