Plagiarism and research integrity
Every submitted manuscript is screened for textual overlap. Plagiarism — in any form — leads to immediate desk rejection and may trigger further institutional action.
Screening tool and threshold
CJES uses Turnitin / iThenticate for similarity detection. Thresholds: overall similarity below 20%, and similarity from any single source below 5%. The handling editor reviews the report — context matters (a 25% overall score concentrated in properly cited references differs from 15% from one undisclosed source).
Forms of plagiarism
CJES considers all of the following plagiarism:
- Verbatim copying without attribution
- Mosaic plagiarism (paraphrasing without citation)
- Self-plagiarism / text recycling without disclosure
- Duplicate submission to multiple journals
- Reproduction of figures or substantial portions without permission
Action on detection
Minor cases (likely unintentional, mostly missing citations): manuscript is returned for correction. Major or deliberate plagiarism: immediate rejection and notification to the corresponding author’s institution. Post-publication discovery: Retraction following the COPE retraction process. Authors found responsible may be barred from submitting to CJES for a defined period.
AI / large language model use
Manuscripts generated substantially by AI without disclosure or human accountability are treated as a form of plagiarism. See the AI / LLM use policy for full guidance.
