Online rating can directly reflect users’ collective behavioral patterns which is of great concern in online social systems. In this paper, we investigate the correlations between the users’ rating behaviors and the real-time updated average ratings of objects given from other users’...

The objectives of this paper are twofold. First, we aim to clarify the mechanism by which use of farm machinery in Chinese agriculture has grown rapidly over the past decades, using a separate Cobb–Douglas (SCD) production function. Second, we determine under what condition will China's grain...

Online users’ collective interests play an important role for analyzing the online social networks and personalized recommendations. In this paper, we introduce the information entropy to measure the diversity of the user interests. We empirically analyze the information entropy of the objects...

The risk management of New Zealand's foreign exchange reserves is discussed.

The chord and twist angle radial profiles of a fixed-pitch fixed-speed (FPFS) horizontal-axis wind turbine blade are based on a particular design wind speed and design tip speed ratio. Because the tip speed ratio varies with wind speed, the originally optimized chord and twist angle radial...

A wind turbine blade generally has complex structures including several layers of composite materials with shear webs. It is essential but also inherently difficult to accurately and rapidly calculate the cross-sectional properties of a complex composite blade for the structural dynamics and...

Foreign direct investment (FDI) can benefit domestic firms in the host country. Using firm-level data for China, we find statistically positive vertical spillover effects of multinational enterprises on the performance of domestic firms through backward and forward supplier–customer...

Most existing social learning models assume that there is only one underlying true state. In this work, we consider a social learning model with multiple true states, in which agents in different groups receive different signal sequences generated by their corresponding underlying true states....

Having a clear understanding of consumers' awareness of genetically modified food and their willingness to buy, plays a very important role in formulating the regulatory policy of genetically modified food and regulating the market of genetically modified food. This paper takes the supermarket...
