Abstract The expansion of the security agenda after the end of the Cold War, propelled by the blowback of 11 September 2001, raises questions about the German ability and willingness to contribute to the regional and global security governance tasks facing Europe and Germany's continuing fidelity to its post-war European avocation. It also calls for a reconsideration of the Birmingham model of foreign policy analysis, particularly its emphasis on (and interpretation of) the ideational and institutional factors defining the German foreign policy agenda and shaping German foreign policy behaviour, at least with respect to the implementation (rather than formulation) of European Union security policies. Towards assessing the continuing utility of the Birmingham model, this article proceeds in three steps: the presentation of the Birmingham model and its restatement as six conjectures; a discussion of the security governance functions undertaken by the EU and the collective action problem facing Europe (and Germany) in executing them; and an empirical investigation of Germany's contribution to the EU as a security actor since 1990. 相似文献

Abstract This paper reports data from a content analysis of television news coverage of terrorism. A proposed typology of terrorism and media coverage is tested with stories from network news in the United States and Canada. The typology posits that media coverage of terrorism depends on the act's relation to institutional power bases. The two types of terrorism outlined either seek out or avoid media coverage, depending on whether they challenge or reinforce institutional power. Because of media's interrelationship with the economic and political institutions, coverage of terrorism will take on the flavor of these institutions’ perspective. The data show that although media cover terrorist acts that are linked to U.S. institutional interests, the tone of such coverage casts uncritical perspective. The implications for the general message system of news, with particular regard to the media's contribution to international understanding, are explored. 相似文献

Bath salts are new designer drugs with stimulant effects on the central nervous system. White or brown powder sold online and in mini‐marts under different brand names, bath salts can be used by injecting, snorting, smoking, or ingesting with food or drink. The case of a 30‐year‐old Caucasian male who developed acute psychosis within a few hours of injecting himself with bath salts is described. The patient was hospitalized with a complaint of hearing voices. The drug also induced in the patient a state of euphoria, increased energy level, along with decreased need for sleep and decreased appetite. The psychological effects of the bath salts subsided within a few hours of injection and his reality testing remained consistently intact over the next 3 days of hospitalization. This case brings to attention the fact that bath salts were legal throughout the United States until recently and is still not completely controlled. This report informs clinicians of harmful effects of bath salts, including severe agitation with possible rhabdomyolysis, psychosis, suicidal ideation, hypertension, tachycardia, and death. 相似文献

The majority of microfluidic devices used as a platform for low‐cost, rapid DNA analysis are glass devices; however, microchip fabrication in glass is costly and laborious, enhancing the interest in polymeric substrates, such as poly (methyl methacrylate) (PMMA), as an inexpensive alternative. Here, we report amplification in PMMA polymerase chain reaction (PCR) microchips providing full short tandem repeat profiles (16 of 16 loci) in 30–40 min, with peak height ratios and stutter percentages that meet literature threshold requirements. In addition, partial profiles (15 of 16 loci) were generated using an ultrafast PCR method in 17.1 min, representing a ~10‐fold reduction in reaction time as compared to current amplification methods. Finally, a multichamber device was demonstrated to simultaneously amplify one positive, one negative, and five individual samples in 39 min. Although there were instances of loci dropout, this device represents a first step toward a microfluidic system capable of amplifying more than one sample simultaneously. 相似文献

A relatively recent development in the comparative criminology literature concerns cross‐national comparisons of criminal sentencing practices (e.g., Lynch, 1993). While there are now several studies comparing sentencing practices and lengths, there is a particular shortage of studies that examine the disposition of serious criminal cases through several stages of the criminal justice process. Specifically, there is a shortage of information concerning this issue in Russia and the former Soviet Union. To address this limitation, we present data on the police and court disposition of violent criminal cases in the former Soviet Union during the period of 1986 to 1990. For comparative purposes, comparable data from recent studies of criminal case dispositions in the United States are presented. Implications of the findings are discussed. 相似文献
