Using data of Swiss referenda from 1981 to 1999, this paper presents new empirical results which allow us to discriminate better between the decision and mobilisation hypotheses of electoral participation. First, the theoretical considerations are presented which lead to these hypotheses are presented as well as the theory of expressive voting, and a survey(More)
Hyaluronan is synthesized within the cytoplasm and exported into the extracellular matrix through the cell membrane of fibroblasts by the MRP5 transporter. In order to meet the law of electroneutrality, a cation is required to neutralize the emerging negative hyaluronan charges. As we previously observed an inhibiting of hyaluronan export by inhibitors of(More)
In this pilot study, we examine the relationship between the organisation of property rights and the economic importance of forestry on the one hand and the degree to which integrative nature conservation is formally implemented in forest policy on the other hand. Further, we are interested in whether political institutions moderate this relationship. We(More)
An effective planning of lot sizes is a key strategy to efficiently manage a combined manufacturing/ remanufacturing system in the presence of substantial setup costs. Due to its complex interdependen-cies, optimal policies and solutions have not been identified so far, but several heuristic approaches have been analyzed in recent contributions. The main(More)
In the area of reverse logistics, remanufacturing has been proven to be a valuable option for product recovery. In many industries, each step of the products' recovery is carried out in lot sizes which leads to the assumption that for each of the different recovery steps some kind of fixed costs prevail. Furthermore, holding costs can be observed for all(More)
