The Impact Of A Nf-Κb Signaling Inhibitor On The Antibacterial Activity Immune Response In The Cat Flea (Ctenocephalides Felis), Caroline M. Singer

College of Graduate Studies: Theses & Dissertations

Ctenocephalides felis are vectors of several bacterial pathogens that cause disease in humans and animals, including Bartonella henselae and Rickettsia felis. Successful pathogen transmission requires that microbes survive the immune defenses of the flea digestive tract following blood feeding. In insects, humoral immune responses are regulated primarily by the Toll and immune deficiency (IMD) signaling pathways, with the IMD pathway serving as the principal defense against Gram-negative bacteria. Although genomic and transcriptional evidence indicate that cat fleas encode and express components of the IMD signaling pathway, the functional roles of individual pathway components within the flea digestive tract remain …

The Efflorescence Of Apocalypticism (Imminent & Prepping Beliefs): Considering Informational And Motivational Regulatory Mechanisms, James T. Good Mr.

College of Graduate Studies: Theses & Dissertations

In the last quarter of the 21st century, apocalyptic beliefs emerged in scholarly and lay representations notably doubling over the last decade. With nearly forty percent of United States citizen reporting this belief, unfulfilled questions arose: What drives discrepancies in beliefs of an imminent end of the world? Additionally, what drives beliefs in the need to prepare for an end of the world? These individual questions were examined together in this study using Construal Level Theory (CLT) and Regulatory Focus Theory (RFT) in an attempt to identify how psychological mechanisms are significantly affecting the fluctuations, in these self-reported beliefs. A …

Impact Of Religion On Mental Outcomes Among Racial/Ethnic And Sexual/Gender Minority Individuals, Braden J. Waugh, Michael E. Nielsen

College of Graduate Studies: Theses & Dissertations

Marginalized identities (Adams & Miller, 2022) are associated with elevated risks for negative outcomes (Ching et al., 2018; Kayode et al., 2024). Religion has been found to act as a protective and risk factor. Minority Stress Theory (Meyer, 2003) and Intersectionality Theory (Crenshaw, 1991) are used to examine the relationship between identity status and anxiety, prosocial tendencies (PT), and quality of life (QoL). One hundred fifty-two participants were primed with a religious or neutral stimulus, and then answered measures regarding these outcomes (GAD-7, Spitzer et al., 2006; PBIS, Baumsteiger & Siegel, 2019; WHOQOL-BREF, The Whoqol Group, 1998; IFS, Hammer & …

The sample included 7,848 first-time undergraduate students. Multiple linear regression was …

Comparison Of 2000-Meter Row Prediction To Measured Vo2peak During Gxt, Andrew S. Ashley

College of Graduate Studies: Theses & Dissertations

BACKGROUND: Aerobic capacity is essential for the performance of military personnel and first responders. Traditionally, graded exercise tests (GXTs) with metabolic gas analysis have been the criterion-referenced method for assessing aerobic fitness. However, treadmill running and cycle ergometers may not fully reflect the whole-body demands required in tactical environments. Rowing-based assessments and the currently commercially available VO2max prediction formula are widely used across tactical organizations as practical field measures, and most tactical operators are considered inexperienced rowers, which has been minimally examined. PURPOSE: The purpose of this study is to compare measured VO2peak from a rowing GXT with estimated VO2max …

The Effect Of Complexity Of Expert Testimony And The Presence Of A Defensive Rebuttal On Jurors' Decisions In Criminal Trials, Shelby E. Madden

College of Graduate Studies: Theses & Dissertations

Forensic science plays a critical role in criminal trials, yet forensic techniques vary in their reliability. Expert testimony, often held in high regard by jurors, can be a decisive factor in verdicts, but its influence is complicated by factors such as technical complexity, adversarial bias, and heuristic processing. The present study examined how the complexity of prosecution expert testimony and the presence of a defensive rebuttal influenced jurors’ decisions when presented with faulty forensic evidence. Participants (N = 142) were randomly assigned to one of four conditions in a 2 (testimony complexity: high v. low) x 2 (defensive rebuttal …

Emotion Regulation: The Effectiveness Of Reappraisal And Potential Benefit Of Music, Ezra J. Greidinger

College of Graduate Studies: Theses & Dissertations

Literature has supported potential benefits to cognitive reappraisal as a method of emotion regulation, as well as intentional music usage as an enhancer of these effects. It has been suggested that instruction be provided to individuals to use these methods, especially in highly stressed populations (Sakka et al., 2018). However, there has not been an experimental study to follow up on these claims. When instruction is provided, is cognitive reappraisal more effective than naturally developed habits in regulating anxiety, and would music enhance these effects? College students (N = 170) were randomly assigned to three treatment conditions: control, cognitive reappraisal, …

Ni De Aqui, Nor There. Pero As The In-Between, Vanessa Franquez

College of Graduate Studies: Theses & Dissertations

This thesis explores first-generation Mexican American identity as a lived experience of translation and survival. Drawing from Judith Butler, Gloria Anzaldúa, and Jack Burnham, the work frames identity as performative, embodied, and shaped by overlapping cultural systems. Insects function as models of adaptation, camouflage, and defense, paralleling survival strategies such as code-switching and cultural hybridity. Through sculptural processes including tufting, felting, sewing, layering, and the inscription of Spanglish text, repetition and puncture become material metaphors for pressure, repair, and resilience. Language operates as both subject and substance, resisting grammatical purity in favor of hybridity. The work ultimately positions the in-between …

Early Icu Physiological Subtyping From Time-Series Data: A Comparative Study Of Feature Complexity, Predictive Performance, And Model Interpretability, Rojeena Khadka

College of Graduate Studies: Theses & Dissertations

Intensive Care Unit (ICU) patients do not follow a single uniform physiological pattern. Patients admitted with the same diagnosis show different clinical trajectories over time making standardized classification and treatment approaches insufficient. The increasing availability of large-scale electronic health records in MIMIC-IV makes it possible to investigate such heterogeneity through data-driven approach that captures how physiology evolves during the early phase of ICU admission. This thesis compares two analytical pipelines designed to identify physiological subtypes from the first 48 hours of ICU time series data. This study then assesses how well these subtypes predict in-hospital mortality. The first approach, referred …

Modeling Accreditation Standards And Evaluation Methods To Inform Strategic Planning In Public Health Education, Debra Rich

College of Graduate Studies: Theses & Dissertations

Public health has long benefited from the relationship between postsecondary education, accreditation, and government employment. Assessment and accreditation are important tools in postsecondary education to ensure fiscal responsibility, professional competencies, and quality assurance. The competency standards implemented in post-secondary education are not under the direct control of the federal government; however, policy amendments aimed at specific accreditation criteria could result in changes to public health curriculum and create eligibility barriers for students who rely on federal financial support. The Central Washington University Public Health program has provided educational support in professional public health for decades, and there is an increased …

The Influence Of Localized Water Quality On Eastern Oysters (Crassostrea Virginica) And Their Internal Microbiome Under Changing Environmental Conditions, Jessie Rivera Lafreniere

College of Graduate Studies: Theses & Dissertations

Oysters are found ubiquitously in estuaries along the Georgia coast, where marsh morphology and large daily tidal fluctuations create dynamic and stressful conditions to which oysters may be locally adapted. Based on water quality data from the Sapelo Island National Estuarine Research Reserve, it is evident that changing climatic conditions are rapidly causing shifts in water quality that may be adversely affecting oyster health, especially as ocean acidification alters the carbonate buffering capacity, increasing the amplitude of daily pH variations. Importantly, the rate of change of conditions are not uniform within estuaries, varying on spatial and temporal scales. The symbiotic …

Fur-Ever In Memory: College Student Grief And Coping After Pet Loss, Rohit Paruchuri

College of Graduate Studies: Theses & Dissertations

Pet loss is a significant yet often overlooked form of bereavement, particularly among college students who are navigating emerging adulthood. Pets play an important role serving as a source of emotional support and are often viewed as family members; however, grief following pet loss is a type of disenfranchised grief, meaning it is not accepted by the society as something significant and often overlooked when compared to grief following human loss (Spain et al., 2019). Research suggests that grief following pet loss can mirror responses to human loss including sadness, guilt, loneliness, and disruption of daily routines (Eckerd et al., …

Formalizing Asymmetric Control-Telemetry Separation In Distributed Industrial Control Systems, Andrew Manison

College of Graduate Studies: Theses & Dissertations

Distributed industrial control systems often place control and telemetry traffic on the same communication substrate even though the two workloads impose different requirements. Control paths need bounded request-response latency and predictable acknowledgement semantics, whereas telemetry paths benefit from scalable publish-subscribe fanout and tolerance for consumer-side delay. This thesis argues that, for the tested class of mixed workloads on shared commodity infrastructure, these communication roles should be separated architecturally rather than forced through a single protocol. To evaluate that claim, the thesis formalizes an asymmetric control- telemetry pattern and instantiates it in the Asymtra framework using gRPC for synchronous control and …
