A particular subtype of learning disability (nonverbal learning disability) is described. This subtype of individuals with learning disability is seen to be at particular risk for depression and suicide. The origins of the study of this subtype of learning disability, its incidence in various forms of neurological disease, disorder, and dysfunction, and its behavioral and socioemotional manifestations (including its association with significant internalized forms of psychopathology) are described. A case history of a young woman who manifests this disability and who has attempted suicide on three occasions is also presented.  相似文献

With the high prevalence of college students experiencing psychological distress, it is becoming increasingly important to provide prevention and early intervention programs in addition to traditional psychological counseling services. This study examined the effectiveness of a suicide prevention program led by peer educators/trainers on a diverse college campus. Twenty-five suicide prevention workshops were conducted with 479 attendees. Preworkshop and postworkshop assessments revealed significant improvements in participants’ knowledge of suicide and resources. Recommendations for campus-wide suicide prevention efforts using diverse peer educators that reflect the students’ demographic and cultural background, recruitment strategies, and utilization of outreach programming in suicide prevention.  相似文献

Science education reforms worldwide call on teachers to engage students in investigative approaches to instruction, like inquiry. Studies of teacher self-reported enactment indicate that inquiry is used frequently in the classroom, suggesting a high level of proficiency with inquiry that would be amenable to inquiry reform. However, it is unclear whether the high frequency of self-report is based on sound knowledge inquiry. In the absence of sound knowledge, high rates of self-reported enactment would be suspect. We conducted a study to measure teachers’ knowledge of inquiry as it related to the known, high frequency of reported enactment. We developed a multidimensional survey instrument using US reform documents and administered it to 149 K–12 teachers at a national science teachers’ conference. The majority of the teachers surveyed did not report inquiry enactment based on well-structured knowledge of inquiry. Interviews with participants showed how teachers could readily map non-inquiry activities onto inquiry statements taken directly from reform documents. From these results we argue that teachers often believed they were enacting inquiry, when likely they were not. We further reason that teachers may struggle to interpret and enact inquiry-related requirements of science education reform and will need support distinguishing inquiry from non-inquiry practices.  相似文献

School governing bodies in England have considerable powers and duties, and their formal role positions them as decision-makers. This article draws on qualitative research in the governing bodies of four maintained schools. Using deliberative democracy as a sensitising concept, the article considers some processes by which decisions are made (or not made) in governing bodies. Without claiming that governors never make decisions, it explores constraints and limitations on their ability to do so. Governors exhibit a paradoxical combination of busy-ness and passivity. On the one hand, governing bodies are constituted and structured around activity and technically decisions were made. On the other, decisions could rarely be attributed to active choices by governors. Rather, their more passive agreement with actions and positions was presented as almost unavoidable ‘common sense’, either due to the national policy context or the headteacher’s presentation of the available options.  相似文献

Previous research has shown that response rates on a variable interval (VI) schedule of reinforcement decrease if a brief response-produced signal is given prior to reward. One explanation is that the signal overshadows the response because it is a better predictor of reinforcement. The S-R overshadowing effect does not occur with variable ratio (VR) schedules, however. Tarpy, Lea, and Midgley (1983) explained this fact by suggesting that the signal functions to enhance the salience of the temporal interval offset on the VI schedule (a characteristic not possessed by VR schedules), which then overshadows the response. In this experiment, the salience of the temporal interval was enhanced in another way: signaled or unsignaled reward was provided to rats responding on either a VI or fixed interval (FI) reward schedule. As predicted, rates were lowest for animals receiving signaled reinforcement on an FI schedule and highest for those receiving unsignaled reinforcement on a VI schedule.  相似文献
