Qualitative Thematic Analysis Of Crisis Communications From The Digital Pulpits Of Megachurches During Covid-19, Ralph Dustin Henderson

Doctoral Dissertations and Projects

The purpose of this qualitative thematic analysis multi-case study was to explore how secular crisis communication theories were adopted and modified by theological themes in U.S. megachurches during the first six weeks of the COVID-19 pandemic related lockdowns. Image Repair Theory (IRT), Discourse Renewal Theory (DRT), and Rhetorical Arena Theory (RAT) were examined alongside Christian themes (Theodicy, Radical Love, Physical Care, and Nontraditional Stakeholder Scope). Thematic analysis of sermon transcripts from 18 megachurches showed that IRT modified: high-attribution tactics were minimal; denial (via IMRA theodicy) defended the Church Universal (CU); evasion justified Church Local (CL)actions; and offensiveness reduction (esp. Transcendence) …

Impacts Of Boundary Conditions And Parameter Heterogeneity On The Simulation And Prediction Of Water Inflow In Coal Mines, Ji Qiang, Wu Zhenjiang, Yao Yingying

Coal Geology & Exploration

Background Accurate prediction of water inflow in coal mines is essential for ensuring safe mining operations. Three-dimensional (3D) groundwater numerical models can be used to characterize hydrogeological conditions in mining areas and simulate the dynamic processes of water inflow, providing a theoretical basis for scientifically predicting mining-induced water inflow. However, there is a lack of a clear understanding of the impacts of the boundary conditions with surface water-groundwater interactions and the heterogeneity of aquifer permeability coefficients (K) on the simulation and prediction of water inflow during coal mining. Methods This study developed a 3D transient groundwater numerical model …

An Experimental Study On The Seepage Characteristics Of Sandstones With Different Numbers Of Fractures Before And After Grouting, Chen Juntao, Zhou Haoyu, Yu Junjian, Li Guo, Fan Mingjin, Li Lu, Wang Yunhao

Coal Geology & Exploration

Background Grouting in surrounding rocks serves as a conventional approach to controlling disasters in coal mine roadways. The developmental degree of fractures significantly influences the reinforcement and sealing effects of grouting. Methods To determine the changes in the impermeability of fractured surrounding rocks before and after grouting, this study investigated sandstones—the most common sedimentary rocks in coal mines. Using laboratory experiments and numerical simulations, this study explored the permeability variations of sandstone specimens with varying fracture numbers under different confining pressures and assessed the impact of grouting on their seepage performance. Through triaxial compression-seepage experiments using a Rock Top multi-field …

Impact Of Prostate Volume On Dose Fall-Off And Organ-At-Risk Exposure In Vmat For Prostate Cancer, Zhikang Jiang

Masters Projects

Prostate cancer remains one of the most prevalent malignancies among men, with radiotherapy, particularly VMAT—playing a central role in its management. VMAT allows for highly conformal dose delivery, but treatment planning must strike a careful balance between achieving steep dose gradients around the prostate and minimizing radiation exposure to nearby organs at risk (OARs), such as the bladder and rectum. This study aimed to evaluate how prostate volume influences dose fall-off characteristics and OAR dose exposure in VMAT treatment plans, providing insights into optimizing radiotherapy for patients with varying prostate sizes. A retrospective analysis was conducted on 50 prostate cancer …

The Effect Of Qber Estimation On The Efficiency And Security Of Quantum Key Distribution, Sufyan Al-Janabi

Baghdad Science Journal

Quantum Key Distribution (QKD) is a prominent solution to achieve proven secure data transmission between legitimate users despite any assumptions about the eavesdropper's computational power (given that the laws of quantum mechanics are correct). This remains true even under attacks by quantum computers. In recent years, there has been a great research interest in developing enhanced security constructions based on QKD. This is mainly driven by the envisioned threats of quantum computers to the traditional information security infrastructure based on public key cryptography. This research lies under the wide umbrella of the so-called post-quantum cryptography. However, for any QKD protocol, …

An Experimental Investigation Of Federal Messaging On Public Support For Enforcement- And Treatment-Based Approaches For Opioid Overdose Prevention In South Carolina, Lídia Gual-Gonzalez, Hunter M. Boehme, Peter Baker, Melissa Nolan Ph.D., Mph

Faculty Publications

Background

As the opioid overdose crisis continues to produce excessive morbidity and mortality in the United States, government agencies have applied various approaches to prevent overdoses, including law-enforcement efforts (e.g., arresting people who use drugs, interrupting drug traffickers, etc.) and treatment-based approaches (e.g., naloxone, medications for opioid use disorder, etc.). Public perception and support of these approaches are relevant for informing policy, allocating resources, and effectively implementing community interventions to prevent drug-related harms.

Methods

Using an embedded informational survey design, we experimentally assessed whether public support for strategies to prevent overdose in South Carolina is influenced by language from federal …

Unpacking Digital Transformation – Constructing A Framework Based On Industry Use Cases, Khawaja Asjad Saeed, Andrew William Green, Alison Brooke Hedrick

Faculty Articles

Based on industry use cases, we identify six distinct types of digital transformation (DT), each grounded in a specific concept or enabling technology. These DT types can be implemented individually or combined to drive transformation initiatives. While deploying a single DT type often focuses on improving operational efficiency or streamlining existing workflows, initiatives that combine multiple DT types tend to pursue more ambitious goals, such as the creation of new products, services, or business models. However, the complexity increases significantly with the integration of multiple DT types, as organizations must not only address behavioral changes but also overcome technical challenges …

Relationship Of A Business Simulation Course To Act Applied Math Outcomes, Brenda Lorraine Savage

Walden Dissertations and Doctoral Studies

Little evidence links the use of business simulations to advances in the higher order thinking skills that high school students need to prepare for careers in finance. The problem for this study was that students in three southern high schools had limited success on the ACT Applied Math Assessment, and there was a need to explore the relationship of a newly implemented stock market trading simulation course to student success on the assessment. Kolb’s experiential learning theory, which was aligned to the simulation activities, guided the study. The purpose of this quantitative predictive study was to determine whether participation in …

Attitudes Toward Seeking Mental Health Services Among Young African American Same-Sex-Oriented Men, Anthony Earl Fox

Walden Dissertations and Doctoral Studies

In 2018 suicide was the second leading cause of death for young people between the ages of 15 and 24 (CDC, 2018). Suicide and other factors like HIV, depression, and oppression may serve as barriers to seeking counseling among African American same-sex-oriented men ages 18-26. Due to a previous gap in the literature regarding barriers to seeking counseling, this study may support counselors in finding ways to address the disparity in counseling utilization among this population. Grounded in queer and social identity theories, the purpose of this quantitative study was to examine if adverse childhood experiences, current civic unrest, HIV, …

Seismic Anisotropy Of Sandstone Aquifers In Coal Seam Roofs, Yu Hang, Chen Tongjun

Coal Geology & Exploration

Objective The identification and assessment of sandstone aquifers in coal seam roofs play a vital role in the safe mining of mines. Investigating the rock physics and amplitude variation with incidence and azimuth (AVAz) responses of these sandstone aquifers is critical to the prevention and control of water hazards in mines. Methods By integrating rock physical models Voigt-Reuss-Hill (VRH), differential equivalent medium (DEM), Hudson, and Wood, as well as Gassmann’s anisotropic fluid substitution theory, this study proposed a rock physics modeling method for fractured sandstones of the horizontal transversely isotropic (HTI) media type (hereafter referred to as HTI sandstones).
