Une base de données sur les études de faunes des établissements ruraux en Gaule
2007
International audience; Une base de données nationale des études de faune, issues des établissements ruraux gaulois, esquisse, à partir de 272 fiches portant sur 200 sites, une première série de synthèses sur l'élevage en Gaule. Les conditions de mise en place de la base ainsi que la description de ses différents champs sont détaillées avec une première application sur la chasse. Des présentations sur les distributions chronologiques, régionales et hiérarchiques de l'élevage permettent de distinguer des ensembles. D'autres approches, enfin, combinant types de structure, entités géographiques, chronologie ou encore âge d'abattage des espèces, synthétisent les modalités de gestion des mammifè…
Analyse spectrale et texturale de données à haute résolution pour la détection automatique des maladies de la vigne
2019
‘Flavescence dorée’ is a contagious and incurable disease present on the vine leaves. In order to contain the infection, the regulations require growers to control each of the vine rows and to remove the suspect vine plants. This monitoring is done on foot during the harvest and mobilizes many people during a strategic period for viticulture. In order to solve this problem, the DAMAV project (Automatic detection of Vine Diseases) aims to develop a solution for automated detection of vine diseases using a micro-drone. The goal is to offer a turnkey solution for wine growers. This tool will allow the search for potential foci, and then more generally any type of vine diseases detectable on th…
Where do food likes and dislikes come from?
2020
Where do food likes and dislikes come from ? In other words, what are the factors that could explain why someone likes or dislikes a given food ? Most of the hedonic reactions to sensory stimulations brought by foods and, as a result reactions to foods carrying these sensory properties are learned through different learning mechanisms. The efficiency of these learning mechanisms mat depend on individual characteristics, in particular on the sensitivity to different sensory properties. Not all learnings are related to experiments with the food itself; many leamings depend on interactions within the family or social environment. Finally, cognitive determinants play also a role and, in particu…
Les stéréotypes nominaux et la combinatoire lexicale
2011
In this article, we are interested in the stereotypes associated with the names of substances and natural phenomena. We try to demonstrate, through their lexical combinatory, that the semantic representation of these names is constituted of the denotative meaning, built on the basis of a knowledge, and the stereotype, i.e. the conventional ideas on the appearance and the nature of the denoted objects.
Les déterminants personnels du bien-être de l’écolier, de ses satisfactions en classe et de sa performance scolaire
2017
This work focuses on the study of personal determinants of pupils' achievement and reactions toward class (well-being; satisfaction with teacher, learning and class). A theoretical model is tested by commonality analysis and refined by causal paths analysis. The results show that external and cognitive prior characteristics (age, gender, socio-occupational background, academic record) have direct effects on criteria variables, and indirectly via the attitudes toward school (negative feelings; scholastic interest; aspirations for future studies; "scholastic anxiety, worry and stress"; fun school). Using two structural models, we explained 39 % of the variance in academic achievement, and fro…
Le processus de choix alimentaire et ses déterminants : vers une prise en compte des caractéristiques psychologiques du consommateur
2006
This thesis aims to explore new research opportunities in the food field, proposing to explicitly include psychological factors as potential determinants of food choice process. It notes the consequences of the central role of pleasure in the mechanisms of ingestion, and the specific role of taste: the highly emotional nature of food consumption leads then to retain experiential approach and more specifically sensory marketing as a framework. The issue of research aims to investigate how sensory stimuli and the information associated with the product combine to influence, in a differentiated manner depending on the individual, consumption behavior.Methodologically, the research combines con…
