ABSTRACT
Introduction: Co-authorship network is a kind of social network that presents significant information about collaboration among authors, which is one of the most important factors of the qualitative and quantitative growth of the scientific publication. Regarding the fact that during 2000-2012, Pharmacy and Pharmacology has had the most number of publications in WoS among institutions belonging to the Ministry of Health and Medical Education [MHME], in this research, the co-authorship network of this field is investigated and analyzed. The results of this study can clarify the dimensions of collaboration in the field and help research policy as well
Method: The present study was conducted through scientometric method and social network analysis. The data were drawn from the WoS, downloaded in June 2013, and analyzed by PAJEK software. The research population included 3514 Pharmacy and Pharmacology documents published by universities affiliated to the MHME during 2012-2000
Result: The results of the study showed that the majority of collaborations of the Iranian researchers have been from England, USA and Canada, respectively. Co-authorship network of researchers consisted of 90 nodes [authors] and density degree of the network is 0.084. There is a strong linear correlation between the number of publications and degree centrality of authors at the 1 % level
Conclusion: The degree density of the network under study [.084] shows that this network has a low density. In fact, authors [nodes] in the network have had few relations with each other. This research also revealed that researchers with more publications are likely to have more collaborative works
ABSTRACT
Statement of Problem: Science production in medical fields such as dentistry is of great significance. Science production can be appropriately directed through recognition of the most effective investigations, the most active institutions and countries in science production domain and also determining the status of specialists
Purpose: The aim of this survey was to study the rate of dental science production indexed in the Web of Science [WOS] database by Iranian and other countries' specialists
Materials and Method: Using Web of Science, science production in dentistry in 2000-2009 was estimated; revealing 5005 records for scientists around the world and 32 for Iranian specialists. Then, analyses were done using HistCite software
Results: The findings showed that the growth rate of scientific production in dentistry was 64.53% in 2000-2009. USA was in the first rank among other countries; British Dental Journal, Sao Paolo University, and Kokich Vare were the top journal, institution and author, respectively
Data related to Iran showed that Tehran and Shiraz Universities were the first and second top institutions, each with 6 articles. M.H.Fathi with 44 TGCS was the most prolific author in WOS and H.R.Pakshir with 4 TLCS was the most highly published author in WOS in this collection
Conclusion: The findings showed that USA and UK were the first and second top countries in this regard. Iran had only 0.63% of the scientific production of dentistry in the Web of Science database, which is considered low in spite of the importance of this field
