INTRODUCTION The association between levels of physical activity and perceived and objectively measured proximity to physical activity resources is unclear. Clarification is important so that future programs can intervene upon the measure with the greatest association. We examined correlations between perceived and objectively measured proximity to physical activity resources and then examined ...

Co-simulation platforms are necessary to study the interactions of complex systems integrated in future smart grids. The Virtual Grid Integration Laboratory (VirGIL) is a modular co-simulation platform designed to study interactions between demand response strategies, building comfort, communication networks, and power system operation. This paper presents the coupling of power systems, buildin...

OBJECTIVES Using data from a large cohort of adults aged 45 to 84 years-old, we investigated whether availability of recreational resources is related to physical activity levels. METHODS Data from a multiethnic sample of 2723 adult residents of New York City, NY; Baltimore, Md; and Forsyth County, NC, were linked to data on locations of recreational resources. We measured the availability (d...

PURPOSE To investigate factors of low-income neighborhoods and households on physical activity with a sample of adolescents from low-income neighborhoods. METHODS Middle-school-aged youth (n = 74) from a low-income neighborhood completed self-report surveys. Measures include vigorous exercise frequency, neighborhood hazards, after-school time demands, availability of facilities, quality of fa...

For better application-level controls on mashups, we advocate extending the Single Origin Policy and associated primitives to support a cooperative model that allows applications to express explicit sharing policies over browser, Javascript, and physical resources. First, we introduce an isolation model for content loading that is more complete than those of surveyed browser proposals. Second, ...

Physical separation is one of the key technologies in the field of resources recycling for concentrating targeted component(s) and could create an environment friendly recycling process because of their relatively low energy consumption and low cost required. Physical separation process involves two kinds of stages, one is comminution for achieving the liberation of targeted component(s) and th...

Researchers in physical medicine and rehabilitation require access to information regarding possible interventions and programs, available services and technology, research (published, unpublished and in progress), statistics on incidence, prevalence and expected recovery, and funding sources. This paper provides an overview to the most readily available sources of information, including 16 abs...

in fact, health strategists and policymakers contribute to the effectiveness and efficiency of planning, providing and evaluating health care, and the use of various capabilities of itc. the evidence for this claim includes: e-government, e-development, e-commerce, e-assurance and the same issues which are pursued in high levels of govemment’s legislative and executive bodies. e-health is consi...
