Through a descriptive and qualitative content analysis of Al-Qaeda videos from 2001 to 2010, this thesis describes how the organization‘s video production has undergone a surge in production quality by using modern technology and skilled recruits. This thesis also provides background on the Islamic culture and the history of Al-Qaeda in order to put into perspective the goals of the organization‘s framed messages that are incorporated into their videos. The study also draws on the parallels of propaganda used throughout history to highlight how regimes from all over the world understand the importance of communication during a time of war.

This thesis examines extremist Muslim narratives, discourse, and ideologies over the internet by using content analysis to thematically delineate and reconstruct them for the purpose of discovering the argumentation mechanisms through which they become persuasive and appealing. The research problem is that dominant theories in social sciences and popular literature create ‘taken for granted’ inferences that relegate extremist ideologies and narratives to the realm of structural contingencies, psychological pathologies, emotive appeal, manipulated religious ideologies, peculiar and unique rationalities or group dynamics. This thesis hypothesizes instead of the existence of a `logical structure` in extremist Muslim narratives. This logical structure is predicated on rationally persuasive arguments (which employ epistemic and instrumental rationality coupled with inductive/deductive reasoning) that appeal to any rational individual but are ultimately leveraged on for morally wrong end-state choices. Unfortunately much of the counter-narratives today seldom address this logical structure and choose to address the more traditional explanations cited above. Themes and argumentation mechanisms stemming from an examination of extremist Muslim narratives in this study demonstrate the presence and workings of this logical structure.

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.

Recent years have seen a great deal of interest in phenomena such as Al Qaida ‘terrorism’, Islamic ‘radicalism’ or, increasingly, ‘jihadism’ – on the Internet. However, as I argue in this thesis, much work in these areas has been problematic for a number of reasons. Much literature has been narrowly focused on the security issues which it pre-judges the content to raise, and has therefore taken some aspects too literally while ignoring others. Conversely, where authors have addressed ‘jihadi’ content or ‘electronic jihad’ as a phenomenon unto itself, they have had difficulty making sense of it within religious studies or political communication frameworks. In this dissertation, I propose an alternative approach. Deliberately eschewing frameworks based on pre-existing conceptions of religion or politics, I draw, instead, on the academic literature on fandom and subcultural media consumption. Using this conceptual lens, I attempt to analyse jihadism on the Internet (which I define in terms of online consumption of, and identification with self-described ‘jihadi’ content) as a subcultural phenomenon on its own terms. I argue that, without necessarily denying the role that beliefs and ideals expressed in ‘jihadi’ content may sometimes have in sustaining the physical violence of the ‘global jihad’, the cultural practices which constitute Internet jihadism have a tactical logic of their own which may not always coincide with the ‘strategic’ interests of ‘global jihad’. By better understanding what ‘ordinary’ jihadis, most of whom will never participate in violence, get out of their practices, and how they negotiate the apparent contradictions of their situation, I suggest that we may be better placed to understand not only why some jihadis ‘fail’ to negotiate these contradictions, but also, perhaps, to raise questions about how popular media consumption works more generally.

This paper examines the ranking of critical assets within an electrical grid under threat of cyber attack. Critical to this analysis is the assumption of zero hour exploits namely, the threat of an immediate attack as soon as a vulnerability is discovered. Modeling shows that over time load fluctuations as well as other system variations will change the importance of each asset in the delivery of bulk power. As opposed to classic stability studies where risk can be shown to be greatest during high load periods, the zero hour exploit-cyber-risk assumes that vulnerabilities will be attacked as soon as they are discovered. The probability of attacks is made uniform over time to include any and all possible attacks. Examining the impact of an attack and how the grid reacts immediately following an attack will identify and determine the criticality of each asset. This work endeavors to fulfill the NERC Critical Infrastructure Protection Requirements CIP-001-1 through CIP-009-2, cyber security requirements for the reliable supply of bulk power to customers throughout North America.

We present two studies of online ephemerality and anonymity based on the popular discussion board /b/ at 4chan.org: a website with over 7 million users that plays an influential role in Internet culture. Although researchers and practitioners often assume that user identity and data permanence are central tools in the design of online communities, we explore how /b/ succeeds despite being almost entirely anonymous and extremely ephemeral. We begin by describing /b/ and performing a content analysis that suggests the community is dominated by playful exchanges of images and links. Our first study uses a large dataset of more than five million posts to quantify ephemerality in /b/. We find that most threads spend just five seconds on the first page and less than five minutes on the site before expiring. Our second study is an analysis of identity signals on 4chan, finding that over 90% of posts are made by fully anonymous users, with other identity signals adopted and discarded at will. We describe alternative mechanisms that /b/ participants use to establish status and frame their interactions.
