上海股票市场波动实证性研究:2001--从交易方式角度透视

我国股票市场上的交易方式有两种,即集合竞价和连续竞价,交易方式的差异会对股价的波动性产生影响,而市场的波动性对股票市场而言是双刃剑,因此从交易方式角度探求股市的适度波动成为理论工作的一个重心.本文以上海股票市场为研究对象,针对2001年的全部交易数据进行实证研究.结果表明,集合竞价形成的开盘价格收益率的方差大于连续竞价形成的收盘价格收益率的方差,其原因在于集合竞价与连续竞价相比,其交易过程的透明度差和交易指令具有不可更改性,据此,从交易制度上提出政策建议.     

Labor relations and technological change at Canadian Pacific Railway

There was a time in this fair land when the railroad did not run When the wild majestic mountains stood alone against the sun Long before the white man and long before the wheel When the green dark forest was too silent to be real For they looked into the future and what did they see They saw an iron road running from the sea to the sea Bringing the goods to a young growing land All up through the seaports and into their hands From “Canadian Railroad Trilogy” by Gordon Lightfoot The authors thank CPR managers and union officials representing CPR employees for their cooperation and patience in explaining the intricacies of the railroad industry. Special appreciation is extended to Jason Copping, Labour Relations Manager, for his facilitating our initial access to the company.     

Ka波段二倍频器的研究与设计

利用反向并联二极管对的二倍频原理,设计了Ka波段二倍频器。用高级设计系统ADS设计软件包的射频设计软件对二倍频器的电路进行了模型设计和仿真分析,并对设计出的二倍频器进行了整体优化,研制了Ka波段的二倍频器;在整个Ka波段内的变频损耗为11.2±1.8 dB,减少了设计的理想模型与实际参数的偏差。     

The Texaco racial discrimination case and shareholder wealth

We analyze the wealth ejfects of the Texaco racial discrimination lawsuit both on the shareholders of Texaco and its major U.S. competitors. Employing a comprehensive data set which included every case docket entry and every Wall Street Journal article on the case as an experimental stimulus, our findings suggest that the overall cost of the case to Texaco shareholders exceeded $500 million, that Texaco's tribulations had little, if any, impact on the share prices of its major competitors, and that Wall Street Journal coverage of the case was highly correlated with significant changes in Texaco stock prices. This last finding provides significant support for Hite 's suppostion that newspaper editors “key ” on ex post stock price changes in selecting the events to be covered in the next day's edition. The authors are grateful to Kee Chung for helpful comments on earlier drafts and also acknowlege the help-ful assistance of the staff of the law library at the Cecil C. Humphreys School of Law at The University of Memphis.

中国古代哲学与自然科学的关系史撷要及其历史启示

本文从春秋战国、秦汉、三国两晋南北朝、隋唐宋元、明清五个分期对中国古代哲学与自然科学的关系史进行了考察。哲学的繁荣可以促进科学的繁荣 ,哲学的凋敝也容易压制科学的创新 ;哲学的发展与科学的发展在历史上往往是耦合的 ;哲学与科学的分离容易导致哲学的畸形发展 ;科学脱离哲学将缺乏指向性和方法论指导     

A Review of Kyoto Protocol Adoption in Russia: Joint Implementation in Focus

Russia’s role in ‘animation’ of the Kyoto Protocol was crucial. Its initial vacillation on ratification was predominantly due to political bargaining with the EU. Domestic economic rationales [i.e. impacts of emission trading and Joint Implementation (JI) projects] were important to a much lesser extent and environmental motives did not seem to play any role in the decision. Since the Protocol entered into force, there have been significant delays in complete establishment of policy implementation frameworks, which are necessary for Russia to start benefiting from JI and emission trading. Only recently, in 2007, have GHG inventories and a national registry been established and the responsibilities for implementation of the Protocol and JI among the government departments have been distributed only to a certain extent. Some constraints hindering JI projects, such as vague legislation, an unfavourable economic climate, lack of commitment to JI projects, corruption, xenophobia, state and agency ‘capture’ still remain.
