The Geographies of Non-Lethal Weapons: Transformative Technologies and Political Violence
(University of Kansas, 2019-12-31)Non-lethal weapons, like police batons, rubber bullets and tear gas, are increasingly deployed in interventions against a rising number of bodies in contested spaces. They are formed through notions of (in)security and an ... -
The Role of Tidal Interactions and Mergers on the Evolution of Intermediate Redshift Galaxies
(University of Kansas, 2019-12-31)In this work, we present our analysis attempting to constrain the prevalence of tidal interaction and merger (TIM) events on the evolution of intermediate redshift galaxies. The main focus of this work is the effect of ... -
A General Stochastic Volatility Model on VIX Options
(University of Kansas, 2019-12-31)Abstract In this dissertation, we study a general stochastic volatility model for the VIX options (Chicago Board Options Exchange) volatility index, which is a stochastic differential equation with 8 unknown parameters. ... -
Evolution of Sexual Signals in the Drosophila saltans Species Group
(University of Kansas, 2019-12-31)The complex courtship signaling of three of the four species groups of the Sophophora subgenus (e.g., melanogaster, obscura, and willistoni) has been studied. In this dissertation, I examined the complex courtship signaling ... -
Experimental and Theoretical Study of Resonance Raman Spectroscopy in Ground and Excited Electronic States
(University of Kansas, 2019-12-31)Spectroscopy is a powerful tool for the identification, study, and selective control of molecular processes. Raman scattering is particularly useful in observing the vibrational properties of molecules, and identifying ... -
A Meta-Analysis of Psychosocial Interventions for Siblings of Youth with Chronic Medical Conditions
(University of Kansas, 2019-12-31)Siblings of youth with chronic medical conditions may be at risk for psychological adjustment concerns, and interventions targeting the psychosocial needs of siblings are important to address. The purpose of the current ... -
Controlling Interface for Metal-Insulator-Metal Architectures with Ultrathin Dielectric Fabricated Using Atomic Layer Deposition and Sputtering
(University of Kansas, 2019-12-31)The miniaturization of future microelectronics demands the development of high quality ultrathin (few to sub-nm) dielectric films for application in metal-insulator-metal (MIM) architectures. Among all other approaches ... -
Characterizing Petrophysical Properties of Carbonate Rocks Using Nuclear Magnetic Resonance and Complex Conductivity
(University of Kansas, 2019-12-31)Carbonate rocks are well known for their highly complex petrophysical behaviors due to their intrinsically heterogeneous pore geometry and wide range of pore sizes. As a result, both effective characterization of carbonate ... -
Tracking hydrologic response of tile outlet terraces in agricultural systems to storm events
(University of Kansas, 2019-12-31)Title outlet terrace (TOT) systems have been employed for the last century as a best management practice (BMP) to control surface runoff and associated erosion in agricultural fields. By altering the topography (artificial ... -
