How do political parties divide coalition payoffs in multiparty governments? Perhaps the most striking answer to this question is Gamson’s Law, which suggests a strong fairness norm in the allocation of office payoffs among coalition partners. Building upon recent advancements in portfolio allocation research, we extend this approach in three important ways. First, we study fairness with regard to the allocation of policy (rather than office) payoffs. Second, we introduce measures to assess the fairness of the division of policy payoffs following two norms: envy-freeness and equitability. Third, we explore why some allocations of ministerial portfolios deviate from fairness norms. Based on an original data set of party preferences for individual portfolios in Western and Central Eastern Europe, we find substantial variation in the fairness of policy payoffs across cabinets. Moreover, coalitions are more likely to arrive at envy-free and equitable bargaining outcomes if (1) these fair allocations are based on an allocation of cabinet positions that is proportional to party size and if (2) the bargaining power is distributed evenly among government parties. The results suggest that fairness is not a universal norm for portfolio allocation in multiparty governments, but in fact depends on the cabinet parties’ bargaining positions.

Objective

Criminological research consistently demonstrates that approximately 5% of study populations are comprised of pathological offenders who account for a preponderance of antisocial behavior and violent crime. Unfortunately, there have been no nationally representative epidemiological studies characterizing the severe 5% group.

Materials and Methods

Data from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative sample of 43,093 non-institutionalized U.S. residents aged 18 years and older were analyzed using latent class analysis to assess sociodemographic, psychiatric, and behavioral characteristics.

Results

Four-classes of respondents were identified vis-à-vis lifetime externalizing behaviors. A normative class (66.1% of respondents) demonstrated little involvement in antisocial conduct. A low substance use/high antisocial behavior class (20.7% of respondents) and high substance use/moderate antisocial behavior (8.0% of respondents) class evinced diverse externalizing and psychiatric symptoms. Finally, a severe class (5.3% of respondents) was characterized by pathological involvement in more varied and intensive forms of antisocial and externalizing behaviors and extensive psychiatric disturbance.

Conclusions

The current study is the first nationally representative epidemiological study of criminal careers/externalizing behavior spectrum in the United States and validates the existence of the 5% pathological group demonstrated by prior research.  相似文献

The U.S. Supreme Court decisions in Daubert v. Merrell Dow Pharmaceuticals Inc. and Kumho Tire Co. Ltd. v. Carmichael transformed the way scientific expert evidence was reviewed in courts across the United States. To gauge the impact of these rulings on the admission of forensic identification evidence, the authors analyzed 548 judicial opinions from cases where admission of such evidence was challenged. Eighty-one cases (15%) involved exclusion or limitation of identification evidence, with 50 (65.7%) of these failing to meet the "reliability" threshold. This was largely because of a failure to demonstrate a sufficient scientific foundation for either the technique (27 cases) or the expert's conclusions (17 cases). The incidence of exclusion/limitation because of a lack of demonstrable reliability suggests that there is a continuing need for the forensic sciences to pursue research validating their underlying theories and techniques of identification to ensure their continued acceptance by the courts.  相似文献

The fight against doping is mainly focused on direct detection, using analytical methods for the detection of doping agents in biological samples. However, the World Anti-Doping Code also defines doping as possession, administration or attempted administration of prohibited substances or methods, trafficking or attempted trafficking in any prohibited substance or methods. As these issues correspond to criminal investigation, a forensic approach can help assessing potential violation of these rules. In the context of a rowing competition, genetic analyses were conducted on biological samples collected in infusion apparatus, bags and tubing in order to obtain DNA profiles. As no database of athletes' DNA profiles was available, the use of information from the location detection as well as contextual information were key to determine a population of suspected athletes and to obtain reference DNA profiles for comparison. Analysis of samples from infusion systems provided 8 different DNA profiles. The comparison between these profiles and 8 reference profiles from suspected athletes could not be distinguished. This case-study is one of the first where a forensic approach was applied for anti-doping purposes. Based on this investigation, the International Rowing Federation authorities decided to ban not only the incriminated athletes, but also the coaches and officials for 2 years.  相似文献

The U.S. federal budgeting system faces severe challenges in coming years. Deficits are being recorded at levels and with regularity not seen in prior periods. This article suggests that such problems reflect the uncomfortable mix of logics informing budgetary and political institutions—that is, the rules of the game. Logics make it appropriate to expect that government be limited in its tax demands but simultaneously responsive in providing expensive services necessary for the achievement of the American dream, for example. Crisis is needed to allow the emergence of institutional forms that mediate between these conflicting logics.  相似文献

The Influence of Foreign Voices on U.S. Public Opinion   总被引:1,自引:0,他引:1  
Public opinion in the lead‐up to the 2003 Iraq War presents a puzzle. Despite the fact that domestic political elites publicly voiced little opposition to the invasion, large numbers of Americans remained opposed to military action throughout the pre‐war period, in contrast to the predictions of existing theory. We argue that some rank‐and‐file Democrats and independents expressed opposition because of the widely reported antiwar positions staked out by foreign, not domestic, elites. Merging a large‐scale content analysis of news coverage with public opinion surveys from August 2002 through March 2003, we show that Democrats and independents—especially those with high levels of political awareness—responded to dissenting arguments articulated in the mass media by foreign officials. Our results, which constitute the first empirical demonstration of foreign elite communication effects on U.S. public opinion, show that scholars must account for the role played by non‐U.S. officials in prominent foreign policy debates.  相似文献
