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

The individuality of fibres used to provide forensic evidence--not all blue polyesters are the same.
Fibres used in forensic casework suffer from a disadvantage common to other forms of trace evidence--it is not possible to state with absolute certainty that they originate from a specific source. Target fibre studies, population studies and research on 'blocks of colour' have effectively demonstrated the polymorphism of textile fibres (particularly man-made ones) and have shown that when a fibre is believed to have a specific putative source, the chance that it has originated from a different source purely by coincidence is extremely remote. A study by Houck MM (Houck MM, Inter-comparison of unrelated fibre evidence. Forensic Science International 2003; 135: 146-149) has shown that no coincidental matching fibres were recovered from items of clothing examined in 20 unrelated crimes. The study involved over two million comparisons. This work goes a step further, and using the example of blue polyester fibres shows that even within a very narrow segment of the whole general fibre population, many examples of a specific colour/type of man-made fibre taken from random sources can be compared and the chance of any two being the same is very low. These studies should help to show the specificity and value of transferred fibres in providing forensic evidence. 相似文献

Legal context: The relatively informal agreements setting up the TrilateralCooperation (TC) among the world's three most important patentoffices are contrasted with formal multinational treaties suchas the Patent Law Treaty and the abortive Substantive PatentLaw Treaty. Key points: After its inception in 1983, the TC concentrated initially ondeveloping and implementing standards for electronic storageand retrieval of prior art documents, and facilitation of searching.This was later extended to electronic sharing of priority documentsand to standardization and searching of DNA sequence databases.More recently emphasis has been placed on harmonization of searchingand examination procedures, and working groups have comparedthe approaches of the Trilateral Offices (TOs) to the patentabilityof claims in areas of new technology. Encouragingly, the resultsare usually the same, although the specific objections raisedmay differ. The ultimate goal is to reach a situation in whicha claim allowed by one TO would be accepted by the others withoutfurther examination. Practical significance: The TC has already facilitated search and examination, leadingto lower costs and shorter pendency times than would otherwisebe the case. Further progress depends on harmonization of substantivepatent law, which in turn depends on the willingness of theUSA to accept a first-to-file system. 相似文献

测谎技术是一种现代高科技的产物,我们既不能绝对排斥其在民事审判中的应用,使其游离于民事诉讼程序之外,也不能将其“神化”,将其视为冲破民事诉讼僵局的刹手锏。任何对案件事实的判断都要遵循基本的证明规律,如何在民事诉讼程序中理性地规范地运用测谎技术判断证据,不仅需要立法上进一步完善,也需要我们进一步深入地探索。 相似文献

新时期党和国家对邓小平历史地位的确认,经历了一个逐步发展的过程。从党的十一届三中全会到党的十二大以前,确认邓小平在党和国家的领导核心地位;从党的十二大到邓小平逝世以前,确认邓小平作为中国社会主义改革开放和现代化建设总设计师的地位;从邓小平逝世到现在,确认邓小平在党和国家乃至世界历史上的伟人地位。这个过程折射出新时期党和人民艰辛的探索历程。现在,我们就是要高举邓小平理论和“三个代表”重要思想的伟大旗帜,全面贯彻落实科学发展观,紧密团结在以胡锦涛为总书记的党中央周围,为全面建设小康社会,实现社会主义现代化而努力奋斗。 相似文献

我国物权立法中规定集体所有权的思考 总被引:3,自引:0,他引:3
正在讨论中的《物权法》(草案)对集体所有权作了规定,奠定了集体所有权立法的基础,但其距离集体财产关系的法律调整要求还有很大差距,各个条文自身仍存在着一定的缺陷。在《物权法》中应对集体所有权作一般原则规定,集体所有的具体制度应由专门法律规定。 相似文献

Divorce, although a statistical norm, is a developmental trauma to the children involved. This article looks at the two-camp emotional environment of a divorcing family and its effect on the formation of a child's identity. By examining developmental ages, chosen according to divorce research, the author attempts to show how the interspouse emotional cathexes negatively affect a child's sense of self in ways specific to the child's age at the divorce. 相似文献
