La connaissance du système éducatif contribue t'elle à rendre l'enseignant compétent ?
2012
L'objet de ce chapitre est d'identifier les instruments de pilotage de la formation des enseignants ainsi que ceux qui sont mobilisés lors des procédures de recrutement de ces enseignants. Il s'agira de tenter d'apprécier la cohérence ou la logique dans laquelle ces instruments s'inscrivent, de voir si les exigences qu'ils impliquent quant aux caractéristiques ou qualités que doivent manifester les enseignants sont similaires ou complémentaires ou encore si elles s'opposent. Nous observerons alors que les compétences que doivent maîtriser les enseignants sont différentes quand elles sont impliquées par les instruments de pilotage de la formation et quand elles sont impliquées par ceux qui p…

Estimation de la relation de salaires de Mincer : choix de specification et enjeux économétriques
2012
In the present doctoral thesis, we estimated Mincer’s (1974) semi logarithmic wage function for the French and Pakistani labour force data. This model is considered as a standard tool in order to estimate the relationship between earnings/wages and different contributory factors. Despite of its vide and extensive use, simple estimation of the Mincerian model is biased because of different econometric problems. The main sources of bias noted in the literature are endogeneity of schooling, measurement error, and sample selectivity. We have tackled the endogeneity and measurement error biases via instrumental variables two stage least squares approach for which we have proposed two new instrum…
A categorization and executive functions approach of food rejection in young children
2021
Food neophobia and pickiness are two strong psychological obstacles to young children’s consumption of fruits and vegetables, which are necessary components of a diet that facilitates normal and healthy development. It is therefore of critical importance to investigate the cognitive underpinnings of these two kinds of food rejection to promote the adoption of healthy eating behaviors. Food acceptance and rejection appear to be partly conditioned by children’s knowledge of the food domain. Knowledge allows children to recognize a given food, categorize it, and make inference-based decisions on its properties and possible consequences of consumption. Underdeveloped knowledge may cause food st…

Flore adventice du tournesol. Quelle évolution en trente ans ? Quelles caractéristiques favorisent la capacité d'infestation des cultures ?
2006
WEED FLORA EVOLUTION SINCE 1973: WHICH TRAITS SEEM TO HAVE FAVOURED THE CAPACITY OF INFESTING SUNFLOWER? We developed an analysis to pinpoint what biological, ecological or agronomical rules could underline the evolution of sunflower Helianthus annuus L.) weed flora over the past thirty years in France. By separately conducting a clustering of weed species according to their biological similarity and analysing the changes observed in the weed flora at the cluster group level, our approach could highlight beyond the list of species, what set of characteristics seemed to be determinant. The biological milarity between species then allows us to highlight which species could be of major concern…
Functionnalized magnetite nanoparticles for bimodal imaging MRI/PET
2015
Functionalized magnetite nanoparticles for bimodal MRI/PET imagingSuperParamagnetic Iron Oxide Nanoparticles (SPIONs) have been widely studied in the biomedical field due to their promising application as nanodrugs and MRI (Magnetic Resonance Imaging) contrast agents (T2). In this study, magnetite (Fe3O4) nanoparticles have been developed for use as contrast agents for MRI/PET (Positron emission tomography) double imaging. First, functionalized stable superparamagnetic SPIONs have been synthesized in a continuous hydrothermal reactor. During the synthesis, hydrophilic agents (citric acid, LDOPA, DHCA and PHA) have been grafted on the surface of the nanoparticles. The functionalization of th…
Modélisation des objets urbains pour l'étude des dynamiques urbaines dans la longue durée
2007
The use of GIS to study the spatial evolution of pre-industrial cities over the "longue durée" requires rigorously formalising heterogeneous data from different sources into robust entities. An initial model using the HBDS (Hypergraph Based Data Structure) method enabled us to distinguish social and spatial features. In this paper we develop a specific model for the temporal dimension. The definition of urban objects using social, spatial and temporal features enhances the study of urban dynamics of change over the "longue durée".
