Relational Agency, Networked Technology, And The Social Media Aftermath Of The Boston Marathon Bombing, Megan M. Mcintyre

USF Tampa Graduate Theses and Dissertations

Agency is a foundational and ongoing concern for the field of Rhetoric and Composition. Long thought to be a product and possession of human action, rhetorical agency represents the most obvious connection between the educational and theoretical work of the field and the civic project of liberal arts and humanities education. Existing theories of anthropocentric rhetorical agency are insufficient, however, to account for the complex technological work of digitally enmeshed networks of humans and nonhumans. To better account for these complex networks, this project argues for the introduction of new materialist theories of distributed agency into conversations about agency within …

Effect Of Dosage Of Non-Chloride Accelerator Versus Chloride Accelerator On The Cracking Potential Of Concrete Repair Slabs, Thomas F. Meagher

USF Tampa Graduate Theses and Dissertations

Due to strict placement time and strength constraints during the construction of concrete pavement repair slabs, accelerators must be incorporated into the mixture design. Since the most common accelerator, calcium chloride, promotes corrosion of concrete reinforcement, a calcium nitrate-based accelerator was studied as an alternative. To replicate mixtures used in the field, commercial accelerators commonly used in concrete pavement repair slabs were used in the current study. Crack risk of different mixtures was assessed using modeling and cracking frame testing. HIPERPAV modeling was conducted using several measured mixture properties; namely, concrete mechanical properties, strength-based and heat of hydration-based activation energies, …

Additives For Heat Transfer Enhancement In High Temperature Thermal Energy Storage Media: Selection And Characterization, Philip D. Myers Jr.

USF Tampa Graduate Theses and Dissertations

Inorganic salts are very promising as high-temperature heat transfer fluids and thermal storage media in solar thermal power production. The dual-tank molten salt storage system, for example, has been demonstrated to be effective for continuous operation in solar power tower plants. In this particular storage regime, however, much of the thermal storage potential of the salts is ignored. Most inorganic salts are characterized by high heats of fusion, so their use as phase-change materials (PCMs) allows for substantially higher energy storage density than their use as sensible heat storage alone. For instance, use of molten sodium-potassium eutectic salt over a …

Theoretical Investigations Of Gas Sorption And Separation In Metal-Organic Materials, Tony Pham

USF Tampa Graduate Theses and Dissertations

Metal--organic frameworks (MOFs) are porous crystalline materials that are synthesized from rigid organic ligands and metal-containing clusters. They are highly tunable as a number of different structures can be made by simply changing the organic ligand and/or metal ion. MOFs are a promising class of materials for many energy-related applications, including H₂ storage and CO₂ capture and sequestration. Computational studies can provide insights into MOFs and the mechanism of gas sorption and separation. Theoretical studies on existing MOFs are performed to determine what structural characteristics leads to favorable gas sorption mechanisms. The results from these studies can provide …

Genetic Moderation Of Phenotypic And Neural Indicators Of Peer Influenced Risk-Taking Behavior: An Experimental Investigation, Troy Alan Webber

USF Tampa Graduate Theses and Dissertations

Risk-taking behavior (RTB) is defined as behavior involving the probability of reward with concurrent probability of some negative outcome. Peer influence is among the most robust predictors of RTB, such that greater peer influence, particularly deviant or delinquent peer influence, is associated with increased RTB. Evidence suggests that those with genetic predispositions for RTB may also be more susceptible to peer influence as a function of genotype. Given that genetic polymorphisms within the dopaminergic system have evidenced associations with various forms of RTB and delinquent peer affiliation, it is possible that these genes may interact with peer influence to predict …

Residency Education In Preparing Adolescent And Young Adults For Transition To Adult Care: A Mixed Methods Pilot Study, Janet S. Hess

USF Tampa Graduate Theses and Dissertations

Background: There is considerable evidence that physicians lack sufficient training in facilitating transition from pediatric to adult care systems for adolescents and young adults (A/YA). While several primary care residency programs have introduced health care transition (HCT) curricula in recent years, there are few studies that assess the effectiveness of HCT teaching models.

Purpose: To assess the impact of a residency education program that uses electronic health records (EHR) and other methods to teach residents how to prepare A/YA for transition to adult care.

Methods: In a mixed methods, quasi-experimental research design, quantitative methods were used to measure change in …

A Study Of Pragmatic Competence: International Medical Graduates' And Patients' Negotiation Of The Treatment Phase Of Medical Encounters, Amy Fioramonte

USF Tampa Graduate Theses and Dissertations

Despite advances in medical technologies, interpersonal communication remains the primary tool physicians use to exchange information, make diagnoses, and treat patients (Cameron & Williams, 1997; Groopman, 2007; Ong, de Haes, Hoos, & Lammes, 1995). In the medical encounter effective communication between physician and patient is essential so that beneficial health and wellbeing outcomes are achieved for patients. Taking a discourse analytic approach, this study examined interactions occurring between international medical graduate (IMG) residents, attending physicians, and patients during the treatment advice phase of the supervised medical encounter. The aim of the study was to examine the co-constructed nature of the …

The Effects Of Collaborative Critical Thinking Training On Trust Development And Effectiveness In Virtual Teams, Mark Grichanik

USF Tampa Graduate Theses and Dissertations

Workers in modern teams that perform tasks over computer-mediated communication channels encounter challenges in building trust and performing effectively. Finding interventions to mitigate such losses could improve team performance. Collaborative critical thinking (CCT) training has the potential to improve trust, monitoring, and effectiveness in virtual teams. Using a simulated search-and-rescue task, the effects of CCT training, as compared with a control training, were evaluated in 105 three-member teams. No effects of CCT training were found on team positive or negative monitoring, team cognitive or affective trust, team efficacy, or team viability. However, teams trained in CCT reported consistently higher levels …

Word Recognition In Noise Among Young And Older Listeners: A Combined Behavioral And Electrophysiological Study, Victoria Ann Williams-Sanchez

USF Tampa Graduate Theses and Dissertations

Word recognition is based on the complex interplay of bottom up processing of acoustic input and corresponding top-down processing based on linguistic redundancies (i.e., contextual cues). Friedrich and Kotz (2007) investigated the timeline of integrating top-down and bottom-up processes among young adults with normal hearing using sentences presented in quiet. As a follow-up study, also with young adults with normal hearing (Experiment 1 of this dissertation), we used sentences embedded in multi-talker background noise and found similar results to Friedrich and Kotz (2007); but, with the use of principal component analysis (PCA) unveiled additional effects of phonological and semantic integration …

Responsibility And Responsiveness In The Novels Of Ann Radcliffe And Mary Shelley, Katherine Marie Mcgee

USF Tampa Graduate Theses and Dissertations

This dissertation looks at the ways in which humans interact with and respond to other humans and nonhumans in Ann Radcliffe's and Mary Shelley's novels. I argue that in light of the social and political turmoil surrounding the French Revolution, Radcliffe and Shelley call not so much for Revolution or drastic reform but for a change in the ways in which individuals respond to the needs of others, both human and nonhuman, and take responsibility for each other. The ways in which humans interact with the nonhuman inform the positive and negative practices that they should use to interact with …

Decolonizing Shakespeare: Race, Gender, And Colonialism In Three Adaptations Of Three Plays By William Shakespeare, Angela Eward-Mangione

USF Tampa Graduate Theses and Dissertations

What role did identification play in the motives, processes, and products of select post-colonial authors who "wrote back" to William Shakespeare and colonialism? How did post-colonial counter-discursive metatheatre function to make select post-colonial adaptations creative and critical texts? In answer to these questions, this dissertation proposes that counter-discursive metatheatre resituates post-colonial plays as criticism of Shakespeare's plays. As particular post-colonial authors identify with marginalized Shakespearean characters and aim to amplify their conflicts from the perspective of a dominated culture, they interpret themes of race, gender, and colonialism in Othello (1604), Antony and Cleopatra (1608), and The Tempest (1611) as explicit …

Top-Down Processes In Simulated Combined Electric-Acoustic Hearing: The Effect Of Context And The Role Of Low-Frequency Cues In The Perception Of Temporally Interrupted Speech, Soo Hee Oh

USF Tampa Graduate Theses and Dissertations

In recent years, the number of unilateral cochlear implant (CI) users with functional residual-hearing has increased and bimodal hearing has become more prevalent. According to the multi-source speech perception model, both bottom-up and top-down processes are important components of speech perception in bimodal hearing. Additionally, these two components are thought to interact with each other to different degrees depending on the nature of the speech materials and the quality of the bottom-up cues. Previous studies have documented the benefits of bimodal hearing as compared with a CI alone, but most of them have focused on the importance of bottom-up, low-frequency …

Knowledge And Acceptance Of Hpv And The Hpv Vaccine In Young Men And Their Intention To Be Vaccinated, Brenda Renee Jasper

USF Tampa Graduate Theses and Dissertations

Sexually active young men are at high risk of contracting HPV and developing genital warts and penile/anal cancers. They contribute significantly to the incidence of HPV in women. The HPV vaccine, Gardasil, was approved in 2009 for use in preventing HPV 6 and 11 in young males ages 9 to 26. Knowledge and awareness of the virus and the vaccine is limited among young men. Promoting education and prevention measures regarding HPV and reducing personal risks to HPV is significant in narrowing the gap between acquisition of the HPV virus and cancer sequelae. A correlational design utilizing cross-sectional survey methodology …

The present study examined the direction and strength of the relation between three different areas academic achievement and working memory with adolescent students. The data analyzed included ratings for inattention, a diagnosis of ADHD (or not), and demographic information for race/ethnicity. Fifty children aged 11 to16 years of age participated in the study. Participants were recruited from several middle schools, homeschooling networks, and churches from a southeastern state of the United States. Each participant completed a standardized achievement test, a behavioral rating scale, and visual and verbal working memory tests. The research questions investigated: 1) the relation between visual and …

"Choosing My Words Carefully": Observing, Debriefing, And Coaching Four Literacy Teachers' Through Their Lessons, Iveta Maska

USF Tampa Graduate Theses and Dissertations

A safe environment, conducive to productive and transparent conversations, makes possible the improvement of literacy practices and strengthens teacher/administrator relationships for more honest and vulnerable conversations. In this autoethnographic intrinsic case study I conducted a self-study of my use of language and communication with four literacy teachers during debrief, after classroom walkthroughs, when coaching each on literacy practice. Furthermore, the component under investigation was the debrief meeting where dialogue is the key ingredient for discussing teacher classroom practice. The study was approached through identifying characteristics from my personal and professional background, to my interactions with the four literacy teachers and …

Social-Emotional Strengths And Academic Outcomes In Kindergarten Students, Bryan B. Bander

USF Tampa Graduate Theses and Dissertations

Social-emotional competence has received increased attention as being critical to a student's success in the classroom. Social-emotional strengths are multidimensional and include assets such as social competence, self-regulation, empathy, and responsibility; however, previous research has not investigated which of these strengths contribute most to a student's academic success. Additionally, limited research has investigated the use of multiple informants (e.g., parents and teachers) to determine whose perceptions are more predictive of academic achievement in kindergarten students. This study examined the relationship between social-emotional strengths, as rated by parents and teachers on the SEARS (Merrell, 2011), and academic outcomes, using the AIMSweb …

Enlightenment On The Margins: The Catholic Enlightenment As Reflected In Ludovico Antonio Muratori's Il Cristianesimo Felice Nelle Missioni De' Padri Della Compagnia Di Gesù Nel Paraguai, Joshua Edward Britt

USF Tampa Graduate Theses and Dissertations

My research analyzes the way in which Ludovico Antonio Muratori portrayed marginal peoples of the New World in his Il Cristianesimo Felice nelle Missioni De' Padri della Compagnia di Gesù nel Paraguai, published in 1743. I argue that Muratori used his portrayal of the native people of Paraguay as a means to express his ideas of how to reform the Catholic Church, at a time when Catholicism was just experiencing the first waves of enlightened influence from the north. I engage with scholarship on the Enlightenment that has addressed specifically the cultural impact of what has been called the Catholic …

The Physiological Effects Of Precooling Beverage Temperatures On Heat Strain In Collegiate Women Soccer Players, Taylor Welch

USF Tampa Graduate Theses and Dissertations

Precooling is a method used to decrease initial pre-exercise core temperature in order to facilitate a greater margin for heat production before a maximum core temperature is reached. The purpose of this study was to examine the differences in physiological and perceptual effects of precooling using beverages of three different temperatures: room temperature beverage (24.88 ± 1.13°C), cold beverage (6.15 ± 3.16°C) and ice slushy (-1.61 ± 0.45°C) in a hot environment (27.88 ± 0.72°C and 35.36 ± 0.83°C for wet globe bulb temperature and dry bulb temperature respectively). For all trials the environmental temperature was set to 35°C with …

A Forgotten Community: Archaeological Documentation Of Old St. Joseph, Gulf County, Florida, Christopher N. Hunt

USF Tampa Graduate Theses and Dissertations

The town of St. Joseph, established in 1835, served as an important deep-water port for receiving and shipping dry goods up the Apalachicola River north along the vast network of navigable inland waterways in southeastern U.S. during the early nineteenth century. Unfortunately, this town was hit with a yellow fever epidemic and a series of hurricanes that, combined with the infancy of its cotton trade activities, eventually devastated its economy and population. The town disappeared by 1842, only much later to be replaced by modern Port St. Joe (est. 1909), located north of the original settlement. However, St. Joseph's influence …

Risk Factors For Recurrent Major Depressive Disorder In A Nationally Representative Sample, Graig Charles Defeo

USF Tampa Graduate Theses and Dissertations

The public use version of the National Comorbidity Survey - Replication (NCS-R) dataset was used (N = 995) to investigate risk factors for recurrent major depressive disorder (MDD) that are evident before recovery from the first major depressive episode (MDE) by comparing persons diagnosed with MDD who experienced a single MDE to persons with recurrent MDD.

Multiple logistic regression analyses assessed the independent risk of recurrent MDD for each of the following risk factors: an early age of onset (old), absence of a life stress trigger, chronic first episode, childhood parental loss, parental maltreatment, parental depression, comorbid anxiety disorder, and …

Polycyclic Aromatic Hydrocarbon Metabolites As A Biomarker Of Exposure To Oil In Demersal Fishes Following The Deepwater Horizon Blowout, Susan Susan Snyder

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout occurred on April 20th, 2010, releasing 4.9 million barrels of Louisiana crude oil into the Gulf of Mexico (GoM). Subsequent to the Deepwater Horizon blowout, sediment cores revealed oil on the northern GoM seafloor and abnormal skin lesions were seen in GoM fishes. Exposure to polycyclic aromatic hydrocarbons (PAHs), a component of crude oil, in fish has been associated with many sublethal effects, including cancer and population-level effects. Using a biomarker of exposure to PAHs, this thesis evaluates inter-species, temporal and spatial differences in exposure to hydrocarbon contamination between three species of fish with varying levels …

Relating Relations: The Impact Of Equivalence-Equivalence Training On Analogical Reasoning, Anna Rosio Garcia

USF Tampa Graduate Theses and Dissertations

A well-researched line showing equivalence performances in a wide variety of areas has been conducted in the field of Behavior Analysis (BA). One area demonstrates that relating relations is a behavioral account of analogical thinking. Relating relations may have implications for the development of analogical training given that analogical reasoning is seen as the foundation of intelligence yet research in this area is limited. A protocol by Stewart, Barnes-Holmes, and Weil (2009) was developed to train children in analogical reasoning using equivalence-equivalence relations. The purpose of this study was to evaluate an equivalence-equivalence training protocol based on Stewart et al. …

Twenty-Five Years Of Giving: Using A National Data Set To Examine Private Support For Higher Education, Karen Ann Frank

USF Tampa Graduate Theses and Dissertations

Resource dependencies have increased substantially at colleges and universities over the years due to economic declines, recessionary periods, and decreased funding from state allocations. The purpose of this study was to advance an understanding of private support for higher education as a source of supplementary funding. As the environment continues to become more competitive for outside resources, institutions of higher education can benefit from more substantive and objective research on private voluntary support to better meet their growing needs for additional resources.

Effective financial management requires a greater understanding of the expected size of financial contributions to assist with strategic …

Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry

USF Tampa Graduate Theses and Dissertations

According the linguistic relativity hypothesis, the language one speaks affects how one thinks. Because languages differ in how they categorize color, linguistic relativity has often been tested by conducting experiments on color perception and memory. This study examines the linguistic relativity hypothesis using ecologically valid stimuli: pictures of eyes. Because Russian-speakers are more likely to describe blue/grey eyes as grey, whereas English speakers are more likely to describe them as blue, English and Russian participants were asked to match the overall color of blue eyes to a color scale. There were three conditions. In the first condition (perception), participants saw …

Medicaid Pays For That? An Exploratory, Mixed-Methods Analysis Of Florida Home Birth, Nicole K. Demetriou

USF Tampa Graduate Theses and Dissertations

The overwhelming social norm for pregnant women in the U.S. is to receive prenatal care from an obstetrician and to give birth in a hospital setting. However, the incidence of midwifery care and out-of-hospital birth is increasing, particularly among White, non-Hispanic women. Florida has been considered a "model" state for home birth midwifery given legislative support that mandates coverage of all types of midwifery (e.g., Certified Professional Midwives and Certified Nurse-Midwives) care in all birth settings (e.g., hospital, home, birth center) and by all forms of insurance (e.g., commercial and Medicaid). Medicaid is the payer source for nearly half of …

Age And Gender Recognition For Speech Applications Based On Support Vector Machines, Hasan Erokyar

USF Tampa Graduate Theses and Dissertations

Automatic age and gender recognition for speech applications is very important for a number of reasons. One of the reasons is that it can improve human-machine interaction. For example, the advertisements can be specialized based on the age and the gender of the person on the phone. It also can help identify suspects in criminal cases or at least it can minimize the number of suspects. Some other uses of this system can be applied for adaptation of waiting queue music where a different type of music can be played according to the person's age and gender. And also using …

Creating A Mythopoeic Graphic Novel To Expand Self-Understanding, Luis De La Lama

USF Tampa Graduate Theses and Dissertations

This is a study about how I produced a graphic novel to introduce a model of the self that is informed by complexity theory to an audience of comic book and graphic novel enthusiasts. Because this model of the self has the potential to preserve, extend, and/or reinforce character strengths that are operationalized as virtuous behavior, and that also function as inner resources in times of adversity, my study explores storytelling by sequential art as a communication method that some counselors and educators might use to counsel and educate large segments of popular culture. Also, more generally, I explore the …

Genres Of Children's Websites: A Comprehensive Methodology For Analyzing Digital Texts, James L. Welsh

USF Tampa Graduate Theses and Dissertations

This study establishes a comprehensive methodology for analyzing children's website content, based on both linguistic and rhetorical data, by employing defensible criteria to evaluate both qualitative and quantitative data. By employing genre theory as a prism for examining form, substance, and rhetorical action within children's websites, this study applies that methodology to a purposeful sample of five children's websites. Results of the analysis document the complex multimodal and multilinear nature of the websites studied and identify a possible new genre, the pop culture carousel website.
