The interstate compact as a policy tool has a long history ofuse in the United States. Yet some observers feel that interstatecompacts have never lived up to their potential. Nevertheless,in 1980, the compact was chosen as the policy instrument tosolve one of the thorniest environmental policy issues of thedecade: the siting of low-level radioactive waste (LLRW) disposalfacilities. Drawing from research on interstate compacts andon alliance theory developed in international relations, thisarticle applies five key questions to the case of LLRW: Whydo states join compacts? Which compacts will they join? Howstable are the compacts? How important are outside factors?What types of situations are compacts most suited to address?It concludes with lessons that should be useful to future policymakersabout the use of interstate compacts to solve salient, nationwidepolicy problems.  相似文献

Singapore is an island state with no formal lower tier of government. The network of consultation and mobilization created after Independence in 1959 is now raising important issues of consensus and compliance. Twenty-five years of continuous one-party rule offer opportunities to evaluate the working of the mechanisms of integration and participation. In the late 1980s the highly urbanized, multi-ethnic society is placing new demands on the government, and questions of decentralization and feedback are high on the political agenda.  相似文献

This article gives an overview of current pharmacological treatment of paraphilias and sex offenders focusing on the situation in Germany. Information about selective serotonin reuptake inhibitors (SSRI) is followed by data about established antihormonal substances (cyproterone acetate/CPA, and medroxyprogesterone acetate/MPA), as well as a more detailed account on luteinizing hormone-releasing hormone agonists (LHRH agonists). The results of open, uncontrolled clinical studies with SSRIs (n = 16) and LHRH agonists (n = 11) in paraphilic outpatients confirm the positive effects of these substances. A survey about the use of CPA and LHRH agonists in forensic hospitals in Germany shows that half of the patients treated with any kind of (anti-) hormonal agents received an LHRH agonist. The authors present a protocol on side effects, contraindications, and monitoring of CPA and LHRH agonists and develop an algorithm for differential pharmacotherapy of paraphilias.  相似文献

The relationship between subjective invulnerability and optimism bias in risk appraisal, and their comparative association with indices of risk activity, substance use and college adjustment problems was assessed in a sample of 350 (M age = 20.17; 73% female; 93% White/European American) emerging adults. Subjective invulnerability was measured with the newly devised adolescent invulnerability scale (AIS). Optimism bias in decision-making was assessed with a standard comparative-conditional risk appraisal task. Results showed that the danger- and psychological invulnerability subscales of the AIS demonstrated strong internal consistency and evidence of predictive validity. Subjective invulnerability and optimism bias were also shown to be empirically distinct constructs with differential ability to predict risk and adjustment. Danger invulnerability and psychological invulnerability were more pervasively associated with risk behavior than was optimism bias; and psychological invulnerability counter-indicated depression, self-esteem and interpersonal problems. Results support recent claims regarding the “two faces” of adolescent invulnerability. Implications for future research are drawn.  相似文献

The versatility of isotope ratio mass spectrometry is demonstrated by reference to diverse case studies. Variations in the natural isotopic composition of non-biological, organic materials are compared as a means by which samples may be associated or discriminated. These techniques may be used to augment or compliment conventional forensic methodologies. delta13C analysis was used to demonstrate that different masking tape had been recovered in two, apparently similar cases, involving the smuggling of money. Visually similar ecstasy tablets were compared by consideration of the delta13C and delta15N composition of MDMA extracted from the tablets. Although only a limited number of tablets were analysed, the isotopic similarity between two different seizures was sufficient to induce a guilty plea from a person suspected of possessing both. A combination of delta2H, delta13C, delta15N and delta18O together with GC-MS analyses were applied to small samples of seized heroin. Although GC-MS analysis indicated differences between the chemical composition of two of the heroin samples, isotopic analysis suggested similarities, which were confirmed by further delta2H, delta13C and delta18O isotopic analysis of the clingfilm in which the samples were wrapped.  相似文献
