As the original system such as ITTC,etc.,is unsaf e ,inefficient and impracitcal in actual network environment,this paper brings u p a new distributed certification scheme,which although it generates key shares concentratively,it updates key shares distributedly,and so,avoids single-po in t failure like ITTC. It not only enhances robustness with Feldman verification and SSL protocol,but can also change the threshold (t,k) flexibly and robu stly,and so,is much more practical. In this work,the authors implement the prototype sy stem of the new scheme and test and analyze its performance.展开更多

Taking fruit dealers in Shizishan Street Farm market in Wuhan City as the research object,this paper introduced current operation situation of fruit dealers and made a descriptive statistical analysis on characteristics of operators,operation situation,and cognitive status. Besides,it introduced the concept of net cost-benefit ratio to reflect the operation benefits. From further analysis on the operation benefits of fruit dealers,it found that there is little difference in the costbenefit ratio between dealers in the farm market. The average net cost-benefit ratio was 11. 94%. Specifically,if the total cost is 100 yuan,the dealer can obtain 12 yuan net profit. In order to find out how cost factors affect the operation benefits,it established a regression model for cost factors and net cost-benefit ratio. According to the survey results,when the wholesale cost increases 10000 yuan,the cost-benefit ratio will increase by 1. 454 percentage points,thus increasing the wholesale investment is helpful for increasing the net cost-benefit ratio; when the loss cost increases 10000 yuan,the cost-benefit ratio will increase by 7. 501 percentage points,thus the dealers can increase the operation benefits through controlling the loss cost and reducing the operation cost. Finally,it came up policy recommendations from the perspective of government and operators.展开更多

Sales team managers are anxious to know what factors influence their salespeople in order to encourage sellers to behave ethically. This article proposes to study the factors influencing the ethical behavior of the sellers and especially sellers in auto dealerships. A questionnaire was given to salespeople from auto dealerships using the scenario method to measure the ethic. It has proposed an eight-step methodology, based on the thought of Aristotle, which, to people＇s knowledge, is the only measure to operationalize ethics. Scenarios have been then created, which seem to be the best method to measure salespeople＇s ethics behavior. Then a classical method was used to measure seller＇s performance. The results can show that ethic is a personal value which, when high, allows sellers to better understand the values of the company. The existence of formal ethical codes also permits sellers to behave in an ethical way.展开更多
