(University of Missouri--Columbia, 2020)
Northern bobwhite (Colinus virginianus) have experienced widespread, long-term population declines. Bobwhite populations in Missouri have declined 2.7% annually between 1966 and 2015, and 3.5% annually between 2005 and 2015, for a cumulative loss...
Toward a common market in residency: international migration and regional integration
(University of Missouri--Columbia, 2005)
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 ...
Coprolites of the late eocene using virtual paleontology from the Pipestone Springs Main Pocket, Montana
(University of Missouri--Columbia, 2022)
volumes and diameters for statistical comparison between the two different size classes of coprolite. In combination with volume renders of the segmented material, we also adopt more traditional methods such as thin-section petrography and scanning...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation studies China's housing market and macroeconomic activity with a strong focus on the role of monetary policy behind the markets. The first two chapters...
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...
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...
