This article explores why jihadis make propaganda. Through the analytical lens of Bockstette’s 2008 framework for jihadi communication strategies, it assesses two of the Islamic State’s most important doctrinal texts on media jihad—the first, a little-known speech by Abu Hamzah al-Muhajir that was published posthumously in 2010, and the second, a field-guide prepared by the Islamic State’s official publishing house, the Himmah Library, in 2015. After drawing out the core insights, similarities and presuppositions of each text, it discusses the enduring salience of Bockstette’s model on the one hand and these two texts on the other, noting that, while it is imprudent to make policy predictions based on them alone, so too would it be remiss to ignore the strategic insights they contain.

It will have been 25 years since the Rwanda genocide in spring 2019. As more information about the Rwanda genocide becomes available and as the narrative of those events continues to evolve, there is still much to learn from the case study of Rwanda about the role of media in stimulating and responding to mass atrocities. In an era of social media saturation, near-ubiquitous mobile device penetration and dramatic shifts in traditional news media, it is more important than ever to examine the nexus between media and mass atrocity. Advances in information and communications technology have reshaped the media landscape, rendering mass atrocities in distant countries more immediate and harder to ignore. And yet, a cohesive international response to mass atrocities has been elusive. Social media tools can be used to inform and engage, but — in an echo of hate radio in Rwanda — can also be used to demonize opponents and mobilize extremism. With enhanced and relatively inexpensive communications technologies, ordinary citizens around the globe can capture live footage of human rights abuses before journalists have the chance, making social media itself a global actor, affecting the responses of national governments and international organizations to threats against peace and security and human rights. And yet, despite the extended reach that technological advances have afforded traditional news media and social media, the media impact in mass atrocity events is still a complex subject. Specifically, we are left with many troubling questions, still unresolved despite the passage of time since Rwanda. What role do media play in alerting the international community to looming mass atrocity? Could more informed and comprehensive coverage of mass atrocities mitigate or even halt the killing by sparking an international outcry? How do we assess the impact of hate media reporting in a killing spree? What is the role of the media in trying to encourage amelioration of the conflict or post-conflict reconciliation? What do the lessons of Rwanda mean now, in an age of communications so dramatically influenced by social media? Media and Mass Atrocity: The Rwanda Genocide and Beyond grapples with these questions.

Right-wing extremists and Islamist extremists try to recruit new followers by addressing their national (for instance, German) or religious (Muslim) social identity via online propaganda videos. Two studies examined whether capitalizing on a shared group-membership affects the emotional and cognitive response towards extremist propaganda. In both studies, Germans/non-migrants, Muslim migrants and control participants (N = 235) were confronted with right-wing extremist and Islamist extremist videos. Emotional and cognitive effects of students (Study 1) and apprentices (Study 2) were assessed. Results showed a general negative evaluation of extremist videos. More relevant, in-group propaganda led to more emotional costs in both studies. Yet, the responses varied depending on educational level: students reported more negative emotions and cognitions after in-group directed videos, while apprentices reported more positive emotions and cognitions after in-group directed propaganda. Results are discussed considering negative social identities.

The attacks suffered by France in January and November 2015, and then in the course of 2016, especially the Nice attack, provoked intense online activity both during the events and in the months that followed. The digital traces left by this reactivity and reactions to events gave rise, from the very first days and even hours after the attacks, to a ‘real-time’ institutional archiving by the National Library of France (Bibliothèque nationale de France) and the National Audio-visual Institute (Institut national de l’audiovisuel). The results amount to millions of archived tweets and URLs. This article seeks to highlight some of the most significant issues raised by these relatively unprecedented corpora, from collection to exploitation, from online stream of data to its mediation and re-composition. Indeed, web archiving practices in times of emergency and crises are significant, almost emblematic, loci to explore the human and technical agencies, and the complex temporalities, of ‘born-digital’ heritage. The cases examined here emphasize the way these ‘emergency collections’ challenge the perimeters and the very nature of web archives as part of our digital and societal heritage, and the guiding visions of its governance and mission. Finally, the present analysis underlines the need for a careful contextualization of the design process – both of original web pages or tweets and of their archived images – and of the tools deployed to collect, retrieve and analyse them.

Social networks are being used by terrorist organizations to distribute messages with the intention of influencing people and recruiting new members. The research presented in this paper focuses on the analysis of Twitter messages to detect the leaders orchestrating terrorist networks and their followers. A big data architecture is proposed to analyze messages in real time in order to classify users according to diferent parameters like level of activity, the ability to infuence other users, and the contents of their messages. Graphs have been used to analyze how the messages propagate through the network, and this involves a study of the followers based on retweets and general impact on other users. Ten, fuzzy clustering techniques were used to classify users in profiles, with the advantage over other classifcations techniques of providing a probability for each profile instead of a binary categorization. Algorithms were tested using public database from Kaggle and other Twitter extraction techniques. The resulting profiles detected automatically by the system were manually analyzed, and the parameters that describe each profile correspond to the type of information that any expert may expect. Future applications are not limited to detecting terrorist activism. Human resources departments can apply the power of profle identification to automatically classify candidates, security teams can detect undesirable clients in the financial or insurance sectors, and immigration officers can extract additional insights with these
techniques.

We analyze 26.2 million comments published in Arabic language on Twitter, from July 2014 to January 2015, when Islamic State of Iraq and Syria (ISIS)’s strength reached its peak and the group was prominently expanding the territorial area under its control. By doing that, we are able to measure the share of support and aversion toward the Islamic State within the online Arab communities. We then investigate two specific topics. First, by exploiting the time granularity of the tweets, we link the opinions with daily events to understand the main determinants of the changing trend in support toward ISIS. Second, by taking advantage of the geographical locations of tweets, we explore the relationship between online opinions across countries and the number of foreign fighters joining ISIS.
