Plagiarism control and detection policy 
Plagiarism involves the use of ideas, words, data or material produced by others without their consent, and can occur in a variety of typologies (such as text, illustrations, computer coding, material downloaded from websites, other manuscripts or digital media), as well as unpublished or un-edited material (courses, presentations and grey literature).
PSE only publishes and encourages original, innovative, relevant and socially transferable works. Therefore, PSE verifies the originality of all manuscripts received. The author agrees that the manuscript will be examined with the aim of avoiding plagiarism and thus promoting academic integrity. PSE proceeds rigorously to review submissions submitted through the OJS platform using anti-plagiarism tools, especially CrossCheck.
Papers with total or partial plagiarism rates are systematically rejected, without the option of resubmission, since these actions are considered as unacceptable and punishable practices. This decision is communicated by transparently attaching a plagiarism report.
Reviewers, authors and the rest of the scientific community may raise suspicions of plagiarism that will be analyzed by the Editorial Team, following the correction and retraction guidelines of the Publications Ethics Committee.
