This paper uses historical content analysis to examine the implementation ofthe Racketeer Influenced Corrupt Organizations Act (RICO). It is argued thatthe historical events leading to the definition of organized crime as an alienconspiracy still affect RICO's use some 30 years after its passage. This paper applies state-centered theory to the theoretical frameworks of sociology of knowledge and innovation diffusion. This approach is used to relate the current implementation and controversy of RICO to the alien conspiracy view. Thought of in this context, legal implementation is the result of a knowledge creation and diffusion process. This paper demonstrates how one knowledge diffusionprocess (the acceptance of organized crime as a national conspiracy in 1970) leads to a new knowledge diffusion process (the use of RICO).  相似文献

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 article provides an editorial introduction to the following three related articles on the growing use and influence of social science research in family law. It first considers why this has become problematic and identifies some common strategies used by advocates, sometimes under the guise of scholarship, to destroy the standing of research findings contrary to their ideological or political position. Then it discusses briefly the remedies proposed to mitigate these kinds of problems within the following three articles.  相似文献

From a conflict resolution perspective, it is clear why the child support guidelines are not going to reduce the adequacy and compliance gaps in child support payment conflicts between parents. As it stands, the conflict over equally sharing child support is destructive rather than positive. The guidelines do not reframe the conflict for the parents, enabling them to believe the interests of children are more important than their own interests to win the child support battle. To transform conflict from destructive to positive, the elements of conflict–expression of the conflict, scarce resources and rewards, and interdependency–must be transformed. It is argued that the guidelines do not transform the conflict but facilitate it. Courts and attorneys are also significant players in the child support conflict.  相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.  相似文献

Using international data for 100 countries, we test two hypotheses derived from Bonger's Marxian theory of crime. The analyses support the hypothesis that the degree of capitalism significantly predicts homicide rates, but they fail to confirm that the de‐moralization of the population (loss of moral feelings for others) mediates the relationship between capitalism and homicide. Although capitalism is not the best predictor among those considered, overall, the results underline the importance of Bonger's ideas because both capitalism and corruption (our indicator of de‐moralization) show reasonably strong relationships with homicide rates and compete with other variables commonly used as predictors of international homicide rates. The results confirm the usefulness of attempting to subject Marxian ideas to positivist, quantitative tests, with an eye to integrating Marxian theories with other mainstream theories, such as institutional anomie theory.  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
