Small And Rural Libraries Have Persevered Amid Challenges, Kathi Inman Berens

English Faculty Publications and Presentations

When the Public Library Association holds its 2022 conference in Portland March 23-25, those overseeing the event will include Stephanie Chase, an association board member and the executive director of the Libraries of Eastern Oregon.

About one-third of libraries in eastern Oregon are staffed with just one person. Still, Chase’s organization, a consortium of 15 rural county libraries, offers access to a bigger collection of materials than people living in the sparsely populated region could previously have dreamed of, including the 66,000 ebooks and audiobooks accessible on a smartphone through OverDrive’s Libby app.

Serving Students With Disabilities Who Are Culturally And Linguistically Diverse In Rural Communities: Technology Access Is Essential, Benjamin Gallegos, Lisa A. Dieker, Rebecca Smith, Nicole C. Ralston

Northwest Journal of Teacher Education

Before the COVID-19 pandemic changed the educational landscape, students with disabilities, especially those who are culturally and linguistically diverse, and their special education teachers who worked and attended schools located in rural communities faced barriers most schools and communities experienced nationwide. As schools shifted to remote virtual learning due to the COVID-19 pandemic, rural schools were already at a disadvantage with the lack of resources with technology access. The call for addressing shortcomings in the various digital technology supports towards enhancing the teachers’ delivery of content and the students’ academic outcomes has been a continual challenge to address. This paper …

Le Gout Qui Reste: Cultural Identity And Belonging In Ook Chung's Kimchi, Taurean James Weber-Laurencio

Dissertations and Theses

The emphasis placed on the questioning of identity in Québécois society since the Quiet Revolution of the mid-twentieth century continues to this day. Whereas this search for a specifically Québécois identity was originally cast in terms of an Anglophone/Francophone divide, the influx of migrants from around the world to the province since the 1970s has rendered such a simplistic, binary discourse impossible. The population of Québéc in general and of Montréal in particular is now multicultural; visible minorities now constitute twenty-six percent of the Montréal populace. While most migrants in Québéc are able to find a niche in Montréal in …

Coming To Know The Local Environment: Children's Experiences In Rautamai Gaunpalika, Nepal, Elsie Nicole Love

Dissertations and Theses

This qualitative research, conducted over three months from late monsoon season into early fall of 2018 with twenty-six children and thirteen adults, explores how children in the hills of Rautamai Gaunpalika, Province 1, Nepal come to know their local environment. Semi-structured interviews with children, their family members, and teachers, and participant observation with children as they worked and played in forests, fields, and streams, suggest that outside of school, children come to know their local environment in the following ways: through participation in and application of knowledge to subsistence practices; through collaborative learning and teaching in mixed-age groups; through relationships …

Spatial Analysis Of Landscape Characteristics, Anthropogenic Factors, And Seasonality Effects On Water Quality In Portland, Oregon, Katherine Gelsey, Daniel Ramirez, Heejun Chang

Urban Ecosystem Research Consortium of Portland/Vancouver

Urban areas often struggle with deteriorated water quality as a result of complex interactions between landscape factors such as land cover, use, and management as well as climatic variables such as weather, precipitation, and atmospheric conditions. Green stormwater infrastructure (GSI) has been introduced as a strategy to reintroduce pre-development hydrological conditions in cities, but questions remain as to how GSI interacts with other landscape factors to affect water quality. We conducted a statistical analysis of six relevant water quality indicators in 131 water quality stations in four watersheds around Portland, Oregon using data from 2015 to 2021. E. coli and …

The Spatial Relationship Between Patterns Of Disappeared Streams And Residential Development In Portland, Oregon, Usa, Gregory C. Post, Heejun Chang, David Banis

Geography Faculty Publications and Presentations

Disappeared streams are streams that have been buried, removed, or moved as part of the urbanization process. We identified disappeared streams in the Portland, Oregon metropolitan area using historical topographic maps for four time periods, and related them to the history of urban development. The historical maps were used to identify streams visible in older maps but not shown in a more recent version. From 1852 to 1895, 15% of streams disappeared, but the majority of streams disappeared between 1896 and 1953 (65%). This trend continued mainly in suburban areas after 1954 with 12% of streams being removed from 1954 …

Does Restoration Of Urban Riparian Zones Impact Stream Water Quality In Portland, Oregon, Ash Ivanov

University Honors Theses

Riparian zones influence urban stream quality through factors such as shading the stream, adding nutrients through leaf litter, stabilizing the stream banks to reduce turbidity, and filtering toxins out of the water. Riparian restoration often involves changing plant assemblage to be more diverse and include primarily native species instead of non-native, improving connection to the stream through changing stream morphology, improving species habitat, and reducing pollution. The goal of this study was to determine if urban riparian restoration projects in the region were successful, and if not, why that may be the case. The study was performed in the Portland, …

Immigration Federalism In The United States: Constructing A Contemporary Institutional Framework Centered On Local Communities Through A Case Study Approach, Sara Kuehlhorn Friedman

Dissertations and Theses

This research study presents a new model of immigration federalism which integrates existing theories into a framework that emphasizes agency at the local level. Unlike dominant models of federalism that observe the cascading effect of higher-level policy on lower levels of government, this research focuses on empirical evidence at the local level to understand its relation to policy at higher levels. Immigration federalism is receiving substantial interest in scholarly work and in practice, but it lacks a cohesive and comprehensive theory explaining variation at the community level. There is little reason to expect sweeping changes in immigration policy at the …

Disentangling The Last 1,000 Years Of Human–Environment Interactions Along The Eastern Side Of The Southern Andes (34–52°S Lat.), William Nanavati, Cathy Whitlock, Maria Eugenia De Porras, Adolfo Gil, Diego Navarro, Gustavo Neme

Geography Faculty Publications and Presentations

Researchers have long debated the degree to which Native American land use altered landscapes in the Americas prior to European colonization. Human–environment interactions in southern South America are inferred from new pollen and charcoal data from Laguna El Sosneado and their comparison with high-resolution paleoenvironmental records and archaeological/ethnohistorical information at other sites along the eastern Andes of southern Argentina and Chile (34–52°S). The records indicate that humans, by altering ignition frequency and the availability of fuels, variously muted or amplified the effects of climate on fire regimes. For example, fire activity at the northern and southern sites was low at …

Visualizing Connectivity For Wildlife In A World Without Roads, Catherine De Rivera, Leslie Bliss-Ketchum, Martin Lafrenz, A. V. Hanson, L. E. Mckinney-Wise, A. H. Rodriguez, J. Schultz, Alana Simmons, D. Taylor Rodriguez, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

Roads are not the only determining factor for wildlife movement across the landscape, but due to the extensive distribution of the road network their impact can be dramatic. Although it has been well documented that roads decrease habitat connectivity for wildlife due to animal-vehicle collisions, habitat fragmentation, and avoidance behavior, approaches for identifying connectivity across the landscape often do not fully examine the barrier effect of roads. Here, we explored the extent of the impact of roadways on wildlife connectivity by using Omniscape to model connectivity including and without the barrier effect of roads, then evaluating the difference between these …

Portland, Portland State, And The Urban University Idea, Kimberly Nightingale, Ethan Seltzer

Historical Articles and Essays

The year 2022 marked the 50th anniversary of the City of Portland's 1972 Downtown Plan, one of the most consequential plans in the city's history. It put in place a vision for a public, pedestrian-scaled, multipurpose, and vital downtown.

Through the requirements adopted in the Downtown Plan and subsequent public and private investments stemming from it, Portland's core area became an international icon for central city recovery. That plan also formally identified Portland State University as the city's "urban university."

This paper begins with an examination of the history of the urban university idea in the United States, followed by …

Helminths Of Thomomys Species (Rodentia: Geomyidae) Of Oregon, Malorri Rene Hughes

Dissertations and Theses

Although often viewed as inconsequential, parasites have significant ecological and evolutionary importance, and studying them can generate knowledge regarding their environments and their hosts. Helminths (intestinal parasites) infecting Western pocket gophers (Thomomys species) in Oregon had been documented based only on morphology prior to this study. Basing parasite identification solely on morphology is problematic because the characteristics used to identify species can be vague or similar, leading to misidentification or obscuring the true biodiversity present. Using molecular markers to verify species present not only is more reliable but also can be informative in terms of the host-parasite association. To …

Reckoning With Induced Vehicle Travel, Jamey Volker

PSU Transportation Seminars

Empirical research shows that expanding roadway capacity induces more driving - the so-called "induced travel" phenomenon. However, environmental impact assessments and cost-benefit analyses of roadway capacity expansion projects have historically ignored, underestimated, or misestimated this induced travel effect. As a result, they frequently overestimate the projects' potential to relieve congestion and reduce air pollution. That spurred our team at the National Center for Sustainable Transportation (UC Davis) to develop an online tool to facilitate estimation of induced vehicle travel from capacity expansion projects. This presentation will explain the induced travel phenomenon, introduce our induced travel calculator and its offshoots, …

Space And Identity In J.M. Coetzee's Life & Times Of Michael K, Joshua Baker

University Honors Theses

Occupying colonial governments establish and maintain power through the demarcation and control of space, a process Sara Upstone terms "overwriting". In Life & Times of Michael K, Coetzee imagines the complication of establishing and maintaining a self-identity amid the strict control of space in post-apartheid, wartime South Africa, and it is this conflict of identity which comprises the novel’s subplot. The reader follows Michael K's odyssey over hundreds of miles in his quest to find the farm on which his mother was born and raised. His journey is repeatedly thwarted by state actors who enforce a strict control of movement …

Delving Into Institutional Diversity Messaging A Cross-Institutional Analysis Of Student And Faculty Interpretations Of Undergraduate Experiences Of Equity, Diversity, And Inclusion In University Websites, Joanna C. Rankin, Andrew Pearl, Trina Jorre De St Jorre, Moriah Mcsharry Mcgrath, Sarah Dyer, Multiple Additional Authors

Urban Studies and Planning Faculty Publications and Presentations

Recognizing that university statements about equity, diversity, and inclusion are often cosmetic, performative, or at best, aspirational, rather than indicative of on-campus realities, this project analyzes interpretations of student identity and diversity through publicly available materials. The primary purpose of this research was to investigate how university messages about equity, diversity, and inclusion, available through public websites, are interpreted by faculty and students. Using a students-as-partners approach, we identified and analyzed themes based on our own perceptions and understandings of each of five university websites University of Calgary (Canada), University of Alabama (USA), Deakin University (Australia), University of Exeter (UK), …

The Use Of Socio-Spatial Data For Sustainable Roads Planning: A National Forest Case Study, Lee Cerveny, Rebecca Mclain, David Banis, A. Todd

Geography Faculty Publications and Presentations

National forest roads allow access to public lands providing connections to natural and cultural heritage. Planning processes that address potential road closures or conversions can be highly contentious. Public participatory GIS (PPGIS) has been used as a tool to gather information for environmental planning and decision-making. Our PPGIS approach in a national forest in Washington (USA) incorporated workshops and online engagement with 1,810 participants to gather public input for sustainable roads planning. We identified the most important forest destinations and developed an analytical framework for assessing forest roads based on the density and diversity of use. In this paper, we …

The Impact Of New Light Rail Service On Employment Growth In Portland, Oregon, Lahar Santra

Dissertations and Theses

This study quantitatively examines the impact of the new Light Rail Transit (LRT) service on employment growth in retail, knowledge, and service sectors before and after opening the LRT. At the corridor level, this study conducts a case study of Greenline in Southeast Portland, Oregon. The results of the corridor level study suggest that the new LRT service increased employment along the Greenline corridor among all the three sectors of interest- retail, knowledge, service in the long-term (ten years) while having slightly different results for the short-term (five years), likely due to the slow growth of LRT benefits. This study …

Spatial And Seasonal Variations Of Microplastic Concentrations In Portland's Freshwater Ecosystems, Rebecca Talbot

Dissertations and Theses

Microplastics are a pollutant of growing concern and are ubiquitous in a variety of environmental compartments. The majority of microplastics research to date has been conducted in marine waters, and less is known regarding the sources and delivery pathways of microplastics in urban rivers. The first chapter is comprised of a review of the scientific literature regarding the spatial and temporal factors affecting global freshwater microplastic distributions and abundances. Microplastic spatial distributions are heavily influenced by anthropogenic factors, with higher concentrations reported in regions characterized by urban land cover, high population density, and wastewater treatment plant effluent. Temporal variables of …

Heat, Wildfire And Energy Demand: An Examination Of Residential Buildings And Community Equity, Chrissi Argyro Antonopoulos

Dissertations and Theses

Extreme heat and wildfire events are becoming more prolific and exacerbated by climate change, carrying significant implications for environmental and social systems. Residential buildings play a central role in protecting people from heat and pollutant exposure during extreme weather events, but the level of protection varies dramatically depending on building energy efficiency and technology availability. Low-income and communities of color have higher energy burdens compared to affluent populations, and underserved communities often do not have financial resources for, or access to, advanced building technologies. This dissertation explores the impacts of extreme heat and wildfire on residential buildings, focused specifically on …

Geographies Of Urban Unsafety: Homeless Women, Mental Maps, And Isolation, Jan Radle Roberson

Dissertations and Theses

This study explores the intersection of urban unsafety and the marginalized population of homeless women. Specifically, it investigates how homeless women identify/perceive and navigate unsafe urban space. Specific research questions include:

1. What does housing insecurity look like for an unhoused woman?

2. In what ways is mental mapping a robust tool for gathering the stories (data) of vulnerable populations such as unhoused women?

3. What does the spatialization of unsafe locations look like and are demographic groupings dissimilarly affected?

4. What are the critical reasons for unsafety identified by participants?

5. How do homeless women respond to urban unsafety; …

Never Ask For A Lighter Rain But A Stronger Umbrella, Anurag Pande, Melissa Haeffner, Günter Blöschl, Mohammad Faiz Alam, Cyndi Castro, Giuliano Di Baldassarre, Fanny Frick-Trzebitzky, Rick Hogeboom, Heidi Kreibich, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

In a recent editorial in the journal Nature Sustainability, the editors raised the concern that journal submissions on water studies appear too similar. The gist of the editorial: “too many publications and not enough ideas.” In this response, we contest this notion, and point to the numerous new ideas that result from taking a broader view of the water science field. Drawing inspiration from a recently hosted conference geared at transcending traditional disciplinary silos and forging new paradigms for water research, we are, in fact, enthusiastic and optimistic about the ways scientists are investigating political, economic, historical, and cultural intersections …

Navigating Urban Spaces: Indoor & Outdoor Wayfinding Technology For Vision-Impaired People, Martin Swobodzinski, Amy T. Parker

TREC Project Briefs

Navigating an unfamiliar place is uniquely challenging for people with disabilities. People with blindness, deafblindness, visual impairment or low vision, as well as those who use wheelchairs, can travel more independently in urban areas with the aid of effective wayfinding technology. A new report from the National Institute for Transportation and Communities (NITC) explores how to leverage low-cost methods to enable people to more easily move through public, urban indoor and outdoor spaces.

The study, led by Martin Swobodzinski and Amy Parker of Portland State University, used focus groups, two case studies, and an in-person structured wayfinding experience on the …

Oregon's Safe Harbor For Tenants: Rocky Shoals In Eviction Diversion, Lisa K. Bates

Homelessness Research & Action Collaborative Publications and Presentations

In an effort to mitigate the impacts of the Covid-19 public health emergency, throughout 2020 and into 2021 novel public health emergency programs were initiated, including a variety of federal, state, and local ‘moratoriums’ on residential evictions for nonpayment of rent. As the moratoria began to sunset, additional ‘post-pandemic’ eviction diversion and tenant protection programs were created to buffer the ‘tsunami’ of evictions that were expected.

Oregon’s eviction diversion program, the so-called ‘safe harbor period’ for nonpayment eviction cases, was put into place in July 2021 to maintain some protections for tenants after the state moratorium on nonpayment evictions ended. …

Variation In Spanish/S: Overview And New Perspectives, Eva NúÑEz-MéNdez

World Languages and Literatures Faculty Publications and Presentations

The natural tendency for language variation, intensified by Spanish’s territorial growth, has driven sibilant changes and mergers across the Spanish-speaking world. This article aims to present an overview of the most significant processes undergone by sibilant /s/ in various Spanish-speaking areas: devoicing, weakening, aspiration, elision, and voicing. Geographically based phonetic variations, sociolinguistic factors, and Spanish language contact situations are considered in this study. The sibilant merger and its chronological development in modern Spanish, along with geographic expansion, have resulted in multiple contemporary dialectal variations. This historical lack of stability in these sounds has marked modern regional variations. Tracing and framing …

Building Roseburg Public Library’S Community Demographics Dashboard, Spencer Keller

Masters in GIS Practicum Reports

In a globally connected society becoming increasingly reliant on data, community GIS practitioners help bring spatial data to community organizations and other community partners in the form of data acquisition, collection, analytics, visualization, and presentation. Many Community GIS practitioners help their community partners better serve their community by harnessing the power of GIS, including community partners who advocate for and provide services to their community. Public libraries are one such service-providing entity that has been struggling in modern times, especially in rural areas. The Center for Geography Education in Oregon received grant funding in 2020 from the Institute of Museum …
