Driven by rising income and urban population growth, China has experienced rapid urban expansion since the 1980s. Urbanization can have positive effects on the urban environment; however, improvement of urban environment quality, especially its divergence between relatively developed and undeveloped cities in China, is currently a rather rudimentary and subjective issue. This study analyzed urb...

This study applied logistic regression to model urban growth in the Atlanta Metropolitan Area of Georgia in a GIS environment and to discover the relationship between urban growth and the driving forces. Historical land use/cover data of Atlanta were extracted from the 1987 and 1997 Landsat TM images. Multi-resolution calibration of a series of logistic regression models was conducted from 50 m...

Currently, over 50% of the world’s population lives in urban areas. By 2050, this estimate is expected to be 70%. This urban growth, however, is not uniformly distributed around the world. The majority of it will occur in developing nations and create megacities whose populations exceed at least 10 million people. Not all urban areas, however, are growing. Some are actually losing populations b...

conclusions we confirm that in amol city and surrounding areas, the prevalence of true hcv infection is 0.05%, which is lower than that previously reported from iran. results the mean age of participants was 42.70 ± 17.10 years. of these participants, 57.2% (n = 3483) were male. anti-hcv antibody was positive in 12 individuals from which five were riba positive. three of these subjects were pcr...

BACKGROUND Improvements in child survival have been very poor in sub-Saharan Africa (SSA). Since the 1990 s, declines in child mortality have reversed in many countries in the region, while in others, they have either slowed or stalled, making it improbable that the target of reducing child mortality by two thirds by 2015 will be reached. This paper highlights the implications of urban populati...

Smallpox was probably the single most lethal disease in eighteenth-century Britain but was reduced to a minor cause of death by the mid-nineteenth century due to vaccination programmes post-1798.While the success of vaccination is unquestionable, it remains disputed to what extent the prophylactic precursor of vaccination, inoculation, reduced smallpox mortality in the eighteenth century. Small...

Around the world, particularly in North America and Australia, urban sprawl combined with low density suburban development has caused serious accessibility and mobility problems, especially for those who do not own a motor vehicle or have access to public transportation services. Sustainable urban and transportation development is seen crucial in solving transportation disadvantage problems in ...

In European cities, the rate of population growth has declined significantly, while the number of households has increased. This increase in the number of households is associated with an increase in space for housing. To date, the effects of both a declining population and decreasing household numbers remain unclear. In this paper, we analyse the relationship between population and household n...

The Philippines is 52% urbanized (ADB figure, the UN estimate is 59%), this percentage is expected to increase to 60% in 2010. The urban population grew very rapidly at an annual rate of close to 5% from 1960 to 1995, but has since slowed to approximately 3% annually. Given relatively slow economic development over the last three decades (relative to East Asian norms), the level of urbanization...
