Towards Precision Audiology: Perceptual Profiles & Their Relation To Ecologically Valid Communication Assessments, Dana Cherri

USF Tampa Graduate Theses and Dissertations

Living in a sonic world, a person with hearing loss experiences difficulty in communicating with others. One of the reasons why some people with hearing loss do not wear hearing aids (HAs) is limited perceived benefit, which may result from HAs that are not fit using “best practices” or because the best practices fail to address individual difficulties experienced by the listener. The typical audiogram provides information regarding audibility as a function of frequency and is used to establish degree, type, and configuration of hearing loss, but does not measure the ability of an individual to process various components of …

The Impact Of Critical Illness Insurance Among Older Adults In China, Jiaosi Li

USF Tampa Graduate Theses and Dissertations

Although China has made considerable progress towards universal health insurance coverage, high out-of-pocket medical expenditures due to catastrophic illnesses (e.g., cancer, heart attack, or stroke) remain a concern. To address this concern, the Critical Illness Insurance (CII) program providing additional coverage for high medical expenditures was introduced in 2012. We combine data on the timing of CII implementation across prefecture cities in China with the China Health and Retirement Longitudinal Study (CHARLS) to examine its impact on medical expenditures, inpatient utilization, health outcomes, household consumption and savings. To account for the staggered implementation across regions, we employ the Difference-in-Differences (DiD) …

Development Of An Automated Platform For Sensing And Differentiating Vapor-Phase Btex Constituents, Jonathan Samuelson

USF Tampa Graduate Theses and Dissertations

Light aromatic hydrocarbons are an inevitable byproduct of fossil fuel extraction, refinement, distribution, and use. The four lightest and most prevalent of these are benzene, toluene, ethylbenzene, and xylene, which are known collectively as BTEX. In spite of their chemical similarity these species have markedly different effects on human health and substantially different concentrations are permitted by OSHA in workplaces and by the EPA in ambient air and groundwater. Real-time detection, identification, and quantification of these species is therefore of great importance wherever they see industrial use.This work represents the continuation and advancement of a line of research in which …

Task Progress Assessment And Monitoring Using Self-Supervised Learning, Sainath Reddy Bobbala

USF Tampa Graduate Theses and Dissertations

Robotic manipulation for cooking requires a thorough understanding of the cooking environment. The robot must understand the cooking objects and their states at each intermediate level as the process continues. To understand these states, we need frame-level annotations. To overcome this frame-level dependency, we introduce a self-supervised learning method to obtain the frame-level state representation with ”temporal video alignment” and ”contrastive learning.”In this work, we use self-supervised learning to train a model using multiple videos of the same action being performed in various settings. This model can extract frame-level embedding space and align videos via simple distance-based matching. We show …

This study explored how teachers have adapted the Montessori method in Saudi early childhood classrooms to align with Saudi socio-culture and Islamic practices. The study was framed using the socio-cultural theory. A qualitative multi-case study design was used to collect data from semi-structured interviews and on-site observations for four Saudi early childhood teachers in two Montessori classrooms in Saudi Arabia. The data were thematically analyzed manually and with NVivo software. The study results showed that the teachers encouraged children’s independence and freedom of choice in work time and during the classroom day, but limited their freedom during mini-lessons and circle …

Towards More Task-Generalized And Explainable Ai Through Psychometrics, Alec Braynen

USF Tampa Graduate Theses and Dissertations

In this work, we propose that adopting the methods, principles, and guidelines of the field of psychometrics can help the Artificial Intelligence (AI) community to build more task-generalizable and explainable AI. Three arguments are presented and explored. These arguments are that psychometrics can help by providing 1) a framework for formulating better datasets, 2) psychometric AI data that can lead to models of generalization in AI, and 3) explainable AI through more informative evaluations.

A review of psychometrics and psychological generalization is performed, along with an overview of evaluation, generalization, and explainability in AI. Various ideas are presented throughout for …

Integrating Psychopathy Into Prominent Developmental/Life-Course Theories, Eva M. Fontaine

USF Tampa Graduate Theses and Dissertations

Despite empirical research identifying psychopathy as one of the most robust predictors of criminal behavior, calls to integrate psychopathy into criminological theory have largely been unrequited. Within criminological theory, the construct of psychopathy has been proposed to best fit in the developmental/life-course (DLC) paradigm. As such, the purpose of this dissertation was to explore the theoretical integration of into psychopathy into three DLC theories: (1) Moffitt’s (1993) Dual Taxonomy, (2) Gottfredson & Hirschi’s (1990) General Theory of Crime, and (3) DeLisi’s (2009) Unified Theory of Crime. In doing so, the three studies in this dissertation employed the Pathways to Desistance …

Beyond Health And Animal Rights: A Study In Black Veganism, Wendy J. Rib

USF Tampa Graduate Theses and Dissertations

Veganism, or the avoidance of animal products, has been recognized by nutritionists and food scientists as a lifestyle choice associated with good health and lower prevalence of diabetes, obesity, hypertension, and heart disease. However, the choice to eschew all animal products is frequently more than just a diet. Many people practice veganism as part of a larger reformative social movement, seeking permanent change in food structures, advancing policies in animal welfare and transforming their everyday lives in the quest for cultural acceptance. Although the number of people who identify as vegans appears to be growing, it is often assumed that …

Heidegger And The Origin Of Authenticity, John J. Preston

USF Tampa Graduate Theses and Dissertations

Since the publication of Sein und Zeit in 1927, scholars have coupled Martin Heidegger’s reflections on authenticity with a rich tradition of thought which reminds us that philosophy can, from time to time, function as a catalyst for self-discovery. While this function is an undeniable feature of Heideggerian authenticity, I would like to suggest that it is secondary to the role that authenticity plays in Heidegger’s philosophical investigations. By analyzing the full phenomena of authenticity and tracing its first technical uses back to Heidegger’s early lectures on Aristotle, I show that Heidegger’s methodological breakthrough in the early 1920s, the development …

Longitudinal Associations Among Life Values, Alcohol Use, And Alcohol Abuse Symptoms From Adolescence To Adulthood, Connor Habecker

USF Tampa Graduate Theses and Dissertations

Investigating life value trends, the pro-social and anti-social characteristics that play a role in decision making, is an understudied field in adolescents. In addressing adolescent alcohol consumption as a public health concern, life values may provide needed background in understanding and influencing adolescent behavior toward pro-social values and away from known risk factors, such as alcohol consumption. By modeling life value trends of adolescents and the associations between each life value and the outcomes of alcohol use and alcohol abuse, there may be primordial level intervention opportunities as opposed to the current, largely ineffective, tertiary level interventions. This thesis utilizes …

Investigating Students' Interpretations Of Ecological Food Webs, Christopher Neil Grissett

USF Tampa Graduate Theses and Dissertations

To better prepare undergraduate students for current and future biological challenges, scientists, educators and researchers in the Vision and Change report recommended five core conceptual areas essential for the improvement of biological literacy, one of which is biological systems. Systems are an identified core concept that may help promote biological literacy. One example of a system that students have difficulty understanding is an ecological food web, which consists of parts or components interacting with one another to perform a given phenomenon. The intricacies of this system tend to confuse students and can produce naïve conceptions that could hinder future learning …

Preventing Variadic Function Attacks Through Argument Width Counting, Brennan Ward

USF Tampa Graduate Theses and Dissertations

Format String attacks, first noted in June 2000 [1], are a type of attack in which anadversary has control of the string argument (the format string) passed to a string format function (such as printf). Such control allows the attacker to read and write arbitrary program memory. To prevent these attacks, various methodologies have been proposed, each with their own costs and benefits. I present a novel solution to this problem through argument width counting, ensuring that such format functions cannot access stack memory beyond the space where arguments were placed. Additionally, I show how this approach can be expanded …

To Be Or Not To Be: A Tale Of Staphylococcal Gpsb, Lauren R. Hammond

USF Tampa Graduate Theses and Dissertations

There are two big drivers motivating studies into bacterial cell division. The first is a desire to understand life around us. One of the defining characteristics of life is the ability for a cell to grow and divide, and without in-depth knowledge of this process, we cannot truly understand the complexities that allow for life on this planet. The second motivator is to identify new drug targets in the ongoing fight against antimicrobial resistance. Many infectious organisms have become resistant to commonly used antibiotics, and the bacterial cell division machinery is a largely untapped essential process with many potential therapeutic …

Lord Of The Z-Rings: Uncovering The Role Of Mraz And Ftsl In Bacillus Subtilis Cell Division, Maria Louise White

USF Tampa Graduate Theses and Dissertations

Cell division is a complex and highly orchestrated process that requires careful coordination. The process of cell division in prokaryotes primarily occurs via binary fission, where one mother cell becomes two genetically identically and equally sized daughter cells. In most bacteria a key protein, FtsZ, forms a FtsZ ring (Z-ring) to mark the division site and recruit proteins involved in cytokinesis. Whilst much has been learned about the contents and assembly of the divisome in model organisms such as Escherichia coli and Bacillus subtilis factors governing the regulation of divisome are much more poorly understood. …

Design And Assessment Of A Novel Edna Survey Method For The Eastern Indigo Snake (Drymarchon Couperi), Emily K. Galbraith

USF Tampa Graduate Theses and Dissertations

1. Accurate information about species range declines is the cornerstone of effective conservation when habitat loss drives biodiversity loss. The Eastern Indigo snake (Drymarchon couperi) is an apex predator in Florida and, like many other native Florida species, is threatened by widespread habitat destruction. Environmental DNA (eDNA) monitoring of this elusive snake would provide a low-risk and low-cost approach to expand our knowledge of the species’ range and distribution.

2. We designed and tested an eDNA assay that can detect the presence of Eastern Indigo snake from soil samples of their natural habitat. This assay was …

Exploring The Vulnerability Of A Neural Tangent Generalization Attack (Ntga) - Generated Unlearnable Cifar-10 Dataset, Gitte Ost

USF Tampa Graduate Theses and Dissertations

Nowadays, a massive amount of data is generated and stored on servers and cloudsfrom various applications daily. Preventing these data from unauthorized use often becomes necessary and critical in various real-world applications. Many researchers have studied this crucial problem and developed different methods for this purpose. Among them, Neural Tangent Generalization Attack (NTGA) is one of the most efficient methods to make a dataset unlearnable, which means that the dataset is not learnable by machine learning/deep learning methods. That is, the NTGA-generated dataset is protected against unauthorized use. In this thesis, we explore the vulnerability of an NTGA-generated unlearnable CIFAR-10 …

Effect Of Hyperoxia On Cardiac Pathophysiology In Female Guinea Pig Hearts, Chayapatou Chayawatto

USF Tampa Graduate Theses and Dissertations

Hyperoxia is widely implemented in critical care and ICU patients. The administration of a high concentration of inspired oxygen to the lung can unknowingly cause hyperoxia and thereby damaging the lungs and heart due to oxidative stress. Technically, hyperoxia occurs when the patient receives PaO2 > 200 mmHg. Major research focused on hyperoxia-induced lung injury, but nothing is known on its effect on heart. Our lab is the pioneer in understanding the effect of hyperoxia on cardiovascular remodeling using mice model. Previous results show that mice under 72 hours of hyperoxia present severe cardiac pathophysiology. This research uses Guinea pigs, which …

Impact Of Language Sampling Context On Language Productivity And Complexity, Trina J. Tolentino

USF Tampa Graduate Theses and Dissertations

Language sampling is a familiar tool in the speech-language pathologist’s (SLP’s) repertoire, used to assess a student’s language ability and inform treatment targets. The current literature has several studies comparing various dimensions of language sampling context, but with relatively small samples. The goal of this study was to identify what sampling contexts elicit the most productive and complex language, thereby contributing insight into what conditions may yield the most accurate representation of a child’s language skill, as well as the resulting intervention focus.

One-thousand thirty-seven kindergarten, first-, second-, and third-grade students (mean age [years; months] ≈ 7;5; range = 5;0-10;9), …

Evaluation Of Response Modality In Online Discussion Boards, Tatiyanna A. Dunn

USF Tampa Graduate Theses and Dissertations

Since 2020, over 3 million students have enrolled in a postsecondary distance learning course (National Center for Education Statistics, 2020). One challenge in distant learning is fostering student engagement. Student engagement is a broad construct that refers to increasing contact between three pillars of education. Students, teachers, and course material. Past research has shown increasing engagement leads to improved student performance and instructor evaluations. Unsurprisingly, promoting student engagement is desirable for both students and instructors (Cobb, 2009). Discussion boards allow student engagement between themselves and Instructors while knowledge can still be tested. Few studies have evaluated the modality of student …

USF Tampa Graduate Theses and Dissertations

The work in this dissertation is presented in two parts. The first part (Chapters 3 and 4) details work relating to students’ explanations of reaction mechanisms in organic chemistry. The second part (Chapters 5 and 6) details work relating to the evaluating the uptake of research-based instructional practices in introductory chemistry, mathematics, and physics courses.

To evaluate learning of organic chemistry reactions, instructors must ask students to construct written explanations of reaction mechanisms. Written assessments should focus on what is happening and why it is happening to promote deeper student understanding. However, for instructors to gain insight into students’ understanding, …

Accelerating Multiparametric Mri For Adaptive Radiotherapy, Shraddha Pandey

USF Tampa Graduate Theses and Dissertations

MR guided Radiotherapy (MRgRT) marks an important paradigm shift in the field of radiotherapy. Superior tissue contrast of MRI offers better visualization of the abnormal lesions, as a result precise radiation dose delivery is possible. In case of online treatment planning, MRgRT offers better control of intratumoral motion and quick adaptation to changes in the gross tumor volume. Nonetheless, the MRgRT process flow does suffer from some challenges that limit its clinical usability. The primary aspects of MRgRT workflow are MRI acquisition, tumor delineation, dose map prediction and administering treatment. It is estimated that the acquisition of MRI takes around …

Deceptive Appeals And Cognitive Influences Used In Fraudulent Scheme Sales Pitches, Rafael J. Toledo

USF Tampa Graduate Theses and Dissertations

Fraud schemes exploit the complex interplay that results from utilizing deceptive appeals to activate underlying cognitive influences. This study was designed, first, to identify the deceptive appeals present in the messaging of fraudulent schemes and, second, to identify the underlying cognitive influences being exploited by the deceptive appeals utilized. Findings reveal that effectively used deceptive appeals work to keep viewers’ mental processes in a state of cognitive ease. This state allows cognitive influences--such as heuristics, cognitive biases, and the System 1 mind--to remain in control of mental processing; however, System 1 is prone to accept deceptive beliefs. The results of …

Adaptive Multi-Scale Place Cell Representations And Replay For Spatial Navigation And Learning In Autonomous Robots, Pablo Scleidorovich

USF Tampa Graduate Theses and Dissertations

Place cells are one of the most widely studied neurons thought to play a vital role in spatial cognition. Extensive studies show that their activity in the rodent hippocampus is highly correlated with the animal’s spatial location, forming “place fields” of smaller sizes near the dorsal pole and larger sizes near the ventral pole. Despite advances, it is yet unclear how this multi-scale representation enables navigation in complex environments.

In this dissertation, we analyze the place cell representation from a computational point of view, evaluating how multi-scale place fields impact navigation in large and cluttered environments. The objectives are to …

Harmony Of Difference: Theorizing Rashid Johnson's New Universalism In The Grids Of Antoine's Organ, Mark Fredricks

USF Tampa Graduate Theses and Dissertations

My reading of Antoine’s Organ, a sculptural installation created by the artist Rashid Johnson in 2016, explores the artwork as a richly textured response to the limited universalism of modernism. I argue that Antoine’s Organ is a multimodal expression which crafts a harmony of difference using the aesthetic language and forms of both visual art and music. The term “harmony of difference” is taken from and inspired by a composition of the same name by jazz musician Kamasi Washington, and is used within to describe Rashid Johnson’s counterpoint strategy to work differences with and against each other, mobilizing the grid’s …

Screening Pathological Protein Specific Antibodies As Biomarker Discovery Tools For Neurodegenerative Disease, Yitong Li

USF Tampa Graduate Theses and Dissertations

With the increase in the average life span, the incidence of neurodegenerative diseases also increases, among which Alzheimer's disease (AD) and Parkinson's disease (PD) are the two most common types of neurological disorders. AD and PD share the same pathogenic mechanism that involves a class of proteins called beta-amyloid (Aβ), which, under the induction of some factors, changes from its natural monomeric state to the oligomers containing β-sheet, which is neurotoxic and thus leads to cell damage or apoptosis. This study focused on the selection of antibodies used as biomarkers for AD and PD. The selection of antibodies was based …

The Impact Of Cannabis On Motivational Processes For Smoked Tobacco And Cigarettes, Claire M. Gorey

USF Tampa Graduate Theses and Dissertations

Cannabis and tobacco are very commonly used across the United States. Given the high prevalence of their dual use, an important health consequence of cannabis is its impact on tobacco usage rates. After all, cigarettes are a leading cause of death in the United States. Theoretical models of drug abuse suggest that cannabis cues and intoxication may be responsible for enhanced smoked tobacco/cigarette motivation. Therefore, the present research sought to assess these routes via two studies. In study 1 (validation & cross-drug cue effects), researchers validated a set of realistic cannabis images among a sample of participants residing in the …
