Autism Risk Gene Cul3 Alters Neuronal Morphology Via Caspase-3 Activity In Mouse Hippocampal Neurons, Qiang-Qiang Xia, Anju Singh, Jing Wang, Zhong Xin Xuan, Jeffrey D. Singer, Craig M. Powell

Biology Faculty Publications and Presentations

Autism Spectrum Disorders (ASDs) are neurodevelopmental disorders (NDDs) in which children display differences in social interaction/communication and repetitive stereotyped behaviors along with variable associated features. Cul3, a gene linked to ASD, encodes CUL3 (CULLIN-3), a protein that serves as a key component of a ubiquitin ligase complex with unclear function in neurons. Cul3 homozygous deletion in mice is embryonic lethal; thus, we examine the role of Cul3 deletion in early synapse development and neuronal morphology in hippocampal primary neuronal cultures. Homozygous deletion of Cul3 significantly decreased dendritic complexity and dendritic length, as well as axon formation. Synaptic spine density significantly …

Permission To Play: A District's Initiative To Innovate Kindergarten And Promote Developmentally Appropriate Practices, Cristin Mcdonough

Dissertations and Theses

Kindergarten's original purpose was to promote socialization skills for young children using play. However, recent research has shown an increased focus on teaching literacy and math skills, combined with pronounced increases in more advanced academic tasks and activities. Given this shift in kindergarten, as well as a lack of professional development for teachers to assist them in promoting developmentally appropriate practices, the Kindergarten Innovation Cohort was created in the Portland School District to address these needs for both students and teachers. Using findings from interviews and field notes, the current study addresses the question: What does the implementation of the …

Mussar And Esotericism In Revolutionary Russia, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper is an introductory comparative look at teachings of two spiritual figures in pre-revolutionary and revolutionary Russia: Rav Yoseph Yozel (Horowitz) and George Gurdjieff. Yozel founded the Novarodok school of Mussar; Gurdjieff founded the spiritual tradition known as “the Work” or “Fourth Way.” There are of course great differences between the Jewish tradition of Mussar, whose literature dates back to the Mishnah but which as a social movement was launched by Rabbi Israel Salantar in the late 19^th century, and the Work, with its affinities to Eastern Christianity, Buddhism, and Sufism but with no apparent connection to Judaism. …

Static Reflective Surfaces For Improved Terahertz Coverage, Thanh Le, Suresh Singh

Computer Science Faculty Publications and Presentations

LoS (Line of Sight) MIMO (Multiple Input Multiple Output) is considered the best way to deliver high capacity channels for terahertz communications due to the severe attenuation suffered by reflected components. Unfortunately, terahertz links are easily blocked by any obstruction resulting in link breakage. Therefore, it is necessary to provide alternative paths via reflectors. A problem shared by LoS paths and reflected paths (via polished reflectors) is that the channel matrix is rank 1 in the far-field. As a result, the achieved capacity is lower than what can theoretically be achieved in a rich multi-path environment. In this work, we …

Faithful Coverage: The Irish Independent’S Catholic Transformation Of The Spanish Civil War, Willa M. Fahrbach

Young Historians Conference

In the summer of 1936, the Spanish Civil War erupted with a military coup d’etat against the current Republic, launching three years of chaos and casualty. Among the ranks of supporters for the imminent fascist regime were Fascist Italy, Nazi Germany, and shockingly, the majority of Ireland’s citizens. However, their support was not unprompted. The Irish Independent, a popular newspaper, flooded its pages with gory depictions of anti-clerical violence committed by the Spanish Republicans and steered their audience into the kind of righteous sensationalism that would later inspire an Irish Brigade to form on behalf of the fascist regime. …

Immigrant Identity Formation, A Transnational Approach: Italian Americans In New York City, 1880-1930, Amelia J. Vena

Young Historians Conference

Of the Italian immigrants arriving in America during the Great Migration (1880-1924), few understood themselves as “Italians.” On paper, Italian unification took place in 1861, but the creation of Italy as a unit of politics was not the creation of Italians as a unit of nation. Even decades later, immigrants landing in New York City understood themselves in regional terms—as Calabrians, Sicilians, and Neapolitans. “Italian national identity” remained an idea confined to the imaginations of wealthy and educated Italian nationalists. In the years that followed the Great Migration, immigrants reshaped Italian-American identity as they grappled with American ideas of race …

Jewish Immigrants In Argentina: The Bund As A Transnational Connection, Naomi Hemstreet

Young Historians Conference

Between 1881 and 1948, thousands of Eastern European Jews immigrated to Argentina, escaping subjugation and seeking economic opportunities. These Jewish immigrants initially worked in the agricultural colonies of the Pampas before settling primarily in Buenos Aires, drawn to the benefits of living in a densely populated city. Jewish socialism abounded, connected with the Bund in Russia and Poland while still existing independently. This paper examines the organization Avangard, the first representation of Bundism in Argentina, and its economic and cultural aims, before exploring Bundist schools in Argentina. I also analyze the secular Jewish schooling movement in Poland in order to …

Ceremonial Sexual Sacrifice To Commercial Prostitution: The History Of Prostitution And The Social, Economic, And Religious Progress That Revolved Around The Profession, Katelyn E. Crowell

Young Historians Conference

From its believed origin in Ancient Mesopotamia, prostitution has not only survived but is a profession that has continued to play a culturally defining role through the centuries. While its initial emergence was through an act of religious ritual and sacrifice, it transformed into a commercial profession. Prostitution, despite it becoming a representation of sexual deviance, not only persevered but thrived across vast regions, cultures, and time periods. The profession's social ‘taboo’ and the forbiddenness of being associated with the institution has carried forward through time and across varying societal constructs, the attempts to hide or extinguish prostitution has never …

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 …

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 …

Bending Moral Philosophy And Philosophy Of History Toward Each Other, Bennett B. Gilbert

History Faculty Publications and Presentations

In lieu of an abstract, here is an excerpt from the introduction:

In his journal of intimate thoughts (called The Inward Morning) written while journeying through the wildernesses of Montana, the American existentialist philosopher Henry Bugbee (1915–1999)—who had fled there from the Harvard Philosophy Department and who remains little known even in the U.S.—wrote: “Reflection, it seems, must earn the gift of the essential meaning of things past.” I think this is true, that the past is both exemplar of moral reflection and part of the substance of it. I have written a book to argue for the how and …

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

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

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 …

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 …

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 …

Addressing Climate Change Anomie In Teacher Education, Teresa Anne Fowler

Northwest Journal of Teacher Education

This research project sought to understand how preservice teachers explore their relationship with Science and confidence in teaching about climate change in Science education amid a culture of denial regarding the impact of the climate crisis. Using data from three cohorts of students in an elementary Science methods course, this paper shares the context of climate change acceptance in the province of Alberta, Canada, the fossil fuel economic hub of Canada, and how using Journell’s framework for controversial issues alongside a critical energy literacy framework using inquiry, supported preservice teachers to address their hesitancy in Science classrooms to engage with …

Creating A New Border Culture In The Midst Of The Climate Crisis: Activism And Pedagogy Strategies For Teacher Preparation, Puneet S. Gill

Northwest Journal of Teacher Education

This paper documents the efforts of an activist group that came to teach about activist efforts, climate change/climate justice/climate crisis issues, and to create leaders in one border community. The leaders of this three-day workshop are a part of an activist organization named SOMOS Sunrise, the Latine constituency of the Sunrise movement. In this paper, I will analyze the climate change workshop training days and components of the workshops. Secondly, this paper will document a climate cohort education group conducted with undergraduate students and pre-service teachers the following summer. This climate cohort helped articulate art activism and public speaking opportunities …

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 …

Chemical And Physiological Interactions Between E-Liquid Constituents: Cause For Concern?, Robert M. Strongin, Eva Sharma, Hanno C. Erythropel, Nada O F Kassem, Alexandra Noël, D H. Peyton, Irfan Rahman

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 …

Quantum Search Algorithms For Constraint Satisfaction And Optimization Problems Using Grover's Search And Quantum Walk Algorithms With Advanced Oracle Design, Abdirahman Sheikh Hassan Alasow

Dissertations and Theses

The field of quantum computing has emerged as a powerful tool for solving and optimizing combinatorial optimization problems. To solve many real-world problems with many variables and possible solutions for constraint satisfaction and optimization problems, the required number of qubits of scalable hardware for quantum computing is the bottleneck in the current generation of quantum computers. In this dissertation, we will demonstrate advanced, scalable building blocks for the quantum search algorithms that have been implemented in Grover's search algorithm and the quantum walk algorithm. The scalable building blocks are used to reduce the required number of qubits in the design. …

Co-Designing With First-Generation Transfer Students, Randi Petrauskas Harris

Dissertations and Theses

Roughly 80% of community college students indicate that they intend to transfer to a four-year institution, 30% of those students eventually transfer, and 13% of those students persist to graduate with a baccalaureate degree. There has been previous research on transfer students and on first generation students, but the intersection of first-generation transfer students is under-reported. Prior research indicates that sense of belonging is an important factor in student persistence to graduation for transfer students. Higher education institutions, specifically four-year public institutions, are positioned to support first-generation transfer student sense of belonging by fostering a "transfer receptive culture." Recognizing that …

Meso-Scale Seabed Quantification With Geoacoustic Inversion, Tim Sonnemann, Jan Dettmer, Charles W. Holland, Stan E. Dosso

Electrical and Computer Engineering Faculty Publications and Presentations

Abstract Knowledge of sub-seabed geoacoustic properties, for example depth dependent sound speed and porosity, is of importance for a variety of applications. Here, we present a semi-automated geoacoustic inversion method for autonomous underwater vehicle data that objectively adapts model inference to seabed structure. Through parallelized trans-dimensional Bayesian inference, we infer seabed properties along a 12 km survey track on the scale of about 10 cm and 50 m in the vertical and horizontal, respectively. The inferred seabed properties include sound speed, attenuation, density, and porosity as a function of depth from acoustic reflection coefficient data. Parameter uncertainties are quantified, and …

Knowledge Of Medicaid Expansion To Recent And Undocumented Immigrants Among Oregon Mexican-Origin Latinos: (Work In Progress), Nancy Ledezma, Grace Parra, Alejandra Nunez, Dr. Blair Darney

OHSU-PSU School of Public Health Annual Conference

Background

Recent and undocumented immigrants are explicitly excluded from federal Medicaid and state insurance exchanges. The first phase of Healthier Oregon was implemented in July 2022 and expanded Medicaid (OHP) benefits to undocumented immigrants ages 19-25 or 55 and older. The second phase was implemented in July 2023 and extended benefits to everyone regardless of age. We assessed understanding of Healthier Oregon among Mexican-origin Latinos. We hypothesize that many potentially eligible people may not know about the program, if they qualify, or how to apply.

Methods

This is a cross-sectional study in collaboration with the General Consulate of Mexico. Our …

What Can We Learn About Teaching Excellence From Our Students? Lessons From Six Years Of Teaching Award Data, Christopher Shortell, Kris Henning, Carl Christiansen

Political Science Faculty Publications and Presentations

Teaching excellence in higher education can be defined and studied in different ways, but research efforts to date have often focused on institutional or instructor perspectives. This article uses a data set of over 500 open-ended comments submitted by Political Science undergraduates as part of a teaching award process to identify themes that matter most to students. We find that being supportive, bringing humor, enthusiasm, and passion to the classroom, and engaging students with relevant, challenging, and exciting activities are what defines teaching excellence from a student’s perspective. Building on these themes and using quotes to illustrate key concepts, we …
