Covering The Care: Impacts Of Labor And Delivery Unit Closures On Maternal Health Outcomes, Bridget Green, Deborah Fournier, Susy Hawes

All Materials

In 2022, more than half of rural hospitals and one-third of urban hospitals in the United States lacked obstetric services, reflecting an escalating trend of hospital labor and delivery (L&D) unit closures across the US. Despite some large-scale studies reporting negligible impacts of L&D closures on maternal health, an analysis of the literature presents a clear net negative impact for vulnerable women, including those who identify as members of a racial or ethnic minority, those who have low-income, and those who are Medicaid members. For many families, the disappearance of local obstetric care is not merely an inconvenience but instead …

From Winans To Wallahee: Treaties, The Washington State Supreme Court, And The Pursuit Of A More Just Rule Of Law, Monte Mills Dec 2025

From Winans To Wallahee: Treaties, The Washington State Supreme Court, And The Pursuit Of A More Just Rule Of Law, Monte Mills

Washington Law Review

The relationship between the United States federal government, the states, and Native Nations has long been at the core of federal Indian law. From the earliest decades of its jurisprudence, for example, the United States Supreme Court struggled in its efforts to analyze and define the rights, authorities, and interactions of Native Nations within and in relation to the evolving structure of constitutional federalism. Treaties between the United States and Native Nations were central to those decisions and provided a necessary, constitutional check against state interests intent on eliminating sovereign Native Nations. Those constitutional and structural implications thus go well …


The Reasonability Rule For Medical Damages In Tort: In Defense Of Chargemaster Recovery, Avery E. Tunstill Dec 2025

The Reasonability Rule For Medical Damages In Tort: In Defense Of Chargemaster Recovery, Avery E. Tunstill

Washington Law Review

In a personal injury suit, Washington law requires the plaintiff to prove that their medical costs are reasonable to recover damages for those costs. Tort reform proponents attempt to use this reasonability rule to limit tort damages awards. They argue that a plaintiff should only recover a portion of a hospital’s bill because most people do not pay a hospital’s sticker price—or the “chargemaster rate”—for medical care. Some reformers argue that recovery rates should instead be based on a set figure. Others argue in favor of eliminating the collateral source rule, which prohibits juries from reducing tort damages awards in …

Institutional Isomorphism, Top Management Commitment, And Environmental Disclosure In Tanzania’S Construction Sector, Aulelius Lema, Siasa Issa Mzenzi Dec 2025

Institutional Isomorphism, Top Management Commitment, And Environmental Disclosure In Tanzania’S Construction Sector, Aulelius Lema, Siasa Issa Mzenzi

Business Management Review

This study examined the influence of institutional isomorphism on environmental disclosure (ED) in Tanzania’s construction sector and the mediating role of top management commitment (TMC). A cross-sectional design was employed, with data collected from 314 construction firms. Environmental disclosure was measured using content analysis of financial reports, and Structural Equation Modelling using the Maximum Likelihood Estimation (MLE) method was used to estimate the structural model. The findings reveal that coercive, normative, and mimetic pressures significantly impact ED.

Effect Of Digital Noise Reduction Processing On Subcortical Speech Encoding And Relationship To Behavioral Outcomes, Subong Kim, Mary Schroeder, Hari M. Bharadwaj Dec 2025

Effect Of Digital Noise Reduction Processing On Subcortical Speech Encoding And Relationship To Behavioral Outcomes, Subong Kim, Mary Schroeder, Hari M. Bharadwaj

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Perceptual benefits from digital noise reduction (NR) vary among individuals with different noise tolerance and sensitivity to distortions introduced in NR-processed speech; however, the physiological bases of the variance are understudied. Here, we developed objective measures of speech encoding in the ascending pathway as candidate measures of individual noise tolerance and sensitivity to NR-processed speech using the brainstem responses to speech syllable /da/. The speech-evoked brainstem response was found to be sensitive to the addition of noise and NR processing. The NR effects on the consonant and vowel portion of the responses were robustly quantified using response-to-response correlation metrics and …

An Analysis Of Neuroidal Memory Formation Within D. Melanogaster, Jerry Chang Dec 2025

An Analysis Of Neuroidal Memory Formation Within D. Melanogaster, Jerry Chang

Master's Theses

The Neuroidal model poses a neurobiologically plausible theory for modeling the brain. This symbolic network has been shown to capture realistic memorization behaviors using the JOIN algorithm. The model has also been recently improved by incorporating Watts-Strogatz small-worlds within its base structure. From the efforts of neuroscience researchers, we have access to the Drosophila melanogaster (D. melanogaster) fruit fly’s connectome, which has been found to also contain small-worlds in this thesis. By synthesizing the Ocellar Ganglion (OCG) region of Drosophila, we compare a digitized version of a real-world brain with an instance of the Neuroidal model. In this thesis, we …

Using Scenario-Based Design Activities To Explore Sociotechnical Thinking In Engineering Professionals, James M. Whealan Dec 2025

Using Scenario-Based Design Activities To Explore Sociotechnical Thinking In Engineering Professionals, James M. Whealan

Master's Theses

Sociotechnical thinking is the ability to recognize the interconnectedness of both technical and non-technical dimensions such as environmental, economic, social, cultural, and political factors. Although traditional engineering curriculum often emphasizes technical knowledge and skills, research suggests that engineering work is inherently sociotechnical. While sociotechnical thinking is a critical engineering skill, relatively little is understood about the nature of it or the different aspects comprised within it. To that end, this study addresses the following research question: What sociotechnical factors do engineering professionals consider in a collaborative scenario-based design activity? To answer this question, we conducted a qualitative study of engineering …
