As an institution of state, the military in Lesotho was marred by controversy and steeped in intrigue from the start. For much of the post-colonial period the military was used as a politicised and partisan tool, which even seized power and governed in its own name. The current problem, as this brief history aims to demonstrate, is essentially two-pronged. It involves putting in place structures, mechanisms and philosophies designed to promote the military's acceptance of civil supremacy. The process should also include alterations to political society's perception of the military as a tool to be used in partisan games that almost always have calamitous outcomes. Lesotho's political development is classified in this article into four broad phases and the type of civil-military relations is assessed under each phase. The reasons for the military coup in 1986 are analysed, the emergence of a democratic order and the challenges facing this order are highlighted, and the reform measures that have thus far been instituted are evaluated. The essay concludes with a few projections into the future course of events. 相似文献

The disappointingly slow pace of progress on efforts to prevent proliferation, reduce nuclear weapons, and eliminate nuclear risks has many causes. The factor that might be easiest for individuals in the arms control and nonproliferation community to change stems from their own ambivalence about major questions that must be addressed on the road to reducing the number of nuclear weapons in the world to zero. This essay explores how ambivalence about four key issues—strategic stability, alliance relations, institution-building, and nuclear energy—often leads community members to take positions that play well at home and within their like-minded group but raise unintended impediments to achieving their own long-term goals. The author suggests alternative ways to handle these questions to improve the prospects for domestic and international agreement on practical measures that would eliminate, not perpetuate, nuclear risks. 相似文献

In a recent paper in this journal, Wijewerra and Webb study the connection between military spending and gross domestic product (GDP) in a group of five South Asian countries, finding a small but statistically significant positive relationship between military spending and GDP. This paper reviews their approach and proposes an alternative which tries to deal with the problems of omitted variables and variable construction. It finds, in contrast, that a higher share of military spending in GDP is associated with lower growth of GDP per capita. 相似文献

In interval scheduling, not only the processing times of the jobs but also their starting times are given. This article surveys the area of interval scheduling and presents proofs of results that have been known within the community for some time. We first review the complexity and approximability of different variants of interval scheduling problems. Next, we motivate the relevance of interval scheduling problems by providing an overview of applications that have appeared in literature. Finally, we focus on algorithmic results for two important variants of interval scheduling problems. In one variant we deal with nonidentical machines: instead of each machine being continuously available, there is a given interval for each machine in which it is available. In another variant, the machines are continuously available but they are ordered, and each job has a given “maximal” machine on which it can be processed. We investigate the complexity of these problems and describe algorithms for their solution. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007 相似文献
