Bessines – Le Grand Champ Est
Identifiant de l'opération archéologique : 204625 Date de l'opération : 2008 (SP) Plusieurs opérations de diagnostics et de fouilles ont été entreprises depuis 2003 au sud-est de la Communauté d’Agglomérations de Niort. Elles montrent une occupation protohistorique particulièrement dense de l’âge du Bronze à l’âge du Fer, au sud-est de l’ancien golfe des Pictons, notamment sur les communes adjacentes de Niort, à Aiffres et à Bessines. Suite au dépôt d’un projet de ZAC, une opération de diagno..
Stability in Cosmology, from Einstein to Inflation
I investigate the role of stability in cosmology through two episodes from the recent history of cosmology: (1) Einstein’s static universe and Eddington’s demonstration of its instability, and (2) the flatness problem of the hot big bang model and its claimed solution by inflationary theory. These episodes illustrate differing reactions to instability in cosmological models, both positive ones and negative ones. To provide some context to these reactions, I also situate them in relation to perspectives on stability from dynamical systems theory and its epistemology. This reveals, for example, an insistence on stability as an extreme position in relation to the spectrum of physical systems which exhibit degrees of stability and fragility, one which has a pragmatic rationale, but not any deeper one

The Integration of Immigrants into the Labour Market: The Case of Sweden
The current situation regarding the integration of immigrants in the labour market in Sweden is the consequence of a number of factors and developments. The past fifteen years have seen a higher share of humanitarian migration in Sweden than in the past. This is a form of migration for which labour market integration appears to be slower than for other forms of migration in all countries. At the same time there has been a growing diversification of migration away from “Western” countries to those with a greater cultural distance... S’agissant de l’insertion des immigrés sur le marché du travail suédois, il semblerait que la situation actuelle résulte d’un ensemble de facteurs et de développements. Les quinze dernières années ont vu une part plus importante de l’immigration humanitaire que par le passé. C’est une forme de migration pour laquelle l’intégration sur le marché du travail des personnes concernées est plus lente que pour les autres formes de migration. En même temps, il y a eu une augmentation de l’immigration en provenance de pays non « occidentaux » et partageant des cultures plus éloignées...
