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, …

Fight, Flight, Freeze: How Access To Support Shapes Tenant Responses To Eviction In Multnomah County, Natalie J. Cholula, Lisa K. Bates, Alex Farrington, Marisa Zapata, Colleen Carroll, Jacen Greene, Hadley Bates

Urban Studies and Planning Faculty Publications and Presentations

Facing eviction is a traumatic event that forces tenants into a fight, flight or freeze response. Our focus groups with Multnomah County tenants reveal that their responses to eviction are directly shaped by their access to support. Many tenants are unable to access formal support and therefore respond to eviction by freezing up or fleeing their home. Conversely, tenants who can access formal support—including rental assistance or legal assistance—exhibit a fight response, leveraging external support to challenge or avoid their eviction.

Shame And History, Bennett B. Gilbert

University Studies Faculty Publications and Presentations

If history—our past, the sum of our thoughts, passions, and deeds—is so pervasive, influential, and meaningful, why then do we lose sight of it? Why do we not gain good values from it? And if it is part of our existential core, why then do we so often fail to ravel it into our deliberations?

I propose that very often and to a great degree it is shame that separates us from history. Shame: garrulous, compulsive, intense, omnivorous. A shamed person pushes away the experiences that shame her, thus cutting off the past.

Impacts Of Sex Work Criminalization On Sex Workers In Oregon: A Pilot Study, Stephanie Wahab, Katie Shammel

School of Social Work Faculty Publications and Presentations

Executive Summary

Context for the Study
In July, 2023, Oregon legislators voted to fund research exploring the impacts of the criminalization of sex work in Oregon. Unfortunately, the Governor vetoed the budget item, stating that the private sector should fund this type of public health research and noting the need for additional public discussion about the issue. To date, there have been no attempts to study the impacts of prostitution laws on the people most impacted by them in Oregon. The research presented in this report seeks to address this gap.

This qualitative pilot study was designed to better understand …

Moisture-Controlled Triboelectrification During Coffee Grinding, Joshua Méndez Harper, Yong-Hyun Kim, Robin E. Bumbaugh, Connor S. Mcdonald, Christopher H. Hendon, Elana J. Cope, Leif E. Lindberg, Justin Pham, Multiple Additional Authors

Electrical and Computer Engineering Faculty Publications and Presentations

Triboelectrification is the physical process where materials acquire surface charge from frictional interactions at their interfaces.The magnitude of charge depends on the interfacial material composition and can be harnessed in emergent technologies for energy generation.

The mechanism of electrostatic accumulation is complex and is further obscured in granular materials where collisions are sufficiently energetic to cause fracturing. In this “fractoelectric” regime, crack initiation and propagation are thought to charge particles through transfer of electrons and/or ions at the hot crack interface.

Whether a material’s charging is dominated by tribo- or fractoelectrification, fracture-generated granular flows often comprise particles whose surface charge …

Analyzing Frequency Event Detection Algorithm Performance Using Different Denoising Methods, Hussain A. Alghamdi, Midrar Adham, Robert Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Maintaining grid frequency at its nominal value is crucial for power system stability and supply-demand balance. Swift and accurate detection of frequency events is vital for providing primary frequency response support. Frequency event detection algorithms often rely on Phasor Measurement Unit data, which may contain noise. Implementing a denoising preprocessing step enhances detection precision and accuracy. In previous works, a frequency event detection algorithm based on wavelet transform was developed, which uses discrete wavelet transform (DWT) for denoising purposes. In this paper, several denoising techniques are considered as potential replacements for the current DWT method. This research investigates and compares …

Salvation And Sweet Rolls: An Examination Of Mormon Diet Books, Rachel Noorda

English Faculty Publications and Presentations

Religious diet books highlight the overlap between religious and diet cultures. This article examines the intersection of Mormonism, diet culture, and fatphobia through an analysis of Mormon diet books published between 1990 and 2015. The study explores how Mormon diet books leverage the Word of Wisdom (the LDS health code) to promote weight loss and reinforce religious obedience. By framing dietary compliance as a spiritual mandate, these texts link physical health and body size to moral and spiritual worthiness. This conflation of body and spirit, rooted in Mormon theology, amplifies fatphobia by promoting thinness as a sign of obedience and …

International Bestsellers And The Online Reconfiguring Of National Identity, Rachel Noorda, Millicent Weber, Melanie Ramdarshan Bold

English Faculty Publications and Presentations

International bestsellers are the ideal sites for examining the complicated relationship between literary culture and national identity. Despite the transnational turns in both literary studies and book history, place is still an important configurer of twenty-first-century book reception. Books are crucial to national identity and catalysts of nationalist movements. On an individual level, books enable readers to shape and maintain their own national identities. This Element explores how contemporary readers' understandings of nation, race/ethnicity, gender, and class continue to shape their reading, using as case studies the online reception of three bestseller titles-Liane Moriarty's Big Little Lies (Australia), Zadie Smith's …

The Magmatic Origin Of The Columbia River Gorge, Usa, Nathaniel Klema, Leif Karlstrom, Charles Cannon, Chengxin Jiang, Jim O'Connor, Ray E. Wells, Brandon Schmandt

Geology Faculty Publications and Presentations

Along subduction zones, high-relief topography is associated with sustained volcanism parallel to the plate margin. However, the relationship between magmatism and mountain building in arcs is poorly understood. Here, we study patterns of surface deformation and correlated fluvial knickpoints in the Columbia River Gorge to link long-term magmatism to the uplift and ensuing topographic development of the Cascade Range. An upwarped paleochannel exposed in the walls of the Gorge constrains unsteady deep magma flux, the ratio of intrusive to extrusive magmatic contributions to topography, and the impact of magmatism on Columbia River incision since 3.5 million years ago. Geophysical data …

Polycyclic Aromatic Hydrocarbons (Pahs) In Wildfire Smoke Accumulate On Indoor Materials And Create Post-Smoke Event Exposure Pathways, Aurélie Laguerre, Elliott T. Gall

Mechanical and Materials Engineering Faculty Publications and Presentations

Wildfire smoke contains PAHs that, after infiltrating indoors, accumulate on indoor materials through particle deposition and partitioning from air. We report the magnitude and persistence of select surface associated PAHs on three common indoor materials: glass, cotton, and mechanical air filter media. Materials were loaded with PAHs through both spiking with standards and exposure to a wildfire smoke proxy. Loaded materials were aged indoors over ~4 months to determine PAH persistence. For materials spiked with standards, total PAH decay rates were 0.010±0.002, 0.025±0.005, and 0.051±0.009 d -1 , for mechanical air filter media, glass, and cotton, respectively. PAH decay on …

E Hui Me Ke Kaiāulu: To Connect With The Community, Heather Kayleen Bartlett

Dissertations and Theses

Urban planning literature contains a wealth of knowledge on community engagement as a crucial component of the planning process, yet there remains a notable gap in our understanding of best practices when it comes to sustaining community involvement for ongoing plan implementation. The County of Hawai'i, has charted a unique course through the establishment of Action Committees which serve as an intermediary to uplift grassroots implementation efforts while remaining closely entwined with County resources and processes. This interplay provides a unique case study that results in somewhat of an "identity crisis": Action Committees do not have the autonomy of external …

Dwindling Trust In Experts: A Starting Point For Information Literacy, Mark N. Lenker Iii

Communications in Information Literacy

Librarians and teachers encourage students to include expert perspectives in their research, but recent public discourse includes high-profile examples of experts being inconsistent or wrong, and recent studies suggest that public trust in experts is declining. Waning trust makes it difficult to teach information literacy: I can push students to find high-quality research sources, but what if these sources turn out to be yet another example of experts getting it wrong? After a period of living with this worry, I found a way to move forward by centering class discussion on the public’s dwindling trust in experts. Part of this …

Impact Of Library Instruction Tutorial Format On Student Preference And Performance In First-Year Chemistry, Tara Stieglitz, Lindsey Whitson

Communications in Information Literacy

This research study investigates the effects of library instruction tutorial format (written versus video) on student preference and performance in chemistry education. The authors assessed the format of tutorials used to provide library instruction in an introductory chemistry course by observing 27 student participants as they took in instructions in either a video or a written format and then completed two chemistry information tasks. While participants expressed strong preferences for particular formats, neither the video tutorials nor the written instructions significantly improved task completion speed or performance. Rather, the authors determined that student preference alone is enough to justify the …

It comes at a critical time when COVID-19 has demonstrated the important and essential nature of long-term care work. COVID-19 has also elucidated the challenges of an insufficient workforce and its detrimental impact on the long-term care system’s ability to meet the care needs of those accessing long-term care services. Finally, workforce needs are projected to increase with the impending influx of baby boomers into retirement, making this study a timely effort at …

Information Literacy In English-Language Higher Education Teaching Journals: A Review, Jennifer Masunaga, Lanyi Peng, Tiffanie Ford-Baxter, Kendall Faulkner

Communications in Information Literacy

Wider visibility of information literacy (IL) outside of the library and information science (LIS) field is important to the success of IL instruction, learning, and research. The development and major updates of several information literacy documents in the past decade evidence the changing landscape of IL research, but how these changes have impacted other disciplines remains to be seen. To aid in this discussion, this article examines a wide range of higher education teaching journals to expand on Badke's (2011) work, “Why Information Literacy is Invisible.” Specifically, this study examines articles published in 30 general higher education and 32 …

Critical Online Library Instruction: Opportunities And Challenges, Tessa Withorn

Communications in Information Literacy

Although critical information literacy, critical pedagogy, and online library instruction are commonly discussed in the library and information science literature, they are rarely discussed together. This qualitative interview study with academic librarians conducted in 2022 identifies opportunities and challenges of teaching critical information literacy online. Findings suggest that critical information literacy and critical pedagogy can be integrated into online library instruction through online workshops, digital learning objects, and online credit-bearing courses. However, librarians face challenges implementing critical pedagogy online related to the lack of dialogue and co-creation of knowledge between students and instructors, limitations of the one-shot model of library …

Truth Or Consequences: Academic Instruction Librarians As Information Literacy And Critical Thinking Activists, Laureen P. Cantwell-Jurkovic, Heather F. Ball

Communications in Information Literacy

The graphic edition of Snyder’s On Tyranny (2021) states "truth dies in four modes," which is a contemporary synthesis connected to Klemperer's Language of the Third Reich (1957). The researchers connected these four modes to information literacy (IL) instruction—but would others? The researchers surveyed academic librarians engaged in IL instruction on whether they felt they addressed any of the modes in their work. The researchers also asked whether they believe the ACRL Framework for Information Literacy for Higher Education works to circumvent any of the four modes. Nearly 150 librarians responded and, while most respondents were unfamiliar with the two …

Examining Policy Innovation Process And The Roles Of Policy Entrepreneurs: A Case Of Smart City Initiative In Khon Kaen, Thailand, Thitisak Duadsuntia

Dissertations and Theses

Innovation is a necessary process for public sector organizations and governments to adapt to social and economic changes. Innovation helps governments improve public service performance and address wicked challenges. Although the significance of public sector innovation has long been realized, how it occurs, and how it is influenced by contextual factors is not well explored. Particularly, policy innovation that emerges in an open and dynamic social system is understudied. Policy entrepreneurs mobilize policy change in their social systems, but their roles in a public sector innovation process still needs further investigation.

This study explores the policy innovation process and explicates …

In The Hot Seat: Acquiring Kernel Density Heat Map Design Guidance Through Delphi And Survey Methods, Lauren Eileen Mckinney-Wise

Dissertations and Theses

Kernel density heat maps have emerged as a new, popular thematic map type. Yet, unlike other thematic map types, little if any published guidance exists for effective heat map design. This is significant because maps are highly persuasive objects that are often utilized to communicate important information, but maps can also be misleading and misunderstood. Therefore, proper guidance for heat map creation is critical for cartographers to create maps that convey geographic information successfully.

To address this literature gap, I used a modified Delphi method and an online survey to investigate several questions, including understanding what cartographic experts think are …

Committees In The Oregon State Legislature: Partisan, Distributive, Or Informational, Woodrow C. Moore

Dissertations and Theses

The study of legislative committees has overwhelmingly been focused on the Congressional level. This has left legislative committees at the state level largely unstudied. Committees in the Oregon State Legislature are an essential and powerful part of the policy making process and Oregon is unlike most other states in that bills cannot be amended on the floor. Using three theories regarding legislative committees -- the informational theory, distributive theory, and the partisan theory -- that were put forth by Krehbiel, Cox and McCubbins, and Weingast and Marshall, this paper will examine the Oregon State Legislature's committee system through a series …

Evaluating Militant Decision-Making With Information Science: The Irish Republican Movement During The "Troubles", Joshua C. Eastin, Emily Kalah Gade, Michael Gabbay

Political Science Faculty Publications and Presentations

Why do militant groups decide to escalate or deescalate their use of violence in conflict? Examining the case of the “Troubles” in Northern Ireland, we analyze groups that adopt violence as a political strategy and evaluate factors that influence its application. To do so, we adopt a novel empirical approach to the study of militant groups. Drawn from information science, this approach enables estimation of variable influence and uncertainty within structured case studies, and is thus ideal for topics such as militant decision-making where systematic data collection is difficult.

World Languages and Literatures Faculty Publications and Presentations

This article is an analysis of the Soviet film Tom Soier, an adaptation of Mark Twain’s Tom Sawyer and Huckleberry Finn released in 1936, at the height of the Stalinist period. In the article, the author places the film in the context of the Soviet support of the Black struggle against racial segregation in America by showing how Tom Soier creatively combines the plots of Twain’s novels in order to propagate an antiracist message. Furthermore, by casting African American actors in the roles of Black enslaved characters, the film also engages with what Steven Lee has called the ethnic …

Expanding On The Frames: Making A Case For Algorithmic Literacy, Susan G. Archambault

Communications in Information Literacy

Traditional information literacy skills (e.g., effectively finding and evaluating information) need to be updated due to the rapidly changing information ecosystem and the growing dominance of online platforms that use algorithms to control and shape information. This article proposes additions to the current ACRL Framework for Information Literacy for Higher Education that relate to algorithmic literacy. The “Authority Is Constructed and Contextual” frame can be applied to recognizing the need to question algorithmic authority (including algorithmic bias), the "Information Has Value” frame can be used to acknowledge online platforms’ use of proprietary algorithms allowing third parties to access personal data, …

Patient Mistreatment And New Nurse Adjustment: The Role Of Rumination And Work Engagement, Hai-Jiang Wang, Peikai Li, Talya Bauer, Berrin Erdogan

Business Faculty Publications and Presentations

During organizational entry, newcomers often draw upon internal resources like coworkers and supervisors to navigate their roles. Could external interactions with customers or patients hold the key to newcomer adjustment in certain job contexts? Our study, rooted in the conservation of resources theory, identifies a critical link between mistreatment from external parties and newcomer adjustment—a connection that is explained by rumination and work engagement. Through two studies involving new nurses in China (Study 1: four-wave cross-lagged panel design, N = 181; Study 2: four-wave time-lagged design, N = 198), we uncover that mistreatment from patients results in rumination among newcomers, …
