The National Movement for the Liberation of Azawad factor in the Mali crisis

Mali has been a battleground for more than a year now. While the armed conflict came in the aftermath of the Libyan crisis that left the regional security environment depleted, it also served as a catalyst for the collapse of state authority in Mali. This created conditions conducive for the proliferation of, and attacks by, radical religious armed groups in the northern regions of the country, including the Tuareg armed movement: the National Movement for the Liberation of Azawad (MNLA). But, far from being a new phenomenon, the Tuareg-led armed insurrection in the northern regions is as old as the post-colonial Malian state, and continues to pose tremendous challenges in West Africa and the Sahel region for both regional and extra-regional actors. The recent crisis in the Sahel region is seen as one of the most serious since the end of the Cold War, with anticipated dire long-term impacts on the security of the region and beyond. While attention is predominantly focused on defeating the jihadist groups that have threatened the survival of the Malian state, one must not lose sight of the fact that the ‘Tuareg Factor’, as represented by the rebellion launched by MNLA, remains critical both in terms of appreciating the deterioration of the situation and attempting to frame long-lasting solutions. The paper argues that the Tuareg's persistent recourse to rebellion against Bamako needs to be understood within a historical trajectory that takes into consideration three key parameters: firstly, the post-colonial state in Mali and its African leadership's relations with the descendants of the Tuareg communities; secondly, the amalgamation created by the so-called war on terror; and, finally, the contradictions of the democratisation process of the 1990s.¹1 This article is based on field research carried out between 2008 and 2013 on the ‘Resurgence of Tuareg-led Rebellions’.     

Some order relations in closed networks of queues with multiserver stations

Consider a closed network of queues of the “product-form” type, where each station has s servers (s ≥ 1 is identical for all stations). We show that the throughput function of the network is Schur concave with respect to the loading of the stations and arrangement increasing with respect to the assignment of server groups. Consequently, different loading/assignment policies can be compared under majorization/arrangement orderings and their relative merits decided according to the yields of throughput. The results can be used to support planning decisions in computer and production systems which are modeled as closed networks of queues.     

GLOBALIZING REAGAN'S INF TREATY

When it was concluded more than a quarter century ago, the Intermediate-Range Nuclear Forces (INF) Treaty between the United States and the Soviet Union was hailed as a disarmament watershed, eliminating entire classes of nuclear missiles from the arsenals of the arms-racing Cold War superpowers. Over the intervening decades, there have been repeated calls to convert this legacy treaty into a new international norm against nuclear and missile proliferation by broadening it into a global prohibition on ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. Indeed, variations on this proposal have been knocking around for so long and with so little success that the entire concept has come to be dismissed by many knowledgeable insiders as something of a farce. Looking beyond its inauspicious pedigree, however, this viewpoint suggests that the time is opportune for Washington to give the idea a fresh look. Drawing on a detailed review of the history of “Global INF” and an analysis of the contemporary context, the author recommends that the Obama administration consider a simple declaratory approach that promises modest initial benefits, avoids previous and foreseeable pitfalls, and plausibly lays a solid foundation for achieving significant long-term progress.     

Probability inequalities via negative dependence for random variables conditioned on order statistics

Distributions are studied which arise by considering independent and identically distributed random variables conditioned on events involving order statistics. It is shown that these distributions are negatively dependent in a very strong sense. Furthermore, bounds are found on the distribution functions. The conditioning events considered occur naturally in reliability theory as the time to system failure for k-out-of-n systems. An application to systems formed with “second-hand” components is given.     

Strength in Numbers: The Labour Government and the Size of the Polaris Force

Previous historical accounts have simplified the Labour government's decision to commission a four-boat strategic nuclear deterrent, or ‘Polaris force’, in early 1965. Utilising previously classified sources, this article shows that a number of key strategic concerns led the decision-making process. Nevertheless, broader economic and diplomatic considerations were also important in determining the size of the Polaris force. A tremendous balance of payments deficit and ongoing debates regarding levels of conventional and nuclear involvement in NATO certainly influenced the government's final decision. Moreover, competing strategic and economic interests resulted in continued debate throughout the decision-making process.
