In order to prevent cases of scientific misconduct the Editorial Board has procedures in place to deal with cases of "Ghost-writing", "Guest Authorship", "Plagiarism" and "Self-plagiarism".
Ghost-writing: A situation where someone makes a substantial contribution to a publication without revealing his or her participation as one of the authors or without being mentioned in the acknowledgments attached to the publication.
Guest Authorship or Honorary Authorship: A situation where one or more authors are cited as making a significant contribution to a work were as in reality the contribution is insignificant.
Plagiarism: The act of using someone else's work as one's own without acknowledging the source of that work.
Self-plagiarism: The act of using your own earlier published work without acknowledging the source of that work.
