Understanding The Relationship Between Informal Interactional Diversity And Males’ Engagement In The Undergraduate Experience, Amanda Cutchens

USF Tampa Graduate Theses and Dissertations

The diversity of the undergraduate student population encourages understanding of others and provides opportunities for students to challenge their assumptions of cultures, political and religious views, values, and personal backgrounds. However, it also creates challenges for academic and student success as faculty and administrators struggle to meet different generational and cultural needs. A broader, more inclusive definition of student success may help meet the needs of a more modern complex institutional student demographic. It may also allow for new avenues of research specifically related to success for Black, Hispanic, and White undergraduate male students, as these students continue to struggle …

USF Tampa Graduate Theses and Dissertations

Grounded in framing theory, this thesis presents a qualitative content analysis of newspaper coverage of genetically modified foods by two Chinese newspapers- People’s Daily and Southern Metropolis, in 2000-2017. The political, economic, public opinion and legal implications involved have made the reports of genetically modified (GM) foods present different framing, themes, and positions between People’s Daily and Southern Metropolis. This study aims to examine the various frames used in the coverage of GM foods in two major Chinese newspapers that operate within different media frameworks.

Results of the content analysis illustrated that significant differences existed in the newspapers in …

Thermodynamic And Kinetic Aspects Of Hen Egg White Lysozyme Amyloid Assembly, Tatiana Miti

USF Tampa Graduate Theses and Dissertations

Deposition of protein fibers with a characteristic cross-β sheet structure is the molecular marker associated with human disorders ranging from Alzheimer's disease to type II diabetes and spongiform encephalopathy. Given the large number of non-disease related proteins and peptides that have been shown to form amyloid fibrils in vitro, it has been suggested that amyloid fibril formation represents a generic protein phase transition. In the last two decades it has become clear that the same protein/peptide can assemble into distinct morphologically and structurally amyloid aggregates depending on the solution conditions. Moreover, recent studies have shown that the early stage, oligomeric …

Cultivating Peace Via Language Teaching: Pre-Service Teachers' Beliefs And Emotions In An Efl Argentine Practicum, María Matilde Olivero

USF Tampa Graduate Theses and Dissertations

In order to understand the intricate processes involved in second language teacher development, in the last decade studies in second language teacher education (SLTE) have addressed the need to explore pre-service teachers’ beliefs and emotions jointly as they occur in their contexts of teaching. SLTE researchers have referred to the importance of helping pre-service teachers verbalize their beliefs and try to understand and regulate their emotions as they can serve to explain what, how, and why pre-service teachers do what they do during their practicum experience. In addition, considering future teachers will be passing on their beliefs, values, and ways …

Genetic Identification And Population Characteristics Of Deep-Sea Cephalopod Species In The Gulf Of Mexico And Northwestern Atlantic Ocean, Amanda Sosnowski

USF Tampa Graduate Theses and Dissertations

Nearly all deep-sea cephalopod life history studies have been completed by examination of specimens collected in the wild. Much of this work is like piecing together a puzzle; knowledge of the life history of many species remains fragmented and hence, taxonomically and phylogenetically confused. Molecular approaches and sequencing technologies are powerful tools for deciphering wild-type cephalopod life history and population dynamics. Use of molecular markers offers additional certainty for identifying specimens damaged during deep-sea collections and can elucidate often cryptic, intra- and interspecific diversity. The research presented in this study assessed broad genetic patterns of biodiversity in deep-sea cephalopods from …

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 …

Defining Data Science And Data Scientist, Dana M. Dedge Parks

USF Tampa Graduate Theses and Dissertations

The world’s data sets are growing exponentially every day due to the large number of devices generating data residue across the multitude of global data centers. What to do with the massive data stores, how to manage them and defining who are performing these tasks has not been adequately defined and agreed upon by academics and practitioners. Data science is a cross disciplinary, amalgam of skills, techniques and tools which allow business organizations to identify trends and build assumptions which lead to key decisions. It is in an evolutionary state as new technologies with capabilities are still being developed and …

Identifying New Treatment Options And Risk Factors For Type 2 Diabetes: The Potential Role Of Thymoquinone And Persistent Organic Pollutants, Shpetim Karandrea

USF Tampa Graduate Theses and Dissertations

Type 2 Diabetes Mellitus (T2DM) is a metabolic disorder characterized by chronic hyperglycemia, which develops as a consequence of peripheral insulin resistance and defective insulin secretion from pancreatic β-cells. A high calorie diet coupled with physical inactivity are known risk factors for the development of T2DM; however, these alone fail to account for the rapid rise of the disease. Recent attention has turned to the role of environmental pollutants in the development of metabolic diseases. PBDEs (polybrominated diphenyl ethers) are environmental pollutants that have been linked to the development of type 2 diabetes (T2D), however, the precise mechanisms are not …

An Evaluation Of The Water Lifting Limit Of A Manually Operated Suction Pump: Model Estimation And Laboratory Assessment, Katherine C. Marshall

USF Tampa Graduate Theses and Dissertations

With 663 million people still without access to an improved drinking water source, there is no room for complacency in the pursuit of Sustainable Development Goal (SDG) Target 6.1: “universal and equitable access to safe and affordable drinking water for all” by 2030 (WHO, 2017). All of the current efforts related to water supply service delivery will require continued enthusiasm in diligent implementation and thoughtful evaluation. This cannot be over-emphasized in relation to rural inhabitants of low-income countries (LICs), as they represent the largest percentage of those still reliant on unimproved drinking water sources. In that lies the motivation and …

Effects Of Release Contingencies On Bout-Like Responding, Chelsea E. Schubiger

USF Tampa Graduate Theses and Dissertations

Problem behavior is a concern for individuals with developmental disabilities. Research suggests that a release contingency time-out is effective to reduce problem behavior, but may increase the duration of time-out. Other sources recommend including a release contingency to avoid reinforcing problem behavior. It is possible clinicians generalize this concept to other domains, such as differential reinforcement with discrete-trial-training. Such a modification may be conceptualized as a tandem ratio requirement. Evidence from basic literature suggests that a tandem ratio requirement may increase a bout of responding. The current study examined effects of applied behavior analytic procedures using a bout analysis. The …

The Great Recession Of 2007 And The Housing Market Crash: Why Did So Many Builders Fail?, Mohamad Ali Hasbini

USF Tampa Graduate Theses and Dissertations

The “Great Recession” of 2007 created havoc in the homebuilding industry, more than any other previous economic down cycle. Countless seasoned local homebuilders across the country did not survive. The impact of their failure on the economy, community, employment, lenders, suppliers, and subcontractors was devastating. While previous studies have sought to identify the symptoms and causes of business failure, very little research has been done on home builder business failure due to acts, omissions, characteristics, or other events which are non-financial. Specifically, those that are attributable to the failed entities' top management and leadership during the housing crisis and the …

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 …

Measuring Up: Standardized Testing And The Making Of Postwar American Identities, 1940-2001, Keegan J. Shepherd

USF Tampa Graduate Theses and Dissertations

Standardized testing is a defining feature of contemporary American society. It not only governs how people are channeled through their schooling; it amplifies existing social disparities. Nonetheless, standardized testing endures, namely because it has served as a vital tool for the post-1945 American state. The postwar state prioritized, on the one hand, the cultivation of intellects resilient enough to sustain American geopolitical supremacy through scientific discovery and technological innovation and, on the other hand, the maintenance of an obedient population that would not disrupt existing social hierarchies. Standardized testing helped the postwar state solve this mind-body dilemma. As a function …

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 …

Cell Division Regulation In Staphylococcus Aureus, Catherine M. Spanoudis

USF Tampa Graduate Theses and Dissertations

Cell division is a fundamental biological process that occurs in all kingdoms of life. Our understanding of cell division in bacteria stems from studies in the rod-shaped model organisms: Gram-negative Escherichia coli and Gram-positive Bacillus subtilis. The molecular underpinnings of cell division regulation in non-rod-shaped bacteria remain to be studied in detail. Rod-shaped bacteria possess many positive and negative regulatory proteins that are essential to the proper placement of the division septa and ultimately the production of two identical daughter cells, many of which are absent in cocci. Given that essential cell division proteins are attractive antibacterial drug targets, it …

Graduate Nursing Student Persistence To Graduation, Tyler C. Dean

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate whether certain student-entry characteristics collected from an admissions application from one nursing school’s graduate (master’s degree) programs had a statistically significant relationship with student persistence. Specifically, the study determined if the variables sex, age at matriculation, U.S. citizenship, state residency status, most recent schooling year, last statistics course taken and grade, graduate-level program of study, and credit hours identified on the graduate nursing admissions application and school transcripts, had a statistically significant relationship in predicting student persistence to graduation. If a relationship existed, it would contribute to graduate student persistence literature and …

Validation Of Chimeric Viruses In Plaque Reduction Neutralization Test In Arboviral Disease Diagnostics, Jasmine Boykin

USF Tampa Graduate Theses and Dissertations

The plaque reduction neutralization test (PRNT) is a confirmatory diagnostic assay that is used to confirm a variety of diseases. The performance of PRNT requires the use of infectious wild type viruses, which increases the risk of laboratory acquired infections. For instance, eastern equine encephalitis (EEEV) is a highly virulent pathogen used in PRNT that can result in potentially fatal neurological diseases among humans and equines. Therefore, arboviral PRNT must be performed in Biosafety Level 3 (BSL-3) containment facilities and may require select agent approved scientists, like in the case of EEEV. These stringent requirements restrict the ability of public …

A Psychometric Evaluation Of The Compensatory Eating And Behaviors In Response To Alcohol Consumption Scale (Cebracs), Emily M. Choquette

USF Tampa Graduate Theses and Dissertations

Drunkorexia refers to a set of disordered eating behaviors that occur in the context of a drinking episode for the purpose of 1) off setting caloric intake of the alcohol or 2) increasing the effects of alcohol. The Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS) was developed with the purpose of measuring drunkorexia behaviors at three time points: before, during, and after a drinking episode. The purpose of this study was to further validate the measure for use in men and women by examining measurement invariance, reliability, and validity. First, single group confirmatory factor analyses (CFA) …

Vital Signs Of U.S. Osteopathic Medical Residency Programs Pivoting To Single Accreditation Standards, Timothy S. Novak

USF Tampa Graduate Theses and Dissertations

Osteopathic physician (D.O.) residency programs that do not achieve accreditation under the new Single Accreditation System (SAS) standards by June 30, 2020 will lose access to their share of more than $9,000,000,000 of public tax dollars. This U.S. Centers for Medicare & Medicaid Services (CMS) funding helps sponsoring institutions cover direct and indirect resident physician training expenses. A significant financial burden would then be shifted to marginal costs of the residency program’s sponsoring institution in the absence of CMS funding. The sponsoring institution’s ability or willingness to bare these costs occurs during a time when hospital operating margins are at …

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 …

Healthcare It In Skilled Nursing And Post-Acute Care Facilities: Reducing Hospital Admissions And Re-Admissions, Improving Reimbursement And Improving Clinical Operations, Scott L. Hopes

USF Tampa Graduate Theses and Dissertations

Health information technology (HIT), which includes electronic health record (EHR) systems and clinical data analytics, has become a major component of all health care delivery and care management. The adoption of HIT by physicians, hospitals, post-acute care organizations, pharmacies and other health care providers has been accepted as a necessary (and recently, a government required) step toward improved quality, care coordination and reduced costs: “Better coordination of care provides a path to improving communication, improving quality of care, and reducing unnecessary emergency room use and hospital readmissions. LTPAC providers play a critical role in achieving these goals” (HealthIT.gov, 2013).

Though …

The Impact Of Implementation Fidelity On Middle School Student Outcomes In The Life Skills Training Program, Enya B. Vroom

USF Tampa Graduate Theses and Dissertations

Social and emotional learning (SEL) programs have become increasingly popular during last 20 years, and have shown to reduce risky behaviors (i.e., substance use), improve communication skills, academic performance, and relationships among students of all ages when implemented in schools (Weissberg, Durlak, Domitrovich, & Gullotta, 2015; Durlak, Weissberg, Dymnicki, Taylor, & Schellinger, 2011). Although the benefits of SEL programs are significant, the issue of implementation fidelity often arises. The purpose of this study was to assess the impact of implementation fidelity in the Life Skills Training program (LST) implemented with middle school students of a large South Florida school district. …

Synthesis, In Vitro Characterization And Applications Of Novel 8-Aminoquinoline Fluorescent Probes, Adonis Mcqueen

USF Tampa Graduate Theses and Dissertations

Malaria is a parasitic disease that is caused by the plasmodium parasite. Plasmodium infection has affected man for thousands of years. With advances in drug discovery over the past century, malaria has evolved to possess resistance to most mainline therapeutics. This war of drug discovery vs plasmodium evolution continues to be fought to this very day, with attempts to eradicate malaria worldwide. Frontline treatments such as chloroquine, artemisinin, and atovaquone/proguanil have all seen parasitic resistance in strains of P. vivax as well as P. falciparum. While plasmodium possesses resistance to most classes of anti-malarials, the 8-aminoquinoline (8-AQ) class has …

Microfluidic Biopsy Trapping Device For The Real-Time Monitoring Of The Tumor Microenvironment, Angela Holton

USF Tampa Graduate Theses and Dissertations

The tumor microenvironment is composed of cellular and stromal components such as tumor cells, mesenchymal cells, immune cells, cancer associated fibroblasts and the supporting extracellular matrix. The tumor microenvironment provides crucial support for growth and progression of tumor cells and affects tumor response to therapeutic interventions. To better understand tumor biology and to develop effective cancer therapeutic agents it is important to develop preclinical platforms that can faithfully recapitulate the tumor microenvironment and the complex interaction between the tumor and its surrounding stromal elements. Drug studies performed in vitro with conventional two-dimensional cancer cell line models do not optimally represent …

The Relationship Between Chronic Health Conditions And Health Literacy, Resiliency And Support/Self-Advocacy In Youth, Mercedes N. Cambric

USF Tampa Graduate Theses and Dissertations

Over the past several decades the number of youth living with a chronic health condition has drastically increased. A chronic health condition can be defined as an illness that lasts three months or more that can be controlled but not cured (Centers for Disease Control and Prevention [CDC], 2010). Although there is existing literature on youth with chronic health conditions, there are very few studies that examine the levels of health literacy, resiliency and support/advocacy within this population. The current study is a secondary analysis that utilized data collected from the 37-item Youth Health Literacy and Resiliency Scale (HLRS-Y version) …
