The food sector and health sector become more and more intertwined. This raises many possibilities, but also questions. One
of them is the question of what the implication is for public trust in food and health issues. In this article, I argue that
the products on the interface between food and health entails some serious questions of trust. Trust in food products and
medical products is often based upon a long history of rather clear patterns of mutual expectations, yet these expectations
are not similar in both sectors. As long as the food sector and health sector remain distinct, these differences will not
lead to problems of trust, yet when new products are introduced, like functional foods or personalized dietary advices, trust
can be threatened. To prevent this, we need clarity with regard to what we can expect of these new products and of whom to expect what in this situation. This requires not␣only adequate information on operating procedures, but also a profound
debate␣on responsibilities and the explication and interpretation of moral values and norms. 相似文献

In an attempt to better understand the mechanism underlying lateral collision avoidance in flying insects, we trained honeybees
(Apis mellifera) to fly through a large (95-cm wide) flight tunnel. We found that, depending on the entrance and feeder positions, honeybees
would either center along the corridor midline or fly along one wall. Bees kept following one wall even when a major (150-cm
long) part of the opposite wall was removed. These findings cannot be accounted for by the “optic flow balance” hypothesis
that has been put forward to explain the typical bees’ “centering response” observed in narrower corridors. Both centering
and wall-following behaviors are well accounted for, however, by a control scheme called the lateral optic flow regulator, i.e., a feedback system that strives to maintain the unilateral optic flow constant. The power of this control scheme is
that it would allow the bee to guide itself visually in a corridor without having to measure its speed or distance from the
walls. 相似文献

This paper examines the consequences of various attitudes towards climate damages through a family of stochastic optimal control models (RESPONSE): cost-efficiency for a given temperature ceiling; cost-benefit analysis with a pure preference for current climate regime and full cost-benefit analysis. The choice of a given proxy of climate change risks is actually more than a technical option. It is essentially motivated by the degree of distrust regarding the legitimacy of an assessment of climate damages and the possibility of providing in due time reliable and non controversial estimates. Our results demonstrate that (a) for early decades abatement, the difference between various decision-making frameworks appears to matter less than the difference between stochastic and non stochastic approach given the cascade of uncertainty from emissions to damages; (b) in a stochastic approach, the possibility of non-catastrophic singularities in the damage function is sufficient to significantly increase earlier optimal abatements; (c) a window of opportunity for action exists up to 2040: abatements further delayed may induce significant regret in case of bad news about climate response or singularities in damages. 相似文献
