为了揭示“h指数族”各项指数的相关性特点,对山东省内57所本科高校图书馆科研影响力进行综合实证研究,为图书馆工作者及相关机构进行馆际科研评价、交流和培训等提供决策依据。文章以《中国引文数据库》为数据源,用“h指数族”各项指数对评价机构在1996--201O年的论文数量和总被引频次进行统计分析。结论如下：鲁东大学图书馆h指数族取值特性异常显著;烟台大学图书馆等h指数族排名位次靠前;泰山医学院图书馆具备相当数量的潜在高被引论文,预期其科研影响力将会有显著提升。h指数族与论文数量和被引频次之间呈幂律关系,h指数族两两之间呈线性关系。图书馆h指数族取值随着图书馆论文数量和总被引频次的增长存在“规模效益递减”现象;图书馆应该密切关注能提升其g指数的潜在高被引论文,从而实现提升h指数和s指数、不断提高科研影响力的愿望。 相似文献

[目的/意义] 鉴于"科学-技术关系"是情报学领域的热点研究问题,文献计量方法是研究该问题的常用方法,对国内外研究该问题的主要文献计量方法进行述评,就如何更好地运用这些方法进行"科学-技术关系"研究提出建议。[方法/过程] 在回顾"科学-技术关系"的含义和相关研究方法的基础上,梳理和总结专利的论文引文分析法、论文的专利引文分析法、"专利发明人-论文作者关联关系"分析法3种主要文献计量方法在"科学-技术关系"研究方面的应用和国内外进展,比较3种方法的理论基础、应用范围和存在的问题。[结果/结论] 3种方法基于不同的理论基础,分别被应用于:①识别与科学领域关系较强的技术领域;②识别被科学领域引用较多的技术领域、国家和机构;③测度专利发明人的科学研究活动、大学和企业的合作情况。这些方法分别存在专利的施引动机不明确、专利的论文引文字段不规范、数据较少、主题分析和技术对科学的作用机理研究较少、专利发明人和论文作者名称难以识别和匹配等问题。研究"科学-技术关系"时需根据研究问题和数据特征等选择合适的文献计量方法,并注意解决这些方法存在的问题。 相似文献

A proposal is made in this paper for a broadening of perspective in evaluative bibliometrics by complementing the (standard) times cited with a cited reference analysis for a field-specific citation impact measurement. The times cited approach counts the citations of a given publication set. In contrast, we change the perspective and start by selecting all papers dealing with a specific research topic or field (the example in this study is research on Aspirin). Then we extract all cited references from the papers of this field-specific publication set and analyse which papers, scientists, and journals have been cited most often. In this study, we use the Chemical Abstracts registry number to select the publications for a specific field. However, the cited reference approach can be used with any other field classification system proposed up to now. 相似文献

Objectives
This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.Method
Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.Results
Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.Conclusion
Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field. 相似文献19.

Objectives:
The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.Method:
Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.Results:
Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.Conclusions:
Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.Highlights
- More cited references were published in the last eight years studied than in any previous full decade.
- Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
- CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.
Implications
- Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
- Multiple databases are needed for comprehensive coverage of the physical therapy discipline
