Essays in Macroeconomics and Entrepreneurship
(2019)This dissertation is comprised of three chapters in macroeconomics, entrepreneurship, and heterogeneous agent models. In the first chapter, I answer two main questions --- What are the empirical facts regarding entrepreneurial ... -
Harnessing the Reactivity of Sulfamate Esters and Sulfamides to Enable Position-Selective C-H Halogenation Processes
(2019)Synthetic technologies that enable transformation of typically inert carbon–hydrogen (C–H) bonds into diverse functional groups have streamlined access to complex molecules. These processes, defined as C–H functionalization ... -
The Modernization of Honor in Eighteenth-Century Political Theory
(2019)In this dissertation, I investigate the efforts in eighteenth-century political theory to modernize the sense of honor. Contrary to the belief that influential thinkers of this century—Jean-Jacques Rousseau, Adam Smith, ... -
Forecasted Afrotropical Forest Responses to Climate Change Diverge from Neotropical Predictions with Consequences for Biodiversity Conservation and Carbon Storage
(2019)Understanding how tropical forests respond to changes in the abiotic environment and human disturbance is critical for preserving biodiversity, mitigating climate change, and maintaining ecosystem services in the coming ... -
Using CRISPR/Cas9 Screens to Define Organizing Principles that Govern Drug Sensitivity in Acute Myeloid Leukemia
(2020)In 2019, the cornerstone of the clinical management of acute myeloid leukemia (AML) is chemotherapy. In fact, for the majority of patients diagnosed with AML, their best chance at achieving complete remission is a regimen ... -
Using Life Course Perspective in Making Health Care Decisions in Later life among older Korean Immigrants
(2019)As life expectancy continues to increase in the coming years, the promotion of quality of life in older adults, especially at the end of their lives, grows in importance. Thus, many studies have begun to focus on end of ... -
Identifying Neural, Genetic, and Behavioral Correlates of the p Factor
(2019)Accumulating mental health research encourages a shift in focus towards transdiagnostic dimensional features that are shared across categorical disorders. In support of this shift, recent studies have identified a general ... -
To Eat or Not to Eat: An Investigation of Meal Skipping on Cognitive Functioning
(2018)Inadequate nutrition has been shown to adversely impact brain development and cognitive functioning (Pollitt, Lewis, Garza, & Shulman, 1983). Unhealthy eating practices are frequently formed in college-aged samples; individuals ... -
Development and Piloting of an Intervention to Reduce Alcohol Use and Improve Family Engagement Among Fathers in Kenya
(2020)Problem drinking accounts for 9.6% of disability-adjusted life years worldwide, and disproportionally affects men with disabling physical, psychological, and behavioral consequences. These can lead to a cascade of negative ... -
The Role of Cognitive Deficits in Vulnerability to Depression and Anxiety: An Individual Differences and Neuroimaging Approach
(2019)Mood and anxiety disorders are heterogenous disorders that display complex symptom presentations. While cognitive deficits have been demonstrated in meta-analyses of currently depressed individuals (Snyder, 2013), a number ... -
Intrinsically Disordered Protein Polymer Libraries as Tools to Understand Protein Hydrophobicity
(2019)Intrinsically disordered protein polymers (IDPPs) are repetitive biopolymers that, when enriched with prolines, glycines, and aliphatic amino acids, have observable lower critical solution temperature (LCST) phase transition ... -
The Potential Role of Memory in the Development and Maintenance of Binge and Loss of Control Eating
(2019)Binge and loss of control (LOC) eating are clinically significant symptoms that constitute syndromes characterized by a repetitive pattern of maladaptive and subjectively uncontrollable binge or loss of control eating. The ... -
Linear Dimension Reduction Approximately Preserving Level-Sets of the 1-Norm
(2019)We choose a family of matrices F : \R^D \to \R^k and a metric \rho on \R^k such that with highprobability, \rho(F (x), F (y)) is a strictly concave increasing function of ||x − y||_1 > 8 \epsilon^2for x, y \in \R^D , up ... -
Definition of a murine CD8+ MHCII-recognizing effector T cell population
(2019)CD4+ and CD8+ T cells are dichotomous lineages in adaptive immunity. While conventionally viewed as distinct fates that are fixed post-thymic development, accumulating evidence indicates that these two populations can exhibit ... -
Enabling Technologies for High-Rate, Free-Space Quantum Communication
(2019)Quantum communication protocols, such as quantum key distribution (QKD), are practically important in the dawning of a new quantum information age where quantum computers can perform efficient prime factorization to render ... -
Repeated Evolution of Asexuality Among Hybrids of A Recently Diverged Subspecies Pair in Boechera
(2019)The impacts of hybridization on speciation and biodiversity can be influenced by the persistence and the reproductive mode of hybrids. Persistent sexual hybrids can facilitate gene flow between parent taxa, which can potentially ... -
ESSAYS ON GLOBAL VALUE CHAINS, POLICIES AND INEQUALITY.

Reading and Writing As/if: US Literary Criticism and Identity
(2019)As/if: US Literary Criticism and Identity turns to early queer and third-wave feminist scholarship to identify a unique strategy and style of literary criticism, which I name as/if criticism. As/if criticism is both born ... -
Holographic Methods for Light Manipulation at Microwave and Terahertz Frequencies
(2019)This dissertation is focused on the application of various holographic techniques to manipulate light across frequencies from low gigahertz to the terahertz. None of the holograms described rely on traditional holographic ... -
Riemannian 3-Manifolds with a Flatness Condition
(2019)The fundamental point-wise invariant of a Riemannian manifold $(M, g)$ is the Riemann curvature tensor. Many special types of Riemannian manifolds can be characterized by conditions on the Riemann curvature tensor and tensor ...
