healthy hire effect (hhe) is considered as an epidemiological phenomenon, complicating the assessment of a true cause - effect relationship between occupational exposure and health status of workers. the current study was aimed at identification and elimination of hhe in the risk assessment of arterial hypertension (ah) in coal miners. overall, 1553 miners, working in west siberia, were enrolle...

Abstract Convex clustering has received recently an increased interest as a valuable method for unsupervised learning. Unlike conventional methods such k-means, its formulation corresponds to solving convex optimization problem and hence, alleviates initialization local minima problems. However, while several algorithms have been proposed solve formulations, including those based on the alterna...

Worker policing, wherein social insect workers prevent their sisters from reproducing by eating worker-laid eggs, is recognized as a textbook example of kin selection in action. However, the evolutionary basis of policing was recently challenged in a study that suggested that police-workers remove worker-laid eggs not because rearing workers' sons reduces worker fitness, but merely because work...

Objectives: Mental health organizations are strongly encouraged to implement empirically supported treatments (ESTs), however little is known about their working environments. The present study investigated how provider demographics, workplace environment and whether ESTs were used affected the worker morale. Methods: Front-line workers (N = 1,273) from 55 different programs in a single, large ...

Social evolution in honey bees has produced strong queen-worker dimorphism for plastic traits that depend on larval nutrition. The honey bee developmental programme includes both larval components that determine plastic growth responses to larval nutrition and nurse components that regulate larval nutrition. We studied how these two components contribute to variation in worker and queen body si...

Work flow policies are shown to induce a change in average between-workers variability (worker heterogeneity) and within-worker variability in performance times. In a laboratory experiment, the authors measured the levels of worker heterogeneity and within-worker variability under an individual performance condition, a work sharing condition, and a fixed assignment condition. The work sharing p...

With the rapid development of Internet things (IoT) and computer vision (CV), application combining IoT platform CV technology to monitor worker safety has attracted more attention in field industrial information. Worker identification is a prerequisite for management production, helmet can not only protect worker’s head from accidental injuries but also help identify work types workers through...
