Background and aim there are different indexes for evaluation of scientific outputs of scholars. This study aimed at evaluating and analyzing 9 cases of these indexes by using actual data and exploratory factor analysis.Material and methods: 40 citation reports of researchers was extracted from Web of Science (WoS) and entered into the checklist with the scientific age of researchers and the age of cited papers. Some descriptive and analytic statistics especially exploratory factor analysis were used by SPSS version 19.Findings: Exploratory factor analysis showed 3 factors with especial values and greater than 1 and with explained variance over 96% in 9 indexes. Factors 1, 2 and 3 explained 44.38%, 28.19%, and 23.48% of variance in correlation coefficient matrix, respectively. M index (with coefficient of 90%) in factor 1, a index (with coefficient of 91%) in factor 2, and h and h2 indexes (with coefficients of 93%) in factor 3 had the highest factor loadings. Correlation coefficients and related comparative diagrams indicated that the same h index among 9 indexes has been more accurate and different in recent years.Conclusions: As the studied supplemental indexes could not satisfied all limits of h index, scientific society needs a new index which accurately evaluates the quality besides the quantity of individual researchers' scientific outputs.

Background and aim: Various scientometric indicators have been developed for quantitative and qualitative evaluation of scientific output. Each of these indicators has its own weaknesses and strengths. The study aimed at using the keywords as a qualitative evaluation instrument in research of many scholars of Medical Sciences University.Material and methods: This study was conducted as a cross-sectional study within a 6-year period (2005-2010). The research population included all papers published by faculty members of Medical Science University of Babol who were as the first/corresponding authors with at least 2 papers and these indexed articles in periodicals published in WOS during this period. The data were collected by means of a tailor-made data collection sheet. The repeated or synonym keywords were collected from different papers of an author and were analyzed in terms of repetition for qualitative evaluation of the research of every scholar. The data were analyzed by using descriptive statistical indexes and statistical software spss version16.Findings: During this period, 127 articles have been indexed in WoS database from researchers of this University. in 11 articles of 300 words, 21 repeated words or synonyms were used by 25 researchers who had two or more than two papers. By considering these findings, the overall ratio of articles with repetitive keywords was 16% and the proportion of repeated keywords to whole words was 7%.Statistical processing of the data using linear regression indicates an inverse relationship between the number of articles of each author and repeated keywords or synonyms in his/her articles. So, by increasing the number of articles for every author from 2 to 5, the repeated words in per article were decreased to 0.83, 0.77, 0.25 and finally zero, respectively.Conclusion: low rate of the same keywords and synonyms in the articles of one researcher may be a sign of dispersion and lack of coordination in research activities. Therefore, regarding the coordination and concentration of the subject in scientific activities is very important in assessing the quality of research and researchers.

Background and aim: Present scientometrics study aimed at investigating the scientific collaboration of Iranian scientometrics researchers during 2002-2012.Material and methods: Using scientometrics approach, this paper studied co-authorship network of Iranian scientometrics researchers. The population includes 779 articles published both in English and Persian and indexed in 4th edition of scientometrics bibliography (last version till now) during 2002-2012. First, the co-authorship network matrix was drawn by using excel software; second, the UCINET software and VOS viewer were used for data analysis.Findings: The study of co-authorship patterns of Iranian scientometrics researchers indicated that Farideh Osareh (47 articles), Mohammad Hasanzadeh (43 articles), and Albdolrreza NouruziChackoli (36 articles) have the highest rank among scientometrics researchers in scientific productivity. According to central indicator, Farshid Danesh (77), Albdolrreza NouruziChackoli (69), and Mohammad Hasanzadeh (67) had the most number of co-authorship with other researchers.Conclusion: Although clustering coefficient (= 0.77) showed the relative interest of this network members to work with each other and shaping different clusters, the density coefficient (=0.009) revealed the low consistency of the network.

Background and aim: today, the measuring and monitoring of science in different fields and issues are considered in different centers and universities.This study aimed at determining the qualitative and quantitative growth of scientific production in the field of sport sciences.Material and methods: This research was a Scientometric study which analyzed the indexed scientific papers in Iran from 1994 to 17 March 2013 in the field of Sport Sciences by using qualitative and quantitative indices of (ISI) database. Data capture source, ISI base and 302 samples of recorded degrees in Iran were investigated in above years. The data were analyzed by Excel software.Findings: Results showed that the Iranian researchers published 302 degrees in this base from 1994 to 17 March 2013, which were referable in 1515 cases up to now and the h index in this scientific field was estimated 20. Scientific papers in the field of sport sciences have had the growth process since 2007. The highest scientific production has been in Tehran University of Medical Sciences with indexed degrees, Islamic Azad University of Tehran University with 42 degrees and 28 degrees, respectively.Conclusions: Given the number of professors, researchers and students We can say that scientific publications in the field of sports science In terms of quantitative (302 document) is not optimal But according to the h index is said to be optimal in terms of quality.

Background and aim: with rapid innovations and advancements in information and communication technologies in this era, the status of journals of Islamic Republic of Iran and the efforts to improve the quality and quantity of Iranian journals in international level are very important. The present research intends to assess indexed Iranian journals in Scopus database quantitatively and qualitatively.Material and methods: the present research is a descriptive survey which can be applied through Scientometrics methods. Scopus database is the data source here. This research community comprises all Iranian scientific journals indexed in Scopus database during 2000-2012. Statistical software Excel was used to analyze the data and network analysis software NodeXL was applied to draw shapes.Findings: findings indicate that an increase in the number of indexed Iranian Journals in Scopus database from 8 titles in 2000 has reached to 113 titles in 2012. These findings also show that more academic-scientific institutes and centers have been in charge of managing and indexing scientific journals during the study years.Conclusion: unlike the quantitative growth in the number of indexed Journals, the quality of indexed Iranian journals (except for few cases) does not have a desirable condition. Thus, the policies on this issue can be helpful in this regard.

Background and aim: doctors considerably use evidence-based medicine in order to answer their clinical questions and support clinical decisions. The aim of this paper was to determine the compliance rate of evidence-based medicine resources with Ovid and Silberg criteria.Material and methods: This study is an applied research, which was carried through survey and webometric methods. The samples were consisted of six evidence-based medicine resources. Evaluations were done by using Silberg and Ovid Criteria. The collected data was analyzed in SPSS (version 20) by using descriptive statistics (frequency and frequency percentage) and analytic (Spearman's test).Findings: Findings showed that databases complied with Silberg criterion at a level of 88.88% with a total score of 48 out of 54 and complied with Ovid criterion at a level of 36.92% with a total score of 319 out of 864. This indicated that the position of databases in Silberg criterion was more than half of the total score, but in Ovid criterion, it was less than half of the total score. Results also showed that there was no correlation between compliance rate of evidence-based medicine with Ovid and Silberg criteria.Conclusion: Although evidence-based medicine resources have been validated according to Silberg criterion, components such as user interface, usability, and technical issues have not been considered in their design.

Background and aim: Due to the limited financial and human resources, determining the research priorities are the most important issues facing science and technology policymakers. This study determined the Iranian research priorities from economic approach.Material and methods: This study is applied research with scientometrics and econometrics methods. Science production data were extracted from SCImago and Gross Domestic Product Per capita (GDPP) data were extracted from World Bank database and data were analyzed by EViews 7 software.Findings: Engineering and Human Science groups (0.01 level) have affected GDPP. Human science (0.01 level), Medicine and Veterinary (0.05 level) groups have been affected by GDPP.Conclusion: Biomedical Engineering, Building and Construction, Control and Systems Engineering, Industrial and Manufacturing Engineering, Mechanical Engineering, Material Science, and the Mechanics of Material fields have affected economic growth. In other words, these fields can be placed in Iranian research proprieties.
