The purpose of this study was to examine the relationship between publication rate, top journal publications and excellence during the first eight years of the career, and how well publication rate, top journal publications and highly cited publications during the first four years of the career can predict whether an author attain excellence in the fifth to the eighth year. The dataset consisted of publication track records of 406 early career mathematicians in the sub-field of number theory collected from the MathSciNet database. Logistic regression and dominance analysis was applied to the data. The major conclusions were (1) publication rate had a positive effect on excellence during the first eighth years of the career. However, those who publish many articles in top journals, which implicitly require a high publication count, had an even higher probability of attaining excellence. These results suggest that publishing in top journals is very important in the process of attaining excellence in the early career in addition to publishing many papers; and (2) a dominance analysis indicated that the number of top journal publications and highly cited publications during the first four years of the career were the most important predictors of who will attain excellence in the later career. The results are discussed in relation to indicator development and science policy.  相似文献

This study briefly describes Karl Weick's approach to organizing and suggests its appeal to communcation scholars. Weick's model of organizing is then analyzed and clarified. Two hypotheses are proposed based on Weick's discussion of the relationship between the equivocality of information and the number of behavior cycles in organizing. The model is operationalized and tested experimentally. The results do not support Weick's suggested relationships. A reexamination of Weick's approach reveals an inconsistency between a White‐headian process perspective on organizing and a Newtonian process model of organizing. The implications of this dichotomy are suggested.  相似文献

This articles explores the political dimensions of black popular and cultural production. A main goal of the article is to consider the legacy of 1960s black nationalism and its relationship to the transformation and com‐modification of black youth expressive culture. The first part of the article examines how the changing state of black popular music in the 1960s and 1970s established some of the key tensions and contradictions that continue to influence the production of black popular music. The next part of the essay considers how the hyperpoliticization of rap music was driven by social, economic, and technological change. The final part of the article considers how a new generation of cultural producers seek to connect sixties‐styled black nationalism to the burgeoning field of digital technology and the online music industry.  相似文献

The influential Text REtrieval Conference (TREC) retrieval conference has always relied upon specialist assessors or occasionally participating groups to create relevance judgements for the tracks that it runs. Recently however, crowdsourcing has been championed as a cheap, fast and effective alternative to traditional TREC-like assessments. In 2010, TREC tracks experimented with crowdsourcing for the very first time. In this paper, we report our successful experience in creating relevance assessments for the TREC Blog track 2010 top news stories task using crowdsourcing. In particular, we crowdsourced both real-time newsworthiness assessments for news stories as well as traditional relevance assessments for blog posts. We conclude that crowdsourcing not only appears to be a feasible, but also cheap and fast means to generate relevance assessments. Furthermore, we detail our experiences running the crowdsourced evaluation of the TREC Blog track, discuss the lessons learned, and provide best practices.  相似文献

10种国际权威科技期刊影响因子构成特征及其启示   总被引:1,自引:0,他引:1  
刘雪立 《编辑学报》2014,26(3):296-300
利用Web of Science(WoS)数据库和Journal Citation Reports(期刊引证报告,JCR)的引证分析功能,从3个方面探讨10种国际权威期刊影响因子的结构特征:1)自引对影响因子的贡献;2)不同类型文献对影响因子的贡献;3)高被引论文对影响因子的贡献。结果显示:10种国际权威期刊自引对其影响因子的贡献率均较低;研究论文(article)和综述(review)对影响因子的贡献率均在80%以上,述评(editorial)、信稿(letter)和科技新闻(news item)对科技期刊影响因子的贡献不容忽视,其他类型的文献对影响因子贡献较小;各期刊高被引论文对影响因子的贡献率普遍较高。提示:增加期刊自引在一定程度上可以提高影响因子,但依靠增加自引来提高期刊实际影响力几乎是不可能的;科学规划期刊的文献类型,多发表一些述评、信稿和科技新闻等类型的文献对提高期刊的影响因子和影响力是很有价值的;通过引文分析寻找相关学科领域的研究前沿和热点,加强高被引论文的选题策划是提高科技期刊影响因子的有效方法。  相似文献
