Nature-Based Solutions For Urban Stormwater Management, Nima Zafarmomen, Vidya Samadi, Susan Lunt

Forestry and Natural Resources

This paper explores Nature-based Solutions (NbS) for urban stormwater management, emphasizing their role in mitigating runoff, reducing flood risks, and improving water quality. Bioretention systems (BRS), green roofs, permeable pavements, and vegetated swales utilize natural processes such as infiltration, evapotranspiration, and filtration to manage stormwater while promoting urban resilience and supporting biodiversity effectively. The performance of these solutions depends on vegetation, soil, and climatic parameters, highlighting the need for context-specific design and implementation. While NbS present sustainable alternatives to conventional infrastructure, technical, economic, social, and institutional challenges require interdisciplinary collaboration and supportive policies to unlock their full potential.

Treaty Justice: Charles Wilkinson's Homage To The Boldt Decision, Michael C. Blumm

Public Land & Resources Law Review

Charles Wilkinson, a beloved teacher, author, and advisor, gave his readers perhaps his most personal gift in Treaty Justice: The Northwest Tribes, the Boldt Decision, and the Recognition of Fishing Rights (U. Washington Press, 2024). Wilkinson finished the manuscript just a week before his unexpected death, at age 81, in 2023. The book is a blend of personal memoirs of countless encounters of people involved in the seminal Boldt decision–which revolutionized treaty fishing rights– and its aftermath, and part of legal history by an analyst who was acutely sensitive to the vagaries of both law and history. We are fortunate …

When Words Fail: Why Ai-Driven Context Beats Word Error Rate For Safety-Critical Air Traffic Control, Muhammad Maaz

Theses and Dissertations

Accurate speech-to-text transcription is critical for Air Traffic Control (ATC) to en- sure safety and operational efficiency. However, existing Automatic Speech Recognition (ASR) systems struggle with domain-specific phraseology, high noise levels, and real-time constraints. This work explores domain adaptation strategies of OpenAI’s Whisper ASR model, applying Transfer Learning and Low-Rank Adaptation (LoRA) on ATC benchmark and a Federal Aviation Administration (FAA) corpus. Experimental results show that fine- tuning significantly reduces Word Error Rate (WER) from 55.2% to 6.8%, yet WER alone fails to capture safety-critical transcription errors. To address WER’s limitations, we introduce the Contextual Error Rate (CER), a novel …

Sex-Dependent Modulation Of Behavioral Allocation Via Ventral Tegmental Area-Nucleus Accumbens Shell Circuitry, Kristen A. Mclaurin, Jessica M. Illenberger, Hailong Li, Rosemarie M. Booze, Charles F. Mactutus

Faculty Publications

Diagnostic criteria for substance use disorder, cocaine type (i.e., cocaine use disorder), outlined in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders, imply that the disorder arises, at least in part, from the maladaptive allocation of behavior to drug use. To date, however, the neural circuits involved in the allocation of behavior have not been systematically evaluated. Herein, a chemogenetics approach (i.e., designer receptors exclusively activated by designer drugs (DREADDs)) was utilized in combination with a concurrent choice self-administration experimental paradigm to evaluate the role of the mesolimbic neurocircuit in the allocation of behavior. Pharmacological activation …
