Within-culture variation in field dependence/independence: A region-level investigation across China

Field dependence/independence (FDI), refers to one's preferred style in perceiving one's surroundings, either analytically and individually, or globally and collectively, and has been a popular topic in recent cross- and within-culture research. Previous researchers have suggested that members of individualist and collectivist cultures differ in the degree to which they perceive objects either analytically and context-independently or holistically and context-dependently. Cross-culture variation in FDI has been thoroughly studied, whereas within-culture investigations have seldom been undertaken. We explored the within-culture variation of FDI with 593 Chinese colleague students, via administering the Embedded Figures Test. As we predicted, results showed that participants from the more individualist north China area exhibited stronger degrees of field independence than did their more collectivist southern counterparts. We have supported and extended the notion that culture affects individual experiences on a basic perceptual level with new within-culture data.

Research on Upper Limit Increased of Mining in Coal Mining Face

In order to guarantee the safety of the coal mine, needing to leave in reasonable waterproof safety coal pillar. Aiming at the working face 3311 of Xuchang coal mine, this article based on the analysis to the basis of factors for improving the mining limit, using UDEC numerical simulation, the regulations of coal mining under buildings, railways and water bodies and historical experience to analyze crack-production ratio of the working face, study the height of water flowing fractured zone development, designing test mining program. Through the upper mining limit to liberate 160000t coal resources and to gain the obvious economic benefits, which provide important significance for other similar coal mines in coal field of North China area.

Study of Wind Power Forecasting Assessment Standard Based on Unit Commitment and Spinning Reserve Optimization Model

After large-scale wind power integrate into the system, there is a great impact for the system dispatching operation and the unit maintenance and repair of the wind power , so it's extremely necessary to forecast wind power output and assess its level of forecasting. This paper mainly focusing on the containing wind power system, studies the wind power output fluctuation in the demand for system reserve, and analyse the rationality of the wind power forecasting assessment standard in North China area wind power integration operation management implementing regulations by combining with the status of wind power in North China area, that is, whether the assessment mechanism can promote wind farms raising the forecasting level.
