In contrast to the United States and European countries, China has witnessed a widening gender pay gap in the past two decades. Nevertheless, the size of the gender pay gap could still be underestimated as a result of not accounting for the low-wage women who have dropped out of the labor force....

Using meteorological data and mathematical statistics analysis, we take Jungar Banner in the northern farming-pastoral region of China for example, to analyze the fluctuations in the precipitation and average temperature in Jungar Banner during the period 1961-2009. We calculate the NPP value of...

Yunnan Province is the bridgehead for the opening of the southwest region in China, and the economic frontier of China-ASEAN economic cooperation, where the export of agricultural products plays an important role in promoting the openness of the southwest region and strengthening China-ASEAN...

Probability generating function (p.g.f.) is a powerful tool to study discrete compound Poisson (DCP) distribution. By applying inverse Fourier transform of p.g.f., it is convenient to numerically calculate probability density and do parameter estimation. As an application to finance and...

In order to curb anthropogenic carbon emissions and achieve the carbon intensity reduction target in China, it is crucial to shed light on influencing factors of carbon emissions at the city level. This paper selects Tianjin, one of the largest economic centers in northern China, as a study...

Based on the geological data of the Qinghai-Tibet plateau permafrost, such as the permafrost ground temperature, the thermal gradient within and below the frozen layer, we numerically investigate the gas production potential from hydrates at the DK-3 drilling site of the Qilian Mountain...

Based on the available measurement data and literature on the hydrate deposits of the South China Sea, a numerical simulation with a new dual horizontal well system has been carried out. Warm brine stimulation combined with depressurization is employed as the production method. Two horizontal...

Our proposed local vector autoregressive (LVAR) model has time-varying parameters that allow it to be safely used in both stationary and non-stationary situations. The estimation is conducted over an interval of local homogeneity where the parameters are approximately constant. The local...

The Grain for Green program (GGP) is one of the most ambitious forestry projects in China. The GGP uses a public payment scheme to propel the participation of rural households in order to make the program acceptable and sustainable. The modification of the GGP for its long-term effectiveness has...

In recent years, some authors have incorporated the penalized likelihood estimation into designing multivariate control charts under the premise that in practice typically only a small set of variables actually contributes to changes in the process. The advantage of the penalized likelihood...
