IMPACT VITALITY - A MEASURE FOR EXCELLENT SCIENTISTS

In many countries and at European level, research policy increasingly focuses on 'excellent' researchers. The concept of excellence however is complex and multidimensional. For individual scholars it involves talents for innovative knowledge creation and successful transmission to peers, as well as management capacities. Excellence is also a comparative concept, implying the ability to surpass others [TIJSSEN, 2003]. Grants are in general awarded based on assessments by expert committees. While peer review is a widely accepted practice, it nevertheless is also subject to criticism. At higher aggregation levels, peer assessments are often supported by quantitative measures. At individual level, most of these measures are much less appropriate and there is a need for new, dedicated indicators.
