RÉSUMÉ. Cet article aborde le problème de l’évaluation, par l’agent, de ses actions et interactions. Nous proposons un modèle des satisfactions différenciant actions individuelles et interactions avec les agents voisins. La satisfaction personnelle est calculée incrémentalement dans le temps suivant la perception de la progression de la tâche en cours. La satisfaction interactive est une évalua...

We review recent experimental results on time-dependent CP asymmetries in the B system from the BABAR and Belle experiments. Measurements of the α and β angles of the Unitarity Triangle of the CKM matrix are discussed. These measurements constitute stringent tests of the Standard Model, and are also used to search for new physics. SLAC-PUB-12886 03/05/2006--3/12/2006, La Thuile, Aosta Valley, I...

The conventional view would appear to define hysterical symptoms (whether so-called conversion symptoms or hysterical dissociation) in terms of a number of features.
