A Critical Analysis Of Discrepancies In Behavioral Health Program Ratings By Evidence-Based Practice Registers For Behavioral Health, Miranda Jade Lee-Easton

Dissertations

Decision makers in the behavioral health disciplines are under increasing pressure to identify and implement evidence-based practices (EBPs). These decision makers often do not have the time or expertise to assess primary studies of program efficacy or effectiveness. They could benefit from tools to assist them in identifying and implementing EBPs. One tool is an evidence-based practice register (EBPR). Prior studies have documented that when multiple EBPRs rate a given program, they may come to seemingly conflicting program ratings. The prior research concerning the reason for these conflicts is sparse. The purpose of the present study is to understand how …

High-Dimensional Variable Selection Via Knockoffs Using Gradient Boosting, Amr Essam Mohamed

Dissertations

As data continue to grow rapidly in size and complexity, efficient and effective statistical methods are needed to detect the important variables/features. Variable selection is one of the most crucial problems in statistical applications. This problem arises when one wants to model the relationship between the response and the predictors. The goal is to reduce the number of variables to a minimal set of explanatory variables that are truly associated with the response of interest to improve the model accuracy. Effectively choosing the true influential variables and controlling the False Discovery Rate (FDR) without sacrificing power has been a challenge …

Socially Aware Natural Language Processing With Commonsense Reasoning And Fairness In Intelligent Systems, Sirwe Saeedi

Dissertations

Although Artificial Intelligence (AI) promises to deliver ever more user-friendly consumer applications, recent mishaps involving fake information and biased treatment serve as vivid reminders of the pitfalls of AI. AI can harbor latent biases and flaws that can cause harm in diverse and unexpected ways. It is crucial to understand the reasons for, mechanisms behind, and circumstances under which AI can fail. For instance, a lack of commonsense reasoning can lead to biased or unfair decisions made by Machine Learning (ML) systems. For example, if an ML system is trained on data that is biased or unrepresentative of the real …

Anti-Woman Invective On The Early Modern Stage: Abuse, Degradation, And Resistance, Savannah Xaver

Dissertations

On the early modern stage, gendered epithets like “strumpet,” “mermaid,” “minx,” “hobby horse,” “courtesan,” “drab,” and “whore” are not just markers of misogyny. Instead, these insults harm the male user as well as their female target. My cross-playwright and cross-genre connections show the complex, wide use and impact of anti-woman terms. A wide-ranging study of the plays of Shakespeare and his contemporaries reveals that gendered insults signify masculine mental decline in tragedies as well as comedies and tragicomedies. In tragedy, the increasingly violent language of male slur users – like, for example, the frustrated Othello, who declares, of his wife, …

Three Essays On Financial Economics, Megersa Daksa

Dissertations

This study presents three essays on financial economics. In the first essay, we examine how monetary policy shocks affect risk aversion and uncertainty, as well as how risk aversion and uncertainty spread across financial markets. Although a recent study shows that monetary policy influences risk aversion and uncertainty in global stock markets, there are no studies on risk aversion and uncertainty spillover across stock, currency, and commodity markets. Following the method of Bekaert et al. (2013), we decompose the implied volatility indexes (VIX's) for the SP500, U.S. exchange rate, gold and crude oil into risk aversion and uncertainty. The decomposition …

Instance Segmentation-Based Depth Completion Using Sensor Fusion And Adaptive Clustering For Autonomous Vehicle Perception, Mohammad Z. El-Yabroudi

Dissertations

Depth sensing is critical for safe and accurate maneuvering in robotics and self-driving car (SDC) applications. Most recent LiDAR sensors, such as Ouster and Velodyne, offer 360 degrees of scanning at the rate of ten frames per second, making them very appropriate for autonomous driving applications. However, LiDAR point cloud data show many shortcomings, especially its data sparsity and unassigned nature, making it very challenging to utilize in applications such as perception, 3D object detection, 3D scene reconstruction, and simultaneous localization and mapping.

In this study, a novel framework using instance image segmentation and the raw LiDAR data for the …

Self-Regulation In The Learning Experiences Of School Choice Students, Melody Lynn Schmidt

Dissertations

This study explores self-regulation in the learning experiences of school choice students who have attended a traditional public school and a charter public school. Research shows self-regulation is a form of non-cognitive executive functioning characterized by many observable traits children employ in their learning environments. Self-regulation development in the learning investments students make relates to school mobility, social identity, and connectedness while navigating their learning amid school changes (Golden, 2017; Langenkamp, 2016). School mobility may impact students by lowering self-regulation and increasing school dropout through compromised social identity and connectedness (Jdaitawi, 2015; Rumberger & Larson, 1998). Understanding the distinction between …

Heterogeneity Estimators In Random-Effects Meta-Analysis In Education, Qian Wang

Dissertations

Over the last four decades, meta-analysis has proven to be a vital analysis strategy in educational research for synthesizing research findings from different studies. When synthesizing studies in a meta-analysis, it is common to assume that the true underlying effect varies from study to study, as studies will differ in design, participants, interventions, or sample size that can lead to heterogeneity in their underlying effects. The magnitude of this heterogeneity between studies can be quantified as τ2 in a random-effects meta-analysis. Estimating the between-study heterogeneity (τ2) becomes an important part of random effects meta-analysis reporting, since this quantity plays a …

A Framework For Assessing The 4th Rank Dispersivity Tensor Under Anisotropic Axial Symmetries, Xiang Fan

Dissertations

Multi-dimensional expansion of the advection-dispersion equation necessitated the representation of dispersivity as a 4th rank tensor. This tensorial form of dispersivity has 81 terms in three-dimensions with a maximum of 36 independent terms that may be used to describe Fickian spreading of a dissolved contaminant plume according to intrinsic properties of a porous medium. The complexity of the 4th rank tensor has led to the common practice of simplifying the tensor to only 2 or 3 independent terms by assuming isotropic conditions, although isotropic porous media are uncommon in nature as many natural geologic systems exhibit pronounced anisotropy. A broad …

Crafting A Different Kind Of Story: Experiences Of Creative Writers Leading In Higher Education, Meredith L. Dodson

Dissertations

Connections between creativity and leadership often focus on how fostering creativity can help an organization. Despite the value that creativity can bring to organizations, Mueller et al. (2011) found that creative people themselves are not seen as leadership material. Yet many people with creative backgrounds do take on leadership roles, particularly in higher education.

This qualitative study explores the experiences of higher education leaders who have a background in creative writing and how those leaders perceive the interaction of the leadership role with their creative experience. The sample included 12 mid-level leaders in higher education who had an MFA or …

Developing Distributed Real-Time Hybrid Simulation For Dynamic Response Evaluation Of Floating Wind Turbine, Hezha Lutfalla Sadraddin

Dissertations

Floating wind turbine (FWT) has a significant role in producing clean and sustainable energy in unlimited spaces with more steady wind and less cost. The design, construction, and safe operation of FWTs require a deep understanding of their dynamic responses under combined aerodynamic and hydrodynamic loads. Conventional FWT model experiments utilize wave tanks and wind tunnels. However, laboratory size and capacity and the scaling conflicts between the Froude and the Reynold numbers in these coupled wind-wave loading tests impose challenges to replicate dynamic responses of FWT. Alternatively, real-time hybrid simulation (RTHS), which combines numerical simulation and physical experiment of FWT …

Preclinical Behavioral Assessments Of Mitraginyne, The Main Psychoactive Alkaloid In Kratom, Rachel Burroughs

Dissertations

Mitragyna speciosa (kratom) is a medicinal plant indigenous to Southeast Asia and Africa with a long history of use for a variety of ailments, including diarrhea, pain relief, cough suppression, and amelioration of opiate withdrawal symptoms. Despite its status as an herbal remedy, kratom is banned in some countries due to a myriad of negative health risks. Preclinical psychopharmacology studies of mitragynine (MG), the main alkaloid of kratom, indicate it has opioid-like effects at higher doses and psychostimulant-like effects at lower doses. The current study utilized three rodent behavioral paradigms to evaluate the putative psychostimulant effects of MG. The specific …

Time-Dependent Photoionization Modeling Of Warm Absorbers In Active Galactic Nuclei, Dev Raj Sadaula

Dissertations

Warm absorber spectra are bound-bound and bound-free absorption features, seen in the X-ray and UV spectra from many active galactic nuclei (AGN). The widths and centroid energies of these features indicate they occur in outflowing gas moving with hundreds to thousands of km/s. Depending upon the energy and momentum of the outflow, it can affect the gas within the host galaxy. Thus, warm absorbers’ mass and energy budgets are of great interest. Estimates for these properties depend on models that connect the absorption features' observed strengths with the density, composition, and ionization state of the absorbing gas. Such models assume …

Studying The Synthesis Of 196Hg At Astrophysically Relevant Energies Through The Measurement Of Capture Reaction Cross-Sections Of (P, Γ) (P, N) And (P, Α) Reactions, Khushi Bhatt

Dissertations

Understanding the origin of all the chemical elements is an important question for the nuclear-astrophysics community. There are many unanswered questions like: What astrophysical events are responsible for the synthesis of what particular chemical elements? How many different elements were made in total? What is the abundance of each synthesized element? etc. Currently, scientists are largely depending upon theory and simulations to define nuclear and astrophysical reaction. This makes it critical to have accurate experimental nuclear physics data to input in astrophysical theoretical models. However, out of more than 20000 reactions involved in these calculations, only a very few are …

Peridynamic Modeling Of Crack Propagation In Brittle Materials With Electromechanical Coupling, Semsi Coskun

Dissertations

The bond-based peridynamics (BB-PD) is a widely used peridynamic model in the literature. Despite Poisson's ratio restriction, it still serves as a powerful tool to solve challenging engineering problems with a relatively cheap computational cost. Consider the Poisson ratio of the material does not deviate from the ones that BB-PD can model. In that case, it becomes advantageous to use the BB-PD compared to other PD models in terms of computational cost and simplicity. However, the BB-PD suffers from the so-called surface or skin effect where the material response at boundaries becomes softer than the bulk material points. As a …
