The Role Of The Interruption In Young Adult Epistolary Novels, Betty J. Herzhauser
The Role Of The Interruption In Young Adult Epistolary Novels, Betty J. Herzhauser
USF Tampa Graduate Theses and Dissertations
Within the genre of young adult literature, a growing trend is the use of epistolary messages through electronic methods between characters. These messages are set apart from the formal text of the narrative of the novel creating a break in the text features and layout of the page. Epistolary texts require a more sophisticated reading method and level of interpretation because the epistolary style blends multiple voices and points of view into the plot, creating complicated narration. The reader must navigate the narrator’s path in order to extract meaning from the text. In this hermeneutic study, I examined the text …
Heart Of The Beholder: The Pathos, Truths And Narratives Of Thermopylae In _300_, James Christopher Holcom
Heart Of The Beholder: The Pathos, Truths And Narratives Of Thermopylae In _300_, James Christopher Holcom
USF Tampa Graduate Theses and Dissertations
This thesis argues that critical understanding of historical narratives needn’t be limited to cold, clinical applications of logic and reason. By doing a close textual reading of Frank Miller and Lynn Varley’s graphic novel, 300 and Zack Snyder’s 2007 film adaptation, I posit that critical analysis of popular narratives is better served when pathos takes a central role. Traditional rhetorical criticism tends to favor empirical evidence and fact over emotional, narrative truth. Yet, the writing, recounting and interpretation of history are more akin to arts than sciences. Historical narratives are subject to the same influences and techniques that make poetry, …
Tampa Electric Company's Big Bend Utility Plant In Hillsborough County, Florida: A Case Study, Lynne M. Hodalski-Champagne
Tampa Electric Company's Big Bend Utility Plant In Hillsborough County, Florida: A Case Study, Lynne M. Hodalski-Champagne
USF Tampa Graduate Theses and Dissertations
This is an in-depth analysis of coal fire burning power plants, their effects on human health and the environment. It also employed case study data from Tampa Electric Company’s Big Bend facility to examine environmental infractions at that facility. Tampa Electric Company’s Big Bend Utility Plant, violated the Clean Air Act, which led to a lawsuit filed by the Department of Justice on behalf of the United States Environmental Protection Agency and the Florida Department of Environmental Protection in 1997. This case study details the lawsuit, and subsequent settlement as well as Tampa Electric Company’s record of compliance since 2000. …
Evidence Of Things Not Seen: A Semi-Automated Descriptive Phrase And Frame Analysis Of Texts About The Herbicide Agent Orange, Sarah Beth Hopton
Evidence Of Things Not Seen: A Semi-Automated Descriptive Phrase And Frame Analysis Of Texts About The Herbicide Agent Orange, Sarah Beth Hopton
USF Tampa Graduate Theses and Dissertations
From 1961 to 1971 the United States and the Republic of South Vietnam used chemicals to defoliate the coastal and upload forest areas of Viet Nam. The most notorious of these chemicals was named Agent Orange, a weaponized herbicide made up of two chemicals that, when combined, produced a toxic byproduct called TCDD-dioxin. Studied suggest that TCDD-dioxin causes significant human health problems in exposed American and Vietnamese veterans, and possibly their children (Agency, U.S. Environmental Protection, 2011). In the years since the end of the Vietnam War, volumes of discourse about Agent Orange has been generated, much of which is …
Tornado Fatalities: An In-Depth Look At Physical And Societal Influences, Heather Joann Key
Tornado Fatalities: An In-Depth Look At Physical And Societal Influences, Heather Joann Key
USF Tampa Graduate Theses and Dissertations
The purpose of this study is to model and determine significant predictors of tornado death index values, and to investigate these significant predictors and what makes people vulnerable to tornado fatalities through expert interviews. This study also provides an understanding of the study participant’s perceptions of their county’s vulnerability to tornado fatality and demonstrates a true integration of methods and fields by studying geographic, meteorological, and sociological phenomena by use of quantitative and qualitative methods. The study consists of two parts: 1) A quantitative exploration of variables hypothesized to predict Tornado Death Index (TDI) values, 2) A qualitative investigation to …
System Threats And Gender Differences In Sexism And Gender Stereotypes, Sophie Lois Kuchynka
System Threats And Gender Differences In Sexism And Gender Stereotypes, Sophie Lois Kuchynka
USF Tampa Graduate Theses and Dissertations
In the United States, women’s persistent gains in structural power may cause backlash among those motivated to preserve the status quo. The proposed study examines the conditions that prompt men and women to endorse sexism and promote gender stereotypes. System justification theory proposes that people are motivated to justify the socio-political system that governs them and threats to the stability of their system can increase individual’s motivated defenses. I expect men to show the strongest motivated defenses when the hierarchy is threatened or viewed as unstable, because to protect group-based interests men will reinforce the legitimacy of the system through …
Experimental Reporting And Networks Of Political Information: Lorenzo Magalotti's Framing Of Courts And Nature, Bradley L'Herrou
Experimental Reporting And Networks Of Political Information: Lorenzo Magalotti's Framing Of Courts And Nature, Bradley L'Herrou
USF Tampa Graduate Theses and Dissertations
This thesis explores changes in experimental reporting during the scientific revolution of the seventeenth century. In particular, I examine and compare some of the works of Count Lorenzo Magalotti, namely the Saggi di Naturali Esperienza or Essays on Natural Experiments and the Relazione d'Inghilterra. In 1667, as secretary of the Accademia del Cimento – the Tuscan experimental academy founded in 1657 – Magalotti (1637-1712) authored the Saggi, a collection of experimental reports. These reports included extensive written descriptions of experiments along with dozens of engravings depicting the instruments custom-made for the experiments. Magalotti also served as ambassador and agent of …
'She Shall Not Be Moved': Black Women's Spiritual Practice In Toni Morrison's The Bluest Eye, Beloved, Paradise, And Home, Rondrea Danielle Mathis
'She Shall Not Be Moved': Black Women's Spiritual Practice In Toni Morrison's The Bluest Eye, Beloved, Paradise, And Home, Rondrea Danielle Mathis
USF Tampa Graduate Theses and Dissertations
‘She Shall Not Be Moved’: Black Women’s Spiritual Practice in Toni Morrison’s The Bluest Eye, Beloved, Paradise, and Home argues that from The Bluest Eye, Morrison’s debut novel, to her 2012 novel, Home, Morrison brings her female characters to voice, autonomy, and personal divinity through unconventional spiritual work. The project addresses the history of Black women’s activist and spiritual work, Toni Morrison’s engagement with unconventional spiritual practice, and closes with a personal interrogation of the author’s connection to Black women’s spiritual practice.
Beauty Is Precious, Knowledge Is Power, And Innovation Is Progress: Widely Held Beliefs In Policy Narratives About Oil Spills, Brenda Gale Mason
Beauty Is Precious, Knowledge Is Power, And Innovation Is Progress: Widely Held Beliefs In Policy Narratives About Oil Spills, Brenda Gale Mason
USF Tampa Graduate Theses and Dissertations
Scholars from diverse perspectives have sought to understand the features and mechanisms that influence the design and implementation of public policy. Some (realists) have emphasized the role that material interests have played while others (idealists) have emphasized the influence of subjective ideas on ‘how policy means’ (Yanow 1996). Recently, observers in both camps have demonstrated curiosity in the influence of culture on policymaking and its consequences. Regrettably, this shared concern has not resulted in much collaboration across epistemological divides.
I argue that narrative analysis provides a way to bridge the divides by specifying an interpretive approach that identifies culture as …
Documenting Perceived Effectiveness Of Community-Based Health Promotion Coalitions: A Grounded Theory Approach, Alyssa Brooke Mayer
Documenting Perceived Effectiveness Of Community-Based Health Promotion Coalitions: A Grounded Theory Approach, Alyssa Brooke Mayer
USF Tampa Graduate Theses and Dissertations
Introduction: Community coalitions with public health-related missions are formal, semi-permanent, action-oriented partnerships comprised of community members, representatives of government agencies, policymakers, and academic partners. Despite their potential to promote sustainable change, coalitions have had mixed success in effecting long-term improvements in community health. There is a need to assist them in developing strategies for improving and sustaining their functionality. The purpose of this study was to improve understanding of the elements of coalition success and sustainability that are vital to health-related community-based participatory research.
Methods: Although the literature describes coalition functions for effecting sustainable programs and policies, most research reports …
Effects Of A Brief Relaxation Intervention On Stress-Related Eating, Laura Lynn Mayhew-Purcell
Effects Of A Brief Relaxation Intervention On Stress-Related Eating, Laura Lynn Mayhew-Purcell
USF Tampa Graduate Theses and Dissertations
The experience of stress may contribute to increased food consumption and selection of unhealthy food options. Resource depletion theory suggests stress temporarily depletes resources needed to regulate behavior. Depletions of self-control may result in subsequent failure to regulate eating behaviors, which is particularly salient in restrained eaters. Restraint theory posits people high in dietary restraint require significant effort to control eating. Emotional eating theory further suggests palatable foods may be used to regulate emotional stress reactions. Relaxation exercises to mitigate stress reactions are recommended in eating and weight management programs, but lack quality scientific support. The current study examined the …
Looking At Levels Of Medicalization In The Institutional Narrative Of Substance Use Disorders In The Military, Chase Landes Mccain
Looking At Levels Of Medicalization In The Institutional Narrative Of Substance Use Disorders In The Military, Chase Landes Mccain
USF Tampa Graduate Theses and Dissertations
The purpose of this research is to examine the institutional narrative of substance use disorders (SUDs) in the U.S. military and the extent to which it reflects the medicalization process. Three general research questions guided my analysis of the narrative surrounding SUDs in the military: (1) How does the military characterize the problems and resolutions of SUDs? (2) How and to what extent does this narrative reflect medicalization? (3) What are the limitations inherent in the institutional narrative of SUDs in the military? In order to address these questions, I draw on three conceptual lenses: (1) The work of Loseke …
Assessment Of The Impact Of Attention Deficit Hyperactivity Disorder On Type 1 Diabetes, Kellee Miller
Assessment Of The Impact Of Attention Deficit Hyperactivity Disorder On Type 1 Diabetes, Kellee Miller
USF Tampa Graduate Theses and Dissertations
Individual day-to-day management and effective control of type 1 diabetes (T1D) is ultimately driven by decisions made by the individual. Individuals with attention deficit hyperactivity disorder (ADHD) have a higher tendency to be inattentive, impulsive, and hyperactive. Attention deficits and impulsivity among adolescents and adults with T1D could result in poor diabetes management through infrequent self-monitoring of blood glucose and inadequate insulin dosing – key components of achieving optimal glycemic control.
This study included 7,380 adolescents and young adults, ages 13-25 years, participating in the T1D Exchange clinic registry (median age 17.4 years, duration 7.7 yrs, 50% female, 81% white). …
The Triumvirate Of Intersectionality: A Case Study On The Mobilization Of Domésticas In Brazil, Kristen Lei Nash
The Triumvirate Of Intersectionality: A Case Study On The Mobilization Of Domésticas In Brazil, Kristen Lei Nash
USF Tampa Graduate Theses and Dissertations
In this thesis, I look at the mobilization of the domestic workers in Brazil as a social movement. In Brazil, the domestic workers have managed to organize continuously for over eight decades using both informal and formal mechanisms to connect workers all over the country in unique ways. By viewing these women and the ways in which they have organized in the framework of a social movement, we can begin to identify their repertoires of contention and how those repertoires have contributed to the successes of the movement. In order to guide this investigation, I ask, how has the doméstica …
Obsidian Source Selection In The Early Bronze Age Cyclades, Jessica Anne Morgan
Obsidian Source Selection In The Early Bronze Age Cyclades, Jessica Anne Morgan
USF Tampa Graduate Theses and Dissertations
From excavations of burial complexes of the Early Bronze Age Cyclades (c. 3000-2200 BC) we know that obsidian was just as important and as widely consumed in burial contexts as it was in contemporaneous household contexts; Early Bronze Age Cycladic tomb assemblages are dominated by beautiful obsidian blades produced through a unique knapping technique reserved for burial contexts (Carter 2007; Dickinson 1994). The lack of sourcing studies in the area is an unfortunate pitfall in Aegean archaeology, as understanding patterns of source selection provides us with precious insight into the complex social structures and behaviors that characterized these ancient communities. …
Women’S Use Of And Decision‐Making Regarding Geo‐Social Networking Applications To Arrange Sexual Experiences, Shireen Mary Noble
Women’S Use Of And Decision‐Making Regarding Geo‐Social Networking Applications To Arrange Sexual Experiences, Shireen Mary Noble
USF Tampa Graduate Theses and Dissertations
The purpose of this thesis was to learn more about geo-social networking applications and how they are used by women to meet sexual partners. Currently, there are no known studies that have looked at heterosexually-oriented geo-social networking applications or at the way women have used these apps for heterosexual sexual encounters. This thesis attempts to begin to bridge this gap in the literature.
For the first study, apps were selected based on their appearance in popular media articles about dating applications. Results generally related to online safety concerns, while occasional features were related to sexual safety concerns. Communication options were …
Effects Of Nicotine Withdrawal On Motivation, Reward Sensitivity And Reward-Learning, Jason A. Oliver
Effects Of Nicotine Withdrawal On Motivation, Reward Sensitivity And Reward-Learning, Jason A. Oliver
USF Tampa Graduate Theses and Dissertations
Research on addictive behavior has traditionally emphasized the role that primary reinforcing effects of drugs of abuse plays in the development and maintenance of dependence. However, contemporary behavioral economic theory and animal models of nicotine dependence suggest the need for greater attention to the impact that response to alternative rewards may have on smoking behavior. The present study sought to investigate the impact of nicotine withdrawal on self-report, behavioral and neural indices of motivation, immediate response to rewards and the capacity to learn and modify behavior in response to positive and negative feedback. Heavy smokers (n = 48) completed two …
Undergraduate College Students’ Attitudes About Internet-Based Mental Health Interventions, Kathleen Palmer
Undergraduate College Students’ Attitudes About Internet-Based Mental Health Interventions, Kathleen Palmer
USF Tampa Graduate Theses and Dissertations
Millennial-aged young adults, often referred to as “digital natives,” comprise the typical college-age population, and there has been a growing number college students at risk for mental health problems (Mowbray, Mandiberg, Stein, Kopels, Curlin, Megivern, Strauss, Collins & Lett, 2006; Eisenberg, Gollust, Golberstein & Hefner, 2007). Suicide is the second leading cause of death among college students (Suicide Statistics, 2014); however, their rate of utilizing mental heath counseling is decreasing. Providing the types of mental health services college students are likely to use can mitigate factors thought to impede their use (e.g., stigma, anonymity, confidentiality), as well as help improve …
Nearest Neighbor Foreign Exchange Rate Forecasting With Mahalanobis Distance, Vindya Kumari Pathirana
Nearest Neighbor Foreign Exchange Rate Forecasting With Mahalanobis Distance, Vindya Kumari Pathirana
USF Tampa Graduate Theses and Dissertations
Foreign exchange (FX) rate forecasting has been a challenging area of study in the past. Various linear and nonlinear methods have been used to forecast FX rates. As the currency data are nonlinear and highly correlated, forecasting through nonlinear dynamical systems is becoming more relevant. The nearest neighbor (NN) algorithm is one of the most commonly used nonlinear pattern recognition and forecasting methods that outperforms the available linear forecasting methods for the high frequency foreign exchange data. The basic idea behind the NN is to capture the local behavior of the data by selecting the instances having similar dynamic behavior. …
Feeling At Home With Grief: An Ethnography Of Continuing Bonds And Re-Membering The Deceased, Blake Paxton
Feeling At Home With Grief: An Ethnography Of Continuing Bonds And Re-Membering The Deceased, Blake Paxton
USF Tampa Graduate Theses and Dissertations
Bereavement scholars Silverman, Nickman, and Klass (1996) have argued that rituals to continue a relationship with the deceased do not have to be considered pathological in nature. Since their work, scholars have offered specific strategies for the bereaved to actively construct a bond after death, including telling stories about those who have died, having imagined conversations with the deceased, celebrating their birthdays and anniversaries, and reviewing artifacts that represent or once belonged to them (among other strategies). Hedtke and Winslade (2004) call these “re-membering” processes by which the deceased can regain active membership in their loved ones lives. This dissertation …
Modeling Intrusive Geometries Of A Shallow Crustal Intrusion: New Evidence From Mount Ellsworth, Utah, Nathan Nushart
Modeling Intrusive Geometries Of A Shallow Crustal Intrusion: New Evidence From Mount Ellsworth, Utah, Nathan Nushart
USF Tampa Graduate Theses and Dissertations
Surface displacements resulting from upper-crustal intrusion of melt are a paramount concern for communities and facilities located in or near active volcanic areas (e.g. Campi Flegrei, Yucca Mtn.). Study of active intrusions such as Campi Flegrei, Italy west of Mt. Vesuvius, is limited to remote observations through geophysical/geodetic procedures. While the surface displacement due to melt emplacement at depth can easily be determined, the geometries and depth of intrusions are often based on simplified assumptions (e.g. spheres and prolate or oblate ellipsoids). These models benefit from data constraining both the geometries of the individual intrusions, and the kinematics and mechanics …
Assessment Of Public Health Risks Associated With Petrochemical Emissions Surrounding An Oil Refinery, Erin L. Pulster
Assessment Of Public Health Risks Associated With Petrochemical Emissions Surrounding An Oil Refinery, Erin L. Pulster
USF Tampa Graduate Theses and Dissertations
Refinery operations have been associated with a wide variety of atmospheric emissions consisting of criteria air pollutants, volatile organic components, hazardous air pollutants as well as other pollutants. With approximately 100 oil refineries in the Wider Caribbean region (WCR), hydrocarbons in this region pose significant environmental and human health risks. One of the oldest and largest refineries in the WCR is the Isla Refineriá, which is located on the island of Curaçao, and has been the basis of historical debates and conflict between the public and the local government over the environmental and human health risks. This research aims to …

USF Tampa Graduate Theses and Dissertations
The purpose of this case study was to better understand the nature of the experiences of a preservice teacher, self-identified as having mathematics anxiety as she planned and implemented instruction during her internship by answering: What is the nature of the experiences of a preservice teacher, self-identified as having mathematics anxiety, as she planned for mathematics instruction during her final internship? What is the nature of the experiences of a preservice teacher, self-identified as having mathematics anxiety, as she implemented mathematics instruction during her final internship? Using an interpretivist approach to a case study inquiry, I used semi-structured interviews, observations, …
History, Current Conditions, And Wetland Restoration At Killin Wetlands Natural Area, Washington County, Oregon, John A. Christy
History, Current Conditions, And Wetland Restoration At Killin Wetlands Natural Area, Washington County, Oregon, John A. Christy
Institute for Natural Resources Publications
In September 2014, the Metro Natural Area Program engaged The Wetland Conservancy to develop a scientific assessment of Metro’s 590-acre Killin Wetlands Natural Area. Metro acquired the lands comprising the KWNA between 2000 and 2012 with funds from two voterapproved open space bond measures. Since 2000, Metro has sought to advance natural area restoration at the site, focusing on the suppression of non-native pasture weeds and planting of native trees and shrubs in higher parts of the floodplain and its edges. Most uplands in Metro ownership have been maintained in agriculture through leased partnerships with local farmers.
Metro and its …
Population Dynamics Of The Little Gulper Shark (Centrophorus Uyato) And Community Analyses Of Elasmobranch Species In The Northern Gulf Of Mexico, Jacquelin Joye Hipes
Population Dynamics Of The Little Gulper Shark (Centrophorus Uyato) And Community Analyses Of Elasmobranch Species In The Northern Gulf Of Mexico, Jacquelin Joye Hipes
USF Tampa Graduate Theses and Dissertations
In chapter 1 I describe the population dynamics of an understudied species of gulper shark, Centrophorus uyato (common name, the Little Gulper), found in the Northern Gulf of Mexico. Sharks in the family Centrophoridae are mid-sized, demersal fish, with seven species identified in North American waters. These deepwater species can be difficult to study due to the extreme depths at which they occur. During four longlining cruises from 2012-2014, 593 sharks were landed, predominantly in the Mississippi Canyon off the Louisiana coast. Mean depth of capture was 290 m. Supplementing these data are catch records for C. uyato from a …
A Multilevel Examination Of Cultural Moderators Of The Job Demands-Resources Model, Seulki Jang
A Multilevel Examination Of Cultural Moderators Of The Job Demands-Resources Model, Seulki Jang
USF Tampa Graduate Theses and Dissertations
Although the Job Demands-Resources Model (JD-R) is the dominant theoretical framework used to understand the relationship between workplace factors and employee well-being, the cross-cultural generalizability of this model has seldom been directly tested. Therefore, this study examined whether and to what extent relationships between: 1) job demands (i.e., organizational constraints) and strain (i.e., job satisfaction, and turnover intentions) and 2) job resources (i.e., job control, participation in decision-making, direct supervisor support, senior leader support, and clear goals and performance feedback) and strain were moderated by cultural dimensions (i.e., individualism-collectivism and uncertainty avoidance). Survey data from workers in 28 countries were …
Comparison Of Gastropod Assemblages From Natural And Phosphate Mine Lakes Of Central Florida, William A. Mailand
Comparison Of Gastropod Assemblages From Natural And Phosphate Mine Lakes Of Central Florida, William A. Mailand
USF Tampa Graduate Theses and Dissertations
Investigations were made examining the relationships between gastropod species richness and abundance across 20 phosphate and 20 natural lakes in Central Florida. In additional to lake category, age of phosphate lakes was used to determine if phosphate lakes ever approximate natural lakes. Additional physical, chemical, and biological parameters, including chlorophyll a, Ca, secchi, phosphorous, conductance, fish predation, and recreational lake use were investigated in order to determine if they affected gastropods with lake age. Comparisons were also made between gastropod species richness and average abundance and two groups of dominant vegetation categories: Panicum, a structurally complex macrophyte, and Typha …
The Characterization Of The Neuropathological Consequences Of Plac1 Ablation In A Mutant Mouse Model, Jacob Robert Bourgeois
The Characterization Of The Neuropathological Consequences Of Plac1 Ablation In A Mutant Mouse Model, Jacob Robert Bourgeois
USF Tampa Graduate Theses and Dissertations
Placenta-specific 1 (Plac1) is an X-linked gene that is essential for normal placental development. Previous studies have shown that Plac1 is also expressed in the fetal brain and paternally imprinted. Its expression in the fetal brain is markedly downregulated immediately after birth. Plac1 ablation predisposes Plac1-null males and Xm-X Hets (inactive maternal allele) to an increased risk of developing lethal postnatal hydrocephalus suggesting a functional role for Plac1 during embryonic development. The objective of this study was to characterize the effect of Plac1 on brain development and postnatal function. In order to address this, a …
2,4-Disubstituted Quinazolines With Antileishmanial Or Antibacterial Activity, Megan Marie Barber
2,4-Disubstituted Quinazolines With Antileishmanial Or Antibacterial Activity, Megan Marie Barber
USF Tampa Graduate Theses and Dissertations
Herein 47 2,4-disubstituted quinazolines were synthesized and tested against Leishmania donovani intracellular amastigotes. A structure-activity relationship was conducted and lead to the identification of quinazolines with EC50s in the single digit and high nanomolar range with favorable antileishmanial selectivity indexes. Quinazoline 2.6 and 2.31 underwent in vivo efficacy studies in murine models of visceral leishmaniasis, reducing liver parasitemia by 12 % and 24 %, respectively, when given by the intraperitoneal route at 15 mg/kg/day x 5 days. The antileishmanial efficacy and easy of synthesis make the 2,4-disubstituted quinazoline compound series a suitable platform for the future development of antileishmanial agents. …
