Information, pleasure, and persuasion : how motivations function in talking politics
(University of Missouri--Columbia, 2009)
Scholars have long debated the role that communication plays in the formation and functioning of a democratic system. Philosopher John Dewey (1927) suggested that citizen-to-citizen talk serves as the very foundation of ...
Experiences influencing physician rural practice and retention : a phenomenological study
(University of Missouri--Columbia, 2009)
A physician maldistribution exists when comparing rural with urban areas. It is necessary to ensure rural citizens have available, accessible, and acceptable quality medical care to remedy health disparities resulting from ...
Chemical modifications to produce soy-based polyols
(University of Missouri--Columbia, 2009)
This project comprises several chemical routes to produce soy-based polyols for future use in polyurethane foam applications. Soybean oil was polymerized by heat and catalyst to increase molecular weight, and viscosity for ...
Principal, board member, and staff perceptions of female public school superintendents instructional leadership
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study examined the instructional leadership of female superintendents as perceived by board members, principals and staff members who work directly ...
The user-generated dilemma : can the ways in which media organizations publish audience contributions affect the way the audience feels about the site and their intention to contribute?
(University of Missouri--Columbia, 2009)
More and more media organizations are using the Internet to ask their audiences to submit stories, comments and photographs, but they are seemingly doing it without understanding the implications of their actions. This ...
Molecular basis of protein tyrosine phosphatase inhibition by biologically important small molecules with relevance to cell signaling pathways
(University of Missouri--Columbia, 2009)
Protein tyrosine phosphatase 1B (PTP1B) is an abundant mammalian enzyme and well known to be as a central player in the insulin and leptin signaling pathways. Peracetic acid is a strong oxidant molecule, endogenously ...
Investigation of static interfacial fracture in orthotropic-orthotropic composite bimaterials using photoelasticity
(University of Missouri--Columbia, 2009)
The effects of static Mode I (opening mode) and mixed-mode (both Mode I - opening mode and Mode II - shear mode present) loading on orthotropic-orthotropic bimaterial interface cracks and isotropic-orthotropic bimaterial ...
Effects of personal and environmental factors on social engagement in later life
(University of Missouri--Columbia, 2009)
The study used data from Community Partnerships for Older Adults (CPOA) Program Survey of Older Adults 2002 to identify factors that predict social engagement. Multilevel modeling was used to examine the association of ...
PRIMEGENSv2 : a service based platform using object oriented model view controller design pattern
(University of Missouri--Columbia, 2009)
There are a number of tools and software packages dealing with the problem of efficient primer and probe design. In an era of fast paced research it is rather difficult for any researcher to change their favorite tool. So ...
Monte Carlo neutronic simulations for a new approach to parametric INAA and Mo-99 production feasibility at MURR
(University of Missouri--Columbia, 2009)
A novel approach to parametric instrumental neutron activation analysis at MURR has been established. In particular, a detailed MCNP5 steady-state model of the MURR core was developed. The model, which was based on the ...
Gas sorption in engineered carbon nanospaces
(University of Missouri--Columbia, 2009)
Vehicular storage of gaseous fuels is a key enabling technology for the two pillars of a non-petroleum based transportation economy natural-gas vehicles and hydrogen fuel cell vehicles. My research focuses on the development ...
Surface and deep water circulation in late Cretaceous North Atlantic greenhouse ocean
(University of Missouri--Columbia, 2009)
This research provides the first of its kind empirical data regarding the evolution of Maastrichtian surface to deep ocean circulation in the North Atlantic. Differences in foraminiferal abundances and oxygen and carbon ...
Regulation of calcium signaling by p130PH in astrocytes
(University of Missouri--Columbia, 2009)
Ca2+ signaling is a characteristic form of astrocyte excitability, but its role in ischemia is not clearly understood. Our previous study (Ding et al., 2009) demonstrated that astrocytes exhibit enhanced Ca2+ signaling ...
Statistical analysis for survival data with missing information
(University of Missouri--Columbia, 2009)
As a branch of statistics, survival analysis, which is often referred to as "reliability theory" in engineering, has a long history. While in practical problems, some information might be missing. This dissertation discusses ...
Thermal-mechanical analysis of targets for high volume production of molybdenum-99 using low-enriched uranium
(University of Missouri--Columbia, 2009)
Techenetium-99m is diagnostic radioactive medical isotope that is currently used 30,000 times a day in the United States. All supplies of techenetium-99m's parent isotope molybdenum-99 currently originate from nuclear ...
Propagation of polarized light in skeletal muscle
(University of Missouri--Columbia, 2009)
Skeletal muscle is a very important tissue in animals and humans. Optical polarization imaging is a non-invasive method to study biological tissues and provides unique polarization contrast. An imaging system was developed ...
Pronghorn migration and resource selection in southwestern North Dakota
(University of Missouri--Columbia, 2009)
Wildlife managers need pronghorn (Antilocapra americana) movement data in North Dakota because harvest quotas are based on a summer survey, which might not represent the distribution of pronghorn during the fall hunting ...
Investigating the development and use of phylogenetic representations by college undergraduates in a plant systematics course
(University of Missouri--Columbia, 2009)
Representations are critical tools for visualizing complex scientific knowledge. However, there is limited research investigating how students gain representational competence in biology, specifically in evolution. In ...
Processing of synthetic aperture radar data as applied to the characterization of localized deformation features
(University of Missouri--Columbia, 2009)
Satellite-based Interferometric Synthetic Aperture Radar (InSAR) has been used by the geoscience community for many years to obtain ground deformation measurements of large-scale spatial features. Researchers have also ...
