Evaluating A Dual-Beacon Hartmann Turbulence Profiling Technique Using Wave Optics Simulations, Benjamin C. Wilson, Matthew Kalensky, Santasri Bose-Pillai, Jack E. Mccrae

Faculty Publications

Resolving how optical turbulence varies along a propagation path remains a key challenge for designers of free-space optical propagation systems. Instruments such as scintillometers and differential image motion monitors are commonly used, but only provide path-integrated turbulence estimates. Point sensors provide localized estimates of turbulence strength and can be used to generate path-resolved profiles when an array of point sensors are distributed along the optical path. However, this approach can be costly and complex to deploy in certain environments. Alternatively, a single point sensor can be mounted on a mobile platform that collects data while traversing the optical path, although …

An organizational change process guided …

Exploring The Occupational Risks Among Human Service Professionals: A Trauma-Informed Approach To Caring For Others And Ourselves, Shaian Kong

Master of Arts in Human Services

It is known that human service practitioners are often expected to maintain empathy, compassion, emotional regulation, and professionalism during high-stress or uncertain situations. These experiences expose practitioners to a unique intersection of trauma. While helping others through their own trauma, practitioners may also experience symptoms such as intrusive thoughts, emotional exhaustion, sleep disturbances, hypervigilance, and avoidance despite not directly experiencing the traumatic events themselves. Current literature highlights these existing occupational risks that may hinder sustained career development, increased compassion fatigue, and affect workplace standards and support. With things like frequent increase in workloads, workforce shortages, and insufficient professional support, practitioners …
