In a joint project involving European association staff and sports scientists, basic structural data were collected on British, Swedish, Spanish and German athletics clubs to be used for analysis of hypotheses concerning conditions of participation in sports clubs, particularly by children and adolescents. The results showed clear differences in organizational level as well as membership and activity structures in comparisons between European countries and within Germany. The findings revealed the differential functions and significance of sports clubs in the context of the respective institutions and cultures.  相似文献

Research on teaching in Physical Education (RT-PE) comprises a great deal of complex phenomena. These can be understood at a more profound level by using mixed methods research approaches (MMR). Hence, the aim of this paper is to analyze potentials and limitations of mixed methods research in RT-PE, also trying to generate an additional value for MMR.  相似文献

This paper exploits discontinuities and randomness in the college admissions in Sweden in 1982, to estimate the economic return to college in the 1990s. At the time, college admissions were highly selective and applicants were ranked with respect to their formal merits. Admissions were given to those ranked higher than some threshold value. At the margin, applicants were sometimes randomly assigned to college. Exploiting this Regression-Discontinuity design, individuals who were admitted in 1982 are estimated to have about 0.20 years longer college education in 1996. However, the earnings effects for applicants at the margin of admission are insignificant. Controlling for the college admission determinants, the OLS-estimates of the return to college is 1.4 percent in 1991–96. The IV-estimates are not significantly different from the OLS counterparts.  相似文献

Environmental education usually appeals to the students’ knowledge and rational understanding. Even though this is needed, there is a neglected aspect of learning ecologically fruitful action; that of the lived‐body. This paper introduces the lived‐body as an important site for learning ecological action. An argument is made for the need of a biophilia revolution, in which refined experience of the body and enhanced capabilities for sensing are seen as important ways of complementing the more common, knowledge‐based environmental education. Alienation from the physical environment is seen as one key element in producing environmental devastation. Consequently, human alienation from nature is seen as closely related to alienation from one's body. It is claimed that through overcoming the (Cartesian) dualist alienation of human consciousness from its lived body, we can decrease the alienation of human beings from their environment. Methods of contemplative pedagogy are introduced for addressing alienation. By getting in touch with the tangible lived‐body in yoga or mindfulness meditation we reconnect to the material world of nature. Contemplative pedagogy cultivates the body and its senses for learning intrinsic valuation and caring for the environment. Lived‐body experience is challenging to conceptualise; we use Maurice Merleau‐Ponty's concept of the flesh in our attempt to do so. Finally, this paper suggests some contemplative practices of the lived‐body for environmental education. Experiencing the flesh of oneself and the world as one and the same is an environmentally conducive experience that gives value and meaning to the flourishing of all life, human and non‐human.  相似文献

Psychological factors behind incidental information acquisition   总被引:1,自引:0,他引:1  
This paper discusses incidental information acquisition in the light of psychological aspects. A theoretical introduction is followed by an account of three research projects where incidental information acquisition was related to personality traits, approaches to studying, and emotions. The respondents were grades 6–12, master's thesis, and mature library and information science (LIS) students representing an age range of 12–53 years. An energetic personality, high motivation, and positive emotionality were shown to enhance likelihood for incidental acquisition, while low motivation, stress, and insecurity reduced receptivity.  相似文献

The effects of query structures and query expansion (QE) on retrieval performance were tested with a best match retrieval system (InQuery1). Query structure means the use of operators to express the relations between search keys. Six different structures were tested, representing strong structures (e.g., queries with facets or concepts identified) and weak structures (no concepts identified, a query is a bag of search keys). QE was based on concepts, which were first selected from a searching thesaurus, and then expanded by semantic relationships given in the thesaurus. The expansion levels were (a) no expansion, (b) a synonym expansion, (c) a narrower concept expansion, (d) an associative concept expansion, and (e) a cumulative expansion of all other expansions. With weak structures and Boolean structured queries, QE was not very effective. The best performance was achieved with a combination of a facet structure, where search keys within a facet were treated as instances of one search key (the SYN operator), and the largest expansion.  相似文献
