Sensitivity Analysis Of An Agent-Based Simulation Model Using Reconstructability Analysis, Andey M. Nunes, Martin Zwick, Wayne Wakeland

Systems Science Faculty Publications and Presentations

Reconstructability analysis, a methodology based on information theory and graph theory, was used to perform a sensitivity analysis of an agent-based model. The NetLogo BehaviorSpace tool was employed to do a full 2^k factorial parameter sweep on Uri Wilensky’s Wealth Distribution NetLogo model, to which a Gini-coefficient convergence condition was added. The analysis identified the most influential predictors (parameters and their interactions) of the Gini coefficient wealth inequality outcome. Implications of this type of analysis for building and testing agent-based simulation models are discussed.

Anatomy Of A Violent Protest Wave: Understanding The Mechanisms Of Escalation And De-Escalation In Far-Right And Anti-Fascist Street Clashes, Leanne Claire Serbulo

University Studies Faculty Publications and Presentations

With the rise of right-wing populist ideologies and ensuing social polarization, political violence has become more widespread. Between 2017 and 2019, far-right extremists and anti-fascists engaged in more than twenty violent protest clashes in Portland, Oregon, USA. Through a protest event analysis of those clashes supplemented with a case study of the protest wave, this paper explores how the mechanisms of radicalization and de-radicalization operate when two violent protest movements collide and interact with state security forces. The three-way interaction among a movement, counter-movement, and the police can produce unanticipated outcomes. For example, rather than de-escalating the situation, police underbidding …

To What Extent Do Local Nursing Home Prescribing Patterns Relate To Psychotropic Prescribing In Assisted Living?, Kali Thomas, Christopher J. Wretman, Philip D. Sloane, Paula Carder, Lindsay Schwartz, Anna S. Beeber, Sheryl Zimmerman

Institute on Aging Publications

In nursing homes (NHs), psychoactive medication use has received notable attention, but less is known about prescribing in assisted living (AL). This study examined how antipsychotic and antianxiety medication prescribing in AL compares with NHs.

Environmental And Spatial Factors Affecting Surface Water Quality In A Himalayan Watershed, Central Nepal, Janardan Mainali, Heejun Chang

Geography Faculty Publications and Presentations

Various spatial interrelationships among sampling stations are not well explored in the spatial modeling of water quality literature. This research explores the relationship between water quality and various social, demographic, and topographic factors in an urbanizing watershed of Nepal with a comparison of different connectivity matrices to conceptualize spatial interrelationships. We collected electrical conductivity and dissolved oxygen data from surface water bodies using a handheld probe and used the data to establish relationships with land use, topography, and population density-based explanatory variables at both watershed and 100-m buffer scales. The linear regression model was compared with different eigenvector-based spatial filtering …

Estimating Posterior Quantity Of Interest Expectations In A Multilevel Scalable Framework, Hillary R. Fairbanks, Sarah Osborn, Panayot S. Vassilevski

Mathematics and Statistics Faculty Publications and Presentations

Scalable approaches for uncertainty quantification are necessary for characterizing prediction confidence in large‐scale subsurface flow simulations with uncertain permeability. To this end we explore a multilevel Monte Carlo approach for estimating posterior moments of a particular quantity of interest, where we employ an element‐agglomerated algebraic multigrid (AMG) technique to generate the hierarchy of coarse spaces with guaranteed approximation properties for both the generation of spatially correlated random fields and the forward simulation of Darcy's law to model subsurface flow. In both these components (sampling and forward solves), we exploit solvers that rely on state‐of‐the‐art scalable AMG. To showcase the applicability …

Control Of Blood Volume Following Hypovolemic Challenge In Vertebrates: Transcapillary Versus Lymphatic Mechanisms., Stanley S. Hillman, Robert C. Drewes, Michael S. Hedrick

Biology Faculty Publications and Presentations

Anurans have an exceptional capacity for maintaining vascular volume compared with other groups of vertebrates. They can mobilize interstitial fluids via lymphatic return at rates that are ten-fold higher than mammals. This extraordinary capacity is the result of coordination of specialized skeletal muscles and pulmonary ventilation that vary volume and pressure of subcutaneous lymph sacs, thus moving lymph to dorsally located lymph hearts that return lymph to the vascular space. Variation in the capacity to mobilize lymph within anurans varies with the degree of terrestriality, development of skeletal muscles, lung volume and lung compliance, and lymph heart pressure development. This …

Adaptive Courseware Implementation: Investigating Alignment, Course Redesign, And The Student Experience, Patricia O'Sullivan, Janelle De Carrico Voegele, Tonya Buchan, Raiza Dottin, Kari Goin Kono, Misty Hamideh, Wendy S. Howard, Jennifer Todd, Stanley Kruse, Johannes De Gruyter, Kevin Berg

This paper highlights the …

The Long-Haul: Buddhist Educational Strategies To Strengthen Students’ Resilience For Lifelong Personal Transformation And Positive Community Change, Namdrol Miranda Adams, Kevin Kecskes

Public Administration Faculty Publications and Presentations

For decades, community engagement scholars have built a robust body of knowledge that explores multiple facets of the higher education community engagement domain. More recently, scholars and practitioners from mainly Christian affiliated faith-based institutions have begun to investigate the complex inner world of community-engaged students’ meaning-making and spiritual development. While most of this fascinating cross-domain effort has been primarily based on “Western” influenced Judeo-Christian traditions, this study explores service-learning/community engagement themes, approaches, rationale, and strategies from an “Eastern” perspective based on the rich tradition of Tibetan Buddhism. This case study research focuses on curricular approaches, influences, and impacts of Buddhist …

Brief Report: The Impact Of Disease Stage On Early Gaps In Art In The "Treatment For All" Era - A Multisite Cohort Study., Ingrid T. Katz, Nicholas Musinguzi, Kathleen Bell, Anna Cross, Mwebesa Bosco Bwana, Gideon Amanyire, Stephen Asiimwe, Catherine Orrell, David R. Bangsberg, Jessica E. Haberer

OHSU-PSU School of Public Health Faculty Publications and Presentations

Adoption of "Treat All" policies has increased ART initiation in sub-Saharan Africa; however, unexplained early losses continue to occur. More information is needed to understand why treatment discontinuation continues at this vulnerable stage in care.

Working Paper No. 46, Foundations For Feminist Legal Theory, Taylor Feltham

Working Papers in Economics

This inquiry seeks to establish the foundations for Feminist Legal Theory through considering its three important dimensions. These dimensions are: a) a distinct and unique historical background; b) an ongoing legacy of occupational segregation; and c) a persistence of gender inequality. This inquiry relies heavily upon Feminist Legal Theory: A Primer (2016) authored by Nancy Levit, et al. Since the emergence of the area of inquiry known as “critical race feminism,” feminist legal theory has been moving away from the principle of formal equality and towards intersectional equity. Feminist legal theorists like Angela Harris (1990), in her work Race and …

Working Paper No. 47, The Transformation Of Developmental States: Patterns Of Economic Development In South Korea And Taiwan, Mina Kim

Working Papers in Economics

This inquiry considers similar yet contrasting patterns in the economic development of South Korea and Taiwan. Taiwan’s developmental state has tended to exhibit ‘softer’ characteristics than South Korea’s. I identify a tendency for when developmental states face crises and then transition forward to a ‘post-developmental state’. This is traced to the internal 'paradox of success' and external pressure of neoliberal globalization. Though these two countries tend to embrace and rely upon neoliberal policies for economic growth, the speed and degree of systemic change register as different. A 1997 financial crisis appears to have goaded South Korea to move quickly through …

Working Paper No. 48, Struggle Over China, Joshua Stanfill

Working Papers in Economics

This inquiry seeks to establish that after Dr. Sun Yat-sen thought through and then laid the foundations for the modern Chinese state, a struggle for power emerged between those identifying as nationalists and communists. Sun’s ideas regarding some of the effects of western imperialism on Asian countries were shared by both the Chinese Communist Party and the Nationalist Party under Chiang Kai-shek. The ideological bases for the struggle between the two parties for China emerged in their beliefs regarding relationships between government and citizens, and the role of the government. Soon after Dr. Sun’s death, a struggle for power over …

“Building That World”: Movements Of Vision In The Carceral Classroom, Rhiannon M. Cates, Benjamin J. Hall, James Broughton, Andrew Reeves, Faith Hocutt Ringwelski, Kathryn Zaro, Jenna Richards, Lani Roberts

Library Faculty and Staff Publications and Presentations

An article in which two teaching assistants and six students of a university course taught inside a correctional facility, "Writing as Activism," collaboratively examine their experience as co-teachers and co-learners in a humanities-based prison classroom. Fostered and framed by their instructor’s critical and transformative pedagogical approaches in this course, the authors locate integrated learning and collaborative writing within carceral classrooms as sites for intentional and resistant futures to be enacted and embodied as a practice of post-carceral world-building. The students enter their individual narratives into this location of their experience of envisioning and enacting resistant futures together in this space …

Working Paper No. 45, An Intellectual History Of Josiah Warren, Jaye Balentine

Working Papers in Economics

This inquiry seeks to establish that Josiah Warren (1798-1874) developed a synthesis of anti-capitalist economics and radical individualism which became a unique, yet highly practical strand of anarchism in the United States. This inquiry relies heavily upon Crispin Sartwell’s The Practical Anarchist: Writings of Josiah Warren (2011) for insight into Warren’s contributions. Warren registers as distinct because of his relative isolation from other anarchist thinkers, existing largely as a lone practitioner operating in the western territories of the United States during middle-part of the 19th century. This inquiry considers Warren’s philosophical views as well as his practical program—namely his doctrines …

Revisiting The Role Of Physicians In Assisted Living And Residential Care Settings, Sarah Dys, Lindsey Smith, Ozcan Tunalilar, Paula C. Carder

Institute on Aging Publications

As the United States population ages, a higher share of adults is likely to use long-term services and supports. This change increases physicians’ need for information about assisted living and residential care (AL/RC) settings, which provide supportive care and housing to older adults. Unlike skilled nursing facilities, states regulate AL/RC settings through varying licensure requirements enforced by state agencies, resulting in differences in the availability of medical and nursing services. Where some settings provide limited skilled nursing care, in others, residents rely on resident care coordinators, or their own physicians to oversee chronic conditions, medications, and treatments. The following narrative …

Marine Reservoir Effects In Seal (Phocidae) Bones In The Northern Bering And Chukchi Seas, Northwestern Alaska, Joshua Reuther, Scott Shirar, Owen Mason, Shelby L. Anderson, Joan B. Coltrain, Adam Freeburg, Peter Bowers, Claire Alix, Christyann M. Darwent, Lauren Y.E. Norman

Anthropology Faculty Publications and Presentations

We explore marine reservoir effects (MREs) in seal bones from the northern Bering and Chukchi Seas regions. Ringed and bearded seals have served as dietary staples in human populations along the coasts of Arctic northeast Asia and North America for several millennia. Radiocarbon (¹⁴C) dates on seal bones and terrestrial materials (caribou, plants seeds, wood, and wood charcoal) were compared from archaeological sites in the Bering Strait region of northwestern Alaska to assess MREs in these sea mammals over time. We also compared these results to ¹⁴C dates on modern seal specimens collected in AD 1932 and …

From Forests To Fish: Mercury In Mountain Lake Food Webs Influenced By Factors At Multiple Scales, Ariana M. Chiapella, Collin A. Eagles-Smith, Angela L. Strecker

Environmental Science and Management Faculty Publications and Presentations

Mountain lakes, while seemingly pristine, have been subjected to historical fish stocking practices and exposure to atmospherically deposited contaminants like mercury. Mercury bioaccumulation in these ecosystems varies widely due to strong environmental gradients, and there are complex, hierarchical factors that affect mercury transport and loading, methylmercury production, and food web biomagnification. We sought to assess how representative variables associated with watershed, lake, and food web-scale processes—specifically, catchment tree cover, lake benthic primary production, and fish diet, respectively—are associated with mercury concentrations in mountain lake fish. Mean fish mercury concentrations varied threefold between lakes, with nearshore tree cover and fish diet …

Stopped Listening: Experiences Of Higher Education Refugee-Background Learners, Peggy Lynn Maclsaac, Staci B. Martin, Wilson Kubwayo, Chablue Wah, Salome Nanyenga

School of Social Work Faculty Publications and Presentations

This paper discusses the academic agency of refugee-background individuals who have resettled to the United States of America and the responsibility of higher education to value refugee-background learners as knowledge creators. Contrary to deficit thinking that views learners as unable to succeed due to their refugee background, this study explores how their experiences demonstrate their multiple capacities to succeed in higher education. The essence of these experiences is presented using self-reflexive collaborative speaking and writing inquiry. Three main themes drawn from the results were the capacities of refugee-background learners to adapt cultures, maintain multiple social connections, and exercise agency.

One Health And Neglected Tropical Diseases—Multisectoral Solutions To Endemic Challenges, Jennifer K. Peterson, Jared Bakuza, Claire J. Standley

University Honors College Faculty Publication and Presentations

One Health is defined as an approach to achieve better health outcomes for humans, animals, and the environment through collaborative and interdisciplinary efforts. Increasingly, the One Health framework is being applied to the management, control, and even elimination of neglected tropical diseases (NTDs). NTDs are a set of debilitating and often chronic infectious diseases that, collectively, affect more than one billion people in almost 150 countries, with disproportionate impact on the extremely poor [1,2]. In this Special Issue, we present a diverse body of work united under the One Health ideology and a desire to mitigate …

The study includes analyses of population, housing and enrollment, and forecasts of district‐wide school enrollments for the 2021‐22 to 2030‐31 school years. Due to the unusual circumstances of the COVID‐19 pandemic, the base, or “launch” year for the forecasts is 2019‐20, not 2020‐21.

Anatomy Of Disaster Recoveries: Tangible And Intangible Short-Term Recovery Dynamics Following The 2015 Nepal Earthquakes, Jeremy Spoon, Chelsea E. Hunter, Drew Gerkey, Ram Bahadur Chhetri, Alisa Rai, Umesh Basnet, Anudeep Dewan

Anthropology Faculty Publications and Presentations

The April/May 2015 Nepal earthquakes and aftershocks had catastrophic impacts on rural households living in biophysical extremes. Recoveries from natural hazards that become disasters have tangible and intangible short- and long-term dynamics, which require linked quantitative and qualitative methods to understand. With these premises in mind, we randomly selected 400 households in two accessible and two inaccessible settlements across two of the highest impacted districts to assess variation in household and settlement recoveries through tangible impacts to infrastructure and livelihood and intangible impacts to place attachment and mental well-being. We conducted household surveys, in-depth interviews, and focus groups over two …

Robust Maximum Coverage Facility Location Problem With Drones Considering Uncertainties In Battery Availability And Consumption, Darshan Chauhan, Avinash Unnikrishnan, Miguel Figliozzi, Stephen D. Boyles

Civil and Environmental Engineering Faculty Publications and Presentations

Given a set of spatially distributed demand for a specific commodity, potential facility locations, and drones, an agency is tasked with locating a prespecified number of facilities and assigning drones to them to serve the demand while respecting drone range constraints. The agency seeks to maximize the demand served while considering uncertainties in initial battery availability and battery consumption. The facilities have a limited supply of the commodity being distributed and also act as a launching site for drones. Drones undertake one-to-one trips (from located facility to demand location and back) until their available battery energy is exhausted. This paper …

“We Were Queens.” Listening To Kānaka Maoli Perspectives On Historical And On-Going Losses In Hawai’I, Antonia R.G. Alvarez, Val. Kanuha, Maxine K.L. Anderson, Cathy Kapua, Kris Bifulco

School of Social Work Faculty Publications and Presentations

This study examines a historical trauma theory-informed framework to remember Kānaka Maoli (Native Hawaiian) and lesbian, gay, bisexual, transgender, queer, and/or māhū (LGBTQM) experiences of colonization in Hawai`i. Kānaka Maoli people and LGBTQM Kānaka Maoli face health issues disproportionately when compared with racial and ethnic minorities in Hawai’i, and to the United States as a whole. Applying learnings from historical trauma theorists, health risks are examined as social and community-level responses to colonial oppressions. Through the crossover implementation of the Historical Loss Scale (HLS), this study makes connections between historical losses survived by Kānaka Maoli and mental health. Specifically, this …

The Media Industry In Oregon: Incentive And Impact Analysis 2020 Update, Emma Brophy, Peter Hulseman, Northwest Economic Research Center

Northwest Economic Research Center Publications and Reports

Oregon’s media industries have become increasingly well-known over the last several years, thanks in large part to successful feature length films and television series produced in the state. It is widely known that such productions offer visibility, tourism interest, and a boost to local merchants during their visits. More economically important, but less immediately obvious, are the impacts of a home grown industry of professionals and businesses that thrive in regions able to maintain a reliable stream of production activity. Numerous states now offer incentives to visiting media productions, some focused on big-ticket features and visiting series. In Oregon, the …

Predictors Of Opioid And Alcohol Pharmacotherapy Initiation At Hospital Discharge Among Patients Seen By An Inpatient Addiction Consult Service, Honora Englander, Caroline King, Christina Nicolaidis, Devin Collins, Alisa Patten, Jessica Gregg, P. Todd Korthuis

School of Social Work Faculty Publications and Presentations

Background:

Medications for opioid use disorder (MOUD) and alcohol use disorder (MAUD) are effective and under-prescribed. Hospital-based addiction consult services can engage out-of-treatment adults in addictions care. Understanding which patients are most likely to initiate MOUD and MAUD can inform interventions and deepen understanding of hospitals’ role in addressing substance use disorders (SUD).

Objective:

Determine patient- and consult-service level characteristics associated with MOUD/MAUD initiation during hospitalization.

Methods:

We analyzed data from a study of the Improving Addiction Care Team (IMPACT), an interprofessional hospital-based addiction consult service at an academic medical center. Researchers collected patient surveys and clinical data from September …

Projected Impact Of Mid-21st Century Climate Change On Wildfire Hazard In A Major Urban Watershed Outside Portland, Oregon Usa, Andy Mcevoy, Max Nielsen-Pincus, Andres Holz, Arielle J. Catalano, Kelly E. Gleason

Environmental Science and Management Faculty Publications and Presentations

Characterizing wildfire regimes where wildfires are uncommon is challenged by a lack of empirical information. Moreover, climate change is projected to lead to increasingly frequent wildfires and additional annual area burned in forests historically characterized by long fire return intervals. Western Oregon and Washington, USA (westside) have experienced few large wildfires (fires greater than 100 hectares) the past century and are characterized to infrequent large fires with return intervals greater than 500 years. We evaluated impacts of climate change on wildfire hazard in a major urban watershed outside Portland, OR, USA. We simulated wildfire occurrence and fire regime characteristics under …

"Through A Forest Wilderness:” Native American Environmental Management At Yosemite And Contested Conservation Values In America’S National Parks, Rochelle Bloom, Douglas Deur

Anthropology Faculty Publications and Presentations

Chapter 9. The philosophies and views of nature prevalent in the 19th century West shaped the early National Park Service, and continue to influence park policy today. Park-builders incorrectly viewed early parks as untouched “wilderness,” even as Native peoples continued to occupy, revere, and actively manage lands and resources on these lands. This misapprehension fostered the creation and enforcement of park regulations meant to protect wild spaces, resulting in the displacement of both Native peoples and the culturally significant habitats that they had helped sustain for millennia. Among these regulations, federally imposed restrictions on burning and other traditional plant community …
