The Spanish and Portuguese ISFG Working Group (GEP-ISFG) carried out a collaborative exercise in order to asses the performance of two Y chromosome STR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The groups that reported correct results in all the systems were also asked to analyse a population sample in order to evaluate the informative content of these STRs in different populations. A total of 1020 males out of 13 population samples from Argentina, Brazil, Costa Rica, Macao, Mozambique, Portugal and Spain were analysed for all the loci included in the present study. Haplotype and allele frequencies of these eight Y-STRs were estimated in all samples. The lowest haplotype diversity was found in the Lara (Argentina) population (95.44%) and the highest (99.90%) in Macao (China). Pairwise haplotype analysis showed the relative homogeneity of the Iberian origin samples, in accordance with what was previously found in the European populations for other Y-STR haplotypes (http://www.ystr.org). As expected, the four non-Caucasian samples, Macao (Chinese), Mozambique (Africans), Costa Rica (Africans) and Argentina (Lara, Amerindians), show highly significant Phist values in the pairwise comparisons with all the Caucasian samples. 相似文献

Variation in the timing of pubertal maturation may result in behavioral differences among early, mid-, and late maturers. Using data from the National Health Examination Survey, a national probability sample of children and youth aged 12–17, we investigated the relationships between maturational timing and body image, school behavior, and deviance. In terms of body image, the early maturing boys were the group most satisfied with height and weight. The early maturing girls were most dissatisfied with weight, with 69% wishing to be thinner. This great dissatisfaction with weight reported by early maturing girls is probably not an affect of early maturation, but a concomitant of maturation in general. The majority of girls became dissatisfied with their weight as they matured, and females from the higher social groups were more likely to want to be thinner than females from lower groups. Thus, a normal developmental process is being viewed negatively by females and positively by males. Male early maturers more often had deviant behavior, but there were no consistent findings for girls. There was no effect of maturational timing on teacher reports of school absence, adjustment, popularity, need for discipline, or grade repetition.This research was supported by the Stanford Center for the Study of Youth Development and by the Robert Wood Johnson Foundation.Received M.D. from The Medical College of Pennsylvania.Received Ph.D. in anthropology from Stanford University.Received Ph.D. in sociology from the University of Chicago.Received M.D. from Columbia College of Physicians and Surgeons.Received Ph.D. in psychology from Harvard University. 相似文献

Youth who are homeless and gay, lesbian or bisexual (GLB) are one of the most disenfranchised and marginalized groups in our
society. The purpose of this study is to examine and compare HIV in GLB homeless youth with their heterosexual counterparts.
Participants for this study included 268 youth involved in treatment outcome studies with substance abusing homeless youth.
Results suggest that GLB youth have greater HIV risks and that these risks are greater among bisexual females. In examining
the predictors of sexual health risks, survival sex emerged as the most significant. Survival sex was high among females regardless
of their sexual orientation and also among gay males. Implications of these findings suggest that a greater emphasis needs
to be paid to preventive interventions among this population.

Julianne Serovich, Ph.D., is Professor and Chair in the Department of Human Development and Family Science, The Ohio State University. She received
her Ph.D. in 1991 from the University of Georgia. Her primary program of research centers on investigating the role of HIV
disclosure to family and friends in reducing sexual risk related behaviors in men and mental health outcomes in women. To
this end she has conducted 3 major studies investigating HIV disclosure behaviors in gay males, and heterosexual males and
females. 相似文献

Although a growing body of research has focused on identifying the characteristics of effective interventions, relatively little research has looked at the impact that staff factors have on treatment effectiveness. The current research conceptualizes staff quality via three domains: staff characteristics, staff training, and staff supervision. Process and outcome evaluations of 54 community correctional facilities are used to examine the relationship between staff quality and reduced recidivism of program participants. The results suggest that measures of all three domains maintain substantively meaningful relationships with program effectiveness. 相似文献

Abstract: A pilot study evaluated a computer‐based method for comparing digital dental images, utilizing a registration algorithm to correct for variations in projection geometry between images prior to a subtraction analysis. A numerical assessment of similarity was generated for pairs of images. Using well‐controlled laboratory settings, the method was evaluated as to its ability to identify the correct specimen with positive results. A subsequent clinical study examined longitudinal radiographic examinations of selected anatomical areas on 47 patients, analyzing the computer‐based method in making the correct identification based upon a threshold level of similarity. The results showed that at a threshold of 0.855, there were two false negative and two false positive identifications out of 957 analyses. Based on these initial findings, 25 dental records having two sets of full mouth series of radiographs were selected. The radiographs were digitized and grouped into six anatomical regions. The more recent set of films served as postmortem images. Each postmortem image was analyzed against all other images within the region. Images were registered to correct for differences in projection geometry prior to analysis. An area of interest was selected to assess image similarity. Analysis of variance was used to determine that there was a significant difference between images from the same individual and those from different individuals. Results showed that the threshold level of concordance will vary with the anatomical region of the mouth examined. This method may provide the most objective and reliable method for postmortem dental identification using intra‐oral images. 相似文献

The Labour Together review of the 2019 election brings together polling data, survey data, interviews, and submissions from across the Labour movement. An unpopular leader, tensions around the Brexit position, and a manifesto which was not seen as credible, are all found to have contributed to the scale of the defeat, but Labour’s unexpectedly strong performance in 2017 also masked long-term issues in its connection with the electorate and within the party’s campaign organisation. The report attempts to move beyond simply diagnosing the difficulties the party faces, but some of the thorniest issues for the party to resolve are nonetheless left unresolved. 相似文献

The Association of South East Asian Nations (ASEAN) escalated its community building project significantly over the last decade, culminating in the launch of a reformed and substantially integrated ASEAN Community at the end of 2015. This article considers what might follow from this newly reformed and rhetorically people-focused version of ASEAN for matters of sexual orientation and gender identity and expression (SOGIE). In claiming to be people-oriented and people-centred, and by developing a regional rights regime, ASEAN opens itself to standards by which it can be measured and held to account. We critically review ASEAN 2025: Forging Ahead Together, and consider civil society's response, focusing on the critique offered by the ASEAN SOGIE Caucus, the peak civil society organisation for ASEAN SOGIE matters. We focus on three themes: identity, visibility politics, and rights. We argue that while ASEAN falls short of its own rhetorical standards, these same standards support a politics which keeps rights in contestation, enabling civil society to push for accountability to international standards, and a more democratic politics. 相似文献
