The War Of The Roses: Ritual Shaming, Morality, And Gender On The Radio, Jill M. Potkalesky

USF Tampa Graduate Theses and Dissertations

In this thesis, I show how a current radio program, War of the Roses, acts as a ritual of shaming that affirms the social order as moral order, involving moral condemnation, degradation of social identity, and public embarrassment (Goffman, 1956, 1967; Turner 1987). I use discourse analysis (DA) (e.g., Bergmann, 1998; Tracy, 2001; Tracy & Mirivel, 2008) and membership categorization analysis (Baker, 2000; Roulston, 2001) to examine eight transcripts from multiple versions of the War of the Roses radio program across the country. The basic premise of the radio program War of Roses involves a "caller" who suspects her or …

An Evolving Dyke-Otomy: Lesbianism And Learning, Megan Pugh

USF Tampa Graduate Theses and Dissertations

Homophobia and prejudice against the lesbian community have been argued to be consequences of lack of education within academic and non-academic spaces. This study introduces a pedagogical model of gendered lesbian identity that can act as a tool for educators to understand lesbian experiences, and thus contribute to addressing issues related to homophobia and prejudices in the classrooms and beyond. Based on thematic analysis of data generated by a qualitative online survey of 29 participants, this study argues that notions of social norms, individual agency, and importance of advocacy are critical points of emphases in the proposed educational model. Although …

Occupational Stressors Among Providers Of Hiv Prevention And Support Services, Mackenzie Kaye Rapp

USF Tampa Graduate Theses and Dissertations

Much literature has documented the high levels of burnout, stress, and grief in HIV physicians and nurses due to the challenging nature of the chronic, fatal disease with which they deal on a daily basis. Providers of social and HIV prevention services face similar challenges while working with stigmatized, terminally ill clients. However, since these latter occupations deal with social, rather than clinical interventions, their experiences may differ from those of medical personnel. Through open-ended interviews with HIV counselors, educators, case managers, and outreach workers, this exploratory study assesses the occupational stressors of providers of social and HIV prevention services …

Structure And Dynamics Of The P53 Transactivation Domain Binding To Mdm2 And Rpa70, Anne Terese Powell

USF Tampa Graduate Theses and Dissertations

The tumor suppressor protein, p53, is mutated or dysregulated in nearly all human cancers(1). The amino terminal domains are essential for transcriptional activation in stressed cells and play a vital role in cell cycle regulation, apoptosis and senescence. The transactivation (TAD) and proline rich domains in this region are dynamic and intrinsically disordered; lacking stable secondary or tertiary structure. This region contains multiple binding sites; arguably, the most significant of these is for p53's negative regulator, the E3 ligase, MDM2. An important, but less understood interaction involving the single stranded DNA binding protein, RPA70A, is hypothesized to be involved in …

Use Of Adventitious Roots For The Determination Of Hydroperiod In Isolated Wetlands, Michael Joseph Reyes

USF Tampa Graduate Theses and Dissertations

Abstract

Accurate measurement of the hydroperiod in isolated wetlands currently relies upon the installation and frequent monitoring of devices such as piezometers and staff gauges. Observations of biological indicators of the hydroperiod may be able to supplement data collected from these devices and could potentially replace them as a means of accurately determining this hydrologic interval. The study objective was to determine whether adventitious root formation and maturation on buttonbush (Cephalanthus occidentalis) could be used as a viable indicator of the hydroperiod in isolated wetlands. Buttonbush seedlings were flooded in a controlled environment over a three month period in the …

Effects Of G-Csf On Monocytes And Neurons: In Vitro And In Vivo Studies In A Mouse Model Of Alzheimer's Disease, Amanda Renee Pennington

USF Tampa Graduate Theses and Dissertations

G-CSF is routinely used to treat neutropenia/leukopenia or to increase hematopoietic stem cell generation in bone marrow donors. G-CSF and its receptor, G-CSFR, are produced by various cell types both in the peripheral circulation and within brain. As a consequence, exogenous administration of G-CSF results in a broad spectrum of effects involving hematopoietic, immune and central nervous systems.

G-CSF administration in a mouse model of Alzheimer's disease (AD) has revealed both cognitive benefits and disease modifying effects: a) decreased Aβ plaque burden, b) increased microgliosis, c) increased neurogenesis and d) improved performance in radial arm water maze (RAWM). In clinical …

Cell Adhesion And Migration On Ndga Cross-Linked Fibrillar Collagen Matrices For Tendon Tissue Engineering, Ana Ysabel Rioja

USF Tampa Graduate Theses and Dissertations

Tendons, essential tissues that connect muscles to bones, are susceptible to rupture/degeneration due to their continuous use for enabling movement. Often surgical intervention is required to repair the tendon; relieving the pain and fixing the limited mobility that occurs from the damage. Unfortunately, post-surgery immobilization techniques required to restore tendon properties frequently lead to scar formation and reduced tendon range of motion. Our ultimate goal is to create an optimal tendon prosthetic that can stabilize the damaged muscle-bone connection and then be remodeled by resident cells from the surrounding tissues over time to ensure long-term function. To achieve this, we …

Macroencapsulation Of Phase Change Materials For Thermal Energy Storage, Swetha Pendyala

USF Tampa Graduate Theses and Dissertations

The use of a latent heat storage system using phase change materials (PCMs) is an effective way of storing thermal energy. Latent heat storage enables high-energy storage density which reduces the footprint of the system and the cost. However, PCMs have very low thermal conductivities making them unsuitable for large-scale use without enhancing the effective thermal conductivity. In order to address, the low thermal conductivity of the PCMs, macroencapsulation of PCMs has been adopted as an effective technique. The macroencapsulation not only provides a self-supporting structure of PCM and separates the PCM from thermal fluids but also enhances the heat …

A Statically Balanced Shape-Shifting Surface, Joseph Eugene Pishnery

USF Tampa Graduate Theses and Dissertations

ABSTRACT

This paper presents a concept for producing a Statically Balanced Shape-Shifting Surface (SB-SSS). In this context, an SB-SSS is a surface that can require near-zero magnitude force changes to accomplish a change in shape while retaining effectiveness as a physical barrier. This paper focuses on how to statically balance a specifically-designed compliant mechanism and how to incorporate this mechanism into a polygonal cell.

The mechanism consists of a compliant Peaucellier-Lipkin linkage layered with a pre-stressed link as the balancer. Previous work is presented that can show how a polygonal cell can be incorporated into a surface via a tiling …

Novel Blends Of Sulfur-Tolerant Water-Gas Shift Catalysts For Biofuel Applications, Timothy Michael Roberge

USF Tampa Graduate Theses and Dissertations

As traditional sources of energy become depleted, significant research interest has gone into conversion of biomass into renewable fuels. Biomass-derived synthesis gas typically contains concentrations of approximately 30 to 600 ppm H2S in stream. H2S is a catalyst poison which adversely affects downstream processing of hydrogen for gas to liquid plants. The water-gas shift reaction is an integral part of converting CO and steam to H2 and CO2. Currently, all known water-gas shift catalysts deactivate in sulfur concentrations typical of biomass-derived synthesis gas. Novel catalysts are needed to remain active in the presence of sulfur concentrations in order to boost …

For Better Or Worse: An Examination Of The Antecedents And Outcomes Of Mentor Commitment In Mentoring Relationships, Laura Poteat

USF Tampa Graduate Theses and Dissertations

This study examined a model of the antecedents and outcomes of mentor commitment to workplace mentoring relationships. The proposed model was based on the investment model of commitment. A total of 180 pairs of mentors and their protégés completed surveys that assessed model constructs. Results indicated that mentor relationship satisfaction and investment size predict mentor commitment, whereas mentor quality of alternatives and perceptions of managerial support for mentoring do not predict mentor commitment. Additionally, mentor commitment is associated with information exchange behaviors engaged in by mentors and protégés. These findings suggest that commitment plays an important role in mentoring relationships, …

The Biomechanics Of Tongue Projection In The Frog _Rana Pipiens_: Dynamics And Temperature Effects, Paula Sandusky

USF Tampa Graduate Theses and Dissertations

Ectotherms such as frogs must either function within environments with temperatures amenable to their physiological needs, or find means to reduce the impact of temperature on their activities. Recent studies on reptile and amphibian feeding have shown convergent use of elastic recoil to drive feeding movements, thereby decoupling temperature's effects on muscle from movement and allowing the animals to feed over broader temperature ranges. Rana pipiens specimens (n=5) were exposed to three ambient temperatures (10°, 15°, and 25° C) at which feeding behavior was imaged at 6000 Hz. The image sequences yielded detailed kinematic and dynamic information for jaw, tongue, …

Fit To Lead? Supervisors' Health Behaviors, Well-Being, And Leadership Behaviors, Kristin Saboe

USF Tampa Graduate Theses and Dissertations

This study proposes a model to test the relationships amongst supervisors' health behaviors and leadership behaviors. Specifically, 107 supervisor-subordinate pairs responded to a cross-sectional survey. Supervisors provided self-reports of their health behaviors (physical activity, diet, sleep, alcohol/tobacco use) and perceived well-being. Subordinates rated the supervisors' perceived leadership style and the quality of relationships they share at work. Results were mixed with support largely being found for previously established relationships between (a) physical activity, sleep duration and quality, and well-being, and (b) leadership behaviors and supervisor-subordinate relationship quality. The primary thesis of this study--that leaders with improved health behaviors and well-being …

The Effect Of Mortgage Liberalization On Housing Patterns In Tampa Bay, Jason Richardson

USF Tampa Graduate Theses and Dissertations

This study seeks to determine whether the process of mortgage finance liberalization, manifested in concurrent activities of securitization, deregulation, and neo-liberal policy, have resulted in changes to the tenure of residents in neighborhoods in Tampa Bay. It makes use of existing literature on gentrification and mortgage finance and compares those findings with three sample neighborhoods in and around the city of Tampa. To do so the thesis employs data collected from lenders pursuant to the Home Mortgage Disclosure Act, court records of sales and mortgages filed with the Clerk of the Circuit Court of Hillsborough County, and interviews with stakeholders …

On The Spatial And Temporal Variability Of Upwelling In The Southern Caribbean Sea And Its Influence On The Ecology Of Phytoplankton And Of The Spanish Sardine (Sardinella Aurita), Digna Tibisay Rueda-Roa

USF Tampa Graduate Theses and Dissertations

The Southern Caribbean Sea experiences a strong upwelling process along the coast from about 61°W to 75.5°W and 10-13°N. In this dissertation three aspects of this upwelling system are examined: (A) A mid-year secondary upwelling that was previously observed in the southeastern Caribbean Sea between June-July, when land based stations show a decrease in wind speed. The presence and effects of this upwelling along the whole southern Caribbean upwelling system were evaluated, as well as the relative forcing contribution of alongshore winds (Ekman Transport, ET) and wind-curl (Ekman Pumping, EP). (B) Stronger upwelling occurs in two particular regions, namely the …

Investigation Of Reservoirs Of Fecal Indicator Bacteria And Water Quality On The Presence Of Allochthonous Pathogens And The Ecology And Virulence Of Vibrio Vulnificus, Christopher Staley

USF Tampa Graduate Theses and Dissertations

The quality of recreational and shellfishing waters has historically been monitored using commensal, allochthonous bacteria shed in feces (fecal indicator bacteria, FIB). The fate of FIB in the environment should mimic that of bacterial, protozoan, and viral human pathogens, which may also be allochthonous (e.g. Salmonella, Cryptosporidium, or enteric viruses) or autochthonous (e.g. Vibrio spp.) to aquatic environments. FIB are contributed to water from human and animal sources; however, pollution source cannot be determined by conventional FIB measurements. Because fecal source determination is important for pollution remediation and assessment of human health risks, microbial source tracking (MST) methods are …

Natural And Anthropogenic Influences On The Morphodynamics Of Sandy And Mixed Sand And Gravel Beaches, Tiffany Roberts

USF Tampa Graduate Theses and Dissertations

Beaches and coastal environments are dynamic, constantly shaped and reshaped by natural processes and anthropogenic modifications. The morphodynamics and influence of natural and anthropogenic factors of two different coasts at various temporal and spatial scales are discussed.

To quantify the performance of several beach nourishment projects at annual temporal and kilometer spatial scales on three adjacent microtidal low-wave energy barrier islands in west-central Florida, a total of 5,200 beach and nearshore-profiles spaced at 300 m were surveyed monthly to bi-monthly from 2006-2010. Beach nourishment performance is most significantly influenced by the interruption of longshore sediment transport by complex tidal-inlet processes. …

Autism Spectrum Disorders (Asd): Knowledge, Training, Roles And Responsibilities Of School Psychologists, Stacey Small

USF Tampa Graduate Theses and Dissertations

The number of students with autism spectrum disorders (ASD) has increased over the years and therefore it seems inevitable that school psychologists will encounter these students as part of their roles in assessment, consultation, and/or intervention. There are a multitude of articles and books on the signs and symptoms of ASD, as well as suggestions for assessment and intervention, but there are no published data related to school psychologists' knowledge, training, and roles and responsibilities for students with ASD. Therefore, the current study sought to inform the field of school psychology with respect to these issues. One hundred members of …

Modulating The Pharmacokinetics Of Bioflavonoids, Adam John Smith

USF Tampa Graduate Theses and Dissertations

One of the largest obstacles in drug development is to overcome solubility and bioavailability problems. Preformulation strategies such as nanoparticle formation are often employed but sometimes create new issues and are limited in their effectiveness and applications. Since the majority of drugs are marketed and sold as solid forms, drug delivery systems are not always desirable. This is where solid-state chemistry becomes important. Traditional solid-state chemistry approaches are often successful but are sometimes too restrictive and cannot be applied to certain compounds. Cocrystals have emerged as an alternative solid-state technique that can be applied to a broad range of compounds. …

Musical Rhetoric And Sonic Composing Processes, Kyle D. Stedman

USF Tampa Graduate Theses and Dissertations

This project is a study of musical rhetoric and music composition processes. It asks the questions, "How does the nature of music as sound-in-time affect its rhetorical functions, production, and delivery?" and "How do composers approach the task of communicating with audiences through instrumental music?" I answer these questions by turning to the history of musical rhetoric as practiced in the field of musicology and by interviewing composers themselves about their composition practices--approaches that are both underused in the rhetoric and composition community.

I frame my research participants' responses with a discussion of the different degrees to which composers try …

Emotion-Modulated Startle And The Course Of Major And Minor Depression, April Taylor-Clift

USF Tampa Graduate Theses and Dissertations

Major depressive disorder (MDD) is highly recurrent. Researchers have proposed that certain traits predispose people to repeated episodes of this disorder. The current study examined the hypothesis that maladaptive emotional responding to stimuli would predict a worse depression outcome over six months. Participants were 58 individuals--18 controls, 22 individuals with MDD, and 18 individuals with minor depression (mD; subthreshold depression)--who participated in a diagnostic interview and emotion-modulated startle procedure at time one, and who returned for a second diagnostic interview six months later at time two. An identical emotion-modulated startle procedure was then repeated at time two with 33 individuals--12 …

Sugar Consumption And Cognitive Aging In The Swedish Adoption/Twin Study Of Aging, Shyam Seetharaman

USF Tampa Graduate Theses and Dissertations

Abstract

Consumption of foods high in sugar content has been linked with the development of metabolic abnormalities such as cardiovascular disease and type II diabetes, major sources of global health concerns. Although the detrimental consequences of high intake of sugar on abnormal metabolic processes are established, it is not known how this association affects (or accelerates) cognitive aging.

The current project was based on data from the Swedish Adoption/Twin Study of Aging (SATSA) to test the hypothesis that high refined sugar intake contributes to accelerated trajectories of cognitive decline assessed longitudinally. Trajectories of cognitive change were assessed as a function …

Examining Teacher Identity And Prospective Efficacy Beliefs Among Students Enrolled In A Precollegiate Urban Teaching Academy (Uta), Marsha Simon

USF Tampa Graduate Theses and Dissertations

Teacher recruitment and retention challenges facing urban school contexts provided the impetus for this study. High percentages of historically marginalized students, plagued by high poverty rates and low academic performance, as well as substandard facilities and inadequate material resources, serve as causative factors inhibiting recruitment and retention of credentialed teachers in urban schools (Education Commission of the States [ECS], 1999; Guarino et al., 2006; Horng, 2009; USDOE, 2003; 2004; Wirt et al, 2004). Schools and districts attempt to meet chronic teacher shortages in hard-to-staff urban schools by creating innovative teacher preparation schemes, such as the Urban Teaching Academy (UTA). This …

Analysis And Remediation Of Chlorinated Hydrocarbons In Environmental Media, Jonathan Ticknor

USF Tampa Graduate Theses and Dissertations

The two objectives of this work were to develop a simplified method for the analysis of chlorinated organics in water samples and to improve an existing soil remediation technology. The contaminants considered for these studies were chlorinated hydrocarbons because of their relative frequency of appearance at contaminated sites. The first half of this study involved the analysis of chlorinated ethenes by gas chromatography with flame ionization detection (GC-FID). I tested the hypothesis that the FID response factor is the same for all chlorinated ethene compounds. The rationale for this investigation is that if the hypothesis is correct, a single calibration …

A Dual-Factor Model Of Mental Health In High School Students: Group Characteristics And Social Functioning, Amanda Lynn Thalji

USF Tampa Graduate Theses and Dissertations

A dual-factor model of psychological functioning examines the presence of wellness (i.e., subjective well-being; SWB) and psychopathology (i.e., internalizing and externalizing behavior problems) in explaining youth mental health functioning. Using a dual-factor model, previous research has yielded four unique groups of elementary and middle school youth as well as college-age adults with distinct levels of wellness and psychopathology. The present empirical investigation included valid data from 500 adolescents from two high schools (grades 9 to 11). This exploratory study produced four groups of students with unique mental health profiles aligned with previous studies investigating the dual-factor model. Tukey-Kramer comparisons determined …

Cultivating An Engaged Workforce: The Roles Of Leader Personality, Motivation, And Leadership Style, Amy Marie Taylor

USF Tampa Graduate Theses and Dissertations

This study explored the links between leadership style, leader personality, and motivation to lead, with employee engagement. Transformational leadership, transactional leadership, and abusive supervision styles were examined in relation to levels of employee engagement via a sample of n=195 employees and n=130 managers. Consistent with findings from Christian, Garza, and Slaughter (2011), transformational leadership showed a positive link to employee engagement (r= .38, p< .05). On the opposite end, abusive supervision was negatively related to employee engagement (r= -.27, p< .05). Contingent reward leadership showed a positive link to employee engagement (r= .32, p< .05).

Relationships between personality and leadership style were framed according to the socioanalytic framework (Hogan & Shelton, 1998). This study did not find any significant differences in the relationships between the expected leadership behaviors and the traits …

Statistical Estimation Of Physiologically-Based Pharmacokinetic Models: Identifiability, Variation, And Uncertainty With An Illustration Of Chronic Exposure To Dioxin And Dioxin-Like-Compounds., Zachary John Thompson

USF Tampa Graduate Theses and Dissertations

Assessment of human exposure to environmental chemicals is inherently subject to uncertainty and variability. There are data gaps concerning the inventory, source, duration, and intensity of exposure

as well as knowledge gaps regarding pharmacokinetics in general. These gaps result in uncertainties in exposure assessment.

The uncertainties compound further with variabilities due to population variations regarding stage of life, life style, and susceptibility,

etc. Use of physiologically-based pharmacokinetic (PBPK) models promises to reduce the uncertainties and enhance extrapolation between species, between routes, from high to low dose, and from acute to chronic exposure. However, fitting PBPK models is challenging because of …

Monstrous Dialogues: The Host And South Korean Inverted Exile, James Lloyd Turner

USF Tampa Graduate Theses and Dissertations

Bong Joon-ho‟s monster movie blockbuster, The Host (Gweomul, 2006), is the most commercially successful film in South Korean cinema history. The film‟s popularity and significance derive from its unearthing of the ambivalence concerning South Korea‟s rapid transformation from a rural dictatorship to an urban democracy with one of the strongest economies on the planet. This ambivalence is buried beneath a veneer of "progress" blanketing contemporary South Korea and constitutes a condition I call inverted exile. The Host explicitly engages life in inverted exile through my notion of aesthetic dialogue. Aesthetic dialogue, takes influence from the work of Mikhail Bakhtin and …

Quality Of Life In Adult Obsessive-Compulsive Disorder: The Role Of Moderating And Mediating Variables, Brittany Belle Speisman

USF Tampa Graduate Theses and Dissertations

Background: This study examined the contribution of various aspects of obsessive-compulsive disorder (OCD) on quality of life (QoL) in 102 adults with a principal diagnosis of OCD from an archival database. Method: Participants were assessed for DSM-IV diagnoses by trained clinicians using the Anxiety Disorders Interview Schedule, 4th Edition (ADIS-IV), the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), and an unstructured interview. Further information was attained using the Beck Depression Inventory II (BDI-II), the Obsessive Compulsive Inventory Revised (OCI-R) and the Medical Outcome Study-36 (MOS-36). Results: Results indicated that obsessive-compulsive symptom severity was positively correlated with diminished emotional health, social …

Love And Risk: Intimate Relationships Among Female Sex Workers Who Inject Drugs And Their Non-Commercial Partners In Tijuana, Mexico, Jennifer L. Syvertsen

USF Tampa Graduate Theses and Dissertations

This dissertation examines the influence of love and other emotions on sexual and drug-related HIV risk among female sex workers who inject drugs and their intimate, non-commercial partners in Tijuana, Mexico. My work on a public health study along the Mexico-U.S. border and independent ethnographic research in Tijuana suggests the importance of emotions in shaping sex workers' relationships and health risks.

Love is a universal human emotional experience embodied within broader cultural, social, and economic contexts. A growing body of cross-cultural research suggests that modern relationships have transformed to emphasize love and emotional intimacy over moral or kinship obligations. Particularly …
