近几年我国气象期刊的总体情况及文献计量统计分析 总被引：1，自引：0，他引：1
潘魏伟 《中国科技期刊研究》2008,19(6):998-1003
总结了近几年气象专业期刊的总体变化情况,并对公开出版期刊的期刊评价指标值进行了简单的统计比较,结果表明：气象类期刊内刊的数量不少,占25％;多数期刊版权页信息不全面,编校质量需要提高;学术类期刊多由季刊改为双月刊、由16开改为A4开本;有些省气象局主办的期刊更改刊名和办刊宗旨后,走含有特色报道的学术期刊发展道路;除了核心期刊外,多数公开出版的期刊评价指标值处于较低水平,改刊名后的学术期刊的评价指标值增长较快。 相似文献

数字环境下高校图书馆纸质期刊资源的订购与利用 总被引：1，自引：0，他引：1
随着数字技术、网络技术的快速发展及广泛应用,高校图书馆的大环境发生了巨大变化,期刊作为图书馆资源建设的重要组成部分,同样发生着深刻的变革.通过对纸质期刊与电子期刊的比较分析,认为纸质期刊与电子期刊各有局限性和优势,二者可以共存、互补,因此,在现阶段二者是相互依存、相互促进的,并探讨了在数字环境下高校图书馆馆藏由单一的纸质期刊资源向多类型、多载体期刊资源方向转变过程中纸质期刊资源的订购与利用的问题. 相似文献

Measuring the output of men and women in science and technology has previously been mostly restricted to case studies or small-scale surveys. Based on an analysis of patent and publication databases, this paper applies a methodology to systematically assign the gender to the names of inventors and authors. The method is applied to 14 countries. The results of this investigation reveal substantial differences across countries in terms of women's relative contribution1 to science and technology, with the central European countries of Germany, Austria and Switzerland all ranking comparatively low in this respect. We also examine trends over time, showing that the data on women's share of publications - unlike the results for patents - hardly increase over time for the already better-performing nations. 相似文献

This paper studies the transdisciplinary impact of scientific publications with a longitudinal, comprehensive, and large-scale analysis on the Microsoft Academic Graph (MAG) dataset. More specifically, this paper aims to understand to what extent publications in discipline A have impact on discipline B. To this end, we propose a novel method to characterize the degree to which a publication impacts another discipline instead of its original discipline. We consider the ratio of the number of citations in a certain discipline and that in the original discipline. We also adopt an OLS regression to identify the equation between the ratio and the affinity of discipline pair and find a clear positive relation. This inspires us to categorize a publication's degree of transdisciplinarity by setting up two thresholds, the top 95% and the bottom 95% confident interval curve (of the fitted line). Publications above the top 95% curve is categorized as transdisciplinary ones, those below the bottom 95% curve as domain-specific ones, and those between the two curve as normal publications. This categorization does not require any pre-defined framework for transdisciplinarity and offers an automatic way of definition by data distribution itself. We find that sociology, mathematics, physics, and chemistry account for a great proportion of transdisciplinary publications that influence other domains, and that medicine, biology, economics, and geology have the greatest proportion of domain-specific publications that show impact in the original discipline. Moreover, we observe a negative relation between the number of citations and the proportion of transdisciplinary publications. A longitudinal analysis presents that the proportion of transdisciplinary publications shows a slightly increase trend for years. 相似文献

The Nobel Prize has been a prominent research topic in Scientometrics. This study aims to explore Nobel citation effects, which refer to changes in the cumulative citation counts of publications after authors have won the Nobel Prize. In this study, we propose an exchangeability verification method to ensure samples in experimental group (EG) and control group (CG) are indistinguishable based on relatively few covariates. Then, we quantify Nobel citation effects by employing the propensity score matching strategy. Finally, we combine the matching strategy with statistical tests to ensure the reliability of the conclusions. We find that publications in 18 topics have significant and positive Nobel citation effects among the 50 topics in Physics, that is, when authors of publications belonging to one of the 18 topics won the Nobel Prize, the post-award citation counts of their publications would increase. Besides, we find that the Nobel citation effects are long term, lasting for 47 years or more. Finally, we find Nobel citation effects are significant and positive for publications whose authors won the Nobel Prize before the 1980s. 相似文献

We explore the contention that the seminal US National Academies consensus report, How People Learn (HPL), played a major role in bridging the flow of knowledge from Cognitive Science to Education. Our paper yielded four important results: First, HPL is, on a number of bibliometric measures, an unusually interdisciplinary work. Focusing on the fields of particular interest here, our citation analysis shows the Education, Cognitive Science, and Border field (e.g., Educational Psychology, Learning Sciences, and Learning Technology and Human-Computer Interaction) literatures all to have been major influences on it. Second, we found HPL to be unusually highly cited – and by publications from an unusually diverse set of disciplines. Beyond Education, Cognitive Science, and Border field publications, HPL was also relatively highly cited by publications in Medical/Health-related, Engineering, and other Discipline-Based Education Research fields. Third, undermining the claim that HPL served as a gateway to the Cognitive Science literature, we found Education articles citing HPL not to be more likely to have Cognitive Science as a major influence than are Education articles more generally, as indicated by their cited references. Finally, the Education publications that cited HPL were far more likely to refer to concepts in HPL that were already prevalent in the Education literature rather than to concepts from Cognitive Science. Conversely, the Cognitive Science publications that cited HPL were more apt to refer to concepts already in the Cognitive Science literature. Taken together, these results are a caution that, even for a highly regarded multidisciplinary work cited widely by publications from multiple disciplines, its direct influence could be largely disciplinary. Implications for the policy goals of fostering interdisciplinary research and the role of National Academies consensus reports are discussed. 相似文献

论学会发表与新颖性丧失的例外 总被引：1，自引：0，他引：1
柳申一 《科学．经济．社会》2006,24(4):63-66
使发明创造取得专利,可以排除第三人实施相同的发明创造,回避第三者的重复投资的风险。大学及研究机构的学者、科研人员的成果,在发明创造中占有重要的地位。而学会发表、论文发表又是大学、研究机构的学者、科研人员展示研究成果的优先性、提高声誉、增加交流的重要途径。如何解决学会发表与专利新颖性丧失的矛盾是非常重要的。因此,必须充分理解新颖性丧失的例外的本质和条件,更加合理地应用这一制度,促进学者、科研人员的研究成果专利化的进程。 相似文献
