Gardnerella vaginalis (GV) infection has been reported as being acquired via sexual contact in adults and as an indicator of sexual contact in female children (DeJong, 1985). The purpose of this study was to determine if GV infection was more commonly found in 191 female children who gave a history of sexual contact and/or were infected with Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) (Group 1), compared with 144 female children evaluated for possible sexual abuse and found to have no such history or infection with GC or CT (Group 2), or 31 female children (friends of the authors) without such a history or GC or CT infection (Group 3). Vaginal GV was found in 5.3% of Group 1, 4.9% of Group 2 and 6.4% of Group 3 (p > .05). Also, vaginal GV infection was not related to the type of sexual contact or race, but did increase with age in white female children. Because vaginal GV infection is not more commonly found in children with a history of sexual contact than those without such a history, the finding of GV in a vaginal culture in an individual case would not be a reliable marker of sexual contact. Routine culturing for GV is not recommended as part of a sexual abuse workup.  相似文献

We suggest that academics involved in the provision of research experiences to undergraduate science students may benefit by reconceptualising these experiences as work-based learning. In particular, drawing on the widespread use of reflective practice in work-based learning allows for a more effective focus on process-related learning. We describe an empirical study involving the implementation of reflective blogs in which science students responded to prompt questions designed to focus their attention on how their project was progressing, the process of research and their own learning. The blogs reveal examples of students engaging in independent thinking, creative thinking and developing a sense of themselves as scientists, all qualities valued by supervisors. They also show how these combine as ‘wicked competences’ that allow students to address the complex problems and uncertainties of research. We identify characteristic patterns of reflection that indicate the exercise of such competences and suggest that these could be used as explicit evidence by academics making judgements for assessment purposes.  相似文献

The contribution of attachment, maternal reported stress, and mother-child interaction to the prediction of teacher-reported behavior problems was examined for a French-Canadian sample of 121 school-age children. Attachment classifications were assigned on the basis of reunion behavior with mother when the children were between 5 and 7 years of age. Maternal reported stress and mother-child interaction patterns were assessed concurrent to the attachment measure, whereas behavior problems were evaluated both at ages 5 to 7 and 7 to 9 years. Security of attachment significantly predicted the likelihood of school-age behavior problems: Controlling/other children were most at risk for both externalizing and internalizing problems across both age periods. Younger ambivalent children presented clinical cut-off levels of externalizing problems, and older avoidant boys had higher internalizing scores. Patterns of maternal-reported stress and mother-child interaction differed across attachment groups and contributed to prediction of school-age behavior problems, partially mediating the relation between attachment and adaptation. Results support the importance of attachment in explaining school-age adaptation and validity of attachment coding for children of this age.  相似文献

There is increasing emphasis in higher education on preparing students for the workplace and recognising the learning that occurs in the workplace. Workplace learning has been exemplified in aspects of traditional courses by work experience, practicum, sandwich courses and practice‐based courses. Recently, however, academic attention has focused on the development of subjects and degree programs that are entirely workplace‐based. Such programs are negotiated with organisations to meet their own learning needs and promote the learning of individual company employees in the performance of their everyday work. Workplace‐based courses have developed in response to employer demand, restricted government funding for higher education and the need for universities to appeal to new markets. These factors have created a context of considerable tension between traditional academic practice and beliefs, and those that accompany this new approach. These tensions present challenges for universities as they attempt to respond in ways that maintain rigour and integrity while meeting the demands created by contemporary economic, political and social pressures.  相似文献

This study examined the relationship of perfectionism with measures of achievement and achievement motivation and mental health aspects of depression and self‐esteem in high school students. Participants were 123 tenth‐ through twelfth‐grade students. Results of multiple regression analyses indicated that students' personal standards were significant predictors of academic achievement. Students' personal standards also significantly predicted achievement motivation. Analyses of the relationship between perfectionism and depression and self‐esteem found that as students' personal standards increased, their levels of depression decreased and self‐esteem increased. Furthermore, when students experienced a discrepancy between their personal standards and actual performance, their depression levels increased and self‐esteem decreased. © 2000 John Wiley & Sons, Inc.  相似文献

A sample of 118 predominantly European American families with early and middle adolescents ( M ages= 12.32 and 15.18 years) and 1 parent evaluated hypothetical conflicts between adolescents' and parents' requests for assistance versus the other's personal desires. Evaluations differed by level of need, but in low-need situations, adolescents viewed teens as more obligated to help parents than did parents, whereas parents rated it as more permissible for teens to satisfy personal desires than did teenagers. Justifications for helping focused on concern for others, role responsibilities, and among parents, psychological reasons. Middle adolescents reasoned about role responsibilities more and viewed satisfying personal desires as less selfish than did early adolescents, but satisfying personal desires was seen as more selfish by parents of middle than early adolescents. Implications for adolescent–parent relationships are discussed.  相似文献

The objective was to investigate the relationship between IL-1B rs16944, IL-6 rs1800795, and CASP8 rs3834129 genetic polymorphisms and concussion severity. Rugby players from high school, senior amateur, and professional teams completed a concussion severity questionnaire and donated a DNA sample. Participants (n = 163) were split into symptom severity groups around the median number and duration of symptoms. The frequency of participants with high symptom counts (more than five symptoms) increased across the IL-1B (C/C: 35%; C/T: 51%; T/T: 56%; P = 0.047) and the IL-6 (C/C: 31%; C/G: 44%; G/G: 58%; P = 0.027) genotypes. The C–C inferred interleukin allele construct frequency, created from combining the IL-1B and IL-6 genotype data, was lower in participants reporting a high symptom count (18%), compared to those with a low symptom count (fewer than six symptoms, 36%, P = 0.002). Similarly, the C–C inferred interleukin allele construct frequency was lower in those reporting prolonged symptom duration (more than one week, 16%), as opposed to short symptom duration (less than one week, 34%, P = 0.015). This study provides evidence of novel inflammatory pathway genetic associations with concussion severity, which supports the hypothesis implicating neuroinflammation in the development of concussion symptoms.  相似文献
