Identifying Factors Associated With Time To Diagnosis For Symptomatic Intestinal Malrotation In Pediatric Patients, Katie E. Corcoran

Graduate Theses, Dissertations, and Problem Reports (ETD)

Intestinal malrotation is a rare condition in which the intestines rotate improperly during embryonic development. Intestinal malrotation is typically diagnosed in pediatric patients with an upper gastrointestinal imaging (UGI) series. Longer time to diagnosis of intestinal malrotation increases the risk of mortality and severe morbidity. While the need for timely diagnosis is well-established in the literature, the correlates of time to diagnosis are largely unknown. The classic medical presentation for intestinal malrotation is an infant presenting with green bilious emesis. I hypothesize that time to diagnosis of intestinal malrotation will be longer in symptomatic pediatric patients when they present differently …

Background: Mechanically ventilated patients require supplemental nutrition as an important factor for their overall recovery. Malnutrition in hospitalized patients is reported as high as 35% (Ikram et al., 2022).

Purpose: Lack of an enteral nutrition (EN) protocol has contributed to variability in initiation of EN for post-intubated mechanically ventilated patients.

Intervention: The project interventions are threefold: the development of an EN protocol, EN initiated within 24 to 28 hours for post-intubation patients, and staff understands that EN should be initiated within …

Effects Of Physical Activity And Purpose In Life In Cognitive Aging, Farima Sadeghi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cognitive decline has become a growing public health concern with the increase in aging populations throughout the world. As Physical Activity has shown to be one of the key factors in maintaining and enhancing cognitive health in older adults, this study explores the psychological mechanisms that might underlie this relationship. Using data from the Midlife in the United States (MIDUS) study, the analyses examine whether Purpose in Life mediates the relationship between Physical Activity and both cognitive abilities—Episodic Memory and Executive Functioning, whether age strengthens this effect, and whether Physical Activity itself could act as a mediator. The results showed …

Do Dung Beetles Sink Or Swim: Exploring Dung Beetle Response To Precipitation, Lauren T. Cheshire

Graduate Theses, Dissertations, and Problem Reports (ETD)

Global climate change constitutes a major threat to biodiversity and ecosystem services of many taxa. The Mid-Atlantic region of the US is expecting to see an increase in extreme precipitation events and flooding. Dung beetles (Scarabaeinae) can tunnel below the soil surface allowing for water to dissipate into the soil rather than sit on the surface and add to flooding conditions. They also can decrease methane emission by burying dung and reduce outbreaks of pests that prefer the moist environment of dung. They contribute roughly $380 million in ecosystem services annually in the United States, yet their services may be …

What Does It All Mean? Differences In Self-Defining Memories Between Community And Adjudicated Youth, Hannah Elias

Graduate Theses, Dissertations, and Problem Reports (ETD)

Identity development is driven in large part by self-defining memories, or memories though which we base our definition of who we are (Habermas & Bluck, 2000). In adolescence, cognitive skills are gained that allow us to make meaning, or learn lessons and gain insight, from self-defining memories (Bluck & Habermas, 2001; McLean & Thorne, 2003). To determine whether there are differences in their ability to make meaning from their self-defining memories, this study compares narratives of self-defining memories between community youth and adjudicated youth. Additionally, the ability to be specific in self-defining memory recollection may differ between these groups, which …

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, …

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 …

The People Of The North: Influencer Histories And Miniaturization In Eleventh-Century Italy, Evan Anthony Simonetti

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Norman invasion of Italy in the eleventh century was a process that required political support and legitimacy for its leaders, the Hauteville dynasty. The members of this dynasty either commissioned or financed three individuals as they wrote three respective histories of the Norman conquest in order to accomplish this legitimation. In these sources, each author took inspiration from the classic works of history and poetry of the Greek and Roman world and applied symbolism and direction from their understanding of medieval Christian theology. In addition, these works catalogued examples of events, people, places, animals, and behavior as exotic objects …

Graduate Theses, Dissertations, and Problem Reports (ETD)

State-sponsored, free community college programs have been implemented with the goal of increasing access to higher education, especially for financially disadvantaged students. This study seeks to determine the impact of the implementation of the Tennessee Promise and the Oregon Promise on enrollment and net price by student family income level using a difference-in-differences methodology comparing in-state, public, two-year institutional outcomes with: in-state, public four-year institutions; national, public, two-year institutions; and, public, two-year institutions in states that border Tennessee/Oregon. Enrollment was, on average, found to have increased between 44 and 167 students at Tennessee public, two-year institutions for all students with …

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 …

Neuroendocrine Regulation Of The Luteinizing Hormone Surge And Puberty Onset In Sheep, Max J. Griesgraber

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), and follicle stimulating hormone (FSH) are essential for the reproduction of all mammalian species, including both sheep and humans. GnRH is secreted by hypothalamic neurons into the hypophyseal portal vasculature in a pulsatile manner, which then acts within the anterior pituitary to elicit the release of LH and FSH into wider systemic circulation. In females LH and FSH act on the ovaries to promote estradiol (E2) production, follicular development, and under certain conditions in regard to LH, ovulation. Furthermore, while E2 inhibits GnRH and subsequent LH secretion under most conditions, at high concentrations E2 …

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 …

Economic Behavior And Policy Distortions: Evidence From Firms And Households, Seth Joseph Carter

Graduate Theses, Dissertations, and Problem Reports (ETD)

In Chapter 1, I reopen the question of whether U.S. firms experience effective tax decreases directly resulting from federal lobbying expenditures by introducing more rigorous causal-inference testing. I first model lobbying as a productive input for the legislator, affecting firm tax outcomes by influencing the share of scarce legislative attention afforded to industry tax priorities. Using multi-industry, firm-level data from 2007 to 2022, I exploit percentage changes in non-industry lobbying as a proxy for political competition facing firms through a novel application of Bartik, shift-share instrumental variable estimation and two-stage residual inclusion. Effects of induced firm lobbying shifts on reported …

Three Essays On The Economics Of Crime And Education, Joy Kanengiser

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first chapter investigates the labor market impacts of the Clean Slate Law, a policy designed to reduce barriers to entry by automating the sealing of criminal records. Using IPUMS CPS data from six states, I employ a difference-in-differences framework with individual fixed effects and an event study design to identify changes in employment outcomes. I find that the Clean Slate policy increases employment by 0.33 percentage points and weekly hours worked by 0.44 hours (approximately 24 minutes). Full-time employment rises, while self-employment declines by 0.12 percentage points, suggesting a shift from informal to more stable, formal jobs. These employment …

Autonomous Vehicle Supported Mobility Services For Rural Areas, Alvira Ahmed Tasnim

Graduate Theses, Dissertations, and Problem Reports (ETD)

Autonomous Vehicles (AVs) are emerging as a promising mobility solution to address growing transportation demands, particularly unmet traffic demand in rural areas where conventional transit systems often fall short. Rural areas face unique mobility challenges due to dispersed populations, limited infrastructure, and low/no transit coverage. Existing transit services tend to concentrate around dense urban cores, leaving low-demand areas outside underserved. This spatial undercoverage leads to significant mobility gaps for rural residents. This study examines the potential of AV-based ride-sharing services to address these mobility needs by providing flexible, demand-responsive mobility services where fixed-route transit services are either economically or operationally …

Molecular Characterization Of Fungus-Arthropod Associations, Angie M. Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Arthropods, or phylum Arthropoda, are the largest group of animals, accounting for over three quarters of all animal records on NCBI Taxonomy. And yet, only 40% of all deposited sequences on NCBI Nucleotide come from arthropods. Clearly, arthropods are an understudied group of animals: they are small, often drab, and lead lives very alien to our own. Arthropods have chitinous exoskeletons, segmented bodies, and jointed appendages, and include crabs, barnacles, insects, spiders, and millipedes. Since the era of DNA based studies took off in the 1980s, DNA and other small molecules have been integral to our understanding of the Earth …
