Specification, Enforcement, And Measurement Of Integrity Policies, Kevin Dennis

USF Tampa Graduate Theses and Dissertations

The first step to improving an organization's security posture is to define the organization's security goals. At a technical level, these goals are expressed as security policies. Security policies are predicates over programs, that return true or false if the program adheres to the policy. Defining these policies correctly is thus essential to ensuring the overarching security goals are met, but it is often quite difficult to translate human-oriented goals into their technical policy counterparts. In addition, these policies must be specified so that they are enforceable while minimizing false positives and false negatives. Integrity policies, which specify how data …

The Relationship Between Rejection Sensitivity And Higher Order Cognitive Functions, Rachel Gaynor

USF Tampa Graduate Theses and Dissertations

Rejection sensitivity indexes individual differences in the expectation of, reaction to, and interpretation of possible rejection. Research on mechanisms underlying these individual differences have identified a reduction in top-down emotion regulatory processes in those exhibiting heightened rejection sensitivity. Most of these studies utilize rejection-specific affective stimuli. This study examined the relationship between rejection sensitivity score, calculated from the 18-question RSQ, and the recruitment of higher level inhibition resources, as indexed by the conflict N2, on three novel Flanker tasks. In order to further examine previously identified patterns in affective inhibition across differing levels of rejection sensitivity, and to determine whether …

An Evaluation Of Reinforcement Thinning Using Deposit Contracts To Increase Physical Activity, Madeline N. Mccullen

USF Tampa Graduate Theses and Dissertations

Due to the health risks associated with a sedentary lifestyle, researchers have used behavioral interventions such as contingency management and deposit contracts to increase physical activity. Although these interventions have been effective, researchers have described the lack of maintenance assessments of the target behavior. One way to address the maintenance of behavior, such as physical activity, is with reinforcement thinning. The current study evaluated the effects of self-tailored deposit contracts and reinforcement thinning on daily step count with sedentary adults using a nonconcurrent multiple baseline across participants design. Researchers and participants designed a self-tailored deposit contract by identifying a step …

Exploring The Enlightenment Function Of Thought Experiments: Unveiling An Underdeveloped Dimension Absent In Typologies, Dominique Greene-Sanders

USF Tampa Graduate Theses and Dissertations

Thought experiments (TEs) are imaginative tools used across various fields to explore theoretical and practical issues. This dissertation focuses on the application of TEs in ethics, specifically emphasizing the underdeveloped enlightenment function. The traditional use of TEs in ethics often aims to clarify, support, or refute specific claims through an argumentative structure. However, this work argues that TEs also play a key role in enhancing ethical competence by acknowledging the complexities of ethical dilemmas and fostering moral skills like critical thinking, moral reasoning, and ethical awareness through non-argumentative and non-theory-centric means.

The dissertation begins by explaining the nature and historical …

The Effects Of Scenic Pictures And Progressive Time Delay On Intraverbal Responding, Breanna White

USF Tampa Graduate Theses and Dissertations

Researchers have demonstrated the effectiveness of tact prompts to establish single responses to questions about intraverbal categories. Scenic pictures, a visual depiction of multiple exemplars belonging to a stimulus class, may increase the likelihood that individuals will emit multiple responses when answering categorical questions, and promote response variability. The purpose of this study was to extend Glodowski and Rodriguez (2019) by evaluating the effectiveness of a larger array of visual stimuli and progressive time delay on varied intraverbal responding with individuals diagnosed with autism spectrum disorder between the ages of 8 and 17 within a private school for individuals with …

Personality Pathology As A Self-Regulating Dynamical System, Haya Fatimah

USF Tampa Graduate Theses and Dissertations

With mounting evidence that personality is both stable and variable, personality scientists have called for comprehensive approaches that integrate stability and dynamics. Dynamical systems theory offers concepts and tools to systematically integrate the stable and dynamic components of personality while identifying the relationship between these components. This study extends the dynamical systems approach to personality pathology and investigates how pathological personality states vary in a patterned manner in relation to their equilibria or attractors, as opposed to random noise. Furthermore, I test if these patterned dynamics may describe important individual differences and predict behavioral outcomes. Using daily data pertaining to …

Sars-Cov-2 Neurotropism: Understanding Effects At The Blood-Brain Barrier And Hematogenous Neuroinvasiveness, Taylor E. Martinez

USF Tampa Graduate Theses and Dissertations

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19, has provisional counts of over 110 million documented cases and 1.218 million deaths (as of February 2024) in the United States since January 2020. SARS-CoV-2 is an airborne respiratory virus that primarily infects the lungs via the ACE2 receptor but has well-documented secondary target organs including the kidneys, the gastrointestinal tract, the heart, and the skin. SARS-CoV-2 also infects the brain, but the hematogenous route of viral entry to brain is still not fully characterized. Understanding how SARS-CoV-2 traverses the blood-brain barrier (BBB) as well as how it …

Subtropical Estuarine Ecosystems Display Both Long-Term Stability And Change, Garrett L. Miller

USF Tampa Graduate Theses and Dissertations

Subtropical estuaries often support abundant and diverse faunal assemblages, but it is unclear how these productive ecosystems are responding to climate change. In the eastern Gulf of Mexico, estuarine faunal assemblages have been sampled for decades as part of a fisheries-independent long-term monitoring program. I assessed trends in submerged aquatic vegetation, water temperature, and the abundance, richness, and structure of faunal assemblages over more than two decades in four estuarine systems using this dataset. I used both univariate and multivariate analyses to quantify and describe the dynamics of these habitat and faunal variables. Further, I separated my analyses for summer …

Internalized Binegativity, Alcohol Consumption, And Expectancies Following An Experience Of Binegativity: An Experimental Study, Alexander P. Rivera

USF Tampa Graduate Theses and Dissertations

Individuals who identify as bisexual have repeatedly been found to consume alcohol at higherrates than individuals who identify as heterosexual or homosexual and are at greater risk for developing AUD. Per the Minority Stress Model, this heightened risk for bisexuals’ poor alcohol outcomes may be attributed to experiences of bisexual-specific stressors (i.e., experienced binegativity) and beliefs about their own bisexual identity., which have previously been associated with increased alcohol use. To date, however, no studies have examined if experiences of binegativity are associated with changes in internalized binegativity and alcohol outcomes in an experimental design. The current study aimed to …

Classifying Traumatic Brain Injury: Associations With Executive Functioning And Externalizing Behavior, Lauren F. Fournier

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) involves a head injury that is, for some individuals, associated with long-term behavioral difficulties, including externalizing behaviors. The literature on TBI and its links to externalizing is limited in several important ways. First, there is evidence that current classification system of mild, moderate, or severe is imprecise and contains important variation within TBI categories. Second, TBI and externalizing are understudied among high functioning individuals, such as undergraduate students, despite rates of TBI among this population that are similar to those of the general population. Third, while it is theorized that executive functioning deficits explain the association …

Predicting Ph At In-Situ Temperature For Aquatic Environments, Sarah E. Bartoloni

USF Tampa Graduate Theses and Dissertations

pH is typically measured at a constant temperature and, as needed, converted to in-situ temperature using a system of thermodynamic equations. Using this equilibrium approach, adjustment of pH to in situ conditions requires two measured CO2 system parameters (pH, total alkalinity, dissolved inorganic carbon, or CO2 fugacity). Currently, when pH is the only measured CO2 system parameter, linear models are used to adjust the pH to in-situ temperature. Although many studies have attempted to optimize CO2 equilibrium constants (K1 and K2) for the CO2 system over a range of conditions, very little prior work has experimentally examined which CO2 system …

Us Elementary Teachers’ Perspectives With The Use Of Rubrics In Elementary Classrooms: A Shift From Traditional Assessment To Alternative Assessment, Roaa Adel Alajaji

USF Tampa Graduate Theses and Dissertations

This study was conducted to explore US elementary teachers’ perceptions of their experiences using rubrics as a tool for student self-assessment and metacognition (assessment for learning) to improve elementary students’ achievement and their instructional decision-making at a private American elementary school in South Florida. The constructivist learning theory by Piaget (1970) and Vygotsky (1978), which emphasized that knowledge is best gained through the interaction of experiences and ideas in one’s mind and the interaction with others, framed the study. Three semi-structured interviews were conducted with eight elementary teachers: three third-grade teachers, three fourth-grade teachers, and two fifth-grade teachers. Using thematic …

Essays On The Determinants Of Women's And Children's Health In Bangladesh, Md Shahjahan

USF Tampa Graduate Theses and Dissertations

My dissertation is titled "The Determinants of Women's and Children's Health in Bangladesh." The first chapter studies the impact of a Bangladeshi schooling program on child immunization rates. The program provided a stipend and other incentives to attend secondary school, significantly increasing rural girls' education. I hypothesize that this would lead to higher immunization rates in the next generation since better-educated mothers have better knowledge of health practices. The study uses a regression model ("difference-in-differences"), which is based on differential exposure to the 1994 Female Secondary School Stipend Program (FSSSP) by birth cohort and rural residence. I find that the …

Did I Do That?: Lived Experience And Media Representation Of The Awkward Black Girl, Kendra Williams

USF Tampa Graduate Theses and Dissertations

For my thesis project I will introduce the Awkward Black Girl as a new race gender script. Though there are minor nuances of the Awkward Black Girl within television, Issa Rae’s performance of the Awkward Black Girl in Misadventures of Awkward Black Girl and the HBO hit series Insecure remains prevalent to contemporary media representations. Though there is limited scholarship within the field of Communication available about the Awkward Black Girl, most of the scholarship consists of analysis and discourse centering Rae’s portrayal in her web series and television show. I explore Quinta Brunson’s portrayal of the Awkward Black Girl …

Quality Of Life Factors In Children With Dual Diagnosis Stuttering And Autism Spectrum Disorder, Kristen N. Rollins

USF Tampa Graduate Theses and Dissertations

Addressing quality of life is a critical part of speech-language pathology. Understanding quality of life deficits and challenges in our patients’ lives allows us to provide well-rounded treatment. Quality of life in children who stutter and children with autism spectrum disorder has been heavily researched (children with autism spectrum disorder to a lesser extent). However, despite approximately 1 in 1000 children being dually diagnosed with stuttering and autism spectrum disorder (Briley & Ellis, 2018), quality of life in this population has never been researched. This thesis aims to determine whether children diagnosed with both conditions experience similar quality of life …

Effects Of Intercultural Interactions In 3d Virtual World On Efl Students’ Intercultural Communicative Competence, Foreign Language Anxiety, And Motivation, Umi H. Saidah

USF Tampa Graduate Theses and Dissertations

Virtual worlds (VWs) as emerging technologies have been perceived as positive by students for foreign language (FL) learning. VW affordances of presence and immersion have enabled FL researchers and practitioners to design and develop classroom-like environments in virtual settings, allowing authentic intercultural interactions from different geographical locations, in a variety of languages. This study conducted mixed methods research to deliver English lessons via an immersive 3D VW for avatar-context-avatar interactions via voice chat with a view to improving ICC necessary for effective intercultural interaction. The avatar-avatar interactions were between a native English-speaking instructor and English as a foreign language (EFL) …

USF Tampa Graduate Theses and Dissertations

At all levels of healthcare, providers are experiencing rising levels of professional burnout. For healthcare provider leaders, burnout is particularly critical since leaders must maintain healthy and trusting relationships with patients and their teams of healthcare professionals. This utilization-focused evaluation study explores an arts intervention program designed to promote cultural humility among healthcare providers. Increased cultural humility may provide coping tools for healthcare providers to ward off burnout. The arts intervention took place over three sessions: one at a museum, one virtual, and one at a hospital. Four types of data were collected including a quantitative pre- and post-survey, observation …

A Phase-1 Trial Of Intensive Hybrid Stuttering Modification/Fluency Shaping Therapy, Jessica Smith

USF Tampa Graduate Theses and Dissertations

Purpose: The purpose of this study was to analyze changes in frequency stuttering behaviors, speech rate, and feelings/attitudes following the University of South Florida Program for Advanced Treatment of Stuttering (USF-PATS), a hybrid stuttering modification/fluency shaping program intended for teenagers and adults who stutter moderately to very severely.

Method: Baseline and post-treatment speech samples for participants (N = 3) were analyzed for speech rate and presence of stuttering behaviors (repeated movements, fixed postures, and superfluous behaviors) across conditions (monologue and reading). An abbreviated thematic analysis was completed to analyze feelings/attitudes post-treatment.

Results: Results revealed a decrease to zero and near-zero …

Essays In The Econometrics Of Choice Analysis With Applications In Health Economics, Maksat Jumamyradov

USF Tampa Graduate Theses and Dissertations

Unobserved heterogeneity is one of the main concerns for applied economists, particularly when modeling preferences for health and healthcare. Applied economists have preferred the mixed logit model due to its flexible latent structure allowing various specifications of unobserved heterogeneity. Since the model does not have a closed-form, its estimation relies on simulation-based methods, specifically the maximum simulated likelihood (MSL) estimator, which has been the dominant estimation strategy. In the first section of this dissertation, which include chapters 1 through 5, I analyze biases of MSL when applied to the bivariate normal, bivariate Poisson-lognormal and mixed logit models.

Discrete choice experiments …

Causes And Consequences Of Word Skipping During Reading: Evidence From The Co-Registration Of Eye Movements And Eeg, Sara Milligan

USF Tampa Graduate Theses and Dissertations

Skilled readers skip approximately one third of the words in the text while reading for comprehension (Rayner, 1998). Therefore, a prominent question for decades among reading and language researchers has been how people are able to recognize words and comprehend text without even looking at all of the words. Eye tracking studies have established that some information about an upcoming word in the text can be identified while still looking at the previous word (Rayner, 1975), but it remains an open question whether words that are skipped are thoroughly identified or if skipping decisions are based on shallow heuristic factors, …

“A Second Chance Citizen Reintegration Program Through The Lenses Of Black And Brown Participants And Case Managers.”, Bobbie Straughter

USF Tampa Graduate Theses and Dissertations

Recidivism has been linked to a lack of education opportunities, heightened surveillance, a lack of housing stability, and limited access to resources for assistance. Because Black and Brown communities are facing mass incarceration, there is a growing concern about recidivism, as they are affected by several factors that may make them more likely to re-offend upon release. These include a lack of mental health outreach, their socioeconomic status, environmental influences, and the challenges they face regarding their masculinity and role in fatherhood. To both reduce recidivism and provide a solution to the obstacles presented above, the literature suggests providing re-entry …

Differences In Speech Patterns Produced By Spanish-English Language Learners During Single-Language And Mixed-Language Remote Academic Vocabulary Instruction, Ester Garcia

USF Tampa Graduate Theses and Dissertations

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of “fluency,” to characterize knowledge of a language. Prior research indicates that some speech disfluency patterns may be more common among Spanish-English bilingual children, who tend to produce more mazes (fragments of an utterance) and syllable repetitions than their monolingual peers. These patterns have been attributed to 1) acquiring a new language; 2) the influence of Spanish as a first language (L1) on …

High School Acceleration And First-Year College Student Success: Do Advanced Placement Or Dual Enrollment Influence College Persistence Differently, Serge W. Desir Jr.

USF Tampa Graduate Theses and Dissertations

The proliferation of Advanced Placement (AP) and Dual Enrollment taken by high school students expanded over the past few decades due concerted efforts to make the accelerated mechanisms more available to historically underrepresented groups and to reduce the cost of higher education. Supported by years of research correlating improved first-year college performance to enrollment in such programs, AP and Dual Enrollment also allow students to earn college credit prior to enrolling at post-secondary institutions, further enhanced their appeal. Despite this enhanced popularity, little research has been done on whether there are any indications of different academic outcomes by the accelerated …

Spectral Properties Of Wetlands In Michigan Using Remote Sensing To Identify And Classify Wetlands In Roscommon County, Michigan, Kolin Williamson

USF Tampa Graduate Theses and Dissertations

Biological, geological, and physical. These are only a handful of the many environmental aspects that wetlands functions maintain and protect. Unfortunately, wetlands within the United States have been razed at an alarming rate. The State of Michigan has not gone through this unscathed either, loosing over 1000 acres of wetland a year. One of the most important tools to prevent this destruction are the maps and programs that show where these essential ecosystems are located. The current, federally-created maps and imaging software in use by environmental consultants and contractors may not be up to date which can pose challenges for …

Slot Machine Addiction: The Untold Story Of Contradictions Between Self And America's Neoliberal Risk Society, Melanie C. Falconer

USF Tampa Graduate Theses and Dissertations

The ability to take risks is nothing short of heroism in the modern United States which thrives on a diet of hyper mobility, technological progress, and globalized, deregulated “free” markets. Such relentless instability affirms scholarly contentions that the U.S. is now a “risk society.” Indeed, in Gambling with the Myth of the American Dream: The Pokerization of America, rhetoric scholar Aaron Duncan suggests that media stories of modern poker tournaments signify a collective desire to grapple with this heightened modern “chanciness” within our established gambling lore and make it cohere with our deeply cherished notions of American individualism. While Duncan …

A Republic Of Pawprints: The Rise And Reign Of The Alaskan Sled Dog, 1870-1970, Christopher David Adkins

USF Tampa Graduate Theses and Dissertations

This dissertation charts the career of the Alaskan sled dog: how it was used as an engine of development, how it became a symbol for early American Alaska, and how it fell victim to obsolescence as newer and faster means of conveyance became available. The figure of the sled dog in the Arctic is complex. Because it was closer to the wolf in phenotype both it, and Alaska, were buffeted by the same White settler expectations and Darwinian chauvinism which afflicted its Indigenous peoples. This would intensify during the baptisms by fire of the gold rushes. Dog abuse – overwork, …

Multivalency Of The Mdmx Acidic Domain Slims Use Different Binding Modes To Inhibit Mdmx And P53, Malissa Fenton

USF Tampa Graduate Theses and Dissertations

Regulation of protein binding through autoinhibition commonly occurs via interactions involving intrinsically disordered regions (IDRs). These intramolecular interactions can directly or allosterically inhibit intermolecular protein or DNA binding, regulate enzymatic activity, and control the assembly of large macromolecular complexes. Autoinhibitory interactions mediated by protein disorder are inherently transient, making their identification and characterization challenging. In this work, we explore the structural and functional diversity of disorder-mediated autoinhibition for a variety of biological mechanisms, with a focus on the role of multivalency and effective concentration. We also discuss the evolution of disordered motifs that participate in autoinhibition using examples where sequence …

Context-Aware Affective Behavior Modeling And Analytics, Md Taufeeq Uddin

USF Tampa Graduate Theses and Dissertations

Affective computing (AC) is a sub-domain of AI that has the potential to assist people by assessing mental states and making appropriate recommendations to patients, loved ones, caregivers, and domain experts. Humans usually produce an enormous amount of data (such as face videos) every day. One of the major challenges for affective computer vision is to efficiently deal with high volumes of data to facilitate automated model development. To cope with this challenge, we developed computer vision algorithms that measure the expressivity of the human face from video data. More precisely, the developed algorithms can map complex affect information from …

Platonic Intelligence And The United States Constitution, Elizabeth M. Iglesias

USF Tampa Graduate Theses and Dissertations

This dissertation demonstrates the Platonic logic that informs the order of value and design elements of the U.S. Constitution as defended in the Federalist Papers. The dissertation has four movements that reveal the Platonic logic of the U.S. Constitution. The first takes up the repudiation of tyranny in defense of a way of being called ordered liberty in both Plato and the Federalist. The second takes up the commitment to the supremacy of intelligence over power, an order of value that is distinctly Platonic and permeates the design logic of the U.S. Constitution. Intelligence in this context is understood as …

Narrative Language Assessment And Intervention: Applications With Children With And Without Disabilities, Norah M. Almubark

USF Tampa Graduate Theses and Dissertations

Narrative is the art of conveying a sequence of causally and temporally linked events through monologic telling. Various functions can be served through narratives including sharing experiences, expressing ideas, providing entertainment, and imparting cultural or social values. Narrative language represents an authentic type of language that is useful for assessment and intervention because it can be analyzed according to content and form. The ability to use complex narrative language and produce quality narratives is associated with long-term academic and social benefits (Uccelli et al., 2019; Suggate et al, 2018). Given this crucial link, narrative language is suitable for child language …
