Interpreting small quantities of DNA: the hierarchy of propositions and the use of Bayesian networks
The dramatic increase in the sensitivity of DNA profiling systems that has occurred over recent years has led to the need to address a wider range of interpretational problems in forensic science. The issues surrounding questions of the kind "whose DNA is this?" have been the subject of considerable controversy but now it is clear that the emphasis is shifting to questions of the kind "how did this DNA get here?" Such issues are discussed in this paper and new insights are provided by two particular recent developments. First, the notion of the "hierarchy of propositions" that has arisen from a project called Case Assessment and Interpretation (CAI) that has been running in the British Forensic Science Service (FSS). Second, a technique for drawing inferences in the face of many interacting considerations, known as "Bayesian networks"--or "Bayes' nets" for short--that has been the subject of an earlier paper in this journal (1). The discussion is carried out by means of case studies, based on actual cases. It is clear that, whereas the inference in relation to the source of the DNA in a crime sample might be overwhelmingly strong, the inference in relation to the propositions that a jury must consider relating to the identity of the actual offender may be much more tentative. 相似文献

Latent lip print test results produced by permanent lipsticks are presented in this work. This cosmetic product, contrary to conventional lipsticks, does not leave visible prints and can thus be overlooked at the crime scene. As print vehicles the study used ceramics, glass, cotton fabric and paper. Lip prints were left to dwell for different periods and were later developed using aluminum powder, cobalt oxide powder and magnetic powder. The results show that identifiable lip prints can be obtained up to 30 days after being produced. 相似文献

近几年来,在文件鉴定过程中涉及变造文件鉴定的案件数量呈逐年上升趋势,越来越引起广大文检工作者的重视。文件物证的变造事实不仅具有一定的隐蔽性,发现难度大;而且对变造文件的检验需要进行综合性、系统性分析,检验难度也大。本文作者结合自己多年的检案实践,总结了检验变造文件的一些经验与体会,以期供广大同行共同研究探讨。 相似文献

在医疗纠纷的解决过程中,医疗事故鉴定成为其中争议很大的一个环节。在有关医疗事故的民事赔偿诉讼中,医学鉴定公正性受质疑,医学鉴定实际上被规避,诉讼效率降低,当事人的诉讼负担在一定程度上也有所加重。本文拟通过对医疗纠纷法医学鉴定和医学鉴定程序的比较,寻求两种鉴定程序的异同,并进一步提出司法鉴定机构介入诉讼中医疗事故鉴定的设想,通过改变目前诉讼中医学会专属鉴定的现状,缓和目前医疗纠纷民事赔偿诉讼中的一些矛盾。 相似文献
