Investigating Values In Discourse: Ideals And Social Plans, Luke Edward Hanst

Dissertations and Theses

Social scientists argue that values enable group coordination. I explore two theories of values before turning to evidence provided by Amanda Gorman's inaugural poem, "The Hill We Climb." First, the paradigm of Shalom Schwartz describes values as transsituational goals which enable groups to coordinate action and evaluate the world. I argue the Schwartz paradigm zooms out from values into categories while I need a means to zoom in to understand values in discourse. I turn to the Pragmatic Prospection paradigm to elaborate the cognitive ontology of goals and to understand the function of language. I argue that values are shared …

Can Preference Policies Advance Racial Justice?, Amie Thurber, Lisa K. Bates, Susan Halverson

School of Social Work Faculty Publications and Presentations

Mitigating the harms of gentrification to communities of color is a pressing challenge. One promising approach is preference policies that enable long-term residents to remain in or return to gentrifying neighborhoods. This mixed-methods study evaluates the City of Portland’s “Preference Policy,” which provides targeted affordable rental housing to residents displaced from a historically Black neighborhood. This paper draws on survey, interview, and focus group data to explore resident motivations, changes to well-being, and recommendations for improving the policy. Findings suggest preference policies can enhance well-being, and underscore the need for comprehensive strategies to advance racial justice in gentrifying neighborhoods.

Early Implementation Of A Standards-Based Mathematics Curriculum: Understanding Teacher Perspectives And Concerns, Karen Ann Prigodich

Dissertations and Theses

Standards-based mathematics curricula are intended to shape teachers' classroom instruction in alignment with the content and practices of the Common Core State Standards for Mathematics. Instructional leaders facilitating teachers' implementation of these curricula frequently offer a variety of resources and structures to support effective curriculum use, but teachers themselves do not always find these supports to be helpful. Because teachers' concerns vary, understanding teachers' own perspectives is an important starting place for aligning support with teachers' needs. This case study explored the concerns of teachers from three U.S. school districts during their first year of implementing Bridges in Mathematics, …

Developing Strategies To Enhance Mobility And Accessibility For Community-Dwelling Older Adults, Kate Hyun, Kathy Lee, Caroline Krejci, Nilufer Oran Gibson, Troyee Saha

TREC Final Reports

Mobility disparities among older adults affect their ability to travel and access services. This project seeks to understand challenges, barriers, and gaps that older adults experience, and develop forms of assistance or educational strategies to fill the varying mobility gaps and meet mobility needs. This study characterizes older adults’ use of existing and potential transportation options, including conventional transit, paratransit, and ride-hailing systems, based on surveys collected from 146 low-income older adults in Dallas, TX. Using the survey data and interview data, we develop two mathematical modeling (a Latent Class Cluster Analysis and agent-based modeling (ABM)) and conduct content analysis …

Silica Sinter And The Evolution Of Hot Springs In The Alvord/Pueblo Valleys, Southeast Oregon, Usa, Leslie Allen Mowbray, Michael L. Cummings

Geology Faculty Publications and Presentations

Hot springs in the Alvord/Pueblo valleys in southeastern Oregon are analogous to Basinand- Range hydrothermal systems where heat source and permeable pathways are met through crustal thinning. Silica sinter deposition at Mickey Springs, Alvord Valley, predates the late Pleistocene high stand of pluvial Lake Alvord. At Borax Lake, Pueblo Valley, sinter deposition occurred during the Holocene. This study examines the evolution of springs at Mickey Springs, where three morphologies of sinter are present: (1) basalt clasts surrounded by sinter in interbedded conglomerate and sandstone, (2) pool-edge and aprons of sinter surrounding depressions (12–32 m diameter), and (3) quaquaversal sinter mounds …

Institutional Theory In Sport: A Scoping Review, Jonathan Robertson, Mathew Dowling, Marvin Washington, Becca Leopkey, Dana Lee Ellis, Lee Smith

Business Faculty Publications and Presentations

Institutional theory has generated considerable insight into fundamental issues within sport. This study seeks to advance Washington and Patterson’s review by providing an empirical review of institutional theory in sport. We follow Arksey and O’Malley’s scoping review protocol to identify 188 sport-related institutional studies between 1979 and 2019. Our review provides evidence regarding the state of institutional scholarship within sport via an analysis of authorship, year, journal, methodology, method, study population, and use of institutional constructs (legitimacy, isomorphism, change, logics, fields, and work). Rather than a hostile takeover or a joint venture proposed in Washington and Patterson’s review, the relationship …

The 2019 Conference On Health And Active Transportation: Research Needs And Opportunities, David Berrigan, Astrid Dannenberg, Michelle Lee, Kelly Rodgers, Janet R. Wojcik, Behram Wali, Calvin P. Tribby, Ralph Buehler, James F. Sallis, Multiple Additional Authors

Urban Studies and Planning Faculty Publications and Presentations

Active transportation (AT) is widely viewed as an important target for increasing participation in aerobic physical activity and improving health, while simultaneously addressing pollution and climate change through reductions in motor vehicular emissions. In recent years, progress in increasing AT has stalled in some countries and, furthermore, the coronavirus (COVID-19) pandemic has created new AT opportunities while also exposing the barriers and health inequities related to AT for some populations. This paper describes the results of the December 2019 Conference on Health and Active Transportation (CHAT) which brought together leaders from the transportation and health disciplines. Attendees charted a course …

An Adjustable Stiffness Torsional Magnetic Spring With A Linear Stroke Length, Dawei Che, Jonathan Z. Bird, Alex Hagmüller, Md Emrad Hossain

Electrical and Computer Engineering Faculty Publications and Presentations

This paper presents the analysis, mechanical design, and proof-of-principle experimental testing of a new type of adjustable stiffness torsional magnetic spring for an ocean generator application. Unlike prior published designs the rotary magnetic spring is shown to have a highly linear adjustable stroke length. The presented torsional spring is experimentally shown to be able to create a ± 45° angular stroke range with a peak torque of ± 39.1 N·m. The stiffness is adjusted by using a stepper motor to axially adjust the axial magnet offset. The stepper motor contains a brake so that power is not expended when maintaining …

Concolic Execution Of Nmap Scripts For Honeyfarm Generation, Zhe Li, Bo Chen, Wu-Chang Feng, Fei Xie

Computer Science Faculty Publications and Presentations

Attackers rely upon a vast array of tools for automating attacksagainst vulnerable servers and services. It is often the case thatwhen vulnerabilities are disclosed, scripts for detecting and exploit-ing them in tools such asNmapandMetasploitare released soonafter, leading to the immediate identification and compromise ofvulnerable systems. Honeypots, honeynets, tarpits, and other decep-tive techniques can be used to slow attackers down, however, such approaches have difficulty keeping up with the sheer number of vulnerabilities being discovered and attacking scripts that are being released. To address this issue, this paper describes an approach for applying concolic execution on attacking scripts in Nmap in …

Ways Forward In Preventing Severe Maternal Morbidity And Maternal Health Inequities: Conceptual Frameworks, Definitions, And Data, From A Population Health Perspective, Suzan L. Carmichael, Barbara Abrams, Alison El Ayadi, Can Liu, Henry C. Lee, Deirdre J. Lyell, Audrey Lyndon, Elliott K. Main, Mahasin Mujahid, Lu Tian, Jonathan Snowden

OHSU-PSU School of Public Health Faculty Publications and Presentations

The objective of this commentary was to call attention to challenges to identifying population-level strategies for preventing SMM and its inequities, and to propose solutions. We focus on challenges to conducting research related to SMM within the U.S. context, although the points raised have broader global applicability. The challenges discussed include 1) the conceptual frameworks used to understand SMM, 2) defining SMM, and 3) the availability of data to assess SMM. By addressing these issues, we aim to advance research and efforts to improve health across the life course for people who give birth.

Development Of Intelligent Multimodal Traffic Monitoring Using Radar Sensor At Intersections, Siyang Cao, Yao-Jan Wu, Feng Jin

TREC Final Reports

Multimodal traffic monitoring is critical for improving mobility and safety at intersections with potential conflicts among various modes of transportation. Traditional traffic monitoring approaches utilizing cameras cannot work reliably during the night and under hazardous weather conditions. We propose to build a new intelligent multimodal traffic monitoring device using the low-cost mmWave radar. The proposed device can reliably distinguish different modes (such as buses, pedestrians, bicyclists, trucks, motorcycles, etc.), and determine the counts, speed, and moving directions of every single target in an urban environment under various lighting and weather conditions. In the study, a low-cost prototype system will also …

New Mobility For All: Bringing Emerging Transportation Options To Underserved Communities, John Macarthur, Nathan Mcneil

TREC Project Briefs

Low-income residents, immigrants, seniors, and people with disabilities – these are people who stand to gain the most from new tools and services that reduce transportation costs and travel time. However, issues of affordability, technology adoption, banking access or other barriers can limit access to these new mobility opportunities. In the latest project funded by the National Institute for Transportation and Communities (NITC), New Mobility For All, Portland State University researchers Nathan McNeil, John MacArthur and Huijun Tan worked with the City of Portland’s Bureau of Transportation (PBOT) to evaluate a local pilot program: the Transportation Wallet for Residents of …

Improving Mobility And Quality Of Life For Older Adults, Kate Hyun, Caroline Krejci, Kathy Lee

TREC Project Briefs

As we get older, transportation provides a vital link between home and community. Without reliable and easy ways to get around, many older adults (especially those who live alone) have limited access to essentials like groceries and medicine, let alone social interaction. A new report from the University of Texas at Arlington (UTA), Developing Strategies To Enhance Mobility And Accessibility For Community-Dwelling Older Adults, looked at the mobility challenges, barriers, and gaps that older adults experience, with an eye toward developing forms of assistance or educational strategies to fill those gaps.

New Radar Sensor Technology For Intelligent Multimodal Traffic Monitoring At Intersections, Siyang Cao, Yao-Jan Wu, Feng Jin

TREC Project Briefs

Intelligent Transportation Systems (ITS) need traffic data to run smoothly. At intersections, where there is the greatest potential for conflicts between road users, being able to reliably and intelligently monitor the different modes of traffic is crucial.

The Federal Highway Administration estimates that more than 50 percent of the combined total of fatal and injury crashes occur at or near intersections. For pedestrians the intersection is a particularly dangerous place: the City of Portland, OR identified that two-thirds of all crashes involving a pedestrian happen at intersections. And when darkness comes earlier in fall and winter, crashes increase dramatically. So …

The Association Of Paid Medical And Caregiving Leave With The Economic Security And Wellbeing Of Service Sector Workers., Julia M. Goodman, Daniel Schneider

OHSU-PSU School of Public Health Faculty Publications and Presentations

Service-sector workers in the U.S. face extremely limited access to paid family and medical leave, but little research has examined the consequences for worker wellbeing. Our objective was to determine whether paid leave was associated with improved economic security and wellbeing for workers who needed leave for their own serious health condition or to care for a seriously ill loved one.

Estimated Amounts And Rates Of Carbon Mobilized By Landsliding In Old-Growth Temperate Forests Of Se Alaska, Bryce A. Vascik, Adam M. Booth, Brian Buma, Matteo Berti

Geology Faculty Publications and Presentations

Landslides, a forest disturbance, mobilize carbon (C) sequestered in vegetation and soils. Mobilized C is deposited either onto hillslopes or into the water, sequestering C from and releasing C to the atmosphere at different time scales. The C-dense old-growth temperate forests of SE Alaska are a unique location to quantify C mobilization rate by frequent landslides that often evolve into saturated moving masses known as debris flows. In this study, the amount of C mobilized by debris flows over historic time scales was estimated by combining a landslide inventory with maps of modeled biomass and soil carbon. We analyzed SE …

Data From: “Developing Strategies To Enhance Mobility And Accessibility For Community-Dwelling Older Adults”, Kate Hyun, Kathy Lee, Caroline Krejci

TREC Datasets and Databases

This study administered a survey to 146 lower-income adults in Dallas, TX, aged 55 and older, between February and June 2020. As affordable public transportation options target senior citizens age 65 and older, this study focused on older adults as aged 65 and over. However, we also recruited adults aged 55 to 64 to distinguish how emerging seniors differently perceive or perform transportation activities compared to current older adults. In a partnership with a local organization providing resources and information for older adults and family caregivers located in Dallas, we used snowball sampling by recruiting participants from Foster Grandparent Program …

School of Social Work Faculty Publications and Presentations

Objective: This article describes the use of community-based participatory research (CBPR) to foster bidirectional and equitable academic-community partnerships in two studies related to interpersonal violence and disability. Method: We analyzed our methods and experiences in conducting these studies to focus on the ways in which CBPR methodology was used to jointly promote and enhance research and advocacy surrounding violence and disability in the research processes themselves and the resulting assessment and intervention products. Results: Our use of CBPR methodology allowed us to identify and address critical issues related to violence in the disability community, such as disability-related forms and experiences …

Lifelong Instability And Perceived Risk Of Future Homelessness In Older Adults, Sarah Dys, Anna Steeves-Reece, Paula Carder

Institute on Aging Publications

Housing has long been considered a social determinant of individual and population health. Older adults with low incomes face several challenges to maintaining stable, affordable housing. Using data from a previous explanatory study of older adults waitlisted for housing assistance (n = 267), we explore individual characteristics and themes associated with older adults’ perceived housing instability and risk of future homelessness. This mixed-methods study identifies salient themes of financial insecurity, age discrimination, employment and health, interpersonal relationships, and trauma. Our analysis and findings highlight experiences of instability over the life course related to older adults’ current housing circumstances.

Contributions Made By Undergraduates To Research Projects: Using The Credit Taxonomy To Assess Undergraduate Research Experiences., Matt Honoré, Thomas E. Keller, Jen Lindwall, Rachel Crist, Leslie Bienen, Adrienne Zell

School of Social Work Faculty Publications and Presentations

The authors developed a novel tool, the CREDIT URE, to define and measure roles performed by undergraduate students working in research placements. Derived from an open-source taxonomy for determining authorship credit, the CREDIT URE defines 14 possible roles, allowing students and their research mentors to rate the degree to which students participate in each role. The tool was administered longitudinally across three cohorts of undergraduate student-mentor pairs involved in a biomedical research training program for students from diverse backgrounds. Students engaged most frequently in roles involving data curation, investigation, and writing. Less frequently, students engaged in roles related to software …

Making A Water Data System Responsive To Information Needs Of Decision Makers, Alida Cantor, Michael Kiparsky, Susan S. Hubbard, Ronan Kennedy, Lidia Cano Pecharroman, Kamyar Guivetchi, Gary Darling, Christina Mccready, Roger Bales

Geography Faculty Publications and Presentations

Evidence-based environmental management requires data that are sufficient, accessible, useful and used. A mismatch between data, data systems, and data needs for decision making can result in inefficient and inequitable capital investments, resource allocations, environmental protection, hazard mitigation, and quality of life. In this paper, we examine the relationship between data and decision making in environmental management, with a focus on water management. We focus on the concept of decision-driven data systems—data systems that incorporate an assessment of decision-makers' data needs into their design. The aim of the research was to examine the process of translating data into effective …

Pedestrian Safety And Social Equity In Oregon, Josh Roll, Nathan Mcneil

PSU Transportation Seminars

Past research and planning has highlighted the existence of pedestrian injury disparities throughout the US and some local agencies have performed cursory analysis in Oregon. However, no statewide analysis of pedestrian injuries in Oregon has been completed to see how these injury outcomes differ by race and income.

This presentation aims to help better understand the factors that result in disparate pedestrian injury outcomes for different sociodemographic groups. This research uses data from a variety of sources to understand pedestrian injuries by social equity measures including income, poverty, race, ethnicity, disability and English proficiency. The authors conclude that Black, Indigenous …

Efficacy Of Curcumin Supplementation In Asthma: A Systematic Review And Meta-Analysis, Tabitha M. Grow, Adam Sadowski

PSU McNair Scholars Online Journal

Objective: Over 23 million people are affected by asthma in the United States and 262 million individuals globally. Asthma, if poorly controlled, is associated with significant morbidity as well as increased risk for mortality. Several complex inflammatory pathways and processes are involved leading to an increase in immune cell activation. Curcumin, the active constituent found in turmeric, has been studied in numerous in-vivo and in-vitro studies to generate anti-inflammatory effects in pulmonary diseases. More recently, an increase in clinical data has become available, and since the most recent review assessing the role of curcumin in pulmonary disorders, additional clinical …

"We Had To Rely On Each Other": Voices Of Latinx Foster Youth With Experiences In Care With Siblings, Isabella B. Ginsberg

PSU McNair Scholars Online Journal

Relationships between members of sibling groups have been found to impact well-being for children who enter foster care (Herrick & Piccus, 2005). Being placed in stranger foster care is often challenging and can be traumatic with children reporting confusion, worry, and loss of identity and sense of belonging (Herrick & Piccus, 2005, Unrau et al, 2008). While there is some research that explores the experiences of siblings groups in foster care and others separately that examines Latinx children in foster care, there is very little information that looks into the potentially unique experiences of Latinx individuals who were in care …

Japanese-English Code-Switching By Postwar Speakers In Contemporary America, Andre John Shepherd

Dissertations and Theses

In her examination of Japanese-English bilingualism in Toronto, Nishimura (1995b) demonstrated that second-generation Japanese-Canadians varied their speech dependent on the audience they were addressing. According to her, the Japanese-Canadians spoke primarily in English to fellow second-generation speakers, while maintaining conversations in Japanese with those who had spent their formative years in Japan. However, when addressing audiences composed of both groups, they switched back and forth evenly between the two languages.

Following research done by Woolard (1989) on the effects of societal influences on language, the state of the Japanese-Canadians can be related to the breakup of the ethnic enclaves in …

Centering Equity In Sustainable Food Systems Education, Eleanor J. Sterling, Erin Betley, Selena Ahmed, Sharon Akabas, Daniel J. Clegg, Shauna Downs, Betty T. Izumi, Pamela Koch, Sara M. Kross, Karen Spiller, Lemir Teron, Will Valley

OHSU-PSU School of Public Health Faculty Publications and Presentations

Sustainable food systems education (SFSE) is rapidly advancing to meet the need for developing future professionals who are capable of effective decision-making regarding agriculture, food, nutrition, consumption, and waste in a complex world. Equity, particularly racial equity and its intersectional links with other inequities, should play a central role in efforts to advance SFSE given the harmful social and environmental externalities of food systems and ongoing oppression and systemic inequities such as lack of food access faced by racialized and/or marginalized populations. However, few institutional and intra-disciplinary resources exist on how to engage students in discussion about equity and related …

The Longitudinal Effects Of A Family And Sleep Supportive Intervention On Service Member Anger And Resilience, Shalene Joyce Allen

Dissertations and Theses

The vast majority of workplace intervention research on employee anger and resilience primarily focuses on individual-level strategies for mitigating employee anger and resilience outcomes in the workplace, with no studies having examined these outcomes with tangible occupational health interventions utilizing organizational-level techniques. Thus, the current study extends the literature on how to provide improvements in employee anger and resilience using higher system and organizational change mechanisms by providing evidence-based support for the effectiveness of a Total Worker Health® intervention, referred to as the Family and Sleep Supportive Intervention Training (FaSST). This approach employs both health protection and health promotion strategies …
