The impact of international institutions on foreign aid delivery tactics
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Do international institutions influence state behavior? Do the events that take place within international organizations affect foreign policy behavior ...
Genetic diversity and distribution of the ringed salamander (ambystoma annulatum) across multiple spatial scales
(University of Missouri--Columbia, 2018)
that correspond to watershed boundaries. Within each cluster, I found evidence for decreased gene flow in recent generations, possibly due to the extensive timber harvest and land conversion of the CIH post European settlement. Over smaller spatial scales, I found...
Genetic and microbiota-mediated phenotype variability in the min mouse model of human colorectal cancer
(University of Missouri--Columbia, 2019)
Complex diseases develop as a result of genetic predisposition and environmental factors that determine individual risk. Environmental factors such as geographical location, diet, and lifestyle choices shape the gut ...
Capturing the complexity: examining the effect of instructional intensity in the context of a response to intervention framework on learning outcomes for students with academic and behavioral needs
(University of Missouri--Columbia, 2022)
representative Early Childhood Longitudinal Study 2011 data set. With a dynamic system framework, teachers' instructional practices were investigated at a micro-level learning environment and the level of school Response-to- Intervention implementation...
Site preparation for longleaf pine restoration on hydric sites : stand development and ground flora responses 15 years after planting
(University of Missouri--Columbia, 2019)
Longleaf pine (Pinus palustris Mill.) restoration is an important land management goal throughout the Southeast. On hydric sites within the Atlantic Coastal Plain, restoration may involve site preparation prior to planting ...

[EMBARGOED UNTIL 5/31/2024] The entrance speed change lane is an uncontrolled terminal between the entrance ramp and freeway, with the primary purpose of creating a merging area for entering vehicles. The exit speed change ...
A new lumped parameter model for coronary blood flow, using nondimensional analysis
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The studies of the coronary circulation hemodynamics are of great importance due to the high mortality and morbidity associated with coronary diseases. ...
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)
Soybean (Glycine max L. Merrill) is one of the most important legume crops grown worldwide. However, without phosphorus (P) fertilization, soybean yields often are limited by phosphorus availability. Phosphorus is an ...
Deep learning for small object detection in images

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] With the rapid development of deep learning in computer vision, especially deep convolutional neural networks (CNNs), significant advances have been ...
Dynamics of democracy aid allocation : from democratic donors to authoritarian regimes
(University of Missouri--Columbia, 2021)
The purpose of this thesis is to analyze democracy aid allocation mechanisms between Western donors and authoritarian regimes in recipient countries. The theoretical mechanism explains how strategic choices of donors and ...
Multivariate analyses of polygenic risk for impulsivity and alcohol use: a study of longitudinal trajectories of binge drinking in emerging adulthood
(University of Missouri--Columbia, 2022)
This dissertation aimed to extend previous genetic and neurobiological studies of the shared etiology of impulsive personality traits (IPTs), alcohol consumption and alcohol use disorder (AUD). The overarching goals were ...
