Complexity science suggests that our current health care delivery system acts as a complex adaptive system (CAS). Such systems represent a dynamic and flexible network of individuals who can coevolve with their ever changing environment. The CAS performance fluctuates and its members' interactions continuously change over time in response to the stress generated by its surrounding environment. ...

This paper is based on the results from the project PROTEUS sponsored by the French Ministry of Economy, Finance and Industry and the Federal Ministry of Education and Research of Germany under the label of European Commission Initiative ITEA. It presents the architecture and the basic concepts of an integration platform, which constitutes the framework of systems implementing the tasks dedicat...

This paper presents a new behavior based covert channel utilizing the database update mechanism of anti-virus software. It is highly covert due to unattended, frequent, automatic signature database update operations performed by the software. The design of the covert channel is described; its properties are discussed and demonstrated by a reference implementation. This paper uses these points t...

Asian American (ASA) children experience high rates of mental health problems. Although there is a pressing need to utilize population approaches, emerging frameworks from the fields of public and population health have not been applied to ASA children. This paper addresses this gap by first discussing applications of the National Prevention Strategy (NPS), a population strategy developed from ...

In this paper we present a modular sensor data fusion functional architecture, tailored for development of automotive active safety systems. The purpose of the fusion system is to provide active safety applications with accurate knowledge regarding the environment surrounding the vehicle. Our proposed functional architecture is designed in such way that the fusion system is easy to maintain, up...

We address unsolved problems of unfolding polyhedra in a new context, focusing on special convex patches—disklike polyhedral subsets of the surface of a convex polyhedron. One long-unsolved problem is edge-unfolding prismatoids. We show that several natural strategies for unfolding a prismatoid can fail, but obtain a positive result for “petal unfolding” topless prismatoids, which can be viewed...

PURPOSE This study investigated the improvement of interprofessional practice in primary care by performing the first three steps of the implementation model described by Grol et al. This article describes the targets for improvement in a setting for children with complex care needs (step 1), the identification of barriers and facilitators influencing interprofessional practice (step 2), and th...

States continue to experiment with ways of improving health and human service use by people with complex needs. Such efforts have often sought to increase individual and family control over services as well as to enhance coordination among providers. Paths to achieving these goals are not well understood. This study draws on two previously distinct conceptual frameworks to examine how 71 public...

Reuse is a powerful method for improving system performance. In this paper, we examine functional decomposition for improving data reuse and, therefore, overall query execution performance in the context of data analysis applications. Additionally, we look at the performance effects of using various projection primitives that make it possible to transform intermediate results generated during t...
