Neighborhoods often resist public transit expansion for fears that it will increase crime by attracting transient populations and prospecting criminals. On the other hand, transit may reduce crime by altering economic development and other positive features of neighborhoods. Studies examining public transit and crime have either been cross sectional or examined the impact of public transit expa...

A LTHOUGH THE PATIENT PROTECTION AND Affordable Care Act (ACA) was passed in 2010, the major expansion of health insurance promulgated by the bill does not occur until 2014. At that time an estimated 23 million uninsured Americans with incomes below 133% of the federal poverty level will gain Medicaid. An additional 17 million persons will be eligible for subsidized coverage under a health insu...

This article illuminates the principal mechanisms that increase the risk of STIs for female sex workers in China. It draws primarily on my 26 months of ethnographic fieldwork (2006-2009) in red-light district neighborhoods in Haikou that have become centers of internal migration in post-reform southern China. Chinese sex workers here challenge dominant representations of them as illegal, immora...

BACKGROUND The concept of walkable neighborhoods is increasingly important in physical activity research and intervention. However, limited theoretical understanding and measurable definitions remain a challenge. METHODS This paper reviews theories defining neighborhoods and offers an empirical approach to identify measurable attributes and thresholds of walkable neighborhoods. Bivariate and ...

Predictors of repeated violent delinquency across ages 13-19 were investigated in a longitudinal sample of 420 urban adolescent males living in high- compared to low-socioeconomic status (SES) neighborhoods. Adolescents in high-SES neighborhoods were significantly less likely than their counterparts in low-SES neighborhoods to engage in serious and violent delinquency. Results indicated that ri...

Within federally qualified health centers serving low-income, African American audiences, participatory approaches to system changes were organized through multidisciplinary committees that (a) drew on evidence-based guidelines, (b) guided system changes including the requirement of documenting smoking status and readiness to quit in encounter forms, (c) tested and refined practice improvements...

Clustering algorithms are often used to find groups relevant in a specific context; however, they are not informed about this context. We present a simple algorithm, HOODS, which identifies context-specific neighborhoods of entities from a similarity matrix and a list of entities specifying the context. We illustrate its applicability by finding disease-specific neighborhoods of functionally as...

The fundamental organizing elements of the New Urbanism are the neighborhood, the district and the corridor. Neighborhoods are urbanized areas with a balanced mix of human activity; districts are areas dominated by a single activity; corridors are connectors and separators of neighborhoods and districts. A single neighborhood standing free in the landscape is a village. Cities and towns are mad...

This paper uses restricted census microdata to examine housing values and rents for neighborhoods in the United States where power plants were opened during the 1990s. Compared to neighborhoods with similar housing and demographic characteristics, neighborhoods within two miles of plants experienced 3-7 percent decreases in housing values and rents with some evidence of larger decreases within ...

An increasing number of evidences show that genes are not distributed randomly across eukaryotic chromosomes, but rather in functional neighborhoods. Nevertheless, the driving force that originated and maintains such neighborhoods is still a matter of controversy. We present the first detailed multispecies cartography of genome regions enriched in genes with related functions and study the evol...
