Peer review is the root of academic and scientific publishing, ensuring the integrity, credibility, and reliability of published work. At PDP we are dedicated to upholding a meticulous and impartial evaluation process for all submitted manuscripts.
Every submission undergoes an initial technical assessment by the journal’s managing editor to verify adherence to standard formatting guidelines. Manuscripts meeting these criteria are forwarded to the Editor-in-Chief (EiC) for a decision on whether they qualify for the peer review process. Submissions deemed suitable proceed to peer review, while others are either returned to the authors for revision or declined.

Peer Review Model
All journals adhere to a single-blind peer-review process system, ensuring that the identities of reviewers remain confidential from the authors. Research articles, reviews, and all other article types submitted at PDP undergo a rigorous peer review process, typically evaluated by at least two-three independent, peer reviewers. Additionally, all manuscripts are meticulously screened for plagiarism using Turnitin software to identify overlapping or similar content, as part of the in-house editorial review.
All submissions made to PDP are initially reviewed for completeness before being evaluated by the Editor-in-Chief, who further decides their suitability for the peer review process. In cases where the Editor-in-Chief is listed as an author or has a potential conflict of interest with a manuscript, another member of the Editorial Board is appointed to oversee the review process. Academic Editor, typically the Editor-in-Chief or a conflict-free member of the Editorial Board, considers peer review reports when making both preliminary and final decisions, though they are not obligated to follow the recommendations provided. A significant concern raised by a single peer reviewer or the Editor may lead to the rejection of the manuscript. Authors are provided with comprehensive peer review reports alongside the editorial decision.
Editorials, Book Reviews, Commentaries and other manuscripts that do not report primary research or secondary analysis of primary research may be accepted without any peer review.
