Sleep-related problems are often documented in children with Autism Spectrum Disorders (ASD). This study examined physical activity as a variable that might influence sleep quality in children with ASD. Ten children, ages 9-16 years, were asked to wear accelerometer devices for 7 days in order to track objective measures of activity and sleep quality. Parents of the children also completed the Child's Sleep Habits Questionnaire and maintained a daily sleep log while their child wore the device. This study demonstrated that though over half of the children were identified as having at least one sleep-related problem, their activity levels were significantly related to their sleep patterns. Specifically, the more physically active children had overall higher sleep quality.
Role Based Access Control (RBAC) is one of the most popular means for enforcing access control. One of the main reasons for this is that it is perceived as the least expensive configuration with respect to security administration. In this paper, we demonstrate that security administration is not always cheaper under RBAC when compared to the traditional Discretionary Access Control (DAC). If RBAC proves to be beneficial, organizations may choose to migrate from DAC to RBAC. There have been many algorithms developed to generate RBAC configurations from DAC configuration. Although these algorithms provide an RBAC configuration, the quality of the generated RBAC configuration could vary among different algorithms and DAC configurations. In this paper, we propose a decision support framework, which provides a basis for comparison among different potential RBAC derivations from DAC to determine the most desirable outcome with respect to the cost of security administration.
In this paper, we investigate ways that social media platforms can enhance the responsiveness of branches of local government that deal primarily in performing tasks on the behalf of citizens or interacting with them. More specifically, we utilize the Twitter platform (on the web and capable smartphones) to provide a two way communications channel between a local government system and citizens. Through such social media driven communication, citizens can submit requests for work to be completed, which could then be carried out by the local government. The goal of such a system is to enable the local government to increase responsiveness and gain efficiency in its manpower usage through optimized route planning and intelligent work dispatch.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
