Influence of social media on operational efficiency of national scenic spots in china based on three-stage DEA model

An increasing number of national scenic spots around the world use social media, such as micro-blogs and Twitter, to promote their popularity and improve their operational performance. National scenic spots may adopt different social media behaviors that lead to unbalanced operational performance. This study takes the perspective of social media adoption in national scenic spots by looking into the influence of social media adoption behaviors on operational performance based on the three-stage data envelopment analysis model. We found that most of the national scenic spots in China have low pure technical efficiency and that operational performance, including social media popularity and operational performance, is significantly determined by various social media adoption behaviors.     

从成本考量的视角看人类对民主政体的理性选择

民主政体作为人类政治文明的发展形态已有数千年的存在历史。人类之所以在当今普遍选择民主政体作为最基本的现实政治运作模式,也是基于成本考量的理性选择。民主政体相对于其他政体而言,具有比较优势。民主政体相对于其他政体而言,不仅能够有效降低调和政治冲突和维持政治及社会稳定的政治成本,而且能够有效降低公共决策的外部成本,更能够有效降低政治统治的风险成本和政治发展的机会成本。理性考察和分析民主政体的成本问题,不仅有利于加深对民主的理论认识,而且更有利于增强如何将社会主义民主做真做实的现实思考。

成就目标的概念和测量存在的问题

在过去的二十多年中,成就目标理论已经成为成就动机研究中最杰出的理论之一。但在现有的文献中,成就目标概念至少具有三种不同的含义：期望的结果、期望的结果与原因的组合、总体定向;成就目标的测量工具也存在一系列问题。未来的研究需要进一步完善成就目标的测量工具,来探讨成就目标与其影响因素和结果变量的关系;未来的研究可以考虑在成就目标问卷中增加自我参照目标的项目,来检验成就目标的3×2结构模型。     

Experimental performance of moderate and high temperature heat pump charged with refrigerant mixture BY-3

Theoretical and experimental analysis of a new refrigerant mixture BY-3 was conducted based on a single-stage vapor compression refrigeration system. The water-water heat pump system used BY-3 to produce hot water when the low temperature was 20 ℃. The following results were obtained: the highest temperature at the condenser outlet reached about 85 ℃; when the difference between the water temperatures at the condenser outlet and the evaporator inlet was less than 40 ℃, the coefficient of performance (COP) was larger than 4; when the difference reached 55 ℃, the COP still kept 3; the discharge temperature of BY-3 was lower than 100 ℃, and the refrigerant vapor pressure kept lower than 1.8 MPa. When the water temperature at the condenser outlet reached over 85 ℃, nearly a 5 ℃ superheating temperature was maintained.

The interplay between self-determined motivation,self-regulated cognitive strategies,and prior achievement in predicting academic performance

The present study examined the interplay between self-determined motivation and the use of cognitive strategies in predicting university students’ academic performance while taking into account the effect of prior achievement. A theory based model was tested using structural equation modeling on a sample of 764 Italian university students. Results showed that prior achievement influenced students’ academic performance and their motivation and use of cognitive strategies. Critical thinking was the only cognitive strategy which proved to have a significant impact on students’ academic performance. Autonomous motivation had an indirect positive impact on academic performance through its influence on the critical thinking strategy. Controlled motivation had a direct negative impact on academic performance. On the whole, our findings suggest that autonomously motivated students tend to achieve better academic performance by using critical thinking, while students who are driven by controlled motivation have lower academic performance.
