In this study, we used the trans-contextual model of motivation (TCM) to examine the effect of Sport Education (SE) on students' participation in a voluntary lunch recess sport club. A total of 192 participants (ages 9-14 years) completed measures of the TCM constructs before and after a 12-week SE intervention period. Participants had the opportunity to participate in weekly, voluntary lunch recess sport club sessions during the intervention period. SE elicited a moderate increase in autonomous motives in physical education. The TCM accounted for a significant proportion of the explained variance in lunch recess sport club intention and participation. Autonomy-supportive curricular models, such as SE, may have the potential to facilitate transfer of motivation and participation in physical activity from a physical education to an extracurricular context. 相似文献

Abstract This study examined dissonance in physical activity (PA) between two youth-specific hip-derived intensity cut-points for the Actiwatch (AW), and compared PA between hip and wrist placements using site-specific cut-points. Twenty-four children aged 11.2?±?0.5 years wore the AW on the right hip and non-dominant wrist during a typical school day. Minutes of sedentary behaviour and vigorous activity were greater using Puyau et al. (2002) cut-points, but light, moderate, and moderate-to-vigorous (MVPA) were greater when derived using Puyau et al. (2004) cut-points (P?相似文献

The causes of the transfer of technology between countries is now seen as an important dimension of the diffusion of new products and processes. Despite its obvious importance, there has been little empirical research investigating the international transfer of technology, although the work of Schiffel and Kitti (Research Policy 7 (1978)) provides a useful foundation on which to build. The research reported below tests the hypothesis that the transfer of technology between countries, as measured by the movement of patented invention, is influenced by both supply side and demand side factors. The principal variables are: patenting activity in the country of origin; the size of the recepient economy; international trade in goods and services; and the operations of multinational producing enterprises. These vaiables explain most of the variation across countries in the transfer of U.S. technology abroad. The worldwide distribution of U.S. based multinational enterprises appear to play an important part in explaining U.S. technology tranfer. On the other hand, the remaining international differences in patent law do not seem to significantly affect patent flows between countries. 相似文献
