Impact Of Industrial Disasters On The Mental Health Of Vietnamese Americans On The Gulf Coast, Vivian L. Duong

OHSU-PSU School of Public Health Annual Conference

An explosion on the Deepwater Horizon oil rig caused 200 million gallons of crude oil to spill on the Gulf Coast over a five-month span. About 16,000 miles of coastline, ecosystem and marine life along Alabama, Florida, Louisiana, Mississippi, and Texas were contaminated. This disaster and the recovery process caused social, financial, and ecological shocks, resulting in adverse psychosocial and physical health outcomes, health disparities, and socioeconomic inequality. Among the oil spill's most affected and vulnerable populations are the Vietnamese American communities that settled on the Gulf Coast after the end of the Vietnam War in 1975. The plight of …

Map The System: Presence And Impact Of Ppcps In Water, Emma Vandermeulen, Ruby Mitchell

OHSU-PSU School of Public Health Annual Conference

In a changing climate, there is growing emphasis on protecting our water sources and developing systems for conserving and reusing water. While many contaminants of concern are monitored and addressed by water treatment systems, pharmaceuticals and personal care products (PPCPs) are generally not accounted for. PPCPs in water systems have been an increasing concern as detection of these products has increased over the last few decades. Studies have been exploring the impact of antibiotics, antidepressants, contraceptives, and other anthropogenic products on our water system and how these substances interact with local ecosystems. Our main research questions are to understand what …

Impacts Of Floodplain Restoration On Water Temperature And Macroinvertebrates In Whychus Creek, Oregon, Wesley Nathan Noone

Dissertations and Theses

Stream restoration is a proposed climate adaptation tool, however, outcomes of floodplain restoration on stream temperature have been debated. Despite a growing number of studies that investigated water temperature in restored streams, few have quantified thermal heterogeneity in new habitat types created by restored hydrogeomorphic processes and the impact of thermal diversity on the aquatic macroinvertebrate community. In this study, I evaluated three hypotheses: 1) restoration increases habitat diversity, 2) habitat diversity increases water temperature heterogeneity, and 3) restored reaches have more diverse macroinvertebrate communities. I collected a total of 40 macroinvertebrate samples and characterized environmental conditions in three reaches …

Beyond “Psychic Income”: An Exploration Of Interventions To Address Work-Life Imbalances, Burnout, And Precarity In Contemporary Nonprofit Work, Robbie W. Robichau, Billie Sandberg, Andrew Russo

Public Administration Faculty Publications and Presentations

Nonprofit scholars and practitioners alike adhere to a long-held assumption that nonprofit work is, and will remain, inherently meaningful work. The long-term marketization of the nonprofit sector coupled with the influence of the COVID-19 pandemic has undercut this narrative. Our research on meaningful nonprofit work indicates that while many nonprofit workers do find their work meaningful, pay, flexibility, and work/life balance are increasingly important to them. This commentary suggests that nonprofit leaders can no longer presume that workers motivated by prosocial values will seek out and stay with nonprofit work, satisfied with the “psychic income” that comes from doing good …

Detecting Fast Frequency Events In Power System: Development And Comparison Of Two Methods, Hussain A. Alghamdi, Midrar Adham, Umar Farooq, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

In power systems, frequency deviation from nominal value can occur due to reasons such as loss of generation, loss of load, or major faults in the grid. Such frequency fluctuations can lead to serious subsequent outages and damages to both end-user and utility equipment. Therefore, a proper frequency deviation detection methodology must be in place to effectively identify frequency events in a timely manner. This manuscript provides a comparative analysis between two frequency deviation detection algorithms. One is based on signal processing and statistical analysis. The other is a regression-based algorithm. Both of these algorithms have multiple adjustable parameters, making …

Trust Model System For The Energy Grid Of Things Network Communications, Narmada Sonali Fernando, Zhongkai Zheng, John M. Acken, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Network communication is crucial in the Energy Grid of Things (EGoT). Without a network connection, the energy grid becomes just a power grid where the energy resources are available to the customer uni-directionally. A mechanism to analyze and optimize the energy usage of the grid can only happen through a medium, a communications network, that enables information exchange between the grid participants and the service provider. Security implementers of EGoT network communication take extraordinary measures to ensure the safety of the energy grid, a critical infrastructure, as well as the safety and privacy of the grid participants. With the dynamic …

Metadata Decentralized: An Examination Of Folksonomy In Book Publishing, Dani Tellvik

Book Publishing Final Research Papers

Classification of materials as multifaceted and complex as books is fraught with competing needs and idiosyncratic forms of expression and organization. A publisher’s primary goal is to position their books in a way that will attract readers who find value in the books. Book Industry Standards and Communication (BISAC) codes, the list of industry-approved subject headings, are essential to a book’s metadata for North American publishers. They are used to strike the balance so that a book blends in to an established category while also standing out as a particularly compelling of unique expression or the chosen classification.

Examining The Discovery Behaviors Of Comics Consumers, Tara Mccarron

Book Publishing Final Research Papers

The comics consumer base is big and it’s only getting bigger. And yet, very little research has been done on the consumer behavior of comics reads. In order to broaden the accessibility to comics consumer research, this paper examined the discovery behavior of 56 survey participants. The survey included questions pertaining to demographics, frequency of comics consumed, genres of comics consumed, formats used to consume comics, and methods used to discover comics. Due to limited scope, this paper focused solely on format preferences, discovery preferences, and the most-popular genre preferences. Based on this research, graphic novels remained the preferred format …

Geography Faculty Publications and Presentations

Increasing fire severity and warmer, drier postfire conditions are making forests in the western United States (West) vulnerable to ecological transformation. Yet, the relative importance of and interactions between these drivers of forest change remain unresolved, particularly over upcoming decades. Here, we assess how the interactive impacts of changing climate and wildfire activity influenced conifer regeneration after 334 wildfires, using a dataset of postfire conifer regeneration from 10,230 field plots. Our findings highlight declining regeneration capacity across the West over the past four decades for the eight dominant conifer species studied. Postfire regeneration is sensitive to high-severity fire, which limits …

The Impressionist Impact: How Claude Debussy Influenced Non-Western Composers And Music, Ragan Love

University Honors Theses

Achille-Claude Debussy (1862-1918) was a French composer and a pioneer in Impressionist music and experimented with an original system of harmony which would shape music for the rest of the 20th century. His work would go on to impact the compositional style of two other composers, Toru Takemitsu (1930-1996), a Japanese composer, and Herbie Hancock (1940- ), a jazz performer and composer. Throughout this project you will see the influence that Debussy had on these other composers through a multimedia experience with scores and recordings. Debussy's use of chromaticism and modal melodies are big contributors to the music of Takemitsu …

Towards Data And Solution-Focused Approaches For Homeless Populations On Publictransit, Anne Nordberg, Jaya Davis, Stephen Mattingly, Nithisha Gudipati, Ebonie Kinney, Hadiisha Butts

TREC Final Reports

People experiencing homelessness frequently rely on public transit systems and facilities as more than a mode of transportation to needed services, but also as safe shelters from weather and danger. This is a challenge for many transit agencies and impacts transit employees and passengers. Dallas and the surrounding counties have the largest homeless population in Texas, and they utilize the services of the Dallas Area Rapid Transit (DART) that serves 220,000 people per day in Dallas County and 12 surrounding counties. While there is much research focused on people experiencing homelessness, there are gaps in understanding how this population utilizes …

Do Travel Costs Matter For Persons With Lower Incomes? Using Psychological And Social Equity Perspectives To Evaluate The Effects Of A Low-Income Transit Fare Program On Low-Income Riders, Katharine Mcmahon, Morgan Taylor, Liu-Qin Yang, Liming Wang, Aaron Golub, Greg Townley

TREC Final Reports

Objective: Access to transit can deliver a host of benefits to the riders and to the region. Previous research aiming to study these benefits has primarily relied on data collected from the opening of new routes or transit systems and focused on the general population. Little is known how low-income riders (LIR) react and benefit in response to when the cost barrier to access to transit is removed. With an intention to increase ridership while addressing the needs of transit-dependent riders in the region, TriMet (Portland, OR) expanded the Honored Citizens Program (HCP) in July 2018 to include low-income …

Homelessness, Water Access, And Environmental Justice In An Urban Environment, Alicia Gamble

Environmental Science and Management Professional Master's Project Reports

Only in recent years has houselessness been viewed as an environmental justice issue, and little is understood about the environmental injustices of water insecurity among unhoused individuals, especially during the COVID-19 pandemic. In order to understand the environmental injustices (i.e., distributive, procedural, and recognition) of the water insecurity process using the cause-response-effect theoretical model, unhoused participants living near services were interviewed in Portland, Oregon about their lived experiences gaining access to water, the barriers they encounter when trying to access water, and the impacts that result from these barriers. Results revealed that COVID-19 was a barrier to water access and …
