中国科技论文与引文数据库所收录的论文来自约2 000种中国科技核心期刊.从2012年开始,对中国科技核心期刊所刊载的文献进行了更详细的分类标引,共分为“论著”“综述和评论”“短篇论文和研究快报”“工业工程设计”“研究材料和标准文献”“交流材料”“书评”“社论”“消息动态”“译文”“文摘和其他”等11类文献类型.通过统计分析发现:“论著”类型的论文是份额最大的文献类型,且保持着持续增长的态势;“综述和评论”文献被引用规模比较大,被引用速度也比较快,但是从文献数量上看,在全部文献中所占比例比较少,且数量规模也相对稳定;“短篇论文和研究快报”类文献被引用的规模和比例与“论著”类型文献差距较大;“交流材料”类文献所产生的学术影响很小,约6成在发表之后3年内不会得到引用. 相似文献

由Web of Science数据库分析高影响力中华医学会系列期刊引发的思考 总被引：4，自引：0，他引：4
通过Web of Science数据库的“被引参考文献检索”途径,将中华医学会123种非SCI期刊作为国内大量的非SCI科技期刊的代表,统计其刊载文献被SCI期刊引用的情况;以被引文献数量大于50篇作为高影响力期刊的筛选条件,分析其中高影响力期刊的被引文献数量、单篇被引文献最高引用频次、施引文献数量、施引文献最高被引频次以及施引文献的国家地区分布、出版年份分布,从而了解这些非SCI科技期刊的国际影响力.基于这一分析,认为SCI期刊并非是获得同行认可的唯一途径,国内大量的非SCI科技期刊应走“立足国内,面向世界”的发展道路,以踏实做专业领域内有影响力的期刊为目标;同时呼吁国家有关部门能对现行科研评价指标进行调整,鼓励质量上乘的稿件能选择具有影响力的国内期刊发表. 相似文献

阐述科技期刊学术论文文后参考文献中"题名"这一关键信息要素的判定、引导和检索的功能,强调应当重视文后参考文献"题名"的著录。认为国内知名期刊须更加注重文献题名的规范标注,充分发挥在同行期刊中的示范和引导作用,不应单纯以符合"国际惯例"为由而采取省略题名的做法。 相似文献

当前我国科技期刊发展中的一些误区 总被引：24，自引：5，他引：19
指出当前我国科技期刊发展中存在的误区：部分人士对科技期刊的功能认识不足，未能正确评价期刊被美国科学引文索引（SCI）收录的价值，期刊为提高知名度所采取的方式欠妥，对国内外期刊发表的论文未能公正评价，论文关键词的标引不规范，电子版期刊的发展对印刷版期刊的要求太高；并提出了针对这些误区的改进意见。 相似文献

历史影响因子:一个新的学术期刊存量评价指标 总被引：3，自引：0，他引：3
[目的/意义]期刊评价指标是期刊某个视角水平的综合体现,因此有必要必须不断深化和发展;提出一个新的期刊存量指标--历史影响因子,就是期刊总被引频次除以载文量再除以办刊年限。[方法/过程]以科技管理类期刊为例,基于中国知网数据库CNKI,采用相关系数、聚类分析、岭回归进行了实证。[结果/结论]研究表明,历史影响因子兼有影响因子和h指数的优点,克服了传统期刊评价指标存量指标过少、不考虑期刊办刊时间、不考虑期刊载文数量等局限,是一个较好的期刊评价指标。历史影响因子没有考虑期刊自引问题,而且不同的引文数据库对历史影响因子的影响也比较大,在具体应用时可根据需要排除自引或选择其他引文数据库。 相似文献

Objective:This study aims to identify the core journals cited in the health care management literature and to determine their coverage in the foremost bibliographic databases used by the discipline.Methods:Using the methodology outlined by the Medical Library Association''s Nursing and Allied Health Resource Section (NAHRS) protocol for “Mapping the Literature of Nursing and Allied Health Professions,” this study updates an earlier study published in 2007. Cited references from articles published in a three-year range (2016–2018) were collected from five health care management journals. Using Bradford''s Law of Scattering, cited journal titles were tabulated and ranked according to the number of times cited. Eleven databases were used to determine coverage of the most highly cited journal titles for all source journals, as well as for a subset of practitioner-oriented journals.Results:The most highly cited sources were journals, followed by government documents, Internet resources, books, and miscellaneous resources. The databases with the most complete coverage of Zone 1 and 2 were Scopus, Web of Science Core Collection, and PubMed, while the worst performing databases were Health Business Elite, ABI/Inform, and Business Source Complete.Conclusions:The literature of health care management has expanded rapidly in the last decade, with cumulative citations increasing by 76.6% and the number of cited journal titles increasing by nearly 70% since the original study. Coverage of the core journals in popular databases remains high, although specialized health care management and business databases did not perform as well as general or biomedical databases. 相似文献

《Legal Reference Services Quarterly》2013,32(2-3):99-112
Abstract Several studies have compared the frequency of citation to law reviews, comparing citation rates for all or most law reviews being published at the time of the study. This article compares the citation rates of general law reviews published by seven public law schools in close geographic proximity. The results show that citation rates are influenced by several factors, including whether articles published by the journals have a state or national focus, the subject matter of the articles, and whether articles are published as part of symposia. 相似文献

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
