Potential Noise Exposure During Post-Trip Inspection Among Commercial Freight Truck Operators, Makayla Ashley Baker Jun 2026

Potential Noise Exposure During Post-Trip Inspection Among Commercial Freight Truck Operators, Makayla Ashley Baker

ETDs from 2020-2029

Noise exposure is one of the most common occupational hazards. Transportation and mate-rial moving occupations reported exposure to noise levels that ranged from moderate (81.4%), loud (15.9%), to very loud (< 0.5%). This study aimed to assess the working noise environment of freight truck operators while completing post-trip inspection. Area noise sampling was performed while freight truck engines were in idle states. A type 2 sound level meter (SLM) was utilized to record noise levels, positioned at rear of the truck cab with the microphone towards the source at a height of 5 feet. The SLM was set up for three noise metrics: Occupational Safety and Health Administration’s (OSHA) permissible exposure limit (PEL) and Hearing Conservation (HC) action level in addition to the American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit value (TLV). 4 trucks were sampled and for each truck, recording duration lasted approximately 15 minutes, reflecting the time spent conducting post inspections. Data collection included the average sound level (Lavg), A-weighted equivalent continuous sound level (LAeq), and maximum A-weighted sound level (LASmax). The measurements were repeated 3 times for each truck and the data were averaged. Lavg was compared to the three respective occupa-tional exposure limits (OELs), assuming a worst-case scenario. Lavg values of each sampling round among four trucks obtained using the OSHA PEL values ranged from 45.1 to 51.4 dB(A), OSHA HC criteria ranged from 37.8 to 51.9 dB(A), and ACGIH TLV values ranged from 55.5 to 67.9 dB(A). The average LAeq of three sampling rounds of the four trucks ranged from 75.4 to 76.9 dB(A) with Truck 3 having the highest average level. The average LASmax of three sampling rounds ranged from 79.3 to 92.0 dB(A), with Truck 3 having the highest average level. Though none of Lavg averages exceeded the respective OELs, Truck 3 under the ACGIH TLV criterion had the highest Lavg at 51.6.9 dB(A), LAeq at 76.9 dB(A), as well as the highest LASmax at 92.0 dB(A). The elevated sound level may be attributed to engine turnover from automated shutoff in prolonged idle states. Further studies need be conducted to investigate other potential factors such as air-brake systems, engine/cab model and age.

ETDs from 2020-2029

Accurate clinical risk prediction plays an important role in improving patient outcomes, particularly in perioperative settings where early intervention can influence care decisions. Although machine learning has shown promising results using electronic health record (EHR) data, its use in clinical practice is often limited by complex development processes, the need for hyperparameter tuning, and variability in performance across datasets. These challenges are especially relevant in data-scarce clinical settings. This thesis evaluates TabPFN-2.5, a transformer-based tabular foundation model designed to perform classification without dataset-specific training. The model was applied to two real-world perioperative prediction tasks: unplanned care escalation (UCE) following post-anesthesia …

Leadership In Parent Engagement: A Phenomenological Study Of School Principals’ Preparedness To Lead Parent Engagement, Aqila Malpass

ETDs from 2020-2029

Researchers consistently report a strong positive correlation between parent engagement and student achievement. When parents are engaged, students benefit in all grade levels and backgrounds (Auerbach, 2010; Epstein, 2011; Henderson & Mapp, 2002; Jeynes, 2005; Weiss et al., 2010). Policy-makers and educators acknowledge the influence of parent engagement on student outcomes (Mapp, 2012). Consequently, communities need effective parent engagement systems and structures within their schools. Principals should understand parent engagement and be equipped to lead its implementation in their schools. It is also necessary to identify key training and support conditions that help to equip principals to lead effective parent …

Learnable Structured Attention For Student-Aware Knowledge Distillation In Dense Prediction, Chen Liu Jun 2026

Learnable Structured Attention For Student-Aware Knowledge Distillation In Dense Prediction, Chen Liu

ETDs from 2020-2029

Dense prediction tasks, including object detection and semantic segmentation, require models to produce structured predictions and are widely used in real-world vision applications. Although deep networks have achieved strong performance on these tasks, their high computational cost limits deployment on resource-constrained systems such as autonomous-driving vehicles. Knowledge distillation (KD) addresses this issue by transferring knowledge from a large teacher model to a compact student model. However, existing distillation methods for dense prediction face greater challenges than those for classification due to the more complex task requirements. To overcome the challenges, this thesis presents a unified study of adaptive distillation for …

Investigating The Role Of Centromere Deletion In Chromosome Segregation, Azait Imtiaz

ETDs from 2020-2029

Centromeres are critical genomic regions responsible for ensuring accurate chromosome segregation during cell division. Disruptions in the structural or functional integrity of centromeric DNA could impair kinetochore assembly, leading to chromosome missegregation and chromosomal instability (CIN), a hallmark of various human diseases, including systemic sclerosis (SSc). This study investigated the contribution of centromeric DNA damage and deletion to CIN and explored potential pathogenic mechanisms relevant to SSc. We utilized hTERT-immortalized fibroblast cell lines (CHON-002 and BJ-5ta) to implement two complementary approaches: (i) treatment with bleomycin, a chemotherapeutic agent known to induce DNA double-strand breaks (DSBs), and (ii) targeted deletion of …

Altered But Adaptive: Network Integration In Pediatric Acute Lymphoblastic Leukemia Survivors A Diffusion Mri Graph Theory Analysis, Amanda Cook

ETDs from 2020-2029

Pediatric acute lymphoblastic leukemia (ALL) survivors face treatment-related risk for late-emerging cognitive difficulties. Chemotherapy can disrupt white-matter structure leading survivors to experience subtle but persistent challenges with processing speed, working memory, and executive functioning. However, cognitive outcomes vary widely even among survivors with similar treatment exposures. To better understand this variability, this study examines how the brain adapts after treatment and how that adaptation is shaped by the environment. This study used diffusion magnetic resonance imaging (MRI) connectomics to characterize white matter network organization in 18 pediatric ALL survivors compared with 20 typically developing controls (ages 10-18). Structural connectomes were …

Mechanisms Of Cyst Initiation And Expansion In Polycystic Kidney Disease: Alterations In Tubule Flow Dynamics And P21- Driven Epithelial Reprogramming, Isis Thomas

ETDs from 2020-2029

Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited disorder characterized by progressive cyst formation, kidney enlargement, and eventual renal failure. Mutations in PKD1 or PKD2 disrupt polycystin-mediated mechanosensory signaling in renal epithelial cells, altering calcium signaling, epithelial architecture, and cellular homeostasis. Although cyst expansion has historically been attributed to epithelial hyperproliferation or tubule pinching off to form a cyst that no longer remains connected with the tubule, the early physiological and molecular events that initiate cyst formation remain incompletely understood. This dissertation investigates how alterations in tubule flow dynamics and epithelial stress responses contribute to cyst initiation and …

Holding The Dying: Worldview, Community, And The Practice Of End-Of-Life Doula Care, Amy J. Shields

ETDs from 2020-2029

As populations age and chronic illness increasingly characterizes the final stages of life in the United States, end-of-life doulas (EOLDs) have emerged as non-medical practitioners who support dying people and their families through education, companionship, advocacy, and ritualized care. Drawing on a thematic analysis of 18 semi-structured interviews with practicing EOLDs across the United States, this thesis examines how EOLDs conceptualize a “good death,” navigate emotionally intensive work, and sustain themselves in an unregulated and often marginal professional landscape. Situating EOLD practice within anthropological scholarship on death and dying, the study highlights the ways EOLDs challenge dominant biomedical narratives that …

Enhancing Dynamic Balance And Mobility In Adolescents With Cerebral Palsy Or Spina Bifida, Phuong Thi Minh Quach

ETDs from 2020-2029

Cerebral Palsy (CP) and Spina Bifida (SB) are among the most prevalent pediatric neuromotor impairments, posing significant challenges to independent mobility and dynamic balance. Although arising from different neurological origins, CP from non-progressive brain disruptions during development and SB from lower motor neuron lesions in the neural tube, both the conditions often lead to similar functional limitations, including muscle weakness, impaired gait and limited mobility. Affected children typically exhibit compromised postural control and an increased dependence on assistive devices. Over time, this decline in independent physical activity often triggers secondary health issues, such as early onset of osteoporosis, hypertension, and …

The Role Of 14-3-3 Proteins In The Pro-Inflammatory Response Of Microglia And The Neuronal Stress Response To Trichloroethylene Exposure, William Stone Jun 2026

The Role Of 14-3-3 Proteins In The Pro-Inflammatory Response Of Microglia And The Neuronal Stress Response To Trichloroethylene Exposure, William Stone

ETDs from 2020-2029

ABSTRACT This dissertation examines how 14-3-3 proteins, with a focus on the 14-3-3θ iso-form, regulate signaling pathways relevant to neurodegeneration. While tradition-ally described as molecular hubs that organize protein–protein interactions, our work reveals how 14-3-3 function is shaped by environmental insults, namely bac-terial and neurotoxicant exposures, and how its disruption contributes to disease-associated processes. Two complementary approaches were used, focusing on microglial inflammatory signaling and neuronal responses to an environmental neurotoxicant, to define a broader role for 14-3-3 proteins in disease associated pathways in the brain. Chapter I identifies 14-3-3 proteins as modulators of microglial activation. Disrup-tion of 14-3-3 interactions …

Topographical Mobility Envelope Modeling And Geometric Analysis For Off-Road Unmanned Ground Vehicles, Huashuai Fan Jun 2026

Topographical Mobility Envelope Modeling And Geometric Analysis For Off-Road Unmanned Ground Vehicles, Huashuai Fan

ETDs from 2020-2029

This dissertation introduces topographical mobility as a quantitative framework for assessing off-road unmanned ground vehicle performance based on geometric interaction between the vehicle and terrain. Rather than relying on conventional discrete indices, the proposed formulation evaluates mobility directly from vehicle and terrain geometry, expressing vehicle capability in terms of radius constraints implied by its dimensions and suspension state. On the vehicle side, longitudinal and lateral mobility radii are derived analytically from vehicle geometry—wheelbase, track width, ground clearance, and lowest underbody point location—quantifying the minimum terrain radius negotiable without underbody interference. Suspension state is shown to alter longitudinal mobility radius by …

Statistical Methods For Mendelian Randomization Under Nonlinearity And Non-Normality, Mary Appah

ETDs from 2020-2029

Instrumental variable (IV) methods are widely used for estimating causal effects in observational studies where unmeasured confounding may bias traditional regression estimates. The core idea is to use a variable referred to as an instrument that is associated with the exposure of interest, independent of unmeasured confounders, and influences the outcome only through the exposure. While originally developed in econometrics, IV methods have been increasingly adopted in epidemiology and genetic research under the framework of Mendelian Randomization (MR), where genetic variants, most commonly single nucleotide polymorphisms (SNPs), serve as instruments. MR provides a powerful tool for investigating causal relationships between …

ETDs from 2020-2029

Synthetic cathinones were identified as new psychoactive substances (NPS) in the early warning advisory system by the United Nations Office on Drugs and Crime (UNODC). Synthetic cathinones have been commonly referred to as bath salts, which offered “legal highs” because they were not explicitly scheduled. These compounds were detected dur-ing the screening process in casework and required internal validation for confirmation. 3,4-methylenedioxy-α-cyclohexylaminopropiophenone was the target analyte for this study. It was alternatively named N-cyclohexyl methylone and “cyputylone." The aim of the study was to validate 3,4-methylenedioxy-α-cyclohexylaminopropiophenone into a Standard Operating Procedure (SOP) for identifying synthetic cathinones using gas chromatography/mass spectrometry …
