Credit for publication

During consideration for retention, tenure, promotion, and raises administrators in academia tend to count 1 physics publication = 1 chemistry publication = 1 earth science publication = 1 biology publication = .....  This is unjust.  Publication rates (and the difficulty of generating original publishable research) are different in different fields (and different in different subfields).
