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

The writings of Sir Bernard Spilsbury: Part I   总被引:1,自引:0,他引:1  
This is a two-part historical feature, highlighting the rare writings of Sir Bernard Spilsbury, the recognized leader of British forensic medicine in the first half of the 20th century. Parts I and II were compiled from the publications of the Medicolegal Society of Great Britain, where Sir Bernard Spilsbury served as President in 1933. Although his profile was presented previously in this Journal (vol. 2, no. 2, 179-182, 1981), it is felt that much of Sir Bernard Spilsbury's personality comes out in his writings and recordings of his speeches in the Medicolegal Society publications. Part I includes his lecture on "The Medico-Legal Significance of Bruises," presented before the Medicolegal Society in 1938; and a short case report read before the Medicolegal Society in 1924. The subject of the case report was sudden death from inhibition. Part II will contain two papers from the Medicolegal Society publications.  相似文献

Physicians who defraud and abuse medical benefit programs provide a unique group of lawbreakers for scientific study. They could be considered to epitomize white collar criminals given their exceedingly high socioeconomic status and power as a professional group. Using official reports and documents, as well as interviews with enforcement and program personnel at both state and federal levels, this study examines the problem of physician fraud and abuse in Medicare and Medicaid. Major areas relevant to understanding this phenomenon and its control are presented and policy implications of present knowledge in the area are discussed.  相似文献

The attention paid by the social work profession to ethical issues has waxed and waned since the formal inauguration of the profession in the late 19th century. For the first half century of the profession's life, relatively little attention was devoted to problems of professional ethics, though social work's literature was filled with discussions of value-laden issues that arise in practice. In recent years, interest in professional ethics has increased substantially. This article discusses the growth of interest in professional ethics, the formulation of the social work code of ethics, the adjudication of grievances in social work, and the strengths and limitations of the profession's code.  相似文献
