Novel Viruses Of The Family Partitiviridae Discovered In Saccharomyces Cerevisiae, Angela M. Crabtree, Ignacio De La Higuera, Kenneth Stedman, Multiple Additional Authors

Biology Faculty Publications and Presentations

It has been 49 years since the last discovery of a new virus family in the model yeast Saccharomyces cerevisiae. A large-scale screen to determine the diversity of double-stranded RNA (dsRNA) viruses in S. cerevisiae has identified multiple novel viruses from the family Partitiviridae that have been previously shown to infect plants, fungi, protozoans, and insects. Most S. cerevisiae partitiviruses (ScPVs) are associated with strains of yeasts isolated from coffee and cacao beans. The presence of partitiviruses was confirmed by sequencing the viral dsRNAs and purifying and visualizing isometric, non-enveloped viral particles. ScPVs have a typical bipartite …

Biology Faculty Publications and Presentations

Lizards are the most diversified group of living reptiles with 7176 species worldwide (Uetz 2022). They play key roles in ecosystems where they are prey to a wide variety of predators, including snakes, other lizards, mammals, birds, and invertebrates (Pianka and Vitt 2006). The tropical forests of the new world contain a high variety of species of different sizes, shapes, and colors. In Costa Rica in particular, at least 80 species of lizards have been reported (Leenders 2019). They occupy highly diverse habitat types where they participate in food webs that involve many other species of vertebrates and invertebrates.

The Role Of High-Order Anharmonicity And Off-Diagonal Terms In Thermal Conductivity: A Case Study Of Multi-Phase Cspbbr3, Xiangdong Ding, Guimei Zhu, Yi Xia, Jie Ren, Jun Sun, Multiple Additional Authors

Mechanical and Materials Engineering Faculty Publications and Presentations

We investigate the influence of three- and four-phonon scattering, perturbative anharmonic phonon renormalization, and off-diagonal terms of coherent phonons on the thermal conductivity of CsPbBr3 phase change perovskite, by using advanced implementations and first-principles simulations. Our study spans a wide temperature range covering the entire structural spectrum. Notably, we demonstrate that the interactions between acoustic and optical phonons result in contrasting trends of phonon frequency shifts for the high-lying optical phonons in orthorhombic and cubic CsPbBr3 as temperature varies. Our findings highlight the significance of wavelike tunneling of coherent phonons in ultralow and glasslike thermal conductivity in halide perovskites.

Earthbound In The Anthropocene: Spirituality, Collective Identity, And Participation In The Direct Action Climate Movement, David Alan Osborn

Dissertations and Theses

Climate change, as part of a broader ecological crisis, is becoming an ever more potent event structuring human societies and planetary ecosystems. As the climate crisis deepens, climate change is unsettling core human identities, as well as the ontologies that define and situate concepts of "human" and "nature." And as social movements act to challenge and mitigate the catastrophes arising in the Anthropocene era, the question of how to sustain participation is critical. This dissertation explores these dynamics through a study of spirituality, collective identity, participation, and ontology in a subset of the climate movement. The research questions were: (1a) …

A Literature Review On Understanding, Solidifying, And Expanding The Role Of Art Therapy In Death And Dying, Deborah D. Clark

University Honors Theses

The purpose of this literature review is to weave together an understanding of what research exists around art therapy in death and dying, what the role of art therapy is in end-of-life care and education, and determine what gaps exist for further study. When it comes to the topic of death and dying, most of us would agree that end-of-life care is extremely important, though this agreement often falls apart regarding what that care looks like, and how we do (or don't) talk and learn about death and dying. This review argues for an integrated holistic model of care concerning …

Sartorial Representations Of Trans Men In The Post-Frontier West: A Case Study In Gender, Class, And Concepts Of Societal Degeneration, Rose Caughie

University Honors Theses

Clothing is communication. How it is perceived reveals a society's values and anxieties. In the post-frontier American west, moralistic laws against cross-dressing combined with fears of societal degeneration, resulting in the formation and enforcement of normative visions of gendered dress. When trans men Harry Allen and Milton Matson were arrested, images of them were published in newspapers across the nation. Allen's working class wear and close criminal contact with racial minorities reflects one perceived source of degeneration while Matson's high class look and British immigrant status reflects the other. This essay will consider how these men's clothing and bodies were …

Riparian and wetland willow species have undergone serious declines in Rocky Mountain National Park as a consequence of a variety of environmental changes and, most recently, damage resulting from moose overpopulation. To address concerns about the long-term status of willows in the park, we developed remote sensing-based raster maps of riparian and wetland willow species presence, canopy cover percentage, canopy height, and leaf area index. All outputs were produced at 3-meter resolution, and represent willows as they existed in 2021. The mapping was performed via random forests classification and regression models trained on several hundred vegetation plots from a variety …

Local Voices: Counterstorytelling And Retention Of Faculty Of Color In Oregon's Community College System, Kristin Christophersen

Dissertations and Theses

The Oregon community college system employs a full-time faculty workforce that is overwhelmingly White. This study aimed to research why the representation of faculty of color in the state’s community colleges remains low by conducting interviews with faculty of color about their experiences at these public 2-year institutions using counterstorytelling as research methodology. Using critical race theory as a theoretical framework, this study collected and analyzed the counterstories of seven faculty of color in a variety of institutions and regions across one state about their experiences with institutional racism and how it impacts their persistence strategies and retention patterns.

Experiences Of People With Serious Mental Illness Seeking Services At Community Mental Health Centers During The Covid-19 Pandemic, Emily Leickly

Dissertations and Theses

Community mental health centers (CMHCs) have been underfunded and overburdened since Reagan-era disinvestment and the United States' move toward neoliberalism. Rates of mental illness have been rising consistently, particularly in Oregon, as CMHCs face continuing financial pressures and staff retention issues. This was before the COVID-19 pandemic. Today, we are still trying to understand the ongoing pandemic's impact on people with serious mental illnesses (SMI). Most of the studies in this area thus far are quantitative, and first-hand accounts of the pandemic from people with SMI are largely absent. Additionally, research in this area fails to draw on critical alternative …

Phytoplankton Community As An Indicator Of Cyanobacteria Harmful Algal Blooms In High Mountain Lakes, Victoria Elizabeth Avalos

Dissertations and Theses

Cyanobacteria blooms are a growing issue worldwide and can be harmful to both aquatic life and human health. Warm temperatures, nutrient loading, stable water columns, and selective grazing of zooplankton and phytoplankton can contribute to cyanobacteria bloom formation. In this study, I characterized the algal communities and water quality differences in two physiographically similar lakes with relatively little human influences, Odell and Crescent Lakes, Oregon, to better understand potential contributing factors to cyanobacteria harmful algal bloom formation (cyanobacteria bloom) in Odell Lake.

There are three hypotheses in this study:

1. If there was a cyanobacteria bloom in Odell Lake, but not …

Explore Regional Variation In The Effects Of Built Environment On Driving With High Resolution U.S. Nationwide Data, Liming Wang

PSU Transportation Seminars

There have been numerous studies on the relationship between travel behavior and built environment over the last few decades. Prior studies have mostly focused on producing point estimates of model coefficients and ended up with a wide range of estimates for the built environment elasticity of travel behavior, including household Vehicle Miles Traveled. With few exceptions, previous studies use data from a single region or a small number of regions, and thus are not able to sufficiently investigate the regional variation in built environment elasticity.

On the other hand, a few papers have addressed the heterogeneity of elasticity among different …

"I'M Clean And Sober, But Not Necessarily Free": Perceptions Of Buprenorphine Among Patients In Long-Term Treatment, Jessica J. Wyse, Travis I. Lovejoy, Adam J. Gordon, Katherine Mackey, Anders Herreid-O'Neill, Benjamin J. Morasco

OHSU-PSU School of Public Health Faculty Publications and Presentations

Patients receiving buprenorphine for the treatment of opioid use disorder (OUD) experience a roughly 50% reduction in mortality risk relative to those not receiving medication. Longer periods of treatment are also associated with improved clinical outcomes. Despite this, patients often express desires to discontinue treatment and some view taper as treatment success. Little is known about the beliefs and medication perspectives of patients engaged in long-term buprenorphine treatment that may underlie motivations to discontinue.
