advancement, and success. This dissertation also examined how the intersection of race, gender, and class influenced the educational and career pathways of the nine Black women participants. Using the narrative inquiry method and intersectionality as a...
Assessing costs and environmental impacts of municipal food waste treatment options in Columbia, Missouri : a decision support tool integrating life cycle analysis and robust optimization
(University of Missouri--Columbia, 2021)
Many municipal governments currently have goals in place to align with global efforts and policy to reduce greenhouse gas (GHGs) emissions and take advantage of waste as a resource for renewable energy and nutrients. To meet specified goals...
Quantifying corn emergence using UAV imagery and machine learning
(University of Missouri--Columbia, 2022)
and labor needed. With the advance of unmanned aerial vehicle (UAV)-based imaging technology and advanced image processing techniques powered by machine learning (ML) and deep learning (DL), a more automatic, non-subjective, precise, and accurate field...
Characterization of soybean rooting depth in response to different environmental conditions
(University of Missouri--Columbia, 2020)
challenging, especially under field conditions. Nonetheless, a better understanding of root system form and function is critical to develop strategies to breed for more stress-resilient crops for local production environments. Studies of soybean root systems...
Paternal effects on pre-implantation embryo development in cattle
(University of Missouri--Columbia, 2021)
sires. Next, embryos were produced from HP and LP to determine autophagy levels, and blastocyst cell number. LP sires had a higher rate of autophagy than high performing sires, with no effect of SCR. However, the ratio of trophectoderm to inner cell mass...
Interspecific interactions between olive trees and grapevines in vineyard agroforestry systems in an arid climate region
(University of Missouri--Columbia, 2021)
, increased erosion, and increased pest and disease pressure. Agroforestry is a sustainable land-use system proven to address many of these conservation and production issues, and yet, agroforestry's applications in viticulture have been severely overlooked...
Mobile truck entrepreneurship: motivations and strategies of non-food mobile retail truck entrepreneurs in the United States
(University of Missouri--Columbia, 2022)
This dissertation set out to explore the emerging phenomenon of modern mobile retail trucks opening for business across the United States starting in the early 2010s. Thirty-one participants were interviewed, and the data collected was used to glean...
Essays on inequality and mobility of Korean households' income and consumption
(University of Missouri--Columbia, 2021)
and mobility of income and consumption better than the conventional model that assume iid income shocks. At the chapter 3, we deal with non-classical measurement errors in consumption using a double-differencing correction method. Aguiar and Bils (2015) develop...
Identification and characterization of health-promoting benefits and bioactive molecules in black walnuts (Juglans nigra l.) and waste materials from agroforestry systems
(University of Missouri--Columbia, 2020)
plant species to North America that adapts to grow on a wide range of cultivation conditions is an ideal tree for agroforestry practices. Black walnut agroforestry systems provide landowners the opportunity to develop a solid long-term investment...
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)
multivariate genome-wide association study (GWAS) approaches to improve current models of neurogenetic liability for IPTs using a dual-systems framework (e.g., top-down lack of self-control, and bottom-up sensation seeking and urgency), and (2) apply improved...
Persistence of treatment effects in token economies informed by dimensions of reinforcement
(University of Missouri--Columbia, 2020)
systems. The purpose of this three phase study was to evaluate (a) the effects of the most- and least-preferred dimensions of reinforcement on problem behavior and task completion when embedded into token economy arrangements, (b) if the preferred token...
Forecasting wind speeds at tall tower heights within Missouri
(University of Missouri--Columbia, 2022)
-space portraits and the Largest Lyapunov Exponent (LLE) respectively. The methods confirm the results of the fractal analyses. A simple non-linear prediction algorithm, Empirical Dynamical Modeling (EDM) was then used to forecast the wind speeds using a moving...
Communicating reform: apologies and policy implementation for policing's history
(University of Missouri--Columbia, 2022)
