ABSTRACT In the contemporary multicentric world, sovereign states have to manage carefully the construction of their image, defining their role and aspirations. With the re-definition of the state centric politics, stories become relevant: communication is a form of power, and networked forms of communication are becoming progressively a way to conquer the transnational public spheres. Through strategic narratives of foreign politics, states try to set up the ‘tales’ of international affairs and foreign strategies, to suggest a world vision, a causal interpretation, determining frames that affect transnational actors’ position in the international environment. Sovereign states develop these kind of frame using tools and theories referred to the commercial branding tradition to promote and support their own policies and identity. We decided to investigate how that process is made through information diffusion on digital platforms. In this work, it has been analyzed the content presented through Twitter posts by the Foreign Ministries accounts of four different States dissimilar for geopolitical positioning and security concerns (USA; Israel; France; Sweden), for a period of three months (9/1/2015-11/30/2015); leading to the identification of different models and characteristic patterns of self-representation. The thematic content analysis, based on the identification of macrocategories and micro-issues, has led to the identification of different models and characteristic patterns of self-representation, determined by domestic vicissitudes, and has shown some regularities, caused by the branding vocation of autobiographical online contents.

安全品牌和数字叙述。Twitter 上的安全问题代表

摘要 在当代多中心世界中，主权国家必须谨慎管理其形象的构建，定义其角色和愿望。随着以国家为中心的政治的重新定义，故事变得相关：传播是一种权力形式，网络传播形式正逐渐成为征服跨国公共领域的一种方式。通过对外政治的战略叙事，国家试图建立国际事务和对外战略的“故事”，提出世界视野、因果解释、确定影响跨国行为者在国际环境中地位的框架。主权国家使用参考商业品牌传统的工具和理论来发展这种框架，以促进和支持自己的政策和身份。我们决定研究如何通过数字平台上的信息传播来完成这一过程。在这项工作中，分析了四个不同国家（美国；以色列；法国；瑞典）的外交部帐户通过 Twitter 帖子提供的内容，为期三个月（9/1 /2015-11/30/2015)；导致识别不同的模型和自我表征的特征模式。基于大类和微观问题识别的主题内容分析，导致识别出由国内变迁所决定的不同自我表现模式和特征模式，并显示出一些规律性，这是由自传的品牌使命造成的。在线内容。
