In longitudinal data analysis with dropouts, despite its local efficiency in theory, the augmented inverse probability weighted (AIPW) estimator hardly achieves the semiparametric efficiency bound in practice, even if the variance–covariance of the longitudinal outcomes is correctly modeled....

In recent years, an increasing number of Chinese wind power firms have been going international in search of global market for development channels. By employing qualitative research and case study methods, this paper examines the export scale and markets of China’s wind turbines, the market...

The paper addresses a critically important area in Canadian immigration and health from both a social and a spatial perspective. It employs multilevel and contextual approaches to examine the social determinants of immigrant health as well as the place effects on self-reported health at a...

This paper analyzes the long-term relationships between hydropower generation and climate factors (precipitation), hydropower generation capacity (installed capacity of hydropower station) to quantify the vulnerability of renewable energy production in China for the case of hydropower...

We assume a multi-agent model based on Parrondo’s games. The model consists of game A between individuals and game B. In game A, two behavioral patterns are defined: competition and inaction. A controlled alternation strategy of behavioral pattern that gives a single player the highest return...

In our previous study [Zhu et al., Quantum game interpretation for a special case of Parrondo’s paradox, Physica A 390 (2011) 579], the capital-dependent Parrondo’s game where one game depends on the capital modulus M=4 was shown not to have a definite stationary probability distribution and...

For the multi-agent spatial Parrondo’s games, the available theoretical analysis methods based on the discrete-time Markov chain were assumed that the losing and winning states of an ensemble of N players were represented to be the system states. The number of system states was 2N types....

This paper analyzes the long-term relationships between hydropower generation and climate factors (precipitation), hydropower generation capacity (installed capacity of hydropower station) to quantify the vulnerability of renewable energy production in China for the case of hydropower...

The current cost-plus natural gas pricing mechanism makes the gas price too low, resulting in a lot of consumer-side subsidies, which makes natural gas over-consumed. This paper applies the price-gap approach and input-output analysis technology to quantitatively analyze both of the direct and...
