An in depth evaluation of internal criteria for determining the number of clusters in a data set
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Clustering procedures partition data sets into groups, minimizing the distance within clusters while maximizing the distance between clusters. Clustering can be a powerful tool...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
question of how pre-existing topography controls lava flow system structure in volume-limited flows (Soldati et al., accepted). I concluded that a steep slope results in a single, stable channel, whereas a gentle slope results in an unstable, braided...
Pluton source varition over two magmatic pulses in the white-inyo range, central-eastern California : implications for paleozoic and mesozoic tectonic reconstructions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation uses compositions of plutons in the White-Inyo Range (WIR) of central-eastern California, which is an important tectonic boundary as it is the easternmost...
Ambulatory assessment of physical pain, emotional distress, and alcohol use
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The available research suggests that many individuals with chronic pain drink alcohol to manage their pain. However, few studies have examined the association of alcohol and pain...
Statistical and simulation methods for evaluating stationary and mobile work zone impacts
(University of Missouri--Columbia, 2018)
when traffic volumes are under 1400 veh/hr/ln, and preferably under 1000 veh/hr/ln, due to the drastic increase in the number of conflicts. In addition, three data driven models were developed to predict traffic speed inside a MWZ: a linear regression...
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
been proposed as indicator taxa as they are reliant on insect food reserves and have recently experienced population declines. Thus, we developed two studies in floodplain wetlands to quantify neonicotinoids in Missouri wetlands and potential effects...
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, ...
Biomineralizers from the proterozoic to today : assessing taxonomy and paleoecology through the lens of taphonomy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The onset of metazoan predation is presumed to have triggered an evolutionary arms race of prey defenses, including the advent of biomineralization. Escalating biological...
The effects of metal contamination on larval white sturgeon in the upper Columbia River
(University of Missouri--Columbia, 2018)
how metals affect larval sturgeon behavior and survival. Of particular concern are reported field observations of large numbers of sturgeon larvae with empty guts at a critical point in their life cycle. By putting all these pieces together, I found...
Chemical compositional analysis of polychrome pottery in the northern Casas Grandes area (a.d. 1200-1450)
(University of Missouri--Columbia, 2018)
The northern area of the Casas Grandes Medio Period (A.D. 1200-1450) was not well known archaeologically. 76 Draw is on the border of the Casas Grandes and Salado (A.D. 1275-1450) regions and the nature of interaction and ...
Sleep stage classification using hydraulic bed sensor
(University of Missouri--Columbia, 2018)
Center (BHC) in Columbia, Missouri. And we were allowed to install our hydraulic bed sensors to their study protocol for consenting patients. The heart rate variability (HRV) features, respiratory rate (RV) features, and linear frequency cepstral...
Three essays on monetary and financial economics
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This three-chapter dissertation focuses on the research topics in Monetary and Financial Economics. The first paper examines the time-varying impact of U.S. monetary policy...
Climate and land use effects on hydrologic processes and water allocation in a primarily rain-fed, agricultural watershed
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] There is a need to raise our understanding of the impact of climate variability and change on hydrologic processes at the watershed scale. This is important, particularly...
Synergy of wide-field infrared survey explorer (WISE) and the Sloan Digital Sky Survey in Stripe 82
(University of Missouri--Columbia, 2018)
In this dissertation, I aim to study the evolution of galaxies over the last 6 Gyr by measuring the growth of the global stellar mass density (GSMD) since z = 0.8. My work combines the datasets from two very large surveys, ...
A transdiagnostic investigation of amygdala-vmPFC resting state functional connectivity and emotional distress in daily lives
(University of Missouri--Columbia, 2018)
Mood disorders, anxiety disorders and borderline personality disorder overlap in symptom criteria, are highly comorbid with one another, and group together in factor models of psychopathology (Kotov et al., 2011). These ...
Establishing Metronidazole as a Novel Biomarker of CYP2A6 Activity
(University of Missouri -- Kansas City, 2018)
CYP2A6 is a polymorphically expressed enzyme with variation associated with
smoking behavior, cessation success, lung cancer risk, and differential drug exposure to
numerous medications including anti-infectious and ...
Clothianidin decomposition in Missouri wetland soils
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Neonicotinoids are a class of pesticides that have been prevalently used in agriculture since the 1990s. Globally, most neonicotinoid application ([about]60%) is delivered via...
Assessing the effects of anticoagulant rodenticides on non-target fish species
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Invasive rat species have negatively affected island ecosystems contributing to the decline and extinction of many endemic species. The eradication of rodents on islands can...
