American Extremism: An Evolutionary Process, Christopher Young, Michael Damian Tucker

Journal of Strategic Security

This article critically examines the historical definitions of American right-wing extremism as utilized by the media, political community, academia, and the government. We suggest that the historical definitions of the right wing are inadequate and fail to describe extremism accurately and consistently. Using evolutionary game theory, this article further argues that right-wing extremism (and left wing) is based on an evolutionary process to secure social existence and will rise as predators challenge historical hierarchical systems.

New Petrographic And Geochemical Constraints On Pre-Eruptive Storage Conditions And Their Control On Eruptive Styles In Martinique’S Recent Volcanic Systems, Abigail Martens

USF Tampa Graduate Theses and Dissertations

This dissertation investigates the volcanic systems of Martinique Island, focusing on magma storage conditions, magmatic evolution, and eruption dynamics. Chapter 3 presents a petrographic analysis of volcanic rocks from the island’s old, intermediate, and recent arcs, examining the evolution of plagioclase textures and the increasing abundance of other mineral phases, such as pyroxene, amphibole, olivine, and quartz, which provide insights into changing magmatic conditions. The main research is divided into two projects. Chapter 4 addresses the pre-eruptive storage conditions (pressure and temperature) of magmas beneath recent (<5 Ma) volcanic complexes (Morne Jacob, Piton du Carbet, Trois Îlets, Mt. Conil, and Mt. Pelée), exploring magma evolution, crystallization, and the role of lower crustal injections and flank collapses in triggering eruptions. Results reveal variable magma storage depths (<6 km), with significant temperature and pressure variations, indicating complex magmatic systems. Chapter 5 focuses on the Roches-Genty ignimbrite in southwestern Martinique, investigating its stratigraphy, geochemistry, and age using field mapping, grain size analysis, and 40Ar/39Ar dating. The study identifies two distinct sub-Plinian eruptive phases associated with the Dizac ignimbrite, with ages of 3.37 ± 0.14 Ma and 2.10 ± 0.26 Ma, providing insights into past explosive volcanic activity. Geochemical analysis confirms an andesitic composition, similar to regional volcanic systems. This dissertation enhances understanding of Martinique’s volcanic history, providing valuable insights into magmatic processes and eruption dynamics, with implications for volcanic hazard assessments in the Lesser Antilles.

The Prideful Ass: Using Augustine's Neoplatonic Theory Of Sin To Investigate Curiosity In Apuleius' Golden Ass, Danielle E. Booth

USF Tampa Graduate Theses and Dissertations

Ancient discourse about the beneficial yet predominantly dangerous role of curiosity inattaining knowledge was prevalent in the Roman Empire around the 2nd century C.E. when the North African author, Apuleius, composed his Latin novel, the Golden Ass. Although there is no shortage of modern scholarship that focuses on how Apuleius dramatizes obsessive intrigue by means of his protagonist, Lucius, contemporary publications seldom reorient the discussion to consider how unclear he is about the unstated source of curiosity, as I do in the following thesis. Approaching this topic through the context of ancient Neoplatonism, I argue Augustine of Hippo – a …

The results of the DA were used to calculate the probability of a specific topography of attention following a problem behavior P(SR/B) and the unconditional probability of a specific topography of attention in the absence of problem behavior divided by all occurrences of that topography UP(SR-B/SR). …

Distributed Repeaters For Extending The Range Of Harmonic Rf Tags, Trevor Saunders

USF Tampa Graduate Theses and Dissertations

Passive harmonic Radio Frequency (RF) tags are highly advantageous compared to theiractive counterparts due to their ability to operate effectively in environments that are cluttered or where access to the tag for battery maintenance is challenging, dangerous and/or time consuming. They are also resistant to the local oscillator (LO) phase noise in radar applications where the doppler frequency from slow moving targets is buried beneath the noise. One of the major constraints of passive harmonic RF tags, however, lies in their operating range and the significant amount of power required to overcome the conversion loss and activate the nonlinear device …

Vietnam Syndrome And The Genetic Consequences Of Agent Orange Poisoning: A Materialist Approach, Moriah M. Haley

USF Tampa Graduate Theses and Dissertations

The aim of this thesis was to propose and apply a materialist approach to “Vietnam Syndrome” found at the intersection of masculinity, disability, and state power as it manifests in modern military strategy. Through an analysis of the physical veteran body rendered infertile from Agent Orange poisoning during the Vietnam War, the material conditions of infertility are found to have threatened the hegemonic masculinity on which the military relied for its justification and continuation amongst young American men. The turn to technological warfare was intended to remedy the insufficiency of the military body, but the solution was costly and ineffective …

“Call It What You Want” Analyzing Taylor Swift’S Communication Strategies During Public Controversies, Isabella Cuello

USF Tampa Graduate Theses and Dissertations

This study examines Taylor Swift’s crisis communication strategies during public controversies, particularly her disputes with Kanye West and Kim Kardashian between 2016 and 2019.

Through a thematic analysis of 72 lifestyle journalism articles (in U.S. based publications from 2016-2019), the findings reveal that Swift strategically navigated public scrutiny by reclaiming negative imagery, such as the snake symbol, and leveraging social media to reframe her public persona. The study …

Protracting The Immediate: Time As Form In Contemporary Horror, Kennedy Kelley

USF Tampa Graduate Theses and Dissertations

This thesis examines the expression and experience of temporality in horror films of the last decade. Whereas early twenty-first century horror was characterized by high-octane jump scares, current horror is marked by contemplative slowness. I argue that the elongated duration of recent horror extends an experience of indeterminate anxiety that attunes us to an expansive relationality, offering a corrective not only to contemporary logics of immediacy, but also to the frequently constricting nature of embodiment as a theoretical concept. Recent horror scholarship tends to center sensuous propinquity in response to a long history of gaze theory’s disembodied passivity. While these …
