Oregon librarians recognize the need to secure patrons’ online privacy but also want to meet …

Post Covid-19 Exit Strategies And Emerging Markets Economic Challenges, Joshua Aizenman, Hiro Ito

Economics Faculty Publications and Presentations

We study emerging markets’ 1980s lost growth decade, triggered by the massive reversal of the snowball effect in the US during 1974–1984, finding that higher flow costs of servicing debt overhang explain the dramatic decline in growth rates of exposed emerging markets. We also show how lowering the US cost of servicing its public debt has been associated with higher US, Japan, and Western Europe real output growth rates during the post WWII recovery decades, 1946–1956, and validate that fiscal adjustments of large countries have strong growth and volatility spillovers effects on exposed emerging markets and developing countries.

A Requiem For “Blame It On Beijing” Interpreting Rotating Global Current Account Surpluses, Menzie David Chinn, Hiro Ito

Economics Faculty Publications and Presentations

Global current account imbalances have reappeared, although the extent and distribution of these imbalances are noticeably different from those experienced in the middle of the last decade. What does that recurrence mean for our understanding of the origin and nature of such imbalances? Will imbalances persist over time? Informed by empirical estimates of the determinants of current account imbalances encompassing the period after the global recession, we find that – as before – the observable manifestations of the factors driving the global saving glut have limited explanatory power for the time series variation in imbalances. Fiscal factors determine imbalances, and …

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, …

Exploring Stress Relief Methods And The Efficacy For The Houseless At Urban Settings, Lexis Bates

University Honors Theses

When the word "stress" is mentioned to lay people, they might think that their definitions of "stress" would be the same or similar. However, stress may vary by, not only degrees of the adverse circumstances, but also kinds of stressors which make an individual's experience of stress and their coping mechanisms complicated. Stress refers to a state of mental strain or tension resulting from adverse circumstances. Each individual living in society undergoes stress as a part of life. To some degree, stress keeps us motivated to stay alive in this way through survival instincts. However, excess stress may cause chaos …

Enhancing Exchange Of Knowledge On The Practice Of Applied Behavior Analysis, Harper C. Thomas

University Honors Theses

Applied behavior analysis (ABA) - originally a method of studying behavior - is now an intervention style that utilizes operant conditioning and behaviorism to teach and address behaviors that support the development of autistic students. While much of ABA is strongly supported by research, a debate exists over its use. Criticisms from people on the spectrum, their families, and professionals of various fields target everything from ABA’s implementation, research, and ethical basis. By clarifying what ABA entails, reviewing the history of ABA, compiling criticisms, and collecting opinions of Oregon-based behavioral specialists, this thesis seeks to identify regions where ABA can …

Children are brought into this world under many different circumstances and to many different families. Some are planned, some are not; all come from families with a range of income, relationship status, and experiences. Throughout a child's life, there can be many changes in the family unit that impact the ways parents are available to care for their children. This includes divorce/separation, incarceration, co-parenting, married life, etc., relationship statuses may change over time. Different life stressors impact the financial wellbeing of a family and parents’ ability to spend time with their children. This study used secondary data analysis of the …

Perversion: A Genealogy Of Deviance And Creation Of The "Other", J D. Lyell

University Honors Theses

Drawing from Thomas Aquinas' Theory of Natural Law, I investigate Euro-Christian conceptions of naturalness and unnaturalness and how they were weaponized to cast racialized groups as perverse in the construction of the United States. I focus on the enforcement of Euro-heteropatriarchy to demonize Indigenous family and gender structures, as well as the characterization of Black bodies as abnormal by white academia to demonstrate some of the ways gender and sexuality have been colonized in the U.S. My research provides a general outline tracing a genealogy of deviance as established by Euro-Christian norms of sexuality and gender, which emerges from a …

A Literary Examination Of The Efficacy Of Zoological Conservation In The United States Versus Foreign Efforts, Madeleine M. Lecorre

University Honors Theses

Falling into the top four threats to biodiversity, human activity is impacting species around the globe like never before. Zoological conservation of threatened species aids in the support and reestablishment of these dwindling populations. The examination of conservation work done in the U.S compared to foreign efforts provides insight into strengths, reveals weaknesses, and will help us better serve threatened species around the world. The status of conservation in the U.S. as well as foreign efforts were assessed through literary review of published reports from accredited organizations. As zoologic conservation aims to conserve threatened species, it is also important to …

"Real" Marketing Within The Fast Fashion Industry: An Analysis Of Internal Vs. External Dei Practices, Marinda Lynn Carlyle

University Honors Theses

This thesis will analyze the social media marketing (SMM) practices of Fast Fashion industry trends that have surfaced due to recent events. Specifically, this work will compare customer-facing SMM efforts related to diversity, equity, and inclusion (DEI) initiatives against the internal values and practices a company expends towards these efforts. This thesis will use H&M as an illustrative example in representing a company within the Fast Fashion industry. The motivation of this thesis or[i]ginates from the ongoing shifts in corporate SMM practices after the murder of George Floyd in May of 2020 and the corresponding increase in social justice activism …

Genome-Wide Identification Of Novel Srnas In Streptococcus Mutans, Madeline Claire Krieger, Justin Merritt, Rahul Raghavan

Biology Faculty Publications and Presentations

Streptococcus mutans is a major pathobiont involved in the development of dental caries. Its ability to utilize numerous sugars and to effectively respond to environmental stress promotes S. mutans proliferation in oral biofilms. Because of their quick action and low energetic cost, non-coding small RNAs (sRNAs) represent an ideal mode of gene regulation in stress response networks, yet their roles in oral pathogens have remained largely unexplored. We identified 15 novel sRNAs in S. mutans and show that they respond to four stress-inducing conditions commonly encountered by the pathogen in human mouth: sugar-phosphate stress, hydrogen peroxide exposure, high temperature, and …

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 …

Marginality In Inquiry-Based Science Learning Contexts: The Role Of Exclusion Cascades, Karlyn Adams-Wiggins, Julia Sara Dancis

Psychology Faculty Publications and Presentations

Vygotskyan-inspired theories of learning have been applied in science education research, yet to more explicit attention to links between local social interactions and cultural-historical processes is needed advance critical theories of science learning. This microgenetic case study examined identity and motivation processes in a 7th grade inquiry science context with the goal of better historicizing these processes by describing the phenomenon of exclusion cascades in relation to two backgrounded cultural-historical processes, alienation and the social division of labor. Exclusion cascades highlighted the mutual constitution of competence and belonging. Implications are discussed with respect to challenging adaptationist ethos in science education.

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 …

Measurement Of Fruit And Vegetable Intake Incorporating A Diversity, Equity, And Inclusion Lens. Comment On Di Noia, J.; Gellermann, W. Use Of The Spectroscopy-Based Veggie Meter® To Objectively Assess Fruit And Vegetable Intake In Low-Income Adults, Carmen Byker Shanks, Betty Izumi, Courtney A. Parks, Amy L. Yaroch

OHSU-PSU School of Public Health Faculty Publications and Presentations

Disparities in fruit and vegetable intake (FVI) and diet-related diseases exist among low-income and racial/ethnic minority populations [1,2,3,4]. Intervention approaches to eliminate FVI disparities frequently utilize dietary assessment to measure impact. Studies measure FVI in varying ways, but do not fully account for diversity, equity, and inclusion (DEI).

Webinar: Is Transit-Oriented Development Affordable For Low And Moderate Income Households?, Reid Ewing, Justyna Kaniewska

TREC Webinar Series

Transportation and land use planning, as a field, is shifting away from segregated uses connected by highways and streets to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought special attention to transit-oriented developments (TOD), which are sometimes touted as being among the most affordable, efficient places to live. But how affordable are they, and who has the power to effect change? This study examines housing costs for households living in TODs.

Variability Of Potential Soil Nitrogen Cycling Rates In Stormwater Bioretention Facilities, Erin N. Rivers, Jennifer L. Morse

Environmental Science and Management Faculty Publications and Presentations

Low-impact development (LID) is a common management practice used to infiltrate and filter stormwater through vegetated soil systems. The pollutant reduction potential of these systems is often characterized by a single pollutant removal rate; however, the biophysical properties of soils that regulate the removal of pollutants can be highly variable depending on environmental conditions. The goal of this study was to characterize the variability of soil properties and nitrogen (N) cycling rates in bioretention facilities (BRFs). Soil properties and potential N cycling processes were measured in nine curbside bioretention facilities (BRFs) in Portland, OR during summer and winter seasons, and …

Virtual Voices: Examining Social Support Exchanged Through Participant-Generated And Unmoderated Content In A Mobile Intervention To Improve Hiv Antiretroviral Therapy Adherence Among Gbmsm., Christina J. Sun, Thembekile Shato, Ashlynn Steinbaugh, Sharanya Pradeep, K Rivet Amico, Keith Horvath

OHSU-PSU School of Public Health Faculty Publications and Presentations

Antiretroviral therapy (ART) adherence is suboptimal among gay, bisexual, and other men who have sex with men (GBMSM). Online interventions that incorporate social support represent new opportunities to improve adherence. This study focused on how social support was provided and sought within a technology-based ART adherence intervention. We coded and analyzed 1,751 messages. Within the social support messages, half of the time participants sought social support and half of the time they provided social support. Emotional and informational support were the most frequently exchanged forms. The most frequent topic that participants sought support around was interpersonal relationships (29%), followed by …

Exploring Student Perceptions Of Behavioral, Cognitive, And Emotional Engagement At The Activity Level In General Chemistry, Nicole Naibert, Elizabeth Vaughan, Kylee M. Brevick, Jack Barbera

Chemistry Faculty Publications and Presentations

Although active learning strategies are being incorporated into many higher-education STEM courses, not all students benefit from these activities to the same extent. As these types of activities are designed to engage students in their learning, differences in student engagement may explain some of the differences in learning outcomes. However, before student engagement in active learning activities can be meaningfully measured using a self-report survey, it is important to evaluate if students perceive engagement similarly to the literature definitions on which these measures are based. Therefore, this study sought to explore students’ perceptions of the behavioral, cognitive, and emotional dimensions …

Development And Evaluation Of A Survey To Measure Student Engagement At The Activity Level In General Chemistry, Nicole Naibert, Jack Barbera

Chemistry Faculty Publications and Presentations

Student engagement is an important consideration when incorporating active learning activities into a classroom. To facilitate the large-scale assessment of students’ engagement in activities, a survey measure must first be developed and evaluated. Therefore, the goal of this study was to create a self-report measure of student engagement for use with active learning activities in general chemistry classes. The Activity Engagement Survey (AcES) was modified from an existing survey of engagement of middle and high school science students that contained behavioral, cognitive, emotional, and social engagement items. Multiple rounds of response process interviews and factor analyses were used to modify …

Bwana, David Bangsberg, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Introduction: Antiretroviral pre-exposure prophylaxis (PrEP) may reduce periconception and pregnancy HIV incidence among women in settings, where gender power imbalances limit HIV testing, engagement in care and HIV viral suppression. We conducted qualitative interviews to understand factors influencing periconception and pregnancy PrEP uptake and use in a cohort of women (Trial registration: NCT03832530) offered safer conception counselling in rural Southwestern Uganda, where PrEP uptake was high. Methods: Between March 2018 and January 2019, in-depth interviews informed by conceptual frameworks for periconception risk reduction and PrEP adherence were conducted with 37 women including those with ≥80% and

Per-Person And Whole-Building Voc Emission Factors In An Occupied School With Gas-Phase Air Cleaning., Brett W. Stinson, Aurélie Laguerre, Elliott T. Gall

Mechanical and Materials Engineering Faculty Publications and Presentations

Using real-time measurements of CO and volatile organic compounds (VOCs) in the air handler of an occupied middle school, we quantified source strengths for 249 VOCs and apportioned the source to the building, occupants and their activities, outdoor air, or recirculation air. For VOCs quantified in this study, there is a source to the outdoors of 8.6 ± 1.8 g/h in building exhaust air, of which 5.9 ± 1.7 g/h can be attributed to indoor sources (the building and occupants and their activities). The corresponding whole-building area emission factor from indoor sources is 1020 ± 300 μg/(m h), including reactive …

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 …
