The relationship between low socioeconomic status and higher levels of morbidity and mortality has been well-established in the literature. Researchers, however, rarely test the link between health improvements and social programs or economic policies designed to alleviate poverty. In this paper, we examine the health effects of the Earned Income Tax Credit (EITC), a broad-based income support ...

BACKGROUND AND AIM The public health impact of population-based mammography screening programs depends on high participation rates. Thus, monitoring participation rates, as well as understanding and considering the factors influencing attendance, is important. With the goal to acquire information on the appropriate level of intervention for increasing screening participation our study aimed to ...

As it is commonly understood, Urban neighborhoods play a significant role in developing urbansustainability as the smallest unit of city so that the formation and promotion of neighborhood identity, and focusingon social relationships would be in harmony with urban sustainability. It is believed that a dramatic change in spatialstructure of urban neighborhood include a decline in levels of poli...

BACKGROUND Dengue is an emerging health problem in several coastlines along the Red Sea. The objective of the present work is to elucidate spatial and temporal patterns of dengue transmission in Port Sudan. METHODS/FINDINGS A longitudinal study with three cross-sectional surveys was carried out in upper, middle and lower class neighborhoods, from November 2008 to October 2009. Monthly, entomo...

BACKGROUND Several studies have highlighted the importance of collective social factors for population health. One of the major challenges is an adequate definition of the spatial units of analysis which present properties potentially related to the target outcomes. Political and administrative divisions of urban areas are the most commonly used definition, although they suffer limitations in t...

Efforts to improve transportation choices and enhance accessibility at the neighborhood level have been hampered by a lack of practical planning tools. This paper identifies the factors that contribute to accessibility at the neighborhood level and explores different ways that planners can evaluate neighborhood accessibility. A gap between the data needed to describe important accessibility fac...

In this paper, we study social interactions between two populations of individuals living in a city. Agents consume land and benefit from intraand inter-group social interactions. We show that in equilibrium segregation arises: populations get separated in distinct spatial neighborhoods. Twoand three-district urban structures are characterized. For high population ratios or strong intergroup in...

Studies that examine spatial character-istics of urban unemployment are oftenbased on some simplistic and problematicmeasures of employment accessibility. Thispaper presents a refined methodologicalframework for measuring accessibility,which enables the researcher to (1) improvethe measurement by accounting for job com-petition among workers commuting by dif-...
