Considering that the goal of social science research is to train and provide skilled and specialized human resources to carry out research, education, management and planning in various social and cultural fields, and also considering that the main emphasis of this field is the education and promotion of excavations. A field about the social issues of the country and the analysis and interpretation of their roots, contexts, causes and factors, description and analysis of their extent in the society and finally the analysis of the information obtained from these studies is to solve social issues, therefore providing considered solutions to deal with them. With these problems and social developments, it is necessary. Considering that one of the evaluation criteria of universities and countries is the quantity and quality of their research outputs in international reliable databases. The status of each country's indexed research outputs in international valid indexes indicates an important part of that country's scientific activities at the international level. Therefore, in order to analyze scientific activities, a clear picture of this situation has always been the focus of the country's research managers. Therefore, it is necessary to pay attention to the quality of research outputs in Iranian universities, which are considered the most important scientific hub of the country. The results of this research can be used for planning at the level of administrations, various vice-chancellors and the entire universities under review, and by knowing the priorities, abilities and weaknesses, provide the necessary facilities to make scientific activities more targeted in the subject areas of social and behavioral sciences in the universities under review.  Therefore, this research studies and analyzes the research outputs of Iran's major universities using qualitative Scientometrics indicators in the subject areas of social and behavioral sciences during the period of 2010-2020.

What is the status of the research outputs of Iran's major universities in the subject areas of social and behavioral sciences with a Scientometrics approach from the perspective of quantity and impact index based on Scopus database data during the years 2010 to 2020?

The review of the literature indicates that the quality of research outputs in Iran's major universities has been less studied over a long period of time and using multiple Scientometrics indicators. In most of the previous studies, only the average index and the percentage of documents were cited and the H index was used to study the quality level of research outputs. Therefore, according to the investigations carried out in the dimension of scientology and the need to pay attention to the quality of research outputs in addition to their quantity, the present article studies and analyzes the research outputs of major universities in Iran in the subject areas of social and behavioral sciences according to several indicators of effectiveness during the period of 2010-2020. In this way, it has helped to identify the scientific position of the universities in the subject areas of social and behavioral sciences, as well as planning for its development at the national level, and to help strengthen and improve the country's scientific rank at the international level.

The current research is of an applied type and has been carried out with a Scientometrics approach and with documentary and citation analysis methods. The community under review is all research outputs in the subject areas of social and behavioral sciences, including "subject areas of psychology, economics (economics, econometrics and finance)", "management (business, management and accounting)", "social sciences", and "sciences", decision-making", according to the subject classification of the Scopus database, in the major universities of Iran in the years 2010 to 2020. The research implementation environment was Scopus and Scival databases. Research data was collected from March 20 to March 28, 2019 from Scopus and Scival. The method of data collection is to refer directly and get standard outputs from Scopus and Scival databases. The indicators used in this research are: citations, average citations per article, H index, weighted citation impact at the field level, percentage of highly cited articles, and percentage of articles published in top journals. Descriptive statistics (with Microsoft Excel software) were used to analyze the data.

According to the results, the total number of research outputs in the subject areas of social and behavioral sciences of Iran's major universities in the target period was 19,582 records. In all the studied universities, the subject area of social sciences had the most research outputs. In general, the research outputs of Iran's major universities in the subject areas of social and behavioral sciences have been on the rise in the given period of time. The reason for this can be the increase of students and researchers in postgraduate studies. In terms of the number of citations index, Shahid Beheshti, Isfahan, Ferdowsi, Tabriz, and Shiraz universities have the most citations in the subject area of "social sciences" and in the universities of Tehran, Allameh Tabataba’i, and Tarbiat Modares, the subject area of "business, management and accounting" has the most citations. In most of the cases mentioned in the universities and subject areas under investigation that received the most citations, in terms of the index of highly cited articles at the threshold of 10% and the index of articles published in top journals at the threshold of 25%, they also took the highest percentages. This issue indicates the high quality of research outputs with more citations, which these findings are consistent with the vital and high research (2016) for this reason that the more the citations of the articles, the higher the quality. In terms of highly cited articles at the threshold of 10%, in the universities of Tehran, Tarbiat Modares, Isfahan, Ferdowsi, Tabriz, and Shiraz, the subject area of "Economics, Econometrics and Finance", and in Shahid Beheshti and Allameh Tabataba’i universities, the subject area of "Trade" "Management and accounting" got the highest percentages.

In terms of the index of articles published in top journals at the threshold of 25%, in Shahid Beheshti, Tehran, Tarbiat Modares, Ferdowsi, Tabriz universities, in the subject area of "Business, Management and Accounting", in Allameh Tabataba’i University, in the subject area of "Psychology", in universities Isfahan and Shiraz have the highest percentages in the subject area of "Social Sciences". In this regard, it has been mentioned in most of the cases that they have obtained a high percentage in terms of the index of highly cited articles at the threshold of 10% and the index of articles published in the top journals at the threshold of 25%. This issue shows the high quality of research outputs in the mentioned subject areas, which with the research of Irfan Manesh and Hosseini (2016), in terms of the impact of general impact indicators (H index, weighted citation impact index at the field level, citations) on the increase of articles published in Top journals and highly cited articles match. Since some of the indicators examined in this research, such as citations and the number of highly cited articles, are included in some ranking systems, such as the rankings of Leiden University, Saimgo University, and Shanghai University, increasing the mentioned indicators as much as possible is effective in improving the position of universities in these ranking systems.

In general, it is very important for universities to emphasize the quality of research outputs in addition to the quantity of these outputs. Attention to the quality of research outputs with the researches of Ebrahimi and Hayati (2007), Yaminifirouz et al. (2015) and Erfanmanesh and Hosseini (2018). Considering the number of received citations of the published research outputs of Iran's major universities in the review of their performance, as well as considering the special research credit and score for the authors of highly cited articles in various subject areas can be a suitable solution in this field. Also, emphasizing the quality along with the quantity of research outputs in universities and research centers should be given special attention.

We are grateful to Shahid Beheshti University Research Vice-Chancellor for their support in the implementation of this research.

The present research aims to identify the usefulness of the FWCI in evaluating the research activities of the researchers of the Agricultural Research, Education, and Extension Organization. In addition, the comparison of different subject fields of the organization in terms of the FWCI scores and also the comparison of the researchers' FWCI score of the organization with their H-index have been among other goals.

The current research was conducted with a scientometric approach and using the citation analysis method. The research community consists of 13,066 international articles from 1,589 researchers of the Agricultural Research, Education, and Extension Organization, whose data was extracted from the Scopus database and the Scientometric System of the organization. For the current research, only those researchers who simultaneously had an H-index of 1 and whose articles also had the FWC score (1589 people in total) were extracted from this collection and their data for this study. Were analyzed. The calculation of the average FWCI of the researchers was based solely on the articles with the mentioned score, and the articles without this score were excluded from the scope of the review. Data analysis was done using Excel and SPSS software.

The findings of the research show that in the investigated period, an average of 8 articles were published by each researcher, and these articles received a total of 206,175 citations. The average H-index of these researchers was 4 and their average FWCI score was 0.398. The highest score obtained in the FWCI index was 9.85. Researchers with the rank of professor and assistant professor have equally obtained an average of 0.46 in this index, and researchers with the rank of associated professor have also obtained a score of 0.42. The average of this index for all eleven subject groups is less than 1, and at the same time, the subject group of forest and pasture and natural resources with a score of 0.61 is higher than the other groups and the subject group of education is lower than the other groups with a score of 0.35. At the same time, the subject group of forest and pasture is ranked fourth in the H-index with an average of 4.07. The results also show that there is no direct relationship between the researchers' H-index and their FWCI scores as a whole, or such a relationship is very weak. According to the findings of the research, in some areas (such as agricultural biotechnology), a higher average H-index does not necessarily mean a higher quality of the articles, and the weighted subject average of these articles is at a lower level compared to their peers globally. On the contrary, in some areas such as soil protection, water, and watershed management, although it has a lower H-index average, it has far better conditions in terms of FWCI average score.

In total, the score of the organization's researchers in the FWCI is much lower than the global average, both in general and in terms of subject groups. In addition, despite the lack of wide differences between FWCI and H-indexes, using FWCI in evaluating the articles of the organization's researchers can be more reliable.

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.

Applying bibliometric indicators, this study tries to investigate the status of Persian knowledge management research based on the records in the Islamic World Science Citation Database (ISC) during the years 2008 to 2017.

This is a scientometric applied research. Bibliometric techniques and social network analysis are used in conducting this research. The research population consists of articles published in the field of knowledge management that have been indexed in ISC database during a 10-years period (2008-2017). BibExcel, UCInet, NetDraw and Vosviewer are among software that were used for analyzing data and drawing maps in this research.

The results showed a relatively steady growth in the number of knowledge management articles indexed in ISC between 2008 and 2017. “Akhavan P” is considered to be Iran's top researcher in the field of knowledge management in terms of the number of articles, citations and h-index. Also, based on co-authorship indicators, again “Akhavan P” owns the best position in the network. Moreover, results uncovered that 8 clusters are formed in knowledge management research.

Due to the diversity of authors from different disciplines among the articles as well as the variety of clusters resulting from co-word analysis, the present study confirms the theory that the field of knowledge management is an interdisciplinary one. Finally, based on integrative indicators, it can be stated that “Akhavan P” is the most influential researcher of Iran in knowledge management research during past 10 years.

The predictive power of researchers' productivity indicators in the Google Scholar has been investigated through metrics of the ResearchGate . This study is original in terms of objective and data gathering. The study adopted a descriptive method with webometrics approach. The population of this study consisted of authors of the most cited articles in the physics and space sciences field that were indexed in Scopus during 2005-2014. The authors were members of ResearchGate and had profiles in google scholar. The first 200 articles based on citation were selected as the sample. The data was analyzed using correlation and multiple regression. The results showed that download had a significant positive relation with H-index so that the regression model was significant. Download variable had the ability to predict researchers’ H-index. However, the regression model for i10 was not significant and none of the predictor variables had the ability to predict i10. Greater knowledge sharing by researchers through ResearchGate may increase the probability of visibility, hence an increase in download counts. Downloading and studying the scientific works of researchers can lead to the use of that work and thus increase productivity indicators of the researchers.

Considering the importance of scientific production in the ranking of universities and evaluation of faculty members as researchers who have most contribution in the scientific productions of universities, the present study examined the research performance of faculty members’ Bushehr University of Medical Sciences in Google Scholar in terms of quantity and quality. This research is descriptive survey was conducted using citation analysis. The study sample is scientific outputs of all faculty members working at Bushehr University of Medical Sciences in 2014 (including 160), which is indexed in Google Scholar. Data were collected using publish or perish, a citation analysis software. Data were analyzed using Microsoft Excel and descriptive indicators. Findings: The finding of this study showed that, 37/26% of the study population did not have any scientific Documents in Google Scholar and most of them (59/37%) had less than 20 Documents. Averaging 4/73 Documents for each of researcher was indexed in Google Scholar, and each person had received an average of 19/33 citation. The average number of citations per Document was also 1/83. Hirsch index average was equal to 1/45 and G-index was 1/2. Hirsch index and G-index were equal to zero for 48/12% of the study population. The present study indicates that the total number of documents, the total number of citations and Hirsh and G-index for the most researchers in this study are low. Low experience of the most researchers, language barriers and low international access to Persian documents are major reasons for this.

Nowadays, universities and higher education institutions have a critical role in developing countries and it is essential that their performance is evaluated with appropriate methods and criteria. Among the various functions of universities, research and scientific production is the most important one. The evaluation of scientific outputs is an attempt to assess the performance of universities. The use of scientometric indicators is a way to assess the scientific outputs of universities. In this context, a number of indicators have been defined to assess the quantity and quality of scientific outputs of researchers that can be extended to assess the institutions. Through a descriptive survey, in this paper, 285,526 scientific outputs of 76 universities affiliated to Ministry of Science, Research and Technology were selected and evaluated. The data of each university were analyzed individually using the indicators such as the number of scientific outputs, number of citations, h-index, m-parameter and g-index and the institutions were ranked. The results show that Tehran University in number of scientific outputs and number of citations, Sharif University of Technology in h-index and g-index, and Babol Noshirvani University of Technology in m-parameter are as the top Iranian Universities in the surveyed universities. The overall ranking shows that Tarbiat Modares University and Sharif University of Technology are top. Finally, we compare and discuss our ranking results with ISC and URAP ranking systems. The results show that the ranking of universities in this research in terms of the number of scientific outputs, the number of citations, h-index and g-index has a high correlation with that of ISC and URAP systems.

The aim of this study is to provide some criteria for reviewers in their process of evaluating the articles so as to help them predict future citations to these article based on their quality. This study deploys a descriptive - correlation and applied research. In this study, about 5 magazines as an example were selected among the Chemistry journals indexed in Scopus. Also among the 926 articles, 300 articles were examined stratified random sampling during the 2011 – 2015.The results indicated that "co-authorship" is the strongest predictor variable for predicting citation positively and significantly. Furthermore, variables of length of the article, number of references & H-index can also predict the citation Rate significantly. Along with the traditional criteria for evaluating article, the reviewers can also include other effective indicators in their evaluation process of articles, and, in turn, increase the visibility and citation rate of the articles. This makes it possible for the reviewers to deploy a reliable measuring tool for examining the quality of scholarly papers and predict the citation Rate.

The purpose of this paper is to explain how to use the h-index in the evaluation of research and researcher.
A qualitative research is conducted in which the statistical population includes the faculty members of universities and Iranian researcher in ISI and ISC. The sample consist of twenty faculty members in the University of Isfahan, Isfahan University of Technology, Isfahan University of Medical Science, Shahid Beheshti University of Medical Sciences and Health Services, Kharazmi University, Shahed University, Yasouj University and Razi University. In this study, purposive sampling is used. Data were collected through semi-structured interviews and analyzed based on the Grounded Theory.
Findings: Whit using of coding techniques in the Grounded Theory, seven categories are extracted and the H-index category is considered as the main issue. Other categories in this study are: strengths and weaknesses of the H-index, research ranking and promotion of researchers and universities, advocates and opponents of the H-index, and strategies to improve the H-index.
The results show that due to the numerous weaknesses of the H-index and considering that the h-index only reflects the scientific aspects of a person's activity (i.e. scientific outputs in the form of papers), therefore ranking and promotion of individuals, universities and etc. based on the H-index without having a complete knowledge about its negative consequences is not recommended
