Flow and heat transfer properties of Mono Craters rhyolites : effects of temperature, water content, and crystallinity
(University of Missouri--Columbia, 2008)
The nature of volcanic processes, including rate of magma ascent, exsolution of volatiles, eruption style, and flow distance, is highly dependent on the viscosity of the associated magma and its ability to transfer heat. ...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
of the many amphibian species for which stage-specific data are lacking. Next, I reared larvae of five species (A. annulatum, A. maculatum, A. opacum, A. talpoideum, and A. texanum) from populations along an ~200 km latitudinal gradient in Missouri, USA...
Occupancy modeling of ruffed grouse in the Black Hills National Forest
(University of Missouri--Columbia, 2009)
Ruffed grouse (Bonasa umbellus) are important game birds and the management indicator species for quaking aspen (Populus tremuloides) in the Black Hills National Forest (BHNF). As a result, a robust monitoring protocol ...
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...
Chemical modifications to produce soy-based polyols
(University of Missouri--Columbia, 2009)
This project comprises several chemical routes to produce soy-based polyols for future use in polyurethane foam applications. Soybean oil was polymerized by heat and catalyst to increase molecular weight, and viscosity for ...
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...
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...
How financial decision-making changes when a marriage ends : evidence from the 1992-2016 health and retirement study
(University of Missouri--Columbia, 2019)
Transitioning from being married to divorced or widowed is difficult, financially as well as emotionally. Individuals who had left money matters to their partners during marriage enter a period of decreased financial control ...
Heterogeneity in body condition, survival, and seasonal origins among lesser snow and Ross's geese
(University of Missouri--Columbia, 2018)
condition among hunter harvested individuals and the general population of midcontinent lesser snow and Ross's geese during the spring Light Goose Conservation Order in 2015 and 2016 across Arkansas, Missouri, Nebraska, and South Dakota. I found a body...
Multi-scale factors influencing detection, site occupancy and resource use by foraging bats in the Ozark Highlands of Missouri
(University of Missouri--Columbia, 2007)
Conservation of bat populations requires understanding the associations between bats and their use of resources. We used maximum likelihood to estimate probability of site occupancy using acoustic data for ten species of ...
Job search self-efficacy of east Asian international graduate students
(University of Missouri--Columbia, 2008)
This study was the first to examine Bandura's Perceived Self-Efficacy Model (1986) in the domain of job search self-efficacy on East Asian international graduate students. It also investigated the moderating effects of two ...
Is accuracy in fertility detection mediated by differences in the mate value of the rater and target?
(University of Missouri--Columbia, 2009)
I propose the existence of a perceptual bias in men toward detecting fertility status in women of similar mate value. To test this hypothesis, 153 male undergraduates (raters) chose which of two photographs of the same ...
Prairie stream ecology : temporal and spatial patterns of macroinvertebrates
(University of Missouri--Columbia, 2018)
due to disturbance events. This research focused on expanding the current knowledge of temporal and spatial variation in the macroinvertebrate communities of Missouri prairie streams. Intra-seasonal variation in the macroinvertebrate community of one...
Motivation for smoking and smoking cessation : a self-determination theory investigation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nicotine dependence is conceptualized as a disorder of motivation. Initial drug use is goal-directed, but with the development of dependence it becomes increasingly routinized...
Entrainment and transport of coarse stream bed material in a fluviokarst watershed, south-central Missouri : a tracer particle study
(University of Missouri--Columbia, 2010)
Plateau of south-central Missouri, and Bear Cave Hollow (BCH), one of TCC's surface drainage streams, bed load entrainment and transport dynamics of mainly siliciclastic material, was evaluated using hydrological measurements and 670 painted tracer...
Major life-changing events and preferred retirement time among older adults : evidence from the 1992 to 2014 health and retirement study

This study evaluated the way life-changing events affect older adults' preferred and actual retirement age using the 1992/1993, 1994/1995, 1996, 1998, 2000, 2002, 2004, 2006, 2008, 2010, 2012, and 2014 surveys of the Health ...
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 ...
Differential effects of negative and positive affect on context processing
(University of Missouri--Columbia, 2007)
