Use of geographic information systems and remote sensing as automated tool for variable rate irrigation prescriptions
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Economic as well as water shortage pressure on agricultural use of water has placed added emphasis on efficient irrigation management. Center pivot ...
Asymptotically efficient estimators for geometric shape fitting and source localization
(University of Missouri--Columbia, 2013)
Solving the nonlinear estimation problem is known to be a challenging task because of the implicit relationship between the measurement data and the unknown parameters to be estimated. Iterative methods such as the ...
Generalized Littlewood-Richardson coefficients for branching rules of GL(n) and extremal weight crystals
(University of Missouri--Columbia, 2018)
This thesis is devoted to the combinatorial and geometric study of certain multiplicities, which we call generalized Littlewood-Richardson coefficients. These are sums of products of single Littlewood-Richardson coefficients, ...
Decision theory and sampling algorithms for spatial and spatio-temporal point processes
(University of Missouri--Columbia, 2019)
In this work, we first present a flexible hierarchical Bayesian model and develop a comprehensive Bayesian decision theoretic framework for point process theory. Then, we provide a comparative study of the approximate ...
The use of electronic feedback to strengthen teacher intervention beliefs, knowledge, attitudes and intentions
(University of Missouri--Columbia, 2019)
The present study examined the efficacy and usefulness of an electronically delivered feedback intervention on overall teacher perceptions of classroom-based behavior interventions, implementation behavior and intentions. ...
Essays on return predictability and active management
(University of Missouri--Columbia, 2019)
In this dissertation, I consider two topics in return predictability and performance evaluation in active management. In the first essay, I propose a production based asset pricing model with labor inputs. In this model, ...
Pretargeted cancer radioimmunotherapy and radioimaging using antibodies and antibody fragments
(University of Missouri--Columbia, 2018)
Over the last few decades, antibodies have become the mainstay of cancer diagnosis and therapeutics. In traditional radioimmunotherapy (RIT), tumor targeting antibodies are directly conjugated with radioisotopes and depending ...
Developing a model of psychiatric visit non-adherence
(University of Missouri--Columbia, 2010)
Non-adherence to psychiatry visits costs the US mental health care system more than one hundred billion dollars annually. Non-adherent visits undermine improvements to patient care quality, erode patient well-being, and ...
Friends in high places : ecology of mycorrhizal associations in alpine plant communities
(University of Missouri--Columbia, 2010)
Mutualisms are ubiquitous in nature, yet these interactions often vary in strength and persistence. This variation raises the questions of what determines whether mutualisms persist or vanish, and how does variation in the ...
Design and optimization of nanoformulation loaded with HIV microbicides
(2013)
The objective of this dissertation is to design and optimize nanoformulation for microbicides intended for the prevention of HIV/AIDS transmission. In chapters 1 and 2, the aims and the scope of this work are introduced, ...
Identity-motivated elaboration : the role of partisan social identities and elaboration in political persuasion and learning
(University of Missouri--Columbia, 2018)
a partisan lens through which all new political information is processed. The integration of the three psychological theories avails a new perspective on the political persuasion process, one that is more nuanced and extensive than that provided...
Approaches for unveiling the kinetic mechanisms of voltage gated ion channels in neurons
(University of Missouri--Columbia, 2019)
Ionic currents drive cellular function within all living cells to perform highly specific tasks. For excitable cells, such as muscle and neurons, voltage-gated ion channels have finely tuned kinetics that allow the ...
Zinc ion fluxes on the pathway to mammalian sperm fertilization competency
(University of Missouri--Columbia, 2019)
For decades, the role of the divalent ion calcium was the focus of understanding mechanisms leading to sperm fertilization competency and management of semen storage. Little focus has been placed on other divalent ions, ...
Structural inferences for reverse transcribing viruses and drug resistance
(University of Missouri--Columbia, 2019)
, and as we've seen with extensive HIV-1 studies, can be thrown into disarray through targeted drug design. The implications of this work stand to benefit the study of plant pararetroviruses and could greatly inform the study of HBV RT, which to this day has...
The Effects of the Classroom Schedule and Teacher Beliefs on Head Start Teacher-Child Interactions
(2013)
Time can be examined from several viewpoints in the early childhood classroom: wasted wait time; instruction which is undifferentiated or not on the child’s cognitivelevel, missing the child’s target learning needs; the ...
Motivation for enrolling in school-based agricultural education expressed by CAFNR freshmen students
(University of Missouri--Columbia, 2010)
The purpose of this study was two-fold: 1) to describe the motivational factors of current CAFNR freshmen student who enrolled in school-based agricultural education, and 2) compare the motivational factors to selected ...
Hierarchical nonlinear, multivariate, and spatially-dependent time-frequency functional methods
(University of Missouri--Columbia, 2013)
through carefully chosen basis expansions (empirical orthogonal functions) and feature-extraction stochastic search variable selection (SSVS). Properties of the methodology are examined through an extensive simulation study. Finally, we illustrate...
Dance-based therapy to decrease fall risk in older persons
(University of Missouri--Columbia, 2010)
persons. This study was an extension of a pilot study conducted in 2008, which has been translated into practice with dance-based therapy offered weekly in a Program of All-inclusive Care for the Elderly (PACE). As demonstrated in the pilot session...
The log in my eye : awareness, acceptance, and correction of partisan political bias
(University of Missouri--Columbia, 2019)
People are often unaware of or under-estimate their own cognitive biases, suggesting that political bias -- measured by the influence of irrelevant political information on otherwise non-political judgments -- may be ...
Development and analysis of ZnO-based semiconductor photodetectors for UV detection
(University of Missouri--Columbia, 2010)
The objective of this thesis is to develop ZnO-based semiconductor photodetectors for UV detection with low dark current, high responsivity, and fast response time. To achieve this objective, an understanding of carrier ...
