The PTS consists of a graphical user interface (GUI) and a 3D visualization of …

A Cross-Methodological Investigation Of Emotional Reactivity In Major Depression, Vanessa Panaite

USF Tampa Graduate Theses and Dissertations

Major depressive disorder (MDD) is primarily characterized by prevalent sadness and anhedonia. Laboratory studies find that depression is characterized by reduced reactivity across emotional contexts, while a few studies using naturalistic designs find that depressed people show normative reactivity to negative life events and mood brightening in response to positive events. The current study was an investigation of emotional reactivity in depression through the use of experimental and naturalistic designs. This allowed for an investigation of sources of lab-life discrepancies in emotional functioning in depression, including negative affect (NA) regulation. We examined experiential reactivity across contexts and types of stimuli …

A New Materialist Approach To Visual Rhetoric In Photoshopbattles, Jonathan Paul Ray

USF Tampa Graduate Theses and Dissertations

The purpose of this project is to examine the visual rhetoric of one online community. Drawing heavily from the work of Laurie Gries (2015), I track the evolution of an image as it circulates through a forum of photo manipulators in the group “PhotoShopBattles.” While Gries’ work traced the evolution of the iconic Obama Hope poster and its iterations in various media, this project restricts its observations to the images posted to one webpage, focusing on one evolutionary chain. By narrowing the focus to one internet forum page that evolved over the course of one week, we can observe linear …

Inquiry Of Lipid Membranes Interacting With Functional Peptides And Polyphenol Drug Molecules, Chian Sing Ho

USF Tampa Graduate Theses and Dissertations

Cellular membranes are important targets for many membrane-active peptides and drug compounds. Here we are interested in deciphering how lipid membranes are perturbed by several membrane-active molecules, including the transmembrane domain of the influenza M2 protein (M2TM), aggregates formed by a synthetic polyglutamine peptide, and three polyphenol compounds (i.e., tamoxifen, genistein, and verapamil). We employ phase-separated ternary lipid model membranes in the form of giant unilamellar vesicles (GUVs) to simulate raft-like structures that have been proposed to govern many important processes in plasma membranes (e.g., intracellular singling and trafficking). Specifically, we use fluorescent microscopy to interrogate how those membrane additives …

A Power Conflict Approach To Animal Cruelty: Examining How Economic Power Influences The Creation Of Animal Cruelty Laws, Leonard J. Genco

USF Tampa Graduate Theses and Dissertations

The current study examines the association of macro-level economic factors and the creation or enactment animal cruelty laws across the states at a fixed time. Criminologists have postulated that economic factors influence the legal system (Chambliss and Seidman, 1971). This thesis addresses whether state-level economic and related macro-level factors influences the amount and types of state animal cruelty legislation lawmakers enact. To do so, this thesis examined animal cruelty legislation and their association with measures of agricultural and farm production, Democratic Party, Republican Party, and pro-animal interest groups across all states of the United States for the time period (2012-2013). …

Optimizing Methods For Extraction Of Organic Compounds From Molluscan Shells, Kaydee Jo West

USF Tampa Graduate Theses and Dissertations

Mollusk shells contain proteins within and between the crystals of calcium carbonate. These organic molecules play an important role in biomineralization and shell function, and their stable isotope ratios of carbon and nitrogen are also thought to record important ecological information about the animal's diet and nutrient sources. These proteins can be preserved for millions of years, offering potential insight into pre-anthropogenic ecological conditions. However, shell organics in older shells are typically recovered in reduced abundances due to leaching and remaining organics are often converted from insoluble proteins to soluble, free amino acids, making them difficult to detect and recover. …

The Effects Of Age And Gender On Pedestrian Traffic Injuries: A Random Parameters And Latent Class Analysis, Tatok Raharjo Raharjo

USF Tampa Graduate Theses and Dissertations

Pedestrians are vulnerable road users because they do not have any protection while they walk. They are unlike cyclists and motorcyclists who often have at least helmet protection and sometimes additional body protection (in the case of motorcyclists with body-armored jackets and pants). In the US, pedestrian fatalities are increasing and becoming an ever larger proportion of overall roadway fatalities (NHTSA, 2016), thus underscoring the need to study factors that influence pedestrian-injury severity and potentially develop appropriate countermeasures. One of the critical elements in the study of pedestrian-injury severities is to understand how injuries vary across age and gender ‒ …

Urban English Language Arts Teachers’ Stories Of Technology Use: A Narrative Inquiry, Bridget Abbas

USF Tampa Graduate Theses and Dissertations

Technology use in high-minority, low-income middle school ELA classrooms is defined by traditional instructional practices (Applebee & Langer, 2013; Attewell, 2001; Boser, 2013; Cuban, 2001; Lankshear & Knobel, 2008), barriers to access (O’Dwyer et al., 2005; Purcell et al., 2013; Warschauer & Matuchniak, 2010), and inequalities in use (Banister & Reinhart, 2011; Beers, 2004; Gorski, 2009; Makinen, 2006; Powell, 2007; Reinhart et al., 2011; Dijk, 2003, 2006; Warschauer et al., 2004). This characterization, or grand narrative, of technology use is echoed and challenged by this narrative inquiry. Here the stories of two ELA teachers frequently using technology in instruction and …

Subtext Of Decisions: Literacy Practices In The Context Of Coding, Julia Hagge

USF Tampa Graduate Theses and Dissertations

In this dissertation I present findings from a qualitative case study of five early adolescents engaged in an online programming community. As a researcher, I was interested in how early adolescents designed digital media as they learned how to code within an online programming community known as Scratch. My research was guided by two questions: (1) What are the literacy practices and processes embedded in the design and collaboration of products created within an online programming community? (2) In what ways do participants make decisions in the design of their projects created in Scratch? The data collected for …

Development And Validation Of A Remote Sensing Model To Identify Anthropogenic Boreholes That Provide Dry Season, Refuge Habitat For Anopheles Vector Mosquitoes In Sub-Saharan Africa, James Pkemoi Kukat

USF Tampa Graduate Theses and Dissertations

A lack of surveillance systems is an impediment to public health intervention for perennial vector-borne disease transmission in northern tropical savanna region of Kenya. The population in this area are mostly poor nomadic pastoralists with little acquired functional immunity to Plasmodium falciparum, due to infrequent challenges with the parasite. A common characteristic in tropical savanna climatic zone is the availability of riverbeds that have anthropogenic boreholes that provide malaria vector mosquitoes, such as Anopheles gambiae s.l and Anopheles funestus, with aquatic refuge habitats for proliferation and endemic transmission to proximity human households during the dry-season. Unfortunately, currently there …

Inhibiting The Interaction Between Grp94 And Myocilin To Treat Primary Open-Angle Glaucoma, Andrew Stothert

USF Tampa Graduate Theses and Dissertations

Glaucoma is a neurodegenerative protein misfolding disorder classified by increases in IOP, damage to retinal ganglion cells (RGCs), optic nerve (ON) head damage, and progressive irreversible blindness. Primary open-angle glaucoma (POAG) is the most common form of glaucoma, constituting over 90% of clinical cases. POAG is observed in patients where normal outflow channels, mainly the trabecular meshwork (TM), are exposed at the angle formed by the iris and cornea. However, due to TM cellular dysfunction, aqueous outflow resistance is increased preventing normal circulation of aqueous humor. Recent studies have shown that in 2-4% of POAG cases, increased intracellular levels of …

Determining The Effectiveness Of Soil Treatment On Plant Stress Using Smart-Phone Cameras, Anurag Panwar

USF Tampa Graduate Theses and Dissertations

Plants are vital to the health of our biosphere, and effectively sustaining their growth is fundamental to the existence of life on this planet. A critical aspect, which decides the sustainability of plant growth is the quality of soil. All other things being fixed, the quality of soil greatly impacts the plant stress, which in turn impacts overall health. Although plant stress manifests in many ways, one of the clearest indicators are colors of the leaves. In this thesis, we conducted an experimental study in a greenhouse for detecting plant stress caused by nutrient deficienceies in soil using smartphone cameras, …

The Effect Of A Computerized Cognitive-Behavioral Stress Management Intervention On Psychological Factors And Diabetes Management, Cathy A. Bykowski

USF Tampa Graduate Theses and Dissertations

Diabetes is associated with increased psychological distress which, in turn, is associated with poorer diabetes outcomes. This study examined the impact of a nine-week Internet based cognitive-behavioral therapy intervention that targeted stress and mood in people with diabetes. It was hypothesized that the intervention would decrease psychological distress and improve diabetes outcomes and adherence to diabetes treatment regimens. Participants with type 1 and type 2 diabetes were randomly assigned to the intervention (n = 103) or a waiting-list control group (n = 74). ANCOVAs demonstrated significant group effects for the reduction of perceived generalized stress (F (1, 105) = …

Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin

USF Tampa Graduate Theses and Dissertations

Tauopathies are neurodegenerative diseases that affect millions of people around the world. Tauopathies include more than 20 neurodegenerative diseases. Some of the most common tauopathies are Alzheimer’s disease (AD), frontotemporal dementia (FTD), chronic traumatic encephalopathy (CTE), Pick’s disease, corticobasal degeneration, progressive supranuclear palsy (PSP), agyrophillic grain disease, and amyotrophic lateral sclerosis (ALS). These diseases can cause significant memory loss, behavioral changes, motor deficits and speech impairments. Tauopathies stem from accumulation of the microtubule associated protein tau (MAPT). Tau stabilizes microtubules and helps with axonal transport. In a disease state tau becomes hyperphosphorylated and truncated leading to its aggregation. More recently …

Growth, And Development Of Care For Leprosy Sufferers Provided By Religious Institutions From The First Century Ad To The Middle Ages, Philippa Juliet Meek

USF Tampa Graduate Theses and Dissertations

This thesis aims to outline the causes, symptoms, and treatments related to leprosy, and how it can be diagnosed in patients and identified in human remains. The thesis also aims to demonstrate the ways in which care for leprosy sufferers developed as the disease became more prevalent and more commonly, and correctly identified. It analyses the social stigmas inflicted upon sufferers, and the medical care and attention provided for them by religious institutions when other groups or organisations shunned those suffering from leprosy. The rationale for this study is to identify trends surrounding the social stigmas attached to leprosy and …

Beauty, Sex, And Death: The Role Of Mortality Salience In Objectification Processes, Kasey Lynn Morris

USF Tampa Graduate Theses and Dissertations

Although much attention has been paid to the consequences of objectification, relatively little research has focused on the question of why women are objectified. From a terror management theory perspective, the association of women with (literal) objects strips them of the qualities that are threatening (on account of mortality concerns). Sexualization, however, underscores women’s animal nature, and this association is problematic in the management of existential anxiety. The current research builds on a distinction between sexual and appearance-focused objectification to identify the existential mechanisms in the motivation to dehumanize, and subsequently harm, women. Consistent with the hypothesis, participants primed with …

Leukemia Inhibitory Factor As A Neuroprotective Agent Against Focal Cerebral Ischemia, Stephanie Davis

USF Tampa Graduate Theses and Dissertations

Previous publications from this laboratory demonstrated that administration of leukemia inhibitory factor (LIF) (125 µg/kg) to young, male Sprague-Dawley rats at 6, 24, and 48 h after middle cerebral artery occlusion (MCAO) reduced infract volume, improved sensimotor skills, and alleviated damage to white matter at 72 h after the injury. In vitro studies using cultured oligodendrocytes (OLs) showed that LIF (200 ng/ml) also protects against 24 h of oxygen-glucose deprivation through activation of Akt signaling and upregulation of the antioxidant enzymes peroxiredoxin IV and metallothionein III. Other groups have demonstrated that LIF reduces neurodegeneration in animal models of disease, but …

Graduate Student Perceptions Of Multi-Modal Tablet Use In Academic Environments, Ezzard C. Bryant Jr

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to explore graduate student perceptions of use and the ease of use of multi-modal tablets to access electronic course materials, and the perceived differences based on students’ gender, age, college of enrollment, and previous experience.

This study used the Unified Theory of Acceptance and Use of Technology to identify the constructs that may explain a graduate student’s intention to use a multi-modal tablet in graduate course work. This study administered the UTAUT to 224 graduate students from four different colleges at a regional university. The models developed from the UTAUT explained 80% of the …

Cardiovascular Effects Evoked By Airway Nociceptive Reflexes In Healthy And Cardiovascular Diseased Rats, Justin Shane Hooper

USF Tampa Graduate Theses and Dissertations

Acute inhalation of airborne pollutants alters cardiovascular function and has been shown to have its greatest affects on individuals with pre-existing cardiovascular disease. Evidence suggests that pollutant-induced activation of airway sensory nerves via the gating of ion channels is critical to these systemic responses. Here, we have investigated the cardiovascular responses evoked by inhalation of AITC (TRPA1 agonist) and capsaicin (TRPV1 agonist) in healthy Sprague Dawley (SD) and Wistar Kyoto (WKY) rats, and cardiovascular diseased Spontaneously Hypertensive (SH) rats. Inhalation of the agonists by healthy SD and WKY rats caused significant bradycardia, atrio-ventricular (AV) block and prolonged PR-Intervals. Inhalation of …

Writing/Trauma, Natasha Noel Liebig

USF Tampa Graduate Theses and Dissertations

In writing/trauma, I address the association of trauma with knowledge, language, and writing. My discussion first works to establish the relationship between trauma and knowledge. I argue that trauma does not fit into the traditional Enlightenment model of scientific knowledge or the ontological model of what Michele Foucault calls the ‘truth-event.’ Rather, I contend that trauma is unique embodied knowledge, different from that of praxis and normal memory. In general, embodied knowledge is a matter of prenoetic and intentional operations. The body schema and body image maintain a power of plasticity and adjust to new motilities in …

Leibniz's More Fundamental Ontology: From Overshadowed Individuals To Metaphysical Atoms, Marin Lucio Mare

USF Tampa Graduate Theses and Dissertations

I aim to offer an innovative interpretation of Leibniz’s philosophy, first by examining how the various views that make up his ontology of individual substance involve a persistent rejection of atomism in natural philosophy and secondly, by exploring the significance of this rejection in the larger context of Seventeenth-century physics. My thesis is structured as a developmental story, each chapter analyzing the discontinuities or changes Leibniz makes to his views on individuation and atomism from his early to late years. The goal is to illuminate underrepresented views on individuals and atoms throughout Leibniz’s works and thus bring a clearer understanding …

Kant's Just War Theory, Steven Charles Starke

USF Tampa Graduate Theses and Dissertations

The main thesis of my dissertation is that Kant has a just war theory, and it is universal just war theory, not a traditional just war theory.

This is supported by first establishing the history of secular just war theory, specifically through a consideration of the work of Hugo Grotius, Rights of War and Peace. I take his approach, from a natural law perspective, as indicative of the just war theory tradition. I also offer a brief critique of this tradition, suggesting some issues that are endemic to these kinds of theories.

From this general understanding, the version of …

The Statue That Houses The Temple: A Phenomenological Investigation Of Western Embodiment Towards The Making Of Heidegger's Missing Connection With The Greeks, Michael Arvanitopoulos

USF Tampa Graduate Theses and Dissertations

Much of the criticism Heidegger has drawn from realism, from postmodernism and even existentialism, as well from the anti-Nazi protests on his philosophy, could be diluted if a defaulted connection was made between Heidegger's metaphysics and the Greeks. Being and Time drafted the blueprint of the origin of predication and world-disclosure from the primordial intuition of the limitations of action in the face of human finitude. This existential reprioritization forced a radical reversal of primacy from nature to culture, having assumed the absolute objectivity of some original world determinacy, the phenomenological structure of which, nevertheless, was never produced in Heidegger’s …

“It’S Not Pixie Dust”: An Exploratory Qualitative Case Study Of A School-Based Multimodal Tablet Initiative, Erin Elizabeth Margarella

USF Tampa Graduate Theses and Dissertations

This dissertation presents findings from a qualitative case study of three English teachers representing varying levels of comfort with technology and years of teaching experience at St. Patrick Catholic High School. This research was motivated by two questions: (1) What are three literacy educators’ perceptions of a multimodal tablet initiative at a Catholic High School? (2) How is information regarding the use of iPad technology for literacy disseminated to three High School English teachers within a Catholic School system? Data was collected over a twelve-week period during the first academic year of implementation of a school-based multimodal tablet (iPad) initiative. …

The Use Of Synthetic Mixture Based Libraries To Identify Hit Compounds For Eskape Pathogens, Leishmaniasis, And Inhibitors Of Palmitoylation, Marcello Giulianotti

USF Tampa Graduate Theses and Dissertations

The goal of this work is to demonstrate the utility of using systematically formatted mixture based libraries as part of the drug discovery processes. While there are a number of different valid approaches for identifying hit and tool compounds, systematically formatted mixture based libraries, such as those described in this study, offer the ability to develop a significant amount of structure activity relationship data from the testing of very few samples. In support of this claim a review of recent developments in the area of systematically formatted mixture based libraries as well as three case studies are presented. The three …

Cultivating Philanthropy In Community Colleges: A Dual-Model Approach, Rachel Faith Pleasant

USF Tampa Graduate Theses and Dissertations

This study tests a model that combines relationship management theory and the theory of reasoned action. Through the collection of quantitative and qualitative data, this study provides deeper understanding of the relationship between community college students and the institution, and identifies aspects of the relationship that most influence behavioral intention to give to the institution. Using this information, public relations practitioners will be able to strategically improve areas of deficiency in the community college-student relationship, thereby increasing the likelihood that today’s students will become tomorrow’s philanthropic alumni.

The purpose of this study was to explore the self-perception of compassion satisfaction, compassion fatigue, and burnout by student conduct administrators working in the United States of America. Additionally, this study looked at the years of experience, job responsibilities, on-call responsibilities and direct student contact hours which may impact an individual’s overall professional quality of life. To accomplish the objectives outlined in the purpose statement, the following research questions were explored:

1. What is the relationship between student conduct professionals’ compassion satisfaction, burnout, and secondary traumatic stress?

2. What is the relationship between student conduct professionals’ years of experience and …

Vegetative Responses To Hydrology And Ground Water Extraction In West-Central Florida Cypress Domes, Paul Thurman

USF Tampa Graduate Theses and Dissertations

The increasing demand for and limited supply of fresh water necessitates an understanding of how human actions affect aquatic ecosystems. Anthropogenic impacts to these ecosystems occur in many forms including eutrophication, invasive species removals, and hydrologic alterations. Ground water extraction is one such action that can dramatically impact wetland hydrology and is increasing in occurrence globally as clean surface water resources are exhausted. Despite the importance of ground water extraction to meet human demand, little information is available concerning the response of vegetation communities to chronic ground water extraction. Over extraction is known to result in reduced water levels and …

Human Health Risk Characterization Of Petroleum Coke Calcining Facility Emissions, Davinderjit Singh

USF Tampa Graduate Theses and Dissertations

Calcined coke is a high quality carbon material produced by calcining green petroleum coke. Calcining is the process of heating green petroleum coke in a kiln to remove excess moisture, extract all remaining hydrocarbons, and modify the crystalline structure of the coke into a denser, electrically conductive product. The final product, calcined coke, is primarily used to make carbon anodes for the aluminum industry and recarburizing agent for industries such as the steel industry. If not appropriately controlled, the calcining process could lead to excess production of particulate emissions from either handling or storing of raw coke, or from the …

Costumbres, Creencias, Y “Lo Normal”: A Biocultural Study On Changing Prenatal Dietary Practices In A Rural Tourism Community In Costa Rica, Allison Rachel Cantor

USF Tampa Graduate Theses and Dissertations

This study explores the relationship between tourism, the nutrition transition, and prenatal dietary practices in the Monteverde Zone, Costa Rica. This rural tourism community, located in the central highlands of Costa Rica, has seen rapid growth and development since the tourism boom in the early 1990s, leading to changes in the local food system and increased food insecurity. This investigation added to this work by identifying the ways that prenatal dietary practices have shifted over time in the context of increased tourism and the concomitant nutrition transition, and by describing the relationship between food insecurity and nutritional status among pregnant …
