WIN7平台ARP网络攻防

为了确认Windows7平台下ARP欺骗攻击的防御能力,利用arpfree命令行工具,模拟三种不同的ARP网络攻击,分析攻击结果及对Windows7的性能影响,并检测ARP防火墙在面对以上攻击时的防御能力。未安装防火墙的Windows7可以防御ARPRequest攻击,但三种攻击都会显著的占用带宽资源。Windows7在防火墙的支持下,可以防御三种攻击,只能发现并阻断ARPRequest攻击,两种攻击仍然会占用大量用户的带宽与CPU资源。

Trading frequency and volatility clustering

Volatility clustering, with autocorrelations of the hyperbolic decay rate, is unquestionably one of the most important stylized facts of financial time series. This paper presents a market microstructure model that is able to generate volatility clustering with hyperbolically decaying autocorrelations via traders with multiple trading frequencies, using Bayesian information updates in an incomplete market. The model illustrates that signal extraction, which is induced by multiple trading frequencies, can increase the persistence of the volatility of returns. Furthermore, we show that the volatility of the underlying time series of returns varies greatly with the number of traders in the market.

Unsafe sex,AIDS and development

The AIDS-fighting communities have spent their limited resource on improving people’s awareness of the risk of contracting AIDS, and yet these programs have not resulted in sustained behavior change. This paper offers a possible explanation of why agents in poor countries choose to engage in more unsafe sexual activities when they are perfectly cognizant of the risk involved. It is shown that agents may rationally choose to do so when they are poor, since future is not attractive due to poverty and agents care more about current-period utility. Our results indicate that safe sexual practice is essentially a “normal good” and that development may be key to reduce the HIV infectivity by modifying agents’ sexual behavior. The model is then extended to consider the role of public health expenditure. We find that the relationship between protected sexual activity and development is no longer monotonic: unsafe sexual activity may increase slightly after a critical level of development has been reached. Finally, we examine the impacts of AIDS on development by considering individual’s saving decision. It is shown that agents tend to save more and accumulate more capital when economy grows.     

文化语境在语词翻译中的重要作用

论存款机构的保密义务

存款机构对存款人负有保密义务，这种义务来源于存款合同中的默示条款理论，存款机构的保密义务不是绝对的，存在有例外情形，我国现行法律有关存款机构保密义务的规定缺乏系统性、操作性，亟待完善。
