Children's Experiences in Child-Centered Play Therapy: An Artwork-Based Phenomenological Investigation

Description: Child-centered play therapy (CCPT) is an empirically endorsed approach for children facing specific clinical concerns and life circumstances alike. The majority of research to date has accrued data about clients from secondary sources, such as adult report and observation. The purpose of this study was to explore children's perceptions of participating in CCPT by implementing a developmentally accessible interview medium, allowing children to share their experiences directly. Ten children betwe… more

Hypoxia-Induced Cardiac Arrest Alters Central Nervous System Concentrations of the GLYT2 Glycine Transporter in Zebrafish (Danio rerio)

Description: Hypoxia as a stressor has physiological implications that have been a focal point for many physiological studies in recent years. In some studies, hypoxia had large effects on the organ tissue degeneration, which ultimately effects multiple ecological processes. These organ tissue studies played a part in the development of new fields like neurocardiology, a specialty that studied the relationship between the brain and the heart. This thesis focuses on how hypoxia-induced cardiac arrest alte… more

Deep Learning Approaches to Radio Map Estimation

Description: Radio map estimation (RME) is the task of predicting radio power at all locations in a two-dimensional area and at all frequencies in a given band. This thesis explores four deep learning approaches to RME: dual path autoencoders, skip connection autoencoders, diffusion, and joint learning with transmitter localization.

Novel Phase-Chance Soft Actuators Controlled via Peltier

Description: Soft actuation methods are a developing field of robotics deemed suitable for physical human-robot interactions due to the adaptability of materials and compliant structures. Thermo-active soft actuators are a subset of these which convert thermal energy to mechanical work in the form of elongation, bending, or twisting to conform to the environment. This study is divided into three major studies that all use actuators with a working principle of phase-change fluid vaporizing for expansion with… more

Implementing the Difference in Differences (Dd) Estimator in Observational Education Studies: Evaluating the Effects of Small, Guided Reading Instruction for English Language Learners

Description: The present study provides an example of implementing the difference in differences (DD) estimator for a two-group, pretest-posttest design with K-12 educational intervention data. The goal is to explore the basis for causal inference via Rubin's potential outcomes framework. The DD method is introduced to educational researchers, as it is seldom implemented in educational research. DD analytic methods' mathematical formulae and assumptions are explored to understand the opportunity and the cha… more

β, β'-π-Extended Porphyrins: Exploration of Functionalization and Aromatic Character

Description: Seventeen new dithiophenyl- and napthodithiophenyl- fused porphyrins were synthesized; from these an additional 7 porphyrin oligomers were also synthesized. Additionally freebase 2,7-dimethoxytriphenylene fused porphyrin was also synthesized from a freebase precursor. Aromatic indices NICS and AICD were used to evaluate these new molecules.

Blockchain for AI: Smarter Contracts to Secure Artificial Intelligence Algorithms

Description: In this dissertation, I investigate the existing smart contract problems that limit cognitive abilities. I use Taylor's serious expansion, polynomial equation, and fraction-based computations to overcome the limitations of calculations in smart contracts. To prove the hypothesis, I use these mathematical models to compute complex operations of naive Bayes, linear regression, decision trees, and neural network algorithms on Ethereum public test networks. The smart contracts achieve 95\% predict… more

The University for Who? Student Narratives of Native Identity, Belonging, and Navigating a Racialized Organization

Description: This qualitative case study aims to understand the ways in which students identifying as Native American, American Indian, and Indigenous navigate attending a university informed by their identities. Through semi-structured interviews with Indigenous students and participant observation with a Native American student organization, this study identified how this demographic of students navigate and conceptualize their identities as Native and Indigenous peoples, the benefits of joining a Native … more

Small Scale Fracture Mechanisms in Alloys with Varying Microstructural Complexity

Description: Small-scale fracture behavior of four model alloy systems were investigated in the order of increasing microstructural complexity, namely: (i) a Ni-based Bulk Metallic Glass (Ni-BMG) with an isotropic amorphous microstructure; (ii) a single-phase high entropy alloy, HfTaTiVZr, with body centered cubic (BCC) microstructure; (iii) a dual-phase high entropy alloy, AlCoCrFeNi2.1, with eutectic FCC (L12) -BCC (B2) microstructure; and (iv) a Medium-Mn steel with hierarchical microstructure. The micro… more

Three Essays on Collective Privacy and Information Security

Description: In Essay 1, we seek to expand the insights on an individual's decision to share group content. Social networking sites (SNS) have become a ubiquitous means of socializing in the digital age. Using a survey, we collected data from 520 respondents with corporate work experience to test our research model. Our analysis highlights the complex interplay between individual and group factors that shape users' risk-benefit analysis of sharing group content on social networking sites. Furthermore, the r… more

Ready for Primetime: The American First Army at St. Mihiel, 1918

Description: The American's battle of St. Mihiel in September 1918 has long been a marginalized battle in an almost forgotten war. In the historiography of American World War I involvement, the battle is relegated to a side-show that was little more than a distraction from the Meuse-Argonne. This stance needs to be re-evaluated as St. Mihiel proved an essential training ground for the US Army. The army rapidly expanded and participated in a major offensive, completed the complicated planning process, undert… more

An Assessment and Intervention Model for Establishing Observational Learning during Tact Trials

Description: Observational learning (OL) allows an individual to acquire novel responses by observing others' behavior and the corresponding consequences. The complexity of skills involved with OL may vary with the learning context. A learner may observe modeled responses to both trained (known) and untrained (unknown) stimuli or they may observe both reinforced (correct) and nonreinforced (incorrect) responses. The purpose of this study was to develop assessment and training procedures for OL component ski… more

Differentiating Cardiac Organoids with Chamber Formations

Description: Considering that both cardiovascular disease (CVD) and congenital heart diseases (CHD) are still the leading cause of morbidity and mortality worldwide, there is a need for a robust and reliable cardiac model. Cardiac organoids are complex, three-dimensional cellular constructs that recapitulate the processes of the human embryonic heart. However, certain vital morphological features within the fetus are not yet replicable with cardiac organoids. Here we report our investigation to generate car… more

The Governor and the Gangster: Dewey, Luciano, Commutation, and Controversy

Description: Thomas E. Dewey and Charles "Lucky" Luciano became household names during a 1936 vice trial in which Dewey successfully prosecuted Luciano, a prominent Mafioso, who received a thirty-to-fifty-year prison sentence. Later, Dewey became the Governor of New York and a perennial Republican presidential candidate while Luciano, still in prison, took part in a joint Navy-Mafia intelligence operation in World War II. In 1946, Governor Dewey commuted Luciano's sentence on the condition that he be depo… more
