Maladies professionnelles et prévention : enquête sur la situation prévalant en Allemagne, Finlande, France, Italie et au Canada (Québec)

Le présent rapport se propose d'identifier la manière dont la prévention des pathologies professionnelles retenues dans le cadre de l'étude (pathologies dues à des substances chimiques ou facteurs physiques: amiante, bruit, ciment, huiles de coupe, isocyanates, poussières de bois, résines époxy) ainsi que des cancers professionnels est abordée dans les pays sélectionnés et de décrire des campagnes ayant fait la preuve de leur efficacité et perçues comme susceptibles d'être reprises en Suisse.

Italie 1915-1918 : communion nationale ou guerre de classes ?

À l'heure où la fascination esthétisante pour « l'horreur » semble gagner des adeptes en nombre toujours croissant, tant d'un point de vue historiographique que des différents usages publics et politiques qui en sont faits, cette contribution vise à repenser la guerre en tant qu'espace social signifiant. Elle s'inscrit en effet dans des dynamiques sociales et politiques « ordinaires ». Elle ne peut, dans cette optique, faire abstraction de la compréhension de l'ordre social existant avec son lot d'oppression, mais aussi de refus et de révolte. Cette contribution se propose d'envisager, à partir du cas italien, un cas limite trop souvent oublié dans l'historiographie européenne du premier conflit mondial, les pratiques mais aussi les représentations sociales du conflit, afin de saisir ce que la guerre peut apporter à la compréhension de la conflictualité sociale au début du XXe siècle. Mais aussi de chercher à savoir comment les « résistances » ouvertes ou celées qui s'expriment au cours de la guerre faite et vécue transforment le rapport des soldats à leur groupe social.

Massive nest-box supplementation boosts fecundity, survival and even immigration without altering mating and reproductive behaviour in a rapidly recovered bird population.

Habitat restoration measures may result in artificially high breeding density, for instance when nest-boxes saturate the environment, which can negatively impact species' demography. Potential risks include changes in mating and reproductive behaviour such as increased extra-pair paternity, conspecific brood parasitism, and polygyny. Under particular cicumstances, these mechanisms may disrupt reproduction, with populations dragged into an extinction vortex. With the use of nuclear microsatellite markers, we investigated the occurrence of these potentially negative effects in a recovered population of a rare secondary cavity-nesting farmland bird of Central Europe, the hoopoe (Upupa epops). High intensity farming in the study area has resulted in a total eradication of cavity trees, depriving hoopoes from breeding sites. An intensive nest-box campaign rectified this problem, resulting in a spectacular population recovery within a few years only. There was some concern, however, that the new, high artificially-induced breeding density might alter hoopoe mating and reproductive behaviour. As the species underwent a serious demographic bottleneck in the 1970-1990s, we also used the microsatellite markers to reconstitute the demo-genetic history of the population, looking in particular for signs of genetic erosion. We found i) a low occurrence of extra-pair paternity, polygyny and conspecific brood parasitism, ii) a high level of neutral genetic diversity (mean number of alleles and expected heterozygosity per locus: 13.8 and 83%, respectively) and, iii) evidence for genetic connectivity through recent immigration of individuals from well differentiated populations. The recent increase in breeding density did thus not induce so far any noticeable detrimental changes in mating and reproductive behaviour. The demographic bottleneck undergone by the population in the 1970s-1990s was furthermore not accompanied by any significant drop in neutral genetic diversity. Finally, genetic data converged with a concomitant demographic study to evidence that immigration strongly contributed to local population recovery.

Identity, immigration, and prejudice in Europe: a recognition approach

Social identity is a double-edged sword. On the one hand, identifying with a social group is a prerequisite for the sharing of common norms and values, solidarity, and collective action. On the other hand, in-group identification often goes together with prejudice and discrimination. Today, these two sides of social identification underlie contradictory trends in the way European nations and European nationals relate to immigrants and immigration. Most European countries are becoming increasingly multicultural, and anti-discrimination laws have been adopted throughout the European Union, demonstrating a normative shift towards more social inclusion and tolerance. At the same time, racist and xenophobic attitudes still shape social relations, individual as well as collective behaviour (both informal and institutional), and political positions throughout Europe. The starting point for this chapter is Sanchez-Mazas' (2004) interactionist approach to the study of racism and xenophobia, which in turn builds on Axel Honneth's (1996) philosophical theory of recognition. In this view, the origin of attitudes towards immigrants cannot be located in one or the other group, but in a dynamic of mutual influence. Sanchez-Mazas' approach is used as a general framework into which we integrate social psychological approaches of prejudice and recent empirical findings examining minority-majority relations. We particularly focus on the role of national and European identities as antecedents of anti-immigrant attitudes held by national majorities. Minorities' reactions to denials of recognition are also examined. We conclude by delineating possible social and political responses to prejudice towards immigrants.
