A Mixture or a Compound? Community-Level Antecedents of Firms’ Category-Spanning Strategies.
(2016)
This dissertation examines community-level antecedents of firms’ market diversification and product differentiation strategies using the concept of category spanning. Exploiting novel and extensive data on the restaurant ...
Confirmation Bias: Staged Storytelling in Supreme Court Confirmation Hearings.
(2015)
Many scholars have looked at the dramatic elements of trials. But no scholar has looked at the dramatic elements of Supreme Court Confirmation hearings, even though many hearings in recent years--most notably the hearings ...
Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
Flat Strips, Bowen-Margulis Measures, and Mixing of the Geodesic Flow for Rank One CAT(0) Spaces.
(2015)
Let X be a proper, geodesically complete CAT(0) space under a proper, cocompact, and isometric action; further assume X admits a rank one axis. Using the Patterson-Sullivan measure on the boundary, we construct a generalized ...
Geography, Partisanship, and the Politics of Group Threat.
(2015)
This dissertation project engages three broad themes in the political behavior literature. First, it addresses the question of political geography, and how the physical arrangement of individuals affects their political ...
Development of a Time-Resolved Laser-Induced Fluorescence Technique for Nonperiodic Oscillations
(2016)
Time-resolved measurements of ion dynamics could be key to understanding the physics of instabilities, electron transport, and erosion in Hall thrusters. Traditional measurements of the ion velocity distribution in Hall ...
Yoga Participant's Uses of Yoga and Its Associations to Body Image, Self-esteem, and Quality of Life
(2011-11-29)
Spiritual and physical activities, including yoga, increase body image, self-esteem, and quality of life. Traditionally, yoga is both a spiritual and physical activity. The purpose of this study was to determine if there ...
Bayesian Joint Modeling of Longitudinal Trajectories and Health Outcome: A Broad Evaluation of Mean and Variation Features in Risk Profiles and Model Assessments.
(2014)
This dissertation consists of methodology developments and applications for joint modeling of repeated measurements of health risk factors (i.e., longitudinal trajectories) and health outcome data. In the first chapter, ...
Nanostructured Semiconductors for Thermoelectric Energy Conversion: Synthesis and Transport Properties.
(2013)
Half-Heusler (HH) alloys are among the most popular material systems for high temperature thermoelectric energy conversion. Approaches to increase the thermoelectric figure of merit (ZT) of HH range from (1) chemical ...
Bubble Dynamics and Acoustic Droplet Vaporization in Gas Embolotherapy.
(2014)
Gas embolotherapy is a twist on traditional catheter based embolotherapy approaches. Localized gas bubbles generated are used in place of solid emboli normally used to restrict blood flow. The gas bubbles are formed ...
