BACKGROUND Urban sprawl has the potential to influence cancer mortality via direct and indirect effects on obesity, access to health services, physical activity, transportation choices and other correlates of sprawl and urbanization. METHODS This paper presents a cross-sectional analysis of associations between urban sprawl and cancer mortality in urban and suburban counties of the United Sta...

This paper aims to analyse urban mobility patterns and consequent impacts on energy and environment in India. We investigate the quantity of energy use in 23 metropolitan regions for the period 1981–2005 and present empirical results obtained using national and urban data sets. It explores the underlying relationship among three dependent variables—energy intensity, type of mode and passenger k...

The traditional categorization of crime types relies on a hierarchical structure, from high-level categories to lower-level subtypes. This tree-based classification treats as mutually independent when they do not branch the same higher-level category, therefore lacking inter-category semantic relations. issue then extends over distribution analysis urban regions, often reporting statistics base...

Large di erences in hourly compensation exist between the natives (urban hukou holders) and rural to urban migrants of the Chinese cities, a third of which cannot be explained by any variation in observable characteristics. This paper attempts to explain the di erences using a Tiebout-esque political economy model of migration in which rents are appropriated from the migrants by the rent-seekin...

Urban change detection of high resolution images is very difficult due to the complex nature of the urban environments. A robust approach is proposed in this paper for urban change detection of high resolution images, which is based on the integration of objectspecific features. To model the contextual information and improve the interclass variability between different classes, homogeneous reg...

We explore the simulation of urban growth using complex systems theory and cellular automata (CA). The SLEUTH urban CA model was applied to two different metropolitan areas in Portugal, with the purposes of allowing a comparative analysis, of using the past to understand the dynamics of the regions under study, and of learning how to adapt the model to local characteristics in the simulation of...

Urban landscapes are the everyday environment for the majority of the global population, and almost 80 % of the Europeans live in urban areas. The continuous growth in the number and size of urban areas along with an increasing demand on resources and energy poses great challenges for ensuring human welfare in cities while preventing an increasing loss of biodiversity. The understanding of how ...

During the period 1971–2000, studies from different parts of India reported a 10-fold increase in the incidence of diabetes in urban India (from 1.2% in 1971 to 12.1% in 2000).5-7 In 2003–2005, a national survey was conducted in persons of age greater than or equal to 15 years, in which self-reported prevalence of diabetes was 7.3% in the urban areas and 3.2% in periurban slum areas. The preval...
