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.

Papers featured in the World Journal of Gastroenterology from 2006 to 2007

AIM： TO analyze papers published in the World Journal of Gastroenterology （WJG） from 2006 to 2007. We investigated the highly cited papers for geographic distribution of the cited authors, as well as the distribution of the citing journals and year of citation. METHODS： Papers published in WJG from 2006 to 2007 and their citations were retrieved from the Science Citation Index Expanded （SCIE）. The papers and their citations were analyzed according to bibliometric methods, including the number of citations for a given paper, the distribution of the highly cited papers, the geographic distribution of the cited authors, and the years of citation. RESULTS： Two thousand five hundred and six papers published in WJG from 2006 to 2007 were collected through SCIE, and 2335 of these were categorized as articles, reviews or proceedings. In 2006 and 2007, the average citation rate was 85.08% and 70.48%, respectively, and the average number of citations per paper was 4.33 and 2.51. Among the 2506 papers, 1963 were cited 8788 times by other articles. The mean number of citations per paper was 3.51. The papers with over three citations accounted for 54.72% of all those that were cited, and the total number of citations accounted for 85.38% of the total of 8788 citations. Thirteen papers were cited over 30 times and the highest number of citations for any one paper was 98. The cited authors came from 70 different countries or regions, with China, Japan and the United States being the most frequent. The highest average citation rate and number of citations per paper were for authors from Canada （96.30%, 6.89）, Hungary （92.31%, 5.62）, Australia （88.46%, 5.46）, Germany （87.04%, 5.33）, and Spain （87.50%, 5.11）. The impact factor was 2.081 and the self-citation rate was 9.41% in 2008. The papers published in WJG in 2006-2007 were cited by 1597 journals. CONCLUSION： The papers in WJG have a high number of citations, and have been cited in numerous journals by authors from various countries. The results imply that WJG has an influential academic profile in gastroenterology around the world.

Improvement analysis of article quality in World Journal of Gastroenterology during 2008-2012

AIM:To understand the changes and development of World Journal of Gastroenterology(WJG)in recent years.METHODS:The Journal Citation Report(JCR)and SCI-E database of the ISI Web of Knowledge were used to search the articles and data of related indices in WJG during 2008-2012.Bibliometric methods were used for statistical analysis of the author’s degree of collaboration,collaboration rate,the first author’s publications,high-productivity authors,the authors’origins in each year;the distribution of the countries and journals of the authors citing WJG papers was also analyzed.In addition,the indices related to this journal in each year were compared with the data from 6 SCI journals in the field of gastroenterology in the 2012 volume.RESULTS:A total of 4409 papers in WJG were examined in this study.For the period 2008-2012,the selfcitation rate was 8.59%,6.02%,5.50%,4.47%and5.21%.Of a total of 3898 first authors,3526 published1 paper,291 published 2 papers,59 published 3 papers,and 22 published 4 or more papers.The origin of WJG authors covered the six continents,and the majority came from Asia,Europe and North America.The number of countries of origin of WJG authors was65,66,61,65 an 60 for the period 2008-2012.Authors from 66 countries cited a total of 3194 of the 4409 papers,and these citations were found in 1140 journals.CONCLUSION:The results suggest that WJG has stayed on the track of normal international publication and all the indices of this journal are stable and reasonable.     

The wealth of nations and the dissemination of cardiovascular research

Background

This study aimed at understanding whether investigators from less wealthy countries were at a disadvantage in disseminating their research, after accounting for potential differences in research quality and infrastructure.

Methods and Results

In this bibliometric analysis a representative random selection of 10% (n = 1002 studies) of all abstracts submitted to the European Society of Cardiology (ESC) congress 2006 was followed for publication and citation from September 2006 to December 2011. The main variable of interest was the per-capita gross domestic product (GDP) of the country of the principal investigator. Using multivariable models that adjusted for socioeconomic indicators and previously identified markers of research quality, we examined the relationship between per-capita GDP and three study endpoints: Acceptance at the ESC congress, full-text publication, and number of two-year citations. Among 1002 abstracts from 63 countries, per-capita GDP was positively correlated with all three study endpoints. After adjusting for markers of research quality and infrastructure, per-capita GDP remained a strong predictor for acceptance at the ESC congress (adjusted OR for every 10,000 USD increase in per-capita GDP, 1.44; 95% CI, 1.15 to 1.80), full-text publication within 5 years (adjusted OR, 1.49; 95% CI, 1.17 to 1.90), and high citation frequency (adjusted OR, 2.30; 95% CI, 1.31 to 4.04). These findings were largely consistent in a subgroup of abstracts of high-quality, prospective clinical trials.

Conclusion

Investigators in less wealthy countries face challenges to disseminate their research, even after accounting for potential differences in the quality of their work and research infrastructure.
