Manuscripts with poor grammar, unclear phrasing, or typographical errors will be rejected at the initial editorial screening.
Authors are encouraged to use professional editing services prior to submission.

Declaration of Submission

By submitting a manuscript, authors confirm that:

1. The work has not been published previously, except as a preprint or thesis.
2. The manuscript is not under consideration elsewhere.
3. All authors have approved the submission and consented to publication.
4. Accepted manuscripts will not be published elsewhere in the same form or language without written permission from JPPLG.

All submissions are screened for plagiarism using Turnitin. Only manuscripts with a similarity score below 20% are considered.

Authorship and Changes in Authorship

The JPPLG strictly regulates authorship changes.

1. Editors will generally not consider authorship changes after submission.
2. Authors must finalize the order and list of authors before submitting.
3. All authors must be entered in the online submission system.
4. Additions, removals, or rearrangements are discouraged and only allowed with editorial approval.
5. Authorship changes after editorial acceptance will not be considered.

Procedure:

1. The corresponding author must submit a written request explaining the reason for the change.
2. All authors (including those added or removed) must provide written consent.
3. Requests must use the official authorship change form provided during revision.
4. Unauthorized changes may result in rejection or article retraction.

Special cases:

1. If an author passes away during review, the remaining authors may acknowledge them in the Acknowledgment section.
2. If the deceased was the sole author, the manuscript will be withdrawn.
3. If a co-author becomes incapacitated, publication will be delayed until consent can be confirmed.

Generative AI Declaration

If authors use generative AI tools (e.g., ChatGPT, Gemini, Copilot, etc.), they must disclose this transparently.

1. AI tools cannot be listed as authors.
2. Use must be under human supervision.
3. Authors remain fully responsible for verifying accuracy and originality.
