ISI数据库——学术期刊及网站的选择

ISI（美国科学信息研究所）的基本任务是向其用户提供所需要的世界最重要、最有影响的期刊收录信息,ISI数据库不仅可以检索当年而且可追溯以往。现有数据库收录自然科学、社会科学、艺术与人文科学的国际期刊8500余种。ISI能完整地检索它所收录的任何一条文献数据。期刊的评估与选择是动态过程,每年ISI数据库的来源期刊都会有所增加或删减。每种期刊在被录用或被淘汰前都经过内容广泛的评估过程。ISI数据库期刊评估要考虑多种因素,评估范围从质到量标准不同,包括基本出版标准、学术内容、作者的国际化程度,及其与之相关的引文     

Identification with sport teams as a function of the search for certainty

Based on ideas from subjective uncertainty reduction theory, we examined the extent to which individuals hold similar sport team preferences to their family and friends. We also assessed the extent to which perceived sport importance and personal need for structure are influential in the development of team identification. Australian high school students aged 15.5+/-1.0 years (mean+/-s) completed questionnaires containing the Personal Need for Structure Scale, the Relational-Interdependent Self-Construal scale, a Team Identification Scale, and items assessing perceptions of sport importance and team preferences. As expected, correlations indicated that preferences for sport teams were significantly related to the preferences of family and friends. Separate analyses of variance confirmed the remaining hypotheses. More specifically, individuals who perceived that sport was important identified with the team more than individuals who perceived sport to be less important. Also, individuals high in personal need for structure scored higher in cognitive/affective team identification than those low in this need. Individuals with differing needs for structure did not differ in their scores on other dimensions of team identification. The results support the notion that cognitive/emotional attachments to sport teams are influenced by perceptions of the importance of sport and by needs for subjective structure. It is possible that other psychological motives, such as the desire for self-esteem, facilitate the development of evaluative dimensions of team identification.
