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.

Exploring Vaccine Efficacy And Safety For Ms Patients On Immunosuppressant Treatment In Light Of The Covid-19 Pandemic, Rain Pross

University Honors Theses

Multiple sclerosis (MS) is a chronic neurodegenerative autoimmune disorder affecting approximately 2.8 million people worldwide. Despite decades of research to understand the molecular mechanisms of MS pathology, little is known about why the neurodegeneration caused by this illness occurs. For this reason, current treatments for MS target two broader aspects of the disease: relapse management and prevention via disease-modifying therapies. These treatments often involve immunosuppressive mechanisms, creating vulnerability to infectious diseases that became particularly concerning during the COVID-19 pandemic. This literature review examines the safety and efficacy of vaccination for MS patients on immunosuppressant therapies, highlighting the novel mRNA vaccines …

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, …

The Competitive Advantage Of Storytelling, Jennifer V. Carroll

University Honors Theses

Ava Roasteria Company, a family-owned coffee business in Washington County, Oregon, faces the challenge of expanding in a saturated market. Despite a compelling origin story rooted in environmental remediation and community revitalization, Ava has not utilized this narrative in its branding. This capstone project applied strategic business and marketing frameworks to identify narrative storytelling as a key competitive advantage. Research shows that authentic, narrative origin stories of small businesses that align with stakeholder's values and beliefs can foster emotional connection, loyalty, and brand differentiation. Ava's history and alignment with the Portland culture of sustainability and social responsibility is an untapped …

Access to healthcare is considered a basic human right, yet many Hispanic and Latin immigrant populations in the United States, especially those living in rural areas, face significant barriers that prevent them from receiving the care they need. These barriers include language differences, cultural misunderstandings, financial hardship, fear of legal consequences, and geographic isolation. This literature review explores the challenges that Hispanic/Latin immigrants aged 19-25 in rural areas encounter when trying to access healthcare, particularly preventative services.

Drawing from a wide range of existing research, this thesis identifies how policy restrictions, social determinants of health, and systemic discrimination contribute to …

Controlling Corsets: Commerce, Dress Reform, Medicine, And Misogyny In Nineteenth-Century Women's Dress, Emily Klesch

University Honors Theses

In the nineteenth century, women's dress depended on the usage of the corset. Without it, a woman's outfit was uncomfortable to wear and largely impractical. Because of how necessary the garment was to women's clothing, it became the focus of criticism from many different angels, including but not limited to the medical field, dress reform, and businesses which manufactured and sold corsets to consumers. These criticisms, although directed at the corset, were often thinly veiled insults to the female sex, and reflected larger societal fears about women's places in society as women's liberation movements began to gain more traction. It …

Messy Kitchens, Clean Hands, Emily Camp

University Honors Theses

Contemporary industrial food systems are well-tuned towards their primary goal: the efficient production of cheap food to generate high profits. Perhaps nowhere is this more acute than in the production of industrial meat. Here, workers, consumers and animals are trapped in a system that ignores their interests in order to achieve maximum profit for shareholders. But how does modern industrial meat production remain mostly hidden from view?

This interdisciplinary art and cultural history thesis explores this question by looking to the kitchen, and more specifically, to its decor. These decorative objects both reflect and enable a complex ideological transformation. I …

The Rainbow War: Ballot Measure 9 And The Fight Over Gay Rights In Oregon, Patrick Douglas Lasalle

Dissertations and Theses

On November 3, 1992, Oregonians were asked to vote on Ballot Measure 9, an amendment to Oregon's constitution that would prohibit anti-discrimination protections for homosexuals, prohibit the use of public funds and facilities to "promote" homosexuality, and require schools to actively discourage homosexuality as "abnormal, wrong, unnatural, and perverse." In this narrative history, I will explore Measure 9 and the ways in which it divided the state, beginning with its introduction in May 1991. I examine the history and reasoning of the Oregon Citizens Alliance, the Christian Right organization behind the measure, as well as the gay and lesbian community’s …

Price-Signal-Based Control Strategy For Heat Pump Water Heaters In Demand Response Applications, Othman A. Murad

Dissertations and Theses

This work presents a price-signal-based control strategy for residential Heat Pump Water Heaters (HPWHs) aimed at reducing electricity costs and shifting load away from high-price periods. By integrating the California Load Flexibility Research and Development Hub (CalFlexHub) prototype price signals, the Consumer Technology Association (CTA-2045-B) communication protocol, and the Object-oriented, Controllable, High-resolution Residential Energy (OCHRE) simulation framework, a rule-based controller was developed to align HPWH operation with dynamic electricity pricing while maintaining hot water availability.

Influencing Factors Of Angle-Of-Arrival Estimator Based On Deep Learning, Guohao Pang

Dissertations and Theses

Deep learning (DL)-based angle-of-arrival (AoA) estimation offers significant advantages over traditional signal processing methods, especially in complex and high-noise environments. However, situational complexity and differences in hardware can significantly impact the estimator's performance. It is therefore of interest to investigate the relationship between the performance of deep learning models and the variation of physical parameters such as the number of signal sources, the number of receiving antennas, and the signal-to-noise ratio (SNR). In this study, we investigate the impact of these variations on deep learning-based AoA estimation by systematically analyzing how the variations in the characteristics of the received signal …

The Silk Butterfly Effect: Japan And The United States 1853-1941, Melodee Birlew

Dissertations and Theses

This study examines the rise and fall of the silk industry in both the United States and Japan in the first half of the twentieth century. While silk had been a valuable commodity for millennia for royalty, aristocrats, and the extremely wealthy, the opening of Japan's ports in 1853 soon made silk more accessible to lower classes around the world.

Consequently, Japan's newfound wealth catapulted her status among other rich and powerful nations. Japan's military might, financed in large part by the silk trade and displayed by her victory over Russia in 1905, earned her even more prestige on the …

Their Will Is Wealth: American Billionaires, Illiberal Capital, And Their Immunity To Federal Law, Conor Kawika Carroll

Dissertations and Theses

Billionaires are inherently unique political actors. They, and their wealth, are a species apart. This rarity is measurable by quantifying relative consequences for actions made on behalf of that wealth. This thesis explores whether or not a billionaire's political power provides them with immunity to federal laws and regulations that govern wealth and its political use. The objective of this research is two-fold: to illustrate the scholarship gap regarding American billionaires and their relative immunity from federal law, and to instigate academia to study billionaires politically at increasing rates, providing more data for lawmakers regarding the most economically powerful political …

"We're Not Gonna Take It": The Parents' Music Resource Center And Reformist Tendencies In American Society, Nathaniel Todd Belcik

Dissertations and Theses

The Parent's Music Resource Center is a cultural curiosity that few historians have examined. Started by Tipper Gore and Susan Baker, the wives of prominent politicians, they advocated for a warning label on music with explicit lyrics and achieved their goal within only a few years of their creation. This thesis aims to contextualize the PMRC within a broader context of middle-to-upper class reformist movements. Many have argued that the PMRC falls on the conservative end of the political spectrum. Yet, a more complete story can be told by situating the organization within a reformist tendency in American history, thus …

Navigating Sovereignty And Human Rights: A Legal Analysis Of Palestinian Detention Under Israeli Jurisdiction In Comparison To International Law, Amani Nidal Odeh

Dissertations and Theses

This thesis examines whether Israeli detention practices of Palestinians conform to or contravene Israeli domestic legislation and international legal standards using a doctrinal legal analysis. This thesis evaluates six key areas through four hypotheses: the detention of minors, geographic disparities (particularly Gaza), administrative detention procedures, the use of military courts, due process violations, and detention conditions. While Israeli domestic law formally authorizes these practices, the analysis finds they routinely violate crucial international legal norms, including the ICCPR, CRC, CAT, and the Fourth Geneva Convention. The use of secret evidence, prolonged administrative detention without trial, and discriminatory legal frameworks undermines the …

The Failure Of The Annan Plan And Suggestions For Peace In Cyprus, Haley Grace Morrow

Dissertations and Theses

The following study explicates the conflict in Cyprus between the Greek Cypriots and the Turkish Cypriots. The conflict began around 70 years ago and came to its height in the 1970s when a Greek coup occurred, and subsequently, Turkey invaded the northern part of the island. This drove the two parties apart physically and mentally. The Annan Plan, a UN peace plan in 2004, attempted to bring peace to the island by reunifying the two parties into a bi-communal federation. However, this plan failed as the Greek Cypriots voted against it. The failure of the plan was primarily due to …

"I'M Strictly T4t": Trans For Trans Connections In The Contemporary, Madi Lou Alexander

Dissertations and Theses

Trans for trans relationships, referred to as "t4t", are a relationship type specific to trans individuals. Linguistically originating from Craigslist personal ad spaces, t4t indicates a trans person seeking out and engaging with another trans person. The scope of relationships under the t4t label are often largely associated with sexuality and dating scenes due to their conception in online cruising spaces. Through qualitative analysis, I assess the range of what t4t relationships are through 30 in-depth interviews with participants identifying as trans. This work moves away from focusing on the deficits of holding a marginalized identity, instead aiming to center …

A House With No Walls Where Persimmons Grow In The Garden: Photography As A Collaborative Feminist Practice And Using Archives To Reframe The Present, Jada Wheeler

University Honors Theses

A House With No Walls is an investigation of the idea of chosen family, as it exists apart from the influence of any institution. It alludes to the home as a place that exists within space shared with the people we choose as family and within our own free bodies. This project investigates the collaborative potential of photography, and uses it as a tool in creating a feminist representation of family. All the photographs were made with close friends, in an unplanned and spontaneous manner, to document intimate moments of our everyday lives.

Prayer And Gunpowder, Muhammad Saqif Maqsud

Dissertations and Theses

Prayer and Gunpowder is the opening movement of a larger novel that reimagines piracy in the Mughal Empire through a lyrical, historically inflected narrative. Set in a fictional coastal city haunted by imperial fragility and foreign encroachment, the story follows a young boy, Adam, whose life is ruptured by colonial violence. What begins in the rhythms of everyday life--scarves in the market, whispered prayers, the jovial defiance of youth--erupts into loss, enlistment, and conscription into a crumbling navy that can no longer protect its shores.

The novel explores themes of grief, rupture, inheritance, and spiritual reckoning, filtered through the consciousness …

Implicit Ethical Consumerism: Development And Cross-Cultural Validation Of A Novel Affect-Misattribution Measure, Brandon Reich, Hong Yuan, Lamberto Zollo, Riccardo Rialti

Business Faculty Publications and Presentations

The literature has documented a pervasive attitude‐behavior gap in ethical consumption, whereby many consumers do not consistently translate their expressed positive attitudes toward ethical products into behavior. For marketers investing in social responsibility initiatives, this suggests that more accurate segmentation and demand forecasting may require an implicit measure of ethical consumerism. This study draws from literatures in ethical consumption and the psychology of attitudes to develop and validate such a measurement tool. Across three pretests and three studies, findings show that our implicit measure (based on the Affect Misattribution Procedure [AMP]) is cross‐culturally robust in predicting ethical consumption behavior beyond …

Retention Intervention Program Success: An Inquiry Into Learning Organization Structural And Cultural Elements In California Community Colleges, Paul Vernon Wickline

Dissertations and Theses

Community colleges serve a diverse, underrepresented, and economically disadvantaged student population, yet most students fail to complete their academic goals, with students from marginalized groups facing even more significant disparities. Some colleges have implemented Early Alert and Intervention (EA&I) programs to improve retention and completion rates. However, colleges may face organizational challenges in implementing and sustaining these retention programs. This qualitative study examined structural and cultural elements in community colleges that have successfully implemented EA&I programs, focusing on student services and student affairs practices that support a learning-centered environment. Findings suggest that effective EA&I programs are grounded in inclusive, collaborative, …

The Role Of Cultural Mathematical Caring Relations In Supporting Two Latina Undergraduates’ Rate Of Change Development Within A Constructivist Teaching Experiment: An Anti-Deficit Investigation Bridging Sensemaking And Cultural Experiences, Christopher Orlando Roman

Dissertations and Theses

This study introduces cultural mathematical caring relations (CMCRs) as a framework that extends Hackenberg's mathematical caring relations by integrating two tenets of culturally relevant pedagogy: academic achievement and cultural competence. Framed within radical constructivism, CMCRs prioritize students' cognitive growth and development while affirming their cultural and experiential identities by embedding their funds of knowledge into the learning process. Through a constructivist teaching experiment with two Latina students, Yari and Jocelyn, this research investigates how working to establish and maintain CMCRs can influence Latin* students' rate of change development.

Findings illustrate that CMCRs supported the development of Yari and Jocelyn's rate …

Spousal Bereavement Enhances Proinflammatory Cytokine Production To Acute, Psychological Stress., E Lydia Wu-Chung, Ryan L. Brown, Robert Suchting, Jensine Paoletti-Hatcher, Michelle A. Chen, Angie S. Leroy, Kyle W. Murdock, Cobi J. Heijnen, Christopher P. Fagundes

Psychology Faculty Publications and Presentations

Early widowhood is characterized by chronic stress and is associated with a higher risk of incident depression and cardiovascular-related morbidity and mortality. Peripheral inflammation is involved in the pathogenesis of major depressive disorder and atherothrombosis and may represent a common mechanism underlying widow(er)'s elevated risk for both health conditions. Chronic psychological stress sensitizes the release of proinflammatory cytokines during the peripheral stress response. The present study examined whether recent spousal bereavement enhances the inflammatory response to an acute, psychological stressor. Recently widowed older adults (n = 143) and non-widowed controls (n = 69) participated in a quasi-experimental study, during which …
