We describe an approach to developing next generation health information portals. This prototype portal was developed to address two complementary goals (1) design and create a site where people can explore potential relationships between selected health-related behaviors, policies, and demographic data (2) explore semantic web technologies and linked data(More)
We describe our semantically-enabled approach to integrate, visualize, and explore health data. The project was conducted in a trans-disciplinary setting with population and behavioral scientists, social network scientists, data analysts, and computer scientists focused on making complex health-related data available, accessible, and understandable. One of(More)
PerMIS'07 will be the seventh in the series that started in 2000, targeted at defining measures and methodologies of evaluating performance of intelligent systems. The workshop has proved to be an excellent forum for discussions and partnerships , dissemination of ideas, and future collaborations in an informal setting. FOREWORD The 2008 Performance Metrics(More)
—Increasingly, experts and interested laypeople are turning to the explosion of online data to form and explore hypotheses about relationships between public health intervention strategies and their possible impacts. We have engaged in a multi-year collaboration to use and design semantic techniques and tools to support the current and next generation of(More)
OBJECTIVE To [1] compare the frequency and severity of ultrasound (US) features in people with normal knees (controls), knee pain (KP), asymptomatic radiographic OA (ROA), and symptomatic OA (SROA), [2] examine relationships between US features, pain and radiographic severity, [3] explore the relationship between change in pain and US features over a(More)
This study reports the results of a trial of essential fatty acid (EFA) supplementation in psychiatric patients (predominantly schizophrenics) with movement disorders. Evidence of EFA deficiency in these patients was observed. The antidyskinetic effect of EFA supplementation was marginally significant but not clinically important. However, active treatment(More)
OBJECTIVE In an effort to standardize behavioral measures and their data representation, the present study develops a methodology for incorporating measures found in the National Cancer Institute's (NCI) grid-enabled measures (GEM) portal, a repository for behavioral and social measures, into the cancer data standards registry and repository (caDSR).

6-Hydroxydopamine (6-OHDA) given i.v. in a dose of 150 mg/kg to adult male Sprague-Dawley rats produces at 24 h a complete depletion of median eminence (ME) and neurointermediate lobe (NIL) catecholamines (CA), as judged by Falck-Hillarp fluorescence histochemistry, leaving the remainder of the hypothalamus substantially unaltered. Restoration of a normal(More)
In situ edaphic factors affecting seed germination and seedling emergence of three framework species of Acacia were investigated with the intent of developing fundamental and scalable restoration capacity for Arabian dryland restoration. Direct seeding represents the most efficient means to restore vegetation at the landscape scale and this study provides(More)
This paper uses spatial economic data from four small English towns to measure the strength of economic integration between town and hinterland and to estimate the magnitude of town–hinterland spill-over effects. Following estimation of local integration indicators and inter-locale flows, sub-regional social accounting matrices (SAMs) are developed to(More)
