To Flea Or Not To Flea: Abiotic And Biotic Factors Driving Flea Parasitism On Wild Deer Mice, Parker Todd, Angela Luis, Mike Kinsella Jan 2026

To Flea Or Not To Flea: Abiotic And Biotic Factors Driving Flea Parasitism On Wild Deer Mice, Parker Todd, Angela Luis, Mike Kinsella

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Deer mice (Peromyscus maniculatus) are an abundant North American rodent and the primary reservoir for Sin Nombre virus (SNV), a hantavirus with a 30-40% case fatality rate in humans. While ectoparasites, such as fleas, are not considered vectors of SNV, their bites may indirectly affect the transmission of SNV by impacting host condition or immune function. These impacts could potentially lead to an increase in host susceptibility and/or an increase in viral shedding, yet there is still little knowledge on what influences flea parasitism on deer mice in western Montana. This study looks to examine how mouse sex, …


Perceptions And Metaperceptions Of Bison In The West, Riley Rush Comstock Jan 2026

Perceptions And Metaperceptions Of Bison In The West, Riley Rush Comstock

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Effective coexistence between wildlife populations and the people that live with them requires an understanding of how people feel toward the species and their management. Bison occupy a unique place in conservation history and management. Once extirpated across nearly all of their range and only recently introduced to areas outside of large tracts of federal land, they are now a jurisdictionally challenged species, with varying management paradigms across a patchwork of landowners and managers. Recent research has shown how activating different social identities can distort people’s attitudes toward species. Here, I explore whether activating urban and rural identities distorts people’s …


The Impact Of A Nf-Κb Signaling Inhibitor On The Antibacterial Activity Immune Response In The Cat Flea (Ctenocephalides Felis), Caroline M. Singer Jan 2026

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 …


Personhood Amidst Process, Bennett B. Gilbert Jan 2026

Personhood Amidst Process, Bennett B. Gilbert

History Faculty Publications and Presentations

Both process philosophy and key forms of philosophical personalism aim to harmonize the flux of reality, especially of organisms, with cosmic values and human meaningfulness. This is because both must face our mortality. This paper makes four suggestions for considering further the connection between these two approaches. First, that process philosophy can supply for personalism a thoroughly reasoned ground for nonreducible complexity. Second, that process thought borrows from personhood its model for cosmic creativity. Third, that both approaches share strong notions of the interdependence of all parts of a relational universe. And fourth, that they differ in respect of moral …


Association Between Caregiver Status And Physical And Mental Health Among National Senior Games Athletes, Chibuzo Uchechukwu Victor Obasi Jan 2026

Association Between Caregiver Status And Physical And Mental Health Among National Senior Games Athletes, Chibuzo Uchechukwu Victor Obasi

Graduate Research Theses & Dissertations

As the population ages, more people rely on informal caregivers, which puts many older adults at risk for health problems. Caregiving can be meaningful and strengthen family bonds, but it often leads to more psychological stress, especially for older adults who also have their own health concerns. Research shows that regular physical activity can help older adults build resilience and improve their mental well-being. Still, we know little about the health of older caregivers who stay very active. This study examines the health effects of caregiving among members of the National Senior Games Association (NSGA), a group of highly active …

Sphingosine-1-Phosphate Regulation To Alleviate Sickle Cell Disease Severity: A Promising Therapeutic Approach, Shahanas Chathoth Jan 2026

Sphingosine-1-Phosphate Regulation To Alleviate Sickle Cell Disease Severity: A Promising Therapeutic Approach, Shahanas Chathoth

Saudi Medical Journal

Abstract Sickle cell disease (SCD) is a genetic disorder that affects millions of individuals worldwide. Chronic anemia, hemolysis and vasculopathy are the most common symptoms that arise from hemoglobin (Hb) polymerization, which is the primary event of SCD. The above process can lead to erythrocyte sickling. Therapeutic options for SCD remain limited, and novel therapies are still being evaluated for their effectiveness in particular populations. Sphingosine-1-phosphate (S1P), a significant bioactive sphingolipid, acts as a potent signal mediator, modulating several cellular functions. The potential role of erythrocyte-S1P in enhancing SCD severity has been previously reported by multiple studies. Therefore, the present …

Digital Emblems In Cyberspace: A Deterrent Or A Target?, Fatemah Albader Jan 2026

Digital Emblems In Cyberspace: A Deterrent Or A Target?, Fatemah Albader

Emory International Law Review Recent Developments

In 2022, the ICRC proposed a digital emblem to identify and protect medical and humanitarian digital assets during armed conflict. While this initiative marks a pivotal evolution of IHL into cyberspace, its effectiveness depends on whether states can ensure accountability, attribution, and compliance. This article argues that digitalizing IHL’s distinctive emblems, such as the red cross, is not optional but mandatory under both conventional and customary law. Once developed, states must adopt and regulate the digital emblem to protect hospital networks and medical personnel online as they are protected offline. However, emblem digitalization alone cannot deter deliberate cyberattacks or unintentional …

Beyond Judicial Intent: The Agency Of The Defense Counsel In Ozawa’S And Thind’S Supreme Court Cases, Bret K. Luchs

Master's Theses or Doctor of Nursing Practice

This thesis seeks to examine how specific legal strategies by the defense counsel in Ozawa v. United States, 260 U.S. 178 (1922), and United States v. Bhagat Singh Thind, 261 U.S. 204 (1923), compelled the Supreme Court of the United States into a reactive and contradictory position. A re-examination of Ozawa and Thind delves deeper into the legal briefs and arguments made by Takao Ozawa and Bhagat Singh Thind, alongside their legal teams. These briefs, opinions of the court, past lower court cases, and personal statements by Ozawa and Thind demonstrate how they did not surrender to the confines of …


Vessel Of Survival, Jonah W. Simmons Jan 2026

Vessel Of Survival, Jonah W. Simmons

Master's Theses or Doctor of Nursing Practice

Survival is not innate or effortless, but learned, regulated, and sustained through continuous labor, both visible and unseen. Vessel of Survival is an exploration of the human body as a site of containment, adaptation, and endurance shaped by trauma, systemic pressure, and the conditions of contemporary life. Through ceramic form, ruptured surfaces, photographic imagery and narrative intervention, this work explores how trauma, chronic illness, and socioeconomic systems inscribe themselves onto the body. Within this framework, the body becomes a vessel that continually negotiates fragility and resilience.

This investigation is informed by my diagnosis with Type 1 diabetes, a condition that …


New Hampshire Shellfish Under Pressure: Physiological Effects Of Climate Change And Toxic Algal Blooms, Olivia Boyan Jan 2026

New Hampshire Shellfish Under Pressure: Physiological Effects Of Climate Change And Toxic Algal Blooms, Olivia Boyan

UNH URC Open (2026 and after)

Climate change driven effects on the ocean, including warming water, acidification, and changes in the presence of harmful algal blooms (HABs) are causing metabolic pressures on marine organisms, particularly in the Gulf of Maine. Shellfish are susceptible to these pressures because their metabolic processes including growth and respiration are influenced by water temperature, pH, and consumption of algal toxins. This study investigates the effects of ocean warming, acidification, and diet toxicity level on the growth and respiration of Blue mussels (Mytilus edulis), Eastern oysters (Crassostrea virginica), and Sea scallops (Placopecten magellanicus). Selected individuals were subjected to water treatments simulating ambient …

Role Of Mkp-2 In Pancreatic Beta Cell Function & Development Of Diabetes, Nabin Ghimire Jan 2026

Role Of Mkp-2 In Pancreatic Beta Cell Function & Development Of Diabetes, Nabin Ghimire

Dissertations

Diabetes mellitus is a chronic metabolic disease characterized by persistent hyperglycemia. Type 1 diabetes results from autoimmune destruction of β-cells, whereas Type 2 diabetes is associated with obesity and insulin resistance. Type 2 diabetes (T2D) and metabolic-associated fatty liver disease (MAFLD) are closely linked, as individuals with T2D are twice as likely to develop MAFLD. Previous work from our lab demonstrated that overexpression of MKP-2 in obesity promotes hepatic steatosis, diet-induced obesity, reduced insulin sensitivity, and increased body weight. However, the role of MKP-2 in the onset and progression of diabetes remains unclear. The objectives of this study were to …


Regulation Creations: A Trauma-Informed Resource Addressing Sensory And Socio-Emotional Childhood Challenges, Meagan Noel Barnes Pearson Jan 2026

Regulation Creations: A Trauma-Informed Resource Addressing Sensory And Socio-Emotional Childhood Challenges, Meagan Noel Barnes Pearson

Occupational Therapy Capstones

Introduction: Trauma is ubiquitous and can negatively impact many life outcomes. Though trauma can occur across the lifespan, particular emphasis has been placed on the outcomes of experiences that occur in childhood. Adverse childhood experiences (ACEs), as coined by Felitti et al. (1998), pertain to traumatic events that occur before the age of 18, and the correlation between the number of ACEs and poor health outcomes is significant. Children can begin demonstrating unfavorable symptoms upon becoming exposed to trauma. Current literature has illustrated particular differences in sensory systems and social skills for young children. These challenges can lead to hardship …


Covering The Care: Why Financial Resources Matter For Health, Mark Bonica, Phd,Mba,Ms Jan 2026

Covering The Care: Why Financial Resources Matter For Health, Mark Bonica, Phd,Mba,Ms

All Materials

Where people end up in the income and wealth distribution has a powerful and lasting influence on how healthy they are and how long they live. This is not just a story about poverty versus comfort. Across the entire population, health improves step by step as financial resources increase. Researchers call this pattern the health gradient.

This brief explains why that gradient exists. Drawing on decades of research from economics, public health, and social epidemiology, it shows how limited financial resources shape health through multiple pathways that unfold over different time horizons—from immediate consequences to cumulative effects that build …

Climate Change Effects On Biomass And Greenhouse Gas Emissions Are Ameliorated By Nontoxic Endophytes In Southeastern Usa Transition Zone Tall Fescue Pastures, Rebecca Kay Mcgrail, Jonathan D. Moore, A. Elizabeth Carlisle, Jim A. Nelson, Rebecca L. Mcculley

Plant and Soil Sciences Faculty Publications

Background: The plant–microbe interaction between tall fescue and its endophyte Epichloë coenophiala can affect ecosystem responses to changing rainfall patterns and increasing temperatures. Endophyte-infected (E+) stands often exhibit improved stress tolerance and differing soil greenhouse gas (GHG) emissions compared to endophyte-free (E−) stands. However, it is unknown if mammalian nontoxic endophyte (NTE) strains introduced into some tall fescue cultivars confer differing stress tolerances or reduce soil GHG emissions.

Methods: We quantified the impact of fescue-NTE symbioses in Jesup and Texoma on biomass and GHG emissions in response to increased temperature (+3°C) and altered precipitation (50% lengthened interval between events) using …


Dosage Sensitivity And The Evolution Of Dosage Compensation: Tests Of The Insensitive Sex Chromosome Hypothesis In Flour Beetles, Shana Pau Jan 2026

Dosage Sensitivity And The Evolution Of Dosage Compensation: Tests Of The Insensitive Sex Chromosome Hypothesis In Flour Beetles, Shana Pau

Biology Dissertations

Sex chromosome evolution generates imbalances in gene dosage that can disrupt gene expression and organismal function. These imbalances are often resolved through dosage compensation mechanisms, yet the factors that drive the emergence and diversity of these systems remain poorly understood. This dissertation addresses a central question in evolutionary genomics: what governs the evolution of dosage compensation?

Focusing on dosage sensitivity as a potential driver, I evaluate the Insensitive Sex Chromosome Hypothesis (ISCH), which predicts that chromosome-wide compensation is more likely to evolve in genomic contexts that are not depleted of dosage-sensitive genes. Using flour beetles (Tribolium spp.) as a …


Coordinating The Layers: Regulation Of Peptidoglycan Synthesis And Cell Wall Assembly In Mycobacterium Smegmatis By Murj And Pgfa, Karen Emmanuella Samaga-De-Tembiwa Jan 2026

Coordinating The Layers: Regulation Of Peptidoglycan Synthesis And Cell Wall Assembly In Mycobacterium Smegmatis By Murj And Pgfa, Karen Emmanuella Samaga-De-Tembiwa

Biology Dissertations

The mycobacterial cell envelope consists of three covalently linked layers whose synthesis must be coordinated to maintain structural integrity during polar growth. While the biosynthetic enzymes for each layer are well characterized, the molecular mechanisms that coordinate synthesis across layers have remained poorly understood. This thesis investigates two essential transmembrane proteins, PgfA and MurJ, that regulate peptidoglycan metabolism in Mycobacterium smegmatis and provide new insight into how mycobacteria synchronize cell wall assembly.

We present evidence that PgfA functions as a bifunctional regulator that links peptidoglycan metabolism to the availability of trehalose monomycolate (TMM), a key mycolic acid precursor. Through epistasis …
