Duties of the publisher

The publisher ensures the editorial independence of the journal, maintains the permanent availability of the published record, and supports the editors in handling ethical issues, corrections and retractions.

Corrections, retractions and expressions of concern

Minor errors that do not affect the conclusions are corrected by publishing a correction notice linked to the article. Articles affected by serious errors, plagiarism, duplicate publication, fabricated or falsified data, or unethical research are retracted following the COPE retraction guidelines; the retracted article remains available and is clearly marked as retracted, together with the reason. Where an investigation is ongoing, the editors may publish an expression of concern.

Complaints and allegations of misconduct

Complaints about the journal's processes, or allegations of misconduct concerning submitted or published work, should be sent to kakriba@aol.fr with supporting evidence. They are handled confidentially, the persons concerned are given the opportunity to respond, and the complainant is informed of the outcome. Complaints about the publisher may be addressed to a@sigma-horizon.xyz.
