Citation of Open Access Resources by African Researchers in Corrosion Chemistry :

“The authors performed a citation analysis of 15 source papers that were written in the field of corrosion chemistry. Each of the source papers was written on the specific topic of the corrosion of mild steel. The researchers were from a variety of different countries, including China, Egypt, Germany, India, Lesotho, Nigeria, Saudi Arabia, South Africa, Spain, Turkey, and the United States. The authors found that articles that had one or more researchers from an African country cited works that had versions in the Open Access (OA) domain twice as often (12.2%) when compared to articles that did not have an author from Africa (5.5%). The authors also evaluated the types of Open Access resources that the researchers cited, and the error rates found within their citations.”

A measure of total research impact independent of time and discipline :

“Authorship and citation practices evolve with time and differ by academic discipline. As such, indicators of research productivity based on citation records are naturally subject to historical and disciplinary effects. We observe these effects on a corpus of astronomer career data constructed from a database of refereed publications. We employ a simple mechanism to measure research output using author and reference counts available in bibliographic databases to develop a citation-based indicator of research productivity. The total research impact (tori) quantifies, for an individual, the total amount of scholarly work that others have devoted to his/her work, measured in the volume of research papers. A derived measure, the research impact quotient (riq), is an age independent measure of an individual’s research ability. We demonstrate that these measures are substantially less vulnerable to temporal debasement and cross-disciplinary bias than the most popular current measures. The proposed measures of research impact, tori and riq, have been implemented in the Smithsonian/NASA Astrophysics Data System.”

On the Citation Advantage of linking to data :

“This paper present some indications of the existence of a Citation Advantage related to linked data, using astrophysics as a case. Using simple measures, I find that the Citation Advantage presently (at the least since 2009) amounts to papers with links to data receiving on the average 50% more citations per paper per year, than the papers without links to data. A similar study by other authors should a cummulative effect after several years amounting to 20%. Hence, a Data Sharing Citation Advantage seems inevitable.”

Information research : an internatinal electronic journal : a bibliometric study :

“At present bibliometric study is an interacting research topic in the field of library and information science. Library and information science professionals are doing bibliometric study in various fields for the collection development of different subject in their libraries. This paper examines that the Bibliometric Analysis of the Information Research: an International Electronic Journal (IRIEJ). Which is included the study of form of documents, authorship pattern, ranking of authors, year wise distribution of references and articles, ranking of cited journals, cited publishers and research contributors of IRIEJ.”

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 Effect of Free Access on the Diffusion of Scholarly Ideas :

“This study examines a relationship between free access to research articles and the diffusion of their ideas as measured by citation counts. While free access should, in theory, help the diffusion of ideas, many researchers have debated the existence of the benefit of free access: reported empirical findings range from zero or negative effect to an over 300% increase of citations of non-free articles. By using a dataset from the Social Science Research Network (SSRN), an open repository of research articles, and employing a natural experiment that allows the estimation of the value of free access separate from confounding factors such as early viewership and quality differential, this study identifies the causal effect of free access on the citation counts. The natural experiment in this study is that a select group of published articles is posted on SSRN at a time chosen by their authors’ affiliated organizations or SSRN, not by their authors. Using a difference-in-difference method and comparing the citation profiles of the articles before and after the posting time on SSRN against a group of control articles with similar characteristics, I stimated the effect of the SSRN posting on citation counts. The articles posted on SSRN receive more citations even prior to being posted on SSRN, suggesting that they are of higher quality. Their citation counts further increase after being posted, gaining an additional 10-20% of citations. This gain is likely to be caused by the free access that SSRN provides.”

Citations to Wikipedia in Chemistry Journals: A Preliminary Study

Posté le par

Wikipedia has been the subject of an increasing number of studies. Many of these have focused on the quality of Wikipedia articles and the use of Wikipedia by students. Little research has focused on the use of Wikipedia by scholars. This study helps to fill that gap by examining citations to Wikipedia in chemistry journals from three major publishers over a five year period.

The study reports the number of citations to Wikipedia and describes how Wikipedia is being cited. The results show that, while only a small percentage of all articles contained a citation to Wikipedia, it is in fact being cited as a credible information source in articles in major chemistry journals.
