The present study means to establish to what extent high-quality open access journals are available as an outlet for publication, by examining their distribution in different scientific disciplines, including the distribution of those journals without article processing charges.
The study is based on a systematic comparison between the journals included in the DOAJ, and the journals indexed in the Journal Citation Reports (JCR) Science edition 2013, released by Thomson Reuters.
The impact factor of Open Access (OA) journals was lower than those of other journals by a small but statistically significant amount. Open access journals are present in the upper quartile (by impact factor) of 85 out of 176 (48.8%) categories examined. There were no OA journals with an Impact Factor in only 16 categories (9%).

We propose a new performance indicator to evaluate the productivity of research institutions by their disseminated scientific papers. The new quality measure includes two principle components: the normalized impact factor of the journal in which paper was published, and the number of citations received per year since it was published. In both components, the scientific impacts are weighted by the contribution of authors from the evaluated institution.
As a whole, our new metric, namely, the institutional performance score takes into account both journal based impact and articles specific impacts. We apply this new scheme to evaluate research output performance of Turkish institutions specialized in astronomy and astrophysics in the period of 1998-2012. We discuss the implications of the new metric, and emphasize the benefits of it along with comparison to other proposed institutional performance indicators.

« This report presents the findings and recommendations of the Independent Review of the Role of Metrics in Research Assessment and Management. The review was chaired by Professor James Wilsdon, supported by an independent and multidisciplinary group of experts in scientometrics, research funding, research policy, publishing, university management and administration.
This review has gone beyond earlier studies to take a deeper look at potential uses and limitations of research metrics and indicators. It has explored the use of metrics across different disciplines, and assessed their potential contribution to the development of research excellence and impact. It has analysed their role in processes of research assessment, including the next cycle of the Research Excellence Framework (REF). It has considered the changing ways in which universities are using quantitative indicators in their management systems, and the growing power of league tables and rankings. And it has considered the negative or unintended effects of metrics on various aspects of research culture. »

« With the rise of Wikipedia as a first-stop source for scientific knowledge, it is important to compare its representation of that knowledge to that of the academic literature. This article approaches such a comparison through academic references made within the worlds 50 largest Wikipedias. Previous studies have raised concerns that Wikipedia editors may simply use the most easily accessible academic sources rather than sources of the highest academic status. We test this claim by identifying the 250 most heavily used journals in each of 26 research fields (4,721 journals, 19.4M articles in total) indexed by the Scopus database, and modeling whether topic, academic status, and accessibility make articles from these journals more or less likely to be referenced on Wikipedia.
We find that, controlling for field and impact factor, the odds that an open access journal is referenced on the English Wikipedia are 47% higher compared to closed access journals. Moreover, in most of the worlds Wikipedias a journals high status (impact factor) and accessibility (open access policy) both greatly increase the probability of referencing. Among the implications of this study is that the chief effect of open access policies may be to significantly amplify the diffusion of science, through an intermediary like Wikipedia, to a broad public audience. »
