ABSTRACT
Objective To analyze the inherent quality of non-cited papers published in Chinese Journal of Endemiology, so as to identify the direction of invitation for contributions, and to provide the evidence for improving the academic quality and the cited rates. Methods Scientific papers published in Chinese Journal of Endemiology from 2004 to 2006, with zero cited rates were retrieved in China National Knowledge Infrastructure by March 24, 2011. These articles were statistically analyzed according to publication year, section type, download frequency, etc. Results A total of 200 papers were not cited, accounting for 23.04% (200/868) of the total number of papers published in the journal in the three years. Respectively, 17.23% (46/267), 24.39% (70/287)and 26.75% (84/314) of the papers published in 2004, 2005 and 2006 did not receive a single citation. The number of non-cited papers in editorial and expert forum column was zero, all articles in those column had been cited;followed by review column, non-cited rate was 6.98% (3/43);articles published in the column of short reports were seldom cited and non-cited rate was the highest of 54.02%( 121/224);all the columns of experimental study, field epidemiological investigation, clinical medicine, detection method and sanitary control had a certain percentage of non-cited papers. All of the 200 non-cited papers were downloaded, the download frequency ranged from 1 to 109, with an average of 27.21 times. Conclusions Adequate space should be given to the columns of editorial, expert forums, review, experimental study and field epidemiological investigation;the number of short reports should be reduced appropriately. The journal should enhance cited rate of published papers, comprehensively improve the academic quality of the articles, and contribute to the academic exchange and discipline development.
ABSTRACT
Objective To analysis the inherent quality of highly cited papers published in Chinese Journal of Endemiology, so as to identify the direction of invitation for contributions, find high quality articles, and to improve the journal's core competitiveness. Methods Scientific papers published in Chinese Journal of Endemiology from 2000 to 2006, with citation rate equal to or higher than 20 times were retrieved in China National Knowledge Infrastructure(CNKI) by December 27, 2010. These articles were statistically analyzed according to publication year, section type, author, and geographical distribution of units. Results A total of 68 highly cited papers were obtained. The citation frequency of the highly cited papers ranged from 20 to 94, with an average of 31.09 times. The highly cited papers were published in 2000 at most, accounting for 25.0%(17/68); followed by 2001,accounting for 20.6% (14/68); at least in 2006, accounting for 2.9% (2/68). Of the highly cited papers, experimental study articles was in the highest proportion of 30.9%(21/68); followed by field epidemiological investigation articles,accounting for 23.5%(16/68); editorial, review articles accounting for 10.3%(7/68) and 8.8%(6/68), respectively;short reports, case reports, meeting records etc were not highly cited papers. The number of highly cited papers in editorial, expert forums, academic contend accounted for higher proportion of total number in corresponding section types(7/19, 3/11, 3/7). Highly cited papers came from 13 provinces(municipalities), there were 10 authors contributed two or more highly cited papers, and 8 units contributed two or more highly cited papers. Conclusions Adequate space should be given to experimental research, field epidemiological investigation, editorial, expert forums andacademic contend articles due to their high rate of citation. More attention should be paid to further consolidate and expand excellent authors group, and to intensify the invitation for key issues from influential experts.
