The Lord's Resistance Army (LRA) has created a pervasive climate of fear in northern Uganda. This study addresses the purpose of this conduct. Diverging from the traditional ‘greed-grievance’ approach to the study of new wars, the LRA's behaviour is analyzed from a strategic perspective. Specifically, the article focuses on the LRA's use of mutilation, abduction, surprise, and unpredictable attacks. The conclusion is that the LRA is strategically using fear as a force multiplier, to further its organizational survival, and as a way to fight a political ‘dirty war’. 相似文献

One of the effects of Deng Xiaoping's economic reforms is the steady erosion of the ideological integrity of Marxism‐Leninism‐Maoism. To compensate for that erosion, the Chinese Communist Party has turned to patriotic nationalism for a new source of legitimacy. China's new nationalism transcends mere rhetoric but is manifested in the behavior of its armed forces ‐ which makes an understanding of the nationalist ideology of the People's Liberation Army (PLA) important. As revealed in PLA and related military publications, that ideology is a potentially problematic mix of wounded pride, historical resentment, and irredentism. 相似文献

History teaches that counterinsurgency and counterterrorism campaigns have never been won through purely military action. Defeating an opponent who avoids open battle, but who uses force to reach his goals, including terrorist action, requires a combination of police, administrative, economic and military measures. As a counterinsurgency campaign should pursue a comprehensive political objective, it requires high levels of civil–military cooperation. However, current NATO doctrine for Civil–Military Cooperation (CIMIC) as it emerged from the 1990s is founded in conventional war-fighting and outdated peacekeeping doctrine. CIMIC's focus is on supporting military objectives rather than enabling the military to make a coherent contribution to political objectives. This makes CIMIC unfit for the Alliance's main operational challenges that have expanded from peace operations on the Balkans to countering insurgent terrorism in Afghanistan. When developing CIMIC, the Alliance obviously neglected the historical lessons from counterinsurgency campaigns. 相似文献

We consider a generalization of the well‐known generalized assignment problem (GAP) over discrete time periods encompassed within a finite planning horizon. The resulting model, MultiGAP, addresses the assignment of tasks to agents within each time period, with the attendant single‐period assignment costs and agent‐capacity constraint requirements, in conjunction with transition costs arising between any two consecutive periods in which a task is reassigned to a different agent. As is the case for its single‐period antecedent, MultiGAP offers a robust tool for modeling a wide range of capacity planning problems occurring within supply chain management. We provide two formulations for MultiGAP and establish that the second (alternative) formulation provides a tighter bound. We define a Lagrangian relaxation‐based heuristic as well as a branch‐and‐bound algorithm for MultiGAP. Computational experience with the heuristic and branch‐and‐bound algorithm on over 2500 test problems is reported. The Lagrangian heuristic consistently generates high‐quality and in many cases near‐optimal solutions. The branch‐and‐bound algorithm is also seen to constitute an effective means for solving to optimality MultiGAP problems of reasonable size. © 2012 Wiley Periodicals, Inc.

Stochastic dynamic programming models are attractive for multireservoir control problems because they allow non‐linear features to be incorporated and changes in hydrological conditions to be modeled as Markov processes. However, with the exception of the simplest cases, these models are computationally intractable because of the high dimension of the state and action spaces involved. This paper proposes a new method of determining an operating policy for a multireservoir control problem that uses stochastic dynamic programming, but is practical for systems with many reservoirs. Decomposition is first used to reduce the problem to a number of independent subproblems. Each subproblem is formulated as a low‐dimensional stochastic dynamic program and solved to determine the operating policy for one of the reservoirs in the system. © 2006 Wiley Periodicals, Inc.
