differentials. I used a logit model to estimate whether or not Missouri cities will participate or not in the 2004 sales tax holiday. I found that cities consider their own characteristics and their neighbor's characteristics when making the decision...
Digestible amino acid requirements for young female turkeys
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nine experiments were conducted to determine the optimal digestible isoleucine (dIle), valine (dVal), leucine (dLeu), phenylalanine plus tyrosine (dPT) requirement of female...
An ecological study of American Ginseng (Panax quinquefolius L.) in the Missouri Ozark Highlands: effects of herbivory and harvest, ecological characterization and wild simulated cultivation
(University of Missouri--Columbia, 2006)
Matrix population analysis was used to analyze eight years of demographic data from six American ginseng (Panax quinquefolius L.) populations in east-central Missouri to examine effects of herbivory by white-tailed deer (Odocoileus virginianus Zimm...
Welfare and Work in the 1990s: Experiences in Six Cities
(Department of Economics, 2004)
Our study examines the dynamic structure of welfare participation and the labor market involvement of recipients starting in the early 1990s and extending through 1999 in the core counties containing six major urban areas: Atlanta, Baltimore...
Transaction costs and market thinness in crop byproduct markets
(University of Missouri--Columbia, 2017)
Studies in crop byproduct literature have looked more at the nutrient impacts, rather than analytical cost implications of crop byproducts in livestock feed rations. Thin market studies stated the lack of product volume ...
Regeneration of soil microbial, physical, and chemical properties in restored bottomland hardwood forest wetlands
(University of Missouri--Columbia, 2023)
(WRP)] was initiated with the goal of reducing the loss of wetlands and restoring wetlands previously converted to agricultural land use. Despite the importance of preserving and restoring wetlands, the benefits of wetland restoration have not been well...
Studies on the physical properties and preservation of the North American pawpaw (Asimina triloba) fruit
(University of Missouri--Columbia, 2023)
regions of the world. The fruit is native to the United States and grows in over 30 states in the United States including Missouri, Indiana, Ohio, Illinois, and parts of Texas. The fruit has remained underutilized and uncommercialized for several centuries...
Three essays on applied economics and finance
(University of Missouri--Columbia, 2023)
This dissertation empirically analyzes the financial decision-making of private and public corporations. It comprises four main chapters. The second and third chapters examine how private agents respond to fiscal policies ...
Identification and management of glyphosate-resistant annual bluegrass (Poa annua L.)
(University of Missouri--Columbia, 2010)
bluegrass (hereafter referred to as CCMO1) in Columbia, Missouri survived an application of glyphosate following more than 10 years of continuous applications. Research was conducted in vitro to identify the extent of glyphosate-resistance in CCMO1...
Evaluation of Cement-Based Reactive Media for Contaminant Remediation
(University of Missouri -- Kansas City, 2018)
Water contaminated with heavy metals, arsenic, and other industrial pollutants
poses a severe risk to human health. Reactive media present an opportunity to intercept
contaminants but have high material or environmental ...
Uncovering the genetic architecture and metabolic basis of amino acid composition in maize kernels using multi-omics integration
(University of Missouri--Columbia, 2020)
composition display extensive natural variation which can be utilized to uncover the genetic basis and identify new targets for seed amino acids biofortification. Hence to uncover the genetic architecture of amino acids composition in maize kernels we used...
Fluctuating asymmetry as a measure of developmental instability in Arikara bioarchaeological assemblages
(University of Missouri--Columbia, 2018)
from skeletal assemblages excavated from numerous Arikara archaeological sites along the Missouri River in South Dakota. These assemblages were selected for this study because they represent a single, culturally and genetically affiliated population...
Phytoplankton response to water quality threats in Midwest reservoirs
(University of Missouri--Columbia, 2021)
Harmful cyanobacterial blooms and invasive species threaten water quality. These threats are expected to worsen in the future, emphasizing the need for creative management solutions and a thorough understanding of their ...
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)
With the increasing adoption of transgenic maize with resistance to rootworms, combined with glyphosate tolerance, as a control tactic for western corn rootworm, Diabrotica virgifera virgifera LeConte, an understanding of ...
Transcriptional profiling by deep sequencing indentifies [sic] differences in mRNA transcript abundance in in vivo derived vs. in vitro cultured porcine blastocyst stage embryos
(University of Missouri--Columbia, 2010)
In vitro embryo culture systems promote development at rates lower than in vivo. The goal of this project was to discover transcripts that may be responsible for a decrease of embryo competency in blastocyst stage embryos ...
Tissue inhibitor of metalloproteinase-1 contributes to reduced fecundity in a rat model of endometriosis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Endometriosis affects millions of women worldwide; its symptoms are pain and reduced fecundity. An established rat model was used which endometriosis is surgically induced (Endo...
Woody species and forest structure in northern Missouri riparian forests with different ages and watershed sites
(University of Missouri--Columbia, 2006)
A chronosequence (1 to 250+ years) of 160 woody species plots was established throughout northern Missouri riparian forests to explain the influence of site hydrology and stand age on species distribution and forest structure. Stand age was found...
Ablation of conceptus PTGS2 provides a new understanding of early pregnancy events in the pig
