Relation of title length of journal articles to number of authors   总被引:2,自引:0,他引:2  
M. Yitzhaki 《Scientometrics》1994,30(1):321-332
The great importance of titles being highly informative is almost unanimously accepted in literature, assuming that the more informative titles are, the more effectively they serve their functions. The most common measure of title informativeness has been the number of substantive words included in it, and one of the factors which might be associated with it is the number of authors. The present study attempted to test, in a large group of journals fromdifferent areas, and over six decades, the hypothesis that a paper signed by a larger number of authors will have more substantive words in its title. Large samples of original research papers were drawn from each decade year of fourteen leading journals. For each paper, the number of substantive words in the title was correlated with the number of authors. Findings indicate a difference between the scientific journals on the one hand, and the social sciences and humanities journals on the other. A moderate positive correlation was found in most scientific journals (excluding mathematics) for many periods. In the social sciences journals, and to a greater extent, in the humanities journals, a significant positive correlation was limited to only a few periods, while the rest showed a very low correlation, or even a negative correlation. The different findings for the sciences may be somehow associated with their higher rate of multiple authorship.Paper presented at the Fourth International Conference on Bibliometrics, Informetrics and Scientometrics in Berlin (Germany), September 11–15, 1993.  相似文献

Previous studies produced mixed results with respect to the correlation between title length and number of citations. This research aims to provide a new explanation for this controversy by examining one of the largest pools of papers to date, containing over 300,000 economics papers spanning a much longer time period (1956–2012). The results show that correlation between title length and the number of citations is negative between 1956 and 2000, but becomes positive after 2000, when online searches became the predominant method for literature retrieval. Moreover, heterogeneity analyses show that longer titles are especially crucial for papers with relatively lower influence, which researchers can typically only access using online searches.  相似文献

This study examines the patterns of evaluation surrounding journal article comments which have appeared in theASR from 1970 through 1979. The data analyzed represent a complete enumeration of the demographic and prestige characteristics of 560 senior authors of articles, and 172 authors of comments written on 138 of the 560 articles published during the decade. Upon comparison, authors whose articles have been commented on are shown to be affiliated with significantly less prestigious institutions, than are authors whose articles have not been commented on. Furthermore, a significant inverse relationship is shown to exist between the academic ranks of article authors and comment writers.  相似文献

The purpose of this paper is to apply concepts of the diffusion of innovations research in thestudy of the international diffusion of a formerly national scientific journal, Annales ZoologiciFennici. The study was conducted using bibliometric methodology. The diffusion of the journalwas described through citations of the journal and through the development of the nationaldistribution of its contributors. The compatibility of the journal as well as the decrease ofcomplexity were found to have an influence on diffusion. Bibliometric methods were able torepresent the international diffusion of a scientific journal.  相似文献

The study discusses the necessity to analyze the influence of theoretical and empirical types of journal articles on the citation impact of Spanish psychology journals. Three of the most representative Spanish psychology journals were selected for the purposes of this study: Papeles del Psicólogo, Análisis y Modificación de Conducta and Psicothema. Twenty-three psychology journals in Spanish were used as source journals. Altogether, there were sixty-seven issues reviewed for the references and ninety-three issues for the articles. The bibliometricanalysis was conducted by six highly trained psychologists. The results demonstrated differences regarding the percentages of empirical and theoretical articles published in the three examined journals and the number of citations received by them based on the article type. When normalizing the results according to the number of theoretical and empirical articles that were published, it becomes evident that the theoretical articles receive on average twice as many references as the empirical ones. We discuss the importance of this effect on the comparison of journals based on their citation impact and show the evidence that it is only valid to compare journals which publish a similar percentage of theoretical and empirical articles.  相似文献

The problem considered is that of a steady laminar flow of an incompressible micropolar fluid in a journal bearing. A two dimensional flow field is considered and order of magnitude arguments are made, which reduce the governing balance equations to a system of coupled, ordinary differential equations. The equations are solved subject to appropriate boundary conditions and the bearing characteristics obtained. The effect of microstructure is elaborated through various graphs. The prominent feature of a micropolar fluid is an increased effective viscosity especially in thin films.  相似文献
