CORE JOURNALS - A REAPPRAISAL OF THE DIAMOND LIST

One component of research assessment has been, and will continue to be , the explicit (or implicit) ranking of journals. Despite the obvious limitations, citations data are generally used to generate rankings as they provide one of the few quantifiable aspects of a journal's perfo rmance. Previous ranking schemes based on multiple performance measure s constructed from citations data, such as the 'Diamond Core', can be criticised for their use of 'arbitrary' weighting schemes to generate their final rankings. This paper addresses this problem by applying ra nking techniques, namely, Data Envelopment Analysis and Integer Progra mming, which systematically allow for multiple performance measures.
