European monetary policy and the ECB rotation model

This paper analyses the voting power of individual members of the ECB Governing Council and, in particular, that of the Executive Board in the light of recent information published by the ECB. Using the randomization scheme based on the multilinear extension of games, we modify the standard analysis in three ways. First, we include heterogeneous preferences of the Governing Council members. Second, we address the agenda-setting power of the ECB president. Third, we take into account the dynamic decision setting. We show that the rotation model is able to stabilize the position of the core countries of the euro area.     

INTERNATIONAL HEALTH CARE REFORM: THE NEED FOR COMPREHENSIVE MICRO-COMPARATIVE ANALYSIS

Microcomparison, or single‐component analysis, of health care systems offers a potentially better basis for reform than traditional macrocomparison analysis of aggregate elements. Using macroanalysis, available evidence shows that Germany provides cheaper but more effective hospital care than the United States. To find the causes for this outcome, we developed a microanalytic model of hospital administrators’ perceptions, financial ratios, medical outcomes, and pharmaceutical costs. However, only data on pharmaceutical costs were available and similar in both countries. Our significant outcome was development of a microcomparative model that gives world medical care providers new criteria for analyzing and improving cost to care rafios.     

Political regime change, economic liberalization and?growth accelerations

We examine whether the type of political regime, regime changes, and economic liberalization are related to economic growth accelerations. Our results show that growth accelerations are preceded by economic liberalizations. We also find that growth accelerations are less likely to happen the longer a political regime??be it a democracy or an autocracy??has been in place, while (a move toward) more democracy according to the Polity IV dataset reduces the likelihood of growth accelerations.     

The rise and fall of decentralization: A comparative analysis of arguments and practices in European countries

Abstract This paper addresses the arguments in favour of both the decentralization and centralization of public policy making. It points out that the same arguments are sometimes used to advance either claim and that in different countries opposite arguments are used to support the same claim. Clearly, the inherent features of centralization and decentralization are far from obvious. A closer look at the attention given to the issue by political parties at the national level in four European countries reveals that decentralization becomes an issue in these countries at different periods and as a cause of different arguments, which rather reflect the dominant values in the political culture than refer to inherent properties of decentralization itself. An analysis of opinions of local elites points at the relation between their opinion on decentralizing responsibilities in a specific field and the support for existing institutional arrangements, their own influence in the policy field and the predisposition towards decentralization tendencies. This results in the conclusion that the support for decentralization tendencies is more closely related to existing specific institutional arrangements, and to the degree to which it is expected to influence one's own position, than to its inherent merits.     

Segmental analysis for cocaine and metabolites by HPLC in hair of suspected drug overdose cases

Hair samples of eight postmortem cases were analyzed in segments of 1 to 3 cm for cocaine, benzoylecgonine and cocaethylene. Samples were prepared for analysis by digestion in 0.1 M HCl and subsequent extraction with mixed-mode solid-phase extraction columns. Measurement was made by reversed-phase, narrow-bore HPLC and fluorescence detection using two laboratory-made internal standards. The concentrations were in the region of 0.29–316 ng/mg of hair for cocaine, 0.43–141 ng/mg of hair for benzoylecgonine and 0.93–1.83 ng/mg of hair for cocaethylene. All eight investigated cases had cocaine-positive segments. In six of the cases, all segments were positive, suggesting regular cocaine use and two showed in-between negative segments indicating an interruption or a change of the abuse intensity. The results showed a second, remarkable observation, i.e. enormous concentration differences (factor >150) for both cocaine and benzoylecgonine between the different subjects. Furthermore, interindividual cocaine/benzoylecgonine ratios ranged from 0.02 to 8.43. We believe these observations could in part be attributed to both some of the still existing limitations in the analytical approach(es), especially the mandatory hair washing steps, and in our still too limited knowledge of the hair incorporation processes. Nevertheless, in some cases, segmental analysis proved to be an important tool to distinguish, together with postmortem examination, deadly chronic abuse from single acute drug overdosage.     

Efficacy of an Intervention to Reduce the Use of Media Violence and Aggression: An Experimental Evaluation with Adolescents in Germany

Several longitudinal studies and meta-analytic reviews have demonstrated that exposure to violent media is linked to aggression over time. However, evidence on effective interventions to reduce the use of violent media and promote critical viewing skills is limited. The current study examined the efficacy of an intervention designed to reduce the use of media violence and aggression in adolescence, covering a total period of about 12 months. A sample of 683 7th and 8th graders in Germany (50.1% girls) were assigned to two conditions: a 5-week intervention and a no-intervention control group. Measures of exposure to media violence and aggressive behavior were obtained about 3 months prior to the intervention (T1) and about 7 months post-intervention (T2). The intervention group showed a significantly larger decrease in the use of violent media from T1 to T2 than the control group. Participants in the intervention group also scored significantly lower on self-reported aggressive behavior (physical aggression and relational aggression) at T2 than those in the control group, but the effect was limited to those with high levels of initial aggression. This effect was mediated by an intervention-induced decrease in the normative acceptance of aggression. No gender differences in program efficacy were found. The results show that a 5-week school-based intervention can produce changes in the use of media violence, aggressive norms, and behaviors sustained over several months.
