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...
Associations between psychosis risk and emotional distress disorders with cortical surface morphometry
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Neuroimaging studies have consistently found structural cortical abnormalities in schizophrenia, especially in structural hubs. However, it is unclear what...
Comparative study of type 2 median crossovers and median u-turns
(University of Missouri--Columbia, 2008)
Many states use rural expressway median crossovers which provide for separation between the two opposing traffic lanes to manage the direct left turn movements between the expressways and cross roads. As the volume increases on the major road...
Coprolites of the late eocene using virtual paleontology from the Pipestone Springs Main Pocket, Montana
(University of Missouri--Columbia, 2022)
volumes and diameters for statistical comparison between the two different size classes of coprolite. In combination with volume renders of the segmented material, we also adopt more traditional methods such as thin-section petrography and scanning...
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...
Development and evaluation of a site stormwater analysis calculator intended for the State of Missouri utilzing regional best management practices
(University of Missouri--Columbia, 2023)
The Site Stormwater with Best Management Practices (BMPs) Analysis Calculator was created to be utilized in the State of Missouri for developing or re- developing property. Simplistic and conservative stormwater evaluations utilizing regional...
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...
Top-soil root architecture characteristics of obsolete and modern soybean cultivars and shoot and seed nutrient contents
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max Merr.) is one of the most important cash crops worldwide. It is widely used to produce oil and protein for food and animal feed. Soybean grain...
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...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)

[EMBARGOED UNTIL 12/1/2024] Positive schizotypy is a trait reflecting increased risk for schizophrenia-spectrum disorders and includes symptoms such as magical beliefs and unusual perceptual experiences. The normative ...
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to quantify water quality in upland...
