Remote Sensing And Spatial Metrics For Quantifying Seagrass Landscape Changes: A Study On The 2011 Indian River Lagoon Florida Seagrass Die-Off Event, René Dieter Baumstark

USF Tampa Graduate Theses and Dissertations

Florida’s seagrasses are ecologically important marine environments which have suffered major degradation caused by increasing anthropogenic pressures. A 2011 seagrass die-off event caused by an algal bloom in the Florida Indian River Lagoon (IRL) was particularly severe with a majority of seagrass lost in areas such as the Banana River. An understanding of how this coastal marine environment changed is an important step toward better managing resources for conservation. Modern tools and methods provide new opportunities to study these changes at the landscape scale, a scale that informs on the larger more comprehensive state of a system. Classified satellite imagery …

Transition Of Persons With Developmental Disabilities From Parental To Sibling Co-Residential Care: Effects On Sibling Caregiver Well-Being And Family Functioning, Richard Steven Glaesser

USF Tampa Graduate Theses and Dissertations

Comprehensive improvements in medical care, technology and residential settings have resulted in persons with developmental disabilities (DD) advancing to older age and outliving parental caregivers (Heller & Arnold, 2010). Typical siblings are expected to become the primary caregiver to their sibling with DD when parents become ill or die and unable to provide care (Burke, Fish, & Lawton, 2015; Heller & Arnold, 2010). This dissertation looks at the wellbeing and family functioning of siblings who become the co-residential caregiver following the transition of a brother or sister with DD from parental to sibling co-residential care. The family systems framework was …

Operationalizing The Pressure And Release Theoretical Framework Using Risk Ratio Analysis To Measure Vulnerability And Predict Risk From Natural Hazards In The Tampa, Fl Metropolitan Area, Jessica A. Wilder

USF Tampa Graduate Theses and Dissertations

Significant damage and loss is experienced every year due to natural hazards such as hurricanes, tornadoes, droughts, floods, wildfires, volcanoes, and earthquakes. NOAA’s National Center for Environmental Information (NCEI) reports that in 2016 the United States experienced more than a dozen climate disaster events with damages and loss in excess of a billion dollars (NOAA National Centers for Environmental Information, 2017). Identifying vulnerabilities and risk associated with disaster threats is now a major focus of natural hazards research.

Understanding The Effects Of Demographic And Socio-Economic Factors On Public Transit Ridership Trends, Kurt Lehmann

USF Tampa Graduate Theses and Dissertations

Public transit, an important mobility service for many, has incurred ridership decline in the U.S. for the past three years. In 2014, U.S. transit ridership was 10.74 billion unlinked passenger trips. In 2015, total ridership was 1.0 percent fewer, and the 2016 decrease was 2.2 percent from 2015. The consistent abandonment of transit in the U.S. does not seem to be ending. In 2017, ridership predicted from year-to-date data is 2.4 percent less than 2016. Furthermore, per capita ridership has decreased 17 percent since 1980. Both the short-term ridership trend and long-term per capita ridership trend is concerning given the …

Food Insecurity And Age Of Menarche: Using A Biocultural Approach And Life History Theory To Assess Risks Of Food Insecurity Among Girls In Tampa Bay, Fl, Mecca Burris

USF Tampa Graduate Theses and Dissertations

Using life-history theory within a biocultural perspective, this research explores whether household food insecurity correlates with early or delayed menarche among adolescent females in Tampa Bay, Florida. Early onset of puberty and menstruation is connected with numerous health consequences including growth stunting, obesity, type-2 diabetes, adult-onset asthma, reproductive cancers, increased risk for depression, behavioral problems, and early sexual activity which increases the risk for STIs and ovarian cancer. Early menarche also seems to disproportionally impact disadvantaged and minority groups. While there are many known factors that influence age at menarche (e.g.: genetics, diet), little is understood regarding the effect of …

Reconstructing Historical Hurricane Tracks In The Atlantic Basin: Three Case Studies From The 1840s, Emily L. Cerrito

USF Tampa Graduate Theses and Dissertations

Analyzing past tropical cyclone activity enables researchers to recognize patterns of hurricane variability, estimate hurricane return periods, and assess local risk to future storms. This paleotempestology study used original primary data to make the historical record as comprehensive and accurate as possible for three major hurricanes: October 1844, October 1846, and September 1848. This thesis presents the reconstructed storm tracks, assesses the societal impacts, and evaluates the storm intensity of these three major hurricanes for the eastern U.S. and Cuba. The data utilized in this study include ship logbooks, newspapers, diaries, and instrumental meteorological records. A geographic information system (GIS) …

Policing The Riverfront: Urban Revanchism As Sustainability, Jared J. Austin

USF Tampa Graduate Theses and Dissertations

An unnoticed shift is underway in the revanchist model of accumulation by dispossession (Harvey, 2005) that is rebranding the neoliberal reorganization of space and economic growth. I call this shift “Urban Revanchism as Sustainability,” following Mike Davis and Daniel Monk (2007). In this study, I describe how Tampa elites, led by Democratic Mayor Bob Buckhorn, use politically popular discourses of ‘sustainability’, ‘walkability’, ‘bike-ability’, among others, to coopt the rhetoric and symbols of social and environmental justice as cover for urban capital accumulation. I describe how in the wake of 2008 which devastated Tampa, and in the context of the subsequent …

The Promised Body: Diet Culture, The Fat Subject, And Ambivalence As Resistance, Jennifer Dolan

USF Tampa Graduate Theses and Dissertations

Since the turn of the twentieth century, middle-class Americans have considered the thin body--ostensibly the result of self-control and self-discipline--a moral imperative and a symbol of good citizenship. In this thesis, I provide a critical perspective on fat studies by examining the ways in which the field authorizes itself in a society that deems the fat body unhealthy, costly, and immoral. As one potential solution to fat-hatred, fat studies proposes fat-positivity, but I argue that fat-positivity requires an extraordinary act of imagination in which the fat person overcomes what I term the ideology of thinness and subsequently feels good about …

Angiostrongylus Cantonensis: Epidemiologic Review, Location-Specific Habitat Modelling, And Surveillance In Hillsborough County, Florida, U.S.A., Brad Christian Perich

USF Tampa Graduate Theses and Dissertations

Angiostrongylus cantonensis is a parasitic nematode endemic to tropical and subtropical regions and is the leading cause of human eosinophilic meningitis. The parasite is commonly known as rat lungworm because the primary host in its lifecycle is the rat. A clinical overview of rat lungworm infection is presented, followed by a literature review of rat lungworm epidemiology, risk factors, and surveillance projects. Data collected from previous snail surveys in Florida was considered alongside elevation, population per square kilometer, median household income by zip code territory, and normalized difference vegetation index specific to the geographic coordinates from which the snail samples …

Bayesian Inference On Quantile Regression-Based Mixed-Effects Joint Models For Longitudinal-Survival Data From Aids Studies, Hanze Zhang

USF Tampa Graduate Theses and Dissertations

In HIV/AIDS studies, viral load (the number of copies of HIV-1 RNA) and CD4 cell counts are important biomarkers of the severity of viral infection, disease progression, and treatment evaluation. Recently, joint models, which have the capability on the bias reduction and estimates' efficiency improvement, have been developed to assess the longitudinal process, survival process, and the relationship between them simultaneously. However, the majority of the joint models are based on mean regression, which concentrates only on the mean effect of outcome variable conditional on certain covariates. In fact, in HIV/AIDS research, the mean effect may not always be of …

Understanding The Linkages Between Urban Transportation Design And Population Exposure To Traffic-Related Air Pollution: Application Of An Integrated Transportation And Air Pollution Modeling Framework To Tampa, Fl, Sashikanth Gurram

USF Tampa Graduate Theses and Dissertations

Rapid and unplanned urbanization has ushered in a variety of public health challenges, including exposure to traffic pollution and greater dependence on automobiles. Moreover, vulnerable population groups often bear the brunt of negative outcomes and are subject to disproportionate exposure and health effects. This makes it imperative for urban transportation engineers, land use planners, and public health professionals to work synergistically to understand both the relationship between urban design and population exposure to traffic pollution, and its social distribution. Researchers have started to pay close attention to this connection, mainly by conducting observational studies on the relationship between transportation, urban …

Full-Time Teleworkers Sensemaking Process For Informal Communication, Sheila A. Gobes-Ryan

USF Tampa Graduate Theses and Dissertations

Organizations have traditionally accomplished connectivity among their workers by co-locating them in shared organizational workplaces. However, information and communication technologies (ICTs) are offering alternative ways to accomplish this kind of connection. This change raises important questions about what it is possible to accomplish through such mediated communicative connections, and if there are work activities that are best accomplished face-to-face. Practitioners and researchers have historically identified informal communication as a process essential to organizational success that is difficult or impossible to accomplish outside of shared physical environments. This study documents the ways full-time teleworkers are accomplishing informal communication without being in …

The Common Core State Standards And The Elementary Social Studies Curriculum: A Case Study Of Teacher Perceptions In Florida, Kacie M. Nadeau

USF Tampa Graduate Theses and Dissertations

The most recent phase of curriculum reform in the era of accountability is the Common Core State Standards (CCSS) which have essentially reshaped the landscape of public education. Its objective of preparing K-12 students for college and career upon high school graduation have prioritized English language arts, mathematics, and science over social studies, which is not part of widespread high-stakes testing for elementary students. This qualitative case study investigated eleven intermediate elementary teachers’ perceptions of alignment between CCSS and the elementary social studies curriculum. Data gathering analysis included two semi-structured interviews and an archival analysis of the mandated curriculum. The …

USF Tampa Graduate Theses and Dissertations

The objective of this study is to address some important questions associated with stomach cancer patients using the data from the Surveillance Epidemiology and End Results (SEER) program of the United States. To better understand the behavior of stomach cancer, we first perform parametric analysis for each patient group (white male, white female, African American male, African American female, other male and female) to identify the probability distribution function which can best characterize the behavior of the malignant stomach tumor sizes. We evaluate the effects of patients’ age, gender and race on the malignant stomach tumor sizes by developing quantile …

Reef Fish Biodiversity In The Florida Keys National Marine Sanctuary, Megan E. Hepner

USF Tampa Graduate Theses and Dissertations

The biological diversity of reef-fish in the Florida Keys National Marine Sanctuary (FKNMS) from 1999 – 2016 was evaluated in terms of abundance, biomass, species richness, evenness, Shannon diversity, Simpson diversity, and functional diversity, using observations collected by multiple agencies and institutions under the Reef Visual Census (RVC) program. To compare the different diversity indices species richness, Shannon diversity, Simpson diversity, and functional diversity were converted into effective number of species. I examined the seven indices by no-take marine zones, in seven benthic habitat strata, and across the three-distinct geographic subregions in the Florida Keys domain (Upper, Middle, and Lower …

Surveilling Hate/Obscuring Racism?: Hate Group Surveillance And The Southern Poverty Law Center's "Hate Map", Mary Mckelvie

USF Tampa Graduate Theses and Dissertations

In what ways does the legal and political monitoring of “hate groups” and "hate group activities" benefit the American left? Possible victims of crimes? Law enforcement? The state? Specifically, in what ways does the Southern Poverty Law Center’s “hate map” challenge and/or reiterate relations of power and knowledge? This thesis offers a feminist critical analysis of hate group surveillance and the Southern Poverty Law Center’s mapping of hate. The Southern Poverty Law Center (SPLC) is a progressive legal advocacy group that aids in the surveillance of “hate groups” and legislation against “hate crimes.” I investigate the assumptions grounding the SPLC’s …

Perceptions Affecting Tree Valuation: An Analysis Of Recently Sold And Leased Properties In Tampa, Florida, Cody R. Winter

USF Tampa Graduate Theses and Dissertations

The urban forest is a structure that is fluid in both species composition and how it is integrated in our cities and suburban areas. Much like the fluidity in its structure, the urban forest provides ecosystem services and disservices in many forms. These services and disservices can often come in the form of temperature regulation, lower crime rates, and even higher property values. The latter, which is associated with the economic value of trees, is a part of the hedonic pricing literature which suggests that there is a disparity in the value associated with trees to house prices. With the …

Smog Pollution In China: News Framing And Issue-Attention Cycle Per The, Yingying Zhang

USF Tampa Graduate Theses and Dissertations

China's smog air pollution has become an increasingly urgent environmental crisis in China. Using framing as theoretical framework, this research examined how much media attention is focused on smog air pollution and how print media frame smog air pollution. An empirical content analysis of 339 articles in the People’s Daily newspaper was conducted from 2000 to 2016, and the results showed that “non-voluntary solutions” and “problem” frames were the two frames that had been most utilized to construct stories about air pollution. Smog air pollution crisis also discussed in terms of Downs issue-attention cycle, a five-stage model explaining the rise …

The Role Of High-Elevation Headwater Runoff In Streamflow Generation And Water Supply In The Northern Andes, Colombia, Laura Lotero Lozano

USF Tampa Graduate Theses and Dissertations

Water security requires that sufficient quantities of water be available at critical times. This is particularly challenging for high-intensity urban and agricultural settings. In underdeveloped nations, streamflow is commonly the preferred water source, as it is readily available and delivered cost-free to users. Yet, the sources of these critical streamflows are often unknown. This issue is salient in the Northern Andes, where basic knowledge of controlling factors for the quantity, quality, and timing of runoff is lacking. High-elevation headwaters are the primary catchment areas in the Northern Andes, but the extent of water providing to municipalities in the Northern Andes …

Grassroots Branding: An Exploration Of Grassroots Businesses Within The Florida Skateboard Community, Lawrence M. Shaw

USF Tampa Graduate Theses and Dissertations

Why do original/grassroots branding efforts occurring on a local level continue to proliferate despite the existing market saturation created by larger corporate entities? Using existing theoretical frameworks associated with “do it yourself” (DIY) culture, this thesis explores cultures and themes associated with skateboarding, including the production and consumption of brands of skateboarding products; the use of space and spatiality by skateboarders; and, finally, changes in skateboarding. I conducted ethnographic interviews within a network of skateboard entrepreneurs in the Florida skateboard community, seeking to understand why they start brands, their perceptions of their entrepreneurial efforts, and how these businesses operate. Drawing …

Exploring The Facilitators And Barriers Of Cognitive Engagement Among Ninth Grade Students In Accelerated Curricula, Kai Zhuang Shum

USF Tampa Graduate Theses and Dissertations

Cognitive engagement has been linked to positive outcomes such as academic achievement (Eccles & Wang, 2012). However, students’ level of cognitive engagement tend to decline as students move into middle childhood and adolescence (Archambault, Janosz, Morizot, & Pagani, 2009; Wang & Eccles, 2012a; Wiley & Hodgen, 2012). In addition, two out of three high school students nationwide reported feeling bored at school because the academic tasks are not interesting or relevant (Yazzie-Mintz, 2006). In regard to this matter, researchers have examined factors that relate to cognitive engagement. Most of the existing research is quantitative in nature and only involves students …

Re-Placing The Plantation Landscape At Yulee’S Margarita Plantation, Katherine M. Padula

USF Tampa Graduate Theses and Dissertations

U.S. Senator David Levy Yulee’s Margarita sugar plantation flourished from 1851 to 1864 in Homosassa, Citrus County, Florida. The plantation was abandoned in 1864 and memory of its precise location slowly faded, as the physical evidence of its existence deteriorated. Today, the only plantation structure known to be still standing is the sugar mill, preserved as part of the Yulee Sugar Mill Ruins Historic State Park (CI124B). The remainder of the plantation, including its boundaries, remains unknown. Perhaps at least partly owing to this absence, the mill’s interpretive signage provides an unfortunate univocal historical interpretation of the site and lacking …

Sustainability Of Community-Managed Rural Water Supply Systems In Amazonas, Peru: Assessing Monitoring Tools And External Support Provision, Jacob E. Mangum

USF Tampa Graduate Theses and Dissertations

Globally, there is still a large number of people without access to safe drinking water; a known health risk. In rural areas of countries like Peru, when potable water systems are built the responsibility for maintaining these systems is given to volunteer water committees. Despite its prevalence as a management model, there is a consensus that community management alone cannot ensure sustainable water service. Therefore, the overall goal of this research is to assess the sustainability of community-managed water systems in rural areas of the department of Amazonas, Peru. Specifically, this research examines two mechanisms that have been shown to …

Determinants Of Tipping Rates: New Findings And Extensions, Christopher Carl Olson

USF Tampa Graduate Theses and Dissertations

There is a movement underway to eliminate the practice of tipping restaurant servers that is gaining momentum (Goldberger, 2015). In lieu of gratuities, restaurants are simply raising menu prices or assessing a service charge and paying servers a fixed hourly wage (Kummer, 2016). Before restaurateurs can adopt such a strategy, they need to thoroughly understand the factors that affect tipping behavior in order to develop meaningful fixed wage rates that do not diminish service levels or employee morale. The first step in this process is a better understanding of the determinants of tipping rates.

The existing research has identified many …

A Study On The Efficacy Of The Medicare Bundled Payments For Care Improvement Initiative At A Large Community Hospital In The Southeast United States, Elizabeth E. Kerns

USF Tampa Graduate Theses and Dissertations

In 2013, Medicare launched the Bundled Payments for Care Improvement (BPCI) Initiative which linked payments for multiple services for a complete episode of patient care. With this innovative reimbursement model, hospitals accepted fixed target payments for certain types of clinical diagnoses that were intended to support better care coordination and better outcomes for patients at lower cost to Medicare. This was one of many programs aimed at addressing the serious challenges facing United States healthcare, including costs that are skyrocketing to unsustainable levels and lack of coordination of care across venues.

Preliminary Medicare results showed that bundled payments might lead …

Freshwater Wetland Creation In A Changing Urban Environment: Designing For Long-Term Viability, Aaron Thomas Ryan Brown

USF Tampa Graduate Theses and Dissertations

Urbanization and wetland mitigation are increasingly common in coastal watersheds with expanding populations. These mitigation wetlands are intended to offset the functional and structural losses experienced when natural systems are degraded or destroyed. In the Tampa Bay watershed, urbanization is both expanding into the upper reaches of the watershed and intensifying in previously-developed areas, resulting in the creations of hundreds of freshwater mitigation wetlands. This dissertation utilized an existing database of mitigation wetlands, publicly available data, and field surveys to investigate the relationship between constructed wetlands and their surroundings and also determine how design affects wetland condition over time. The …

Perspectives Of Ap U.S. History Teachers In Title I Schools, Mark Lance Rowland

USF Tampa Graduate Theses and Dissertations

The College Board’s Advanced Placement (AP) Program continues to expand annually with increased numbers of high school students nationwide enrolling in AP courses and taking end-of-course AP exams, in hopes of earning college credit and strengthening high school transcripts. As the College Board promotes increased minority student participation (specifically African-American and Hispanic students) in AP courses, AP teachers face new challenges as potential first-generation college students enter their classrooms with below-level reading scores and a lack of essential critical-thinking skills needed for college-level assessment.

The participants in this study are five AP U.S. History Teachers from urban, suburban, and rural …

Trade, Interaction And Change: Trace Elemental Characterization Of Maltese Neolithic To Middle Bronze Age Ceramics Using A Portable X-Ray Fluorescence Spectrometer, Frederick S. Pirone

USF Tampa Graduate Theses and Dissertations

The insular nature of the Maltese archipelago provides a unique opportunity to explore trade and cultural change from the Neolithic to the Bronze Ages in the central Mediterranean. I hypothesize that, during the period in which the Maltese islands were experiencing a form of isolation—owing either to their distance from Sicily and other populated regions, to the collective formation of an inwardly-focused culture, or to a combination of these factors—it is unlikely that pottery played a significant role as either an import or export in the archipelago’s exchange relationships with other communities in the central Mediterranean. I accordingly propose that …
