The strength of weak ties in online social networks
(University of Missouri--Columbia, 2009)
The use of online social networks such as Facebook.com are hypothesized to be affecting Robert Putnam's (1995) theory of social capital. The research method is modeled after Dhavan Shah's (2005) Information Communication Participation model...
A pedagogy of freedom : using hip hop in the classroom to engage African-American students
(University of Missouri--Columbia, 2007)
The purpose of this study was to add to the knowledge base an understanding of the impact of culturally-relevant pedagogy, such as hip hop, on African American student engagement. The researcher viewed the study through ...
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. ...
Estimates of school productivity and implications for policy
(University of Missouri--Columbia, 2007)
School productivity was not perfectly estimated because of the sampling error and the measurement error. The traditional Ordinary Least Square (OLS) leaves the estimation of school productivity questionable. Moreover, ...
Action research investigation into teaming in one school district
(University of Missouri--Columbia, 2007)
Working as an insider in collaboration with other insiders, this participatory action research study, through two action research cycles of diagnosing, planning, taking action, and evaluating, explored the implementation ...
Development and implementation of an underwater system for interface wave measurements
(University of Missouri--Columbia, 2005)
Measuring shear wave velocity profiles has become integral to geotechnical site investigation both on land and offshore. Obtaining accurate near-surface profiles in soft marine sediments can be expensive and time consuming ...
Essays on closed-end funds : internal versus external management and insider trading
(University of Missouri--Columbia, 2006)
This dissertation examines two aspects of closed-end funds (CEF). First, a limited number of these funds maintain the historical management structure of internally allocating resources to investments as opposed to hiring an advisor external...
Collaboration and the use of three dimensional interface within a virtual learning environment and the impact on communication and learning: a case study
(University of Missouri--Columbia, 2008)
The purpose of this study was to determine whether collaboration occurred within 3D virtual learning environments. Furthermore, if collaboration occurred were the elements of Nonaka and Takeuchi's knowledge spiral present ...
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 ...
Multi-scale investigations of gray treefrong movements: patterns of migration, dispersal, and gene flow
(University of Missouri--Columbia, 2005)
The movement of individuals within and among populations has been recognized as an important determinant of the persistence of species. Fragmentation of terrestrial landscapes has exacerbated the need to understand the ...
State actions and response following instances of politicide
(University of Missouri--Columbia, 2008)
The development of the international human-rights regime in the second half of the 20th century has led to an increased awareness and rhetorical/normative condemnation of outbreaks of ethnopolitica violence. While concerns ...
Comparison of three tall fescue-based stocker systems
(University of Missouri--Columbia, 2009)
A two-year study was conducted on tall fescue-based pastures to evaluate three approaches to rotationally stocking stocker calves. Within each year, two sets (a spring set and a fall set) of crossbred steers were stratified ...
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...
Noise and signal transmission properties as agents of selection in the vibrational communication environment
(University of Missouri--Columbia, 2007)
Members of the Enchenopa binotata species complex (Hemiptera: Membracidae) are host-specific phytophagous insects that communicate by sending vibrations through their host plants. Successful communication depends on the ...
Computational neural modeling at the cellular and network levels: two case studies
(University of Missouri--Columbia, 2007)
Computational neuroscience provides tools to abstract and generalize principles of neuronal functions using mathematics, with applicability to the entire neuroscience spectrum. Problems at two levels of the neuroscience ...
Fertilizer effects on soil pH, soil nutrients, and nutrient uptake in swamp white and pin oak seedlings on an alkaline Missouri River bottomland
(University of Missouri--Columbia, 2008)
plantings to experience high failure rates due to reasons such as improper soil pH, low nutrient availability, and poor drainage. In this study, fertilizer treatments containing combinations of S, Fe, and N were applied to pin and swamp white oak seedlings...
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 ...
Voices yet to be heard : the educational journeys of older Latino\a undergraduates
(University of Missouri--Columbia, 2007)
With this cross-cultural qualitative study, I sought to understand older Latino\as' undergraduate experiences on predominantly white, non-Hispanic campuses in the Midwest. The eight participants, ages 35-50, were evenly ...
"It's about just staying focused" : how African American gay and bisexual men persist at a predominately white institution
(University of Missouri--Columbia, 2009)
