The responsibility to protect,as enshrined in article 4 of the Constitutive Act of the African Union

This paper assesses the emergence of the responsibility to protect (R2P) as an international relations norm. Following a brief discussion of the genesis of this norm, it assesses the key aspects of R2P. It then examines the Constitutive Act of the African Union (2000) to analyse the extent to which R2P is enshrined and implicated in this document. The paper also discusses the extent to which the AU has sought to implement R2P through its commitment to promote peace around the continent where there is a crisis. It concludes with a discussion of whether the AU is in fact committed to R2P.     

The United Nations-African Union Mission in Darfur: Implications and prospects for success

With the security situation in Darfur remaining grim, the international community passed United Nations Security Resolution 1769 that authorised a more robust peacekeeping force. This article addresses the security concerns motivating the United Nations-African Union Mission in Darfur (UNAMID), highlights the mandate and implications of the force, and compares the potential command and control issues to the experiences of the Somalia intervention in the 1990s. It closes by analysing the prospects for success of the intervention and offering some limited recommendations on ways to mitigate the risks associated with the peacekeeping effort.     

Auxiliary Force or National Army? Afghanistan's ‘ANA’ and the Counter-Insurgency Effort, 2002–2006

Afghanistan's fifth effort to form a central army started in 2002, following the fall of the Taleban regime. Mainly run by the US armed forces, the formation of the so-called ‘Afghan National Army’ run into several difficulties, ranging from initially slow recruitment, low educational level of troops and officers, high attrition rates. As the new army began to take shape, it lacked many of the characteristics which had been associated by the promoters with a ‘national’ army. It also showed a low level of commitment and a lax discipline. As of 2006, it looked more like an auxiliary force at the service of the US army and its allies than like a ‘national’ army.     

Upper and lower bounds for a pattern bombing problem

This paper includes two simple analytic formulas for kill probability that are applicable in circumstances where shots should be fired in a pattern. The two formulas bracket the maximum kill probability achievable with an optimal pattern. The upper bound corresponds to an optimal nonfeasible pattern, and the lower bound to a nonoptimal feasible pattern.     

(R.Q) inventory problem with unknown mean demand and learning

We address a single product, continuous review model with stationary Poisson demand. Such a model has been effectively studied when mean demand is known. However, we are concerned with managing new items for which only a Bayesian prior distribution on the mean is available. As demand occurs, the prior is updated and our control parameters are revised. These include the reorder point (R) and reorder quantity (Q). Deemer, taking a clue from some earlier RAND work, suggested using a model appropriate for known mean, but using a Compound Poisson distribution for demand rather than Poisson to reflect uncertainty about the mean. Brown and Rogers also used this approach but within a periodic review context. In this paper we show how to compute optimum reorder points for a special problem closely related to the problem of real interest. In terms of the real problem, subject to a qualification to be discussed, the reorder points found are upper bounds for the optimum. At the same time, the reorder points found can never exceed those found by the Compound Poisson (Deemer) approach. And they can be smaller than those found when there is no uncertainty about the mean. As a check, the Compound Poisson and proposed approach are compared by simulation.
