The paper presents a real-time physically based simulation of object damage and motion due to a blast wave impact. An improved connected voxel model is used to represent the objects. The paper also explores auxiliary visual effects caused by the blast wave that increase visual believability without being rigorously physically based or computation-

Refrigerator ownership in rural China increased from 14% to 45% over the period 2001-2010.We test the impact on demand for food, particularly meat, using fixed-effect and demand system approaches based on provincial data. Results suggest that rising refrigerator ownership had a negative effect on rural at-home meat demand.

In this paper we derive asymptotic tests for general linear hypotheses on variance components using repeated variance components models In two examples the two way nested classi cation model and the two way crossed classi cation model with interaction we explicitly investigate the properties of the asymptotic tests in small sample sizes

This paper empirically analyses entry by generic firms into the strictly regulated Spanish pharmaceutical market. We estimate a fixed effects negative binomial entry model using a panel of 77 active ingredient markets during the period 1999– 2005. The results show that generic entry depends positively on revenues, the age of themarket, and the number of previous brand-name competitors, and nega...

Many studies have argued that relative income predicts individual well-being. More recently, it has been suggested that the relative rank of an individual’s income, rather than how that income compares to a mean or reference income, is important. Here the relative rank hypothesis is examined along with the additional hypothesis that individuals compare their incomes predominantly with those of ...

A meta-analysis assessed the behavioral impact of and psychological processes associated with presenting words connected to an action or a goal representation. The average and distribution of 352 effect sizes (analyzed using fixed-effects and random-effects models) was obtained from 133 studies (84 reports) in which word primes were incidentally presented to participants, with a nonopposite con...

This paper presents an industrial application of “Dysfunction Mode and Effects Critical Analysis” (DMECA) to determine and analyze possible dysfunctions in a complex management process. The approach conceptually derived from the Failure Mode and Effect Critical Analysis (FMECA) technique. DMECA enables user to analyze all possible dysfunctions of management processes, identify the subsequent ef...

Consider a generalized linear model with a canonical link function, containing both fixed and random effects. In this paper, we consider inference about the fixed effects based on a conditional likelihood function. It is shown that this conditional likelihood function is valid for any distribution of the random effects and, hence, the resulting inferences about the fixed effects are insensitive...

Received analyses based on stochastic frontier modeling with panel data have relied primarily on results from traditional linear fixed and random effects models. This paper examines extensions of these models that circumvent two important shortcomings of the existing fixed and random effects approaches. The conventional panel data stochastic frontier estimators both assume that technical or cos...
