Recommender systems represent an important tool for news distribution on the Internet. In this work we modify a recently proposed social recommendation model in order to deal with no explicit ratings of users on news. The model consists of a network of users which continually adapts in order to...

Through the collection of related literature, we point out the six major factors influencing China's forestry enterprises' financing: insufficient national support; regulations and institutional environmental factors; narrow channels of financing; inappropriate existing mortgage-backed approach;...

We offer an institution-based view to the classic inquiry on the relationship between family business and firm performance, which has been dominated by traditional theories such as agency theory and the resource-based view. Specifically, we argue that institutions define family business...

Extant research offers two alternative mechanisms for relating the asset specificity of a cooperative relationship to partnership performance. Transaction cost economics argues that the specific assets invested in a partnership increase the hazards of opportunism. As firms select appropriate...

Disaster insurance programs have been recognized as an effective strategy to reduce agricultural production risk. Although a considerable body of literature has focused on natural disaster insurance programs for agricultural producers, not much is known about forest disaster insurance. This...

One important property of any drug product is its stability over time. Drug stability studies are routinely carried out in the pharmaceutical industry in order to measure the degradation of an active pharmaceutical ingredient of a drug product. One important study objective is to estimate the...

By means of the electrostatic device, this paper researched and analyzed the effect of electrostatic treatment on the scaling of water. The results show when the charge time is 10 s, the optimal zone of tension is 400–500 V and the average efficiency is between 14% and 35%; but when the...

The internal and external exergy efficiencies are adopted to analyze the impact of working fluids on the performance of the organic Rankine cycle, and a simplified internal exergy efficiency model is proposed to indicate this impact. The calculation results show that the thermophysical...
