Variable-Order Fractional Partial Differential Equations: Analysis, Approximation And Inverse Problem, Xiangcheng Zheng

Theses and Dissertations

Variable-order fractional partial differential equations provide a competitive means in modeling challenging phenomena such as the anomalous diffusion and the memory effects and thus attract widely attentions. However, variable-order fractional models exhibit salient features compared with their constant-order counterparts and introduce mathematical and numerical difficulties that are not common in the context of integer-order and constant-order fractional partial differential equations.

This dissertation intends to carry out a comprehensive investigation on the mathematical analysis and numerical approximations to variable-order fractional derivative problems, including variable-order time-fractional, space-fractional, and space-time fractional partial differential equations, as well as the corresponding inverse problems.

Composition Of Musical And Visual Devices To Create Moments Of Resolution In Marching Arts Production Design, Ryan John Williams

Theses and Dissertations

This research study identifies techniques of creating and releasing musical tension in audio-visual performance media, specifically within the marching arts. A successful composition in this medium is defined, in part, by the coordination of effects between pitched musical elements, non-pitched (percussive) musical elements, and movement (choreographed) elements. Such compositions create a concert performance situation in which there is aesthetic gratification and a sense of sophistication in which aural stimuli interact in congruence and in conjunction with visual stimuli. By identifying the creative practice through conversation with practitioners, designers, choreographers, and composers, the common practices of the genre can be identified …

The Health Care Commons: A Philosophical Approach, Roel Feys

Theses and Dissertations

This project is the first large-scale and systematic effort to bridge the fields of commons research and biomedical ethics, with the aim of furthering key debates in both areas of inquiry. The aims and contributions of the project are twofold.

First, I argue that commons research is valuable to bioethics, because it provides a language to talk about health care institutions. I critically discuss commons research’s main conceptual tools in the context of health care: the Institutional Analysis and Development (IAD) framework, the design principles of successful commons, parallel experimentation, and polycentric governance regimes. This conceptual apparatus can help to …

Fostering Resilience In Correctional Officers, Jon Thomas Arthur Gist

Theses and Dissertations

A significant portion of the literature regarding corrections emphasizes the negative factors and outcomes related to the job. The career of a correctional officer includes a stressful, demanding, and unpredictable work environment. Correctional institutions are struggling to keep a correctional staff that can adapt to internal and external forces. Several studies have shown that correctional officers frequently encounter severe inmate misconduct, resulting in high levels of stress, low job satisfaction, and intentions of leaving the job. However, research begs the question of what makes a correctional officer resilient and functional at work?

No prior study has applied a mixed-methods study …

Addressing Unconscious Bias, Power, And Privilege To Increase Cultural Competence Skills In Healthcare Faculty: Intersecting Critical Race Theory And The Pyramid Model For Intercultural Competence, Christina B. Gunther

Theses and Dissertations

Inequity in healthcare has long been understood to be caused by individual and structural racism in the health system. Little progress has been made in diminishing the disparities that exist between Black and African American minoritized populations and the White majority. Cultural competence training in healthcare has focused on surface level differences in ethnicities, including language and religious practices, while ignoring difficult to address topics such as race and racism. This action research study, using a convergent mixed-methods design, attempted to address the gap in knowledge of race and racial structures in healthcare for the faculty in the college of …

Theses and Dissertations

Introduction

2009 H1N1 Pandemic: The historical 2009 H1N1 Influenza pandemic, which had a CDC estimated accrued disease burden of 100.5 million illnesses, 936,000 hospitalizations, and 75,000 deaths from 2009 to 2018, resulted in a declared state of emergency nationally, with ensuing diminished vaccine confidence and amplified fears of infection, prompting some to pursue flu vaccination, and others to forego. Although the Centers for Disease Control and Prevention (CDC), and its Advisory Committee on Immunization Practices (ACIP) recommend an annual flu vaccine for individuals 6 months of age and older as the “first and best” defense against influenza, a low percentage …

Finding Their Strengths, Dreams And Struggles: A Narrative Inquiry Of High School Students Independent Reading Habits, Tori T. Simmons

Theses and Dissertations

The ability to read and understand texts are important to student’s success in school and life. However, many secondary students enter without the skills needed to handle the rigor and amount of reading they will meet as they matriculate high school. Yet, this is not the case for those who struggle to read most. Allington (2013) found that students who struggle the most to read are also those who given the least amount of time to reading and the most to worksheets (p. 526). Therefore, this study hopes to better understand the reading histories of three high school students and …

Distinguishing Neuro-Markers Of Math Learning Disability Using Eeg Coherence, Jessica C. Luedke

Theses and Dissertations

Math learning disability (MLD) is a neurodevelopmental disorder that results from specific cognitive deficits involved with numeric computation and arithmetic that cannot be attributed to low general ability. Although MLD has a significant impact on life outcomes, only a few studies have evaluated unique neurological profile differences between those with and without specific math deficits. EEG coherence has been useful for evaluating neural disconnections in children with neurodevelopmental disorders but has never been used to explain cognitive deficits found in children with MLD. The current study contributed to the literature by evaluating at-rest electrocortical signatures in those with MLD (n …

The Effects Of Super-Resolution Microscopy On Colocalization Conclusions Previously Made With Diffraction-Limited Systems In The Biomedical Sciences, Madison Emily Yemc

Theses and Dissertations

Super-resolution microscopy, also known as nanoscopy, is now established in the field of microscopy. The evolution of super-resolution microscopy techniques has allowed many scientists to peer past the most significant limitation in conventional fluorescence microscopy – the diffraction limit. Super-resolution microscopy systems are able to resolve two points that are less than 250 nm apart, which supersedes the resolution of diffraction limited systems. Colocalization studies are frequently used in the biomedical sciences to measure the close physical association and functional interaction of two biological structures. Previous colocalization conclusions made with conventional fluorescence microscopy are largely based on how the colors …

Steady-State And Transient Study Of Flow Boiling In Microchannels With Microgrooves/Micronozzles, Congcong Ren

Theses and Dissertations

Microchannel flow boiling is one of the most desired cooling solutions for high power electronics. Owing to the high latent heat of vaporization, high heat fluxes can be achieved through phase-change heat transfer. However, the enhancements of (critical heat flux) CHF and heat transfer coefficient (HTC) are usually inhibited by the transitional flow patterns, which highly influence the liquid rewetting. In the past two decades, many techniques have been explored to enhance the liquid rewetting in microscale.

In this dissertation, four parallel micro-grooves fabricated on the bottom of five microchannels (W=200 μm, H=250 μm, L=10 mm) were designed to promote …

The Literacies Of Adolescents With International Experiences, Caitlin Hanzlick Rasmussen

Theses and Dissertations

This dissertation reports the findings of a study on how international experiences impact adolescents. Data were gathered from interviews with and writing samples from seven participants with varying international experiences. A critical perspective and existing research in New Literacy Studies (NLS), on study abroad programs, and on transnationalism framed the study and predicted much of what was found about the literacies of adolescents with international experiences. However, five new findings emerged as significant about adolescents’ utilitarian, oral, geolingual, critical, and cosmopolitan literacies uniquely impacted by travel. From these findings, new insights emerged about the importance of embracing multiple forms of …

Effects Of A Physical Activity Intervention On The Stress Reduction Of Underserved Adolescent Youth, Gwenyth C. Asbury

Senior Theses

Stress levels of American teenagers are rising. Studies show that teens are reporting higher stress levels than what they perceive to be healthy and that these levels are higher than the levels of perceived stress reported by adults (APA, 2013). In addition to reporting unhealthy levels of stress, adolescents are reporting feeling overwhelmed and depressed due to their stress (APA, 2013). These findings are especially true for underserved adolescents who are more likely to have exposure to violence, discrimination, racism and conditions of poverty in addition to experiencing the typical stressors associated with adolescence (American Academy of Child and Adolescent …

Characterizing Patterns Of Adherence To Physical Activity Goals In Behavioral Weight Control, Melissa Lee Stansbury

Theses and Dissertations

Introduction: Many individuals fall short of the physical activity (PA) goals provided during lifestyle programs, and there is considerable variability in weight loss response and adherence to recommendations for behavior change. Weight loss response within the early weeks of program initiation predicts future weight loss success; however, little is known about what distinguishes those who respond well to treatment from those who fail to respond. Exposing the behavioral patterns which underlie weight loss response may point towards targets for treatment optimization. The purpose of this study was to (1) characterize individuals with distinct patterns of adherence to PA goals during …

Early Breastfeeding Practices Contribute To Exclusive Breastfeeding In Bangladesh, Vietnam And Ethiopia, Phuong Hong Nguyen, Sunny S. Kim, Lan Mai Tran, Purnima Menon, Edward A. Frongillo Jr.

Faculty Publications

Limited evidence exists on the complex relationship among interventions, early initiation of breastfeeding (EIBF), prelacteal feeding and exclusive breastfeeding (EBF). We examined whether early breastfeeding practices are associated with EBF and how much improving EIBF and non-prelacteal feeding contributes to increased prevalence of EBF. Survey data were collected in 2010 and 2014 as part of impact evaluations of Alive & Thrive (A&T) interventions to improve infant and young child feeding (IYCF) practices in Bangladesh, Vietnam and Ethiopia. Multivariable logistic regression analyses were used to examine effects of interventions and early breastfeeding practices on EBF. Structural equation modelling quantified the direct …
