Clement TP. Authorship matrix: a rational approach to quantify individual contributions and responsibilities in multi-author scientific articles. Science and Engineering Ethics 2014;20:345-361
The author proposes a rational method for assessing the responsibilities of an author of a scientific multi-authormanuscript. This new paradigm conceptually divides an article into four basic elements for which individual responsibilities can be assigned: ideas, work, writing, and stewardship. The outcome is an authorship Matrix, that provides all necessary information for deciding the rank of an author.
