高校网上招生系统的后续开发与研究

针对目前院校端网上招生录取系统存在的局限性,文章详细介绍了高校网上招生后续开发管理系统的功能,讨论了系统实现中的关键技术及实现方法,指出该系统采用分布式计算技术,建立基于组件的3层C/S模型的体系结构,具有高效性、可伸缩性、开发周期短、安全性高的特点。     

Java语言的特点与C^＋＋语言的比较

Java语言是一门很优秀的语言,具有面向对象、与平台无关、安全、稳定和多线程等优良特性,是目前软件设计中极为健壮的编程语言.Java已成为网络时代最重要的语言之一.与C++语言比较,Java是一种更纯粹的面向对象程序设计语言.     

将Python嵌入到C/C++应用程序中的编程方法

Python是一种面向对象的语言.本文介绍了怎样在不同的层次上将Python编译器作为一种扩展语言嵌入到用C/C++编写的应用程序之中.嵌入了Python的C/C++应用程序可以完成某些Python特有的功能.文章也讲述了如何扩展嵌入的Python使其获得应用程序本身的功能.最后,讲述了怎样使链接到静态库的应用程序获得动态扩展.     

B to C交易中消费者信任的生成机理研究

基于TRA、TPB和ETC等理论的扩展模型和Mcknight等人对信任的系统研究，构建出信任生成机理基础框架。同时，参考网上信任生成的周期说、因素说和DTR模型，提出由五条主线、一定的交互关系和大量影响因素组成的网上消费者信任生成机理综合模型，以期为理论研究和实践应用提供借鉴。     

4P、4C与4R:交易费用经济学的视角

4P是经典营销理论的核心内容之一。随着经济、文化和技术的全球化与区域化不断发展,市场竞争异常激烈,顾客在大部分领域取得了绝对的选择权,营销理论随之出现了4C和4R等“崭新”内容。从交易费用经济学的角度看,4C和4R不是对4P的替代,而是一种重要补充和发展。     

论在中国B2C发展的若干问题

我国电子商务的环境在不断改善,接受网上购物方式的消费者越来越多.但2001年中国B2C并没有表现出太多令人欣喜之处,甚至部分曾经领先的电子商务网站不得不面对生死存亡的抉择.造成这种现状的原因不仅仅是电子商务整体的一些原因,也包括一些影响B2C发展的特有原因.如市场发育问题、互联网的环境和条件问题、信用制度完善的问题、物流配送问题、立法问题、具体经营问题等.这些瓶颈若不能得到合理的解决,对于电子商务发展的影响将会是巨大的.     

Are Co-integrated Stock Prices Consistent with the Efficient Market Hypothesis?

This paper responds to the unsatisfactory argument that there is no correspondence between co-integration and the efficient market hypothesis. A law of one co-integrating vector of prices is proposed for the exchange rate and domestic and overseas stock prices. Markets must therefore be efficient in long-run equilibrium because no arbitrage opportunities exist. However, arbitrage activity via the disequilibrium error correction allows above-average (risk-adjusted) returns to be earned in the short run. The elimination of these arbitrage opportunities means that stock market inefficiency in the short run ensures stock market efficiency in the long run.     

Production, trade, prices, exchange rates and equilibration in large experimental economies

We study market equilibration in laboratory economies that are larger and more complex than any that have been studied experimentally to date. Complexity is derived from the fact that the economies are “international” in economic structure with multiple input, output, and foreign exchange markets in operation. The economies have twenty-one markets and due to the fact that they have roughly fifty agents, the economies are characterized by several hundred equations. In spite of the complexity and interdependence of the economy, the results demonstrate the substantial power of the general equilibrium model of perfect competition to predict the direction of movement of market-level variables. Empirical patterns in the convergence process are explored and described.     

A note on cheap talk and burned money

Austen-Smith and Banks [Cheap talk and burned money, J. Econ. Theory 91(1) (2000) 1-16] study how money burning can expand the set of pure cheap talk equilibria of Crawford and Sobel [Strategic information transmission, Econometrica 50(6) (1982) 1431-1451]. I identify an error in the main Theorem of Austen-Smith and Banks, and provide a variant that preserves some of the important implications. I also prove that cheap talk can be influential with money burning if and only if it can be influential without money burning. This strengthens a result of Austen-Smith and Banks, but uncovers other errors in their analysis. Finally, an open conjecture of theirs is proved correct.
