Confronting Inequality: Three Eras Of Gender And Tax Scholarship, Bridget J. Crawford

Loyola of Los Angeles Law Review

Tax law is not neutral—it encodes social values and reinforces certain longstanding hierarchies. For over fifty years, legal scholarship at the intersection of gender and tax has exposed how seemingly neutral tax laws perpetuate gender inequality. This Article uses the metaphor of quilting to trace the evolution of this scholarly field across three distinct eras.

Part I names and defines the designing era (1971–1986), which began with Grace Blumberg’s writing on the gendered impact of tax laws on marriage, labor, and caregiving; she framed taxation as a tool of social control over women. Blumberg’s work laid the foundation for other …

The Lion's Share: The Secret Land Grab Of Drake's Circumnavigation, Melissa Cole Darby

Anthropology Faculty Publications and Presentations

Francis Drake’s journey around the world between 1577 and 1580 is renowned as one of the most famous voyages in history. The circumnavigation was a great achievement for England, but the official story Queen Elizabeth and her Privy Council maintained for nine years was that Drake was a pirate, and that the treasure he captured on the voyage would be returned to Spain. Upon his return, information about the voyage and his route were suppressed and the crew was sworn to secrecy: they were not to reveal where they travelled on ‘pain of death’. Here I present the case that …

Electron And Hole Surface Roughness Scattering-Limited Mobilities In Oxygen-Inserted (Oi) Si Channel, Vikram Magendar, Yi Ann Chen, Albert Lu, Donghun Kang, Daniel Connelly, Marek Hytha, Hideki Takeuchi, Robert Mears, Hiu Yung Wong

Faculty Research, Scholarly, and Creative Activity

The electron and hole surface roughness scattering (SRS)-limited mobilities, deconvolved from 4.2 K measurements, were compared between oxygen-inserted (OI) and control Si channel for n- and pMOSFETs. It was found that electron SRS-limited mobility in the OI-Si channel is 55% higher, whereas hole SRS-limited mobility is comparable to the control. To elucidate the difference, the Si/Si O2 interface roughness and the nanoscale thickness variation of the gate oxide were analyzed in detail, via high-resolution transmission electron microscopy images, and fed into numerical calculation of the SRS-limited mobility. The power spectral densities (PSDs) based on the Yule–Walker autoregressive model revealed that …

Vigor: Virtual Intelligence For Gaze Observation And Representation, Meherun Nesa Shraboni

Theses and Dissertations

Eye tracking in modern XR head-mounted displays can capture high-frequency gaze data at 90–120 Hz, generating thousands of samples within a single 30-second interaction. At the same time, the XR market has grown to millions of active users worldwide, with major platforms such as Meta investing heavily in eye-tracking-enabled devices. Despite this large-scale adoption and data availability, most applications still rely on hand-controller input, with gaze either processed offline or reduced to a simple pointing signal. As a result, the majority of temporally rich gaze information remains unused in real-time interaction, limiting system responsiveness, reducing interaction fidelity, and preventing effective …
