Feasibility Of Wastewater Reuse For Fish Production In Small Communities In A Developing World Setting, Joshua James Girard

USF Tampa Graduate Theses and Dissertations

Eradicating poverty, malnutrition, and the burden of disease have been included as three of the major issues facing the world. The United Nation member countries, having set forth the Millennium Development Goals, have committed themselves to solving these problems. Two major factors which affect solutions to these problems are increasing water stress and implementing improved sanitation. Integration of tilapia aquaculture and reuse of wastewater has been suggested as a solution which addresses both of these factors. The objective of this study is to examine the feasibility, and explore the benefits and drawbacks, to implementing small community wastewater fed (WWF) aquaculture …

The Role Of Hiv-1 Proteins In Alzheimer's Disease Pathology, Brian Nelson Giunta

USF Tampa Graduate Theses and Dissertations

Prevalence of HIV-associated cognitive impairment is rising, the worst form of which is HIV-associated dementia (HAD). The disease is fuiled by a chronic innate type pro-inflammatory response in the brain which is highly dependent upon the activation of microglia. We first created an in vitro model of HAD composed of cultured microglial cells synergistically activated by the addition of IFN-gamma and the HIV-1 coat glycoprotein, gp120. This activation, as measured by TNF-alpha and NO release, is synergistically attenuated through the alpha7nAChR and p44/42 MAPK system by pretreatment with nicotine, and the cholinesterase inhibitor, galantamine. As these medications have been FDA …

USF Tampa Graduate Theses and Dissertations

The United Nations Millennium Development goals aim to make improvements in access to potable water. In the Bocas del Toro region of Panama, rainwater harvesting systems are making that goal more attainable. Rainwater harvesting, especially in rural, difficult access areas, may be a viable water source improvement that will allow a greater population to access improved water. This study uses the Carnegie Mellon University Economic Input-output Life Cycle Assessment tool to assess the embodied energy of plastic and ferrocement rainwater harvesting systems in rural Panama. Rainwater harvesting systems are assessed as source improvement technologies that increase access to potable water. …

"The Wound And The Voiceless: The Insidious Trauma Of Father-Daughter Incest In Six American Texts", Christine Lynn Grogan

USF Tampa Graduate Theses and Dissertations

Cathy Caruth's pioneering study of trauma and the posttraumatic forges a connection between the psychoanalytic theory of traumatic experience and the literary as such. Since trauma defies linguistic processing, she explains, the language used to describe it will always be figural. For this reason Caruth privileges imaginative literature, with its highly mediated nature, as a means of representing the otherwise "unclaimed" experience of trauma. Her influential reflections inform a crucial direction within trauma studies: the search for a narrative voice that articulates trauma effectively.

But how should we think about trauma that is not a singular "event" but a chronic …

Relationship Between Cancer-Related Fatigue And Depression: A Pilot Study, Gloria Michelle Guess

USF Tampa Graduate Theses and Dissertations

Fatigue is one of the most bothersome symptoms reported by patients diagnosed with cancer, and research indicates that the majority of patients receiving chemotherapy report symptoms of fatigue. Fatigue can have an effect on quality of life; therefore, it is essential that healthcare providers gain a better understanding and recognition of fatigue.

Fatigue can also be a symptom of depression. Depression is another prominent symptom reported by patients diagnosed with cancer. Unfortunately, there are similarities between the symptoms of depression and fatigue making it difficult for health care providers to distinguish between the two. This study utilizes the subscale of …

The Mediating Role Of Social Support And Fulfillment Of Spiritual Needs In End Of Life Care, Kimberley A. Gryglewicz

USF Tampa Graduate Theses and Dissertations

End of life (EOL) caregiving can be a daunting and challenging endeavor as caregivers adjust to the ever-changing care demands associated with dying. Increased personal care, assisting with symptom and medication management, and attending to the emotional and spiritual needs of the dying person require caregivers to learn new tasks and to assume new roles such as social worker, nurse, and chaplain. As families continue to play an essential role in meeting the health care needs of their dying loved ones, it is imperative for social workers to understand the complexities of the end of life caregiving experience in order …

Internships In Public Relations And Advertising: The Nature Of The Experience From The Student's Perspective, Catherine Ann Gugerty

USF Tampa Graduate Theses and Dissertations

This qualitative content analysis examines the nature of experience of public relations and advertising interns. Three decades of scholarly inquiry into the internship experience has provided little insight into the actual experience of the interns themselves. Yet what is learned directly from their individual experience can provide both educators and professionals valuable insight for enhancing the learning process. The following study is a qualitative content analysis of journals and focus groups of undergraduates enrolled in public relations and advertising internships/practicums. The interns' experience follows four themes: (1) the perception of importance; (2) perceived learning benefits; (3) influence of supervisors; and …

Evaluating Lethal And Sub-Lethal Effects Of Catch-And-Release Angling In Florida's Central Gulf Coast Recreational Atlantic Tarpon (Megalops Atlanticus) Fishery, Kathryn Yvonne Guindon

USF Tampa Graduate Theses and Dissertations

Atlantic tarpon are sought after because of their fighting ability on various tackle and support a popular, lucrative and predominantly catch-and-release recreational fishery in Florida. They are not commercially harvested or consumed by the general public, therefore assessing effects of catch-and-release angling on tarpon survival is critical to a sustainable fishery. Tarpon caught on artificial breakaway jig and traditional live bait fishing charters in Boca Grande Pass (n=42) and trips from the recreational fishery of Tampa Bay (n=40) were tagged with ultrasonic transmitters and tracked up to 6 hours immediately following release to estimate post-release mortality. Of the 82 tagged …

Design And Testing Of A Motion Controlled Gait Enhancing Mobile Shoe (Gems) For Rehabilitation, Ismet Handzic

USF Tampa Graduate Theses and Dissertations

Persons suffering central nervous system damage, such as a stroke, coma patients, or individuals that have suffered damage to the spinal cord, brainstem, cerebellum, and motor cortex, sometimes develop an asymmetric walking pattern where one leg does not fully swing backward. This uneven gait hinders these individuals in properly and efficiently moving through everyday life.

Previous research in humans and various animals has introduced a split belt treadmill to analyze possible rehabilitation, which can recreate a correct gait pattern by altering the speed of each track. Gait adaptation was achieved by having the split belt treadmill move each leg at …

Statistical Analysis And Mechanistic Modeling Of Water Quality: Hillsborough Bay, Florida, Keith Hackett

USF Tampa Graduate Theses and Dissertations

Nutrient pollution has been identified as a significant threat to U.S. coastal and estuarine water quality. Though coastal and estuarine waters need nutrients to maintain a healthy, productive ecosystem, excess nutrients can lead to eutrophication. There are significant potential negative consequences associated with eutrophication, including loss of habitat, loss of economic activity, and direct threats to human health. Hillsborough Bay experienced eutrophication in the 1960s and 1970s due to a rapidly growing population and associated increases in nutrient pollution. These eutrophic conditions led to more frequent phytoplankton and macroalgae blooms and declines in seagrasses. To address these problems, a series …

Using Multi-Paradigmatic Interventions: Gauging The Possibilities Of Using Culturally Responsive Pedagogy Within A Response To Intervention Framework, Vanessa Hein

USF Tampa Graduate Theses and Dissertations

There exists a highly charged debate about whether or not the Problem Solving/Response to Intervention (PS/RtI) model works alone in lowering the rate of special education referrals for students in an inclusive learning environment. This study seeks to explore the incorporation of a culturally responsive pedagogy (CRP) into the PS/RtI framework, with the assumption that it would assist teachers with PS/RtI implementation as well as enhance their classroom learning environment. Interviews with PS/RtI coaches and elementary school teachers implementing PS/RtI are coded using inductive and deductive strategies, using salient factors of both CRP and PS/RtI as indicators for a comparative …

In order to determine which frames emerged in the coverage of each speech, a content analysis of 105 articles from 4 national newspapers was conducted. Analysis included the week preceding and the week following each speech in an effort to capture the immediate coverage surrounding each address. The findings suggest that the dominate frames utilized were the economic consequences frame, the responsibility frame and …

Physical Models Of Amyloid Fibril Assembly, Shannon Elizabeth Hill

USF Tampa Graduate Theses and Dissertations

Formation of large fibers and plaques by amyloid proteins is recognized as the molecular hallmark of an increasing number of human disorders, including Parkinson's disease, Alzheimer's disease and even type II diabetes. The broader objective of my research is to unravel the basic mechanisms that initiate and regulate fibril formation by amyloidogenic proteins. This objective is significant because even basic aspects of how fibril formation proceeds from a soluble, monomeric protein to an insoluble amyloid fibril remain much debated. Furthermore, there is increasingly strong evidence suggesting that intermediates of the aggregation process, with properties distinct from those of mature fibrils, …

Park Access And Distributional Inequities In Pinellas County, Florida, Kyle Ray Hirvela

USF Tampa Graduate Theses and Dissertations

Although environmental justice research has traditionally focused on environmental disamenities and health hazards, recent studies have begun to examine social inequities in the distribution of urban amenities such as street trees and parks that provide several direct and indirect health benefits to local residents. This thesis adds to this knowledge by evaluating distributional inequities in both distribution and access to parks in Pinellas County, the most densely populated and one of the most racially segregated counties in Florida. An important objective was to determine if neighborhoods with lower levels of park access are more likely to contain a significantly higher …

Utilizing A Computational Model For The Design Of A Passive Dynamic Walker, Craig Alan Honeycutt

USF Tampa Graduate Theses and Dissertations

Recent interest in using passive dynamic walkers (PDWs) for gait rehabilitation studies has presented a need for a robust, easily built mechanism. Unfortunately, these passive robots are hypersensitive to many variables outside of the usual design considerations that are studied when constructing them. By accentuating previous failures instead of suppressing them, this thesis presents a number of problematic situations commonly experienced when testing and tuning a PDW.

Further, through a complete design of a 4-legged PDW with knees, simple design axioms brought about by myself and others are put into a practical context and applied directly to design. This thesis …

From Source To Sink: An Isotopic Perspective On The Biogeochemical Relationship Between The Everglades And Florida Bay, Ana Maria Hoare

USF Tampa Graduate Theses and Dissertations

Increasing human populations and activities in coastal areas have led to high nutrient loading and estuarine ecosystem decline. Natural hydrological patterns in South Florida have been drastically altered by changes in water management and land use practices. As a result Florida Bay has experienced a series of negative ecosystem effects including hypersalinity events, degradation of water quality, and harmful algal blooms and declines in upper trophic level populations. To remediate ecosystem decline in Florida's coastal ecosystems, the Comprehensive Everglades Restoration Plan proposes to restore a more natural hydrologic flow in the Everglades. It is expected hydrologic restoration efforts will change …

Aura, Self, And Aesthetic Experience, Marshall Battani

Contemporary Aesthetics (Journal Archive)

Aesthetic experiences are generated in encounters with cultural objects and such experiences are marked by the free play of cognitive and numinous experience unstructured by concepts. Kant’s famous three types of pleasure, made infamous in social theory by Pierre Bourdieu, are examined in relation to the critical theoretical concept of aura, the social psychology of “flow,” and cognitive explanations of perception to explain experience in aesthetic fields. Theories of aesthetic experience developed at the crossroad of critical social thought and cognitive science hold promise for a social analysis able to avoid the usual sociological pitfalls of either ignoring aesthetics or …

Investigating Technological Organization At The Buck Lake Site (45pi438) In Mount Rainier National Park Using A Lithic Debitage Analysis, Michael Charles Schurke

Dissertations and Theses

Few lithic analyses have been conducted or published on collections from Mount Rainier National Park (MORA). This study's lithic debitage analysis, and investigation of hunter-gatherer technological organization through time, contributes to the knowledge base and understanding of how hunter-gatherers used subalpine environments in MORA. The debitage sample is from archaeological excavations between 2005 and 2007 at a Buck Lake Site (45PI438) activity area in the subalpine environmental zone. Two cultural components were examined: the pre-Mount St. Helens Yn tephra component (before 3500 RCYBP) is thought to represent a forager-like mobility strategy and the post-Mount St. Helens Yn tephra component (after …

Deforestation, Drought And Humans: New Discoveries Of The Late Quaternary Paleoenvironment Of Rapa Nui (Easter Island), Candace Lynn Gossen

Dissertations and Theses

The mystery of the trees of Rapa Nui (Easter Island) is a complex problem within a dynamic ecosystem. With new physical cores from the volcanic crater lake Rano Kao, this dissertation uncovers a detailed 15,000 year ecological history of Easter Island and its climatic variability. New radiocarbon dating methods establish a more precise chronology which shows that the island before human habitation was very different than what we know today. It had a simple but prolific ecology that transitioned into a barren grassland. What factors caused the transition are unclear but are likely to be human related. As the forests …

Informal Karst Education In The United States And Internationally, Leslie A. North

USF Tampa Graduate Theses and Dissertations

Despite the abundance of karst terrains and the important role they play in a wide variety of roles including supplying freshwater drinking supplies, no single, comprehensive study investigates the role of informal education for the improved understanding and protection of the terrains. Commonly overlooked anthropogenic karst disturbances partially occur because of the poor dissemination of scientific information to the general populace and policymakers and budgetary and time constraints of municipalities, thus generating a need to use informal education to fill these shortcomings. The purpose of this study was to: 1) establish the status of and quantify the amount of karst-related …

Research questions were answered using archival data collected from 474 caregivers who participated in HOT DOCS, a behavioral parent training program, between January 2009 through July 2010. The three objectives of the study were to (a) examine caregivers' perceived stress in relation to caregiver demographic variables (i.e., gender, marital status, level of education); (b) examine caregivers' perceived stress in relation to child demographic variables (i.e., levels of externalizing and internalizing behavior and …

My Bad Romance: Exploring The Queer Sublimity Of Diva Reception, Blake Paxton

USF Tampa Graduate Theses and Dissertations

This study explores the historic relationship between pop music divas and gay male fandom. It charts fan experiences from the early 60s with Judy Garland to contemporary times with pop diva Lady Gaga. This project also gives a description of the embodied experience of Brett Farmer’s “queer sublimity of diva reception.” Farmer (2005) argues that diva worship among gay men has become a queer sublimity, “the transcendence of a limiting heteronormative materiality and the sublime reconstruction, at least in fantasy, of a more capacious, kinder, queerer world” (p. 170). Using the methods of participant observation in drag performance and karaoke …
