Data indicated that implementation of the group contingency preferred by the teachers in conjunction with data-based decision making resulted in decreases in disruptive behavior and increases in academic engagement and academic performance across classrooms. In addition, improvement in …

Tough Guy, Sensitive Vas: Analyzing Masculinity, Male Contraceptives & The Sexual Division Of Labor, Kaeleen Kosmo

USF Tampa Graduate Theses and Dissertations

A Marxist feminist standpoint positions patriarchy and capitalism as mutually beneficial, thus interestingly situating the new market of male contraceptives (MCs). This project takes an in-depth look at the opinions of 15 young men regarding the use of MCs by examining how Western, heterosexual masculinity informs their attitudes and discusses how a new economic market of MCs may affect current social ideologies about of the sexual division of labor. Because notions of masculinity are essential in perpetuating such ideologies, understanding masculinity as it relates to a new market for MCs is imperative. During a series of focus groups men described …

An Examination Of Perspectives On Community Poverty: A Case Study Of A Junior Civic Association, Monica Heimos Heimos

USF Tampa Graduate Theses and Dissertations

Nonprofit organizations have become a necessary staple in the lives of people and communities experiencing poverty. Many of these organizations provide services that they think their communities need. The solutions and services these organizations provide are incumbent on what the organizations think causes poverty. Although the motivations behind these organizations have good intentions, their approach to poverty could further jeopardize people and communities by not providing proper or necessary services that have the ability to help people get out of poverty. To explore how organizational values and perspectives on poverty are operationalized, I examined one nonprofit grassroots organization in Tampa …

Does Physical Fitness Predict The Reading Achievement Of Fifth-Grade Students? The Interaction With Gender, Courtney Lynn

USF Tampa Graduate Theses and Dissertations

States across the nation are facing pressure to meet standards for high stakes testing which is resulting in a decrease in the amount of time allotted to physical education (Ennis, 2006). Although the U.S. Department of Health and Human Services (2008) recommends children engage in 60 minutes or more of physical activity a day, on average, children only receive 30 minutes per day of aerobic exercise (Epstein et al., 2001). Despite this decrease in physical activity, research has shown that physical activity is associated with academic achievement (Ardoy et al., 2013). In addition, physical activity is positively related to physical …

To Utopianize The Mundane: Sound And Image In Country Musicals, Siyuan Ma

USF Tampa Graduate Theses and Dissertations

Many consider music, songs, and dance performance as utopian signifiers for cinema, but few has entered the utopian discourse of country musicals, a small genre of cinema usually known as country music films. By closely scrutinizing Pure Country (1992), this thesis aims to reveal how country music—as music numbers and as background cues— integrate and connect the fragmented on-screen world for the country musicals so as to offer audiences a fullness of utopian experience, and how this utopian effect are culturally significant for American audiences due to country music’s unique mechanism of constructing utopia and nostalgia in its past-orientations, sentimentalities, …

Water Metering In Rural, Piped, Community-Managed Water Systems In The Developing World, Simona Platukyte

USF Tampa Graduate Theses and Dissertations

In the early 1990s, the United Nations (UN) recognized water as a finite resource to the entire ecosystem with an economic value that should be developed and managed based on the participatory approach using the Integrated Water Resource Management (IWRM) strategy. Many studies on water management practices have thus emerged in the developing world. Of particular interest to this work is the management of water through metering, price-setting, and rule enforcement in the rural setting in piped, community-owned water systems. There is very little published information regarding metering, enforcement experiments, and experiences in these systems. This is because metering and …

USF Tampa Graduate Theses and Dissertations

A third of youth in the United States are currently classified as overweight, which is impacted by the low rates of youth that meet daily physical activity recommendations. Engaging in physical activity contributes to healthy body weight and physical fitness, both of which have positive health consequences. Participating in physical activity not only aids in positive health outcomes, but research indicates that it also has a positive relationship with and effect on youths’ cognitive, academic, and behavioral outcomes. The majority of researchers conducting meta-analyses examining the effect of physical activity on youths’ cognitive, academic, and behavioral outcomes have excluded single-case …

"But Our Hands Are Tied": Assessing School Gardening Efforts At Title I Elementary Schools In Pinellas County, Florida, Alexandra Grace Lancey

USF Tampa Graduate Theses and Dissertations

This research was designed to understand current school gardening efforts in Pinellas County, Florida. School gardens have become an important aspect of experiential learning and nutrition education in schools throughout the United States. Many not-for-profit organizations have attempted to increase the prevalence and efficacy of school garden programs as a means of providing educational opportunities and working to curb diet-related health issues in children. Most of these organizations are seen as apolitical in nature, because they access mainly private sector funding sources and volunteer support. This provides flexibility for these social projects, but also takes pressure off of the state …

Developing Little England: Public Health, Popular Protest, And Colonial Policy In Barbados, 1918-1940, Brittany J. Merritt

USF Tampa Graduate Theses and Dissertations

This dissertation analyzes struggles over the development of Barbadian health and sanitation during the period between the world wars. In doing so, it examines how the British Empire tried to use development policies to maintain its power overseas during the interwar years. During this period, British policymakers sought to improve health and sanitation to pacify restive Barbadian laborers influenced by transnational pan-African and socialist ideas following the First World War. However, white Barbadian elites, influenced by ideas of eugenics and population control, opposed metropolitan efforts to develop health and sanitation in the colony. Rather than repairing the colonial relationship, British …

Modified Yttrium Hydroxide/Mc Nylon Nanocomposites And Scaling Effects In Multilayer Polyethylene Films, Jia Chen

USF Tampa Graduate Theses and Dissertations

In this thesis, monomer casting (MC) nylon was synthesized. MC nylon could replace nonferrous metals in certain applications, including gears, wheels, and other moving parts. However, compared with metals, MC nylon products have poor strength and stiffness, and crack easily, especially at low temperatures. In addition, the dimensional stability of MC nylon is poor, especially in the large casting nylon products, causing significant internal stresses due to shrinkage. Thus, MC nylon cracks easily when cast and molded. The yttrium hydroxide particles were modified by stearic acid and dispersed in the caprolactam. The polymerization time was short due to fast anionic …

Regulatory Effect Of Elastin Based Biomaterial On Cellular Behavior And Its Application On Wound Repair And Regeneration, Yuan Yuan

USF Tampa Graduate Theses and Dissertations

Elastin-like peptides (ELPs) are stimulus-responsive protein-based polymers which are attractive material for biomedical research due to their biocompatibility and unique properties. The physical properties of ELPs are dependent on the chain length and the chosen amino acid at the guest residue position. This imparts unlimited flexibility in designing ELP based biomaterials with the desired physical properties.

We have shown that in addition to their physical properties, ELPs have biological activities that are conducive to tissue regeneration. Specifically, we found that ELPs induce fibroblast proliferation via cell surface heparan sulfate proteoglycans (HSPG). Furthermore, our data suggests that ELP based materials with …

In Search Of Solidarity: Identification Participation In Virtual Fan Communities, Jaime Shamado Robb

USF Tampa Graduate Theses and Dissertations

This study questions the way sports fans create (a sense of) community through online conversations. Here, ‘community’ and ‘internet’ are seen as invitational terms that suggest an authentic social interaction. By examining the language used by fans to sustain a sense of solidarity in the virtual realm, this study questions the ways in which rhetoric frames the situation. Participation in the virtual space relies on practices of identification derived from physical engagements. By using a rhetorical approach, this study illuminates the way individual participants operationalize a rhetoric in virtual conversations that spiritualize the fan’s experience at the base of a …

The Path To Violent Behavior: The Harmful Aftermath Of Childhood Trauma, Nicholas Michael Perez

USF Tampa Graduate Theses and Dissertations

Adverse childhood experiences can lead to a number of harmful outcomes throughout an individual’s life, ranging from medical problems to criminal behavior. These traumatic experiences, comprised of different forms of maltreatment and dysfunctional household environments, can affect the development of a child in a variety of different ways. The multitude of developmental changes can produce compounding harmful effects on the child’s life and lead to acutely maladaptive outcomes. Under the perspective of developmental psychopathology, the ever-changing biological, psychological, and social dynamics of children who experience trauma can contribute to deficiencies in all aspects of their subsequent development. Each of these …

Incongruous Conceptions: Owen Jones’S Plans, Elevations, Sections And Details Of The Alhambra And British Views Of Spain, Andrea Marie Johnson

USF Tampa Graduate Theses and Dissertations

This thesis analyzes Plans, Elevations, Sections, and Details of the Alhambra (1836-1842) by British Architect Owen Jones in relation to British conceptions of Spain in the nineteenth century. Although modern scholars often view Jones’s work as an accurate visual account of the Alhambra, I argue that his work is not only interested in accuracy, but it is also a re-presentation of the fourteen-century monument based on Jones’s ideologies and creative faculties. Instead of viewing the Alhambra through a culturally sensitive, historical lens, Jones treated it as an Imaginary Geography, as Edward Said called it, through which he could promote his …

The Effects Of Processing Instruction On Chinese Learners' Acquisition Of Spanish Copulae, Wesley Curtis

USF Tampa Graduate Theses and Dissertations

Processing instruction (PI) is a language teaching technique based upon the model of input processing developed by VanPatten (1993, 1996, 2002, 2004). The present study investigated the effects of PI as well as two other experimental conditions (traditional instruction and control) on the acquisition of the Spanish copulae ser and estar by 66 Chinese university students enrolled in a blended (partially presential and partially online) fourth-semester language course. The PI treatment condition included non-paradigmatic grammar explanations, processing strategies designed to help learners avoid commiting errors they may be predisposed to make, and structured input activities which eliminate redundant features of …

Label Noise Cleaning Using Support Vector Machines, Rajmadhan Ekambaram

USF Tampa Graduate Theses and Dissertations

Mislabeled examples affect the performance of supervised learning algorithms. Two novel approaches to this problem are presented in this Thesis. Both methods build on the hypothesis that the large margin and the soft margin principles of support vector machines provide the characteristics to select mislabeled examples. Extensive experimental results on several datasets support this hypothesis. The support vectors of the one-class and two-class SVM classifiers captures around 85% and 99% of the randomly generated label noise examples (10% of the training data) on two character recognition datasets. The numbers of examples that need to be reviewed can be reduced by …

Relationship Between First-Generation College Students' Expectations For Experiences With Faculty Members And Students' Success After The First Year, Christina D. Nelson

USF Tampa Graduate Theses and Dissertations

As the landscape of higher education changes to allow increased access for first-generation college students (FGS), emerging research should take into account the unique nature of this at-risk population of students (Aspelmeier, Love, McGill, Elliott, & Pierce, 2012). These students tend to be less prepared for the rigors of college coursework (Horn & Bobbitt, 2000; Strayhorn, 2006; Thayer, 2000) and may lack appropriate expectations (Pascarella, Pierson, Wolniak, & Terenzini, 2004). In particular, FGS may struggle with understanding the importance of creating and maintaining relationships with faculty (Cotten & Wilson, 2006; Davis, 2010).

In order to discover any correlation between expectations …

USF Tampa Graduate Theses and Dissertations

This study investigates children’s peer culture, social networks and the role that kids’ food plays in peer exchanges during middle childhood. During this stage children develop social competencies as they join peer groups with other children and become socialized into children’s peer culture. In order to immerse myself within children’s culture, I conducted ethnographic fieldwork at two afterschool programs providing care for elementary school children. I investigated friendships, social networks and exchanges among third through fifth grade children at the programs. The study included participant observation and participatory group interviews with a sample of the children at both sites. The …

Neurophysiological Activity Related To Speech Production: An Erp Investigation, Adithya Chandregowda

USF Tampa Graduate Theses and Dissertations

The event related potential (ERP) technique is enjoying widespread application in neurophysiological research due to its fine temporal resolution. Of relevance to this study are ERPs related to voluntary movements. The precision with which movement related processes could be recorded using the ERP technique was demonstrated by Gilden, Vaughan and Costa (1966) and Kutas and Donchin (1974, 1977, and 1980) who found that the readiness potential (RP) immediately preceding hand movement was larger over the hemisphere contralateral to the responding hand. Given that left hemisphere controls right hand movements and vice versa, their findings confirmed that the lateralized readiness potential …

Predictive Analytics Of Organizational Decisions And The Role Of Rationality, Arash Barfar

USF Tampa Graduate Theses and Dissertations

How can we predict key decisions made by organizations in the presence of big data and on-demand information? In this dissertation we exploit a large repository of B2B real-time transactional data with service quality indicators and present evidence that organizational decision analytics apply both rational and boundedly-rational (i.e. behavioral) economic models. The dissertation’s findings demonstrate that both utility and heuristic models, respectively, play significant roles in predicting organizational decisions on churn, a key decision in this context. In the presence of a large data set the assumed rationality of organizations appears to provide accurate predictions in uncontrolled experiences and selected …
