With the rapid development of the Internet and the promotion of mobile Internet, microblogs have become a major source and route of transmission for public opinion, including burst topics that are caused by emergencies. To facilitate real time mining of a large range of burst topics, in this...

Pyrolysis-gas chromatographic mass spectrometry (Py-GC/MS) was used to determine the yield and chemical composition of the pyrolysis products of <i>Schizochytrium limacinum</i>. The pyrolysis was carried out by varying the temperature from 300 °C to 800 °C. It was found that the main decomposition...

Purpose - The purpose of this paper is to analyze the different types of domestic waste disposal in rural China and the major factors that affect rural household waste disposal behavior. Design/methodology/approach – Stratified and randomly sampled household data are used to describe the...

This paper investigates the relationship in China between trade, growth and emissions using provincial-level data for water (chemical oxygen demand: COD) and air (sulphur dioxide: SO2). It analyses the period 1990–2007 in three steps. First, the income ‘turning point’ of the Environmental...

Most climate scientists around the world are concerned about global warming. These concerns have resulted in calls for reductions in CO2 emissions over time. If these calls are to be heeded, an appropriate emissions accounting method must first be agreed upon by CO2 emitting countries, none of...

Cr/SmCo5/Cr films were fabricated by a DC facing targets magnetron sputtering. The influences of sputtered Ar pressure and substrate temperature on their microstructure and magnetic properties were investigated. Magnetic measurements indicate that the optimal substrate temperature was 450°C,...

This paper considers a non-autonomous competitive two-species model with stage structure in one species. The conditions of permanence obtained. Furthermore, the existence and asymptotic stability of the periodic solution are proved under some assumptions if this model turns out to be a periodic...

This paper measures the economies of scale of Canada's six largest banks and their cost-efficiency over time. Using a unique panel data set from 1983 to 2003, we estimate pooled cost functions and derive measures of relative efficiency and economies of scale. The disaggregation of the data...

Data suggest that the Canadian financial structure, and particularly indirect finance (e.g., banking), have become more market-oriented. we associate this financiel trend in part with the regulatory changes that have occured in Canada since the 1980s. Financial intermediaries are increasingly...
