(University of Missouri--Columbia, 2022)
), and cauchit links. In a series of simulations studies, I demonstrated that these parametrically parsimonious alternate-link IRT models are comparable to traditional IRT models with regard to (1) data distribution shape, (b) inflection point shift, (c...
Three essays on economics of higher education
(University of Missouri--Columbia, 2019)
split total non-resident enrollment into (a) out-of-state domestic enrollment and (b) foreign enrollment. Specifically, the results reveal no adverse effects of out-of-state domestic enrollment growth on in-state students for any outcome measure. However...
Coupling, membrane conductance, and ion channel mRNA profiles in the establishment and maintenance of network activity in the crustacean cardiac ganglion
(University of Missouri--Columbia, 2021)
cells together, and identify cells based on gene expression alone. We use single cell RNA-seq and single cell qRT-PCR to measure all contigs or a select set of ion channel, receptor, and gap junction mRNAs. We find these methods do not reproduce...
Three essays on the economics of pesticide use
(University of Missouri--Columbia, 2022)
of 343 Missourians. Results show positive preferences for tomatoes produced using 50 percent less pesticides as usual, but the willingness-to-pay for these tomatoes is only 6 percent above conventional tomatoes compared to 28 percent for organic produce...
Docosahexaenoic acid and lipid peroxidation products : insights from studies with microglial cells and mouse brain
(University of Missouri--Columbia, 2019)
microglial cells, we first tested the effects of docosahexaenoic acid (DHA) and its peroxidation products on LPS-stimulated inflammatory responses involving the NF-_B pathway, as well as its ability to upregulate the Nrf2/ARE/HO-1 antioxidant response pathway...
Load and resistance factor design of drilled shafts subjected to lateral loading at service limit state
(University of Missouri--Columbia, 2018)
Since 2007, the American Association of State Highway Administration Officials (AASHTO) has made utilization of Load and Resistance Factor Design (LRFD) mandatory on all federally-funded new bridge projects (AASHTO, 2007). ...
The politics of CO2 emissions
