Population admixture (or ancestry) is used as an approach to gene discovery in complex diseases, particularly when the disease prevalence varies widely across geographic populations. Admixture analysis could be useful for forensics because an indication of a perpetrator's ancestry would narrow the pool of suspects for a particular crime. The purpose of this study was to use Fisher's information to identify informative sets of markers for admixture analysis. Using published founding population allele frequencies we test three marker sets for efficacy for estimating admixture: the FBI CODIS Core STR loci, the HGDP-CEPH Human Genome Diversity Cell Line Panel and the set of 39 ancestry informative SNPS from the Shriver lab at Pennsylvania State University. We conclude that the FBI CODIS Core STR set is valid for admixture analysis, but not the most precise. We recommend using a combination of the most informative markers from the HGDP-CEPH and Shriver loci sets. 相似文献

Manual recovery of spray paints from textiles using a microscope, the routine method in many laboratories, is often laborious. Beating the clothing with a plastic rod, the routine method used for recovery of glass traces within the authors’ laboratory, is proposed as an alternative. The efficiency of the method was evaluated by spray tests with fluorescent paint. In these tests, paint particles in the acquired debris samples, as well as those remaining on the textiles, were investigated. The results show that beating is an efficient way to recover and concentrate paint particles. A good efficiency for jeans fabric and rough knitwear is reported. The results appeared to be less satisfactory for smooth woven fabric. Application of the method in casework was effective for graffiti paints as well as for flaked car paint. 相似文献

There is an urgent need for consistent data sharing policies that promote the advancement of science while respecting the values and interests of those providing their genetic data for research. Responding to the article of Jalayne J. Arias, Genevieve Pham-Kanter, and Eric G. Campbell, ‘The Growth and Gaps of Genetic Data Sharing Policies in the United States’, this commentary further explores the challenges of human subjects’ protection in existing data sharing policies. We will elaborate on the need for data sharing policies to accommodate variation in individual and group preferences around data sharing and privacy concerns by comparing our previously published data on patients’ and parents’ consent to data sharing and attitudes about privacy to data from focus groups with HIV-positive, underserved individuals who were asked about their willingness to participate in genetic research and share their data broadly. These studies support the observation of Arias, Pham-Kanter, and Campbell that researchers, and funding agencies will need to balance the privacy interests of groups as well as individuals in future genomic data sharing policies. 相似文献

The purpose of this study was to explore the prevalence of substance abuse indicators in a sample of male sexual offenders (N = 679) and to examine the influence of adverse childhood experiences (ACE) on the likelihood of substance abuse outcomes. Half of these sex offenders reported a history of drug or alcohol abuse, and nearly one in five reported a substance-related arrest. Higher ACE scores were associated with endorsement of a greater number of substance-abuse-related problems, suggesting that accumulation of early trauma may increase the likelihood for substance misuse. By enhancing our understanding of the frequency and antecedents of dynamic risk factors such as substance abuse, we can better devise clinical interventions that respond to the comprehensive needs of sexually abusive individuals and reduce risk for sexual reoffense. As well, early interventions for at-risk families and maltreated youth may interrupt their trajectory toward adulthood substance abuse and criminal behavior, including sex offending. 相似文献

The twin forces of globalization and devolution have created administrative circumstances that strain the problem‐solving capacity of local governments and increase the importance of nongovernmental processes and institutions. The literature suggests that locally owned firms are more likely to engender higher levels of civic engagement critical to buttressing that problem‐solving capacity. This research adds an additional dimension, investigating to whom those firms sell and through which supply channels. Using survey results from hundreds of local firms across five study sites, this research demonstrates that locally facing firms—that is, firms that intentionally interface with community members and other local businesses—are associated with greater levels of civic and political engagement compared with locally owned firms that sell their products to customers elsewhere. Findings suggest that local governments should look beyond the local/nonlocal ownership binary to consider how private firms can be partners in serving and supporting their communities. 相似文献

Seven new generic Top Level Domain (gTLD) proposals were approved by the Board of the Internet Corporation for Assigned Names and Numbers (ICANN) at its Annual Meeting on 16 November 2000 for negotiation towards appropriate agreements between ICANN and the registry operator or sponsoring organization or both for registration and entry into the Domain Names System (DNS) including. biz for businesses. These seven, namely .info,. biz,. name,. pro,. aero,. coop and .museum , are the first new gTLDs, other than country code gTLDs to be added to the DNS since 1988. Appropriate agreements for all the new TLDs except .pro have been concluded and .biz is available for applicants for registration as a gTLD. The scope of this article is to examine the gTLD .biz against the background of electronic commerce (e-commerce) having regard to the factors leading to the introduction of this new gTLD, including certain problems or criticisms arising before and since the launch of .biz and, to consider whether .biz is likely to fulfil the claim of its registry operators, NeuLevel, that this new arrival is the best gTLD for the promotion of business on the world wide web. 相似文献
