Five-Step Guide To Writing About African Children: A Satirical Homage To Decolonizing Our Minds And Challenging Stereotypes, Randall Yesmont, Bright Alozie

Black Studies Faculty Publications and Presentations

This essay is a work of satire, in the style of the late Binyavanga Wainaina’s “How to Write About Africa” and Bright Alozie’s “How to Write About Nigeria” and “How to Write About African Women.” In this satirical homage, we explore the pesky stereotypes that often accompany Western perceptions and writings about African children. We hope that stereotypes satirically highlighted in this piece shed light on the dangers of a single story while advocating for the recognition of the humanity, agency, voices, and dignity of African children.

Thorstein Veblen And His Underlying Philosophical Influences, John B. Hall

Economics Faculty Publications and Presentations

This inquiry recognizes Thorstein Veblen first and foremost as a philosopher who advanced a literature in Social Sciences, generally, and Economic Science, in particular. Veblen’s thinking and writing were supported by rich traditions drawn from notable philosophers that included among several: Charles Sanders Peirce, Immanuel Kant, and Friedrich Nietzsche. Relying upon his strong background in Philosophy, he then sought to challenge mainstream, neoclassical economics, especially. As his career developed, he would turn his talents and energies towards advancing ideas that would ultimately prove foundational for heterodox economics and, relatedly, American Institutionalism.

Electromagnetic Fields And Radiation From Localized Current Source Interacting With A Cosmic Axion Field In The Context Of Massive Axion Electrodynamics, Railing Chang, P. T. Leung

Physics Faculty Publications and Presentations

Electromagnetic fields from localized current source interacting with an oscillatory cosmic axion field are studied, accounting for the possibility of a finite photon mass. In particular, focus will be on the dipole radiation from static current sources. The Proca theory is generalized to include the axion field and solutions to the modified EM field equations are obtained to first order in the axion coupling parameter. Analysis of the interplay between the two vanishingly small parameters – the axion mass (via the coupling constant and the oscillating frequency) and the photon mass – is carried out with reference to possible future …

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.

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, …

Accretion Of Warm Chondrules In Weakly Metamorphosed Ordinary Chondrites And Their Subsequent Reprocessing, Alexander M. Ruzicka, Richard C. Hugo, Jon M. Friedrich, Michael Tyler Ream

Geology Faculty Datasets

To better understand chondrite accretion and subsequent processes, the textures, crystallography, deformation, and compositions of some chondrite constituents in ten lithologies of different cluster texture strength were studied in seven weakly metamorphosed (Type 3) and variably shocked ordinary chondrites (Ragland—LL3 S1, Tieschitz—H/L3 S1, NWA 5421—LL3 S2, NWA 5205—LL3 S2, NWA 11905—LL3-5 S3, NWA 5781—LL3 S3, NWA 11351—LL3-6 S4) using optical and electron microscopy and microtomography techniques. Results support a four-stage model for chondrite formation. This includes 1) limited annealing following collisions during chondrule crystallization and rapid cooling in space prior to accretion, as evidenced by olivine microstructures consistent with dislocation …

The Use Of Fluorescence Lifetime Imaging (Flim) For In Situ Microbial Detection In Complex Mineral Substrates, Yekaterina G. Chmykh, Jay Nadeau

Physics Faculty Publications and Presentations

The utility of fluorescence lifetime imaging microscopy (FLIM) for identifying bacteria in complex mineral matrices was investigated. Baseline signals from unlabelled Bacillus subtilis and Euglena gracilis, and Bacillus subtilis labelled with SYTO 9 were obtained using two-photon excitation at 730, 750 and 800 nm, identifying characteristic lifetimes of photosynthetic pigments, unpigmented cellular autofluorescence, and SYTO 9. Labelled and unlabelled B. subtilis were seeded onto marble and gypsum samples containing endolithic photosynthetic cyanobacteria and the ability to distinguish cells from mineral autofluorescence and nonspecific dye staining was examined in parallel with ordinary multichannel confocal imaging. It was found that FLIM …

Assessment Of Avian Community Structure And Habitat Connectivity In The Fanno Creek Corridor Bird Surveys, Habitat Assessment, And Management Recommendations, Grace Hall

Environmental Science and Management Professional Master's Project Reports

Urbanization can significantly impact habitat quality and connectivity for avian communities, decreasing species richness and diversity. However, in highly fragmented habitats, urban parks and riparian zones can provide important habitat corridors for birds that facilitate movement and access to essential resources. On the west side of greater Portland, Oregon, Fanno Creek may serve as a habitat corridor for birds and other local wildlife.

Fanno Creek is a 25-kilometer tributary of the Tualatin River that runs through the cities of Portland, Beaverton, Tigard, and Durham in northwestern Oregon. The land surrounding the creek includes residential, commercial, and industrial properties as well …

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 …

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 …

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 …

American Institution Of Public, K-12 Education: An Institutional Field Under A Complexity Paradigm, Jennifer Jean Joyalle

Dissertations and Theses

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.

Seeing In The Dark: Towards Robust Pedestrian Detection At Nighttime, Afnan Althoupety

Dissertations and Theses

"At some point in the day, everyone is a pedestrian" a message from the National Highway Traffic Safety Administration (NHTSA) about pedestrian safety. In 2020, NHTSA reported that 6,516 pedestrians were killed in traffic crashes and a pedestrian was killed every 81 minutes on average in the United States. In relation to light condition, 77% of pedestrian fatalities occurred in the dark, 20% in daylight, 2% in dusk, and 2% in dawn.

To tackle the issue from a technological perspective, this dissertation addresses the problem of pedestrian detection robustness in dark conditions, benefiting from image processing and learning-based approaches by: …

Emotion Knowledge, Its Applications, And Their Associations With African American Children's Social Relationships With Teachers And Peers In Kindergarten And First Grade, Brielle Emily Petit

Dissertations and Theses

Close and high-quality relationships with teachers and peers are a significant, positive predictor of young children's academic and social-emotional skills, whereas early conflictual relationships can pose various short- and long-term socio-emotional and academic risks. Evidence also suggests that emotion knowledge, or the ways children identify, recognize, and apply emotional labels, are a crucial factor in children's early development including overcoming social-emotional challenges and fostering high-quality interpersonal relationships. Studies examining social relationships and emotion knowledge in early childhood, however, often reveal worrisome differences in between-group comparison designs. Particularly, minoritized children, and most often Black and African American, are associated with poorer …

Tiny Drifters Amidst Global Change: Examining Environmental Drivers, Trophic Impacts, And Management Strategies Of Estuarine Plankton Communities In The Anthropocene, Taylor Nicole Dodrill

Dissertations and Theses

Plankton productivity supports estuarine food webs, and has been tied to the success of fisheries, macroinvertebrates, and cultured shellfish yields. Climate change and alterations to nutrient loads are thought to be influencing plankton assemblages, with toxin-producing harmful algal blooms (HABs) on the rise and nutritional quality of plankton declining globally. These shifts in plankton communities may contribute to low biomass yields and toxin-based closures of important fisheries. The objectives of this dissertation are to identify environmental drivers, trophic impacts, and management strategies to understand and respond to changing estuarine plankton communities. To address these objectives, I used a combination of …
