Verbal intelligence, English-language skills, personality, and attitude scales were used as predictors of academic performance in 230 male and female arts students at the University of Hong Kong. A series of bivariate, multiple, and canonical correlation analyses were performed. The results showed that verbal intelligence and attitudes, excepting study orientation, were not predictive of performance. English-language skills had the most predictive value, accounting for about 10% of the variance of performance measures. Personality variables failed to predict performance when composite criterion measures (GPAs) were used; however, they proved to be of predictive value when results of individual academic subjects were used as criterion measures. The study points to the importance of using noncomposite criterion measures in prediction and of considering the cultural context of achievement. 相似文献

This study explores the content validity of a profile used to describe the communication behaviour of people with intellectual disabilities. The profile, named Biala-II - a Wiradjuri (an Australian Aboriginal language) word for "I understand you" - makes use of the knowledge of informants who are able to provide specific and detailed information on the ways in which a person communicates. This information can be used by ''communication partners'' to guide their interactions with a person whom they do not know well. Five samples of experts - parents, researchers, residential workers, speech pathologists, and special education teachers - rated 16 "best practice" indicators and then rated Biala-II in relation to these indicators. They also answered questions about specific features of the profile with attention to the methodology employed and the likelihood that its use would improve communication with people with an intellectual disability. The results reveal a high level of support for the profile. 相似文献

Chinese students at an English-Language university: Prediction of academic performance 总被引：1，自引：0，他引：1
There is a paucity of systematic research on prediction of success at the tertiary education level for Asian students, despite the important role that universities play in Asian communities, and despite the increasing numbers of such students who are coming to the West to study. This study reviews evidence collected over the past ten to fifteen years, which relates to the issue of prediction of academic performance of Chinese students at an English-Language and Western-oriented university - the University of Hong Kong. This review is complemented by an analysis of data collected longitudinally over a five year period, using multiple regression, multiple correlation, path analysis and canonical correlation analyses. The results provide evidence of factors which are important in determining the ability of a student to adapt to the foreign cultural and language barriers that exist at this university. In particular, ability in English language and mathematics provides good and reasonably independent predictors of success. The data show the importance of considering the cultural background of students when assessing their aptitude for study, and offer information for Western universities regarding their admissions procedures for Chinese students. 相似文献

Graded exercise tests are commonly used to assess peak physiological capacities of athletes. However, unlike time trials, these tests do not provide performance information. The aim of this study was to examine the peak physiological responses of female outrigger canoeists to a 1000-m ergometer time trial and compare the time-trial performance to two graded exercise tests performed at increments of 7.5 W each minute and 15 W each two minutes respectively. 17 trained female outrigger canoeists completed the time trial on an outrigger canoe ergometer with heart rate (HR), stroke rate, power output, and oxygen consumption (VO2) determined every 15 s. The mean (+/- s) time-trial time was 359 +/- 33 s, with a mean power output of 65 +/- 16 W and mean stroke rate of 56 +/- 4 strokes min(-1). Mean values for peak VO2, peak heart rate, and mean heart rate were 3.17 +/- 0.67 litres min(-1), 177 +/- 11 beats min(-1), and 164 +/- 12 beats min(-1) respectively. Compared with the graded exercise tests, the time-trial elicited similar values for peak heart rate, peak power output, peak blood lactate concentration, and peak VO2. As a time trial is sport-specific and can simultaneously quantify sprint performance and peak physiological responses in outrigger canoeing, it is suggested that a time trial be used by coaches for crew selection as it doubles as a reliable performance measure and a protocol for monitoring peak aerobic capacity of female outrigger canoeists. 相似文献

High skills are today seen as being of vital importance to economies, industries, companies and individuals. The engineering industry is no exception and the graduate engineer has a key position in this regard. In the research reported in this paper, the authors use in-depth interviews with industry experts to investigate the provision of undergraduate engineering education in the UK. The current and future skill needs of industry are examined. A typology of future engineering roles and their requisite attributes is proposed. Implications for undergraduate engineering are also discussed. 相似文献

Abstract The aim of this study was to establish a graded exercise test protocol for determining the peak physiological responses of female outrigger canoeists. Seventeen trained female outrigger canoeists completed two outrigger ergometer graded exercise test protocols in random order: (1) 25 W power output for 2 min increasing by 7.5 W every minute until exhaustion; and (2) 25 W power output for 2 min increasing by 15 W every 2 min to exhaustion. Heart rate and power output were recorded every 15 s. Expired air was collected continuously and sampled for analysis at 15-s intervals, while blood lactate concentration was measured immediately after and 3, 5, and 7 min after exercise. The peak physiological and performance variables examined included peak oxygen uptake ([Vdot]O2peak), minute ventilation, tidal volume, ventilatory thresholds 1 and 2, respiratory rate, respiratory exchange ratio, heart rate, blood lactate concentration, power output, performance time, and time to [Vdot]O2peak. There were no significant differences in peak physiological responses, ventilatory thresholds or performance variables between the two graded exercise test protocols. Despite no significant differences between protocols, due to the large limits of agreement evident between protocols for the peak physiological responses, it is recommended that the same protocol be used for all comparison testing to minimize intra-individual variability of results. 相似文献

Abstract This study examined the effect of shoulder angle and gender on physiological and perceptual responses during incremental peak arm ergometry. Healthy adults (nine males, seven females) volunteered for the study and completed an incremental arm ergometry test on two separate occasions at two different shoulder angles (90° and 45°). Initial work rate was set at 16 W · min?1 and was increased progressively until exhaustion. Cardiorespiratory and perceptual responses were recorded at the end of each minute and compared using separate three-way (position × work rate × gender) repeated-measures analyses of variance. The systematic bias of peak responses was examined using separate two-way (position × gender) analyses of variance, while reproducibility of these parameters was explored using intraclass correlation coefficients, measurement bias/ratio, and 95% ratio limits of agreement. Despite a significantly greater peak heart rate for the 45° position, cardiorespiratory and perceptual responses were similar at peak exercise for both positions. Peak values for all variables, although similar, demonstrated similar and large inter-test variability for men and women. Reduction of the shoulder joint angle to 45° did not enhance peak work rate and peak oxygen consumption during seated upper body exercise. Due to the large inter-test variability, arm ergometry should be conducted using the same seated position. 相似文献
