In recent years, we have witnessed an upsurge in the attention given to Sport for Development and Peace (SDP). Yet, despite a burgeoning body of scholarship, SDP remains largely undertheorized. Emergent perspectives, however, point to the complex nature of SDP programmes. The purpose of this article is to assess how Sen’s Capability Approach – a normative framework rooted in human development – may help us better understand SDP at the conceptual level. In this paper, we analyse: (a) existing theories on SDP, (b) the Capability Approach and (c) implications of re-examining SDP through the Capability Approach. This includes an analysis of the applicability of the Capability Approach to SDP practice, policy and research. We conclude by suggesting that the Capability Approach provides a malleable normative framework that can promote conceptual clarity of SDP across a multitude of epistemological, theoretical and methodological perspectives. 相似文献

Physical fitness and muscular strength are important performance factors for Olympic class sailors, but the physical demands vary greatly between yacht classes, and limited information is available regarding the physical demands for the different crew positions. In the present paper, strength and aerobic capacity data from elite Olympic sailors are presented and compared with previous findings. Furthermore, a system for classification of Olympic class sailors is suggested. Peak aerobic capacity (peak oxygen uptake, VO(2peak)) and maximal isometric and isokinetic muscle strength of the knee extensors and flexors were assessed, together with the hamstring/quadriceps strength ratio (H/Q ratio). Peak aerobic capacity (ml O(2) . min(-1) . kg(-2/3)) was as follows: males - static hikers (n = 5) 215, s = 7; dynamic hikers (n = 8) 252, s = 17; trapezing helmsmen (n = 6) 234, s = 15; trapezing crew (n = 10) 239, s = 16; females - dynamic hikers (n = 6) 194, s = 16; trapezing crew (n = 2) 200, s = 13. Strength data for hikers, presented as peak moments (normalized to body weight) obtained during eccentric, isometric, and concentric contraction (Nm . kg(-1)) respectively were as follows: males - quadriceps: 3.66 (s = 0.68), 3.97 (s = 0.66), 1.82 (s = 0.34); hamstrings: 1.93 (s = 0.22), 1.38 (s = 0.41), 1.05 (s = 0.21); females - quadriceps: 3.84 (s = 0.71), 3.81 (s = 0.58), 1.60 (s = 0.28); hamstrings: 1.75 (s = 0.23), 1.10 (s = 0.16), 0.84 (s = 0.13). The peak moment based H/Q ratios for slow eccentric and concentric contractions were 0.42 (s = 0.11) and 0.39 (s = 0.04) for males and 0.43 (s = 0.06) and 0.39 (s = 0.04) for females respectively. Elite Olympic class sailors demonstrated high VO(2peak) values comparable to those observed in other non-endurance sports. The strength data revealed very high quadriceps strength for hikers, which is likely a result of the high muscle forces encountered during sailing, and a low H/Q ratio. To ensure optimal knee joint stabilization during sailing and other training activities, it is suggested that hikers should counter this strength imbalance by performing additional strength training for the hamstrings muscle group. 相似文献

The aim of this study was to examine changes in indirect markers of muscle damage during 3 weeks of stretch-shortening exercise with a progressively increasing load and continued modulation of various key training variables. Eight healthy untrained men performed a drop-jump programme involving a progressive increase in load impact with respect to the number of jumps performed, drop (platform) height, squat depth amplitude, and addition of weights. Maximal concentric and isometric knee extensor strength were assessed immediately before and 10?min after each training session. Voluntary and 100 Hz-stimulation-evoked torque decreased acutely after each training session relative to pre-exercise values (P?0.05) but recovered before the subsequent training session. Post-exercise plasma creatine kinase activity increased from 162.2?±?56.2 IU?·?l(-1) to 284.3?±?116.3 IU?·?l(-1) at 48?h after the first training session (P?0.05) and remained marginally elevated throughout the training period. The present results indicate that detrimental muscle damage can be avoided with drop-jump training even with the gradual introduction of more demanding exercise induced by increasing the volume, intensity, and muscle stretch amplitude. These findings suggest that the human neuromuscular system is highly adaptable to progressively varied loading demands during stretch-shortening exercise training. 相似文献

Educational leaders have a comprehensive responsibility for how preschools and schools work with children in need of special educational support. The aim of this research is to study how educational leaders (a) explain why children have problems in schools, (b) consider how preschools/schools should help children in need of special support and (c) the role they believe that Special Educational Needs Coordinators (SENCOs) should have in such work. Educational leaders (N = 45) working in preschools and regular compulsory schools in a Swedish municipality responded (100%) to a questionnaire. According to the results of this study, this group seems to view difficulties in schools as being caused primarily by individual shortcomings. Educational leaders often advocate solutions that are closely linked to the work of special educators. The educational leaders believe SENCOs should work with supervising staff and focus on documentation and evaluations. Preschool leaders attribute children's need of special support to teachers more often than their colleagues in compulsory schools. 相似文献

There is an ongoing discussion about what content that should be taught in science education and there are different views among teachers about what represent good science content. However, teachers are not isolated individuals making their own interpretations, but are part of institutionalised systems building on patterns in the selection of teaching goals and content. Earlier research shows that teachers teach in alignment with different selective traditions, which can be understood as well-developed teaching habits. Individual teachers seem to develop their personal habits on the basis of the contextual situations created by earlier generations of teachers. In order to find out which content teachers find representative for science education, we asked nine teachers to take part in group interviews to talk about what they value as “good” science content. The participants were grouped according to their selective traditions expressed in earlier studies. The method was used to dynamically explore, challenge and highlight teachers’ views. The starting point for the group discussions is national tests in science. In Sweden, national tests in biology, physics and chemistry were introduced in secondary school science (year 9) in 2009. One overarching aim of these tests is to support the implementation of the science curricula and to include for example knowledge about socio-scientific issues (SSI). The content of the tests can consequently be seen as important for teachers to consider. The findings show that ‘resistance’ to including SSI is not just an issue for individual teachers. As individuals teachers can create many kinds of obstacles, but still be interested in integrating SSI in their science teaching. However, in group discussions the teachers tend to collectively adopt the scientific rational discourse. This discourse is what joins them and creates their common identity as science teachers. In turn, they seek to free scientific knowledge from social knowledge and thereby make assessment easier. 相似文献

Alternative Pathways to Chronic Depressive Symptoms in Young Adults: Gender Differences in Developmental Trajectories 总被引:1,自引:0,他引:1

Personality and intelligence associated with depressive symptoms in 23-year-olds were evaluated using prospective data from preschool through adolescence. Gender moderated the prospective relations between personality/intelligence and age-23 depressive symptoms. Young men with elevated age-23 General Behavior Inventory (GBI) scores manifested as early as in preschool allocentric behaviors: undersocialization and interpersonal antagonism. This pattern remained highly stable over the following 15 years. Prospective correlates of depressive symptoms in young women—not reliably identified until adolescence—were more likely than in young men to express autocentric concerns: oversocialization and introspective concern with self. These gender differences continued to persist but decreased in strength after puberty. Intellectual competence displayed significantly stronger negative correlations with age-23 GBI scores in males than in females. Findings were discussed in terms of gender differences in the development of chronic depressive symptoms, with special emphasis on equifinality in developmental pathways. 相似文献

The physical demands and rally characteristics of elite-standard men’s squash have not been well documented since recent rule changes (scoring and tin height). This information is needed to design optimal training drills for physical conditioning provided here based on an analysis of movement and shot information. Matches at the 2010 (n = 14) and 2011 (n = 27) Rowe British Grand Prix were analysed. Rallies were split into four ball-in-play duration categories using the 25th (short), 75th (medium), 95th percentiles (long) and maximum values. Cohen’s d and chi-squared tests of independence evaluated effects of rally and rule changes on patterns of play. The proportion of long, middle and short shots was related to the duration of the rally with more shots played in the middle and front of the court in short rallies (phi = 0.12). The frequencies of shots played from different areas of the court have not changed after the adoption of new rules but there is less time available to return shots that reflect the attacking nature of match play for elite-standard men players. Aspiring and current elite-standard players need to condition themselves to improve their ability to cope with these demands using the ghosting patterns presented that mimic demands of modern match play. 相似文献

Mindfulness based stress reduction (MBSR) for academic evaluation anxiety and self-confidence in 70 help-seeking bachelor’s and master’s students was examined. A repeated measures analysis of covariance on the 46 students who completed pretreatment and posttreatment measures (median age = 24 years, 83% women) showed that evaluation anxiety and self-confidence improved. A growth curve analysis with all 70 original participants showed reductions in both cognitive and emotional components of evaluation anxiety, and that reduction continued postintervention. Although more research is needed, this study indicates that MBSR may reduce evaluation anxiety. 相似文献
