NIOSH researchers conducted a study to compare seat designs on underground coal mine haulage vehicles. The objective of the study was to support prior findings that NIOSH-designed seats, which incorporated ergonomic design features (e.g., viscoelastic foam padding and low-back support), are improved designs. Based on measured levels of vehicle jarring/jolting and perceived discomfort, researche...

let $r$ be a right artinian ring or a perfect commutative‎‎ring‎. ‎let $m$ be a noncosingular self-generator $sum$-lifting‎‎module‎. ‎then $m$ has a direct decomposition $m=oplus_{iin i} m_i$‎,‎where each $m_i$ is noetherian quasi-projective and each‎‎endomorphism ring $end(m_i)$ is local‎.

The National Institute o f Occupational Safety and Health (NIOSH) is dedicated to achieving "safety and health at work for all people — through research and prevention." An important procedure in pursuing this goal is the NIOSH surveillance studies where the number o f injuries are monitored according to demographic, employment, and injury characteristics. These numeric data are then used to id...

INTRODUCTION Large programmatic grants advance the missions of funding agencies or organizations. This article describes the programmatic impact of using "hierarchical" logic models in two Centers funded by the National Institute of Occupational Safety and Health (NIOSH) that were designed to achieve NIOSH goals. Such models are supportive of priority setting, policy implementation, and effecti...
