The Carrot vs. the Stick: A Comparative Analysis of Secondary Sanctions vs. Positive Inducements in Gaining European Support for a U.S.-Led Sanction RegimeAndy Gomez
The United States has a history of imposing its will on other countries via aggressive sanction regimes. In many of those regimes, U.S. policymakers note that support from European partner states is paramount to the regime's success. Over the past 20 years, the U.S. and its European partner state's interests have had relatively aligned, fostering cooperation and implementation of like-minded policies against target states. The end of paralleled interests left policymakers with a conundrum, which...
Machine Learning Classification of Digitally Modulated SignalsJames A. Latshaw
Automatic classification of digitally modulated signals is a challenging problem that has traditionally been approached using signal processing tools such as log-likelihood algorithms for signal classification or cyclostationary signal analysis. These approaches are computationally intensive and cumbersome in general, and in recent years alternative approaches that use machine learning have been presented in the literature for automatic classification of digitally modulated signals. This thesis studies deep learning approaches for classifying digitally modulated signals that use...
Fabrication of NMOS Logic GatesSamantha Hahn

In this thesis, NMOS logic gates were studied in order to open a new field of research into logic gates at Old Dominion University. This work focuses mostly on the designs of the mask patterns and the design of the...
Interpreting Summer in the Parks in the National Capital Area of the National Park ServiceBrendan J. Kane
Washington D.C. has witnessed many watershed events throughout the history of the United States of America. One of these events was the Summer in the Parks (SITP) program organized by the National Park Service (NPS) from 1968-1976. Summer in the Parks was a community-based series of events including concerts, park visits, and exhibitions designed to quell racial tensions and promote park usage. Researchers have begun chronicling SITP, but have yet to explore how the story...
Active Military Student Persistence in Online Courses at California Community CollegesStephanie E. Gernert
The diversity of higher education institutions is changing, and more post-traditional students, including those associated with the military, are engaging in higher education. Almost every post-secondary institution in the United States has military students. In 2020, $11.5 billion was spent on over 875,000 eligible military students. Military students often prefer online courses at community colleges due to flexibility around their military career, open-access, and affordability. Yet, few studies examine active military servicemembers alone and, when...
Design, Synthesis and Characterization of Triazole Based Glycoconjugates and 4,6-Acetal Protected D-Glucosamine Derivatives as Low Molecular Weight GelatorsPooja Sharma
Low molecular weight gelators (LMWGs) are small molecules that can form gels in either organic solvents or water in their pure form or as mixtures. LMWGs self-assemble through noncovalent interactions such as hydrogen bonding, halogen bonding, van der Waals interactions and hydrophobic forces in solvents. They have shown great potential in biomedical industry, catalysis and environmental remediation to name a few. Moreover, the formation of metallogels can be used for detection of various ions as...
Two Essays on the Role of Empathy in Consumer Response to User-Generated ContentMohammadali Koorank Behesht
Empathy is known to be the basis of all human interactions and an essential component of human psychology. Empathy includes a cognitive component (perspective-taking) and an affective component (e.g., emotional contagion). The two essays of my dissertation investigate how each of these components of empathy affect consumer responses to user-generated content. Essay 1: Although both price and online review ratings are important cues in consumers’ product quality judgment, most previous studies have treated price and...

An Instrumental Case Study of Confirmative Evaluation in the Continuous Improvement of Online Remote Leaders’ WorkChad Lawrence McLane
Confirmative evaluation is often noted as an important element of models of Human Performance Technology and Performance Improvement, but there exists confusion around what is and what is not confirmative evaluation. A significant issue limiting the use of confirmative evaluation is the Performance Improvement field’s inability to clearly classify confirmative evaluation in terms of its purpose and scope. Additionally, the performance improvement field lacks sufficient examples of confirmative evaluation in the literature necessary to adequately...

The Development and Application of Open-Source 3D Bioprinted Organoid and Tumoroid Models for Translational SciencesXavier-Lewis Palmer
Previous work from our laboratory has demonstrated the use of an accessible, open- source 3D Bioprinter can be used to produce mammary systems and understand their development. Specifically, these have culminated in projects that have allowed for the reliable in vitro generation of mammary and neuro (ectoderm) organoid and tumoroid structures within patient, foreign, and otherwise synthetic extracellular matrices. However, two problems were presented that required exploration: application of these results to mouse models and...
Reevaluating the Factor Structure of the Family Resilience Assessment Scale for African American College StudentsQuandrea Rachelle Harper
The purpose of this study was to reevaluate the initial validation process of the Family Resilience Assessment Scale (FRAS) and to validate the measure for use with African Americans. Although the FRAS has been previously validated using a sample from the general population in the U.S. and has demonstrated cross-cultural utility, its applicability for use specifically with African Americans is inconclusive, as demonstrated by preliminary research findings. In the current study, data were collected from...
The Association of Objectification and Discrimination with Partner Gender and Disordered Eating Behaviors in Bisexual WomenRachel A. Amerson
Sexual minority women are at increased risk of negative outcomes compared to heterosexual women. Bisexual women report disparities when compared to both heterosexual and lesbian women. The disparities experienced by bisexual women also appear to vary based on the gender of their partner, with those partnered with men reporting more negative health outcomes than those partnered with women. One area in which heterosexual and sexual minority women’s experiences differ is in the experience of objectification...
Investigating the Biorisk of Genetically Engineered Thermosynechococcus Elongatus BP1Cherrelle Leah Barnes
Cyanobacteria, also known as blue-green algae, are an ancient group of microorganisms that use simple materials, such as sunlight, carbon dioxide and water, to produce energy while providing oxygen to the atmosphere by performing photosynthesis. Synthetic biology approaches have been employed with cyanobacteria as a platform to produce a range of products, such as biofuels, by inserting a series of genes into the cyanobacterial genome that will allow the conversion of metabolic intermediates to such...
This novel follows an adventure undertaken by a group of scientists and explorers who undertake a quest in search of knowledge. It is an attempt to explore themes such as loneliness, unfamiliarity, and the boundary (a state of mind, perhaps?) separating reverie and reality, sanity and madness, humanity and animality, and the civilized and savage.
Challenging Predictions of Inflationary Models with CMB DataRichik Bhattacharya, Atanu Debnath, Esha Sajjanhar, Shravani Sardeshpande, Pablo Tenorio Hernández & José Ricardo Torres Heredia
Cosmic inflation offers the best known explanations for many of the observed features of the Universe, such as its flatness. An imprint of the qualities of this mechanism is left in the cosmic microwave background (CMB), which can be instrumental to confirm inflation. Unfortunately, there is a plethora of inflationary models, which are a priori in the same footing. It is conceivable that contrasting the predictions of the various models with the measured values of...
Statistical Genetic Discoveries Using Restricted Maximum Likelihood MethodErika Wu
In statistical genetics, genetic association and genomic prediction become more successful with a highly heritable trait. Identifying highly heritable components of a complex disease can thus advance scientific understanding of the disease and potentially lead to effective prevention and treatments. Using Matlab and existing large-scale genome datasets, we evaluate a restricted maximum likelihood approach to identify highly heritable components of a complex disease as a function of multiple clinical variables.
Role of Structural Hierarchy in Multiscale Material SystemsSiavash Sattar
Multiscale material systems derive their effective mechanical properties through a hierarchical organization of their structural elements and components. The hierarchy of a material is related to its effective properties, material processing, and composition. The hierarchy can be defined as an identifiable structural component with a specific size scale, such as the individual fibers collimated into platelets arranged randomly and producing a complex composite system or the lamellar structure in freeze-casted ceramic with the variation of...
The Influences of Disperser Behavior, Host Availability, and Environmental Conditions on the Distribution of Oak Mistletoe [Phoradendron Leucarpum (RAF.) Reveal & M. C. Johnst.] in Eastern Virginia and North CarolinaNicholas Pearce Flanders
Mistletoes are shrubs that typically parasitize the branches of host trees and rely on avian frugivores for seed dispersal. Because mistletoes are restricted to a narrow range of suitable recruitment sites and avian frugivores are more visible than other guilds of seed dispersers, mistletoe-frugivore systems afford opportunities for assessing the roles of dispersal limitation and local environment in determining plant distribution. These mechanisms have been proposed as determinants of the observed association of oak mistletoe...
