This study investigated the effect of a single session of resistance exercise on postprandial lipaemia. Eleven healthy normolipidaemic men with a mean age of 23 (standard error = 1.4) years performed two trials at least 1 week apart in a counterbalanced randomized design. In each trial, participants consumed a test meal (1.2 g fat, 1.1 g carbohydrate, 0.2 g protein and 68 kJ x kg(-1) body mass) between 08.00 and 09.00 h following a 12 h fast. The afternoon before one trial, the participants performed an 88 min bout of resistance exercise. Before the other trial, the participants were inactive (control trial). Resistance exercise was performed using free weights and included four sets of 10 repetitions of each of 11 exercises. Sets were performed at 80% of 10-repetition maximum with a 2 min work and rest interval. Venous blood samples were obtained in the fasted state and at intervals for 6 h postprandially. Fasting plasma triacylglycerol (TAG) concentration did not differ significantly between control (1.03 +/- 0.13 mmol x l(-1)) and exercise (0.94 +/- 0.09 mmol x l(-1)) trials (mean +/- standard error). Similarly, the 6 h total area under the plasma TAG concentration versus time curve did not differ significantly between the control (9.84 +/- 1.40 mmol l(-1) x 6 h(-1)) and exercise (9.38 +/- 1.12 mmol x l(-1) x 6 h(-1)) trials. These findings suggest that a single session of resistance exercise does not reduce postprandial lipaemia.  相似文献

The longitudinal study described in this report investigated the effects of postsecondary public and proprietary school vocational training on students' subsequent job success in the United States. The study surveyed dropouts and graduates from public and proprietary schools in six vocational programs in four major cities, and compared their personal characteristics, job placement and earnings. Results showed that, compared with graduates, dropouts were more frequently males who were black, older, of lower socioeconomic status, and more likely from public programs. Also, few students who studied for upper status jobs (accountant, computer programmer, and electronic technician) got those jobs, regardless of whether they had graduated from or dropped out of their vocational programs. On the other hand, the majority of students who studied for lower-status jobs, in which women typically predominate, (secretary, dental assistant and cosmetologist) successfully found those jobs. Further, graduates fared significantly better in job placement than dropouts. Finally, persistence in, and graduation from a program (persistence and graduation) were unrelated to students' first earnings. However, students in lower-status occupations had higher later earnings if they completed their programs. These results suggest that vocational training, which may be done more efficiently in proprietary than public schools, enhances placement and later earnings only in lower-status jobs.  相似文献

Flexible, self-organised work groups will become increasingly important in rich countries like the U.S. as employment in the formal economic system continues to decline. Educational models and methods based on the linking of learning with productive work developed in Third World countries can give a valuable stimulus to educational innovation in those industrialized countries hardest hit by the current crisis.Education with production will be important in equipping people for the new situation. The article discusses examples of several types of education with production. Among issues raised are: what skills are needed; what sorts of people the different types of post-school education with production cater for; how to extend the benefits of self-organised work; some important factors in introducing education with production at school level, including demands on the teacher and relevance to pupils' needs. The role of the Foundation for Education with Production is briefly described.  相似文献

Currently, there is a lack of appropriate skill assessments available for use in golf. The aim of this study was to examine the discriminative validity and the test-retest reliability of the newly developed "Nine-Ball Skills Test". Participants of two ability levels (elite, n = 14; high-level amateur, n = 16) each hit nine golf shots of differing combinations of trajectory (straight, fade, draw) and height (normal, high, low) at an individually determined target area. Each shot was scored on its percent error index from the target and whether it achieved the maximum height as required. Participants completed the test twice using a 5-iron club. The elite group scored significantly higher (P < 0.05) than the amateur group for both the first and second rounds of the test as well as the combined scores. The between-round test-retest reliability was deemed to be not acceptable, thus we propose that the test's protocol should include use of the two rounds as standard. Due to the importance of ball striking and flight control to performance in golf, the Nine-Ball Skills Test is appropriate for providing a measure of this skill component in elite and high-level amateur golfers.  相似文献

The innovation value chain (IVC) divides the innovation process into three separate links or activities: knowledge gathering, knowledge transformation and knowledge exploitation. Here, we report a comparative panel data analysis of the IVC in Ireland and Switzerland. Both economies are small, very open and depend significantly on innovation to maintain competitive advantage. In recent years, however, R&D and innovation growth in Ireland has been markedly stronger than that in Switzerland. We investigate these differences through the ‘lens’ of the IVC. Significant similarities exist between some aspects of firms’ innovation behaviour in each country: strong complementarities emerge between external knowledge sources and between firms’ internal and external knowledge. And, in both countries, in-house R&D and links to customers prove important drivers of innovation. Innovation drives productivity growth in different ways in the two countries, however, through product change in Switzerland and through process change in Ireland. Other differences in the determinants of innovation performance linked to ownership and firms’ institutional context emphasise the systemic nature of innovation and the legacy of past patterns of industrial development.  相似文献

This paper examines hearing aid use by 60 congenitally deaf individuals who attended special education units in South Australia. The study indicates that only one-third to half of deaf adults wore their hearing aids in social situations for speech detection. Just over one-third (n = 22) of the deaf adults involved in this study wore their hearing aids at work and less than half (n = 27) wore their hearing aids at home. Younger deaf adults were more likely to wear their hearing aids in the home than older deaf adults. Younger deaf adults tended to wear their hearing aids more frequently when they were at school if they had perceived their teachers had a positive attitude to deafness. This study found that there was no statistically significant relationship between wearing hearing aids and employment status. There was also no statistically significant difference in hearing aid use between men and women. The low use of hearing aids could be attributed at least in part to the current Australian policy regarding supply and servicing of hearing aids to congenitally deaf individuals which ceases to be free after the individual reaches 21 years of age.  相似文献
