BACKGROUND Shiftwork among health care workers impacts upon the safety and health of both employees and patients. AIMS To characterize shiftwork-related attitudes, behaviours, symptoms and coping strategies among health care workers, two validated questionnaires (the Standard Shiftwork Index and the Pressure Management Indicator) were used to identify factors predicting shiftwork adaptation. ...

We used a multiple baseline design to assess the effects of prompting and reinforcement to teach three pairs of adolescents with autism to use photographic activity schedules to cooperatively complete a multistep vocational task (e.g., cleaning a kitchen). Baseline data indicated that despite being competent schedule followers, participants did not coordinate their actions to complete the sched...

This paper investigates work ow systems in which the enactment and completion of activities have to satisfy a set of quantitative temporal constraints. Di erent activities are usually performed by autonomous agents, and the scheduling of activities by the enactment service has among its goals the minimization of communication and synchronization among the agents. The paper formally denes the no...

In MR Fingerprinting, the flip angles and repetition times are chosen according to a pseudorandom schedule. In previous work, we have shown that maximizing the discrimination between different tissue types by optimizing the acquisition schedule allows reductions in the number of measurements required. The ideal optimization algorithm for this application remains unknown, however. In this work w...

In this paper we present work to combine fixed priority scheduling with off-line schedule construction.It assumes a schedule has been constructed off-line for a set of tasks to meet their complex constraints.Our method takes the schedule and assigns the FPS attributes priority, offset, and period, to the tasks, such that their runtime FPS execution matches the off-line schedule.It does so by di...

This paper describes work in progress to enhance the performance of the Ground Processing Scheduling System (GPSS). The GPSS is a constraint-based scheduler that deals with three kinds of constraints: temporal, resource, and connguration. It starts with a complete schedule that may have some constraint violations (connicts) and gradually improves the schedule by reducing the violations. The obj...

Schedule delays commonly occur in construction projects and often result in delay and low productivity. Several studies have proposed different schedule delay analysis methodologies. By using asplanned and as-built schedules most studies have concentrated on calculating and identifying the delay events on project but have neglected the low productivity. Loss in productivity, which is a primary ...

Before any of the current “agile” development methods, Earned Value Management provided information for planning and controlling complex projects by measuring how much “value” was produced for a given cost in a period of time. One shortcoming of an agile development method is its inability to forecast the future cost and schedule of the project beyond the use of “yesterdays weather” metrics. Th...

The influence of four work-rest schedules (60-min shift-15-min break, 45-15, 30-15, 30-30) on acute effects of physical workload in the back and legs due to standing work was investigated in 12 poultry inspectors. Subjective discomfort in the legs and back, and swelling in the distal lower leg were significantly affected, with the 60-15 schedule leading to a higher postural load as compared wit...
