大学治理结构中的委托-代理问题--当前中国公立大学委托代理关系若干特点分析   总被引：9，自引：0，他引：9  

孙天华 《北京大学教育评论》2004,2(4):29-33

本文在吸收其他文献的基础上 ,试图把委托代理理论框架引入到对中国公立大学治理结构和管理绩效的分析上来。在公立大学多级委托代理关系的链条上 ,第一层级代理人的行为选择与委托代理关系中隐形的激励契约密切相关。公立大学的产权关系与它特殊的目标、功能和使命 ,对代理成本的度量产生十分重要的影响。在某一环节上 ,委托人与代理人的非正常合作会改变正常情况下委托人与代理人目标函数不一致的现象 ,且代理人若不在正常的市场上依照市场机制进行挑选 ,大学的运行成本就会居高不下。解决我国公立大学中的委托—代理问题 ,需要重新构建合理的委托代理关系 ,这方面有赖于大学治理结构的突破 ,也有赖于政府新的制度供给。  相似文献

The characteristics and self-time-delay synchronization of two-time-delay complex Lorenz system     

Baojiang Sun  Min Li  Fangfang Zhang  Hui Wang  Jian Liu 《Journal of The Franklin Institute》2019,356(1):334-350

Time-delay is frequently encountered in a variety of practical chaotic systems, such as chaos-communication. The behaviours of time-delay chaotic system are greatly different from those of the original system. Self-time-delay synchronization (STDS) implies that the synchronization between the time-delay system and the original system while maintaining the structure and parameters of systems unchanged, thus these various problems produced by time-delay in practice are avoided. Firstly, we investigate the characteristics of two-time-delay complex Lorenz system. Then we take one-time-delay and two-time-delay complex Lorenz system as examples, and design their controllers to realize STDS. One-time-delay complex Lorenz system is a special case of two-time-delay. Numerical simulations verify the validity of the STDS controllers. The controllers only involve error, and it is easy to realize in practice. Moreover, the time-delay chaotic system exhibits highly stochastic behaviors and unpredictable properties, which can be applied to chaos-communication and enhance the security of communication.  相似文献

Increased foot-stretcher height improves rowing performance: evidence from biomechanical perspectives on water     

Yang Liu  Binghong Gao  Jiru Li  Zuchang Ma  Yining Sun 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(2):168-179

Abstract

The aim of this study was to investigate whether changes on foot-stretcher height were associated with characteristics of better rowing performance. Ten male rowers performed a 200 m rowing trial at their racing rate at each of three foot-stretcher heights. A single scull was equipped with an accelerometer to collect boat acceleration, an impeller with embedded magnets to collect boat speed, specially designed gate sensors to collect gate force and angle, and a compact string potentiometer to collect leg drive length. All sensor signals were sampled at 50 Hz. A one-way repeated measures ANOVA showed that raising foot-stretcher position had a significant reduction on total gate angle and leg drive length. However, a raised foot-stretcher position had a deeper negative peak of boat acceleration at the catch, a lower boat fluctuation, a faster leg drive speed, a larger gate force for the port and starboard side separately. This could be attributed to the optimisation of the magnitude and direction of the foot force with a raised foot-stretcher position. Although there was a significant negative influence of a raised foot-stretcher position on two kinematic variables, biomechanical evidence suggested that a raised foot-stretcher position could contribute to the improvement of rowing performance.  相似文献
