Authorship
Each of the manuscript’s authors should meet all three of the following criteria: (1) has made a substantial contribution to the design of the study, the collection of the data, or the analysis or interpretation of the data; (2) has drafted the manuscript or helped revise it, shaping its intellectual content; (3) has approved of the submitted manuscript. Each author should be able to take public responsibility for a portion of the paper’s content, and should be able to identify the co-authors who are responsible for the remaining material.

Contributors who do not meet the criteria for authorship should be listed in the Acknowledgements section. Examples of those who might be acknowledged include a person who provided purely technical help or writing assistance and a department chairperson who provided only general support.
