Scholars have increasingly sought commonalities among Islamist radical groups, such as ISIS and Boko Haram, despite their ideological differences. The purpose of this qualitative study is to conduct a comprehensive analysis of both ISIS and Boko Haram’s digital campaigns to identify similarities and differences in the content of their digital messaging. Adopting reflexive thematic analysis to explore and interpret dataset which eventually allows to uncover patterns, themes, and meanings within the data, this study, utilized the “propaganda by deed” theory to examines and analyse 20 ISIS Arabic Twitter campaigns and 20 Boko Haram video messages. Data was collected and employed to NVivo software for coding and analysis. The analysis reveals four prominent themes for each group: ISIS emphasizes recruitment, direct calls to jihad, religious discourse, and commemoration of deceased members to attract or mobilize followers. In contrast, Boko Haram’s themes include ideological declarations, religious narratives, affiliations with other groups, and recruitment with calls to jihad. These findings provide a nuanced understanding of both groups, with improved quality for digital campaign in the side of Boko Haram as a result of its allegiance with ISIS, informing more effective and appropriate countermeasures against them and further prevent possible future direct relationship between the two groups.

This paper investigates the link between social media and hate crime. We show that antirefugee sentiment on Facebook predicts crimes against refugees in otherwise similar municipalities with higher social media usage. To establish causality, we exploit exogenous variation in the timing of major Facebook and internet outages. Consistent with a role for “echo chambers,” we find that right-wing social media posts contain narrower and more loaded content than news reports. Our results suggest that social media can act as a propagation mechanism for violent crimes by enabling the spread of extreme viewpoints.

This paper investigates the link between social media and hate crime using hand-collected data from Facebook and Twitter. We study the case of Germany, where the recently emerged right-wing party Alternative für Deutschland (AfD) has developed a major social media presence. Using a difference-in-differences design, we show that right-wing anti-refugee sentiment on Facebook predicts violent crimes against refugees in otherwise similar municipalities with higher social media usage. Consistent with social media being the driving force, the effect decreases with internet outages; increases with user network interactions; is not driven by the news cycle; and does not hold for posts unrelated to refugees. We find similar evidence for the United States, where President Trump’s twitter activity strongly predicts hate crimes against the minorities targeted in his tweets, but not other minorities. We find no effect for the period before Trump’s presidential campaign or measures of general anti-minority sentiment.

The present paper represents an exploratory, dynamic and qualitative application of Social Network Analysis (SNA) for modelling the development of Islamist terror cells in the West. Two well‐known case studies are systematically re‐examined using this methodology as a supporting framework for interpreting the sequence of group development from a social psychological perspective. By drawing attention to salient features of evolving network structures, insight is gained into group functioning and underlying social–psychological mechanisms of radicalisation. This article represents a starting point for giving greater methodological and theoretical recognition to the dynamic structural properties of Islamist terrorist groups in the West. It is intended to stimulate discussion and ideas for future, more rigorous research.

This thesis explores the nature of cyber security at the beginning of the 21st century. In the current security paradigm, security strategies based on anticipatory governance have become essential in the management of the constantly changing cyber security environment. Thus, this thesis aims to understand security strategies and governance introduced in the European region. The increased dependency on cyber space is visible in all public private sectors and governmental operations, as well as communications between groups and individuals. As a result, cyber attacks on public and private entities are increasing. This requires a security framework that is flexible and establishes different types of security cooperation to manage the widespread cyber risks. This is essential to the development of security strategies, governance forms, practices, and guidelines for enhancing resilience and preparedness towards cyber risks. Therefore, I am examining cyber security through the lenses of nodal governance and governmentality, which enables me to understand European cyber security strategies and governance forms developed by the Council of Europe, the European Union, and the North Atlantic Treaty Organization. To analyse existing strategies and governance forms, I have used two critical security schools, the Copenhagen School and the Paris School, which cover different aspects of the security agenda. The thesis develops a substantive analytical framework through two case studies, namely cyber security and cyber terrorism. The findings in this thesis identifies problem areas, such as the complexity of the nodal system, the legislative lacuna, reliance on different governance forms, transparency and accountability, and types of anticipatory governance and regulatory practices.
