This is a multi-method, multi-source, retrospective explanatory study of the implementation factors associated with program installation and partial implementation of an evidence-based violence prevention program, Second Step, in six elementary schools within a large urban school district. The goals of this study were to provide a better understanding of (a) the factors that support implementation of evidence-based programs in K-12 public schools, (b) the factors that constrain implementation, and (c) how developers and researchers might facilitate the application of research …

Prevalence And Influence On Quality Of Life Of Symptoms Caused By Inhaled Odors, Chemicals And Irritants: A Comparison Between Hispanics And Americans, Carmen Perez

USF Tampa Graduate Theses and Dissertations

Efforts to estimate the population prevalence of chemical sensitivities have been limited and have yielded different estimates of the prevalence of affected individuals. Researchers recognize that people differ in their biological susceptibility to environmental contaminants as well as the amount of contaminant to which they are potentially exposed. Lack of information on the population prevalence of people, who report sensitivity to a chemical or many chemicals, as well as variables associated, has been recognized in previous studies (Kreutzer et al., 1999). In a more recent report, Berg et al., in 2007 reported the prevalence and consequences related to inhalation of …

Biotopia: An Interdisciplinary Connection Between Ecology, Suburbia, And The City, Jessica Phillips

USF Tampa Graduate Theses and Dissertations

In an era when cities and towns are changing rapidly, public spaces are the key to reviving civic engagement. By re-introducing these public realms as ecological environments, we can re-structure the organic growth of civic tissue, re-define the city street into a park environment, and reveal the ecological landmarks that once beautified the landscape. These ecological landmarks will be used as corridors, nodes of circulation and storm water management to not only creates a regenerative landscape but to create a connection between ecology, suburbia and the city. The public realm in America has two roles: it is the dwelling place …

To establish the importance of nutraceutical cocrystallization and its use; polyphenols, a major class of nutraceuticals and potential disease preventing agents, are the appropriate targets. The work herein focuses on two polyphenols, protocatechuic acid and quercetin, which …

Depredation And Angler Interactions Involving Bottlenose Dolphins (Tursiops Truncatus) In Sarasota Bay, Florida, Jessica R. Powell

USF Tampa Graduate Theses and Dissertations

Typical depredation behavior by cetaceans involves stealing or damaging prey items already captured by recreational or commercial fishing gear. Depredation among cetaceans has been reported to be increasing in both severity and frequency globally. This behavior is of particular concern for small stocks of cetaceans since any interaction with fishing gear has the potential to injure or kill animals leading to unsustainable losses. In Florida, depredation became evident in 2006 when the number of bottlenose dolphin (Tursiops truncatus) strandings resulting from fishing gear ingestion or entanglement sharply increased. For the resident dolphin community in Sarasota Bay, modeling showed continued mortalities …

Experience + Evolution: Exploring Nature As A Constant In An Evolving Culture And Building Type, Robin Plotkowski

USF Tampa Graduate Theses and Dissertations

Throughout time, our natural environment has been one of the only constants in our evolution. While cultures change and evolve, nature's beauty and positive effects on humans have always been present. Unfortunately, our built environment has generated much attention for its profound impact on our natural environment. Buildings in the United States consume a third of our total energy use, raw material use, and waste output, not to mention the negative effects they can have on our well-being, economy, health and productivity. In an effort to protect our natural environment, our built environment must become more responsible to the environment …

Costa Rica has been a popular tourist destination for decades, and is currently the second largest industry in the country. With so many tourists coming into the country, Costa Rica provides a rich environment within which to examine sex tourism. Costa Rica is a known destination for male sex tourists hoping to experience legal prostitution or child prostitution. Although it is lesser known, female sex tourism also occurs in Costa Rica. Female sex tourism occurs in the form of pseudo-romantic relationships between female tourists and Costa Rican men working in the tourist industry. These people spend a great deal of …

Nature, Daylight And Sound: A Sensible Environment For The Families, Staff And Patients Of Neonatal Intensive Care Units, Ana Praskach

USF Tampa Graduate Theses and Dissertations

In healthcare environments, elements like nature, daylight and sound have been found to significantly influence the healing process of patients, by enhancing the quality of their recovery, shortening their hospital stay and consequently reducing hospital costs. For instance, it has been shown that exposure to nature triggers positive responses in people, daylight affects human psychology, and different sounds have varying behavioral effects on different groups of people. But, while these effects have been carefully studied in adult patients, leading to clear design standards, less is known about their impact on premature infants. Interestingly, the care that many newborns receive in …

From The Academy To The Streets: Documenting The Healing Power Of Black Feminist Creative Expression, Tunisia L. Riley

USF Tampa Graduate Theses and Dissertations

I explore through feminist content analysis how poetry, blogging, political narrative, and music are employed by Black women as a means of personal and political empowerment, healing, activism and feminist practice. I theorize the emergence of a new manifestation Black feminism represented in poetry, blogs, political narrative, and popular music-exploring its ties to the history of Black feminism. I seek to demonstrate how gender conscious Black women create poetry, blogs, political narratives, and music as the catalyst to spark anti-sexist activism in contemporary Black women who may or may not call themselves feminists.

Agriculture And Tampa Bay News: How Do Local News Media Frame Agribusiness?, Alex R. Ritzheimer

USF Tampa Graduate Theses and Dissertations

The purpose for this thesis was to explore a dynamic between the news media, their subjects, and their audience. I investigate whether everyday news media frame the information they deliver in such a way as to potentially direct the audience on how to respond to news stories. The setting for this research question is in the Tampa Bay area of Florida and the subject matter deals specifically with agriculture, its practitioners, how they do business, and how the local news media report about it. The issue will be explored from an applied anthropological perspective, basing conclusions on field research and …

Assessing Druze Identity And Strategies For Preserving Druze Heritage In North America, Chad Kassem Radwan

USF Tampa Graduate Theses and Dissertations

This research study focuses on promoting historical, religious, and cultural knowledge among transnational Druze. The Druze are a relatively small, tightly knit religious community from the Middle East who practice endogamy and accept no converts. In the diaspora, Druze have often established their own communities based on their collective ancestral and familial ties and through the establishment of groups such as the American Druze Society. This study works to allow individuals to discuss their Druze identity, identify the community's social problems, and recommend possible approaches or solutions. My research experience as an insider doing ethnography among fellow Druze has in …

Psychosocial Outcomes Of Weight Stigma Among College Students, Sabrina Joann Robinson

USF Tampa Graduate Theses and Dissertations

Overweight and obesity are important public health issues in the United States with more than 60% of US adults overweight or obese. The social consequences of being overweight and obese are serious and pervasive. Individuals who are overweight and obese are often the targets of bias and stigma and thus susceptible to negative attitudes. Obesity and weight stigma have been linked to low self-esteem, higher rates of depressive symptoms, body dissatisfaction and poor psychological adjustment. Although weight stigma is a problem in the general population, it is more consequential among adolescents due to mental and physical developmental changes. Therefore college …

Predictors Of Cancer Caregiver Depression Symptomatology, Henry R. Rivera

USF Tampa Graduate Theses and Dissertations

While the duration of the cancer illness may be shorter than that of other serious diseases, such as Alzheimer's disease, cancer caregivers provide many more hours of care during a week. Research directed at the intensive experience of caregiving of hospice cancer patients is needed as there is limited research of predictors of hospice cancer caregiver depression symptomatology. The purpose of the study was to examine predictors of depression symptomatology in caregivers of hospice cancer patients. A secondary analysis was conducted using baseline assessment data of patients and caregivers from a larger study of patient/caregiver dyads from two large hospices …

The Role Of Proactivity During Organizational Entry: Proactive Socialization Tactics, Citizenship And Counterproductive Work Behaviors, Ozgun Burcu Rodopman

USF Tampa Graduate Theses and Dissertations

Newcomers engage in proactive behaviors during organizational entry to increase their adjustment to the organization and to successfully complete their socialization. The present study investigated the links between proactive socialization tactics (i.e., positive framing, sense making and relationship building) and organizational outcomes. Specifically, organizational citizenship behaviors (e.g., assisting coworkers) and counterproductive work behaviors (e.g., verbal abuse) were investigated. The sample included 216 employees from various industries and organizations with an average organizational tenure of 9 months. The results indicated that all proactive socialization behaviors were associated with high levels of citizenship behaviors (i.e., OCB). Only positive framing was associated with …

Evolution Of A Conserved Gene Regulatory Network Among Echinoderms: A Comparison Of Genes Expressed In The Skeletogenetic Lineage Of The Ophuroid Ophiocoma Wendtii And The Echinoid Strongylocentrotus Purpuratus, Mitch James Ruzek

USF Tampa Graduate Theses and Dissertations

One of the most fundamental and critical functions of embryological development is the control and regulation of differential genes and gene networks. The study of the gene networks involved in development is a mechanism for understanding the developmental process at its most basic level. An evolutionary change in a morphological feature or features must depend on a reorganization or co-option of one or more developmental gene regulatory network just as retention of an ancestral morphological trait must rely on retention of a common gene regulatory network. Studying two closely related classes in the same phylum with the same essential morphological …

Relationships Between Participation In Athletics And Substance Use Among School Students, Kevin M. Stockslager

USF Tampa Graduate Theses and Dissertations

Substance use among high school students has become an increased concern for administrators, parents, and community members. Previous research has demonstrated relationships between adolescent substance use and numerous negative outcomes. This study investigated the relationship between athletic participation and substance use using self-report data from a sample of 139 high school students. Specifically, the current study examined the relationship between frequency and setting of participation in athletic activities (e.g., football, baseball, soccer) and multiple types of substance use (e.g., alcohol, tobacco, marijuana, other illicit drugs) in adolescents. The results of this study indicate that nonathletes reported significantly more marijuana use …

Characterization Of Nprc And Its Binding Partners, Abdel A. Alli

USF Tampa Graduate Theses and Dissertations

The C type natriuretic peptide receptor (NPRC) also known as NPR3 is a widely expressed single transmembrane-spanning protein. NPRC functions as a homodimer at the cell surface for the metabolic clearance of a broad range of natriuretic peptides from circulation. The intracellular domain of NPRC is coupled to inhibitory G proteins and is involved in mediating signal transduction. In order to further elucidate the role of NPRC in signal transduction a proteomic approach was taken to identify putative protein binding partners for NPRC in different cell-types. An interrogation of the molecular association between NPRC and its identified protein binding partner(s) …

The Importance Of Benthic Habitats As Reservoirs Of Persistent Fecal Indicator Bacteria, Brian D. Badgley

USF Tampa Graduate Theses and Dissertations

Enterococci are fecal indicator bacteria (FIB) that are used worldwide for water

quality assessment. However, evidence of high densities and extended survival of

enterococci in sediments and submerged aquatic vegetation (SAV) has caused uncertainty

about their reliability in predicting human health risks from recreational activities in

environmental waters. To address the concern that sediments and SAV may harbor large

reservoirs of enterococci that can affect water column concentrations, aquatic mesocosms

and environmental sampling were employed to investigate patterns of enterococci

densities and population structure across the Tampa Bay watershed.

In mesocosm experiments and environmental samples, SAV harbored higher

densities of …

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to uncover the perspectives that pertain to the literacy experiences of young Hispanic boys. Hispanic boys will be asked to describe, feel, judge, and make sense of their public and private literacies (Faulkner, 2005). This phenomenological study embraces two methods of data collection, participant focus groups and individual interviews. The primary question guiding this inquiry was: What are the perceptions of adolescent Hispanic boys who are considered low level readers (by state achievement tests) regarding their literacy experiences?

In order to help provide background information and set the stage for future work when considering …

Naturalism In The Philosophies Of Dewey And Zhuangzi: The Live Creature And The Crooked Tree, Christopher C. Kirby

USF Tampa Graduate Theses and Dissertations

This dissertation will compare the concept of nature as it appears in the philosophies of the American pragmatist John Dewey and the Chinese daoist Zhuangzi (Chuang Tzu) and will defend two central claims. The first of these is that Dewey and Zhuangzi share a view of nature that is non-reductive, philosophically liberal, and more comprehensive than the accounts recurrent in much of the Western tradition. This alternate conception of nature is non-reductive in the way that it avoids the physically mechanistic outlook underwriting much of contemporary Anglo-American thought. It is philosophically liberal in that it accepts a more generous and …

Sharing The Power Of Words And Changing Lives Through College-Level Instruction In Grammar And Mechanics, Carol Ann Tillema

USF Tampa Graduate Theses and Dissertations

Intrigued by the English language and its far-reaching applications worldwide as a standard means of communication, I begin my disquisition with a focus on the meaning and derivation of grammar and its place in the trivium of ancient and modern study. I stress the need to reemphasize college-level instruction in grammar and mechanics as a complement to rhetoric and logic by studying and teaching editing, which involves semantics, syntax, phonology, morphology, conventions, mechanics (spelling, punctuation and format), in writing centers and classrooms. Noting growing nationwide illiteracy, I research the pedagogies and writing of experts in the field of rhetoric and …

The Provision Of Spousal Support: Antecedents, Consequences, And Crossover Effects, Jay M. Dorio

USF Tampa Graduate Theses and Dissertations

The present study had four main objectives. First, the relationship between the provision of spousal support and its theoretical antecedents and consequences was assessed as informed by the conservation of resources theory (Hobfoll, 1989). Second, the crossover of physicians' work interference with family conflict on their spouses' family demands (perceived family demands and family hours) was investigated. Next, the mediating role of social support as an explanation for the crossover process was examined using two distinct pathways. Lastly, the fourth objective of the present study was to investigate the relationships described above across multiple time points and using dual-source data …

Redefining What Is Sacred, Sarah A. Sisson

USF Tampa Graduate Theses and Dissertations

Within the last twenty years, Evangelical Protestants, primarily in the southeastern United States, transformed the functions of their churches from a traditional sacred gathering space to an open outreach resource for the community. Architectural form did not follow these new functions and the complexity of their modern spatial usage has never been resolved. Modern typologies, such as the mega-center or its smaller counter-part the metal building chapel, ignore their responsibility to the community as a symbolic presence.

Protestant churches began community outreach programming like life wellness series and youth enrichment programs. Once viewed as secular, these programs increased accessibility of …

Development Of Novel Biocompatible Hydrogel Coatings For Implantable Glucose Sensors, Chunyan Wang

USF Tampa Graduate Theses and Dissertations

Due to sensor -tissue interactions, currently none of the commercially available glucose sensors are capable of continuous, reliable monitoring of glucose levels during long-term implantation. In order to improve the lifetime of implanted glucose sensors, two series of biocompatible novel hydrogel coatings were designed, synthesized and the physical properties were measured.

Different hydrogels with various 2,3-dihydroxypropyl methacrylate (DHPMA) compositions were coated onto glucose sensors. Results show that the higher freezable water content, swelling rate and uniform porosity that resulted from high DHPMA content increased the sensitivity and shortened the response time of glucose sensors. The linear range of a glucose …

Determination Of Decay Rates And Differential Survival Of Escherichia Coli And Enterococcus Spp. Strains Under Hydrodynamically Active Conditions Using Box-Pcr Typing, Phoebe West Koch

USF Tampa Graduate Theses and Dissertations

Indicator organisms (IOs) such as Escherichia coli and Enterococcus spp. are used to predict the presence of pathogens in waters. Determining the relationships between environmental factors, IOs, and pathogens is a key to assessing water quality and ensuring public health, yet certain strains of E. coli and Enterococcus spp. survive for long periods in natural waters. Molecular subtyping, using repetitive extragenic palindromic DNA sequences (BOX-PCR), has been used to discriminate among environmental E. coli and Enterococcus spp. isolates. The reproducibility of BOX-PCR patterns varies with DNA purification methods; therefore, it is important to develop a standardized, rapid, high throughput DNA …

Linking Health Hazards And Environmental Justice: A Case Study In Houston, Texas, Marilyn Marie Williams

USF Tampa Graduate Theses and Dissertations

This dissertation seeks to extend quantitative research on environmental justice and address methodological limitations of previous studies by: (a) using new indicators of exposure to air pollution and contemporary risk modeling techniques; (b) assessing disparities in human health risks, instead of focusing only on potential exposure or proximity to pollution sources; and (c) using multivariate regression models that consider the effects of spatial dependence. The case study examines racial/ethnic and socioeconomic disparities in the geographic distribution of exposure to airborne toxic emissions from industrial point sources in the Houston-Galveston-Brazoria metropolitan statistical area. Industrial pollution sources for this study comprise facilities …

Architectural Strategies In Reducing Heat Gain In The Sub-Tropical Urban Heat Island, Mark A. Blazer

USF Tampa Graduate Theses and Dissertations

Most scientists agree that the earth's temperature continues to rise. The heat gain is more pronounced in urban areas due to a phenomenon known as the urban heat island effect. The urban heat island effect is a seemingly inevitable result of urban development, which has far reaching consequences. With energy costs skyrocketing and the destruction of the environment at risk, urban structures and buildings must do more to make our urban settings more environmentally friendly.

So far, there are two well known ways to combat these effects. First, the heat island can be slightly be negated by adding well-watered vegetation …

An Address, Not A Room Number: An Assisted Living Community Within A Community, Gregory J. Novotnak

USF Tampa Graduate Theses and Dissertations

As the son of parents of the "baby boomer" generation I foresee the immanent increased demand for assisted living for the elderly. By 2030 an estimated 20 percent - one in five Americans - will be 65 or older. Unless attention is paid now to advancing the designs and opportunities for assisted-living, there will either be a distinct lack of available options, or worse, the continuation of out-dated designs that simply will not be a marketable.

Contemporary thinking with regard to the design of places of residence for the elderly has changed dramatically from the days of outdated structures and …
