The threat posed by the proliferation of weapons of mass destruction is real and urgent. Combating this threat requires a new and comprehensive approach by the federal government. It requires sustained leadership at the top and an organizational structure that can set policies and objectives for combating proliferation; develop integrated, government‐wide plans to implement those policies and objectives, including plans for acquiring necessary technology; make appropriate decisions regarding how resources should be allocated to carry out those plans; and regularly evaluate the effectiveness of our policies, programs, and operations. There is no such comprehensive approach today. 相似文献

This article proposes two dual‐ascent algorithms and uses each in combination with a primal drop heuristic embedded within a branch and bound framework to solve the uncapacitated production assembly distribution system (i.e., supply chain) design problem, which is formulated as a mixed integer program. Computational results indicate that one approach, which combines primal drop and dual‐ascent heuristics, can solve instances within reasonable time and prescribes solutions with gaps between the primal and dual solution values that are less than 0.15%, an efficacy suiting it for actual large‐scale applications. © 2012 Wiley Periodicals, Inc.

The insurgency in southern Thailand has proven to be intractable over the last few years. The insurgents, who comprise several different groups, have largely retained the initiative in a series of relatively unsophisticated operations. Although involving ethnic Malay Muslims – and marked by an increasingly strong Islamist ideology – the insurgency has been predominantly ethnic rather than religious. External jihadist involvement has been minimal at best. The recent coup in Thailand may improve the odds of reaching some form of accommodation with the southern insurgents; but it is likely that the south will remain a continuing security problem for Bangkok. 相似文献

Multiple ethnic insurgencies have existed in Myanmar since independence. The military junta's response has been extremely brutal at the tactical level, but has shown some political astuteness at the strategic level, with a series of ceasefires with most of the ethnic groups. Despite these ceasefires – most of which have resulted in the continued existence of quasi-independent armed groups – other ethnic movements have continued their armed operations. The overall strategic picture is one of stalemate, with the ethnic movements continuing to exist, but with few realistic prospects of expanding their operations. 相似文献

The northeast states of India have faced a series of insurgencies almost since independence. Most insurgent groups have been based on the competing demands of various ethnic groups, with conflicts not only between the insurgents and the government, but also between groups. The combination of anti-government and intercommunal violence shows little sign of ending. Although the Indian government has made progress in dealing with the largest groups, the continued existence of several dozen insurgent movements represents a significant security threat to internal stability in India. 相似文献

Militaries commonly require recruits to pass a test that measures aptitude for military service. In this paper, we show that such tests may also act as a device for screening out low-motivation recruits, even if it is assumed that motivation is not measured by such tests and is not correlated with aptitude. 相似文献

This article examines the problem of optimally selecting from several unknown rewards when there are given alternative, costly sources of information. The optimal rule, indicating the information to be purchased and the reward to be selected, is specified as a function of the decision maker's prior probabilities regarding the value of each alternative. The rule is surprisingly complex, balancing prior beliefs, the “informativeness” of the relevant information system, and the cost of acquiring information. 相似文献

An alternating renewal process starts at time zero and visits states 1,2,…,r, 1,2, …,r 1,2, …,r, … in sucession. The time spent in state i during any cycle has cumulative distribution function Fi, and the sojourn times in each state are mutually independent, positive and nondegenerate random variables. In the fixed time interval [0,T], let Ui(T) denote the total amount of time spent in state i. In this note, a central limit theorem is proved for the random vector (Ui(T), 1 ≤ i ≤ r) (properly normed and centered) as T → ∞. 相似文献
