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.     

牛心朴子草抗植物病毒组分的生物活性研究

牛心朴子草地上部分醇浸粗提物（H）对烟草花叶病毒（TMV）有高抑制活性。该草抗植物病毒有效组分是菲并吲哚是西定生物总碱（G），半中枯斑法测定（G）制剂对TMV，马铃薯Y病毒（PVY），和芜菁花叶病毒（TUMV）呈现高活性；用酶联免疫法（Elisa)测定(G）制剂对TUMV的最佳浓度防效，与枯斑法测定结果基本要符。（G）中含量最丰的（1）7－脱甲氧基娃儿藤碱（antofine)是该草活性最高的主组分，它在10^-6g/ml浓度的TMV抑制率达60％。     

BNT系纳米粉体的制备及微波特性研究

使用柠檬酸盐法成功制备出分散良好的颗粒状BNT系纳米粉体。经TEM和XRD分析,粉体的平均粒径约30 nm,其主晶相为Nd2Ti2O7,经1 300℃烧结成瓷后还出现了BaNd2Ti4O12相。此类材料具有良好的高频特性,用此类材料研制出的单片微波陶瓷电容器具有良好的微波特性。     

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.

试论《周易》研究中的两种误区

着重指出目前易学界在《周易》研究中出现的两个误区 :一是把《周易》迷信化、神秘化 ;二是把《周易》人为地现代化 ,用现代科学附会《周易》。这两种倾向都是违反科学精神的 ,它对我们民族科学思维的建立、科学方法的应用、科学水平的提高都是十分有害的。从历史及文化角度对此进行分析
