Beyond citations: Scholars’ visibility on the social Web :

“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.”

The Accessibility Quotient: A New Measure of Open Access :

“INTRODUCTION: The Accessibility Quotient (AQ), a new measure for assisting authors and librarians in assessing and characterizing the degree of accessibility for a group of papers, is proposed and described. The AQ offers a concise measure that assesses the accessibility of peer-reviewed research produced by an individual or group, by incorporating data on open availability to readers worldwide, the degree of financial barrier to access, and journal quality. The paper reports on the context for developing this measure, how the AQ is calculated, how it can be used in faculty outreach, and why it is a useful lens to use in assessing progress towards more open access to research.

METHODS: Journal articles published in 2009 and 2010 by faculty members from one department in each of MIT’s five schools were examined. The AQ was calculated using economist Ted Bergstrom’s Relative Price Index to assess affordability and quality, and data from SHERPA/RoMEO to assess the right to share the peer-reviewed version of an article.

RESULTS: The results show that 2009 and 2010 publications by the Media Lab and Physics have the potential to be more open than those of Sloan (Management), Mechanical Engineering, and Linguistics & Philosophy.

DISCUSSION: Appropriate interpretation and applications of the AQ are discussed and some limitations of the measure are examined, with suggestions for future studies which may improve the accuracy and relevance of the AQ.

CONCLUSION: The AQ offers a concise assessment of accessibility for authors, departments, disciplines, or universities who wish to characterize or understand the degree of access to their research output, capturing additional dimensions of accessibility that matter to faculty.”

Benefits of Open Access to Scholarly Research for Voluntary and Charitable Sector Organisations :

“This study was carried out by The Office for Public Management (OPM) in partnership with the National Council of Voluntary Organisations (NCVO). We were commissioned in July 2011 by the Joint Information Systems Committee (JISC) on behalf of the Open Access Implementation Group (OAIG) to conduct research into the benefits of open access (OA) to scholarly research outputs to voluntary and community sector (VCS) organisations.”

Benefits of Open Access to Scholarly Research to the Public Sector :

“The objective of this project was to synthesise and generate evidence on the benefits that Open Access to scholarly research outputs has generated to the public sector, and to provide case studies of organisations that have realised such benefits. The project considered the benefits of Open Access for researchers in public sector organisations. It did not aim to be comprehensive in its coverage of the public sector, as there are many organisations for which research is only a very small part of their activity, and has only very limited impact on their policies and decisions. We have also focused on Open Access to research articles, as these still make up the largest proportion of research outputs used in analysis, policy and decision-making: research data is becoming more important but is still nascent in its influence in the organisations we surveyed. These organisations in any case often generate their own data through commissioned surveys and other tools as their needs tend to be very specific.”

Altmetrics in the wild: Using social media to explore scholarly impact

Posté le par

In growing numbers, scholars are integrating social media tools like blogs, Twitter, and Mendeley into their professional communications. The online, public nature of these tools exposes and reifies scholarly processes once hidden and ephemeral. Metrics based on this activities could inform broader, faster measures of impact, complementing traditional citation metrics. This study explores the properties of these social media-based metrics or “altmetrics”, sampling 24,331 articles published by the Public Library of Science.

We find that that different indicators vary greatly in activity. Around 5% of sampled articles are cited in Wikipedia, while close to 80% have been included in at least one Mendeley library. There is, however, an encouraging diversity; a quarter of articles have nonzero data from five or more different sources. Correlation and factor analysis suggest citation and altmetrics indicators track related but distinct impacts, with neither able to describe the complete picture of scholarly use alone.

There are moderate correlations between Mendeley and Web of Science citation, but many altmetric indicators seem to measure impact mostly orthogonal to citation. Articles cluster in ways that suggest five different impact “flavors”, capturing impacts of different types on different audiences; for instance, some articles may be heavily read and saved by scholars but seldom cited. Together, these findings encourage more research into altmetrics as complements to traditional citation measures.

How the Scientific Community Reacts to Newly Submitted Preprints: Article Downloads, Twitter Mentions, and Citations :

“We analyze the online response of the scientific community to the preprint publication of scholarly articles. We employ a cohort of 4,606 scientific articles submitted to the preprint database arXiv.org between October 2010 and April 2011. We study three forms of reactions to these preprints: how they are downloaded on the arXiv.org site, how they are mentioned on the social media site Twitter, and how they are cited in the scholarly record. We perform two analyses. First, we analyze the delay and time span of article downloads and Twitter mentions following submission, to understand the temporal configuration of these reactions and whether significant differences exist between them. Second, we run correlation tests to investigate the relationship between Twitter mentions and both article downloads and article citations. We find that Twitter mentions follow rapidly after article submission and that they are correlated with later article downloads and later article citations, indicating that social media may be an important factor in determining the scientific impact of an article.”

Open Access Digital Repository: Sharing Student Research with the World :

“University libraries use open access digital repositories to preserve and distribute the intellectual scholarly communications of their institution. How can global accessibility of quality student work be harnessed to benefit researchers, practitioners, and educators? To address this question, we study the impact of content factors and search engine optimization factors on download rates of capstone papers. We examined all 290 MPA capstone papers at Texas State University which have been made available through an online digital repository for public consumption. Results show strong support for the impact of search engine factors on download rates. The implications of high download rates of MPA capstone papers on public administration research, practice, and education are discussed in this paper.”
