刘文 《山西财经大学学报(高等教育版)》2003,(2):1-4

章用产权理论研究教师人力资本,分析教师人力资本产权特性,认为教师的人力资本产权具有个人占有的天然性、使用的增值性、价值度量的不确定性、价值实现的自发性、产权残缺时的自贬性、收益的外部性和长期性。  相似文献   

政府应致力于缩小农村数字鸿沟     

文晓灵 《当代教育论坛》2003,(11):12-14

当前我国城乡存在着巨大的数字鸿沟。数字鸿沟的存在阻碍着“三农”问题的解决：导致出现政治权力的不平等；缺乏致富奔小康的信息手段；进一步拉大文明差距；不利于农村城镇化进程。政府首先应承担起消弥农村数字鸿沟的重任，同时要抓住数字机遇，推进教育信息化，以跨越数字鸿沟。  相似文献

从秦汉奴婢奸罪窥探其法律地位     

文霞 《首都师范大学学报(社会科学版)》2007,(2):16-21

秦汉奴婢所犯奸罪主要有强奸、和奸、禽兽行三种。秦汉法律对犯奸罪的奴婢的惩罚要重于其他人，而且会因受害者身份不同而不同。一般而言，法律对奴婢在家庭内部所犯奸罪惩罚最重，反映出秦汉家庭中主奴之间严格的等级界限，以及法律对家庭内部伦理关系的维护；相比之下，对奴婢在家庭关系之外所犯奸罪惩罚较轻，这在一定程度上反映出秦汉时期较为开放的社会风俗。秦汉时代社会等级制度尚未严格化，这使得奴婢的身份较易得到改变。  相似文献   

CdS/SiO2 nanowire arrays and CdS nanobelt synthesized by thermal evaporation     

YU Ling-min ZHU Chang-chun FAN Xin-hui QI Li-jun YAN Wen 《浙江大学学报(A卷英文版)》2006,7(11):1956-1960

INTRODUCTION The richness of fundamental phenomena and the potential applications in nano-technologies has ar- oused rapidly growing interest in nano-dimensional materials. Quasi-one-dimensional (1D) nano-semi- conductors in the form of nanowires and nanoribbons have recently been successfully fabricated in many laboratories and by many methods (Wu et al., 2004; Yang et al., 2005; Gan et al., 2004; Soumitra et al., 2006). To synthesize CdS nanowires, people have developed a series of sy…  相似文献

Development and validation of a model for predicting wheel wear in high-speed trains     

Gong-quan Tao  Xing Du  He-ji Zhang  Ze-feng Wen  Xue-song Jin  Da-bin Cui 《浙江大学学报(A卷英文版)》2017,18(8):603-616

In this paper, we present a comprehensive model for the prediction of the evolution of high-speed train wheel profiles due to wear. The model consists of four modules: a multi-body model implemented with the commercial multi-body software SIMPACK to evaluate the dynamic response of the vehicle and track; a local contact model based on Hertzian theory and a novel method, named FaStrip (Sichani et al., 2016), to calculate the normal and tangential forces, respectively; a wear model proposed by the University of Sheffield (known as the USFD wear function) to estimate the amount of material removed and its distribution along the wheel profile; and a smoothing and updating strategy. A simulation of the wheel wear of the high-speed train CRH3 in service on the Wuhan-Guangzhou railway line was performed. A virtual railway line based on the statistics of the line was used to represent the entire real track. The model was validated using the wheel wear data of the CRH3 operating on the Wuhan- Guangzhou line, monitored by the authors’ research group. The results of the predictions and measurements were in good agreement.  相似文献

计算网格中基于博弈论的改进算法机制     

林雯  郁松年  肖齐 《上海大学学报(英文版)》2007,11(1):68-68

Computational grids(CGs)aim to offer pervasive access to a diverse collection of geographically distributed resources owned by different self-interested agents or organizations.These agents may manipulate the resource allocation algorithm in their own benefit,and their selfish behavior may lead to severe performance degradation and poor efficiency. In this paper,game theory is introduced to solve the problem of barging for resource collection in heterogeneous distributed systems.By using the Cournot model that is an important model in static and complete information games,the algorithm is optimized in order to maximize the benefit.It can be seen that the approach is more suitable to the real situation and has practical use.Validity of the solutions is shown.  相似文献
