Duplicate Publications

The Davao Research Journal (DRJ) does not accept manuscripts that have been previously published, simultaneously submitted, or substantially similar to works published elsewhere in local, national, or international journals. Redundant or duplicate publication constitutes a serious breach of publication ethics and research integrity.

All submitted manuscripts may undergo similarity and originality screening using appropriate plagiarism-detection software and editorial evaluation procedures. Manuscripts identified as duplicate, redundant, or overlapping substantially with previously published works may be rejected, retracted, or subject to further editorial investigation in accordance with the journal’s publication ethics policies and internationally recognized ethical publishing standards.
