There Would Be Food Forever: Leveraging The Culvert Case To Fight Toxic Fish Contamination In The Columbia River, Sarah Van Voorhis

UC Law Environmental Journal

The Native American Tribes of the Pacific Northwest signed treaties in the 1800s with a representative of the federal government that purported to protect their right to fish in their usual and accustomed places. Despite this explicit pro-vision of their treaties, the Tribes have struggled to exercise this right to fish. Through a series of court cases spanning decades, culminating in The Culvert Case in 2017, the Stevens Treaty Tribes have secured their right to access their tradi-tional fishing grounds, their right to an equal share of the harvestable fish, and finally, their right to the continued existence of the …

Texas-Sized Tremors: A Call For A Seismic Shake Up To Recourse For Induced Seismicity, Michael Mcroy

UC Law Environmental Journal

In the last twenty years, seismicity in Texas has reached unprecedented levels, surpassing even those in California. Experts have theorized that oil and gas operations, specifically wastewater removal, are the leading cause of this seismic uptick. While scientists and the state continue to refine their understanding regarding the links to oil and gas operations and increased seismicity across the state, the unfortunate reality is that many homeowners are facing the damage from increased seismicity alone.

Currently homeowners find themselves in a legal and financial quagmire: private earthquake insurance is unjustifiably expensive, riddled with exclusions, and accompanied by an unsophisticated claims …

The Effects Of Incubation Humidity On Broiler Chicks, Claire Caples

Animal Science Undergraduate Honors Theses

Leg health issues are a welfare problem in commercial broiler chickens and an economic issue for the broiler industry. Broilers exhibiting leg abnormalities show altered gait, reduced ability to access resources, and increased lameness incidence. These leg health issues can result from many animal and environmental factors during incubation and post-hatch. Incubation strategies may contribute to the development of leg health issues, and recent research has increased focus on incubation factors affecting embryonic development and health and welfare post-hatch. Thus, the objective of this study was to evaluate the effect of high (80%), low (55%), and ideal (65%) humidity on …

Developing Protective Measures To Reduce The Incidence Of Bacterial-Induced Chondronecrosis With Osteomyelitis In Broiler Chickens, Alexa L. Thomas

Animal Science Undergraduate Honors Theses

Bacterial Chondronecrosis with Osteomyelitis (BCO) lameness is a significant animal welfare and food safety issue affecting the commercial broiler industry in the United States and worldwide. Bacteria can translocate from the respiratory system and/or the gastrointestinal tract into the bloodstream, eventually settling in bone microfractures leading to necrosis and BCO lameness.

This study evaluated the effects of Probiotic 1 and Probiotic 2 on the incidence of BCO lameness in broiler chickens. Probiotic 1 was applied as a spray on Day 1-old chicks, while Probiotic 2 was administered prophylactically (orally in feed) from Day 1 to Day 56. Birds were assigned …

The Utilization And Deterioration Of Travertine In Classical, Baroque, And Fascist Architecture: A Case Study From Rome, Italy, Kaitlyn V. Fitzgerald

Graduate Theses and Dissertations

Travertine limestone has formed the resilient backbone of Roman architecture for over two millennia and across several cultural periods. This study identified the leading causes of travertine decay in Rome across Ancient, Baroque, and Fascist periods in order to efficiently prioritize conservation and restoration efforts across the city. The methodology developed here can then be utilized in other urban settings. Rome’s iconic landmarks such as the Flavian Amphitheater, St. Peter’s Basilica, and the Spanish Steps all owe their existence to this local limestone.

Quantifying The Role Of Climate On Tropical River Flow (Guarare River) Along The Panama Pacific Coast, 1981 – 2020., Jessie Abrego - Bonilla

Graduate Theses and Dissertations

The Guarare River watershed on the Azuero Peninsula of Panama, part of the Panamanian Dry Arc, experiences significant hydrological variability driven by seasonal changes, elevation, and the El Niño/Southern Oscillation (ENSO). This study investigates precipitation and river discharge patterns over 40 years (1981 – 2020), showing that elevation influences rainfall distribution, with higher-altitude areas receiving more precipitation during the Neutral and El Niño phases. In contrast, La Niña phases bring increased rainfall to lower-elevation areas, such as Pocrí. Seasonal ENSO effects reveal that El Niño phases reduce dry-season precipitation, lowering river discharge. La Niña events sustain high wet-season rainfall, peaking …

An Analytical Evaluation Of Economic Geography Within Maine And Its Resource Industries: 1600 To Present, Maureen Mantooth

Graduate Theses and Dissertations

Resource peripheries represent a fringe area within economic geography, originating from the core-periphery theory developed by Friedmann and Miller. This concept has evolved to address global and regional contexts, referring to marginalized regions that rely heavily on the extraction and export of natural resources. By studying these regions, we gain a deeper understanding of critical components in global economic systems. This dissertation focuses on Maine as a case study of a resource periphery, using the framework proposed by Hayter et al. (2003) within the broader regional contexts of New England and the United States. Key factors explored include resource exploitation, …

Mindful Symbiotic Ecosystems. Designing For Women In Remote Workspaces, Andrea Guevara Araujo

Graduate Theses and Dissertations

Women represent 61% of designers in the workforce but hold only 29% of leadership roles. This disparity highlights a critical need for an ecosystem that removes barriers and cultivates mentorship, community, and leadership among women (Bolt, 2020). Even though women have proven their ability to succeed in male-dominated corporate cultures, the real question is not about capability but sustainability. Driven by overwork, competition, and burnout, the workplace does not just push women out; it leads to long-term instability for the entire organization (Krivkovich et al., 2024). In the workplace, a culture of masculinity reinforces harmful, outdated mindsets and glorifies aggressive, …

Designing For Autonomy: Enhancing The Autonomy Of Young Women With Postural Orthostatic Tachycardia Syndrome (Pots) Through Interactive Narrative, Jessica Gobble

Graduate Theses and Dissertations

Postural Orthostatic Tachycardia Syndrome (POTS) is an autonomic nervous system disorder with multisystem impacts. Classified as a chronic illness and oftentimes triggered by viral infections, incidents of POTS have become increasingly common following the outbreak of COVID-19. Primarily affecting young women ages 18 to 30, POTS disrupts an individual's health during their transition to adulthood. This issue is further complicated by medical gender bias, latent care, and misdiagnosis, which leave this demographic vulnerable within traditional healthcare systems (Shaw et al., 2019). As traditional healthcare systems primarily address acute rather than chronic conditions, interactions with these systems are intermittent. Consequently, individuals …

Public Comment: Using Critique-Like Mediating Artifacts To Democratize Discourse At City Council Meetings, Piper Schuerman

Graduate Theses and Dissertations

Are local governments designed for equitable citizen participation? While civic engagement aims to empower citizens and support representative governance, barriers to participation can hinder those outcomes. City council meetings, key venues for public input, pose specific challenges such as long durations, dense content, and intimidating formalities. These issues disproportionately affect Generation Z (born between 1997 and 2012), who frequently report feeling underinformed or having limited time to engage. This thesis explores how city council meetings might use multimodal mediating artifacts, inspired by design critique practices, to make public discourse more accessible for Gen Z adults.

Development And Investigation Of A Novel Near-Wall Methodology For Large-Eddy Simulation Based On Dynamic Hybrid Rans-Les, Michael Tullis

Graduate Theses and Dissertations

The use of computational fluid dynamics (CFD) to test engineering designs with reduced cost and time compared to physical testing has become increasingly common in a range of industries and research fields. While numerical methods exist that can accurately solve the equations that govern the flow of fluids, these methods are computationally expensive for practical engineering problems due to the large amount of computational power needed to resolve the fluid flow over the entire range of length and time scales. Several different approaches have been introduced to address this computational cost issue, namely Reynolds-averaged Navier-Stokes (RANS) modeling and scale resolving …

A Living House Never Stands Still, Holly Rose Kranker

Graduate Theses and Dissertations

A Living House Never Stands Still is an exhibition that explores the interplay between place, memory, and the suspension of time through diverse mediums and materials. I engage with seemingly mundane objects, interpreting them through a non-linear, dream-like, and irrational framework to unearth latent connections across time–past, present, and future. Central to these explorations is the concept of home—not merely as a physical location, but as an evolving entity. Home is a sacred space for me.

My recent studio reflections are focused on the lifecycle of objects, the emotional responses they evoke, and how these cycles emulate the human body …

Graduate Theses and Dissertations

Big Blue is a record keeping system of sorts- to show the story of my relationship with the tallgrass Big Bluestem as an Oglala Lakota tribal citizen of The Sioux Nation. It’s meant to question the idea of binaries, what is valued, how verticality is only powerful if supported horizontally, and the legacy of the remnants that remain. Big Bluestem is a reminder of our linked survival as humans with the land and the importance of knowing the individual names of the leafy and legged beings who exist equally on it.

Adult Effects And Affects: Dialogic Reflections And Theoretical Analysis Of Systemic Led Education, Early Childhood Education, And Art Education, Katherine Galaz

Graduate Theses and Dissertations

Through self-exploration, reflexive dialogue, and literature review I look to the grey areas, contradictions, and margins of hegemonic educational practices. I highlight the ways in which the standard of education is structured in opposition to how children seek to understand and make sense of the world. In my analysis of early childhood settings and art education under the umbrella of the U.S. education system, I approach historical antecedents involving colonialism and systemic injustice. Within the field of art education, I specifically look at the artistic and imaginative ways that children resist societal norms in early childhood education. As such, I …

Navigating The Double Jeopardy: The Intersectional Experiences Affecting Black Menopausal Women In The Workplace, Genena Woodson Armstrong

Women’s Leadership

Nearly half of the population of the United States will experience menopause at some point in their life. The topic of menopause is often silenced, especially in professional corporate settings. Particularly for Black women, who are already marginalized, research has shown that menopause symptoms are more severe and last longer than white women. This thesis explores the intersectional experiences of Black women in America as they navigate menopause in the workplace, a topic that has remained largely overlooked due to the lack of workplace diversity, health discourse, and disparity. The following research study employs a mixed-methods approach, incorporating surveys and …

Low-Field Magnetoresistance In Nanocomposites Of La₀.₇Sr₀.₃Mno₃ And Metal Oxides, Nicholas K. Thiel-Hudson

University Scholar Projects

Pure La_0.7Sr_0.3MnO₃ (LSMO) exhibits colossal magnetoresistance (CMR) with large applied magnetic field over a narrow temperature range (intrinsic behavior), limiting its application to narrow temperature ranges. In contrast, the extrinsic CMR effect originates from inhomogeneities at larger length scales, such as grain boundaries and phase separation, where the structural features act as tunneling barriers, leading to a low-field magnetoresistance (LFMR) response, thereby expanding the application of LSMO into the low-field regime over a broader temperature range. In this work, the magnetotransport behavior of pure LSMO thin film is compared to the composite layered heterostructures of …
