Ethics in publication

Michael Wallace, MD, MPH, FASGE, from the Mayo Clinic in Jacksonville, Florida, USA and the Editor-in-Chief of GIE: Gastrointestinal Endoscopy discusses this article “Ethics in publication.”

This articles reviews key ethical issues that arise in publication of scientific article such as authorship, plagiarism, and text-recycling. The intense pressure to publish in academia has led to rare but high profile cases of scientific misconduct. The Editors of GIE and Endoscopy wish to provide clear guidelines to authors on how to avoid common ethical pitfalls and to notify authors how our journals handle such incidents.

Together with Professor Peter Siersema, the Editor-in-Chief of Endoscopy, we review key topics such plagiarism and text recycling (republication of copyrighted text by the same author), authorship guidelines, data fabrication, and duplicate publication. We provide examples of how our journals detect and deal with suspected and confirmed cases of ethical violations, and list reference for international guidelines such as the Committee on Publication Ethics and the International Committee of Medical Journal Editors.

Our goals is to prevent such issues by making authors aware of common pitfalls and how to avoid them.
