Effect Of Action Selection Demands On The Execution Of Goal-Directed Reaches, James Garrison Riedy

Theses and Dissertations

A well-studied model of cognitive motor function is the process of action selection. It is unclear how the planning demands of a reaching movement interact with the added complexity of s election. Therefore, this thesis investigated the effect of adding selection demands to the performance of skilled reaches in a virtual environment. Thirty young, healthy participants reached ipsilaterally or contralaterally with either their dominant (right hand) or non-dominant (left hand) under two conditions: execute only (EO) and action selection (AS). Selection accuracy was higher for the EO condition than the AS condition for both arms and both directions (left arm: …

Mathematical Analysis Of Electrochemical Systems, Shiv Krishna Reddy Madi Reddy

Theses and Dissertations

A solid electrolyte interphase (SEI) growth model is developed in a mixed modethat contains solvent diffusion through the SEI layer and corresponding solvent reduction kinetics at the SEI/electrode interface. The governing equations are solved by the Landau transformation, which makes the moving layer fixed to predict the open circuit potential, SEI layer thickness, and capacity loss. The estimated parameters fitted with experimental data from the literature are computed using COMSOL and MATLAB. Results show that the mixed mode model predicts lower capacity loss and thinner SEI layer due to its growth under open circuit conditions than previously reported by others. …

Quantized State Simulation Of Electrical Power Systems, Joseph Micah Hood

Theses and Dissertations

An alternative is proposed to the current state-of-the-art simulation methods for the transient simulation of electrical power systems. The proposed method combines the Latency Insertion Method (LIM), the Quantized Discrete Event Specification (QDEVS), and the Quantized State System (QSS) method of integration. Using LIM, the power system state equations are decoupled in a way that allows the formulation of the system into a QDEVS-compliant model, which can then be directly solved with various QSS integration techniques. This combination of methods is called the Quantized DEVS-LIM method, or simply, QDL. A key feature of QDL is the asynchronous updates of all …

Structural And Immunological Characterization Of Inhaled Allergens And Their Complexes With Antibodies, Kriti Khatri

Similarly, airborne allergen Can f 1 from dog (Canis familiaris) is also a major risk allergen which affects 10-20% of the population worldwide (3). Considering the increasing prevalence of inhalant allergens in the environment, antigenic characterization is crucial for improving allergy diagnostics and management. This study focuses …

The Kinetic Control Of Polymer Micelles; Chemical Functionality, Material Interactions, And Equilibration, Taylor Larison

Theses and Dissertations

Polymer micelles have found significant uses in areas such as, energy storage devices, catalysis, opto-electronics, drug-delivery, oil additives, and nanoreactors. In many of these applications the overall micelle size (aggregation number) and chemical functionalization determines performance. To progress towards more advanced materials synthesized from the facile bottom-up approach with polymeric micelles the implementation and study of thermodynamic handles were investigated. Here the kinetic control of micelles was studied across a range of applications; independent control over micelle functionality, the spatial orientation of multiple metal oxide nanoparticles in mesoporous materials via self-assembly, and the use of small-angle neutron scattering (SANS) to …

“We Are Created Inferior To Men”: Leveraging Horsemanship To Reinforce Gender Expectations, 1830-1861, Gabrielle Marie Mccoy

Theses and Dissertations

Horses have played a central role in human society since 3500 BCE when humans began domesticating and riding horses in large numbers. Horses continued to be important to human society during the nineteenth century as people used horses to drive industrialization, manage plantations, and transport goods, among other uses. Although historians and anthropologists have long extolled the horse’s laboring value, this paper views the horse and horsemanship (i.e., horseback riding, horse training) in a social context. Through the examination of newspapers, fictional literature, and manuals, this paper argues that Americans used horses and horsemanship to reinforce antebellum gender expectations. Reinforcing …

Far From Home: The Role Of Travel Distance And Care Fragmentation In Surgical Outcomes For Inflammatory Bowel Disease, Alexander Booth, Henry Colorado, Gayenell Magwood Phd, Rn, Faha, Faan, Erin Forster, Robert N. Axon, Thomas Curran

Publications

BACKGROUND: Fragmented care for inflammatory bowel disease (IBD) is known to correlate negatively with outcomes, but it is unclear which aspects of care fragmentation are relevant and potentially modifiable. Furthermore, there is little data on the relationship between travel distance and the benefits of integrated care models. Hypothesizing care coordination in the preoperative period may have a significant impact on surgical outcomes, we explored associations between integrated care, travel distance, and surgical outcomes. METHODS: A single-center retrospective cohort study of patients undergoing index abdominal surgery was done to compare the rate of surgical complications with and without long travel distance …

Reactive End Capped Polybenzimidazole Oligomers For High Temperature Thermosets And Improved Membranes For Electrochemical Devices, Caroline Marie Rohlfing

Theses and Dissertations

Polybenzimidazoles (PBI) are heterocyclic polymers that possess high thermal and oxidative stability. The inherent strength and chemical and thermal stability of PBI make it ideal for use in extreme environments; however, the current processing of PBI molded parts makes the process practically and economically unfavorable. These intrinsic properties make PBIs of particular interest for many industrial applications, varying from fabrics to membrane materials to molded parts. Processing these molded parts is extremely difficult, as the high glass transition temperature and extremely high melting point (>500°C) of PBI result in poor flow properties of PBI resins even at high temperatures. …

Coaching To Success: Moving From A Fixed Mindset To A Growth Mindset Through Positive Motivation, Shannon Dianna Ramirez

Theses and Dissertations

The purpose of this study was to explore my students’ belief perseverance and fixed mindset and help them shift toward self-determination and a growth mindset. Incorporating goal setting, positive intentions, and coachable techniques in my sixth-grade math class, I collected data through an observation journal, student artifacts, and pre and post assessments. I found that goal setting, positive intentions, and coaching techniques enabled students to shift from belief perseverance toward self-determination that will transfer into life outside of the classroom. My findings showed helping students move from a fixed mindset to one of growth is possible but takes time. Creating …

The Effects Of Gamified Peer Feedback On Student Writing In High School English Language Arts, Kerise Amaris Broome

Theses and Dissertations

National assessments on writing show that student proficiency is low in part because many high school students lack revision skills. Compounding the problem is that as classroom sizes grow, teachers have less time to give the feedback that students need to improve. Peer feedback shows promise in being able to solve the feedback problem, but it must be carefully structured to be effective. The purpose of this action research was to evaluate the impact of gamified peer feedback in a high school English Language Arts classroom at Southern Charter High School. Three research questions guided this study: (1) What impact …

Advancements In Parametric Modal Regression, Qingyang Liu

Theses and Dissertations

This dissertation considers statistical inference methods for parametric modal regression models. In Chapter 1, we motivate the mode as the measure of central tendency instead of the median or the mean with an example. Following the motivational example, we include an overview of existing modal regression models. Later, in the same chapter, we explain advantages of the parametric modal regression models over existing nonparametric modal regression models. In Chapter 2, we address issues in statistical inference brought in by data contaminated with measurement error. With measurement error in covariates, statistical inference methods designed for modal regression models with error-free covariates …

Evaluation Of A Radium-Thorium Disequilibrium Sediment Method Used To Model And Assess Porewater And Submarine Groundwater Exchange In The Coastal Marsh, Madeline R. Bodine

Theses and Dissertations

Ground, pore, and surface water exchange has been extensively studied in beach and near shore environments but has been long neglected in saltmarsh systems due to their complexity. Saltmarsh systems are of particular importance as they are the interface between fresh and saltwater. Saltmarshes impact carbon exchange, release and sequestration, and they process particulate matter. Understanding the characteristics of a marsh system such as the nutrient and particulate loads in conjunction with the flux of water exchange through the marsh provides a deeper understanding of these systems and can impact our understanding of the global water and carbon cycles, as …

Therefore, a list of key steps and functions are created to identify the more difficult and time-consuming phases of process planning. Additionally, a set of metrics must exist by which to evaluate the effectiveness of the manufactured laminate from the machine code created during the Process Planning …

Language Services For Populations With Limited English Proficiency (Lep) And The Necessity For Proper Medical Interpretation With A Focus In South Carolina, Elizabeth Pung

Senior Theses

Linguistically appropriate healthcare is a cornerstone of providing quality patient care. Provider-patient communication is imperative to achieving linguistically appropriate healthcare; unfortunately, language barriers introduced by different spoken languages of patients to their providers hinders this communication. Patients with limited English proficiency (LEP) are ensured accessible healthcare under federal regulations such as the National Standards for Culturally and Linguistically Appropriate Services (CLAS standards); however, a gap between patients with LEP and the healthcare system remains. Not only is there a gap in communication for patients with LEP to their providing physician, but there is a nationwide epidemic resulting in poor health …

The Role Of Religious Coping Resources As Resilience Factors In The Relationship Between Stress And Health-Related Quality Of Life Among Black Americans, Sarah Grace Frary

Theses and Dissertations

Black Americans face health disparities due to a number of systemic barriers across individual, relational, environmental, structural and superstructural levels, and these barriers increase their likelihood of chronic illness and premature mortality. Addressing these disparities is urgently needed. Addressing health promotion through culturally relevant interventions has been shown to be more effective, and one target for health promotion is Health-Related Quality of Life (HRQoL), a multidimensional health indicator that aligns well with many Black Americans’ understandings of health. HRQoL is negatively related to chronic stress. This study aimed to identify factors for effective coping with chronic stress that are culturally …

Engineering Of Bio-Based And Synthetic Polymers: Synthesis And Application In Superabsorbent Materials And Antibacterial Agents, Jihyeon Hwang

Theses and Dissertations

A polymer consists of a large number of monomer units, which can be obtained naturally or via a chemical process called polymerization. Polymers are important materials that are used in our daily life. Life would not be possible without these polymers, either from plant biomass or petroleum-derived synthetic polymers. The substitution of petroleum-derived to biomass-based polymers has been highlighted to mitigate adverse environmental impact. However, the use of bio-based polymers is still a significant challenge for more demanding applications. In this dissertation work, the engineering of both bio-based and synthetic polymers and their properties are investigated.

In Chapter 1, the …

Coordination Environment And Thermodynamics Of Colloidal Quantum Dots In Polar Solvents, Nuwanthaka Prasad Jayaweera Millaniyage

Theses and Dissertations

Colloidal semiconductor quantum dots (QDs) have been extensively investigated due to their attractive properties such as size-tunable absorption and emission spectra, large molar extinction coefficients, and significant photostability. These properties make them promising candidates for optoelectronic, photocatalytic, and biomedical applications. Common synthetic procedures of QDs produce nanocrystals capped with long-chain fatty acid derivatives which are stabilized in high boiling point solvents. Especially for bioimaging applications, the exchange of these native hydrophobic ligands with hydrophilic ligands should be performed, while preserving the smaller hydrodynamic radius. The coordination environment and thermodynamic parameters of the ligand exchanges should be carefully investigated to engineer …
