Abstract: | The term excellence is the key concept of the European science policy. The research funding is supposed to focus on the strengthening of excellence as well as on its integration into networks and clusters. However, one seems to presuppose the criteria of excellence as self-explanatory. Studies show that scientific reputation not only grounds on outstanding achievements in research and teaching but also on social capital. This raises the question, whether networks and clusters of excellence really integrate the scientifically best scientists. It is also possible that groups with a remarkable amount of social capital reproduce themselves underthe cover “excellence”. Hence, scientific excellence would be nothing more than a metaphor. |
