Graduate Theses, Dissertations, and Problem Reports (ETD)

Elk (Cervus canadensis) reintroductions have been common in the 20th and 21st centuries, yet 40% have failed to establish self-sustaining elk populations due to a lack of post-reintroduction demographic monitoring. Elk were reintroduced to West Virginia in 2016 following more than a century of absence after the species was extirpated in 1875. Elk were translocated to West Virginia from Land Between the Lakes National Recreation Area (LBL) in eastern Kentucky and from Arizona. The two groups of elk differ in their subspecies, physiology, reintroduction history, connectivity, and habitat. Reintroductions create genetic risks such as the founder effect and …

ABSTRACT

Reassessing Hourly Neurological Assessments: A Quality Improvement Initiative

Haley Lynne Johnson, BSN, RN

Background: Stroke and brain injuries remain among the leading causes of mortality in the United States, accounting for 162,890 deaths in 2021 (Centers for Disease Control and Prevention [CDC], 2021). Although frequent neurological assessments are essential for monitoring patient status, limited evidence supports the prolonged use of hourly neuro-checks (LaBuzetta et al., 2022). Excessive neuro-check frequency has been linked to sleep deprivation, an increased risk of delirium, and inefficient resource utilization (Kishore et al., 2021).

Purpose: This project aimed to assess the impact of …


“We Do Everything Together!”: Examining The Effect Of A Multitasking Chore On Narrative Engagement And Parasocial Relationships With Podcast Hosts, Hailey Morgan Scherer Jan 2025

“We Do Everything Together!”: Examining The Effect Of A Multitasking Chore On Narrative Engagement And Parasocial Relationships With Podcast Hosts, Hailey Morgan Scherer

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examined the link between media multitasking behaviors and the subsequent enhancement of narrative engagement and parasocial relationships with podcast hosts. Research on parasocial relationships has long established that people can develop strong pseudo relationships through aural media, such as radio and podcasts (e.g., Horton & Wohl, 1956). This has often been attributed to the charismatic nature of hosts on audio programs (e.g., Schlütz and Hedder, 2022; Perks & Turner, 2019; Heiselberg & Have 2023), however, the ability of people to listen while they engage in other tasks (e.g., driving or doing chores) can also enhance parasocial bonds. One …


No Man’S A Stone: A Qualitative Approach To Characterizing Masculinity In Older Adulthood, Montgomery T. Owsiany Jan 2025

No Man’S A Stone: A Qualitative Approach To Characterizing Masculinity In Older Adulthood, Montgomery T. Owsiany

Graduate Theses, Dissertations, and Problem Reports (ETD)

Suicide rates are exceedingly high in U.S. older men (aged 65 years and older). In 2020, older men were about 6.5 times more likely to die by suicide than older women and 1.14 times more likely than men aged 18 to 64 years. Masculine norms (e.g., emotional suppression, self-reliance, anger, physical toughness risk-taking behaviors, alcohol misuse) are believed to influence the presentation of mental disorders, such as depression, which has led to the conceptualization of masculine depression. Research on masculinity often focuses on the experiences of younger men, ignoring how gender identities may change as one progresses through adulthood. Meanwhile, …


Computational Approaches For Diagnosing Neurological Impairments And Restoring Functional Movement, Serhii Bahdasariants Jan 2025

Computational Approaches For Diagnosing Neurological Impairments And Restoring Functional Movement, Serhii Bahdasariants

Graduate Theses, Dissertations, and Problem Reports (ETD)

Movement is the primary means by which the nervous system converts intention into interaction with the environment. Voluntary limb motion enables standing, walking, reaching, and grasping—actions that underpin self‑care, communication, and economic participation. When diseases or injuries disrupt the pathways that couple neural commands to muscle forces—whether through cortical stroke, spinal cord injury, or peripheral nerve damage—mechanical outcomes such as weakness, loss of coordination, and ultimately reduced mobility emerge. These impairments cascade into secondary complications, increased dependence on caregivers, and diminished quality of life. Quantifying how the lesion alters the mechanics of movement is therefore essential for designing targeted interventions …

A Limb-Speed-Driven Locomotor Control System And Its Ability To Adapt, Emily Marie Herrick Jan 2025

A Limb-Speed-Driven Locomotor Control System And Its Ability To Adapt, Emily Marie Herrick

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite how simple walking may seem, the locomotor control system is structurally and functionally complex. Its hierarchical organization of supraspinal and spinal networks with forward and feedback pathways has many interactions at multiple levels that are dependent on the dynamics of a high-dimensional musculoskeletal system. Having a comprehensive understanding of sensorimotor integration within a healthy locomotor control system is crucial for understanding changes to the system due to age or neurologic disease and developing effective technologies to recover mobility in those populations. In this dissertation, we address persistent gaps in knowledge pertaining to how the nervous system controls locomotion.

Searching For The "Tender Places": Shoddy, Knowledge, And Material Culture In The Civil War Era, Robert William Novak

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the American Civil War era, shoddy was difficult to understand. It was simultaneously seen as evidence of advancing western civilization as well as a disgusting amalgamation of refuse and disease that threatened those who touched it. Made from shredding woolen rags and tailors’ clippings, the recycled woolen fibers could by applied in myriad woolen blends that came to dominate the ready-made clothing industry that developed through the first half of the nineteenth century. Its application could soften coarse blends and refine the appearance of cheap cloth. When the American Civil War erupted in 1861, however, shoddy came to define …


Expanding The Vibrating Sharp-Edge Spray Ionization Toolkit For Oligonucleotide Characterization, Sultan Mahmud Jan 2025

Expanding The Vibrating Sharp-Edge Spray Ionization Toolkit For Oligonucleotide Characterization, Sultan Mahmud

Graduate Theses, Dissertations, and Problem Reports (ETD)

A gentle or soft Ionization process is a critical component in native mass spectrometry (MS) to lift the biomolecules from the bulk solution into the gas phase environment of the mass spectrometer preserving their shape, topology and non-covalent interactions. Electrospray ionization (ESI) facilitates structural preservation of proteins, nucleic acids and their complexes and as a result it has been extensively used in native MS. However, in negative ion mode, ESI is somewhat limited in sensitivity due to corona discharge effect resulting from the requirement of a high amount of voltage. This often disrupts the ESI process and may not preserve …

Customer Segmentation And Fuel Economy Prediction Using Telemetry Data From Heavy-Duty Trucks, Batishahe Selimi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Heavy-duty trucks constitute only a modest fraction of on-road vehicles, yet their intensive duty cycles and high fuel demands yield a disproportionately large share of transportation fuel use and greenhouse gas emissions. Addressing this imbalance requires data-driven tools that capture the realities of fleet operation and translate complex telemetry into actionable insight.

This dissertation introduces a unified machine-learning framework that operates exclusively on high resolution time-series data collected from fifty-nine diesel trucks deployed across Southern California. It begins by constructing a multi-modal feature space that blends statistical summaries of key engine signals, static vehicle descriptors, and Mel-Frequency Cepstral Coefficients, thereby …


Co-Transmission Is Co-Opted For The Coordination Of Auditory Sensory Integration, Marryn M. Bennett Jan 2025

Co-Transmission Is Co-Opted For The Coordination Of Auditory Sensory Integration, Marryn M. Bennett

Graduate Theses, Dissertations, and Problem Reports (ETD)

Corollary discharge circuits (CDCs) are conserved mechanisms for sensory modulation during species specific behavioral programs. Many behaviors require multiplexed differential sensory modulation for proper execution. Co-transmission of fast and slow neurotransmitters allows for distinct modulation of different downstream targets within one sensorimotor circuit. However, studying co-transmission within the context of modulatory circuits like CDCs requires complete knowledge of behavioral circuits and precise tools for individually determining the implications of each transmitter on its targets. In this dissertation, I used a conserved set of corollary discharge interneurons in Drosophila melanogaster as a model to study the intricacies of sensory modulation through …

The Effect Of Cerebellar Feedback On The Spatial Processing Of Conspecific Signals In The Electrosensory System, Dakota Ray Miller Jan 2025

The Effect Of Cerebellar Feedback On The Spatial Processing Of Conspecific Signals In The Electrosensory System, Dakota Ray Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Animals have evolved sensory systems to help decipher important environmental signals that are vital for their survival. Feedback pathways are necessary to allow these signals to stand out in a noisy background, enabling the animal to focus on them more effectively. The electrosensory system of Apteronotus leptorhynchus allows the fish to sense the modulations caused by other conspecifics to allow for proper responses during social interactions. Electroreceptors detect these EODs, and afferent nerves project these signals to the ELL, where electrosensory information is projected to other parts of the brain. Cerebellar feedback to the ELL allows the suppression of lower …


Reactive Model-Free Control For Underactuated Vehicles Operating In Resource-Constrained Environments, Austin Lane Sponaugle Jan 2025

Reactive Model-Free Control For Underactuated Vehicles Operating In Resource-Constrained Environments, Austin Lane Sponaugle

Graduate Theses, Dissertations, and Problem Reports (ETD)

Buoyancy-driven, underactuated vehicles offer a compelling solution for long-duration autonomous operations in constrained environments. By leveraging buoyancy to generate lift, these vehicles can remain aloft for extended periods with minimal power requirements, making them well-suited for applications in atmospheric monitoring, planetary exploration, and communications. However, their limited actuation authority, strong coupling with environmental forces, and operating domains introduce significant control challenges, including nonlinearity, sensitivity to external disturbances, and limited observability.

This work investigates the design and implementation of lightweight, reactive model-free control strategies that enable robust autonomy in such constrained settings. A digital Extremum Seeking Controller (ESC) is first implemented …
