Marshlands And Monasteries: The Impact Of Weapon Deposition On Medieval British Christianity, Maia Lippay
Marshlands And Monasteries: The Impact Of Weapon Deposition On Medieval British Christianity, Maia Lippay
Young Historians Conference
This paper, using proven archeological evidence, time-specific literature, and references on monastic life, local tradition, and social concepts of mythology, draws a clear connection between the prevalent European Iron Age practice of ritual votive and weapon deposition into bodies of water and the state of Christianity in middle ages Great Britain. The ceremonial county of Lincolnshire, particularly the Witham Valley, is featured heavily for its high concentration of deposition and monastic sites in a verifiably close distance of each other. The paper explores the possibility that the existence of these pre-Christian ritual sites remained relevant throughout the Roman period through …
The Influence Of Plato’S Symposium: Love And Beauty Throughout Media & Culture, Anna E. Roberts
The Influence Of Plato’S Symposium: Love And Beauty Throughout Media & Culture, Anna E. Roberts
Young Historians Conference
The Ancient Greek philosopher Plato is unquestionably one of the most influential writers of philosophy in history. Through his various writings and works, Plato influenced the entire world's ways of thinking and discussion. In his dialogue The Symposium, Plato explores the humanistic complexities of love, beauty, and desire and shows various approaches to these topics, from mythological ideas to complex philosophical thought. The Symposium has managed to stretch far beyond the world of ancient Greece and has influenced the works of many different authors, artists, and writers. From Shakespeare in Renaissance-era England, to Freudian thought, the idea of Platonic Love, …
Fragments Of A Dream: Armenia And The Shadow Of Genocide, Ada A. Camp
Fragments Of A Dream: Armenia And The Shadow Of Genocide, Ada A. Camp
Young Historians Conference
Amidst the shadows of the war in Ukraine, in September of 2023, Azerbaijan’s military advancement into an ethnic Armenian enclave called Nagorno-Karabakh ended a thirty year conflict in just one violent day. The next morning, hundreds of thousands of Armenians fled, fearing ethnic cleansing and retaliatory killings. While the more recent history of this conflict is tied to the fall of the Soviet Union, Armenia and Azerbaijan’s disagreements have lasted for generations. The threat of ethnic violence and forced migration is not new to the Armenian people, and unfortunately still remains relevant. This paper deals not only with questions of …

The Cambridge Five Spy Ring: The Notorious Bane Of The British Government, Jenna G. Mccomas
Young Historians Conference
Beginning with the communist recruitment of Kim Philby in 1934, this paper traces the decades-long espionage journey of the notorious Cambridge Five spy ring. Exploring the reach they had from the halls of the British government to Washington D.C, this paper highlights the building blocks of the Five’s legacy and their implications. This paper details the levels of and effects of British governmental incompetence in cementing the Five as international spy celebrities and enabling their Soviet espionage endeavors. Overall, it seeks to explore how the British were the agents of their own humiliation regarding espionage, and unnecessarily increased tension with …
Identity In Question: Middle Eastern Americans In Dearborn, Michigan, Julian F. Balsley
Identity In Question: Middle Eastern Americans In Dearborn, Michigan, Julian F. Balsley
Young Historians Conference
In the 2020 United States Census, fifty-four percent of the population of Dearborn, Michigan, identified as being of Middle Eastern or North African descent. The story of how a small Detroit suburb became the American city with the largest proportion of Middle Eastern citizens is one of transnational relations between the U.S., its ally Israel, and the Middle East. The city’s Arab American community grew out of continuous wars that pushed people out of their homelands throughout the second half of the twentieth century, as well as the rise of the American auto industry. What makes Dearborn unique is that …
A Matter Of Ultra Importance: How Ultra’S Decryption Of Enigma Impacted The Outcome Of World War Ii, Lia S. Hansen
A Matter Of Ultra Importance: How Ultra’S Decryption Of Enigma Impacted The Outcome Of World War Ii, Lia S. Hansen
Young Historians Conference
During World War II, one of the most prominent unsung heroes were the Allied codebreakers of Ultra who, under the thick blanket of absolute secrecy, worked tirelessly throughout the war to decrypt the German Enigma cipher. Efforts to break the Enigma cipher were underway since the beginning of the war but yielded little success until 1943 and Alan Turing’s Bombe. After this point, Allied forces were able to more effectively combat Axis forces, especially German U-boats in the Atlantic ocean, while keeping the whole operation under wraps to avoid suspicion and changing of the code. This paper explores how Ultra’s …
A History Of The Bracero Program As An Agent Of Transnational Modernity In The 20th Century, Lea H. Yonago
A History Of The Bracero Program As An Agent Of Transnational Modernity In The 20th Century, Lea H. Yonago
Young Historians Conference
The Bracero Program was an agreement devised between Mexico and the United States which provided a state-sanctioned avenue for Mexican men to work as contract laborers in the United States. It was originally intended to alleviate the World War II labor shortage in the United States, but would continue past the war until 1964. Its longevity was due to the central role it played in bringing Mexico and the United States into a modern, transnational relationship. I aim to examine the relationship between the two nations in two contexts: an historical-economic one, and an ethnographic one. These lenses are two …

The home-refill delivery system is a business model that addresses the concerns of plastic waste and its impact on the environment. It allows customers to pick up their household goods at their doorsteps and refill them into their own containers. However, the difficulty in accessing customers’ locations and product consolidations are undeniable challenges. To overcome these issues, we introduce a new variant of the Profitable Tour Problem, named the multi-vehicle profitable tour problem with flexible compartments and mandatory customers (MVPTPFC-MC). The objective is to maximize the difference between the total collected profit and the traveling cost. We model the proposed …
Trust Model Measurements For The Energy Grid Of Things, N. Sonali Fernando, John M. Acken, Robert Bass
Trust Model Measurements For The Energy Grid Of Things, N. Sonali Fernando, John M. Acken, Robert Bass
Electrical and Computer Engineering Faculty Publications and Presentations
Information security is essential for the reliable operation of an Energy Grid of Things (EGoT). In addition to basic information security protocols as defined by published standards, there is a need for a monitoring function that measures the trustworthiness of the various actors participating in an EGoT. We describe in this paper the implementation and evaluation of a Distributed Trust Model that was developed specifically for monitoring communication within an EGoT. We then show how the model parameters are set using statistical measures for hypothesis testing.
Does Assisted Living Provide Assistance And Promote Living?, Sheryl Zimmerman, Robyn Stone, Paula Carder, Kali Thomas
Does Assisted Living Provide Assistance And Promote Living?, Sheryl Zimmerman, Robyn Stone, Paula Carder, Kali Thomas
Institute on Aging Publications
Assisted living has promised assistance and quality of living to older adults for more than eighty years. It is the largest residential provider of long-term care in the United States, serving more than 918,000 older adults as of 2018. As assisted living has evolved, the needs of residents have become more challenging; staffing shortages have worsened; regulations have become complex; the need for consumer support, education, and advocacy has grown; and financing and accessibility have become insufficient. Together, these factors have limited the extent to which today's assisted living adequately provides assistance and promotes living, with negative consequences for aging …
Mixing Customer Ingratiation Into Evaluation: How Service Providers Judge And Evaluate Rideshare Experiences, Yazhen Xiao, Jonathan Hasford
Mixing Customer Ingratiation Into Evaluation: How Service Providers Judge And Evaluate Rideshare Experiences, Yazhen Xiao, Jonathan Hasford
Business Faculty Publications and Presentations
Whereas consumer satisfaction is critical for the success of services, we research how providers evaluate customers in the sharing economy represented by the rideshare marketplace. We examine anticipated customer evaluation (ACE) as the underlying link and the provider's sense of power as a moderator for the relationship between customer ingratiation and provider evaluations. We first conducted a field pilot study and analyzed the content of rideshare trips described by drivers. Then, we tested the conceptual framework in four experiments that manipulated different rideshare customer behaviors (self-presentation, other-enhancement, and customer conformity). Our study contributes to the consumer research literature by examining …
Exploring Affective Experiences Of Queer Individuals Navigating Relationships With Evangelical Parents, Grace Pappas
Exploring Affective Experiences Of Queer Individuals Navigating Relationships With Evangelical Parents, Grace Pappas
School of Social Work Faculty Publications and Presentations
An abundance of scholarship explores and discusses the process of queer identity development, including the experience of disclosing one’s queer identity, often referred to as coming out. Coming out to one’s parent(s) can be a challenging and complex experience for queer individuals, particularly for children from religious families. In this study, I explored the nuanced relationships between queer individuals and their Evangelical parents. I conducted qualitative interviews with nine participants. Using thematic analysis and Ahmed’s theory of affect and happy objects, I constructed four themes: (a) learning the affect queer carries, (b) feeling the affects of being queer, (c) how …
Volcanic Glass As A Proxy For Paleotopography Suggests New Features In Late-Miocene Oregon, Julian Cohen, John Bershaw, Richard Hugo
Volcanic Glass As A Proxy For Paleotopography Suggests New Features In Late-Miocene Oregon, Julian Cohen, John Bershaw, Richard Hugo
Geology Faculty Publications and Presentations
Volcanic glass has been used extensively as a paleoaltimeter. Deuterium (2H) concentrations in glass have been found to be stable over geologic timescales, making δ2H (also known as δD) a reliable proxy for ancient water chemistry. However, continued work revolves around better understanding how different factors affect preserved water in volcanic ash. Here, we analyze δD in the Rattlesnake Tuff (RST), a widespread ca. 7 Ma ash-flow tuff, and create a paleoisoscape to assess variations in δD across Oregon during that time. To this end, 16 ash samples were collected across central and eastern Oregon from …

In preparation for the special issue: Cascading Crises: Power, Equity and Liberation, the Editors of NWJTE sat down for a conversation with Dr. Liza Finkel, a Science Teacher Educator in the Graduate School of Education and Counseling at Lewis & Clark College. Dr. Finkel’s passions include science (especially geology), finding intersections between science and social justice and helping new teachers learn to include those connections in their teaching, knitting, cooking, birding, and reading mystery novels with women protagonists.
Preservice Teachers Learning To Teach In An Anti-Racist/Climate-Justice Program: Challenges And Promises, Richard Sawyer
Preservice Teachers Learning To Teach In An Anti-Racist/Climate-Justice Program: Challenges And Promises, Richard Sawyer
Northwest Journal of Teacher Education
The global climate crisis represents the most urgent problem facing the planet, impacting social, cultural, political, economic, and environmental dimensions of life. Alarmingly, it has impacted communities of color in disproportionate ways (Goddell, 2023; Pellow, 2013). The climate crisis, along with the intertwined context of racism, places a profound responsibility on social justice teacher educators to prioritize addressing these issues in teacher preparation. The intent of the following two case studies is to explore the impact of a project based teacher preparation program focused on cultural and environmental justice on the pedagogical knowledge and practice of teaching interns at the …
Feminist Political Ecology In The Classroom, Ella J. Yeigh
Feminist Political Ecology In The Classroom, Ella J. Yeigh
Northwest Journal of Teacher Education
As the effects of climate change are being felt more frequently, discussions on how to combat such a massive issue are increasingly prevalent. Finding solutions to the climate crisis requires an understanding of how mainstream economic systems have led to the climate crisis and using these same principles to get out of the climate crisis is misguided. Economic actions have inherent value biases that have real political effects. Feminist Political Ecology (FPE) as a theoretical model presents a better understanding of how values that are inherent in economic models such as reliance on efficiency, markets, and continual economic growth have …

Electron-Phonon Interaction Mediated Gigantic Enhancement Of Thermoelectric Power Factor Induced By Topological Phase Transition., Zhi Li, Koushik Pal, Huiju Lee, Chris Wolverton, Yi Xia
Mechanical and Materials Engineering Faculty Publications and Presentations
We propose an effective strategy to significantly enhance the thermoelectric power factor (PF) of a series of 2D semimetals and semiconductors by driving them toward a topological phase transition (TPT). Employing first-principles calculations with an explicit consideration of electron-phonon interactions, we analyze the electronic transport properties of germanene across the TPT by applying hydrogenation and biaxial strain. We reveal that the nontrivial semimetal phase, hydrogenated germanene with 8% biaxial strain, achieves a considerable 4-fold PF enhancement, attributed to the highly asymmetric electronic structure and semimetallic nature of the nontrivial phase. We extend the strategy to another two representative 2D materials …
Shifting Gears: Toward A New Way Of Thinking About Transportation, Susan Handy
Shifting Gears: Toward A New Way Of Thinking About Transportation, Susan Handy
PSU Transportation Seminars
The transportation system in the U.S. has been shaped by a core set of ideas that are embedded in professional practice. These ideas – freedom, speed, mobility, vehicles, capacity, hierarchy, separation, control, and technology – have produced a system in which most people are dependent on driving, with all the negative consequences that entails. Shifting to a system that offers people choices about their daily travel requires a shift in thinking on the part of the transportation profession. In this talk, I take a critical look at the way of thinking that, for the last century, has shaped our transportation …

Mass Capture Fishing In The Marquesas Islands, Reno Nims, Patricia Pillay, Melinda S. Allen
Anthropology Faculty Publications and Presentations
Mass capture of small fishes with a variety of nets, traps, and weirs was widely practiced and economically important across East Polynesia at western contact. Archaeological research, however, has suggested these technologies were less important during the early settlement period and gained prominence over time. Several explanations have been proposed, including resource depression, changes in marine environments, and/or social and economic reorientations. In the Marquesas Islands, pelagic and offshore fishes were historically well represented in early assemblages relative to most Polynesian islands. Here we report on fishbone assemblages from Nuku Hiva Island that were recovered with fine mesh screens, identified …

Chemistry Faculty Publications and Presentations
Studies of Electronic Nicotine Delivery Systems (ENDS) toxicity have largely focused on individual components such as flavour additives, base e-liquid ingredients (propylene glycol, glycerol), device characteristics (eg, model, components, wattage), use behaviour, etc. However, vaping involves inhalation of chemical mixtures and interactions between compounds can occur that can lead to different toxicities than toxicity of the individual components. Methods based on the additive toxicity of individual chemical components to estimate the health risks of complex mixtures can result in the overestimation or underestimation of exposure risks, since interactions between components are under-investigated. In the case of ENDS, the potential of …
Effective Dispersal Patterns In Prairie Plant Species Across Human-Modified Landscapes., Elizabeth C. Hendrickson, Mitchell B. Cruzan
Effective Dispersal Patterns In Prairie Plant Species Across Human-Modified Landscapes., Elizabeth C. Hendrickson, Mitchell B. Cruzan
Biology Faculty Publications and Presentations
Effective dispersal among plant populations is dependent on vector behaviour, landscape features and availability of adequate habitats. To capture landscape feature effects on dispersal, studies must be conducted at scales reflecting single-generation dispersal events (mesoscale). Many studies are conducted at large scales where genetic differentiation is due to dispersal occurring over multiple generations, making it difficult to interpret the effects of specific landscape features on vector behaviour. Genetic structure at the mesoscale may be determined by ecological and evolutionary processes, such as the consequences of vector behaviour on patterns of gene flow. We used chloroplast haplotypes and nuclear genome SNP …

Webinar: Marginalized Populations’ Access To Transit, Marisa Zapata
Webinar: Marginalized Populations’ Access To Transit, Marisa Zapata
TREC Webinar Series
How do people with intersecting marginal identities experience social exclusion as they travel via mass transit? To answer this question, PSU researchers employed a qualitative method less common in transportation studies: photovoice. Researchers asked participants to describe the factors that shape their travel behavior and provide photographic data of their experiences. Then, they conducted in-depth video interviews to gain further depth and clarity regarding the visual data. The findings from this study can help transit system designers better understand how experiences of harassment and discrimination across the entire users’ journey affects the riders’ decisions about whether and when to take …
