A Case Study Of Adolescent Females' Perceptions Of Identity In An After-School Book Club, Holly Atkins

USF Tampa Graduate Theses and Dissertations

Reading is a perennial educational hot topic - but now extends for beyond early literacy to the secondary level. Reading researchers are growing in our knowledge of how to reach and teach struggling adolescent readers yet too often success in literacy is measured solely by performance on standardized tests. Literacy is seen on one hand as a one-dimensional set of skills students need to possess to be successful in school and their future workplaces. A more expansive view of the importance of literacy and what it means to adolescent females' growth as individuals and members of communities is needed.

Modeling Of Solar-Powered Single-Effect Absorption Cooling System And Supermarket Refrigeration/Hvac System, Ammar Bahman

USF Tampa Graduate Theses and Dissertations

This thesis consists of two different research problems. In the first one, the aim is to model and simulate a solar-powered, single-effect, absorption refrigeration system using a flat-plate solar collector and LiBr-H₂O mixture as the working fluid. The cooling capacity and the coefficient of performance of the system are analyzed by varying all independent parameters, namely: evaporator pressure, condenser pressure, mass flow rate, LiBr concentration, and inlet generator temperature. The cooling performance of the system is compared with conventional vapor-compression systems for different refrigerants (R-134a, R-32, and R-22). The cooling performance is also assessed for a typical year …

Identification And Characterization Of The Human Herpesviruses 6a And 6b Genome Integration Into Telomeres Of Human Chromosomes During Latency, Jesse Herbert Arbuckle

USF Tampa Graduate Theses and Dissertations

While the latent genome of most Herpesviruses persists as a nuclear circular episome, previous research has suggested that Human Herpesvirus 6 (HHV-6) may integrate into host cell chromosomes, and be vertically transmitted in the germ-line. Because the HHV-6 genome encodes a perfect TTAGGG telomere repeat array at the right end direct repeat (DR_R) and an imperfect TTAGGG repeat at the end of the left end direct repeat (DR_L), we established a hypothesis that during latency, the HHV-6A and HHV-6B genome integrates into the telomeres of human chromosomes through homologous recombination with the n(TTAGGG) viral repeats, and …

The Relationships Between Frontal Alpha Asymmetry, Mood, And Emotional Memory, Ross Avila

USF Tampa Graduate Theses and Dissertations

Frontal alpha asymmetry is often used as a metric to compare activation between homologous frontal brain sites. A positive asymmetry refers to greater activation in the left hemisphere than in the right hemisphere, while the opposite is true of negative asymmetries. Two expansive but largely separate bodies of research have examined the relationships between (1) frontal asymmetry scores and mood, and (2) mood and emotional memory performance. Specifically, one body of research has found that positive moods are associated with positive asymmetries while negative moods are associated with negative asymmetries. A second body of literature has examined the effects of …

Thermal Integrity Profiling Instrumentation Development, Byron Keith Anderson

USF Tampa Graduate Theses and Dissertations

This thesis has shown that the development of the instrumentation necessary to provide in-situ thermal imaging for the determination of homogeneity of concrete is theoretically sound.

Drilled shafts are large diameter underground cast-in-place columns that necessarily rely on sound integrity to properly withstand imposed loadings. As a by-product of the most common construction techniques, the entire process is often completely blind whereby the excavation and concreting processes are conducted beneath the surface of the water table (or slurry level). This results in an inability to inspect the final product and in many cases allows anomalous inclusions (soil cave-ins, slurry pockets, …

Perceptions On Collaborative Learning: A Case Study Of Female Community College Instructors, Marilyn Christine Armstrong

USF Tampa Graduate Theses and Dissertations

In the 1980s, academic assessments called for "the ability of individuals and groups to talk, listen judge, and act on issues of common interest" (Morse, 1989, p. 30). More recently, corporate research findings, Are They Ready to Work? Employers' Perspectives on the Basic Knowledge and Applied Skills of New Entrants to the 21st Century U.S. Workforce (The Conference Board, Inc., Partnership for 21st Century Skills, The Corporate Voices for Working Families, & Society for Human Resource Management, 2006), report the workplace is seeking college graduates with skill in collaboration (e.g. build diverse relationships, negotiate, manage conflict). While the interest in …

The Role Of Discrete Emotions In Predicting Counterproductive Work Behavior, Jeremy Allen Bauer

USF Tampa Graduate Theses and Dissertations

The current study investigates how discrete negative emotions are related to specific facets of counterproductive work behaviors (CWB). The sample consisted of 241 employees who reported their frequency of experiencing negative emotions and their frequency of committing CWBs in the workplace. For 103 employees, supervisor reports of employee CWB were also obtained. The findings provide evidence that a wide range of negative emotions are related to most of the sub facets of CWB. There was also some evidence that supervisor reports differ systematically from employee reports of CWB. The theoretical, methodological, and organizational implications are discussed.

Giving Meaning To Grief: The Role Of Rituals And Stories In Coping With Sudden Family Loss, Julia Janelle Barnhill

USF Tampa Graduate Theses and Dissertations

In this dissertation, I seek to better understand the sensemaking process among surviving family members after a tragic loss of a teenage or young adult child. Using social constructionism (Gergen, 1991) as a theoretical framework, I focused on how meanings of loss are constructed through the use of language and other symbols. I specifically looked at the role of family stories and rituals in making sense of the sudden loss as well as how a survivor's role as a sibling or parent may impact the grieving process. The participants in my research were all members of families in which a …

Synthesis And Characterization Of Self-Healing Poly (Carbonate Urethane) Carbon-Nanotube Composites, Roger Wesley Bass

USF Tampa Graduate Theses and Dissertations

Synthesis of high molar mass polycarbonate polyurethanes using a novel polyol is described. The resulting elastomers demonstrate excellent mechanical properties as well as the capability to re-heal after rupture without the addition of additives or imbedded healing agents. The self-healing functionality is shown to greatly improve with the addition of up to 1% single and multi-walled carbon nanotubes. The interface of the carbon nanotubes and self-healing polymer are probed using Raman techniques and provide an insight into how the self-healing actions are improved with the addition of carbon nanotubes.

Synthesis of polycarbonate polyurethanes and carbon nanotube composites using a novel …

The Natural History Of Human Papillomavirus Related Condyloma In A Multinational Cohort Of Men, Gabriella Anic

USF Tampa Graduate Theses and Dissertations

Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States, but few studies have examined the progression from HPV infection to disease in men. Genital condyloma are the most common clinical manifestation of HPV infection. Though not associated with mortality, condyloma are a source of emotional distress, and treatment is often painful with a high recurrence rate. The aims of this study were to examine the distribution of HPV types present on the surface of condyloma, estimate the incidence of condyloma overall and after type-specific HPV infections, assess the sociodemographic and sexual behavior factors independently associated …

The Virtuoso Human: A Virtue Ethics Model Based On Care, Frederick Joseph Bennett

USF Tampa Graduate Theses and Dissertations

The goal of this thesis is to develop the foundation and structure for a virtue ethics theory grounded in a specific notion of care. While there has been a recent revival of interest in virtue ethics theory, the theory has its roots in Aristotle's work as well in the medieval writings of Thomas Aquinas. Aquinas worked out many of Aristotle's ideas in much more detail. However, while Aquinas offers a very rich and compelling ethical theory, it is problematic because it is very tightly wrapped in his theology. A key component in Aquinas's theory is charity. Charity is one of …

Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar

USF Tampa Graduate Theses and Dissertations

In an effort to determine the optimal temperature for rearing Centropomus undecimalis larvae during the yolk resorption period, larval development was measured under four different temperature regimes (23, 25, 28 and 31 °C). The eggs were incubated at 28 °C until hatching, which occurred at about 17 hours post-fertilization. After hatching, temperatures were adjusted to the respective treatment levels. Measurements were collected from 25 individual larvae across rearing temperatures at the following pre-determined time intervals: at hatching, 24 hours post hatch (hph), 48 hph, and 72 hph. Morphometric measurements were obtained from photomicrographs, including yolk sac length and height, oil …

Development Of An Elisa For Eastern Equine Encephalitis Virus That Can Differentiate Infected From Vaccinated Horses, Andrea Bingham

USF Tampa Graduate Theses and Dissertations

Eastern Equine Encephalitis virus (EEEV) causes a fatal mosquito-borne virus that is vaccine preventable for horses. The conventional serological tests measure antibodies to the structural proteins of EEEV which are also found in the vaccine. This makes it difficult to differentiate infected and vaccinated animals (DIVA). Detection of antibodies to non-structural proteins (NSPs) is a theoretical strategy that would allow you to survey natural infections among vaccinated populations. This test would also allow for more accurate representations of the natural infection rate, vaccination rate, and help identify vaccine failures. The potential uses of the NSPs of Eastern Equine Encephalitis virus …

Assessment Of A Countywide Stormwater Pond Improvement Project: Impacts Of The Hillsborough County Adopt-A-Pond Program, Anthony Thomas Betts

USF Tampa Graduate Theses and Dissertations

Comparative research was conducted to assess the environmental impacts of the Adopt-a-Pond program, which operates throughout Hillsborough County, Florida. The Adopt-a-Pond program was established in 1992 and designed to address nonpoint pollution through outreach and stormwater pond enhancement. However, the program had never been thoroughly and scientifically evaluated. Therefore, assessments of water quality and vegetative characteristics were made at ninety Adopt-a-Pond participants and eleven control ponds to explore the potential impacts of the program on measurable environmental parameters. Statistical analysis of the results failed to demonstrate any statistically significant environmental improvements associated with the Adopt-a-Pond program, and measures of program …

_Alien_ Thoughts: Spectatorial Pleasure And Mind Reading In Ridley Scott's Horror Film, Cecilia Madeline Bolich

USF Tampa Graduate Theses and Dissertations

Pleasure experienced in an unpleasant film genre, like horror, has prompted numerous discussions in film studies. Noted scholars like Carol J. Clover and Noël Carroll have rationalized spectatorial enjoyment of a genre that capitalizes on human anxieties and complicates cultural categories. Clover admits that horror initially satisfies sadistic tendencies in young male viewers but then pushes them to cross gender lines and identify with the strong female heroine who defeats the film's threat. Carroll provides a basic explanation, citing spectators' cognitive curiosity as the source of pleasure. Both scholars are right to consider emotional, psychological, and cognitive experiences felt by …

Stable Isotope Studies Of Paleoenvironment And Paleoclimate From Afar, Ethiopia, Zelalem K. Bedaso

USF Tampa Graduate Theses and Dissertations

The sedimentary deposits of the Hadar Formation at Dikika and the Mount Galili Formation at Galili preserve a wealth of paleoenvironmental and paleoclimatic records spanning the last 5.29 Ma. Stable carbon and oxygen isotopic compositions of herbivore tooth enamel were analyzed for more than 600 specimens of 15 different taxa from 10 stratigraphic intervals. The application of carbon and oxygen isotopes here aims principally at reconstructing shifts in the relative abundance of C₄ grasses, and its implications for climate indicators including temperature, aridity, and seasonality. The full range of δ¹³C_enamel values throughout the Plio-Pleistocene signifies a …

The Portia Project: The Heiress Of Belmont On Stage And Screen, Ann Mccauley Basso

USF Tampa Graduate Theses and Dissertations

Until now, there has not been a performance history of The Merchant of Venice that focuses on Portia, the main character of the play. Although she has the most lines, the most stage time, and represents the nexus of the action, Portia has often been hidden in Shylock's shadow, and this dissertation seeks to bring her into the spotlight. The Portia Project is a contribution to literary and theatrical history; its primary goal is to provide a tool for scholars and teachers. Moreover, because of Merchant's notoriously problematic nature, the play invites different perspectives. By presenting the diverse ways that …

Automated Quantification Of Biological Microstructures Using Unbiased Stereology, Om Pavithra Bonam

USF Tampa Graduate Theses and Dissertations

Research in many fields of life and biomedical sciences depends on the microscopic image analysis of biological images. Quantitative analysis of these images is often time-consuming, tedious, and may be prone to subjective bias from the observer and inter /intra observer variations. Systems for automatic analysis developed in the past decade determine various parameters associated with biological tissue, such as the number of cells, object volume and length of fibers to avoid problems with manual collection of microscopic data. Specifically, automatic analysis of biological microstructures using unbiased stereology, a set of approaches designed to avoid all known sources of systematic …

Drug Courts Work, But How? Preliminary Development Of A Measure To Assess Drug Court Structure And Processes, Blake Barrett

USF Tampa Graduate Theses and Dissertations

The high prevalence of substance use disorders is well-documented among criminal offenders. Drug courts are specialty judicial programs designed to: 1) improve public safety outcomes; 2) reduce criminal recidivism and substance abuse among offenders with substance use disorders; and 3) better utilize scarce criminal justice and treatment resources. Drug courts operate through partnerships between the criminal justice, behavioral health and public health systems. Offenders participate in an intensive regimen of substance abuse treatment and case management while under close judicial supervision. Drug courts' effectiveness in reducing criminal recidivism and drug use has been documented through numerous primary studies as well …

Placing Reedy Creek Improvement District In Central Florida: A Case Study In Uneven Geographical Development, Kristine Bezdecny

USF Tampa Graduate Theses and Dissertations

This study is primarily about the theory of uneven geographical development. In an era when it is proclaimed that, through globalization, the world has become flat, the unevenness of economic and social development is often overlooked or suppressed. As the nexus between global and local processes, the urban space often becomes the site of conflict between those defining the hegemonic narrative of the space, from a global and flat perspective; and those experiencing heterogenous local narratives, whose uneven positions are reinforced by this hegemonic narrative.

This study explores the conditions of uneven geographical development in the urban space of central …
