Violation of publication ethics can take several forms, including data manipulation, duplicate publication, simultaneous submission, plagiarism, and salami slicing. Upholding publication ethics is important to establish the integrity and credibility of scholarly research. It is the responsibility of authors to avoid fabricating or manipulating data, plagiarizing, submitting manuscripts to multiple journals simultaneously, or including guest authors who did not meaningfully contribute. Organizations like COPE and ICMJE provide guidelines to help authors, editors, and reviewers maintain high standards of ethical publication practices.
