Using data from China's Urban Household Survey and exploiting China's mandatory retirement policy, we use the regression discontinuity approach to estimate the impact of retirement on household expenditures. Retirement reduces total non-durable expenditures by 21 percent. Among the categories of non-durable expenditures, retirement reduces work-related expenditures and expenditures on food cons...

control strategies for these codes. We have developed a parameterizable benchmark called MOL that captures a wide range of realistic Method-of-Lines codes. We are using this benchmark to develop performance models that can be used to achieve specific optimality criteria under the available (and

The method of lines (MOL), a semianalytical procedure, is well known to experts in computational techniques in electromagnetics. The range of applications of the method has increased dramatically in the past few years; nevertheless, there is no introductory paper to initiate a beginner to the method. This paper illustrates the application of the MOL to solve Laplace’s equation in rectangular an...

In this paper we describe a final-year undergraduate honours course that requires multimedia computing students to create narrative auditory and visual displays. The aim was to use discontinuity as a catalyst for creativity by getting students to tell a story in non-speech sound and in vision in which each medium conveyed a different mood.

A battle management system for comprehensive ballistic missile defense must perform with near perfection and extraordinarily reliability. It will be complex to an unprecedented degree, untestable in a realistic environment, and provide minimal time for human intervention. The feasibility of designing and developing such a system (requiring upwards of ten million lines of code) is examined in li...

The asymptotic behavior of Christoffel functions is established at points of discontinuity of the first kind.

A piecewise smooth mapping of the three-dimensional Euclidean space is derived from a discrete-time model of combat. The mathematical analysis of this mapping focuses on the effects of discontinuity caused by the defender’s withdrawal strategy—a prime component of the original model. Both the asymptotics and the transient behavior are discussed, and all the behavior types noted in the title are...

What explains the perpetuation of political dynasties in democracies? A handful of recent investigations using data from the United States and other candidatecentered electoral environments have pointed to a causal effect of incumbency on dynasty formation. However, dynasties exist in party-centered environments as well—and, importantly, the causal mechanisms underlying their formation may diff...

The mass, momentum, and energy conservation requirements at wave fronts (or surfaces of discontinuity) are reduced to a form suitable for use in the coupled thermoplastic analysis. Constitutive equations are introduced in these relations, and, for one-dimensional situations, it is shown that an isothermal (or adiabatic) wave front separating regions of elastic and plastic behavior will propagat...

A suitable spatial discretisation with 7 point formula in the method of lines is introduced. It is shown that, this method is capable of solving some kinds of Burgers' equation and comparisons are made with published analytic solutions .
