Environmental Science and Management Faculty Publications and Presentations

Since its development in the early 2010s, sociohydrology has deepened our understanding of the long-term coevolution of humans and water by integrating insights from both the natural and social sciences, while also fostering an interdisciplinary community. Its modus operandi to date has been to focus on emergent phenomena, manifesting as unintended consequences, in a variety of contexts. The compound disaster that struck Japan’s Noto Peninsula in 2024, and similar experiences in other parts of the world, underscore the urgent need for systemic approaches that are co-developed by academia and practitioners and focus on context-specific solutions. This perspective piece thus calls …

Exploring The Composition Of Forest Collaboratives In Northeastern Oregon, Lee K. Cervany, Rebecca J. Mclain, Kristen Wright

National Policy Consensus Center Publications

Community-based collaboration has been touted as an effective model for forest governance because it promotes democratized decision-making and stakeholder engagement to address landscape-scale problems. Forest collaboratives are assumed to be heterogeneous, consisting of stakeholders with a diverse range of interests. Few studies have systematically explored variables associated with collaborative composition. We identify six elements of collaborative composition for investigation: size, stakeholder diversity, balance, locality–diversity, core attendance, and cross-participation. This exploratory study examines five forest collaborative groups in eastern Oregon (USA). We analyzed meeting minutes over an 18-month period to track attendance and evaluate who shows up and at what frequency. …

Illuminating Two Secondary Schoolteachers’ Praxes On A ‘Terrain Of Freedom:’ Lessons For Teacher Education, Paul Tarc, Nicholas Ng-A-Fook, Tasha Ausman, Catherine James

Northwest Journal of Teacher Education

This paper attunes to the stated focus of this special issue—teacher subjectivities on a terrain of freedom—to consider the qualities, possibilities and limits of teachers’ praxes and development upon this ‘terrain.’ In response to the call, we explore three critical questions: 1) Where does the teacher’s freedom lie amidst required protocols and standardization?; 2) Can teachers transcend how they have been conceived and conditioned?; and 3) How can teachers engage in transformative development? Through a "poetics of teaching," inspired by Hansen (2004), we frame teaching as a curricular and pedagogical art form that melds interdisciplinary, intellectual, aesthetic, and …

Murray, Hyejin Park, Elizabeth Burklow, Arpita Bose, Hana Kim, Kathryn Greenslade, Amy E. Ramage, Collean Combs, Anusha Balasubramanian, Marianne Casilio

Speech and Hearing Sciences Faculty Publications and Presentations

Spoken discourse is integral to everyday communication; improving discourse outcomes is a primary goal for individuals with aphasia and their families. Consequently, the application of discourse analysis in aphasia assessment and treatment has gained increasing attention in both research and clinical settings. Despite its recognized value among researchers and clinicians, several barriers-such as limited time, inadequate training, and lack of resources-continue to impede the widespread use of discourse analysis into clinical practice. To facilitate its broader adoption, speech-language pathologists require access to comprehensive resources that include information on discourse tasks, outcome measures, psychometric properties, and practical examples of how to …

Kolmogorov–Smirnov-Based Edge Centrality Measure For Metric Graphs, Christina Durón, H. Kravitz, Moysey Brio

Mathematics and Statistics Faculty Publications and Presentations

In this work, we introduce an edge centrality measure for the Helmholtz equation on metric graphs, a particular flow network, based on spectral edge energy density. This measure identifies influential edges whose removal significantly changes the energy flow on the network, as indicated by statistically significant p-values from the two-sample Kolmogorov–Smirnov test comparing edge energy densities in the original network to those with a single edge removed. We compare the proposed measure with eight vertex centrality measures applied to a line graph representation of each metric graph, as well as with two edge centrality measures applied directly to each …

Hegemonic Entrepreneurial Masculinities In Patriarchal Contexts: Exploring Men's Entrepreneurship In War-Torn Territories, Doaa Althalathini, Theodore A. Khoury, Nick Rumens

Business Faculty Publications and Presentations

This article examines how the war-torn context in Iraq has affected men’s entrepreneurship and entrepreneurial masculinities. Drawing on the entrepreneurship masculinities literature, Connell’s notion of hegemonic masculinity and in-depth interviews with 21 Iraqi men entrepreneurs, this article demonstrates the complex interplay between entrepreneurship, masculinity and patriarchal dynamics in the context of wars and economic instability in Iraq. Study findings show how Iraqi men often turn to entrepreneurship out of necessity to meet patriarchal expectations of them as primary providers for their families. We contribute to the literature on entrepreneurship, men and masculinities by demonstrating how entrepreneurship not only serves as …

Strengthening Connections: A Randomized Controlled Trial Examining The Impact Of A Supervisor Support Intervention On Loneliness And Military Couple Relationships, Cynthia D. Mohr, Annamarie S. O'Neill, Jacquelyn M. Brady, Todd E. Bodner, Tori L. Crain, Leslie B. Hammer

Psychology Faculty Publications and Presentations

Social connection has been declining across the general population (i.e., the “loneliness epidemic”), though some groups, including military personnel, are experiencing particularly high rates. This has led to calls for a multilevel national strategy, including workplaces, to build social connection (U.S. Surgeon General, 2023). To answer this call, the present study draws on the wise intervention approach (Walton, 2014), multidimensional model of social connection (Holt-Lunstad, 2022), and models of the bidirectional relationship between sleep health and relationship functioning (Gordon et al., 2017; Troxel et al., 2007), to deliver a workplace intervention that builds social connection for military employees and their …

Brice, Jensine Paoletti-Hatcher, E Lydia Wu-Chung, Vincent D. Lai, Daniel L. Argueta, Michelle A. Chen, Itee Mahant, Bryan T. Denny, Charles Green, Luis D. Medina, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Dementia spousal caregivers are at a disproportionate risk for adverse mental and physical health outcomes. Loneliness is associated with depressive symptoms and proinflammatory cytokine production among caregivers. Additionally, childhood trauma, anticipatory grief, and poor sleep quality are all associated with enhanced stress reactivity. This study used a cross-sectional design to investigate whether loneliness is associated with proinflammatory cytokine production and depressive symptoms in caregivers, and whether these relationships are strongest among caregivers who report high levels of childhood trauma, high amounts of anticipatory grief, or poor sleep quality. A sample of 111 dementia spousal caregivers provided blood samples and completed …

The Role Of Neuroscience In Mental Health Management Within The Adhd Population, Kadi Rae Smith

University Honors Theses

Neuroscience-based educational interventions play a role in the management of Attention Deficit Hyperactive Disorder (ADHD), including the regulation of ADHD-correlated depression and anxiety. Existing research shows that elevated rates of depression correspond to anxiety within the ADHD community; approximately 8.83% of the global population. Social ostracization and isolation are established contributors to depression and anxiety which are commonly comorbid with ADHD. The need exists for further investigation of the beneficial impact that an accurate, biological understanding of how the brain works has on the mental health of the ADHD population, and by extension their families, education systems, and medical industries. …

Beyond The Genome: The Racialized Exposome, Flourishing, And Stress Biology In African Americans, A Non-Exhaustive Review, Enye Washington

University Honors Theses

Racial health disparities remain an enduring challenge in the United States, disproportionately impacting African American communities through higher rates of chronic disease and premature mortality. This non-exhaustive literature explores how the racialized exposome - a term denoting the totality of social, environmental, and structural stressors rooted in systemic racism - biologically embeds itself via stress-responsive pathways. Specifically, it examines the interaction between racial stress, flourishing, and key biological markers, including allostatic load and telomere length, considering the gut-brain axis. The review highlights robust evidence that chronic exposure to racial discrimination and structural adversity contributes to multisystem dysregulation and accelerated cellular …

The Discovery, Communication, And Implementation Of New Geologic Findings: Examining The Cascadia Earthquake, Saylor Brainard

University Honors Theses

The Cascadia Subduction Zone, located off the Coast of the Pacific Northwest, is at risk of generating a 9.0 magnitude earthquake in the near future. Despite its significance, the discovery of the seismic potential of Cascadia didn't occur until 1987, when geologist Brian Atwater searched for non-traditional forms of earthquake evidence. As decades of continued research fleshed out Atwater's initial discovery, the implications associated with the discovery became apparent, presenting Washington and Oregon with the high probability that a massive earthquake will take place within the next century. Communicating the severity of this geologic discovery to both the public and …

The Correlation Of Trauma-Informed Classrooms Without Support Infrastructure And Teacher Burnout, Sunshine O'Connor

University Honors Theses

This thesis examines the impact of Trauma-Informed Care (TIC) implementation in classrooms on teacher burnout, specifically focusing on settings with insufficient support infrastructure. While TIC is recognized as beneficial for all students, not just students affected by trauma, a synthesis of scholarly literature highlights the significant challenges faced by educators when proper resources, training, and institutional backing are lacking. Existing research indicates that teachers implementing TIC in inadequately supported environments report higher levels of emotional exhaustion, depersonalization, and overall burnout. These challenges appear most acute for teachers in schools with limited professional development, insufficient mental health resources, and weak administrative …

Beyond Capitalist Realism: Indigenous Worldviews As Critique And Alternative, Celine Jessup

University Honors Theses

This paper engages Mark Fisher's Capitalist Realism: Is There No Alternative? as a foundational critique of late capitalism's ideological dominance, and proposes Indigenous worldviews as both a critical lens and a generative alternative. Fisher defines capitalist realism as a pervasive structure that colonizes imagination, depoliticizes systemic crises, and renders other ways of living unthinkable. He illustrates how capitalism commodifies resistance, pathologizes dissent, and obscures accountability, particularly through institutions like the call center and discourses on mental health and climate change. In contrast, the paper turns to Indigenous political theories—drawing on thinkers such as Kim TallBear, Daniel Heath Justice, Ocean Ripeka …

Changing Minds, Changing Modes: Optimizing Public Perception Strategies For Urban Cycling Through Behavior Change Theory, Brandon Barnhart

University Honors Theses

This thesis addresses the recent decline in bicycle mode share in cities like Portland, Oregon, despite decades of investment in cycling infrastructure. While the "build it, and they will come" approach succeeded through the early 2000s, it no longer meets targets for bicycle use or broader goals related to sustainability, congestion, health, and safety. A new approach is needed that effectively rebuilds the cultural and behavioral components of cycling. This research asks: What role can behavior change theory play in increasing the effectiveness of public perception campaigns to promote urban cycling? Using a qualitative methodology, this study draws on behavior …

Investigating Hedgehog Signaling And Th17-Mediated Inflammation In Blau Syndrome: Insights Into Chronic Inflammation, Benjamin Volinski

University Honors Theses

Blau syndrome is a rare, monogenic inflammatory disorder caused by autosomal dominant mutations in NOD2, a cytosolic pattern recognition receptor that regulates immune signaling. Although traditionally considered an autoinflammatory disease driven by innate immune dysfunction, emerging evidence implicates T cells in Blau pathogenesis. Recent studies show that Nod2-deficient mice exhibit elevated IL-17A production despite normal TH17 differentiation, suggesting Nod2 regulates cytokine output independently of canonical lineage commitment. This study investigates how Nod2 mutations influence TH17-mediated inflammation and explores the role of Hedgehog (Hh) signaling, particularly the transcription factor Gli2, in this process.

Using the Nod2^R314Q/R314Q mouse model, …
