Re-Evaluating Hypertragulid Diversity In The John Day Basin, Oregon, Usa, Nicholas A. Famoso, Lana K. Jewell
Re-Evaluating Hypertragulid Diversity In The John Day Basin, Oregon, Usa, Nicholas A. Famoso, Lana K. Jewell
Geology Faculty Publications and Presentations
Despite their relative abundance, members of the family Hypertragulidae (Artiodactyla, Mammalia) have proved a conundrum regarding species diversity in the Turtle Cove Member (Oligocene) of the John Day Formation, located in central and eastern Oregon. Three species and two separate genera are described in the area, but previous research lacks statistical support for this level of variation. We use coefficients of variation (V) on measurements of dentition and astragali of hypertragulid specimens designated Hypertragulus hesperius, Hypertragulus minutus, and Nanotragulus planiceps as a metric for determining whether there were multiple species present in the population. Asymptotic and modified signed-likelihood ratio V …

Win Your Race Goal: A Generalized Approach To Prediction Of Running Performance., Sandhyarani Dash
Electrical and Computer Engineering Faculty Publications and Presentations
We introduce a novel approach for predicting running performance, designed to apply across a wide range of race distances (from marathons to ultras), elevation gains, and runner types (front-pack to back of the pack). To achieve this, the entire running logs of 15 runners, encompassing a total of 15,686 runs, were analyzed using two approaches: (1) regression and (2) time series regression (TSR). First, the prediction accuracy of a long short-term memory (LSTM) network was compared using both approaches. The regression approach demonstrated superior performance, achieving an accuracy of 89.13% in contrast, the TSR approach reached an accuracy of 85.21%. …

Searching For Authentic Cultural Engagement In The Classroom, James H. Lyle Jr.
Searching For Authentic Cultural Engagement In The Classroom, James H. Lyle Jr.
Northwest Journal of Teacher Education
Many teachers in the current public education system in the United States do not fully consider the unique societal and cultural aspects of African American and Latinx learners. As a result, many teachers could benefit from developing skills that strengthen their understanding of authentic engagement, cultural competency, and cultural congruency to aid in implementing culturally relevant and sustaining pedagogical practices that benefit the diverse learning styles of these students. Additionally, some African American/Black teachers have adopted a standalone Eurocentric approach to teaching that could further alienate and disenfranchise students of Color. To address these issues, I describe and explain the …
Critical Conversations On Teaching And Learning Decolonial Narratives: A Duoethnography Of Firekeeper’S Daughter, Erica England, Shain Wright, Dion Crommarty
Critical Conversations On Teaching And Learning Decolonial Narratives: A Duoethnography Of Firekeeper’S Daughter, Erica England, Shain Wright, Dion Crommarty
Northwest Journal of Teacher Education
Exploring the role of diverse young adult (YA) literature in fostering social justice awareness, this paper focuses on the YA novel Firekeeper’s Daughter as a tool for understanding decolonization and our own individual privileges and responsibilities as they relate to colonization. Three researchers, each with differing positionalities and worldviews, employ a polyvocal methodology of duoethnography to examine the text's challenges to settler colonialism and its illumination of historical and systemic injustices. Through our dialogic exchange, we aim to contribute to a wider conversation about the potential of literature storytelling, and authentic, vulnerable conversations to inspire transformative change.

Exploring Teacher Perspectives Of Stem Outreach Sessions, Jennifer M. Jakobi, Rebecca Mccullough, Sabre Cherkowski, Haizley Trevor-Smith
Northwest Journal of Teacher Education
Teachers have a responsibility to create and foster engaging learning environments which encourage underrepresented persons in Science, Technology, Engineering, and Mathematics (STEM). Outreach programs have been shown to increase STEM engagement of students. We use a positive psychology lens to investigate STEM outreach and teacher wellbeing. This exploratory study uses a survey and focus group to assess how a STEM outreach program can create teacher feelings of support, confidence, and enjoyment. Results demonstrate that most teachers felt more confident in teaching STEM following the STEM-mentor facilitated outreach sessions. The positive benefits to teacher wellbeing from outreach program mentorship, is discussed.
Promoting Equity In Culturally Diverse Schools: A Literature Review Of Third Space Pedagogy, Sarah E. Harrison, Heidi Curtis
Promoting Equity In Culturally Diverse Schools: A Literature Review Of Third Space Pedagogy, Sarah E. Harrison, Heidi Curtis
Northwest Journal of Teacher Education
The increasingly culturally diverse settings present within today’s P-12 schools necessitate improved pedagogical practices to develop more culturally inclusive and equitable learning environments. Third-space pedagogical practices demonstrate potential as an approach for increasing educational equity by promoting cultural hybridity among diverse students and stakeholders through negotiated sociocultural perspectives and interactions. This literature review summarizes recent scholarship surrounding third-space pedagogy, including discussions of how educators can foster third-space relationships and design third-space learning opportunities in diverse educational settings. In addition, lessons from COVID-19 third-space learning opportunities are discussed as a model for re-envisioning equitable instructional practices post-pandemic.

Teacher Retention Challenges: What We Learned Before And After Covid-19, Brenda Morton, Edd., Joel Maresh Edd
Northwest Journal of Teacher Education
The COVID-19 pandemic exacerbated the already elevated stress levels among teachers, leading to contemplation of leaving the profession. As educators were compelled to transition to online teacher, they suddenly found themselves immersed in the households of their students, an entirely novel experience. This newfound proximity granted teachers insight into various aspects of the students’ lives, including family dynamics, home environments, levels of household stress, and the accessibility of essential resources. In addition to the teaching duties, educators were tasked with the development of online curricula, the acquisition of online learning resources, and providing support to parents and families during a …

Education And Tolerance Of Homosexuality In Diverse Islamic Contexts, Camila Swift
Education And Tolerance Of Homosexuality In Diverse Islamic Contexts, Camila Swift
Dissertations and Theses
This study examines the relationship between educational attainment and moral tolerance of homosexuality among Muslims in Algeria, Malaysia, Pakistan, and Turkey. Utilizing human development theory to understand how educational attainment affects social values, the analysis draws on data from over 5,000 respondents from the Pew Research Center's "World's Muslims" dataset, which includes responses from a nationally representative sample of Muslims in these four countries. Logistic regression models and predicted probabilities are used to explore how educational attainment relates to moral tolerance of homosexuality, adjusting estimates for various alternate explanations through the use of control variables. The findings reveal that the …

Rock glaciers support alpine biodiversity and may respond more slowly to warming than snow or glaciers. While responses of snow and glaciers to climate change are relatively well understood, a robust assessment of rock glacier environmental niche, future distributions of rock glaciers and potential for development of rock glaciers from current glaciers is lacking. Using process-relevant, high-resolution environmental descriptors, we develop a species distribution model of the topographic, geologic and hydroclimatic niche of rock glaciers that provides novel estimates of potential rock glacier distributions for different climates. We identify mean annual air temperature and headwall area as the dominant controls …

Criminology and Criminal Justice Faculty Publications and Presentations
Police are more likely to be perceived as legitimate when officers are procedurally just during interactions with the public (i.e. impartial, transparent, fair and respectful). Efforts to reinforce these skills have largely focused on contacts initiated by officers. Less attention has been paid to interactions with crime victims. Moreover, in recent years many police departments have sought to increase efficiency by directing victims to report online, rather than communicating directly with an officer. Very little is known about how victims experience online reporting systems. This study surveyed 1,198 property crime victims who used a large US police department’s online reporting …

H2d: Hierarchical Heterogeneous Graph Learning Framework For Drug-Drug Interaction Prediction, Ran Zhang, Xuezhi Wang, Sheng Wang, Kunpeng Liu, Yuanchun Zhou, Pengfei Wang
Computer Science Faculty Publications and Presentations
Accurately predicting Drug-Drug Interactions (DDIs) is critical to designing effective drug combination therapies. Recently, Artificial Intelligence (AI)-powered DDI prediction approaches have emerged as a new paradigm. However, most existing methods oversimplify the complex hierarchical structure within molecules and overlook the multi-source heterogeneous information external to molecules, limiting their modeling and predictive capabilities. To address this, we propose a Hierarchical Heterogeneous graph learning framework for DDI prediction, namely H2D. H2D employs an internal-toexternal, local-to-global hierarchical perspective, exploiting intramolecular multi-granularity structures and inter-molecular biomedical interactions to mutually enhance across hierarchical levels. Extensive experimental results demonstrate H2D’s effectiveness on three …

In the wake of the COVID-19 pandemic, the crisis in Palestine, and the continued rise in hate crimes against Asian American and Pacific Islander (AAPI) communities, clinical social work praxis centering on the intersectional identities of queer and transgender AAPI communities has never been more vital. Through the visioning of an approach that addresses these intersecting identities and our own experiences with racism, cisheterosexism, and transphobia, we propose a theoretical framework, Queer AZN and Pasifika Critical Race Theory (CRT), for clinical social work praxis. Specifically, we describe six tenets of a Queer AZN and Pasifika CRT approach, which include (1) …
On Localization Of Eigenfunctions Of The Magnetic Laplacian, Jeffrey S. Ovall, Hadrian Quan, Robyn Reid, Stefan Steinerberger
On Localization Of Eigenfunctions Of The Magnetic Laplacian, Jeffrey S. Ovall, Hadrian Quan, Robyn Reid, Stefan Steinerberger
Mathematics and Statistics Faculty Publications and Presentations
Let Ω ⊂ ℝd and consider the magnetic Laplace operator given by H(A) = (–i∇ – A(x))2, where A : Ω → ℝd, subject to Dirichlet boundary conditions. For certain vector fields A, this operator can have eigenfunctions, H(A)ψ = λψ, that are highly localized in a small region of Ω. The main goal of this paper is to show that if |ψ| assumes its maximum at x0 ∈ Ω, then A behaves 'almost' like a conservative vector field in a -neighborhood of x0 in a precise sense. In particular, we expect localization in regions where |curl A| is small. …

Bht-Qaoa: The Generalization Of Quantum Approximate Optimization Algorithm To Solve Arbitrary Boolean Problems As Hamiltonians, Ali Al-Bayaty, Marek Perkowski
Electrical and Computer Engineering Faculty Publications and Presentations
A new methodology is introduced to solve classical Boolean problems as Hamiltonians, using the quantum approximate optimization algorithm (QAOA). This methodology is termed the “Boolean-Hamiltonians Transform for QAOA” (BHT-QAOA). Because a great deal of research and studies are mainly focused on solving combinatorial optimization problems using QAOA, the BHTQAOA adds an additional capability to QAOA to find all optimized approximated solutions for Boolean problems, by transforming such problems from Boolean oracles (in different structures) into Phase oracles, and then into the Hamiltonians of QAOA. From such a transformation, we noticed that the total utilized numbers of qubits and quantum gates …

Mathematics and Statistics Faculty Publications and Presentations
There is extensive evidence that network structure (e.g., air transport, rivers, or roads) may significantly enhance the spread of epidemics into the surrounding geographical area. A new compartmental modeling framework is proposed which couples well-mixed (ODE in time) population centers at the vertices, 1D travel routes on the graph’s edges, and a 2D continuum containing the rest of the population to simulate how an infection spreads through a population. The edge equations are coupled to the vertex ODEs through junction conditions, while the domain equations are coupled to the edges through boundary conditions. A numerical method based on spatial finite …
Stalemate At Port Arthur: William James On War, Vulnerability, And Pluralist Personalism, Bennett Gilbert
Stalemate At Port Arthur: William James On War, Vulnerability, And Pluralist Personalism, Bennett Gilbert
History Faculty Publications and Presentations
Using a close reading of a single clause and its context in a section in A Pluralist Universe, we see the moral dangers James saw in traditional ontology, in particular its relation to war and peace. This analysis opens up James’s combining the personalist philosophy of his friend Borden Bowne (and others) with the pluralism he developed late in his career. This leads, further, to reflection of James’s performative philosophizing. Finding in James a theory of “pluralistic personalism” gives us a fresh look at the far-reaching power of his basic concepts of moral philosophy.

A Magical Symbiosis: The Advent Of Witchcraft In The Age Of Social Technology, James Dryden
A Magical Symbiosis: The Advent Of Witchcraft In The Age Of Social Technology, James Dryden
University Honors Theses
This paper investigates the relationship between social media and witchcraft practitioners in online communities. After providing a landscape of how other researchers have studied similar phenomenon, interviews with anonymous witches who utilize online platforms such as TikTok and Instagram were conducted by the author. Using these testimonies in conjunction with the research of others, the author identifies trends and similar stories between American witches regarding Wicca, the commodification of the craft, and how witchcraft practice continues in the modern day.

Individually, the COVID-19 and HIV pandemics have differentially impacted minoritized groups due to the role of social determinants of health (SDoH) in the U.S. Little is known how the collision of these two pandemics may have exacerbated adverse health outcomes. We evaluated county-level SDoH and associations with hospitalization after a COVID-19 diagnosis among people with (PWH) and without HIV (PWOH) by racial/ethnic groups. We used the U.S. National COVID Cohort Collaborative (January 2020-November 2023), a nationally-sampled electronic health record repository, to identify adults who were diagnosed with COVID-19 with HIV (n = 22,491) and without HIV (n = 2,220,660).

This paper reports the development and characterization of a novel ultra-wideband microwave absorber material (MAM) based on vertically aligned carbon fibers and ferrite beads. This specific material combination and manufacturing process allows MAM design that is thin, lightweight, and broadband. The material is prepared using a flocking process in which its components are electrostatically deposited on top of an adhesive substrate. Distinct material properties of the substrate and materials layers require characterization done with two separated layers. The microwave absorption characteristics are studied first by rectangular waveguide measurements at X and Ku bands that yield complex electric permittivity and magnetic …
