We present a new, global data base on tourist destinations. The data base differs from other data bases in that it includes both domestic and international tourists; and it contains data, for the most important destinations, data at national level as well as at lower administrative levels....

Many industrial processes need steam at temperatures from 100 to 200 °C, normally produced by directly heating water via coal, natural gas or oil combustion. Nevertheless, large amounts of unused heat below 100 °C are wasted in other industrial processes. In principle, a high-temperature...

China is a country with severe water shortages. Water becomes scarcer due to population growth, industrialization and urbanization. Recent studies show that by the next 50 years water resources per capita will go down to around 1700 m3, which is the threshold of severe water scarcity. Especially...

Many regions of the world are facing formidable freshwater scarcity. Although there is substantial scope for economizing on the consumption of water without affecting its service level, the main response to water scarcity has been to increase the supply. To a large extent, this is done by...

Demand management plays an increasingly important role in dealing with water scarcity in China. It is important to understand the level and pattern of water use in various sectors across the regions for any measures being put into effect. The aim of this study is to enhance the understanding of...

Although China has made dramatic economic progress in recent years, air pollution continues to be the most visible environmental problem and imposes significant health and economic costs on society. Using data on pollutant concentration and population for 2003, this paper estimates the economic...

The paper discusses the development of the third mission of Chinese universities. The main approaches and challenges of two universities, Tsinghua University and Beihang University, are examined to elucidate the third mission of Chinese research universities in a knowledge-based economy. The...

A conditional test based on a Hotelling'sT2-type statistic is derived for significance of a multivariate mean having non-negative components. This test is shown to be uniformly more powerful than the unconditional test given by Silvapulle. The consistency and invariance of the new test are also...

This note shows a major problem in the proof of Anscombe's conjecture given in Aragon et al. (1992). It also proves that the unbiased estimator of the parameter k does not exist.
