Cyberspace is a new domain of operation, with its own characteristics. Cyber weapons differ qualitatively from kinetic ones: They generate effects by non-kinetic means through information, technology, and networks. Their properties, opportunities, and constraints are comparable to the qualitative difference between conventional and nuclear weapons. New weapons and their target sets in a new domain raise a series of unresolved policy challenges at the domestic, bilateral, and international levels about deterrence, attribution, and response. They also introduce new risks: uncertainty about unintended consequences, expectations of efficacy, and uncertainty about both the target’s and the international community’s response. Cyber operations offer considerable benefits for states to achieve strategic objectives both covertly and overtly. However, without a strategic framework to contain and possibly deter their use, make state and non-state behavior more predictable in the absence of reciprocal norms, and limit their impact, an environment where states face persistent attacks that nonetheless fall below the threshold of armed conflict presents a policy dilemma that reinforces collective insecurity. 相似文献

Between 2014 and 2017, no less than 10 different non-governmental organizations (NGOs) conducted maritime Search and Rescue (SAR) operations off the coast of Libya. By rescuing over 100,000 migrants in three years, these NGOs became the largest provider of SAR in the Mediterranean. The theory of institutionalism suggests that organizations conducting similar activities are likely to converge in a process of mimetic isomorphism, deliberately imitating one another to increase their effectiveness and cope with uncertainty. These 10 SAR NGOs, however, developed two different rescue models: While some rescued migrants and disembarked them in Italian ports, others only simply assisted those in distress until the arrival of another ship transporting them to land. They also cooperated with Italian and European authorities to different degrees. Why did SAR NGOs imitated many elements of existing non-governmental rescue models, but discarded some others? This article argues that differences in material capabilities and organizational role conceptions are crucial to explain why newer SAR NGOs have imitated most but not all of their predecessors’ policies, engaging in a process of “selective emulation.” 相似文献

Local perceptions of the EU’s role in peacebuilding: The case of security sector reform in Palestine
ABSTRACTPerception research can make a valuable contribution to the study of the local dimension in EU peacebuilding. The conceptual framework developed in this article distinguishes between perceptions of the “legitimacy,” “effectiveness,” and “credibility” of EU peacebuilding practices, which are crucial factors for successful peacebuilding. Relying on the case of the EU’s support for security sector reform (SSR) in Palestine, this article shows that local stakeholders—which participate in various EU-sponsored training and capacity-building programs—display considerable support for liberal peacebuilding norms. Yet, perceived discrepancies between the EU’s peacebuilding rhetoric and its SSR activities have severely undermined the potential of the EU’s liberal peacebuilding model in the eyes of Palestinian stakeholders. Critical local perceptions are frequently articulated with reference to the EU’s own liberal peacebuilding discourse, pointing to a lack of inclusiveness of the SSR process and deficits in terms of democratic governance and the rule of law. 相似文献

海军舰载导弹防空系统信息作战方法 总被引:1,自引:1,他引:0
信息与火力是海军舰载导弹防空系统研究的核心问题,运用信息作战原理,在给定攻击战机的条件下,对舰载导弹防空系统的信息与火力联合作战能力的分析表明:与提高作战安全性的隐形战机相比,军事诱骗战术更易降低舰载导弹防空系统的火力防御能力.火力对作战能力的贡献约为信息的4倍.根据这一结论,可以为海军舰载导弹防空系统开发出基于信息作战原理的新战法,全面提高指战员在实战中把握信息与火力的运用规律、实施信息作战、做出科学决策和夺取战场胜利的能力. 相似文献

Despite the burgeoning literature on Russia’s renewed power politics, little attention has been paid to the fact that US reactions towards Russia’s military interventions were all but coherent. The USA has chosen weak measures in Georgia in 2008 (shaming) compared to its assertive response in Ukraine in 2014 (sanctions, hard deterrence). This article assesses the explanatory power of neorealist, liberal and constructivist theories for the variation in US reactions towards Russian interventions in Georgia and Ukraine. Our argument is that the constructivist perspective explains the cases best as it highlights the power and communality of normative assessments. The Ukraine crisis was perceived by the USA as a violation of core international norms, especially the non-use of force and the principle of territorial integrity. Relevant international norm carriers shared this assessment of the conflict. In contrast, the perception of the Georgian war centred on the issue of democracy promotion. While democracy is an important aim of US foreign policy, it does not summon the same normative importance as general principles of international law. Furthermore, the perception of the Georgian war remained contested among Western allies, which decreased the communality of the normative assessment. 相似文献

This article traces the evolution of the EU strategic reflection which culminated in the publication of the EU Global Strategy (EUGS) in June 2016. It explains the choices made by EU High Representative Federica Mogherini over this time period—including both the initial strategic assessment and the final EUGS. It provides a behind the scenes view on the players, the organization and the methods of work used to produce a strategic vision for the EU’s role in the world. 相似文献

人民战争思想是战争年代我军战胜日本帝国主义和国民党反动派的强大思想武器,和平建设时期的警卫工作同样需要运用人民战争思想营造良好的警卫环境,为完成繁重的警卫任务创造条件。因此,在全社会构建大警卫格局具有极其重要的意义。 相似文献

警卫任务的特点决定了警卫人员始终处于高度的应激状态下,相同的刺激引起的心理应激是不同的,既可引起焦虑恐惧、精神抑郁、疲倦乏力等消极的反应,也可激发出斗志昂扬、精力充沛、勇敢果断等积极的反应。这主要取决于心理承受能力的强弱。研究应激心理对警卫人员处置突发事件中的影响,对有针对性地开展心理调控和组织处突训练,提高警卫人员心理素质,使其做到临危不惧、处变不惊,从而有效处置各类突发事件,确保警卫对象在任何条件下的安全,具有十分重要的现实意义。 相似文献
