‘Responsibility to protect’ and the African Union: Assessing the AU’s capacity to respond to regional complex humanitarian and political emergencies

Despite its many institutional and political weaknesses and limitations, the African Union (AU) has been developing a variety of tools and mechanisms to respond effectively to complex disasters and emergencies (both natural and manmade) by building up a comprehensive regional security architecture. Furthermore, it has become the first and only regional or international organisation to enshrine the principle of ‘responsibility to protect’ (R2P) in its Constitutive Act. This regional approach to and formal endorsement of the R2P principle allowed it to assume a particular place in the promotion of peace and security in its area. This article aims to critically assess the effectiveness of the AU on the African continent by exploring its real capacity in preventing and responding to emergencies and violent conflicts, and therefore in rendering the principle of R2P operational. The article argues that the formalisation of principles does not necessarily mean their effective implementation. The organisation's use of the R2P principle is also greatly conditioned by internal and external factors.

谈高校校报思想政治教育的作用

高校校报既是高校思想宣传工作的重要阵地,又是高校进行思想政治教育的重要平台。深入分析、挖掘校报的思想政治教育作用,对校报提高办报质量,有针对性地为高校发展提供舆论支持具有深远意义。只有充分发挥高校校报在思想政治工作中的作用,才能稳固校园主流媒体的地位。     

思想政治教育对高校突发事件的防范功能研究

为维持高校和社会的和谐稳定,必须防范高校突发事件的发生。思想政治教育对高校突发事件有着特殊而重大的防范功能,它不但能为防范突发事件提供可靠的思想保证和精神动力,而且其本身就是防范突发事件的重要手段。思想政治教育在思想引导、心理干预、利益协调、情绪宣泄、预防文化教育和预警等方面都具有对高校突发事件的防范功能。

剖分T型钢轴心压杆的弯扭屈曲

《钢结构设计规范》（GB50017—2003）认为单轴对称的T型钢轴心压杆绕对称轴的稳定性是弯扭失稳问题。本次试验发现,剖分T型钢轴压杆有必要做弯扭屈曲验算,计算方法采用换算长系比法。     

线性相依风险下的超额赔款再保险

本文从保险人的角度研究对两类相依风险的超额赔款再保险的最优自留额问题。考虑指数效用函数的货币期望效用原则和自留累积损失的调节系数原则,得到关于这两个问题的最优解的方程。     

光顺样条函数的再生核表示与计算

光顺样条是散乱数据拟合的理想函数,是噪声数据最优平滑的重要工具。因此,光顺样条的数学表示和计算的研究具有重要的意义。本文在一般的线性微分算子和线性泛函的情况下讨论光顺样条函数的构造和计算,通过构造一个适当的再生核Hilbert空间,使得所讨论的微分算子光顺样条成为该空间中的最小范数问题,再利用投影理论建立了光顺样条函数的再生核表示方法,并得到了插值偏差表达式。作为特例,还给出了奇次多项式光顺样条函数新的简洁的计算方法。     

The effects of model parameter deviations on the variance of a linearly filtered time series

We consider a general linear filtering operation on an autoregressive moving average (ARMA) time series. The variance of the filter output, which is an important quantity in many applications, is not known with certainty because it depends on the true ARMA parameters. We derive an expression for the sensitivity (i.e., the partial derivative) of the output variance with respect to deviations in the model parameters. The results provide insight into the robustness of many common statistical methods that are based on linear filtering and also yield approximate confidence intervals for the output variance. We discuss applications to time series forecasting, statistical process control, and automatic feedback control of industrial processes. © 2010 Wiley Periodicals, Inc.

Analytic solution for the nucleolus of a three‐player cooperative game

The nucleolus solution for cooperative games in characteristic function form is usually computed numerically by solving a sequence of linear programing (LP) problems, or by solving a single, but very large‐scale, LP problem. This article proposes an algebraic method to compute the nucleolus solution analytically (i.e., in closed‐form) for a three‐player cooperative game in characteristic function form. We first consider cooperative games with empty core and derive a formula to compute the nucleolus solution. Next, we examine cooperative games with nonempty core and calculate the nucleolus solution analytically for five possible cases arising from the relationship among the value functions of different coalitions. © 2010 Wiley Periodicals, Inc.
