Many criticisms have been made of optimization theory (Laville, 1999a). These objections may be explained by the fact that human rationality is bounded – that decisions are constrained by cognitive limitations (Simon, 1982). In the present paper, I will show that if rationality is bounded, then we must study the processes of decision. My thesis is that cognitive limitations lead to procedural rationality. Although this assertion has already been sustained implicitly by Simon (1959) and explicitly by Mongin (1986), it (...) has not been argued in sufficient depth. (shrink)

Cluster randomized controlled trials (cluster RCTs) randomize whole clusters of individuals in testing two or more competing interventions. Here we will present the ethical problems raised by cluster RCTs concerning their effect on inequality. We argue that some inequalities generated by cluster RCTs are larger in scope than those generated from individual RCTs. We also argue that any cluster RCT-generated inequalities, which divide groups rather than individuals, are more problematic in type than the inequalities created in individual RCTs. These concerns (...) should be taken into consideration when designing research at the cluster level, and those conducting the research should consider modified research design strategies in cases where they believe the risk of generating inequalities is large.

L’auteure retrace les controverses qui ont émaillé l’histoire du principe de précaution en France dans les trente dernières années après son adoption au niveau international et européen. Elle montre que le principe de précaution constitue une dimension nouvelle de la rationalité adaptée aux défis de la société contemporaine.

L’auteur retrace l’histoire du droit de l’environnement dans l’entrelacement des droits privés, administratif, constitutionnel et international public. Elle montre que les notions de préjudice écologique, de sécurité humaine et de Droits de l’Humanité permettent, par-delà une simple responsabilité éthique, d’incarner juridiquement un véritable ordre public écologique.
