Holistic Methodologies For Fusing The Material And The Ideological: Tracing The Sociotechnical Imaginaries That Enable The World’S Fastest Supercomputer, Sarah Read, Jordan Firth

English Faculty Publications and Presentations

When the Aurora supercomputer launches at Argonne National Laboratory it will operate at the exascale and be one of the fastest supercomputers in the world. We have been invited by Argonne to do field work to understand both the day-to-day processes that maintain supercomputing (e.g. user documentation, government reporting, user testing) and the sociotechnical national imaginaries [11], –in particular the increasingly tense global competition between the US and China in the supercomputing race–that shaped the development of Aurora. This article proposes our work-in-progress methodological approach that accounts for both higher-level imaginaries and the everyday practices of supercomputing. We also describe …

The Hydraulically Smooth Limit Of Flow Over Surfaces With Spanwise Heterogeneity, Haosen Xu, George Ilhwan Park, Xiang Yang, Xiaowei Zhu

Mechanical and Materials Engineering Faculty Publications and Presentations

Wall slip is conventionally obtained through riblets or grooves. As riblets are macroscopic objects, it is usually not practical to discuss slip patterns at the hydraulically smooth limit. Per Nikuradse, the smooth limit is when the characteristic length of the surface pattern is comparable to the viscous length scale. Recent studies show the possibility of slip at the microscopic scale, making slip patterns at the hydraulically smooth limit relevant. In this study, we leverage a high-fidelity pseudo-spectral code and study flow over surfaces featuring alternating strips of slip and no-slip wall conditions. The wavelength of the surface pattern, denoted as …

The Sphere Of Exposure: Centering User Experience In Community Science Air Monitoring, Marisa Westbrook, Valentina Serrano-Salomón, Jay Pecenka, Sumit Sankhyan, Aniya K. Hollo, Shelly L. Miller, Esther Sullivan

OHSU-PSU School of Public Health Faculty Publications and Presentations

Community science has increased in popularity in communities where residents hope to investigate the relationship between environmental issues and personal health. This study partnered with neighborhoods in the most polluted residential zip code in the US to conduct community science air quality monitoring. We conducted 60 semi-structured interviews after two monitoring deployments to understand participants’ subjective experiences of pollution exposure, their engagement with low-cost air quality monitors, and their data interpretation. We utilize the environmental health concept ‘exposure experience’ to analyze how participants use personal monitors, understand their data, and reinterpret their pollution exposure as a result. We further explore …

The Integrated Violin-Box-Scatter (Vbs) Plot To Visualize The Distribution Of A Continuous Variable, David W. Gerbing

Business Faculty Publications and Presentations

The histogram remains a widely used tool for visualization of the distribution of a continuous variable, despite the disruption of binning the underlying continuity into somewhat arbitrarily sized discrete intervals imposed by the simplicity of its pre-computer origins. Alternatives include three visualizations, namely a smoothed density distribution such as a violin plot, a box plot, and the direct visualization of the individual data values as a one-dimensional scatter plot. To promote ease of use, the plotting function discussed in this work, Plot(x), automatically integrates these three visualizations of a continuous variable x into what is called a VBS plot here, …

“What Keeps Me In School”: Oregon Bipoc Learners Voice Support That Makes Higher Education Possible, Roberta Hunte, Miranda Mosier-Puentes, Gita Mehrotra, Eva Skuratowicz

School of Social Work Faculty Publications and Presentations

A growing number of college students are nontraditional learners (age 21–65) who are people of color. These students face unique challenges in a higher education system increasingly shaped by neoliberalism and the ongoing context of institutionalized racism. In Oregon, policymakers have established ambitious goals to address racial disparities in educational attainment. In this study, focus groups and interviews were conducted with 111 Black, Indigenous, and People of Color (BIPOC) adult learners in Oregon to better understand their perspectives and experiences in regard to educational and career pathways. Participants included currently enrolled students, adults who had enrolled and left, and adults …

Far-Right Monologues And Extreme Identity, Benjamin Alexander Thigpen

Dissertations and Theses

My thesis is focused on the American far-right, by way of two sperate case studies, one centered on a contemporary movement (the manosphere) and one that has fallen from prominence (racist skinheads). Grounded in primary source analysis, my thesis builds off of the work of social movement theorists such as Sidney Tarrow, scholars of American politics like Richard Hofstadter, and emergent theories of social identity as laid out by Judith Butler and others. Through my analysis, I develop two theoretical arguments: first, that there are two distinct categories amongst far-right narratives (which I term offensive and defensive); and second, that …

Liu, Jakob L. Fischer, Jeremiah A. Alt, Todd E. Bodner, Naweed I. Chowdhury, Anne E. Getz, Peter H. Hwang, Adam J. Kimple, Timothy L. Smith, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Introduction Cystic fibrosis (CF) is commonly complicated by chronic rhinosinusitis (CRS). Despite highly effective management options, CRS in people with CF (PwCF+CRS) may be refractory to medical therapy, eventually requiring endoscopic sinus surgery. The impact of sinus surgery on pulmonary, quality of life (QOL), and other outcomes in PwCF+CRS in the expanding era of highly effective modulator therapy has not been fully elucidated. This study aims to determine if endoscopic sinus surgery can offer superior outcomes for PwCF+CRS when compared to continued medical treatment of CRS. Methods and analysis This multi-institutional, observational, prospective cohort study will enroll 150 adults with …

Fostering Resilience: Community Radio And Disaster Communication In Odisha, India, Manas Kumar Kanjilal, Kanchan K. Malik, Priya Kapoor

International & Global Studies Faculty Publications and Presentations

Local voices carry tremendous weight during natural disasters, yet the possibilities for employing participatory communicative practices for disaster management in India have not been fully explored. Effective community-centred disaster communication garners participation in disaster management processes that reduce vulnerabilities. This paper examines how various community-based organisations used community radio to enhance community engagement and the effectiveness of the disaster management processes in the eastern Indian state of Odisha. The research relies upon case studies of disaster communication practices of two community radio stations during the ‘very severe cyclonic storm’ Yaas, which made landfall in Odisha. It describes the conceptual shift …

Speech and Hearing Sciences Faculty Publications and Presentations

Background:

Aphasia, resulting from acquired brain injury, disrupts language processing and usage, significantly impacting individuals’ social communication and life participation. Given the limitations of traditional assessments in capturing the nuanced challenges faced by individuals with aphasia, this study seeks to explore the potential benefits of integrating multimodal communication elements into discourse analysis to better capture narrative proficiency in this population.ObjectiveThis study examined how incorporating multimodal communication elements (e.g., physical gestures, writing, drawing) into discourse analysis may affect the narrative outcomes of persons with aphasia compared to those observed using methods that exclude multimodal considerations.

Methods:

Participants included individuals with chronic …

Historical Redlining, Contemporary Gentrification, And Severe Maternal Morbidity In California, 2005-2018, Xing Gao, Rachel Morello-Frosch, Amani M. Nuru-Jeter, Jonathan M. Snowden, Suzan L. Carmichael, Mahasin S. Mujahid

OHSU-PSU School of Public Health Faculty Publications and Presentations

Importance Historically redlined neighborhoods may experience disinvestment, influencing their likelihood of gentrification, a process of neighborhood (re-)development that unequally distributes harms and benefits by race and class. Understanding the combined outcomes of redlining and gentrification informs how the mutually constitutive systems of structural racism and racial capitalism affect pregnancy outcomes. Objective To examine if historical redlining and contemporary gentrification is associated with increased severe maternal morbidity (SMM) odds. Design, Setting, and Participants This cross-sectional study used data from a statewide population-based sample of all live hospital births at 20 weeks’ gestation or more between 2005 and 2018 in California. Analysis …

Reporting Gunshots: Prevalence, Correlates, And Obstacles To Calling The Police, Kris Henning, Joshua Carmony, Somalia Johnson Calloway, Christian Peterson

Criminology and Criminal Justice Faculty Publications and Presentations

Accurately documenting where and when firearms are discharged is a critical first step in gun violence prevention. Many cities rely on police calls for service as their primary source for this information. Recent studies find, however, that citizens underreport gunshots. This has led some communities to invest in gunshot detection technology (GDT) as an alternative data source. GDT remains an expensive and often controversial solution with limited evidence for long-term benefits. This underscores the need for additional research on third-party reporting of gunshots. The current study, conducted in Portland Oregon, surveyed 1,240 residents in 23 neighborhoods with above-average firearm discharges. …

Exploring The Relationship Between Covid-19 Transmission And Population Mobility Over Time, Tanmoy Bhowmik, Naveen Eluru

Civil and Environmental Engineering Faculty Publications and Presentations

This study explores the dynamic relationship between COVID-19 transmission and transportation mobility, with an emphasis on understanding the time-varying bidirectional interplay across the different phases of the pandemic. To gain insight into this relationship, we analyzed county-level data on transmission and mobility patterns from the United States over a 74-week period using a comprehensive list of factors including: temporal factors, socio-demographics, health indicators, health care infrastructure attributes, and spatial factors. For our analysis, we proposed a simultaneous econometric model system that explicitly accounts for the bidirectional relationship between COVID-19 transmission and mobility patterns while also accounting for the influence of …

Housing Instability Patterns Among Low-Income, Urban Black Young Adults In California And Associations With Mental Health Outcomes: Baseline Data From A Randomized Waitlist-Controlled Trial, Michelle K. Nakphong, D. Jovon Bright, Ala Koreitem, A. Rain Mocello, Nadra E. Lisha, Hannah H. Leslie, Itzel Estrada, Margaret K. Libby, Sheri A. Lippman, Marguerita A. Lightfoot

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Deep-rooted racial residential segregation and housing discrimination have given rise to housing disparities among low-income Black young adults in the US. Most studies have focused on single dimensions of housing instability, and thus provide a partial view of how Black young adults experience multiple, and perhaps overlapping, experiences of housing instability including homelessness, frequent moves, unaffordability, or evictions. We aimed to illuminate the multiple forms of housing instability that Black young adults contend with and examine relationships between housing instability and mental health outcomes.

Methods: Using baseline data from the Black Economic Equity Movement (BEEM) guaranteed income trial with …

Clinician Actions In Response To Adverse Childhood Experience (Ace) Screening, J. Scott Ashwood, Nipher Malika, Stephanie Williamson, Charles Engel, Edward Machtinger, Nina Thompson, Amy Shekarchi, Shannon Thyne, Brigid Mccaw, Marguerita Lightfoot, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background and Objective: Adverse Childhood Experiences(ACEs) have a powerful influence on mental health, physical health, and life expectancy. Screening for ACEs and the clinician response to ACEs are critical to addressing the health and well-being of children; however, little is known about the actions clinicians take in response to ACE screening. Therefore, we aimed to examine clinician responses to ACE screening at five California pediatric clinics in a large public health care system. Methods: Patient demographics, indicators of social and behavioral determinants of health (e.g., housing insecurity), the number of ACEs endorsed on a screening instrument, and the actions clinicians …

Systematics Of The Rhinolophus Landeri Complex, With Evidence For 3 Additional Afrotropical Bat Species, Bruce D. Patterson, Terrence C. Demos, Laura Torrent, Amanda L. Grunwald, Cecilia Montauban, Julian C. Kerbis Peterhans, Molly M. Mcdonough, Carl W. Dick, Michael Bartonjo, M. Corrie Schoeman, Multiple Additional Authors

Biology Faculty Publications and Presentations

Roughly a third of all horseshoe bat species (Rhinolophidae: Rhinolophus) are found in Africa, where a recent continent-wide genetic survey suggested the presence of both undescribed and apparently invalid species. Here, we focus on the R. landeri species complex and the recent elevation of R. lobatus Peters, 1852, to species rank. That action created ambiguity in the taxonomy of East African members of the group—are both R. landeri Martin, 1838, and R. lobatus sympatric in East Africa or is another, unnamed species present there? Here, we refine genetic, morphological, and behavioral characterizations of R. landeri and its erstwhile synonyms with …

The Nexus Of Resistance And Neoliberalism In Social Work And Social Welfare: A Scoping Review, Kevin Cherry, Sandra Leotti

School of Social Work Faculty Publications and Presentations

This study intervenes in a growing scholarly dialogue about neoliberalism in social work and social welfare by addressing the undertheorized concept of resistance. We conduct a scoping review of 54 articles published from 2008–2023 to answer two questions: how is resistance discussed in relation to neoliberalism, and what are the practice elements of resistance? Findings highlight resistance as a diverse phenomenon enacted in relation to context-specific manifestations of neoliberalism. A range of actors engage in resistance, including individual practitioners, social service organizations and collective action entities, among others. Resistance occurs across all scales of practice and takes many forms, from …

We also identified a significant gap in human immunodeficiency virus screening and prescription of preexposure prophylaxis.

Climate Hazards And Human Migration: Literature Review, Anna Ivanova, Deepti Singh, Pronoy Rai, Claire Richards, Hugo Vasconcelos, Michael Goldsby

International & Global Studies Faculty Publications and Presentations

Human populations are migrating as a result of climate change. We conducted a systematic literature review examining the relationship between several climate hazards and migration flows. We reviewed 58 empirical studies between 2010 and 2023 that examined current and future migration related to acute and long-term climate hazards. The results indicate that the relationship between climate hazards and migration is diverse and depends on a range of socio-economic factors. Droughts and rising temperatures have a major impact on both international and domestic migration. Our review also reveals that multiple climate hazards collectively tend to intensify domestic migration toward urban areas, …

Institute on Aging Publications

This study explored whether opinions about the government's role in addressing the COVID-19 pandemic vary based on demographic characteristics and racial beliefs. We hypothesized that opinions about the United States (U.S.) government's response to COVID-19 would differ based on an individual's characteristics such as age, race, and racial beliefs.

The Foodpunk City: Advancing Portland's Food Security Through A Shared Ideology Of Adaptation & Resistance, Nickolas Hash

Dissertations and Theses

Food injustice is a form of violence perpetrated by state and corporate actors against a constituency under their governing power, particularly impacting marginalized and impoverished communities. It denies individuals access to nutritious food, perpetuating cycles of poverty, inequality, physical health risks, and social exclusion. Grassroots movements have emerged to challenge dominant paradigms and advocate for food sovereignty, agroecology, and food anarchy. In Portland, the movement represents a nontraditional approach to food security that closely resembles the reactionary ideology of urban "punk" culture. Both groups prioritize community autonomy over food systems, sustainable agricultural practices, and resistance to oppressive structures that perpetuate …

Eviction In Oregon's Subsidized Affordable Housing, Yi Wang, Lisa K. Bates, Azad Amir-Ghassemi, Minji Cho, Marisa Zapata, Jacen Greene, Colleen Carroll, Devin Macarthur

Center for Urban Studies Publications and Reports

Despite Oregon's expanded investments in affordable housing development and eviction prevention, over 5,400 eviction cases were filed in the state’s subsidized housing from January 2019 to December 2023. This report maps out the landscape of subsidized housing eviction in Oregon and brings attention to the high share of eviction judgments in subsidized eviction cases, the disproportionate rate of eviction filings from housing-authority-contracted management companies and nonprofit housing providers, and the great disparities in legal representation between landlords and tenants.

Evaluation Of Transplant Benefits With The Us Scientific Registry Of Transplant Recipients By Semiparametric Regression Of Mean Residual Life, Ge Zhao, Yanyuan Ma, Huazhen Lin, Yi Li

Mathematics and Statistics Faculty Publications and Presentations

Kidney transplantation is the most effective renal replacement therapy for end stage renal disease patients. With the severe shortage of kidney supplies and for the clinical effectiveness of transplantation, patient’s life expectancy posttransplantation is used to prioritize patients for transplantation; however, severe comorbidity conditions and old age are the most dominant factors that negatively impact posttransplantation life expectancy, effectively precluding sick or old patients from receiving transplants. It would be crucial to design objective measures to quantify the transplantation benefit by comparing the mean residual life with and without a transplant, after adjusting for comorbidity and demographic conditions. To address …

A Systematic Unified Approach For Addressing Temporal Instability In Road Safety Analysis, Kazi Redwan Shabab, Tanmoy Bhowmik, Mohamed H. Zaki, Naveen Eluru

Civil and Environmental Engineering Faculty Publications and Presentations

Multivariate models are widely employed for crash frequency analysis in traffic safety literature. In the context of analyzing data for multiple instances (such as years), it becomes essential to evaluate the stability of parameters over time. The current research proposes a novel approach, labelled the mixed spline indicator pooled model, that offers significant enhancement relative to current approaches employed for capturing temporal instability. The proposed approach entails carefully creating independent variables that allow us to measure parameter slope changes over time and can be easily integrated into existing methodological frameworks. The current research effort compares four multivariate model systems: year …

Accelerating Growth Of Human Coastal Populations At The Global And Continent Levels: 2000–2018, A. G. Cosby, V. Lebakula, David Swanson, K. Bergene, D. E. Bloom, Multiple Additional Authors

Publications, Reports and Presentations

Current human population growth along Earth’s coasts is on a collision path with anticipated consequences of increasing natural and anthropogenic induced coastal hazards. Using recently-available ambient, dasymetric data, we developed methods to estimate annual continental and global coastal populations from (2000–2018) measured horizontally from the shoreline inward. We found: (1) large concentrations of population in relatively small bands and regions along the coast (~ 2 billion within 50 km and ~ 1 billion within 10 km); (2) higher growth rates of coastal population than inland population (an addition of 463 million within 50 km and 233 million within 10 km); …
