Fundamental Analysis of Duplicate Publication of Re¬search Papers

Duplicate publication is publication of a paper which overlaps with another published paper in many important parts and is essentially considered unethical. So, this study was carried out to evaluate the pat¬tern of duplicate publication as well as determining the causes of this phenomenon among the papers of researchers of Isfahan University of Medical Sciences. All cases of discovered duplicate publication during 2005 to 2008 re¬ferred to the committee of ethics were studied. After confirmation of du¬plicate publication, the cases were assessed by interviewing and review¬ing the documents; then the fundamental roots was drawn. After analyz¬ing the cases and categorizing the fundamental causes, a classification and definition of duplicate publication phenomenon was presented. Out of the nine underwent duplicate publication papers, eight were "Copy publishing" and the other was "Least publishable unit" (or Salami Slic¬ing). From sixteen journals where papers were published, only five had impact factor and six were Iranian. Seven papers were in Persian and two in English. According to our findings, our countryʹs scientific community is not familiar with the professional rules of scientific and research work, so most of the duplicate publications are uninformed and non-intentional. To prevent duplicate publishing, besides taking legal action against duplicate publication with copy right infringement, the way to interact with the trend of review of papers, correspondence with the editors of journals, and announcement of rules of committee of ethics in research should be taught to faculty members and researchers.
