Profiling predictors of speech intelligibility in individuals with Parkinson's disease
(2020-05)
The current study investigated the perceptual predictors of speech intelligibility in individuals with Parkinson's disease and the magnitude of each in predicting speech intelligibility as perceived by semi-trained listeners. ...
Disasters and dropouts: The effect of disasters on Texas high school dropout and graduation rates 2010-2018
(2020-12)
Schools contain some of the most vulnerable populations in a community. When a disaster strikes, the focus is primarily on the physical damages caused by the event. Previous studies that use test scores to measure disaster ...
Sensitivity of winter wheat (Triticum aestivum L.) to quizalofop-p-ethyl in central Oklahoma and Kansas
(2020-12)
CoAXium® Wheat Production System, developed by Colorado Wheat Research Foundation, Albaugh Chemical, and Limagrain, is a new herbicide tolerant wheat that allows for the use of Aggressor^TM herbicide [active ingredient: ...
Use of a novel approach to assess changes in local food sourcing in a sample of Oklahoma school districts
(2020-12)
The purpose of this study was to identify changes in the extent to which Oklahoma schools were using locally grown foods, what specific foods they were purchasing and by what methods they were making the purchases. Barriers ...
Drought-induced epigenetic modulation and transcriptional variation of winter wheat
(2020-12)
The worsening climate uncertainty has exacerbated environmental stress, and the accompanying extreme weather disasters have damaged crop production across the globe. The yield production of wheat, one of the world's most ...
Informational environments and anti-predator behavior in Physa acuta
(2020-12)
Informational environments can alter how well predators and prey can find and avoid each other, and change how much certainty individuals experience. The impacts this has on ecological dynamics needs more investigation. ...
Biostratigraphically constrained ages of Mississippian mixed carbonate-siliciclastic sequences, STACK play, Anadarko basin, Oklahoma
(2020-05)
The ages of Mississippian stratigraphic intervals within the STACK play of the Anadarko basin remain poorly understood due to the lack of biostratigraphic constraints. Godwin (2018) refined outcrop stratigraphy of Meramecian ...
Durability evaluation of concrete sealed with polyurea polyaspartic coatings
(2020-05)
For this project, the performance of various polyaspartic coating materials was investigated. Motivation for this study was to assess various options for the containment of concrete within bridge parapet walls to prevent ...
Improving the water quality in the Lake Hudson Watershed in Mayes County, Oklahoma
