The aim of this study is to find whether the h-index and Schubert-Glänzel model which was originally used in bibliometrics can work in the broader social and information systems, such as e-commerce. This study introduces the popularity index (hP) to profile on-line sellers and products and tests the accuracy of the Schubert-Glänzel model of the hP index using the Levenberg-Marquardt algorithm. The hP index was tested on Taobao, a leading Chinese e-commerce marketplace. About 300 products on Taobao were randomly selected from 10 categories of the most popular on-line products as samples for this study. It was found that hP is consistent with the Schubert-Glänzel model the h-index. This shows that the existing theoretical bibliometric model which was originally used in the scientific literature, could be helpful in the broader social or information systems.Keywords

This paper utilizes the emission data of four kinds of waste gas which are closely linked with haze pollution from 2012 to 2013 in China (total emission of industrial sulphur dioxide, industrial smoke dust, industrial dust, and industrial waste gas) and analyses the fluctuation of industrial waste gas emission within the period, as well as the differences in spatial distribution in the 31 provinces, cities, and autonomous regions to understand the correlations between waste gas emission and the degree of haze pollution and between the industrial development levels of different provinces and haze pollution during the industrial development in China. The studies indicate that haze pollution is mainly caused by industrial waste gas discharge resulting from unreasonable industrial energy consumption structure. The yearly emission of industrial waste gas increases nearly five times greater in 2013 than in 2000. However, the emission of industrial smoke, dust, and industrial dust yearly decline, thereby reducing haze pollution. The emission of industrial sulphur dioxide slightly fluctuates, negatively affecting haze pollution reduction. The unequal development of Chinese industrial regions causes unequal haze pollution in regions. The provinces with a substantial share of heavy industry in economics have more serious haze pollution. This research improved our understanding of the correlation between waste gas discharged by industries and haze pollution. The conclusions obtained in this study can be used to explore energy conservation and emission reduction in industrial manufacturing to reduce haze pollution and guide the outline of specific legal regulations in controlling haze pollution.Keywords

An effort is made to study the mechanical features and AE characteristic parameters of filling bodies under repeated loading and unloading, which are common stress paths for the filling bodies of mine, to providing theoretical basis for the monitoring and the bracing of backfilled mine. Material testing machine RMT-150C is used to conduct uniaxial compression experiments on cemented filling body under above mentioned stress paths and 1MHZ broad-band emission sensor is employed to collect AE parameters prior to the arrival on peak compression strength. The results indicate that comparing to monotonic loading, cyclic loading could elevate the peak stress of filling bodies by about 30%. The stress-strain-accumulative AE number curves of specimens under cyclic loading tells the surge of accumulative AE number on specimens’ reaching peak stress, which combining with test process proves the thorough failure of filling body. It is then demonstrated that the surge of accumulative AE number could serve as a reference criterion for judging the failure of filling bodies.Keywords
