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.

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

Family experiences are influential in the development of non-suicidal self-injury (NSSI). The current study aimed to identify specific dimensions underlying early parent–child relationships in association with NSSI. It was hypothesized that all relationship dimensions would be related with NSSI, with some dimensions being stronger predictors when accounting for shared variance. Gender differences were also assessed. Participants were grouped according to the endorsement of NSSI in the past 6 months, resulting in a Non-NSSI group (n = 1133) and a NSSI group (n = 105). Significant differences were found for the relationship dimensions between the two groups. When shared variance was accounted for, fear and alienation were the only dimensions predicting NSSI. Similar results were found for females (n = 887), while no analyses using males (n = 351) were significant. These results emphasize the need to acknowledge the role of parent–child relationships in prevention programs and intervention models for NSSI.  相似文献
