Links forecasting and planning with policymaking in social and societal systems and presents a planning and forecasting methods taxonomy which combines with policymaking and interactive simulation as an inquiry method for planning. A case study of university manpower development illustrating interactive simulation/gaming and its potentials for…

In this article, the author discusses the use in policy analysis of models that incorporate uncertainty. He believes that all models should consider incorporating uncertainty, but that at the same time it is important to understand that sampling variability is not usually the dominant driver of uncertainty in policy analyses. He also argues that…

The importance of myth and ritual in understanding the use of computer simulators in higher education is considered. Myths are commonly held beliefs that maintain social solidarity and reduce ambiguity; rituals serve a similar function, but they involve actions in addition to words. Examples of common myths and rituals are used to illustrate the…
