Sj Ghazimirsaied, M Hemmat, H Dargahi, J Khansari,
Volume 4, Issue 3 (3-2011)
Abstract

Background and Aim: Using Hirsch index as an important tool to describe the scientific outputs of researchers has caused some authors to increase their self-imposed parameters, increase, citing themselves. Therefore it is necessary to consider the effect of self-citation on Hirsch index for every author to have better measuring on the quality of researchers scientific production.

Materials and Methods: This research is descriptive method of citation analysis in general and specifically self-citation analysis. The study, are Iranian prolific authors in the field of medicine that have at least 30 documents indexed in Web of Science database between 2004 to 2006. Citations following up was studied till December 2010 Results was analysis using Excel software version 2007.

Results: The average self-citation observed between prolific authors in medical field was 25/89 percent. Hirsch index for 30/77 percent of authors had changed considerably. The authors rating scheme based on Hirsch index was done after removing self - citation so that 38/46 percent of authors decreased to lower level.

Conclusion: Considering that 10 to 30 percent of self-citation can be normal and justified, the status of self-citatin of Iranian prolific authors in medical field is desirable. Also, lower rates of self - citation of these authors doesnot affect Hirsch index.

Volume 8, Issue 1 (5-2014)
Abstract

 Background and Aim: Scientific journals are the most major tools in disseminating research findings. With the increasing number and price of scientific journals, libraries need to select journals. Citation analysis is a practical method in identifying the best titles to be subscribed. This study was to identify core journals in the field of dentistry using citation analysis.

 Materials and Methods: Two hundered and seventy six documents including dentistry theses (241 titles) and faculty papers (35 titles) indexed in Science Citation Index (SCIE) were selected and their references were extracted and evaluated using citation analysis methods. The distribution frequency of journals confirmed the Bradford’s Law of Scattering representing core dentistry journals.

 Results: Eleven thousand twenty three references were totally extracted. Average reference per theses and papers was 39/25 and 44/74, respectively. English journals and books were the most frequent referred documents having 95% of total references approximately. The most updated references were in English dated during 2001-2005 and 2006-2010. Using the Bradford’s Law, five journals were introduced as core dentistry journals.

 Conclusion: Selecting and subscribing core journals leads into cost-effectiveness in libraries and plays an important role in meeting user’s needs. While having many challenges in accessing scientific resources, core journals selection and subscription is an intelligent action resulting in effective use of financial resources.

Soheila Khoeini, Ali Reza Noruzi, Zeinab Jozi, Esmaeil Mostafavi,
Volume 15, Issue 6 (3-2022)
Abstract
Background and Aim: Bibliotherapy is a useful treatment for the prevention and treatment of mental disorders and has led to the formation of many scientific publications in this field. The purpose of this study was to investigate the publication trends in the field of bibliotherapy and visualize the structure of its scientific collaborations based on the Web of Science database during the period 1975 to 2020.
Materials and Methods: The present scientometric study was conducted by citation analysis and social network analysis. The statistical population includes 1032 documents published. HistCite, VOSveiwer, Pajek and UciNet software were used to analyze the data. The co-authorship networks were analyzed and drawn by the VOSviewer software.
Results: U.S., UK, and Australia were ranked first to third with 369, 148, and 91 documents respectively. The documents published by researchers from these three countries have received 10547, 3459, and 3041 citations, respectively. The Universities of Alabama, Nevada, and the Karolinska Institutet in Sweden published the most in this field, with 29, 26, and 21 documents. Scogin F, Cuijpers P, and Rohde P were the most prolific authors with 29, 21, and 17 documents, respectively. Miller WR, Cuijpers P, and Andersson G received the most citations with 2441, 2298, and 1750, citations respectively. UK with 63 degree centrality, U.S. the most influential country with a betweenness centrality of 191.450 and the closeness centrality of the 80 were the most influential countries, and Vrije Universiteit Amsterdam with a betweenness centrality of 1416.755 and a closeness centrality of 658 and the Karolinska Institute with a degree centrality of 43 was the most influential organizations. Rohde P with 39-degree centrality and Cuijpers P with 314.500 betweenness centrality and 821 closeness centrality were the most active author in the co-authorship networks in bibliotherapy. Journal of Clinical Counseling and Psychology was the most cited and the Journal of Poetry Therapy published the most documents.
Conclusion: Paying more attention than before to the cooperation of countries, universities and active authors in the field of bibliotherapy can lead to more knowledge and experience exchange in developed and developing countries.

Shima Moradi, Fatemeh Rezaei Zadeh, Monireh Rahimkhani,
Volume 17, Issue 4 (10-2023)
Abstract
Background and aim: This study aimed to determine the position of Iran in terms of scientific publications in Immunology and Microbiology, and also to identify the general status of science production and the patterns of publishing in the world, the Middle East, and Iran, analyze Iran scientific collaboration with the Middle East and the world, and explore the relationship between these indicators.
Materials and Methods: The study population contained 30622 Middle Eastern publications in Immunology and Microbiology from 2009 to 2018. Positioning the countries and exploring the relations of indicators, the exploratory factor analysis, and the correlation matrix were conducted using Scival.
Results: According to the findings Iran, Turkey, and Saudi Arabia were among the most powerful countries in the region in terms of publication, citation, regional, international, and overall scientific collaboration. As for regional positioning, the citations had the highest weight comparing to other indicators. Iran have the first rank in the indices of scientific production and citations with 43.63% and 33.76% respectively, third rank in the regional cooperation index with 43.63%, second rank in the extra-regional cooperation index with 23.56%, and also second rank in the total cooperation index with 22.12%.
Conclusion: The indicators were strongly connected togather; however, the citations and international scientific collaborations displayed the strongest amongst others. Despite Iran’s prominent position in both fields, the quality of the publication was lower than the regional and global average. This identified the most powerful and weak countries in the region in regards to scientific capacities in Immunology and Microbiology. Moreover, it reckoned that there was a strong relation between citations and scientific production in contrast with others.
