BACKGROUND There is a dire need in the Arab world and Middle Eastern countries to reform the higher education, research policy and planning for improving the quality to meet the needs of modern society. The impact factor (IF) was developed in the 1960s by Eugene Garfield of the Institute for Scientific Information (ISI) in the USA. It has been extensively used for more than 40 years. The SCImag...

Despite its widespread acceptance in the scientific world, impact factor (IF) has been criticized recently on many accounts: including lack of quality assessment of the citations, influence of self citation, English language bias, etc. In the current study, we evaluated three indices of journal scientific impact: (IF), Eigenfactor Score (ES), and SCImago Journal rank indicator (SJR) of nuclear ...

Subject classification arises as an important topic for bibliometrics and scientometrics as to develop reliable and consistent tools and outputs. For this matter, a well delimited underlying subject classification scheme reflecting science fields becomes essential. Within the broad ensemble of classification techniques clustering analysis is one of the most successful. Two clustering algorithms...

The purpose of this study is to explore the metrics comparison between Impact Factor (IF) and SCImago Journal Rank (SJR) for journals indexed in both Web of Science (WoS) and Scopus databases. The study analyses five engineering education journals and seven educational technology journals, which are indexed in both WoS and Scopus. The analysis dates are limited to 2010 through 2011. The results...

Introduction: In the current study, we compared h5-index provided by Google Scholar (GS), impact factor (IF) provided by web of sciences (WOS), and SCImago journal rank indicator (SJR) provided by SCOPUS for quality assessment of nuclear medicine journals. Methods: 2013 h5-index, 2012 IF, and 2011 SJR of nuclear medicine journals were extracted from their publishers namely GS, WOS, and SCOPUS. ...

Objectives: Our research seeks to examine the correlation between the presence of physical medicine and rehabilitation journals in social networks and the SJR impact factor. Methods: We carried out a correlation study. For the research, we took into account all physical medicine and rehabilitation journals included in the SCImago Journal Rank. The number of followers on Twitter, Facebook, YouT...

W hen the multinational media and information company Thomson Reuters recently announced—somewhat later than usual—the Journal Citation Reports (JCR) for 2013, the impact factor of 1.427 represented a 38% increase for Diagnostic and Interventional Radiology, up from 1.031 for 2012 (Table 1) (1). This is a truly impressive yearly increase by any standard and the journal’s current Editor-in-Chief...

81 Editorial I welcome you to this second issue for the year 2011 comprising very interesting articles to read. We are proud to inform about the inclusion of our journal in SCImago Journal Ranking [SJR] recently. SJR is one of the two major journal rating systems that exist in the world: the Journal of (Madrid) and Alcalá de Henares). It is named after the SCImago Journal Rank Indicator (SJR) d...
