Does Online Availability Increase Citations? Theory and Evidence from a Panel of Economics and Business Journals :

“Does online availability boost citations? The answer has implications for issues ranging from the value of a citation to the sustainability of open-access journals. Using panel data on citations to economics and business journals, we show that the enormous effects found in previous studies were an artifact of their failure to control for article quality, disappearing once we add fixed effects as controls. The absence of an aggregate effect masks heterogeneity across platforms: JSTOR stands apart from others, boosting citations around 10%. We examine other sources of heterogeneity including whether JSTOR increases cites from authors in developing more than developed countries and increases cites to “long-tail” more than “superstar” articles. Our theoretical analysis informs the econometric specification and allows us to translate our results for citation increases into welfare terms.”

On the impact of Gold Open Access journals…

Statut

On the impact of Gold Open Access journals :

“Gold Open Access (=Open Access publishing) is for many the preferred route to achieve unrestricted and immediate access to research output. However, true Gold Open Access journals are still outnumbered by traditional journals. Moreover availability of Gold OA journals differs from discipline to discipline and often leaves scientists concerned about the impact of these existent titles. This study identified the current set of Gold Open Access journals featuring a Journal Impact Factor (JIF) by means of Ulrichsweb, Directory of Open Access Journals and Journal Citation Reports (JCR). The results were analyzed regarding disciplines, countries, quartiles of the JIF distribution in JCR and publishers. Furthermore the temporal impact evolution was studied for a Top 50 titles list (according to JIF) by means of Journal Impact Factor, SJR and SNIP in the time interval 2000–2010. The identified top Gold Open Access journals proved to be well-established and their impact is generally increasing for all the analyzed indicators. The majority of JCR-indexed OA journals can be assigned to Life Sciences and Medicine. The success-rate for JCR inclusion differs from country to country and is often inversely proportional to the number of national OA journal titles. Compiling a list of JCR-indexed OA journals is a cumbersome task that can only be achieved with non-Thomson Reuters data sources. A corresponding automated feature to produce current lists ‘‘on the fly’’ would be desirable in JCR in order to conveniently track the impact evolution of Gold OA journals.”

EU FP7 Research in Open Access Repositories …

Statut

EU FP7 Research in Open Access Repositories :

“Open access repositories are a reliable source of academic items that can be used for testing the capabilities of the webometric analysis. This paper deals with actions needed for extracting web indicators from bibliographic records in open access repositories, provides guidelines to support a further webometric study and presents the results of a preliminary web impact evaluation carried out over a sample of 1,386 EU FP7 output papers available from the OpenAIRE database. The European Commission project OpenAIRE aims, among other objectives, to provide impact measures to assess the research performance from repositories contents and, especially, of Special Clause 39 project participants within EU FP7. Using URL citations, title mentions and copies of titles as main web impact indicators, this study suggests that a priori the implementation of the mandatory clause SC39 to encourage open access to European research may be resulted indeed in a greater and more immediate web visibility of these papers.”

Beyond Citations: Scholars’ Visibility on the Social Web

Posté le par

Traditionally, scholarly impact and visibility have been measured by counting publications and citations in the scholarly literature. However, increasingly scholars are also visible on the Web, establishing presences in a growing variety of social ecosystems.

But how wide and established is this presence, and how do measures of social Web impact relate to their more traditional counterparts? To answer this, we sampled 57 presenters from the 2010 Leiden STI Conference, gathering publication and citations counts as well as data from the presenters’ Web “footprints.”

We found Web presence widespread and diverse: 84% of scholars had homepages, 70% were on LinkedIn, 23% had public Google Scholar profiles, and 16% were on Twitter. For sampled scholars’ publications, social reference manager bookmarks were compared to Scopus and Web of Science citations; we found that Mendeley covers more than 80% of sampled articles, and that Mendeley bookmarks are significantly correlated (r=.45) to Scopus citation counts.”

F1000, Mendeley and Traditional Bibliometric Indicators

Posté le par

This article compares the Faculty of 1000 (F1000) quality filtering results and Mendeley usage data with traditional bibliometric indicators, using a sample of 1397 Genomics and Genetics articles published in 2008 selected by F1000 Faculty Members (FMs). Both Mendeley user counts and F1000 article factors (FFas) correlate significantly with citation counts and associated Journal Impact Factors. However, the correlations for Mendeley user counts are much larger than those for FFas.

It may be that F1000 is good at disclosing the merit of an article from an expert practitioner point of view while Mendeley user counts may be more closely related to traditional citation impact. Articles that attract exceptionally many citations are generally disorder or disease related, while those with extremely high social bookmark user counts are mainly historical or introductory.

La visibilité des revues scientifiques francophones sur le plan international : le cas des SIC et d’Études de Communication

Posté le par

“Les Sciences de l’Information et de la Communication sont une discipline spécifiquement française. Les anglo-saxons ont maintenus la différence entre, d’une part, la Library and Information Science et les Communication and Media Studies. Appartenant au champ des SIC la revue Études de Communication aborde à la fois des thématiques propres au champ de la LIS et au champ des media studies. La visibilité des revues francophones à l’international, dans un monde qui s’anglicise de plus en plus, est problématique. Quand le champ scientifique dans lequel s’inscrit une revue n’existe pas en-dehors de la francophonie cette problématique s’intensifie. Il s’agit ici de définir la notion de visibilité et ses enjeux, en général et dans le champ plus spécifique des SIC, de s’interroger sur la place du français dans le monde scientifique et d’envisager un cas pratique, celui d’Études de Communication, avec ses caractéristiques et ses solutions.”
