Terrorist Population Dynamics Model

A system that includes a number of terrorist cells is considered. The cells can consist of one or more terrorists. The current number of terrorist cells is further denoted by N(t), where t is a current time counted from any appropriate origin. The objective is to find the evolution of the system in terms of N(t) and some interpretable parameters, such as the initial number of the terrorist cells N0=N(0), the cell disabling rate constant lambda (or the cell half-life t1/2), and the rate of formation of new cells P. The cost-effectiveness analysis, performed in the framework of the model, reveals that the effectiveness of disabling a terrorist cell is getting worse after 2-3 half-lives of a cell, which shows that if the anti-terrorist actions have not reached their goal during that time, the respective policy should be considered for revision, using the risk assessment consideration. Another important issue raised concerns balancing the efforts related to counterterrorism actions inside the system and the efforts protecting its borders. The respective data analysis is suggested and illustrated using simulated data.

略论国有商业银行资本充足率

商业银行抵御金融风险的能力和业务扩张的能力取决于资本实力。国际上的《巴塞尔协议》和我国《商业银行法》都规定商业银行资本充足率不得低于 8%。我国国有商业银行由于自我积累率低、筹资渠道单一、资产结构不合理等原因 ,资本充足率长期偏低 ,竞争劣势明显。为此 ,我国国有商业银行必须采取有效措施 ,尽快提高资本充足率 ,增强竞争力 ,主动迎接外资银行的挑战

薄环形相对论电子注介质切伦可夫脉塞

轴向电子注通过介质慢波系统，当波的相速略低于电子注的速度时就可产生相干的切伦可夫辐射，这一现象是一切行波管的基础。本文利用线性理论，通过自洽求解粒子连续性方程和相对论运动方程与麦克斯韦方程组，分析了薄环形相对论电子注介质切伦可夫脉塞的注波互作用，得到了完全描述其薄环形电子注作用的跳变条件，导出了描述其不稳定性的色散方程和注波互作用的同步条件，并求得了波增长率。

"马寅初面斥孔祥熙"辨析

潘伦在<马寅初先生面斥孔祥熙纪实>这篇回忆录中,详细叙述了在1939年秋中国经济学社年会上,马寅初当面斥责孔祥熙的史迹.此文被众多著述家作为信史加以引用,在有关马寅初、孔祥熙等研究领域产生了广泛影响.笔者经过细致考证,证实了历史上并无"马寅初面斥孔祥熙"之事件.     

Further results for parallel systems with two heterogeneous exponential components

In this paper, we investigate ordering properties of lifetimes of parallel systems with two independent heterogeneous exponential components with respect to likelihood ratio and hazard rate orders. Two sufficient conditions are provided for likelihood ratio and hazard rate orders to hold between the lifetimes of two parallel systems, respectively. Moreover, we extend the results from exponential case to the proportional hazard rate models. The results established here strength some of the results known in the literature. Finally, some numerical examples are given to illustrate the theoretical results derived here as well.     

试论中国房产税的功能发挥与立法改革

中国房产税目前应着重发挥其调控经济和控制房价的功能,即通过税收立法手段改变投资者及投机者的经济预期,以稳定房价并使房屋还原居住属性的真实面目。通过执行超额累进税率并充分扩大税基,来保护正常购房者的合理住房需求并抑制投资投机需求。同时,根据政策需要逐步由超额累进税率转变为较低的比例税率。
