Multiple modalities in insect warning displays have additive effects against wild avian predators
2019
Allocation to different components of defence has been suggested as an explanation for the existence of multiple aposematic morphs in a single population. We tested whether there are trade-offs between warning colouration and chemical defence or whether these have an additive effect when combined, using blue tits (Cyanistes caeruleus) as predators and the polymorphic wood tiger moth (Arctia plantaginis) as prey. We used artificial edible models (with and without the moths’ defensive fluids) with paper wings whose colour and pattern properties matched those of real moths. When the models were presented sans defensive fluids or when the fluids were presented without colour cues, we detected n…

Trapped? Exploring the lives of young women in France and England who are labelled NEET and economically inactive
2021
International audience; Through a comparison of France and the UK, this paper analyses the position of young women who are defined as not in education, employment or training (NEET) and economically inactive (EI). Little is known about the NEET EI group and how this status shapes young people’s lives during school-to-work transition. Consequently, the NEET EI group remains a ‘hidden’ problem in many countries and impacts to a much greater extent on young women, due to their propensity to assume caring responsibilities. Despite France and the UK having very different types of policy intervention and welfare support, there are similarities between them in terms of NEET EI populations and the …
Los nuevos derechos sociales: El derecho al cuidado como fundamento del pacto constitucional
2016
ResumenNos encontramos ante un momento histórico y político que sugiere una revisión constitucional, con necesidades específicas y diferentes a las de 1978. Existen nuevas demandas que exigen que se revise el pacto constitucional. Algunas afectan directamente al catálogo de derechos, especialmente a los llamados derechos sociales, y se refieren por un lado, a la necesidad de otorgar a los derechos sociales ya reconocidos la consideración de fundamentales con todo lo que ello conlleva; y por otro, a la necesidad de crear nuevos derechos. El previsible aumento de personas necesitadas de cuidados, la escasez de servicios públicos para su asistencia, el tipo de cuidado informal prestado casi ex…

In the current context, which necessitates a reduction in inputs in crop systems and boosting of production of plant proteins to reduce France’s dependency on feed imports,, growing legumes represents an alternative. Grain legumes are major sources of proteins for animal and human nutrition. In the UMR1347 Agroécologie, the objectives of the study group "déterminismes Génétiques et Environnementaux de l’Adaptation des Plantes à des Systèmes de culture Innovants" (GEAPSI) are to promote legume cultivation and adaptation to environmental stresses, via multidisciplinary approaches (genetics, ecophysiology, molecular physiology). This thesis project was carried out in the "Étude des Mécanismes …
GOUVERNANCE D'ENTREPRISE ET POUVOIR INFORMATIONNEL DES BENEFICES COMPTABLES EN FRANCE ET AUX Etats-Unis
2007
International audience; La gouvernance d'entreprise a connu de très grandes évolutions en France et aux Etats-Unis depuis 2001. Ces évolutions n'ont pas conduit à une convergence linéaire entre les deux systèmes de gouvernance, mais à des emprunts réciproques en matière de réglementation et de mécanismes de contrôle implantés par les sociétés. Ces particularités en matière de gouvernance et de comportement des investisseurs financiers conduisent à un effet différent des mécanismes de contrôle sur le pouvoir informationnel des bénéfices comptables pour les investisseurs financiers. Les résultats indiquent que pour le contexte américain, la concentration de la propriété améliore le pouvoir in…
