Restriction fragment length polymorphism (RFLP) analysis for the purpose of individualization is now being used in casework in the People's Republic of China. This report describes the use of the multilocus minisatellite probe 33.15 to solve three cases, including two homicides and a rape. In the third case, fetal tissue was analyzed to prove that the alleged rapist was, in fact, the father. In each case, analysis of deoxyribonucleic acid (DNA) resulted in a positive match. The probability of chance association of the DNA fingerprint was calculated as 5.6 x 10(-12), which is similar to the figures reported in the literature. 相似文献

This research note critically evaluates conventional methods for allocating homicides with an unknown victim/offender relationship to meaningful categories, and it proposes an alternative approach. We argue that conventional methods are based on a problematic assumption, namely, that the missing data mechanism is “ignorable.” As an alternative to these methods, we propose an imputation algorithm derived from a log‐multiplicative model that does not require this assumption. We apply this technique to estimate levels of homicides disaggregated by victim/offender relationship using the Federal Bureau of Investigation's Supplementary Homicide Report (SHR) data for 1996 and 1997, and we compare the resulting estimates with those obtained from the application of conventional procedures. Our results yield a larger proportion of stranger homicides than are obtained from the conventional methods. 相似文献

After the Agreement on the Trade-Related Aspects of Intellectual Property Rights (TRIPS) came into operation in 1995 developing countries have found themselves in a process of continual negotiation over intellectual property rights and access to medicines. These negotiations have taken place in the World Trade Organization and in the context of free trade agreements. The paper suggests that the only real win for developing countries has been the Doha Declaration on the TRIPS Agreement and Public Health in 2001. What have been the lessons for developing countries in a decade of negotiations over access to medicines? Drawing on themes of rule complexity and regulatory ritualism the paper discusses four key lessons for developing countries. It concludes by arguing that developing countries will do better if they adopt a networked governance approach to negotiation rather than continuing to rely on traditional coalition formation. 相似文献

During the past few decades traditional state‐centred governing arrangements have been critiqued and replaced by alternative modes of governance. Higher education is one of the public sectors where such shifts in governance have been seen. As a consequence of the reshuffling of authority and responsibilities across the different levels in Dutch higher education, universities as organizations have become important foci of attention in the system’s coordination. The main question addressed in this article is to what extent we can speak of an organizational transformation of Dutch universities. Based on conceptual ideas from researchers such as Greenwood and Hinings (1996), Ferlie et al. (1996) , and Brunsson and Sahlin‐Andersson (2000) , we use a framework that focuses attention on the concepts of the construction of identity, hierarchy and rationality to systematically analyse the various aspects of transformations of professional organizations. 相似文献

This paper explores the multi-layered representations of violence and crime in the recent Hollywood film Gangs of New York [Scorcese (2003) Miramax]. We use our exploration of this film to suggest that popular culture, even through its most mainstream products, can be seen as a critical criminological space where alternative views of law, crime and the state are made available. Rather than understanding Hollywood movies simply as vehicles for disseminating conventional mores, we suggest that they can furnish critical (and complex) points of view on law and crime and that the project of a critical criminology can be strengthened by engaging more forthrightly with these ubiquitous cultural forms. 相似文献

Drawing on the strategic surprise, warning-response, and foreign policy literature, this article argues that the September 11 terror attacks should be regarded as a strategic surprise and examines a number of key factors that contributed to vulnerability and inhibited vigilance. Three broad explanatory "cuts" derived from the literature—psychological, bureau-organizational, and agenda-political—are deployed to sift through the rapidly expanding empirical record in an effort to shed light on the processes and contextual factors that left the United States vulnerable to the attacks. The article aims to improve our understanding of generic processes and practices that enhance or detract from vulnerability and vigilance. 相似文献
