Individuals with Autism Spectrum Disorder (ASD) have a range of health, community, and social support needs across the lifespan that create age-specific challenges in navigating service sectors. In this study, we set out to identify the priority needs of individuals with ASD across the lifespan, and the factors that predict receiving priority services. Participants included 3,317 individuals wi...

OBJECTIVES The objectives of this study is to review the set of criteria of the Institute of Medicine (IOM) for priority-setting in research with addition of new criteria if necessary, and to develop and evaluate the reliability and validity of the final priority score. METHODS Based on the evaluation of 199 research topics, forty-five experts identified additional criteria for priority-setti...

In this paper, we model a call center as a preemptive-resume priority queue with time-varying arrival rates and two priority classes of customers. The low priority customers have a dynamic priority where they become high priority if their waiting-time in queue exceeds a given service-level time. The performance of the call center is measured by the mean number in system for the two customer cla...

Simultaneous Multithreading machines beneet from jobscheduling software that monitors how well coscheduled jobs share CPU resources, and coschedules jobs that interact well to make more eecient use of those resources. As a result, informed coscheduling can yield signiicant performance gains over naive schedulers. However, prior work has only focused only the situation where jobs have equal prio...

OBJECTIVE To describe and evaluate priority setting in the context of hospital priority setting and more specifically to evaluate the use of an appeals process. DESIGN Qualitative case study and evaluation using the ethical framework 'accountability for reasonableness'. SETTING The University Health Network (UHN), a network of three large urban teaching hospitals affiliated with the Univers...

This paper applies a matrix-analytic approach to analyze both the long-term and the short-term loss behaviors of a queue with space priority scheme. Five related performance measures are derived from conditional statistics, including the long-term highpriority and low-priority packet loss probabilities, and the three short-term measures — the average length of a critical period, the average len...

We model a call center as a preemptive-resume priority queue with time-varying arrival rates and two priority classes of customers. The low priority customers have a dynamic priority where they become high priority if their waitingtime exceeds a given service-level time. The performance of the call center is measured by the mean number in system for the two customer classes. A fluid approximati...

We ask the question, "for minimizing mean response time, which is preferable: one fast server of speed 1, or A; slow servers each of speed I/A:?" Our setting is the M/Gl/k system with two priority classes of customers, high priority and low priority, where G is a phase-type distribution. We find that multiple slow servers are often preferable — and we demonstrate exactly how many servers are pr...

BACKGROUND A medical emergency call is citizens' access to pre-hospital emergency care and ambulance services. Emergency medical dispatchers are gatekeepers to provision of pre-hospital resources and possibly hospital admissions. We explored causes for access, emergency priority levels, and temporal variation within seasons, weekdays, and time of day for emergency calls to the emergency medical...
