(www.springerlink.com/content/k725047l0u143222/fulltext.pdf) The authors propose a new bibliometric index that is the “tapered h-index”. The h-index of an individual scientist corresponds to the number h of his/her papers that each has at least h citations. The citation count of an article can exceed h, and for hundreds or thousands of citations that characterize the most highly cited papers, no additional credit is given. This new index positively scores all citations, and it shows smooth increases from year to year. Ball P. A longer paper gathers more citations. Nature 2008;455:274–275. (doi:10.1038/455274a) In an analysis of 30,027 peer-reviewed papers published between 2000 and 2004 in top astronomy journals, the median number of citations increased with the length of the paper, starting to tail off when papers reach lengths of 80 pages or so. The study highlights some important questions: in the face of new dissemination channels, is it realistic to regard citations as an accurate measure of achievement, and how long should a paper be, if length really does matter.

(doi: 10.1007/s11192-007-1892-8) Factors contributing to citation impact in social-personality psychology were examined in a bibliometric study of articles published in the field’s three major journals. Impact was operationalized as citations accrued over 10 years by 308 articles published in 1996, and predictors were assessed using multiple databases and trained coders. Multivariate analyses demonstrated several strong predictors of impact, but many variables did not predict impact. © Copyright 2009 by European Association of Science Editors Top of Page |
