BACKGROUND This study compares differences in quality-adjusted life expectancy across the eight original National Occupational Research Agenda (NORA) industry sectors. METHODS Data from the 1997 to 2012 National Health Interview Survey (NHIS) were used to estimate quality-adjusted life years (QALYs) for all workers and by NORA sector. Differences in QALYs were calculated and translated into e...

This article reports on survey research (N = 1,418) aimed at examining whether parental expectations of maternal and child health (MCH) services are influenced by group characteristics (e.g., socioeconomic status [SES], ethnicity, at risk of poverty) and/or individual parenting context variables (e.g., received social support) in a context where these services are available to all. The findings...

We survey existing approaches to the formal verification of statecharts using model checking. Although the semantics and subset of statecharts used in each approach varies considerably, along with the model checkers and their specification languages, most approaches rely on translating the hierarchical structure into the flat representation of the input language of the model checker. This makes...

Recognition of machining features provides a bridge between Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) of machined parts. CAD produces part descriptions in terms of geometric entities or design features, which need not coincide with the manufacturing features needed by process planning activities. The CAD data must therefore be interpreted so as to generate part represen...
