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.     

CRF与规则相结合的军事命名实体识别研究

作战命令的分词是作战指令自动化生成、文图转换等各种指挥自动化技术的重要基础。在作战指令进行分词处理的过程中,军事命名实体的识别是技术难点之一。命名实体是信息的主要载体,它的识别是军事信息抽取的关键。提出了一种基于CRF模型与规则相结合的命名实体识别方法,结合基本特征与外部词典特征,提高了实体识别效率;在后期进行规则优化,最终实现高效的命名实体识别。实验证明,该方法是行之有效的。能够成功解决命名实体的自动识别问题。

Countering insurgency: Turkey’s policy toward the PKK’s transnational dynamics in Europe

Insurgents often develop international connections and benefit from external assistance from a variety of sources. Support from diaspora communities has long been considered one of the critical external factors in the persistence of insurgent groups. Yet how the counterinsurgent state addresses external support from transnational ethnic communities and what factors influence the state's policies remain understudied. By focusing on the transnational political practices of the Kurdish community and the PKK in Western Europe, this paper examines how Turkey has addressed the diasporic support for the PKK since the 1980s. It shows that three major factors – the composition of foreign policy decision-makers, their ideological contestation over the Kurdish question, and the European political context – have affected Turkey's policy regarding the PKK's transnational dynamics in Europe.     

Youth Between State and Rebel (Dis)Orders: Contesting Legitimacy from Below in Sub-Sahara Africa

Abstract

The Sahel has gained attention in international politics as one of the central theatres in the war on terrorism. International actors in this war seek alliances with states in the region, reinforcing the latter’s military strength and their legitimacy from outside. At the same time, increasingly-connected young populations question the legitimacy of their states, and contest that legitimacy from within and below. In the absence of states delivering any reasonable form of social contract, young people become torn between different governing orders and find themselves in a liminal space. In this article we present the cases of youth in Mali and Chad, who find themselves in a period of re-definition of their position in society and hence search for legitimate structures representation. In this search they may frame their belonging in terms of ethnicity, religion or political opposition – and increasingly also in adherence to global citizenship. New information flows and connectivity among young people in these regions, and between them and the diaspora, has given a new turn to their search for citizenship/belonging and rightful representation. However, whether their search will be successful in this geopolitical context is questionable.
