As firms switch from defined benefit plans to defined contribution plans, employees bear more responsibility for making decisions about how much to save. The employees who fail to join the plan, or who participate at a very low level, appear to be saving at less than the predicted lifecycle savings rates. Behavioral explanations for this behavior stress bounded rationality and self-control and ...

An algorithmic approach to constructing mixed-level orthogonal and near-orthogonal arrays Quasi Monte Carlo simulations of Brownian sheet with an application to interest rate stochastic string model A method for generating uniformly scattered points on the Lp-norm unit sphere and its application in statistical simulation A new class of model-robust designs A method for screening active effects ...

Various barriers for the uptake of energy-efficiency measures in the domestic sector have been identified. Projects try to quantify the effect of individual barriers like transaction costs, information lack, access to technologies or convenience. We propose to use the ‘consumer choice chain’ as a wider framework to understand energy-efficiency choices by domestic consumers. This allows comparis...

A general theory is developed for constructing the asymptotically shallowest networks and the asymptotically smallest networks (with respect to formula size) for the carry save addition of n numbers using any given basic carry save adder as a building block. Using these optimal carry save addition networks the shallowest known multiplication circuits and the shortest formulae for the majority f...

PURPOSE The purpose of this paper is to show how over the last 18 months Bolton Hospitals NHS Trust have been exploring whether or not lean methodologies, often known as the Toyota Production System, can indeed be applied to healthcare. DESIGN/METHODOLOGY/APPROACH This paper is a viewpoint. FINDINGS One's early experience is that lean really can save lives. The Toyota Production System is a...

Constructivism is the Piagetian notion that learning leads the child to develop new types of representations. For example, on the Piagetian view, a child is born without knowing that objects persist in time even when they are occluded; through a process of learning, the child comes to know that objects persist in time. The trouble with this view has always been the lack of a concrete, computati...

Multisensory integration of cross-modal stimulus combinations yielded responses that were significantly greater than those evoked by the best component stimulus.

Health insurance characteristics shift at age 65 as most people become eligible for Medicare. We measure the impacts of these changes on patients who are admitted to hospitals through emergency departments for conditions with similar admission rates on weekdays and weekends. The age profiles of admissions and comorbidities for these patients are smooth at age 65, suggesting that the severity of...
