Male interscholastic swimmers (n = 8) completed a 4572 m training swim in 62 ±1.1 min (x ± s.e.) with terminal heart rate and blood lactate of 152 ± 6 beats min‐1 and 6.9±0.89 mM, respectively. Sweat rate (0.48±0.0951. h‐1) was lower than similar intensity cycling (1.5±0.13 1. h‐1) or running (1.1 ± 0.14 l.h‐1). Post‐swim serum urea N (11.6±0.71 mM) was elevated (P<0.05) vs pre‐swim (4.6±0.39 mM). Post‐swim urine volume (860±75 ml 24 h‐1) was reduced (P<0.07) and resulted in an elevated (P<0.05), but delayed (24–84 h), post‐exercise urea N excretion. Although the reduced urine and sweat production during the swim undoubtedly contributed to the elevated serum urea, there must be another explanation because together they could only account for 38% of the observed increase. On the basis of the magnitude of serum urea increase, it appears that the swim caused an increase in urea production (amino acid oxidation). The failure to observe larger increases in urinary urea during recovery indicates that either urea excretion following exercise continues for prolonged periods of time (>48 h) or another significant mode of nitrogen excretion exists.  相似文献

This paper reports the findings of a project—‘Lifelong learning and teacher education’—undertaken by the Centre for Lifelong Learning, Australian Catholic University, under the auspices of the Australian Commonwealth Department of Education, Science and Training. The study was designed to investigate the operationalization of lifelong learning in Australian teacher education. The study revealed that there is a range of existing, innovative practices regarding partnerships between schools and higher and further education that are in keeping with emerging ideas about lifelong learning. Moreover, some of these take the form of collaborative action research projects focused on improving the learning occurring in the partnership schools. This paper describes some current approaches in Australia to collaborative action research by teacher educators' and their partnership schools and shows how they contribute to lifelong learning. The approaches are then analyzed to suggest ways of advancing lifelong learning within Australian Education Faculties thus helping to make lifelong learning more of a reality for all.  相似文献

Predoctoral interns' responses to an internship supervision training questionnaire indicated that counseling center interns supervised more trainees, received more supervision in their supervisory roles, reported more supervision training activities, and yielded higher supervisor development scores than did non‐counseling‐center interns. A qualitative analysis of participants' responses showed that non‐counseling‐center interns desired more supervision training and opportunities to provide supervision during their internship year than did counseling center interns.  相似文献

One set of measures of the quality of courses for the preparation of science teachers stems from the perceptions exit students have of their knowledge with respect to that teaching. The Discipline Review of Teacher Education in Mathematics and Science surveyed these students late in 1988 on three broad types of knowledge-science content knowledge, curriculum knowledge, and pedagogical knowledge. Some of these findings of the Review are described. In addition, the base for developing items to measure these three types of knowledge is discussed in this paper. The variety in the data that emerged is also presented and the consistency of the findings with other measures of quality is described. Specialisations: science and technology curriculum, environmental education, educational disadvantage. Specialisations: research and evaluation in teacher education, technical and further education and total quality management. Specialisations: research in educational systems.  相似文献

Data were collected from 289 undergraduate college students at a minority‐serving institution to explore the impact of academic rational beliefs on grit and resilience. Findings from hierarchical regression analyses suggested that academic rational beliefs related to evaluation and work habits accounted for a significant amount of variance in grit. Work habits explained a significant portion of the variance in resilience. On the basis of these results, recommendations for future research and implications for college counselors are offered.  相似文献

This study investigated the impact of different aspects of the circle of friends (CoF) intervention. A naturalistic sample of 14 primary‐aged children with a range of special educational needs were involved, seven of whom were followed‐up a term later, to assess medium‐term impact. The whole‐class meeting was found to be effective in increasing the social inclusion of the focus children. However, with the exception of one child with an autistic spectrum disorder (ASD), the weekly CoF meetings produced no measurable further improvements. Possible explanations for the pattern of findings and implications for educational psychology practice are discussed.  相似文献

This study examined whether differences in waist circumference (WC) and pedometer placement (anterior vs. midaxillary vs. posterior) affect the agreement between pedometer and observed steps during treadmill and self-paced walking. Participants included 19 pairs of youth (9–15 years old) who were matched for sex, race, and height and stratified by WC (high WC: HWC; low WC: LWC). Participants performed 3-min treadmill-walking trials at speeds of 59, 72, and 86 m·min-1 and a 400-m self-paced walking trial on level ground. Bland-Altman plots were used to assess the agreement between pedometer and observed steps of spring-levered pedometers by WC, pedometer placement, and walking speed. In the HWC group, the posterior pedometer placement consistently agreed most closely with observed steps at all treadmill speeds and during self-paced walking. In the LWC group, no single pedometer placement consistently agreed most closely with observed steps at all treadmill speeds and during self-paced walking. We conclude that a posterior pedometer placement improves step-count accuracy in most youth with an HWC at a range of walking speeds on level ground.  相似文献

Supportive communication was examined as a component of mothers’ sex discussion with children. Results demonstrated that mothers who communicated supportively were more open and disclosing when discussing sex and were more likely to provide sons with birth control information and instruction than mothers who communicated nonsupportively. The study concludes by raising several issues for future research and sex education pro‐ams for parents.  相似文献
