In this paper, a land utilization efficiency evaluation model, which takes environmental loss into consideration, has been structured via taking advantage of the slack-based measure (SBM) model. Meanwhile, based on the panel data from 280 prefecture-level cities in China from 2003 to 2013, the paper thoroughly probed into, and discussed, the effect imposed by industry clustering and specializat...

Although a growing body of research has examined and found a positive relationship between neighborhood crime and home foreclosures, some research suggests this relationship may not hold in all cities. This study uses city-level data to assess the relationship between foreclosures and crime by estimating longitudinal models with lags for monthly foreclosure and crime data in 128 cities from 199...

Big data and predictive analytics have the potential to make cities more efficient. Yet cities often lack the resources to use new data and methods effectively, and private researchers often lack the incentives to help solve the problems that cities face. New platforms—such as Kaggle, TopCoder, and DrivenData—now enable governments and other organizations to outsource large-scale prediction pro...

Minneapolis/St. Paul, because of its history of health maintenance organization development and active employer participation in the health care arena, is often cited as a community in which managed competition has been tested to some degree. This paper reviews the historical development of the Twin Cities health care market and summarizes findings from past studies of this market. It also desc...

Residential segregation by jurisdiction generates disparities in public services and education. The distinctive American pattern—in which blacks live in cities and whites in suburbs—was enhanced by a large black migration from the rural South. I show that whites responded to this black influx by leaving cities and rule out an indirect effect on housing prices as a sole cause. I instrument for c...

In recent years, news of ‘‘cancer villages” in the Huaihe River Basin filled front and back pages of newspapers and generated elevated concern among readers. This study aims to understand the relationship between the ‘‘cancer villages” and the ‘‘large cities” around them. A gravity model is constructed to analyze the correlation between ‘‘big cities” and ‘‘cancer villages” in terms of indices i...

To what extent do politicians reward voters who are members of their own ethnic or racial group? Using data from large cities in the United States, we study how black employment outcomes are affected by changes in the race of the cities’ mayors between 1973 and 2004. We find that black employment and labor force participation rise, and the black unemployment rate falls, during the tenure of bla...

A new air mass-based synoptic procedure is used to evaluate climate/mortality relationships as they presently exist and to estimate how a predicted global warming might alter these values. Forty-four large U.S. cities with metropolitan areas exceeding 1 million in population are analyzed. Sharp increases in mortality are noted in summer for most cities in the East and Midwest when two particula...

In the event of a catastrophic or large scale event, demand for Emergency Medical Service (EMS) vehicles will almost certainly overwhelm the available supply. In such cases, it is necessary for cities to request aid (in the form of added capacity) from neighboring municipalities in order to bring the affected region back to its day-to-day levels of operation. In particular, we consider a region...

B rownfield sites are a common eyesore on the edges of many cities; the abandoned, decaying hulks of industrial or commercial structures sit rusting and forgotten while they leach harmful chemicals such as asbestos, solvents or heavy metals into the soil. Some brownfields lie virtually untouched for years because it is often cheaper to expand cities into virgin territory than to demolish large ...
