Older adults living in high-deprivation areas walk less than those living in low-deprivation areas. Previous research has shown that older adults' outdoor walking levels are related to the neighbourhood built environment. This study examines inequalities in perceived built environment attributes (i.e., safety, pedestrian infrastructure and aesthetics) and their possible influences on disparitie...

Effective outdoor educators need to understand the developmental characteristics of students to best tailor programs to capitalize upon their capabilities. To the extent that learning is a primary objective of outdoor education programs, understanding our students’ intellectual processes, specifically, can enhance our effectiveness in achieving this goal. This article presents several framework...

Indoor parasitic cellular systems reuse the same frequencies as outdoor cellular (macrocellular) systems to provide wireless communications inside a building or campus. This paper provides a simulation strategy to determine future channel availability that is possible between in-building and outdoor cellular systems that share the same radio spectrum. Capacity that is currently available inside...

BACKGROUND Traffic noise has been associated with prevalence of hypertension, but reports are inconsistent for blood pressure (BP). To ascertain noise effects and to disentangle them from those suspected to be from traffic-related air pollution, it may be essential to estimate people's noise exposure indoors in bedrooms. OBJECTIVES We analyzed associations between long-term exposure to indoor...

BACKGROUND Detailed spatial location information is important in accurately estimating personal exposure to air pollution. Global Position System (GPS) has been widely used in tracking personal paths and activities. Previous researchers have developed time-activity classification models based on GPS data, most of them were developed for specific regions. An adaptive model for time-location clas...

BACKGROUND Community participation is often restricted after stroke, due to reduced confidence and outdoor mobility. Australian clinical guidelines recommend that specific evidence-based interventions be delivered to target these restrictions, such as multiple escorted outdoor journeys. The aim of this study was to describe post-inpatient outdoor mobility and transport training delivered to str...

OBJECTIVES To identify risk factors for indoor and outdoor falls. DESIGN Prospective cohort study. SETTING The MOBILIZE Boston Study, a study of falls etiology in community-dwelling older individuals. PARTICIPANTS Seven hundred sixty-five women and men, mainly aged 70 and older, from randomly sampled households in the Boston, Massachusetts, area. MEASUREMENTS Baseline data were collecte...

Cutaneous malignant melanoma (CMM) has been increasing at a steady exponential rate in fair-skinned, indoor workers since before 1940. A paradox exists between indoor and outdoor workers because indoor workers get three to nine times less solar UV (290-400 nm) exposure than outdoor workers get, yet only indoor workers have an increasing incidence of CMM. Thus, another "factor(s)" is/are involve...

OBJECTIVE To assess the relationship of near, midworking distance, and outdoor activities with prevalence of myopia in school-aged children. DESIGN Cross-sectional study of 2 age samples from 51 Sydney schools, selected using a random cluster design. PARTICIPANTS One thousand seven hundred sixty-five 6-year-olds (year 1) and 2367 12-year-olds (year 7) participated in the Sydney Myopia Study...
