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 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

The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations. 相似文献

This paper argues that corruption is a product of self-aggrandizement; of unrealistically low remuneration which makes it impossible for public servants to live within their legitimate means; and of a closed political system which inevitably tends to exclude aggregated interests'. Corruption leads to loss of much needed revenue and human talent for development, distorts priorities for public policy, and shifts scarce resources away from the public interest. The mutual distrust that results among the different sections of society, and the growth of despondency in the general public, are incompatible with the requirements for successful public policy. The main theme running through the paper is that political instability, corruption and underdevelopment are mutually reinforcing. The paper finally outlines certain measures that need to be taken in order to clear the path for sustained growth and development. 相似文献

This article examines constraints in development bureaucracies in intensifying the use of microcomputers as they move beyond processing applications to analysing applications. The work is based on the experience of several ministries of the Government of Kenya. Processing applications involve throughput of data and are relatively simple. Analysing applications, in contrast, are more complex and include data assembly, sensitivity analysis, and modelling. The article argues that processing applications are more compatible with the administrative cultures, bureaucratic functions, personnel skill levels and organizational structures of development bureaucracies. Analysing applications are less compatible because they require a level of training and motivation uncommon in development bureaucracies. Analysing applications are further thwarted by constraints in the supply of relevant information and the lack of demand for analysis by decision-makers. A four-cell matrix is developed which explains these constraints. The article concludes with several recommendations for encouraging microcomputer-based analysis, but cautions that processing applications will continue to dominate for the foreseeable future. 相似文献
