The Impact Of Covid-19 On Transit Workers: Perceptions Of Employer Responses And Associations With Health Factors, Sean P.M. Rice, Leah S. Greenspan, Talya N. Bauer, Jarred Rimby, Todd Bodner, Ryan Olson

Business Faculty Publications and Presentations

COVID-19 has had a substantial impact on transit workers’ lives, especially among public-facing vehicle operators. The current project examined relationships between workers’ knowledge and perceptions of their employer’s COVID-19 safety responses, job attitudes, and health. We surveyed transit workers (N = 174) between July and August 2020 and followed up 3 months later. Fifty-seven workers responded to the follow-up survey. Surveys addressed workers’ knowledge and perceptions of their employer implementing Centers for Disease Control and Prevention (CDC)-recommended COVID-19 safety responses, COVID-19 risk perceptions, job attitudes, and health factors. Employees reported knowledge of their employer implementing ~8 of 12 CDC-recommended responses. …

Integrating Diverse Perspectives For Managing Neighborhood Trees And Urban Ecosystem Services In Portland, Or (Us), Lorena Nascimento, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

Municipalities worldwide are increasingly recognizing the importance of urban green spaces to mitigate climate change’s extreme effects and improve residents’ quality of life. Even with extensive earlier research examining the distribution of tree canopy in cities, we know little about human perceptions of urban forestry and related ecosystem services. This study aims to fill this gap by examining the variations in socioeconomic indicators and public perceptions by asking how neighborhood trees and socioeconomic indicators mediate public perceptions of ecosystem services availability. Using Portland, Oregon (USA) as our case study, we assessed socioeconomic indicators, land cover data, and survey responses about …

Blacks In Oregon, Darrell Millner

Black Studies Faculty Publications and Presentations

Periodically, newspaper or magazine articles appear proclaiming amazement at how white the population of Oregon and the City of Portland is compared to other parts of the country. It is not possible to argue with the figures—in 2017, there were an estimated 91,000 Blacks in Oregon, about 2 percent of the population—but it is a profound mistake to think that these stories and statistics tell the story of the state's racial past. In fact, issues of race and the status and circumstances of Black life in Oregon are central to understanding the history of the state, and perhaps its future …

Beyond “No”: Best Practices For Responding To Resource Requests, Kerry Wu

Library Faculty and Staff Publications and Presentations

At a recent BRASS Virtual Discussion, business librarians commiserated over the shared frustration of having to say “no” regularly to resource requests (RUSA_BRASS, n.d.). As a midcareer business librarian, I still feel the discomfort after having said “no” numerous times. In this article, I will share some of the practices I have found helpful in responding to requests from business faculty for new databases or journals, especially when I have to say “no” without burning bridges.

An Example Of Converting Clinical Study Mortality Data Into A Life Table: The U.S. Population With Sickle Cell Disease, David A. Swanson

Publications, Reports and Presentations

There are approximately 100,000 people in the United States with Sickle Cell Disease (SCD) and the paucity of life tables for this population makes it difficult to determine if research and treatment innovations have improved their life expectancy over time and relative to the general U.S. population. Using mortality data generated in a population-based surveillance study over the period, 2004 to 2008, this paper generates a life table for this study population circa 2006 and applies it to the US population that has SCD. I find that a newborn with this condition circa 2006 had a life expectancy of approximately …

Reconstructability Analysis Of The Predictors Of Physical Functioning Status In Older Americans By Race And Ethnicity, Amanuel Melekin, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper demonstrates the use of reconstructability analysis to examine race/ethnic differences in physical functioning status among older Americans. Reconstructability analysis is an information theory and graph theory method which has been successfully used in multivariate data modeling. The health and retirement study data from 2004 are used for this demonstration. Out of eighteen independent variables included, seven variables appeared in the best models selected. Uncertainty reductions in physical functioning status were substantial across the models but the magnitudes and predictive variables varied slightly by race/ethnicity. Examination of the model probability distributions indicated that composite independent variable states of overlapping …

The Influence Of Colorism On The Hair Experiences Of African American Female Adolescents, Lakindra Mitchell Dove

School of Social Work Faculty Publications and Presentations

This article addresses the prevalence of colorism among the hair care narratives of African American female adolescents. Eleven interviews were conducted to explore the connection between hair and sense of self and self-esteem. During data collection and analysis, the theme surrounding colorism emerged, as many participants discussed its influence on hair, recalling traumatic hair and colorist experiences. This article focuses on the analysis of these narratives using the colorist-historical trauma framework. Three themes emerged: (1) colorist experiences; (2) perceptions of good hair; and (3) the influence of White beauty standards. These themes reflect how participants conceptualized the implications of colorism …

Factors Associated With Poverty Among Refugees In The United States, Mitra Naseh, Miriam Potocky, Shanna L. Burke, Paul H. Stuart, Fatma Huffman

School of Social Work Faculty Publications and Presentations

Background and Purpose: Approximately three million refugees have arrived in the United States in the past four decades. Literature suggests, after arrival in the country and in the short-term period thereafter, it is likely for refugees as New Americans to experience poverty and deprivation in different aspects of life. In this context, knowledge of factors associated with poverty among refugees is important and relevant for social workers as front-line service providers for refugees and economically disadvantaged individuals. Using social exclusion theory as a framework, this study hypothesized that the factors associated with integration in the refugee integration conceptual framework (Ager …

Ready? Set? Go?: Examining Organizational Readiness For Change In A Quality Improvement Intervention For Youth Mentoring Programs, Renee Spencer, Alison L. Drew, Carla Herrera, Bowen Mcbeath, Thomas E. Keller

School of Social Work Faculty Publications and Presentations

The number of youth mentoring programs has risen significantly in recent decades. This trend, coupled with evidence that programs employing a greater number of empirically supported practices achieve more positive effects for youth participants, has prompted increasing interest in how to promote more widespread use of evidence-based practice standards in mentoring programs. In an effort to describe and better understand efforts to implement recommended standards, we studied a multi-level initiative sponsored by a national advocacy organization in which its state-level Affiliates guided local mentoring programs through a structured quality improvement process. Specifically, we examined organizational readiness for change among mentoring …

Distress And Resilience In Resettled Refugees Of War: Implications For Screening, Michael Hollifield, Eric C. Toolson, Sasha Verbillis-Kolp, Beth Farmer, Junko Yamazaki, Tsegaba Woldehaimanot, Annette Holland

School of Social Work Faculty Publications and Presentations

There is little work published about predictors of specific trajectory types of distress in refugees of war during early resettlement in a host country. Data about distress (Refugee Health Screener—15 (RHS-15)) and possible predictors of distress were collected at the domestic medical examination (T1) within 90 days of arrival and the civil surgeon examination (T2) 11–16 months after T1 for refugee groups from three countries (COU). Descriptive, correlative, analyses of variance, and regression techniques were used to determine trajectory type and their predictors. A higher percentage (7.3%) were distressed at T2 than at T1. By group, the Bhutanese became more …

Pandemic And Protest In 2020: Questions And Considerations For Social Work Research, Kimberly D. Hudson, Gita Mehrotra

School of Social Work Faculty Publications and Presentations

The convergence of the COVID-19 pandemic and social/political protest concerning structural anti-Black racism marks a moment for deep reflection and revision of many taken-for-granted assumptions about our research and academic lives as social work scholars. In this reflexive essay we, as two non-Black qualitative social work scholars, explore some of the questions and considerations for social work research that have surfaced since the emergence of these complex social, political, and economic crises. We organize our reflection around what we study, why, and how we go about studying it. We then offer a discussion of various constraints and challenges that emerge …

“We’Re More Than A Daycare”: Reported Roles And Settings For Early Childhood Professionals And Implications For Professionalizing The Field, Rachel E. Schachter, Qingyu Jiang, Shayne B. Piasta, Erin E. Flynn

School of Social Work Faculty Publications and Presentations

In the US, recent efforts have focused on professionalizing the field of early childhood. One way to indicate professionalism is through the terms used to describe both the field and the workers. However, few have examined how practitioners or researchers describe early childhood professionals’ work. Using multiple data sources and analytic strategies, we examined the ways that those working with young children described their role and setting, as well as how these were described in research and practitioner journals. “Teacher” was the preferred term for both journals and professionals, and terms for setting reflected traditional K-12 school structures. Professionals linked …

Evaluating The N/Ne Preference Policy, Amie Thurber, Lisa K. Bates, Susan Halverson

School of Social Work Faculty Publications and Presentations

North/Northeast Portland has long been the heart of Portland's Black community. By 2010, the area had lost two-thirds of its Black residents to displacement. In response, the City adopted a Preference Policy that prioritizes displaced affordable rental and homeownership applicants. This report describes findings from the first phase of a study to understand what difference this policy is making in the lives of residents.

Interrupting White Supremacy In Field Education: Experiences Of Microaggressions In Placement Settings, Anita Reinette Gooding, Gita Mehrotra

School of Social Work Faculty Publications and Presentations

As social work’s signature pedagogy, field education socializes students into their professional roles as practitioners. However, for students and field instructors of color, racial microaggressions add another dimension to the practice experience. Utilizing findings from a qualitative study exploring the experiences of Black, Indigenous, and People of Color (BIPOC) social work students and agency-based field instructors, this paper highlights experiences of microaggressions in field placement settings. Specifically, BIPOC students and field instructors described being tokenized in agencies, feeling invisible in placement settings, experiencing microaggressions from service users or students, and witnessing microaggressions. Experiences of microaggressions had emotional impacts, and affected …

Dual Panics: A Media Analysis Of Narratives On The Role Of Unauthorized Migration In America's Overdose Crisis, Morgan Godvin

University Honors Theses

Background: The realms of drug policy and immigration policy have long been fueled by misinformation, where sensationalism and panics help shore up political support. Most recently, the "border crisis" has been invoked to explain the "overdose crisis" in mass media narratives. Although the increase in migration is being blamed for illicit drug flows, drug importation occurs primarily through legal points-of-entry. The extent and excess visibility of false narratives linking overdose to migration in mainstream media is unknown.

Methods: We used the Media Cloud ecosystem to compile and characterize mainstream media content published between June 2021 and July 2021 regarding the …

Sensitivity Analysis Of An Agent-Based Simulation Model Using Reconstructability Analysis, Andey M. Nunes, Martin Zwick, Wayne Wakeland

Complex Systems Faculty Publications and Presentations

Reconstructability analysis, a methodology based on information theory and graph theory, was used to perform a sensitivity analysis of an agent-based model. The NetLogo BehaviorSpace tool was employed to do a full 2^k factorial parameter sweep on Uri Wilensky’s Wealth Distribution NetLogo model, to which a Gini-coefficient convergence condition was added. The analysis identified the most influential predictors (parameters and their interactions) of the Gini coefficient wealth inequality outcome. Implications of this type of analysis for building and testing agent-based simulation models are discussed.

Assessing Airborne Radar To Map Glacier Elevations In Alpine Terrain Including Estimated Glacier Volume Change, Bryce Allen Glenn

Dissertations and Theses

Alpine glaciers and perennial snowfields (G&PS) are important hydrologically and ecologically, providing meltwater during the hottest and driest summer periods. Climate warming shrinks these natural reservoirs while temporarily providing increased streamflow. To assess regional changes in glacier volume, from which contribution to streamflow can be estimated, I used NASA's Airborne Glacier and Ice Surface Topography Interferometer (GLISTIN). This instrument mapped the surface topography of alpine glaciers; differencing these elevations from historic elevations derived from topographic maps, volume change is calculated. GLISTIN was flown over the glacier-populated mountain ranges of the western U.S. Of the 3289 glaciers and perennial snowfields with …

Examining Bicycle And Motorized Vehicle Speeds And Their Relationships In The Context Of Urban Roadways, Jaclyn Sue Schaefer

Dissertations and Theses

This thesis presents a compilation of papers exploring passenger car and bicycle speeds through their interactions with each other and with urban roadway factors.

First, following a concern raised in part of the traffic literature that a large mode shift toward bicycling may cause travel time delays and potentially exacerbate congestion instead of alleviate it unless bicycle lanes are installed, an empirical study detailing how the presence of bicycles on urban roads without bicycle lanes may affect passenger car speeds is presented. Pneumatic tube data from six predominantly low speed, low volume roads in Portland, Oregon were utilized to identify …

A Historical Ecology Of Aridland Springs In Desert National Wildlife Refuge, Nuwu/Nuwuvi (Southern Paiute/Chemehuevi) Ancestral Territory, Nevada, Yarrow Sarah Valentine Geggus

Dissertations and Theses

Aridland springs are among the most threatened ecosystems in the world. Vital to desert ecologies and Indigenous cultures, these complex and individualistic ecosystems have layered histories. To inform management in the changing landscape of Desert National Wildlife Refuge, a 1.6 million acre protected area in Southern Nevada, I conducted a historical ecology study of a sample of ten upland springs. Through a six-part interdisciplinary methodology including interviews, archaeological survey, botanical survey, and archival research, I summarize findings into three broad eras: the Nuwu/Nuwuvi pre-Contact Era, the Settler Era, and the U.S. Fish and Wildlife Service Era.

For millennia, Nuwu/Nuwuvi drank …

Environmental And Spatial Factors Affecting Surface Water Quality In A Himalayan Watershed, Central Nepal, Janardan Mainali, Heejun Chang

Geography Faculty Publications and Presentations

Various spatial interrelationships among sampling stations are not well explored in the spatial modeling of water quality literature. This research explores the relationship between water quality and various social, demographic, and topographic factors in an urbanizing watershed of Nepal with a comparison of different connectivity matrices to conceptualize spatial interrelationships. We collected electrical conductivity and dissolved oxygen data from surface water bodies using a handheld probe and used the data to establish relationships with land use, topography, and population density-based explanatory variables at both watershed and 100-m buffer scales. The linear regression model was compared with different eigenvector-based spatial filtering …

The Long-Haul: Buddhist Educational Strategies To Strengthen Students’ Resilience For Lifelong Personal Transformation And Positive Community Change, Namdrol Miranda Adams, Kevin Kecskes

Public Administration Faculty Publications and Presentations

For decades, community engagement scholars have built a robust body of knowledge that explores multiple facets of the higher education community engagement domain. More recently, scholars and practitioners from mainly Christian affiliated faith-based institutions have begun to investigate the complex inner world of community-engaged students’ meaning-making and spiritual development. While most of this fascinating cross-domain effort has been primarily based on “Western” influenced Judeo-Christian traditions, this study explores service-learning/community engagement themes, approaches, rationale, and strategies from an “Eastern” perspective based on the rich tradition of Tibetan Buddhism. This case study research focuses on curricular approaches, influences, and impacts of Buddhist …

The Electronic Hardware Music Subculture In Portland, Oregon, James Andrew Hickey

Dissertations and Theses

Music is relatively understudied as a geographic phenomenon, but recently there has been a shift in academic literature to understand the social, cultural and economic factors that determine music and its development in specific places. The purpose of this study is to examine the Electronic Hardware Music Subculture (EHMS) in Portland, why it thrives, and how it is linked to the local cultural economy. To do this, I used semi-structured, long form interviews with key members of the EHMS. These interviews, and my own observations, gave insight into what factors affect the success of members of the EHMS, and how …

Working Paper No. 45, An Intellectual History Of Josiah Warren, Jaye Balentine

Working Papers in Economics

This inquiry seeks to establish that Josiah Warren (1798-1874) developed a synthesis of anti-capitalist economics and radical individualism which became a unique, yet highly practical strand of anarchism in the United States. This inquiry relies heavily upon Crispin Sartwell’s The Practical Anarchist: Writings of Josiah Warren (2011) for insight into Warren’s contributions. Warren registers as distinct because of his relative isolation from other anarchist thinkers, existing largely as a lone practitioner operating in the western territories of the United States during middle-part of the 19th century. This inquiry considers Warren’s philosophical views as well as his practical program—namely his doctrines …
