INTRODUCTION This study has been performed to determine the influence of rotating shift work on physical working capacity of Tunisian nurses and to design recommendations to managers so that they implement effective preventive measures. METHODS It is a cross-sectional design using a standardized questionnaire and many physical capacity tests on a representative sample of 1181 nurses and nursi...

OBJECTIVE Physicians' personal health habits are associated with their counseling habits regarding physical activity. We sought to examine physicians' own barriers to a healthy lifestyle by level of training and gender. METHODS Physicians at a major teaching hospital were surveyed regarding their lifestyle habits and barriers to healthy habits. The frequency of reported barriers was examined ...

Mixed Criticality systems require a difficult compromise to be drawn between efficient system utilisation and sufficient separation of critical components. In addition to these challenges, hardware platforms are becoming increasingly multicore in nature bringing up additional scheduling issues. Previous publications have met these challenges by suggesting a Cyclic Executive based approach for M...

The unhealthy symptoms and many deleterious consequences of shift work can be explained by a mismatch between the work-sleep schedule and the internal circadian rhythms. This mismatch occurs because the 24-h zeitgebers, such as the natural light-dark cycle, keep the circadian rhythms from phase shifting to align with the night-work, day-sleep schedule. This is a review of studies in which the s...

OBJECTIVE To carry out a survey data collection from health care workers in Brazil, Croatia, Poland, Ukraine and the USA with two primary goals: (1) to provide information about which aspects of well-being are most likely to need attention when shiftwork management solutions are being developed, and (2) to explore whether nations are likely to differ with respect to the impacts of night work on...

This final rule makes several changes affecting Medicare Part B payment. The changes include: implementation of resource-based malpractice insurance relative value units (RVUs); refinement of resource-based practice expense RVUs; payment for physician pathology and independent laboratory services; discontinuous anesthesia time; diagnostic tests; prostate screening; use of CPT modifier -25; qual...

We consider the problem of finding a schedule for n identical malleable tasks on p identical processors with minimal completion time. This problem arises while using the branch & bound or the divide & conquer strategy to solve a problem on a parallel system. If nothing is known about the sub-problems, then they are assumed to be identical. We assume that the execution time decreases with the nu...

We propose a new scheme for streaming media systems that combines Adaptive Media Playout (AMP) with ratedistortion optimized packet transmission. AMP, the clientcontrolled, adaptive modification of the media playout rate, allows us to flexibly adjust the playout deadlines of individual packets, and can therefore reduce reconstruction distortion. This added flexibility incurs a subjective cost, ...

All-to-All Personalized Communication (AAPC) requires each of the N nodes in a network to send a unique message to each of the other N ? 1 nodes. In this paper, we study the problem of scheduling AAPC in WDM rings with K wavelengths and T transmitter-receiver pairs per node. We rst determine the theoretical lower bound on the schedule length in a unidirectional ring with negligible tuning delay...
