Scholars on Twitter: who and how many are they?

Posté le par

Authors :  Rodrigo Costas, Jeroen van Honk, Thomas Franssen

In this paper we present a novel methodology for identifying scholars with a Twitter account. By combining bibliometric data from Web of Science and Twitter users identified by Altmetric.com we have obtained the largest set of individual scholars matched with Twitter users made so far.

Our methodology consists of a combination of matching algorithms, considering different linguistic elements of both author names and Twitter names; followed by a rule-based scoring system that weights the common occurrence of several elements related with the names, individual elements and activities of both Twitter users and scholars matched.

Our results indicate that about 2% of the overall population of scholars in the Web of Science is active on Twitter. By domain we find a strong presence of researchers from the Social Sciences and the Humanities. Natural Sciences is the domain with the lowest level of scholars on Twitter.

Researchers on Twitter also tend to be younger than those that are not on Twitter. As this is a bibliometric-based approach, it is important to highlight the reliance of the method on the number of publications produced and tweeted by the scholars, thus the share of scholars on Twitter ranges between 1% and 5% depending on their level of productivity. Further research is suggested in order to improve and expand the methodology.

Determining how scientific achievements influence the subsequent process of knowledge creation is a fundamental step in order to build a unified ecosystem for studying the dynamics of innovation and competitiveness.

Yet, relying separately on data about scientific production on one side, through bibliometric indicators, and about technological advancements on the other side, through patents statistics, gives only a limited insight on the key interplay between science and technology which, as a matter of fact, move forward together within the innovation space.

In this paper, using citation data of both scientific papers and patents, we quantify the direct impact of the scientific outputs of nations on further advancements in science and on the introduction of new technologies.

Our analysis highlights the presence of geo-cultural clusters of nations with similar innovation system features, and unveils the heterogeneous coupled dynamics of scientific and technological success.

This study represents a first step in the buildup of a comprehensive framework for knowledge creation and innovation.

Relationships between Consumption, Publication and Impact in French Universities in a value perspective: A Bibliometric Analysis

Posté le par

Authors : Chérifa Boukacem-Zeghmouri, Pascal Bador, Thierry Lafouge, Hélène Prost

The study aims to investigate the relationships between consumption of e-journals distributed by Elsevier ScienceDirect platform, publication (articles) and impact (citations) in a sample of 13 French universities, from 2003 to 2009.

It adopts a value perspective as it questions whether or not publication activity and impact are some kind of return led by consumption. A bibliometric approach was used to explore the relations between these three variables.

The analysis developed indicators inspired by the mathematical h-Index technique. Results show that the relation between consumption, publication and citations depends on the discipline’s profile, the intensity of research and the size of each institution.

Moreover, although relations have been observed between the three variables, it is not possible to determine which variable comes first to explain the phenomena. The study concludes by showing strong correlations, which nevertheless do not lead to clear causal relations.

The article provide practical implication for academic library managers who want to show the added value of their electronic e-journals collections can replicate the study approach. Also for policy makers who want to take into account e-journals usage as an informative tool to predict the importance of publication activity.

Originality: The study is the first French contribution to e-journal value studies. Its originality consists in developing a value viewpoint that relies on a bibliometric approach.

Open-Access Mega-Journals: A Bibliometric Profile

Posté le par

Authors : Simon Wakeling, Peter Willett, Claire Creaser, Jenny Fry, Stephen Pinfield, Valérie Spezi

In this paper we present the first comprehensive bibliometric analysis of eleven open-access mega-journals (OAMJs).

OAMJs are a relatively recent phenomenon, and have been characterised as having four key characteristics: large size; broad disciplinary scope; a Gold-OA business model; and a peer-review policy that seeks to determine only the scientific soundness of the research rather than evaluate the novelty or significance of the work. Our investigation focuses on four key modes of analysis: journal outputs (the number of articles published and changes in output over time); OAMJ author characteristics (nationalities and institutional affiliations); subject areas (the disciplinary scope of OAMJs, and variations in sub-disciplinary output); and citation profiles (the citation distributions of each OAMJ, and the impact of citing journals).

We found that while the total output of the eleven mega-journals grew by 14.9% between 2014 and 2015, this growth is largely attributable to the increased output of Scientific Reports and Medicine.

We also found substantial variation in the geographical distribution of authors. Several journals have a relatively high proportion of Chinese authors, and we suggest this may be linked to these journals’ high Journal Impact Factors (JIFs).

The mega-journals were also found to vary in subject scope, with several journals publishing disproportionately high numbers of articles in certain sub-disciplines.

Our citation analsysis offers support for Björk & Catani’s suggestion that OAMJs’s citation distributions can be similar to those of traditional journals, while noting considerable variation in citation rates across the eleven titles.

We conclude that while the OAMJ term is useful as a means of grouping journals which share a set of key characteristics, there is no such thing as a “typical” mega-journal, and we suggest several areas for additional research that might help us better understand the current and future role of OAMJs in scholarly communication.

Bibliometric and benchmark analysis of gold open access in Spain: big output and little impact

Posté le par

This bibliometric study analyzes the research output produced by Spain during the 2005-2014 time period in Open Access (OA) journals indexed in Web of Science. The aim of the paper is to determine if papers published in Open Access journals contribute to the improvement of citation impact and collaboration indicators in Spanish research.

The results are shown by scientific areas and compared with 17 European countries. Spain is the second highest ranking European country with gold OA publication output and the fourth highest in Open Access output (9%). In Spain OA output is especially high in the fields of Arts and Humanities (28%). Spain’s normalized citation impact in Open access (0.72) is lower than the world average and that of the main European countries. Finally, we discuss how these results differ from the so-called Open Access citation advantage.

Impact of assessment criteria on publication behaviour: the case of communication research in Spain

Statut

“Introduction: This paper outlines the evolution of Spanish production in the area of communication research over the last seventeen years. It analyses whether the consolidation of the existing systems of assessment of scientific activity have been mirrored by an increase in the output of Spanish authors in journals indexed by the Social Sciences Citation Index.

Method:  A bibliometric approach to the subject matter has been selected.  We have analysed indicators such as institutional and individual productivity, models of publishing and dynamics of co-operation (intra-and inter-institutional, national and international).

Analysis: This method has been applied to thirty-four journals included in the communication category of the Social Sciences Citation Index. To ensure consistency in the data collected, only journals that have remained in this database over the seventeen years covered by the research, from 1994 to 2010, have been selected.

Results: Results reveal that the output of Spanish researchers in communication has increased significantly over five years, from forty-eight papers in 1994-2005, to eighty-two for the period 2006-2010.

Conclusions: The increase coincides with the creation in 2002 of National Quality and Accreditation Evaluation Agency (ANECA) whose assessment criteria give priority to publication in journals indexed by the Social Sciences Citation Index.”
