There is considerable correspondence between theories and models used in biology and the social sciences. One type of model that is in use in both biology and the social sciences is the fitness landscape model. The properties of the fitness landscape model have been applied rather freely in the social domain. This is partly due to the versatility of the model, but it is also due to the difficulties of transferring a model to another domain. We will demonstrate that in order to transfer the biological fitness landscape model to the social science it needs to be substantially modified. We argue that the syntactic structure of the model can remain unaltered, whilst the semantic dimension requires considerable modification in order to fit the specific phenomena in the social sciences. We will first discuss the origin as well as the basic properties of the model. Subsequently, we will demonstrate the considerations and modifications pertaining to such a transfer by showing how and why we altered the model to analyse collective decision-making processes. We will demonstrate that the properties of the target domain allow for a transfer of the syntactic structure but don’t tolerate the semantic transfer.
Following the 1953 flood, the Dutch delta has been shut off from the sea by a series of dams and dykes. This closing-off transformed the delta from a constantly changing estuarine environment into a freshwater body. A different way of thinking about 'nature' in the period 1970-1980 led to the policy proposal to transform the Haringvliet, one of the shut-off water bodies, back to its natural state. The intended first step was a minor change in the sluice control of the dam that separates the Haringvliet from the sea. However minor, this step was never taken and it is still an ongoing policy debate whether the sluice should be slightly opened or not. This paper presents a coevolutionary analysis of why such a seemingly small change could take so much time and effort to become actualized. We demonstrate that the course of the policy process is determined through patterns of reciprocity between the physical and societal systems. Effects of measures are unpredictable, and the desired state of this water basin greatly varies between actors and over time. It is a combination of these factors that explains why the sluice control has not been changed yet.
The pace of societal change and the development of societal challenges have speeded up considerably during the last couple of decades, with substantial impact on different levels, i.e. ranging from global to local, or from business to government. When focusing on the public domain, these changes and challenges have had a major impact on public professionals, who face different and frequently changing questions. Mid-career programs in Public Administration (MPA) have the mission to support enrolled professionals in dealing with these changes and challenges. This article is about the development of such MPAs. Both substantive and didactic development is needed. To counter institutional inertia it seems vital to institutionalize a regular rethinking and adaptation of curricula and didactic strategies. This article identified some important points of attention and some options to deal with these in order to continuously improve the contribution of MPA programs to relevant and effective professional development and ongoing professional learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
