The Effects Of Feudalism On Medieval English Mobility: A Biological Distance Study Using Nonmetric Cranial Traits., Jonathan H. Barkmeier

USF Tampa Graduate Theses and Dissertations

Social and environmental factors play a key role in determining biocultural phenomena that can be observed on skeletal populations. Genetic markers in the form of nonmetric traits can help understand underlying questions about population movement and subsequent gene flow. During the medieval period in England, feudalism may have limited migration and created sedentary lifestyles for the peasant class who lived and worked on land owned by the nobility. By using a biological distance model, questions about the interactions between rural and urban populations, as well as the restrictive economic system that was in place during the Middle Ages, can be …

Journey Mapping The Minority Student’S Path Toward Genetic Counseling: A Holistic Picture, Tatiana E. Alvarado-Wing

USF Tampa Graduate Theses and Dissertations

Reasons for limited ethnic and racial diversity among genetic counselors in the United States may be elucidated through better understanding the experiences of minority students who are attending genetic counseling graduate programs as well as recent graduates. Semi-structured interviews were conducted with minority participants using Journey Mapping to elicit touchpoints that positively or negatively impact success at varying points on the path to becoming a genetic counselor. Touchpoints with negative impacts include; late awareness of the profession, observing the lack of diversity in the field, the financial burden of the application process, and microaggressions from peers, program leadership, and clinical …

Toward Culturally Relevant Emotion Detection Using Physiological Signals, Khadija Zanna

USF Tampa Graduate Theses and Dissertations

Research shows that emotional distress has a statistically significant impact on a student’s grade point average and intent to drop out of college. Because students of different races have varying college experiences, it is important to understand the emotional experiences of different racial groups to better support students’ needs and academic success. In this work, we explore several physiological responses to ten different emotional stimuli captured from 140 students. We employ unsupervised learning via the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm and supervised learning via Random Forests and Support Vector machines to analyze clustering partitions and classification …

Synthesis Of A Targeted Ph Responsive Nanoparticle For Controlled Release Of Actinomycin D, Alejandro Jesus Gonzalez

USF Tampa Graduate Theses and Dissertations

Out of all cancer diagnosis’s, lung cancer has the highest mortality in both sexes making it the leading cause of cancer deaths. Current therapeutic and clinical methods fail to successfully treat the disease, contributed to the development of multi-drug resistance (MDR). Hence, new therapies are needed that can exploit the tumor microenvironment (TME) to target Cancer Stem Cells (CSC). CSCs constitute a key population of the TME, promoting hypoxia, low intracellular pH, and angiogenesis. Actinomycin D (ACD) is a potent CSC inhibitor, but due to its high toxicity and lack of specificity towards cancer cells presents a need for a …

Evaluating Effects Of Cancer Genetic Counseling On Several Brief Patient Impact Measures, Alyson Kneusel

USF Tampa Graduate Theses and Dissertations

Many outcomes for assessing cancer genetic counseling (GC) utility have been proposed, with few studies evaluating multiple, theory-based, brief patient-reported experience and outcome measures simultaneously as part of a single study. We conducted a pilot study in which patients seen for pre-test cancer GC took a survey before and after their GC session to evaluate the session’s impact on multiple patient impact measures and assess the relationship between these measures. Measures based on the self-determination theory (SDT) assessed three basic needs including: 1) perceived autonomy support, 2) relatedness to the provider, and 3) competence to make a decision. SDT posits …

Instrumentalization Theory: An Analytical Heuristic For A Heightened Social Awareness Of Machine Learning Algorithms In Social Media, Andrew R. Miller

USF Tampa Graduate Theses and Dissertations

New innovations in information management and communication technologies have produced technological assemblages which have radically altered the way people socialize and interact with the world. The most significant and ubiquitous of these technologies is what is colloquially referred to as ‘machine learning.’ Like most, if not all, technologies, machine learning models are neither wholly good nor bad. Their functional ethics are largely determined by the context in which they are employed. However, their ubiquity demands that we develop a heightened social consciousness of the way machine learning simultaneous constrains, manipulates and democratizes social processes. In order to develop better social …

The Short-Term Effects Of Different Removal Methods Of Urochloa Maxima, Guinea Grass, On Acoustic Complexity, Connor D. Wagner

USF Tampa Graduate Theses and Dissertations

Invasive exotic species are one of the biggest threats to ecosystems in Florida, and land managers instill numerous methods to try and control them. Mechanical treatment, such as mowing, and chemical treatment, such as foliar spraying with the herbicide glyphosate, are two methods of invasive species removal. While the effectiveness of these management practices has been thoroughly observed and studied, little research has been done on their impacts to the ecological soundscape. The ecological soundscape refers to all biotic and abiotic sounds produced in the environment. Species presence and acoustic complexity was measured before and immediately following a mechanical and …

“I Woke Up To The World”: Politicizing Blackness And Multiracial Identity Through Activism, Angelica Celeste Loblack

USF Tampa Graduate Theses and Dissertations

Drawing from in-depth, semi-structured interviews with 21 Black multiracial students, this project explores the extent to which processes of racial socialization and racialization can differentially inform how Black multiracial students navigate and experience involvement in

Black student and activist organizations. It unpacks the ways that anti-Black racialization and racism, experienced in the college setting, can motivate Black multiracial students’ involvement in student organizations. Moreover, it highlights the ways in which involvement in anti-racist activism and Black student organizations can impact Black multiracial students’ understandings of blackness, multiraciality, and identity more broadly. To operationalize the long term impacts of Black organizational …

Testing Glutathione-S-Transferase Mu 1 (Gstm1) In Protecting Retinal Pigment Epithelium Cells From Oxidative Stress, Inyoung C. Garner

USF Tampa Graduate Theses and Dissertations

Currently, the most widely available treatment for wet age-related macular degeneration (AMD) involves the intraocular delivery of biopharmaceuticals, such as anti-VEGF therapy. Drawbacks of this treatment includes a short-term efficacy, requiring repeated injections with additional risks, and a limited availability of options for non-responders. Furthermore, there are no treatments available for patients diagnosed with dry-AMD. The drawbacks and limitations of current therapies represent a need for more effective and permanent therapy as the prevalence of the population affected by AMD is growing. Antioxidant gene therapies are one solution to these implications, protecting the cells from oxidative stress which is one …

The Development And Testing Of The Genetic Counseling Communication Checklist (Gcc): A Novel Process Measure, Katherine N. Hehmeyer

USF Tampa Graduate Theses and Dissertations

Given that genetic counseling (GC) is a discipline that relies on communication to help people understand and adapt to the genetic contribution of disease, a practical method of comprehensively documenting GC communication strategies is needed to better understand the communication strategies utilized by genetic counselors and the variability that exists within the process. To this end, we created a novel process measure called the Genetic Counseling Communication Checklist (GCC), utilizing previously validated measures, communication/counseling theories, and research findings. Two researchers independently coded six video-taped mock GC sessions using the GCC. Following each session, the GCC was further modified to improve …

Essays On The Disposition Effect, Matthew Henriksson

USF Tampa Graduate Theses and Dissertations

This dissertation contains two essays that shed new light on the disposition effect – that is, the tendency for investors to be especially eager to realize gains over losses. The first essay combines county-level natural disaster data with individual investor transactions to document an increased disposition effect for investors impacted by a natural disaster. This effect is increasing in disaster severity and decreasing in the length of time following the event, suggesting that extreme natural disasters can significantly influence investor behavior, especially in the short term. These findings are not explained by liquidity needs, tax incentives, or informed trading. The …

Elemental Climate Disaster Texts And Queer Ecological Temporality, Laura Mattson

USF Tampa Graduate Theses and Dissertations

This thesis approaches climate disaster texts as an opportunity to challenge constructions of the body, space, and time. Developed from embodied experiential knowledge about hurricanes, my work will explore how climate disasters can teach us to reimagine human-nature relationships. In my two analysis chapters, I use critical textual analysis and autoethnography to challenge particular representations of the human-nature relationship as a binary between nature and culture. By intervening in the nature-culture binary, I theorize queer ecological temporality as an opportunity to reveal and challenge constructions of nature and time. Working at the intersections of queer and ecocritical theory, this thesis …

Mystic Medicine: Afro-Jamaican Religio-Cultural Epistemology And The Decolonization Of Health, Jake Wumkes

USF Tampa Graduate Theses and Dissertations

The underlying motivation for this thesis is the position that colonialism, or coloniality, continues to thrive as an ideological and institutional framework all over the world, to the detriment of the majority of the population of the earth, and particularly of indigenous peoples and the African diaspora. Thus, what is sought here is a decolonization both of mind and institutions. Looking at the case of Jamaica, one can see how coloniality continues to undermine the beliefs, behaviors, institutions, and overall well-being of the majority African-descended population of the island in many ways both culturally and economically. I narrow my focus …

Kinesthetically Speaking: Human And Animal Communication In British Literature Of The Long Eighteenth Century, Dana Jolene Laitinen

USF Tampa Graduate Theses and Dissertations

While scholars have studied talking animals in British children’s literature of the long eighteenth century, little attention has been given to cross-species conversations. Thus, my research starts with the following questions: what does it mean when humans talk to animals in literary texts? What do representations of interspecific communication in eighteenth-century British literature accomplish? Interspecific communication in the literary works of this study may be understood in the context of the philosophy of sensibility’s debt to French Renaissance humanist Michel de Montaigne, particularly his arguments about animal semiosis in An Apology for Raymond Sebond. I argue that interspecific conversations challenge …

The Role Of Financial Insecurity And Expectations On Perspectives Of Mental Health Services Among Refugees, Jacqueline M. Siven

USF Tampa Graduate Theses and Dissertations

This dissertation examines how perspectives of mental health among refugees are situated within the realities of the refugee resettlement system, a population for which information on this issue is quite limited. Through in-depth interviews and participant observation with Congolese refugees and non-Congolese refugee-serving professionals in a major Florida city, this dissertation examines how perceptions of mental health and mental health services among refugees were affected by financial insecurity and disparities in expectations. Local Congolese refugees expected the American Dream; they believed that once they arrived they would find prosperity through hard work. Instead they experienced frustration and distress because the …

Predictors Of Premature Discontinuation From Behavioral Health Services: A Mixed Methods Study Guided By The Andersen & Newman Model Of Health Care Utilization, Shawna M. Green

USF Tampa Graduate Theses and Dissertations

Emerging adults, ages 18 to 25, demonstrate high prevalence of behavioral health illnesses, yet infrequently access treatment. For those who do access care, premature discontinuation rates from treatment are high, ranging from 30 to 50 percent. For the emerging adults who initiate contact with the systems of care by attending at least one session of therapy, there is an opportunity to engage them in treatment and prevent negative health outcomes in adulthood. This mixed methods study used the Andersen & Newman (1973) model of healthcare utilization as a guiding framework to explore and examine premature discontinuation from public sector behavioral …

Structure Based Inhibitor Discovery Targeting Multiple Β-Lactamases Involved In Antibiotic Resistance, Afroza Akhtar

USF Tampa Graduate Theses and Dissertations

Emergence of antibiotic resistance severely threatens the existing medication and prevention facilities against an over increasing range of infections caused by a wide range of microbes. Specifically, treatment of Gram-negative bacterial infection is getting more problematic due to their resilience against β-lactam antibiotics: the most commonly prescribed antibiotics in clinical settings. Production of β-lactamases is the most prevalent mechanism utilized by various Gram-negative pathogens to become resistant to the β-lactam antibiotics e.g, penicillins, cephalosporins, carbapenems and monobactams. These enzymes mediate their function through hydrolyzing the core β-lactam ring present in all β-lactam antibiotics which causes opening of the ring and …

Algorithms To Profile Driver Behavior From Zero-Permission Embedded Sensors, Bharti Goel

USF Tampa Graduate Theses and Dissertations

In this dissertation, we design algorithms to profile driver behavior from zero-permission sensors embedded in modern smartphones and wearables. These sensors are typically the accelerometer, gyroscope, magnetometer, pressure sensor and a few more than are now available in most modern smartphones and wearables. In order to profile driving behavior, we devised algorithms for detecting distraction while driving due to the use of modern-day smartphones (e.g., calling, texting and reading while driving) in real-time.

To do so, we conduct an experiment with 16 subjects on a realistic driving simulator, where each subject, where each subject carries a smartphone and a wearable …

Differential Reinforcement Without Extinction: An Assessment Of Sensitivity To And Effects Of Reinforcer Parameter Manipulations, Hannah Lynn Macnaul

USF Tampa Graduate Theses and Dissertations

Individuals with an Autism Spectrum Disorder (ASD) often engage in problem behavior (e.g., aggression, property destruction, self-injurious behavior; Horner, Carr, Strain et al., 2002) that may limit access to traditional social and education settings, impact their health, and pose a risk to their safety and the safety of others. One of the most common interventions used to treat problem behavior is differential reinforcement of alternative behavior (DRA; Cooper, Heron, & Heward, 2007), which are often used in combination with other interventions such as extinction (Shirley, Iwata, Kahng, Mazaleski, & Lerman, 1997). However, implementation of extinction may pose an ethical dilemma …

USF Tampa Graduate Theses and Dissertations

St. Martin’s Marsh Aquatic Preserve (SMMAP) is a 28,461 acre (115.18 km2) preserve located on the coast of Citrus County, Florida, USA. There has been no published research that focused on coastal change on this unique coast. This thesis research focuses on coastal land cover change that has occurred within the preserve from 1988 to 2018. Multitemporal Landsat images were classified using a support vector machine (SVM) classification, while changes in vegetation were evaluated using the normalized difference vegetation index (NDVI). Field research was conducted to examine nineteen sites for classification training and test data and notes on habitat composition. …

Roots In Antiquity: A Comparative Study Of Two Cultures, Lara Younes Freajah

USF Tampa Graduate Theses and Dissertations

This study was conducted with the goal to provide an in-depth analysis of the analogous qualities of two very distinct yet similar cultures: the Arab and Sarakatsan cultures, with a particular focus on personal matters that deal with family and kinship. Despite the difference in religions, both groups demonstrate a substantive set of similar traits especially in terms of the interactions, dynamics, and functionality of family relations in addition to the highly-esteemed values that dictate everyday conduct. As a first-generation Arab Muslim who immigrated to the United States, I use the culture in which I am entrenched as a basis …

Legitimizing Violence: Functional Similarities Of The Religious And The Secular Violence, Tahir Topal

USF Tampa Graduate Theses and Dissertations

As a consequence of the separation between religion and politics, known as secularism, the discussion about violence has also been divided into two main categories –Religious Violence and Non-Religious Violence– in the modern Western academia. The tendency of the leading scholarly work in the discourse of "religious violence" is that "religion" is inclined to be violent more than secular institutions for several reasons. Therefore, the state's violence, as being secular, steps in to bring peace. And the foundational cause of the theories relies heavily on the essential differences of "religion" and the secular. With counter-arguments, William T. Cavanaugh and Talal …

USF Tampa Graduate Theses and Dissertations

There are numerous ways in which heritage can be managed and presented to the public, such as: physical museums, virtual museums, tours of historic homes, and archaeological parks. For this project, I participated in and observed heritage preservation management under a unique partnership of the City of Safety Harbor recreation department and the Safety Harbor Museum Board in Safety Harbor, Florida. My internship was with the Safety Harbor Museum and Cultural Center, primarily under the direction of Shannon Schafer and Christine McWilliams. My initial focus was assisting these two groups with projects specific to the needs of the museum. I …

Villains Or Vermin? The Differential Effects Of Discrimination And Dehumanization On Immigrant Cardiovascular Responses, Mona El-Hout

USF Tampa Graduate Theses and Dissertations

Immigration has been pushed to the forefront of a national political debate, and immigrants are commonly portrayed as villains and vermin looking to invade and infest Western nations. These negative portrayals of immigrants may have negative implications for immigrant health outcomes. Among other negative health outcomes, studies have found that immigrant cardiovascular disease rates increase with time spent in the U.S. This phenomenon of decreasing immigrant health with extended U.S. residency has been labeled “the immigrant health paradox”, and discrimination has often been posited as a possible explanatory factor. In addition to discrimination, immigrants are often the targets of dehumanization, …

Orders Of Normativity: Nietzsche, Science And Agency, Shane C. Callahan

USF Tampa Graduate Theses and Dissertations

In this dissertation I set out to address the “scope problem” in Nietzsche scholarship. In the secondary literature, the scope problem is characterized as a problem for Nietzsche, who seems deeply skeptical about nearly every item of his inherited western metaphysical toolkit. If his skepticism about western metaphysics penetrates all dimensions of his thought, how can he motivate a reader to also reject western metaphysics without himself committing to some of it? I stipulate that answering the scope problem means explicating what Nietzsche views as the general source of normativity—it is there that we can understand the resources Nietzsche is …

The Effects Of Socioscientific Issues On Informal Reasoning And The Transference To Controversial Issues In A Social Studies Context, Thomas J. Dolan

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine if informal reasoning skills associated with socioscientific issues (SSI) transferred to controversial issues in a social studies context. The principal researcher developed three controversial issues derived from social studies education to create social studies context issues (SSCI). This acronym has been termed by the principal researcher, as controversial issues in social studies have not been evaluated beyond the social studies classroom. Twenty-one, fifth grade students participated in this three-month study, which featured three specific SSI units (A Need for Speed? – speed limit reduction, Roller Coaster Ban – preventing injuries to children, …

Isotope-Based Methods For Evaluating Fish Trophic Geographies, Julie L. Vecchio

USF Tampa Graduate Theses and Dissertations

Data on the movement and diets of fish during a variety of life stages are important inputs to fisheries stock assessments and marine ecosystem models. Stable isotopes may provide previously inaccessible information on movement and diet of a variety of managed and forage fish species. Here I used several novel means of interpretation for stable isotope data to infer diets and movements of several important fisheries species over both short (weeks to months) and long (lifetime) timescales. To calculate a constant partitioning offset (CPO) between the δ¹⁵N of muscle and of liver tissue, I conducted a literature search …
