 Editorial Board Metrics (EBM) is used to determine the performance, effectiveness, and role of editorial board members and journal editors in policymaking and designing a roadmap for the future of journals. This study analyzed and evaluated indexed journals in health sciences, biological sciences, arts, and humanities using EBM.

 Social Network Analysis (SNA) was used to visualize the interconnections of editorial board members and journals. For this purpose, centrality indices were used, including degree centrality, closeness centrality, and betweenness centrality. Data analysis was performed in two descriptive and inferential sections for editorial board members (2813 individuals) and journals (200 journals) using statistical methods such as frequency, percentage, mean, Kendall's Tau-b coefficient, Chi-square test, and software such as UCINET, SPSS, Net Draw, and Python.

 The research findings on the status of the impact factor of journals indicate that in the field of humanities and arts, the "Journal of Applied Issues in Islamic Education" with 1.095 has the highest impact factor. In the field of health sciences, "Iranian Journal of Ageing (Salmand)- Waiting List" with 0.446 has the highest impact factor, and in the field of biological sciences, "Plant Genetic Researches - Primary List" with 0.37 has the highest impact factor in each subject area. Some journals in the fields of humanities and arts have a high self-citation rate, including journals that have over 80% self-citation in the field of humanities and arts, such as "The Journal of Nahjolbalagheh" (77.80%) and "Journal of Kurdish Literature" and "Persian Language and Iranian Dialects" (100%). Ahad Faramarz Gharamaleki (Professor at the University of Tehran) and Mohammad Hassan Ghadrdan Gharamaleki (Professor at the Institute of Culture and Islamic Thought) have the highest level of interlocking (frequency 5). Of 368 individuals with co-authorship, 333 are male, and 35 are female. Regarding academic rank, the "Professor" with 71.76% and "the Associate Professor" with 15.48% have the highest share in the editorial board community.

 Of the 2,813 individuals who collaborated in 200 journals, 368 editorial board members had to interlock. The results indicate a significant negative relationship between the impact factor and the interlocking of the social science research journals and between the number of citations received by journals and their interlocking. Furthermore, there is a correlation between a rise in journal quartiles and a decrease in interlocking. According to the results, the number of journal quartiles is a significant negative predictor of interlocking. The Immediacy Index (II) of journals, the Median Impact Factor (MIF) in the macro subject, the number of articles, and the self-citation index are not significant predictors of interlocking. Considering the role of editorial board members in the development and quality improvement of journals through reviewing and selecting topics, the effort to form more diverse editorial boards with less interlocking will not only bring more diverse research output to the publishing world, deposit; which will create a positive competitive environment with a broader range of votes.

Periodical publications are one of the resources through which users reach the scientific publications and scientific productions from different groups of researchers. Among documents and publication resources, the periodical publications are considered the most important resources for scientific information due to their speed of publishing and the effective role they play in the transmission of information. The level of production and quality of publications are among the indicators of the scientific and cultural growth in any society (Fat'habadi, Kamari and Sharifi, 2015). Publications play a role in continuous education and improvement in research and distribution of scientific activities (Sieger, 2003). The European Union Commission has confirmed this and believes that scientific publications have a dual role in the validation and dissemination and this is important in archiving knowledge and to guarantee permanent access to it (European Commission, 2006). To value scientific publications equals their continuous assessment, taking care production of knowledge and science; and dissemination and sharing of that knowledge. Nowadays, scientometrics has been defined as a method to measure science, which defines the achievements of an intellectual realm and even predicts possible lines for further progress through examination and discovery of system and structure of science field by using quantitative means. One could assess the distribution of frequency as well as the evaluation of scientific entities such as publications through the application of the techniques and laws available in Scientometrics. The purpose of this study was to investigate the relationship between citation indices and classification of publications in the field of infertility through Bradford method.

This descriptive correlation study was done by Scientometrics survey. The sources of data collection were all ranking reports of infertility journals from Thomson Reuters (JCR) and Scopus (SCImago) in the period 2014-2012.  Infertility journals in the PubMed database form the research community. In order to collect data in the first stage, the list of indexed journals in the field of infertility was extracted from the PubMed database. The indexing of journals in PubMed database was reviewed through the website of the National Library of Medicine of America. In this study, Bradford Law was applied to include a number of proper journals. As a result, 92 journals were selected according to Bradford Law: the first category (4 journals), the second category (16 journals), and the third category (72 journals). Then, the values of STR, H- index, from the SCImago and impact factor from the JCR database were extracted. The extracted values were taken as the basis for analyzing and studying the relationship between the indices. Excel and SPSS software were used to analyze the data while Pearson correlation test and linear regression were used due to the quantitative nature of research variables.

The results of the fitting distribution of specialized journals in the field of infertility according to Bradford Law showed that the number of publications of each category has increased with a constant coefficient compared with its previous category. This constant coefficient indicates that the distribution of journals in these three categories is consistent with the distribution of Bradford. According to the research findings, the impact factor, SJR with H- index of infertility journals is positively correlated with Bradford's frequent distribution of these journals.

In general, according to the results of this study, the selection of publications with each of the evaluations of the SCImago and JCR and the law Bradford in the field of infertility is possible due to the correlation between them, although there was a very little difference between this correlation from the publications of the first category to all journals. Given the disadvantages of the impact factor, as well as the differing rankings of the journals and the number of indexed publications in the bases, along with other studies; these indicators can be a good benchmark for top journals. Along with the present study, Myers and Young (2017) showed that neither of the indicators of evaluation of the journals are superior to each other, but indicators such as the H index are more effective in evaluation of management and business journals. In general, the present study, along with other studies, confirmed the features of empirical rules (in the present study, Bradford) such as categorization and generalization (Tavakolizadeh and Soheili, 2015).   According to the results, researchers and authors of infertility field can use the impact factor, SJR, Bradford law and H- Index to select appropriate journals in their specialized field. It is also proposed to do similar research on the relationship between indices in other journals and the comparative evaluation of other citation metrics of journals at different fields.

Due to medical researchers need for updated and valid scientific findings in their research area, it is important to evaluate medical journals. On the other hand, researchers are looking for prestigious journals to publish their articles in their field of activity. Because much of the medical journals in Iran published by Universities of Medical Sciences, this study aimed to evaluate Iranian Medical Sciences Universitie's research journals in Google Scholar citation database between 2010-2014, with emphasis on both scientific impacts: The Journal Hirsch index and Journal Impact factor. In order to collect data the researchers used publish or perish, which is a citation analysis software. Data were analyzed by descriptive statistics and Spearman correlation test using Microsoft Excel and SPSS16. The results showed that a total of 38,717 articles from 130 surveyed journals in the period of study was indexed in Google Scholar and these articles had received 61,938 citations, i.e. 1.6 citations per article. Total average of Hirsch index in study population was 7 and total average of journals impact factor was 1.31. Spearman correlation test results showed that the journal language and number of journals articles have a significant positive correlation with the number of received citations, journal Hirsch index and journal impact factor. The relationship between journal impact factor and Hirsch index was significant too. It seems that due to the high correlation between journal impact factor and Hirsch index, these two indicators can be used as complementary elements in evaluating journals.
