Three essays on the competitiveness of the US corn seed industry
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation provides an analysis of various aspects of the competitivity of the US corn seed industry. In the first essay I develop a price depend model of seed demand...
Use of main channel and shallow-water habitat by larval fishes in the lower Missouri River
(University of Missouri--Columbia, 2006)
I developed a series of research objectives organized in a spatial hierarchy to characterize larval fish nursery habitat within the lower Missouri River. Native carpsucker spp./buffalo spp. (Carpiodes spp./Ictiobus spp.) and chub spp. (Macrhybopsis...
Using conflict positioning as a pretreatment in the public's evaluation of crisis management
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] By conducting a controlled experimental design, this study examined the effectiveness of conflict positioning, which was defined by Cameron (2004) as positioning an organization...
Decadal mass balance of the Antarctic ice sheet from satellite radar altimetry and its contribution to global sea level change
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this research, we estimated the decadal mass balance of the Antarctic ice sheet using the European Space Agency's ERS-1 and ERS-2 satellite radar altimeter data over the time...
Classification of rock glaciers in southern Colorado based on ice content using radar interferometry and thermal remote sensing
(University of Missouri--Columbia, 2020)
Remote sensing provides a means of assessing potential water resources stored in alpine ground ice; this study focuses on rock glaciers, in particular. A rock glacier is a landform composed of block of loose debris (talus) ...
Capturing the strategic pivot: Identifying the performance outcomes of new venture pivots
(2020)
to the methodological challenges that arise when approaching the subject, which include the difficulty of identifying when a pivot has taken place (in real-time, and for a sufficiently large number of ventures that researchers can have confidence in their results...
Essays on labor economics
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation consists of two chapters on labor economics. In the first chapter, we study redistributions via the United States Social Security retirement system for cohorts...
Structural geology, tectonic geomorphology, and neotectonics of the central Afar Rift, Ethiopia and Djibouti
(University of Missouri--Columbia, 2018)
The central Afar depression offers an opportunity for quantitative analysis of the final stages of continental breakup at a divergent triple junction. Here, Quaternary faulting dissects Plio-Pleistocene flood basalts, ...
Effect of plagioclase crystallization on liquid and magma viscosity in the Anorthite-diopside-dorsterite-quartz system
(University of Missouri--Columbia, 2006)
SiO2 (CMAS) glasses were synthesized as analogs for dacitic and basaltic lavas. Liquid viscosities were measured between 101 and 1013 Pa s, over the temperature range of approximately 1600 to 700⁰C, using concentric cylinder ...
Experimentally assessing the influence of resource availability and social aggregation on the parasites of raccoons
(University of Missouri--Columbia, 2009)
I investigated how experimental increases in social aggregation and resource availability affected ectoparasite prevalence and intensity (number of parasites on infested hosts only) and endoparasite species richness of raccoons. Twelve independent...
Effects of red wine and grape juice against foodborne pathogens and probiotics
(University of Missouri--Columbia, 2008)
survived exposure to up to 80% of each red wine, even though the decrease in numbers was significant from the initial 107 CFU/mL. The pathogens were inhibited by up to 50-60% red grape juice. This indicates that the alcohol present in wines is not the only...
Factors influencing Chinese electronics engineers' selection of information sources
(University of Missouri--Columbia, 2008)
journals are among the top information sources engineers use. A number of factors, e.g., accessibility, ease of use and quality, have been found to be potential factors influencing engineers' information source use patterns. However, previous studies...

Child maltreatment results in over 3 million referrals annually to U. S. child
protective services agencies and an estimated 695,000 children who are determined
to be child maltreatment victims. There are ongoing concerns ...
Assessment of Statistical Methods Applied to Geochemical Data for Paleoenvironmental Interpretation: A Case Study from the Al-Azraq Basin, Jordan
(2021)
This study investigates the appropriateness of statistical methods frequently applied to inorganic geochemistry data for indicating past environments. The data examined are two large geochemical data sets of cored lacustrine ...
Reverse knowledge absorptive capacity of MNE-HQ (RKAC): conceptualization, theoretical framework, and empirical testing
(University of Missouri--Columbia, 2021)
Despite the increasing importance of reverse knowledge for innovation and competitive advantage of multinational enterprises (MNEs), the issue of how to make reverse knowledge transfer (RKT) more effective is under-explored. ...
The survival and growth of shortleaf pine systems in the Missouri Ozarks : effects of competition, genetics, and site preparation
(University of Missouri--Columbia, 2019)
survival and growth rates of planted shortleaf pine relative to artificial and natural hardwoods, identify barriers to regeneration success, and develop tools for individual tree assessment. Data from three long-term studies in southeastern Missouri were...
Economic analysis of woody biomass harvesting in the Missouri Ozarks
(University of Missouri--Columbia, 2010)
An integrated mechanized timber harvest thinning treatment to remove small diameter trees and merchantable saw logs was conducted on 30 acres of the Missouri, Ozarks in the summer of 2009. Two silvicultural treatments (single tree selection...
