What Eye Movements and Facial Expressions Tell Us about User-Friendliness: Testing a Tool for Communicators and Journalists
2018 Lindholm J., Backholm K., and Högväg J. Chapter
Technical solutions can be important when key communicators take on the task of making sense of social media flows during crises. However, to provide situation awareness during high-stress assignments, usability problems must be identified and corrected. In usability studies, where researchers investigate the user-friendliness of a product, several types of data gathering methods can be combined. Methods may include subjective (surveys and observations) and psychophysiological (e.g. skin conductance and eye tracking) data collection. This chapter mainly focuses on how the latter type can provide detailed clues about user-friendliness. Results from two studies are summarised. The tool tested is intended to help communicators and journalists with monitoring and handling social media content during times of crises. Book Edited by Harald Hornmoen and Klas Backhoem.
What is Gab? A Bastion of Free Speech or an Alt-Right Echo Chamber?
2018 Zannettou, S., Bradlyn, B., De Cristofaro, E., Kwak, H., Sirivianos, M., Stringhini, G. and Blackburn, J. Article
Over the past few years, a number of new "fringe" communities, like 4chan or certain subreddits, have gained traction on the Web at a rapid pace. However, more often than not, little is known about how they evolve or what kind of activities they attract, despite recent research has shown that they influence how false information reaches mainstream communities. This motivates the need to monitor these communities and analyze their impact on the Web's information ecosystem. In August 2016, a new social network called Gab was created as an alternative to Twitter. It positions itself as putting "people and free speech first'", welcoming users banned or suspended from other social networks. In this paper, we provide, to the best of our knowledge, the first characterization of Gab. We collect and analyze 22M posts produced by 336K users between August 2016 and January 2018, finding that Gab is predominantly used for the dissemination and discussion of news and world events, and that it attracts alt-right users, conspiracy theorists, and other trolls. We also measure the prevalence of hate speech on the platform, finding it to be much higher than Twitter, but lower than 4chan's Politically Incorrect board.
What to Do about the Emerging Threat of Censorship Creep on the Internet
2017 Citron, D.K. Policy
Popular tech companies—Google, Facebook,
Twitter, and others—have strongly protected
free speech online, a policy widely associated
with the legal norms of the United States.
American tech companies, however, operate
globally, and their platforms are subject to regulation
by the European Union, whose member states offer less
protection to expression than does the United States.
European regulators are pressuring tech companies to
control and suppress extreme speech. The regulators’
clear warning is that, if the companies do not comply
“voluntarily,” they will face harsher laws and potential
liability. This regulatory effort runs the risk of censorship
creep, whereby a wide array of protected speech, including
political criticism and newsworthy content, may end up
being removed from online platforms on a global scale.
What’s Love Got To Do With It? Framing ‘JihadJane’ in the US Press
2012 Conway, M. and McInerney, L. Journal
The purpose of this article is to compare and contrast the US press coverage accorded to female terrorist plotter, Colleen LaRose, with that of two male terrorist plotters in order to test whether assertions in the academic literature regarding media treatment of women terrorists stand up to empirical scrutiny. The authors employed TextSTAT software to generate frequency counts of all words contained in 150 newspaper reports on their three subjects and then slotted relevant terms into categories fitting the commonest female terrorist frames, as identified by Nacos’s article in Studies in Conflict and Terrorism (2005). The authors’ findings confirm that women involved in terrorism receive significantly more press coverage and are framed vastly differently in the US press than their male counterparts.
Where are All the Cyber Terrorists? From Waiting for Cyber Attack to Understanding Audiences
2016 Droogan, J. and Waldek, L. Article
This paper presents a review of recent academic scholarship and debates on cyber terrorism, and more broadly of what is known about terrorist's direct use of the Internet as weapon and, less directly, as a communication device. It presents an overview of a field of discourse that has, since its inception, provided a number of foreboding and even doomsday warnings about the future of cyber terrorism, which in the main have failed to come to realization. First, it surveys why these gloomy warnings regarding future proliferation of cyber terrorism have not been born out in practice, and explains that rather than looking for instances of the Internet being used directly as a weapon by terrorists, current debates in academic and policy circles have shifted to trying to measure and ascertain the role that the Internet plays in spreading and supporting extremist discourse to ever wider audiences. It continues by posing a series of questions regarding online audiences that are in need of future research if we are to better understand the role of the Internet in spreading and supporting violent extremist discourse and cultivating terrorism, most importantly the role of audiences as autonomous agents in navigating, reacting and responding to online violent extremist materials.
White Hoods And Keyboards: An Examination Of The Klan And Ku Klux Klan Websites
2011 Selepak, A.G. PhD Thesis
The Ku Klux Klan is the oldest and most well-known extremist group in the United States with a history dating back nearly 150 years. The Klan has been featured in numerous movies, books, documentaries, and been the center of countless news stories. But, in recent years, the Ku Klux Klan has been all but forgotten by researchers who believed the Klan was a dying organization with a nearly extinct membership of individuals who could not accept the end of segregation and the Klan‟s defeat during the Civil Rights Movement. But, recent research by the Southern Poverty Law Center shows the Klan is not extinct, nor is the Klan dying. Instead, the Ku Klux Klan is growing with new members joining across the country and the world. Research has shown the recent growth in membership has been caused by the election of the first black President of the United States, a poor economy and high unemployment, and an increase in the minority population of the United States brought on by immigration. In addition, research has suggested the growth in groups like the Ku Klux Klan has been caused by an increase in the number of Ku Klux Klan web sites on the Internet. This study used grounded theory and a mixed-method approach to examine the proliferation of Klan web sites and to achieve a better understanding of the Ku Klux Klan and its recent rise in membership. Using content analysis of current Klan web sites and in-depth interviews with current Klan leaders, this study examined the beliefs of the Ku Klux Klan, the purpose of the Ku Klux Klan in the 21st Century, why the Klan creates and maintains web sites, and examined the membership of the Ku Klux Klan. Based on analysis of Klan web sites and interviews with Klan leaders, Ku Klux Klan beliefs fall under two general themes. First, the Klan believes white Christians are held to a double standard and not allowed to have pride in their culture and heritage, while at the same time treated unfairly by the media, society, and the government. Second, the Klan believes in racial separation, and the need for whites to either remove themselves from a society perceived as against them or to combat that society through political and legal involvement. Results suggest the Klan creates web sites not for the sole purpose of recruit, but instead, to inform the general public of the Klan‟s goals to combat a double standard in society, and to market the Klan to greater segment of the American population, by using the Internet to rebrand the image of the Klan as an organization dedicated to preserving white, American, and Christian culture. In addition, results indicate no one group exists that can claim the title of “Ku Klux Klan.” Instead, this study found a variety of Klan organizations exist with competing ideologies and beliefs. Using a mixed-methods approach of incorporating quantitative and qualitative data, this study found two types of Klan organizations exist. One Klan is a traditional fraternal organization, while the other is a more radical and extremist organization intent on becoming a paramilitary organization, church or political party. Members of the Klan were generally observed to be average American citizens with families. More specifically, Klan members were revealed to be white, politically and religiously conservative Christians, many of whom were military veterans and owned their own business, and in general were opposed to a changing world and changing American society.
White Supremacist Networks on the Internet
2000 Burris, V., Smith, E. and Strahm, A. Journal
In this paper we use methods of social network analysis to examine the inter-organizational structure of the white supremacist movement. Treating links between Internet websites as ties of affinity, communication, or potential coordination, we investigate the structural properties of connections among white supremacist groups. White supremacism appears to be a relatively decentralized movement with multiple centers of influence, but without sharp cleavages between factions. Interorganizational links are stronger among groups with a special interest in mutual affirmation of their intellectual legitimacy (Holocaust revisionists) or cultural identity (racist skinheads) and weaker among groups that compete for members (political parties) or customers (commercial enterprises). The network is relatively isolated from both mainstream conservatives and other extremist groups. Christian Identity theology appears ineffective as a unifying creed of the movement, while Nazi sympathies are pervasive. Recruitment is facilitated by links between youth and adult organizations and by the propaganda efforts of more covertly racist groups. Links connect groups in many countries, suggesting the potential of the Internet to facilitate a whitesupremacist “cyber-community” that transcends regional and national boundaries.
White Supremacists, Oppositional Culture and the World Wide Web
2005 Adams, J. and Roscigno, V.J. Journal
Over the previous decade, white supremacist organizations have tapped into the ever emerging possibilities offered by the World Wide Web. Drawing from prior sociological work that has examined this medium and its uses by white supremacist organizations, this article advances the understanding of recruitment, identity and action by providing a synthesis of interpretive and more systematic analyses of thematic content, structure and associations within white supremacist discourse. Analyses, which rely on TextAnalyst, highlight semantic networks of thematic content from principal white supremacist websites, and delineate patterns and thematic associations relative to the three requisites of social movement culture denoted in recent research - namely identity, interpretational framing of cause and effect, and political efficacy. Our results suggest that nationalism, religion and definitions of responsible citizenship are interwoven with race to create a sense of collective identity for these groups, their members and potential recruits. Moreover, interpretative frameworks that simultaneously identify threatening social issues and provide corresponding recommendations for social action are employed. Importantly, and relative to prior work, results how how the interpretation of problems, their alleged causes and the call to action are systematically linked. We conclude by discussing the framing of white supremacy issues, the organizations' potential for recruitment, and how a relatively new communication medium, the Internet, has been cheaply and efficiently integrated into the white supremacist repertoire. Broader implications for social movement theory are also explored.
Who Are the Online Extremists Among Us? Sociodemographic Characteristics, Social Networking, and Online Experiences of Those Who Produce Online Hate Materials
2018 Costello, M. and Hawdon, J. Journal
What are the factors associated with the production of online hate material? Past research has focused on attributes associated with seeing and being targeted by online hate material, but we know surprisingly little about the creators of such material. This study seeks to address this gap in the knowledge, using a random sample of Americans, aged 15–36. Descriptive results indicate that nearly one-fifth of our sample reported producing online material that others would likely interpret as hateful or degrading. We utilize a logistic regression to understand more about these individuals. Results indicate that men are significantly more likely than women to produce online hate material. This fits with the broader pattern of men being more apt to engage in deviant and criminal behaviors, both online and offline. Other results show that the use of particular social networking sites, such as Reddit, Tumblr, and general messaging boards, is positively related to the dissemination of hate material online. Counter to expectations, the use of first-person shooter games actually decreased the likelihood of producing hate material online. This could suggest that violent videogames serve as outlet for aggression, and not a precursor. In addition, we find that individuals who are close to an online community, or spend more time in areas populated by hate, are more inclined to produce hate material. We expected that spending more time online would correlate with the production of hate, but this turned out not to be true. In fact, spending more time online actually reduces the likelihood of doing so. This result could indicate that individuals who spend more time online are focused on a particular set of tasks, as opposed to using the Internet to disseminate hate.
Who Dissemnates Rumiyah? Examining the Relative Influence of Sympathiser and Non-Sympathiser Twitter Users
2018 Grinnell D., Macdonald S., Mair D. & Lorenzo-Dus N. Report
This paper was presented at the 2nd European Counter Terrorism Centre (ECTC) Advisory Group conference, 17-18 April 2018, at Europol Headquarters, The Hague. The views expressed are the authors’ own and do not necessarily represent those of Europol.
In a speech delivered at the United Nations General Assembly in September 2017, the U.K. Prime Minister Theresa May called on social media companies to do more to remove and block terrorist content from their platforms [1]. In the speech she stated that the average lifespan of online propaganda from the so-called Islamic State (IS) was 36 hours. For such content to be disrupted effectively, she claimed that this figure needed to be reduced to one to two hours. This has since come to be known as the ‘golden window’: if terrorist material can be detected and removed within one to two hours, its spread will be prevented.
Who Matters Online: Measuring influence, evaluating content and countering violent extremism in online social networks
2013 Berger, J.M. and Strathearn, B. Report
It is relatively easy to identify tens of thousands of social media users who have an interest in violent ideologies, but very difficult to figure out which users are worth watching. For students of extremist movements and those working to counter violent extremism online, deciphering the signal amid the noise can prove incredibly daunting. This paper sets out a first step in solving that problem. The authors have devised a scoring system to find out which social media accounts within a specific extremist circle were most influential and most prone to be influenced (a tendency we called exposure).
Who Views Online Extremism? Individual Attributes Leading to Exposure
2016 Costello, M., Howdon, J. and Ratliff, T. Journal
Who is likely to view materials online maligning groups based on race, nationality, ethnicity, sexual orientation, gender, political views, immigration status, or religion? We use an online survey (N = 1034) of youth and young adults recruited from a demographically balanced sample of Americans to address this question. By studying demographic characteristics and online habits of individuals who are exposed to online extremist groups and their messaging, this study serves as a precursor to a larger research endeavor examining the online contexts of extremism.

Descriptive results indicate that a sizable majority of respondents were exposed to negative materials online. The materials were most commonly used to stereotype groups. Nearly half of negative material centered on race or ethnicity, and respondents were likely to encounter such material on social media sites. Regression results demonstrate African-Americans and foreign-born respondents were significantly less likely to be exposed to negative material online, as are younger respondents. Additionally, individuals expressing greater levels of trust in the federal government report significantly less exposure to such materials. Higher levels of education result in increased exposure to negative materials, as does a proclivity towards risk-taking.

Why the Internet is Not Increasing Terrorism
2014 Benson, D.C. Journal
Policymakers and scholars fear that the Internet has increased the ability of transnational terrorists, like al Qaeda, to attack targets in the West, even in the face of increased policing and military efforts. Although access to the Internet has increased across the globe, there has been no corresponding increase in completed transnational terrorist attacks. This analysis examines the causal logics—which have led to the conventional wisdom—and demonstrates both theoretically and empirically that the Internet is not a force multiplier for transnational terrorist organizations. Far from being at a disadvantage on the Internet, state security organs actually gain at least as much utility from the Internet as terrorist groups do, meaning that at worst the Internet leaves the state in the same position vis-a`-vis terrorist campaigns as it was prior to the Internet.
Winning the Cyberwar Against ISIS
2017 Byers, A., and Mooney, T. Article
Despite the efforts of the United States and its allies to fight the Islamic State (also known as ISIS), the group remains a formidable danger. It holds territory in Afghanistan, Iraq, Libya, Nigeria, and Syria and directs cells in Bangladesh, Egypt, France, the North Caucasus, and Yemen. ISIS operatives have conducted terrorist attacks in Europe—including one in November 2015 in Paris that killed 130 people—and lone wolves inspired by its propaganda have committed violence throughout the West.

The administration of U.S. President Donald Trump, like that of former President Barack Obama, has publicly committed itself to defeating ISIS using conventional military means. This approach has its benefits, but it ignores a significant part of the threat posed by ISIS. The group is strong not only on the battlefield but also in cyberspace, where it uses sophisticated techniques to communicate with sympathizers, spread propaganda, and recruit new members all around the world. As one ISIS defector told The Washington Post in 2015, “The media people are more important than the soldiers.”
Women and Violent Radicalization
2016 Conseil du statut de la femme and Centre for the Prevention of Radicalization Leading to Violence Report
As myths, stereotypes and media representations circulate about the several hundred Western women who have gone to Syria and joined the jihadists, it seems to us essential to try to understand the motives and explanatory factors behind the radicalization of these girls and women. What mechanisms and processes lead them to become radicalized and to join such groups?
Who are these women who radicalize to the point of risking their safety and well-being? Above all, how shall we understand the gender dimensions of the current phenomena of violent radicalization?

Until now, documentation of the radicalization of girls and women in Québec, with a gender-differentiated perspective, has been non-existent. We therefore decided that it was essential to do more than offer a summary document, by exploring empirically, across Québec, the radicalization of women who have joined, or tried to join, jihadist groups in Syria and Iraq.
Women's Connectivity in Extreme Networks
2016 Manritque, P., Cao, Z., Gabriel, A., Horgan, J., Gill, P., Qi, H., Restrepo, E.M., Johnson, D., Wuchty, S., Song, C. and Johnson, N. Article
A popular stereotype is that women will play more minor roles than men as environments become more dangerous and aggressive. Our analysis of new longitudinal data sets from offline and online operational networks [for example, ISIS (Islamic State)] shows that although men dominate numerically, women emerge with superior network connectivity that can benefit the underlying system’s robustness and survival. Our observations suggest new female-centric approaches that could be used to affect such networks. They also raise questions about how individual contributions in high-pressure systems are evaluated.
Women, Social Media and Violent Extremism
2015 Chaudry, R. Video
As a growing number of women engage in violent extremism, urgent questions about their recruitment and motivations are yet to be answered, particularly on the role of social media. Extremist organizations such as the Islamic State are adept at using social media messages to attract Western followers. Less clear is what tools can be used to deter recruitment when female extremists are taking a bigger part in orchestrating these campaigns. Join the Conflict Prevention and Resolution Forum at the U.S. Institute of Peace on May 10 for a discussion of women, social media and extremism.

In the view of many analysts, coercion is the reason most women join violent extremist groups, insurgencies and revolutionary organizations. There are, however, more sophisticated, nuanced and complex explanations such as a search for identity and sense of belonging. At the forum, a panel of experts will consider these motives and the means to address them online in the context of countering violent extremism. Join the conversation on Twitter with #CPRF.
Worldwide Online Jihad versus the Gaming Industry Reloaded – Ventures of the Web
2010 Prucha, N. Chapter
[Chapter in, "New Approaches to the Analysis of Jihadism: On and Offline", Rüdiger Lohlker (ed.)] Jihadism has been an important issue of public discussions since 9/11. Internet media have been used by Jihadis as means of communication, propaganda, recruitment, and even training purposes. In this volume, the processes of interaction on Jihadi internet sites are analysed. Particular attention lays on the mechanisms of spread of propaganda via the internet by diverse technical means. The process of transformation of Islamic knowledge into Jihadi knowledge, the rhetorics of videos, the development of South Asian Jihadi organisations and some conceptual issues are discussed.
Writing On The Walls: Discourses On Bolivian Immigrants In Chilean Meme Humor
2019 Haynes, N. Article
Internet memes have become a popular form through which northern Chileans express frustrations with their marginalization on global, national, and local levels. At the same time, many of these memes criticize Bolivian immigrants for using resources and taking jobs from “true Chileans.” The humorous nature of these texts mitigates the extremity of embedded racial and nationalist ideologies, which are more explicitly expressed in political speech, news media, and quotidian language. This article uses critical discourse analysis to trace ideological formations across multiple online and offline instantiations, making visible a continuum of extreme speech. Through these connections, we see how anti-immigrant discourses position northern residents in a formation of nested marginality. Memes are thus a central way that disenfranchised Chilean citizens reinforce a worldview in which they consider themselves deserving of greater access to resources than Bolivians, precisely because of their marginalized position in relation to the nation.
