2023 Oregon Statewide Homelessness Estimates, Jacen Greene, Franklin H. Spurbeck, Marisa Zapata

Homelessness Research & Action Collaborative Publications and Presentations

Executive Summary excerpt:

The Point-In-Time (PIT) count is a census of people experiencing both sheltered and unsheltered homelessness on a single night in January. The federal government requires this as a condition of funding it distributes to Continuums of Care (CoCs), networks of government agencies and service providers that manage homelessness services and funding in specific regions. Oregon has eight CoCs, five of which manage their own PIT count, which leads to variation in methodology and completeness. The PIT count’s accuracy is further reduced because it only captures homelessness on a single night, missing changes throughout the year, and uses …

2023 Point In Time Findings Report: Count Of People Experiencing Homelessness In Clackamas, Multnomah, And Washington Counties, Oregon, Marisa Zapata, Jacen Greene, Carolyn Niehaus, Ethan Sharygin, Franklin H. Spurbeck, Christina Wei

Homelessness Research & Action Collaborative Publications and Presentations

The U.S. Department of Housing and Urban Development (HUD) requires localities to complete an annual census-style count of people experiencing homelessness in their jurisdictions. This count, called the Point in Time (PIT) Count, enumerates the number and characteristics of individuals and family households who are experiencing homelessness. In 2023, the Portland, Oregon tri-county region collaborated for the first time and jointly created, administered, and analyzed the count data. The Tri-County 2023 PIT Count report presents findings from this first regional count of people experiencing homelessness.

The data are delivered in two pipe-delimited text files. Each row represents one county, and columns represent standard data fields described in the codebooks. Oregon Department of Human Services supported the analysis and selected the indicators for production; race/ethnicity are reporting in a manner consistent with …

On Willing Surrender As Virtuous Self-Constitution, Bennett B. Gilbert

University Studies Faculty Publications and Presentations

Our cultural situation is to seek a moral form of self-constitution, rather than an ontological or epistemological foundation. Such a moral ground lies in the paradox of willing surrender of the will to do wrong or dysfunctional acts in order to enter temporally-extended processes of moral change. But the paradox of willing surrender of the will requires analysis. The propositional form of it cannot be sustained and must instead give way to willingness as an ongoing choice. The self-reflexivity of the will with which we accomplish this turns out to be a core activity of human activity that seeks openness …

Full Count Of Eviction Cases Filed In Oregon Available For The First Time, Colleen Carroll, Minji Cho, Lisa K. Bates, Alex Farrington, Azad Amir-Ghassemi, Safia Goldsmith, Jacen Greene

Urban Studies and Planning Faculty Publications and Presentations

Residential eviction cases can be filed in two court types in Oregon, circuit courts and justice courts. Up until now, statewide research on evictions has only included filings in circuit courts, because those court records are accessible through a centralized online database run by the judicial department. Eviction cases can be filed in fourteen justice courts in Oregon. Because each justice court maintains their court’s records onsite, these eviction cases have previously been invisible to researchers and policymakers. This study reports the first-ever full accounting of the number of eviction cases filed in Oregon, including cases filed in both court …

The Intersection Of Asset Management And Geographic Information Systems For University Facilities Maintenance, Andrew Westerlund Beland

Masters in GIS Practicum Reports

This project describes a proof of concept for developing a digital asset management system dashboard for water backflow assemblies at Portland State University (PSU) using a modified ESRI ArcGIS Online backflow solution. Asset management is crucial for optimizing the lifecycle of tangible assets, which ensures cost-effective operational efficiency and regulatory compliance. PSU manages over 250 backflow assemblies spread across the 50-acre campus and has traditionally relied on manual processes, which can lead to inefficiencies and potential transcription errors.

The system links spatial data with asset attributes for backflow devices, enabling field staff to update inspection results directly from mobile devices. …

The product was to be novel, and the plan was to include customer identification, market analysis, generating personas, and a 15-minute presentation at the end of the workshop. The goal was to 'inspire …

Subvert The Dominant Paradigm: Reimagining Academic Library Hiring Processes, Xan Arch, Isaac P. Gilman

Library Faculty and Staff Publications and Presentations

For libraries dedicated to diversity, equity, and inclusion, it is crucial to address firmly-held traditions about “correct” hiring practices. This work of revising traditional practices can be a fraught process, as different stakeholders often hold strong opinions about how best to evaluate candidates and conduct successful searches. To move our two academic libraries toward more inclusive hiring practices, we each led internal processes to entirely revise our hiring manuals. We will discuss the challenges and core issues addressed through this work, and the resulting principles that we believe will result in a more equitable, transparent, and candidate-friendly process.

Demagoguery And The Depression, David Horowitz

History Faculty Publications and Presentations

Taking advantage of the economic devastation wrought by the Great Depression of the 1930s, a variety of colorful personalities advanced a host of panaceas to redress the grievances of ordinary Americans. Although President Franklin D. Roosevelt, Wisconsin progressive Philip La Follette, and the Communist Party were among those on the left tainted with charges of demagoguery, the controversy over the manipulation of uninformed opinion centered on aspiring mass movement leaders such as Louisiana Senator Huey P. Long, radio priest Father Charles E. Coughlin, old-age pension advocate Dr. Francis E. Townsend, agrarian radical William Lemke, and right-wing populist Rev. Gerald L. …

Automation Of Productive Machinery. Bases For An Innovative Business Model, Carlos Guillermo Hernández-Cenzano, Angel Contreras-Cruz, Eduardo Humada-Tello

Engineering and Technology Management Faculty Publications and Presentations

Nowadays, some laboratories perform elastic properties tests for concrete or rock cores using equipment manufactured 50 years ago. The original data collection procedure uses analog and manual recordings, which can cause inaccuracies in the measurements taken during these trials The process is tedious and updated since each trial's measurement data is recorded manually. In this context, this study systematizes the process and proposes an automated data acquisition and recording system for this type of equipment, followed by a case study presenting a rock compression test.

Field Demonstration Of Residential Der Service-Oriented Load Participation, Zhongkai Zeng, Dana Paresa, Midrar Adham, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Amidst a concerning surge in power consumption during peak hours, coupled with heightened power grid instability, and driven by a growing demand for electricity, aggregations of Distributed Energy Resource are becoming a viable means for providing essential reliability services. Electric utility companies have proactively implemented Demand Response programs for decades. These programs employ Direct Load Control methods to enhance power grid stability, achieved by controlling customers’ Distributed Energy Resource during peak hours to reduce power consumption. However, a notable drawback of Direct Load Control has been high unenrollment rates of DR program participants due to customer discomfort. Therefore, the underlying …

Electrical and Computer Engineering Faculty Publications and Presentations

The internet information that is used by the Energy Grid of Things requires both preventative security measures as well as surveillance measures. The preventative security measures include certificates, encryption, and all of the basic security protocols as defined by published standards. The surveillance measures include monitoring information flow activities and evaluating these messages for indications of potential security attacks. We describe in this paper the utilization of a Distributed Trust Model that was developed specifically for monitoring communication within an Energy Grid of Things. The goal for the Distributed Trust Models is to provide a level of aggregate trust that …

A Transverse-Flux Constant Force Mechanism, Gozde Sivka, Bertrand Dechant, Colton Bruce, Jonathan Z. Bird

Electrical and Computer Engineering Faculty Publications and Presentations

A new type of constant force magnet mechanism is presented that relies on the interaction of magnets alone to create a constant force over a prescribed stroke length. It is demonstrated that by using a transverse field path a very uniform radial field along the travel length is created. This can then be used to create a constant force over a long stroke length. The constat force value is shown to be adjustable through the rotation of the stator relative to the translator. The operating principle of the presented transverse-flux constant force mechanism is validated by using 3-D finite element …

App-Based Data Collection To Characterize Latent Transportation Demand Within Marginalized And Underserved Populations, Noelle L. Fields, Courtney Cronley, Stephen Mattingly, Nicole Iroz-Elardo, David Levine, Nithisha Gudipati, Cristine Highfill, Mary Kris Stringfelllow, Anna O'Dell, Rebecca Cole, Melody Huslage

TREC Final Reports

Our interdisciplinary team refined an app prototype, MyAmble, to gather data related to quantity of transportation disadvantage and latent demand, and to identify psycho-social-economic corollaries. MyAmble utilizes a traditional travel diary format but expands the type of trips measured to include 1) completed trips, 2) missed trips, and 3) latent travel demand. The app also measures the real-time perceived impact of transportation behaviors (realized and latent) on participants’ physical health, mental health, social engagement, and employment/academics. Finally, the app has a text-messaging feature, Travel Buddy, that is used to increase participant engagement and retention over longitudinal data collection. The project …

Unjust And Unsafe: The Eviction Experiences Of Latine Immigrant And Farmworker Tenants In Oregon, Natalie J. Cholula, Lisa K. Bates, Alex Farrington, Marisa Zapata, Jacen Greene, Azad Amir-Ghassemi, Colleen Carroll

Sociology Faculty Publications and Presentations

Latine immigrant households often face housing instability due to language barriers, immigration status, and limited access to government resources. Oregon farmworkers experience additional obstacles to safe and stable housing caused by low wages, a lack of affordable housing options, and social isolation. In light of the identified needs and lack of equitable access to resources that this group experiences, the Evicted in Oregon research team conducted focus groups with Latine immigrant and farmworker tenants in Multnomah, Washington, and Marion Counties. The aim was to gain insight into their experiences with eviction and understand how they navigated through evictions during the …

Path Instabilities And Drag In The Settling Of Single Spheres, Facundo Cabrera-Booman, Nicolas Plihon, Mickael Bourgoin

Mechanical and Materials Engineering Faculty Publications and Presentations

The settling behavior of individual spheres in a quiescent fluid was studied experimentally. The dynamics of the spheres was analyzed in the parameter space of particle-to-fluid density ratio (Γ) and Galileo number (Ga), with Γ ∈ (1.1,7.9) and Ga ∈ (100,340). The experimental results showed for the first time that the mean trajectory angle with the vertical exhibits a complex behavior as Ga and Γ are varied. Numerically predicted regimes such as Vertical Periodic for low Γ values, and Planar Rotating for high Γ values were validated. In particular, for the denser spheres, a clear transition from planar to non-planar …

Screening Tools For Employment In Clinical Healthcare Delivery Systems: A Content Analysis, Mina Colon, Julia M. Goodman

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background The relationship between work and health is complex and bidirectional, where work can have both health-harming and health-enhancing effects. Though employment is recognized as a social determinant of health, and clinical healthcare delivery systems are increasingly using screening tools to ask patients about social needs, little research has explored the extent to which employment-related social risk is captured in these screening tools. This study aimed to identify and characterize employment- and work-related questions in social risk screening tools that have been implemented in clinical healthcare delivery systems.

Methods We conducted a qualitative content analysis of employment-related items in screening …

Urban Streetscape Changes In Portland, Oregon: A Longitudinal Virtual Audit, Tomoya Hanibuchi, David Banis, Hunter Shobe, Tomoki Nakaya, Shohei Nagata

Geography Faculty Publications and Presentations

Streetscape imagery has considerable potential for observing urban change. The literature lacks sufficient longitudinal studies, however, on urban change considering human perception and activities. We conducted a longitudinal virtual audit to observe the change in urban liveliness, human activities, and built environment by examining streetscape imagery taken in the late 2000s and the late 2010s in Portland, Oregon. Eleven untrained crowd workers were recruited to provide liveliness ratings of 24,242 streetscape images for both periods. Tabulation, mapping, and multilevel regression analyses were conducted to observe the distribution, changes in liveliness, and the factors affecting these changes. The results confirmed that …

Scales Of Connectivity Within Stream Temperature Networks Of The Clackamas River Basin, Oregon, Michael Krochta, Heejun Chang

Geography Faculty Publications and Presentations

Water quality varies along the stream network; thus, considering the directional, dendritic nature of stream networks with surrounding landscape variables is essential in explaining spatial variations of water quality. Using a spatially extensive stream temperature monitoring effort in the Clackamas River Basin in the United States, we first compare spatial scales of analysis of atmospheric, landscape, and in-stream explanatory variables through their correlation with summer stream temperatures. We then derive a predictive stream temperature model with factors representing the spatial variation of local climate, recent wildfire effects, and discharge. Finally, we compare nonspatial multiple linear regression to a spatial stream …

Criminology and Criminal Justice Faculty Publications and Presentations

This final report provides the findings of a multi-year project to understand the effects of successive drug policy efforts in Oregon. Since 2013, Oregon has implemented three changes that reclassified and lowered the seriousness of low-level drug possession offenses, with multiple years between each policy change: Justice Reinvestment in 2013, defelonization in 2017, and decriminalization in 2021. This project parses out the individual impacts of these unique events on law enforcement, prosecution, courts and sentencing, and public safety & health.

Data From: Active Transportation Counts From Existing On-Street Signal And Detection Infrastructure, Sirisha Kothuri, Patrick Allen Singleton, Mahyar Vahedi Saheli, Elizabeth Yates, Joseph P. Broach

Civil and Environmental Engineering Faculty Datasets

This study’s objective was to use data from existing traffic signal infrastructure to estimate pedestrian volumes. Pedestrian push-button actuations were collected from signal controller logs at 49 intersections in western Oregon and an additional 16 intersections in eastern Oregon. These actuations were then compared to observed pedestrian counts, totaling over 34,000 people, obtained from video recordings. After exploring various options, a simple quadratic relationship was modeled using a single measure of pedestrian signal activity: the number of push-button presses (filtered to remove multiple presses within 15 seconds). The model’s predictions showed a correlation of 0.86 with observed pedestrian volumes and …

Revisiting Rockafellar’S Theorem On Relative Interiors Of Convex Graphs With Applications To Convex Generalized Differentiation, Boris S. Mordukhovich, Nguyen Mau Nam, Dang Van Cuong, G. Sandine

Mathematics and Statistics Faculty Publications and Presentations

In this paper we revisit a theorem by Rockafellar on representing the relative interior of the graph of a convex set-valued mapping in terms of the relative interior of its domain and function values. Then we apply this theorem to provide a simple way to prove many calculus rules of generalized differentiation for set-valued mappings and nonsmooth functions in finite dimensions. Using this important theorem by Rockafellar allows us to improve some results on generalized differentiation of set-valued mappings in [13] by replacing the relative interior qualifications on graphs with qualifications on domains and/or ranges.

Deep Adaptive Graph Clustering Via Von Mises-Fisher Distributions, Pengfei Wang, Daqing Wu, Chong Chen, Kunpeng Liu, Yanjie Fu, Jianqiang Huang, Yuanchun Zhou, Jianfeng Zhan, Xiansheng Hua

Computer Science Faculty Publications and Presentations

Graph clustering has been a hot research topic and is widely used in many fields, such as community detection in social networks. Lots of works combining auto-encoder and graph neural networks have been applied to clustering tasks by utilizing node attributes and graph structure. These works usually assumed the inherent parameters (i.e., size and variance) of different clusters in the latent embedding space are homogeneous, and hence the assigned probability is monotonous over the Euclidean distance between node embeddings and centroids. Unfortunately, this assumption usually does not hold since the size and concentration of different clusters can be quite different, …

From Provincial Palace To Country Cottage: A History Of The Russian Dacha, 1700s To Present, Melissa Renee Rosenak Bevency

History Undergraduate Departmental Honors Theses

In Russia, the dacha is typically a second home with a garden, located outside of but not far from a major city. However, this definition fails to fully encapsulate the cultural phenomenon, which has transformed in tandem with Russia throughout the years. The dacha's first manifestations appeared during the reign of Peter the Great, the name coming from the verb "to give," as dachas were given as land allotments by the tsar to his servitors. These grand estates were limited to Russia's most elite and were maintained by enserfed peasants. However, in centuries that followed, the dacha became more accessible …
