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 …

The Joint Effects Of Sleep And Pain, And Moderations By Work Characteristics, Christina Xuong Mu

USF Tampa Graduate Theses and Dissertations

Reactivity describes interindividual differences in the physiological or emotional responses following an antecedent stressor. For instance, higher stressor reactivity to shorter sleep (i.e., those who report greater stressor severity following shorter-than-usual sleep) and higher negative affective reactivity to stressors (i.e., those who report more negative affect following a stressful event) have worse mental and physical health. Pain reactivity to shorter sleep is a novel concept that describes differences in pain responses following a night of shorter-than-usual sleep. Higher pain reactivity to shorter sleep means that individuals report more pain locations or higher pain severity following shorter-than-usual sleep the previous night, …

Sargassum In The Florida Keys: Assessment Using High Resolution Remote Sensing, Sarah “Sully” Sullivan

USF Tampa Graduate Theses and Dissertations

Pelagic Sargassum in the Atlantic Ocean, one type of floating macroalgae, has increased in biomass and extent since 2011, bringing environmental, health, and economic issues to coastal communities. The introduction of large quantities of Sargassum to the Florida Keys, a tourism hub renowned for coral reef and marine diversity, poses a potentially devastating threat. Currently, Sargassum mats are widely monitored using medium resolution satellite imagery such as those collected by the Moderate Resolution Imaging Spectroradiometer (MODIS, 1km) and spectral band difference algorithms such as the Alternative Floating Algae Index (AFAI), but the resulting maps lack the detail and nearshore certainty …

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 …

Exploring The Dynamics Of September Fish Spawning On The West Florida Shelf Through The Dna Barcoding Of Fish Eggs, Keith G. Keel

USF Tampa Graduate Theses and Dissertations

Identifying spawning areas for economically and ecologically important fishes is critical for fisheries conservation and ecosystem-based management. Additionally, monitoring the spawning dynamics of fishes is increasingly important as temperatures and oceanic conditions change. I used genetic barcoding to identify fish eggs collected across the West Florida Shelf (WFS) during September of 2013, 2014, and 2019. Fish eggs were collected on National Oceanic and Atmospheric Administration (NOAA) Southeast Area Monitoring and Assessment Program (SEAMAP) ichthyoplankton cruises using a Continuous Underway Fish Egg Sampler (CUFES). Analysis of 4,400 fish eggs from the three years resulted in the identification of 83 unique species …

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 …

Uprooted, Displaced, Resilient: Kosovar Women’S Narratives Of Organizing For Survival During The Kosovo War, Erjona Gashi

USF Tampa Graduate Theses and Dissertations

The goal of this dissertation is to foreground Kosovar women’s narratives and organizing properties during the Kosovo War. I examine the overlooked gendered roles and day-to-day lived experiences of Kosovar women, survivors of the Serb genocide, political violence, and oppression, and investigate their organizing properties during the Kosovo War (1998-1999). In acknowledging women’s plurality of experiences and perspectives, I challenge the currently pervasive and monolithic narrative of women as passive victims of war present in scholarship in organizational communication and instead make overt the narrative of women as critical organizational actors that sustain lives during and after the war. Using …

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 …

Organizing Queer Civil Rights Movements: Pride Parades And Communicative Dilemmas, David J. Dooling

USF Tampa Graduate Theses and Dissertations

Pride parades (“Pride”) are sites of communicative tension for the queer community. While the political origins of queer civil rights practiced widespread resistance to institutional heteronormativity and homophobia, Pride is a space where business owners, community stakeholders, and activists debate the political utility of queerness. This dissertation employs queer and sociomaterial theoretical traditions, and autoethnographic methodological approaches to explore the communicative strategies of Pride organizers—individuals who create, coordinate, and conceptualize the display of sexuality and gender in the public sphere. I draw on tension-centered approaches to organizational communication, feminist dilemmatic theorizing, and co-sexuality to investigate power-laden structures and decision-making in …

“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 …

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 …

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 …

Seminoles, Soldiers, And Settlers: Identity And Power On The Florida Frontier, Jean Louise Lammie

USF Tampa Graduate Theses and Dissertations

This project uses an historical archaeological approach to analyze the processes of cultural negotiation between disparate social groups living in a remote borderland in the early to mid-nineteenth centuries. Florida, first colonized by the Spanish in the 1500s was passed to the United States in 1821 as part of the young nation’s nascent Manifest Destiny. The Seminoles experienced multiple colonial conflicts, dealt with new diseases, and selected aspects of European culture to incorporate into their daily practices of lifeways.

Archaeological studies of culture change tend to focus on the product of colonial interactions rather than the processes of change that …

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 …

Elementary level English/Spanish speaking children were taught local ecological knowledge (LEK) during a STEM summer program in a city in Southwestern Florida. The use of participant observation, group interviews with the students, and interviews with the educators allowed for an in-depth analysis of the program and the established goals. This study provides insight …

Comparative Analysis Of Time Series Models On U.S. Stock And Exchange Rates: Bayesian Estimation Of Time Series Error Term Model Versus Machine Learning Approaches, Young Keun Yang

USF Tampa Graduate Theses and Dissertations

This study presents a comparative analysis of contemporary applications of time series models, focusing on the Bayesian approach. In contrast to many nonparametric studies, the Bayesian approach circumvents the common issue of bandwidth selection by offering systematic estimation and avoiding ad hoc methods. Specifically, we delve into the Bayesian approach for estimating the autocovariance function of a time series model’s error term. Traditional time series models often make the unrealistic assumption of a constant error term. Furthermore, models such as autoregressive conditional heteroskedasticity (ARCH) and general autoregressive conditional heteroskedasticity (GARCH) address the limitation of constant variance by assuming an autoregressive …

Rate Of Latine Caregiver Involvement In The Well-Being Promotion Program Using Culturally And Linguistically Responsive Communication Practices, Nicole G. Pacateque Rodriguez

USF Tampa Graduate Theses and Dissertations

Latine and Hispanic youth tend to have higher rates of mental health disturbances in school compared to non-Latine youth, yet they are less likely to receive support (Alegría et al., 2008). Additionally, Latine families are more likely to terminate treatment for youth early due to negative stigma, lack of culturally appropriate mental health care, racial and ethnic discrimination, and linguistic and cultural barriers involving care (Kapke & Gerdes, 2016). Best practices in school-based mental health services often involve including caregivers in care (Hoover et al., 2019) as it can benefit outcomes of treatment for the child (Richards et al., 2007). …

The Thermodynamics And Structure Of Tumor Suppressor P53 And Helical Mutants Binding To Inhibitors Mdm2 And Mdmx At The Primary And Secondary Sites, Pirada Serena Higbee

USF Tampa Graduate Theses and Dissertations

p53 is an intrinsically disordered protein that is a tumor suppressor. The transactivation domain is split into two parts (TAD1 and TAD2). These TADs bind to inhibitors MDM2, and a homolog, MDMX, but TAD1 binds with greater affinity. MDM2 is an E3 ubiquitin ligase that leads to the degradation of p53. MDMX is not an E3 ubiquitin ligase, but it does prevent p53 from binding to DNA, thus preventing its tumor suppressor role.

Previous research showed that increasing p53 helicity by mutating prolines to alanines increased p53's helicity but not the length of the helix. The increase in helicity increased …

Effectiveness Of Contact-Based Strategies On Improving Mental Illness Stigma And Help-Seeking Behaviors Within Families, B. Michelle Wilks

USF Tampa Graduate Theses and Dissertations

Adolescence is a developmental period that often involves extreme physical, psychological, and emotional changes and sometimes the experience of significant personal and social challenges. In addition to these challenges, youth are trying to find their place in the world and developing their identities, which depend heavily on their relationships with others. Adolescents who struggle with their mental health and also fail to develop meaningful connections with others, tend to have poor self-esteem, self-isolate, are ostracized by others, and have a poor social self-concept, all of which are associated with poor mental health and increased risk for suicidal ideation. The impact …

Individual Behavioral Modeling Across Games Of Strategy, Logan Fields

USF Tampa Graduate Theses and Dissertations

An individual’s actions in a particular environment and with specified resources can reveal their decision-making tendencies and patterns, and by analyzing the variations in cognitive traits among individuals, it may be possible to identify trends that can foretell their future behaviors. This can be a powerful tool in various fields including cognitive modeling, player analytics, computer security, and threat detection. Collectible card games are a fruitful test space for studying cognitive differences in decision-making, as they can have clearly defined and replicable environments and large player bases. As such, in this work, I explore the potential of using two virtual …

Sociocultural Factors, Definitions, And Experiences Of Intimate Partner Violence Among Latina And Hispanic Women, Vanessa Centelles

USF Tampa Graduate Theses and Dissertations

Intimate partner violence (IPV) is a pressing public health concern in the United States (US), particularly for women. Some studies have shown that Hispanic and Latina women are at an elevated risk of experiencing IPV due to a notable passiveness of violence among traditional Hispanic and Latina women. Thus, it is crucial for research to examine the effects of sociocultural variables—such as cultural orientation, gender norm beliefs, and ethnic identity—on IPV within this demographic, particularly for women in the US. Furthermore, while the experiences of IPV victimization among Hispanic and Latina women have begun to be recognized in the broader …

Stereotyped Non-Stereotypicality: Exploring Positive Effects Of Non-Stereotypical Gender Portrayals On Consumer Perceptions, Veronika Ponomarenko

USF Tampa Graduate Theses and Dissertations

This research attempts to identify contexts where non-stereotypical gender portrayals may have positive effects on consumer perceptions. It tests the perceived self-expressiveness of non-stereotypical gender portrayals as the mediating mechanism behind these effects as well as other alternative mechanisms in a comprehensive experiment. The analysis results show that an interpretation of gender through the theoretical lens of extravagance rather than self-expressiveness seems to be more appropriate. This study also introduces an overarching theoretical framework of metacognitive experiences that may explain the processes driving the effects of non-stereotypical gender portrayals on consumer perceptions. Finally, this research explores different types of gender …
