The Effects Of Scaling On Bite Force And Suction Index In The Eastern Hellbender (Cryptobranchus Alleganiensis), Nicholas Patrick Larghi

USF Tampa Graduate Theses and Dissertations

The hellbender (Cryptobranchus alleganiensis) is a salamander that grows over a large range of body sizes (2-74 cm total length) making it an ideal organism for examining the effects of body size on morphology and performance. The goal of this study is to investigate the morphology changes over ontogeny and change in

feeding ability. Cryptobranchus feeds on small aquatic insects as juveniles and shifts to crayfish as they get larger. Morphology can be expected to change as an organism grows larger, and because morphology and performance are closely linked, this morphological change can result in a change in …

The Strange Life And Stranger Afterlife Of King Dick Including His Adventures In Haiti And Hollywood With Observations On The Construction Of Race, Class, Nationality, Gender, Slang Etymology And Religion, Alan Thomas Lipke

USF Tampa Graduate Theses and Dissertations

Richard "King Dick" or "Big Dick" Crafus, Cephas, or Seaver(s) first attracted attention by his size, strength and the authority he exercised as leader of U.S. African American Prisoners of War in Britain during the War of 1812. After the War he was celebrated as a boxing pioneer, ceremonial King of Boston's black community and almost certainly auxiliary law officer. Very little has been known about his life, and much of that obscured by his black working-class status; his true standing within his own community remains mysterious. Yet paradoxically he's been made much of, in academic writing and fiction alike …

Eschatology In A Secular Age: An Examination Of The Use Of Eschatology In The Philosophies Of Heidegger, Berdyaev And Blumenberg, John R. Lup, Jr.

USF Tampa Graduate Theses and Dissertations

The topic of eschatology is generally confined to the field of theology. However, the subject has influenced many other fields, such as politics and history. This dissertation examines the question why eschatology remained a topic of discussion within twentieth century philosophy. Concepts associated with eschatology, such as the end of time and the hope of a utopian age to come, remained largely background assumptions among intellectuals in the modern age. Martin Heidegger, Nicolai Berdyaev, and Hans Blumenberg, however, explicitly addressed the subject in their philosophies. The impetus of this study is Heidegger's statement, "Being itself is inherently eschatological," which indicates …

Dead Man's Switch: Disaster Rhetorics In A Posthuman Age, Daniel Patrick Richards

USF Tampa Graduate Theses and Dissertations

When a disaster the magnitude of the Deepwater Horizon blowout and oil spill takes place, is it natural for the news media stories, investigative reports, and public deliberation to focus almost exclusively on finding the person or group responsible for such a horrendous scene. Rhetorically speaking, the discourse surrounding the event can be characterized as a reductive form of praise and blame rhetoric (epideixis). However, these efforts, while well-intentioned, are troublesome because searches for the one technical cause and the sole personal culpability are thwarted by the sheer complexity of the ecological, technological, scientific, institutional, and communicative network required for …

Inspiratory Breathing Exercises For Vocal Tremor: A Preliminary Study, Jessica Tayseer Hilo

USF Tampa Graduate Theses and Dissertations

Essential voice tremor (EVT) is a voice disorder that results from dyscoordination within the laryngeal musculature, which negatively impacts the symmetrical motion of the vocal folds. Several investigators have shown that individuals with EVT experience difficulty speaking and a reduced quality of life (QOL; Cohen, Dupont, & Courey, 2006; Verdonck-de Leeuw & Mahieu, 2004). While traditional voice therapy has been ineffective in lessening the severity of vocal tremor, a current approach (Barkmeier- Kraemer, Lato, & Wiley, 2011) designed to lessen the perception of vocal tremor has resulted in reported patient satisfaction with little actual change in voice quality. The present …

The Walls Are Closing In: Comparing Property Crime Victimization Risk In Gated And Non-Gated Communities, Nicholas Branic

USF Tampa Graduate Theses and Dissertations

In recent years, a growing proportion of the population has moved into gated communities in response to an increasingly pandemic fear of crime. While a sizable body of research has addressed fear of crime and perceived safety in gated communities, few studies have investigated actual rates of victimization. The studies that do compare victimization in gated and non-gated communities tend to be localized assessments and present mixed findings on the effectiveness of community gating as a form of protection from crime.

The present study utilizes a cross-section of National Crime Victimization Survey data to investigate the micro-level effects of living …

World Percussion Approaches In Collegiate Percussion Programs: A Mixed-Methods Study, Patrick Michael Hernly

USF Tampa Graduate Theses and Dissertations

As world percussion has grown in popularity in American colleges and universities, two main problems have emerged. The first problem is that no known source exists detailing how percussion instructors have incorporated world percussion into their collegiate teaching. A review of the literature has highlighted four main approaches to incorporating world percussion in collegiate percussion programs: applied study, group performance, travel experiences, and guest expert visits. The second problem is that systematic research on world percussion traditions has been carried out much more often by music education researchers, anthropologists, and ethnomusicologists than by percussionist-performers, so the relationship between theory and …
