An in depth evaluation of internal criteria for determining the number of clusters in a data set
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Clustering procedures partition data sets into groups, minimizing the distance within clusters while maximizing the distance between clusters. Clustering can be a powerful tool...
Impacts of Precipitation, Land use Land cover and Soil type on the Water Balance of Lake Chad Basin
(2013)
Lake Chad Basin (LCB) has experienced drastic changes in land cover and poor water management practices during the last 50 years. The successive droughts in the 1970s and 1980s resulted in a decrease in surface water and ...
Essays on behavioral finance
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation consists of three essays on behavioral finance. In the first essay, we proposes a new daily market-level investor sentiment index (Photo Pessimism) constructed...
Ambulatory assessment of physical pain, emotional distress, and alcohol use
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The available research suggests that many individuals with chronic pain drink alcohol to manage their pain. However, few studies have examined the association of alcohol and pain...
Pluton source varition over two magmatic pulses in the white-inyo range, central-eastern California : implications for paleozoic and mesozoic tectonic reconstructions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation uses compositions of plutons in the White-Inyo Range (WIR) of central-eastern California, which is an important tectonic boundary as it is the easternmost...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
question of how pre-existing topography controls lava flow system structure in volume-limited flows (Soldati et al., accepted). I concluded that a steep slope results in a single, stable channel, whereas a gentle slope results in an unstable, braided...
Seasonality and elevational migration in an Andean bird community
(University of Missouri--Columbia, 2010)
Life history strategies of many birds in the Neotropics remain poorly known. In particular, details on the seasonal movements of individuals and populations within the Neotropics remain largely unknown, including short-distance ...
Entrainment and transport of coarse stream bed material in a fluviokarst watershed, south-central Missouri : a tracer particle study
(University of Missouri--Columbia, 2010)
Plateau of south-central Missouri, and Bear Cave Hollow (BCH), one of TCC's surface drainage streams, bed load entrainment and transport dynamics of mainly siliciclastic material, was evaluated using hydrological measurements and 670 painted tracer...
Assessing the Impact of Changing Climate on Agriculture in Missouri and the use of Crop Insurance as Adaptation Strategy (1980-2010)
(2015)
as an adaptation strategy by farmers in Missouri is driven primarily by the volume of crop production and not vulnerability to changing climate....
Statistical and simulation methods for evaluating stationary and mobile work zone impacts
(University of Missouri--Columbia, 2018)
when traffic volumes are under 1400 veh/hr/ln, and preferably under 1000 veh/hr/ln, due to the drastic increase in the number of conflicts. In addition, three data driven models were developed to predict traffic speed inside a MWZ: a linear regression...
A genetic approach to determine river otter abundance in Missouri
(University of Missouri--Columbia, 2010)
's effects on sport fish populations have sparked controversy. The MDC responded by increasing efforts to monitor river otter populations, using latrine site counts to measure relative abundance across several rivers in Missouri. However, the actual number...
Generation, collection and characterization of nanoparticles and their diffusion in arbitrary tumor and normal tissue geometry
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nanoparticles have unique electronic, optical, mechanical, magnetic and chemical properties that are significantly different from those of the bulk materials. Because of this...
Influence of herbicides application on weed and tall fescue management and grazing distribution in Missouri pastures
(University of Missouri--Columbia, 2012)
One weed that is of concern in Missouri pastures that can be detrimental is Northern dewberry (Rubus flagellaris Willd.). This weed can be detrimental due its production of spines which can injure grazing animals and also humans. Results from our...
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
been proposed as indicator taxa as they are reliant on insect food reserves and have recently experienced population declines. Thus, we developed two studies in floodplain wetlands to quantify neonicotinoids in Missouri wetlands and potential effects...
Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
(University of Missouri--Columbia, 2010)
-matrix landscape combinations common in five central Missouri counties; 2) evaluate the temporal occurrence of these mosquito taxa; 3) assess relationships between regional weather factors and the occurrence and abundance of the mosquito fauna; and 4) categorize...
On the ability of rocks to conduct heat in the Lithosphere
(University of Missouri--Columbia, 2019)
This work focuses on creating a model for the conductive thermal transport properties of rocks using measured thermal diffusivity (D) with the Laser Flash Analysis (LFA) method, which eliminates common errors associated ...
Designing a LANDIS PRO harvest module and examining the effects of temporal resolution on simulation outcomes
