Abstract The purpose of this study was to determine if factor patterns of selected sports skills were similar for two samples, a skilled sample and one consisting of a wide range of skills. Comparisons were also made with kinesiological evidence regarding the patterning of basic sports skills. Data consisting of performance scores on various sports skills were available for 166 high school girls. Out of this sample, a smaller sample was drawn consisting of 69 girls who were above average in skill. Two factor models, alpha and incomplete image analysis, were used in the analysis of this data. The factor pattern of selected sports skills performed by subjects above average in skill was similar in many respects to that of a sample which included a wide range of skill. The primary difference lay in the clustering of overarm skills which appeared in the above-average factor pattern. The overarm and push patterns of the above-average sample resembled the patterns of skill obtained through kinesiological analysis. The structure of kicking, underarm, and sidearm skills remained obscure, based on the results of factor analytic techniques. 相似文献

Abstract The aim of this study was to determine whether rates of total fat and carbohydrate oxidation and endurance capacity during running conducted in the fasted state are influenced by the glycaemic index (GI) of high carbohydrate diets consumed over 5 days. Nine healthy males performed three treadmill runs to exhaustion at 65% of maximum oxygen uptake ([Vdot]O2max): after a habitual diet (control trial), after 5 days on a high carbohydrate/high glycaemic index diet, and after 5 days on a high carbohydrate/low glycaemic index diet in randomized counterbalanced order. No significant differences in rates of fat and carbohydrate oxidation, concentrations of plasma insulin, glucose, non-esterified fatty acids and glycerol, or time to exhaustion were observed between the high carbohydrate/high glycaemic index and high carbohydrate/low glycaemic index trials. Compared with the control trial, the concentration of plasma glycerol and rate of fat oxidation were lower (P < 0.05) and the rate of carbohydrate oxidation higher (P < 0.05) in both the high carbohydrate/high glycaemic index diet and high carbohydrate/low glycaemic index trials during the run to exhaustion. In conclusion, the extent by which a high carbohydrate diet consumed over 5 days reduces rate of fat oxidation during subsequent running exercise in the fasted state is not influenced by the glycaemic index of the diet. 相似文献

In this work, we elaborate on the meaning of metadata quality by surveying efforts and experiences matured in the digital library domain. In particular, an overview of the frameworks developed to characterize such a multi-faceted concept is presented. Moreover, the most common quality-related problems affecting metadata both during the creation and the aggregation phase are discussed together with the approaches, technologies and tools developed to mitigate them. This survey on digital library developments is expected to contribute to the ongoing discussion on data and metadata quality occurring in the emerging yet more general framework of data infrastructures. 相似文献

In this article we consider the development of key policy issues in England, related to the area of literacy learning and children who are considered to have difficulties in literacy in their early years. We trace the tensions which have arisen since the 1980s between different policies and practices in these areas. These tensions include pressures to raise standards of literacy and to support children with difficulties, and the establishment of a prescribed curriculum for young children. In particular, we focus on the blend and clash of national educational policy ideals in areas related to literacy and children who have been categorised as having ‘special educational needs’, and how these have influenced the development of the Early Literacy Support Programme (ELS) (DfES, 2001a; 2001b). This is a programme set up by the Department for Education and Science in England for children in Year 1, aged 5 to 6 years old. 相似文献

This study examines the relationship between Singaporean college students'attitude toward Americans and their exposure to U.S. exported entertainment media. The 328 Singaporean college student participants expressed relatively neutral attitudes toward Americans and reported high consumption of U.S. entertainment media (movies, television shows, magazines, music). Exposure to American media was found to correlate positively with student attitudes toward Americans. In contrast to some media critics' contention that exposure to U.S. media fosters negative attitudes among citizens of other countries, this study suggests that U.S. entertainment may influence attitude toward Americans in a positive direction. 相似文献
