Parent/child distal relationships: a look at communication used before, during, and after a parental absence
(University of Missouri--Columbia, 2005)
This project examined communication in distal parent-child relationships. Distal relationships are relations in which people are physically separated for a period of time. Little research has focused on distal relationships, ...
Traditional institutions, authortarian [sic] legacies, and democratic support in southern Africa
(University of Missouri--Columbia, 2005)
This dissertation investigates citizens' support for democracy in southern Africa and the factors that explain variations in that support. Borrowing insights from the historical institutionalism literature, I argue that ...
The portfolio problem in agricultural cooperatives: an integrated framework
(University of Missouri--Columbia, 2005)
A portfolio problem within agricultural cooperatives arises as a result of the traditional cooperative's property rights structure. As members' investment is tied to patronage, this traditional structure prevents them from ...
Broadband beamforming and direction finding using concentric ring array
(University of Missouri--Columbia, 2005)
Sensor arrays have been used widely in applications including radar, sonar, seismology, biomedicine, communications and imaging. A very popular type of sensor array is circular array, which has almost invariant array pattern ...
Using attitutudes and motivations to segment the landowner audience: a typology of family forest owners in the Missouri Ozarks and description of management and information behaviors
(University of Missouri--Columbia, 2005)
With 74% of Missouri's forestland controlled by family forest owners, understanding this ownership group is important to ensuring the sustainable management of the state's forests. Audience segmentation techniques can help ...
Flourescent molecular rotors as mechanosensors in biofluids
(University of Missouri--Columbia, 2005)
Many disease states have associated blood viscosity changes. Molecular rotors, fluorescent molecules with viscosity sensitive quantum yields, have recently been investigated as a new method for biofluid viscosity measurement. ...
Investigation of a spatial optical pulse collection system in the all-optical analog-to-digital converter
(University of Missouri--Columbia, 2005)
In this research, I conducted a systematic integration of specific calculations for the analysis of the spatial filter that is a critical component of an all-optical analog-to-digital converter. The designed all-optical ...
Neutron diffraction study of load response and residual stresses in WC-(Ni/Co) composites
(University of Missouri--Columbia, 2005)
The in-situ response of WC-Ni and WC-Co composites under compressive loading was measured using neutron diffraction techniques. These measurements give a clear indication of the elastic strain behavior of both the carbide ...
Beautiful choral tone quality rehearsal techniques of a director
(University of Missouri--Columbia, 2005)
What is beautiful choral tone quality? What effective rehearsal techniques might be found if a successful high school choral director could be observed and interviewed? The primary goal of this study was to discover the ...
The poisson problem on Lipschitz domains
(University of Missouri--Columbia, 2005)
The aim of this work is to describe the sharp ranges of indices, for which the Poisson problem for Laplacian with Dirichlet or Neumann boundary conditions is well-posed on the scales of Besov and Triebel-Lizorkin spaces ...
Understanding students' technology appropriation and learning perceptions in online learning environments
(University of Missouri--Columbia, 2005)
Distance education has the unique characteristic of using technologies as the primary means of delivery of instruction and interaction. The present study contributes to research dedicated to explaining or predicting phenomena ...
Examining secondary students algebraic reasoning: flexibility and strategy use
(University of Missouri--Columbia, 2005)
Recent curricular recommendations (NCTM, 2000; RAND, 2003) call for the development of student flexibility in relation to algebraic reasoning. In response to these recommendations, this study focused on the algebraic ...
Structural studies of PMM/PGM from Pseudomonas aeruginosa
(University of Missouri--Columbia, 2005)
The human pathogen Pseudomonas aeruginosa expresses a variety of cell surface polysaccharides, including alginate, lipopolysaccharide (LPS), and rhamnolipid. P. aeruginosa is the primary cause of chronic lung infections ...
Real-time speaker-independent large vocabulary continuous speech recoginition
(University of Missouri--Columbia, 2005)
In this dissertation, a real-time decoding engine for speaker-independent large vocabulary continuous speech recognition (LVCSR) is presented. Three indispensable and correlated performance measurements -- accuracy, speed, ...
Energy metabolism and uranium (VI) reduction by Desulfovibrio
(University of Missouri--Columbia, 2005)
Sulfate reducing bacteria (SRB) of the genus Desulfovibrio can breathe uranium in a manner similar to the way in which we (human beings) breathe oxygen. In respiration, we transfer electrons from food to oxygen, producing ...
Human factors, automation, and alerting mechanisms in nursing home electronic health records
(University of Missouri--Columbia, 2005)
The objective was to evaluate a clinical decision support system in an electronic medical record (EMR) to determine activation frequencies, patterns of activity, and how automated alerting mechanisms affect clinical responses ...
A context-aware notification framework for developers of computer supported collaborative environments
(University of Missouri--Columbia, 2005)
Researchers have identified user presence, awareness, and a sense of community as important components of Computer Supported Collaborative Environments (CSCE) (Dourish & Bellotti, 1992; Erickson & Kellogg, 2003; Moody, ...
Analysis of the Caenorhabditis elegans rpc-1 gene
(University of Missouri--Columbia, 2005)
In eukaryotes, two large subunits form the core catalytic structure of RNA polymerase III (Pol III), which is conserved in other RNA polymerases, Pol I and Pol II. It has been found that Pol III activity is tightly associated ...
Source localization using TDOA with erroneous receiver positions
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Source localization has been an active research for several years. It has applications in many areas such as geolocation and mobile user location. ...
Exploring the validity of the problem solving inventory with Mexican American high school students
(Cambio Center, 2005)
The Problem Solving Inventory (PSI; Heppner & Petersen, 1982) is a widely used measure to assess one's perceived ability in problem-solving behaviors and attitudes in the United States and many other countries. In this ...
