Constructing Health Narratives: Patient Feedback In Online Communities, Katie Lynn Walkup

USF Tampa Graduate Theses and Dissertations

This project examines user-generated health narratives through corpus analysis of 246 reviews posted on Midwestern Hospital’s Yelp page. Understanding how different stakeholders act and interact within online health communities models a shift in new conceptions of health, and provides evidence of health ecologies’ ability to determine patient perceptions of care. Documents produced by users in these health communities represent health narratives comprised of a user’s health experience, that user’s treatment perceptions, and the community’s perceptions of the user’s experience. Author uses corpus methods to interpret user trace data and rhetorical moves embedded in health narratives. Findings suggest that users who …

Get Ye A Copper Kettle: Appalachia, Moonshine, And A Postcolonial World, Christopher David Adkins

USF Tampa Graduate Theses and Dissertations

For little over a century, the American region of Appalachia was an internal mineral colony of the United States. This internal colonization produced innumerable negative environmental and economic effects, as well as – most insidious of all – the constructed stereotype of the Hillbilly that even in the Twenty-First Century refuses to die. Yet part and parcel of that same stereotype is something found all over Appalachia, representing a freedom, an identity, and an heritage so long denied to Appalachia and the Appalachian people on its own terms: moonshine, the colorless, unaged corn whiskey long produced both in Appalachia …

Administrator And Faculty Perceptions Of Institutional Support For Online Education In Florida's College System, Gerene M. Thompson

USF Tampa Graduate Theses and Dissertations

Approximately 30% of Florida’s college system (FCS) students are enrolled in distance learning courses (FLDOE, 2015). As FCS institutions continue to grow their online programs to meet demand, a lack of support from, and consensus among administrator and faculty stakeholders could undermine institutional efforts to sustain growth and quality standards in these programs. The purpose of this quantitative study was to examine administrator and faculty perceptions of institutional support for online education in Florida’s College System. Differences in perceptions between these groups were also investigated. Additionally, this study explored if perceptions differed based on role and level of experience with …

Hydroalkynylation Of Oxocarbenium Intermediates Via Au(I) Catalysis, Courtney Smith Smith

USF Tampa Graduate Theses and Dissertations

Au(I) catalysis has recently emerged as a powerful tool for the realization of a broad range of organic transformations. Despite this rapid development, attaining selectivity and maintaining catalyst stability remain significant challenges. Rational ligand design, such as the employment of NHC or TA ligands, has been used to confront these issues. This thesis focuses on the use of Au(I) catalysts bearing these ligands for the selective hydroalkynylation of enol ethers. By employing a TA-Au stabilized catalyst, [(OAr)₃PAu(TA-H)]OTf, the intermolecular hydroalkynylation of enol ethers, a substrate that is well-known to promote decomposition of the gold cation, was efficiently achieved. …

What Makes Water Policy Sustainable? An Analysis Of Water Policy In Us Cities, Rebecca Brady David

USF Tampa Graduate Theses and Dissertations

This dissertation works to create a clearer understanding of sustainability in water policy. Current water policy in four US cities was compared to a matrix of recommended sustainability themes that have been presented in the literature to determine the extent of which these themes have been implemented into water policy. To best analyze policy for sustainability it is necessary to look at the policy of cities that are considered sustainable. This was determined by a city’s inclusion in “Most Sustainable US Cities” lists. The two cities that best represented sustainability were Austin, TX and San Francisco, CA. The research also …

An Examination Of John Burton’S Method Of Conflict Resolution And Its Applicability To The Israeli-Palestinian Conflict, John Kenneth Steinmeyer

USF Tampa Graduate Theses and Dissertations

This paper argues that the interactive problem-solving workshops created by political scientist John Burton and applied to the Israeli-Palestinian conflict by social psychologist Herbert Kelman, while not, as yet, resulting in a just and permanent peace agreement, are effective in resolving intractable conflict, and, if persistently used, can significantly help to produce such an agreement. This is done by closely examining two books of Burton and a series of articles by Kelman to describe their process; the characteristics of intractable conflict are also reviewed from the work of social psychologist Daniel Bar-Tal. It is then argued that the psychological elements …

Like Watching A Brother Die: Environmental Racism In Bahia, Brazil, Meredith Main

USF Tampa Graduate Theses and Dissertations

Until the 1970s, small black fishing communities primarily populated Bahia’s north coast. A recent demand for luxury coastal real estate has radically altered the region’s social and environmental landscape. While Bahia’s population is roughly 80% poor and black, the coast is now a space of exclusivity and whiteness. Sewage infrastructure does not meet the needs of the growing population. Domestic sewage flows directly into urban rivers. Poor black fishers, whose food security and livelihoods depend on access to healthy water resources, suffer most in this context. This dissertation explores two interlinking forms of environmental racism – water pollution and racial …

The Effects Of Arousal Presented By A Pedagogical Agent On English Language Learners' Situational Interest, Cognitive Load And Reading Comprehension In Online Reading Tasks, Jack Drobisz

USF Tampa Graduate Theses and Dissertations

This research examined how four different animated pedagogical agent implementations, which focus on perceptual and inquiry arousal conditions of attention as defined in Keller’s ARCS model of motivational design (Keller, 2009), impact English language learners' situational interest, cognitive load, and reading comprehension in online readings tasks. Animated pedagogical agents (APA) are computer characters embodied with speech, gestures, or movement (Sweller, Ayres, & Kalyuga, 2011), which according to cognitive-affective theory of learning with media (CATLM; Moreno, 2005; Moreno & Mayer, 2007), can provide a mechanism for triggering situational interest in reading materials through different arousal conditions. In this study, perceptual arousal …

The Apatow Aesthetic: Exploring New Temporalities Of Human Development In 21st Century Network Society, Michael D. Rosen

USF Tampa Graduate Theses and Dissertations

This thesis offers a critical examination of what I call the “Apatow aesthetic” in order to analyze the social processes of growing up in contemporary neoliberal network society. While doctors, psychologists and social scientists still proffer a model of mid- 20th century human development centered around a chronologically-determined life cycle, the Apatow aesthetic imagines a non-linear reality where traditional life events and social practices don’t always correspond to specific age groups. Specifically, I argue, the Apatow aesthetic subjects the spectator to the pleasures and pains of these life-cycle disruptions, and reveals the unfolding of a new cultural shift which challenges …

Nothin' But A Good Time: Hair Metal, Conservatism, And The End Of The Cold War In The 1980s, Chelsea Anne Watts

USF Tampa Graduate Theses and Dissertations

This dissertation offers a cultural history of the 1980s through an examination of one of the decade’s most memorable cultural forms – hair metal. The notion that hair metal musicians, and subsequently their fans, wanted “nothin’ but a good time,” shaped popular perceptions of the genre as shallow, hedonistic, and apolitical. Set against the backdrop of Reagan’s election and the rise of conservatism throughout the decade, hair metal’s transgressive nature embodied in the performers’ apparent obsession with partying and their absolute refusal to adopt the traditional values and trappings of “yuppies” or middle-class Americans, certainly appeared to be a strong …

Longshoremen's Negotiation Of Masculinity And The Middle Class In 1950s Popular Culture, Tomaro I. Taylor

USF Tampa Graduate Theses and Dissertations

This thesis considers mid-20^th century portrayals of working-class longshoremen’s masculinity within the context of emerging middle-class gender constructions. I argue that although popular culture presents a roughly standardized depiction of longshoremen as “manly men,” these portrayals are significantly nuanced to demonstrate the difficulties working-class men faced as they attempted to navigate socio-cultural and socio-economic shifts related to class and the performance of their male gender. Specifically, I consider depictions of longshoremen’s disruptive masculinity, male identity formation, and masculine-male growth as reactions to paradigmatic shifts in American masculinity. Using three aspects of longshoremen’s non-work lives presented in A View from …

Reification, Resistance, And Transformation? The Impact Of Migration And Demographics On Linguistic, Racial, And Ethnic Identity And Equity In Educational Systems: An Applied Approach, Rebecca Ann Campbell

USF Tampa Graduate Theses and Dissertations

Using an applied anthropological approach focused on language, this study investigates the relationship between linguistic, racial, and ethnic identities and school resource access in the context of migration. This project examines how these identities are established, experienced, reified, and resisted by various school actors. Exposing power at its roots through a multi-level analysis, this research informs on how people negotiate socialization into particular identities, propelling them toward positions in school and society of varying opportunity.

Focused on two elementary schools in a central Florida county that has been and is undergoing demographic changes, this work offers applications for educational institutions …

Gene Expression Profiling And The Role Of Hsf1 In Ovarian Cancer In 3d Spheroid Models, Trillitye Paullin

USF Tampa Graduate Theses and Dissertations

Ovarian cancer is the most lethal gynecological cancer, with over 200,000 women diagnosed each year and over half of those cases leading to death. These poor statistics are related to a lack of early symptoms and inadequate screening techniques. This results in the cancer going undetected until later stages when the tumor has metastasized through a process that requires the epithelial to mesenchymal transition (EMT). In lieu of traditional monolayer cell culture, EMT and cancer progression in general is best characterized through the use of 3D spheroid models. In this study, we examine gene expression changes through microarray analysis in …

The Impact Of Criminal Justice Interventions And Social Policies On Family Violence: Theory And Evidence, Sianne Diana Vijay

USF Tampa Graduate Theses and Dissertations

In 2014, the Child Protective Services received 3.6 million referrals alleging child abuse and neglect, of which, 702,000 children were victims of abuse and neglect and an estimated 1,580 children died due to maltreatment. In addition to this appalling toll, the welfare effects of child victimization are substantial. Evidence suggests that compared to demographically similar adults who were non-victims, adults with documented histories of maltreatment are more likely to engage in criminal behavior; have adverse mental and physical health problems such as depression, addiction and post-traumatic stress disorder; and have lower levels of education and earnings. These essays contribute toward …

Hydrolytic And Nonhydrolytic Sol-Gel Zirconia-, Titania-, And Niobia-Based Capillary Microextraction Coatings For The Preconcentration And Hplc Analysis Of Catecholamine Neurotransmitters And Phosphorylated Peptides, Abdullah Awadh Alhendal

USF Tampa Graduate Theses and Dissertations

Sample preparation is the most error-prone step in chemical analysis. A great deal of efforts has been made to develop efficient techniques and protocols for sample preparation to accomplish important goals such as miniaturization and implementation of green analytical methodologies. Solid-phase microextraction (SPME) has successfully eliminated the use of hazardous organic solvents in extraction sampling, sample preparation, preconcentration and sample introduction to the analytical instrument in an effective manner. Ensuring thermal- and solvent-instability of traditional SPME extraction phases represented one of their main drawbacks. This was solved by the introduction of sol-gel SPME phases characterized by enhanced thermal-, solvent-, and …

The Apocalypse Narrative And The Internet: Divided Relationships In New Natures, Brooks Scott Benadum

USF Tampa Graduate Theses and Dissertations

This project proposes that one factor of growing societal interest in the apocalypse narrative is rooted in these stories reflection on our new landscape of telecommunication flows embodied in the Internet. The apocalypse narrative has steadily been growing in popularity, and many academics have offered potential explanations. While other analyses predominately focus on the actual apocalyptic event itself as representative of various societal fears, this project aims to focus on aspects of how we adapt to being in the new apocalyptic landscape, and how this reflects on our own adaptation to being in the new landscape of the Internet. This …

From Portraits To Selfies: Family Photo-Making Rituals, Krystal M. Bresnahan

USF Tampa Graduate Theses and Dissertations

From family-style portraits to selfies, who is photographer and/or photographed varies as families engage, stage, and interpret the visual. How families participate in photo-making changes how individual family members feel about and relate to not only their photographs, but also each other. In this dissertation, I examine photographs as visual and material objects, and include the communication processes and ritual practices of producing, consuming, curating, viewing, and circulating these photos. By framing family photo-making as ritual, I explore how families do photo-making in everyday life, and identify the patterns of choice embedded in the genre of family photography, which symbolically …

Constituting Agricultural And Food Policy In Malawi: The Role Of The State And International Donors In The Farm Input Subsidy Program (Fisp), Peter Rock Nkhoma

USF Tampa Graduate Theses and Dissertations

Numerous studies have been undertaken on the political economy of agricultural policies in developing countries. These studies have explained agricultural policies in terms of urban bias, economic reforms, and domestic politics. Recently, the emphasis has been on explanations that reference the existence of a rational-legal and patronage element within the African state. Such explanations tend to underplay the extent to which agricultural policies are devised in a context of power asymmetries between the state and international donors or financial institutions. In the Malawian context specifically, limited attention has been paid to the possibility that policies are a negotiated outcome of …

Self-Study Of A Supervisor Making Connections In An Integrated Instructional Third Space In Elementary Mathematics And Field Experience, Katie Arndt

USF Tampa Graduate Theses and Dissertations

Too often teachers see mathematics as a culturally neutral subject. Teacher educators need to be aware of their own practice and how it impacts the facilitation of preservice teacher learning, in particular in relation to elementary mathematics and culturally responsive teaching. This qualitative self-study focused on understanding a teacher educator’s enactment of an espoused platform in an integrated instructional third space of an elementary field experience and an elementary mathematics methods course in relation to culturally responsive teaching and mathematics. The research questions guiding this self-study were: (1) In the context of the selfstudy, to what extent do I enact …

Development Of An Anaerobic-Phototrophic Bioreactor System For Wastewater Treatment, Onur Yilmaz Ozcan

USF Tampa Graduate Theses and Dissertations

For decades, mainstream domestic wastewater treatment has relied on activated sludge processes to remove organic matter, and on biological nutrient removal systems like the A²/O process to remove nutrients. Recently, membrane filtration was also added to the realm of possible technologies for domestic wastewater treatment, with aerobic membrane bioreactors (MBRs) becoming increasingly popular, especially for decentralized, and small to medium scale applications. However, the aerobic activated sludge and MBR processes, which are often combined with biological nutrient removal processes, have high energy costs associated with supplying oxygen to the process, and end up converting the organic matter into …

The Role Of Religion In Mitigating Cancer Disparities Among Black Americans, Samar Hennawi

USF Tampa Graduate Theses and Dissertations

The long history of racism has created cultural barriers that prevent some Black Americans from seeking cancer treatment. Fatalism, physician mistrust, low levels of social support and self-efficacy, are the most cited cultural barriers in the literature. Black Americans’ religious beliefs and church involvement have historically helped them in their struggle against racism. A quantitative and a qualitative comparison studies examine the role of Black cancer survivors’ religious beliefs in their fight against cancer. The quantitative comparison study finds no difference in the cultural attitudes between Black and White cancer survivors. However, the qualitative comparison study between the same two …

Currently, there are approximately 1.1 million caregivers who are caring for veterans who have served in the military following September 11 (9/11), 2001 (Ramchand et al., 2014). In this study, a mixed methods analysis of post 9/11 caregivers enrolled in the North Florida South Georgia Caregiver Support Program was completed with a convenience sample of 172 participants for quantitative analysis which included 16 participants for the phenomenological query. Correlations, t-tests, and ANOVAs were used to determine the associations among race, gender, age, caregiver type, diagnosis, tier level, and the presence of children in the home with caregiver burden as measured …

The Influence Of Oxygen Tension And Glycolytic And Citric Acid Cycle Substrates In Acrolein-Induced Cellular Injury In The Differentiated H9c2 Cardiac Cell Model, Jayme Coyle

USF Tampa Graduate Theses and Dissertations

Most in vitro systems employ the standard cell culture maintenance conditions of 95 % air with 5 % CO2 to balance medium pH, which translates to culture oxygen tensions of approximately 20 % - above the typical ≤ 6 % found in most tissues. The current investigation, therefore, aims to characterize the effect of maintenance and toxicant exposure with a particular focus on the α,β-unsaturated aldehyde, acrolein, in the presence of physiologically relevant oxygen tension using a differentiated H9c2 cardiomyoblast subclone. H9c2 cells were maintained separately in 20.1 and 5 % oxygen, after which cells were differentiated for five days, …

The Self-Directed Learning Actions Of Women Regarding The Menopause Transition, Jamie Johnson Cooper

USF Tampa Graduate Theses and Dissertations

Research indicates that increased knowledge about the menopause transition positively impacts a woman’s attitude about this stage in her life, and a more positive attitude leads to less distress during the transition. However, there has been no research regarding how women gain this knowledge about menopause, what factors in her environment may hinder or assist her, or how women’s knowledge of menopause is leveraged by health care providers to help facilitate her menopause transition.

The purpose of this research was to explore the self-directed learning actions of women regarding their search for information about menopause, and to understand what factors, …

Instattack: Instagram And Visual Ad Hominem Political Arguments, Sophia Evangeline Gourgiotis

USF Tampa Graduate Theses and Dissertations

The purpose of this project is to examine the visual political ad hominem arguments used on Instagram during the 2016 presidential campaign. Using Walton’s (2007) five subtypes of ad hominem arguments, this study analyzes the “attack ads” posted on Instagram from five of the 2016 presidential candidates into each subtype. This project seeks to understand how ad hominem arguments within political rhetoric function when they are visual. This study uses Kress and van Leeuwen’s (2006) theory of modality and Rose’s (2012) compositional interpretation to analyze compositional structure of the image and parallels this analysis with ad hominem subtypes.

Findings reveal …
