This study examined the effects of work schedule flexibility and the spillover of work stress to family life on the health of parents of adult children with serious mental illness (SMI). We compared 100 parents of adult children with SMI to 500 parents with nondisabled adult children using data from the Wisconsin Longitudinal Study. The detrimental impact on health of a lack of work flexibility...

This study prospectively examined the effects of a change of shift schedule from a fast forward-rotating schedule to a slowly backward-rotating one. The initial schedule had a forward rotation from mornings to afternoons to nights over 6 consecutive days, with 2 days on each shift followed by 4 days off before the next iteration of the cycle, whereas the new schedule had a slower backward rotat...

We present an operator for a propositional linear temporal logic over infinite schedules of iterated transactions, which, when applied to a formula, asserts that any schedule satisfying the formula is serializable. The resulting logic is suitable for specifying and verifying consistency properties of concurrent transaction management systems, that can be defined in terms of serializability, as ...

By Gerard Livaudais, MD, MPH Robert Unitan, MD Jay Post Frank Brennan, MD, a primary care physician, arrives at work at 7:00 am, to get a head start on the day. It’s a Monday and he knows his schedule will be full of patients wanting his care and attention. He enjoys being with his patients, but always needs more time. He diligently works through his schedule, focusing on one patient at a time....

This paper develops a model of activity and trip scheduling that combines three elements that have previously been investigated in isolation: the duration of activities, the time-of-day preference for activity participation and the effect of schedule delays on the valuation of activities. The model is in essence a GEV discrete choice model, describing individuals’ choice between alternative act...

We present the results of our work on applying genetic algorithms combined with a discrete event simulation to the problem of convoy scheduling. We show that this approach can automatically remove conflicts from a convoy schedule thereby providing to the human operator the ability to search for better solutions after an initial conflict free schedule is obtained. We demonstrate that it is feasi...

The main objective of this research was to conduct an assessment of ergonomic-related problems in oilrigs in a desert environment. A checklist, physical audit and medical records were used in the investigation. The results showed significant health, environment and work-related problems that could be attributed to ergonomic deficiencies in the work system of the oilrig. Some major ergonomic iss...

This paper describes a context-based dynamic messaging system, called ”Context Aware Messaging Service”. It uses schedule information and location information of the message addressee. According to the addressee’s communication context (schedule, location, and available media), the system selects the most suitable telephone number or e-mail address, and redirects each incoming message dynamical...

This paper proposes a technique to minimize the makespan of DAGs under energy constraints on multi-core processors that often need to operate under strict energy constraints. Most of the existing work aims to reduce energy subject to performance constraints. Thus, our work is in contrast to these techniques, and it is useful because one can encounter numerous energy-constraint scenarios in real...
