Dear RG colleagues,

This respected portal (i.e. RG) defines plagiarism as: The term “plagiarism” has different meanings, but it usually includes copying somebody else’s work without permission.

I may be somewhat old-fashioned, but please have the following golden rules on how to avoid plagiarism, especially Self-Plagiarism:

Finally, believe me, or not: If you make one plagiarizing, you may solve one problem and fall into many others where some of which may be described as a knockout. Again and again, please always remember that if there were accusations of plagiarism, it is not well for any researcher's reputation, in any meaning.
