This paper precisely characterizes asymptotic behaviors of the volatilities in nonstationary GARCH(1, 1) models. After suitable renormalization, it is shown that the volatility converges in distribution to a non-degenerate limit. This provides more insight into the dynamics of volatilities in...

Davidson (2004) recently proposed the hyperbolic GARCH model to capture the phenomenon of long-range dependence in volatility, with the extent of such dependence measured by the geometric or hyperbolic decay of the coefficients in an ARCH(∞) model. In this article, we reinterpret the...

In this paper, we employ the Hilbert–Huang Transform to investigate the multifractal character of Chinese stock market based on CSI 300 index. The measured Hilbert moment Lq(ω) shows a power-law behavior on the range 0.01ω0.1min−1, equivalent to a time scale range 10τ100min. The measured...

In this paper, the thermophysical properties of the H2O+1,3-dimethylimidazolium dimethylphosphate ([DMIM]DMP) system were studied. The boiling point method was adopted to measure the vapor pressures of the system at mass fraction of ionic liquids (ILs) in the range from 0.10 to 0.90 as well as...

A 50kg/h autothermal two-stage gasifier, consisting of a fluidized bed (FB) pyrolyzer and a downdraft fixed-bed gasifier, has been designed and built according to our previous laboratory researches. In the experiments, lignite gasification was performed in this innovative two-stage gasifier to...

We consider the effect of national culture and corporate culture differences on the management of international strategic alliances (ISAs). Findings are based on the perceptions of a relatively large sample of Chinese partner firms in ISAs with foreign partners. We find that differences in...

We examine the strategic motivation for international strategic alliance (ISA) formation and partner selection criteria in a sample of 203 Chinese ISAs using questionnaire data obtained from Chinese partners. The highest ranked strategic motives of the Chinese firms are maintaining market...
