This paper further develops models of regional migration, particularly in continents integrating regionally as it magnifies the importance of immigrant behavior for economists and policy-makers. I outline the history of ...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
Accelerated fill-up of the Arbuckle Group aquifer and links to U.S. midcontinent seismicity
(Blackwell Publishing Ltd, 2019)
newly compiled data set for 49 wells across Kansas that provides a unique perspective on the aquifer's performance over two decades. Statistical analysis of falloff test pressures, static fluid levels, and injection volumes shows that Arbuckle pressures...
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...
Resource selection by black-footed ferrets in relation to the spatial distribution of prairie dogs
(University of Missouri--Columbia, 2007)
Once extinct in the wild, the black-footed ferret (Mustela nigripes) is one of the rarest mammals in North America. Reintroductions of ferrets at 13 sites over 10 years have resulted in only 3 self-sustaining populations. ...
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...
Associations between psychosis risk and emotional distress disorders with cortical surface morphometry
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Neuroimaging studies have consistently found structural cortical abnormalities in schizophrenia, especially in structural hubs. However, it is unclear what...
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. ...
Are structural changes in the agri-food sector causing the instability of parochial ag-producers?
(University of Missouri--Columbia, 2009)
Parochial (Amish and Mennonites) agriculture producers have been known for their stability (historically large numbers) (Kollmorgen, 1943). Though, more recently, the percentage of parochial members who are ag-producers has been steadily declining...
Unelected oversight : the politics of government investigations and problem monitoring

(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...
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to quantify water quality in upland...
