Journal of Aviation/Aerospace Education & Research

This study evaluated the effectiveness of tactile cueing integrated into a pilot’s headset on pilot altitude control during simulated instrument conditions. Pilots typically rely on visual and auditory inputs to maintain situational awareness, but in high-workload or instrument meteorological conditions (IMC), these channels can become overloaded. One underutilized alternative for alerting is a tactile cueing apparatus. Using an X-Plane simulation of a Piper Archer equipped with a G-1000 avionics suite, 39 FAA-certified pilots flew two precision approaches. The experimental group (n = 20) received haptic cues via ear seal-embedded tactors when deviating from assigned altitude or glideslope. The control group …

Clinical Practice Guideline For Sepsis In Skilled Nursing Facility, Chinyere Okoroh

Walden Dissertations and Doctoral Studies

Sepsis is a life-threatening condition that can rapidly lead to organ dysfunction, septic shock, and death if not recognized and treated early. Older adults in skilled nursing facilities (SNFs) are especially vulnerable because of age-related physiological changes, chronic conditions, weakened immunity, and increased exposure to infections. Consequently, sepsis remains a major cause of hospital readmissions, mortality, and healthcare utilization among SNF residents. The SNF serving as the site for this Doctor of Nursing Practice (DNP) project experienced increased hospital readmissions associated with recurrent sepsis, highlighting the need for a standardized, evidence-based approach to sepsis recognition and management. The practice-focused question …

Linking Emotion Dysregulation To Autistic Traits Across Neurodiverse Samples, Rachel G. Mcdonald, Mary Isaac Cargill, Emily Lynch, Sadaf Khawar, Caroline Freden, Erin Kang

Department of Psychology Faculty Scholarship and Creative Works

Emotion dysregulation (ED) is defined as difficulty regulating emotions in response to activating situations, and subsequent difficulty choosing an environmentally appropriate strategy to modulate one’s emotions. Despite ED being identified as a transdiagnostic construct, little research has examined the links to constructs like social communication and interaction (SCI) and restricted and repetitive behaviors (RRBs). SCIs and RRBs are core components of neurodevelopmental conditions like autism, as well as other mental health conditions more broadly. This article sought to examine the effects of emotional dysphoria and emotional reactivity on SCI and RRBs. Caregivers of 99 youth (64 autistic) ages 6 to …

Toward Design-To-Fabrication Continuum For Open-Source Computational Robotic Ecologies In The Post-Anthropogenic Era, Celso Urroz

Electronic Theses and Dissertations 2020 - Present

Computational design and robotic fabrication have expanded architecture’s capacity to coordinate geometry, material behavior, machine operation, and environmental performance. Yet many design-to-fabrication workflows remain structured by industrial logics of separation, standardization, and control. Design is often abstracted from material execution, fabrication is treated as a downstream phase, and robotic systems remain concentrated within specialized or proprietary infrastructures. This dissertation addresses this problem by proposing the design-to-fabrication continuum as an open, transferable, and ecologically situated framework in which computation mediates among design intent, matter, machine, environment, and shared technical knowledge.

The research uses a practice-based methodology combining computational workflow development, material …

Price Tags Of Goodwill: The Examination Of General Strain Theory And Official Behavior, Kathryn A. Loving

Doctoral Dissertations and Projects

Applying the theoretical framework of Agnew’s (1992) General Strain Theory, this project aimed to understand the connection between strain-induced responses and improper official behavior, considering an individual’s intersectionality (sexuality). Despite extant empirical data recognizing that justice officials' duties expose them to a barrage of human misery, vicarious trauma, and intense circumstances that negatively impact their psyche, little research exists about how compassion fatigue relates to improper official conduct. When culturally induced expectations become divorced from an official despite a coordinated institutional emphasis, negative police responses can jeopardize public service. Because criminal justice officials are the backbone of public safety, it …
