Estuarine Microbial Community Composition And Efficiency Changes In Response To Vibrio Parahaemolyticus Exposure, Sarah Mulligan

Theses and Dissertations

Vibrio parahaemolyticus is a pathogenic bacterium whose full impact on natural estuarine phytoplankton communities has not been fully resolved. The primary goal of this research was to test how the addition of V. parahaemolyticus to a natural estuarine microbial community would impact the other microbes present. We hypothesized V. parahaemolyticus exposure would reduce phytoplankton biomass and alter the composition of phytoplankton and bacterial communities. Experimental bioassays (60h) were used to assess the effects of the presence of V. parahaemolyticus . Samples for measurements of chemotaxonomic photopigment concentrations, 16S sequencing-based community composition, photosynthetic efficiency, cell density, and V. parahaemolyticus abundance were …

Becoming Musical: Towards A Typology Of Non-Musical Sounds In Recorded Popular Music, Jacob David Mccooey

Theses and Dissertations

There are many instances in popular music in which traditionally non-musical sounds are used musically. There is currently no research on the types and functions of non-musical sounds used musically (NMSUMs). I have collected and organized a collection of example tracks that contain these NMSUMs and analyzed their functions to determine a typology of these sounds. The analysis of the NMSUMs focused on intertextuality, intratextuality, form, texture, and how the sounds relate to traditional, musical sampling. Throughout the course of the analysis, several trends were distinguished amongst the many tracks gathered, and these trends form the basis of the typology.

Scene Text Detection And Recognition Via Discriminative Representation, Liang Zhao

Theses and Dissertations

Scene texts refer to arbitrary text presented in an image captured by a camera in the real world. The tasks of scene text detection and recognition from complex images play a crucial role in computer vision, with potential applications in scene understanding, information retrieval, robotics, autonomous driving, etc. Despite the notable progress made by existing deep-learning methods, achieving accurate text detection and recognition remains challenging for robust real-world applications. The challenges in scene text detection and recognition stem from: 1) diverse text shapes, fonts, colors, styles, layouts, etc.; 2) countless combinations of characters with unfixed attributes for complete detection, coupled …

Theses and Dissertations

The Perinatal Case Conference (PCC) at Prisma Health-Midlands Maternal-Fetal Medicine (MFM) is a biweekly multidisciplinary meeting to discuss pregnancies with prenatally identified congenital anomalies. Patients are primarily cared for by MFM and may have appointments with various subspecialists during their pregnancy. The goals of the PCC are multidisciplinary collaboration in planning for the management of each pregnancy and familiarizing each practitioner with the pending cases, so if or when intervention is needed, the clinicians are familiar with the case.

Researchers performed a chart review and surveyed patients whose pregnancies were discussed in the PCC to learn the patient’s perspective of …

Learning Through Discourse: Impacting Fractional Understanding Through Virtual Discourse, Laurie A. Gentry-Goodale

Theses and Dissertations

There is a strong need for fifth-grade students to become proficient in mathematical problem-solving using fractional computations because it will have a lasting impact on student achievement. Traditionally, mathematics is taught inside a brick-and-mortar classroom, grounded in rote memorization of facts, rules, and formulas. In recent years, more elementary students have enrolled fully in online learning environments, which emphasize on students becoming problem-solvers, specifically in fractional computation. The NCTM strongly encourages using mathematical discourse as an instructional method but employing mathematical discourse, but its applicability to online math learning is not well understood. This study addressed students' problem-solving skills, mathematical …

The Utility Of Referrals From A State Early Intervention System To A Pediatric Genetics Clinic To Increase Access To Genetic Services, Mikayla Jennings

The Importance Of Sense Of Community In Recovery For Individuals Living With Serious Mental Illness, Natalia Gomez

Theses and Dissertations

People with serious mental illness face a variety of barriers to participating in community life. Some of these barriers include limits in social functioning which can then affect social relationships and life satisfaction (Sanchez et al, 2016). Devaluation based on mental health status is an important barrier to address due to its connection to stigma and relationships. The more an individual fears that they will be undervalued and discriminated against, the more they may fear interacting with others. They may hide that they are in mental health treatment or avoid social encounters that they consider as possibly rejecting. These behaviors …

Planning And Adapting In The Design Process, Lindsay Kay Wilkinson

Theses and Dissertations

The costume design and technology program at the University of South Carolina requires that students extensively learn each area of the profession. The largest growth-inducing experiences and some of the highlights for me were the opportunities to adapt when challenging changes or unexpected twists and turns arose with each production or project. Through my time at the university, I have gained a better understanding of balance between time and stress management, a system for understanding and completing costume-based research, digital rendering, I have improved the communication of my ideas with a director, working out a cohesive look with a production …

The Effects Of High Fat Diet On Lipid Deposition In Skeletal Muscle, Alexander Huss

Theses and Dissertations

By the year 2030, almost 50% of adults in the United States are expected to be obese. Obesity has been shown to increase the risk of several chronic metabolic diseases, several cancers, and is associated with impaired skeletal muscle function and metabolism. Despite this, little it is known about the role of altered muscle lipid homeostasis, lipid droplet dynamics, and lipid droplet-mitochondrial interactions in contributing to muscle dysfunction in obesity. Therefore, we sought to investigate the impact of high-fat diet induced obesity on overall skeletal muscle lipid deposition, intramyocellular lipid droplet content and morphology, and lipid droplet-mitochondrial contact. Male C57/BL6 …

An Emic Conceptualization Of Veteran, “You're Either One Of Two Things; You're Captain America Or You're Broken”, Steven Wahle

Theses and Dissertations

The Global War on Terror (GWOT) conflicts have been sustained by an all-volunteer force for over 20 years. There have been no drafts, war bond drives, nor rationing. This is a departure from previous prolonged military conflicts in U.S. history. Volunteers with veteran status are often venerated publicly to express gratitude for their voluntary military service. However, the criterion for veteran status is inconsistent.

In the U.S., former military members tend to be regarded on one of two ends of a spectrum as archetypes in attempts to honor such service. On one end is the veteran hero veteran to be …

Linguistic Perspectives In Ecuadorian Amazonian Kichwa, Max Nathan Jensen

Theses and Dissertations

Despite the fact that Amazonian Kichwa speakers consider themselves to be both linguistically and culturally distinct from their highland counterparts (Ennis 2020; Wroblewski 2012), relatively little has been done to document their language attitudes and how these attitudes are reflected in their speech. This study shows this to be a valid line of questioning. Using commentary from interviews with Amazonian Kichwa people, I show that views on the status and future of the language are divided, as well as perspectives on the role of non-Kichwa sources like schools and governments in language maintenance. Older and native speakers of Kichwa are …

Deep Learning For Source Localization In A Laboratory Tank, Corey Emerson Dobbs

Theses and Dissertations

Deep learning has been applied to underwater acoustics problems in many forms. One difficulty in applying deep learning techniques to ocean acoustics is the spatially and temporally varying environmental properties. Another challenge is the lack of labeled data for training large networks. The overall goal of this work is to develop deep learning approaches for source localization that can be adaptable to different conditions. In this work, a convolutional neural network was trained on acoustic data measured in a water tank, while the water was at room temperature, to predict source-receiver range. Tests were done to ascertain ideal quantities of …

An Investigation Of University General Education Assessment Practice, Joseph H. Hanks

Theses and Dissertations

Many-facets Rasch modeling (MFRM) is an effective way to compensate for rater effects (e.g., rater leniency/severity) in the ratings assigned during rater-mediated assessment. While a fully crossed MFRM rating design, in which all raters rate every rating object, is the ideal from a psychometric standpoint; fully crossed designs are rarely implemented in practice because of the resource burden they impose on assessment personnel. Thus, incomplete rating designs, where each rater does not rate all rating objects, are the norm. However, unless assessment personnel consciously attend to a variety of aspects of rating design, incomplete rating designs may suffer from design …

Emergent Leadership, L2 Oral Proficiency, And Social Networks During Study Abroad, Nicole C. Whitby

Theses and Dissertations

Research shows that study abroad (SA) provides a unique, yet varied outcome for students seeking to improve their target language oral proficiency during study abroad SA (Freed et al., 2004). Contemporary work in second language acquisition (SLA) during SA has looked beyond individual behaviors of sojourners to analyze social networks as a structure with significant influence on outcomes, yet emergent leadership has not been addressed within social network analysis in SA. To address this gap the current study employed a computational social network approach. This mixed methods study analyzes the social networks of 30 SA sojourners from a large private …

Microbial Hydrolysis Process To Improve Anaerobic Digestion For Biofuel Generation, Caleb Michael Jensen

Theses and Dissertations

Human development results in billions of tons of waste per year, which contributes to major issues such as pollution, climate change, and habitat destruction. In this study, we explored the impact of bacterial inoculation on volatile fatty acid (VFA) production, volatile solids (VS), and gas output in anaerobic digesters under different substrate treatments. Our results reveal that bacterial inoculation significantly boosts VFA levels, especially acetic acid, with both Caldicellulosiruptor bescii and mixed Caldicellulosiruptor, cultures showing notable differences compared to controls, especially in untreated manure and WAS treatments. Acetic acid and VS/TS increased in untreated WAS when inoculated with C. bescii …

Theses and Dissertations

Digital banking is rapidly growing in India, positioning the country as the global leader in digital banking users as of 2022, with approximately 295.5 million users, surpassing the United States by over 70 million. This growth reflects a shift from Omni-channel to Omni-digital banking, where customers exclusively use digital platforms, enhancing digital engagement. However, research specifically focusing on Omni-digital banking behavior remains limited, with most studies concentrating on online and mobile banking.

To address this gap, a study was conducted using a new research model based on UTAUT2 variables, targeting Omni-digital banking customers in Tamil Nadu. A sample of 1,082 …

A Comparative Analysis Of Human And Machine Translation Quality, Catherine Marshall

Theses and Dissertations

A common question raised by both translators and Machine Translation developers is Will Machine Translation (MT) ever attain the level of Human Translation (HT) quality? Researchers have argued that MT will likely never replace HT completely because MT systems cannot anticipate all the specifications for possible translation projects (Melby & Hague, 2019) and because MT systems lack cultural understanding (Latief et al., 2020). Researchers have also argued that the use of machines should be focused on augmenting humans, rather than trying to imitate them (Brynjolfsson, 2022). The purpose of this study is to determine how the quality of MT differs …

Tools For Planning Multi-Axis Vibration Qualification Tests, Marcus Edward Behling

Theses and Dissertations

Vibration qualification testing is necessary to ensure that components will endure vibration-induced damage in flight. Multi-axis tests have shown the potential for improvement over single-axis tests, though they require increased planning. This work focuses on planning three critical aspects of these tests: the amount of operational next assembly to include in the test, the size of shakers to use, and the number of shakers to use. Next assembly selection is studied by varying the amount of next assembly included in the lab test, performing physical tests, and comparing the accuracy of environment reconstruction in each test. In doing so, a …

Sexual Attitudes And Knowledge Of Southern United States College Students On Risky Sexual Behavior: Moderation By Conservative Religiosity, Sex, And Sexual Double Standards, Andreana Durham

Theses and Dissertations

The purpose of the current study was to examine the relation of sexual attitudes and knowledge on risky sexual behavior (RSB), while including sex, sexual double standards (SDS), and conservative religiosity as moderators. Findings suggested that sexual knowledge, sexual attitudes, and conservative religiosity associated negatively with RSB for female participants. SDS positively associated with RSB for male participants. The interaction of sexual knowledge and SDS on RSB was significant in male participants and indicated that higher sexual knowledge is associated with higher RSB when SDS is higher. The interaction of sexual knowledge and conservative religiosity on RSB was significant in …

Third-Grade Choctaw Students’ Perceptions Of An In-School Choctaw Language And Culture Program, Amy L. Pauls

Theses and Dissertations

In the United States, Indigenous language loss is the result of colonization and deliberate eradication by government policies. Many tribal communities engage in activities to curb language shift, including language reclamation or revitalization to restore the vitality of Indigenous languages. Schools for Indigenous children, once the setting for the destruction of their Indigenous identity and language, have increasingly become the medium for language reclamation. Numerous school-based programs have effectively renewed language use, including those in the Hawaiian, Yup’ik, and Navajo language communities (Holm & Holm, 1995; Wilson & Kamanā, 2011; Wyman et al., 2010). Though school-based programs may increase students’ …

Expanding The Emotional Cascade Model Of Borderline Personality Disorder With Negative Thoughts, Thought Control Strategies, Suicide Attempts, And Non-Suicidal Self-Injury, Courtney K. Mason

Theses and Dissertations

Borderline personality disorder (BPD) is an impairing mental illness and has a core component of emotional dysregulation. Evidence suggests the emotional cascade model describes how this emotional dysregulation leads to engaging in risky and life-threatening behaviors, such as non-suicidal self-injury (NSSI). Specifically, this model describes rumination as a cognitive component that links the emotional and behavioral dysregulation. The current study aimed to expand the model by investigating how individuals with heightened BPD traits engage in NSSI and in cognitive strategies to cope with their negative affect. Specifically, it was investigated whether behaviors like suicide attempts and cognitions differentiated between those …

Time After Time: Deciphering Structural Violence And Vulnerability Using Postmortem Recovery Time Data And Demographics Throughout The Southeast Region Of The United States, Elise J. Adams

Theses and Dissertations

Over the last few decades, forensic anthropological research has made significant strides in developing better methods for decedent identification and increasing the accuracy of time since death/postmortem interval (PMI) estimations within medicolegal contexts. Until recently however, there has been little emphasis placed on how socioeconomic considerations might be connected, especially regarding recovery times for individuals from various demographic backgrounds. Using intersectional and biocultural frameworks and data collected from forensic anthropologists and medicolegal labs throughout the Southeastern US, this research aims to decipher the role that inequality, through instances of social vulnerability and structural violence, plays in recovery time data throughout …

Diffusion Of Water Conserving Irrigation Practices In The Mississippi Delta, Eugene Oku

Theses and Dissertations

The expanding irrigated acreage in the Mississippi Delta has resulted in increased withdrawals that exceed the recharge rate of the Mississippi River Valley Alluvial Aquifer (MRVAA), leading to a decline in water levels. This trend poses a threat of rapid depletion, potentially resulting in deteriorating water quality and increased pumping costs in the region. Water-conserving irrigation practices are a key component to any potential solution, promising enhanced water use efficiency and sustainable agricultural practices. Nonetheless, farmers adopt these practices at different times. This study used a duration model to identify the factors that influence the timing of adoption of computerized …

Robust Longitudinal Velocity Control For Advanced Vehicles: A Deep Reinforcement Learning Approach, Fahmida Islam

Theses and Dissertations

Longitudinal velocity control, or adaptive cruise control (ACC), is a common advanced driving feature aimed at assisting the driver and reducing fatigue. It maintains the velocity of a vehicle and ensures a safe distance from the preceding vehicle. Many models for ACC are available, such as Proportional, Integral, and Derivative (PID) and Model Predictive Control (MPC). However, conventional models have some limitations as they are designed for simplified driving scenarios. Artificial intelligence (AI) and machine learning (ML) have made robust navigation and decision-making possible in complex environments. Recent approaches, such as reinforcement learning (RL), have demonstrated remarkable performance in terms …

Reconceptualizing The Relations Between Impulsivity, Psychopathy, Machiavellianism, And Narcissism Using Variable- And Person-Centered Approaches, Karen Kelley

Theses and Dissertations

Psychopathy, Machiavellianism, and narcissism are three personality constructs collectively associated with antagonism, callousness, and engagement in socially aversive behaviors. These overlapping personality constructs are theorized to have features that meaningfully distinguish each of them from one another, such as variations in impulsivity. However, investigating the interrelations between existing measures of psychopathy, Machiavellianism, narcissism, and impulsivity presents several methodological challenges. Five Factor Model (FFM) approaches to these four multidimensional constructs provide a promising avenue for examining the associations between these personality domains and impulsivity. This study examined a comprehensive, multidimensional model of impulsivity (i.e., the UPPS-P model of impulsivity) in relation …

Theses and Dissertations

The annihilation of the Armenian Medieval Cemetery of Jugha, located in the exclave Nakhijevan Autonomous Republic, in the current-day Republic of Azerbaijan, took place between 1998-2006. The systematic structural violence used by the Azerbaijani state, sponsored destruction of Indigenous Armenian cultural heritage, usurpation of sacred spaces, attempted rewriting of history, and reshaped the landscape, therefore distorting reality and memory. This research aims to scrutinize the tactics used by the Republic of Azerbaijan in their erasure of the Old Jugha cemetery and present how not only is this a case of structural violence but also one of landscape structural violence against …

Evaluating The Effects Of Incremental Rehearsal At Increasing Drivers Permit Exam Material Knowledge For Individuals With Asd, Madison Billingsley

Theses and Dissertations

Learning to drive represents a rite of passage for many adolescents and young adults, which increases their access to vocational, education, and social opportunities (Almberg et al., 2015; Cox et al., 2012; Lindsay, 2016). When examining licensure rates for individuals with developmental disabilities and/or Autism Spectrum Disorder, research demonstrates lower licensure rates and more difficulties obtaining licensure (Almberg et al., 2015; Cox et al., 2012). Most research focusses on teaching on the road or simulation based driving skills to increase licensure rates, however little research addresses the barriers these individuals face obtaining their drivers permit (Huang et al., 2012; Pandolfe, …

Toward Privacy-Preserving Component Certification For Metal Additive Manufacturing, Mahathir Mohammad Bappy

Theses and Dissertations

Metal-based additive manufacturing (AM) has emerged as a cutting-edge technology for fabricating complex geometries with high precision. However, the major challenges to the wider adoption of metal AM technologies are process uncertainty-induced quality issues. Consequently, there is an urgent need for fast and reliable certification techniques for AM components, which can be achieved by leveraging Artificial Intelligence (AI)-enabled modeling. Developing a robust AI-enabled model presents a significant challenge because of the costly and time-intensive nature of acquiring diverse and high volume of datasets. In this context, the data-sharing attributes of Manufacturing-as-a-Service (MaaS) platforms can facilitate the development of AI-enabled certification …
