Impact of International Networks on Standardization Process in Banking Industry： Example of Secure Electronic Transaction （SET） Initiative

The purpose of this article is to present and interpret the case study of the secure electronic transaction （SET） scheme of Internet security, as an illustration of the necessary construction of interoperability solutions for financial services. The interpretation of case data with actor network theory （ANT） provides an illustration of power coalitions among banks to create a de facto standard for transnational electronic payment security on the Internet. After a step of protecting its political interests and well-known technological solutions, the coalition understands that its mission becomes a matter of life and death for its members： Brand-new currency has been invented on the Web and one could develop business and monetary transactions without the banks. This interpretative stage tells us much about the transnational mechanisms of regulation and standardization as well as the ＂translation＂ steps regarding these transnational organizations. However, an additional step has to be added to this interpretative step, a step of framework construction. The aim is to help managers of the transnational firms involved in regulations and standardization to anticipate the evolutions and make relevant decisions. The framework has three distinctive characteristics： the ability to help conception, the ability to help conceive problems ＂ex ante＂, and the ability to facilitate collective conception of strategic maneuvers.

山西王家岭煤矿底板奥灰水突水危险性评价

我国是受水害最严重的国家,奥灰水突水是我国很多煤矿在安全生产中急待解决的问题。山西王家岭煤业集团公司王家岭煤矿就面临着开采9号煤层底板奥灰水突水威胁的安全问题。结合王家岭煤矿实际钻孔数据,运用突水系数法、多层叠加抗压强度比值系数法分别对9号煤层进行突水危险性预测,并进行相互对比,根据计算所得结果得出9号煤层底板易发生突水区。

The institution efficiency of stock price limits： An experimental analysis on the two stocks market with continuous bid

Price limits in product market have been discarded in classic microeconomics. However, price limits affect the trade behavior of the same agent, since agents in the stock market change their trade status frequently. Due to the controversy on the institution effectiveness of the price limits in stock market, this paper design an experimental market with two stocks with continuous bid, in which we investigate the impact of the price limits on the stock market. The results show that the price limits moderate the price volatility within and between the trades periods, thus can stabilize stock price. In addition, price limits, when measured by traditional approach, restrain the fluidity of the market, reduce the volatility of transaction shares and maintain durative of fluidity. While volatility-based fluidity measurements show that the fluidity is enhanced significantly in stock market with price limits.
