The result is a “quintalog” of the five authors in critical conversation with each other about their own reflections on the ways in which mathematics teacher educators and the …

Demagoguery And The Depression, David Horowitz

History Faculty Publications and Presentations

Taking advantage of the economic devastation wrought by the Great Depression of the 1930s, a variety of colorful personalities advanced a host of panaceas to redress the grievances of ordinary Americans. Although President Franklin D. Roosevelt, Wisconsin progressive Philip La Follette, and the Communist Party were among those on the left tainted with charges of demagoguery, the controversy over the manipulation of uninformed opinion centered on aspiring mass movement leaders such as Louisiana Senator Huey P. Long, radio priest Father Charles E. Coughlin, old-age pension advocate Dr. Francis E. Townsend, agrarian radical William Lemke, and right-wing populist Rev. Gerald L. …

A Genus In The Bacterial Phylum Aquificota Appears To Be Endemic To Aotearoa-New Zealand, Jean F. Power, Carlo R. Carere, Holly E. Welford, Daniel T. Hudson, Kevin C. Lee, John W. Moreau, Anna-Louise Reysenbach, Thijs J.G. Ettema, Multiple Additional Authors

Biology Faculty Publications and Presentations

Allopatric speciation has been difficult to examine among microorganisms, with prior reports of endemism restricted to sub-genus level taxa. Previous microbial community analysis via 16S rRNA gene sequencing of 925 geothermal springs from the Taupō Volcanic Zone (TVZ), Aotearoa-New Zealand, revealed widespread distribution and abundance of a single bacterial genus across 686 of these ecosystems (pH 1.2-9.6 and 17.4-99.8 °C). Here, we present evidence to suggest that this genus, Venenivibrio (phylum Aquificota), is endemic to Aotearoa-New Zealand. A specific environmental niche that increases habitat isolation was identified, with maximal read abundance of Venenivibrio occurring at pH 4-6, 50-70 °C, and …

Automation Of Productive Machinery. Bases For An Innovative Business Model, Carlos Guillermo Hernández-Cenzano, Angel Contreras-Cruz, Eduardo Humada-Tello

Engineering and Technology Management Faculty Publications and Presentations

Nowadays, some laboratories perform elastic properties tests for concrete or rock cores using equipment manufactured 50 years ago. The original data collection procedure uses analog and manual recordings, which can cause inaccuracies in the measurements taken during these trials The process is tedious and updated since each trial's measurement data is recorded manually. In this context, this study systematizes the process and proposes an automated data acquisition and recording system for this type of equipment, followed by a case study presenting a rock compression test.

Field Demonstration Of Residential Der Service-Oriented Load Participation, Zhongkai Zeng, Dana Paresa, Midrar Adham, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Amidst a concerning surge in power consumption during peak hours, coupled with heightened power grid instability, and driven by a growing demand for electricity, aggregations of Distributed Energy Resource are becoming a viable means for providing essential reliability services. Electric utility companies have proactively implemented Demand Response programs for decades. These programs employ Direct Load Control methods to enhance power grid stability, achieved by controlling customers’ Distributed Energy Resource during peak hours to reduce power consumption. However, a notable drawback of Direct Load Control has been high unenrollment rates of DR program participants due to customer discomfort. Therefore, the underlying …

Trust Model Utilization For Energy Grid Communication, N. Sonali Fernando, John M. Acken, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

The internet information that is used by the Energy Grid of Things requires both preventative security measures as well as surveillance measures. The preventative security measures include certificates, encryption, and all of the basic security protocols as defined by published standards. The surveillance measures include monitoring information flow activities and evaluating these messages for indications of potential security attacks. We describe in this paper the utilization of a Distributed Trust Model that was developed specifically for monitoring communication within an Energy Grid of Things. The goal for the Distributed Trust Models is to provide a level of aggregate trust that …

Unjust And Unsafe: The Eviction Experiences Of Latine Immigrant And Farmworker Tenants In Oregon, Natalie J. Cholula, Lisa K. Bates, Alex Farrington, Marisa Zapata, Jacen Greene, Azad Amir-Ghassemi, Colleen Carroll

Sociology Faculty Publications and Presentations

Latine immigrant households often face housing instability due to language barriers, immigration status, and limited access to government resources. Oregon farmworkers experience additional obstacles to safe and stable housing caused by low wages, a lack of affordable housing options, and social isolation. In light of the identified needs and lack of equitable access to resources that this group experiences, the Evicted in Oregon research team conducted focus groups with Latine immigrant and farmworker tenants in Multnomah, Washington, and Marion Counties. The aim was to gain insight into their experiences with eviction and understand how they navigated through evictions during the …

Deep Adaptive Graph Clustering Via Von Mises-Fisher Distributions, Pengfei Wang, Daqing Wu, Chong Chen, Kunpeng Liu, Yanjie Fu, Jianqiang Huang, Yuanchun Zhou, Jianfeng Zhan, Xiansheng Hua

Computer Science Faculty Publications and Presentations

Graph clustering has been a hot research topic and is widely used in many fields, such as community detection in social networks. Lots of works combining auto-encoder and graph neural networks have been applied to clustering tasks by utilizing node attributes and graph structure. These works usually assumed the inherent parameters (i.e., size and variance) of different clusters in the latent embedding space are homogeneous, and hence the assigned probability is monotonous over the Euclidean distance between node embeddings and centroids. Unfortunately, this assumption usually does not hold since the size and concentration of different clusters can be quite different, …

Housing Choice, Transportation Equity, And Access To Opportunities In Refugee And Immigrant Communities, Diane Mitschke, Anne Nordberg, Stephen Mattingly, Katherine Kitchens

TREC Final Reports

Mobility directly impacts access to opportunities for all protected classes; however, transportation planning and public transit agencies and housing authorities rarely coordinate affordable housing and the transportation system planning decisions. This lack of coordination often leads to mismatches between access to opportunities and affordable housing. Safe access to employment, quality schools, and healthcare represent a few of the many factors that may influence housing choice. For most households with budget constraints, all of these factors may not be achievable. While existing research documents the mismatch between affordable housing and access to opportunities, the role that mobility plays in residential selection …

Fight, Flight, Freeze: How Access To Support Shapes Tenant Responses To Eviction In Multnomah County, Natalie J. Cholula, Lisa K. Bates, Alex Farrington, Marisa Zapata, Colleen Carroll, Jacen Greene, Hadley Bates

Urban Studies and Planning Faculty Publications and Presentations

Facing eviction is a traumatic event that forces tenants into a fight, flight or freeze response. Our focus groups with Multnomah County tenants reveal that their responses to eviction are directly shaped by their access to support. Many tenants are unable to access formal support and therefore respond to eviction by freezing up or fleeing their home. Conversely, tenants who can access formal support—including rental assistance or legal assistance—exhibit a fight response, leveraging external support to challenge or avoid their eviction.

Targeted, Harassed, And Displaced: The Role Of Discrimination In Oregon Evictions, Alex Farrington, Natalie J. Cholula, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

Drawing on focus groups with 101 Oregon tenants who have experienced an eviction since the onset of the COVID-19 pandemic, this report examines the role that discrimination plays in Oregon evictions. As this is not a legal investigation, we do not focus solely on legally-actionable or provable claims. Rather, we include a wide range of tenants’ descriptions of their experiences with unfair, malicious, or prejudicial treatment. We find that many tenants are specifically targeted for eviction or experience prejudicial treatment during the eviction process because of their identity or background. This includes being treated unfairly based on tenants’ race, language, …

Suitability Analysis Of Public And Institutional Lands For The Oregon Farm To Institution Collaborative, Megan Horst, Maura Paxton

Urban Studies and Planning Faculty Publications and Presentations

The goal is to assist the Oregon Farm to Institution Collaboration, and particularly the Land Access and Shared Assets Work Group, in identifying possible lands for farmers and food producers to grow food for schools, hospitals, and other institutions.

We start by comparing Oregon to other states, in terms of their public land access efforts around farm to institution or other related agriculture. We also showcase some interesting cases which may serve as inspiration to Oregonians. The …

Shame And History, Bennett B. Gilbert

University Studies Faculty Publications and Presentations

If history—our past, the sum of our thoughts, passions, and deeds—is so pervasive, influential, and meaningful, why then do we lose sight of it? Why do we not gain good values from it? And if it is part of our existential core, why then do we so often fail to ravel it into our deliberations?

I propose that very often and to a great degree it is shame that separates us from history. Shame: garrulous, compulsive, intense, omnivorous. A shamed person pushes away the experiences that shame her, thus cutting off the past.

Including Voices And Mitigating Bias: Evaluative Practices For Final Interviews, Xan Arch, José Velazco

Library Faculty and Staff Publications and Presentations

The chapter discusses the preparation of non-search committee members to participate in an interview process and provide feedback on candidates. Increasingly, as our institutions strive for more inclusive search processes, we are incorporating equitable hiring practices such as implicit bias training for search committee members, rubrics for evaluating candidate applications, and behavior-based interview questions. However, for final interviews, we often throw the door open for general evaluation of candidates by a broad group of people who agree to attend a meeting, presentation, or meal. The feedback we gain from these final interview events may truly be germane to the candidates’ …

University Studies Research Brief: Winter 2024 Frinq Faculty Student Persistence Survey, Rowanna L. Carpenter

University Studies Assessment Research

Of 1285 students enrolled in First-year Inquiry (FRINQ) during fall term 2023, 161 (13%) received an F, W, or I grade in FRINQ and/or did not return to PSU during winter term. In order to better understand why these students struggled or did not return, FRINQ faculty were surveyed about the students in their courses who received an F, W, or I grade in their fall term FRINQ and/or did not return to PSU for winter term. For each student, faculty were asked to identify specific challenges the student may have faced and any support they knew the student had …

University Studies Capstone Community Partner Feedback Spring 2024, Rowanna L. Carpenter, Seanna Kerrigan

University Studies Assessment Research

Since 1995, Portland State University has offered students the opportunity to engage in the community as the culmination of their general education experience through Capstones, community-engaged courses, each of which has a community partner. For several years after the beginning of the program, community partners were asked for their feedback. However, over time, response rates declined and the collaborating office was reorganized, so the practice was discontinued. During Winter 2024, University Studies (UNST) implemented a revised survey to seek feedback from current partners. Thirty-six respondents from twenty-five community partners (representing approximately 75 Capstones and thus half of UNST 421 Capstones) …

Developmental Change In English-Learning Children’S Interpretations Of Salient Pitch Contours In Word Learning, Carolyn M. Quam, Daniel Swingley

Speech and Hearing Sciences Faculty Publications and Presentations

To efficiently recognize words, children learning an intonational language like English should avoid interpreting pitch-contour variation as signaling lexical contrast, despite the relevance of pitch at other levels of structure. Thus far, the developmental time-course with which English-learning children rule out pitch as a contrastive feature has been incompletely characterized. Prior studies have tested diverse lexical contrasts and have not tested beyond 30 months. To specify the developmental trajectory over a broader age range, we extended a prior study (Quam & Swingley, 2010), in which 30-month-olds and adults disregarded pitch changes, but attended to vowel changes, in newly learned words. …

Analyzing Frequency Event Detection Algorithm Performance Using Different Denoising Methods, Hussain A. Alghamdi, Midrar Adham, Robert Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Maintaining grid frequency at its nominal value is crucial for power system stability and supply-demand balance. Swift and accurate detection of frequency events is vital for providing primary frequency response support. Frequency event detection algorithms often rely on Phasor Measurement Unit data, which may contain noise. Implementing a denoising preprocessing step enhances detection precision and accuracy. In previous works, a frequency event detection algorithm based on wavelet transform was developed, which uses discrete wavelet transform (DWT) for denoising purposes. In this paper, several denoising techniques are considered as potential replacements for the current DWT method. This research investigates and compares …

Salvation And Sweet Rolls: An Examination Of Mormon Diet Books, Rachel Noorda

English Faculty Publications and Presentations

Religious diet books highlight the overlap between religious and diet cultures. This article examines the intersection of Mormonism, diet culture, and fatphobia through an analysis of Mormon diet books published between 1990 and 2015. The study explores how Mormon diet books leverage the Word of Wisdom (the LDS health code) to promote weight loss and reinforce religious obedience. By framing dietary compliance as a spiritual mandate, these texts link physical health and body size to moral and spiritual worthiness. This conflation of body and spirit, rooted in Mormon theology, amplifies fatphobia by promoting thinness as a sign of obedience and …

International Bestsellers And The Online Reconfiguring Of National Identity, Rachel Noorda, Millicent Weber, Melanie Ramdarshan Bold

English Faculty Publications and Presentations

International bestsellers are the ideal sites for examining the complicated relationship between literary culture and national identity. Despite the transnational turns in both literary studies and book history, place is still an important configurer of twenty-first-century book reception. Books are crucial to national identity and catalysts of nationalist movements. On an individual level, books enable readers to shape and maintain their own national identities. This Element explores how contemporary readers' understandings of nation, race/ethnicity, gender, and class continue to shape their reading, using as case studies the online reception of three bestseller titles-Liane Moriarty's Big Little Lies (Australia), Zadie Smith's …
