Security surveillance is one of the most important issues in smart cities, especially in an era of terrorism. Deploying a number of (video) cameras is a common surveillance approach. Given the never-ending power offered by vehicles to metropolises, exploiting vehicle traffic to design camera placement strategies could potentially facilitate security surveillance. This article constitutes the fi...

In cities’ policy-making, it is a hot issue to grasp the determinants of carbon dioxide emission in Chinese cities. And the common method is to use the STIRPAT model, where its coefficients represent the influence intensity of each determinants of carbon emission. However, less work discusses estimation accuracy, especially in the framework of non-normal distribution and heterogeneity among cit...

This article uses the evaluation of the Robert Wood Johnson Foundation’s (RWJF) Urban Health Initiative (UHI), a 10-year effort to improve health and safety outcomes in distressed cities, to demonstrate the strength of an evaluation design that integrates theory of change and quasiexperimental approaches, including the use of comparison cities. This paper focuses on the later stages of implemen...

This paper examines the spatial structures of commercial real estate buildings (Offices, Retails) in four Chinese cities: Beijing, Shanghai, Shenzhen, and Guangzhou. In contrast to previous studies, this paper focused on the changes of the spatial pattern by involving the time variables to categorize the buildings into 3 time periods (Before 1995, 1996-2005, and 2006-2015). The research questio...

The efforts made to plan cities in emerging and developing countries are confronted to multiple issues, especially in small and middle sized cities which can be considered as poor through several criteria: socio-economic level of majority of population; low levels of public investments, weak quality of local administration, and large dependence of external donors. Following several authors, one...

Supply chains provide the critical infrastructure for the production and distribution of goods and services in our Network Economy and serve as the conduits for the manufacturing, transportation, and consumption of products ranging from food, clothing, automobiles, and high technology products, to even healthcare products. Cities as major population centers serve not only as the principal deman...

The Effects of Living Wage Laws: Evidence from Failed and Derailed Living Wage Campaigns Living wage campaigns have succeeded in about 100 jurisdictions in the United States but have also been unsuccessful in numerous cities. These unsuccessful campaigns provide a better control group or counterfactual for estimating the effects of living wage laws than the broader set of all cities without a l...
