How to get out of the prisoners�� dilemma: Educational resource allocation and private tutoring

This paper analyzes the behavior of families in China regarding private tutoring, applying game theory to its discussion of their actions. It finds that families will definitely give their children private tutoring after school in order to obtain better educational opportunities in situations where the distribution of educational resources is uneven. According to game theory, overuse of private tutoring after school will waste societal resources and negatively affect all the players in the game. It is argued that a key strategy to reduce private tutoring after school is to close the gaps in state provision of education.     

Lumped parameter model for resonant frequency estimation of a thermoacoustic engine with gas-liquid coupling oscillation

Gas-liquid coupling oscillation is a novel approach to reducing the resonant frequency and to elevating the pressure amplitude of a thermoacoustic engine. If a thermoacoustic engine is used to drive low-frequency pulse tube refrigerators, the frequency matching between the thermoacoustic engine and the refrigerator plays an important role. Based on an acoustic-electric analogy, a lumped parameter model is proposed to estimate the resonant frequency of a standing-wave thermoacoustic engine with gas-liquid coupling oscillation. Furthermore, a simplified lumped parameter model is also developed to reduce the computation complexity. The resonant frequency dependence on the mean pressure, the gas space volume, and the water column length is computed and analyzed. The impact of different working gases on the resonant frequency is also discussed. The effectiveness of the models is validated by comparing the computed results with the experimental data of the gas-liquid coupling oscillation system. An increase in the mean working pressure can lead to a rise in the resonant frequency, and a lower resonant frequency can be achieved by elongating the liquid column. In comparison with nitrogen and argon, carbon dioxide can realize a lower frequency due to a smaller specific heat ratio.

Screening study of transition metal oxide catalysts supported on ceria-modified titania for catalytic oxidation of toluene

Six transition metal oxides were added in ceria-modified titania using a sol-gel method for catalytic oxidation of toluene. An MnOx based catalyst was found to be the most active one, with which toluene could be decomposed completely at 200 °C. The greatest Mn/Ti and molar ratio of the mobile oxygen to the total oxygen concentration, together with a large surface area and a low reduction peak-starting temperature, would result in its best activity in toluene oxidation.

Behavioral Intention to Adopt Digital Library by the Undergraduates

The purpose of this research is to investigate the factors that affect undergraduates' behavioral intention to use digital library among the private universities in Malaysia. The target respondents are undergraduates from Malaysian private universities. Questionnaires were distributed among 500 undergraduates through either online or face-to-face method. Reliability test, normality test, Pearson Correlation Coefficient analysis, and Multiple Linear Regression (MLR) were carried out for data analysis. Performance expectancy, social influence, facilitating conditions, hedonic motivation, habit, and information quality had a positive and significant association with behavioral intention to adopt a digital library except for effort expectancy. This research successfully reinforced that the inspiration to ameliorate Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) by synthesis of Information Systems Success Model (ISSM). This proposed framework with a combination of ISSM and UTAUT 2 has enhanced the fitness of UTAUT 2. Universities that have yet to implement digital library can comprehend undergraduates' needs better by considering all the significant factors to develop a digital library. The universities with the digital library may also notice the important features of the existing digital library that should be maintained and upgraded constantly so that they can fulfil undergraduates' requirements.

重塑行政人格——城管和谐执法的新路径探索

随着经济的快速发展和城市化进程的进一步推进,我国各大城市紧紧围绕建设和谐城市的主题,在改善城市面貌、维护社会稳定、提高服务水平等方面取得了长足进步,但是在建设和谐城市的过程中也出现诸多问题,一些城市失业人口、进城的农民工以及一些由于城市发展而失去土地的人员摊贩化、摊贩经营非法化,使街头摊贩管理成为城市管理的一个难题。在管理过程中常常出现暴力执法、流血冲突等不和谐的场面,这严重背离了构建和谐城市的宗旨。诚然,造成此类流血事件的原因是复杂的。在深入剖析当下城管执法存在的主要问题的基础上,提出从提高城管执法人员个体道德修养、健全相关的制度规范、构建健康的组织文化等方面来重塑其良好的行政人格的设想,试图探索一条实现城管部门和谐执法的新路径,以促进和谐城市的建设。
