OBJECTIVES We evaluated the spatial accessibility of large "chain" supermarkets in relation to neighborhood racial composition and poverty. METHODS We used a geographic information system to measure Manhattan block distance to the nearest supermarket for 869 neighborhoods (census tracts) in metropolitan Detroit. We constructed moving average spatial regression models to adjust for spatial aut...

In this study I investigate the associations of neighborhood socioeconomic and social environments with the health of Asian Americans living in both Asian ethnic neighborhoods and non-Asian neighborhoods. I use a sample of 1962 Asian Americans from the National Latino and Asian American Study (NLAAS, 2003-04). Three key findings emerge. First, absolute levels of socioeconomic and social resourc...

Many optimization problems of practical interest are computationally intractable. Therefore, a practical approach for solving such problems is to employ heuristic (approximation) algorithms that can find nearly optimal solutions within a reasonable amount of computation time. An improvement algorithm generally starts with a feasible solution and iteratively tries to obtain a better solution. Ne...

BACKGROUND The relationship between individual and neighborhood socioeconomic status (SES) and mortality rates in patients with nasopharyngeal carcinoma (NPC) is unknown. This population-based study aimed to examine the association between SES and survival of patients with NPC in Taiwan. MATERIALS AND METHODS A population-based follow-up study was conducted of 4691 patients diagnosed with NPC...

Although residential segregation is known to have declined for some racial groups in America, much less is known about change in the relative socioeconomic quality of the neighborhoods where different racial and ethnic groups live. Using census data for 1980-2010, we find that the neighborhoods where whites and minorities reside have become more alike in terms of neighborhood poverty and median...
