Social support and recovery from sport injury: elite skiers share their experiences.

Research suggests that social support can be an important coping resource for athletes recovering from sport injury. Few studies have investigated this claim, however. To address this gap in the literature, 10 elite downhill skiers who had recovered from serious sport injuries were interviewed about the sources of stress associated with injury and the role of social support in recovery from sport injury. This paper presents the social supportfindings that emergedfrom this research'. Content analyses of the social support data revealed that the skiers needed various types of emotional, informational, and tangible support from the occurrence of injury through the return to full activity. Members of the treatment team, the ski team, and the skiers' home support net works provided social support throughout these phases. In general, the skiers were satisfied with the support received, indicating that it reduced distress and kept them motivated throughout recovery. The findings from this research have implications for the design of sport injury interventions.     

Acculturation orientations of competing host communities toward valued and devalued immigrants

This study explored how members of competing host communities may endorse different acculturation orientations towards valued and devalued immigrants settled in the bilingual city of Montreal. Francophone (N=422) and Anglophone (N=401) host community students from low-, medium- and high-ethnic diversity colleges completed the host community acculturation scale (HCAS) along with a questionnaire monitoring a range of social psychological correlates of acculturation orientations. Results showed that Anglophones were more integrationist and individualist and less assimilationist than Francophones. Both Francophones and Anglophones were more integrationist and individualist and less assimilationist, segregationist and exclusionist toward valued than devalued immigrants. Attending a multiethnic college had no influence on respondents’ acculturation orientations. The more welcoming acculturation orientations of Anglophones compared to Francophones was corroborated by results obtained with immigrants attending the French and the English colleges. Social psychological profiles of the respective acculturation orientations were similar across both host communities thus supporting the construct validity of the HCAS. Attitude toward co-national outgroup was a significant determinant of each acculturation orientations, suggesting that intergroup relations between rival host communities has an impact on acculturation orientations toward immigrants.     

穴位离子导入对皮艇运动员心肺功能的影响

采用RPE评分、运动成绩测试、心肺功能测试及心脏内分泌激素放射免疫法检测等方法对运动员心脏功能进行跟踪观察。结果表明：(1)穴位离子导入能明显改善运动员的主观感觉，提高专项成绩，改善心肺功能，降低无氧闲心率，提高有氧耐力，推迟心源性运动性疲劳的发生；(2)穴位离子导入可改善运动员心脏神经肽ET和CGRP的分泌，使之向更有利于适应运动负荷的方向发展。结论是：(1)心源性运动性疲劳的发生与多因素相关；(2)穴位离子导入能多环节、多层面地保护心肌和改善心脏功能，从而延缓疲劳产生和促进疲劳消除。

Alternative technologies and social studies textbooks

In order to determine the potential of alternative technologies in social studies education, we must understand the goals of such education, the capabilities of the technologies, and teachers’ and students’ responses to new technologies. The author suggests that the new technologies can contribute to the goals of learning about the past, learning about democratic life and institutions, and making students knowledgeable as consumers and producers of information. One major obstacle is a lack of time and money for teachers to experiment with the technologies. Stephen T. Kerr is professor of education in the College of Education at the University of Washington. His research focuses on the application of new technologies in schools and other educational environments, and particularly on the ways in which technology affects the social structure (roles and expectations, instructional patterns, organization) of those institutions. He has done work on human-computer interaction, as well as on how new communication technologies have changed the educational system of the former USSR.

中国北方汉族青年ACE 基因I/ D多态性频率分布特征

通过分析与探讨汉族普通人群ACE基因I／D多态频率分布特征，试图为中国优秀耐力运动员的基因选材研究提供中国人相关人群ACE基因I／D多态频率分布的基础数据。选择18-22岁汉族学生216名作为研究对象，观察其ACE基因I／D多态频率分布。结果显示：北方汉族青年的ACE基因I／D多态频率分布，与国内相关研究结果一致，与欧美人群有非常显著差异。研究认为：从种族单一性、样本数量和年龄段的选择等因素考虑．研究结果不仅可以作为北方汉族青年ACE基因I／D多态频率分布的代表，而且对于杰出耐力的多态性标记研究来讲是理想的对照群体。
