According to conventional wisdom, family ownership, which signals a lack of social capital and trust in an economy, may impede innovation. This argument, however, fails to recognize that modern family firms can benefit from capitalist institutions that promote innovation. Using a comprehensive...

We investigate the impact of the absence of short selling on the pricing of managerial skills in the mutual fund industry. In the presence of divergent opinions regarding managerial skills, fund managers can strategically use fees to attract only the most optimistic capital. The recognition of...

With the advance of urbanization process and rapid growth of urban population, the construction land scale in Dianchi Lake basin increases at a sharp speed. Due to lack of reasonable scale control and space optimization, many areas have the problem of blind growth in construction land. On the...

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,...

Illumination factors can affect growth of microalgae and HCO3− fixation. In order to optimize microalgae growth in culture system and HCO3− fixation from wastewater, the effects of light source, light interval on the growth of microalgae, Chlorella sp. and Scenedesmus obliquus sp., were...

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...

To examine the impact of trade barrier reductions on the Chinese economy following its WTO accession, a single-country, static CGE (Computable General Equilibrium) model is constructed, which incorporates certain elements of imperfect competition in China's current economic situation. China's...

We develop a unified L₁-based analysis-of-variance-type method for testing linear hypotheses. Like the classical L₂-based analysis of variance, the method is coordinate-free in the sense that it is invariant under any linear transformation of the covariates or regression parameters. Moreover, it...

Consider the interval mapping method for quantitative trait loci (QTL) detection of an experimental organism in a backcross population. In a recent paper, Chen and Chen [2005. On some statistical aspects of the interval mapping for QTL detection. Statist. Sinica 15, 909-925] show that the...

Case-control association studies using unrelated cases and controls may suffer from potential confounding due to population stratification. Bias and variance distortion caused by population stratification in the commonly used allele-based tests can considerably inflate the Type I error rate. It...
