In this paper homomorphisms are used to define four new parameters of a graph, which have to do with minimum walks in graphs satisfying certain conditions. Several bounds and exact equations are obtained for two of these parameters; a third parameter is seen to be closely related to the Traveling Salesman Problem and the question of whether a given graph is Hamiltonian. 相似文献

ABSTRACTThis article systematically assesses the 2014 Afghanistan Presidential Election, the first transfer of power from President Hamid Karzai to an elected successor, using provincial voting data as well as explicit data from polling centers. The analysis finds unusual voting results in the April election, where no candidate received 50%+1 votes required by the Afghan constitution, versus the voting results realized for the June ‘runoff election.’ As in other Afghan voting analyses, this article finds voting based on ethno-linguistic preferences, and interestingly found Dr. Ashraf Ghani receiving almost all the swing votes in the runoff election even though the other leading candidate from the April election all endorsed Dr. Abdullah Abdullah. More importantly, however, the research presented here clearly finds extremely strange voting patterns. For example, the polling data center analysis finds 606 polling places where Ghani received all 600 votes and Abdullah received none and another 900 polling centers that gave virtually all its votes to Ghani. These results in combination with other analyses raise the very real possibility that the election results were illegitimate. The article concludes with a discussion of the implications of the research to future Afghan elections and their processes as well as to the long-standing conflict in the country. 相似文献

This article provides an in-depth examination and analysis of the 2006–2009 Tuareg rebellion in Mali and Niger. It identifies the underlying reasons behind the rebellion, explores contrasting counter-insurgency (COIN) strategies employed by the two governments, and presents some lessons learned. While both COIN approaches ultimately produced similar peace settlements, the article argues that the Malian strategy of reconciliation combined with the selective use of force was far more effective than the Nigerien iron fist approach at limiting the size and scope of the insurgency and producing a more sustainable peace. It concludes by looking at the role of external actors, particularly the United States, and how the failure to internationalize the conflict was actually more beneficial to the local COIN effort, as well as to the longer strategic interests of the United States in the region. 相似文献

US military operations are increasingly conducted within urban environments and with these operations come the risk of increasing the number of civilian casualties and infrastructure damage. The use of non-lethal weaponry, such as directed-energy weapons, is one method for minimizing collateral damage. This method enables US military forces to effectively fight within urban environments through force escalation capabilities. Using a series of historical examples and future scenarios for urban warfare, this article highlights deficiencies affecting military capabilities in military urban operations, addresses the consequences of collateral damage, assesses the effectiveness of directed-energy weapons in military urban operations and encourages further funding, research and integration of non-lethal weaponry, such as directed-energy weapons, within the US military. 相似文献

Offsets are a growing feature of international trade in defence equipment. This article assesses the economics of offsets and outlines UK offsets policy. There is a lack of empirical work in the field and the article presents the results of a survey of UK firms’ experience of their involvement in offsets against UK imports of defence equipment. There is also a case study of the AWACS offset programme and an evaluation of policy implications. 相似文献

This paper examines partition as a solution to ethnic civil wars and modifies the ethnic security dilemma, suggesting that strong state institutions are more important than demographically separating ethnic groups to achieve an enduring peace. The paper starts with a puzzle: if ethnic separation is required for peace, how do some partitions that leave minorities behind maintain peace? The paper compares post-partition Georgia–Abkhazia, which experienced violence renewal within five years of the partition, with post-partition Moldova–Transnistria, which maintained peace. Both countries had ‘stay-behind’ ethnic minorities. The paper also disaggregates and compares the territories within post-partition Abkhazia, which contain ethnic Georgians: Lower Gali experienced violence while neighboring Upper Gali did not. The paper argues that state institutions create an incentive for ethnic minorities to collaborate with the state, regardless of minority preferences, and this helps maintain peace. However, preferences become important where institutions are weak and members of the ethnic minority have the opportunity to defect; this increases the likelihood of violence. The results build on the ethnic security dilemma by specifying micro-mechanisms and challenging the theory's reliance on intransigent ethnic identities in explaining the causes of post-partition violence. 相似文献
