We investigated whether intelligent advanced warnings of the end of green traffic signals help drivers negotiate the dilemma zone (DZ) at signalized intersections and sought to identify behavioral mechanisms for any warning-related benefits. ⋯ Applications include performance models of how drivers use end-of-green warnings, control algorithms and warning displays for intelligent intersections, and statistical methodology in human factors research.

The impact of a decision support tool designed to embed contextual mission factors was investigated. Contextual information may enable operators to infer the appropriateness of data underlying the automation's algorithm. ⋯ Designers may mitigate some of the performance decrements experienced with imperfect automation by providing operators with interfaces that display contextual information, that is, the state of factors that affect the reliability of the automation's recommendation.

Randomized Controlled Trial
Evaluation of a configural vital signs display for intensive care unit nurses.
The objective was to evaluate a configural vital signs (CVS) display designed to support rapid detection and identification of physiological deterioration by graphically presenting patient vital signs data. ⋯ Although many studies, including this one, support the use of configural displays, the vast majority of ICU monitoring displays still present clinical data in numerical format. The introduction of configural displays in clinical monitoring has potential to improve patient safety.

Randomized Controlled Trial
The effects of visual and cognitive distractions on operational and tactical driving behaviors.
This study tested the effects of two fundamental forms of distraction, including visual-manual and cognitive-audio distraction, with comparison under both operational and tactical driving. Strategic control remains for future study. ⋯ Findings support the need to assess the impacts of in-vehicle distraction on different levels of driving control. Future study should investigate driver distraction under strategic control.

Multicenter Study
Musculoskeletal pain and reported workplace assault: a prospective study of clinical staff in nursing homes.
This study examined prospectively the effect of workplace violence on musculoskeletal symptoms among nursing home workers. ⋯ More effective assault prevention would protect and support the workforce needed to care for our increasing elderly and disabled population.
