SCI检索下环境评价研究的文献计量学评估(1996-2005)

通过对由SCI检索出的1996-2005年间所发表的1320篇以环境评价(EA)为主题词的论文文献进行计量学统计分析,探求EA研究现状和发展趋势。分析表明,近年来,EA研究保持着稳定的发展态势和对科学工作者持久的吸引力。环境科学、环境与工程是包括EA相关论文的主要分类目录,论文在不同期刊内呈分散分布,Environmental Management、Ecological Economics、Environmental Monitoring和Assessment等是主要的研究成果发表期刊。国际间合作成为主要的发展趋势,合作发表的论文在数量和影响力两方面都呈增长态势。另外,研究存在着区域间的不平衡,发达国家处于优势地位。不过,研究也显示了环境评价研究在获取学术资源方面有不容乐观的一面。

从三大检索系统收录论文看高校科研水平与学科发展——以浙江理工大学为例

采用SCI—E（即SCI网络版）、EI和ISTP三大数据库，对浙江理工大学在2004—2008五年间被收录的论文进行检索统计，运用文献计量法，对各系统收录的论文数量、收录论文的学院、学科和作者群分布及作者群的学历、职称和年龄进行统计与分析，通过定量数据从侧面了解和反映学校近几年来的科研、学科发展和人才结构情况及存在问题，以期为学校的学科建设和科研绩效评估提供数据参考，并为高校图书馆拓展信息服务内容进行有益探索。

Top-cited Articles in Chemical Engineering in Science Citation Index Expanded:A Bibliometric Analysis

This study aimed to identify and to analyze characteristics of top-cited articles published in the Web of Science chemical engineering subject category from 1899 to 2011.Articles that have been cited more than 100 times were assessed regarding publication outputs,and distribution of outputs in journals.Five bibliometric indicators were used to evaluate source countries,institution and authors.A new indicator,Y-index,was created to assess quantity and quality of contribution to articles.Results showed that 3828 articles,published between 1931 and 2010,had been cited at least 100 times.Among them 54% published before 1991,and 49% top-cited articles originated from US.The top eight productive institutions were all located in US.The top journals were Journal of Catalysis,AIChE Journal,Chemical Engineering Science and Journal of Membrane Science.Y-index was successfully applied to evaluate publication character of authors,institutions,and countries/regions.
