Education In The Settler Colony: Displacement, Inequality, And Disappearance Via Charter Schools, David R. Fisher

USF Tampa Graduate Theses and Dissertations

The encroachment of market-based practices on public education has resulted in the creation of vouchers, charter schools, virtual schools, home schools, and other forms of educational choice. While there has always been choice in education in the United States for the wealthy and White, the current conception of school choice, in theory, allows equal access to education for all. Undergirding the neoliberal practice of school choice is a connection to a troubling past of capitalist oppression and settler colonialism. Like settler colonialism, the practice of school choice has resulted in the displacement of educators, families, and students, inequality between different …

Past Climate And Sea-Level Reconstruction Using Cave Deposits From Mallorca, Spain, Oana-Alexandra Dumitru

USF Tampa Graduate Theses and Dissertations

The potential impacts of the increasing temperature on the water resources, as well as the hazards associated with the sea-level rise in the low-elevation coastal zones of the Mediterranean Sea, makes this region vulnerable to current climate change due to global warming. Hence, accurate projections of the future hydroclimate scenarios in this area are crucial. Long-term information on climate and sea-level variability cannot be obtained by direct observations or using short instrumental records. However, various geological archives may provide valuable data that can be then used to assess the models used for future predictions.

This thesis presents results on past …

Book-Sharing As A Context For Fathers And Mothers To Enhance Language Development Of Their Preschool Children, Yagmur Seven

USF Tampa Graduate Theses and Dissertations

Poor reading levels is a pervasive problem in the US. For example, two of every three eigth grade students in the US are estimated to demonstrate insufficient reading comprehension skills. Early use of decontextualized language, in which the language expressed is removed from the here and now, serves as a precursor of academic language proficiency. Starting as early as the third year of life, decontextualized language is less likely to be practiced in lower socio-economic status (SES) households. Although storybooks offer a rich context for practicing the language with young children, reading storybooks alone is not adequate to promote conversational …

Development Of Α-Aa Peptides As Peptidomimetics For Antimicrobial Therapeutics And The Discovery Of Nanostructures, Sylvia E. Singh

USF Tampa Graduate Theses and Dissertations

For decades it has been convention to use antibiotics for the treatment of bacterial infections. Due to the overuse and misuse of these drugs, bacteria are becoming resistant to these treatments. This phenomenon has led to the search for alternative antibiotics, and in the study of Host Defense Peptides (HDPs). HDPs are the body’s innate immune response to infection. They are known to modulate immune system response and kills bacterial using various methods causing them to be less susceptible to bacterial resistance. The method by which we can mimic these biological peptides is called peptidomimetics. Various research shows the use …

Life After Graduation: Current Seniors' Perceptions Of Alumni Engagement And Their Expectations Of The Institution Once They Graduate, Jessica Burns Fugate

USF Tampa Graduate Theses and Dissertations

Alumni participation in the life of an institution is more important now than ever before as state and federal funding continue to shrink and alumni are called on for financial support and to serve as resources for current students. Institutional leaders are hard-pressed to bring in external revenue to bridge the gap as budgets shrink to successfully balance operational costs (Barr & McClellan, 2011), which is done mostly through fundraising efforts targeted toward parents of students, alumni and often current students before they graduate to establish a culture of philanthropy. This need for external revenue increases the necessity for engaged …

Health-Promoting Behaviors And Subjective Well-Being Among High School Students, Nicholas David W. Smith

USF Tampa Graduate Theses and Dissertations

In positive psychology, a greater emphasis is placed on the presence of indicators of both physical and mental health. This study examined the relationship between 12 health-promoting behaviors and subjective well-being (SWB; e.g., happiness) in a sample of 450 high school aged youth from five high schools in two states. Participants reported on their dietary habits, physical activity, abstinence from tobacco products, abstinence from alcohol, and sleep hygiene (i.e., 8 unique components) as well as a multidimensional assessment of SWB (i.e., life satisfaction, positive affect, and negative affect). It was hypothesized that increased engagement in each of the health-promoting behaviors …

Highway Lane Management Policy For Existing And Connected Autonomous Vehicles, Md Mokaddesul Hoque

USF Tampa Graduate Theses and Dissertations

Trucks carry major bulk of freight in the U.S. and are likely to continue doing so in the near future for various reasons. They have tremendous impact on highway pavement design and on the costs of pavement construction, maintenance, and rehabilitation. Current policy of truck lane restriction ensures that they mostly use the outside lane(s) on multilane highways. This practice has considerable impact on the cost of pavement construction and rehabilitation. Right now, all the highway lanes are designed and constructed according to the truck load on the outside lane even though the inside lanes receive significantly smaller quantity of …

A Comparison Of Different Modeling Techniques To Establish Token Reinforcers In Classroom Settings, Spencer B. Gauert

USF Tampa Graduate Theses and Dissertations

Prior research has supported the use of reinforcer-based methods in school settings. Video based modeling methods for establishing conditioned reinforcers without the need for explicit pairing with primary reinforcers can help to extend the use of these resources into new contexts. The use of video based conditioning has potential applications in school settings to increase academic skills without the use of more costly-to-implement reinforcer systems. However, conditioning of this kind might be restricted by the need to individually condition stimuli with different participants. The current study evaluated effects of video based conditioning on relative rate of sight word reading across …

Reducing Underrepresentation: Promising Practices In Florida, Catherine A. Mullins

USF Tampa Graduate Theses and Dissertations

In this study, I examined representation rates of gifted students from diverse backgrounds in Florida county school districts. Florida state legislation governing gifted student education allows for alternative identification methods to be used for students from underrepresented groups if plans for such identification are approved by the Florida Department of Education; however, this option, informally referred to as “Plan B” after subsection B of the legislation governing gifted services, is not a requirement that districts must follow. Consequently, there are large differences in the ways districts identify underrepresented students for gifted services. State legislation identifies underrepresented populations as students with …

Investigating Among-Individual Growth Heterogeneity In Longleaf Pine: Advancing Dendrochronological Approaches, Jamie E. Munn

USF Tampa Graduate Theses and Dissertations

Within a population, individuals frequently differ in the rate at which they grow, and this rate can be impacted by both genetic differences and abiotic factors. Often, dendrochronology is used to elucidate growth trends based on climate or other factors. This dissertation explores new statistical approaches to dendrochronological research.

First, I created a chronology for a population of longleaf pine (Pinus palustris P. Mill.) individuals in a southwest Florida sandhill community. I then used generalized linear mixed models to investigate the effects of fire frequency, year, tree age and size, and elevation on variation in radial growth heterogeneity. I then …

The Chemical Ecology And Drug Discovery Potential Of The Antarctic Red Alga Plocamium Cartilagineum And The Antarctic Sponge Dendrilla Membranosa, Andrew Jason Shilling

USF Tampa Graduate Theses and Dissertations

Chemical ecology is the study of chemical interactions between organisms and their environment mediated by small molecules involved in nonessential physiological functions, known as secondary metabolites. These compounds can be crucial to survival of the organism, and have also provided the field of medicine with some of history’s most influential drugs, referred to in that context as natural products. Antarctica is a dynamic and understudied environment, which affords the opportunity to examine the chemical ecology of unique organisms while simultaneously evaluating their novel chemistry for potential therapeutic properties as natural products.

Plocamium cartilagineum is a red macroalgal species found in …

“We Can Learn Some Things From Them, But They Can Learn Some Things From Us Too”: Intergenerational Perceptions Of Shared Infant Feeding Information, Alexis L. Woods Barr

USF Tampa Graduate Theses and Dissertations

Breastfeeding is associated with unparalleled benefits for infants, mothers, families and society. In light of the breastfeeding disparities and health disparities experienced by the African American community, their women and children stand to gain the most from breastfeeding practices compared to other first-food feeding methods. Moreover, African American mothers are constantly exposed to messages, images, and stereotypes about motherhood (from multiple channels of communication) which influences their infant feeding practices. Many of these exposures send mixed messages and tend to be cultural contradictions of Black motherhood. What complicates this issue is the shortage of research that investigates the intergenerational infant …

“Man Plans But Ultimately, God Decides”: A Phenomenological Investigation Of The Contextual Family Planning Beliefs Of Recently Resettled Congolese Refugee Women In West Central Florida., Linda Bomboka Wilson

USF Tampa Graduate Theses and Dissertations

Existent demographic changes in the United States are largely a result of the current international refugee crisis. Within the past three years, there has been an influx of refugees who were affected by the wars in the Democratic Republic of Congo (DRC). Congolese refugees were the highest number of all refugee groups to arrive in the United States in Fiscal Years 2016-2018, yet little is known about their lived experiences, particularly as they apply to reproductive health and family planning in general. Congolese refugee women who resettle in the United States are unique because many lived in refugee camps for …

Millimeter-Wavelength Characterization Of The Co Emission Of Comets 174p/Echeclus, 29p/Schwassmann-Wachmann, And C/2016 R2 (Panstarrs), Kacper Wierzchos

USF Tampa Graduate Theses and Dissertations

Comets are fascinating minor solar system bodies. They contain some of the most pristine and unprocessed material found in the solar system. As a comet approaches the Sun it displays the characteristic cometary coma and tail. This is due to the release of volatile species through a variety of processes. In the present work I studied the carbon monoxide emission of three very unique comets; 174P/Echeclus, 29P/Schwassmann-Wachmann and C/2016 R2 (PanSTARRS) with different radio telescopes at millimeter wavelengths. After molecular hydrogen, carbon monoxide is the second most abundant molecule in the universe, and is also the most volatile of the …

(Re)Making Worlds Together: Rooster Teeth, Community, And Sites Of Engagement, Andrea M. M. Fortin

USF Tampa Graduate Theses and Dissertations

My research examines the communicative practices by which fans of the entertainment brand Rooster Teeth (RT)—with millions of members around the world engaged with one another through in-person meetups, as well as a variety of digital spaces — constitute community. I study these moments in communication in terms of sites of engagement, or real-time windows where actions occur through the intersection of people, mediational means, and social practices. My research is important for a contemporary understanding of communities, as well as being critical in considering how our online and offline practices are inextricably tied in ways we have only begun …

Taking An “Ecological Turn” In The Evaluation Of Rhetorical Interventions, Peter Cannon

USF Tampa Graduate Theses and Dissertations

This dissertation seeks to develop a new method for the evaluation and assessment of therapeutic libraries in a health ecology. To do so, I employ a modified version of Lloyd Bitzer’s rhetorical situation as a methodological tool for the investigation of health ecologies by applying an ecological analysis to an alcohol and other drug (AOD) treatment center in Tampa, Florida. By modifying Bitzer’s rhetorical situation schema and expanding the concept of health ecologies, I develop several innovations useful for tracing the impact of actants and rhetorical events specific to health and medicine. A major focus of this dissertation is a …

Perceptions Of The Effectiveness Of Food Policy Coalitions In Strengthening Community Food Security In The United States., Joseph G. England Iii

USF Tampa Graduate Theses and Dissertations

Food insecurity is experienced most acutely and addressed most innovatively at the community level to which the concept of community food security (CFS) finds purchase (Hamm and Bellows, 2003). In recognition of the many varying dynamics embedded in the CFS concept, Food Policy Coalitions have become an organizational model adapted by communities across the United States. While FPCs have grown in number considerably over the last decade, there remains a considerable lack of empirical research documenting evaluation and engagement methods, as well as strategies used to address community food security. This research, framed by the Community Coalition Action Theory, draws …

Building A Collaborative Culture In A Middle School: A Case Study, Andrew Olson

USF Tampa Graduate Theses and Dissertations

There is extensive research indicating the importance of teachers working together in teams and in conjunction with school leadership to improve teaching practice and, ultimately, outcomes for students. However, there is little evidence that collaboration is valued in the American school system. Tension pervades in a system that often prescribes a top-down approach to teacher evaluation, fails to provide sufficient time for teachers to collaborate, and unfairly scapegoats teachers for many challenges both within society and the education system itself. It is not surprising that teachers are leaving the profession at an alarming rate.

Combine these contextual factors with the …

An Assessment Of The Role Of Florida Pharmacists In The Administration Of Inactivated Influenza Vaccine To Pregnant Women, Oluyemisi O. Falope

USF Tampa Graduate Theses and Dissertations

The influenza vaccine is a safe and effective vaccine in preventing influenza infection in the general population. The Centers for Disease Control (CDC) recommend that pregnant women receive influenza inactivated vaccine (IIV) due to the high morbidity and mortality associated with influenza infection in pregnant women. Despite the recommendation, the U.S. national influenza vaccine uptake rates among pregnant women continue to remain low. Studies have shown barriers to influenza vaccine uptake in pregnant women to include issues with access, unavailability of vaccine, and lack of time during prenatal visits. These barriers can be overcome using pharmacists because, among healthcare providers, …
