MEBIS is committed to maintaining an accurate and trustworthy scholarly record. Where substantial errors or concerns arise after publication, the editorial team evaluates the matter and selects a response proportionate to the evidence and seriousness of the problem, consistent with recognised publication-ethics guidance.

Corrections

A correction may be issued when an article contains a material but limited error that does not invalidate its main findings or conclusions, for example an incorrect figure label, affiliation, analytical value, or other substantive mistake. The correction notice describes the change and is linked to the original article. Minor typographical corrections may be handled without a formal notice if they do not alter interpretation, subject to an appropriate record of changes.

Expressions of Concern

An expression of concern may be issued where credible and potentially serious questions about an article remain unresolved, investigations are ongoing, or conclusive evidence cannot yet be obtained. The notice will describe the nature of the concern without making unsupported findings and will be linked to the original article.

Retractions

Retraction may be warranted when findings are unreliable owing to major error, data fabrication or falsification, plagiarism, unethical research, redundant publication that materially misleads readers, or other substantial integrity concerns. The Editor-in-Chief, or an independent authorised editor in cases of conflict, makes the final journal decision after appropriate review of evidence and an opportunity for author response.

Retraction notices must be clearly labelled, identify the affected publication and reasons for the action, and remain freely accessible and linked to the original record. The original article should generally remain available with prominent retraction labelling to preserve the scholarly record, except where removal is required by law, privacy, or substantial harm considerations.

Appeals and Updates

Authors may submit a reasoned request for reconsideration supported by new evidence. The journal will review appeals independently where feasible. New evidence may justify updating, replacing, or lifting an expression of concern or making a further corrective notice. Article metadata and indexing records should be updated where technically supported.
