Dr. Barter has received a large research grant that will follow the health behaviors of 1,000 people for up to 5 years. This will create an enormous amount of data, and Dr. Barter encourages other researchers to use his data for their own analyses. However, he requires that his name be listed on each paper even though he has no role in the actual analysis or writing of the new report. This is an example of:
O appropriate credit.
O gift or guest authorship.
O ghost authorship.
O mutual authorship.
