2. Unacceptable Forms of Academic Misconduct

• Copying text, data, or images without proper citation or acknowledgment.
• Duplicating previously published work, including self-plagiarism.
• Submitting the same manuscript to more than one journal simultaneously (multiple submission).

3. Actions in Case of Proven Plagiarism

• The manuscript will be rejected prior to publication.
• If plagiarism is identified after publication, the article will be formally retracted and publicly announced on the journal’s website.
• Authors found to have committed serious ethical violations may be subject to temporary or permanent bans on future submissions.

Through this plagiarism policy, LUMEN reaffirms its commitment to safeguarding scientific integrity, maintaining publication quality, and respecting the intellectual property rights of authors.
