Community Gis Workshop Design & Delivery: Columbia County Geographic Workshop At Scappoose Public Library, Marty Marquis

Masters in GIS Practicum Reports

Geographic information systems (GIS) provide tools for industry, government, and the public to describe, visualize and organize space both conceptually and materially. Because the technology is complicated and potentially expensive, it is often out of the reach of those communities that might most benefit from its use, even as it’s routinely wielded by business interests, bureaucrats, and representative bodies to identify and legitimize administrative boundaries, potential areas for growth and profit, spatially oriented legislation (restricted areas, zoning), and so forth. Communities whose members know how to use a GIS gain potential advantages in deploying narratives that contest official plans for …

#Onygo, Géraldine Blattner, Amanda Dalola, Stéphanie Roulon

PDXOpen: Open Educational Resources

#OnYGo is an innovative first-year French language e-textbook, designed as Open Educational Resource (OER), for learning beginning French (equivalent to one year at an American university). It is inspired by a remix of task-based, multiliteracies and communicative approaches, which provides students with opportunities to engage with French language and culture in a variety of contexts and situations, across a range of modalities. Through a wide range of activities, students develop and practice their language skills, and reflect on their cross-cultural knowledge and positionality in their understanding of the vast francophone landscape. #OnYGo is a first-year textbook that takes a DEI-forward …

Theorizing The Korean Wave| K(Q)Ueer-Pop For Another World: Toward A Theorization Of Gender And Sexuality In K-Pop, Jungmin Kwon

School of Film Faculty Publications and Presentations

This article argues that the K-pop space, which on one level appears to be homogeneously cishetpatriarchal, actually encompasses multiple configurations of gender and sexual identity. Nonetheless, academic discussions about gender and sexuality in K-pop have been significantly weighted toward the idea of “soft masculinity” regarding male performers, thereby muffling other possible interpretations. I suggest a new term, K(Q)ueerness. It means the aesthetics, imaginations, practices, performances, and ideas of K-pop players sublate binaristic identifications, including masculinity and femininity and heterosexual and homosexual—as well as Butler’s distinction between performance and performativity—to embrace the multifarious expressions of gender and sexuality surrounding K-pop. This …

Perspectives From Frontline Organizations In The Portland Metro Region On Addressing Food Insecurity During The Covid-19 Pandemic, Megan Horst, Meg Grzybowski, Huijun Tan

Institute of Metropolitan Studies Publications

See video of related event: https://pdxscholar.library.pdx.edu/metropolitianstudies/155/

The main goal of this project was to contribute to an understanding of how frontline-serving food security organizations in the Portland region adapted during the COVID-19 pandemic and other emergencies in 2020-2022 and how they addressed increased rates of food insecurity among the region’s residents. We discuss the experiences of these organizations in serving the region’s food insecure residents, the many adaptations they made in the past few years, barriers experienced, and positive and critical reflections on local government.

Direct Care Staff Experiences In Oregon Assisted Living, Residential Care And Memory Care Communities, 2022, Paula Carder, Sarah Dys, Lindsay Schwartz, Diana Jacoby, Jacklyn N. Kohon, Dani Himes, Madeleine Fox, Sheryl Elliott, Lauren Bouchard, Portland State University Institute On Aging

Institute on Aging Publications

Resident care assistants (e.g., direct care workers, caregivers, personal care aides) provide the majority of services to assisted living, residential care and memory care-endorsed (ALF/RCF) residents. They faced significant burdens during the COVID-19 pandemic, which amplified existing challenges in some ALF/RCF communities, yet little is known about their work experiences. This qualitative study collected data through focus group and individual interviews with 21 resident care assistants and 12 external colleagues who have experience hiring, training or managing resident care assistants and other ALF/RCF staff, including registered nurse consultants, staffing agency operators, state policy staff, ALF/RCF community operations managers, and advocates. …

In winter 2023, University Studies formed a working group to develop and pilot embedded career readiness within first year general education courses. The working group collaborated to create and pilot the curriculum in spring 2023. After the pilot, the working group collected and analyzed student, faculty, and mentor observations and course evaluation data, identified key themes, made recommendations, and created an online repository and website interface for career readiness curriculum and resources.

The working group and pilot participants successfully developed curriculum and piloted it in their courses, gained feedback and insight from students, mentors, and faculty, and created resources for …

Taking A Heavier Toll? Racial Differences In The Effects Of Workplace Mistreatment On Depression, Ji Woon Ryu, Erik Gonzalez-Mulé, Ernest H. O'Boyle

Business Faculty Publications and Presentations

Previous studies have found that workplace mistreatment positively relates to depression, a critical mental health disorder. However, it is unknown whether mistreatment affects all individuals’ depressive symptoms equally. Drawing from the hopelessness theory of depression and the stigma literature, we suggest that Blacks suffer from greater depression than Whites when they experience similar levels of workplace mistreatment because Blacks, as members of a racial minority group, are more likely to attribute workplace mistreatment to their race. This, in turn, causes them to make a pessimistic attribution (i.e., attributions that are internal, stable, and global) about themselves that, ultimately, leads to …

Developing A Standard Operating Procedure For Irrigated Agricultural Field Delineation And Irrigation Identification Using Examples From The Oregon-Idaho Border And Central California, Scott Milleson

Masters in GIS Practicum Reports

This practicum draws from experience working as an intern for The Freshwater Trust (an environmental nonprofit organization based in Portland, Oregon) from June to December of 2022. The work performed in this internship involved the delineation of agricultural fields using ArcGIS Online, an online collaborative mapping tool, as well as identifying and assigning irrigation type attributes on the Oregon-Idaho border along the Snake River, and the Deschutes Basin.

The purpose of this practicum project is to create a generalized guide for the delineation of agricultural fields and identification of irrigation type using a standard operating procedure for GIS interns, mapathon …

In particular, the focus is on the impact of mass distribution on drone viability, performance, and sustainability.

Implementing Super-Resolution Of Non-Stationary Tides With Wavelets: An Introduction To Cwt_Multi, Matthew Lobo, David A. Jay, Silvia Innocenti, Stefan A. Talke, Steven Dykstra, Pascal Matte

Civil and Environmental Engineering Faculty Publications and Presentations

Tides are often non-stationary due to non-astronomical influences. Investigating variable tidal properties implies a tradeoff between separating adjacent frequencies (using long analysis windows) and resolving their time variations (short windows). Previous continuous wavelet transform (CWT) tidal methods resolved tidal species. Here, we present CWT_Multi, a Matlab code that: a) uses CWT linearity (via the “Response Coefficient Method”) to implement super-resolution (Munk and Hasselman 1964); b) provides a Munk-Hasselman constituent-selection criterion; and c) introduces an objective, time-variable form of inference (“dynamic inference”) based on time-varying data properties. CWT_Multi resolves tidal species on time-scales of days and multiple constituents per species with …

Contextualizing Patterns In Short-Term Disaster Recoveries From The 2015 Nepal Earthquakes: Household Vulnerabilities, Adaptive Capacities, And Change, Jeremy Spoon, Drew Gerkey, Alisa Rai

Anthropology Faculty Publications and Presentations

Disaster recovery is multidimensional and requires theoretical and methodological approaches from the interdisciplinary social sciences to illustrate short- and long-term recovery dynamics that can guide more informed and equitable policy and interventions. The 2015 Nepal earthquakes have had catastrophic impacts on historically marginalized ethnic groups and Indigenous households in rural locations, arising in the immediate aftermath and unfolding for years afterward. Analyzing factors that shape household recovery patterns can help identify vulnerabilities and adaptive capacities in addition to signaling potential future changes. We pursue this goal using survey data from 400 randomly selected households in 4 communities over 2 10-week …

Conspiracy Theories And Ebola: Lessons Learned Important For Future Pandemics, Shawn C. Smallman

International & Global Studies Faculty Publications and Presentations

The public health campaign against Ebola in the Democratic Republic of the Congo faced serious challenges, some due to conspiracy theories and denial. These beliefs were so powerful that they even caused repeated attacks upon health care providers and medical centers. These conspiracy theories were nothing new, as they are a common feature of all frightening epidemics, such as HIV and COVID-19. These narratives also circulated during the 2015 West African Ebola outbreak. Addressing conspiracy theories during an epidemic requires a coordinated campaign involving not only local leaders but also the cooperation of social media organizations

Network Effects Of Disruptive Traffic Events, Juan Medina, Xiaoyue Cathy Liu

TREC Final Reports

Current traffic management strategies are based on expected conditions caused by recurring congestion (e.g., by time of day, day of week), and can be very effective when provisions are also given for reasonable variations from such expectations. However, traffic variations due to non-recurrent events (e.g., crashes) can be much larger and difficult to predict, making also challenging efforts to identify, measure, and forecast their disruptive effects. This project explores a proactive approach to deploy a tool for managing non-recurrent congestion by identifying and quantifying the effects of disruptive traffic events at a microscopic level using a comprehensive set of data …

New Lidar System Pinpoints Pedestrian Behavior To Improve Eficiency And Safety At Intersections, Taylor Li, Sirisha M. Kothuri, Xianfeng Terry Yang

TREC Project Briefs

Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department of Transportation (UDOT) is already working on implementing this new LiDAR system to improve data collection at intersections.

Unexpected Wins: Curating Comics And Teaching Manga From The Dark Horse Comics Collection, Elsa Loftis, Jon Holt

Library Faculty and Staff Publications and Presentations

A familiar staple of entertainment for a wide variety of readers, the comic book has not always held a regular place in the academic library. Concerning themselves with collecting more traditional expressions of scholarship, libraries have not historically dedicated much of their acquisitions budgets to this area. Therefore, the comic book or graphic novel was largely relegated to someone’s personal collection and would more likely be found on the shelves of a comic book store than the shelves of a university library.

Fast-forward to the present day, where library collections more commonly provide access to comic books, either in regular …

The intervention suggests integrating cultural responsiveness practices, remedial education, and outdoor teacher training competency into existing teacher training programs. By adopting this comprehensive approach, new teachers can acquire the necessary tools to meet the diverse needs of their students and adapt to the challenges of modern education. Ongoing professional development programs are also recommended to enable teachers to continuously enhance their skills throughout their careers. This multi-pronged solution aims to establish a more equitable and effective educational system that considers various dimensions of children's …

Trauma‐Informed Care Implementation Assessment Instrument, Karen Cellarius, Aliza Tuttle, Christine A. Da Rosa

Regional Research Institute for Human Services

Trauma Informed Oregon’s Trauma-Informed Care (TIC) Implementation Tool provides a framework for incorporating trauma-informed policies, practices and care into any organization’s structure. It was originally created in 2022 by Trauma Informed Oregon (TIO) and the Human Services Implementation Lab (iLab) at Portland State University’s Regional Research Institute. Implementation of Trauma-Informed Care is an ongoing process and is not expected to happen all at once. Systematically assessing TIC implementation accomplishes two things. First, it documents the extent that the organization is trauma-informed and clearly identifies systemic strengths, weaknesses and gaps. Second, it helps the organization decide on overall goals, and identify …

Implications Of Physical Fault Injections On Single Chip Motes, Sara Faour, Mališa Vučinić, Filip Maksimovic, David Burnett, Paul Muhlethaler, Thomas Watteyne, Kristofer Pister

Electrical and Computer Engineering Faculty Publications and Presentations

Single-chip motes are wireless sensor nodes that integrate computation, communication, power and sensing on a single chip. We consider the security threats these novel devices are subject to when employed in safety-critical applications. Fault injection attacks are a prominent form of physical attacks that pose a threat to the normal and secure functioning of targeted devices, potentially compromising their intended behavior. These attacks have been studied mainly on commercial off-the-shelf devices which rely on external components such as crystal oscillators and passives. Such external components are absent from single-chip motes, resulting in a uniquely different attack surface compared to commercial …

#Blackatcmo: Challenging Charter Schools Through Youth Instagram Counterstories, Madhu Narayanan, Matthew Mccluskey

Educational Leadership and Policy Faculty Publications and Presentations

As protests flared in 2020, Black students took to Instagram to voice their experiences at ‘no-excuses’ Charter Management Organizations (CMOs). Such schools have presented a discourse of high achievement and social justice. Yet, in the span of a few weeks, hundreds of posts on Instagram offered rarely heard counter-narratives of the experience of being a student of Color at such schools. This paper analyzes how social media posts combine online discourse and youth culture to provide insight into the racialized experience of schooling. We show how these posts created distinct visual signatures, co-opted the well-crafted narratives of CMOs, and took …

Employing The Houseless As Corporate Social Responsibility, Nicholas A. Smith, Larry R. Martinez, Shi (Tracy) Xu, Anna Mattila, Lisa Yixing Gao

Purpose

Many hospitality organizations see the benefits of engaging in corporate social responsibility (CSR), which can take many forms. This study aims to examine one relatively unique form of CSR: hiring individuals experiencing houselessness. This research aimed to investigate the impact of hiring individuals experiencing houselessness on customers’ behavioral intentions, attitudes toward an organization and perceptions of CSR actions.

Design/methodology/approach

Across two experiments, this study investigated the impact of employing individuals experiencing houselessness on customers’ perceptions of the employee and organization using organizational legitimacy theory.

Findings

Results demonstrate that employees known to be houseless elicited more positive employee and organizational …

The Daily Association Between Affect And Alcohol Use: A Meta-Analysis Of Individual Participant Data, Jonas Dora, Marilyn Piccirillo, Kelly Arbeau, Stephen Armeli, Marc Auriacombe, Bruce Bartholow, Adriene M. Beltz, Shari M. Blumenstock, Cynthia Mohr, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Influential psychological theories hypothesize that people consume alcohol in response to the experience of both negative and positive emotions. Despite two decades of daily diary and ecological momentary assessment research, it remains unclear whether people consume more alcohol on days they experience higher negative and positive affect in everyday life. In this preregistered meta-analysis, we synthesized the evidence for these daily associations between affect and alcohol use. We included individual participant data from 69 studies (N = 12,394), which used daily and momentary surveys to assess affect and the number of alcoholic drinks consumed. Results indicate that people are not …

An Improved Lower Bound For Sparse Reconstruction From Subsampled Walsh Matrices, Jaroslaw Blasiok, Patrick Lopatto, Kyle Luh, Jake Marcinek, Shravas Rao

Computer Science Faculty Publications and Presentations

We give a short argument that yields a new lower bound on the number of uniformly and independently subsampled rows from a bounded, orthonormal matrix necessary to form a matrix with the restricted isometry property. We show that a matrix formed by uniformly and independently subsampling rows of an N ×N Walsh matrix contains a K-sparse vector in the kernel, unless the number of subsampled rows is Ω(KlogKlog(N/K)) — our lower bound applies whenever min(K,N/K) > logC N. Containing a sparse vector in the kernel precludes not only the restricted isometry property, but more generally the application of those matrices for …

Learned Compressive Representations For Single-Photon 3d Imaging, Felipe Gutierrez-Barragan, Fangzhou Mu, Andrei Ardelean, Atul Ingle, Claudio Bruschini, Edoardo Charbon, Yin Li, Mohit Gupta, Andreas Velten

Computer Science Faculty Publications and Presentations

Single-photon 3D cameras can record the time-of-arrival of billions of photons per second with picosecond accuracy. One common approach to summarize the photon data stream is to build a per-pixel timestamp histogram, resulting in a 3D histogram tensor that encodes distances along the time axis. As the spatio-temporal resolution of the histogram tensor increases, the in-pixel memory requirements and output data rates can quickly become impractical. To overcome this limitation, we propose a family of linear compressive representations of histogram tensors that can be computed efficiently, in an online fashion, as a matrix operation. We design practical lightweight compressive representations …

Panoramas From Photons, Sacha Jungerman, Atul Ingle, Mohit Gupta

Computer Science Faculty Publications and Presentations

Scene reconstruction in the presence of high-speed motion and low illumination is important in many applications such as augmented and virtual reality, drone navigation, and autonomous robotics. Traditional motion estimation techniques fail in such conditions, suffering from too much blur in the presence of high-speed motion and strong noise in low-light conditions. Single-photon cameras have recently emerged as a promising technology capable of capturing hundreds of thousands of photon frames per second thanks to their high speed and extreme sensitivity. Unfortunately, traditional computer vision techniques are not well suited for dealing with the binary-valued photon data captured by these cameras …
