Characterizing Microplastics In Flood Sediments After Hurricane Helene In Asheville, North Carolina, Abigail Sgan

All Theses

Microplastics are contaminants of emerging concern whose ubiquity across natural environments results in their involvement in many kinds of natural processes, including transportation and deposition in natural systems. The purpose of this thesis is to characterize microplastics and determine the mechanisms that affect their distribution, transport, and sequestration within known Hurricane Helene flood deposits in fluvial and Southern Appalachian wetland environments after Hurricane Helene in Asheville, North Carolina. Four fluvial and four Southern Appalachian wetland environments were sampled after Hurricane Helene. Samples collected in fluvial environments were taken as grab samples from surficial sandy flood deposits left behind by flooding …

Investigating The Effects Of Draw Parameters On The Refractive Index Profiles Of Phosphosilicate Fibers, Brandi Baldus

All Theses

P₂O₅ is a common dopant core material in silica-based glass optical fibers, in part due to its ability to increase the refractive index of silica, required for the fiber to guide light. However, P₂O₅-doped fibers can show a significant decrease in the refractive index profile compared to that of the parent preform. The question arises as to whether the refractive index decreasing could be a direct result of the fiber draw process and, if so, what is it about the draw process that causing such changes in phosphosilicate fibers. More specifically, this Thesis explores the hypothesis that these draw-induced reductions …

Evaluating Pfas And Marine Microbial Interactions In Estuarine Sediments With Varying Urbanization And Assessments Of Microbial Responses To Pfos, Zachary J. Padgett

All Theses

Per- and polyfluoroalkyl substances (PFAS) are a diverse class of synthetic chemicals that have become globally distributed due to their extensive use in industrial and consumer products and their extraordinary resistance to environmental degradation. Their persistence and documented toxicity have made them a growing concern in coastal environments, particularly in estuaries where urban runoff, wastewater, and industrial discharges concentrate these compounds. Estuaries are unique in that tidal mixing and interactions with fine-grained sediments and organic matter promote PFAS retention, while the microbial communities living directly within estuarine sediments are positioned where PFAS preferentially accumulate, creating conditions for prolonged exposure and …

Can Employees Report Stress-Related Problems Without Repercussions? Understanding The Determinants Of Stress Stigma, Kristieona L. Epting

All Theses

Few studies examine the stigma associated with reporting stress-related work concerns, or stress stigma. When employees refrain from communicating their experience of stressors due to the worry of negative repercussions, leaders become unable to gain full insight into the organizational factors causing stress. Learning more about employees’ reluctance to communicate stress concerns can help companies identify workplace stressors. Additionally, prior research has shown that an individual's core self-evaluation (i.e., fundamental evaluation of self) influences how they interpret and react to environmental situations. Individuals with higher levels of CSE may experience fewer adverse consequences from unfavorable job characteristics than a person …

Evaluation Of Ostomy Pouching Change Practices Among Hospital-Based And Community-Based Nurses, Hannah Gerlach

All Theses

An estimated 725,000 to 1 million Americans are living with an ostomy and depend on ostomy pouching systems as part of their daily care.

Many individuals living with an ostomy face long-term challenges in managing their ostomy care, which can negatively affect their health-related quality of life. There is a need to understand how professional experience across different care environments, such as hospital-based and community-based settings, influences ostomy nursing care practices.

This study evaluates how nurses working in hospital-based settings and community-based settings perform …

Evaluating Data Management Practices And Ontology Development For Transportation Safety Assets, Brig Dean Adams

All Graduate Theses and Dissertations, Fall 2023 to Present

Data has begun to permeate transportation agencies, with every process, asset, and event generating a great volume of data. This data helps engineers and decision makers determine maintenance schedules, devise infrastructure investment strategies, improve safety, and plan for future needs. Due to the size of transportation agencies and the diversity of the data they collect, their data is often stored in different systems, managed by different groups, and described using inconsistent terminology. These challenges make it difficult to locate information, combine data from multiple sources, and confidently use data to support important decisions.

This research examined how transportation safety asset …

Causal Discovery In Photospheric Magnetic Field Time Series For Interpretable Solar Flare Prediction, Nathan W. Nelson

All Graduate Theses and Dissertations, Fall 2023 to Present

Solar flares are capable of damaging many valuable resources, including satellites, power grids, and even human lives. Being able to predict solar flares can allow for proactive measures to be taken that can prevent that damage. Many new deep learning methods for predicting solar flares have shown promise in this task, but the decisions they make are harder to explain to humans. This makes understanding why these models make mistakes difficult, which in turn makes fixing and maintaining them more challenging. We test a recent deep learning method that helps discover relationships between different measurements of the Sun as they …

Parental Engagement For Students With Disabilities In Online Learning, Misty A. Benson

All Graduate Reports and Creative Projects, Fall 2023 to Present

Parental engagement for online students with disabilities is critical for their learning success (Tundle et al., 2016). When parents are actively engaged in online learning, their children experience positive learner outcomes (Smith et. al., 2016). Research indicates that students with disabilities are rapidly transitioning to fully online learning, with parents playing an active role as their learning instructors.The implication for parents who choose to enroll their children with disabilities in online learning is greater parental engagement in their child's learning.

"Always Online, Never At Ease: Fear Of Missing Out (Fomo) As A Partial Mediator Between Adverse Childhood Experiences (Aces) And Physical Health, Psychological Functioning, And Psychosocial Adjustment Among College Students", Evelyn Pensamiento

Psychological Science Undergraduate Honors Theses

Adverse Childhood Experiences (ACEs) are potentially traumatic events, such as abuse, neglect, and household disruption, that occur during the first 18 years of life. ACEs have been found to be strongly linked to negative outcomes, such as poor physical health, poor mental health, low self-esteem, low emotion regulation, poor college adjustment, low life satisfaction, and low social connectedness, and high loneliness (Felitti et al., 1998; Carbonell et al., 2018; Cloitre et al., 2019; Mosley-Johnson et al., 2018; Yayan et al., 2019). Previous literature suggests that fear of missing out (FoMO) may help explain some of the negative consequences of ACEs …

An Update On The Role Of Multimodal Analgesia In Perioperative Pain Management, Whitney N. Kuwamoto, Grace C. Eddy, Edward R. Mariano, Eric S. Schwenk

Department of Anesthesiology Faculty Papers

Multimodal analgesia has become a foundational principle of acute perioperative pain management and enhanced recovery and involves the application of nonpharmacologic, pharmacologic, and/or interventional techniques. The overall goal of this approach is to apply a combination of different modalities that target discrete points along the pain pathway and thereby avoid the overreliance on opioids and associated side effects. Since our review in 2018, there have been significant developments that have prompted an updated review of multimodal analgesia. In this article, we identify and summarize important trends that influence the current approach to acute perioperative pain management as well as provide …

Fish Meal Serum Modulates Mitochondrial Membrane Potential In Steroidogenic Cells: Implications For Luteoprotection In Cattle, Tyra Marie Goodluck

Master's Theses

The bovine corpus luteum (CL) is a transient endocrine gland that forms after ovulation and produces progesterone, a hormone crucial for early pregnancy. The cattle industry faces tremendous losses annually due to early embryonic mortality within the first 100 days of gestation, where approximately 16% occur during a critical timeframe known as the maternal recognition of pregnancy (MRP). In a normal estrous cycle, if no viable embryo is present, the uterus secretes prostaglandin F2α (PGF2α) during the late luteal phase, triggering luteal regression. One key action of PGF2α is reducing luteal blood flow, leading to hypoxia. This hypoxic state induces …
