We investigate the regional disparities in high-skilled foreign employment in Germany. The importance of different factors that influence highly qualified migrants’ decision to migrate to specific regions and especially the role of labour migration policy is analysed. Our results show that labour market variables and the supply of tertiary education are important for the location choice. Based on these empirical results, we discuss options of decentralised labour migration policy in Germany.  相似文献

Rats responded in a two-segment (variable-interval variable-interval) chain schedule. In one experiment, three subjects had either clicker, light, or clicker plus light as terminal-segment stimuli. All three responded at the highest rate when clicker plus light were present, thus showing additive summation. For three other subjects, initial-segment stimuli were either clicker, light, or clicker plus light. Two subjects responded at the lowest rate when clicker plus light were present, thus showing suppressive summation. In a second experiment, three subjects had either clicker, light, or neither clicker nor light as terminal-segment stimuli. None of these subjects showed reliable additive summation. Three other subjects had clicker, light, or neither as the initial-segment stimulus, and all three showed suppressive summation. Additive and suppressive summation both can be demonstrated with chain schedules, but stimulus parameters may be major variables in producing the effect.  相似文献

To evaluate the mediating effect of utilization propensity (UP) on gender differences in healthcare utilization (HCU), a representative sample of the German general population (N = 2,510) was assessed with questionnaires. Gender differences in HCU, UP, and the mediating effect of UP were investigated using regression analyses. UP was significantly associated with HCU. The explanatory power of gender for UP, and of UP for HCU was prevailingly weak. UP had a mediating effect on gender differences in HCU, but the effect was very small. This is partly attributable to common problems in the prediction of behavior by attitudes and the operationalization of UP.  相似文献
