A validation study for the extraction and analysis of DNA from human nail material and its application to forensic casework. 总被引:5,自引:0,他引:5

A validation study was conducted to demonstrate that deoxyribonucleic acid (DNA) could be successfully extracted from human nail material and analyzed using short tandem repeat (STR) profiling and/or mitochondrial DNA (mtDNA) sequencing. This study involved the development of a DNA extraction protocol that includes a cleaning procedure designed to remove external contaminants (e.g., biological, chemical). This protocol was used to test human nail material that had been soaked in whole blood from a second donor and coated with gold-palladium to simulate scanning electron microscopic analysis. The results showed no indication of a mixture and were consistent with that of the nail donor. Fresh human nail material usually yielded both STR profiles and mtDNA sequence information; however, aged human nail material (approximately eight years old) yielded only mtDNA sequence information. Upon completion of the validation study, the extraction protocol was used for the analysis of a torn fingernail fragment recovered from the scene of a violent homicide in 1983. A partial STR profile and mtDNA sequence information indicated that the fingernail fragment was excluded as originating from the suspect and was, in fact, consistent with originating from one of the victims. 相似文献

The purpose of this article is to examine the self-reported sexual attitudes and behaviors of adolescents living in the Midwest. A survey was administered to 463 African American youths ages 11–19. The results indicate that intent to have sexual intercourse, reported likelihood toward having sexual intercourse, and whether participants felt that they would have sex in the next 3 months were predictors of whether they had sexual intercourse at the 3-month follow-up. The results also revealed that the opinions of referent others did not predict sexual intercourse at 3 months. Negative attitudes toward condoms did predict condom use at 3 months and the opinions of referent others also predicted condom use at 3 months. Limitations as well as future research are also discussed. 相似文献

Despite the recognition that the integration of refugees and expellees into west Germany has been one of the success stories of the post‐war period, little light has been shed on the process of political integration of this group into the political system of the nascent Federal Republic. As the ‘newcomers’ were prevented from organising themselves in political or cultural organisations, the only legitimate way of exercising political influence was the way through the licensed parties. The CDU/CSU as a conglomerate of liberal and conservative traditions made use of its historic opportunity to adapt its flexible party apparatus and encourage refugee participation. Thereby, it made an important contribution to the political representation of refugee demands as well as attracting a large proportion of the newcomers’ votes. 相似文献

Many law enforcement agencies are currently responding to the problem of online crime by establishing proactive investigative units that track criminals on the Internet. Not only do these specialized teams face problems in the area of emerging technology, they are also faced with handling emerging legal issues. The current research examined the issue of the entrapment defense, and how previously established physical realm doctrine could be applied to the investigation of online crimes such as child pornography. Relying on previous case law it would appear that entrapment claims related to online sting operations involve consideration of: a) did the law enforcement officer continuously contact the suspect with the intention of trying to convince the individual to engage in a particular type of behavior, b) how long was the relationship between the undercover officer and the suspect, and c) how much, if any, reluctance to commit the criminal act did the suspect provide evidence of? 相似文献

朝鲜的变化与中朝关系--从"传统友好合作关系"到"实利关系" 总被引:3,自引:2,他引:1
中国和朝鲜关系自1999年开始恢复,这虽不表示两国已恢复过去的同盟关系,但一定会对朝今后的发展起到积极作用.本文首先介绍中朝关系的变化;然后分析在向朝鲜提供改革模式及理念、经济资源、政治军事援助过程中,中国对朝鲜变化产生的影响;最后得出主要结论,即虽自20世纪90年代后期开始,朝中关系正式进入恢复阶段,但双方关系不再以共享理念和战略目标为基础,而是基于现实利益或战术目标.朝中关系这一新特点将继续制约中国对朝鲜变化过程的影响.此外,文章还针对朝鲜的发展变化,就中韩合作问题提出了若干建议. 相似文献

修订后的《中华人民共和国公司法》于2006年1月开始实施,其目的在于给投资者营造更为有利的法治环境,并进一步落实相关法律责任的追究与相关法律执行的透明度。新《公司法》将董事受信忠实的概念第一次引入到中国法中。受信概念源于普通法系中的衡平法系统,但普通法系统与衡平法系统在法学与管辖上并存之双轨制度在中国大陆法系中却不存在。本文将由此探究以单纯书面立法的方式引入衡平法中受信概念的可行性。本文认为,只要在这个概念被转化为一个法律概念前对其作出详尽的定义,受信理论的衡平法特性并不会真正阻碍其转化为我国的法律概念。为对上述观点作出阐释,文章以新《公司法》中禁止董事与公司进行自我交易这一具体规定为参照,结合案例讨论了通过对境外司法实践的借鉴、立法机关衡平法技巧的培养,以及更仔细地考察现行的国内法则,来帮助弥补单单引入一个空洞的受信概念不足的可能性。 相似文献

Zusammenfassung Seit einem Jahr liegen die thematische Strategie für den Bodenschutz und der Entwurf der Bodenrahmenrichtlinie vor, mit denen
die Europ?ische Kommission das europ?ische Umweltrecht komplettieren und einen nachhaltigen Umgang mit den Bodenressourcen
erreichen will. Jahrzehnte vorher hatten schon die Welt-Boden-Charta und die Europ?ische Bodencharta eine nachhaltige Bodennutzung
gefordert, um der anhaltenden Bodendegradation Einhalt zu gebieten. Vor 15 Jahren hatte die Weltgemeinschaft die Rio-Deklaration
über Umwelt und Entwicklung und einen Aktionsplan für diese Deklaration, mit denen nachhaltige Entwicklung, nachhaltige Ressourcennutzung
und nachhaltiger Bodenschutz umgesetzt werden sollen, vereinbart. Der Beitrag stellt die Strategie, die Rahmenrichtlinie und
den Diskurs zwischen den am Entscheidungsprozess beteiligten Organen und Interessenvertretungen von Landwirtschaft und Industrie,
der noch im Gange ist, dar. Auch werden einige Schlüsselthemen der Weiterentwicklung des Bodenschutzes, l?sungsbedürftige
theoretische Fragen, die im Hintergrund der Auseinandersetzungen stehen, skizziert. 相似文献

How did the Menzies Governments of the early to mid 1960s arrive at the position of sending Australian troops to Vietnam? During the 1950s, Menzies, and especially his External Affairs Minister Richard Casey, developed an appreciation of the strategic significance of Indochina, but struggled to view the conflict in Vietnam in ways other than through Cold War lenses. By the 1960s too, Britain's capacity to demonstrate a lead for Australia in foreign policy for the region was diminishing with its power, and the Menzies Governments were mindful of the need to support an American preparedness to intervene in Southeast Asia against communist‐led forces. This logic became more compelling in the face of Indonesia's “Confrontation” with Malaysia from 1963. As a result, the Liberals were not reluctant to support US military intervention in the region, in Vietnam. 相似文献
