In spite of reform: NATO HQ still in the grips of nations

Security Intergovernmental Organizations, here illustrated by NATO, persist in a “permitted interval” of internationalization, i.e. permitted by its member-states. On the one hand, they are seldom or never permitted to vanish due to member-states' vested interests in retaining them as tools of statecraft, even if their original purposes have become redundant. On the other hand, there is an internationalization ceiling that they must respect: they should not become too autonomous and thereby no longer be suitable as member-state tools. In spite of post-Cold War reform, interviews carried out at NATO Headquarters (HQ) in the late 1980s compared to interviews in 2012 display that a continuous pulling and hauling of forces of internationalization and renationalization have taken place around NATO HQ. The only instance of clear internationalization can be observed in the proactive diplomacy of Secretary General Fogh Rasmussen. There is stiff opposition to the internationalization of abolishing the Military Committee/International Military Staff among minor and South European states, and there is no waning in states' attempts to micro-manage the International Staff. Only external shocks can overcome resistance to internationalizing reform.     

带运力限制及单边时变约束下多出发机场航空战略投送兵力分配模型研究

利用民航力量由多个机场向一个目标机场实施航空战略投送时,由于各民航机场都具有运力限制约束,不可能无限制地快速投送兵力,因此,考虑了在多个出发机场存在运力限制约束的情况下,构建了"投送时间最短,动员机场最少"多目标决策模型,并给出了优化算法和算例.     

Civil society and peacebuilding during Zimbabwe's government of national unity, 2009–2013

This paper employs functionalist, transformative and peacebuilding approaches to explore the role played by civil society in peacebuilding during Zimbabwe's coalition government (2009–2013), under the Church and Civil Society Forum (CCSF). Through the functions of democratisation, socialisation and the rebuilding of communities, the various bottom-up peacebuilding initiatives under the CCSF framework rebuilt broken relationships, provided spaces of encounter between victims and perpetrators, and bridged the paradoxical values of mercy, justice, truth and peace in a context of deep political polarisation. Although the various peacebuilding activities were scattered and sporadic, they do provide a basis for nationwide replication under a ZANU-PF dominated government. The new 2013 constitution provides institutional opportunities for the formulation of a broader national framework for peacebuilding that synergises these efforts by civil society and a politically willing state.     

Born violent: Armed political parties and non-state governance in Lebanon's civil war

We know little of the internal governing practices of non-state actors once in control of territory. Some territories have witnessed the establishment of new institutions of public goods remarkably similar to state institutions. This article compares four armed political parties governing territory during the Lebanese civil war. These non-state violent actors established complex political and economic institutions and administrative structures. Despite the wide range of ideologies and identities of these actors, they all converged in their institutional priorities, although not in their capacities or the particular ways of achieving those priorities. Data from interviews and the actions of the armed political parties suggest a combination of ideology and desire for control is causal in generating public institutions, partly attributable to the high degree of citizen activism marking the Lebanese case.

Modeling and analyzing multiple station baggage screening security system performance

In the aftermath of the tragic events of 11 September 2001, numerous changes have been made to aviation security policy and operations throughout the nation's airports. The allocation and utilization of checked baggage screening devices is a critical component in aviation security systems. This paper formulates problems that model multiple sets of flights originating from multiple stations (e.g., airports, terminals), where the objective is to optimize a baggage screening performance measure subject to a finite amount of resources. These measures include uncovered flight segments (UFS) and uncovered passenger segments (UPS). Three types of multiple station security problems are identified and their computational complexity is established. The problems are illustrated on two examples that use data extracted from the Official Airline Guide. The examples indicate that the problems can provide widely varying solutions based on the type of performance measure used and the restrictions imposed by the security device allocations. Moreover, the examples suggest that the allocations based on the UFS measure also provide reasonable solutions with respect to the UPS measure; however, the reverse may not be the case. This suggests that the UFS measure may provide more robust screening device allocations. © 2004 Wiley Periodicals, Inc. Naval Research Logistics, 2005.
