Publication Ethics

Our journals follow the guidelines as set out in the Committee on Publication Ethics (COPE) andĀ International Committee of Medical Journal Editors (ICMJE) on handling potential conflicts of interest of editors, authors, and reviewers. Submissions from editors or members of the editorial board are assigned to other unrelated editors or editorial board members who will ensure unbiased review and decision. Editors-in-chief or handling editors with the assistance of editorial board have complete responsibilities for the peer-review process, decisions, and selection of articles.

There is a zero-tolerance policy towards plagiarism (including self-plagiarism) in our journals. Manuscripts are screened for plagiarism before or during publication, and if found they are rejected at any stage of processing. Other ethical issues, allegations of research misconduct or complaints are handled very seriously and investigations are carried out by the editors and/or editorial office, followed by actions such as rejection, withdrawal, or retraction of articles.
