The paper by Gaudette and Keeping on "An Attempt at Determining Probabilities in Human Scalp Hair Comparison" in the Journal of Forensic Sciences (Vol. 19, No. 3, July 1974, pp. 599-606) has provoked considerable controversy. This paper highlights two of the sources of the controversy and shows how the probability, 1/4500, quoted by Gaudette and Keeping should be treated with caution. The necessity of the use of a likelihood ratio statistic is described. It is suggested that the hair examination form resulting from the responses to the questionnaire recently distributed by the authors and also the discussions at Quantico (Proceedings of the International Symposium on Forensic Hair Comparisons, 25-27 June 1985, Quantico VA) should be used to facilitate the collection of the data which will be necessary to enable a likelihood ratio statistic to be estimated effectively.  相似文献

This article is adapted from a paper presented at a conference that investigated the role of policy research in shaping public policy. The conference focused on how studies of economic and social forces and their relationship with public problems and programs affect the decisions of public policymakers. The author contends that research has the potential to inform policy-making in any of its five stages: problem identification, option development, passage of new laws or development of new procedures, implementation, and evaluation. She notes that different players in the policy-making process use research differently, from the senior government official who needs a quick review of what is known relating to a "hot" issue to the interest group lobbyist who wants access to raw data. The article concludes that research can best achieve its potential when (1) it anticipates policymakers' information needs, (2) it is disseminated in an accessible form understandable to nonresearchers, and (3) the policy analyst is willing to engage in the policy process as an advocate for efficiency.  相似文献

One of the important resources to any state, such as California, is the technology that is available from the many federally operated and/or funded laboratories within its borders. In this age of technology a state needs to take advantage of applications of modern technology and innovative exploitation of human and natural resources. This article illuminates the importance of the Federal Government research laboratories. Many examples are presented to support the argument that the Federal Government research laboratories can be and often are substantial contributors to the storehouse of technology that finds its way to the private sector and public sector. Several types of technology transfer are discussed, i.e. primary technology, secondary applications, mission related, technical assistance and cooperative. In addition the article discusses the structure and logic of the Federal Laboratory Consortium for Technology Transfer (FLC). The legislaltion that has helped to make the FLC effective is discussed. Included in the discussion are insights of how the FLC operates and how the private sector and public sector may use the FLC in order to locate process, product and service technology.  相似文献
