Employing a recently developed method-mixed data sampling (MIDAS) approach - to assess the risk-return trade-off for Chinese stock markets, our results are striking. First, we fail to find any evidence of the risk-return trade-off in the first subsample (Jan 1993¨CJan 2001), while we do find...

In this paper, a novel hybrid ensemble learning paradigm integrating ensemble empirical mode decomposition (EEMD) and least squares support vector regression (LSSVR) is proposed for nuclear energy consumption forecasting, based on the principle of “decomposition and ensemble”. This hybrid...

Accurate prediction of the remaining useful life (<i>RUL</i>) of lithium-ion batteries is important for battery management systems. Traditional empirical data-driven approaches for <i>RUL</i> prediction usually require multidimensional physical characteristics including the current, voltage, usage duration,...

Due to the distinct seasonal characteristics of hydropower, this study tries to propose a seasonal decomposition (SD) based least squares support vector regression (LSSVR) ensemble learning model for Chinese hydropower consumption forecasting. In the formulation of ensemble learning model, the...

In this paper, we consider a stochastic SIS epidemic model with vaccination. We prove that the densities of the distributions of the solution can converge in L1 to an invariant density under appropriate conditions. Also we find the support of the invariant density.

Magnetic properties of a biaxial spin-1 system in an applied transverse field are investigated by using the effective-field theory with correlations on the basis of the differential technique. We have studied the effects of the transverse field on the phase diagrams, internal energy, and...

In international joint ventures (IJVs), partner firms exert three types of management control: output, process, and social. Since management control critically influences IJV success, it is essential to understand what factors drive the development of the control system. Prior studies have...

As emerging markets develop, foreign firms are being viewed less and less as providers of capital and/or technology, and more as integral parts of society in general, with much greater responsibilities that stem largely from their multinational roles. Recognizing these pressures and the...

This paper examines the performance of Silicon Valley ventures with Asian-American founding teams. We review some challenges faced by these ventures, compare their performance with that of other ventures, and analyze the impact of strategic partnerships on their performance. Our results indicate...

We find that firms that provide limited liability and indemnification for their directors enjoy higher credit ratings and lower yield spreads. We argue that such provisions insulate corporate directors from the discipline from potential litigation, and allow them to pursue their own interests by...
