引文环境下对《科学学与科学技术管理》的科学计量分析 总被引:3,自引:0,他引:3
利用CSSCI(1998-2004)排除著者自引后的数据,从期刊被引的规模——频次、学术影响力、被引半衰期等角度对《科学学与科学技术管理》进行引文计量分析。得出,期刊影响力日益扩大,被引半衰期约3.5年,有一批高频被引著者和高频被引论文。 相似文献

Communities with high levels of social capital are likely to have a higher quality of life than communities with low social capital. This is due to the greater ability of such communities to organize and mobilize effectively for collective action because they have high levels of social trust, dense social networks, and well-established norms of mutuality (the major features of social capital). Communities with “bridging” social capital (weak ties across groups) as well as “bonding” social capital (strong ties within groups) are the most effective in organizing for collective action. People who belong to multiple groups act as bridging ties. When people with bridging ties use communication media, such as the Internet, they enhance their capability to educate community members and to organize, as needed, for collective action. This article summarizes evidence from stratified household survey data in Blacksburg, VA, showing that people with weak (bridging) ties across groups have higher levels of community involvement, civic interest, and collective efficacy than people without bridging ties among groups. Moreover, heavy Internet users with bridging ties have higher social engagement, use the Internet for social purposes, and have been attending more local meetings and events since going online than heavy Internet users with no bridging ties. These findings may suggest that the Internet—in the hands of bridging individuals-is a tool for enhancing social relations and information exchange, and for increasing face-to-face interaction, all of which help to build both bonding and bridging social capital in communities. 相似文献

INTRODUCTION Dynamic buckling of structures under impactloading has become a research hotspot and hasreceived increasing attention in the last decade fromdesigners of modern engineering structures. Mostpast investigations focused on simple structuressuch as columns, plates and cylindrical shells; pa-pers dealing with stiffened plate structures withwide application in engineering are limited. Zizicas (1952) investigated the dynamic buckl-ing of thin elastic plates. A theoretical solution f… 相似文献

AbstractIn this paper, we consider the intensifying pressures on critical research and academic integrity in a research policy context that has come to be increasingly dominated by an instrumentalist mind-set. Using sensitising resources drawn from Geoff Whitty’s critique of the ‘what works’ agenda, we reflect on the current conditions of academic labour and some of the key issues and dilemmas they pose for critical researchers in the sociology of education and beyond. In particular, we underline the trend for ‘what works’ agendas to become constitutive of academic identities and practices, including at micro-levels, such that the option of ‘standing outside’ them is shifting from being merely personally taxing to being institutionally disallowed. In addition to highlighting the dilemmas this creates for critical researchers and the threat this poses to expansive and democratic approaches to education, the paper emphasises the centrality of relationship-forming in understanding and underpinning academic integrity. 相似文献

迭代影响是媒体在技术升级和跨界融合发展中所呈现的一种非线性、浸润式和潜移默化的影响方式。媒体融合发展对大学校园文化的迭代影响主要表现为“客户”意识、“微”处着手和以“快”制胜等特征。面对媒体融合的迭代影响,亟须从话语引领、学生思维、内容创新、平台整合和媒介教育等层面加强大学校园文化建设,以积极有效的行动实现自身文化自觉。 相似文献

张謇师从张裕钊学习古文法始,张裕钊的学识、人品给张謇留下深刻的印象.他的淡薄功名利禄、爱国之心,对张謇的思想形成影响极深,为张謇的务实、进取奠定了思想基础;张謇的"父教育母实业"思想发扬了恩师的"讲求时务"的教育思想;张裕钊勤练书法的精神为张謇所学习,尤其是楷书上的指点,使张謇的书法终成大气. 相似文献
