China’s new urbanization development strategy needs to be supported by rational urban systems. Here, a comprehensive diagnostic index system that uses GIS technology and a Chinese urban scale structure rationality diagnostic model, functional structure rationality diagnostic model, spatial...

An early-warning indicator screening method is proposed in order to construct an early-warning system for vegetable prices. Through index contribution analysis and the application of a support vector regression algorithm, we compare the results of early warning before and after index...

During the last decades, society’s concern for the environment has increased. Specific tools like the Life Cycle Assessment (LCA), and software and databases to apply this method have been developed to calculate the environmental burden of products or processes. Calculating the environmental...

Fuel economy standards change the composition of the vehicle fleet, potentially influencing accident safety. I introduce a model of the fleet that captures risks across interactions between vehicle types while simultaneously recovering estimates of unobserved driving safety behavior. The model...

Landscape design, construction and management should no longer be the result of superficial approaches based exclusively on designers’ and planners’ ideas. This research starts with the assumption that the aesthetic component constitutes an essential attribute for better understanding and...

Sustainable energy production and consumption is one of the issues for the sustainable development strategy in China. As China’s economic development paradigm shifts, household energy consumption (HEC) has become a focus of achieving national goals of energy efficiency and greenhouse gas...

As the number of speech and video documents increases on the Internet and portable devices proliferate, speech summarization becomes increasingly essential. Relevant research in this domain has typically focused on broadcasts and news; however, the automatic summarization methods used in the...

The acceleration of urbanization and industrialization has been gradually aggravating water security issues, such as water shortages, water pollution, and flooding or drought disasters and so on. Water security issues have become a great challenge to urban sustainable development. In this...

Simulation models of emissions trading performance are generally based on the assumption that carbon prices are fully (or almost fully) passed through to energy prices (with pass-through rates equal or very close to one). Unfortunately, empirical analyses of wholesale electricity spot markets do...

We review nonparametric estimation of efficiency and productivity, by which we mainly mean activity analysis, or data envelopment analysis (DEA). The review covers topics that we hope will be of special interest to those doing research in the realm of agriculture. We also include a brief...
