You will be required to warrant that the manuscript is your original work; it is being submitted for first publication, it should not have been previously published in its current or similar form, and that it is not being considered for publication elsewhere.
Submitted articles shall be checked with duplication-checking software. Where an article is found to have plagiarised other work, or included third-part copyright material without permission or with insufficient acknowledgment, or where the authorship of the article is contested, IJE editors reserve the right take action including, but not limited to: publishing an erratum or corrigendum (correction); retracting the article; alerting the author’s head of department or dean, his/her or employer or funding body, institution or the relevant academic bodies or societies; reject any submitted manuscript.

Multiple, Concurrent and Redundant Publication
You should not publish manuscripts describing essentially the same research in more than one journal of primary publication; neither should you submit for consideration a paper that has been published previously, except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint. Under such circumstances, there should be agreement between authors and editors on the secondary publication, which must reflect the same data and interpretation of the primary document. Also, the primary reference must be cited in the secondary publication. You should not submit manuscripts that overlaps substantially with another in terms of hypothesis, data, discussion points or
conclusions; unless substantive cross-referencing and justification is made.
