This paper presents the research methodology that applied existing data to the study of environmental and health inequalities in Accra, Ghana, and Sao Paulo, Brazil. After an introductory section, the paper considers why more research in this area is necessary and the reasons why information on cities in the South is lacking. The third section describes the aims and methods of the study by 1)...

Urban land cover is one of the fastest global growing land cover types which permanently alters land surface properties and atmospheric interactions, often initiating an urban heat island effect. Urbanisation comprises a number of land cover changes within metropolitan regions. However, these complexities have been somewhat neglected in temperature analysis studies of the urban heat island effe...

Urban built-up area information is required by various applications. However, urban built-up area extraction using moderate resolution satellite data, such as Landsat series data, is still a challenging task due to significant intra-urban heterogeneity and spectral confusion with other land cover types. In this paper, a new method that combines spectral information and multivariate texture is p...

Urban air quality, and its variability in space and time, is a critical issue for human exposure and health related studies. In this work, we investigated the intra-urban distribution of SO2, NOx, NO2, Benzene, Toluene, and Xylenes in ambient air in one of the world’s most polluted cities, Lanzhou, China. Measurements were contemporarily carried out at forty locations in four seasonal campaigns...

Municipalities need accurate and updated inventories of urban vegetation in order to manage green resources and estimate the profit of urban forestry activities. Earlier studies using high resolution satellite images have shown that automatic tree detection in urban areas using traditional classification techniques remains a very difficult task. This is mainly due to intra-crown spectral variat...

In 2008, the global urban population surpassed the rural population and by 2050 more than 6 billion will be living in urban centres. A growing body of research has reported on poor health outcomes among the urban poor but not much is known about HIV prevalence among this group. A survey of nearly 3000 men and women was conducted in two Nairobi slums in Kenya between 2006 and 2007, where respond...

A nurse residency program's best practice recommendations are presented within this article and are organized around three processes: establishing the program infrastructure, creating a multistaged evidence-based program, and sustaining the program through appropriate evaluation and dissemination of results. These recommendations represent lessons learned and key findings derived from a team of...

It is a great pleasure for me to attend the Fourth Annual Forum on City Informatization in the Asian-Pacific Region while having this opportunity to exchange views with the distinguished guests. IT Promotes Development, the theme of the annual forum which fully reveals the significance of sustainable development of informatization and its role in the development. This is a theme which attracts ...
