Impact Of Sensory Organization Tasks On Prefrontal Cortex Activity In Older Women: A Comparative Fnirs Study Of Osteoarthritis And Healthy Aging, Alka Bishnoi, Yang Hu, Manuel E. Hernandez

Faculty Research, Scholarly, and Creative Activity

Introduction: Osteoarthritis (OA), a prevalent musculoskeletal condition, is associated with an increased risk of falls. Maintaining posture relies on visual, vestibular, and proprioceptive inputs, but these systems can be compromised due to aging or disease, heightening fall risk. Such impairments may result from neuromuscular decline and reduced cognitive or visuospatial processing abilities. This study aimed to investigate prefrontal cortical (PFC) activation patterns during clinical sensory organization tasks (SOT) using functional near-infrared spectroscopy (fNIRS) in older women with OA and healthy controls (HOA). We hypothesized that PFC activation would increase as SOT conditions became more challenging, but that increases would be …

Learning About The Transit Passenger Experience From Microblogging Posts, Egbe Etu Etu, Asha Weinstein Agrawal, Jordan Larot, Chaitanya Tatipigari, Imokhai Theophilus Tenebe

Faculty Research, Scholarly, and Creative Activity

Transit agencies often track delays and malfunctions but may overlook riders’ real-time social experiences. To fill this gap, we analyzed 559 tweets from 2020 to 2023 that captured personal accounts of public transport use. Using thematic analysis, we found that 74% of posts criticized other passengers’ behavior, far outweighing comments on transit ride quality, such as complaints about delays (25%). Notably, 86% of tweets expressed negative sentiment, though some highlighted exceptional service. These findings demonstrate that interpersonal dynamics are a key contributor to riders’ experiences and illustrate the nature of the interactions that riders like and dislike.

The Ethics Of Military Influence On Politics, Brenner M. Fissell

Faculty Publications

Military rule is common across the world, but this form of government is incompatible with the rule of law for various reasons. To prevent this, Western democracies such as the United States impose a strong norm of civilian supremacy over military officials. The most important role of this norm of “civilian control” in America today is to police the interventions of senior military officers’ influence in politics. While the standard position is that the military should be “apolitical,” this limitation does little work in helping senior officers understand permissible conduct, as nearly every issue confronting them will implicate matters of …
