The existing literature treats the short side (i.e., short selling) and long side of hedge fund trading (i.e., changes in holdings) independently. The two sides, however, complement each other in revealing important economic motivations of trading: opposite changes in short interest and hedge...

The rise of social media has encouraged guru dreams because of the low entry barrier and highly skewed distribution of public attention that characterize social media. The pursuit of guru status, however, may be achieved through information provision or cheap talk, and competition inherent to...

In the paradigm of the search theory, we established the search model applicable to the characteristics of China's resale housing market, by modeling the search behavior for buyer and seller, respectively. Setting the parameters based on the Beijing housing market survey in August 2012, we...

Relying on the management system for agricultural sci-tech achievement transformation funding project in Zhejiang Province, on the basis of current situations and demand of agricultural sci-tech achievement transformation funding project management system, we present a B/S-structured and J2EE...

Based on the diagnosis of the industrial structure in the Xi'an metropolitan area, we point out the problems in the development of urban and rural industries in the Xi'an metropolitan area: there is imbalance in the industrial structure; the planning and layout is chaotic; the service system is...

We investigate the topological properties of N(N⩾1) disclination lines in cholesteric liquid crystals. The topological structure of N disclination lines is obtained with the Hopf index and Brouwer degree. Furthermore, the knotted χ disclination loops is proposed with the Hopf invariant. And...

Using wastewater to grow algae is probably the most promising route to reduce production costs associated with nutrients and water. In this study, a newly isolated facultative heterotrophic freshwater microalgae strain, Auxenochlorella protothecoides UMN280, was examined for algal growth,...

Two-step logit models are extensions of the ordinary logistic regression model, which are designed for complex ordinal outcomes commonly seen in practice. In this paper, we establish some asymptotic properties of the maximum likelihood estimator (MLE) of the regression parameter vector under...

This paper is concerned with the existence and exponential stability of positive almost periodic solutions of shunting inhibitory cellular neural networks (SICNNs) with time-varying delays arising from the description of the states of neurons in delayed neural networks in a time-varying...
