Conflict of interest
A conflict of interest may exist when an author (or the institution), a referee or a member of the editorial have financial or personal relationships that could inappropriately influencing their behavior. This conflict can exist even if the subject believes that these relationships do not influence.
The editorial board of the magazine has to manage in the best way possible conflicts of interest (for example, through the system of anonymous referees double-blind), and authors can be requested a statement on the matter.
