Cyber-Bullying In High School: Associated Individual And Contextual Factors Of Involvement, Marissa Alexis Feldman

USF Tampa Graduate Theses and Dissertations

For the past several decades, researchers have extensively investigated the impact of bullying on the nation's youth. Although we may now have a better understanding of these maladaptive behaviors, recent technological advances have created a new forum for bullying. The current study investigated adolescent experiences with cyber-bullying using a self-report survey. Youth (N=2,086) from five high schools (grades 9-12) were surveyed to identify individual, peer, parenting, and school factors hypothesized to be related to involvement in cyber-bullying as a victim, perpetrator, or both. Results indicated that cyber-involvement was related to a variety of psychosocial factors, with students who were both …

Navigating The Child Welfare System: An Exploratory Study Of Families' Experiences, Lianne Fuino Estefan

USF Tampa Graduate Theses and Dissertations

Growing up in a family environment that includes child maltreatment can result in an array of negative consequences for children, including health, behavioral, developmental, and social difficulties, and these consequences can persist over the lifetime. Families who have come to the attention of child welfare services for child maltreatment are at particularly high risk for experiencing multiple concurrent problems, including intimate partner violence, substance abuse, and mental health issues, as well as other family challenges. It is essential to intervene effectively with this population. However, there are few qualitative studies of parent experiences in the child welfare system through which …

Secondary Principals At The Center Of School Reform: Portraits Of Leadership, Daniel James Evans

USF Tampa Graduate Theses and Dissertations

The number of studies related to school reform and principal leadership styles confirms both the interest in how the two might be related and the enigma that schools and principals present as research topics. The art and science of school reform is hard to figure. While many studies attempt to make sense of an overlapping and competing set of variables that are found in good schools, nearly all studies have confirmed some support for principals as a key ingredient to school improvement.

This study seeks to add to the increasing amount of research related to principal leadership styles in an …

A Pilot Study Of Small-Scale Variations In Outdoor Benzene Concentrations, Samantha Catherine Fridh

USF Tampa Graduate Theses and Dissertations

Benzene is an important toxic chemical in urban air and known human carcinogen released substantially by mobile sources. It's important to understand the spatial variation of benzene concentrations in order to understand exposures of susceptible sub-populations such as children and minority groups. Current monitoring networks use large and expensive air samplers that require electricity and restrict the location and number of samplers, not allowing for fine spatial resolution data.

The goals of this study are to develop and evaluate protocols for passive sampling and analysis of ambient benzene concentrations, and conduct a pilot study investigating small-scale variations over an area …

Although program personnel from all youth service programs in this …

The Effect Of Unexpected Exercise Duration On Rating Of Perceived Exertion In An Untrained, Sedentary Population, Lisa M. Giblin

USF Tampa Graduate Theses and Dissertations

The Borg Rating of Perceived Exertion (RPE) scale is a primary tool for researchers and practitioners in exercise science to describe the intensity level subjects are experiencing when participating in exercise sessions. It has recently been suggested that RPE is not simply the direct result of interpretation of physiological changes as originally postulated, but is also influenced by affect, past experience, and time to completion, a concept coined as teleoanticipation.

The purpose of this study was to determine the role of teleoanticipation in a sedentary population, by examining the effect unexpected increases in exercise duration on rating of perceived exertion …

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 …

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 …

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 …

Electronic Structure Characterization Of Nanocrystalline Surfaces And Interfaces With Photoemission Spectroscopy, Sebastian Gutmann

USF Tampa Graduate Theses and Dissertations

In this study, photoemission spectroscopy (PES) was used to investigate the electronic properties of nanocrystalline titanium dioxide (TiO₂), zinc oxide (ZnO), and cadmium selenide (CdSe). Electrospray deposition technique enabled the preparation of thin films in vacuum from a dispersion prepared outside the vacuum chamber. This method also allowed the step-wise formation of interfaces and the monitoring of the evolution of the electronic structure with intermittent PES characterization.

The work function of nanocrystalline TiO₂ and ZnO was measured with ultraviolet photoemission spectroscopy (UPS) and low-intensity x-ray photoemission spectroscopy (LIXPS). Measurements on environmentally contaminated surfaces revealed an instantaneous and …

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 …

The purpose of this qualitative framing study is to analyze the dominant frames that were reflected in the news coverage of two separate Presidential speeches marking the proposed cessation of combat operations in Operation Iraqi Freedom. 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 …

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 …

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 …

The Relationship Of Principal Resiliency To Job Satisfaction And Work Commitment: An Exploratory Study Of K-12 Public School Principals In Florida, Jason Pepe

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate characteristics associated with resilient school leaders. Principals juggle multiple responsibilities and work under increasingly stressful conditions. Despite recent role changes, added job responsibilities, and increased accountability, some principals remain remarkably resilient while working in a tumultuous environment. Using Henderson and Milstein's (2003) definition, principal resiliency was described as "the capacity to spring back, rebound, successfully adapt in the face of adversity, and develop social, academic, and vocational competence despite exposure to severe stress or simply to the stress that is inherent in today's world" (p. 7). This empirical study tested the theory …

"We Have Never Known What Death Was Before"--A Just War Doctrine Critique Of U.S. History Textbooks, Mark Pearcy

USF Tampa Graduate Theses and Dissertations

Textbooks are a significant element of the social studies curriculum and teacher pedagogical choice (Apple, 2004; Apple & Christian-Smith, 1991). Students' views of American history are dramatically affected by the textbook narratives to which they are exposed, and teachers often tilt their curricular choices based on the textbooks available to them (Luke, 2006; Schug, Western & Enochs, 1997). The history of our nation's armed conflicts is often presented, through our textbooks and our pedagogy, as a history of reluctant violence, which promotes a particular moral agenda that exerts control over our students' future beliefs and decisions. This is particularly important …
