Delaware’S Climate Action Plan: Omission Of Source Attribution From Land Conversion Emissions, Elena A. Mikhailova, Lili Lin, Hamdi A. Zurqani, Zhenbang Hao, Christopher J. Post, Mark A. Schlautman, Gregory C. Post, George B. Shepard

Geography Faculty Publications and Presentations

Delaware’s (DE) Climate Action Plan lays out a pathway to reduce greenhouse gas (GHG) emissions by at least 26% by 2025 but does not consider soil-based GHG emissions from land conversions. Consequently, DE’s climate action plan fails to account for the contribution of emissions from ongoing land development economic activity to climate change. Source attribution (SA) is a special field within the science of climate change attribution, which can generate “documentary evidence” (e.g., GHG emissions inventory, etc.). The combination of remote sensing and soil information data analysis can identify the source attribution of GHG emissions from land conversions for DE. …

Disentangling The Nazis And The Vikings, Arden Goldberg

Student Research Symposium

In the development of nationalism, and specifically white ethnonationalism, the Norse have played an unfortunate role, and one that deserves a closer interrogation. In the larger scheme of white nationalism, those who seek to directly appropriate Norse symbology and a reconstruction of their own ideal of Norse culture are a relative minority, but they remain a minority which taints the study of Norse history. In this talk, I will examine how Norse symbology and identity has come to be appropriated by white nationalists, compare the racist perceptions of the Norse with knowable historical realities, explain the usefulness of Norse symbology …

Farmworker Voices: Contesting & Renegotiating Essential Status During The Covid-19 Pandemic, Jennifer Martinez

Student Research Symposium

This study draws on a subset of thirty individuals that took part in the community-driven Oregon COVID-19 Farmworker Study to analyze how farmworkers interpreted the contradictory label essential worker. Using discourse analysis, this article examines how these peasant workers drew on their embodied experiences working throughout the pandemic to give meaning to their essential designation. The data suggest that farmworkers were tacitly aware of the contradictions between their labeling as indispensable and their disposable treatment on the ground. Farmworkers generally felt unrecognized, underpaid, and felt exposed to COVID-19 infection in addition to everyday workplace hazards. While the essential title was …

Research Proposal For An Assessment Of The Potential For The Arbuscular Fungi “Rhizophagus Irregularis” To Aid In Corn Uptake And Availability Of Iron, Caitlin Costello

Student Research Symposium

Global iron deficiency is one factor contributing to malnutrition and varied health conditions. This deficiency accounts for 841,000 deaths and approximately 35,057,000 “disability-adjusted life years lost” (Stoltzfus, R. J. 2003). One way to combat this is to maintain or increase the iron uptake of the globe’s major crops. Research has shown that certain types of mycorrhizal fungi can increase the nutrient uptake of plants. To further this research, we will look at the arbuscular fungi Rhizophagus irregularis and its potential relationship with a short harvest corn variety. This type of mycorrhizal fungi improves plant nutrition including the plant’s ability to …

Daily Work, Nonwork, And Stress Experiences Of Students, Erika A. Schemmel, Tori L. Crain, Rachel G. Lucas-Thompson

Student Research Symposium

A substantial body of literature exists that examines work, nonwork, and stress in employed adults. Less is known about experiences of stress in adolescents and emerging adults. The goal of the present study is to examine the association between daily activities and next day stress within a sample of students. We propose that students use their personal resources to meet school demands, and then need to replenish those resources, or stress may ensure. One aim of this study is to examine the relationship of hours of exercise and sleep with students’ reports of stress the next day. Additionally, many students …

Case Study In Activist Applied Linguistics: Working With The Oregon Judicial Department For The Accessibility Of Domestic Relations Information, Amandalyn R. Wayland, Jamal R. Ford, Abbee A. Mortensen

Student Research Symposium

How are students of applied linguistics able to contribute to community efforts in increasing access to justice? Activist applied linguistics (AAL) (Cowal & Leung, 2021) is defined as utilizing applied linguistics in coordination with community partners to address wicked problems (Rittel & Webber, 1973). AAL provides a framework for engaging university students with communities outside of their campus and has been utilized to further work in water justice (Haeffner & Cowal, 2019) and to increase the Oregon State Bar website’s comprehensibility (Anesa, Cowal, & Pulju, 2022). In this poster, we present an AAL case study in which students of applied …

Simple Arenes As Aryne Synthetic Equivalents Via Sulfonium Salt Intermediates, Riley A. Roberts

Student Research Symposium

Arynes are ephemeral molecules that are yet to be fully exploited in synthetic strategy because they are often challenging to access. These reactive intermediates participate in a myriad of reactions that conventional chemistry is incapable of, making them extremely useful for the synthesis of important molecules like pharmaceuticals and agrochemicals. While classical approaches for synthesizing arynes employ cheap starting material, extremely harsh reagents are necessary to generate the aryne. In contrast, methods that do not require harsh reaction conditions do require starting material that is exceedingly difficult to synthesize. To access arynes quickly and efficiently, the work described herein aims …

Mental Health In Student Leadership: Perceptions Of Ability, Rose M. Jardine

Student Research Symposium

This proposal aims to evaluate the relationship between perceptions of mental health and leadership ability among student leaders in university communities.

Over fifty participants, including faculty and students, from Oregon universities and community colleges are expected to contribute to this study. Participants will answer a survey and be randomly assigned to one of four situations describing a student leader’s disclosure or non-disclosure, both with and without Bipolar 1 Disorder. Bipolar 1 Disorder was chosen for this study based on its intermittence, varying severity, higher associated stigma, and symptomatology that can include externally perceived increased productivity. They will respond to this …

Understanding Work And Sleep Through A Machine Learning Approach, Jennifer Saucedo, Josh J. Prasad, Tori L. Crain

Student Research Symposium

The present study will utilize machine learning methods to find the individual factors (e.g, demographic, lifestyle, contextual, work-related) best predict sleep. I will examine (1) whether machine learning techniques better predict sleep over linear prediction methods and (2) what factors are most important when predicting sleep. Using government-funded data from the Bureau of Labor Statistics (BLS), a variety of prediction methods will be utilized to evaluate and compare predictive performance across 2018, 2019, and 2020. Results found will have a variety of theoretical and practical implications for scientists and practitioners.

The Effects Of Approach And Avoidance Dispositions And Sense Of Power On Promotive And Prohibitive Voice Efficacy, Christopher J. Waterbury, Avery N. Waklatsi, Amy Pytlovany Ph.D.

Student Research Symposium

Developments in research on promotive and prohibitive voice in workplaces have important implications for organizational innovation and prevention of unethical behavior. Drawing on theory that approach and avoidance dispositions predict promotive and prohibitive voice, and mediate the effect of a sense of powerfulness or powerlessness to predict voice or silence, the proposed study hypothesizes that approach and avoidance disposition will explain differential effects of personal sense of power on an employee’s perceived efficacy of promotive and prohibitive voice. 200 front-line restaurant workers will be recruited and randomly assigned to receive a (1) powerful prime, (2) powerless prime, or (3) control …

Reduce, Reuse And Deny: How Sustainability Is Judged By Consumers, Madison E. Hill

Student Research Symposium

This research was an analysis of a series of interviews regarding what factors are considered when deciding if a given product is environmentally friendly or not. Participants were asked to select between products or practices as the generally more sustainable option, and were asked to explain their reasoning for that decision. Participants were encouraged to describe their reasoning behind each choice, but it was noted when certain choices were more challenging than others. Products that green-wash effectively generate trust between consumers trying to ‘do their part’ and industries attempting to capitalize on each side of environmental crises. Most sustainable practices …

Climate Model Skill At Simulating Large-Scale Atmospheric Circulation Patterns And Associated Temperature And Precipitation Over The Pacific Northwest, Graham Taylor

Student Research Symposium

The ability of the latest state-of-the-art suite of climate models to simulate observed large-scale atmospheric circulation patterns over the Pacific Northwest of North America is evaluated. Twelve representative patterns of atmospheric circulation are identified using machine learning applied to observational data. Climate model data from simulations of the historical period are mapped to each observational-derived pattern, and the resulting differences between patterns, as well as differences in frequency of pattern occurrence, are quantified. In general, models are able to simulate the range of circulation patterns with reasonable accuracy, although model skill varies to some degree across the 25-member climate model …

Computational Investigation Of The Mechanism Of An Octahedral Ni(Ii) Proton Reduction Catalyst And Importance Of Intramolecular Hydrogen Bonding, Avik Bhattacharjee, Dayalis S.V. Brown, Carolyn N. Virca, Trent E. Ethridge, Oreana Mendez Galue, Uyen T. Pham, Theresa M. Mccormick

Student Research Symposium

Water-splitting to make hydrogen gas is of extreme importance in the field of alternative energy research. Transition-metal complexes are capable of catalyzing the conversion of water to hydrogen at higher pH, with low overpotential. Our research focuses on the importance of intramolecular hydrogen bonding (H-bonding) on the pKa and thermodynamic stability of the catalytic intermediates of a well-known proton-reduction catalyst, nickel (II) tris-pyridinethiolate. Density Functional Theory (DFT) calculations on the parent catalyst and eleven derivatives demonstrate geometric isomer formation after the protonation step of catalysis. These isomers differ in the relative thermodynamic stabilities and pKa values, which can be attributed …

Evaluation Of Oregon’S Food Waste Recovery And Reintegration Policy Adoption Through Civic Capacity, Jenna N. Stathopoulos

Student Research Symposium

The US Food System is complex and multi-layered, containing many areas for improvement. My research focuses specifically on the issue area of food waste. On a global and national scale mitigating food waste can seem too large to manage. Containing complexity across multiple sectors and with extended timelines for improvements, it is indeed a wicked problem, a problem which in its complexity is almost impossible to fully distinguish or address with one (or even multiple) solutions. (Rittel, 1973). However, when we look to local, place-based solutions we can develop more realistic and actionable plans. The state of Oregon is equipped …

Analysis Of Aftershock Parameters For The Alaskan Subduction Zone Tectonic Region, Gabrielle M. Paris (They/Them), Richard C. Hugo, Andrew J. Michael

Student Research Symposium

On 29 July 2021, a magnitude 8.2 earthquake was felt by over 200 people near Perryville, Alaska. The early aftershock forecasts issued by the USGS use default parameters based on expected productivity within a given tectonic region. These forecasts predicted a slower decrease in aftershock activity than what was observed. Even after the USGS adjusted the aftershock forecast parameters, the forecasts did not improve in the long term. Accurate aftershock predictions are important for maintaining public confidence in disaster alert systems. The question I want to explore is: are the generic parameters used in aftershock forecasting accurately describing the observed …

Discussion Of “Guiding Principles For Hydrologists Conducting Interdisciplinary Research And Fieldwork With Participants”, Melissa Haeffner

Environmental Science and Management Faculty Publications and Presentations

Rangecroft et al. (2021) offer a set of principles for conducting interdisciplinary research and fieldwork with participants from a hydrologist perspective. In this invited paper, I present some thoughts from a social scientist’s perspective, not to disagree with their points but to add to them. Specifically, I use my sociology background and interdisciplinary experiences to reflect on qualitative evaluative criteria, power dynamics in the scientific community, barriers to interdisciplinary research, and approaches to overcome obstacles. Individual researchers can educate themselves about other disciplines, and there are also opportunities for institutional change on the part of universities, funders, and …

Poetry To Prose: The Influence Of Herodotus On Written History, Frances B. Currie

Young Historians Conference

In his book, The Histories, Herodotus of Halicarnassus expertly displayed his inquiries into the cultures and conflicts that transformed the Mediterranean world during the Greco-Persian Wars of the fifth century BCE. By writing his narrative in prose, citing his work, and providing cultural reasoning for past events, Herodotus earned himself the nicknames “father of history” and “father of comparative ethnography,” but his inclusion of fables also labeled him the “father of lies.” A historian named Thucydides eventually refined the historical genre to focus on politics without the inclusion of myths, narrowing the discipline of history for another thousand years. …

Spatial And Temporal Variations Of Microplastic Concentrations In Portland's Freshwater Ecosystems, Rebecca Talbot, Elise F. Granek, Heejun Chang, Rosemary Wood, Susanne Brander

Geography Faculty Publications and Presentations

While microplastics are a pollutant of growing concern in various environmental compartments, less is known regarding the sources and delivery pathways of microplastics in urban rivers. We investigated the relationship between microplastic concentrations and various spatiotemporal factors (e.g., land use, arterial road length, water velocity, precipitation) in two watersheds along an urban-rural gradient in the Portland metropolitan area. Samples were collected in August, September, and February and were analyzed for total microplastic count and type. Nonparametric statistics were used to evaluate potential relationships with the explanatory variables, derived at both the subwatershed and near stream scales. In August, microplastic concentrations …

Extreme Winds Alter Influence Of Fuels And Topography On Megafire Burn Severity In Seasonal Temperate Rainforests Under Record Fuel Aridity, Cody Evers, Andres Holz, Sebastian Upton Busby, Max Nielsen-Pincus

Environmental Science and Management Faculty Publications and Presentations

Nearly 0.8 million hectares of land were burned in the North American Pacific Northwest (PNW) over two weeks under record-breaking fuel aridity and winds during the extraordinary 2020 fire season, representing a rare example of megafires in forests west of the Cascade Mountains. We quantified the relative influence of weather, vegetation, and topography on patterns of high burn severity (>75% tree mortality) among five synchronous megafires in the western Cascade Mountains. Despite the conventional wisdom in climate-limited fire regimes that regional drivers (e.g., extreme aridity, and synoptic winds) overwhelm local controls on vegetation mortality patterns (e.g., vegetation structure and …

Temporary Housing Alternatives: Economic Analysis, Matt Gillispie, Swapna Kandula, Girija Patil, Juan Vasconez, Jennifer Lynn Zeitouni

Engineering and Technology Management Student Projects

In this report, we are aiming to find the best construction alternative to provide housing to the homeless community of Multnomah County in Oregon. The goal is to identify the most beneficial construction process through an economic analysis. In conjunction with existing projects such as “Safe Rest Villages” that are working on offering services and solutions, the plan is to reduce the county’s houseless population by 50% over a time period of 10 years. The analysis includes gathering data about the community, but also calculating the costs and benefits of three alternatives - 3D Printed houses, tiny homes, and prefabricated …

Urban Flood Risk And Green Infrastructure: Who Is Exposed To Risk And Who Benefits From Investment? A Case Study Of Three U.S. Cities, Arun K. Pallathadka, Jason Sauer, Heejun Chang, Nancy B. Grimm

Geography Faculty Publications and Presentations

Pluvial flooding is a serious hazard in inland U.S. cities. City managers and communities are increasingly interested in reducing their pluvial flood risk through the development of green infrastructure (GI) features. This research explores the relationship between pluvial flood exposure and GI placement in three inland cities– Atlanta, Phoenix, and Portland–and analyzes the variation of sociodemographic variables in census block groups (CBG) located in pluvial flood zones. Using the Arc-Malstrøm method, we estimated areas of pluvial flooding in the CBGs of our selected cities by relating pluvial flood area to the density of GI in CBGs and assigning CBGs one …

Tradeoffs And Synergies Across Global Climate Change Adaptations In The Food‐Energy‐Water Nexus, Sarah Torhan, Caitlin A. Grady, Idowu Ajibade, Eranga K. Galappaththi, Rebecca R. Hernandez, Justice I. Musah‐Surugu, A. M. Nunbogu, A. C. Segnon, Multiple Additional Authors

Geography Faculty Publications and Presentations

Food-energy-water (FEW) systems are increasingly vulnerable to natural hazards and climate change risks, yet humans depend on these systems for their daily needs, wellbeing, and survival. We investigated how adaptations related to FEW vulnerabilities are occurring and what the global community can learn about the interactions across these adaptations. We conducted a global analysis of a data set derived from scientific literature to present the first large scale assessment (n = 1,204) of evidence-based FEW-related climate adaptations. We found that the most frequently reported adaptations to FEW vulnerabilities by continent occurred in Africa (n = 495) and Asia (n = …

Unhoused And Unhireable? Examining Employment Biases In Service Contexts Related To Perceived Warmth And Competence Of People Experiencing Houselessness, Larry R. Martinez, Nicholas A. Smith, Megan J. Snoeyink, Breffni M. Noone, Alex Shockley

Psychology Faculty Publications and Presentations

Lack of safe and stable housing is a pernicious and growing social concern, and stereotypes about individuals experiencing houselessness are generally quite negative. Little scholarly work has examined housing insecurity and its associated stereotypes in employment contexts. The purpose of the current research was to examine, in the context of the hospitality industry, whether housing status influences hiring managers' perceptions of hireability (Study 1) and customers' evaluations of an organization and its employees (Study 2) using the stereotype content model. Across two experimental studies, we assessed participant attitudes toward individuals experiencing houselessness. In Study 1, we instructed 148 hotel managers …

Illustrating Ensemble Predictability Across Scales Associated With The 13–15 February 2019 Atmospheric River Event, Chad W. Hecht, Allison C. Michaelis, Andrew C. Martin, Jason M. Cordeira, Forest Cannon, F. Martin Ralph

Geography Faculty Publications and Presentations

The “Valentine’s Day” atmospheric river (AR) event that affected a majority of California during 13–15 February 2019 ranked as an AR3 (Ralph et al. 2019) along most of the California coast and reached AR4 intensity in Southern California. The strong onshore flow and dynamically favorable characteristics of the Valentine’s Day AR produced both an intense and long-duration precipitation event resulting in widespread hydrometeorological impacts across California. Palomar Observatory in northern San Diego County observed >10 in. (>254 mm) of precipitation in 24 h, the highest 24-h accumulation since record keeping began in 1943 (Hatchet et al. 2020
