Children with autism spectrum disorder engage in restricted and repetitive behavior. Some of these children problem behavior when rituals are interrupted. The purpose the current study was to evaluate use trial-based functional analysis assess related ritual interruption treat using communication training plus a multiple schedule. We found that correctly identified presence function treatment e...

PURPOSE To assess the impact of treatment interruption on the potential gain in locoregional control obtained with accelerated radiotherapy (RT) compared with conventionally fractionated RT in patients with oropharyngeal carcinomas. METHODS AND MATERIALS 152 patients treated with radical RT for oropharyngeal carcinomas between 1979 and 1996 were retrospectively analyzed. According to the Amer...

On the basis of theoretical assumptions regarding resource gain and loss (S. E. Hobfoll, 1998), the authors used a longitudinal study to examine effects of vacation on well-being and performance-related outcomes. University employees (N = 221) completed measures of well-being (health complaints and burnout) and performance-related outcomes (self-reported task performance and effort expenditure)...

Driven from real-life applications, this work aims to cope with the scheduling problem of automotive glass manufacturing systems, that is characterized as a two-stage flow-shop small batches, inevitable setup time for different product changeover at first stage, and un-interruption requirement second stage. To best knowledge authors, there no report on topic other research groups. Our previous ...

STUDY OBJECTIVES This analysis examined associations between the salivary dim light melatonin onset (DLMO) phase and self-selected sleep/ wake schedules in groups of children and adolescents during summer vacation and during the school year to determine the degree to which sleep/wake patterns can estimate salivary DLMO phase. DESIGN AND SETTING Participants slept at home on self-selected sche...

In this paper, we investigate the power management of mobile devices, using a variant of an M/G/1 queue with probabilistic inhomogeneous multiple vacations and generalized service process. Under the vacation scheme, at the end of a vacation the server goes on another vacation, with a different probability distribution, if during the previous vacation there have been no arrivals. The modified va...

We consider a single-server vacation queueing system that operates in the following manner. When the server returns from a vacation, it observes the following rule. If there is at least one customer in the system, the server commences service and serves exhaustively before taking another vacation. If the server finds the system empty, it waits a fixed time c. At the expiration of this time, the...

Chronic incomplete recovery from work may have serious consequences in terms of ill-health. Although vacation is one of the most powerful manipulations of recovery in a field context, up to now only few researchers have addressed the impact of vacation on recovery from work. The aim of the current contribution is to present an overview of previous and current findings in this area and to give s...

This paper studies the operating characteristics of an MX/Hk/1 queueing system under multiple vacation policy. It is assumed that the server goes for vacation as soon as the system becomes empty. When he returns from a vacation and there is one or more customers waiting in the queue, he serves these customers until the system becomes empty again, otherwise goes for another vacation. The brea...
