Assessing the Sense of Self
(2020-11-23)Can there be a science of the sense of self? If science is the objective study of general principles, beyond the particularities of individuals, can the subjective sense of self ever be described, measured, and modeled in ... -
Assessing the Skill of Six CMIP6 Climate Models in Predicting Arctic Sea Ice to Narrow the Uncertainty in Projections of the September Ice-Free Arctic
(2022-03-08)Arctic sea ice is an important indicator and regulator of the state of the global climate. As global temperatures rise due to climate change, Arctic sea ice is undergoing unprecedented rapid melting, bringing vast physical ... -
Assessing Value and Optimizing Decision-Making in Post-Acute Care Across Diverse Populations
(2024-01-29)My dissertation investigates the enhancement of value in post-acute care (PAC) within the U.S. healthcare system, focusing on the largest source of geographic variation in Medicare costs. It combines individual preferences, ... -
Asset Managers and Financial Instability: Evidence of Run Behavior and Run Incentives in Corporate Bond Funds
(2015-06-26)Asset managers may be a source of systemic risk due to their risk-taking strategies and vulnerability to dramatic outflows. Investor withdrawals trigger asset sales and redemption costs that only impact remaining investors ... -
Assistive Exoskeleton for Injury Prevention During Downhill Walking
(2015-04-08)This thesis presents a device designed to reduce muscular effort during downhill walking. The designed solution is a soft wearable exoskeleton consisting of an air spring, a wearable soft fabric interface that attaches the ... -
Associations Among Exposure to Adversity, Stress Reactivity, Cognitive Self-Regulatory Functioning, and Depression Symptoms in Middle School Youths
(2018-08-17)Identifying and understanding the pathways of risk and maintenance for child and adolescent (youth) depression has been a significant focus in the field of clinical psychological science. Although extensive research has ... -
Astrocytes promote pediatric glioma progression and enhance ex vivo tumor modeling
(2022-09-08)Astrocytes constitute approximately 10-20% of all cells in the human brain and are generally tasked with maintaining tissue homeostasis. These cells support neuronal metabolism and ion transport, regulate the extracellular ... -
Asymmetric Catalysis of Ionic 1,2-Rearrangements
(2022-03-17)In Chapter 1, we report the development and study of an aryl-iodide-catalyzed Wagner–Meerwein rearrangement reaction. This process converts styrenes bearing cumyl, t-butyl, and i-propyl substitution into enantioenriched ... -
Asymptotic Symmetries in Four-Dimensional Gauge and Gravity Theories
(2017-05-11)Recent developments have uncovered a deep relationship between soft theorems in quantum field theories and asymptotic symmetries. We investigate five explicit examples wherein these connections are studied and verified. ... -
At the Heart of the Genome: Rare Genetic Variation, Cardiovascular Disease, and Therapy
(2014-06-06)Studies of large families with inherited single gene disorders identified a role of rare genetic variation as a cause of disease and enabled gene-based diagnosis. The increasing availability of population-scale genomic ... -
At the Origins of Welfare Policy: Law and the Economy in the Pre-Modern Mediterranean (1150-1350)
(2014-10-21)This dissertation is an economic and institutional history of the first comprehensive public health and welfare system in the Western world. Based on previously unexamined archival and archaeological evidence from several ... -
Athlete Rankings: An Analysis of Elite Women's Cyclists
(2023-06-30)Women’s professional sports are on the rise, and with that comes an increased interest in athlete statistics and predictive analytics. Many mainstream approaches used to rank athletes today involve an analysis of naturally ... -
Atmospheric characterization of high-gravity hot Jupiters with ACCESS
(2022-05-12)The previous month marked the 5,000th confirmed exoplanet discovery, a milestone in the next era of exoplanet science, exoplanet characterization. To that end, several recent ground and space-based surveys have begun ... -
Atmospheric Observations and Models of Greenhouse Gas Emissions in Urban Environments
(2015-05-18)Greenhouse gas emission magnitudes, trends, and source contributions are highly uncertain, particularly at sub-national scales. As the world becomes increasingly urbanized, one potential strategy for reducing these ... -
Atmospheric Pressure Chemical Vapor Deposition of Fluorine-Doped Tin Oxide and Tin-Germanium Oxide: Photovoltaic and Energy Storage Applications
