Assessing research impact in academic clinical medicine: a study using Research Excellence Framework pilot impact indicators

BACKGROUND Funders of medical research the world over are increasingly seeking, in research assessment, to complement traditional output measures of scientific publications with more outcome-based indicators of societal and economic impact. In the United Kingdom, the Higher Education Funding Council for England (HEFCE) developed proposals for the Research Excellence Framework (REF) to allocate ...

Research output indicators are not productivity indicators

Integrated Impact Indicators (I3) compared with Impact Factors (IFs): An alternative research design with policy implications

In bibliometrics, the association of “impact” with central-tendency statistics is mistaken. Impacts add up, and citation curves should therefore be integrated instead of averaged. For example, the journals MIS Quarterly and JASIST differ by a factor of two in terms of their respective impact factors (IF), but the journal with the lower IF has the higher impact. Using percentile ranks (e.g., top...
