2. The writers must make sure that what they have written is original, and if they have borrowed from others, they must have properly attributed or quoted them.

The Editorial Board will employ plagiarism detection technologies such as Ithenticate and Plagium X Checker. A 20% maximum tolerance level is set for similarity.
