The annual percent change (APC) has been adopted as a useful measure for analyzing the changing trends of cancer mortality and incidence rates by the NCI SEER program. Difficulties, however, arise when comparing the sample APCs between two overlapping regions because of induced dependence (e.g.,...

We propose a mixture model for data with an ordinal outcome and a longitudinal covariate that is subject to missingness. Data from a tailored telephone delivered, smoking cessation intervention for construction laborers are used to illustrate the method, which considers as an outcome a...

In order to improve the wear resistance of the cable bolt and increase its life-time during operation, plasma nitriding was employed to obtain a protective nitriding layer on its surface. The microstructure, phase constitution, microhardness and wear resistance of the nitriding layer were...

Focusing on the cognitive process of managerial decision making, we argue that both organizational and personal international experiences contribute to managerial knowledge structure which in turn influences firms' foreign direct investment decisions. Given the decision task context of...

In practice, when both survival and quantitative outcomes are of interest, we encounter outcomes of mixed type: a censored outcome and a quantitative outcome. Joint modeling of the survival and quantitative outcomes rather than analyzing the outcomes separately has become a method of choice for...

Drawing on recent advances in human molecular genetics and social science perspectives of socially constructed race, our study takes into account both genetic bio-ancestry...

China faces growing environmental problems as rapid economic growth comes at the cost of excessive resource consumption. Sustainable development can only be realized by reducing energy intensity. Although some general factors that influence energy intensity have been described, less information...

Water footprint is a research hotspot in the field of water resource. Gray water footprint is important in the assessment of environmental effects on water resource. In this short communication, a new gray water footprint assessment method was proposed as: WFgray(α, β, ϒ). Here α is an index...

One challenge in environmental liability law is to apportion the liability appropriately among multiple parties, when these multiple parties generate a single and non-separable damage. This paper provides a method of designing efficient apportionment rule in the presence of product market...
