Exploring The Association Of Vitamin B12 Deficiency And Dental Health In Older Adults, Man Hung, Amir Mohajeri, Jacob Marx, Corban Ward, Martin S. Lipsky

Institute on Aging Publications

Background

Vitamin B12 plays a crucial role in overall health, yet its impact on dental health, particularly dental caries, remains underexplored. Older adults are at an increased risk of vitamin B12 deficiency and dental disease, but the relationship between these two factors is not well understood. This study examines the association between serum vitamin B12 levels and dental health in older adults using data from the NHANES 2011–2014 cycles.

Methods

A cross-sectional analysis was conducted using NHANES data from 1,907 participants aged 65 and older. Serum vitamin B12 levels were categorized as normal (>221 pmol/L), marginal (148–221 pmol/L), and …

The Role Of Neuroscience In Mental Health Management Within The Adhd Population, Kadi Rae Smith

University Honors Theses

Neuroscience-based educational interventions play a role in the management of Attention Deficit Hyperactive Disorder (ADHD), including the regulation of ADHD-correlated depression and anxiety. Existing research shows that elevated rates of depression correspond to anxiety within the ADHD community; approximately 8.83% of the global population. Social ostracization and isolation are established contributors to depression and anxiety which are commonly comorbid with ADHD. The need exists for further investigation of the beneficial impact that an accurate, biological understanding of how the brain works has on the mental health of the ADHD population, and by extension their families, education systems, and medical industries. …

The Discovery, Communication, And Implementation Of New Geologic Findings: Examining The Cascadia Earthquake, Saylor Brainard

University Honors Theses

The Cascadia Subduction Zone, located off the Coast of the Pacific Northwest, is at risk of generating a 9.0 magnitude earthquake in the near future. Despite its significance, the discovery of the seismic potential of Cascadia didn't occur until 1987, when geologist Brian Atwater searched for non-traditional forms of earthquake evidence. As decades of continued research fleshed out Atwater's initial discovery, the implications associated with the discovery became apparent, presenting Washington and Oregon with the high probability that a massive earthquake will take place within the next century. Communicating the severity of this geologic discovery to both the public and …

Self-Representation In Manga: The Importance Of Gay & Lesbian Visibility In Japanese Society, Rylan Newsom

University Honors Theses

This thesis examines the evolving landscape of gay and lesbian self-representation in Japanese manga through a hermeneutic analysis of three key texts: My Lesbian Experience with Loneliness by Kabi Nagata, and My Brother's Husband and Our Colors by Gengoroh Tagame. It investigates how manga functions not only as a storytelling medium but as a sociocultural mirror, uniquely positioned to illuminate the often-invisible negotiations of identity, shame, and social position that queer individuals experience in Japan. Through the lens of Takie Lebra's concept of bun (role or place in society), this project explores the ways in which queer characters seek legitimacy, …

Working Paper No. 103, Russia And The Myriad Of Challenges Associatedwith ‘Relative Backwardness’, Jacob Wood

Working Papers in Economics

This inquiry seeks to establish that over recent of centuries Russia exhibits signs of what is termed as ‘relative backwardness.’ Drawing from Alexander Gershenkron’s (1962, 62-70) understanding of ‘backwardness in historical perspective,’ as well as Karl Marx’s ([1845] 1977, 39-43) concept of ‘historical materialism,’ this inquiry examines how successive Russian regimes sought to close the developmental gap with western countries through state-led modernization efforts. What stands out is that when confronted with attempting deep structural challenges, each leader turned to centralized authority and coercive reforms—not by choice, but out of necessity. Our inquiry considers Nicolas II’s failure to modernize Russia’s …

Testing Their Limits: Impact And Intentions Of Standardized Testing In K-12 Schools, Grace O. Herd

University Honors Theses

The integration of High-Stakes standardized testing into U.S. public education to serve as an accountability system has been a disputed issue since the No Child Left Behind Act (NCLB) mandated these assessments nationwide in 2002. NCLB aimed to locate and identify schools failing to reach Adequate Yearly Progress (AYP) and trigger a chain of interventions based on student performance, as an effort to track measurable outcomes from federal education funding. While supporters view these standardized tests as quantifiable data for school effectiveness in academics, critics challenge the claim of validity.

This review integrates current psychological research in the area of …

Pvc Biodegradation Potential Of Native Fungal Strains From Mt. Hood National And Tillamook State Forests, Bristol Ozturgut

University Honors Theses

Polyvinyl chloride (PVC) is a toxic, degradation-resistant environmental waste product. Recent research has revealed fungal enzymatic activity capable of biodegrading plastics. As PVC infiltrates local environments, it becomes imperative to determine the adaptability of local fungi to PVC substrates. In this experiment, 100 local native fungal strains sampled from the Tillamook State and Mt. Hood National forests and one commercial strain of common oyster mushroom were investigated for their ability to colonize and digest PVC by direct isolation on 0.1% and 0.2% PVC-enriched limited growth media. Substrates for positive cultures were imaged using Fourier transform infrared spectroscopy to analyze potential …

Where's The Dim Sum? Art, Oral History, And The Chinese American Diaspora In Portland, Or, Rayli Dornan

University Honors Theses

This thesis examines the history, transformation, and contemporary significance of Portland's Chinatown through an oral history framework, emphasizing the voices of Chinese American artists. Beginning with a comprehensive historical overview from the mid-nineteenth-century Gold Rush migrations and railroad labor to twentieth-century exclusion, dispossession under urban renewal, and the late-twentieth-century dispersal into suburbs, the thesis traces how structural racism and policy shaped both the physical landscape and communal life of Oregon's Chinese diaspora. Through in-depth interviews with local artists, this research aims to illuminate how individual experiences of identity, belonging, and creative expression navigate the tensions between heritage and adaptation.

Drawing …

Working Paper No. 97, Business Sabotage In Theory And Practice, Nathan Lewis-Lusso

Working Papers in Economics

This inquiry seeks to establish that theoretical advances offered earlier on by one Karl Marx and some decades later by one Thorstein Veblen offer insights into forms of business sabotage. Drawing upon their writings, this inquiry considers how in the writings of Marx, already in the mid-nineteenth century surplus value extraction and pecuniary sabotage serve as structural features found in a market-based economy. Marx’s consideration of surplus labor and artificial scarcity reveals how private investment seeks to constrain production in order to preserve and enhance profitability. Veblen’s theory of institutional sabotage complements Marx’s view by showing how firms could delay …

Is Anoxia Tolerance A Common Trait In Fish Cell Lines?, Lori Tran

University Honors Theses

Most vertebrates need a constant supply of oxygen to sustain life, with disruption to O₂ supply or delivery quickly leading to cell and tissue damage and death. Many aquatic species are able to withstand long periods without O₂ due to evolving to survive the regular periods of hypoxia and anoxia in their natural habitat. The Austrofundulus limnaeus, or the annual killifish, in particular have shown the highest anoxia tolerance in all vertebrates and is a promising model for developing effective treatments for anoxia-related damage, such as heart attacks and strokes. The A. limnaeus are not the only …

Beyond Capitalist Realism: Indigenous Worldviews As Critique And Alternative, Celine Jessup

University Honors Theses

This paper engages Mark Fisher's Capitalist Realism: Is There No Alternative? as a foundational critique of late capitalism's ideological dominance, and proposes Indigenous worldviews as both a critical lens and a generative alternative. Fisher defines capitalist realism as a pervasive structure that colonizes imagination, depoliticizes systemic crises, and renders other ways of living unthinkable. He illustrates how capitalism commodifies resistance, pathologizes dissent, and obscures accountability, particularly through institutions like the call center and discourses on mental health and climate change. In contrast, the paper turns to Indigenous political theories—drawing on thinkers such as Kim TallBear, Daniel Heath Justice, Ocean Ripeka …

Changing Minds, Changing Modes: Optimizing Public Perception Strategies For Urban Cycling Through Behavior Change Theory, Brandon Barnhart

University Honors Theses

This thesis addresses the recent decline in bicycle mode share in cities like Portland, Oregon, despite decades of investment in cycling infrastructure. While the "build it, and they will come" approach succeeded through the early 2000s, it no longer meets targets for bicycle use or broader goals related to sustainability, congestion, health, and safety. A new approach is needed that effectively rebuilds the cultural and behavioral components of cycling. This research asks: What role can behavior change theory play in increasing the effectiveness of public perception campaigns to promote urban cycling? Using a qualitative methodology, this study draws on behavior …

The Intersection Of Education And Empowerment: How Comprehensive Sex Education Equips Adolescents To Navigate Complex Relational Dynamics, Joleigh Wood

University Honors Theses

This thesis examines the impact of comprehensive sex education (CSE) on adolescents' understanding of consent, personal boundaries, and relational competence. Drawing upon social learning theory, intersectionality, and relational-cultural theory, the study employs a multidisciplinary framework to analyze how CSE functions as both an instructional practice and a sociocultural intervention. Utilizing an integrative thematic review of empirical studies, policy analyses, and national curriculum standards, the research evaluates the extent to which CSE promotes emotional literacy, fosters ethical relationship skills, and addresses structural inequities in educational access. Findings indicate that well-implemented, inclusive CSE contributes to healthier developmental outcomes by enhancing students' emotional …

Did Dobbs Reduce The Supreme Court's Legitimacy?, Ava Steinmetz

University Honors Theses

This thesis examines the impact of the Dobbs v. Jackson Women’s Health Organization decision on public perceptions of the Supreme Court's legitimacy. Over the two decades preceding Dobbs, the Roberts Court had already become the center of intense debate over judicial impartiality, driven by an increasingly politicized series of high-profile rulings. Dobbs generated an unprecedented level of media attention and partisan commentary. Employing a mixed-methods approach, this study combines longitudinal analysis of national survey data on trust and confidence in the Court with content analysis of editorial and scholarly reactions before and after June 2022. Findings reveal a statistically …

Shadowed Identities: The (Mis)Representation Of Communities Of Color In Classic Film Noir, Yolanda Porter

University Honors Theses

This thesis is an inquiry into the (mis)representation of women, Latinx, and BIPOC individuals in classic film noir, examining how race, gender, class, and sexuality intersect to perpetuate stereotypes in Hollywood. Through a deep analysis of films like Gilda (1946) and Touch of Evil (1958), this project explores how the conventions of film noir, such as chiaroscuro lighting, moral ambiguity, and non-linear storyline, work to expose and also reinforce social hierarchies that preserve whiteness and oppression of minorities. The research positions these films within the postwar socio-political context of the United States, addressing the influence of the Hays Code, Cold …

Intersectional Realities, Multi-Dimensional Films: Reading Julie Dash's Illusions As An Activist Text, Amelia Morrison

University Honors Theses

This paper reads Julie Dash's 1982 film Illusions as an activist text, which challenges dominant cinematic and historical narratives through its Black feminist perspective. It explores the cinematic and narrative devices that Dash uses--including the weaving of fantasy and history, the strategic use of period aesthetics, and masking--to expose and subvert the mechanisms of white supremacist and patriarchal hegemony within Hollywood. Drawing on intersectional feminist theory from scholars like Kimberlé Crenshaw, Patricia Hill Collins, and bell hooks, alongside cinematic theory, this analysis demonstrates how Illusions critiques the historical erasure of people of color from United States cinema and history. By …

Freeing The Fremont: Visions Of A Post-Automobile Portland Highway Bridge, Henry Senters

University Honors Theses

The Fremont Bridge is an iconic piece of highway transportation infrastructure in the city of Portland, Oregon. Unfortunately, it is one of only three Willamette bridges in the city that does not allow any pedestrian access, except for a single day every year during an annual bicycling event. Consider, however: what if that were to change, in a future less dependent on private automobile usage? Drawing on historical precedents of pedestrian and car-free bridges, this thesis proposes three types of pedestrian-focused programs which a car-free Fremont Bridge could host, each of which speaks to a current aspect of civic life …

Game-Based Learning As A Dynamic System: A Review Of The Literature, Meadow Mcgalliard

University Honors Theses

Game-based learning (GBL) in its development as a field has found itself at an ever-increasing complexity with regard to theories, design elements, and outcomes that define it. It's been long since proven that games produce learning and the ways in which this benefits educators and designers have broad applications, from direct game implementation to integrating GBL knowledge into non-game spaces. The density and complexity of design in GBL prove beneficial for learning opportunities, as the adaptability of design can create an almost infinite series of outcomes in a highly replicable manner. In this broad review, I attempt to display the …

Philosophy In Action: Ni Una Menos And Liberation Theory, Matthew D. Albertson

University Honors Theses

This thesis explores the intersection of philosophy and social movements, Enrique Dussel's Liberation Philosophy and the Ni Una Menos movement. It argues that Ni Una Menos not only enacts a philosophy of liberation through its mobilization against gender-based violence in Latin America but also critically expands Liberation Philosophy by foregrounding intersectionality and gendered forms of exclusion--often underexamined in traditional liberation theory. Using Dussel's concepts--Exteriority, Praxis, Critique of the Totality, Ethics of Life, and Transmodernity--the study analyzes how Ni Una Menos elevates the lived experiences of marginalized women and gender-diverse individuals into the public and political sphere. Through strategies …

This thesis discusses ideas brought up in these articles regarding the classification and conceptualization of NPD as a disorder, the role that shame plays in the pathology of NPD, the ways that shame is addressed through treatment, and public and practitioner held bias resulting from the stigmatization of the disorder. New and upcoming ways of conceptualizing the disorder are also briefly discussed as there has been a push to …

Diy Music Career, Griffin Schmeltzer

University Honors Theses

As we know, the music industry is changing. Where artists once needed access to extremely expensive gear, we now have access to tech that can create professional quality music at a fraction of the price. And where artists once needed labels to back and distribute their music, we're entering into an age where anyone can upload a song directly to the primary platforms consumers use to listen to music. This has led to an era where songs written and recorded in bedrooms are winning grammys (Billie Eilish). But for all the upsides of anyone being able to make and release …

University Honors Theses

This thesis examines the effects of legalized sports gambling on NCAA player welfare and the integrity of competition through a mixed-method analysis of NCAA reports, academic literature, and media sources. Data disclose that although the overall prevalence of gambling among student-athletes has decreased, these individuals are demonstrating more detrimental behaviors, including solitary gaming and incurring substantial losses in a single day. The emphasis on internet abuse associated with betting results has escalated, especially during prominent tournaments. The NCAA's instructional programs and data-monitoring agreements are compromised by ethical issues surrounding data monetization and varying state gambling rules. The research contends that …

Let's Talk About Sex, Baby! Gender Roles In Parent-Child Sexual Communication, Alexandra Henrici

Dissertations and Theses

Parent-child sexual communication remains a fruitful avenue to increase safe sex behaviors, which are currently in decline by today's adolescents. Historically, mothers have reported engaging in parent-child sexual communication more than fathers do. Previous scholarship suggests this difference could be due to traditional gender role beliefs or conflicts with traditionally masculine attributes. Using social cognitive theory and social role theory, this study conducted a cross-sectional survey on parents of children aged 9 through 16. Positive relationships existed between outcome expectations, self-efficacy, and level of detail in sexual and reproductive health conversations between parents and children. Though no statistical difference was …
