Constricting the body politic: Three studies of political communication apprehension and why they matter
(2024-05-10)Much work has been done to capture people’s discomfort with talking about politics. Previous research suggests people are uncomfortable with political conversations for a variety of reasons, though little has been done to ... -
MULTISCALE RESPONSES TO PERTURBATION IN THE CONTEXT OF A HIGHLY CONTAMINATED FIELD SITE
(2024-05-10)Microbes and microbial communities are ubiquitous in the environment and responsible for the cycling of carbon, sulfur, nitrogen, phosphorous, and more, while also being subject to variable conditions ranging from seasonal ... -
TICK ABUNDANCE AND HABITAT DYNAMICS IN URBAN PARKS: A STUDY OF MICRO- AND MACRO- HABITAT INFLUENCES IN THE OKLAHOMA CITY METROPOLITAN AREA
(2024-05-10)Most studies on tickborne diseases in the U.S. have been concentrated in suburban and rural areas. This has led to a lack of understanding about the risks of such diseases in urban settings, where environmental conditions ... -
Design of Precast Post-tensioned Slabs using Lightweight Concrete for Residential Foundations
(2024-05-10)The use of precast concrete in construction is highly favored due to its many benefits, including improved quality control, reduced construction time, increased durability, and sustainability. In Oklahoma, post-tensioned ... -
Effects of Hydrology, Vegetation, and Aeration on Emerging Contaminant Removal from Secondarily Treated Wastewater Effluent in Treatment Wetland Mesocosms
(2024-05-10)Indirect potable reuse is an expanding practice which returns portions of treated wastewater to municipal supplies. However, traditional wastewater treatment is not designed to remove the wide variety of “emerging contaminants” ... -
Impacts of Extractive Activities on Drinking Water and Population Health
(2024-05-10)Extractive activities such as coal mining and hydraulic fracturing (fracking) are common throughout the United States. Much research has found that extractive activities have negative impacts on both ecosystem health and ... -
Enhanced Assessments of Tornado Locations and Damage Using Geospatial Technologies
(2024-05-10)Tornado climatologies represent an important tool for understanding the genesis, behavior, and dissipation of tornados and tornadic storms. The current tornado record is imperfect, but nevertheless useful. I undertook a ... -
An Applied Evaluation of Ecosystem Services Decision-Support Tools
(2024-05-10)Nature's value as an asset is unmistakable, evident through the tangible benefits it provides, such as agricultural yields and tourist attractions. These services, known as ecosystem services (ES), are easy to appreciate ... -
Investigating the Leptinergic Regulation of Weakly Electric Fish Communication Signals
(2024-05-10)Animals expend energy to gain information from their environments and communicate information to conspecifics. Understanding these energy-information tradeoffs is critical for understanding the constraints that shape animal ... -
