The Rise Of Xr Storytelling And The Contribution Of Consumer Accessibility, Cost Efficiency, & Intrinsic Value To Feasibility, Sarah Moffatt

Book Publishing Final Research Papers

This research assesses the current state of XR (extended reality) publishing and its feasibility within an exceptionally virtual landscape. Feasibility is measured upon the challenges and opportunities posed by accessibility, cost efficiency, demand, and intrinsic value.

Through market analysis of past and ongoing XR storytelling projects, as well as qualitative methods which include industry interviews and public surveys, it has been found that publishers would do well to first adopt augmented reality storytelling methods before venturing further into virtual reality storytelling. Because augmented reality is generally more accessible and cost efficient, its adoption contributes to increased …

The Impact Of Targeted Regulation Of Abortion Providers Laws On Abortions And Births, Grace E. Arnold

Economics Faculty Publications and Presentations

This paper analyzes the impact of supply-side abortion restrictions on aggregate abortion and birth rates in the USA. Specifically, I exploit state and time variation in the implementation of the first targeted regulation of abortion provider (TRAP) law in a state to identify the effects of the laws. I find that TRAP laws are associated with a reduction in the abortion rate of approximately 5% the year the first law is implemented, and an average reduction of 11–14% in subsequent years. There is also evidence that TRAP laws increased birth rates by 2–3%, which accounts for approximately 80–100% of the …

Implementing an OER curriculum can result in benefits that go far beyond controlling costs for students, which is itself a significant step toward improving equity. Drawing on your own experience and expertise as language educators, as well as the contributions of collaborators around the world, it is possible to build a curriculum customized for your unique student group. With thoughtful design, your program can help students achieve desired learning outcomes not just in language acquisition, but also in diversity, equity, and inclusion (DEI). In this talk, I will …

Inclusive Approaches For Measuring Demographics Of Underrepresented Populations In Stem And Biomedical Research Training Programs, Stephanie E. Paris, Teala W. Alvord, Brandy Lentz, Mollie C. Marr, Angie Setthavongsack, Alexis Dinno, Jae Downing, Aaron Raz Link, Dawn M. Richardson, Shanthia N. Espinosa, Phuc T. Nguyen, Lisa K. Marriott

Student Research Symposium

Federal strategic plans call for increased diversity within the biomedical workforce. The National Institutes of Health (NIH) defined underrepresented populations in biomedical science (NOT-OD-20-031), though operationalization remains a challenge for training programs. Implementing inclusive demographic measures may help to identify key demographic groups facing barriers to participation and retention in STEM programs and the biomedical workforce. Approaches for measuring demographic variables were sourced from scientific literature and research stakeholders. Gender, race/ethnicity, disability, and disadvantaged background were prioritized for comparison given their focus by NIH, with opportunities for stakeholders to identify additional demographic variables important in their work. Gender minorities, sex …

Family On Film Post-World War Ii Japan: Kurosawa And Ozu, Alexander J. Ham-Kucharski

Student Research Symposium

The Post World War II films of Akira Kurosawa (1910-1998) and Yasujiro Ozu (1903-1963) share a traditional trope of what is constituted as family in United States Occupied Japan (1945-1952), and their films transcend their production year to still illustrate a Japan of the 21^st century. By studying what is “family” in Rashomon, The Seven Samurai, Late Spring, and Tokyo Story, we see family is defined not only in a traditional Japanese sense, but also the the audience, film student, and critic can see how Kurosawa and Ozu extended the idea of family into community, politics, military, …

Dual Colonization Of Okinawa: Gendered And Militarized Violence, Katie Y. Hashimoto

Student Research Symposium

Off the southern part of Japan is the small archipelago of Okinawa. Making up only 0.6% of Japan’s total land mass, Okinawa hosts 74% of the nation’s U.S. military bases. Since World War II, the U.S. military has grown a dominating presence on the islands, inevitably influencing the lives of the locals. A portion of Okinawans have since been protesting for the removal/reduction of these bases through what is known as the Anti-Base Movement but have been largely ignored by the governments of Japan and the U.S. At first glance, these protests seem to be centered around environmental issues, land …

Barriers And Supports For Stem Motivation For Pacific Islander High School And Undergraduate Students, Shanthia N. Espinosa, Alma M. O. Trinidad, Lisa K. Marriott

Student Research Symposium

Pacific Islander (PI) students disproportionately come from low socioeconomic backgrounds and are often first-generation college students. PI students have been historically underserved with limited access to educational resources and support. As a result, PI students face low student retention rates and have reported dissatisfaction with higher education student services. There is little research dedicated to understanding the STEM experiences of PI students related to access, success, and motivational resilience in higher education. This study examines barriers and facilitating factors for motivation among PI students using electronic surveys, focus groups, and group discussions. Participants comprise high school and undergraduates residing in …

Film History Digests, Nathan A. Varner

Student Research Symposium

Film History Digests is a web series created by Nathan Varner and chronicled popular culture's smaller and underrepresented parts. This project showcased collaboration, innovation, consistency, and determination for a small team. In return, we uncovered the decades-long mystery, shined a light on mental health, and provided a subtext of non-partisan political discourse all over a year.

Farmworker Voices: Contesting & Renegotiating Essential Status During The Covid-19 Pandemic, Jennifer Martinez

Student Research Symposium

This study draws on a subset of thirty individuals that took part in the community-driven Oregon COVID-19 Farmworker Study to analyze how farmworkers interpreted the contradictory label essential worker. Using discourse analysis, this article examines how these peasant workers drew on their embodied experiences working throughout the pandemic to give meaning to their essential designation. The data suggest that farmworkers were tacitly aware of the contradictions between their labeling as indispensable and their disposable treatment on the ground. Farmworkers generally felt unrecognized, underpaid, and felt exposed to COVID-19 infection in addition to everyday workplace hazards. While the essential title was …

Disentangling The Nazis And The Vikings, Arden Goldberg

Student Research Symposium

In the development of nationalism, and specifically white ethnonationalism, the Norse have played an unfortunate role, and one that deserves a closer interrogation. In the larger scheme of white nationalism, those who seek to directly appropriate Norse symbology and a reconstruction of their own ideal of Norse culture are a relative minority, but they remain a minority which taints the study of Norse history. In this talk, I will examine how Norse symbology and identity has come to be appropriated by white nationalists, compare the racist perceptions of the Norse with knowable historical realities, explain the usefulness of Norse symbology …

Social Capital And Cross-Boundary Collaboration In Wyoming Wildfire Management Networks, Hannah L. Spencer, Christian Heisler

Student Research Symposium

Wildfire hotspots often intersect jurisdictional boundaries, so protecting human communities and restoring healthy fire regimes will require collaborative, cross-boundary action from fire managers. However, collaboration between fire management groups can have varied outcomes depending on the actors involved, all with different missions, financial obligations, and cultures. One way to conceptualize the interactions between actors is with the idea of social capital. We will investigate the following research question: how does social capital impact cross-boundary collaboration in wildfire management networks? We will survey wildfire managers in northwestern Wyoming about their collaborative actions using a snowball sampling method. Using Social Network Analysis …

Investigation Of The Externship Selection Process Across Asha-Accredited Speech Language Pathology Programs, Teale Niles, Lindsey Schwab, Brandon Eddy

Student Research Symposium

Graduate students in speech-language pathology (SLP) must complete 400 clinical clock hours during graduate training, the majority of which frequently come from off-campus externship experiences. Graduate students are matched to externship sites by their program. No studies to date have systematically documented how graduate programs in speech-language pathology select students for externship experiences nor the constraints involved in the externship process (e.g., academic schedule). The goal of this study is to survey ASHA accredited SLP programs to describe the current procedures being used to place students at externship sites and the roles and perspectives of the externship coordinators. Externship coordinators …

Comparison Of Heavy Metals In Spinach Grown On The Roof Ground Location At Portland State University, Tyler A. Robin

Student Research Symposium

As a result of urbanization, fresh, healthy food can be expensive and easily contaminated but space for local farming is limited. Roofs can be underutilized in densely populated cities and can offer a space for local fresh farming. The purpose of this study is to continue a previous study done in 2021, to find if growing leafy vegetables on the roof can limit heavy metal exposure from air pollutants. This study compares spinach grown on the roof in 2021, 2019 and spinach bought from stores around the Portland State University campus and the heavy metals found in these greens. The …

Surface Plasmon Characterization In Ag Nanotriangles For Evaluation Of Fano Resonance Conditions, Nabila Islam

Student Research Symposium

Surface plasmon polariton (SPP) is a collective oscillation of electrons and light at the metal -dielectric interface excited by the incident radiation on metal surface through the momentum matching conditions. The properties of SPPs and the resonance conditions are highly dependent on the confining materials and geometry of the confining nanostructure. The sensitivity of the surface plasmon resonance to the property of the confining materials made Surface plasmon resonance (SPR) sensors a central tool for biosensing. However, the frequency resolution of SPR sensors is typically limited by the broad resonance of the SPR mode. The resolution can be enhanced through …

Augmentative And Alternative Communication Course Design And Features: An Analysis Of Course Syllabi And Calendars, Celine Goodbody, Hosanna Broderick, Brandon Eddy

Student Research Symposium

Augmentative and alternative communication (AAC) is an area of clinical practice that supplements or compensates for impairments in speech-language production and/or comprehension (ASHA, n.d.). A survey study by Johnson and Prebor (2019) found 86% of graduate speech-language pathology (SLP) programs offered an AAC course, though half (49%) suggested their students were underprepared to provide AAC services. High-quality graduate training, including AAC coursework, has been suggested as a solution to prepare clinicians to provide AAC services. Recently, Sauerwein and Burris (2021) surveyed AAC course instructors at accredited SLP graduate programs to analyze AAC course design features. Sixty-four (24.2%) programs responded to …

Memristors, Memcapacitors And Their Application In Neuromorphic Computing, Nithyakalyani Sampath

Student Research Symposium

Data-intensive computing operations, such as training neural networks, are essential but energy-intensive. Memcapacitance and memristance,which can be described as capacitance and resistance, with “memory”, are properties of semiconductor devices that are observed on the nano-scale. These properties allow for data storage without a constant source of power, leading to hardware which is more energy efficient.

We intend to demonstrate that we can build specialized hardware onto which a neural network can be directly mapped using memristors and memcapacitors, improving the energy efficiency of the network. We will use Simulation Program with Integrated Circuit Emphasis (SPICE) to model our memcapacitor and …

Characterizing The Functional Role Of Transcription Factor E In Archaeal Transcription, Madolyn Hofstetter, Michael Bartlett

Student Research Symposium

Archaea and eukaryotes share many homologous proteins and essential mechanisms for survival and DNA replication. It is proposed that Archaea are the ancestors of eukaryotes, suggesting that eukaryotic transcription evolved from the basic archaeal mechanisms. By studying the fundamentals of archaeal transcription, we are in turn understanding more about how eukaryotic transcription functions. Many human diseases are linked to mishaps and mutations in the process of transcribing DNA to mRNA, so it is essential to explore structures and how mutations in these structures affect the essential function of transcription, and if these mutations also play a role in human disease.

Sharpton, Eddie Niwed, Lisa K. Marriott

Student Research Symposium

I will be speaking about our ongoing project with OHSU and Mae Fah Luang University about the effects of a highly fibrous rice called “Sin Lek” and the changes it will do to both the gut microbiome and cognitive function. My data analysis focuses solely on memory, attention span, and impulsivity on Thai schoolchildren. The poster will document baseline data and it’s outcomes, along with brief information about Dr. Siam Popluechai’s lab findings on certain microbiome species. I will also be going in depth about the area of the study, along with how these were tested such as explaining the …

Visualization Of Eye Development In Annual Killifish Using Whole-Mount Immunohistochemistry, Carmen Z. Rodriguez, Jason Podrabsky

Student Research Symposium

Vertebrate eye development is highly conserved. Current models have identified the gene networks involved in eye development, but lack the context of extreme environmental conditions that challenge these fundamental programs. Typical vertebrates live for many years while annual killifishes can complete their entire adult lifespan in a matter of weeks. Thus, annual killifishes are a strong model for age-related diseases such as age-related macular degeneration (AMD); an irreversible loss of central vision. Annual killifishes enter embryonic diapause; a period of developmental and metabolic dormancy. These embryos are extremely resistant to environmental stresses such as hypoxia/anoxia that would cause irreparable damage …

Growing Reservoir Networks Using The Genetic Algorithm Deep Hyperneat, Nancy L. Mackenzie

Student Research Symposium

Typical Artificial Neural Networks (ANNs) have static architectures. The number of nodes and their organization must be chosen and tuned for each task. Choosing these values, or hyperparameters, is a bit of a guessing game, and optimizing must be repeated for each task. If the model is larger than necessary, this leads to more training time and computational cost. The goal of this project is to evolve networks that grow according to the task at hand. By gradually increasing the size and complexity of the network to the extent that the task requires, we will build networks that are more …

Survey Of The Bees And Floral Use At The Leach Botanical Garden, Joshua Page

Student Research Symposium

There have been few studies of the diversity of bee species found in Oregon’s urban areas, and fewer studies that have systematically examined how bee populations change over the seasons. A survey of native bee populations at the Leach Botanical Gardens was conducted to determine what bees were present, how they changed over the season, and what flowers they used. Biweekly over the 2020 and 2021 bee seasons, sections of the garden were sampled in 30 minute equal time intervals, divided among the patches of flowering plants on which bees were observed. Bee specimens were captured with collection vials on …

Mapping Ecosystem Service Flows Of Estuary Restoration Projects On The Oregon Coast To Identify Impacted Stakeholders, Shersten Finley

Student Research Symposium

Restoration of largely depleted estuarine systems is increasingly recognized as key to solving a variety of problems coastal communities face currently. Many of these issues will become more acute with climate change and sea level rise. Historic losses of estuary area, and recognition of the ecosystem services provided by functioning estuary ecosystems have resulted in current impetus to pursue estuary restoration. By mapping the flows of ecosystem services using three ecosystem service ‘scorecard’ categories pertaining to coastal resource management: recreation, aesthetics, and cultural/historical/spiritual, we gain a better understanding of the populations impacted by the changes in flows of ecosystem service …

Simple Arenes As Aryne Synthetic Equivalents Via Sulfonium Salt Intermediates, Riley A. Roberts

Student Research Symposium

Arynes are ephemeral molecules that are yet to be fully exploited in synthetic strategy because they are often challenging to access. These reactive intermediates participate in a myriad of reactions that conventional chemistry is incapable of, making them extremely useful for the synthesis of important molecules like pharmaceuticals and agrochemicals. While classical approaches for synthesizing arynes employ cheap starting material, extremely harsh reagents are necessary to generate the aryne. In contrast, methods that do not require harsh reaction conditions do require starting material that is exceedingly difficult to synthesize. To access arynes quickly and efficiently, the work described herein aims …

Third-Wave, Mindfulness-Based Therapies As Treatments For Obsessive-Compulsive Disorder: A Randomized Controlled Trial, Xander Kahle, Avery Waklatsi, Amy Pytlovany

Student Research Symposium

Obsessive-compulsive disorder (OCD) is a severe, difficult-to-treat neuropsychiatric condition that affects millions of people throughout the world. The current first-line psychotherapy for OCD is exposure and response prevention (ERP). ERP is effective but flawed, and researchers seek alternative OCD treatments. We examined two third-wave, mindfulness-based therapies (1) acceptance and commitment therapy (ACT) and (2) mindfulness-based cognitive therapy (MBCT) as treatments for OCD. We expected ACT/MBCT to have (1a) significantly higher OCD symptom reduction rates, (1b) higher treatment response rates, and (1c) lower dropout rates than a control (progressive relaxation training/PRT), as well as (2a) equal/higher OCD symptom reduction rates, (2b) …

Understanding Work And Sleep Through A Machine Learning Approach, Jennifer Saucedo, Josh J. Prasad, Tori L. Crain

Student Research Symposium

The present study will utilize machine learning methods to find the individual factors (e.g, demographic, lifestyle, contextual, work-related) best predict sleep. I will examine (1) whether machine learning techniques better predict sleep over linear prediction methods and (2) what factors are most important when predicting sleep. Using government-funded data from the Bureau of Labor Statistics (BLS), a variety of prediction methods will be utilized to evaluate and compare predictive performance across 2018, 2019, and 2020. Results found will have a variety of theoretical and practical implications for scientists and practitioners.

The Effects Of Approach And Avoidance Dispositions And Sense Of Power On Promotive And Prohibitive Voice Efficacy, Christopher J. Waterbury, Avery N. Waklatsi, Amy Pytlovany Ph.D.

Student Research Symposium

Developments in research on promotive and prohibitive voice in workplaces have important implications for organizational innovation and prevention of unethical behavior. Drawing on theory that approach and avoidance dispositions predict promotive and prohibitive voice, and mediate the effect of a sense of powerfulness or powerlessness to predict voice or silence, the proposed study hypothesizes that approach and avoidance disposition will explain differential effects of personal sense of power on an employee’s perceived efficacy of promotive and prohibitive voice. 200 front-line restaurant workers will be recruited and randomly assigned to receive a (1) powerful prime, (2) powerless prime, or (3) control …

Case Study In Activist Applied Linguistics: Working With The Oregon Judicial Department For The Accessibility Of Domestic Relations Information, Amandalyn R. Wayland, Jamal R. Ford, Abbee A. Mortensen

Student Research Symposium

How are students of applied linguistics able to contribute to community efforts in increasing access to justice? Activist applied linguistics (AAL) (Cowal & Leung, 2021) is defined as utilizing applied linguistics in coordination with community partners to address wicked problems (Rittel & Webber, 1973). AAL provides a framework for engaging university students with communities outside of their campus and has been utilized to further work in water justice (Haeffner & Cowal, 2019) and to increase the Oregon State Bar website’s comprehensibility (Anesa, Cowal, & Pulju, 2022). In this poster, we present an AAL case study in which students of applied …

Implicit Learning In Preschoolers With Developmental Language Disorder, Crystal L. Cairns, Sam Ward, Emma Duran, Molly Franz, Carolyn Quam

Student Research Symposium

We compared implicit learning in preschoolers with and without developmental language disorder (DLD), to test the procedural deficit hypothesis (PDH), which proposes that implicit learning is the core impairment in DLD. During the first experiment we tested 26 preschoolers with typical language development (TLD) and 26 preschoolers with DLD. Eligibility was determined through standardized assessment. We predicted children with DLD would show impairments in a test of implicit learning.

Using computer-based tasks, participants received training on sound discrimination in two dimensions: duration and pitch.They were tested on their ability to accurately categorize these two dimensions by mapping sounds to meaning. …
