Environmental drivers of Northern bobwhite fall and winter survival and resource selection in Southwest Missouri
(University of Missouri--Columbia, 2020)
Northern bobwhite (Colinus virginianus) populations have declined over the last 50 years throughout the majority of their historical range, primarily due to habitat loss and degradation caused by modern farming practices, increased urbanization...
Formulation development of a novel antivirulence compound for enhanced pharmocokinetic properties
(University of Missouri--Columbia, 2019)
be controlled by the volume of water filled in ultrasonic tank, and there is a threshold below which the particle size can be maintained in a narrow range, e.g. of 320-360 nm when 0.02% w/v Tween 80 is applied. Both the small platelike particles and the large...
Modification of fatty acid composition in soybean seeds to improve soybean oil quality and functionality
(University of Missouri--Columbia, 2011)
The purpose of this project is to modify the fatty acid composition in soybean seeds to improve soybean oil quality and functionality. By sequencing the FAD2-1A and FAD2-1B genes in 24 plant introductions, we identified two novel mutant alleles: one...
From saving face to saving lies : prioritizing the public in public relations
(University of Missouri--Columbia, 2021)
Traditional crisis communication literature emphasizes how organizations can use communication to preserve their image after a negative event. From image restoration theory to the situational crisis communication theory, these frameworks aim...
Human rights in presidential democracies : does a runoff rule reduce repression?
(University of Missouri--Columbia, 2019)
I argue that within a democratic context the presence of a presidential runoff rule leads to the following outcomes: a reduced distance between the ideological position of the president and the median voter, a reduced percent of the cabinet...
Exploring the dynamics of competing risk models for multiple discrete outcomes
(University of Missouri--Columbia, 2010)
discrete outcomes influenced by unobserved heterogeneity components. In the first essay, I analyzed the dynamics of firm's credit rating changes in a correlated competing risk framework. In each period, a firm's credit rating may be upgraded, downgraded...

Reporting serendipity in biomedical research literature : a mixed-methods analysis
(University of Missouri--Columbia, 2018)
As serendipity is an unexpected, anomalous, or inconsistent observation that culminates in a valuable, positive outcome (McCay-Peet & Toms, 2018, pp. 4–6), it can be inferred that effectively supporting serendipity will result in a greater incidence...
