Similarity Threshold

Maximum 20% Overall Similarity

Manuscripts exceeding this threshold must be revised and resubmitted. The Turnitin report and editorial comments will be provided simultaneously to guide revision.

Types of Plagiarism Covered

PTJI screens for all recognized forms of plagiarism as defined by COPE (Committee on Publication Ethics) and STM (International Association of Scientific, Technical, and Medical Publishers):

Verbatim Plagiarism

Word-for-word copying of another author's text without quotation marks or proper attribution, regardless of source language.

Paraphrase / Mosaic Plagiarism

Rewording another's ideas without attribution, or stitching together phrases from multiple sources to create a new text without citation.

Self-Plagiarism

Reusing substantial portions of an author's own previously published work without disclosure. Includes recycling data, methods, or discussion text.

Duplicate / Redundant Publication

Submitting the same manuscript simultaneously to multiple journals, or republishing data already published elsewhere without acknowledgment.

Salami Slicing

Artificially dividing a single study into multiple publications to inflate publication count, without each paper representing a distinct, complete contribution.

Idea / Concept Plagiarism

Presenting another researcher's hypothesis, theory, or research design as one's own, even if expressed in entirely different wording.

 

New Policy · COPE 2023 / ICMJE 2023

AI-Generated Text & Plagiarism Detection

AI-generated or AI-assisted text presents unique challenges for plagiarism screening. PTJI applies the following policy in accordance with COPE (2023), ICMJE (2023), and STM's Integrity Hub guidelines:

Permitted with Disclosure

  • Grammar and spell checking (e.g., Grammarly)
  • Paraphrasing assistance with full author revision
  • Translation support with verification
  • Literature search and summarization
  • Formatting assistance

Not Permitted

  • Generating original results sections, discussion, or conclusions with AI
  • Presenting AI-written text as the author's own intellectual work
  • Using AI to fabricate or modify research data
  • Submitting AI-generated text without disclosure
  • Listing AI tools as authors

AI-Text Detection Tools Used by PTJI Editors

Turnitin AI Writing Detector iThenticate AI Detection Copyleaks AI Content Detector Editorial Judgment

Mandatory AI Disclosure (ICMJE 2023)

Authors who used AI or AI-assisted tools in manuscript preparation must declare this in the Methods or Acknowledgments section, specifying: (1) the tool name and version, (2) the purpose of use, and (3) the specific section(s) affected.

Example declaration: "The authors used ChatGPT-4 (OpenAI, 2024) for grammar checking of the manuscript. The authors take full responsibility for the integrity of all content."

Self-Plagiarism, Prior Publication & Duplicate Submission

 

Preprints

Posting a manuscript on a recognized preprint server (e.g., medRxiv, bioRxiv, OSF Preprints) prior to submission is acceptable, provided this is disclosed in the cover letter. Authors must link the preprint to the final published article upon acceptance.

 

Conference Abstracts / Proceedings

Manuscripts based on previously published conference abstracts or proceedings are acceptable if substantially expanded (typically ≥30% new content). Authors must disclose the prior publication and explain the added value in the cover letter.

 

Simultaneous Submission

Submitting the same manuscript to more than one journal at the same time is strictly prohibited. PTJI cross-checks submissions against other journals when duplication is suspected. Violations result in immediate rejection and may be reported to authors' institutions.

Consequences of Plagiarism

PTJI follows COPE's flowcharts and guidelines when addressing suspected or confirmed plagiarism. Actions taken depend on the severity and stage of the manuscript:

1

Request for Revision

Minor similarity issues (<30%): authors requested to revise and resubmit with reduced similarity.

2

Rejection

Significant plagiarism (>30%) or undisclosed duplicate submission: manuscript rejected without peer review.

3

Retraction

If plagiarism is discovered post-publication, the article will be retracted per COPE Retraction Guidelines (2019) with a public retraction notice.

4

Institutional Notification

Serious misconduct cases reported to authors' institutions and potentially to COPE for further investigation.

Reporting Concerns & Appeals

Report Suspected Misconduct

Third parties who suspect plagiarism in a published PTJI article may contact the editorial office. All reports are treated confidentially and investigated in accordance with COPE guidelines.

Author Appeals

Authors who believe a plagiarism finding is incorrect may appeal in writing within 14 days of notification. Appeals must include a detailed explanation and supporting evidence (e.g., proof of original authorship, timeline of drafts).
