Oregon’S History Of Using The Law To “Stack The Deck” In Favor Of White Males, Janet Steverson

Lewis & Clark Law Review

The United States has a sordid, racist history that permeates society still today. The State of Oregon has its own racist history, systematically excluding persons of Black African ancestry in its early years. This Essay explains this history and how seemingly historical practices continue to provide advantages to some, while detrimentally impacting others. This history is put in context by providing explanations of particular terms and this Essay further explains why examining these historical laws are critical in moving forward.

Digitization Of The Switching Stroop Task, Keagan Duster, Delia Mozqueda-Fuhrmeister, Kesten Anderson, Molly Conway, John Piaszynski, Aaron Winder, Conor Courtney, Kanchna Ramchandran

Modern Psychological Studies

The Switching Stroop (SS) task is a modification of the neuropsychological assessment, the Color Word Interference (CWI) task, which measures inhibition of pre-potent response. Both tests measure the ability to select and match appropriate responses to a cued dimension (instruction) of a stimulus. However, the SS additionally incorporates the ability to adapt to consecutive conflicting stimuli (the construct of dynamic adjustments of control). By integrating with existing commercial software for administering remote neuropsychological tests, we were able to digitize a previously published version of the SS, enhancing user friendliness and functionality. This electronic version of the SS provides a plethora …

Astrocytes play essential roles in the brain, and their dysfunction is associated with nearly every form of neurological disease. Despite their ubiquity, knowledge of how astrocytes contribute to disease pathogenesis is incomplete; accordingly, harnessing their biology toward therapeutics remains a major challenge. Here we show that the transcription factor Sox9 plays a context-specific role in maintaining astrocyte function and circuit activity in the aging hippocampus and Alzheimer's disease (AD) models. We found that Sox9 overexpression in astrocytes in AD models clears existing amyloid beta (Aβ) plaques and preserves cognitive function. Mechanistically, Sox9 promotes the phagocytosis of Aβ plaques by astrocytes …

Facts, Policy, And Discretion, F. Andrew Hessick, Carissa Byrne Hessick

Faculty Publications

Presidents, prosecutors, and judges often announce policies on how they will make discretionary decisions. These policies have met the criticism that discretion must be the product of an assessment of the particular facts of a case. Decisionmakers cannot base discretionary decisions on policy considerations, nor can they adopt policies stating how they intend to exercise their discretion. To do so, the argument goes, does not constitute an exercise of discretion, but rather an abdication of it.

This Article argues that this criticism misunderstands discretion. Discretionary decisions must rest on reasons, and reasons necessarily appeal to principles and policies that are …

Introduction: A-fib occurs when the electrical signals in the heart become unorganized and unsynchronized, resulting in an irregularly irregular heart rate. This can increase the risk of blood clots and stroke. The purpose of this paper is to explore two of the most common treatment options, comparing the efficacy of catheter ablation to AAD (antiarrhythmic drug) therapy in adults diagnosed with atrial fibrillation.

Methods: PubMed was searched using the keywords “atrial fibrillation,” “catheter ablation,” and “antiarrhythmic.” Operators and filters yielded a final result of 159 articles; four articles that most closely aligned with the focus of this research were reviewed. …

Open Contacts Adjacent To Posterior Dental Implants: Current Understanding And Emerging Preventive Concepts, Chiun-Lin Steven Liu, Shih-Cheng Wen, Ching-Jung Chang Chien, Je-Kang Du

Journal of Dental Sciences

Open proximal contacts between posterior dental implant restorations and adjacent natural teeth are a common yet underappreciated complication. This review examines the multifactorial etiology of open contact formation, including biomechanical discrepancies, prosthetic and surgical factors, occlusal force dynamics, and natural tooth migration. The clinical consequences-ranging from food impaction and gingival inflammation to proximal bone loss and diminished patient satisfaction-are also analyzed. These complications not only affected oral hygiene and comfort but might also contribute to peri-implant tissue breakdown and increased maintenance needs. Existing preventive and corrective strategies, such as prosthetic over-contouring, splinted restorations, and occlusal equilibration, are reviewed with attention …
