BACKGROUND The incidence and outcomes of out-of-hospital cardiac arrest vary widely across cities. It is unknown whether similar differences exist at the neighborhood level. OBJECTIVE To determine the extent to which neighborhoods have persistently high rates of cardiac arrest but low rates of bystander cardiopulmonary resuscitation (CPR). DESIGN Multilevel Poisson regression of 1108 cardia...

OBJECTIVE Recent work demonstrates the importance of in-store contents, yet most food access disparity research has focused on differences in store access, rather than the foods they carry. This study examined in-store shelf space of key foods to test whether other types of stores might offset the relative lack of supermarkets in African-American neighborhoods. METHODS New Orleans census trac...

Wilson (1987) and others argue that poor neighborhoods lack important organizational resources the middle class takes for granted, such as childcare centers, grocery stores and pharmacies. However, this approach does not distinguish poor neighborhoods from segregated neighborhoods, ignores immigration and neglects city differences. Using Department of Commerce and 2000 Census data for zip codes...

This research aims to identify the accessibility of entire population, especially slum population existing healthcare facilities (HCF) as well neighborhoods having low geographic accessibility, and finally, provide an analytical model for people living in areas that are outside coverage range across study area. Spatial data has been collected used based on road network, elevation, location HCF,...

We investigate the problem of balancing assembly lines with heterogeneous workers while considering job rotation schedules. This problem typically occurs in assembly lines in sheltered work centers for disabled. We propose a hybrid algorithm that uses a Mixed Integer Programming (MIP) to select appropriate schedules from a pool of heuristically constructed solutions. A local search based on MIP...

We examine the impact of neighborhood socioeconomic conditions and "built environments" on obesity and overweight prevalence among U.S. children and adolescents using the 2007 National Survey of Children's Health. The odds of a child's being obese or overweight were 20-60 percent higher among children in neighborhoods with the most unfavorable social conditions such as unsafe surroundings; poor...

Neighborhoods where blacks and whites live in integrated settings alongside Hispanics and Asians represent a new phenomenon in the United States. These "global neighborhoods" have previously been identified in the nation's most diverse metropolitan centers. This study examines the full range of metropolitan areas to ask whether similar processes are occurring in other parts of the country. Is t...

Neighborhood characteristics have been associated with both depression and diabetes, but to date little attention has been paid to whether the association between depression and diabetes varies across different types of neighborhoods. This prospective study examined the relationship between depression, neighborhood deprivation, and risk of type 2 diabetes among 336,340 adults from a national-re...

Written by a former mayor of Seattle, this Article describes the “smart growth” movement as a way to sustain the livability of large urban centers in the twenty-first strategy. It describes some of the problems facing urban areas experiencing population growth, namely traffic, rising housing prices and a scarcity of open space. The ”smart growth” movement seeks to address these problems in a co...
