Characterization and haplotype analysis of 10 novel Y-STR loci in Chinese Han population 总被引:3,自引:0,他引:3
Dai HL Wang XD Li YB Wu J Zhang J Zhang HJ Dong JG Hou YP 《Forensic science international》2004,145(1):47-55
In this study, we analyzed allelic sequences of 10 novel Y-specific STR loci, DYS454, DYS510, DYS513, DYS520, DYS542, DYS544, DYS552, DYS561, DYS587 and DYS593, surveyed the distribution of haplotypes in a Chinese Han population. Extracted DNA was amplified with PCR, followed by a horizontal non-denaturing polyacrylamide gel electrophoresis with discontinuous buffer system. Purified alleles were sequenced on DNA sequencer (ABI Model 377) to verify the number of motif repeats. The number of alleles observed at each locus ranged from 3 to 8, yielding 102 haplotypes in 103 unrelated males samples. The allele diversity values for each locus ranged from 0.2099 (DYS544) to 0.7523 (DYS552). The haplotype diversity using all these loci was 0.9998. Our study revealed that they were valuable Y-specific markers for forensic applications. 相似文献

劳动者参与治理:国有企业制度创新的基本路径 总被引:2,自引:0,他引:2
我国国有企业治理制度表现出来的劳动者权益缺损,根源于国有企业产权界定模糊,即以资本产 权逻辑排斥劳动力产权。应从“劳动努力”出发,通过劳动者参与治理来创新国有企业治理制度。 相似文献

This study explored the effects of judges' personal characteristics (gender, race, age, and political affiliation) and case characteristics on the outcomes of federal cases of hostile environment sexual harassment. Results revealed that even after controlling for the effects of relevant case characteristics (e.g., severity of the harassment), judges' personal characteristics influenced case outcomes. Specifically, younger judges and Democrat judges were more likely to find for the plaintiff (the alleged victim of harassment). The probability that the decision would favor the plaintiff was only 16% when the case was heard by an older judge but 45% when heard by a younger judge. The probability that the decision would favor the plaintiff was only 18% when the case was heard by a judge who had been appointed by a Republican president but 46% when the judge had been appointed by a Democrat president. 相似文献

A paper previously published in Law and Human Behavior by D. Davis and W. C. Follette (2002) argued that certain "profiling" characteristics commonly admitted into court have little or no probative value. They argued that this is especially likely to be true when the characteristic used as evidence (e.g., having an extramarital affair) is rather common in the population whereas the act in question (e.g., a man murdering his wife) is rare. Their analysis has prompted a strong response by Friedman and Park and by Kaye and Koehler with a rejoinder by Davis and Follette (all three follow this paper in this issue of Law and Human Behavior). This paper describes some of the nature of this controversy. 相似文献

Drug use in the workplace is a problem, both in terms of public health and expense. Workplace drug testing programs serve as deterrents to drug use. Model programs, such as that of the Department of Transportation, use urine screening and are federally regulated or follow federal standards. An essential participant in this process is the medical review officer (MRO), a licensed physician who interprets the laboratory results generated from a workplace drug testing program. As a result of their training and experience with toxicology, collection of evidence, testimony, and recognition of the physical signs of drug abuse, medical examiners and forensic pathologists are well suited to serve as MROs. Recent regulations require the completion of training courses and MRO certification as prerequisites for participation in federal drug testing programs. Several courses are available to train physicians to participate as MROs. 相似文献

Allele frequencies for the 15 STRs included in the AmpFlSTR SGM Plus and Profiler kit (D3S1358, VWA, D16S539, D2S1338, D8S1179, D21S11, D18S51, D19S433, THO1, FGA, TPOX, CSF1PO, D5S818, D13S317 and D7S820) were obtained from a sample of 597 unrelated individuals living in Taiwan. All loci, except for D8S1179 and D5S818, are in Hardy-Weinberg equilibrium. 相似文献

We provide a short overview on some current issues in the fields of forensic genetics and ancient DNA (aDNA) analysis. We discuss about the existence of the possible points of contact between the two disciplines, in terms of open problems and the inherent approach to their solution. We mainly focus on the problem of results authentication, its theoretical and technical aspects. 相似文献

This article considers the implications of assisted outpatient commitment laws (OPC), with specific focus on New York's "Kendra's Law" through the lens of therapeutic jurisprudence (TJ). In this article, the author offers perspectives on the relationship between involuntary civil commitment, outpatient commitment, and the concept of the "least restrictive alternative"; considers pertinent empirical research, and looks at OPC's controversial relationship to forced drugging. Here, the civil libertarian critique is briefly considered, as well as the MacArthur Research Network research. Finally, the author looks closely at Kendra's Law, providing a brief overview of the law itself, and identifying some "pressure points" and pivotal issues, and considers the TJ implications of Kendra's Law, to determine how it "fits" into the public's "take" on all of mental disability law. 相似文献
