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 …

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 …

The Right To Urban Streams: Quantitative Comparisons Of Stakeholder Perceptions In Defining Adaptive Stream Restoration, Chang-Yu Hong, Eun-Sung Chung, Heejun Chang

Geography Faculty Publications and Presentations

Assuring healthy streams in the urban environment is a major goal for restoration scientists, urban planners, and city practitioners around the globe. In South Korea, many urban stream restoration efforts are designed to provide safe water to society and enhance ecological functions. We examined the extent to which the individual interests and different values of multiple stakeholders were considered in previous decision-making in two urban stream restoration projects. The relevant data on stream restoration were collected through the nominal group technique (NGT) and the analytic hierarchy process (AHP) for the two stream cases of a populated inland area and a …

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 …

Reflections On Bodies And Absences In The Covid-19 Interregnum, Matthew Weinstein

Northwest Journal of Teacher Education

This is a meditation on the role of absence during the COVID-19, especially the ways absences are felt and experienced. It explores the roles of bodies as both symbols and material. Bodies are both thought through the logic of borders and difference but also as the raw resources of scientific investigations. This is all examined within and against “education” both in my and in my students’ (pre and in-service teachers) classes and our anxieties of not knowing the what or how we of our jobs in these conditions.

Determinants Of Green Purchase Intentions Of Saudi Consumers, Amani Mohammed Kaadoor

Dissertations and Theses

Much of the research on how and why consumers engage in pro-environmental consumption has occurred in the wealthy countries of the West, where green markets are increasingly well established. Research in other economic and cultural context is sparse and points to large regional differences that cause some researchers to call key theoretical foundations, such as the Theory of Planned Behavior, into question. In response, this study investigates the factors that predict green purchase intention for food and personal care products in Saudi Arabia, a wealthy country with a rapidly growing population, severe environmental challenges, and a nascent green consumer market …

Individual school forecasts consistent with the middle series are also presented for the 21 year period.

Cultivating “Indian Country”: Settler Imperialism And Bich Minh Nguyen's Pioneer Girl, Marie Lo

English Faculty Publications and Presentations

This article examines Pioneer Girl as a critical juxtaposition of the contradictions of settler imperialism. Settler imperialism denotes how the logic and operations of settler colonialism rationalize modes of conquest that are not reducible to the acquisition of territory but are central to the consolidation of settler state security and power. The novel’s use of Little House on the Prairie to explore the Lien family’s exile and displacement as a result of US imperial violence in Southeast Asia juxtaposes the histories of settler colonialism with imperialism, illuminating how the narratives that justify western expansion are not strictly territorial imperatives. The …

Greening Inequality: How Urban Sustainable Development Fails Under Neoliberalism, Josie R. Allison

University Honors Theses

Despite its banner of common-good altruism, urban sustainable development becomes a branding scheme for municipalities when it operates under and prioritizes a neoliberal agenda. Neoliberalism is the dominant economic philosophy within the United States, and other western economies, that emphasizes extreme economic liberalism and open markets with public fiscal austerity and the diminished role of governments. This has transferred a great portion of power and funding once held by the public sector into the hands of the private sector. Under neoliberalism, city governments function with stripped federal funding and limited budgets, while leaning on private companies for public operations, like …

Evaluating The Self-Determination Model For Older Youth In Foster Care: Establishing Efficacy And Exploring Moderation Of Response To Intervention, Jennifer E. Blakeslee, Laurie E. Powers, Sarah Geenen, Jessica Schmidt, May Nelson, Ann Fullerton, Kevin George, Elizabeth Mchugh, Mary Bryant

Regional Research Institute for Human Services

Limited rigorous research has been conducted to evaluate the impact of interventions designed to promote the successful transitions of young people exiting foster care. The current study builds on previous experimental evaluations of the Model (MLM) for self-determination enhancement, which demonstrated effectiveness in improving educational and transition-to-adulthood outcomes for youth in foster care with disabilities, including those with mental health challenges. The model features one-on-one youth-directed coaching and near-peer mentoring to increase self-determination and goal achievement. The current study was the first to test the impact of the model with a diverse population-based cohort of youth aged 16.5-18.5 in foster …

Comparing The Promise And Reality Of E-Scooters: A Critical Assessment Of Equity Improvements And Mode-Shift, Michael Glenn Mcqueen

Dissertations and Theses

In just three years, e-scooters have substantially disrupted and altered the urban mobility landscape. Throughout this period, they have been commonly touted as part of a larger micromobility solution that promises to erase equity barriers and solve the first-mile/last-mile problem. However, few studies in the nascent e-scooter literature have considered these claims. In this study, we surveyed students at Portland State University (n = 1,968) about the role that e-scooters, among other modes, played in meeting their general and university-related travel needs. We then estimated models that incorporated demographics, travel behavior, and latent attitudes distilled using exploratory factor analysis (EFA). …

A Scoring Model To Evaluate Offshore Oil Projects: Case Of Eni And Mellitah Oil & Gas, Abdulhakim Giadedi

Dissertations and Theses

Offshore oil projects have many different and unique characteristics, such as larger project size, higher number of scopes, and higher complexity. In fact, offshore oil projects described as mega projects are ones that require significant assessment and acquisition methods in order to reduce risks and failures. Traditionally, cash flow analysis and return on investment are the most known factors to evaluate offshore oil projects. However, there are several other internal and external factors that affect the overall performance of offshore oil projects. A comprehensive approach and advanced tools are required to evaluate these factors that can have a significant impact …

High-Severity And Short-Interval Wildfires Limit Forest Recovery In The Central Cascade Range, Sebastian Upton Busby, Kevan B. Moffett, Andres Holz

Geography Faculty Publications and Presentations

Increasing forest fuel aridity with climate change may be expanding mid-to-high-elevation forests’ vulnerability to large, severe, and frequent wildfire. Long-lasting changes in forests’ structure and composition may occur if dominant tree species are poorly adapted to shifting wildfire patterns. We hypothesized that altered fire activity may lower existing forest resilience and disrupt the recovery of upper-montane and subalpine conifer forest types. We empirically tested this hypothesis by quantifying post-fire forest structure and conifer tree regeneration after spatially large, severe, and rapidly repeated wildfires (

Rainfall Triggers More Deep-Seated Landslides Than Cascadia Earthquakes In The Oregon Coast Range, Usa, Sean R. Lahusen, Alison R. Duvall, Adam M. Booth, A. Grant, Ben A. Mishkin, David R. Montgomery, Will Struble, Joshua J. Roering, J. Wartman

Geology Faculty Publications and Presentations

The coastal Pacific Northwest USA hosts thousands of deep-seated landslides. Historic landslides have primarily been triggered by rainfall, but the region is also prone to large earthquakes on the 1100-km-long Cascadia Subduction Zone megathrust. Little is known about the number of landslides triggered by these earthquakes because the last magnitude 9 rupture occurred in 1700 CE. Here, we map 9938 deep-seated bedrock landslides in the Oregon Coast Range and use surface roughness dating to estimate that past earthquakes triggered fewer than half of the landslides in the past 1000 years. We find landslide frequency increases with mean annual precipitation but …

Urban Transportation System Flood Vulnerability Assessment With Special Reference To Low Income And Minority Neighborhoods, Courtney Crosson, Daoqin Tong, Yinan Zhang

TREC Final Reports

A flood vulnerability assessment of the City of Tucson, Arizona’s transportation systems was conducted with special reference to low-income and minority neighborhoods. Short-term flooding from extreme storm events pose a serious challenge to transportation system reliability and emergency response in cities across the United States. This problem, which is anticipated to grow over the next century due to climate change, is often hardest on vulnerable populations, including low-income and minority neighborhoods. Our work aimed to advance national research methods for assessing multi-modal transportation degradation due to flooding. We identified priority locations for Tucson to make transportation improvement investments for the …

The Almohad: The Rise And Fall Of The Strangers, David Michael Olsen

Dissertations and Theses

The Almohad (1120-1269) displaced the Almoravid dynasty (1040-1147) as the rulers of the Maghreb and Andalusia in 1147 and created the largest Berber kingdom in history. They conquered the first indigenous rulers of the Maghreb by aggregating the Masmuda tribes from the High Atlas Mountains and enlisting the Zenata and Arab tribes from the Northern Maghreb. The Almohad rule built upon the existing Almoravid infrastructure; however, their cultural, administrative, and military approach entailed a more integrated tribal organization, centralized authority, and an original Islamic ideology. In creating this empire they envisioned the Maghreb as a consolidated political center and not …

Trailblazing Transformation: Pioneering Transformative Peacebuilding In Academic Labor Conflicts, Sam Frazier Hediger

Dissertations and Theses

Unionized contingent faculty in the United States face an increasingly difficult economic landscape in their labor-management conflicts with university administrations. These unions, comprised of graduate student employees and adjunct instructors, won significant victories for their members but have failed to shift the broader patterns of casualization, unsustainable compensation, and job precarity, stemming from the systemic debasement of higher education institutions and the American labor movement, both of which pose significant challenges to conventional conflict resolution strategies. To find a path forward, this thesis explores the nature and possibility of transforming of the academic labor conflict, using a transformative peacebuilding approach …

Dissertations and Theses

The principles of Catholic Social Teaching as represented by the writings of 150 years of popes as well as the theorists inspired by those writings are examined, as well as the two principal schools of thought in the sustainability literature as represented by what is classically called the anthropocentric or managerial approach to sustainability as well as the biocentric school of thought.

This study extends previous research by analyzing what the Catholic Church has said over the course of centuries on issues related to society, economics, and the environment, as embodied in the core concepts of subsidiarity, solidarity, stewardship, the …

A Land Of Poets And Warriors: The Connection Between Warrior Culture And Bardic Culture In Medieval Wales C. 1066-1283, Sarah Lynn Alderson

Dissertations and Theses

Wales in the Middle Ages was a region both divided by war and united by culture. Frequent raids from the Hiberno-Irish, Scandinavians, and Flemish threatened Wales from the outside, while the kings within the borders of Wales fought for supremacy. During the late eleventh century, William the Conqueror made his way to the Welsh border in an attempt to secure his fledging kingdom. Under the premise of protecting his borders, William established the first March of Wales on the eastern border of Wales in 1087. This started the slow process of Anglo-Norman expansion and colonization into Wales.

The Welsh maintained …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Whoonga is a smoked heroin-based street drug that first emerged in South Africa a decade ago. While previous scientific reports suggest that use is growing and youth are particularly vulnerable, trajectories of initiation are not well characterized. Methods: In 2015, 30 men undergoing residential addiction treatment for this smoked heroin drug in KwaZulu-Natal, South Africa participated in semi-structured interviews about their experiences using the drug. Interview data were coded using qualitative content analysis. Results: Participant trajectories to initiating smoked heroin were “vertical” in the context of marijuana use or “horizontal” in the context of other hard drug use. Participants …

Variability In Historical Fire Patterns Of A Moist Mixed-Conifer Forest In The Northern Blue Mountains Of Oregon, Laura Marie Platt

Dissertations and Theses

High variability in historical fire patterns characteristic to mixed-severity fire regimes is expected to have contributed to a structurally heterogeneous landscape throughout much of the forested ecosystems of the western United States. After more than a hundred years of fire exclusion in the region, many forests have shifted to a more homogeneous structure, which raises concern regarding these forests' ability to sustain expected increases in fire activity with a warming climate. The shift is not uniform across the west, however, and differences in historical disturbance patterns and changes due to land management are not well characterized in forests across a …

Understanding Institutional, Social, And Ecological Systems Influencing Climate Change Adaptation And Water Governance In Wine Regions: A Comparative Case Study Of Oregon's Willamette Valley, Usa And Tasmania, Australia, Erin Upton

Dissertations and Theses

My research examines how water management decisions create opportunities or barriers to climate change adaptation in wine regions. Water is a critical resource for economic and environmental sustainability in wine grape growing regions. Climate uncertainty presents considerable risk and vulnerability to freshwater resources in wine producing regions where needs for access to water will increase with more frequent climate extremes. Climate adaptation in the wine industry is a complex problem that requires multi-disciplinary approaches. This research aims to strengthen the interface between water governance and technological and viticulture adaptation approaches. Water resources are shared across regions by stakeholders with varied …
