“We Were Queens.” Listening To Kānaka Maoli Perspectives On Historical And On-Going Losses In Hawai’I, Antonia R.G. Alvarez, Val. Kanuha, Maxine K.L. Anderson, Cathy Kapua, Kris Bifulco

School of Social Work Faculty Publications and Presentations

This study examines a historical trauma theory-informed framework to remember Kānaka Maoli (Native Hawaiian) and lesbian, gay, bisexual, transgender, queer, and/or māhū (LGBTQM) experiences of colonization in Hawai`i. Kānaka Maoli people and LGBTQM Kānaka Maoli face health issues disproportionately when compared with racial and ethnic minorities in Hawai’i, and to the United States as a whole. Applying learnings from historical trauma theorists, health risks are examined as social and community-level responses to colonial oppressions. Through the crossover implementation of the Historical Loss Scale (HLS), this study makes connections between historical losses survived by Kānaka Maoli and mental health. Specifically, this …

Smoking Behaviors In Patients Offered Lung Cancer Screening, Sara Elizabeth Golden

Dissertations and Theses

In the United States, smoking causes preventable diseases, including lung cancer, which is the leading cause of cancer deaths. Improving smoking cessation rates is important to decrease lung cancer deaths. Health care visits with a discussion about lung cancer screening (LCS) may help in increasing prevalence of smoking cessation. Importantly, insurers now require clinicians to have a shared decision-making discussion with patients that includes discussion of smoking abstinence before they can receive an LCS scan (i.e., a low-dose computed tomography scan). This discussion may represent a unique opportunity to encourage smoking cessation since it may prompt positive smoking behavior change. …

Microplastics In Pacific Northwest Bivalves: Ecological Prevalence, Harvester-Consumer Exposure, And Aquarium Exhibit Outcomes, Britta Rahel Baechler

Dissertations and Theses

Up to 23 million metric tons of mismanaged plastics enter the global ocean annually. Microplastics (MPs;<5mm) degrading. MPs leak into the environment and now pervade every corner of the earth, with implications for animal, plant, ecosystem and human health. It is important to understand localized environmental MP prevalence, distribution and organismal uptake in order to determine the extent of MP pollution, and ultimately unlock solution sets to reduce transmission of MPs into the natural world. In Chapter 2, I quantified MP types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor clams (Siliqua patula) from 15 coastal sites in Oregon. Both of these species are integral to culture, economy, gastronomy and food security along the United States West Coast. In Chapter 3, I quantified MPs in Pacific razor clams collected from 8 Olympic Coast, Washington sites, administered questionnaires to recreational razor clammers and subsequently estimated annual MP exposure of those Olympic Coast razor clam harvester-consumers surveyed. In Chapter 4, I designed and installed an educational ocean plastic …

“Rapunzel, Rapunzel, Lanza Tu Pelo”: Storytelling In A Transcultural, Translanguaging Dialogic Exchange, Erin E. Flynn

School of Social Work Faculty Publications and Presentations

In this study, we examined story circles to understand how the small‐group activity supports and shapes the storytelling of young students in multicultural, multilingual preschool classrooms. Through a representative example, we show how language development unfolds in the context of a transcultural and translanguaging dialogic exchange of stories. We describe features of increasing linguistic complexity present in students’ storytelling as they established affinity‐affirming connections over ideas, shared ways of languaging, and shared ways of storytelling. By examining changes in one student’s storytelling in the context of a mixed‐language story circle group, we offer insights into both language development and features …

Paranormal Psychology: Psy410, Larry R. Martinez

PDXOpen: Open Educational Resources

This OER packet contains the course materials for PSY410: Paranormal Psychology. Although often dismissed as a pseudoscience, there are many things we can learn about human beliefs, attitudes, and behaviors by studying phenomena that our current science cannot explain. The course begins with a history of real scientific studies that have been conducted to try and determine whether things like extrasensory perception, telepathy, and telekinesis are real phenomena, with a particular emphasis on what those studies can teach us about the scientific method more generally. This is followed by an examination of things related to the afterlife (e.g., ghosts, mediums, …

Enclosing Water: Privatization, Commodification, And Access, Daniel Jaffee

Sociology Faculty Publications and Presentations

This chapter examines the global political economy of access to drinking water, with particular attention to the implications for environmental and social justice. After reviewing theoretical approaches to the privatization and commodification of drinking water, the chapter examines the institutional and ideological drivers, dynamics, and effects of the enclosure of municipal (tap) water supplies, and the substantial countermovements it has generated, drawing on case studies from both the global South and the North. The chapter briefly reviews the present status of municipal water privatization, and then turns to another major modality of water commodification: bottled water. It explores the dramatic …

Six Feet Of Distance Between Belonging: Expansions And Maintenance Of Citizenship During Covid-19, Johnathon Daniel Vargas

University Honors Theses

Citizenship is the dominant 'political regime of belonging' that is coupled with rights and access to necessary material resources. This paper reviews the dimensions of citizenship, its connection to the nation-state, and analytical approaches to belonging. The review of literature is then applied to an analysis of how COVID-19 has challenged notions of citizenship by revealing maintenance strategies and enactments of belonging in Portland, Oregon and the surrounding region. This paper uses qualitative research to analyze events, communication, activities, and conditions of those who lack citizenship, mediated through local media. Data collected from the first 3 months of the COVID-19 …

Importance Of Interpersonal Relationships In Cbgt, Alexxa Badley

University Honors Theses

A literature review was conducted to answer the question, can CBGT, and its emphasis on interpersonal relationships bolster the treatment of depression in adolescents? Adolescents were defined as anyone between the ages of 13-17, and depression was diagnosed by the DSM-V. It was found that CBGT had strong effectiveness in the treatment of depression, lowering symptoms across the board. Teens found solidarity in having others that could relate to them and their personal experiences. Potential downfalls were the fact that time management was crucial to better treatment, making sure everyone had a chance to speak, as well as strong communication …

A Posteriori Error Estimates For Maxwell's Equations Using Auxiliary Subspace Techniques, Ahmed El Sakori

Dissertations and Theses

The aim of our work is to construct provably efficient and reliable error estimates of discretization error for Nédélec (edge) element discretizations of Maxwell's equations on tetrahedral meshes. Our general approach for estimating the discretization error is to compute an approximate error function by solving an associated problem in an auxiliary space that is chosen so that:

-Efficiency and reliability results for the computed error estimates can be established under reasonable and verifiable assumptions.

-The linear system used to compute the approximate error function has condition number bounded independently of the discretization parameter.

In many applications, it is some functional …

The Impact Of Paternal Caregivers For Youth Who Commit Sexual Offenses, Miranda Hope Sitney

Dissertations and Theses

This dissertation presents three manuscripts exploring the impact of caregivers, particularly male caregivers, on the development of juvenile sexual offending behavior. The first manuscript investigated the role of disrupted caregiving for juvenile sexual offenders compared to non-offending juveniles and youth who committed non-sexual crimes. The results indicated that juvenile sexual offenders have particularly poor relationships with their primary caregivers, especially if their primary caregiver was male. The second manuscript is a systematic literature review that explored the pathways through which male caregivers may influence the sexually aggressive behavior of their sons. A total of thirty-four articles describing three pathways (i.e., …

Inclusion For Speech-Language Pathology Minority Graduate Students, Teresa Michelle Roberts

Dissertations and Theses

Speech-language pathologists provide assessment and intervention for communication, cognition, and swallowing disorders for individuals across the lifespan in educational, medical, and private practice settings. The demographics of professionals in the field do not reflect those of the general public in regard to race and ethnicity, gender, socioeconomic status, LGBTQ+, and disability. Lack of representation of minorities limits research, policy, and services designed to serve diverse populations. Although initiatives have sought to address lack of diversity of speech-language pathologists, limited research on the graduate training experience for minority students is available. Since a master's degree is required to become a speech-language …

Home Resources Supporting Workplace Resources: An Investigation Of Moderated Intervention Effects From The Study For Employment Retention Of Veterans (Serve), Sarah Nielsen Haverly

Dissertations and Theses

Social support directly impacts psychological outcomes both within the home and work domains. Hammer and colleagues suggest that social support at work from supervisors is related to a number of positive workplace outcomes. Kossek et al. elaborated that social support from supervisors is additionally effective when it is tailored to the unique needs of workers (i.e., role demands). The Veteran Supportive Supervisor Training (VSST) educates supervisors how to better support former service-members employed within the civilian workplace. Additional sources of social support are also key to positive outcomes for workers. Research shows that support from a partner or spouse can …

On Making Experimental Design Choices: Discussions On The Use And Challenges Of Demand Effects, Incentives, Deception, Samples, And Vignettes, Stephanie Eckerd, Scott Duhadway, Elliot Bendoly, Craig R. Carter, Lutz Kaufmann

Business Faculty Publications and Presentations

In late 2018, the Journal of Operations Management published an invited methods article by Lonati et al. (2018) to provide guidance to authors on how to design behavioral experiments to achieve the rigor required for consideration in the journal. That article was written as a response to a number of behavioral research submissions to JOM, each dealing with interesting topics but viewed by the editors to possess poor design choices at inception. While the Lonati et al. (2018) piece provides experimental guidance fitting to certain research agendas, questions have arisen concerning whether and how exactly to implement some of the …

At The Intersection Of Safety + Race + Transportation, Charlene Mcgee

PSU Transportation Seminars

Transportation policies at the local, regional, state and national levels have a direct impact on urban land use and development patterns. Transportation intersects with multiple areas including public health, education, climate change, physical activity, health outcomes, build environment, violence, safety, social cohesion and the wellness of communities. For the health outcomes influenced by transportation, disparities exist by race, ethnicity, and socioeconomic status in Multnomah County. Disproportionate exposure to injury, air pollution, and noise contributes to inequitable burdens of injuries and chronic disease among race and ethnic groups. This is exacerbated by lack of access to safe places for active transportation …

Contextualizing Educational Disparities And The Evaluation Of Teacher Quality, Dara Shifrer

Sociology Faculty Publications and Presentations

Value added scores, statistical estimates of teacher quality, are representative of neoliberal logic. The higher average scores of teachers of socially advantaged students raise concerns that scores are inaccurate and unfair, and propagate decontextualized neoliberal understandings of the nature of learning and teachers’ work. This study uses longitudinal data from roughly 4,500 teachers in a large urban district between 2007–08 through 2012–13 to follow individual teachers as they switch into schools of different “performance levels” over time. Fixed-intercept models tracking individual teachers between 2007–08 and 2012–13 showed scores increased for teachers who switched into high-performing schools and decreased for teachers …

Global Diversity and Inclusion Publications and Presentations

This symposium features four scholar-practitioners of color working across the STEM-Medicine (STEM-M) pipeline who are actively engaging their cultural intuition (Delgado Bernal, 1998) to create access to higher education by challenging dominant pathways, practices, and cultures related to college readiness/preparedness, success, persistence, and the workforce transition.

Session Objectives

• Challenge systemic barriers in diverse educational settings, such as deficit-frameworks and their associated normative practices
• Promote asset-based approaches and frameworks to achieve better equity, access, and opportunity for students of color in STEM-M pathways in K-16 settings
• Facilitate discussion with the audience on how they can replicate a similar approach of change …

Bus Stops Improvements Along Utah Corridor Increase Ridership And Ada Accessibility, Keith Bartholomew

TREC Project Briefs

A bus stop can be anything from a simple signpost stuck in the grass, to a comfortable shelter with seating and paved access to the sidewalk. For many U.S. transit agencies across the country, improving facilities at bus stops is a priority. But how much do these improvements actually affect ridership? A lot, it turns out. A new NITC study, co-funded by the Utah Transit Authority (UTA) and led by Keith Bartholomew of the University of Utah, found a 5.9% increase in boardings after improvements were made to a series of bus stops in Salt Lake City - compared to …

Incorporating Local Foods Into Low-Income Families’ Home-Cooking Practices: The Critical Role Of Sustained Economic Subsidies, Jennifer Gaddis, Amy K. Coplen, Molly Clark-Barol, Allea Martin, Claire K. Barrett, Lauren Lubowicki

Urban Studies and Planning Faculty Publications and Presentations

Alternative food practices, including farmers markets and CSAs, are often inaccessible to lowincome families. Subsidized CSAs and fruit and vegetable prescription programs have the potential to decrease food insecurity, increase fresh fruit and vegetable consumption, and generate better health outcomes. However, several challenges can limit logistics of distribution and an inability to cook from scratch due to a lack of kitchen infrastructure, time, or skills. In this paper, we investigate two dietrelated health programs conducted with community partners in Madison, Wisconsin, and Portland, Oregon. We used photovoice to evaluate and enhance these programs, which supplied lowincome participants with free or …

Distributed Energy Resource Aggregation Using Customer-Owned Equipment: A Review Of Literature And Standards, Manasseh Obi, Tylor Slay, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Large-scale deployment of renewable energy resources, both utility-scale and distributed, create reliability concerns for electrical power system operators. The weather-dependent, non-dispatchable nature of renewable resources decreases the ability of operators to match supply with demand. Concurrently, distributed energy resources, defined as small-scale loads, generation sources, and storage systems, are becoming ubiquitous within modern electrical systems. This literature review presents the grid services that utilities use to alleviate power systems reliability concerns, particularly those caused by renewable resources, and how aggregations of residential-scale distributed energy resources can be used to provide these services.

By aggregating distributed energy resources en masse to …

Fire, Native Ecological Knowledge, And The Enduring Anthropogenic Landscapes Of Yosemite Valley, Douglas Deur, Rochelle Bloom

Anthropology Faculty Publications and Presentations

Yosemite Valley is a place with rich and enduring traditions of Indigenous Ecological Knowledge, manifesting in specific management practices that, in turn, leave discernible imprints upon the natural landscape. Historically, the Native American inhabitants of Yosemite Valley have employed a variety of techniques that materially enhance the availability of culturally preferred plant communities. This chapter identifies specific techniques that appear consistently in the oral traditions and written historical accounts of the valley. These methods included anthropogenic burning, pruning and coppicing, clearing underbrush beneath trees, hand eradication (“weeding”) of certain competing species, selective harvesting, smoking, “knocking” of dead wood from the …

Direct Binding Of Tfeα Opens Dna Binding Cleft Of Rna Polymeras, Sung-Hoon Jun, Jaekyung Hyun, Hoyoung Kim, Michael S. Bartlett, Hyun-Soo Cho, Katsuhiko S. Murakami

Biology Faculty Publications and Presentations

Opening of the DNA binding cleft of cellular RNA polymerase (RNAP) is necessary for transcription initiation but the underlying molecular mechanism is not known. Here, we report on the cryo-electron microscopy structures of the RNAP, RNAP-TFEα binary, and RNAPTFEα-promoter DNA ternary complexes from archaea, Thermococcus kodakarensis (Tko). The structures reveal that TFEα bridges the RNAP clamp and stalk domains to open the DNA binding cleft. Positioning of promoter DNA into the cleft closes it while maintaining the TFEα interactions with the RNAP mobile modules. The structures and photo-crosslinking results also suggest that the conserved aromatic residue in the extended winged-helix …

Landscape Genetics Of Plants: Challenges And Opportunities, Mitchell Cruzan, Elizabeth C. Hendrickson

Biology Faculty Publications and Presentations

Dispersal is one of the most important but least understood processes in plant ecology and evolutionary biology. Dispersal of seeds maintains and establishes populations, and pollen and seed dispersal are responsible for gene flow within and among populations. Traditional views of dispersal and gene flow assume models that are governed solely by geographic distance and do not account for variation in dispersal vector behavior in response to heterogenous landscapes. Landscape genetics integrates population genetics with Geographic Information Systems (GIS) to evaluate the effects of landscape features on gene flow patterns (effective dispersal). Surprisingly, relatively few landscape genetic studies have been …

Public Housing With Services For Older Adults With Developmental Disabilities: Differences In Efficacy Among Asian And White Communities, Junghee Lee, William Donlan, Paula C. Carder, Leigh Grover, Insik Hwang, Younghwan Kim, Gretchen Luhr

School of Social Work Faculty Publications and Presentations

This study examined the efficacy of a culturally responsive housing with services model for Asian-American older adults and persons with developmental disabilities separately, and with both for an interaction effect. Study participants, including 278 Whites and 75 Asian Americans, lived in 10 properties of public housing with services in Portland, OR. All Asian-American participants (except four) were immigrants from China, Korea, and Vietnam, and were well connected through community-based health and social services that were delivered onsite and at a nearby center by staff members who were also immigrants from these three countries. Asian-American participants were older, very poor, with …

Extending The Functional Subnetwork Approach To A Generalized Linear Integrate-And-Fire Neuron Model, Nicholas Szczecinski, Roger Quinn, Alexander J. Hunt

Mechanical and Materials Engineering Faculty Publications and Presentations

Engineering neural networks to perform specific tasks often represents a monumental challenge in determining network architecture and parameter values. In this work, we extend our previously-developed method for tuning networks of non-spiking neurons, the “Functional subnetwork approach” (FSA), to the tuning of networks composed of spiking neurons. This extension enables the direct assembly and tuning of networks of spiking neurons and synapses based on the network’s intended function, without the use of global optimization ormachine learning. To extend the FSA, we show that the dynamics of a generalized linear integrate and fire (GLIF) neuronmodel have fundamental similarities to those of …

A Simplified Accuracy Enhancement To The Saleh Am/Am Modeling And Linearization Of Solid-State Rf Power Amplifiers, Haider Al-Kanan, Fu Li

Electrical and Computer Engineering Faculty Publications and Presentations

The Saleh behavioral model exhibits high prediction accuracy for nonlinearity of traveling-wave tube power amplifiers (TWT-PAs). However, the accuracy of the Saleh model degrades when modeling solid-state power amplifiers (SSPAs) technology. In addition, the polynomial expansion of the Saleh model consists of only odd-order terms as analyzed in this work. This paper proposes a novel model accuracy enhancement for the Saleh amplitude-to-amplitude (AM/AM) model when applied to radio frequency (RF) SSPAs. The proposed model enhancement accounts for the second-order intermodulation distortion, which is an important nonlinearity challenge in wideband wireless communications. The proposed static AM/AM model is a three-parameter rational …

The Use Of Wayfinding Apps By Deafblind Travelers In An Urban Environment: Insights From Focus Groups, Amy T. Parker, Martin Swobodzinski, Tara Brown-Ogilvie, Jenna Beresheim-Kools

Special Education Faculty Publications and Presentations

This brief report explores qualitative themes from focus groups with nine individuals who are Deafblind regarding their use of wayfinding apps to support orientation and mobility in an urban environment. Culturally responsive approaches to the design of the focus groups integrated the partnership with Deafblind communication facilitators and ProTactile approaches to solicit naturalistic inquiry on the experiences and preferences of Deafblind travelers. Thematic emergences suggest that participants benefit from various wayfinding apps for orientation and mobility in a densely populated city but they desire greater functionality, consistency of access, equity, and recognition of the unique travel demands faced by Deafblind …

History And Memory In The Intersectionality Of Heritage Sites And Cultural Centers In The Pacific Northwest And Hawai'i, Leah Marie Rosenkranz

Dissertations and Theses

While working to maintain contemporary and future relationships with stakeholders, heritage sites and cultural centers across the United States attempt to tell the history and experiences of the land and people who were once there, are there in the present, and will be there in the future. Fort Vancouver National Historic Site is one of these heritage places. This study is a response to current management needs identified for the Fort Vancouver National Historic Site. Through an internship with the ongoing Fort Vancouver National Historic Site Traditional Use Study, my research examines how heritage sites and cultural centers fulfill the …
