Treasonous Patriot: A Comparative Content Analysis Of The Media's Portrayals Of Daniel Ellsberg And Edward Snowden, Kaylin Mcloud

Graduate Theses and Dissertations

On June 9, 2013, the world was introduced to Edward Joseph Snowden, a 29-year-old NSA contractor and the man responsible for the biggest leak of classified government documents in American history. Almost immediately, comparisons were drawn between Snowden and another famous whistleblower--Daniel Ellsberg, the man behind the 1971 release of the Pentagon Papers. The overwhelming rhetoric surrounding the comparison was that Ellsberg was a true American patriot and that Snowden was nothing like him, that he was a traitor. Despite Ellsberg's own claims that he and Snowden are exactly alike, the media still finds Snowden lacking when comparing him with …

Understanding The Evolution Of Aggregative Multicellularity: A Molecular Phylogenetic Study Of The Cellular Slime Mold Genera Sorodiplophrys And Pocheina, Alexander Tice

Opportunity, Temporal Patterns, And Successful Outcomes Of Far-Right Terrorism Incidents In The United States, Brent Ryan Klein

Graduate Theses and Dissertations

This thesis examines the impact that far-right terrorism opportunity structures and temporal patterns of precursor activity have on incident outcomes. Data from the American Terrorism Study (ATS) are extracted for several attributes of far-right opportunity, in addition to measures for temporal patterns of planning and preparatory behaviors. Bivariate and multivariate findings generally support expectations that target attractiveness and vulnerability, far-right group structures, and patterns of precursor activity are significantly associated with incident outcomes. The paper concludes with suggestions for future research and several implications for homeland security policy.

Policing And The Likelihood Of Terrorism: A Community Structural Approach To An Uncertain Relationship, Andy Bellamy Brooks

Graduate Theses and Dissertations

Prior research on terrorism has argued that local law enforcement play an important role in counterterrorism though the mechanisms by which the police should prevent terrorism are empirically unsettled and atheoretical in nature. Even less understood is how policing might differentially impact terrorism across specific ideological movements (e.g., far-right, environmental, Islamic extremism). Drawing from prominent sociological and criminological theories (i.e., Environmental perspectives, Social Disorganization, Conflict/Marxist) the current study addresses several key gaps in prior literature by utilizing data from the American Terrorism Study (ATS) paired with data from the FBI Uniform Crime Report and U.S. Census Bureau. Results suggest that …
