Faculty Perceptions Of Readiness And Confidence For Teaching Online: An Evaluation Of Online Professional Development, Kevin Brent Forman

Theses and Dissertations

Regardless of how prepared faculty were to teach online classes, the COVID-19 pandemic forced leaders of universities and colleges and faculty nationwide to pivot to emergency remote teaching and forced students to take online classes. To prepare faculty for the shift to online instruction, administrators in colleges and universities provided resources, such as online trainings, to orient less experienced instructors to principles of online education. The Online Pedagogy Program (OPP) at Midwest Community College was developed quickly in response to the need for urgent training in effective online instruction. After 300 faculty completed the training, an evaluation of the Online …

Students who routinely receive ODRs run the danger of failing their classes and are more likely to have been …

Implementation Of A 3d Laser Profiler System Into A Non-Contacting Method For Rnt & Stress Measurements, Caio Neto Penna

Theses and Dissertations

Continuous welded rail (CWR) is susceptible to the development of internal forces in the rail due to thermal effects that can lead to track buckling. Railroads typically deal with the internal stresses in the rail through the inspection of the rail neutral temperature (RNT) which is the temperature at which the internal force is zero. The existing methods in the industry to measure RNT are contacting, destructive, disruptive to railroad operations, and ineffective. The proposed concept is a promising non-contacting, non-disruptive and reference-free technique to measure RNT and the stress state in the rail. The method is based on the …

Insurance Status And Cancer Staging, Time To Treatment, And Mortality: Examining Cancers Of The Breast, Colon, And Lung, Gabriel A. Benavidez

Theses and Dissertations

Introduction: When examining cancer outcomes, timely detection and treatment are critical factors for favorable prognoses. Previous studies have shown that individuals with public health insurance, specifically Medicaid, have worse cancer outcomes than those with private insurance. While differences in socioeconomic status may account for this disparity, one potential area for further investigation is the effect of Medicaid enrollment timing on cancer outcomes. In some states, individuals may not be eligible for Medicaid until after their cancer diagnosis, potentially nullifying health insurance benefits. This analysis examines the impact of Medicaid enrollment timing on cancer outcomes by comparing patients not enrolled in …

Phoneme Stability In Speech Production Of Cognate And Non-Cognate Nouns In A Bilingual With Aphasia, Katherine Vlach

Theses and Dissertations

With the growing bilingual population in the world comes a greater incidence of bilingual aphasia, a communication disorder characterized by expressive or receptive language impairment in one or both of a bilingual speaker’s languages. The cognate facilitation effect, which has greatly been explored in healthy bilingual studies, has shown that cognates are named faster and more accurately than non-cognates; as the cognate facilitation effect is also retained in bilingual speakers with aphasia, it is thought that cognates could potentially be used as a treatment tool to facilitate lexical access, particularly when a bilingual speaker with aphasia presents with one of …

Bayesian Spatial And Spatio-Temporal Models For Complex Data Sets, Rongjie Huang

Theses and Dissertations

The cost of testing for infectious diseases can be high, and analyzing large amounts of historical data to forecast disease prevalence can be a time-consuming process. Group testing techniques offer a way to decrease the expenses associated with testing, but this comes at the cost of increased complexity of the data structure due to grouping and imperfect testing when compared to individual-level testing. In this dissertation research, we propose two Bayesian mixed effects spatial group testing regression models: one for areal data and the other for point process data. The former model utilizes a conditional autoregressive (CAR) prior for areal …

Additionally, this research seeks to examine psychophysiological responses from these interreacting frameworks using webcam eye-tracking technology, which was developed recently and has not been previously used …

Framing Police Brutality: An Analysis Of Newspaper Coverage Of Walter Scott’S Murder, Shamira S. Mccray

Theses and Dissertations

This research analyzes news articles about the killing of Walter Scott in 2015 to determine how frames changed over time and across platforms. Previous studies have found that news coverage of police violence against Black men has not always been fair. Instead, the narrative of official sources, like law enforcement, prove dominant. These same research articles typically focus on the way national news outlets frame incidents like Scott’s.

But this thesis takes a deeper look at how state newspapers framed Scott’s murder. I analyzed the frames and sources found in nearly 200 articles published by The Post and Courier and …

Words Evaporate, The Images Remain: Testing Visual Warnings In The Context Of Intentions To Vape Among U.S. Adults As An Expansion Of The Theory Of Planned Behavior (Tpb), Carl Arland Ciccarelli

Theses and Dissertations

This dissertation applied the Theory of Planned Behavior (TPB) model variables of attitudes, subjective norms, and perceived behavioral control, along with the variable of fear to explain individuals’ behavioral intentions to vape. Previous studies have explored the social appeal, intrigue, and potential consequences of vaping among adolescent and college student populations. However, these past studies have largely relied upon focus groups and self-reported data conducted among samples of teen, adolescent, and college student populations. Thus, the aims and designs of these previous vaping studies may have been lacking in construct validity and a theoretical approach from which to explain behavioral …

Leveraging Programmable Switches To Enhance The Performance Of Networks: Active And Passive Deployments, Elie Kfoury

Theses and Dissertations

The performance of networks today is drastically affected by: 1) switches equipped with large buffers, referred to as “bloated buffers”: due to the lack of programmability and traffic visibility in legacy switches, operators nowadays configure large buffers statically without considering the characteristics or dynamics of flows. Such buffers increase the delays on packets, causing the Quality of Service (QoS) of networked applications (e.g., voice over IP, web browsing) to degrade; 2) switches forwarding packets on a best-effort basis: traffic crossing a switch is heterogeneous in many ways. Mixing such traffic in a single queue without any QoS measures can drastically …

Leveraging Church Environments To Promote Rural Physical Activity And Healthy Eating, Kelsey Rothera Day

Theses and Dissertations

Rural residents experience a greater burden of chronic disease related to physical inactivity and poor diet than their urban counterparts. A promising strategy to improve these health behaviors in rural areas is to leverage existing structures that may support physical activity and healthy eating, such as churches, in public health interventions. Three studies were conducted as part of this dissertation. They were designed to: 1) examine whether the walkability and healthy food density of neighborhoods surrounding rural and urban churches are associated with race, socioeconomic status, and rural/urban status; 2) examine rural church leaders’ views on the role of faith-based …

Breaking Down The Human: Disintegration In Nineteenth-Century Fiction, Benjamin Mark Driscol

Theses and Dissertations

This dissertation brings together nineteenth-century texts written by Mary Shelley, Edgar Allan Poe, Gustave Flaubert, Benito Pérez Galdós, Rachilde, and Oscar Wilde in order to trace a common thread weaving in and out of literature produced during this period: the theme of corporeal disintegration and its psychic and social ramifications. Each of the analyzed works considers the human condition from diverse perspectives and portrays the breakdown in interpersonal relationships as characters become estranged from society and each other. Of course, the examples considered here are canonical ones widely discussed in criticism—some of them as forebears of literary Modernism, for which …

Marine Anoxia Initiates Giant Sulfur-Bacteria Mat Proliferation And Associated Changes In Benthic Nitrogen, Sulfur, And Iron Cycling In The Santa Barbara Basin, California Borderland, David J. Yousavich, De'marcus Robinson, Xuefeng Peng, Sebastian J.E. Krause, Frank Wenzhoefer, Felix Janßen, Na Liu, Jonathan Tarn, Frank Kinnaman, David L. Valentine, Tina Treude

Faculty Publications

The Santa Barbara Basin naturally experiences transient deoxygenation due to its unique geological setting in the southern California Borderland and seasonal changes in ocean currents. Long-term measurements of the basin showed that anoxic events and subsequent nitrate exhaustion in the bottom waters have been occurring more frequently and lasting longer over the past decade. One characteristic of the Santa Barbara Basin is the seasonal development of extensive mats of benthic nitrate-reducing sulfur-oxidizing bacteria, which are found at the sediment–water interface when the basin's bottom waters reach anoxia but still provide some nitrate. To assess the mat's impact on the benthic …

Effects Of Fucoidan Supplementation On Inflammatory And Immune Response After High-Intensity Exercise, Bridget A. Mcfadden, Caroline S. Vincenty, Akexa J. Chandler, Harry P. Cintineo, Blaine S. Lints, Gianna F. Mastrofini, Shawn M. Arent Ph.D., Cscs*D, Fissn, Facsm, Fnak

Faculty Publications

Introduction: High-intensity exercise (HIE) can damage the musculotendon complex and impact the immune response, resulting in post-exercise inflammation. Sufficient rest and recovery will improve muscular resilience against future damaging bouts; however, HIE with minimal durations of rest is common in athletic competitions that facilitate persistent inflammation and immune dysregulation. Fucoidans are fucose-rich sulfated polysaccharides with demonstrated anti-inflammatory and pro-immune responses. Fucoidans may improve inflammation and immune responses, which may prove beneficial for individuals who regularly engage in repeated HIE. The research purpose was to investigate the safety and efficacy of fucoidans on inflammatory and immune markers following HIE. Methods: Eight …

In The Ceo We Trust: Negative Effects Of Trust Between The Board And The Ceo, Kee-Hong Bae, Sadok El Ghoul, Zhaoran (Jason) Gong, Omrane Guedhami

Faculty Publications

In this study, we investigate whether and how trust between board members and the CEO (board–CEO trust) affects the performance of mergers and acquisitions. Contrary to conventional wisdom, we find that firms with higher levels of board–CEO trust exhibit poor M&A performance. High trust is associated with low acquisition announcement returns, long-term stock return performance, and post-deal operating performance. This negative effect of board–CEO trust is more pronounced among acquiring companies prone to agency problems. Our results suggest that, in the institutional setting of corporate boards, high trust can be too much of a good thing.

Issue Of Data Imbalance On Low Birthweight Baby Outcomes Prediction And Associated Risk Factors Identification: Establishment Of Benchmarking Key Machine Learning Models With Data Rebalancing Strategies, Yang Ren, Dezhi Wu, Yan Tong, Ana Lopéz-De Fede, Sarah Gareau

Publications

Background: Low birthweight (LBW) is a leading cause of neonatal mortality in the United States and a major causative factor of adverse health effects in newborns. Identifying high-risk patients early in prenatal care is crucial to preventing adverse outcomes. Previous studies have proposed various machine learning (ML) models for LBW prediction task, but they were limited by small and imbalanced data sets. Some authors attempted to address this through different data rebalancing methods. However, most of their reported performances did not reflect the models’ actual performance in real-life scenarios. To date, few studies have successfully benchmarked the performance of ML …
