Reflecting On Design: A Study Of The Relationship Between Beginning Landscape Architecture Students’ Graphic Skills And Self-Efficacy Through Hybrid Assessments And Reflective Writing, Rachel Michelle Nobles
Reflecting On Design: A Study Of The Relationship Between Beginning Landscape Architecture Students’ Graphic Skills And Self-Efficacy Through Hybrid Assessments And Reflective Writing, Rachel Michelle Nobles
Theses and Dissertations
The purpose of this study is to examine the connection between self-efficacy, reflective writing, and graphic quality inside a first-year Landscape Architecture design studio. Reflective writing and self-efficacy can be studied to better understand how to motivate students within a design studio. Bandura (1977) defines self-efficacy as the belief in one’s own capabilities relating to motivation, behavior, and environment. Reflective writing is overlooked as a mode of advancing knowledge in the design process (Lousberg, 2019). The data were collected with pre- and post-semester Likert scale questionnaires, graphic skill-building tests, and reflective writing. To determine growth, the pre-and post-Likert-type questionnaires and …

Exploring Bistatic Scattering Modeling For Land Surface Applications Using Radio Spectrum Recycling In The Signal Of Opportunity Coherent Bistatic Simulator, Dylan R. Boyd
Theses and Dissertations
The potential for high spatio-temporal resolution microwave measurements has urged the adoption of the signals of opportunity (SoOp) passive radar technique for use in remote sensing. Recent trends in particular target highly complex remote sensing problems such as root-zone soil moisture and snow water equivalent. This dissertation explores the continued open-sourcing of the SoOp coherent bistatic scattering model (SCoBi) and its use in soil moisture sensing applications. Starting from ground-based applications, the feasibility of root-zone soil moisture remote sensing is assessed using available SoOp resources below L-band. A modularized, spaceborne model is then developed to simulate land-surface scattering and delay-Doppler …

Metacrisis, Not Civil War: Examining France’S Unrest In June/July 2023, Thomas G. Chevalier
Metacrisis, Not Civil War: Examining France’S Unrest In June/July 2023, Thomas G. Chevalier
Emancipations: A Journal of Critical Social Analysis
In this commentary, I examine the urban riots that took place in France at the end of June and early July 2023 to assess the levels of violence and the response of the French government. I argue that the unrest did not represent the brink of a civil war, as wrongly claimed by dark journalistic assessments and dominant right-wing political discourses, but pertained to a more profound condition of metacrisis (a state where a crisis enters a crisis of its own and a dangerous situation of social strife ensues). Tracing recent discourses and imaginaries of civil war in France and …
Cost Of Care Conversations: Perspectives From Rural Health Care Providers And Older Adult Patients, Karen L. Franck, Christopher Sneed, Lisa Washburn, Ann A. Berry, Victoria Niederhauser
Cost Of Care Conversations: Perspectives From Rural Health Care Providers And Older Adult Patients, Karen L. Franck, Christopher Sneed, Lisa Washburn, Ann A. Berry, Victoria Niederhauser
Journal of Human Sciences and Extension
Older adults often struggle with health care costs. Cost of care (CoC) conversations are conversations between health care providers and patients to discuss direct and indirect costs associated with health care. These conversations have been found to increase patient compliance, but patients and health care providers often do not have these discussions. This article describes a project to provide Extension education to encourage CoC conversations for older adults and health care providers in rural counties in a southern state. To inform educational material development, 125 older adults and 51 health care providers completed surveys about their cost-related barriers to health …

Research Informed Guidelines For Couple And Relationship Education Programs With Arab American Immigrant Couples, Sarah Almalki, Lawrence Ganong
Research Informed Guidelines For Couple And Relationship Education Programs With Arab American Immigrant Couples, Sarah Almalki, Lawrence Ganong
Journal of Human Sciences and Extension
In this paper, we review the characteristics of Arab immigrants and propose guidelines for couple and relationship education (CRE) programs with Arab immigrant couples. Arab immigrants are a heterogeneous group, yet they share common cultural characteristics and family values that are essential to understand when working with them. Generally, CRE programs with immigrated Arabs should be mindful of (1) strongly valued religious beliefs, (2) extended family as a primary source of support and marital problem-solving, (3) the tendency to follow gender-based roles and responsibilities, and (4) Arabic language and communication norms. Family educators and practitioners who work with recently immigrated …

“I Just Kind Of Felt Like Country Come To Town:” College Student Experiences For Rural Students At One Flagship University, Phillip D. Grant, Dena Kniess
The Rural Educator
Rural undergraduate students at flagship universities in the United States are typically outnumbered by their urban and suburban peers. Students from rural demographic backgrounds bring different forms of social and cultural capital to higher education with them. This phenomenological study at a flagship university in the Deep South region of the United States examines their experiences through the lens of Constructed Environment Perspectives to assess how rural students evaluate their sense of fit at an institution of higher education. Rural students in this study noted that they began their first year of postsecondary education with a smaller social network than …
The Benefits Of University Faculty As P-12 Substitute Teachers, Odin Jurkowski, Deanna Jurkowski, Rene Burress
The Benefits Of University Faculty As P-12 Substitute Teachers, Odin Jurkowski, Deanna Jurkowski, Rene Burress
The Rural Educator
The current substitute teacher shortage was exacerbated by COVID-19 and is not expected to improve any time soon. A solution that may benefit both P-12 schools and higher education involves the occasional utilization of university faculty as substitute teachers. This alleviates some of the pressure on school districts in finding substitute teachers while also building relationships, providing university faculty with current classroom experience, and serving as a recruitment pipeline.
Exploring Factors Associated With Academic Motivation And College And Career Readiness Of Rural Adolescents, Peter N. Knox
Exploring Factors Associated With Academic Motivation And College And Career Readiness Of Rural Adolescents, Peter N. Knox
The Rural Educator
Past decades have seen an increase in focus on college and career readiness (CCR) policy and programming to meet the growing demand for a high-skill, global, 21st-century workforce. Recent research indicates many adolescents aspire to succeed in various postsecondary paths, but a persistent gap between aspirations and attainment remains. This is particularly true for traditionally underserved and underrepresented populations, such as those from rural communities. Looking beyond academic metrics such as test scores, grade point averages, and course offerings, this study seeks to address this gap by investigating rural adolescent school context and experience factors that may be associated with …

Endeavors Of Large Family Firms: A Property Rights Perspective Of Internationalization, Vitaliy Skorodziyevskiy
Endeavors Of Large Family Firms: A Property Rights Perspective Of Internationalization, Vitaliy Skorodziyevskiy
Theses and Dissertations
A large number of firms around the world are family firms. Many of these family firms are involved in internationalization strategies. Despite the breadth of knowledge on the internationalization of large family firms, not enough attention has been paid to some of the aspects of internationalization. Specifically, the literature is scarce with respect to understanding the mechanisms that may help or harm family firms in their internationalization strategies and the impact of these strategies on firm performance. In my dissertation, I use property rights theory to argue that family firms are able to minimize their negotiating and policing costs, allowing …

Analysis Of Weather-Related Flight Delays At 13 United States Airports From 2004-2019 Using A Time Series And Support Vector Regression, Caroline E. Sleeper
Theses and Dissertations
This study seeks to investigate weather-related flight delay trends at 13 United States airports. Flight delay data were collected from 2004-2019 and normalized by airport operations data. Using Support Vector Regression (SVR), visual trends were identified. Further analysis was conducted by comparing all four meteorological seasons through computing 95% bootstrap confidence intervals on their means. Finally, precipitation and snowfall data were correlated with normalized delays to investigate how they are related. This study found that the season with the highest normalized delay values is heavily dependent upon location. Most airports saw a decrease in the SVR line at some point …

Monolithic Multiphysics Simulation Of Hypersonic Aerothermoelasticity Using A Hybridized Discontinuous Galerkin Method, William Paul England
Monolithic Multiphysics Simulation Of Hypersonic Aerothermoelasticity Using A Hybridized Discontinuous Galerkin Method, William Paul England
Theses and Dissertations
This work presents implementation of a hybridized discontinuous Galerkin (DG) method for robust simulation of the hypersonic aerothermoelastic multiphysics system. Simulation of hypersonic vehicles requires accurate resolution of complex multiphysics interactions including the effects of high-speed turbulent flow, extreme heating, and vehicle deformation due to considerable pressure loads and thermal stresses. However, the state-of-the-art procedures for hypersonic aerothermoelasticity are comprised of low-fidelity approaches and partitioned coupling schemes. These approaches preclude robust design and analysis of hypersonic vehicles for a number of reasons. First, low-fidelity approaches limit their application to simple geometries and lack the ability to capture small scale flow …

Understanding Dietary And Thermal Influences On Invasive Cichlids In Puerto Rico Reservoir Systems, Jacob A. Moreland
Theses and Dissertations
Jaguar Guapote (Parachromis managuensis) and Amphilophus spp. were assessed for effects of temperature on standard metabolic rate (SMR) and lower dissolved oxygen tolerance (LDOT), efficacy of gastric lavage for diet analysis, and diet in Puerto Rico reservoirs. Fish were acclimated to 22°C, 28°C, and 34°C and SMR and LDOT were measured using intermittent respirometers. Jaguar Guapote acclimated to 34°C had the greatest SMR, with 22°C and 28°C having similar SMR values. Amphilophus spp. acclimated to 28°C were similar to fish acclimated at 22°C and 34°C. Fish were resilient to high temperatures, losing equilibrium more rapidly at the coldest temperature, 22°C. …
Identification And Quantification Of Allelochemicals Associated With Weed Suppression In Sweetpotato, Varsha Varsha
Identification And Quantification Of Allelochemicals Associated With Weed Suppression In Sweetpotato, Varsha Varsha
Theses and Dissertations
Mississippi ranks among the leading states in sweetpotato production in the US. However, managing weeds in sweetpotato fields presents a significant challenge, and the limited availability of herbicides labeled for use in sweetpotato makes it even more challenging. The widespread and repeated use of herbicides has led to the development of weed resistance. In addition, herbicides are incompatible with the organic production system. Finding sustainable weed management strategies to provide weed control options for organic cultivation and detain the development of herbicide-resistant weeds under conventional crop production is imperative. The natural chemicals released by the plants, also called allelochemicals, can …
Determining The Impact Of Post-Harvest Water Management On Chironomid Abundance, Agrochemical Biomass And Potential Trophic Biomagnification, Mason Thomas
Theses and Dissertations
Agriculture has diminished shorebirds’ natural habitat in the Mississippi Alluvial Valley. Remaining natural stopover sites are supplemented with agricultural fields during the fall and winter. This study evaluates the impact of 4 different post-harvest water management strategies on shorebird food abundance and potential agrochemical biomagnification. Chironomid samples estimated abundance, biomass, and chironomid agrochemical concentration in each field. A risk assessment of agrochemical biomagnification to shorebirds was made across all treatments. Of treatments represented on all study sites, winter treatment had greatest chironomid abundance and biomass. Models indicated that days since flood initiation, start date, and temperature are significant predictors of …
The Impact Of Environmental Education Delivery Methods And Outreach Messaging On Attitudes, Interests, And Intended-Behavior Changes Toward Nature, Vanessa Elizabeth Hoffman
The Impact Of Environmental Education Delivery Methods And Outreach Messaging On Attitudes, Interests, And Intended-Behavior Changes Toward Nature, Vanessa Elizabeth Hoffman
Theses and Dissertations
Environmental education (EE) is important for environmental awareness and stewardship. Involving youth and adults in EE ensures current and future generations will conserve natural resources. This thesis explores impacts of delivery methods on participants’ environmental attitudes and behaviors toward nature through middle school classroom- and camp-based EE instruction, focus group interviews with rural minority youth, and adult responses to aquatic conservation outreach messaging. I observed no difference in environmental attitudes between online versus in-person delivery of EE lessons for middle-schoolers. Outdoor-based learning may be more impactful for EE than experiential, classroom-based learning. Focus group outcomes suggested youth EE programs should …
Beyond Algorithms: A User-Centered Evaluation Of A Feature Recommender System In Requirements Engineering, Oluwatobi Lasisi
Beyond Algorithms: A User-Centered Evaluation Of A Feature Recommender System In Requirements Engineering, Oluwatobi Lasisi
Theses and Dissertations
Several studies have applied recommender technologies to support requirements engineering activities. As in other application areas of recommender systems (RS), many studies have focused on the algorithms’ prediction accuracy, while there have been limited discussions around users’ interactions with the systems. Since recommender systems are designed to aid users in information retrieval, they should be assessed not just as recommendation algorithms but also from the users’ perspective. In contrast to accuracy measures, user-related issues can only be effectively investigated via empirical studies involving real users. Furthermore, researchers are becoming increasingly aware that the effectiveness of the systems goes beyond recommendation …
Hydrological And Water Quality Assessment Of Forested Coastal Watersheds, Shreeya Bhattarai
Hydrological And Water Quality Assessment Of Forested Coastal Watersheds, Shreeya Bhattarai
Theses and Dissertations
Coastal regions are at risk of environmental threats. Flooding in coastal rivers is the result of intense precipitation which is triggered by climate change. Coastal watersheds are prone to losing significant amounts of sediment and nutrients because of the shorter transport pathway that drains directly into the coastal water. In this study, the hydrology, flood frequency, and water quality assessment of two coastal watersheds, Wolf River watershed (WRW) and Jourdan River watershed (JRW), were conducted using the Soil and Water Assessment Tool (SWAT). Since WRW and JRW are the main tributaries to fetch freshwater to Saint Louis Bay (SLB) of …
Effects Of Alternative Jet Fuels On Aerospace-Grade Composites: Experimental And Modeling Studies, Naoufal Harich
Effects Of Alternative Jet Fuels On Aerospace-Grade Composites: Experimental And Modeling Studies, Naoufal Harich
Theses and Dissertations
The aviation industry aims to reduce its environmental impact through innovation and research. The usage of composite materials for multiple primary structures represents one such measure. Several alternative fuels were approved and used along with the Federal Aviation Administration (FAA). These alternative fuels are produced from wastes and biomasses. Some alternative fuels were initially only approved as drop-in fuels, meaning they must be blended with conventional fuels to operate. Fuel tanks are usually embedded into the wing structure, which is mainly made of composite materials. These composites tend to absorb fluids it encounters through their matrix phase. The absorption behavior …
Evaluating The Relationship Between Methane Seeps And Seafloor Geomorphology On The Northern Us Atlantic Margin, Gabriel Hernandez
Evaluating The Relationship Between Methane Seeps And Seafloor Geomorphology On The Northern Us Atlantic Margin, Gabriel Hernandez
Theses and Dissertations
Methane seeps are a transport pathway for carbon from seafloor sediments to the marine environment with important implications for global biogeochemical cycling. Accordingly, there is substantial interest in better understanding the processes that control seep location and predicting the distribution of seeps with existing seafloor datasets. Visual evaluation of methane seeps, in multibeam sonar water column data, suggests a spatial relationship between seeps and specific seafloor morphologic features such as ridge crests. In this thesis, seafloor geomorphology at 1996 seep detection sites on the US Atlantic margin was quantitatively characterized by geomorphologic phonotype, bathymetric position index, slope, rugosity, and aspect …
Evaluation Of Conservation Practices Effect On Water Quality Using The Swat Model, Vivek Venishetty
Evaluation Of Conservation Practices Effect On Water Quality Using The Swat Model, Vivek Venishetty
Theses and Dissertations
The deterioration of water quality due to human-driven alternations has an adverse effect on the environment. More than 50% of surveyed surface water bodies in the United States (US) are classified as impaired waters as per the Clean Water Act. The pollutants affecting the water quality in the US are classified as point and non-point sources. Pollutant mitigation strategies such as the selective implementation of best management practices (BMPs) based on the severity of the pollution could improve water quality by reducing the amounts of pollutants. Quantifying the efficiency of a specific management practice can be difficult for large watersheds. …
Limits Of Tectonic Reactivation On Mars Using Earth Analogue Analysis And Numerical Modeling, Jonathan Rich
Limits Of Tectonic Reactivation On Mars Using Earth Analogue Analysis And Numerical Modeling, Jonathan Rich
Theses and Dissertations
Recent geodynamic modeling studies suggest that the geometry of structural landforms in the Ouachita Mountains (OM) has been influenced by the reactivation of a weak scar in the mantle-lithosphere during intracontinental orogenesis. As deformation on one-plate planets such as Mars can be considered intracontinental, and impact cratering deeply scarred the Martian lithosphere, we hypothesize that structural geometries on Mars may also reflect heterogenous networks of lithospheric scarring. To investigate this hypothesis, we model the pre-erosional fold structure of the Maumelle Chaotic Zone in the OM to compare fault and fold geometries with that of the seismically-imaged mantle-lithosphere scar. We then …
Lateral Swelling Pressure In Variably Saturated Expansive Clay, Steven Ray Garrett
Lateral Swelling Pressure In Variably Saturated Expansive Clay, Steven Ray Garrett
Theses and Dissertations
Lateral swelling pressure induced in expansive soils upon wetting can adversely impact the performance and integrity of earthen structures and foundations. The yearly cost associated with damage to structures from expansive clays in the United States is estimated to exceed the loss associated with natural disasters such as earthquakes, floods, and hurricanes. The main objective of this dissertation is to provide new insight into the evolution of lateral swelling pressure in variably saturated expensive soils under infiltration via physical testing. In the first part of this study, a new laboratory-scale testing apparatus was built to measure lateral and vertical swelling …
