Little research has examined the structure and prevalence of attention-deficit/hyperactivity disorder (ADHD) symptoms in university students, including whether symptom structure conforms to the bidimensional (i.e., inattention and hyperactivity-impulsivity) conceptualization of the Diagnostic and Statistical Manual of Mental Disorders (DSMV-IV; American Psychiatric Association, 1994) and whether self-reported symptoms vary across gender and country. A sample of 1,209 university students from three countries (Italy, New Zealand, and the United States) completed a 24-item self-report measure (the Young Adult Rating Scale) tapping ADHD symptomatology. Factor analyses within the U.S. and New Zealand samples supported a bidimensional symptom structure, whereas weaker support for this conceptualization was provided by the Italian sample. Participants did not vary significantly by gender in symptom report; however, Italian students reported significantly more inattention and hyperactivity-impulsivity symptoms than students from the United States, and students from New Zealand reported more inattention symptoms than students from the United States. The prevalence of self-reported ADHD symptoms beyond DSM-IV thresholds for diagnosis ranged from 0% (Italian women) to 8.1% (New Zealand men). The implications of these results for the use of DSM-IV criteria in identifying university students with ADHD are discussed. 相似文献

The purpose of this study was to examine the effectiveness of two professional development models in increasing family child care providers’ frequency of linguistic inputs in conversations with young children. The first professional development model consisted of a 10-h in-service training focused on supporting early language development. The second included the same 10-h in-service training program and mentoring. Providers and children at 48 family child care programs participated in this study. The family child care programs were randomly assigned to one of the two professional development models (i.e., training or training with mentoring) or to a control group. Audio recordings of the language environment were collected prior to the in-service training, at the completion of the in-service training, and at the completion of the mentoring. Hierarchical linear modeling was used to examine the average increase in the frequency of providers’ use of linguistic inputs over three observations, conducted before training, immediately at the end of training, and 6 weeks after training. Results indicate that both forms of professional development increased linguistically stimulating inputs as compared to the control group. The professional development model including mentoring support was related to greater increases in providers’ use of informational talk and teaching utterances over in-service training without mentoring. 相似文献

This article aims to describe the general framework of the teacher training system and its recent reform in Japan. As elsewhere, Japanese society is moving into an era of mass higher education provision. Since initial teacher training is provided by universities, the reform of teacher training is a part of the higher education restructuring that is also under way. At the same time, Japan is facing educational problems in compulsory education. The Educational Personnel Training Council of Japan is recommending reforms, which attempt to create a new type of teacher to cope with these educational problems. This opens the way for the Japanese state to develop more direct control over the curriculum and assessment of teaching staff in universities. The Ministry of Education is attempting to develop new control methods of 'Evaluative State' strategies. The reform of teacher education system exemplifies this shift. 相似文献

Guided by affective events theory, the purpose of this study was to examine the temporal aspects of childcare teacher burnout, particularly as to how feelings of exhaustion throughout the day relate to perceptions of end-of-day job satisfaction and quitting intentions. A secondary purpose of the study was to explore the frequency and type of rejuvenation strategies childcare teachers use to relieve perceived stress throughout the day. Ecological momentary assessment procedures were employed for 1 week to assess exhaustion levels (3 times/day), frequencies and types of rejuvenation strategies (3 times/day), and end-of-day job satisfaction perceptions and quitting intentions (1 time/day) among 50 childcare teachers. Results indicated that childcare teachers’ quitting intentions were positively predicted by emotional exhaustion (β?=?0.52) and negatively predicted by overall job satisfaction (β?=??0.28). Short (≤15 min), infrequently used (one to two times/day) physical or cognitive health reprieve strategies were reported by 86?% of teachers as the most effective for reducing daily stress. Findings suggest that daily accounts of burnout and quitting intentions have both exhaustive and restorative properties. 相似文献

Spheroids that are formed from aggregated cells have enhanced biological function compared to individual cells. In particular, hetero-spheroids composed of different types of cells, such as hepatocytes and endothelial cells, express tissue specific functions at a high level, which is advantageous for more precise drug screening and biological research. In this study, we propose rapid formation of size-controlled three-dimensional hetero-cell aggregates consisting of hepatocytes and endothelial cells using micro-rotation flow. Based on previous data, these aggregates are expected to ultimately become hetero-spheroids. The hepatocytes are coated with collagen gel films less than 200 nm thick, which were experimentally verified to increase adhesion strength between hepatocytes and endothelial cells. Gel-coated hepatocytes and endothelial cells are collected in an array by micro-rotational flow, thereby forming hetero-cell aggregates within 2 min. This array allowed the size of the three-dimensional cell aggregates to be hydrodynamically controlled, with standard deviations of less than 19%, by varying the cell density of the medium without altering the device geometry. Endothelial cells were successfully and uniformly dispersed in the aggregates. The proposed microfluidic device, with its capability of rapidly forming size-controlled hetero-cell aggregates, will offer an efficient experimental platform for future hetero-spheroid study that will contribute to drug screening and regenerative medicine. 相似文献
