Plagiarism Policy

JPPDAS is committed to maintaining academic integrity and does not tolerate plagiarism. Every manuscript must be an original work, provide proper acknowledgment of sources, and comply with publication ethics.

1. Definition and Scope
Plagiarism is the use of another person’s ideas, text, data, images, tables, code, or work without adequate acknowledgment of the source, thereby presenting it as one’s own work.
Forms of plagiarism include:
• Copying text without direct quotation marks and proper attribution.
• Paraphrasing another person’s ideas or writing without citing the source.
• Combining portions from multiple sources without adequate acknowledgment.
• Using data, images, tables, or code belonging to others without attribution and permission when required.
• Translating another person’s work and presenting it as one’s own.
The inclusion of citations alone does not justify word-for-word copying without proper quotation marks.

2. Reuse of One’s Own Work
Authors must disclose and cite their previous work related to the manuscript. The reuse of text, data, or research results must be explained transparently and demonstrate new contributions.
The reuse of text is evaluated based on the amount, location, context, attribution, and copyright provisions. Representing previously published results as new findings without disclosure may be considered redundant publication.

3. Similarity Check
Manuscripts are checked using the similarity-checking software employed by the journal prior to peer review. A recheck may be conducted on revised versions or prior to publication.
The similarity report is used as a tool to assist the editor, not as sole evidence of plagiarism. The editor reviews matching sections, original sources, the accuracy of citations, and the context of their use.
A low similarity percentage does not guarantee that a manuscript is free of plagiarism, and a high percentage does not automatically prove a violation.

4. Author Responsibilities
Authors must ensure that:
• The manuscript is original, and all sources are properly acknowledged.
• Direct quotations are marked in accordance with the journal’s style guidelines.
• Paraphrases reflect the author’s understanding and are accompanied by citations.
• The use of third-party material complies with applicable license terms or permissions.
• The use of prior works is disclosed transparently.
The use of editing services, translation services, or AI tools does not absolve the author of responsibility for the originality of the manuscript.

5. Pre-Publication Handling
If suspected plagiarism is identified, the editor will review the evidence and request an explanation from the author. The editorial process may be postponed pending the review.
Depending on the nature and severity of the issue, the editor may:
• Request corrections to citations, attributions, or wording if the issue is minor and can be resolved.
• Reject the manuscript if there is substantial plagiarism or unresolved violations.
• Contact the relevant institution if necessary for further investigation.
The decision will be communicated to the author along with the relevant rationale.

6. Post-Publication Handling
Allegations of plagiarism in published articles will be investigated by comparing the article with relevant sources and requesting a response from the author.
Actions may include corrections for minor issues, an “expression of concern” if sufficient grounds are found during the investigation, or retraction of the article if substantial plagiarism is proven.
Notifications of corrections or retractions are linked to the article and transparently explain the reasons for the action. Retracted articles remain part of the publication record with clear labeling, unless there are legal reasons or special circumstances that require their removal.

7. Reporting and Appeals
Readers, reviewers, or other parties may report suspected plagiarism through the journal’s official contact channels, including the article’s identification, the source for comparison, and the section in question.
Reports are handled objectively and with confidentiality maintained to the extent possible. Authors may appeal a decision by providing reasons and supporting evidence. Objections are reviewed by an editor who has no conflict of interest.

8. Decision-Making Principles
The handling of suspected plagiarism follows the guidelines of the Committee on Publication Ethics (COPE). Actions are determined based on evidence, the extent of the violation, its impact on the article’s integrity, and the author’s response—not solely based on similarity scores.

JPPDAS implements a policy to deal with plagiarism in submitted articles. Plagiarism is the use of another author's words and ideas and acknowledged as one's own without citing the source. Papers to be published are original papers that have never been published. Quotation marks are needed when making a direct quote accompanied by a mention of the source. Text longer than two or three sentences or graphic material copied from other sources requires permission from the copyright holder and, if applicable, the original author. We use Turnitin to check all manuscripts to avoid plagiarism. Plagiarism should not exceed 10% and the value is distributed in the manuscript. The main editor will pay close attention and will take action based on the level of plagiarism.
