Imaging perfusion/vascular abnormalities in these patients often plays a vital role in clinical diagnosis and treatment decisions.

Vascular diseases typically present as macrovascular or microvascular diseases. Microvascular disease (MVD) refers to vascular disease primarily affecting the arterioles, venules, and capillaries in various organs. Furthermore, MVD is widely found …

The Science Of Guessing: Critiquing Ancestral Estimation Through Computer Generated Statistical Analysis Within Forensic Anthropology In A Real-World Setting, Christopher J. Turner

USF Tampa Graduate Theses and Dissertations

Research on current methods of ancestral estimation must reflect on biological heritage to aid in human identification. Using modern craniometrics methods, how do individuals with a varied biological history affect ancestral estimation? Today, the most used and reliable methods for craniometrics analysis for ancestral estimation in forensic anthropology are computer programs. Two programs are analyzed in this study, Fordisc 3.0 and 3D-ID. The analysis of these computer programs goes beyond the controlled environment provided by an osteological collection. These remains of individuals were unidentified, only to be identified later, through academic research, police work, and public outreach. The selection of …

American Military Service And Identity: From The Militia To The All-Volunteer Force, Andrew C. Sparks

USF Tampa Graduate Theses and Dissertations

The purpose of this project is to examine the growth of the American military service regimes along with how the American State used those regimes to construct American identity. To accomplish this, this project looks at the length of American war as a dependent variable from the types of war fought and the military service regimes. Over the course of this study, we examine four distinct eras: the militia regime, the coercive regime, the Peacetime Draft, and the All-Volunteer Force. Each of these correspond to various types of identity development, which include individual state, regional/national, international, and retrospective identity, respectively. …

Data-Driven Analytical Modeling Of Multiple Myeloma Cancer, U.S. Crop Production And Monitoring Process, Lohuwa Mamudu

USF Tampa Graduate Theses and Dissertations

Globally, cancer disease is a major health issue causing a lot of deaths. The duration of time an individual diagnosed with a particular type of cancer survives has become a major area of research concern. The Kaplan Meier and Cox Proportional Hazard (Cox-PH) model have been a traditionally used method for survival analysis of cancer data. These techniques of cancer survival analysis are developed from nonparametric and semi-parametric approaches, respectively, which are not as robust as a parametric approach. In this dissertation, we proposed a new method of cancer survival analysis based on a parametric approach using multiple myeloma cancer …

Parallel Computation Of Feynman Path Integrals And Many-Body Polarization With Application To Metal-Organic Materials, Brant H. Tudor

USF Tampa Graduate Theses and Dissertations

The Space Research Group is a computational outfit, and so the work presented herein will reflect that. Much of our simulation code is developed in-house and so what follows is a small exploration of that development—although the physics underpinning our software development is never ignored for long. Following the programming centric work, the code and the physics are put to the test. The final chapter describes a scientific endeavor in which a new, robust force field has been validated. Indeed, the new potential has taken a first step in proving itself by making accurate predictions in what have historically found …

Theory And Application Of Dielectric Rod Antennas And Arrays, Gabriel Saffold

USF Tampa Graduate Theses and Dissertations

Dielectric rods have been used for many years as waveguides and radiators. Their low loss as a transmission line and tendency to radiate at discontinuities have proven useful in applications ranging from fiber optic cables to naval fire control radar. Although this technology is well es- tablished, advances in additive manufacturing techniques and associated materials combined with the ubiquity of wireless communications and their shift to higher frequencies have generated re- newed interest in dielectric rods. Dielectric rod antennas have moderate gain and less conductive loss at higher frequencies. Similar to other surface wave antennas, they can achieve broadband performance.This …

Fuer Kaiser Und Heimat: Svetozar Borevic, South Slav Habsburg Nationalism, And The First World War, Sean Krummerich

USF Tampa Graduate Theses and Dissertations

This dissertation examines the function of national identity and the degree to which it is a recent development, particularly in the region of the Balkan Peninsula populated by the South Slav (Serbian, Croatian, Slovenian) peoples. The study examines the question of whether in the period prior to 1918, when much of this territory was part of the multinational empire of Austria-Hungary, was it possible for individuals to be entirely loyal to both their national group and to the construct of the multinational state simultaneously.

In order to answer this question, the dissertation surveys the career of Svetozar Boroević von Bojna …

On The Application Of Recursive Nonlinear State Transformations And Nonlinear Feedback To Enable Continuous Thrust Spacecraft Orbital Rendezvous, Parisa Khosravi

USF Tampa Graduate Theses and Dissertations

This dissertation presents a method to address exact feedback linearization problems based on the recursive application of approximate feedback linearization techniques. An approximate feedback linearization method is applied recursively to systems which are known to be an exact feedback linearizable to obtain a family of exact solutions up to the ρ-th degree utilizing the null space that appears as part of the computations. The coordinate transformation and feedback parameters are computed symbolically using a one-step approach in multi-stage form. This algorithm is algebraic and computationally simpler than solving the set of nonlinear partial differential equations. We employ the approximate feedback …

A Barker Type Approach For Measuring And Interpreting Vle Of Polymer Mixed Solvent Systems, Vaishali Jain

USF Tampa Graduate Theses and Dissertations

The environment around us has a great impact on human health. A polluted environment can adversely impact human health and cause diseases like cancer, skin diseases, breathing problems and many more and hence altering the quality of life. Hence it is very important to develop sensors that can efficiently detect these harmful substances from environment. Volatile organic compounds (VOCs) are carbon-based chemical substances that are volatile even at ambient temperature and pressure conditions which enter the atmosphere through industrial processes, building materials, etc.

Acoustic wave devices can detect very low concentrations (ppm, ppb) of organic compounds in the environment. A …

Directing Attention In Second Language Phonological Contrast Learning, Laura Conover

USF Tampa Graduate Theses and Dissertations

Why are some people better at learning new languages than others? There is a rich body of research examining this issue from multiple perspectives and at all levels of language. This study attempts to add to that knowledge at the most fundamental level of language by examining potential influences on the learning of novel phoneme contrasts. The purpose of this study was to explore whether individual differences in attentional capabilities would help adults learn a non-native phonological contrast, and whether providing explicit directions that would guide the learners’ attention could help boost their performance. VCV recordings of the Thai /p/ …

Hyperoxia-Induced Cardiac Pathophysiology In Guinea Pig Hearts, Zain Ul Abidin

USF Tampa Graduate Theses and Dissertations

Hyperoxia, is regularly introduced to critically ill patients in ICU. Nevertheless, recent studies have shown the negative effects of this treatment on patients in critical care, including increased rates of lung and cardiac injury and thereby high in-hospital mortality. Large part of the literature related to hyperoxia was majorly focused on lung injury, with no or minimal investigations on cardiac injury. Our lab is the first to investigate the effect of hyperoxia on cardiac pathophysiology in mice and showed that mice exposed to hyperoxia for 3 days demonstrated brady-arrhythmia, cardiac hypertrophy, QTc prolongation along with other electrical remodeling and functional …

Combination Of Time Series Analysis And Sentiment Analysis For Stock Market Forecasting, Hsiao-Chuan Chou

USF Tampa Graduate Theses and Dissertations

The goal of this research is to build a model to predict trend of financial asset price using sentiment from news headlines and financial indicators of the asset. Objective of the model is to conclude good results but also to minimize the difference between predicted values and actual values. Unlike previous approaches where the sentiments are usually calculated into score, we focus on combination of word embedding of news and financial indicators due to nonavailability of sentiment lexicon.

One idea is that the sentiment of news headline should have impact on financial asset val- ues. In other words, it would …

Dismantling Hegemony Through Inclusive Sexual Health Education, Lauren Wright

USF Tampa Graduate Theses and Dissertations

This thesis examines the process of developing a sexual health education curriculum that is not only tailored to the unique needs of foster-engaged young women, but also those who may experience further marginalization from other mainstream programs due to their race, sexual orientation, gender identity, and/or their religious beliefs. In conjunction with the Adolescent Sexual Health Education and Research (ASHER) Program, I helped develop a sexual health education curriculum, "Choosing Myself," targeted toward foster-engaged young women and young women (ages 13-24) in the state of Florida. "Choosing Myself" is intended to be an inclusive program that empowers participants, improves their …

Nietzsche On Criminality, Laura N. Mcallister

USF Tampa Graduate Theses and Dissertations

In Nietzsche scholarship, little has been done regarding Nietzsche’s reflections on penology and criminology. This dissertation aims to critically examine Friedrich Nietzsche’s thoughts on justice, punishment, and the criminal and to show that his interest in these topics runs throughout his writings. Nietzsche attacked the tradition of Western justice theory and the idea that justice consists in giving each their due. I argue that in place of this notion of justice, he puts forth a non-metaphysical, naturalistic account of justice that refuses to judge and hold man accountable. In addition, I explicate Nietzsche’s passionate critique of punishment, which stops short …

Sulfate Optimization In The Cement-Slag Blended System Based On Calorimetry And Strength Studies, Mustafa Fincan

USF Tampa Graduate Theses and Dissertations

Optimization of sulfur trioxide (SO³) content is typically conducted for plain cements (OPC-based) paste or mortar systems using compressive strength testing and isothermal calorimetry for quality control. The objective of these procedures is to ensure adequate strength and set properties by controlling the time of occurrence of the aluminate peak by adjusting the SO³ content by incremental addition of sulfate in the form of hemihydrate at three or more levels, at the same time attempting to maximize either strength or heat of hydration at 1 and 3 days. The inclusion of supplementary cementitious materials such as blast …

Insights Into The Role Of Metal Composition, Preparation Method, Catalyst Pretreatment For Application In The Development Of Catalytic Reforming Materials For Intensified Conversion Of Biogas Sourced Methane, Yetunde Oluwatosin Sokefun

USF Tampa Graduate Theses and Dissertations

The combustion of fossil fuel sources, crude oil, natural gas, and coal to meet the world’s energy demand has contributed to the increased emissions of carbon dioxide and other harmful gases to the environment. These negative contributions and their resulting impact on environmental conditions and several reports of their peak production and eventual depletion have influenced the need for cleaner and alternative energy production using renewable energy sources.

From the available renewable energy sources ranging from wind, solar, hydrothermal, geothermal, and biomass, biomass is an attractive option because it is largely ubiquitous and a waste commodity that can be converted …

Jewish Early Adolescent Perceptions Of Their Positive Youth Development, Identity Development, And Purpose, Lauren B. Kurnov

USF Tampa Graduate Theses and Dissertations

This qualitative study explored Jewish early adolescents’ perceptions of their positive youth development, identity development, and purpose. Three theoretical frameworks informed the study, including Lerner’s 5 C’s of positive youth development, Marcia’s identity development, and Damon’s youth purpose. Specifically, the study explored how Jewish early adolescents perceive certain aspects of the local Jewish community as supportive of positive youth development, identity development, and youth purpose. I collected qualitative data through a series of three interviews with 4 Jewish early adolescents recruited using purposeful sampling. Data were analyzed through a hybrid approach to thematic analysis. The first finding was that Jewish …

Learning To Be Human: Ren 仁, Modernity, And The Philosophers Of China's Hundred Days' Reform, Lucien Mathot Monson

USF Tampa Graduate Theses and Dissertations

In a period of deep political division, insurrection, opium addiction, foreign conflicts, and economic distress, three intellectuals, Tan Sitong 譚嗣同 (1865-1898), Kang Youwei 康有爲 (1858-1927), and Liang Qichao 梁啓超 (1873-1929), developed philosophical systems to identify the source of China’s problems and to devise solutions. With these philosophical theories, they enacted a political movement to reform Chinese government and society known as the “Hundred Days’ Reform” (wuxubianfa 戊戌變法) of 1898. While scholars like Chang Hao, Wing Sit-chan, and Joseph R. Levenson have all written on all or some of these reformers, they have done so largely from the perspective of Chinese …

Nietzsche And Eternal Recurrence: Methods, Archives, History, And Genesis, William A. B. Parkhurst

USF Tampa Graduate Theses and Dissertations

I argue that Nietzsche's thought of eternal recurrence is merely a kind of thought experiment that has two forms of engagement. The first form of engagement is destructive and results in the principles of classical logic being reduced to epistemic nihilism. In this first form, Nietzsche is thinking eternal recurrence, as it is presented in previous philosophers, to its end. The second form of engagement does not require the presuppositions of classical logic and is made through the affect of disgust. This second mode of engagement can result in two outcomes; suicidal pessimism or life affirmation.

The work on eternal …

Evaluation Of Structural Equation Modeling (Sem) Fit Indices In Distinguishing Between Circumplex And Other Factor Models, Andrew J. Thurston

USF Tampa Graduate Theses and Dissertations

The circumplex offers a useful paradigm for simultaneously modeling relationships between latent variables and visually representing an individual’s profile. Previous research has demonstrated the Circular Stochastic Process Model (CSPM) can establish the presence of the circumplex in sample data using Confirmatory Factor Analysis (CFA), allowing researchers to test the circumplex with familiar global fit indices such as the Confirmatory Fit Index (CFI), Tucker-Lewis Index (TLI), Root Mean Squared Error of Approximation (RMSEA), and Unbiased Standardized Root Mean Squared Residual (SRMRu). However, it is not yet clear if these fit indices are sensitive to detect circumplexes under a variety of conditions. …

An Automated Framework For Connected Speech Evaluation Of Neurodegenerative Disease: A Case Study In Parkinson's Disease, Sai Bharadwaj Appakaya

USF Tampa Graduate Theses and Dissertations

Neurodegenerative diseases affect millions of people around the world. The progressive degeneration worsens the symptoms, heavily impacting the quality of life of the patients as well as the caregivers. Speech production is one of the physiological processes affected by neurodegenerative diseases like Alzheimer’s disease, amyotrophic lateral sclerosis (ALS) and Parkinson’s disease (PD). Speech is the most basic form of communication, and the effect of neurodegeneration degrades speech production, thereby reducing social interaction and mental well-being. PD is the second most common neurodegenerative disease affecting speech production in 90% of the diagnosed individuals. Speech analysis methods for PD in clinical methods …

Investigation Of Hurricane Irma Deposits, Big Pine Key, Florida, Youzhu Wang

USF Tampa Graduate Theses and Dissertations

Few paleotempestological studies have focused on coastal sinkholes, a common feature in Florida, which can receive and preserve storm overwash sediments. The major goal of this research is to improve our understanding of the characteristic signatures of storm sediments in sinkholes thereby determining reliability of these environments as proxies for hurricanes. Hurricane Irma as a Category 5 storm provides an excellent case study for characterizing storm deposits in sinkholes on Big Pine Key. I cored at four sinkholes along a 350 m transect normal to the shoreline. Core sediments were characterized using physical description, short-lived radioisotope dating, sediment grain size …
