Crime rates in many Latin American citiestend to be very high. But there is alsodiversity between and within cities. Regardless of whether the role ofdeterrence or those of poverty andinequality are emphasised as causes ofcrime, the use of aggregate data instatistical work may provoke seriousunobserved-heterogeneity biases. Diversity, divisiveness and heterogeneitymay also affect future trends, includingfurther vigilantism, official orsemi-official violence, segmentation,privatisation and ``medievalisation'. Thediscussion is completed by some ideas as tothe possibility that Latin America'spresent may be an accurate forecast ofEurope's future.  相似文献

Occasionally, partial calvariae of hydrocephalic calves are found in forensic contexts and mistakenly identified as human. Such specimens can be properly identified through immunological assessment of associated soft tissue, microscopic analysis of associated hair, and morphological comparison with documented museum specimens. Morphological comparison should focus on the form of the occiput, supraorbital grooves, and bulbous vault and presence of coronal processes.  相似文献

Cocaine and sudden "natural" death   总被引:4,自引:0,他引:4  
The cardiovascular effects of cocaine may culminate in clinical episodes of angina pectoris, myocardial infarction, arrhythmias, and intracranial hemorrhage. To clarify whether or not cocaine causes fatalities by these mechanisms, we studied 24 cases of sudden, apparently natural deaths as a result of coronary arteriosclerosis (15 cases), hypertensive cardiovascular disease (4 cases), and intracranial hemorrhage (5 cases) associated with cocaine use. In 11 cases, cocaine was found in the blood (average concentration: 0.57 mg/L, range: 0.05 to 1.45 mg/L), whereas in the remainder, cocaine or its major metabolite was found in the urine or other tissues. In the majority of decedents, autopsy disclosed the existence of severe natural disease which could have been exacerbated by the administration of stimulant drugs, including cocaine. These data, and a review of the current medical literature, indicate that cocaine may precipitate the sudden death of an individual with undiagnosed cardiovascular disease. A contributory role of cocaine should be considered in any apparently natural death occurring in a population where cocaine abuse is prevalent.  相似文献

东亚历史上曾先后建立以中国为中心的朝贡——华夷秩序以及以日本、美国为核心的霸权秩序,在以国家主权为国际关系核心机制的当代,这些反映不平等国家间关系的秩序无法复制到当今东亚,东亚的现实也决定了不存在孕育这些秩序的土壤。同时,20世纪80年代以来的全球化和区域经济一体化两种趋势极大程度地影响了当今东亚秩序的建构,然而一个统一的东亚秩序的建构又受到该地区复杂的大国关系的制约,东亚秩序将摇摆于“东亚”与“亚太”之间。  相似文献

In Alabaster v. Barclays Bank plc and Secretary of State for Social Security (No. 2: [2005] E.W.C.A Civ. 508, [2005] I.R.L.R. 576.) Michelle Alabaster won a grand total of £204.53 (plus £65.86 interest) after eight years of litigation, which included two visits to the Court of Appeal and one to the European Court of Justice. This marathon resulted from the sex discrimination which Alabaster had alleged in relation to the calculation of her Statutory Maternity Pay (S.M.P.) whilst she was pregnant 10 years earlier. The technicalities of the statutory schemes involved should not be allowed to disguise the important principle which finally emerges in the Court of Appeal and which underlines one of the longstanding criticisms of the equality legislation, namely the requirement that a woman must compare herself with a man in order to establish unlawful sex discrimination.  相似文献

This paper examines the issue of harmfulness of tax competition commenting on issues like welfare, growth, redistribution, harmonization and individual freedom. A simple game theoretical ap proach is formulated, where for the first time the two players start from unequal initial conditions, thus influencing strategy and outcomes. Next we propose the new criterion of Optimal Tax Area under which the possibility and feasibility of tax harmonization is examined. The policy implication of our paper is that we do not expect harmonization for direct taxes like corporate taxes in the EU in the near future and if so, harmonization of corporate tax rates on low levels. We conclude that both more theoretic research and empirical evidence are needed before we can answer with certainty whether tax competition is harmful or not. classification A1 . D6 . H0  相似文献

This study examined the quality or characteristics of permanent placements at 6 years of age for 254 children who had been removed from their homes prior to attaining 3.5 years of age (mean = 13 months). Although the primary objective when removing children is protection, subsequent permanent placements are prioritized by federal legislation with a stable family environment, especially one with the biological parent(s), being preferred. Three a priori comparisons (i.e., reunified vs. nonreunified, adopted vs. foster care, relative vs. nonrelative foster care) were conducted for caregiver and child reports of exposure to family violence. The results indicate that both reunified children and their parents report more family violence (witnessed and child victimization) than do nonreunified children and their caregivers. Adoptive parents did report that they used more minor violence in disciplining their children than did foster caregivers, but their children reported witnessing significantly less physical violence in the home. Recognizing that the development of children removed from their homes because of maltreatment is likely a function of both the maltreatment as well as the quality of subsequent family experiences (i.e., violence exposure), implications of the findings for determining placements are discussed.  相似文献

Ethics dilemmas have been present throughout the history of public health, and bioethics has devoted considerable attention to issues relevant to public health. Only recently, however, has public health ethics emerged as a recognized subfield of bioethics. Public health ethics requires that public health improvement come through just and respectful means. Bioethics in the future not only will take on more issues of public ethics, but will apply it extensive scholarship in distributive justice to questions of global public health.  相似文献

An underlying assumption in the nationwide policy shift toward transferring more juveniles to criminal court has been the belief that stricter, adult sentences will act as either a specific or general deterrent to juvenile crime. With respect to general deterrence—whether transfer laws deter would‐be offenders from committing crimes—it is important to examine whether juveniles know about transfer laws, whether this knowledge deters criminal behavior, and whether juveniles believe the laws will be enforced against them. The current study is one of the first to examine juveniles' knowledge and perceptions of transfer laws and criminal sanctions. We interviewed 37 juveniles who had been transferred to criminal court in Georgia, obtaining quantitative as well as qualitative data based on structured interviewed questions. Four key findings emerged. First, juveniles were unaware of the transfer law. Second, juveniles felt that awareness of the law may have deterred them from committing the crime or may deter other juveniles from committing crimes, and they suggested practical ways to enhance juveniles' awareness of transfer laws. Third, the juveniles generally felt that it was unfair to try and sentence them as adults. Finally, the consequences of committing their crime were worse than most had imagined, and the harsh consequences of their incarceration in adult facilities may have had a brutalizing effect on some juveniles. The implications for general and specific deterrence are discussed.  相似文献
