Co-Create: The People's Guide To The Queens International, Christine Wong Yap, Brian Droitcour

The People's Guide to the Queens International

The People’s Guide to the Queens International was a collaborative art project organized by Brian Droitcour and Christine Wong Yap. We invited the public to write reviews of artworks in the Queens International 2018 exhibition.

We offered many writing prompts, available in a purpose-built writing desk in our installation, prompts available in three Queens Museum galleries, and prompts housed in miniature kiosks with submission boxes at Queens Public Libraries at Flushing, Le Frak City, and at the Central branch in Jamaica. Prompts were available in Chinese, Spanish, and Russian. We also facilitated writing workshops at the museum and libraries.

Mixing Of The Willamette And Columbia Rivers Across Sauvie Island, Oregon Based On Stable Isotopes (Δ18o And Δd) Of Surface Water, Mae Saslaw

Urban Ecosystem Research Consortium of Portland/Vancouver

The stable isotopic composition of surface water (δ18O and δD) is used extensively to constrain water evolution throughout the hydrologic cycle. The isotopic composition of meteoric water varies globally based on latitude, elevation, distance from its source, and environmental conditions during and after precipitation. Existing data show that the isotopic signatures of the Willamette and Columbia Rivers are distinct from one another with δ18O values of approximately -10.5‰ and -16.2‰ respectively. Sauvie Island lies at the confluence of these two rivers. It is an 84.8 km2 floodplain containing wetlands, channels, and lakes. I collected water samples throughout the region, including …

Exploring The Relationship Between Collaborative Partnerships And Outcomes: An In-Depth Look At The Tree For All Program, Rebecca Mclain, Antonia Machado

In 2017, The Intertwine Alliance, Clean Water Services, and the Tualatin River National Wildlife Refuge (TRNWR) embarked on a project with PSU’s Institute for Sustainable Solutions to assess the benefits of collaborative partnerships and identify the factors contributing or hindering their success. The project focused primarily on the Tree for All (TFA) program in the Tualatin River Watershed. Over the course of six months, our team examined three restoration projects in depth, including the Rural Landowners Incentives Program and restoration efforts in the Jackson Bottom Wetlands Preserve and the Fanno Creek Greenway area. Mini case studies of restoration efforts by …

Effective Outreach To Vulnerable And Underserved Communities Through Community Engagement Liaisons (Cels), Jennifer Devlin

Urban Ecosystem Research Consortium of Portland/Vancouver

In 1993, The Oregon Health Authority (OHA) issued a Fish Advisory regarding the consumption of fish from the Columbia Slough. Historically, the Slough was a dumping ground for slaughterhouse, industrial, and chemical waste. These practices resulted in contamination of sediment and fish accumulated with PCB, pesticides, metals, and other pollutants. As part of the Columbia Slough Sediment Program, the City of Portland (City) provides education and outreach regarding the Fish Advisory under Intergovernmental Agreement between the City of Portland and Department of Environmental Quality (DEQ). Results from the most recent fish tissue sampling event by The Columbia Slough Sediment Program …

Relational Thriving In Context: Examining The Roles Of Gratitude, Affectionate Touch, And Positive Affective Variability In Health And Well-Being, Alicia Rochelle Starkey

Dissertations and Theses

Social connection is important to one's health and longevity. However, not only do people need others to survive, we need others to thrive. Researchers call for deeper examination of the functions and processes through which our social partners help us to prosper and thrive, such as through increased physical health and well-being. Over three studies, I examined phenomena theorized to contribute to long-term thriving including positive emotions (i.e., gratitude and positive affect fluctuation), responsive support, affectionate touch, and physical health (i.e., sleep) within the context of nursing work (Study 1) and military relationships (Study 2 & 3). Study 1 provides …

What If Our Beliefs About A System Are Not Wholly Accurate? What If?, Gary Langford

Systems Science Friday Noon Seminar Series

For most people, a system is a construct with vexing complexities, many many parts, and perhaps wrapped with a goal or intention. Add to that simple construct a set of terminologies that are commonly applied when speaking of “systems” and we just might have veered away from discoveries of imminent importance. Ask yourself, “You said it was a system, but how did that statement help you solve your problem? How far off would we have to be in our perception of systemsness for us to make mistakes of consequence? One Hundred Billion are lost annually in software projects that failed …

Try, Try Again: Lessons Learned From Success And Failure In Participatory Modeling, Eleanor J. Sterling, Moira Zellner, Karen E. Jenni, Kirsten Leong, Pierre D. Glynn, Todd K. Bendor, Pierre Bommel, Klaus Hubacek, Antonie J. Jetter, Rebecca Jordan, Laura Schmitt Olabisi, Michael Paolisso, Steven Gray

Engineering and Technology Management Faculty Publications and Presentations

Participatory Modeling (PM) is becoming increasingly common in environmental planning and conservation, due in part to advances in cyberinfrastructure as well as to greater recognition of the importance of engaging a diverse array of stakeholders in decision making. We provide lessons learned, based on over 200 years of the authors’ cumulative and diverse experience, about PM processes. These include successful and, perhaps more importantly, not-so-successful trials. Our collective interdisciplinary background has supported the development, testing, and evaluation of a rich range of collaborative modeling approaches. We share here what we have learned as a community of participatory modelers, within three …

Equalization Of Four Cardiovascular Risk Algorithms After Systematic Recalibration: Individual-Participant Meta-Analysis Of 86 Prospective Studies, Lisa Pennells, Stephen Kaptoge, Angela Wood, Mike Sweeting, Xinghui Zhao, Carlos J. Crespo, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Aims: There is debate about the optimum algorithm for cardiovascular disease (CVD) risk estimation. We conducted head-to-head comparisons of four algorithms recommended by primary prevention guidelines, before and after ‘recalibration’, a method that adapts risk algorithms to take account of differences in the risk characteristics of the populations being studied.

Methods and results: Using individual-participant data on 360 737 participants without CVD at baseline in 86 prospective studies from 22 countries, we compared the Framingham risk score (FRS), Systematic COronary Risk Evaluation (SCORE), pooled cohort equations (PCE), and Reynolds risk score (RRS). We calculated measures of risk discrimination …

This report documents how metropolitan planning organizations (MPO), State departments of transportation (DOT), and other transportation agencies are adapting Environmental Justice (EJ) analysis techniques to understand transportation impacts in communities undergoing rapid demographic change. The report also highlights national demographic trends, showing significant change in the size and location of low-income and minority households. These changes are documented in a series of State- and county-level maps demonstrating absolute and percent change in minority populations, low-income populations and limited English proficiency populations between the 1990 – 2010 decennial census periods. Based on the state of practice review, the report also highlights …

Vehicle To Infrastructure: Letting Cyclists Talk To Signals, Stephen Fickas

TREC Project Briefs

This project demonstrates how an inexpensive system (hardware and software) can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system integrates three components: (1) a Bike Connect box that resides near the signal-controller and is connected to it, (2) an application that runs on a Bike Connect device (currently an iPhone) and requests a green light at the correct approach-distance, and (3) a cloud-based publish/subscribe (pub/sub) component that handles cellular-communication between phone app and box. One stumbling block for the project was a means to obtain reliable GPS data to …

From Knowledge To Practice: Rethinking Streets For People On Bikes, Marc Schlossberg, John Rowell, Roger Lindgren

TREC Project Briefs

For too long we’ve been building streets as though they have one function–to move cars quickly. The reality is that streets can to do more than just move cars. They can move people on foot, on bikes, on transit, without hurting vehicular throughput and safety. They can be more than a way to get somewhere else. Good streets are good places, too – public places where people meet, sit and socialize, conduct business, wander about, play, and more.

Effects Of Phonomotor Treatment On Discourse Production, Joann P. Silkes, Gerasimos Fergadiotis, Rebecca Hunting Pompon, Janaki Torrence, Diane L. Kendall

Speech and Hearing Sciences Faculty Publications and Presentations

Background: Aphasia is an acquired language disorder that makes it difficult for people to produce and comprehend language, with all people with aphasia (PWA) demonstrating difficulty accessing and selecting words (anomia). While aphasia treatments typically focus on a single aspect of language, such as word retrieval, the ultimate goal of aphasia therapy is to improve communication, which is best seen at the level of discourse.

Aims: This retrospective study investigated the effects of one effective anomia therapy, Phonomotor Treatment (PMT), on discourse production.

Methods & Procedures: Twenty-six PWA participated in 60 h of PMT, which focuses on …

“Little Tablets Of Gold”: An Examination Of The Psychological And Social Dimensions Of Prep Among Lgbtq Communities, Christina J. Sun, Kirsten M. Anderson, Kim Toevs, Dayna Morrison, Caitlin Wells, Christina Nicolaidis

OHSU-PSU School of Public Health Faculty Publications and Presentations

There are significant psychological, social, and cultural dimensions to the HIV epidemic in the United States, especially among lesbian, gay, bisexual, transgender, and queer (LGBTQ) communities. Biomedical HIV treatment has been shown to impact these dimensions. However, there is little understanding of the real-world psychosocial and sociocultural effects of the latest biomedical HIV prevention strategy, HIV pre-exposure prophylaxis (PrEP). This study explored the psychosocial and sociocultural dimensions of PrEP use among LGBTQ adults. We interviewed 23 LGBTQ adults who were current or former users of PrEP. Results included that PrEP users’ experiences were shaped by multiple forms of stigma. Participants …

California Groundwater Management, Science-Policy Interfaces, And The Legacies Of Artificial Legal Distinctions, David Owen, Alida Cantor, Nell Green Nylen, Thomas Harter, Michael Kiparsky

Geography Faculty Publications and Presentations

California water law has traditionally treated groundwater and surface water as separate resources. The 2014 Sustainable Groundwater Management Act (SGMA) broke with this tradition by requiring groundwater managers to avoid significant and unreasonable adverse impacts to beneficial uses of surface water. This paper considers the trajectory of this partial integration of science, law, and resource management policy. Drawing on legal analysis and participatory workshops with subject area experts, we describe the challenges of reconciling the separate legal systems that grew out of an artificial legal distinction between different aspects of the same resource.

Our analysis offers two main contributions. First, …

Knowledge, Principal Support, Self-Efficacy, And Beliefs Predict Commitment To Trauma-Informed Care, Stephanie A. Sundborg

School of Social Work Faculty Publications and Presentations

Objective: Organizations are identifying trauma-informed care (TIC) as a priority yet implementation is slow. Research suggests commitment to a change effort is an important predictor for change behavior; however, there is little theoretical or empirical evidence exploring commitment to TIC. This study examines the variables that predict affective commitment to TIC including foundational knowledge, principal support, self-efficacy, and beliefs about trauma. Does foundational knowledge independently predict affective commitment to TIC or is this relationship mediated by other variables? Method: Data were collected from 118 participants working in human services, using cross-sectional survey design. Participants completed self-report measures of affective commitment …

Caring For The Elderly At Work And Home: Can A Randomized Organizational Intervention Improve Psychological Health?, Ellen Ernst Kossek, Rebecca J. Thompson, Katie M. Lawson, Todd Bodner, Matthew B. Perrigino, Leslie B. Hammer, Orfeu M. Buxton, David M. Almeida, Phyllis Moen, David Hurtado, Bradley Wipfli, Lisa Berkman, Jeremy W. Bray

Psychology Faculty Publications and Presentations

Although job stress models suggest that changing the work social environment to increase job resources improves psychological health, many intervention studies have weak designs and overlook influences of family caregiving demands. We tested the effects of an organizational intervention designed to increase supervisor social support for work and nonwork roles, and job control in a results-oriented work environment on the stress and psychological distress of health care employees who care for the elderly, while simultaneously considering their own family caregiving responsibilities. Using a group-randomized organizational field trial with an intent-to-treat design, 420 caregivers in 15 intervention extended-care nursing facilities were …

The Role Of Teacher Autonomy Support Across The Transition To Middle School: Its Components, Reach, And Developmental Effects, Julia Sara Dancis

Dissertations and Theses

Building upon self-determination theory, this study sought to ascertain the reach of teacher autonomy support beyond its well-documented impact on student autonomy and engagement to include student competence and relatedness, as well as to parse apart specific teacher behaviors that comprise autonomy support (i.e., respect, choice, relevance, coercion) and their unique influences on the multiple motivational outcomes, surrounding the transition to middle school. These questions were examined using information from 224 fifth graders, 339 sixth graders, and 345 seventh graders attending elementary and middle schools in a predominantly Caucasian working and middle class school district.

Regression analyses, predicting change in …

Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang

TREC Webinar Series

Although connected vehicles (CVs) will soon go beyond testbeds, CVs and human-driven vehicles (HVs) will co-exist over a long period. Hence, it is critical to consider the interactions between these two types of vehicles in traffic flow modeling. In this study, we aim to develop a macroscopic model to understand how CVs would impact HVs in the traffic stream. Grounded on the second-order traffic flow model, we study the relationships among flow, density, and speed by two sets of formulations for the groups of CVs and HVs, respectively. A set of friction factors, which indicate CVs' impact to HVs, are …

Community-Engaged Teaching: Lessons From A Participatory History Project, Amie Thurber, Sarah V. Suiter

School of Social Work Faculty Publications and Presentations

How can we create opportunities for students to gain experience in community-engaged scholarship that truly benefits the community given the constraints of the academic calendar, students’ varied capacity to develop reciprocal and responsive community relationships, and the tendency for community-engaged research to instrumentalize community partners in service to academic deliverables? This paper explores one attempt to meet this challenge: an experimental graduate course in community development that linked course content to a participatory history project. Designed as a Scholarship of Teaching and Learning (SoTL) study, instructors studied the instructional process as well as outcomes for students and community partners. We …

Stigmatization And Mental Illness: The Communication Of Social Identity Prototypes Through Diagnosis Labels, Justin Samuel Leverett

Dissertations and Theses

This study tested whether participants exposed to a vignette describing an individual experiencing symptoms of depression, which included only the specific diagnosis label of "depression," would report significantly less stigmatized responses than participants exposed to an otherwise identical vignette which included only the non-specific diagnosis label "mental illness." The study is grounded in past research on stigmatization of mental illness and is informed by three theoretical frameworks, the social identity perspective, attribution theory, and labeling theory. Participants were randomly assigned to read one of the two alternate vignettes, then respond to a series of measures testing desire for social distance, …

Frequency Of Social Contact In-Person Vs. On Facebook: An Examination Of Associations With Psychiatric Symptoms In Military Veterans, Alan R. Teo, Benjamin K. Chan, Somnath Saha, Christina Nicolaidis

School of Social Work Faculty Publications and Presentations

Introduction: Social isolation is closely associated with negative mental health outcomes. Social media platforms may expand opportunities for social contact, but whether online interactions are as effective as face-to-face, or in-person, interactions at protecting against the negative effects of social isolation is unclear.

Methods: Participants consisted of U.S. military veterans who served since September 2001 and used Facebook (n = 587). Our independent variables were frequency of social contact occurring in-person and on Facebook. Dependent variables were probable psychiatric disorders and suicidality, measured using several validated screening tools. The independent effect of each form of social contact was assessed using …

Dc-Rts Noise: Observation And Analysis, Benjamin William Hendrickson

Dissertations and Theses

Dark current random telegraph signal (DC-RTS) is a physical phenomenon that effects the performance of solid state image sensors. Identified by meta-stable stochastic switching between two or more dark current levels, DC-RTS is an emerging concern for device scientists and manufacturers as a limiting noise source. Observed and studied in both charge coupled devices (CCDs) and complementary metal-oxide-semiconductor (CMOS) image sensors, the metastable defects inside the device structure that give rise to this switching phenomenon are known to be derived from radiation damage. An examination of the relationship between high energy photon damage and these RTS defects is presented and …

Latent Space Models For Temporal Networks, Jasper Alt

Systems Science Friday Noon Seminar Series

In many contexts we may expect the structure of networks to be derived from some kind of abstract distance between actors. We refer to this phenomenon as homophily: like nodes connect to like. For example, people with similar beliefs may be more likely to form social relations.

We formalize this notion by positioning the nodes in a latent space representing the possible values of the homophilous attributes. Realistically, we should expect latent attributes like beliefs to change over time in some nontrivial way, and the structures of temporal networks to evolve accordingly. We introduce a model of latent space dynamics …
