The Testimonial Double Bind For Disabled People, Avram Hiller

Philosophy Faculty Publications and Presentations

Disabled people face a testimonial double bind: Either (1) they give entirely positive testimony about their disability, which may not be believed, or (2) they give some negative testimony about their disability, which either (2a) may not be believed, (2b) will risk reinforcing false and harmful stereotypes, or (2c) will risk damaging disability rights. While (1) has been discussed to a significant extent in the literature, (2) has been discussed to a much lesser extent, and a goal of this paper is to explore (2) in more detail. I further argue that this testimonial double bind may cause problems for …

Veterinary Drug Residue Regulations In Major U.S. Export Markets, Elliott James Dennis, Akinbode Okunola

Cornhusker Economics

Trade agreements shape the global agricultural trade landscape, encompassing both tariff and non-tariff measures. Among the latter, sanitary and phytosanitary (SPS) measures such as maximum residue limits (MRLs) are gaining attention. As trade tensions escalate, there is growing concern that countries could use SPS measures as a tool of retaliation in international agricultural markets, as they are often a focal point in trade negotiations (Disdier and Marette, 2010; Disdier and van Tongeren 2010; Grant et al., 2015).

Stolen Humanity On Display: Lacking Legislation For Human Remains In U.S. Museums, Sarah M. Fassio

Washington Journal of Law, Technology & Arts

In museums across the United States, displays of human remains are not rarities. Yet few attendees stop to consider the provenance behind those once-living parts of our ancestors. To do so, one would have to contend with an unpleasant history rife with scientific racism and graverobbing for the personal collections of society’s upper crust. Considering the origins of such displays reveals that the labels and names attached to human remains in museums often serve more to alienate them from their humanity than they do to connect or contextualize.

Legal regulations pertaining to displayed human remains are piecemeal. There are federal …

Precise Operations, Imprecise Laws: How Nebulous Laws Wreak Havoc In Outer Space, Matthew H. Ormsbee, Harine Raaj

Washington Journal of Law, Technology & Arts

As space operations advance with unprecedented precision, the laws governing these activities remain outdated, vague, and incapable of addressing contemporary challenges. The Outer Space Treaty (OST) and the Liability Convention, drafted in the Cold War era, fail to adequately define fundamental terms such as damage, fault, and compensation. This lack of legal precision creates significant liability gaps, particularly as space debris, mega-constellations, and private-sector actors reshape the space landscape. This article explores how these ambiguities hinder legal predictability and fair compensation for victims of space-related harm. By analyzing real-world space incidents, including the Cosmos 954 reentry, the Iridium-Cosmos collision, and …

Tailoring The Law: Protecting Fashion In The Future, Imaad Huda

False Starts & Finish Lines: Youth Sports, Coaching, & The Crisis Of The American Dream, John S. Lammert Jr

Master's Theses

False Starts & Finish Lines: Youth Sports, Coaching, & the Crisis of the American Dream examines how the American youth sports system reflects, reproduces, and at times resists the evolving contradictions of the American Dream. Drawing on a comparative analysis of institutional documents from public high schools, travel clubs, and recreational leagues, this thesis interrogates how youth sports have shifted from inclusive spaces of play and character-building to stratified marketplaces governed by the Athletic Industrial Complex (AIC). It argues that rising costs, performance pressures, and privatized structures have transformed access to sport—and, by extension, to the Dream itself—into a function …

Impacts Of Artificial Habitat Structures On Overwinter Fish Survival And Fish Presence In South-Central Nebraska, Logan Dietrich

Biology Theses, Dissertations, and Student Creative Activity

Artificial lentic systems, such as borrow pits, often lack structural complexity due to construction practices and steep bathymetry, limiting features like vegetation and woody debris essential for fish communities. To address this, artificial structures made of materials such as polyvinyl chloride are increasingly used by state and federal agencies to supplement habitat. However, little information is known about the impact these structures have on fish communities. Thus, the objectives of this study were to examine the influence of Georgia cubes in borrow pit impoundments on overwinter survival of sub-stock and ≥ stock Bluegill (Lepomis macrochirus) and Largemouth Bass …

Towards The Wearable Cardiorespiratory Sensors For Aerospace Applications, Chandan Sheikder

Journal of Aviation/Aerospace Education & Research

In safety-critical aviation operations, adaptive Human-Machine Interfaces (HMI) rely on accurate physiological monitoring to mitigate cognitive overload. While cardiorespiratory sensors are promising for real-time cognitive workload assessment, existing studies lack rigorous validation of consumer-grade devices in high-stress aviation contexts and fail to address measurement uncertainty propagation. This study evaluates the Zephyr BioHarness, a commercial wearable sensor, against clinical-grade equipment during arithmetic tasks simulating aviation cognitive demands. By integrating a neuro-fuzzy system with uncertainty propagation methods, we quantify the reliability of heart rate (HR) and breathing rate (BR) metrics for workload estimation. Results demonstrate moderate HR accuracy (RMSE: 4.85 bpm, CC: …

Empowering Precision Forecasting: Self-Supervised Lstm For Hourly Pressure And Temperature Prediction, Anand Shankar, Deepak K. Singh, Mantosh Kumar, Pankaj Kumar, Pradhan Parth Sarthi

Journal of Aviation/Aerospace Education & Research

The most important parts of any flight are landing and takeoff, and an aircraft's takeoff configuration must balance the regulated takeoff weight, runway length, and weather conditions to ensure a safe departure and arrival. In addition to runway length, wind, temperature, pressure, and visibility determine the total allowed takeoff weight and the economic viability of any trip. Thus, any meteorological office involved in flight planning and operation at any airport must accurately assess these factors, known as takeoff data. This research paper suggests multivariate self-supervised LSTM-based models to accurately predict the temperature and pressure (MSLP) of the takeoff data. The …
