A conflict of interest may arise in the event that a reviewer, a member of the editorial board, or an editorial staff member is related to an employee who may subjectively influence the decision regarding publication. Interpersonal conflicts can be caused by relationships with the employer, family ties, engagement in financial relations, etc. Conflicts may also arise as a result of academic competitions, or due to personal preferences or aversions. The editor or any member of the editorial board should be free from responsibility for reviewing manuscripts in the event of any conflict of interest. The editor-in-chief and the editorial board require all authors of journal articles to provide information about possible relevant competing interests, and to publish improvements if a conflict of interest has been revealed after publication. If necessary, some additional action may be carried out, such as the publication of a refutation or an expression of concern.
