De invloed van managers op individuele prestaties van werknemers

Abstract In this paper, we want to know how knowledge, available and shared in social media networks (like Twitter, Facebook, Hyves, blogs, wickis etc,) does influence processes of risk definition in policy-making processes regarding ‘wicked problems’ and how this can be explained? Little is known about how policy relevant knowledge in social media based networks is created and shared and how it influences the shaping of public policy processes. The research strategy in this paper involves a comparative case study. The following two Dutch cases could be relevant: the vaccination against uterus cancer and the vaccination against the Mexican swine flu. In both cases, the RIVM (Dutch research institute for public health) played a major role. Based on the two case studies, the most important conclusion is that knowledge, produced in social networks, had no influence on processes of risk definition in policy-making processes. Three explanations are given. First, the factor time plays an important role. In 2009, social networks were less prominent than in 2011 (Lievrouw, 2011). Second, an institutional approach can explain why policymakers of the RIVM ignored knowledge, produced in social networks (March & Olsen, 1989). Finally, from a strategic point of view, the RIVM may have chosen not to pay attention to knowledge, produced in social networks (Lindblom, 1959).
