PURPOSE Our objective in this study was to compare the quality of care provided under the Minnesota Senior Health Options (MSHO), a special program designed to serve dually eligible older persons, to care provided to controls who received fee-for-service Medicare and Medicaid managed care. DESIGN AND METHODS Two control groups were used; one was drawn from nonenrollees living in the same area...

A framework and analysis for a distributed sensor network based surveillance system is presented here. In a previous effort [1] we have presented methodologies for coordination and decision-making amongst sensors for tracking targets while in [2] we presented the results of endowing the sensor network with autonomy. Sensors monitor targets that crisscross a rectangular surveillance zone. When a...

background and purpose: equity in access to health care has become a desirable policy objective. therefore, accessibility to health care should be provided based on health needs rather than socio- demographic variables. this will lead to a better utilization of health care and improvement of equity in health. the aim of this paper is to examine the effects of family socio-economic status as an ...

Supporting mobile collaborative work over wide areas is challenging due to the limitations and unreliability of wide area wireless networks. However, variations in patterns of collaboration require different levels of timeliness and synchrony, and place different demands on groupware and its supporting technologies. In this paper, we argue that groupware supported by wide area mobile networks s...

Most previously proposed position based routing algorithms for wireless ad hoc networks were based on forwarding the actual message along multiple paths toward an area where destination is hopefully located. The significant communication overhead can be avoided if the routing strategy is changed. We propose that the source node issues several search 'tickets' (each ticket is a 'short' message c...

Routing optimization (RO) is an important support for Mobile IPv6 while performing handover. It can reduce the overhead of a home agent and make the traffic more fluent between MN and CN; however, Network Mobility (NEMO) in Mobile IPv6 lacks the capability of RO. In this paper, we propose an enhanced architecture by deploying Home Agents Location Registration Agents (HALRA) on cellular data swi...

This paper develops an extended version of MFCLSTP (Maximum Flow-Covering Location and service Start Time Problem, Tanaka 2011) by introducing multiple coverage levels based on the arrival time to a destination. The original MFCLSTP determines the locations of facilities and the start time of services of fixed duration to maximize coverage for flows on the way back home from work. In MFCLSTP, e...
