Bayesian, Frequentist, And Information Geometry Approaches To Parametric Uncertainty Quantification Of Classical Empirical Interatomic Potentials, Yonatan Kurniawan

Theses and Dissertations

Uncertainty quantification (UQ) is an increasingly important part of materials modeling. In this paper, we consider the problem of quantifying parametric uncertainty in classical empirical interatomic potentials (IPs). Previous work based on local sensitivity analysis using the Fisher Information has shown that IPs are sloppy, i.e., are insensitive to coordinated changes of many parameter combinations. We confirm these results and further explore the non-local statistics in the context of sloppy model analysis using both Bayesian (MCMC) and Frequentist (profile likelihood) methods. We interface these tools with the Knowledgebase of Interatomic Models (OpenKIM) and study three models based on the Lennard-Jones, …

Pilot Testing Okay With Asthma™: A Digital Story For Psychosocial Asthma Management, Tami Hodges Wyatt

Dissertations

Asthma, an obstructive airway disease characterized by recurrent episodes of breathlessness and wheezing, is the most prevalent chronic illness among children in the United States. An estimated 7.7 million American children have asthma. Health experts suggest that cognitive, emotional, and behavioral variables contribute to its severity. To date, asthma education programs have focused on asthma triggers, behaviors to manage asthma, and asthma medications; however, they have not addressed the emotional component of children's experience with asthma. This is important because the way children feel about their asthma, or their attitude, affects what they learn and how they apply it. The …

To Lift Or Not To Lift: An Institutional Ethnography Of Patient Handling Practices, Hans-Peter De Ruiter

Dissertations

The handling (lifting, mobilizing, moving etc) of patients is an integral part of the carework in health-care institutions. For obvious reasons, this puts healthcare providers at risk for musculoskeletal injuries (MSIs); furthermore the risk of such injuries has been considered an inherent risk of care work. In the last decade a concerted effort has been made to decrease (with the goal of eliminating) caregiver injuries by implementing safe patient handling programs (SPHP). These programs are presented as evidence-based algorithms that require the use of mechanical lifting devices. Institutions implement SPHPs as policies and procedural guidelines to which caregivers must conform. …
