A Study of Relationship between the Co-Authorship and Impact Factor in Persian Technical and Engineering Journals of Iran during 2001-2010
Abstract
Purpose: The aim of this research is to study the relationship between the co-authorship and the impact factor in Persian technical and engineering journals of Iran during the years 2001-2010. Method: The research method is analytic-descriptive with a citation analysis approach. The research population consists of 9321 papers from 77 Persian technical and engineering journals of Iran during the years 2001-2010. The data analysis was performed through Excel® and SPSS® v.20 programs. They were analyzed by statistics methods like, ANOVA, Chi Square, and Regression analysis. Findings: Findings showed that the average number of authors for Persian technical and engineering journals’ papers of Iran was not experienced a considerable change in the period mentioned above. The co-authorship was a dominant status in the papers that were studied but the average number of authors was slowly increases during the years of study. The findings also showed that a relationship is occurring between the co-authorship and Journal Impact Factor from 2010. Conclusions: The findings suggested that the co-authorship trend was unchanged during the studied period and the trend towards writing articles with two or three authors has been more significant. Occurring a significant relationship between the number of authors and the Impact Factor at the end of the studied period gives a positive outlook for the role of co-authorship in receiving more citations in future. As a final conclusion, the role of the number of authors in rising the chance for receiving more citations has been 17 percent among the other factors in Iranian technical and engineering journals.
