This management guide is intended to provide stakeholders with a summary of new and existing knowledge on integrated Poa annua management. Here we review the basic biology and ecology, as well as practical integrated weed management (IWM) strategies developed for its control.

Integrating Methods To Investigate Phytoplankton Dynamics Along Gradients Of A Major Urban River, Nicholas Sheldon

University Honors Theses

Waterways that support human society and life on Earth host superabundant microorganisms which support all ecosystems and food webs: phytoplankton. This study aimed to identify and quantify phytoplankton in the Willamette River in order to understand the dynamics between different phyla. Building on previous studies, which showed that communities of phytoplankton change with the river environment, this work determined how eukaryotic and prokaryotic phytoplankton vary with one another while inhabiting the same river conditions. The approach involved sampling the Willamette river over a weekly time series and combined analytical techniques of qPCR, flow cytometry, and image cytometry to assess population …

Why Democracy Has Lost The Trust Of Modern People In The Modern Era, Erica Rubel

University Honors Theses

This thesis examines the growing crisis of democratic legitimacy among young people in the 21st century. Across the United States and globally, young people are increasingly disillusioned with formal democratic systems, not because they are disengaged or apathetic, but because they feel systematically excluded from structures that claim to represent them. Through an interdisciplinary framework rooted in political theory, affect studies, intersectionality, and critical media analysis, this research argues that democratic trust cannot be repaired without emotional truth, structural accountability, and reimagined participation.

Drawing on the work of Lipset (1959), Crenshaw (1989), Cohen (2020), Papacharissi (2015), and Spade (2020), this …

An Erotics Manifesto: Developing Critical Feminist Theory Through Erotic Fiction, Cairn Des Lions

University Honors Theses

Erotic literature provides a unique lens through which feminists can develop theory because it reveals the natures of our gendered relations in the contexts of our desires. By either writing or critically reading erotic literature, feminists can explore questions about what and why we desire, how we act upon our desires, and what our desires and actions reveal about our relationships to each other. This thesis uses feminist theory to analyze the potential of fiction focused on eroticism to aid in rethinking gender and sexuality norms.

Investigating A Link Between Dna Repair And Dna Replication In Escherichia Coli Using A Bacterial Two-Hybrid System, Lo Cooper

University Honors Theses

Cells rely on nucleotide excision repair (NER) to remove bulky DNA lesions, such as those caused by UV light. In Escherichia coli, NER involves the UvrABC complex, and includes two main pathways, global genomic repair and transcription-coupled repair (TCR). While TCR, which preferentially removes lesions that block RNA polymerase on the transcribed strand of active genes, is well studied, less is known about whether a similar coupling between repair proteins and replisomes blocked by damaged DNA exists. Such a process has been suggested by a high throughput interactome study, using the replisome subunit HolC as bait and the damage …

Indigenous Science And The Legacy Of Fire: Resilience, Fuels, Mosaics, And Eco-Cultural Landscapes In Oregon’S Coastal And Cascade Range, Julia Alcalá

University Honors Theses

Most of Oregon's western Cascade and Coastal range is a landscape that has historically been considered devoid of mid to low-intensity fires by Western science. However, for time immemorial, Indigenous peoples have been stewarding the forests through the use of "good fire," creating diverse and heterogenous landscapes with mixed fire regimes, ranging from less than a decade to several centuries since the last fire, resulting in a mosaic of patchy forest, oak savannas, prairies, and wetlands. Yet centuries of Indigenous displacement, cultural assimilation, and suppression of cultural burning contributed to this prevailing belief. Despite that, in recent decades, Western scientists …

Is Sharing Always Caring: Critical Discourse Analysis On The Parasociality Of Family Influencing Content On Tiktok, Riley Brown

University Honors Theses

Sharenting, the practice of parents sharing images and information about their children on social media, is a growing, cross-platform phenomenon threatening the privacy and safety of children, especially on TikTok. As this content gained popularity it became monetizable through influencer marketing, or paid partnerships with brands, and created a form of sharenting referred to as family influencing. Influencer marketing encourages the development of parasocial relationships (PSRs) to build a loyal audience for financial success. PSRs develop when a viewer forms a non-reciprocal relationship with a figure through a series of one-sided, mediated interactions simulating face-to-face or intimate interactions. The present …

Playing Makes Believing: Narrative Creation In Tabletop Role-Playing Games, Evan Salthouse

University Honors Theses

Tabletop role-playing games (TTRPGs) are a medium of narrative creation that combine collaborative improvisation, dice rolling, and game mechanics to allow players to tell mythical stories of fantasy and adventure. How are TTRPG systems used to create such memorable, evocative narratives? This research paper analyses Dungeons & Dragons (D&D) 5th Edition, examining its multifaceted system of narrative creation and the forces of influence at play, and outlining how narrative emerges from each aspect of the game.

Rebellion In The Streets: Activist Art As A Tool For Resistance, Anika Nichols

University Honors Theses

This paper explores the connection between art, anarchism, and Black liberation through the works of Emory Douglas, the AfriCOBRA collective, and Betye Saar. It argues that these artists create a visual language as an expressive form of resistance. One that challenges state violence, capitalist exploitation, and the cultural distortion and marginalization of Black individuals. Framed through anarchist theory, including April Carter's The Political Theory of Anarchism along with writings by Emma Goldman and Lucy Parsons, the project places activist art within a broader tradition of anti-authoritarian ideology. Therefore, by staying rooted in community and rejecting centralized control, these creative practices …

"I Just Kind Of Wish People Knew We Existed:" Rethinking Queer Visibility, Identity, And Belonging In Rural America, Alyson C. Hagen

University Honors Theses

This thesis explores how LGBTQ+ individuals in rural America navigate identity, visibility, and belonging amid the pressures of metronormativity--the dominant cultural narrative that equates queerness with urban life. Through qualitative interviews with five queer adults who lived in rural settings, the study shows that rural queer life is shaped by not only structural erasure and limited resources but also adaptive strategies, emotional labor, and creative community-building. Participants described environments where queerness was often unspoken or denied, yet they developed contingent forms of visibility, online belonging, and grassroots kinship to survive and thrive. Although all participants had migrated to urban areas, …

Alloparenting And Male Infant Care Behaviors In Varecia Rubra (Red-Ruffed Lemur), Noelle Wilcox

University Honors Theses

Nonhuman primates are known for their complex social structures that sometimes includes cooperative breeding strategies. In recent years there has been an increase in investigating alloparenting (infant care provided by an adult or subadult that is not a genetic parent) and male infant care, and how such behaviors contribute to the overall assistance to the extreme energetic investment and costs of the mother for the rearing of offspring. There is also debate to how male care has evolved in the primate clade, be it through the theory of kin selection or theory of mutualism. However, there is not enough research …

Visual Literacy Instruction At Scale: Developing Asynchronous Learning Objects For First-Year Art And Design Students, Jacqueline Huddle, Sarah Carter

Communications in Information Literacy

While learning modules are not new to academic librarianship, student-centered, asynchronous learning modules are an innovative approach not commonly considered within the academic librarianship literature. This article discusses the development and implementation of visual literacy asynchronous learning modules created by two librarians for a cohort of first-year studio art students. In creating these modules, the goal was to offer studio art students visual literacy instruction specific to their personal interests and future careers. Specifically, this article discusses the module design process and how student-centered learning can be incorporated into modules in order to offer deep learning opportunities.

Rebuilding Consent: Fear, Trust, And The Future Of Nuclear Energy, Austin Dunham

University Honors Theses

This thesis traces the cultural and emotional roots of nuclear fear in the United States and explores how those inherited anxieties continue to shape public resistance to nuclear energy in the face of a worsening climate crisis. Drawing on personal narrative, risk perception theory, and the history of nuclear discourse - from Hiroshima to Chernobyl to today - the research examines how trust, rather than technology, remains the largest barrier to progress. By analyzing the stories we tell about energy, disaster, control, and overall perceived risk, this work asks what it would take for Americans to imagine nuclear energy not …

Raising The Roof For All: Integrating Companion Planting Ecology, Policy And Community In Portland's Green Roof Future, Zoe Edelman

University Honors Theses

Green roofs, or ecoroofs, provide environmental and social benefits in urban areas. Ecoroofs manage stormwater by absorbing rainfall, reducing rooftop temperatures, supporting pollinators, and offering green space in densely developed cities. Portland, Oregon has adopted progressive policies that encourage green roof installation through incentives and building requirements. However, many ecoroofs in the city are underperforming due to poor maintenance, low public awareness, and limited access to rooftop spaces. This thesis explores whether companion planting can improve the ecological performance and long- term viability of extensive green roofs. A rooftop experiment at Portland State University tested the growth of radishes, with …

More Than Hormones: Psychological Consequences Of The Medicalized Menopausal Experience, Haley Derrickson

University Honors Theses

Menopause, a transitional period that roughly half the population may experience, has a high degree of variability in onset and intensity of symptoms, one of which is depression. It is also a period in which the lives of those transitioning are highly medicalized. This literature review investigates how medicalization has increased since the term was created, and how it impacts perimenopause, menopause, and mental health.

The Impact Of Nicu Death On Bereaved Mothers, Jennie Terranova

University Honors Theses

Infant loss in the United States occurs 5.6 per 1,000 live births. This paper examines risk factors that contribute to neonatal death. Prematurity is a risk factor for NICU admission. A portion of premature babies receiving care in the NICU will die. The stressful nature of the NICU has been studied widely in journals. The impact of NICU death on hospital staff and bereaved parents has been studied less. Mortality studies suggest that bereaved mothers are at a high risk of dying within the first 5 years after their child has died. Despite the frequency of maternal death post-child loss, …

American Consumer Culture And Social Media Polarization: Analyzing Twentieth Century Trends And Their Effects On Twenty First Century Politics, Max Lally

University Honors Theses

The emergence of social media as a mainstream communication technology during the early twenty first century has had an outsized impact on the United States' political system. By analyzing trends in American culture and economics beginning in the decades following the end of World War Two, the circumstances that shaped social media during its development can be tied to long term historical changes. Shifts away from traditional models of community and towards rising individualism reshaped communication with both political allies and opponents. Generational shifts in political attitudes have heightened these divisions as well, as younger and liberal perspectives challenge traditional, …

Drawing on gender …

Early-Stage Detection Of Copper Ion Release From Bronze Corrosion Using Uv/Vis Spectroscopy And Hydrogel Sensing, Hibah Khan

University Honors Theses

Detecting copper(I) (Cu⁺) release at early corrosion stages is important for preserving bronze heritage materials. This study investigated the use of neocuproine (NC), a Cu⁺-specific ligand, for simple and selective colorimetric detection of Cu⁺ in solution. NC reacts with Cu⁺ to form a Cu(NC)₂ complex, which produces a distinct orange-red color with peak absorbance at 455 nm. Solutions were prepared with varying concentrations of Cu⁺ generated by reducing Cu²⁺ with excess ascorbic acid. Ultraviolet/Visible (UV/Vis) spectroscopy was used to quantify absorbance changes. The absorbance at 455 nm increased linearly across the tested Cu⁺ concentration range (6.25–200 µM) with an R² …

A Postcolonial Re-Telling Of The Life And Times Of Dr. Bethenia Owens-Adair, Lucille Marie Walker

University Honors Theses

This thesis seeks to explore the story of Dr. Bethenia Owens-Adair, one of the first female doctors in the Pacific Northwest, who wrote the bill that would one day enact Oregon's long standing eugenic sterilization laws. Utilizing postcolonial framework primarily provided by psychiatrist and political writer Frantz Fanon, and supplemental literature from historian Ann Stoler, this paper will look into Dr. Adair's life story and her eugenic efforts in an attempt to understand the colonial roots of turn-of-the-century beliefs about bodies, behavior, and will ultimately aim to question how these beliefs may still reverberate through society today.

Surveying Management Strategies For Pediatric Autoimmune Hepatitis, Lillie Baca

University Honors Theses

Pediatric autoimmune hepatitis (PAIH) is a long-term condition that requires ongoing treatment and regular monitoring. It is characterized by its elevation of liver enzymes, interface hepatitis, and the specific presence of circulating autoantibodies. There is a general lack of consensus on appropriate measures of diagnostic criteria, treatment medication, and beneficial practices for monitoring the disease. The existing literature contains several subtle discrepancies that challenge a practitioner's judgement for care management of children with autoimmune hepatitis. This study is a retrospective chart review aimed at understanding the current diagnostics, treatment, and long-term management strategies of PAIH at a single center. Also, …
