Previous intervention studies in school sports designed to test the socialisation hypothesis have tried to raise students’ self-concepts. However, this goal seems to be of questionable functionality: From both an educational and a psychological perspective, it would seem preferable to aim toward making self-concepts as realistic as possible. Underestimating self-concepts might impede performance-related behaviour, whereas overestimating might be dysfunctional, particularly in social interactions. This dichotomy is used to examine which manifestations of the self-concept physical education needs to promote from a psychological perspective. It creates a new perspective for future interventions designed to promote the self-concept in physical education. 相似文献

We investigate how outside directors on supervisory boards influence innovative activities of the firms they advise and monitor. Based on panel data on the largest German companies, the econometric analysis shows a positive influence of external executives on innovative firm performance, measured by patent applications. Differentiating between outside directors from innovative and non-innovative companies reveals that only outside directors from innovative firms increase patenting activities at the firms they advise and monitor. This effect increases with the technological proximity between the appointing firm and the outsider's home firm. Outside directors from non-innovative firms are negatively associated with the appointing firm's innovativeness. The results indicate that external executives with an appropriate professional background can provide valuable specific knowledge and expertise to the board. 相似文献
