Plagiarism is when an author attempts to pass off someone else’s work as his or her own. Duplicate publication, sometimes called self-plagiarism, occurs when an author reuses substantial parts of his or her own published work without providing the appropriate references. This can range from getting an identical paper published in multiple journals, to taking material from other sources, including the Internet, and deliberately failing to give credit in your paper to the original source. It can also involve improper use of citation and documentation in a way that constitutes plagiarism, even though unintended.
Plagiarism is a very serious violation of academic rules. It is unethical and dishonest and therefore, prohibited by Language in Africa. There is no acceptance of plagiarized manuscripts. By submitting a manuscript to the journal the author guarantees that it is an original manuscript and is unpublished work and is not under consideration elsewhere.
As mentioned, our editorial policy accepts revised and elaborated English versions of papers earlier published in languages other than English and French. But submitting such revised versions, the authors should inform the editors explicitly that the submission is a revised version of an earlier published paper and, once the paper is accepted, should provide the reference to the original publication.
