Harmonizing decentralized development of ICT solutions with centralized strategies, e.g., meant to favor reuse and optimization of resources, is a complex technical and organizational challenge. The problem, shared by virtually all the governments, is becoming a priority also for countries, such as Mozambique, that have started their ICT policy relatively recently and for which it is now eviden...

BACKGROUND In 2000, the USDHHS released Healthy People 2010 (HP2010), a series of disease prevention and health promotion objectives for the nation. Thirty-nine of these objectives were dedicated to injury prevention and six of these objectives related to adolescents, who were tracked through CDC's National Youth Risk Behavior Survey (YRBS). PURPOSE This paper uses national YRBS data from 199...

abstract We explore ways of constructing eecient delay-insensitive (DI) networks from a set of primitive DI elements by means of a case study. Several approaches that improve on recent designs of a modulo-N counter in the literature are illustrated. We obtain low constant latency, low constant response time, constant power consumption and optimal area-complexity designs for this circuit. For mo...

In recent years the development of eGovernment has increasingly gone from service provision to striving for an interoperable public sector, with Enterprise Architectures being an increasingly popular approach. However, a central issue is the coordination of work, due to differing perceptions among involved actors. This paper provides a deepened understanding of this by addressing the question o...

Information Technology (IT) now plays a fundamental role in most organizations. This increased responsibility and consequent impact in business performance leads to a higher demand and tighter control on IT Departments. To respond to these requirements, IT Departments have been implementing Service Management frameworks, with ITIL currently being the most popular. However, many ITIL projects fa...

People counting is a crucial and challenging problem in visual surveillance. Automatic monitoring of the number of people in public areas is important for safety control and urban planning. For this purpose many techniques and methods have been proposed. These techniques are not producing high performance and better accuracy for complicated scenes counting. Recently Foreground Extraction and Ex...

We undertook a telephone survey to examine perceived stress among 165 veterans with spinal cord injury (SCI) who received care from a Department of Veterans Affairs Medical Center. Measures included Perceived Stress Scale, Hassles Scale, Center for Epidemiologic Studies Depression Scale, Short-Form State-Trait Anxiety Inventory, Satisfaction with Life Scale, and Short-Form Interpersonal Support...

OBJECTIVE To compare patients with diabetes and new onset foot ulcers treated in Veterans Health Administration (VHA) and non-VHA settings. METHODS The treatment of patients with new onset diabetic foot ulcers was prospectively monitored in three VHA and three non-VHA hospitals and outpatient settings until ulcer healing, amputation, or death. RESULTS Of the 302 individuals enrolled in this...

OBJECTIVES To describe characteristics of services, providers, and patients in low-vision rehabilitation entities serving adults in the United States. METHODS Entities (excluding Veterans Affairs clinics) were identified through professional associations, Web searches, and a telephone survey to retina practices. A census obtained information on entity types, provider types, rehabilitation ser...

OBJECTIVES This study examines differences in the relationship between veteran status and men's trajectories of health conditions, activities of daily living limitations, and self-rated health. METHODS We use data on 12,631 men drawn from the 1992-2006 waves of the Health and Retirement Study to estimate growth curve models that examine differences in health trajectories between nonveterans a...
