Markov decision processes (MDP) with finite state and action space have often been used to model sequential decision making over time in dairy herds. However, the length of each stage has been at least 1 mo, resulting in models that do not support decisions on a daily basis. The present paper describes the first step of developing an MDP model that can be integrated into a modern herd managemen...

The production of health policy-relevant research is necessary, but not sufficient, to promote its utilization in policy.

This article is a reflection on the social uncertainty caused by Influenza A and on the consequences that it can have on decision making in health promotion policies. We use concepts and metaphors of the Rational Choice Theory, among them, the "in gratitude effect" or the "distrust effect", as we analyse how these can become obstacles for the efficiency of prevention policies. Then, we focus on...
