Visualizing Ozone Pollution In The Denver Metro Area Using A Bioindicator Garden, Ella K. Mathews, Hillary Hamann, Julie Morris, Erica L. Larson

DU Undergraduate Research Journal Archive

Since the industrial revolution, widespread fossil fuel combustion has significantly increased atmospheric pollution. The combustion of fossil fuels releases nitrogen oxides (NOx) and volatile organic compounds (VOCs), which form tropospheric (ground-level) ozone when exposed to sunlight. Ozone directly harms plants by disrupting their ability to absorb carbon dioxide, release oxygen, and carry out photosynthesis. Bioindicator species are plants that have visible responses to environmental conditions, such as ozone, and can act as “canaries in the coal mine,” indicating the health of their environment. In this study, we used a garden of ozone bioindicator species (ozone garden) as a cost-effective tool …

King Of The Jungle: Comparative Analysis Of The Geopolitical Narratives Surrounding Fordlandia And A Proposed Resort Park In El Mirador, Rachel Jaeger

DU Undergraduate Research Journal Archive

Environmental geopolitics is a field of study in which narratives about the environment are analyzed to reveal the underlying motivations and objectives they support. Using Shannon O’Lear’s (2020) framework of environmental geopolitics, I conduct a comparative analysis of the narratives surrounding two distinct development projects: Henry Ford’s historical company town in the Brazilian Amazon, Fordlandia, and a proposed ecotourism resort park in El Mirador, Guatemala. Analysis of Fordlandia reveals a narrative of American frontierism and a man-versus-nature perspective that served to paint the environment as belligerent and thereby justify corporate control and Indigenous assimilation. Narratives surrounding El Mirador differ, representing …

Direct Democracy In The Twenty-First Century: Massachusetts Open Town Meeting And Citizen Participation, Daniel W. Santos

Graduate Doctoral Dissertations

Town Meeting is a unique system of democratic governance that can be found only in New England towns, where it has been the primary form of local government for nearly four centuries. Town Meeting is a type of direct democracy where laws, policy, and decisions are made by a plurality of a town’s eligible voters acting as its legislative body. There is limited scholarship addressing Town Meeting, with much of the extant literature focusing on the benefits of the direct democracy aspect of this form of government. Town Meeting has been generally known to be poorly attended by citizens. The …

Symmetry And Psychosocial Adaptation To Trauma, Illness And Disability Part I: Views From Physics, Medicine And Psychology, Hanoch Livneh

Leadership, Learning and Counseling Faculty Publications and Presentations

The aim of this two-part paper is to discuss the concept of symmetry and its derivatives, symmetry breaking and asymmetry, and the role they assume in elucidating the structure and processes that underlie psychosocial adaptation to traumatic experiences. To achieve this aim, in Part I, first, a cursory review of symmetry is undertaken as it applies to physics, including conservation laws, the forces of nature, and leading theories of nature. Second, the paper addresses how symmetry is perceived in biology and medicine, including symmetry within biochemical and genetic structures, the human body, and the onset of disease processes. Third, the …

Khirbat Khuwweikha (Kafr Kanna): Hiding Complexes From The Roman And Early Byzantine Periods In The Jewish Galilee, Yinon Shivtiel, Dror Barshad, Dina Avshalom-Gorni, Nili Ahipaz, Ruthy Lewis-Bloom, Yonatan Adler, Ram Bouchnick, Yarden Pagelson, Uri Berger

Qadum: Journal of Excavation Reports from Israel

Decades of research on Roman-period hiding complexes in the Galilee have identified 85 such complexes to date. Like the hiding complexes found in Judea, they were used as places of refuge during periods of distress under Roman rule in the country. Extensive archaeological excavations conducted in the hiding complex at Khirbat Khuwweikha, near Kafr Kanna and northwest of Nazareth, have yielded impressive finds, including pottery, glassware, metal items, coins, an ostracon and bones. Such a large quantity of diagnostic finds is rare in Galilean hiding complexes, and the assemblage attests to the use of the complex by Jews during three …

The Feather Of The Quill: How Folklore Shapes Human Relationships With Wildlife, Taylor Breeanne Nelson

Master's Theses

This thesis examines how folklore and cultural phenomena shape human relationships with wildlife, arguing that the stories a society tells about animals are not merely reflective of its values but are constitutive of them. Drawing on narrative research methods sourced from literature and academic journals and interviews with academics, conservationists, and community members, this project examines the role of animal folklore.

I discuss how narratives around wildlife evolved alongside the development of the United States, arguing that the beginnings of mainstream American conservation not only displaced existing communities but also erased the sophisticated human-animal relationships their traditions had long sustained. …

Improving Human-Wildlife Coexistence: An Ecological And Educational Approach To Rewilding Grizzly Bears (Ursus Arctos Horribilis) In California, Amanda C. D. Rosales

Master's Projects and Capstones

Megafauna extinction during the Holocene has been both caused and amplified by climatic changes and human influence. By the last half century, large carnivores were diminished in Europe and the United States, but policies increasingly addressed species decline and their territories expanded. This research examined large carnivore rewilding across the European Union and United States, specifically for rewilding brown bears, Ursus arctos, in historic habitat. Next, case studies for the health status of climate-impacted whitebark pine, Pinus albicaulis, a high energy food for bears, was assessed. Ultimately, research case studies, human perspective surveys, and the California Department of Education content …

Linking Fishery Productivity To Child Health In The Coastal Tropics, Francisco Flores-Mejia

Master's Theses

Fish are a primary source of calories, macronutrients, and income for coastal communities around the world, but overfishing and environmental changes have dramatically reduced productivity in the majority of small-scale fisheries. The social costs of these losses are believed to be large, particularly in poorer communities, but most estimates of fishery productivity effects on households are contextual and difficult to generalize. We combine a remote sensing measure of pelagic fishery productivity with geolocated child health and growth data from 34 countries in the coastal tropics. We estimate that the difference between sustainedly good versus bad fishing conditions corresponds up to …

Kicau Kericau: The Chirps And Warbles Of A Bird-Human Story, Airien Ludin

Masters Theses

This thesis tells the tale of bird-human relationships and what it means to live alongside one another, subverting the hierarchical view of humans as above birds inherited from colonial history. It asks how the practice of illustration can function as a site of Two-Eyed Seeing, where scientific and local knowledge are held together as an entangled narrative. It also examines how mendongeng (storytelling), as I have experienced it within Indonesian culture and everyday contexts, can help us understand birds as a companion species with their own agency.

This project takes two forms: first, a picture book titled Sun Bird …

Tùn-Scene And A-Futurism: Biomythography, Opacity, And Posthuman Imagination, Minglu Du

Masters Theses

Grounded in the author’s position as a Chinese feminist, this thesis examines how East Asian women, as well as East Asian-coded femininity more broadly, are objectified and othered within futurist visual culture in the age of artificial intelligence. Through an engagement with ornamentalism, techno-Orientalism, and posthumanism1 , it argues that the persistent figure of the feminized humanoid cyborg continues to reproduce colonial and patriarchal structures of desire, rendering marginalized bodies as fetishized and violable surfaces. In response, the thesis develops Tùn-Scene, a biomythographic artistic framework and the first experiment in what the author provisionally names A-Futurism. Drawing on Donna Haraway’s …

I Miss My Computer: Online Artistry, Web Aesthetics, And Coming-Of-Age In A Digital Landscape, Catherine Capeci

Masters Theses

This thesis explores how young artists develop their creative practices in a world informed by digitality. Through survey research of 44 art students between the ages of 14 and 22, as well as a process of autoethnographic inquiry, I examine how artists in high school and college relate to digital imagery, web archives, online gaming, and social media platforms, and how these experiences inform artmaking. I believe that art educators should explore how the internet informs aesthetic and conceptual sensibilities, and how these sensibilities show up in young artists’ work, more so than focus on digital media as its own …

Numb., Anna Rapson

Masters Theses

Social media platforms, from their conception, posed a break in the lived experience of the average human being’s day to day routines. Although access to information has always been shaped by portals into other lived realities—through photojournalism, print legacy media, news broadcasts both on radio and television—social media has posited a novel phenomenological architecture where borders between embodied reality and perception of lived experience are simultaneously blurred and reinforced. This morphed duality of consciousness positions the body and mind in tension, deconstructing pre-social media conceptions of the ontology of lived experience. In a digital world shaped by limitless input by …

Finding A Way Out Of The Filter Bubble: The Confusion Of A Heavy Social Media User, Longwen Miao

Masters Theses

This thesis studies how algorithmic recommendation systems reshape visual perception, aesthetic judgment, and the construction of selfhood within contemporary digital culture.

Everything begins with the experience of repeatedly encountering algorithmically recommended content on everyday digital platforms. On these platforms, images, sounds, and social interactions are continuously selected, repeated, and reorganized by predictive systems, forming an environment in which perception is constantly structured and adjusted.

From this observation, the research raises two central questions: how do algorithmic recommendation systems reshape visual perception, aesthetic judgment, and self-recognition, and how might these systems be intervened in or made perceptible through artistic practice? Within …

Domestic Travelers: Transparent Machines, Hollow Bodies, Hanyi Wang

Masters Theses

Digitization is not a modern invention. Derived from the concept of fingers, this mindset of packing information into quantifiable, interchangeable units sounds mechanical, yet eerily physical. Try to imagine: a ghostly hand with millions of fingers with the same length, likeness, and function. Under the worldview of Digital Narrative, we live in a digital simulation: everything is representable with quantifiable units, fluid across media. Yet under this spectacle of convenient abundance, something is missing. The Unknowables are replaced with arbitrary symbols, while the Uncategorizables are omitted. This is a framework that cannot accommodate human subtleties and complexities. One needs to …

Until The Ground Breaks, Annie Hu

Masters Theses

Until the Ground Breaks explores the complex relationship between personal memory, embodied experience, and internalized "archival logic." By examining long-term cross-cultural diasporic experiences and the shifting dynamics of family narratives—including the sensory experiences and fading memory of a grandmother, a father's correspondence that acts as a textual record of emotional logic, and the continuous revision of family history—this thesis dissects the psychological tremors that occur when the illusion of a singular, stable memory archive collapses. This research rejects the view of memory as a static container of truth, revealing it instead as a dynamic, unstable, and constantly rewritten living system. …

41.82379°N, 71.38497°W, Xiaotong Cai

Masters Theses

I, Xiaotong Cai, have known an abandoned bridge was lifted and stuck at 64-degree from 1976. I have walked and bent down towards it for over 60 times, each paralleling a journal entry. The visits and 27,351 words (up until May 5th) are the living proof: observation, encounters, correspondence, collectively and personally. It’s been nine months since it emerged in flux. Two flesh. A moving outsider and a still bridge. How can an Unused giant activate a human body? Who is the attractor and intervener?

Here, my solution is to conduct a series of small gestures. I say, interpreting without …

Care Ecologies Between Knots, Eliza R. Marris

Masters Theses

Discarded fibers like raw wool behave the way harm reduction does. Harm reduction resists stigma and works to move beyond assumptions and oversimplifications of substance use and addiction. Wool is irregular, complicated, and emotionally charged. It resists compression and maintains its own being even when pulled apart. Working with raw wool is in relationship with complexity, as is harm reduction.

At its core, harm reduction is grounded in thoughtfulness and empathy towards people, their lived experience, and its nuances. It is a witness to lives, memories, and imprints, acknowledging the entangled realities of addiction. Our detachment from fiber remainders, materials …

Draw To Breathe, Ranran Ma

Masters Theses

This thesis explores visual expression in drawing as an intuitive mode of thinking suited to everyday life—a form of expression that runs parallel to language and surpasses it.

The project begins with a daily Post-it note drawing practice. These drawings often emerge before conscious understanding, subsequently accompanied by brief text, allowing image and word to resonate through emotion and intuition. Through the use of small-scale, portable, low-pressure materials, and with immediacy and intuitive freedom as the foundation of making, a visual language system grounded in the self develops. Through this sustained practice, I developed an instruction-based card system titled Draw …

Reading Exercise (You Are The Hero): Dedicated To The Providence River Under The Mall, 02.17.2026, Deborah Fischer

Masters Theses

This play uses the performative potential of guilt, forgiveness, and self-help techniques as a catalyst for a new dynamic, one in which the pursuit of a false narrative, along with the structures it generates, becomes more real than reality itself. It employs “bad acting” and the practice of cold reading to stage a series of acts that function as an entry point into one’s own psyche, leveraging the peripheral space around familiar actions to allow chance, free will, and the experience of “real time” to temporarily come into effect. PLAYER 1: The bad actor is the most utopian one. CLOWN: …

Weaving Grounds: Connecting Canyons And Empowering Borderland Communities, Maria D. Lopez Vazquez

Masters Theses

National policies materialize in the United States-Mexico political divide, also known as the borderlands. Willow Canyon is a dissected land form inextricably linked to the Tijuana River watershed, forming with the adjacent landforms on both sides of the border one landscape. The Guadalupe Hidalgo Treaty¹, signed in 1848 by the US and Mexican governments, traced an arbitrary line across these landscapes, disregarding their relationship. The consequences of these actions are visible in the physical deterioration of the landscape and ecology, as the hydrological cycle has been modified. In the 1940’s, the picturesque flow of Willow Canyon was dissected by urbanization, …

Generative Ai And Student Engagement, Motivation, And Learning: Exploring The Use Of Generative Ai In Higher Education Online Courses, Jeffrey L. Simmons

Dissertations

ABSTRACT

The rapid emergence of Generative AI (GenAI) large language models (LLMs) such as ChatGPT in higher education has left many institutions unprepared to assess their potential benefits and risks. This mixed-methods study examined how ChatGPT and Google’s NotebookLM were integrated into online course development and delivery at a small private nonprofit university in California, and assessed their perceived impact on student engagement, motivation, and learning.

Data were collected from post-course Likert-scale surveys completed by students across three online master’s-level courses and from pre-course prediction surveys by instructors in the two NotebookLM courses. Quantitative analyses included one-sample t-tests against a …

Burning Out: A Narrative Exploration Of The Adaptive Challenge And Scaffolds Built Toward Sustenance Among Immigrant Rights Activists In San Diego County, Anna C. Runion

Dissertations

Activist burnout has been identified as one of the greatest threats to social movement sustainability, and the lived experience of paid immigrant rights activists remains undertheorized. This narrative inquiry explored activist burnout among 10 San Diego County immigrant rights activists, revealing how this community understands burnout, what factors contribute to its production, and how activists sustain themselves within it. Using Clandinin and Connelly’s (2000) narrative inquiry methodology, the researcher conducted in-depth individual interviews with ten activists representing a range of intersectional identities and roles. Narrative profiles were analyzed through holistic narrative reading, narrative reporting, structural and emergent coding, and cross-narrative …

Tuning The Neighborhood: Purifying People, Places, And Environments In Suburban Kolkata, Sourav Saha

Yale Journal of Music & Religion

In modern science, disciplines such as physics, mechanical and civil engineering, seismology, and acoustics have conceptualized vibration as a quantifiable mechanical phenomenon, measured through the metrics of frequency, amplitude, and resonance. In contrast, scholarship in anthropology, musicology, and sound studies has approached vibration as a socio-historical, cultural, and political phenomenon. This article examines how vibration (spandan) operates as a metaphysical, sensory, and ethico-affective force that mediates relations among people, places, and environments. Focusing on the practice of satsang adhibesan (devotional congregation), the article demonstrates how members of the Deoghar-Satsang community participate in sonic rituals of prayer, silent chanting, meditation, sacred …

Environmental Mercury Alters Immune Pathways Linked To Autoimmune Risk In Mice Mirroring Humans, Maurgan Lee, Paul Stemmer, Randall Gill, Allen Rosenspire, Anil Aranha, Heather Gibson

Medical Student Research Symposium

Background and Purpose: Mercury is a pervasive environmental contaminant, and human epidemiologic studies have linked chronic low-level exposure to increased autoimmune disease-risk. Dysregulated lymphocyte activation and impaired signaling tolerance are central mechanisms in human autoimmunity. Protein phosphorylation governs lymphocyte differentiation and function, alterations in phosphoproteomic networks may represent a signature of immune disruption. This study evaluates how low dose mercury exposure modifies B and T cell abundance and intracellular signaling patterns in BALB/c and Diversity Outbred (DO) mice.

Methods: BALB/c and DO mice were exposed to low dose HgCl2 in their water for two weeks or provided standard water controls. …

Refuting Ruscism: A Critique From Biblical Social Ontology, Paul Miles

Doctoral Dissertations and Projects

This dissertation argues that the ideology of Ruscism is incompatible with biblical Christianity on the basis of God’s design for the individual, the family, and the country. Indeed, the extent of incompatibility between these two worldviews renders any attempt to syncretize them a significant departure from biblical Christianity. God’s design for society is an absolute standard by which political ideologies may be evaluated, and these three societal units will suffice to demonstrate that Christians must reject Ruscism.

This dissertation will describe these three societal units—the individual, the family, and the country—as they are described in biblical Christianity and contrast their …

A Qualitative Case Study Of Equine Assisted Services At Healing Strides Facility, Erica Lynn Gray

Doctoral Dissertations and Projects

The purpose of this qualitative case study is to portray how a well-run facility conducting equine assisted services works from an intra-organizational perspective. It is a bounded qualitative case study that focuses on the equine assisted services provided, the program and services designed and the rationale for choosing those programs, how services are operationalized and facilitated by practitioners, how equine welfare is considered, and the experiences and perspectives of those participating in the organization, development, or facilitation of equine assisted services at Healing Strides. This study uses Robert K. Yin’s theory driven methodological approach to qualitative case studies that focuses …
