In this paper, we propose a class of models for generating spatial versions of three classic networks: Erdös-Rényi (ER), Watts-Strogatz (WS), and BarabásiAlbert (BA). We assume that nodes have geographical coordinates, are uniformly distributed over an m 9 m Cartesian space, and long-distance connections are penalized. Our computational results show higher clustering coefficient, assortativity,...

This study aims to explore the effect of the neighborhood scale when estimating public services inequality based on the aggregation of social, environmental, and health-related indicators. Inequality analyses were carried out at three neighborhood scales: the original census blocks and two aggregated neighborhood units generated by the spatial "k"luster analysis by the tree edge removal (SKATER...

As an indicator of social development and human capital, health has aroused ever-increasing concerns. Using CHNS2000 data, we attempt to address the following two issues: how could income inequality influence health; does the rising income inequality result in health inequality, especially will the health of the lower-income group get worse. We find that there is an “inverted-U” association bet...

This trend has been faced without effective policies and programs. Consequently, a great opportunity has been transformed in a great threat and the word immigration is generally associated with the term social security...
