The paper aims to investigate land use change at the county level in Beijing-Tianjin-Hebei Metropolitan Region. Three land use patterns are identified by assessing the urban-rural linkages: urban, peri-urban and periphery areas. Empirical analysis shows that land use change in the urban areas is faster than that in the peri-urban and periphery areas. Economic conditions are significant to the l...

BACKGROUND A decline in HIV incidence has been reported in Zambia and a number of other sub-Saharan countries. The trend of HIV prevalence among young people is a good marker of HIV incidence. In this study, different data sources are used to examine geographical and sub-population group differentials in HIV prevalence trends among men and women aged 15-24 years in Zambia. DESIGN AND METHODS ...

In birds with altricial young an important stage in the life history is the age at fledging. In this paper we use an approach proven successful in the prediction of the optimal age at maturity in fish and reptiles to predict the optimal age of fledging in passerines. Integrating the effects of growth on future fecundity and survival leads to the prediction that the optimal age at fledging is gi...
