One problem confronting the use of citation-based metrics in science studies and research evaluations is the Matthew effect. This paper reviews the role of citations in science and decomposes the Matthew effect in citations into three components: networking, prestige, and appropriateness. The networking and prestige effects challenge the validity of citation-based metrics, but the appropriateness effect does not. Using panel data of 1279 solo-authored papers’ citation histories and fixed effects models, we test these three effects controlling for unobserved paper characteristics. We find no evidence of retroactive networking effect and only weak evidence of prestige effect (very small and not always significant), which provides some support for the use of citation-based metrics in science studies and evaluation practices. In addition, adding the appropriateness effect reduces the size of the prestige effect considerably, suggesting that previous studies controlling for paper quality but not appropriateness may have overestimated the prestige effect.  相似文献

This paper reports on the first documented attempt to investigate the presence of the superstar (or Matthew) effect in the knowledge management and intellectual capital (KM/IC) scholarly discipline. The Yule–Simon model and Lotka's square law were applied to the publication data obtained from 2175 articles from 11 KM/IC journals. Based on the findings, it was concluded that the KM/IC discipline represents a very young, attractive academic field that welcomes contributions from a variety of academics and practitioners. In their paper acceptance decisions, KM/IC journal editors are not biased towards a small group of highly productive researchers, which is a positive sign that the field has been progressing in the right direction. The discipline is driven more by academics than by practitioners, and the distribution of articles is more concentrated among a few academic but not practitioner institutions. It was also observed that the Yule–Simon model and Lotka's square law may produce different distributions with respect to institutions.  相似文献

In the competitive world of children's programming, networks are under intense pressure to build brand loyalty and increase market share. This essay examines how Fox Kids and the Disney Channel transform electronic space into “place” as a means for carving out brand identity. This transformation of electronic space into place requires strategies that encourage viewers to see electronic spaces as habitable and desirable. While the two networks employ different approaches to the creation of place, they both reproduce familiar ideologies (e.g., individuality as identity) and social arrangements (e.g., families and neighborhoods) to represent a habitable place that can inspire loyalty and even affection from viewers.  相似文献

ABSTRACT

This article aims to demonstrate how to objectively select the best children's librarian from all children's librarian candidates by using OWA (Ordered Weighted Averaging) technique as a new model. Firstly, we described 14 professional criteria that must be met by 4 different candidates (c1, c2, c3, and c4). Secondly, we determined ‘the importance weights of professional criteria (u)’ and ‘the extent to which the children's librarian candidates meet these criteria (b)’. In order to determine the values of u and b, we changed the linguistic values such as good, bad, or important into the numerical values. Thirdly, we calculated the final performance scores of all children's librarian candidates by using the formula OWA. Finally, we selected the candidate 4 (c4) who earned the highest score (0,645) in total as the best children's librarian.  相似文献

For hundreds of years, bibliographies have been invaluable tools for researchers, collectors, and institutions, to provide contextual understanding as well as adding depth to collections. In this piece, the author uses his updated bibliography of the first 200 years of Littleton's Tenures to examine many aspects of early English legal printing. These include the development and evolution of the content of early legal materials, as well economic and other factors driving the market for printed law books. Preceding the bibliography is a list of fundamental bibliographic terms concerning early printing, contextually applied to Littleton's Tenures.  相似文献

With the acquisition of the Wilson Multi-Database Access (MDAS) product, the potential for efficient research processes increased the likelihood of a greater impact of interlibrary of a greater impact on interlibrary requests and current periodical usage. To measure this impact, this study was designed to gather data on ILL requests from titles in the three indexes that comprise the MDAS product. Data waz gathered for comparable time periods prior to the installation of MDAS and afterwards. Similar use data was collected for current periodical issues. This study shows that a potentially greater impact was realized.  相似文献

第三人效应理论:传播效果研究的新视角   总被引:8,自引:0,他引:8  
20世纪 80年代以来 ,第三人效应理论作为传播效果研究的一个新内容 ,已经在西方传播学界产生了较大的影响。该理论的基本观点是 ,受众普遍认为大众传媒对其他人的影响要比对自己的要大 ;但在进一步的研究中 ,发现第一人效应和第三人效应之间还存在着某些矛盾之处 ,这集中体现在“互有差异的认知”这个概念上。这个理论对于解释目前传播中存在的一些问题和现象有着重要的启发意义。  相似文献

ABSTRACT

This study investigated the post-master's educational needs and interests of information professionals. The population for the study consisted of members of the library associations of Michigan, Ohio, Indiana, and Ontario, Canada. About 78 percent of the respondents held a master's degree in library science, 22 percent a master's degree in another discipline, almost 1 percent was enrolled in a doctoral program, 1 percent possessed a doctorate, and 16 percent had some other degree. Given the choice of an LIS only doctoral program or one combined with the field of business administration or computer science, the participants expressed a slight preference for the LIS only program. Of the other fields suggested by participants, education and public administration were the most popular. Participants also expressed a strong preference for non-traditional modes of instruction.  相似文献

This article examines the ethos and rationale of The Woman Worker, launched in Britain in September 1907 as the official organ of the all-female trade union, the National Federation of Women Workers (the Federation). As a monthly journal, it was edited and managed by Mary Macarthur, President of the Federation, moving to weekly production in June 1908 with the assistance of Robert Blatchford, founder of the successful socialist newspaper, The Clarion. Under Macarthur, the paper emphasised both the importance of union organisation for women workers and the need for parliamentary legislation to protect them from low pay, victimisation and exploitation in the workplace. It is argued here that although this paper sought to fill a gap in the market, producing a paper that appealed beyond those already converted to the cause of women's organisation was a difficult challenge for Macarthur. Her attempts to provide a readable but didactic paper on a limited budget, relying on Labour colleagues for copy, resulted in a paper that did not always have a clear target readership; it was a union journal seeking broad appeal amongst working-class women but it also reflected the interests of committed labour activists. This arguably resulted in a paper that struggled to achieve its initial aim of binding women workers together.  相似文献

This study used a content analysis of editorial articles to explore the portrayal of gender in women's pages of Taiwanese newspapers between 1975 and 2009. In addition to topical themes and editorial format, we focused on how women's pages present political messages in terms of the topics addressed, style of argumentation, methods of challenging traditional gender roles, and the promotion of provocative actions. We compared the content analysis data with social development indicators and public opinion polls in the contexts of the evolution of the market and the women's movement in Taiwan. We found that in the early stages of the women's movement, the women's pages mainly played the role of shaping a collective identity among the female public. During the postfeminist period, the women's pages mainly address social problems rooted in the domestic realm and provide self-development advice.  相似文献
