Understanding Eating Boundaries: A Study Of Vegetarian Identities, Susan Kremmel

USF Tampa Graduate Theses and Dissertations

My research uses participants' understandings to look at how people define and use the identities and categories of "vegetarian" and "meat-eater." My research examines what it means to be vegetarian, how ideals and moral hierarchies are understood, and how issues of identity importance, social support, and boundary work are components of vegetarian identity construction processes. My research highlights the unmarked character of the meat-eating identity and investigates the variations and complexities of eating behaviors and identities. Learning more about how both vegetarians and meat-eaters construct vegetarian identities contributes to our understanding of identities and how, despite ambiguities, people experience identities. …

An Investigation Into The Antifungal Activities Of N-Thiolated Beta- Lactams Against Selected Candida Species, Marci Culbreath

USF Tampa Graduate Theses and Dissertations

β-lactam antibiotics have long been a reliable course of treatment for bacterial infections. However, with recent increases in resistance and rising populations of immunocompromised patients new β-lactams have been synthesized and tested. The Turos laboratory has recently discovered novel β-lactams that have a mode of action distinct from penicillin and other β-lactam antibiotics as cell lysis is not observed. In the current investigations, these compounds are shown to also have antifungal properties. The rising incidence and prevalence of invasive fungal infections has become an increasing concern. The most common fungal pathogens involved in these infections are species in the genus …

Impacts Of Rainfall Events On Wastewater Treamtent Processes, Erin K. Mcmahan

USF Tampa Graduate Theses and Dissertations

Current research is revealing that stormwater can carry pathogens and that this stormwater is entering wastewater treatment facilities. During periods of intense rainfall, not only can stormwater carry higher amounts of pathogens, but it also increases the flow rate to the wastewater treatment facility. In many instances, the flow rate exceeds the facilities' treatment capacity and can impact treatment performance. The purpose of this study was to identify whether wastewater treatment is impaired during periods of increased rainfall, and to compare current policies that address this issue. The study was conducted using a case study approach to analyze historical precipitation …

Vision And Disease In The Napoleonic Description De L’Egypte (1809-1828): The Constraints Of French Intellectual Imperialism And The Roots Of Egyptian Self-Definition, Elizabeth L. Oliver

USF Tampa Graduate Theses and Dissertations

This study analyzes the travel conventions manifest in the engravings of the

thirty-volume

Description de l’Egypte produced as a result of the Napoleonic campaign

to Egypt in 1798 and published between 1809 and 1828. The first chapter examines the

discourse established on Egypt in travelogues throughout the eighteenth century prior to

the invasion of the country. I argue that the perceptions developed around the country

did not stem from actual experience, but from political and economic motivations that

cast Egypt in a light favorable for occupation.

I examine how this perception was challenged during the collapse of distance

between the …

The Enthymeme’S Role In Modern Discourse, Ryan Meehan

USF Tampa Graduate Theses and Dissertations

In this paper, I wish to demonstrate how enthymemic argument pervades modern discourse. First, I will define the enthymeme in Aristotelian terms and compare its qualities to its sibling, the syllogism. Next, I will attempt to demonstrate how the enthymeme functions, paying close attention to its psychological effects as well as analyzing how the media helps promote enthymemic discourse. Finally, I will propose a way that composition instructors can harness the idea of the enthymeme to facilitate critical thinking in the classroom. The purpose of the paper is to provide evidence that a rebirth of this classical term is in …

Image Restoration Theory: An Empirical Study Of Corporate Apology Tactics Employed By The U.S. Air Force Academy, Glen F. Roberts

For this thesis study, a content analysis was conducted of media releases and stories produced by the U.S. Air Force regarding a series of sexual assaults at the Air Force Academy in 2002. The purpose of the study is two-fold. First, it determines the image …

Control Of Hydrogen Sulfide From Groundwater Using Packed-Bed Anion Exchange And Other Technologies, Camilo Romero Cotrino

USF Tampa Graduate Theses and Dissertations

Hydrogen sulfide imparts odors and taste to drinking water and can be corrosive to distribution systems. Groundwater sources used to produce drinking water tend to have sulfide concentrations ranging from below 0.1 to over 3 mg/L. Under anaerobic conditions, hydrogen sulfide can be formed from reduction of sulfate and elemental sulfur through chemical or biological reactions. Therefore, to decrease the potential for hydrogen sulfide in water systems, control of all forms of sulfur should be consistent.

Hydrogen sulfide in groundwater can be controlled through conversion or removal mechanisms. Conversion reactions result from chemical or biological reactions that oxidize hydrogen sulfide …

Stormtroopers Among Us: Star Wars Costuming, Connection, And Civic Engagement, Dava L. Simpson

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to examine the bonds that form between people as consumers of popular visual media and to discuss the relationship and impact of the resulting subcultures on the larger culture. Star Wars costumers offer a magnified glance at some of the ways in which people engage with images. As reflections of popular culture, costumers display their textual devotions and opinions; they embody spectatorship by reincarnating their favorite characters and contexts from text-bound sources. Moreover, they embrace modes of visual representation by performing the roles of both image consumer and image producer. I strive to understand …

“Fit For The Reception Of Ladies And Gentlemen”: Power, Space, And Politeness In Eighteenth-Century Anglo-Atlantic Playhouses, Troy Thompson

USF Tampa Graduate Theses and Dissertations

Eighteenth-century English men and women ventured to the playhouse for a night of festive revelry and entertainment. Despite the raucousness (compared to our vision of a night at the theatre), theatergoing was a polite endeavor and as such equipped with the material pleasantries of bourgeois society. But unlike other spaces reserved for the middle and upper classes, all manner of people could and did attend the theatre. Thus, particular methods of physically and visually separating social classes arose within the eighteenth-century playhouse.

In this thesis, I investigate these material phenomena, particularly the ways in which theatre managers, players, as well …

The Mucilage Of Opuntia Ficus Indica: A Natural, Sustainable, And Viable Water Treatment Technology For Use In Rural Mexico For Reducing Turbidity And Arsenic Contamination In Drinking Water, Kevin Andrew Young

USF Tampa Graduate Theses and Dissertations

The use of natural environmentally benign agents in the treatment of drinking water is rapidly gaining interest due to their inherently renewable character and low toxicity. We show that the common Mexican cactus produces a gum-like substance, cactus mucilage, which shows excellent flocculating abilities and is an economically viable alternative for low-income communities. Cactus mucilage is a neutral mixture of approximately 55 high-molecular weight sugar residues composed basically of arabinose, galactose, rhamnose, xylose, and galacturonic acid. We show how this natural product was characterized for its use as a flocculating agent. Our results show the mucilage efficiency for reducing arsenic …

Precipitative Softening And Ultrafiltration Treatment Of Beverage Water, Jorge T. Aguinaldo

USF Tampa Graduate Theses and Dissertations

Lime softening, chlorination, clarification and filtration have been long recognized treatment processes for beverage water specifically the carbonated soft drink (CSD) because it provides consistent water quality required for bottling plants, however these processes are becoming uneconomical and causes more problems than the benefits they offer. These processes require very large foot print, occupy large plant volume, and generate large volume of sludge which causes disposal problems. Chlorination produces trihalomethanes (THMs) and other by-products which are detrimental to health and imparts tastes to the final products. Using the newly developed submerged spiral wound ultrafiltration membranes in conjunction with lime softening …

Rethinking The Monumental: The Museum As Feminist Space In The Sexual Politics Exhibition, 1996, Devon P. Larsen

USF Tampa Graduate Theses and Dissertations

Rethinking the monumental suggests not only a reconsideration of Judy Chicago’s controversial installation The Dinner Party (1979)--as displayed in the group feminist art exhibition, Sexual Politics: Judy Chicago’s Dinner Party in Feminist Art History--but also refers to an unfixing of the monumental position of power afforded the museum and a re-invigoration of the debate in feminist visual art regarding the use of the female body. I use the Sexual Politics exhibition, curated by Amelia Jones for the University of California at Los Angeles Armand Hammer Museum and Cultural Center (1996) as an indicator of the museum as feminist space. Sexual …

Extending this position through the underlying research, it is expected that the audiences in the United States, one of the largest cultural product exporters, may have shaped certain perceptions on the scarcity of Korean films in their domestic film market. By studying the users in an internet film discussion community, this research aims to provide useful ideas about how American audiences perceive Korean films. This qualitative case study conducted a content analysis of the actual postings by the participants …

Intelligent Design And Evolutionary Theory: Legal Battles And Classroom Relevance For School Leadership, Larry R. Plank

USF Tampa Graduate Theses and Dissertations

Evolutionary theory in the scientific curricula of public education has been scrutinized by religious societies for the better part of a century around the globe. Although Darwin’s explanation of the mechanism of evolution—the process of natural selection—is widely accepted by scientists in the United States and other industrialized nations, the U.S. has lagged behind these other countries in accepting evolutionary theory in public school curricula. The debate of what to include in textbooks and classroom lessons is one of America’s most controversial issues. The creationist worldview of life’s origins has been incorporated into science curriculum as a direct challenge to …

A New Type Of Insurgency? A Case Study Of The Resistance In Iraq, Stephen D. Curtas

USF Tampa Graduate Theses and Dissertations

Insurgency is considered to be the principal form of conflict in the world today. Since the end of WWII, large-scale conventional war between states has been minimal. In Iraq, a band of insurgents are attempting to defy the strongest power in the world. This insurgency in Iraq may be the beginning of a new phenomenon of insurgency conflict.

This thesis argues that the Iraqi insurgency has no center of gravity, with no clear apparent leader or leadership. As seen in other examples of insurgency throughout history, no leadership has emerged in response to any of the conditions present in Iraq. …
