[目的/意义]领域知识的跨学科交叉研究能够打破学科间的壁垒,有助于发现重大科学问题的解决方案。[研究设计/方法]基于图书情报学领域文献题录信息构建轻量级领域知识图谱,从中提取学科信息、国家信息、时间信息及其关联,采用时间与空间相结合的多维度分析方法,对学科交叉的演化进程以及国家差异进行跟踪与分析。[结论/发现]图书情报学领域内学科交叉现象日渐显著,各国家的学科交叉程度与倾向存在差异,一些目前尚不突出的交叉学科方向值得关注。[创新/价值]采用多维度视角分析学科交叉现象,相关结论可以为国家科技战略制定及学科发展规划提供有益参考。 相似文献

Direct and indirect measures were used to compare the written language abilities of three groups of college students: two with learning disabilities and one without learning disabilities. Main effects were found for group, but not gender. Differences between nonlearning disabled students (NLD) and those with learning disabilities (LD) in writing were evident on both types of measures. Performance by LD students with disabilities in an area other than writing differed depending on the type of measure and often was no different from either of the other two groups. The combined use of direct and indirect measures appeared most effective for examining the complexities of writing produced by all groups. 相似文献

Many studies demonstrate differences in the coverage of citing publications in Google Scholar (GS) and Web of Science (WoS). Here, we examine to what extent citation data from the two databases reflect the scholarly impact of women and men differently. Our conjecture is that WoS carries an indirect gender bias in its selection criteria for citation sources that GS avoids due to criteria that are more inclusive. Using a sample of 1250 U.S. researchers in Sociology, Political Science, Economics, Cardiology and Chemistry, we examine gender differences in the average citation coverage of the two databases. We also calculate database-specific h-indices for all authors in the sample. In repeated simulations of hiring scenarios, we use these indices to examine whether women's appointment rates increase if hiring decisions rely on data from GS in lieu of WoS. We find no systematic gender differences in the citation coverage of the two databases. Further, our results indicate marginal to non-existing effects of database selection on women's success-rates in the simulations. In line with the existing literature, we find the citation coverage in WoS to be largest in Cardiology and Chemistry and smallest in Political Science and Sociology. The concordance between author-based h-indices measured by GS and WoS is largest for Chemistry followed by Cardiology, Political Science, Sociology and Economics. 相似文献

“十七年”电影中的性别话语作为一种文化话语是一种功能、运动和关系,其意义也在这些功能、运动和关系中产生、发展和变化,英雄叙事功能本身就构成一个复杂的话语系统。因此,“十七年”电影英雄叙事的性别话语研究就必须结合其他话语系统如意识形态、历史等,才能充分考虑背后的权力关系,即叙事运作的策略性关系。 相似文献

AbstractBy applying feminist geographical theories and qualitative research methods, this article reveals Chinese women’s exercise experiences in urban spaces and discusses how women, through physical activity in neighbourhoods, public places and commercial facilities, constructed social spaces of their own. The findings show that exercise spaces are potentially sites for women’s health, well-being, social networking and collective empowerment. They challenge traditional gendered urban spaces by deconstructing the dual structure of ‘public’ and ‘private’ spheres, inducing women to gradually shift from the ‘edge’ to the ‘centre’. Though the spatial differences in women’s physical activities reflect the diversity and dynamics of women’s spatialities, they also imply the continuous social powers on women in exercise fields, where gendered disparities and class stratification may be sustained. 相似文献

Analyzing university faculty and graduate students data for ten of the top U.S. economics departments between 1987 and 2007, we find persistent differences in the gender compositions of both faculty and graduate students across departments. There is a positive correlation between the share of female faculty and the share of women in the PhD class graduating six years later. Using instrumental variable analysis, we find robust evidence that this relation is causal. These results contribute to our understanding of the persistent under-representation of women in economics, as well as for the persistent segregation of women in the labor force. 相似文献

This interpretive study sought to critically examine young people's subjective meanings and experiences related to parent volunteerism in community youth sport. Using a constant comparative method of data analysis, the perspectives of 19 participants from 7 different family units (9 sons and 10 daughters) in Ontario, Canada were examined. The findings call attention to the gendered importance of fathers in highly visible volunteer roles (e.g., coach, game announcer) and the lack of recognition or appreciation for mothers’ formal volunteer roles (e.g., assistant coach, league's board of directors) as well as informal volunteer roles (e.g., fundraiser). Moments of conflict in relation to peer groups as well as siblings and the potential for volunteerism to enhance a sense of connection through moments of togetherness and skill development are also emphasized. 相似文献

This paper explores the physical education (PE) and physical activity experiences of a group of South Asian, Muslim girls, a group typically marginalised in PE and physical activity research. The study responds to ongoing calls for research to explore across different spaces in young people's lives. Specifically, I draw on a ‘middle-ground’ approach, using Hill Collins' matrix of domination and the notion of intersectionality. These concepts offer the possibility to explore the kinds of settings (physical, social and cultural) in which girls undertake PE and physical activity, how these spaces influence experience and how the girls navigate these spaces. The study is based in a large, urban, co-educational, secondary school in Yorkshire, England (95% of the students are from minority ethnic communities, 91% are Muslim and 63% live in the top 10% most deprived neighbourhoods in the country). Data generation involved three phases: observations, creating research artefacts in focus groups and in-depth interviews. The findings reveal the diverse ways the girls are physically active. They also demonstrate a complexity to their involvement which is contingent upon space, discourses and people. For example, discourses of competition, ability and peers are more significant within PE; whilst family, religion and culture feature beyond this context. The paper concludes by acknowledging the girls' heterogeneity and agency in the ways they strategically navigate spaces in their quest to be physically active on their terms. 相似文献
