Theories that predict u-shaped and inverse u-shaped relationships are ubiquitous throughout the social sciences. As a result of this widespread interest in identifying non-monotonic relationships in data and the well-known problems with standard parametric approaches based on quadratic...

Increasingly simulations have been required as supportive evidence to management of proposed system changes. It has long been recognized that the computer running costs of simulations are strongly influenced by the synchronization mechanism used. Recently the time indexed list has been proposed...
