Rethinking Teacher Education Programs: (Mis)Understanding Of Culturally Responsive Teaching Among Teacher Candidates, Shirley M. Sommers

Northwest Journal of Teacher Education

This article draws from a study conducted on pre-service teachers enrolled in a teacher education program. The study examines students’ understanding and misunderstanding of what constitutes culturally responsive teaching. This is a mixed methods study. A Likert-type survey and qualitative questionnaires were used to collect data. Descriptive statistics were used to analyze survey data, and a thematic coding method was used for analysis of qualitative data. The results of the study show that pre-service teachers are aware and knowledgeable of the term culturally responsive teaching as the term is widely used in the teacher education program in which they were …

“The first municipal water filter of the rapid sand type was built at Somerville, NJ, and thus began its wonderful history.”  By 1917 the rapid sand filter was the standard defense against typhoid epidemics in the United States.

Lessons From The Club Homeschool Capstone: Testing, Data Discipline, And The Computer Science Curriculum, Shane Brown

University Honors Theses

This thesis looks at the CLUB Homeschool Capstone project to argue that Portland State University's Computer Science curriculum should introduce testing and data quality discipline earlier and more intentionally than it does now. As team lead of a seven-person team, I coordinated sprint planning, communicated with the sponsor, and developed custom Discourse plugins that enhanced an existing forum platform instead of creating a separate application database, as requested by the sponsor. The project's requirements document called for a formal testing plan, but our team lacked the practical experience to implement one. This gap became evident through my internships as a …

Survival First: How Citizens Prioritize Competing Climate-Health Risk Countermeasures Under Fiscal Constraints, Katsuya Tanaka, Kazuhide Akaishi

Center for Public Service Publications and Reports

When governments must allocate limited resources among competing climate-health countermeasures, citizen risk priorities determine political feasibility—yet whether those priorities translate into fiscal support remains poorly understood. This study develops a hybrid best–worst scaling and contingent valuation framework that integrates individual-level priority parameters into an acceptance model, enabling direct testing of whether preference intensity predicts willingness to pay. Applied to a largesample survey of residents in Yokohama, Japan—a rapidly aging metropolis facing escalating heat emergencies—the analysis reveals three findings. First, citizens exhibit a survival-first hierarchy, decisively prioritizing immediate protective measures over long-term structural interventions, with consensus varying sharply across countermeasure types. …

Oak Savanna Expansion: Indigenizing Psu's Urban Landscape, Ash Herb

University Honors Theses

Since time immemorial Indigenous Peoples have resided in what is now named Portland of the Pacific Northwest in the Willamette Valley. For hundreds of years, this forested Land has been colonized, razed to stumps and covered in cement in order to build the urban landscape. Due to such destruction on a broad scale, we are experiencing the results of climate catastrophe. By finding ways to reclaim our relationship with Land and returning to Indigenous epistemologies, our urban landscape has the opportunity to shift towards restoration and prosperity. Indigenous plants have existed here, supporting humans in a reciprocal relationship, for thousands …

Spatial Structure And Energy Content Of Wakes Behind Single And Arrayed Undulated Cylinders, Taiga Naomi Drucker-Boisvert, OndˇRej FerˇCák, Jérémie Auzoux, Sarah E. Smith, Zein Sadek, Rowan Moore, Christain T. Murphy, Trevor Dunt, Jennifer A. Franck, Raul Bayoan Cal

Biologically inspired undulated cylinder geometries significantly influence wake structure and vortex-induced vibrations in turbulent flows, yet the underlying mechanisms are not fully understood. It is further unknown how these influences extend to multi-cylinder arrays, where interacting wakes accumulate and mix. This study examines the wake characteristics of an undulated cylinder and a smooth elliptic cylinder in single- and multi-cylinder array configurations, using particle image velocimetry and proper orthogonal decomposition (POD). Relative to the smooth elliptic cylinder, the undulated geometry induces pronounced spanwise-axial variability, characterized by enhanced near-wake mean momentum and weak far-wake signatures, consistent with reduced turbulent kinetic energy. While …

Of Cables And Threads: Reweaving The Urban Fabric At The Edge Of Bogotá, Federico Pérez Fernández

University Honors College Faculty Publication and Presentations

Over the past two decades, gondola lifts have become central to interventions in urbanLatin America’s auto-constructed peripheries. As cable car urbanism reshapes the city’sedge, it raises fundamental questions about the notion of the “urban fabric” as a socio-material practice, an epistemology, and a site of politics. In Bogotá, the city’s first aerialcable car line has been integrated into the sprawling district of Ciudad Bolívar, revealinga dialectical process of urban fabrication—a form of urban weaving, in the language ofboth experts and residents, that bridges technical retrofits and popular logistics. Thesestate-community interfaces operate beyond the binaries of compromise and dissent, co-optation and …

Identity, Needs, And Conflict Online: Understanding Cultural Fragmentation In The Black Diaspora, Imhile Omosede Dora Akpata

Dissertations and Theses

This study examines how identity formation, intra-diaspora tensions, and social media interactions contribute to fragmentation within the Black diaspora. While existing scholarship, including work by Godfried Asante and Elizabeth Chacoko has emphasized the fluid and socially constructed nature of Black identity, less attention has been given to how these processes operate in practice across diverse diasporic groups and how they are intensified in digital environments. This research addresses this gap by analyzing how individuals negotiate Black identity, how tensions emerge within the diaspora, and how social media shapes and amplifies these dynamics.

Drawing on Social Identity Theory developed by Henri …

Improving The Fpga Radio Design Cycle: Implementing Dvb-S2 Modulation Using Verilator And Gnu Radio, Seth Pellegrino

Dissertations and Theses

In embedded digital radio systems, a central challenge is meeting the real-time throughput required to process the samples--especially for space-bound ultra-wideband SDRs which must handle more than 100 Gbps entirely onboard. An FPGA's programmable logic offers sufficient potential, but realizing a particular radio flow is a project usually fraught with defects and long turnaround times. We simulated Verilog modules in a custom harness that adapted a Verilated model to GNU Radio, which allowed for breaking down a complicated radio flow (here, DVB-S2 modulation) into a series of well-bounded problems each with clear criteria for success. The framework, built on open …

Editorial: Participatory And Just Governance: Empowering Local And Indigenous Communities, Melissa Haeffner, Maiko Sakamoto, Jenia Mukherjee, Hong Quan Nguyen, Soyo Takahashi

Environmental Science and Management Faculty Publications and Presentations

The papers in this Research Topic (RT) extend insights on the roles of social relations, institutional arrangements, Indigenous ways of knowing, local knowledge, and decisionmaking participation in shaping water governance and practice. Despite efforts to predict flows and possible hazards, we continue to observe “unintended consequences” when humans interact with waterscapes. What we often learn, we argue, is that what appears “unintended” often reflects a deliberate architecture of exclusion; one that becomes legible only when social power relations are placed at the center of analysis alongside hydrological variables. Doing so may illuminate where injustice complicates intentions and what difference participatory …

Ƒ(Enlightenment): A Complex Adaptive Systems Model Of Recursive Causality And Human Meaning-Making, Daniel Lambert

Dissertations and Theses

Conflict Resolution has developed as a richly interdisciplinary field; however, its theoretical architecture remains fragmented across distinct bodies of scholarship. Existing approaches offer valuable but often isolated explanations of conflict behavior, limiting their ability to account for its complexity. This thesis addresses this limitation by advancing systems science as an organizing framework for integrating these perspectives. It introduces the Human-Complex Adaptive Systems (H-CAS) framework, which conceptualizes human behavior as a recursive adaptive process operating across interconnected regulatory domains. Within this model, conflict is not treated as a discrete event or purely deliberative process, but as an emergent property arising from …

Trust And Signaling: An Exploratory Study Of Residential Attitudes Towards Energy Efficiency Advisors And Outdoor Media, Hal T. Nelson, Ivana Osmanovic

Public Administration Faculty Publications and Presentations

As the building sector shifts toward community-led energy efficiency (EE) initiatives to mitigate the climate crisis, scaling adoption requires understanding behavioral drivers. This study examines key drivers of EE measure adoption: perceived non-energy benefits, trusted advisors, and behavioral signaling. This research contributes to the energy policy and social science literature by empirically linking social trust with signaling preferences. It extends existing EE adoption decision theories by identifying distinct clusters of “expert” versus “close” advisors across demographic groups. Data from an experimental survey (n = 238) in Portland, Oregon, were analyzed using principal component analysis (PCA) and multivariate regression modeling. Results …

Slovenian-Assisted Slate Integrated Infrastructure Development Project (Siidp) And Solid-Waste-Management System, Musa Zakari

Hatfield Graduate Journal of Public Affairs

The study was assessed the Slovenian Assisted Slate Integrated Infrastructure Development Project (SIIDP) on its ability to transform the solid-waste-management system. Yet, in a bid to tackle the intractable waste problem in Nigeria, It emphasized the need to have sustainable policy structures, creative infrastructural and technical cross-border cooperation. The research employed a mixed-method design, which included documentary analysis and a survey. Quantitative data were analyzed using multiple linear regression analysis (SPSS version 27), while qualitative insights were analyzed thematically. Their regression analysis found that technology transfer (B = 0.284, p = 0.000), capacity building (B = 0.256, p = 0.001), …

From Policy To Practice: Analyzing Inclusive Education Strategies In Nigerian Internally Displaced Persons (Idps) Camps, Chukwuyem Joel Arimie, Williams Okotie Dr

Hatfield Graduate Journal of Public Affairs

Through high-quality education delivery, inclusive education indicates the pursuit of social justice for all marginalized societies. The study examines how the Edo camp's internally displaced people are impacted by inclusive education policies. Relevant policy and regulatory frameworks pertaining to inclusive education in Nigeria were examined in the research. Because the Hope for the Needy Foundation provides for the educational needs of the children in the camp, interview responses suggest that despite the policy frameworks, strategies for the effective execution of the policy in the IDP camp have not yet been put in place. The article makes the case that the …

The Growing Needs For Young Adults’ Behavioral Health Services In Oregon And Pathways For Sustainable Service Deliveries, Anis Zaman

Hatfield Graduate Journal of Public Affairs

Recent OHA data indicate a significant surge in behavioral health cases among young adults ages 17-26 across Oregon. Every year in Oregon, the total number of young adults receiving medical treatment includes a significant number of them who have behavioral health challenges. This large group of young adults with mental health conditions is vulnerable to suicidal ideation and substance overdose. Despite sincere efforts by the Oregon Health Authority (OHA), the young adult mental health state of Oregon remains a concern. Therefore, there is a need for a comprehensive action plan for the sustainable delivery of mental health services to young …

Detecting And Correcting Systematic Image Distortion In Digital Atomic-Resolution Images From Crystals: Projected Symmetry Of Graphite Calibration Samples For Scanning Prove Microscopy And Subperiodic Crystals For Aberration-Corrected Transmission Electron Microscopy, Tyler Michael Bortel

Dissertations and Theses

Though it is an impressive technology, Scanning Tunneling Microscopy (STM) produces images commonly plagued by small systematic errors, often called "drift". These effects have a variety of causes, most notably nonlinear behavior of piezoelectric actuator tubes responsible for the positioning of the scanning probe or sample. One result of these distortions is a potential incorrect classification of the symmetry groups and projected Laue classes of recorded images from crystals—made possible by using recently developed objective methods. An implementation of a known method for detecting and correcting these errors is presented. This method operates strictly in Fourier space so as to …

Understanding The Role Of Entropy In Designing High-Performance Thermoelectrics, Subrata Ghosh, Soongyu Kwon, Wenjie Li, Dipika Mandal, Amin Nozariasbmarz, Marcia Ahn, Sumanta K. Karan, Allison M. Beese, Yi Xia, Shashank Priya, Bed Poudel

Mechanical and Materials Engineering Faculty Publications and Presentations

The design of high-entropy alloys is effective in lowering thermal conductivity but often reduces carrier mobility, thereby limiting electrical transport properties. Understanding the relationship among configurational entropy, thermal conductivity, and carrier mobility in high-entropy alloys is critical for enhancing thermoelectric performance. We demonstrate that a systematic and substantial increase in configurational entropy in half-Heusler alloys leads to an asymptotic reduction of lattice thermal conductivity. The reduced phonon group velocity and enhanced phonon scattering induced by atomic-scale chemical disorder result in a low lattice thermal conductivity of 2 watts per meter per kelvin at room temperature, with an achievable minimum of …

Block Kinematics, Interseismic Coupling And Fault Slip Rates In The Aegean Region From Gps And Earthquake Slip Vector Data: 1. Upper Plate Structures, Konstantinos Chousianitis, Sotiris Sboras, Volkan Özbey, Robert Mccaffrey, Semih Ergintav

Geology Faculty Publications and Presentations

We represent the active deformation of the Aegean region with an elastic‐kinematic block model composed of a finite number of rotating crustal blocks whose boundaries coincide with major active structures. A total of 832 GPS velocities and 146 earthquake slip vectors were inverted to provide estimates of block rotations and interseismic locking on block‐bounding faults so as to best reproduce the observed deformation field. Our regional model allowed us to derive a self‐consistent set of geodetic slip rates for upper plate faults and the Hellenic subduction system, the results of which are presented in a companion paper, and to determine …

Seabed Wide-Angle Reflection Coefficient And Source Radiation Pattern Measurements From A Low-Frequency Multibeam Sonar, Charles W. Holland, Cody R. Henderson, Tim Sonnemann, Bjørnar Langli, Daniel L. Orange

Electrical and Computer Engineering Faculty Publications and Presentations

In acoustic remote sensing, the seabed frequency-domain reflection coefficient contains significant geoacoustic information, namely the depth and frequency dependence of sediment sound speed, density, and attenuation. Typical reflection measurements are performed with a towed source and/or receivers to obtain a range of seabed reflected angles. It is shown here that the measurements can be performed using a hull-mounted low-frequency multibeam sonar with an offboard fixed or drifting hydrophone. To obtain the reflection coefficient (as well as scattering strength and other quantities of potential interest), the multibeam sonar radiation pattern must be known. Radiation patterns and absolute levels of the Kongsberg …
