Understanding Water Security In Portland, Oregon: Using Newspapers As Tools For Science Communication And Education, Julian Roth

University Honors Theses

Water insecurity is faced by a large percentage of the global population, particularly in urban areas, which face greater and more complex needs for water resources. Better tools are needed to be able to recognize and communicate water security issues in a way that reinforces water systems, engages all stakeholders, and recognizes early warnings of environmental injustice. This research examines utilizing public newspaper articles to produce these tools. Using a case-study approach, this thesis explores newspaper articles about water from 2014-2020 in the urban center of Portland, Oregon, to understand local water security issues and to build a system of …

Launching The Wasatch Transportation Academy, Nathan Mcneil, Keith Bartholomew, Matthew Ryan

TREC Final Reports

The “Community Transportation Academy” model seeks to break down the barriers for community members to participate in transportation decision-making processes. Since 1991, the Portland Traffic and Transportation Course has held at least one course each year, connecting Portland residents with top planners, engineers, and decision-makers from agencies working on transportation in the region, with the goal of conveying the factors professionals consider, ranging from technical considerations, legal and policy mandates, other tradeoffs, and how the community can engage with and influence decisions. This project sought to implement a transportation academy in the Salt Lake City region inspired by the Portland …

Congested Sidewalks: The Effects Of The Built Environment On E-Scooter Parking Compliance, Rob Hemphill, John Macarthur, Phil Longenecker, Garima Desai, Lillie Nie, Abbey Ibarra, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

With the proliferation of electric scooters (e-scooters) in cities across the world, concerns continue to arise about their parking spots on sidewalks and other public spaces. Research has looked at e-scooter parking compliance and compared compliance to other mobility devices, but research has not yet examined the impacts of the built environment on parking compliance. Using a field observation dataset in Portland, Oregon, and novel GIS data, we attempt to understand the spatial distribution of e-scooter parking and the impact of built features on parking compliance, offering recommendations for policymakers and future research. The results of our study show that …

No History Or Society To Be Found: Object-Oriented Ontology And Social Ontology, Bennett B. Gilbert

University Studies Faculty Publications and Presentations

It is widely theorized that the advent of the “Anthropocene Age” (under this or any other name) is bringing one form of human temporality to an end while it initiates another (Simon 2021). Because human activity threatens the duration and well-being of the planetary biosphere, the new age that this activity is bringing on—though it is proving to be extremely difficult to define—does present specific onto-epistemological and moral challenges behind its political and social problems. The most prominent and perhaps the core of these challenges is the demand to shed anthropocentrism in human culture, a change that would deeply alter …

A New Studio Era: How Netflix Is Becoming A Threat To The Film Industry, Al Kasper

University Honors Theses

Movie streaming services have become an increasingly popular distribution method due to their widespread accessibility to film content across the globe. Netflix is the biggest competitor of movie streaming services and has led the charge in creating original content for its customers. With many of these streaming services creating their own content, both Hollywood and independent studios are being introduced to a new competitor in their market: studios that stream their own content. While this may seem to be an issue only within the industry, there are concerns about another oligarchy of studios being created out of these streaming services …

Equilibria: Sustainability And Eco-Awareness In Music Production, Ashley A. Kahl-Placek

Mathur, Akshay Shanker, Lena Novack, Ruth Pérez-Robles, Kim A. Hoffman, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Yoga practices, including breathing, meditation, and posture protocols (asanas), have been shown to facilitate physical and mental wellbeing.

Methods: Seasoned yoga practitioners were recruited from the Isha Foundation. Recruitment of the comparison group was achieved using snowball sampling and were not yoga practitioners. Participants in the non-yoga group were randomized to a 3-min Isha practice or a comparator group asked to perform 15-min of daily reading. Participants completed a series of web-based surveys (REDCap) at baseline, 6, and 12 weeks. These surveys include validated scales and objective questions on COVID-19 infection and medical history. The validated questionnaires assess for: …

Leaving College Without A Degree: The Student Experience At An Urban Broad Access Institution, Andrea Marie Garrity

Dissertations and Theses

This thesis seeks to understand how students who leave college without a degree, or non-completers, experience broad access institutions in an effort to shift our thinking from the student characteristics that predict college dropout to how broad access institutions can better serve students and improve graduation rates. To answer this question, I conducted interviews with former students who had recently attended a broad access institution and left without a degree. Results show that participants expressed internalized views of the traditional college student archetype, which was reinforced through their college experience. Further, participants encountered significant bureaucratic challenges and barriers, and expressed …

Modeling Environment For Testing A Distributed Energy Resource Management System (Derms) Using Gridapps-D Platform, Shiva Poudel, Sean Keene, Roshan Kini, Sarmad Hanif, Robert B. Bass, Jaime Kolln

Electrical and Computer Engineering Faculty Publications and Presentations

The electric power system is currently undergoing a major transition due to growing numbers of distributed energy resources (DERs) and increased distribution automation. If optimally managed and operated, DERs could provide flexibility and highly valuable grid services such as restoration, peak shaving, voltage regulation, and frequency support to maintain grid reliability. Different applications and enterprises, such as distributed energy resources management systems (DERMS), are being developed for coordinated and optimal operation of DERs. However, to attract sufficient DER participation and achieve the coordinated operation of DERs, systems and components must be interoperable and information exchange must be secure. Along this …

Knowledge Overconfidence Is Associated With Anti-Consensus Views On Controversial Scientific Issues, Nicholas Light, Philip M. Fernbach, Nathaniel Rabb, Mugur V. Geana, Steven A. Sloman

Business Faculty Publications and Presentations

Public attitudes that are in opposition to scientific consensus can be disastrous and include rejection of vaccines and opposition to climate change mitigation policies. Five studies examine the interrelationships between opposition to expert consensus on controversial scientific issues, how much people actually know about these issues, and how much they think they know. Across seven critical issues that enjoy substantial scientific consensus, as well as attitudes toward COVID-19 vaccines and mitigation measures like mask wearing and social distancing, results indicate that those with the highest levels of opposition have the lowest levels of objective knowledge but the highest levels of …

Writing New Lives, Writing New Worlds, A. Zed

Amplify: A Journal of Writing-as-Activism

Creative nonfiction. Children are learning to write their letters. Adults are learning to write their feelings. All of us are learning to write our stories, and thereby release some of the trauma circling through our world.

3 Selections From "Upon The Body: Poems Of/To A Black Social Epi, Pt.Ii--Love//Resistance In The Time Of Covid", R. J. Petteway

Amplify: A Journal of Writing-as-Activism

The 3 poems included here are from a collection written between January and August 2020. The full collection—27 poems total—examines intersections of structural racism, racialized police violence, and COVID-19, drawing from generations of creative resistance produced and embodied by Black artists, activists, and scholars like Nina Simone, Langston Hughes, Paul Laurence Dunbar, Audre Lorde, Ida B. Wells, James Baldwin, and W.E.B. DuBois. The collection as a whole is crafted as counternarrative to public health’s ahistoric, apolitical, racist, and homophobic proclivities in times of crisis. The 3 poems here are from Part II, "LOVE//Resistance in the Time of COVID.” These selections …

Public History Is Now, Sarah E. Dougher

Amplify: A Journal of Writing-as-Activism

A walking tour of downtown Portland in August 2021 raises questions for the writer about the purpose of “memory activism,” its relation to writing-as-activism. Drawing on critiques of urbanist Jane Jacobs and interrogating the concept of “reckoning,” the essay explores ways in which the streetscape and people there can deliver meaning and pose questions about systemic racism and unsheltered existence.

Framing The Green New Deal And Climate Change: A Content Analysis Of The New York Times And The Wall Street Journal, Danielle Elizabeth Duffy

Dissertations and Theses

The importance of climate change recognition and need for action cannot be overstated. Climate change has historically been a partisan issue with an almost hyper focus on the (un)certainty of science, the need for action within a particular timeframe, and the cost of tackling the issue. With the contemporary relevance and salience of climate change, this content analysis explores emerging framing patterns in coverage of the Green New Deal and subsequent climate change references within news articles from the New York Times and Wall Street Journal in 2019. Frame typology from O'Neill et al. (2015) is used to explore the …

High School Persisters And Alternative Schools, Hyuny Clark-Shim

Dissertations and Theses

In response to a "dropout crisis," over the past decade much effort was made to retain high school students. Recent years' trends indicated an overall increased level of graduation rates; however, there has been a largely overlooked student population, persisters, who did not earn a high school diploma by the expected graduation date but remain engaged and continue to work towards graduation into their fifth or even sixth year of high school.

Using exploratory CART analysis, this study examined what individual-level and school-level factors were most effective in distinguishing students who were persisters versus on-time graduates. Given that persisters …

Toward Analyzing The Diversity Of Extractive Summaries, Aaron David Hudson

Dissertations and Theses

As the amount of text generated across the internet continues to increase, developing methods for processing that text to glean valuable insights is paramount. Automatic text summarization is one such method that aims to provide a concise and representative summary of input text, allowing users access to the most salient points from a large amount of textual data. However, in working with these summaries, especially those generated from social media data, questions arise about not only the quality of a summary, but also its ability to reflect the diversity of user perspectives. This work examines the quality of summaries with …

Gender Equity And State-Mosque Relations In Middle East North Africa: A Case Study Of Tunisia, Joy Amarachi Agbugba

Dissertations and Theses

Why is the Middle East North Africa region consistently ranked the lowest on the gender equity scale? This question is quite perplexing and that has driven several scholarly researchers to investigate the situation of gender and women's rights within the states in the region. In this research, I explore the various theories explaining the cause of gender inequity in this region including the Islam thesis/social modernization theory, political-economic theory, and psychological/social structural theories, with an emphasis on the Islamic thesis theory. I argue that the state's support and prioritization of Muslim/sharia law over federal law is a major contributor to …

"Damn, Man. The Time That I Lost": Power And The Process Of Diagnosis For Women With Chronic Illnesses, Kaitlin Roquel Yeomans

Dissertations and Theses

Historical sociological research on people with chronic illness has examined their navigation of their lives post-diagnosis. Diagnosis has been considered with regard, not to its process, but rather to its definitions. While a rich literature has been produced by such approaches, how people experience the process of diagnosis has largely been ignored. This research looks at the process of diagnosis as a series of moments, all of which hold specific meaning in the interactional context of the patient-provider relationship. Looking at diagnosis from the patient’s perspective demonstrates how information about health and illness is exchanged, navigated, and negotiated. Importantly, this …

The Case For Mandatory Reporting As An Ethical Dilemma For Social Workers, Sam Harrell, Stéphanie Wahab

School of Social Work Faculty Publications and Presentations

Mandatory reporting of child abuse is a part of the civil legal system that can activate a policy cascade disproportionately criminalizing racialized and marginalized communities. While social work scholarship has explored ways to increase provider compliance with mandatory reporting laws, there is a dearth of research focused on how social work education guides future providers towards the praxis of mandatory reporting discourses. This article presents findings from a content analysis of social work textbook excerpts focused on mandatory reporting of child abuse in the U.S. We found that textbooks affirm social work’s loyalty to the State by approaching mandatory reporting …

Snerf: Stylized Neural Implicit Representations For 3d Scenes, Thu Nguyen-Phuoc, Feng Liu, Lei Xiao

Computer Science Faculty Publications and Presentations

This paper presents a stylized novel view synthesis method. Applying state-of-the-art stylization methods to novel views frame by frame often causes jittering artifacts due to the lack of cross-view consistency. Therefore, this paper investigates 3D scene stylization that provides a strong inductive bias for consistent novel view synthesis. Specifically, we adopt the emerging neural radiance fields (NeRF) as our choice of 3D scene representation for their capability to render high-quality novel views for a variety of scenes. However, as rendering a novel view from a NeRF requires a large number of samples, training a stylized NeRF requires a large amount …

An Essential Role For Tungsten In The Ecology And Evolution Of A Previously Uncultivated Lineage Of Anaerobic, Thermophilic Archaea, Steffen Buessecker, Marike Palmer, Dengxun Lai, Joshua Dimapilis, Xavier Mayali, Damon Mosier, Jian-Yu Jiao, Daniel R. Colman, Anna-Louise Reysenbach, Multiple Additional Authors

Biology Faculty Publications and Presentations

Trace metals have been an important ingredient for life throughout Earth’s history. Here, we describe the genome-guided cultivation of a member of the elusive archaeal lineage Caldarchaeales (syn. Aigarchaeota), Wolframiiraptor gerlachensis, and its growth dependence on tungsten. A metagenome-assembled genome (MAG) of W. gerlachensis encodes putative tungsten membrane transport systems, as well as pathways for anaerobic oxidation of sugars probably mediated by tungsten-dependent ferredoxin oxidoreductases that are expressed during growth. Catalyzed reporter deposition-fluorescence in-situ hybridization (CARD-FISH) and nanoscale secondary ion mass spectrometry (nanoSIMS) show that W. gerlachensis preferentially assimilates xylose. Phylogenetic analyses of 78 high-quality Wolframiiraptoraceae MAGs from …

Legislative Procedures And Perceptions Of Legitimacy, Megan Elizabeth Cox

Dissertations and Theses

While mechanisms of legitimacy development have been extensively studied in governments as a cohesive whole, procedural legitimation of the legislative branch has not been explored. Using a procedural justice framework to identify indicators of openness in legislative rules, this paper theorizes that the presence or absence of these indicators will be the key factor in public perceptions of legitimacy of the legislature. This paper hypothesizes that where more indicators are present, a legislature will be viewed as more legitimate by its citizens as compared to a legislature with fewer indicators.

Comparing Indonesia and the Philippines, two presidential democracies in Southeast …

Erasure Through Engagement: The Community Resettlement Of Isle De Jean Charles, Meghan Elizabeth Sullivan

Dissertations and Theses

The State of Louisiana and the national media have claimed that the community resettlement of Isle de Jean Charles (IDJC) is an example of a 'model resettlement' for communities experiencing the impacts of climate change. At the outset, the project was advocated and led by the tribal leadership of the Isle de Jean Charles Band of the Biloxi-Chitimacha-Choctaw Tribe. Although, through the course of the resettlement the supposed partnership between the State of Louisiana and the Tribe has dissolved. This study seeks to provide a robust and in-depth understanding of the planning and implementation process of the IDJC resettlement to …

Exploring Structure-Function Relationship In Small-Molecular Catalysts Using Computational And Experimental Methodologies, Avik Bhattacharjee

Dissertations and Theses

Molecular modeling is a useful tool in the field of catalyst design for various processes. The use of Density Functional Theory (DFT) is routine in almost every discipline of chemistry. This allows for a deeper understanding of a molecular system even in situations where implementation of an experimental technique is unfeasible. However, without the right choice of theory and insufficient description, the model becomes susceptible to produce ambiguous results. This often leads to poor correlation with experimental findings hence an incomplete understanding of the system under study. Hence, to acquire a thorough knowledge of the intricacies involved in a system, …
