Landscape changes associated with urbanization can lead to many serious ecological and environmental problems. Quantifying the vertical structure of the urban landscape and its change is important to understand its social and ecological impacts, but previous studies mainly focus on urban horizontal expansion and its impacts on land cover/land use change. This papers focuses on the residential l...

There is a growing consensus among urban analysts that inner-city neighborhoods suffer from a lack of social capital. Because these areas do not have a strong social infrastructure in place to support successful revitalization efforts, urban policy recommendations now call for developing social capital in the worst-off parts of our cities. However, this consensus has been reached without any em...

Mosquito-vectored pathogens are responsible for devastating human diseases and are (re)emerging in many urban environments. Effective mosquito control in urban landscapes relies on improved understanding of the complex interactions between the ecological and social factors that define where mosquito populations can grow. We compared the density of mosquito habitat and pupae production across ec...

The main objective of this research is to eval...

A model is "any representation or concept that helps us to understand the world whenever common sense direct observations are inadequate." Common and observation often prove inadequate complexities of twenty-first-century cities. Thus, models abound in urban life governance. However, a not only tool for control but way defining situation. Framing city so as render it susceptible interpretation ...
