L'arrêt de la vaccination anti-aphteuse obligatoire priva le réseau d'épi- démiosurveillance d'une source de financement majeure et de contacts entre ses divers acteurs. Afin de poursuivre l'animation de ce réseau, une politique évolutive en faveur des contrôles sur les animaux introduits dans les cheptels suscita l'in térêt, à divers titres, des membres du réseau. Aidé par des subventions du Conseil Général de Charente-Maritime, il fut possible d'élargir progressive ment les dépistages tandis que les contreparties des éleveurs, financières ou techniques, s'étoffaient. L'accueil de cette action varie selon l'espèce et le risque sanitaire res senti. Les résultats essentiels furent une modification de l'offre des commer çants de bétail privilégiant des animaux sains, la mise en œuvre par les éle veurs de dispositions réglementaires essentielles à la protection sanitaire de leur cheptel, et la confirmation du rôle d'interlocuteur et d'interface essentiel des vétérinaires sanitaires entre les pouvoirs et les éleveurs. ; Tentatives for enforcing an epidemological network : INTRODUCTION CONTROLS IN CHARENTE MARITIME The stop of the compulsory vaccination against footh and mouth disea se deprived the epidemiological network of a major source of funding and of contacts amongstakehoders.

Essential results were a modification of the offer cattle providers privileging healty animals, the implementden by the breeders of rules essen tial to the sanitary protection of their livestock, and the confirmation of the essential role of the sanitary veterinarians as interlocutor and interface bet ween authorities and breeders.

We describe and test two process models of candidate evaluation. The memory-based model holds that evaluations are dependent on the mix of pro and con information retrieved from memory. The impression-driven model holds that evaluations are formed and updated "on-line" as information is encountered. The results provide evidence for the existence of stereotyping and projection biases that render the mix of evidence available in memory a nonveridical representation of the information to which subjects were exposed. People do not rely on the specific candidate information available in memory. Rather, consistent with the logic of the impression-driven processing model, an "on-line" judgment formed when the information was encountered best predicts candidate evaluation. The results raise both methodological and substantive challenges to how political scientists measure and model the candidate evaluation process.
