基于EATI的多分辨率联邦可组合性判定研究

联邦可组合性判定是在组建联邦之前,在语义层面分析邦员之间是否存在一种或多种交互方式能够满足联邦的仿真需求和目的。多分辨率联邦执行的有效性是判定联邦可组合性的主要标准。基于EATI方法,提出了多分辨率组合性的形式化理论,给出多分辨率联邦概念模型与多分辨率联邦组合模型的形式化描述。通过比较这两个模型得出联邦有效性的形式化定义,并在此基础上得到联邦可组合性判定方法。该判定方法从实践中总结并在实践中验证,对于构建军用仿真联邦的可行性分析具有一定的借鉴价值。     

Exploring the subsidiarity principle in policing and the operations of the Nigeria Police Force

The provisions of the 1999 Constitution, which recognises the existence of a single police force and forbids parallel police organisations, have oftentimes generated controversies among actors in the Nigerian federal polity. Rising insecurity precipitates lingering questions on the utility and adequacy of a single, highly centralised and centrally controlled police force given Nigeria’s geographic vastness and demographic diversity. Conversely, arguments have also dwelt on the dangers of fragmentation considering Nigeria’s psychosocial, economic and political nature. This article attempts to balance these arguments by analysing policing and the operations of the Nigeria Police Force (NPF) through the lens of the subsidiarity principle. Subsidiarity is a governance principle in federations, captured in the founding documents of the European Union (EU), which prescribes that governmental powers, authorities and duties should be held by the tier that can best perform them equitably, efficiently, effectively, suitably and based on interest and need. Drawing largely on interviews with purposively selected police scholars, political actors, civil society organisations and police personnel, the paper contends that this principle offers a pragmatic solution to the perennial problems of intergovernmental frictions on the use of the police within the context of governance in the Nigerian federation.     

Political opposition,external threats,and elite responses: analyzing domestic security policy in post-Rose Revolution Georgia

In the years since the 2003 Rose Revolution, the popularly elected leadership of the Republic of Georgia has responded to organized protests with a variety of repressive tactics. These reactions suggest that former challengers to authoritarian elites may utilize similar methods of retaining power during crisis periods. Yet, the alleged involvement of agencies of the Russian Federation in fomenting domestic instability has also occupied a central position in the national security policies of the outgoing Saakashvili government. These conditions both preceded and were reinforced by the South Ossetia War of August 2008. This article proposes a theoretical model that represents the intervening effect of interstate conflicts on state–society relations in Georgia from 2003 to present. It presents several hypotheses and possible indicators, data sources, and techniques for analyzing the interaction between characteristics of opposition groups, external threats, and the domestic security practices of contemporary Georgian political elites.

Tanzanian scepticism of a militarised East African Federation and underlying military concerns

Attitudes towards a regional military force are of paramount importance when exploring public support for regional integration. Until now, however, scholarly research has not considered the influence of attitudes towards a regional military mechanism in the sub-Saharan African context. Using Afrobarometer data, we demonstrate that military concerns are vital when exploring Tanzanian attitudes towards the proposed political federation of the East African Community (EAC), the East African Federation (EAF). More specifically, opposition to military cooperation strongly influences Tanzanian scepticism of the EAF. This finding is highly relevant given that referendums in the participating member states must be passed to facilitate political integration. Heightened opposition towards military cooperation raises the possibility of the public rejecting a politically integrated EAC. This poses a potential obstacle to the implementation of joint security policies and crucial mechanisms to provide a more stable region at large. We account for alternative explanations of Tanzanian opinion formation and reflect on the strength of military-orientated concerns for investigating public support for the East African project specifically and regional integration in sub-Saharan Africa more widely.
