We suggest and compare different methods for estimating spatial autoregressive panel models with randomly missing data in the dependent variable. We start with a random effects model and then generalize the model by introducing the spatial Mundlak approach. A nonlinear least squares method is...

We put forward a quick clustering method for large numbers of data, with high dimensions, which is based on sensitive subspace consisting of the data set's sensitive dimensions. We first estimate the probability density of each dimension by the parzen window algorithm, enhance its optional...

Although access to quality education in rural China has expanded dramatically over the past 3 decades, significant disparities persist between ethnic minorities and the Han majority. This article compares the academic achievement and determinants of achievement of minority and Han students in...

We have examined the volatility and macroeconomic drivers of venture capital (VC) investments in the past 17 years from 1995 to 2011. We find that VC investments in the United States (US) by the total amount, by the number of deals, and by the average amount per deal are significantly affected...

This paper presented a case study on performance analysis of ground water-source heat pump system (GWHP) for a hotel building retrofit. Splitting air-conditioner was used for cooling and coal fired boiler was used for heating in original system. The GWHP system could save electricity energy and...

This paper explores the role of financial frictions in accounting for agricultural productivity differences. A two-sector general equilibrium model with a subsistence consumption requirement and financial frictions is constructed to explain and quantify the importance of financial frictions in...

Positive-displacement expanders, which are widely used in small-scale ORCs (Organic Rankine Cycles), need reliable LOS (Lubricant Oil Supply) to get well lubrication and sealing. In the present paper, the characteristics of two traditional LOS schemes are examined. Moreover, a modified one is...
