On Neumann Boundary Conditions For Nonlocal Models With Finite Horizon, Scott Alex Hootman-Ng

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Nonlocal models are have recently seen an explosive interest and development in the context of fracture mechanics, diffusion, image processing, population dynamics due to their ability to approximate differential-like operators with integral operators for inherently discontinuous solutions. Much of the work in the field focuses on how concepts from partial differential equations (PDEs) can be extended to the nonlocal domain. Boundary conditions for PDEs are crucial components for applications to physical problems, prescribing data on the domain boundary to capture the behavior of physical phenomena accurately with the underlying model. In this thesis we specifically examine a Neumann-type boundary condition …

Electronic Theses and Dissertations

Background. Shame and self-criticism are mechanisms shown to influence eating disorders (EDs). Self-compassion has been theorized to target shame and self-criticism and is a protective factor against EDs. One intervention shown to increase self-compassion and reduce shame and self-criticism is the Mindful Self-Compassion program (MSC). However, MSC has yet to be tested among individuals with an ED diagnosis. The current study investigated the feasibility, acceptability, and preliminary outcomes of MSC delivered in a live, online format among individuals with an ED. Methods. Sixty-one participants completed baseline questionnaires measuring ED symptoms, trait self-compassion, self-criticism, and shame. Participants also answered questionnaires at …

Analysis Of The Relationship Between Flow Patterns In The Post-Stenotic Region Of Model Arteries And Stenosis Severity., Michael Laroche

Electronic Theses and Dissertations

In this study, contour fields of mean age and turbulence kinetic energy (TKE) in the post-stenotic region of model arteries were analyzed to explore their correlation with FFR. While both high and low FFR cases exhibited similarities with an inner low-age region and an outer high-age region, low FFR cases displayed asymmetry in their low-age regions due to eccentric stenosis. Moreover, gradients of age across the artery diameter were more pronounced for low FFR cases. Additionally, low FFR cases demonstrated significantly higher TKE in the post-stenotic blood jet stream compared to high FFR cases that are reflected in low-age boundary …

Breaking The Silence: Exploring The Impact Of Supervisor Vulnerability On Menstrual Disclosures At Work, Marilla Hayman

Graduate Theses and Dissertations

Management research has traditionally overlooked the significance of the human body in the workplace. However, recent recognition of organizational body work has prompted the examination of biological processes such as pregnancy and breastfeeding. Menstruation, however, has received little attention, despite the challenges faced by menstruating employees. The invisibility and silence around menstruation at work hinders managers' understanding of employee needs and prevents employees from accessing needed accommodations. An important first step in remedying this problem is understanding the factors influencing employees to disclose their menstrual symptoms and seek support. Bringing together theories of organizational body work and concealable stigmas, this …

Model comparisons are performed in terms of likelihood measures and cross-validation. The Hurdle model for sesa and rutu and the Negative Binomial model for whim effectively captured spatial patterns, highlighting potential hotspots. Mean predictive count further emphasized …

Diversity Equity And Inclusion Education: An Evaluation Of The Safe Zone Allies Program, Shannon E. Hart

Graduate Theses and Dissertations

Diversity, Equity, and Inclusion gained unprecedented popularity from 2019 to 2022. The tide turned in 2023, and Anti-DEI legislation continues to gain momentum nationwide. This backlash may be warranted, as research demonstrates that DEI can backfire. DEI programs remain unregulated, understudied, and often paradoxically under-supported despite their potential to catalyze positive social change. Two studies were conducted to begin creating standardized, accessible, and evidence-based DEI best practices. Safe Zone Allies, a LGBTQIA+ specific DEI program was selected for program review because; (a) it was not developed hastily, (b) it was not siloed, and (c) the curriculum is evidence-based.

What Is A Person? How Does One Become A Morally Good Person? The Intuitive View!, Tancredo Tivane

Graduate Theses and Dissertations

This thesis centers around two philosophical problems: the concept of a person and the process by which one becomes a morally good person. Drawing on the works of philosophers such as Harry Frankfurt, Strawson, and A.J. Ayer, it begins with an inquiry into what it means to be a person. It argues that while humanhood, with its rational capacities, is a contingent rather than a necessary condition, it can serve as an accurate predictor of personhood. The thesis posits that personhood is an achievement rather than an inherent state, facilitated by interactions within a social framework that refine these rational …

The objective of this study was to evaluate the effects of CC (i.e., with and without CC) across various physical, hydraulic, biological, and chemical soil indicators in the Lower Mississippi River …

Real-Time Delphi Study: Perspectives Of An Autistic Panel On Independent Living, Celeste Michaud

Graduate Theses and Dissertations

The shift from institutional living to community integration for people with disabilities, including autistic people, has been significantly influenced by legislative measures and advocacy. Despite these efforts, autistic youth and adults still experience a unique transition to independent living compared to their peers with other disabilities. Studies have reported that autistic adults are more likely to remain in the family home and less likely to live independently post-high school (Anderson et al., 2014). Existing literature and legislation illustrate a fragmented approach to defining and measuring independent living for autistic adults, often driven by non-autistic perspectives (Cribb et al., 2019). This …
