Puberty has been related to the onset of a variety of weight concerns and eating problems among middle school girls, including body dissatisfaction, dieting, and eating disorders. At least two models can be used to explain these relationships. The first emphasizes the timing of puberty, arguing that girls who face early puberty are particularly stressed because of the off-time nature of the event. The second focuses on synchronous events. For girls more than boys, puberty is likely to coincide with the change from elementary to middle school and/or beginning to date. Such synchronous events may create greater stress for girls. Seventy-nine girls were tested during the spring of their sixth- and eighth-grade years. Pubertal and dating status, body dissatisfaction, weight management, and eating disordered attitudes (using the Children's EAT:ChEAT) were assessed. The simple timing model (early vs. on time vs. late) was not supported. The simple synchronous model received some support in that girls with synchronous onset of menstruation and dating had higher ChEAT scores as well as greater body dissatisfaction. However, the data indicated that girls for whom puberty was early and coincidental with dating might be at unusual risk. These girls showed the highest levels of body dissatisfaction and the highest ChEAT scores.Ph.D. from Temple University.

The purpose of the pilot study was to examine the interrelationship between social support, risk-level, and safety actions for 2 groups of suicidal adolescents (50 attempters and 50 ideators), who had presented for an acute assessment at an outpatient mental health service. A social support model was proposed in which it was thought that information related to patients' social support would impact upon the types of risk-level and safety actions made by clinicians. Data was collected from a total of 100 patient files, utilizing the acute assessment reports (e.g., reports assessing risk of self-harm). Findings show that groups differed significantly on indices of negative support severity, positive support, and risk-level. Limited support was found for the proposed social support model. Limitations and implications for future research are discussed. 相似文献

ABSTRACTIn 2017, following a fraught 22-year struggle, Israel appointed the first female judge (sing. qadiya, pl. qadiyat) to its Islamic (shari’a) courts. This contrasts with the earlier appointments of qadiyat around the world, most notably in the Palestinian Authority in 2009. The Israeli shari’a courts’ jurisdiction over family law, a field of law which engages in women’s issues, makes the introduction of qadiyat particularly salient. This article is among the first to focus academic research on the issue of qadiyat within Israel and is based on field interviews with practitioners and academic experts, as well as documentary primary and secondary sources. This article finds that the obstacles that delayed the appointment of Israel’s first qadiya were a manifestation of the political impact Muslim minority status had on the country’s Muslim and Jewish establishments. 相似文献

ABSTRACTMarked in part by a narrow river, the border between the neighbouring provinces of Loei in Thailand and Sayaboury in the Lao PDR appears to be porous and unregulated. While a Friendship Bridge regulates large-scale international trade, an extensive amount of informal, small-scale trade continues to flow across smaller checkpoints and other parts of the river. Trade along these sites is not only highly organised, most of it also happens under the gaze of border officials. This article examines the material and power exchanges that occur at local checkpoints between the different actors involved in the facilitation and restriction of trade. Between Loei and Sayaboury, trade is regulated according to a spectrum of licitness that is constantly negotiated and renegotiated between traders and officials. Negotiations rely on the social relations between these actors and involve practices of gift-giving and bribery, which blur the boundaries between reciprocity and corruption. By focusing on the interactions between state and non-state actors, this article sheds light on the way the informal economy is configured by checkpoint politics. 相似文献

This article reports an evaluation of a community intellectual disability offender service over the period from 1990 to 2001. Men who committed sex offenses or sexually abusive incidents (n = 106) and men who committed other types of offenses and serious incidents (n = 78) are compared on personal characteristics, referral sources, forensic details, and outcome up to 7 years after referral. The cohorts are older than one would expect from the criminology literature, and, at about 33%, the incidence of mental illness is consistent with some previous studies. A greater proportion of sex offenders had criminal justice involvement and a formal disposal from court. Fire raising was not overly represented as an offense. There was a higher rate of reoffending in the nonsexual cohort, which persisted up to 7 years. Investigating only reoffenders, there was a considerable amount of harm reduction recorded up to 7 years, statistically significant up to 5 years following initial referral. 相似文献

This study investigated to what extent abuse-related symptoms and family functioning are related to intra- or extrafamilial sexual abuse. One hundred adolescents (12 to 18 years old) were recruited shortly after disclosure of the abuse. Information from the participants was obtained through self-report questionnaires and a semistructured interview. Fifty-three percent of the adolescents reported clinically significant symptoms. Data did not support the idea that intrafamilial sexually abused adolescents report more symptoms than extrafamilial sexually abused adolescents. Type of abuse did not account for the differences and variety of reported symptoms or for differences in family functioning. Family functioning-in particular, lack of cohesion- was an independent contributor to internalizing trauma-related problems. 相似文献

This study examined effects of clothing cues on children's identification accuracy from lineups. Four- to 14-year-olds (n = 228) saw 12 video clips of individuals, each wearing a distinctly colored shirt. After watching each clip children were presented with a target-present or target-absent photo lineup. Three clothing conditions were included. In 2 conditions all lineup members wore the same colored shirt; in the third, biased condition, the shirt color of only one individual matched that seen in the preceding clip (the target in target-present trials and the replacement in target-absent trials). Correct identifications of the target in target-present trials were most frequent in the biased condition, whereas in target-absent trials the biased condition led to more false identifications of the target replacement. Older children were more accurate than younger children, both in choosing the target from target-present lineups and rejecting target-absent lineups. These findings suggest that a simple clothing cue such as shirt color can have a significant impact on children's lineup identification accuracy. 相似文献

This paper addresses research in the life sciences, responsible for significant national expenditures for scientific investigations funded by both the federal government and industry. Our investigation examines faculty members' involvement with industry in entrepreneurial ways that is, involved in translating their research into potentially marketable knowledge or products. First, this study examines whether there are differences in entrepreneurial behaviour between clinical and non-clinical faculty in the life sciences with industry relationships, and, second, to discover any linkage between entrepreneurship and secrecy or productivity in different ways for clinical and non-clinical faculty. The study is based on survey responses of a national sample of 4,000 clinical and non-clinical life sciences faculty in 49 U.S. research universities. The results show non-clinical faculty as more involved at the back end. The more entrepreneurial end of commercialization while clinical faculty are involved at the back end. The more entrepreneurial faculty (non-clinical) are more likely to be secretive about their research. Clinical faculty are less likely to have been denied access to research results or products. Entrepreneurial faculty are not less productive in their faculty roles. This investigation is preliminary in that it addresses one large area of academic research but excludes fields with longer historical relationships with industry. 相似文献
