“Why do we need to model
the science system?”
Talk at the seminar of the Eindhoven Centre for Innovation
Sciences, June 2, 2016
Andrea Scharnhorst, Royal Netherlands Academy of Arts and Sciences, DANS
Story line
• How got I roped into this?
• What kind of models do we hunt for?
• There is no one model of science – but there is also not really an overview
about them or a tool box
• Why do we need them?
• Do we have enough good data for predictive models of science dynamic?
• Modeling and measuring of science – living apart together
• Barriers and actions
• If only I had ….
