期刊论文被引用及其Web全文下载的文献计量分析   总被引:31,自引:0,他引:31  
运用《中国学术期刊综合引证报告》及《中国学术期刊全文数据库Web下载统计报告》的文献计量数据分析了期刊论文网上下载频次的年代分布和被引用频次的年代分布,对比了它们的峰值(百分数)和峰值与统计年的年限差,得到“去年发表的论文被下载多,前年发表的论文被引用多,当年发表的论文下载频次与被引频次的比值高”这一规律性认识。研究了文献的网上下载频次分布和被引用频次的分布,对比了它们的集中系数。鉴于文献网上下载指标的排序与被引用指标的排序并不完全一致,建议将它们都作为独立指标在综合评价中予以适当考虑。  相似文献

网站规模是决定网站信息资源丰裕度和用户信息检索效率的重要因素,网站的字节数、总文件数、页面文件数和总链接数是目前用于衡量网站规模最重要的指标。本研究以美国101所著名商学院和医学院的网站,以及国内7所知名财经院校的网站为研究对象,通过对中、美网站以及美国商学院与医学院网站的比较分析,不仅明确了中、美网站在规模上的差异,更重要的是为大学网站建设和评价提出了具有重要价值的参考数据。  相似文献

This article explores how the library-student liaison program at Eastern Washington University (EWU) Libraries has evolved into an opportunity for students to develop leadership skills. Originally designed to foster better communication between the EWU Libraries and students enrolled at the university, we recognized that the process of achieving established goals for the program provided a vehicle for students' leadership-skill development. To facilitate the leadership process, librarians employed the Social Change Model. Designed specifically for college students, this model engages the student to develop individual capacities to strengthen group activities that foster positive changes in the community and society.  相似文献

从文件生命周期理论到文件连续体理论,档案界对文件运动形式的理解从线性向多维转变。在后现代主义档案观的影响和跨界合作的时代背景下,四维的文件连续体理论模型逐渐向五维演变。本文以加拿大档案学者勒梅教授及其团队提出的“第五维度理论”为基础,认为应该充分考虑利用者在档案工作流程中的作用,同时将对档案的“探索”性开发看成是对文件连续体理论模型的第五个维度。  相似文献

Student teachers are expected to develop their teaching skills sooner and more rapidly. However, a sound evaluation instrument that can be used to diagnose and monitor the skilfulness level to aid formative assessment of student teachers is still limited. This article is aimed to calibrate and validate a teaching skill evaluation instrument for use in secondary education. A total of 264 student teachers in the Netherlands participated in the study. Rasch and multilevel analyses were used. Results suggest that the evaluation instrument meets the restrictive assumptions of the Rasch model and has predictive value for academic engagement. This adds validation evidence and justifies the calibration of the evaluation instrument to be used for monitoring the development of teacher's teaching skills.  相似文献

In recent years, web sites where individual consumers can rate and review goods and services have mushroomed all over the Internet. Restaurants are particularly affected by online reviewing. If the impact of online consumer reviews (OCRs) on the demand side of markets is now well understood and measured, few studies examine the reception of this new evaluation method by those who are assessed. Based on interviews with French restaurant managers, our research shows that OCRs systems reconfigure relations of accountability in the restaurant industry. We use the notion of reactivity to describe the mechanisms through which the new evaluation system transforms the activity of restaurants. We also examine the affects surrounding the reception of ratings and reviews by restaurant managers and the moral criteria that accompany their discourses on online reviews. Many restaurants consider online reviews as a brutal and hypocritical mode of judgment. The judgment produced by online ratings and reviews is not easily borne by restaurant managers, because it challenges the conventions of quality they had previously internalized as legitimate, that is, those produced by professional experts. We interpret this ambivalent reception as the unfinished movement of transforming a performative reputation device into a legitimate evaluation institution.  相似文献

Bringing evidence-based treatments to community practice is a critical challenge for the field. When implemented in the community, evidence-based treatments often fail to provide the benefits shown in laboratory settings. Therefore, when evidence-based treatments are transported to the community, it is essential to investigate implementation process and outcomes. The present study assessed whether Attachment and Biobehavioral Catch-up (ABC), an intervention for high-risk parents that has been shown to be efficacious in randomized clinical trials (RCTs), changed parent behavior in a community-based setting. This study examined data collected from 78 cases by 9 parent coaches in a diverse community setting in Hawaii, and compared data to benchmarks from RCTs. Parent coach fidelity was coded from intervention session video clips, and was also compared with benchmarks. Caregivers participating in ABC were primarily birth parents, and most were referred through Child Protective Services involvement or for reasons of harsh parenting or neglect. Parental behavior was assessed before and after intervention using a semi-structured play task. Increases in parental following the lead and delight, and decreases in parental intrusiveness, were observed; these changes were comparable to effect sizes observed in RCTs. Intent to treat analyses were conducted using behavioral data from videotaped sessions, and suggested that ABC also improved following the lead in parents who subsequently dropped out of treatment. These results support the viability of ABC for enhancing parenting behavior among parents at high risk for maltreatment, and demonstrate that parent coaches in community agencies can successfully implement ABC.  相似文献
