Intellectual property is seriously concerned by the journal. On submission, all manuscripts are screened using the software ‘Turnitin’. If plagiarism (higher than 20% of similarity) is suspected, the editors will immediately inform the authors of the rejection. If plagiarism is proven after publication, the article will be retracted from the journal. The editors will contact all the authors’ institutions to explain the retraction of article and the authors’ behaviors. The event of retraction will also be officially announced as soon as possible on the journal website.
