This dissertation examines growth of platinum nanoparticles from vapor deposition on SrTiO3 using a characterization approach that combines imaging techniques and X-ray methods. The primary suite of characterization probes includes atomic force microscopy (AFM), grazing-incidence small-angle X-ray scattering (GISAXS), X-ray fluorescence (XRF), scanning electron microscopy (SEM), and X-ray absorption spectroscopy...
Beginning in the 1960s, U.S. federal law required ongoing and systematic planning as a condition of federal transportation funding. An ad-hoc system for forecasting future travel, which has come to be referred to as the "four-step" procedure, quickly became established as the ubiquitous analytic tool for transportation planning. The four-step...
In a 1980 campaign speech to veterans, Ronald Reagan declared that the United States suffered from a "Vietnam syndrome."

Classifying patients to diagnose and treat disease, ensure access to medical care, adhere to standards of quality, contain costs, and fulfill contractual obligations is critical to the delivery of healthcare. While classification is a fundamental standardizing process in healthcare, as a social process it is the product of negotiations, organizational...
ZnO is a member of the unique class of materials known as transparent conducting oxides (TCOs). TCOs are currently used for many applications including flat panel displays, solar cells, and energy efficient windows. Of particular interest is the possibility of developing materials that have high electron mobilities, such that conductivities...
This dissertation analyzes the role of price advertising in the retail grocery setting, first exploring how consumers use price advertising in their shopping location decisions, and then considering ways in which retailers use price advertising to maximize store traffic and profits, given consumer use of information. Chapter 2 provides a...
The main objective of this research is to enhance our understanding of consumer behavior in retailing. This objective is accomplished through the analysis of retailers' customer database. This research provides methodologies for retailers to process the large amount of readily available customer data and make more effective marketing decisions.
This...
Wood-derived ceramics and composites have been of interest in recent years due to their unique microstructures, which lead to tailorable properties. The porosity and pore size distribution of each wood type is different, which yields variations in properties in the resultant materials. The thermal properties of silicon carbide ceramics and...
