The Future Is Female: Steam Education Analysis, Diana Krajewski Lockwood

Theses and Dissertations

The purpose of this mixed-methods action research study was to explore the impact of an online STEAM Program for young girls ages 7-10. The researcher sought to understand how girls this age internalize the stereotype “boys are better than girls.” Especially this idea that boys are better in school when it comes to subjects in STEM (Science, Technology, Engineering, and Math). This study aimed to understand if increasing girls’ access to STEAM education made an impact on gender stereotypes and mindsets.

This study could be used as a resource for schools using virtual learning methodologies to deliver instructional content. The …

Geometric Analysis Of The Doppler Frequency For General Non-Stationary 3d Mobile-To-Mobile Channels Based On Prolate Spheroidal Coordinates, Michael Walter, Dmitriy Shutin, Martin Schmidhammer, David W. Matolak, Alenka Zajic

Faculty Publications

—Mobile-to-mobile channels often exhibit time-variant Doppler frequency shifts due to the movement of transmitter and receiver. An accurate description of the Doppler frequency turns out to be very difficult in Cartesian coordinates and any subsequent algebraic analysis of the Doppler frequency is intractable. In contrast to other approaches, we base our investigation on a geometric description of the Doppler frequency with the following three mathematical pillars: prolate spheroidal coordinate system, algebraic curve theory, and differential forms. The prolate spheroidal coordinate system is more appropriate to algebraically investigate the problem. After the transformation into the new coordinate system, the theory of …

Morals ‘Trump’ Party: Make America Cooperate Again, Jered Abernathy

Theses and Dissertations

Conflict between Democrats and Republicans is a central component of the contemporary American political system. Negative feelings and discrimination based on political orientation are at an all-time high, leading otherwise similar Americans to deeply distrust one another. Social identity theory provides a framework for not only understanding how this distrust between partisans persists, but how it may be negated. This study builds on recent work on moral judgments and trust games to create situations to increase trust across party lines. Using an online-experimental design, this study investigates the effects of two types of moral judgments on trust building: 1) moral …

Synthetic Strategies For The Preparation Of Novel Complex Actinide Oxides And Fluorides, Kristen A. Pace

Theses and Dissertations

The steady accumulation of nuclear waste over many decades has yielded a staggering amount of waste that we must contend with, and with the amount of available space in interim storage facilities diminishing, it has become increasingly more urgent to find viable solutions to nuclear waste storage. The vitrification process has been widely adopted for immobilization of high-level waste; however, the process is inadequate for more complex waste streams and the produced glasses exhibit limited loading capacities. To address this, considerable research efforts have been devoted to the development of new materials as prospective waste forms. Crystalline materials are promising …

Development Of A Cfd Model For The Drying Of Aluminum-Clad Spent Nuclear Fuel, Nathaniel Cooper

Theses and Dissertations

The United States Department of Energy (DOE) currently manages approxi- mately 2500 metric tons of heavy metal (MTHM) of spent nuclear fuel (SNF), pri- marily from naval sources and domestic research reactors, and has agreements in place to accept 10,000 MTHM of aluminum-clad SNF from foreign reactors by 2029. However, due to the closure and the Yucca Mountain site and difficulties in the vitrification process, the majority of this fuel is expected to be placed in intermediate dry storage.

Before being placed in interim storage, all assemblies must be subjected to a drying process, either by forced gas recirculation (FGR) …

Learning Programming Through Robots: A Mixed-Methods Study On The Effects Of Educational Robotics On Programming Comprehension And Motivation Of Preservice Teachers, Alex Geoffrey Fegely

Theses and Dissertations

The purpose of this action research was to evaluate the effect educational robotics have on the programming comprehension and motivation of preservice teachers. Computer science is increasingly being integrated into K-8 curricula across the country. However, there are few teachers trained to teach basic computer science concepts. Core subject teachers are being asked to shoulder the load of integrating computer science concepts into their instruction. Educational robotics have gained attention for their potential to aid users with comprehension and motivation while learning to program. This convergent parallel mixed methods research thus investigated (1) the effect of educational robotics on preservice …

Implementation And Evaluation Of Computer-Assisted Science Vocabulary Modules With Students With An Intellectual Disability And Autism: An Action Research Study, Jamie Lee Taber

Theses and Dissertations

Students with disabilities are struggling to meet expectations in science at the national and local level. Many studies have linked difficulties with science content to difficult and technical vocabulary, and this has been evident at the local level, too. To try to improve science instruction for students with disabilities, the purpose of this study was to evaluate the implementation of computer-assisted science vocabulary modules with students with an intellectual disability and autism in an adapted environmental science class. This study aimed to answer how the implementation of computer-assisted vocabulary modules, which adhere to evidence-based practices of special education vocabulary instruction, …

The Effects Of Project-Based Learning In The Intermediate World Language Classroom, Steven Tanner Tucker

Theses and Dissertations

The primary purpose of this action research study was to further examine the reluctance of intermediate language learners in speaking production in their second language. Additionally, with emerging strategies such as project-based learning, the study explored the efficacy of this strategy, specifically in terms of the students’ volition and motivation to produce the spoken language during classroom activities. The goal was to assist educators in discovering new social and constructivist techniques that could potentially foster student engagement and language acquisition, especially in regard to speaking competencies in the foreign language. Undoubtedly, action research was the appropriate method for the current …

Mathematical Modeling Of Lithium-Sulfur Batteries, Niloofar Kamyab

Theses and Dissertations

Energy storage market transformed by utilization of lithium-ion batteries, will demand high and affordable deliverable energy in the near future which it would be impossible for the current employed technologies to meet those needs Among new generation of lithium batteries, high theoretical energy density, good low-temperature performance, and abundance of inexpensive nontoxic raw material, make the lithium-sulfur batteries (LiS) a promising candidate to outperform the current lithium-ion batteries and transform the technology of the future. However, the problems and challenges that LiS batteries are currently facing with, which stem from the inherent complex mechanism of these cells, are hindering their …

Volume Frequency Response Method For Determining Mass Transfer Mechanisms Of O2 In Carbon Molecular Sieve 3k172, Olivia Smithson

Theses and Dissertations

Carbon molecular sieves (CMS) have grown more desirable over the years as an adsorbent for industrial separation processes as CMS technology has advanced. CMS is commonly used in nitrogen inerting (i.e, oxygen removal from air), carbon dioxide removal from methane and oxygen purification. However, knowledge of the dynamic behavior of these gases on CMS is needed to design and operate efficient and effective separation processes. For this reason, the mass transfer resistances within the micropore at both low and high frequencies were characterized using frequency response, COMSOL Multiphysics modeling, and MATLAB optimization , because frequency response methods have demonstrated the …

Maternal Preventive Dental Services Utilization: The Role Of Preconception Oral Health Counseling In And The Association With Birth Outcomes: Evidence From South Carolina Prams, Monique Johnette Williams

Theses and Dissertations

ABSTRACTThe purpose of this study is to examine maternal preventive dental services utilization by analyzing the role of preconception oral health counseling in utilization of dental cleaning services before or during pregnancy and the association of utilization with preterm birth (<37 weeks) and small for gestational age (SGA) (same sex newborns having birth weight for gestational age below the 10th percentile of the reference population as defined by the World Health Organization (WHO)). Studies suggest that unfavorable maternal oral conditions have significance in birth outcomes, specifically periodontal disease (periodontitis), an oral inflammatory condition which is shown to be a risk factor for preterm birth and low birth weight (Dortbudak et al., 2005; Guimarães et al., 2012; Tejada et al., 2012). Dental cleaning before and during pregnancy is effective in the prevention of oral disease including gingivitis and periodontitis (Johnson et al., 2006; Kurien et al., 2013; Steinberg et al., 2013).

Cross-sectional 2012-2015 data from the South Carolina Pregnancy Risk Assessment Monitoring System (SC PRAMS) survey, a population-based surveillance system on prenatal, perinatal and postpartum experiences of resident mothers who recently delivered a live-born infant, were analyzed using weighted analyses in SAS. Analyses included demographic univariate analyses, Rao-Scott Chi-squared tests of significance to study differences between groups, and multivariate logistic …

Incorporation And Measurement Of Uncertainty In Clustered And Spatial Data, Yuan Hong

Theses and Dissertations

Analyzing population representative datasets for local estimation and predictions over time is important for monitoring related public health issues, however, there are many statistical challenges associated with such analyses. Mixed effect models are one of the common options which can incorporate time and spatial effect in the model and related inference is well established.

In the first part of this dissertation, to estimate area-level prevalence using individuallevel data, small area estimation (SAE) with post-stratified mixed effect models were used where sampling weights were also incorporated into it. However, if poststratification which requires more computation effort can improve estimation accuracy is …

Composition Of Musical And Visual Devices To Create Moments Of Resolution In Marching Arts Production Design, Ryan John Williams

Theses and Dissertations

This research study identifies techniques of creating and releasing musical tension in audio-visual performance media, specifically within the marching arts. A successful composition in this medium is defined, in part, by the coordination of effects between pitched musical elements, non-pitched (percussive) musical elements, and movement (choreographed) elements. Such compositions create a concert performance situation in which there is aesthetic gratification and a sense of sophistication in which aural stimuli interact in congruence and in conjunction with visual stimuli. By identifying the creative practice through conversation with practitioners, designers, choreographers, and composers, the common practices of the genre can be identified …

Measurements Of Rate Exchange Dynamics In Supercooled Ortho-Terphenyl By Single-Molecule 3d Kinetics And Green’S Functions, Harveen Kaur

Theses and Dissertations

Heterogeneity in relaxation rates is a well-established feature of supercooled liquids. It implies the existence of a rate-exchange process to restore ergodicity, but the experimental characterization of that exchange has been incomplete and controversial. This dissertation develops three-dimensional (3D) correlation functions that provide a well-defined measure of rate exchange from single-molecule measurements. This approach is demonstrated on both single-molecule dichroism measurements and atomistic simulations of molecular rotation in ortho-terphenyl.

The first project develops non-parametric analysis of nonexponential and multidimensional kinetics. The quantification of nonexponential (dispersed) kinetics has relied on empirical functions, which yield parameters that are neither unique nor easily …

Fostering Resilience In Correctional Officers, Jon Thomas Arthur Gist

Theses and Dissertations

A significant portion of the literature regarding corrections emphasizes the negative factors and outcomes related to the job. The career of a correctional officer includes a stressful, demanding, and unpredictable work environment. Correctional institutions are struggling to keep a correctional staff that can adapt to internal and external forces. Several studies have shown that correctional officers frequently encounter severe inmate misconduct, resulting in high levels of stress, low job satisfaction, and intentions of leaving the job. However, research begs the question of what makes a correctional officer resilient and functional at work?

No prior study has applied a mixed-methods study …

On Matters Of Feedback: Supporting The Online Grading Feedback Process With Web-Based, Collaborative Comment Banks, Jennifer Schneider

Theses and Dissertations

This action research study describes how a web-based, feedback comment bank impacts online instructor efficacy as well as attitudes and perceptions associated with the online grading feedback process. Bandura’s work on individual self-efficacy, Tschannen-Moran and Hoy’s work on instructor efficacy, and Hattie’s work on collective efficacy, along with Wiggins and Hattie and Clarke’s work on grading feedback represent the core of the study’s theoretical framework. The study adopted a mixed-methods action research design to examine three research questions: “How does the use of a web-based grading feedback comment bank impact online instructor’s teaching efficacy?,” “How does the use of a …

Sleep Quality And The Prospective Pain-Fatigue Relationship Among Youth With Sickle Cell Disease, Julia D. Johnston

Theses and Dissertations

Youth with sickle cell disease (SCD) are at increased risk for poor psychosocial and functional outcomes due, in part, to disease effects like vaso-occlusive pain crises, fatigue, and poor sleep quality (Brown, 2006). A growing body of literature has examined temporal associations between pain, sleep quality, and mood using daily diary studies (Valrie, Gil, Redding-Lallinger, & Daeschner, 2007a; Valrie et al., 2019). These studies help to identify how symptoms are prospectively related to each other, but they are often limited to small sample sizes and may lack generalizability. Additionally, despite ubiquitous reports of fatigue among sickle cell patients, few studies …

Distinguishing Neuro-Markers Of Math Learning Disability Using Eeg Coherence, Jessica C. Luedke

Theses and Dissertations

Math learning disability (MLD) is a neurodevelopmental disorder that results from specific cognitive deficits involved with numeric computation and arithmetic that cannot be attributed to low general ability. Although MLD has a significant impact on life outcomes, only a few studies have evaluated unique neurological profile differences between those with and without specific math deficits. EEG coherence has been useful for evaluating neural disconnections in children with neurodevelopmental disorders but has never been used to explain cognitive deficits found in children with MLD. The current study contributed to the literature by evaluating at-rest electrocortical signatures in those with MLD (n …

African American Teachers’ Perspectives On Principals’ Leadership Styles And The Influence On Teacher Morale, Ernestine Young

Theses and Dissertations

Morale is a concept that denotes how workers feel about their work and the environment in which they work (Robbins, 2003). Low teacher morale is not a new problem; however, with increasing frequency of low morale, teachers are affected all over the nation because of the financial and academic toll it has on education. Low morale typically impedes the achievement of the organization’s desired outcome and corresponds with unresolved grievances, attrition, and high absenteeism. Low morale is associated with billions of dollars spent per year. Low morale is due to effects such as stress, teacher burnout, absenteeism, attrition, and small …

Estimation And Inference Under Model Uncertainty, Yizheng Wei

Theses and Dissertations

Chapter 1 of this dissertation proposes a consistent and locally efficient estimator to estimate the model parameters for a logistic mixed effect model with random slopes. Our approach relaxes two typical assumptions: the random effects being normally distributed, and the covariates and random effects being independent of each other. Adhering to these assumptions is particularly difficult in health studies where in many cases we have limited resources to design experiments and gather data in long-term studies, while new findings from other fields might emerge, suggesting the violation of such assumptions. So it is crucial if we could have an estimator …

Engaging Youth And Families Within The Context Of Evidence-Based Treatment (Ebt) Implementation: Examining Integrity Of Engagement Practices To Different Ebt Information Sources, Eleanor Wu

Theses and Dissertations

Promoting and maintaining client engagement has proven to be a significant challenge across community mental health settings, including within the context of implementing evidence-based treatments (EBTs) (De Haan et al., 2013). Few efforts have been made to equip providers with empirically-sourced engagement strategies outside of the limited set of engagement procedures covered in EBT protocols. To inform efforts for improving EBT accessibility, the current study characterizes the delivery of engagement practices from the literature within the context of EBT implementation, and examines provider integrity of engagement practice use according to two information sources (i.e., the provider’s EBT training history and …

Computational Modeling Of Radiation Damage In A Multi-Phase Ceramic Waste Form Using Moose, Zeyu Chen

Theses and Dissertations

Ceramic waste forms have been proposed to replace the traditional glassy waste forms for long term stabilization of radionuclides. These waste forms are constantly exposed to self-irradiation emitted from the constituent radionuclides causing their material properties to change accordingly. It has been known that the radiation damage in waste forms is dominated by alpha particles emitted from transuranic (TRU) radionuclides. Since alpha particles usually have a range of 10~20 μm in such waste forms, some fraction of any non-transuranic containing phases (for a multiphase waste form) will be undamaged (or less damaged) if containing large enough grain sizes. Modeling and …

The Effects Of Super-Resolution Microscopy On Colocalization Conclusions Previously Made With Diffraction-Limited Systems In The Biomedical Sciences, Madison Emily Yemc

Theses and Dissertations

Super-resolution microscopy, also known as nanoscopy, is now established in the field of microscopy. The evolution of super-resolution microscopy techniques has allowed many scientists to peer past the most significant limitation in conventional fluorescence microscopy – the diffraction limit. Super-resolution microscopy systems are able to resolve two points that are less than 250 nm apart, which supersedes the resolution of diffraction limited systems. Colocalization studies are frequently used in the biomedical sciences to measure the close physical association and functional interaction of two biological structures. Previous colocalization conclusions made with conventional fluorescence microscopy are largely based on how the colors …

Identifying Seasonal And Daily Variations In Arg-Containing Bioaerosols Generated During The Wastewater Treatment Process, Mirza Isanovic

Theses and Dissertations

Antibiotic resistance is a growing problem with the current global death count topping 700,000. In the United States alone there are 2.8 million antibiotic resistant bacterial (ARB) infections each year and approximately 35,000 deaths. If current trends continue the global ARB death count will reach 10 million surpassing current chronic disease deaths. Wastewater treatment plants play a vital role in protecting both the environment as well as local communities. The WWTP process allows for the removal of chemicals and contaminants from water that eventually makes its way back into the environment as well as into drinking water plants. Despite the …

Liberalization First, Democratization Later: The Linkage Between Income Inequality, Economic Development, And Democratization, Yi-Tzu Lin

Theses and Dissertations

This dissertation proposes a model of two-stage process of democratization. In the first stage, income inequality is associated with political liberalization, but this association is conditional on economic development. In the second stage, political liberalization is associated with democratization. By looking at 125 authoritarian regimes from 1960 to 2010, I find that in rich countries, high income inequality is associated with low political liberalization, which may stabilize autocratic regimes; while low income inequality is associated with high political liberalization. In poor countries, high income inequality is associated with political liberalization, while low inequality has no effect.

In the second stage, …

Collegiate And Post-Undergraduate Experiences Among African American Stem Alumni At The University Of South Carolina, Baindu Nallo

The method utilized for this qualitative study was phenomenological analysis. Semi-structured interviews were conducted with 10 African American alumni who graduated between 2010 and 2020 and majored in science, technology, engineering, or math (STEM). Critical Race Theory and community cultural wealth served as theoretical frameworks for this research. The findings indicate that African American students: 1) want to smoothly transition from high school to college curriculum being equally exposed to collegiate materials at the high …

Digesting Gender: Gendered Foodways In Modern Chinese Literature, 1890s–1940s, Zhuo Feng

Theses and Dissertations

In this dissertation, I investigate Han Bangqing (1856–1894), Lao She (1899– 1966), and Su Qing’s (1914–1982) works to study the literary representations of how people purchased, prepared, shared, and ate food in different social contexts allowing them to adapt to new gender norms. I contend that the intersection of food, gender and literature stages the process through which people reconciled different and sometimes conflicting gender norms through their everyday eating practices. When encountering new cooking and eating practices in these literary works, people reflect upon their past lives and, wittingly or unwittingly, begin to accept different gender norms, and modify …
