This study investigated land use changes, and their ecological effects in Wuhan (1987-2005). Remote Sensing techniques extracted land use data, whilst the spatial analyst software, Fragstats quantified ecological metrics at both landscape and class levels. The results showed increased urban and agricultural land uses (1987-2005); with urban land increasing more than 250 percent. This was largel...

An inverted-U relationship between GDP per capita and three urban transport-related emissions is tested (using data from 84 cities). Per capita urban transport-related emissions of CO, VHC, and NOx increase and then decline at observed income levels—a result driven by a similar inverted-U relationship between income and emissions technology (i.e., emissions per passengerkm). However, for urban ...

Using transnational terrorism data from 1980 to 2000, this study empirically examines the relationships between frequency of participation in transnational terrorism acts and economic development and education improvement. We find an inverse U-shaped association between the frequency of various nationals acting as perpetrators in transnational terrorism acts and per capita income in their respe...

Megacities concentrate large amounts of people, absorb a large quantity of resources and generate vast amounts of waste and sewage, thereby contributing considerably to the use of the environment as a sink. The quantity of resources consumed and urban residues produced per capita tend to rise steadily with increased per capita income. Proper management of municipal solid waste is critical to th...

OBJECTIVES Swiss health care is relatively costly. In order better to understand the drivers of spending, this study analyses geographic variation in per capita consultation costs for ambulatory care. METHODS Small area and longitudinal analysis of costs of ambulatory services covered by compulsory health insurance, 2003-07. RESULTS The results show considerable geographic variation in per ...

Considerable portion of housing sector from gross domestic product indicates relationship between housing sector and macroeconomics. This paper focuses on consumption demand of housing and variables that can affect it and represents a theoretical framework for changes of housing prices regarding variables such as income per capita, liquidity and land per capita, the present paper studies effect...

urban green spaces are one of the most important services in modern cities and form a set of urban sustainable development factors which receive considerable attention from urban planners. this paper explains how land use can be optimally allocated to urban public green spaces. in this study, some of the factors influencing urban green spaces in a period from 1373 to 1384 were studied. moreover...

Meta-analysis combines results from multiple longitudinal studies to describe life course variation by age and sex for quantity of drinking per typical occasion (20 studies) and frequency of drinking during one month (27 studies). There is cross-study heterogeneity for the Time 1 means of the drinking variables blocking for age and sex. Age distributions for the Time 1 means are similar by gend...
