JCEP, following the COPE principles (https://publicationethics.org), is committed to maintaining the integrity of published scientific records. If errors or irregularities are discovered, corrective actions are taken to accurately inform readers. Corrections (Corrigenda and Errata)
Minor Errors: Errors that affect the accuracy of the article but do not significantly invalidate the conclusions are usually corrected by publishing a a Correction (or Erratum). The author is required to promptly notify the editor or publisher of a significant error or inaccuracy in their published work and cooperate in correcting the article.
Copyright Changes: Adding, deleting, or changing the order of authors after submission requires the formal submission of a Post-Submission Copyright Amendment Form (https://zenodo.org/records/17750189/files/Authorship_Change_Request_Form.docx?download=1) and the express written approval of all authors and the journal editor. Minor copyright amendments (e.g., spelling) may be made after acceptance. However, adding, deleting, or changing the order of authors after acceptance or publication is only considered in exceptional circumstances and generally requires approval from all authors and the journal editor. Unauthorized changes may result in rejection or disqualification.
Retractions
Fundemental Errors or Misconduct: In rare cases where the interpretation or conclusions of the article are significantly weakened by major errors (which may include fraud, distortion, or falsification of data), an article may be retracted. The editor's decision to retract an article is based on the credibility of the article.
Retraction Procedure:
A Retraction notice is published online and is two-way linked to the original article. The original article remains online but is usually marked “Retracted article,” and the retraction notice provides the reason for the action. In extreme cases, particularly where the infringement is confirmed, the author's institution may be notified. The journal follows COPE's Retraction Guidelines (https://publicationethics.org/guidance/guideline/retraction-guidelines).
Expressing Concern
An Editor Expression of Concern (EEoC) is a statement issued by editors to alert readers to serious concerns that affect the integrity of a published article, particularly if a lengthy investigation into the integrity of the research is underway. EEoCs are published and listed, often acting as an interim measure until the investigation is completed, possibly leading to a Correction or Retraction.
Delete Content
In exceptional circumstances— such as when content is found to be defamatory, infringes intellectual or legal property rights, or poses an immediate and serious health risk —JCEP reserves the right to temporarily or permanently remove an article from its online platforms.
