Quelles approches didactiques pour le FLE en Australie occidentale ?
Cet article se base sur une recherche interprĂ©tative sâappuyant sur deux points de vue : celui la demande et celui de lâoffre en matiĂšre dâapprentissage/enseignement du FLE dans un micro-contexte. Par un jeu de regards croisĂ©s, nous mettrons en Ă©vidence un manque dâharmonisation entre le discours des apprenants et les approches didactiques mises en Ćuvre pour enseigner le français puis nous interrogerons quelques aspects de cet enseignement avant de proposer dâĂ©ventuelles formes de contextualisation.This article is based on interpretative research using two viewpoints: the supply and the demand of learning/teaching French as a Foreign Language in a micro-context. Using different perspectives, we will be able to highlight a lack of harmonization between the learnersâ discourse and the teaching approaches in French language classes. We will examine some of these aspects before proposing any form of contextualization
Subcortical volumes across the lifespan: Data from 18,605 healthy individuals aged 3â90 years
Age has a major effect on brain volume. However, the normative studies available are constrained by small sample sizes, restricted age coverage and significant methodological variability. These limitations introduce inconsistencies and may obscure or distort the lifespan trajectories of brain morphometry. In response, we capitalized on the resources of the Enhancing Neuroimaging Genetics through MetaâAnalysis (ENIGMA) Consortium to examine ageârelated trajectories inferred from crossâsectional measures of the ventricles, the basal ganglia (caudate, putamen, pallidum, and nucleus accumbens), the thalamus, hippocampus and amygdala using magnetic resonance imaging data obtained from 18,605 individuals aged 3â90âyears. All subcortical structure volumes were at their maximum value early in life. The volume of the basal ganglia showed a monotonic negative association with age thereafter; there was no significant association between age and the volumes of the thalamus, amygdala and the hippocampus (with some degree of decline in thalamus) until the sixth decade of life after which they also showed a steep negative association with age. The lateral ventricles showed continuous enlargement throughout the lifespan. Age was positively associated with interâindividual variability in the hippocampus and amygdala and the lateral ventricles. These results were robust to potential confounders and could be used to examine the functional significance of deviations from typical ageârelated morphometric patterns
Cortical thickness across the lifespan: Data from 17,075 healthy individuals aged 3-90 years
Delineating the association of age and cortical thickness in healthy individuals is critical given the association of cortical thickness with cognition and behavior. Previous research has shown that robust estimates of the association between age and brain morphometry require largeâscale studies. In response, we used crossâsectional data from 17,075 individuals aged 3â90âyears from the Enhancing Neuroimaging Genetics through MetaâAnalysis (ENIGMA) Consortium to infer ageârelated changes in cortical thickness. We used fractional polynomial (FP) regression to quantify the association between age and cortical thickness, and we computed normalized growth centiles using the parametric Lambda, Mu, and Sigma method. Interindividual variability was estimated using metaâanalysis and oneâway analysis of variance. For most regions, their highest cortical thickness value was observed in childhood. Age and cortical thickness showed a negative association; the slope was steeper up to the third decade of life and more gradual thereafter; notable exceptions to this general pattern were entorhinal, temporopolar, and anterior cingulate cortices. Interindividual variability was largest in temporal and frontal regions across the lifespan. Age and its FP combinations explained up to 59% variance in cortical thickness. These results may form the basis of further investigation on normative deviation in cortical thickness and its significance for behavioral and cognitive outcomes

Immunohistochemistry of CFTR in native tissues and primary epithelial cell cultures.
Studies on CFTR protein expression and localization in native tissues or in primary cultures of human epithelial cells are scarce due to the intrinsic instability of this protein, its low expression in most tissues and also to technical difficulties. However, such data are of the highest importance to understand the pathophysiology of CF. The purpose of this article is to outline several assays for the characterization of primary epithelial cultures and to review different CFTR immunostaining protocols
