At least 25 per cent of researchers worldwide have a poor understanding of plagiarism and ethics, according to a new survey.

The report titled "Author Perspectives on Academic Publishing: Global Survey Report 2018" provides insights into various aspects of research publication such as challenges authors face in manuscript preparation, communicating with journals and responding to peer reviewer comments.

Over 7000 researchers from India, Republic of Korea, Japan, China and Brazil were interviewed for the survey conducted by Editage, a global scholarly communications firm.
