Results show that the raids had negative consequences in …

Behind The ‘Lettuce Curtains:’ Rural Homelessness In The Salinas Valley, California, Allison Evans

Journal of Rural Social Sciences

Rural homelessness remains under-researched despite its prevalence outside the city. This research note presents preliminary findings from a case study in the Salinas Valley, California, examining how rurality—particularly its statistical definitions and socio-cultural conceptions—shapes homelessness policy formation, resource allocation, and local politics.

Racialized Internationalization And College Sport: Amplifying Black Ncaa Division I International College Athlete Voices Through Critical Podcasting, Timothy Ford Bryson

Journal of Comparative & International Higher Education

College sports in the United States have become a key site for internationalization in higher education, with international college athletes (ICAs) comprising 13% of Division I athletes (NCAA, 2023). While ICAs pursue degrees, compete at elite levels, and navigate F-1 visa requirements, their experiences remain underexamined in international education scholarship. This omission is especially stark for Black ICAs, whose stories are often collapsed into either generalized international student scholarship or studies of Black U.S. athletes.

This dissertation addresses this gap by examining the experiences of Black NCAA Division I ICAs through the lens of Migration Infrastructure Theory and Black Diasporic …

The Degradation Of Prices: Platform Power, The Erosion Of Price Comparison, And Rebuilding Comparison Shopping In The Digital Economy, Stephanie T. Nguyen, Shaoul Sussman

Center for Law and the Economy

The ability to know the price of a product or service and then compare prices of similar products or services is a foundational cornerstone of consumer choice and competitive markets. Once, buyers could more easily compare identical products across multiple sellers. However, this process has systematically degraded over time and has become increasingly difficult to do in practice. When prices are a reliable signal of product and market value, consumers can make informed purchasing decisions and sellers can compete for business by offering more attractive prices to consumers. This is a core market force that keeps price levels in check …

A Reproducible Hdr-Native Psychophysics Infrastructure For Color Science Research, Fernando Voltolini De Azambuja

Theses

Color science psychophysics measures the human visual system by relating controlled visual stimuli to observer responses, often through forced-choice paradigms such as two-alternative forced choice (2AFC) (Kingdom and Prins 2016). These studies require stimuli specified in physically meaningful units, technically correct display emission, and reproducible execution (Fairchild 2013; Lin et al. 2023). In practice, graduate-level experiments often rely on bespoke MATLAB or Python scripts, standard dynamic range (SDR)-first toolchains such as Psychtoolbox and PsychoPy, manual stimulus duplication, and incomplete capture of calibration, colorimetric state, and display capability (Brainard 1997; Peirce et al. 2019). These limitations increase experimental friction and create …

Multiplexed Fabry-Pérot High-Temperature Sensing Based On Dispersive Microwave-Photonic Frequency-Time Domain Analysis, Ruimin Jie, Chen Zhu, Bohong Zhang, Koustav Dey, Jie Huang

Electrical and Computer Engineering Faculty Research & Creative Works

We propose and experimentally demonstrate a multiplexed high-temperature Fabry-Pérot (FP) fiber sensing system interrogated by dispersive microwave-photonic frequency-time domain analysis (DM-FTDA). In the proposed architecture, incoherent broadband probing light is modulated by radio-frequency (RF) signals and then reflected by a parallel network of hollow-core photonic crystal fiber FP (HCPCF-FP) sensors. A chirped fiber Bragg grating provides strong dispersion to map the composite FP spectral response into a well-defined microwave transfer function. Unlike conventional optical Fourier-domain multiplexing that requires deliberate cavity-length allocation, the proposed approach achieves multiplexing via delay-dominated discrimination. Distinct delay fibers are assigned to each sensor branch, and an …

Redesign And Flow Characterization Of Microcapsules Through Hollow 3d-Printed Microneedles, Ryan Lang

Bioengineering Master's Theses

Traditional bulk cavity microneedles suffer from stagnant zones and internal wall collisions that damage suspended cell carriers. This research computationally optimized and experimentally validated a novel multi-planar, branched hollow microneedle chamber to minimize dead volume and protect sensitive payloads. By replacing the traditional bulk cavity with a symmetric six-peripheral nozzle architecture, COMSOL simulations confirmed the elimination of central stagnation zones. Low fluid velocities (0.05 m/s) maintained streamline alignment, while higher velocities (0.32 m/s) induced wall impacts, a drift completely mitigated by high-viscosity fluids.

Arrays fabricated via SLA 3D printing demonstrated consistent cross-unit nozzle diameters, despite a 27.8% average print shrinkage. …

Rooted In Hillsboro: An Urban Tree Protection Project, Leandre Mills, Aidan Mcclinton, Aria Shopbell, Karl Coppock, Wally Mcallister

Master of Urban and Regional Planning Workshop Projects

The Canopi team and the City of Hillsboro Urban Forestry Program completed this project to evaluate and strengthen municipal tree protection policies. Current regulations rely heavily on tree replacement rather than retention, contributing to loss of mature canopy and reduced climate, infrastructure, and equity benefits. In many cases, mature trees removed during development or infrastructure projects are replaced with small-caliper plantings that do not provide equivalent environmental or community value for decades.

As Hillsboro grows, the city faces increasing climate pressures, including urban heat island effects, stormwater impacts, invasive pests, and uneven canopy distribution across historically underserved neighborhoods. These challenges …
