Entheogens: The Hallucinogenic Plants That Shaped Religion, Nicolas A. Michaud

Young Historians Conference

Entheogens have played a pivotal role in religious and spiritual practices across diverse cultures, aiding in the pursuit of divine connection and higher consciousness. Evidence suggests that dating as far as back as a million years ago, early human species such as Homo erectus and Homo habilis experimented with hallucinogenic plants like psilocybin mushrooms, introducing the earliest forms of shamanic practices. As societies became more structured, the use of entheogens expanded throughout various parts of society. In ancient Greece, oracles utilized plants like henbane to communicate with the divine, molding military and political policy. During the Middle Ages, Tibetan Buddhism …

Exposing The Truth Behind The Stanford Prison Experiment, Leo Novack

Young Historians Conference

In 1971 Philiip Zimbardo, a Stanford University professor, designed an experiment to study human behaviors in the prison system. He sought to understand the effectiveness of the prison system, however, the experiment ended early due to the ethical concerns toward participants. It is considered one of the most important psychological experiments, not for what it helped reform, but for what it pointed out about the importance of safety for research participants. Calling upon primary sources from participants and the researchers’ findings, as well as secondary sources primarily from psychologists and research ethics, the research reveals that this study was unreliable …

A Crucial Western Foothold: Uyghur-Americans In The Fairfax-D.C. Metro Area, Jake C. Mccauley

Young Historians Conference

Since the 1980s, the Uyghur people of East Turkestan, now known as the Xinjiang Uyghur Autonomous Region, have migrated from their ancestral homeland in China in search of a better life. As an ethnically, linguistically, and religiously distinct group, the Uyghurs face severe oppression, with the Chinese state targeting them economically, socially, and physically. Since 2017, mass internment efforts have escalated, leading to the establishment of labor camps that claim to transition Uyghur labor from agricultural to industrial sectors but also serve as sites of ideological indoctrination, torture, and death. As a result of these human rights violations and other …

A Revolutionary Curtain Call: Yiddish Theatre, The Jewish Enlightenment, And The Russian Revolution, Sidonie James

Young Historians Conference

This paper explores the impact of Yiddish Theatre in Moscow and broader Russia in the era of the Russian Revolution as a Jewish cultural and political force. The intersection of the Russian Revolution and the Jewish Haskalah reformation created the space for Yiddish theatre, a cultural movement combining Jewish identity with revolutionary ideals, to thrive. Yiddish theatre became a space for community discourse and political critique during Stalin’s rule, preserving Russian-Jewish cultural identity amid growing Soviet hostility. By examining the Russian Jewish community and its relationship to Russian government and society through the lens of Yiddish theatre, this paper reveals …

How The Cheating Of East And West Germany Reveals A Global Trend Of Doping In International Sports, Olivia L. Cheng Miss

Young Historians Conference

In 1989, the Berlin Wall fell, representing the end of both a deep physical and ideological divide between East and West Germany. The fall of the Berlin Wall revealed a state-sponsored doping program in East Germany created in order to compete for the political and economic symbol of strength: Olympic medals. Years later, the exposure of widespread West German doping in competitions shows the capacity of cheating to spread like a pathogen, passed from one nation to another in a pattern still visible today. Though East and West Germany were the epicenter of the doping outbreak, the trend spread globally …

Riding Through The Great Depression: The Impact Of Pack Horse Librarians, Madison G. Reed

Young Historians Conference

Supported by Eleanor Roosevelt and the Roosevelt Administration during the Great Depression, the Works Progress Administration (WPA) was part of Roosevelt’s “alphabet soup” agencies. It didn’t take long for the WPA, which sought to provide work, education, and culture to Americans who were struggling economically, to introduce the Pack Horse Library Project to rural Eastern Kentucky. The Pack Horse Librarians were local women hired by the federal government to bring reading material to isolated, unemployed people and children of all ages. Both secondary scholarship, focused on the role Pack Horse Librarians played in the development of community, as well as …

“Through Science To Justice” Magnus Hirschfeld’S Role In Queer Liberation, Katarina L. Stoll

Young Historians Conference

Magnus Hirschfeld was a scientist who researched sexuality and gender, as well as an activist for “sexual minorities.” He challenged previously held beliefs that homosexuality should be treated as an illness and is credited with being the first to view gender identity as separate from sexuality. Additionally, Hirschfeld argued that queer people simply act in accordance with their nature. Through the creation of various institutions, he worked to uplift the queer community through publishing his research, undertaking advocacy work, and creating safe spaces. Though not immune to the prejudices of his time, Hirschfeld was able to help improve the lives …

Face Value: Cosmetics As A Unit Of Historical Analysis, Sophie Durocher

Young Historians Conference

Cosmetics are a universal concept that have been inherent in society all throughout history. This paper explores four unique cultures from across the globe and their primary cosmetic of choice. A tube of lipstick from a Bronze Age Persian burial ground sheds light on the early uses and significance of lipstick in Ancient Persia. A compact of powdered pearls from China in the 11th century reveals the widespread importance of facial powder in China. The Maya applied paint and perfumes to denote social status and in ritual traditions, as evidenced by artwork and archaeological evidence. Ancient Egyptians famously painted their …

The Role Of Feline Goddesses In Advancing Women’S Rights In Ancient Egypt, Caitlin Moran

Young Historians Conference

The ancient Egyptians highly valued cats, worshipped female feline deities, and granted women more rights than other ancient civilizations. These three facts are widely acknowledged, but they have an intriguing link—and the key lies in the divine feline. This paper explores the extent to which ancient Egyptian feline goddesses, particularly Bastet, Sekhmet, and Mafdet, contributed to the treatment of women and their freedoms that surpassed those of women in other ancient civilizations. Examining historical records, religious artifacts, and scholarly journal articles, it illustrates how feline deities shaped gender dynamics in ancient Egypt. By analyzing the relationship between cats, feline deities, …

Teaching From Past Example: Various Interpretations Of Livy's Rape Of Lucretia, June Baeck

Young Historians Conference

The final kings of Rome were expelled in 509 B.C.E. after one of their princes raped a woman, driving her to end her own life. Pure and chaste, this woman was the utmost model of feminine virtue. Her death would bring great political change at the end of the sixth century B.C.E., but her story would be carried on and projected to provoke something similar for millennia. One significant driver of this was Titus Livius, who wrote of her in the first book of his Ab Urbe Condita, a history of Rome written c. 29 B.C.E. His account showcased …

Reflecting Life Back: The Influence Of Mirrors On Human World History, Helen F. Cruz-Uribe Bandstra

Young Historians Conference

Ten thousand years ago, humans first created mirrors. They were developed simultaneously all over the world, reflecting the innate human desire to see something so close to us, yet so hard to view. Our own face. While this invention had a simple initial purpose, it quickly became tied to many of the more complicated developments of human life, including, but not limited to, religion, power, and technology. We see this reflected in everything from the polished obsidian mirrors of Mesoamerica, used to commune with the gods and revered for their reflectiveness, to the bronze mirrors of Greece used in early …

Shanghai's Stateless Immigrants: Anti-Bolshevik Russians In Shanghai From 1917-1949, Anna E. Roberts

Young Historians Conference

Following the Bolshevik Revolution of 1917, thousands of anti-Bolshevik (commonly referred to as White Russians) fled to the city of Shanghai. Shanghai’s status as a free port with very few strict immigration laws facilitated their arrival and allowed them to reside within the city's foreign settlements. The city's complexities and the Russians' status within the city also exposed them to vulnerabilities, including poverty, discrimination, and the eventual geopolitical shifts that led to their ultimate displacement. Despite the issues that many faced, White Russians contributed to Shanghai’s cultural and economic life, opening up schools, religious institutions, businesses, and newspapers that maintained …

Cuadros De Casta: A Pseudo-Scientific Means Of Control And Racial Taxonomy In Colonial Mexico, Lucita Ocaña Dessen

Young Historians Conference

Casta paintings of 18th century Mexico are a prime example of an art form mixed with political propaganda, as the 4x4 style paintings depicted over a dozen racial mixings in one painting. Created by Mexican artists for the viewing of Spanish elites, Casta paintings helped to establish the racial hierarchy that continues to be embedded into Latin American society. This paper seeks to determine to what degree Casta paintings served as hierarchical means of Christian, Enlightenment-era colonial control.

Estimated Amounts Of Terrestrial Carbon Mobilized And Sequestered By The 1980 Mount St. Helens Eruption, Washington State, Usa, Lizzet G. Reyes

Dissertations and Theses

Volcanic eruptions significantly influence the geologic carbon cycle by emitting CO₂ and mobilizing terrestrial carbon pools. The 1980 Mount St. Helens (MSH) eruption offers a unique case study, triggering a massive landslide that displaced 2.7 km³ of sediment, buried 600 km² of forest, and disrupted regional carbon dynamics. Pre-eruption terrestrial carbon stocks, including aboveground biomass (AGB), dead biomass (D), and soil organic carbon (S), averaged 209.5 tC/ha. Post-eruption, total carbon density fell to 118.7 tC/ha, driven mainly by a 51% reduction in AGB, modest declines in D, and redistribution of S. Over 36 years, ecosystem recovery increased …

Assessing The Potential For A Novel Composite Integrative Passive Sampler (Cips) To Investigate Transboundary Movement Of Organic Chemicals In The Tijuana River Estuary., Zuying Feng, Flannery Mclamb, Damian Shea, Kesten Bozinovic, Chris Stransky, Richard M. Gersberg, Wenling Wang, Xiang Kong, Xin-Rui Xia, Miguel F. Vasquez, Mackenzie King, Goran Bozinovic

Center for Life in Extreme Environments Publications

Nearly all environmental monitoring and research of chemical exposure in the aquatic environment relies on grab sampling of water and/or sediment providing only a snapshot in time. Passive sampling of water provides a more representative estimate of exposure compared to grab sampling, but current passive samplers have a limited working range of chemical properties. We tested a novel Composite Integrative Passive Sampler (CIPS) that simultaneously accumulates both hydrophobic and hydrophilic chemicals in water in the Tijuana River Estuary (TRE) on the U.S.-Mexico border. Quantitative targeted analysis detected 169 of the 193 targeted chemicals, and 128 of them were detected in …

Seeking Common Ground With A Conversational Chatbot, Judit Dombi, Tetyana Sydorenko, Veronika Timpe-Laughlin

Applied Linguistics Faculty Publications and Presentations

Conversational AI is advancing rapidly, enabling significant improvements in chatbots’ conversational abilities. Currently, available conversational chatbots (e.g., Snapchat’s MyAI) appear to generate fairly realistic, often human-like output. As collaboration between humans and machines becomes more common, and AI systems are increasingly viewed as more than just tools, understanding human communication in such contexts is crucial. Despite the vast array of applications and the increasing number of human-bot interactions, research on how humans interact with conversational chatbots is scarce. One possible reason for this gap is that studying human-computer communication may require adaptations of existing pragmatic frameworks, due to the unique …

Evaluating Nature-Based Versus Generic Physical Activity Programs To Address Chronic Health Conditions: Lessons From An Oregon (Usa) Pilot Study, Randall Bluffstone, Ma Chan, Cort Cox, Melinda M. Davis, Caitlin Dickinson, Sahan T. M. Dissanayake, Jeffrey D. Kline, Himani Ojha, Sterling Stokes, Srilakshmi Vedantam, Multiple Additional Authors

Economics Faculty Publications and Presentations

Evidence appears to be building that direct exposure to natural landscapes characterized by significant green cover, such as forests, can help to reduce chronic health conditions such as obesity, stress, hypertension, chronic cardiovascular conditions, depression, anxiety, cancer, and diabetes. One way to encourage greater exposure to nature may be through the use of nature prescriptions, whereby clinicians formally recommend (or prescribe) time in nature to their patients. Based on self-reported data, we describe the implementation and lessons learned from a pilot field experiment examining the clinical use of nature-based versus conventional exercise recommendations in rural Oregon. We discuss the potential …

The Geologic History Of The Chehalis Forearc Basin, Washington State, Usa, Rud Lamb Moe

Dissertations and Theses

The Chehalis Basin, in southwest Washington, is one of a series of forearc basins between the Cascade Arc and the Coast Range in the Pacific Northwest. While the Seattle basin to the north, and the Portland-Tualatin basins to the south are both relatively well studied, the geologic evolution of basins in between is poorly constrained. The Chehalis basin is underlain by accreted Eocene oceanic basalt of the Crescent Formation. The basin fill consists of sedimentary rocks and volcanic rocks deposited throughout the Cenozoic. It has undergone N-S shortening driven by transpressional stress from oblique subduction of the Juan de Fuca …

Development Scenarios And Wildfire Risk In Central Oregon, Samantha Hall

Dissertations and Theses

Risk from natural hazards occurs where areas vulnerable to natural hazards and development intersect. Development in vulnerable areas is a societal choice that has a lasting impact as our built environment is relatively permanent. Development patterns that contribute to increased wildfire risk mostly occur within the wildland urban interface, a land use type where development is at the fringes or intercept of wildland areas and is more flammable due to surrounding vegetation, slope, local climate, and other factors. To understand how past and future development potentials may impact fire risk in wildfire prone areas, a case study of Deschutes County, …

The Effects Of School Safety Strategies On K-12 Schools: Armed Civilians, School Resource Officers, And Metal Detectors As Contributors To The School-To-Prison Pipeline, Rebeca Petean

Dissertations and Theses

In recent decades, K-12 public schools have introduced get-tough measures ostensibly to improve school safety through punitive responses to misconduct and delinquency--expanding from traditional security measures to more punitive, zero-tolerance policies and surveillance-based approaches. Academic literature and media accounts highlight that such efforts continue to proliferate and extend across our nation's school spaces. This three-paper dissertation examines how specific safety practices--namely, the presence of armed civilians, School Resource Officers (SROs), and random metal detector checks--influence student outcomes and contribute to the school-to-prison pipeline. Rooted in Becker's (1963) and Lemert's (1967) labeling theory, as well as Sampson and Laub's (1997) cumulative …

Geography Of Non-Daytime Work And Employer-Centered Transit Accessibility, Julia Mai Plotts

Dissertations and Theses

Non-daytime shift workers--including those on evening, night, rotating, and split shifts--face unique transportation challenges. Those who rely on public transit often contend with complicated commutes and longer wait times on public transit systems that have traditionally catered to the 9-to-5 workforce. Meanwhile, the non-daytime workforce is disproportionately composed of marginalized groups, including low-income workers, racial and ethnic minorities, and individuals with fewer education credentials. For many lower-income workers, car ownership does not present a viable alternative, as cost-of-ownership consumes a significant portion of their income. This makes access to nighttime public transit a critical equity concern. However, most transit accessibility …

Activity Levels Among Older Adults In A Life Plan Community, Emily D. Winters

A total of 166 survey respondents, aged 65 and older, were included in the analysis. Data were collected using a self-administered questionnaire designed to assess physical activity patterns, preferences for activity types, and engagement with the facility’s health and wellness offerings. Open-ended questions were assessed qualitatively through thematic analysis to find common themes within data. Results indicated that the most …

Academyhealth - 2024 Data Visualization Winners, Chelsea Keating, Emily Boniface, Mina Colon

OHSU-PSU School of Public Health Annual Conference

Social determinants of health, such as income, employment, social contexts, and the built environment, influence the risk of food insecurity. Food insecurity can be defined as uncertain access to food and can lead to negative health outcomes like increased risk for obesity, chronic disease, and adverse effects on a child's development and mental health. Drivers like limited physical access to food, limited transportation options, and the quality and access to food assistance programs within local systems perpetuate health disparities—particularly in those communities with populations who have been systematically marginalized. This descriptive study uses 2022 data from the National Health Interview …

Universal Health Care, Oregon, Jennifer S. Arnold, Bethany Clouse, Alec Martin

OHSU-PSU School of Public Health Annual Conference

Historically, the US has chosen not to fund universal health care at every opportunity, leaving our nation as the only industrialized country without some system of health coverage for our citizens and with the worst health care outcomes of any high-income nation in the world. Health care in Oregon is no exception. Our current health care system is financially unsustainable, harmfully complex, and socially unjust, as well as inequitably delivered. Too many Oregonians, because of their race, age, income, geography, or insurance, endure vastly different health care access, varied health care quality, and wide-ranging health outcomes. In 2019, the Oregon …

Primary Place To Go For Health Care And Its Association With Hpv Prevalence In Us Adults: Results From Nhanes 2013-2016, Amy L. Mcveety, Miyuki Sun

OHSU-PSU School of Public Health Annual Conference

Background: While access to health care is a known risk factor for many infectious diseases, including sexually transmitted infections, little research has investigated the relationship between access to primary care services and prevalent human papillomavirus (HPV) infection. Given HPV’s prevalence in the general population and lack of available treatments, it is necessary to understand possible risk factors to identify areas for intervention. This study uses primary place to go for health services as a proxy measure for access to care, in order to understand which sources of health care are serving patients with the highest prevalence of HPV infections and …

Effects Of Wetting Events On Mass Timber Surface Microbial Communities And Voc Emissions: Implications For Building Operation And Occupant Well-Being, Gwynne Á. Mhuireach, Susan Collins, Leslie Dietz, Patrick Finn Horve, Aurélie Laguerre, Dale Northcutt, Jason Stenson, Kevin Van Den Wymelenberg, Elliott Gall, Mark Fretz

Mechanical and Materials Engineering Faculty Publications and Presentations

IntroductionHumans have used wood as a construction material throughout history. Currently, mass timber products, such as cross-laminated timber (CLT), are becoming more popular as a structural material, since they are renewable and have a lower carbon footprint than concrete or steel. Nonetheless, some building types, such as healthcare, veterinary, and food manufacturing, avoid using structural mass timber due to concerns about microbial growth in the event of wetting. One solution is to use protective coatings on mass timber products to increase moisture resistance, although the coatings themselves may generate concerns about volatile organic compound (VOC) emissions. Natural uncoated wood also …

Perceptions About Potential Microplastic Interventions: A Study On Knowledge, Concerns, And Willingness To Pay, Amanda Gannon, Elise F. Granek, Max Nielsen-Pincus, Luke Harkins

Environmental Science and Management Faculty Publications and Presentations

Among emerging contaminants, microplastics (MPs) are of particular concern due to their ubiquity across environments and the unique challenges posed by attempted removal. In-line washing machine filters are one potential tool for preemptively preventing a category of MPs from entering waterways. A sample of registered voters and environmental interest groups in Oregon were asked about their general knowledge and concerns surrounding microplastics, as well as their willingness to pay for high-efficiency washing machine filters. Findings show that less than a quarter of all respondents would be willing to pay full price for a high-efficiency filter, indicating a limited-scale early adopter …

Acompañamiento And Assessment: Examples Of Community Building Through Assignments In A First-Year Class, Shaianne Tran, Hector Amezola, Dalissa Rodriguez, Morgan Baird, Jennifer Fuentes Luna, Alejandra Vazquez, Fattemah Zia, David Peterson Del Mar

Amplify: A Journal of Writing-as-Activism

This collection of seven diverse assignments written by students from under-represented communities for a first-year inquiry class on immigration, migration, and belonging illustrates how instructors can facilitate a sense of belonging or acompañamiento through course assignments, assessment instruments. Each of the student authors provides a retrospective introduction on how their personal reflection, essay, or research project helped them to make personal connections within or outside of the class. The instructor provides a brief introduction to the concept of acompañamiento and why it is particularly important for New Majority college students.

Manifesto Of An Arab Female, Diditta Rizk

Amplify: A Journal of Writing-as-Activism

In this manifesto, the author provides a window into her gendered experiences growing up female in the Middle East. In identifying the ways that women encounter obstacles to expressing their full agency in male-dominated societies, the author invites the reader to join her in redefining the narrative of what it is and means to be a woman. The manifesto ends with a call for us to become architects of a new perspective through which equity becomes reality, one where we strive collectively for peace, freedom, and the pursuit of the common good.
