USF Tampa Graduate Theses and Dissertations

Sweetwater Organic Community Farm is an organic farm and environmental education center located in Tampa, Florida. The farm employs the community supported agriculture (CSA) model, in which members pay a single fee before the growing season begins and receive a weekly or biweekly share of the ongoing harvest in return. Using multiple ethnographic methods, this research aimed to understand the daily operations at Sweetwater as well as the perceptions of staff and CSA members. Findings indicated that there were myriad perceived advantages of organic agriculture but also imposing challenges that needed to be overcome. Moreover, staff members acknowledged the challenges …

Masculinity, Sexuality, And Soccer: An Exploration Of Three Grassroots Sport-For-Social-Change Organizations In South Africa, Sarah Theresa Mcghee

USF Tampa Graduate Theses and Dissertations

Programs that utilize soccer as a tool for social change are steadily emerging throughout townships and rural areas in South Africa, the most economically disadvantaged areas of the country. In South Africa, grassroots sport-for-social-change organizations are compensating for failed government policies and programs that seek to help at-risk youth. As a result, program staff are often members of the community who are not versed in academic critiques of the use of sport in development initiatives. Additionally, much of the existing literature on sport-for-social-change champions the advancement of specific projects without asking critical research questions, which should include the appropriateness of …

Wrecking Recreation Center Relationships: How Policy Affects Urban Youth In Tampa, Florida, Brett A. Mervis

USF Tampa Graduate Theses and Dissertations

This dissertation explores the impact of housing and recreation policy on Tampa's urban youth. Deconcentration policy suggests that public housing youth have improved life chances when relocated to mixed-income neighborhoods. In 2007, Tampa's Central Park Village (CPV) public housing complex was demolished and all families were relocated to new neighborhoods. Similarly, neoliberal policy advocates for the government's reduced role in poverty-alleviating mechanisms to include housing the poor and the funding of afterschool programs. To offset a smaller city budget due to state property tax rollbacks in the mid-2000's, Tampa Parks and Recreation instituted increased afterschool and youth sports participation fees. …

A Longitudinal Examination Of High School Students' Group Membership In A Dual-Factor Model Of Mental Health: Stability Of Mental Health Status And Predictors Of Change, Melanie M. Mcmahan

USF Tampa Graduate Theses and Dissertations

A dual-factor model of mental health includes indicators of wellness (i.e., subjective well-being; SWB) and psychopathology (i.e., internalizing and externalizing behavior problems) in defining youth mental health. In this model, four categories of psychological functioning with distinct levels of SWB and psychopathology emerge, including two that are overlooked (i.e., Vulnerable and Symptomatic but Content) in traditional assessments that assume SWB and psychopathology are opposite ends of the same continuum. The present study investigated the 1-year stability of adolescent mental health as classified by a dual-factor model, and identified predictors of stability and change, in a sample of 425 high school …

Parental Leave: Policy And Practice, Amanda Parr

USF Tampa Graduate Theses and Dissertations

Parental leave is a broad term that encompasses maternity and/or paternity leave to care for an infant. Parental leave provides job protection for workers and may be paid or unpaid, with provisions varying throughout the world. Every industrialized nation offers some form of paid parental leave, with the exception of the United States, whose only federal policy regarding parental leave is the Family and Medical Leave Act (FMLA), a law that allows eligible workers to take up to twelve weeks of unpaid, job protected leave for the birth or adoption of a child.

This research project explored how parents understand …

Comparing Prompt Delay And Total Communication For Training Vocal Intraverbals In Children With Autism, Rosana Pesantez

USF Tampa Graduate Theses and Dissertations

Abstract

Verbal behavior encompasses a wide range of aspects in our everyday lives and in the activities of a society. Many verbal behavior interventions often include programs to teach answering questions, these responses are referred to as intraverbals. Previous research has demonstrated a higher rate of acquisition of verbal targets such as mands and tacts for children with a limited verbal repertoire when a presentation of both sign and vocal prompts occur simultaneously (Total Communication), in comparison to sign-alone or vocal-alone trainings. However, an important variable not often examined in the literature is the comparison of Total Communication (TC) and …

USF Tampa Graduate Theses and Dissertations

Abstract

This thesis investigates the use of socioscientific issues (SSI) in the high school science classroom as an introduction to argumentation and socioscientific reasoning, with the goal of improving students' scientific literacy (SL). Current research is reviewed that supports the likelihood of students developing a greater conceptual understanding of scientific theories as well as a deeper understanding of the nature of science (NOS), through participation in informal and formal forms of argumentation in the context of SSI. Significant gains in such understanding may improve a student's ability to recognize the rigor, legitimacy, and veracity of scientific claims and better discern …

Water's Dependence On Energy: Analysis Of Embodied Energy In Water And Wastewater Systems, Weiwei Mo

USF Tampa Graduate Theses and Dissertations

Water and wastewater treatment is a critical service provided for protecting human health and the environment. Over the past decade, increasing attention has been placed on energy consumption in water and wastewater systems for the following reasons: (1) Water and energy are two interrelated resources. The nexus between water and energy can intensify the crises of fresh water and fossil fuel shortages; (2) The demand of water/wastewater treatment services is expected to continue to increase with increasing population, economic development and land use change in the foreseeable future; and (3) There is a great potential to mitigate energy use in …

Walking In The Land Of Cars: Automobile-Pedestrian Accidents In Hillsborough County, Florida, Marc Aaron Poling

USF Tampa Graduate Theses and Dissertations

Analyses of traffic accidents are often focused on the characteristics of the accident event and hence do not take into account the broader neighborhood contexts in which accidents are located. This thesis seeks to extend empirical analyses of accidents by understanding the link between accidents and their surroundings. The case study for this thesis is Hillsborough County, Florida, within which the city of Tampa is located. The Tampa Bay region ranks very high in terms of accident rates within U.S. metropolitan areas and is also characterized by transport policies which favor private automobiles over mass transit options, making it an …

Responses To Chemical Exposure By Foraminifera: Distinguishing Dormancy From Mortality, Benjamin James Ross

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout in 2010 released an estimated 4.9 million barrels of crude oil into the Gulf of Mexico in the 83 days between the initial explosion and the capping of the well. Response included extensive use of Corexit© oil dispersant. Although South Florida was spared exposure by currents, this event highlights the need for effective bioassay organisms for coral reefs. Amphistegina spp. are benthic foraminifers that host diatom symbionts in a relationship similar to that of coral and their zooxanthellae. Amphistegina spp. occur abundantly in reef communities nearly worldwide, are easily collected and maintained in culture, and are …

Adolescents continue to be at increased risk for contracting sexually transmitted infections (STI's). This research study describes the perception of barriers that providers in the Tampa Bay area encounter when implementing primary STI prevention programs for adolescents within the community context. This study used semi structured interviews to explore perceived barriers for implementing primary such programs for adolescents in the Tampa Bay area programs. Participants reported faith based institutions/churches and schools as common sectors for presenting a variety of barriers for implementing their program. Perceptions of barriers were described as, the need to tailor program messages and presentations based on …

Tracing Boundaries, Effacing Boundaries: Information Literacy As An Academic Discipline, Grace L. Veach

USF Tampa Graduate Theses and Dissertations

Both librarianship and composition have been shaken by recent developments in higher education. In libraries ebooks and online databases threaten the traditional "library as warehouse model," while in composition, studies like The Citation Project show that students are not learning how to incorporate sources into their own writing effectively. This dissertation examines the disciplinary origins and current status of information literacy and makes a case for increased collaboration between Writing Studies and librarians and the eventual emergence of information literacy as a discipline in its own right. Chapter One introduces the near-total failure of information literacy pedagogy and the lack …

Changes In Attitudes And Behaviors Toward Physical Activity, Nutrition, And Social Support For Middle School Students Using The Afit App As A Suppliment To Instruction In A Physical Education Class, Thomas Andrew Watterson

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Finding ways to improve nutritional and physical activity components with today's adolescents is a significant problem. The obesity epidemic is over 10 years old and little research has been done on successful interventions that motivate today's students using the latest technology. A total of 140 middle school students and four physical education teachers participated in a 4-week study using a newly created application (AFIT app) for supplemental teaching in and out of the classroom. Combining a theoretical framework of Self-Determination and motivating strategies implored in today's mobile technology, significance was found using the PACE (2001) instrument in fruits and …

Use And Development Of Computational Tools In Drug Discovery: From Small Molecules To Cyclic Peptides, Daniel Navarrete Santiago

USF Tampa Graduate Theses and Dissertations

The scope of this work focuses on computationally modeling compounds with protein structures. While the impetus of drug discovery is the innovation of new therapeutic molecules, it also involves distinguishing molecules that would not be an effective drug. This can be achieved by inventing new tools or by refining old tools. Virtual screening (VS, also called docking), the computational modeling of a molecule in a receptor structure, is a staple in predicting a molecule's affinity for an intended target. In our Virtual Target Screening system (also called inverse-docking), VS is used to find high-affinity targets, which can potentially explain absorption, …

Assessing The Reuse Potential Of Wastewater For Irrigation: The Removal Of Helminth Eggs From A Uasb Reactor And Stabilization Ponds In Bolivia, Matthew Eric Verbyla

USF Tampa Graduate Theses and Dissertations

Extreme hunger, malnutrition, and the lack of access to sanitation are among the most pressing development challenges, but the world is not on track to meet the targets that have been established by the Millennium Development Goals. The integration of wastewater treatment and food production systems allows for the recovery of resources from wastewater, and can provide an important solution to meet the sanitation needs of growing urban populations and provide periurban farmers with a consistent supply of water and nutrients. Stabilization ponds have been long considered to be an appropriate technology for wastewater reuse systems in developing countries, but …

A Longitudinal Investigation Of Stress, Complete Mental Health, And Social Support Among High School Students, Ashley Chappel

USF Tampa Graduate Theses and Dissertations

Examinations of stress in relation to adolescent mental health have not often utilized a comprehensive definition of psychological functioning. Recent literature has found support for the importance of examining optimal psychological functioning as the presence of high life satisfaction in addition to low psychopathology (Antamarian, Huebner, Hills, & Valois, 2011; Suldo & Shaffer, 2008). Most research on stress has focused on either major stressful events or chronic environmental stressors; further research is needed on the psychological model of stress, which conceptualizes stress as involving both environmental events and one's cognitive appraisals of the stressor. The current longitudinal study determined how …

"People Aren't Mind Readers": A Study Of Sexual Self-Concept, Partner Communication, And Sexual Satisfaction, Heather Blunt

USF Tampa Graduate Theses and Dissertations

Sexual health is an important component to overall well-being and quality of life. Yet so much of sexual health research is focused solely on the negative consequences of sexuality, such as unintended pregnancy and transmission of sexually transmitted infections. Recently, the need for a positive, health promotion focused framework for research and understanding sexual health has received attention, including from the World Health Organization and the Centers for Disease Control and Prevention. This transition of public health research and practice from a disease-based framework to a positive, health promotion framework necessitates exploring what factors are associated with positive sexuality and …

Results indicated that socioscientific issues assist students in developing their critical thinking skills while also providing students …

Federal Neighborhood Stabilization Policy Deployment In Select Florida Jurisdictions, Kevin Carl Mccarthy

USF Tampa Graduate Theses and Dissertations

In 2008 the Federal government enacted a Neighborhood Stabilization Program (NSP) to address the neighborhood effects of the late-2000s foreclosure crisis. Congress subsequently funded a second and third NSP. This research employs mixed methods to examine the effectiveness of the first round of the NSP in three Florida jurisdictions. The results are analyzed within the larger context of substantive housing theory and federal housing policy. The success of the program is evaluated using a mixed-scanning procedural planning theoretical framework.

Ontogeny And Littoral Structure Of Lakes Created On Phosphate Mined Lands Of Central Florida, Chrysoula Mitraki

USF Tampa Graduate Theses and Dissertations

Created lakes are an end product of phosphate mining in Florida. Beginning in 1975, Florida reclamation rules set criteria for phosphate created lakes aiming to approximate the structure of natural lakes, and emphasizing extensive littoral zones with both emergent and submersed vegetation.

Lake development relative to lake age and design were examined for 22 phosphate lakes representing a 40-year age trajectory, utilizing water quality and benthic invertebrate communities from littoral and deep-water locations (Chapter 1). The relative importance of morphometry and lake age in the development of littoral plant communities was examined using multiple vegetation surveys throughout the year, in …

Engineering Of A Knowledge Management System For Relational Medical Diagnosis, Maria Carolina Herrera-Hernandez

USF Tampa Graduate Theses and Dissertations

The increasingly high costs of health care in the U.S. have led the general public to search for different medical approaches. Since the 1990's, the use of Complementary and Alternative Medicine (CAM) has radically increased in the U.S. due to its approach to treat physical, mental, and emotional causes of illness. In 2009, the National Health Statistics reported the impact of CAM in the U.S. health care economy, with population expenditures of $14.8 billion out-of-pocket on natural Medicine and $12.4 billion out-of-pocket on visits to CAM providers as a complement to Western Medicine care.

CAM interconnects human functions to reach …

A Novel Device And Nanoparticle-Based Approach For Improving Diagnosis And Treatment Of Pelvic Inflammatory Disease, Natasha Faith Cover

USF Tampa Graduate Theses and Dissertations

Pelvic Inflammatory Disease (PID) is one of the most common causes of morbidity in women. PID is a polymicrobial infection of the female reproductive tract, and is associated with pelvic pain, abnormal uterine bleeding, and tubal damage that can lead to ectopic pregnancies and infertility. It is curable but the effects of PID can be permanent if not properly diagnosed and treated. PID presents as a spectrum of disease and is often missed at early stages; even acute PID can be difficult to diagnose, as there is no single conclusive diagnostic test. Currently, PID is identified and treated syndromically because …

The Interrelationships Among Family Stress, Parenting Behavior, And Behavior Problems: An Investigation Of Internationally Adopted Chinese Girls, Cheryl Gelley

USF Tampa Graduate Theses and Dissertations

Although there have been many studies investigating international adoptees' outcomes in relation to their pre-adoption experiences, there is a paucity of research investigating the influence of post-adoption experiences. Guided by the proximity of the family to the child in Bronfenbrenner's (1979) ecological systems theory of human development, this study addressed a gap in the literature by investigating the interrelationships among family-related variables (e.g., stress in family environment, parenting behavior) and 648 internationally adopted Chinese girls' behavior problems. Moderate, positive relationships were found between family stress and both internalizing (r = .43, p < .001) and externalizing (r = .59, p < .001) behavior problems. Modest, inverse relationships were found between authoritative parenting and both internalizing (r = -.08, p < .01) and externalizing (r = -.15, p < .001) behavior problems. Additionally, modest to moderate, positive relationships were found between authoritarian and permissive parenting and internalizing (r = .18, p < .001; r = .19, p < .001, respectively) and externalizing (r = .39, p < .001; r = .34, p < .001, respectively) behavior problems. Finally, authoritarian and permissive parenting behaviors were partial mediators between family stress and both internalizing (R² = .08, p < .001; R² = .08, p …

Multisensory Integration In Shark Feeding Behavior, Jayne M. Gardiner

USF Tampa Graduate Theses and Dissertations

Multimodal sensory input directs simple and complex behaviors in animals. Most research to date has been limited to studies of individual senses rather than multiple senses working together, leading to important advances in our comprehension of the sensory systems in isolation, but not their complementary and alternative roles in difficult behavioral tasks, such as feeding. In the marine environment, a prey item might emit an odor, create a hydrodynamic disturbance, such as from gill movements or swimming, be visible to the predator, produce a sound, and/or produce a weak electrical field. Therefore, the goal of this study was to investigate …

The Relationships Between Individual Characteristics, Work Factors, And Emotional Labor Strategies In The Prediction Of Burnout Among Mental Health Service Providers, Jessica Belle Handelsman

USF Tampa Graduate Theses and Dissertations

Relatively few empirical studies in the professional burnout literature have examined mental health providers (MHPs). Research on other professional groups has demonstrated that certain emotion regulation strategies, known as emotional labor (i.e., deep acting and surface acting), are common responses to perceived display rules (i.e., professional guidelines for emotional expression), and are differentially associated with burnout. The present study aimed to fill a gap in the literature by evaluating the empirical links between work stressors (i.e., role conflict, role ambiguity, and lack of autonomy), personality (i.e., extraversion), emotional labor (i.e., surface acting and deep acting), and burnout in a sample …

A Reflexive Approach To Capability Valuation And Determination In Sustainable Human Development: The 2010 Hillsborough County Transit Referendum, Eric James Fiske

USF Tampa Graduate Theses and Dissertations

Sustainable Human Development (SHD), rooted in Amartya Sen’s development theory on the capability approach, envisions achieving sustainable human capabilities at the local and global levels. One major area of contention within this field of research concerns determination and valuation of capabilities. How a community decides which capabilities should be developed is as important as the development itself. Some capability scholars argue that a small group of experts or “philosophers” should make this determination, while others argue that a deliberative democratic process needs to be followed. I seek to reconcile these two positions by introducing a third way of determining and …

Store-Operated Calcium Channels In The Function Of Intracardiac Neurons, Timetria Bonds

USF Tampa Graduate Theses and Dissertations

Proper autonomic regulation of mammalian cardiac function is dependent upon very complex and precise communication among the intracardiac ganglia and individual neurons within the ganglia. An array of neuromodulators is found within the ganglia that direct neuronal activity by modulating the movement of calcium. The current study determines that opioidergic agonists, which have been found to contribute to severe cardiac disease states and intracellular calcium mobilization, are also responsible for changes in the function of the intracardiac neuron via their effects on store-operated calcium channels (SOCs).

Previous studies suggest that phosphorylation plays a role in SOC regulation. Using Fura-2 calcium …

The Invasive Cactus Moth, Cactoblastis Cactorum: Host Plant Testing, Species Interactions, And Effects On Local Opuntia Populations, Heather Jezorek

USF Tampa Graduate Theses and Dissertations

The invasive cactus moth, Cactoblastis cactorum, poses a threat to opunitoid cacti species of North America. The following work contains four separate studies investigating C. cactorum host plant preference and performance, predation and parastitism of C. cactorum, effects of C. cactorum on local Opuntia populations, and associational effects of host and non-host plants on C. cactorum and native Opuntia-feeding herbivores. We found that, among southwestern and Mexican opuntioid taxa, moths preferred O. engelmannii var. linguiformis and var. engelmannii for oviposition, while Consolea rubescens and O. streptacantha were superior larval hosts. Oviposition was best predicted by number of cladodes and degree …
