USF Tampa Graduate Theses and Dissertations

Parametric analysis of any real-world data is the most powerful tool to characterize the probabilistic behavior in social, economic, medical, epidemiological, and other areas of study. In the present study, we identify the theoretical Probability Distribution Function(PDF) for Democracy Index Scores (DIS) from the Economist Intelligence Unit (EIU) database and estimate the maximum likelihood estimates of the theoretical PDFS. We also identify the individual PDFs for each of the clusters, Full Democracy, Flawed Democracy, Hybrid Regime, and Authoritarian Regime defined by the Economist Intelligence Unit (EIU).

A statistical model is a convenient instrument to predict the future value of any …

From C++ To Conscientiousness: Modeling The Psychosocial Characteristics Influencing Cybersecurity Personnel Performance, Rachel C. Dreibelbis

USF Tampa Graduate Theses and Dissertations

The current study drew upon several theoretical frameworks of cybersecurity performance to evaluate distal and proximal individual attributes that may predict cyber performance in a variety of cybersecurity work roles. The proposed models in this study predicted that cognitive ability, personality (conscientiousness and openness to experience), and motivational factors like learning orientation would work through proximal attributes like technical knowledge, communication, and problem solving to influence performance. Hypotheses were tested using 139 employee responses to predictor variables and performance ratings from their supervisors across two industries and several cybersecurity work roles. Correlational analyses and path models supported that several individual …

Using Flipped Classrooms To Teach Mathematics To Elementary Students In Saudi Arabia, Fawaz Alrouqi

USF Tampa Graduate Theses and Dissertations

During the years 2003, 2007, 2011, and 2015, Trends in International Mathematics and Science Study (TIMSS) revealed that students in Saudi Arabia had a below-average mathematics performance among 4th and 8th-grade students. The modern and innovative techniques and strategies of teaching, such as the flipped classroom method, should replace traditional teaching methods to improve the performance and growth of students. This qualitative multiple case study explores a deeper understanding of the perspectives and the experiences of three elementary mathematics teachers when using a flipped classroom model in Saudi Arabia.

Design And Implementation Of Degenerate Qpcr/Qrt-Pcr Primers To Detect Microbial Nitrogen Metabolism In Wastewater And Wastewater-Related Samples, Ryan F. Keeley

USF Tampa Graduate Theses and Dissertations

Nitrogen cycling processes can be tracked using quantitative Polymerase Chain Reaction (qPCR) to determine the presence and qReverse Transcriptase-PCR (qRT-PCR) to determine expression of key genes, or ‘biological markers’, for nitrogen metabolism. Nitrification is catalyzed in part, by two enzymes: ammonia monooxygenase (AMO; NH3 NH2OH) and nitrite oxidoreductase (NXR; NO2- NO3-). For denitrification, four enzymes act sequentially: nitrate reductase (NAR/NAP; NO3- NO2-), nitrite reductase (NIR; NO2- NO), nitric oxide reductase (NOR; NO  N2O), and nitrous oxide reductase (NOS; N2O  N2). A principle of wastewater treatment (WWT) is to remove excess nitrogen by taking advantage of natural nitrogen cycling …

Human Rights, Emotion, And Critical Realism: Proposing An Emotional Ontology Of International Human Rights, Ben Luongo

USF Tampa Graduate Theses and Dissertations

This dissertation proposes a critical realist framework of human rights and argues that emotion plays a foundational role in constituting a human rights ontology. I build this framework as a critical response to other IR human rights theories which have largely been developed in accordance with either empiricist or rationalist paradigms. Both empiricist and rationalist theories fail to articulate a firm ontological foundation which can support their human rights claims.

This ontological concern may not seem too important for human rights scholars interested in more substantive political issues, but it does lead to problems because no human rights theory is …

On Her Own: A Qualitative Study On The College-To-Career Transition Of Black Second-Generation Alumnae, Ladessa Y. Mitchell

USF Tampa Graduate Theses and Dissertations

The purpose of this qualitative study was to describe the college-to-career transition of Black second-generation alumnae in the development phase of emerging adulthood using Schlossberg’s (2011) Transition Model. As the researcher, I collected data from Black second-generation alumnae of predominantly White public universities in Florida to examine how their intersecting identities (i.e., race, gender, and educational status) and use of metaphorical capital (i.e., social, cultural, and human capital) influence their transition. The conceptual framework for this study is based on the 4 S’s of Schlossberg’s Transition Model as well as emerging adulthood, forms of capital, and the intersecting identities of …

Mtss Implementation In High Schools: Expert And Stakeholder Perspectives, Julie Daye

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the perspectives of experts and school-level stakeholders on MTSS implementation in high schools. Despite evidence of MTSS implementation effectiveness in elementary and middle school settings, MTSS implementation still lags in high schools. In reviewing the literature on high school MTSS implementation, those who have worked to implement MTSS do not all do so with the same priorities and/or emphases. I collected and examined qualitative data that reflects the perspectives of experts and school-level stakeholders. Specifically, I also reviewed articles or book chapters written by some high school MTSS experts and interviewed them. I interviewed stakeholders working in …

Making A Case For Equity Planning In Transportation Development: Identifying Indicators And Building A Framework For Hillsborough County, Fl, Dayna J. Lazarus

USF Tampa Graduate Theses and Dissertations

The idea that planners should work toward an equitable society has been part of the profession since the 1960s, largely based on the work of planning theorists like Paul Davidoff, Sherry Arnstein and Norman Krumholz. Transportation planning, however, has been slower than other sectors of the profession, such as housing, to embrace equity planning concepts. That has begun to change as concerns about income inequality, environmental justice and climate change have become more salient. This thesis makes the case that in order to improve social equity outcomes, transportation planners must make social equity an explicit goal and add social equity …

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, …

Assessing The Effectiveness Of Antecedent And Consequent Interventions To Enhance Sports Performance, Merritt Schenk

USF Tampa Graduate Theses and Dissertations

Sports research in behavior analysis is becoming increasingly popular. As the proliferation of research continues, multiple interventions have been shown to help enhance sports-related performance. However, different intervention components are rarely if ever used alone, which has created a limitation with the current body of research. To begin to address this limitation, this study had three experiments to evaluate some different components of video recording procedures and behavioral skills training (BST) to facilitate performance enhancement. Experiment 1 separated video modeling and video feedback to see which component best improved pitching form in Little League baseball players. Experiment 2 evaluated video …

With increasing popularity, online games provide a rich recording of social dynamics that can contribute to understanding human behavior. This dissertation studies two phenomena of social dynamics at large scale using data traces from online games. The first phenomenon is team formation and the second is players mobility between gaming servers.

This dissertation first presents a framework for collecting data from online gaming through crawling. It includes the data sources and the tools used for data …

For The Common Defense: The Evolution Of National Security Strategy-Making Institutions & Impact On American Grand Strategy, Nathan D. Barrick

USF Tampa Graduate Theses and Dissertations

This dissertation applies a Neoclassical Realism model to examine how the evolution of United States (U.S.) national security strategy-making institutions has resulted in a path dependent accrual of autonomy and increasing influence over the formulation of American grand strategy. Once U.S. national security strategy-making institutions were created, their existence inexorably led to increasing autonomy, the creation of new strategy-making institutions, and subtle influence in shaping American grand strategy by preferential focus on a militarized foreign policy. Additionally, the more autonomous these strategy-making institutions have become, the further they have strayed from the Constitutional mandate to create a government which provides …

Bystander Intervention, Victimization, And Routine Activities Theory: An Examination Of Feminist Routine Activities Theory In Cyber Space, Jennifer A. Leili

USF Tampa Graduate Theses and Dissertations

Routine Activities Theory (RAT) is one of the most widely used theories to explain victimization. It has been applied to a wide range of criminal victimizations, such as property crimes (Miethe, Stafford, & Long, 1987) and urban murder (Messner & Tardiff, 1985). While traditional RAT has been used to explain violence against women, the feminist perspective of RAT developed by Schwartz and Pitts (1995) provides a better explanation by incorporating cultural factors that shape the conditions that give rise to offending. The current study draws on feminist RAT in order to explore three different types of victimization involving women: stalking, …

An Insight Into The Biological Functions, The Molecular Mechanism And The Nature Of Interactions Of A Set Of Biologically Important Proteins., Adam A. Aboalroub

USF Tampa Graduate Theses and Dissertations

Characterization of protein structural properties is crucial to determine its role in normal and pathological conditions. In this dissertation, we have employed NMR spectroscopy in a combination of other biochemical and biophysical techniques to investigate the catalytic function, the molecular mechanism, and nature of the interactions of bmAANAT3, Cdc37, and TIMP2, respectively.

In the first project, we have employed an arylalkylamine N-acetyltransferases (AANATs) from Bombyx mori (bmAANAT3) to determine the role of the acetyl-group in coordinating the catalytic cycle in this family of enzymes. We have found that the occupancy of the acetyl-moiety in the catalytic funnel of these enzymes …

Novel Strategies On Characterizing Biologically Specific Protein-Protein Interaction Networks, Bi Zhao

USF Tampa Graduate Theses and Dissertations

The function, behavior, and environmental response of biological systems are essentially determined by the complex interaction and regulation of biomolecules inside the systems. Therefore, it is critical to characterize the inter-molecular interaction and regulation of biomolecules inside these systems. In this direction, many experimental techniques have been developed and these techniques have been used in many different model systems under various conditions. Consequently, a massive amount of data has been generated. These data cover multiple aspects of molecular interaction and regulation, such as protein-protein interaction, microRNA-RNA interaction, gene expression profiles, etc. While carrying rich information, these data may also contain …

Understanding The Mechanisms Between Job Stress And Employee Sleep: A Daily Diary Study, Marijana L. Arvan

USF Tampa Graduate Theses and Dissertations

The present study investigated how three job stressors, workload, unfinished tasks, and mistreatment from coworkers and supervisors, manifest in sleep impairment. Using the transactional model of stress, allostatic load model, the cognitive activation theory of stress (CATS), and findings from the sleep medicine literature, each job stressor was predicted to have three distinct pathways to sleep quality: an affective path (anger or anxiety), a cognitive path (anticipatory stress or rumination), and a behavioral path (sleep hygiene behaviors). The proposed models argued for two-stage mediation, in which the cognitive and affective strains of job stressors impact sleep quality both directly and …

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 …

Design And Synthesis Of Novel Agents For The Treatment Of Tropical Diseases, Linda Corrinne Barbeto

USF Tampa Graduate Theses and Dissertations

Infectious diseases have had an impact on populations since the beginning of humanity. Despite huge advances in the fight against these conditions, they continue to be the leading cause of death and disability for a large portion of the world’s populace. Those most adversely affected predominately live in the more improvised areas of the developing world. Often treatments are made inaccessible to these areas due to cost, complicated administration requirements, severe side effects, and / or compound instability. Even when treatments are available the accelerated development of resistance has created an urgent need for the creation of new molecules with …

Inside The Work Of A Rookie Principal Coach: Tackling Equity In Disciplinary Practices, Olayinka A. Alege

USF Tampa Graduate Theses and Dissertations

Hillsborough County Public Schools embarked on an ambitious goal to improve the highest-need schools by restructuring how the district supports schools and their leaders in July 2018. As part of this effort, the superintendent reduced the span of control and assigned principal coaches to support principals in a more intentional way. The purpose of this study was to explore how a principal coach engages a principal in examining inequities in disciplinary practices and how the principal coach provides the supports to prompt and sustain the principal’s efforts to reduce the disproportionate number of students of color being suspended from school. …

Widow Narratives On Film And In Memoirs: Exploring Formula Stories Of Grief And Loss Of Older Women After The Death Of A Spouse, Jennifer R. Bender

USF Tampa Graduate Theses and Dissertations

This dissertation analyzes narratives (written and mediated) about widows’ post-loss experiences—specifically the ways in which these women embody and adjust/adhere to their post-loss widow identities—and whether or not the canonical/formula stories about widows reflect current experiences of widowhood. I look at older widowed women—both those in well-read widow memoirs and also in media portrayals of widows on film. The canonical view of widows as not attractive, not useful, and not interesting needs to be reexamined in light of changing ideas about gender roles and increased longevity. Surely older women have experiences, desires, and goals that encompass more than being socially …

Prejudice Asymmetry: The Cultural Acceptance Of Sexism, Sophie Kuchynka

USF Tampa Graduate Theses and Dissertations

Sexism tends to be a culturally accepted form of prejudice. I propose the relatively strong trivialization of societal sexism stems from the unique benefits that men receive from the gender status hierarchy, compared to other types of group-based hierarchies. Three studies examined why people, men in particular, trivialize or justify gender bias in relation to other types of group-based biases. Study 1 was a correlational study that examined whether participants downplay the existence and social harm of gender bias in relation to racial, religious, and sexual orientation bias, moderated by participant gender. Participants reported stronger trivialization and denial of gender …

The Left Behind Generation: Instructional Practices To Increase The Technological Literacy Of Older Adults, Daphne Pace Phillips

USF Tampa Graduate Theses and Dissertations

This study sought to explore the utilization and perception of best practices by community-based technology training programs when instructing older adults to become technologically literate. The target population included adults age 55 years and older of the Baby Boomer generational cohort who ranged academically from possessing a high school diploma or General Education Diploma (GED) through a college degree and had enrolled in a local technology training program to improve their technological skill level with the goal of obtaining employment and/or to remain functionally independent. This study was conducted at three community technology training centers located in the southeast that …

The Teacher Evaluation Conundrum: Examining The Perceptions Of Special Education Teachers, Gordon Brobbey

USF Tampa Graduate Theses and Dissertations

For more than a decade now, state and local education agencies have adopted high-stakes teacher evaluation systems in response to federal accountability mandates and the recognition of the critical role of teacher effectiveness in student achievement. Teacher evaluation systems have revealed relevant details regarding teacher effectiveness, especially in general education settings. However, no systems of teacher evaluation have been developed and evaluated for special education teachers and little is known about how special education teachers have fared under the accountability microscope. The study was informed by three significant issues pertaining to special education teacher evaluation: (1) the challenges surrounding evaluation …

Targeting Pten For Therapy In Cancer And Ptenopathies, Emily Palumbo

USF Tampa Graduate Theses and Dissertations

PTEN, a dual protein and lipid phosphatase, regulates a myriad of cellular functions including PI3K pathway signaling, cell migration, proliferation, invasion and apoptosis. PTEN mutations often lead to multiple malignancies, including prostate, breast, endometrial, skin and brain cancers, associated with hyperactive PI3K signaling. PTEN mutations have also been associated with a variety of other diseases, classified as PTEN Hamartoma Tumor Syndromes (PHTS). In addition, compromised function or reduced expression of PTEN due to non-genomic mechanisms are associated with many types of hyperproliferative diseases, such as restenosis and neoplastic diseases, including melanoma, lung, breast, prostate and colon cancers. Although PI3K pathway …

Queer Authority In Old And Middle English Literature, Elan J. Pavlinich

USF Tampa Graduate Theses and Dissertations

I argue that select early English texts queer normative authorizing conventions to authorize Old English and Middle English literatures. During the European Middle Ages, Latin cultures and literatures were privileged with authority that extended to and subverted the cultural capital of the inhabitants of England at the edge of the known Western world. I identify four exceptional English texts that employ authorizing conventions to disrupt normative networks of power that traditionally privilege Latin and to authorize English literature instead. The Norman Conquest had altered the English language and social structures; still, these altered networks of power continued to marginalize English …

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 …
