Behavioral choice and demographic consequences of wood frog habitat selection in response to land use
(University of Missouri--Columbia, 2007)
Land use is a pervasive form of disturbance affecting natural systems on Earth. My dissertation research is set within the context of a large scale project referred to as Land-use Effects on Amphibian Populations (LEAP), where researchers in Maine...
Cognitive radios: spectrum sensing issues
(University of Missouri--Columbia, 2007)
Cognitive Radio can smartly sense and adapts with the changing environment by altering its transmitting parameters, such as modulation, frequency, frame format etc. The main challenges with cognitive radios are that it ...
Identification, characterization and use of novel thermogenetic tools in drosophilia melanogaster
(University of Missouri--Columbia, 2019)
the available tools offer precise temporal and spatial resolution, their caveats lie in the limited number of tools that can be used simultaneously to alter neuronal activity. The overlapping spectrum of activation of optogenetic tools prevents...
Automating traffic studies at modern roundabouts: a feasibility study
(University of Missouri--Columbia, 2007)
, and signal phasing. At a roundabout, counting techniques are much different. This research builds on other academic research to prove the feasibility of creating an automated traffic counting solution that is comprised of readily available parts, and a...
Decomposing individual and group differences of categorical variables with genetic factor model
(University of Missouri--Columbia, 2007)
The method of decomposing individual and group differences on ordered categorical variables into genetic and environmental factors is introduced. Although the genetic factor model is used to identify the relative contributions ...
Is maturing out of problematic alcohol involvement related to personality change?
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Problematic alcohol involvement typically peaks in the early 20s and declines with age. This "maturing out" of alcohol involvement is usually attributed ...
Advanced modeling and optimal control of a cart-double pendulum system
(University of Missouri--Columbia, 2019)
of this research is to design a controller that provides both energy and error minimization for the cart-pendulum, so that its payload moves as if it were floating freely in a microgravity environment (according to Newton's 1st law). The Euler-Lagrange equation...
Motivational differences between self-reported user groups of the MKT Nature and Fitness Trail
(University of Missouri--Columbia, 2007)
The purpose of this study was to determine if there are any significant differences between the walkers, runners, and cyclists using the MKT Nature and Fitness Trail in Columbia, Missouri. This study helps describe the ...
Using nested structures to select models for developmental trajectories of cognitive abilities in adulthood
(University of Missouri--Columbia, 2010)
Change over time can be modeled through a variety of statistical techniques including, but not limited to, linear or quadratic slope-intercept (SI), repeated-measures MANOVA, and single-factor growth models. Choice of ...
Pennies for parks: the effect of social norm theory on donation behavior in Arkansas state parks
(University of Missouri--Columbia, 2007)
Although donation boxes are common in parks, museums, and historic sites, not much is known about how they influence visitor behavior. Perhaps some donation boxes are more efficient at generating revenue than others. The ...
Postconditioning manipulation of context associative strength on conditioned responding in conditioned taste aversion
(University of Missouri--Columbia, 2006)
These experiments examined the effect of manipulating context associative strength on conditioned responding to a conditioned stimulus using a conditioned taste aversion procedure. In Experiments 1and 3, subjects were given ...
Use of different sources and rates of foliar potassium with glyphosate to overcome environmental- and management-induced K deficiency in soybeans
(University of Missouri--Columbia, 2007)
The incidence of potassium (K) deficiency in soybeans [Glycine max (L.) Merr] has increased over the last few years in Missouri and other Midwestern states. Postemergence application of foliar K fertilizer would have the ...
Electrostatically actuated and bi-stable MEMS structures
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Bistable compliant micro-structures offer a tremendous advantage in the industry today, as these structures have an ability to maintain their shape ...
Seasonal variation in nutrient availability and uptake by oak saplings following four nitrogen treatments on Missouri River floodplain
(University of Missouri--Columbia, 2008)
that limit tree growth and survival. A study was established in May of 2007 to evaluate methods of enhancing tree growth and increasing foliar nutrient content of pin oak and swamp white oak saplings by fertilization using chemicals or nitrogen-fixing shrubs...
Simplified model for reinforced concrete beams under catenary action
(University of Missouri--Columbia, 2010)
The purpose of this research is to develop simplified models to predict the load displacement behavior for any reinforced concrete beam on the basis of material, geometric, and design parameters. The proposed simplified ...
Digital literacies and WAC/WID
(University of Missouri--Columbia, 2007)
This thesis defines digital literacies for an audience of educators who want to integrate digital literacies into their existing curriculum. In this discussion, I examine how discipline-based faculty encourage and support ...
Using conflict positioning as a pretreatment in the public's evaluation of crisis management
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] By conducting a controlled experimental design, this study examined the effectiveness of conflict positioning, which was defined by Cameron (2004) as ...
Development of a fluorescence resonance energy transfer optical nanoscale biosensor based on a liquid-core waveguide platform
(University of Missouri--Columbia, 2007)
In order to produce a more versatile, adaptable, and effective method for detection of biological analytes, a self-contained and robust fluorescent optical biosensor architecture utilizing fluorescence resonance energy ...
High strain properties of advanced high strength spot welded steels
