In the present study, we demonstrate that two commonly used Y-chromosome single nucleotide polymorphisms (SNPs), P25 and 92R7, are paralogous sequence variants (PSVs) originating from segmental duplications and that at least one of the sequence variants in each group of loci is polymorphic. Several methodologies were used in order to detect the SNP alleles and the PSVs of the loci. All results obtained with the various typing techniques supported the conclusion. The allele distributions of the binary markers were analysed in more than 600 males with seven different haplogroups. For P25, the ancestral allele C was found in several samples from different haplogroups. The derived allele A was always present with an additional C variant. Haplogroup P was defined by the derived allele A at the 92R7 locus. However, the ancestral allele G was always associated with an A variant due to the duplication. 相似文献

Following a recent meeting by the ENFSI and EDNAP groups on the 4-5 April, 2005, in Glasgow, UK, it was unanimously agreed that the process of standardization within Europe should take account of recent work that unequivocally demonstrated that chance of obtaining a result from a degraded sample was increased when small amplicons (mini-STRs) were analysed. Consequently, it was recommended that existing multiplexes are re-engineered to enable small amplicon detection, and that three new mini-STR loci with alleles <130 bp (D10S1248, D14S1434 and D22S1045) are adopted as universal. This will increase the number of European standard Interpol loci from 7 to 10. 相似文献

Surveillance images from a bank robbery were analyzed and compared with images of a suspect. Based on general bodily features, gait and anthropometric measurements, we were able to conclude that one of the perpetrators showed strong resemblance to the suspect. Both exhibited a gait characterized by hyperextension of the leg joints, and bodily measurements did not differ by more than 6 mm on average. The latter was quantified by photogrammetry: i.e., measuring by using images of the perpetrator as captured by surveillance cameras. Using the computer software Photomodeler Pro, synchronous images from different cameras were compared and concurrent body features were identified. The program could then render the perpetrator as a three dimensional, high-precision, scalable and measurable object. 相似文献

A collaborative study was carried out by the European DNA Profiling Group (EDNAP) in order to evaluate the performance of Y-chromosome binary polymorphism analysis in different European laboratories. Four blood samples were sent to the laboratories, to be analysed for 11 Y-chromosome single nucleotide polymorphisms (SNPs): SRY-1532, M40, M35, M213, M9, 92R7, M17, P25, M18, M153 and M167. All the labs were also asked to submit a population study including these markers. All participating laboratories reported the same results, indicating the reproducibility and robustness of Y-chromosome SNP typing. A total of 535 samples from six different European populations were also analysed. In Galicia (NW Spain) and Belgium, the most frequent haplogroup was R1b*(xR1b1,R1b3df). Haplogroup F*(xK) is one of the most frequent in Austria and Denmark, while the lowest frequency appear in Belgium. Haplogroup frequencies found in this collaborative study were compared with previously published European Y-chromosome haplogroup data. 相似文献

Surface Curvature of Pelvic Joints from Three Laser Scanners: Separating Anatomy from Measurement Error 下载免费PDF全文
Chiara Villa Ph.D. Daniel Gaudio Ph.D. Cristina Cattaneo M.D. Ph.D. Jo Buckberry Ph.D. Andrew S. Wilson Ph.D. Niels Lynnerup M.D. Ph.D. D.M.Sc. 《Journal of forensic sciences》2015,60(2):374-381
Recent studies have reported that quantifying symphyseal and auricular surface curvature changes on 3D models acquired by laser scanners has a potential for age estimation. However, no tests have been carried out to evaluate the repeatability of the results between different laser scanners. 3D models of the two pelvic joints were generated using three laser scanners (Custom, Faro, and Minolta). The surface curvature, the surface area, and the distance between co‐registered meshes were investigated. Close results were found for surface areas (differences between 0.3% and 2.4%) and for distance deviations (average <20 μm, SD <200 μm). The curvature values were found to be systematically biased between different laser scanners, but still showing similar trends with increasing phases/scores. Applying a smoothing factor to the 3D models, it was possible to separate anatomy from the measurement error of each instrument, so that similar curvature values could be obtained (p < 0.05) independent of the specific laser scanner. 相似文献

Recent research has illustrated that demographic diversity influences the outcomes of public sector organizations. Most studies have focused on workforce diversity; by comparison, little is known about how managerial diversity affects organizational outcomes. This article focuses on gender diversity in the top management teams of public organizations and its relationship to financial performance. Theory suggests that management diversity can be a positive asset for organizations, allowing for the use of more diverse knowledge and human skill sets. Results of this study, however, suggest that organizations may only be able to leverage these advantages if they have a supporting management structure. In a longitudinal study of top management teams in Danish municipalities, the authors find that gender diversity in top management teams is associated with higher financial performance, but only in municipalities with a management structure that supports cross‐functional team work. These results are interpreted in light of existing theory, and implications are suggested. 相似文献

ABSTRACTWhy do more men than women vote for populist radical-right (PRR) parties? And do more men than women still vote for the PRR? Can attitudes regarding gender and gender equality explain these differences (if they exist)? These are the questions that Spierings and Zaslove explore in this article. They begin with an analysis of men's and women's voting patterns for PRR parties in seven countries, comparing these results with voting for mainstream (left-wing and right-wing) parties. They then examine the relationship between attitudes and votes for the populist radical right, focusing on economic redistribution, immigration, trust in the European Union, law and order, environmental protection, personal freedom and development, support for gender equality, and homosexuality. They conclude that more men than women do indeed support PRR parties, as many studies have previously demonstrated. However, the difference is often overemphasized in the literature, in part since it is examined in isolation and not compared with voting for (centre-right) mainstream parties. Moreover, the most important reasons that voters support PRR parties seem to be the same for men and for women; both vote for the populist radical right because of their opposition to immigration. In general, there are no consistent cross-country patterns regarding gender attitudes explaining differences between men and women. There are some recurring country-specific findings though. Most notably: first, among women, economic positions seem to matter less; and economically more left-wing (and those with anti-immigrant attitudes) women also vote for the PRR in Belgium, France, Norway and Switzerland; and, second, those who hold authoritarian or nativist views in combination with a strong belief that gays and lesbians should be able to ‘live their lives as they choose’ are disproportionately much more likely to vote for PRR parties in Sweden and Norway. Despite these findings, Spierings and Zaslove argue that the so-called ‘gender gap’ is often overemphasized. In other words, it appears that populist radical-right parties, with respect to sex and gender, are in many ways simply a more radical version of centre-right parties. 相似文献
