Towards a global view of dynamical systems, for the C1-topology.
2010
This paper suggests a program for getting a global view of the dynamics of diffeomorphisms, from the point of view of the C1-topology. More precisely, given any compact manifold M, one splits Diff1(M) in disjoint C1-open regions whose union is C1-dense, and conjectures state that these open set, and their complement, are characterized by the presence of • either a robust local phenomenon • or a global structure forbiding this local phenomenon. Other conjectures states that some of these regions are empty. This set of conjectures draws a global view of the dynamics, putting in evidence the coherence of the numerous recent results on C1-generic dynamics.
The Influence of Nanoparticle Shape on Protein Corona Formation
2020
Nanoparticles have become an important utility in many areas of medical treatment such as targeted drug and treatment delivery as well as imaging and diagnostics. These advances require a complete understanding of nanoparticles' fate once placed in the body. Upon exposure to blood, proteins adsorb onto the nanoparticles surface and form a protein corona, which determines the particles' biological fate. This study reports on the protein corona formation from blood serum and plasma on spherical and rod‐shaped nanoparticles. These two types of mesoporous silica nanoparticles have identical chemistry, porosity, surface potential, and size in the y ‐dimension, one being a sphere and the other a …
Un 'sujet qui fâche' : l'évaluation des enseignants en France, entre défense statutaire, injonction au professionnalisme et autonomie professionnelle
2017
International audience; Cet article analyse les projets de réforme de l’évaluation des enseignants en France depuis la fin des années 1990 ainsi que les réactions, notamment syndicales, qu’ils ont suscitées. Cette évaluation est considérée comme un analyseur privilégié pour étudier les réactions des enseignants au développement de nouvelles politiques de reddition de comptes. A partir de méthodes qualitatives (entretiens, analyse de dépêches de presse et de corpus de documents), il étudie plus spécifiquement les systèmes de négociation des différents projets de réforme d’une évaluation régulièrement contestée mais jamais réformée au moment où nous terminons cet article. Adoptant une perspec…
La spécialisation des productions et les spécialistes: Une introduction
2018
With the emergence of manufacturing based economies, specialised productions take on new dimensions during the Neolithic. Production networks progressively develop during the Neolithic and the Metal Ages and can be characterised according to their scale, how they are organised, the status of producers and the intensification of the trade of manufactured goods. This results on the one hand in mass production and on the other in the creation of highly technical objects on demand within a complex economic system of consumption and exchange. This is not seen as a linear progression but as a diversification of productions, products and know-how, the chronological and social contextualisation of …

Combined hexavalent diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliovirus-Hemophilus influenzae type b vaccine; Infanrix™ hexa: T…
2014
Infant vaccination using 2-dose priming at 3 and 5 mo of age with a booster at 11–12 mo of age was pioneered in Italy. The 3-5-11 schedule is now used in a growing number of European countries. Infanrix™ hexa (DTPa-HBV-IPV/Hib, GlaxoSmithKline Vaccines) was first licensed for use in 2000 and has been the only pediatric hexavalent vaccine available since 2005. We reviewed available clinical trial data describing the immunogenicity of DTPa-HBV-IPV/Hib when administered at 3, 5, and 11 mo of age, and conducted an analysis of safety using global and Italian post-marketing surveillance data. In Italy, DTPa-HBV-IPV/Hib has a demonstrated safety record extending over a decade of use, it has been a…

Stress au travail et santé : situation chez les indépendants
2011
Dans de nombreux secteurs d’activité, le stress au travail est considéré comme faisant partie des risques pour la santé auxquels peuvent être confrontés les travailleurs salariés et non-salariés ou indépendants. [br/] Le terme de "stress" peut avoir plusieurs définitions en fonction des disciplines médicales, biologiques, médico-sociales, des sciences humaines et sociales qui y font référence. Quelle que soit l’approche disciplinaire, le stress peut être considéré comme un élément d’un processus complexe, à la fois biologique, psychologique et social en réponse à une situation aversive.[br/] Le régime social des indépendants (RSI), qui assure la couverture maladie et de retraite des artisan…
