Assessing Cognitive Abilities In Students With Hearing Loss And Specific Learning Disabilities, Pooja Gupta, Corinna V. Cole, William H. Blackwell

Journal of Human Services: Training, Research, and Practice

This literature review synthesizes approximately 30 years of research on students from kindergarten through 12th grade with hearing impairments who are suspected of having a specific learning disability (SLD). Assessing SLDs in these students presents significant challenges, particularly when evaluating cognitive abilities using the Cattell-Horn-Carroll (CHC) theory of intelligence. This theory encompasses seven broad cognitive domains that influence academic success in reading, mathematics, and writing, including crystallized intelligence, fluid and sequential reasoning, long-term and short-term memory, visual processing, auditory processing, and processing speed. Since auditory processing is inherently affected in students with hearing impairments, this review excludes it from discussion. …

“That’S Not My Name”: The Linguistic Violence Of Misnaming Parties In Court Proceedings, Robert S. Chang, Cecily C. Hazelrigg, Linda Cj Lee

Washington Law Review

This Article calls attention to the harms done when parties are misnamed in legal proceedings. Misnaming, which many might initially consider trivial, is properly understood as a form of linguistic violence that can inflict dignitary harms as well as have material consequences. Misnaming takes on a different valence when it is done by the state. This Article focuses on the misnaming of Indigenous, Asian, and Latine people, beginning first with the way misnaming is done by the administrative state. The authors then discuss misnaming as it has operated in legal proceedings, providing both historical and contemporary examples from federal and …

High Torque Density Dual-Stator Vernier Motors With Flux Concentrating Rotors, Esmaeil Mohammadi, Ali Mohammadi, Mohammad Amin Jalali Kondelaji, Pedram Asef, Ion G. Boldea, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

Axial Flux Permanent Magnet (AFPM) machines are increasingly being studied for low-speed, direct-drive applications due to their compact structure and high torque output.

Civil and Environmental Engineering Faculty Publications and Presentations

The Menkaure Pyramid is the smallest of the three main pyramids on the Giza Plateau. Recently, the possibility of a second entrance to the Pyramid has been hypothesized by Van den Hoven [1], based on similarities between the polished granite blocks covering the Eastern face and the blocks around the main entrance on the Northern face. To test this hypothesis, measurement campaigns using three non-destructive techniques, Electrical Resistivity Tomography (ERT), Ground Penetrating Radar (GPR), and Ultrasonic Testing (UST), were carried out on the Eastern face of Menkaure Pyramid. ERT data was obtained from measurements of four long parallel profiles using …

Conditioning Elections: The Instability With Dynamic Voters, Lorenzo Collier

Political Science Student Papers and Posters

The stability of electoral outcomes is a cornerstone of democratic legitimacy, yet real-world elections increasingly exhibit volatility driven by dynamic voter populations and shifting preferences. By treating elections as a function f(x) where x represents voter choice, we can study the conditioning of election outcome functions under perturbations, analogous to sensitivity analysis of numerical solvers. This paper investigates the mechanisms underlying instability in elections when voters and their beliefs evolve over time, focusing on the effects of conditioning decisions on anticipated future changes. By surveying classical and contemporary models of voting rules under dynamic settings, this paper demonstrates how seemingly …
