Dental research in Iran: a bibliometric analysis of electronically available literature

Purpose : To carry out a bibliometric analysis of all electronically available dental literature in Iran from 1983 to 2006, in order to study availability and examine trends. Materials and Methods : Accessing all electronically available Iranian dental articles published in domestic journals, and comparing the results with Iranian dental articles published in Pubmed. The following data were collected from each article: name of journal, year of publication, number of authors, gender of corresponding author, academic levels of authors, main language of article, language of abstract, study environment, population studied, field of dentistry, type of article, design strategy, design of study, and analysis design. Results : In terms of publications in domestic journals, a total of 1,994 dental articles were electronically available, published in six different dental journals in Iran. Majority of articles, 84.5%, were original studies. In terms of design strategy, 49.7% of studies were cross‐sectional, 35.5% were prospective, and 14.8% were retrospective studies. The main language of 99.3% of articles was Farsi, and 0.7% was English. Majority of articles, 38.7%, were written by two authors. Gender of corresponding author in 66.7% of articles was male, and in 33.3% of articles was female. There was an increasing trend in percentage of original studies, clinical trials and female corresponding authors. In terms of publications in Pubmed, a total of 75 dental articles from Iran were electronically available. Significant differences were revealed in terms of number of authors, study types and design strategies when compared to publications in domestic journals. Conclusion : A number of encouraging trends were identified, which is a reflection of improvements in quality of domestic electronic dental literature. However, as the majority of articles are written in Farsi, availability of research evidence to the international community is limited. Overall, results of this study indicate the need for future bibliometric analyses which can be used to construct a comprehensive database that will assist in evidence‐based clinical decision making.

合理设置期刊出版周期与载文量的理性思考

【目的】 对《广东农业科学》“缩短出版周期—增加载文量—提升期刊影响”的办刊实践挫折进行反思,为科技期刊变更期刊出版周期、合理设置载文量提供参考。【方法】 选取《广东农业科学》与部分国内综合性农业科学类优秀期刊(《中国农业科学》《干旱地区农业研究》《华北农学报》《华南农业大学学报》和《南方农业学报》)为研究对象,实证分析出版周期及载文量对期刊的影响。【结果】 在稿源质量有保障的情况下,缩短刊期,适当增加载文量,对提升期刊传播力和影响力有积极作用。【结论】 当前“压缩载文量—做小分母—提高期刊影响因子”的现象非常普遍,但减少载文量不一定能提升期刊影响力,建议将载文量重新纳入科技期刊评价体系,以抑制过度压缩载文量的不良现象,积极推动科技期刊的繁荣发展和科研成果的及时传播;结合在线优先出版、网络首发等渠道,进一步缩短论文发表时滞,可确保学术成果的首发权与快速传播,有效提高期刊的传播力和学术影响力。     

Bibliometric analysis of Nobelists’ awards and landmark papers in physiology or medicine during 1983–2012

Abstract

Aim. This study's purpose was to determine if there was a relationship between Nobel Laureates’ awards and landmark papers and winning the Nobel Prize in Physiology or Medicine during 1983–2012.

Methods. The 66 Nobelists’ awards and landmark papers in the period 1983–2012 were analyzed.

Results. The results showed that the most Nobelists had won Gairdner, Lasker, Howitz or Wolf Award before they won Nobel Prize, indicating that Gairdner Award may be considered as a Nobel Prize’s wind vane. A small number of landmark papers were indeed published in low impact factor journals (10.5% below impact factor 5.0) and some of their citation were low (23.2% below 400 times). There were 61 of 76 landmark papers published in the journals of JCR partition 1, reaching 80%, but 2 of 76 landmark papers were even outside of JCR partition, demonstrating that JCR partition acts as a reciprocal supplement with impact factor and citation times. The test period of Nobel Prize was substantially between 10 to 30 years. There were 5 persons whose landmark papers were cited all above 6000 times to get Nobel Prize within the test period of ten years, suggesting that there is a trend of certain inverse ratio between the citation and the test period of Nobel Prize.

Conclusion. These findings provide a new insight into the relationship among Nobel Laureates’ awards, landmark papers and Nobel Prize in Physiology or Medicine.
