Knowledge discovery with recommenders for big data management in science and engineering communities
(University of Missouri--Columbia, 2020)
in networking performance monitoring (e.g., perfSONAR deployments), it is hard to pinpoint the root-cause analysis in a multi-domain context. To solve this problem, we define a "social plane" concept that relies on recommendation schemes to share diagnosis...
Photosynthesis and heat tolerance of soybean
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Photochemical Reflectance Index (PRI) is determined from canopy spectral reflectance measurements and can provide important information about photosynthesis. The PRI can...
GIS-based, python modeling of the spatial and temporal distribution of water on the landscape for wetlands decision making
(University of Missouri--Columbia, 2020)
Wetlands provide many benefits for humans and the natural environment, but land use changes have reduced their number and areal extent. Interest has grown in examining surface water distribution both spatially and temporally, ...
Essays on machine learning applications in economics : causal inference and prediction
(University of Missouri--Columbia, 2021)
in the curriculum adoption application. As an extension to the existing studies on how curriculum materials affect student achievement, my work compares the results of DML, kernel matching, and ordinary least squares (OLS). In my study, the DML estimators avoid...
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...
Fluctuating asymmetry as a measure of developmental instability in Arikara bioarchaeological assemblages
(University of Missouri--Columbia, 2018)
from skeletal assemblages excavated from numerous Arikara archaeological sites along the Missouri River in South Dakota. These assemblages were selected for this study because they represent a single, culturally and genetically affiliated population...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
Merging technology development of trapped ion mobility spectrometry quadrupole time-of-flight mass spectrometry with biological investigation of Medicago truncatularoot exudates
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] "New commercial ion mobility instrumentation has the potential to improve current analytical techniques, but developments need to be applicable to real-world problems...
Effects of hip joint orientation and skeletal torsion on human locomotor biomechanics and evolution
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] Bipedal locomotion is a defining feature of the human lineage. However, the form of bipedality in different hominin taxa and the timing of emergence of a human-like striding bipedal gait have ...
Middle and late woodland period cultural transmission, residential mobility, and aggregation in the deep South
(University of Missouri--Columbia, 2009)
This research attempts to reconstruct the extent of prehistoric human interaction within the lower Chattahoochee-Apalachicola River valley and neighboring Gulf Coast for the period spanning 200 B.C. to A.D. 1000. Using ...
Reflux, aspiration and respiratory disease in dogs : clinical consideration and advances in aerodigestive diagnostics
(University of Missouri--Columbia, 2019)
The aspiration of gastric contents into the respiratory tract has been associated with the development and progression of multiple respiratory diseases in humans. In veterinary medicine the term "aspiration" is considered ...
DNA methylation in the early porcine embryo
(University of Missouri--Columbia, 2007)
Reproductive technologies such as in vitro fertilization, intracytoplasmic sperm injection, parthenogenetic activation, and somatic cell nuclear transfer are powerful procedures in the production of animals for agriculture, basic research...
Utilizing unoccupied aerial systems and artificial intelligence for monitoring nonbreeding waterfowl abundance in Missouri
(University of Missouri--Columbia, 2023)
aerial survey techniques that are less disturbing to waterfowl, but there is limited information on how waterfowl in winter respond to UAS. Therefore, we compared the behavioral responses of waterfowl to helicopters and UAS on Missouri Department...
Direct contact heat exchanger development
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The purpose of this work was to develop tools that guide the design of a direct contact heat exchanger for small-scale commercial and/or residential HVAC applications...
Ion-selective electrodes for simultaneous real-time analysis for soil macronutrients
(University of Missouri--Columbia, 2006)
Automated sensing of soil macronutrients (i.e., N, P, and K) would allow more efficient mapping of soil nutrient variability for variable-rate nutrient management. This study reports on the development of a sensor array ...
Simulating prehistoric population dynamics and adaptive behavioral responses to the environment in Long House Valley and Black Mesa, Arizona
(University of Missouri--Columbia, 2018)
produce unexpected results, including those that deviate from the population patterns observed archaeologically. Despite these unexpected interactions, the results support the importance of variations in agricultural productivity in driving human...
Effects of prescribed fire on forest soil properties in the Ozark Highlands
(University of Missouri--Columbia, 2020)
/Forest Hills Land Type Association in the Black River Basin of southern Missouri. Weathered from Roubidoux sandstone and Gasconade dolomite, soils at the study sites contain large quantities of coarse fragments and reduced nutrient content. In 2015, fire...
Average treatment effect evaluation with time-to-event data in randomized clinical trials and observational studies
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] The average treatment effect (ATE) is defined as the difference in the expected outcome between individuals receiving the treatment and those not receiving it. As a measure of the impact of a ...
