Bio-ecological approach applied to adolescents’ health: Girls and boys in situations of contextual disconnection
2011
International audience; In this study, we base on Bronfenbrenner’s bioecological model and propose to examine health behaviours of adolescents – girls and boys – in light of the Person-Context transactions. More precisely, we consider as a special issue the relations between health and degraded contextual Person-Family and/or Person-School transactions. One thousand and six French middle-school (8th grade) adolescents, 479 boys and 527 girls, took part in this study. They were categorized into four groups: Family disconnected adolescents, School disconnected adolescents, Double disconnected adolescents (that is, adolescents who are disconnected to both contexts), and Not disconnected adoles…
Variabilité intra-saisonnière et multi-décennale de la téléconnexion entre les pressions de surface (100°W–50°E ; 30°–70°N) et les ENSO/LNSO (1873–19…

Abstract The relationships between an index of the NINO3.4 region and the wintertime sea level pressure (hereafter SLP) anomalies on the extratropical North Atlantic and the bordering areas (100°W–50°E; 30°–70°N) are studied for 1873–1996. This study emphasizes the need of a careful pooling of months and the multi-decadal variability of the ENSO/LNSO influence on the extratropical North Atlantic. We calculate the mean monthly climate anomalies for the 20 warmest and the 20 coldest NINO3.4 (170°–120°W; 5°N–5°S) years from October to March. The composite of SLP anomalies for the 20 warmest NINO3.4 years shows an anomalous trough centered near 30°W in November–December, and positive (respectiv…
Evénements de vie chez les adolescents en désaffiliation contextuelle
2006
International audience; Dans le cadre théorique du modèle bioécologique de Bronfenbrenner, nous avons élaboré deux échelles évaluant la qualité de transaction des adolescents vis-à-vis de deux contextes de vie significatifs : la famille et l’école. Ces échelles permettent d’identifier les adolescents en situation de désaffiliation familiale et/ou scolaire (perception négative, voire rejet de la famille, de l'école). Nous avons déjà montré que la désaffiliation simple (familiale ou scolaire) avait un effet délétère sur la santé des adolescents et que la désaffiliation double (familiale et scolaire) amplifiait les risques de troubles de santé. La présente recherche porte sur les liens entre l…
Development and preliminary validation of the contextual connection scale for adolescents (CCSA)
2009
This paper presents the development and validation of the Échelle d'affiliation contextuelle pour adolescents (EACA; Contextual Connection Scale for Adolescents, CCSA) within the framework of Bronfenbrenner's bioecological model (1995). This instrument comprises three subscales measuring connections in three different contexts: family, school, and peers. Two studies have been conducted with 1959 French adolescents to (1) test and confirm a three factor structure one factor per context and (2) evaluate criterion validity. The results show that this scale has good psychometric qualities and provides original and relevant materials for research and application.
Taxonomy and palaeobiogeography of the Cenozoic Euro-Mediterranean rissoid gastropod Galeodinopsis and its relationship with close genera
2014
The investigation of the Late Paleogene to Late Neogene species of rissoid gastropod Galeodinopsis in the Euro-Mediterranean area has supported the hypothesis that this genus is an intermediate form between two well-known rissoids, Alvinia and Manzonia. We recognized four species of Galeodinopsis: G. biangulata, G. germanica sp. nov., G. semperi (new name for Rissoa duboisii), and G. tiberiana. The oldest (very Late Eocene/Oligocene) representatives of Galeodinopsis, G. biangulata, and G. semperi, share similar shell shape and microsculpture with Alvinia. This suggests that Galeodinopsis originated from some Eocene species related to Alvinia. The new species represents the first occurrence …
Geometry control of the junction between two fractal curves
2012
International audience; The general objective of our work is to create a geometric modeller based on iterative processes. With this objective in mind, we have to provide tools that work with fractal objects in the same manner as with objects of classical topology. In this article we focus on the constructing of an intermediate curve between two other curves defined by different iterative construction processes. A similar problem often arises with subdivision surfaces, when the goal is to connect two surfaces with different subdivision masks. We start by dealing with curves, willing to later generalise our approach to surfaces. We formalise the problem with the Boundary Controlled Iterated F…

Polymeric scaffolds prepared via Thermally Induced Phase Separation (TIPS): Tuning of structure and morphology
2007
Scaffolds suitable for tissue engineering applications were prepared by Thermally Induced Phase Separation (TIPS) starting from a ternary solution PLLA/dioxane/water. The experimental protocol consisted of three consecutive steps, a first quench from the homogeneous solution to an appropriate demixing temperature (within the metastable region), a holding stage for a given residence time and a final quench from the demixing temperature to a low temperature (within the unstable region). A large variety of morphologies, in terms of average pore size and interconnection, were obtained upon modifying the demixing time and temperature, owing to the interplay of nucleation and growth processes dur…
The Impact of Age on the Association Between Physical Activity and White Matter Integrity in Cognitively Healthy Older Adults
2020
Cognition emerges from coordinated processing among distributed cortical brain regions, enabled through interconnected white matter networks. Cortical disconnection caused by age-related decline in white matter integrity (WMI) is likely to contribute to age-related cognitive decline. Physical activity (PA) has been suggested to have beneficial effects on white matter structure. However, its potential to counteract age-related decline in WMI is not yet well established. The present explorative study analyzed if PA was associated with WMI in cognitively healthy older adults and if this association was modulated by age. Forty-four cognitively healthy older individuals (aged 60–88 years) with d…
