Centralized Finance And Decentralized Finance, Leili Pour Rostami

Theses and Dissertations

This dissertation explores different facets of financial markets, focusing on the interplay between decentralized finance, traditional banking systems, and private market relationship lending. By examining these diverse areas, we aim to provide a comprehensive understanding of how emerging financial instruments and market behaviors interact with traditional financial systems. Decentralized Finance (DeFi) offers an escape from the challenges of centralized finance (CeFi). The first essay explores whether and how returns on DeFi instruments, particularly cryptocurrencies, manage to evade the traditional “rules” in response to exogenous central bank monetary policy shocks. The findings reveal that crypto abnormal returns decline significantly with shocks, …

Initial Evaluation Of A Peer Supervision Program For Health Service Psychology Doctoral Students, William Bradley

Theses and Dissertations

Clinical supervision has long been utilized as the primary method of clinical training and evaluation for health service psychology doctoral students. Despite the central role that supervision has played and continues to play in the training of psychologists, little scholarly attention has been given to identifying effective methods for fostering competency in providing supervision. The lack of research in this area is concerning, given the accumulating evidence that negative supervision experiences, such as ineffective or inadequate supervision, are reported by a substantial proportion of trainees (21-92% across studies). Moreover, these experiences are associated with important proximal and distal training outcomes, …

Saved By Naloxone: The Path To Sobriety?, Marli Rose-Firillo Fichtner

Theses and Dissertations

Beginning in the early 2000s, lawmakers sought to mitigate harm and reduce mortality rates by enacting various policies and increasing community outreach, such as educating society about the dangers of opioids. These efforts can be divided into two broad categories: Drug use prevention and harm reduction. Research has been conducted on both of these strategies, utilizing retrospective analysis on outcomes including crime and mortality, among others. It is of great interest to understand which policies are most effective. NALs are an example of harm reduction because they reverse overdoses should they occur. Preemptive naloxone distribution reduces the likelihood of fatal …

Improving Drug Repurposing Success: Integrating Large Database Claims Analysis In Drug Discovery, Joseph Magagnoli

Theses and Dissertations

Drug repurposing has emerged as an innovative strategy to identify new therapeutic uses for existing medications. However, with few notable exceptions, repurposing existing drugs has limited overall success, often failing in randomized controlled trials (RCTs) due to inadequate treatment efficacy in new clinical settings. To improve success rates, I propose a framework titled REMIDY: Retrospective and Experimental Methods Integration for Drug DiscoverY. The REMIDY framework incorporates retrospective claims analysis into the drug discovery process. I demonstrate that retrospective analysis can leverage extensive administrative and clinical data to address translational gaps between pre-clinical experimental models and RCTs. For example, pre-clinical experimental …

In particular, sports job seekers foster work passion through their multiple identifications with sport (playing history, …

A Careful Examination Of The Parameters Impacting The Study Of Plant/Bacteria Interactions, Caroline Victoria Royals

Theses and Dissertations

Our laboratory has been studying how different Caulobacter strains impact Arabidopsis plant growth. While reading papers published by other laboratories, I noticed inconsistencies in the methods used by different plant/bacteria interaction studies. For example, a variety of different variables have been used for defining a bacterium as Plant Growth Promoting (PGP). To establish a baseline, I conducted longitudinal studies that examined the impact of bacteria on all phases of a plant’s life. I found that individual Caulobacter wild type strains impact different aspects of plant growth. In addition, I continuously encountered problems with within and between pot variation in plant …

Machine Learning Approaches To The Exploration Of Ammonia Synthesis Catalysts Utilizing Experimental Data, Rasika Jayarathna

Theses and Dissertations

Traditional heterogeneous catalyst discovery process relies upon human expert-guided experiments based on domain knowledge and human intuition supported by catalyst characterization. However, this process is time and resource-consuming and suffers from human bias. Machine learning (ML) models trained on experimental data have the potential to significantly accelerate this discovery process by guiding experiments to optimize the catalyst performance and increase the understanding of the catalysts. Ammonia synthesis catalysts are a class of catalysts widely investigated in the literature, which has generated decades of experimental data. Moreover, ammonia has been gaining attention since it can be used as a carbon-free next-generation …

Quantifying Extreme Events: Applications Of Probabilistic Methods To Quantify Riverine And Coastal Flood Dynamics In South Carolina And Neighboring Coastal Communities, Ryne Phillips

Theses and Dissertations

Extreme flood events have been persistent throughout history and have challenged human populations around the globe. Over time, scientists and engineers have developed tools and technology to support flood risk management. Most, if not all, of these tools rely on some form of the field of stochastic hydrology. Stochastic hydrology is a broad discipline, but the overarching principle is to use statistical and data-driven techniques to develop an understanding of one or more hydrologic variables (e.g., flood flow or peak storm tide). However, the need for large sample sizes of data that offer insight into all possible combinations of outcomes …

Essays In Labor Economics, Inclusion, And Diversity, Saharnaz Babaei Balderlou

Theses and Dissertations

This dissertation presents a comprehensive analysis of various teacher staffing policies and their impact on teacher retention and turnover. It comprises three studies, each addressing a unique aspect of teacher staffing challenges in the United States and in South Carolina. Chapter 2 investigates how different salary structures (frontloading vs. backloading) affect teacher turnover in South Carolina. Using a Difference-in-Differences (DID) approach and data from FY2014 to FY2023, the study finds that frontloading salary schedules do not significantly impact overall teacher turnover, with negligible effects on novice teachers. However, the impact varies with district characteristics: specifically, frontloading may reduce turnover in …

The Expression Of Mantle Seismic Anisotropy In The Global Seismic Wavefield, Jonathan Wolf, Maureen D. Long, Daniel A. Frost, Tarje Nissen-Meyer

Faculty Publications

The dependence of seismic wave speeds on propagation or polarization direction, called seismic anisotropy, is a relatively direct indicator of mantle deformation and flow. Mantle seismic anisotropy is often inferred from measurements of shear-wave splitting. A number of standard techniques to measure shear-wave splitting have been applied globally; for example, *KS splitting is often used to measure upper mantle anisotropy. In order to obtain robust constraints on anisotropic geometry, it is necessary to sample seismic anisotropy from different directions, ideally using different seismic phases with different incidence angles. However, many standard analysis techniques can only be applied for certain epicentral …

Method – Four participants, ages 4-7, completed norm referenced assessments for language and intelligence. Results – Descriptive results suggest no discernable trends between performance on language assessments and nonverbal IQ measures. The results demonstrated a discernable negative trend between performance on nonverbal IQ measures and linguistic complexity of instructions. Implications – While the …

Calibration And Use Of The Transparency Tube As An Estimate Of Turbidity: An Analysis Of Factors Controlling Light Attenuation In Estuarine Waters, Makenna Leigh Thompson

Theses and Dissertations

The transparency tube is low-cost, portable, and easy to use to measure the transparency or clarity of the water. Filling the tube with water creates a small-scale water column where water will be slowly drained out of the bottom until the Secchi disk at the bottom of the tube is visible from the top opening, and the depth of the remaining water in the tube is recorded in centimeters. Unlike traditional Secchi disk measurements, the advantage of this instrument is that sampling depth in highly turbid waters is possible with a centimeter scale resolution. Transparency tube measurement, through careful calibrations, …

Preregistration And Registration As A New Method For Transparency Of External Validation In Artificial Intelligence And Machine Learning Applications To Address Overfitting, Underspecification, And Shortcut Learning, Marilyn Elaine Gartley

Theses and Dissertations

Statistics has been defined as the study of how information should be employed to reflect on and give guidance for action in a practical situation involving uncertainty. The essence of uncertainty is that there is more than one possible outcome, and the actual outcome is unknown in advance; it is indeterminate. The goal of statistical methods is inference: namely, statistical inference—reaching conclusions about populations or deriving scientific insights from data which are collected from a representative sample of that population through providing a mathematical understanding of inference, quantifying the degree of support that data offer for assertions of knowledge, as …

Faculty Publications

Understanding the drivers of improvements in child undernutrition at only the national level can mask subnational differences. This paper aimed to understand the contributions of factors in the enabling environment to observed differences in stunting reduction between districts in Rwanda. In 2017, we conducted 58 semi-structured interviews with mid-level actors (n = 38) and frontline workers (n = 20) implementing Rwanda's multi-sectoral nutrition policy in five districts in which stunting decreased (reduced districts) and five where it increased or stagnated (non-reduced districts) based on Rwanda's 2010 and 2014/15 Demographic and Health Surveys. Mid-level actors are government officials and service providers …

Functional Multivariable Logistic Regression With An Application To Hiv Viral Suppression Prediction, Siyuan Guo, Jiajia Zhang Ph.D., Yichao Wu, Alexander C. Mclain Ph.D., James W. Hardin, Bankole Olatosi Ph.D., Xiaoming Li Ph.D.

Faculty Publications

Motivated by improving the prediction of the human immunodeficiency virus (HIV) suppression status using electronic health records (EHR) data, we propose a functional multivariable logistic regression model, which accounts for the longitudinal binary process and continuous process simultaneously. Specifically, the longitudinal measurements for either binary or continuous variables are modeled by functional principal components analysis, and their corresponding functional principal component scores are used to build a logistic regression model for prediction. The longitudinal binary data are linked to underlying Gaussian processes. The estimation is done using penalized spline for the longitudinal continuous and binary data. Group-lasso is used to …

Differential Regulation Of Stard1, Stard4 And Stard6 In The Human Ovary, Nawal A. Yahya, Steven R. King, Bo Shi, Aisha Shaaban, Nicole E. Whitfield, Chunmei Yan, Richard J. Kordus, Gail F. Whitman-Elia, Holly A. Lavoie

Cell Biology and Anatomy Faculty Publications

Cells actively engaged in de novo steroidogenesis rely on an expansive intracellular network to efficiently transport cholesterol. The final link in the transport chain is STARD1, which transfers cholesterol to the enzyme complex that initiates steroidogenesis. However, the regulation of ovarian STARD1 is not fully characterized and even less is known for upstream cytosolic cholesterol transporters STARD4 and STARD6. Here, we identified both STARD4 and STARD6 mRNAs in the human ovary but only detected STARD4 protein since the primary STARD6 transcript turned out to be a splice variant. Corpora lutea contained the highest levels of STARD4 and STARD1  mRNA and …
