Do highly productive researchers have significantly higher probability to produce top cited papers? Or does the increased productivity in science only result in a sea of irrelevant papers as a perverse effect of competition and the increased use of indicators for research evaluation and accountability focus? We use a Swedish author disambiguated data set consisting of 48,000 researchers and their WoS-publications during the period of 2008 2011 with citations until 2014 to investigate the relation between productivity and production of highly cited papers. As the analysis shows, quantity does make a difference.

Tenure-Track Science Faculty and the ‘Open Access Citation Effect’ :
« INTRODUCTION : The observation that open access (OA) articles receive more citations than subscription-based articles is known as the OA citation effect (OACE). Implicit in many OACE studies is the belief that authors are heavily invested in the number of citations their articles receive. This study seeks to determine what influence the OACE has on the decision-making process of tenure-track science faculty when they consider where to submit a manuscript for publication.
METHODS : Fifteen tenure-track faculty members in the Departments of Biology and Chemistry at the University of North Carolina at Chapel Hill participated in semi-structured interviews employing a variation of the critical incident tecnique.
RESULTS Seven of the fifteen faculty members said they would consider making a future article freely-available based on the OACE. Due to dramatically different expectations with respect to the size of the OACE, however, only one of them is likely to seriously consider the OACE when deciding where to submit their next manuscript for publication.
DISCUSSION Journal reputation and audience, and the quality of the editorial and review process are the most important factors in deciding where to submit a manuscript for publication. Once a subset of journals has satisfied these criteria, financial and access issues compete with the OACE in making a final decision.
CONCLUSION In order to increase the number of OA materials, librarians should continue to emphasize depositing pre- and post-prints in disciplinary and institutional repositories and retaining the author rights prior to publication in order to make it possible to do so. »

Linking to Data – Effect on Citation Rates in Astronomy :
« Is there a difference in citation rates between articles that were published with links to data and articles that were not? Besides being interesting from a purely academic point of view, this question is also highly relevant for the process of furthering science. Data sharing not only helps the process of verification of claims, but also the discovery of new findings in archival data. However, linking to data still is a far cry away from being a « practice », especially where it comes to authors providing these links during the writing and submission process. You need to have both a willingness and a publication mechanism in order to create such a practice. Showing that articles with links to data get higher citation rates might increase the willingness of scientists to take the extra steps of linking data sources to their publications. In this presentation we will show this is indeed the case: articles with links to data result in higher citation rates than articles without such links. The ADS is funded by NASA Grant NNX09AB39G. »

Self-Selected or Mandated, Open Access Increases Citation Impact for Higher Quality Research :
Articles whose authors have supplemented subscription-based access to the publisher’s version by self-archiving their own final draft to make it accessible free for all on the web (“Open Access”, OA) average twice as many citations as articles in the same journal and year that have not been made OA. Some have suggested that this “OA Advantage” may not be causal but just a self-selection bias, because authors preferentially make higher-quality articles OA. To test this we compared self-selective
self-archiving with mandatory self-archiving for a sample of 27,197 articles published 2002-2006 in 1,984 journals.
Principal Findings: The OA Advantage proved just as high for both. Logistic regression analysis showed that the advantage is independent of other correlates of citations (article age; journal impact factor; number of co-authors, references or pages; field; article type; or country) and greatest for the most highly cited articles. The OA Advantage is real, independent and causal, but skewed. Its size is indeed correlated with quality, just as citations themselves are (the top 20% of articles receive about 80% of all citations).
The OA advantage is greater for the more citable articles, not because of a quality bias from authors self-selecting what to make OA, but because of a quality advantage, from users self-selecting what to use and cite, freed by OA from the constraints of selective accessibility to subscribers only. It is hoped that these findings will help motivate the adoption of OA self-archiving mandates by universities, research institutions and research funders. »
