Perceived Discrimination And Cardiovascular Outcomes In Blacks: A Secondary Data Analysis Of The Heart Score Study, Marilyn Aluoch

USF Tampa Graduate Theses and Dissertations

Despite the consistent reduction in morbidity and mortality associated with cardiovascular disease (CVD) over the last four decades, CVD remains the leading cause of death globally. In the United States, Blacks are disproportionately affected by CVD compared to Whites. Blacks are also more likely to report incidence of perceived discrimination. Perceived discrimination has been linked to cardiovascular risk factors such as smoking, hypertension (HTN), hyperlipidemia, and obesity. However, the relationship between perceived discrimination and cardiovascular outcomes such as stroke, myocardial infarction, acute ischemic syndrome, coronary revascularization, and cardiac death remains unclear. The primary goal of this study was to examine …

The Progressive Transformation Of Medellín- Colombia: A Successful Case Of Women's Political Agency, María Auxiliadora González-Malabet

USF Tampa Graduate Theses and Dissertations

Medellín, Colombia, once one of the most corrupt and violent cities in the world, is now one of the most progressive and democratic cities in South America. This transformation was due to the mobilization of women’s movements and the influx of women in the city’s executive branch. Female political agency and new urban development programs reshaped democratic practices for the citizenry. This research examines the robust association between women’s organizations, women from Compromiso Ciudanano (CC), and a solid and active civil society. The theoretical framework covers democratization, good governance, and Latin American/Indigenous Feminism. The sources include interviews, polls, news articles, …

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 …

The Role Of Secreted Proteases In Regulating Disease Progression In Staphylococcus Aureus, Brittney D. Gimza

USF Tampa Graduate Theses and Dissertations

Staphylococcus aureus is a highly successful pathogen capable of producing a wealth of virulence factors in the human host. Of note, ten extracellular proteases are produced alongside these virulence factors and play a multifaceted role during infection. They not only cleave host proteins to promote bacterial invasion, immune evasion and survival, but also control disease progression by modulating the stability of self-derived pathogenic determinants. The importance of the secreted proteases modulating virulence factor stability is evidenced by our groups previous finding that a protease-null strain has a substantially increased infectious capacity in a murine model of sepsis; resulting from the …

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 …

Engineering Career Academies: A Comparison Of Middle School Student Academic Performance, Jakub D. Prokop

USF Tampa Graduate Theses and Dissertations

A quasi-experimental study tested an integrated curriculum design in two career academies with engineering themes at the middle school level. Teachers in the engineering career academies, using the National Standards of Practice, implemented cross curricular units to middle school student cohorts. Participant cohorts ranged in sample sizes (n = 79, 155, 237, and 232) during the four years of analysis. Constructivism was used as a framework for the study and supported by integrated curriculum units. This study examined middle school students’ performance in reading and mathematics on state assessments of students in the engineering career academies to students not enrolled …

Cactus-Based Mucilage As A Natural Dispersant For Crude Oil Spills, Fei Guo

USF Tampa Graduate Theses and Dissertations

Oil spills are a critical threat to the marine environment, and the spilled oil as a source of pollution can have long-term adverse effects on the marine ecosystem. Traditional mechanical clean-up operations have apparent advantages for dealing with small and medium-scale oil spills. For large-scale oil spills, dispersants are a practical and minimally influential approach to the environment. As the dispersant components are iteratively updated, dispersants become more efficient and safer. However, the toxicity of the dispersants remains a significant impediment to their application. An efficient and non-toxic dispersant is increasingly becoming a requirement.

The cactus mucilage extracts studied in …

The Adaptations Of The Sulfur-Oxidizing, Gammaproteobacterium "Candidatus Endoriftia Persephone", Endosymbiont Of The Giant Tubeworm Riftia Pachyptila, To Hydrothermal Vent Habitat Heterogeneity, Juliana M. Leonard

USF Tampa Graduate Theses and Dissertations

The siboglinid tubeworm Riftia pachyptila is a dominant member of the deep-sea megafauna where seawater and hydrothermal vent (HTV) effluent interface and mix. It is one of the fastest growing invertebrates on land or in the sea. It does not have a digestive tract (e.g. mouth, gut, or anus), and is completely dependent on its sulfur-oxidizing endosymbiont, the Gammaproteobacterium “Candidatus Endoriftia persephone” for its nutritional requirements. This association was the first and is the most well studied among chemolithoautotrophic symbioses. “Ca. E. persephone” is a chemolithoautotrophic bacterium that oxidizes sulfide as an electron donor for energy, reduces oxygen as a …

“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 …

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 …

Epidemiological Analysis Of Malaria Decrease In El Salvador From 1955 Until 2017, Tatiana I. Gardellini Guevara

USF Tampa Graduate Theses and Dissertations

The disease of malaria is complex, with clinical presentation that ranges from severe and complicated to mild and uncomplicated or even to asymptomatic malaria. A recent effort made by several world organizations has shown important advances in the effort to control and eradicate malaria. Following the general ordinance established by the trans-border organizations, each country has tried to define, according to their local geopolitical scenario, individual ¨road maps¨ to succeed in reducing the morbidity and mortality caused by malaria. Moreover, it is now accepted universally that these road maps need to be revised and appropriated in order to correct actions …

Chemolithotrophic Denitrification Of Nitrate Contaminated Groundwater Using Sulfur-Bearing Minerals, John Sutton

USF Tampa Graduate Theses and Dissertations

Nitrate contamination in groundwater resources poses a serious threat, not only to the health of those who would drink it, but also as a potential nutrient for eutrophication. Current methods of nitrate removal can efficiently remove nitrate below 10 mg/L as nitrogen, but may require resources unavailable to small community water systems (SCWS). Sulfur-oxidizing biological denitrification is a promising alternative that may be more suitable for SCWS. Sulfur-oxidizing denitrification has previously been shown to have a high nitrate removal efficiency; however, it produces water high in sulfate. Utilization of sulfide-bearing minerals, rather than elemental sulfur as an electron donor, may …

Pathways To Parenthood: Attitudes And Preferences Of Eight Self-Identified Queer Women Living In Tampa Bay, Fl, Emily Noelle Baker

USF Tampa Graduate Theses and Dissertations

This small-scale ethnographic study looks at the how queer women living in Florida imagine navigating family building decisions under the current climate of policies such as a lack of federal non-discrimination protections and the largely unregulated use of assisted reproductive technologies. Despite the federal legalization of same-sex marriage in the United States in 2015, state and county legislations continue to vary greatly on the extent of support they will provide for LGBTQ families. The goal of this research is to evaluate parenting desire, intentions, and preferences for queer women living in Tampa Bay since the passage of the Marriage Equality …

Investigating The Effects Of Motivational Interviewing Compared To Action Planning On Supporting The Emotional And Academic Success Of Ninth Grade Students In Advanced Placement Classes, Kai Zhuang Shum

USF Tampa Graduate Theses and Dissertations

High school students in accelerated curricula (i.e., Advanced Placement classes or pre-International Baccalaureate program) tend to report higher level of perceived stress compared to general education students due to additional academic demands that stemmed from accelerated courses (Suldo & Shaunessy-Dedrick, 2013). However, this group of students often receives limited if any targeted supports in schools because they tend to perform well academically (Suldo, O'Brennan, Storey, & Shaunessy-Dedrick, 2018). To address this gap in literature, this study investigated the efficacy of a targeted intervention in development to support academic and emotional success among students in accelerated curricula, namely the Motivation, Assessment, …

Validating The Construct Of Resiliency In The Health Literacy And Resiliency Scale (Hlrs-Y) With The Child And Youth Resiliency Measure (Cyrm-28), Mercedes N. Cambric

USF Tampa Graduate Theses and Dissertations

Chronic health conditions in youth have increased over the last several decades. It is estimated that within the United States there are between 15% to 18% of youth who are living with a chronic health condition (Centers for Disease Control and Prevention [CDC], 2010). The CDC defines a chronic health condition as an illness that lasts for three months or longer that can be managed, but not cured (CDC, 2010). Although there is some research on youth living with chronic illnesses, there are minimal studies that assess the constructs of health literacy, resiliency, and support/advocacy within this population. The current …

Mitigating Barriers To Chronic Disease Risk Factor Prevention And Management In Disadvantaged Communities, Krys M. Johnson

USF Tampa Graduate Theses and Dissertations

Background: The incidence and prevalence of chronic disease (CD) has increased in recent decades due to the advent of CD management and life-extending technologies. To address this burden on the population and healthcare system, evidence-based CD prevention programs have been developed to reduce the incidence and therefore the prevalence of these diseases. Despite the development and dissemination of effective interventions, African-Americans and Hispanics have disproportionately higher prevalence of CD and associated risk factors and disproportionately lower participation in CD prevention programs. Overweight/obesity and CDs may have intergenerational effects, with overweight adults being more likely to have overweight children who are …

Ethnic Identity As A Protective Factor In Early Adolescent Youth Depression: An Investigation Of Differences By Race And Gender, Leah Bonilla

USF Tampa Graduate Theses and Dissertations

Adolescent mental illness is a major concern in the Unites States. The adolescent stage is a critical developmental period of physical and mental changes, thus it is important to understand protective factors associated with positive wellbeing. The current study aimed to explore: (a) the associations among race, gender, ethnic identity, and depressive symptoms among eighth grade adolescents, (b) to what extent are there differences in degree of depressive symptoms among youth based on race and gender, and (c) to what extent a strong sense of ethnic identity serves as a protective factor against the development of depression among youth with …

Optimizing Early Intervention For Preschoolers' Vocabulary Development, Lindsey A. Peters-Sanders

USF Tampa Graduate Theses and Dissertations

Preschool is a critical time in children’s oral language and pre-literacy skill development, but this development varies greatly among children. Those with smaller vocabularies are at greater risk for developing future language and reading difficulties that persist throughout their education. Because vocabulary knowledge is essential for later reading success, early instruction in preschool is key. To better understand how to enhance preschoolers’ word learning, the current dissertation contains three studies that examined the benefits of explicit vocabulary instruction and identified the factors that best facilitated vocabulary learning among a diverse group of young children. To aid in the early identification …

The Tampa Gym Study: An Ethnographic Exploration Of Gyms, Female Gym-Goers And The Quest For Fitness In Tampa, Fl, Danielle Reneé Rosen

USF Tampa Graduate Theses and Dissertations

The Tampa Gym Study was an ethnographic examination of veteran women exercisers, their workout routines, and their attitudes towards the workouts that they undertake in two Tampa area gyms. The study’s principle objective was to study “fitness culture” in these facilities and the manner in which that culture is embodied in the language women use to describe themselves and their exercise behaviors.

The obesity crisis in the United States has been significantly responsible for an increase in membership in gyms and fitness facilities nationwide. The “culture of fitness” as it is embodied in these facilities has impacted women and their …

Measuring And Understanding Food Accessibility In The Tampa Bay Area, Bailey I. Glover

USF Tampa Graduate Theses and Dissertations

In the Tampa Bay region, increasing population and changing demographics have begun to alter the characteristics of established neighborhoods. An increase in suburban growth has triggered a shift in the location and profitability of food establishments in socially disadvantaged neighborhoods. Supermarket closures have garnered attention from public health officials who are concerned with the overall availability of fresh food throughout Hillsborough and Pinellas Counties. Unfortunately, there has been little research surrounding the quality of food sold at establishments in both the Tampa Bay region and abroad. Instead, many geographic studies have chosen to group both fresh and prepared food establishments …

Habitat Suitability Index Model Of The Florida Sandhill Crane (Grus Canadensis Pratensis) In West-Central Florida, Courtney E. Buck

USF Tampa Graduate Theses and Dissertations

The Florida Sandhill Crane (Grus canadensis pratensis) is a state threatened endemic subspecies of the Sandhill Crane (Nesbitt & Tacha, 1997). With a population that was estimated at a maximum of 5,000 individuals in 2003 (Nesbitt & Hatchitt, 2008), it is imperative to identify potentially viable habitats, as Florida is rapidly developing. This research develops a Habitat Suitability Index model to determine unsuitable to optimally suitable habitat locations throughout west-central Florida. To do so, six suitability variables based on the crane’s life history were evaluated: Potential nesting area, immediate nesting area, wetland coverage, foraging area, brooding area, and road proximity. …

Eating In America: Easing The Transition For Resettled Refugees Through An Applied Anthropological Intervention, Emily A. Holbrook

USF Tampa Graduate Theses and Dissertations

Refugees resettled in the United States are expected to quickly become self-sufficient members of society despite the numerous challenges they face due to adaptation and integration into new systems and ways of life. Issues with dietary and nutritional adaptation persist for resettled refugee communities in the United States and are not prioritized by national, state, or local policy and practice. This research aimed to help mitigate problems with food assistance benefits and healthy eating issues faced by resettled refugees in Hillsborough County through an applied intervention in local English as a Second Language (ESOL) classes. ESOL materials designed to teach …

The Distribution And Biogeochemistry Of Subtropical Intertidal Microbial Mats, Bert D. Anderson

USF Tampa Graduate Theses and Dissertations

Microbial mats have played an important role in the carbon (C) and nutrient cycles since the Archean Eon and modern mats are important contributors to the biogeochemistry of intertidal wetlands. Microbial mats are flat assemblages of microbes that are currently found in many unvegetated habitats globally. Intertidal salt pans are a common habitat for microbial mats, however little is known about the distribution of microbial mats within the intertidal landscape. Understanding the spatial distribution of microbial mats is critical to developing quantitative estimates of the impacts of microbial mats on their ecosystems. We photographically measured the presence and density of …

An Investigation Of The Effects Of The Parasitic Nematode Aplectana Hamatospicula On The Performance And Behavior Of Cuban Treefrogs (Osteopilus Septentrionalis), Kerri Surbaugh

USF Tampa Graduate Theses and Dissertations

Parasitic infections are ubiquitous in nature, and host-parasite dynamics can have powerful effects on wildlife populations. Many species have evolved behavioral responses to infection that can help mitigate damage from parasites. Anorexia is a common response to infection observed throughout the animal kingdom. Reducing nutrient intake can help shift host resources from digestion to immunity, as well as limit resources available to parasites. Reduced feeding can weaken the host, but in some host-parasite interactions, this cost is less than that of maintaining an infection. Here, I describe an experiment aimed to explore the effects of the parasitic nematode Aplectana hamatospicula …

Promoting L2 Idiomatic Competence Among Chinese College Students Via Wechat, Zhengjie Li

USF Tampa Graduate Theses and Dissertations

Many second language (L2) scholars acknowledge that L2 idioms play a critical role in reading development as well as in communicative competence for L2 learners (Arnaud & Savignon, 1997; Barfield & Gyllstad, 2009; Conklin & Schmitt, 2008; Howarth, 1998; Liontas, 2017; Littlemore, Chen, Koester, & Barnden, 2011). Echoing the current trends of Computer Assisted Language Learning (CALL), much research has been done to underscore how L2 idiom learning can be infused with instructional technologies to promote L2 learners’ idiomatic competence (see Luk & Ng, 1998; Nakata, 2011; Yang & Xie, 2013). However, what remains underexplored is the ways that L2 …

USF Tampa Graduate Theses and Dissertations

In Head Start, 28.8% of the children enrolled are Dual Language Learners (DLLs), and 84.4% of those speak Spanish as their home language. However, there are limited studies involving DLLs. Using the Ecological Model of Human Development framework with current revisions with culture as part of the microsystem (Bronfenbrenner, 1994; Vélez-Agosto et al., 2017), the current study aimed to identify maternal level factors that may relate to Latinos' classroom peer play while controlling for classroom quality. Forty-five Latino DLL children attending Head Start, their mothers, and their teachers participated in the study. Head Start administrators provided their most recent vocabulary …

Effect Of Hyperoxia On Type-1 Diabetic Mouse Model, Samuel Ignatious Bolleddu

USF Tampa Graduate Theses and Dissertations

Administration of Hyperoxia (>90 % oxygen) is a pervasive intervention to supplement respiratory needs in patients admitted in ICU/critical care units. Current literature suggests that prolonged use of Hyperoxia therapy is directly associated with in-hospital mortality. The exact reason for this high mortality under Hyperoxia is unknown. Recent explorations in Dr. Panguluri lab identified that dysregulation of Kv channels plays a vital role in the pathophysiology of Hyperoxia-induced pulmonary and cardiac complications using animal models. The proposed research will focus on the part of Hyperoxia in generating cardiotoxicity and ventricular remodeling in the type-1 diabetes patients using the Akita, …

Neuro-Correlates Of Word Processing Among Four-And-Five-Year-Old Children From Homes Varying In Socio-Economic Status, Wendy Olsen

USF Tampa Graduate Theses and Dissertations

A large body of research relates families’ socioeconomic status (SES) to child language development (Hoff & Tian, 2005). Results from these studies indicate preschoolers from low SES backgrounds may have underdeveloped linguistic foundations required for future academic success (Sirin, 2005; Lacouri & Tissington, 2011). These differences have been said to create a 30 million word-gap between the language experiences of low and middle to high SES children by the age of 3 years. Thus, children who come from lower SES backgrounds often lack the vocabulary knowledge used in school and in textbooks (Hart & Risley, 1995). One index of SES …
