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

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

In many countries, monies suspected of being associated with drug trafficking can be seized by the authorities. One of the ways of investigating this association is through the analysis of seized banknotes for traces of controlled drugs. We report three studies which may assist the expert in assessing whether banknotes contaminated with diamorphine are part of the general population of notes in circulation or whether they show unusual contamination patterns which require explanation. Study 1 is based on three plausible contamination scenarios as they may occur during the various stages of an illicit drug transaction and seizure. It shows that notes which have been in direct contact with visible traces of diamorphine show significantly higher contamination to those in more indirect contact with the drug. Study 2 investigates the transfer of diamorphine from one highly contaminated note to other notes in a bundle over a period of 10 weeks with and without agitation. It was found that the total amount of drug transferred was smaller than 6% and no more than 4 out of a bundle of 10 previously clean notes became lightly contaminated. Based on extensive background data, study 3 proposes a probabilistic model to assess whether an observed proportion of diamorphine bearing banknotes is likely to have been contaminated by chance. The model predicts that there is only a 0.3% chance that a bundle of 100 notes from the general banknote population contains more than six contaminated specimens. Jointly, the three studies give useful indications for the spread of contamination throughout a sample and the amounts of heroin which may be expected given plausible contamination scenarios. 相似文献

A screening instrument for detecting intimate partner violence (IPV) was developed using indirect questions. The authors identified 5 of 18 items studied that clearly distinguished victims of IPV from a random group of health conference attendees with a sensitivity of 85% and a specificity of 87%. This 5-item instrument (SAFE-T) was then tested on 435 women presenting to three emergency departments and the results compared to a direct question regarding current abuse. The SAFE-T questions detected only 54% of the women who admitted being abused and correctly classified 81% of the women who said they were not victims. The 1-year prevalence of IPV in this sample of women presenting to an emergency department was 11.6%. The authors conclude that indirect questioning of women appears to be more effective at ruling out IPV in an emergency department population and may be less useful for women "early" in an abusive relationship. 相似文献

In an ideal world, there would be a seamless relationship between interventions that focus on risk factors causally associated
with sexual reoffending and the subsequent release of, and ongoing support for, offenders into the community. However, emotionally
fueled and uninformed public responses to news of released sex offenders, and the legislation such responses have inspired,
severely hinder this process. Our aims in this paper are to review findings of research on community attitudes about sex offenders
within a desistance framework. More specifically, we provide a synthesis of the current research literature on attitudes towards
sex offenders. Second, we consider in more detail those studies that include community member samples. Third, we review interventions
aimed at promoting attitude change amongst professionals working with sex offenders and finally formulate some recommendations
for promoting positive attitude change amongst the general public. 相似文献

Miranda vocabulary forms the essential foundation for Miranda comprehension and subsequent decisions to exercise or waive
Miranda rights. The purpose of the current study is the development of the Miranda Vocabulary Scale (MVS), designed to evaluate
key vocabulary words found in Miranda warnings and waivers across American jurisdictions. A preliminary list of MVS words
was refined by expert ratings and by each word’s discriminability between failed and good Miranda comprehension. Miranda and
other measures were collected at multiple sites on 376 pretrial defendants. With further refinements, the MVS is composed
of 36 words with excellent scale homogeneity and interrater reliability (r = .99). It also demonstrated good convergent and discriminant validity for cognitive abilities and psychological impairment. 相似文献
