OBJECTIVE: A cross-sectional study of gender specific relationships between self-reported child sexual abuse and suicidality in a community sample of adolescents. METHOD: Students aged 14 years on average (N = 2,485) from 27 schools in South Australia completed a questionnaire including items on sexual abuse and suicidality, and measures of depression (Centre for Epidemiological Studies Depression Scale), hopelessness (Beck Hopelessness Scale), and family functioning (McMaster Family Assessment Device General Functioning Subscale). Data analysis included logistic regression. RESULTS: In boys, self-report sexual abuse is strongly and independently associated with suicidal thoughts, plans, threats, deliberate self-injury, and suicide attempts, after controlling for current levels of depression, hopelessness, and family dysfunction. In girls, the relationship between sexual abuse and suicidality is mediated fully by depression, hopelessness, and family dysfunction. Girls who report current high distress about sexual abuse, however, have a threefold increased risk of suicidal thoughts and plans, compared to non-abused girls. Boys who report current high distress about sexual abuse have 10-fold increased risk for suicidal plans and threats, and 15-fold increased risk for suicide attempts, compared to non-abused boys. Fifty-five percent (n = 15) of sexually abused boys attempted suicide versus 29% (n = 17) girls. CONCLUSIONS: A history of sexual abuse should alert clinicians, professionals and carers in contact with adolescents, to greatly increased risks of suicidal behavior and attempts in boys, even in the absence of depression and hopelessness. Distress following sexual abuse, along with depression and hopelessness indicate increased risk of suicidal behavior in girls, as well as boys. 相似文献

Development,Dissemination, and Assessment of a Food Safety Systems Management Curriculum for Agribusiness Students in Armenia 下载免费PDF全文

This study addresses the development, dissemination, and assessment of a Food Safety System Management (FSSM) curriculum offered to college‐aged, agribusiness students in Yerevan, Armenia. Prior to beginning the program, demographic data were collected and a paper‐based pretest was administered to access the food safety knowledge, behavior, and attitude of participants (n = 29). For assessment of a skill, participants’ handwashing techniques were videotaped and scored before the program commenced. Immediately after completion of the entire curriculum, a paper‐based post‐test with identical questions for food safety knowledge, behavior, and attitude was administered and handwashing skills were assessed. ANOVA with repeated measures was used to evaluate significant differences (α = 0.05) for food safety knowledge using a pretest, post‐test, and a 3‐mo follow‐up. A paired t‐test was used to evaluate handwashing skills before and after the curriculum was presented. The pretest score (44.93%, ± 2.87) for food safety knowledge (n = 29) differed significantly (P <0.0001) when compared with the post‐test score (73.21%, ± 3.28) and the 3‐mo follow‐up (n = 23) score (67.76%, ± 3.93). Participants’ (n = 9) handwashing skills prior to delivery of the FSSM curriculum differed significantly (P <0.0001), when compared to handwashing skills after completion of the curriculum. Students’ food safety attitudes and behavior assessed using a five‐point Likert scale, also improved significantly as a result of the FSSM program. The 3‐mo follow‐up survey on food safety attitude and behavior was consistent with the post‐test survey results. The information from this project may be of interest to education experts, Extension professionals, food industry personnel, or regulatory agencies, in the development and dissemination of an international food safety program. 相似文献

This paper describes a five-phase practice approach that further develops Monsen et al.'s problem-analysis framework, which was originally designed for use by educational psychologists in training. The five-phase approach aims to provide a user-friendly conceptual framework for use by experienced educational psychologists. Action points, completed summary proformae, and a multi-faceted assessment and intervention example are provided to support the implementation of this approach within practice-based work. 相似文献

The challenges faced in urban science education are deeply rooted in the ongoing struggle for racial, class and gender equity. Part of this struggle is tied to huge differences in class and involves making more equitable the distribution of resources. Another part of this struggle is tied to the rich diversity of children who attend urban schools and involves generating new ways of understanding, valuing, and genuinely incorporating into school‐based practices the culture, language, beliefs, and experiences that these children bring to school. Thus, this article argues that to address these two challenges—and indeed to achieve a more just science education for all urban students— explicitly political research methodologies must be considered and incorporated into urban education. One potential route for this is critical ethnography, for this kind of methodology emerges collaboratively from the lives of the researcher and the researched and is centrally about praxis and a political commitment to the struggle for liberation and in defense of human rights. In making this argument, I have drawn from stories from my own research with homeless children. © 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 899–917, 2001 相似文献

In this paper, we explore the rationale, process and outcomes of the Regional Interoperability Project on Progression for Lifelong Learning, a project that established a model of cross‐sector collaboration in personal development planning technology in the UK. With specific reference to the widening participation agenda, and grounded in the perspective of lifelong learners, the project tested an approach in which discrete nodes of an individual’s learning journey are joined up through technology services. The paper describes the development of conceptual and practical tools to assist transitions between various communities of learning. A set of scenarios was developed, involving study to study and study to employment, while practical tools included development of UK LeaP draft interoperability standard (BS8788)‐compliant links between ePortfolio software, and the actual test transfer of data. The results indicate that recognising the smallest individual elements in the process is important, both in a technical sense and as a means of personalising learning and assisting transition between sectors. Through developing connections between these elements, the project partners engaged in lifelong learning. 相似文献

Critical race theory (CRT) emphasizes the importance of listening to the counter-narratives of people from marginalized groups. However, the applicability of CRT in practical settings often remains unclear for educators and scholars. This project offers not only a place for Native community members to share their experiences and ideas, it also provides practical guidance for emerging culturally responsive educators and ways to use themes from narratives to guide future scholarship. As a result of interviews with five Native community members, three themes emerged for non-Native educators working in Native communities: (a) learning from the community, (b) transforming thinking through discomfort, and (c) gaining awareness of positive values. These themes can be used to guide future projects, including reservation-based field experiences and research projects exploring educator thinking in reservation communities. 相似文献
