Bridging The Divide: Exploring Stigma And Enhancing Belonging For Online Faculty In Higher Education, Stephanie L. Wanamaker

Electronic Theses and Dissertations

Online faculty in higher education experience stigma and negative perceptions regarding online education in academia.

Addressing The Problems Of Data Variations, Quality, And Scarcity In Training Deep Neural Networks, Jian Sun

Electronic Theses and Dissertations

The performance of deep neural networks (DNNs) is strongly influenced by the characteristics and quality of the underlying datasets. This Ph.D. dissertation addresses three pervasive data challenges-imbalance, quality degradation, and scarcity-that commonly hinder the effectiveness of DNNs in computer vision (CV) and natural language processing (NLP) applications.

Class imbalance remains one of the most frequent causes of degraded model generalization. While Focal Loss effectively mitigates inter-class imbalance by assigning higher weights to minority classes, it struggles with intra-class imbalance, particularly in video datasets where longer clips dominate feature representation. To address this, I implement and utilize …

Longevity, Resilience, And Thriving Of Women In Ministry: A Case Study Of Women In Ministry From A United Pentecostal Holiness Church, Eunice Cheryl Feltus Little

Electronic Theses and Dissertations

Abstract

The problem of ministry attrition caused by burnout is well documented.

High attrition rates throughout religious organizations and a lag in longevity and resilience contribute to a shortage of ministry workers. Some ministry workers leave the vocation because of stress and burnout, yet others persevere. Despite the possible adverse effects, many men and women find a sense of well-being and joy in ministry work. This qualitative distributive case study focused on those who stayed in ministry and the strategies …

Impact Of The Lace Index Scoring Tool On Sepsis Readmissions, Tabitha M. Keaty Sheppard

Managing The Mood: How Managerial Communication Shapes The Experience Of Emotional Labor Among Restaurant Employees, Brynn Olverson

Electronic Theses and Dissertations

Restaurant work is emotionally demanding work for servers and bartenders. Organizational Support Theory (Eisenberger et al., 1986) suggests that employees’ perceptions of their organizations’ support can bolster the negative side effects of such work. However, past instruments used to measure these perceptions do not distinguish between types of emotional experience, nor separate perceptions of emotional support from other forms of support. Likewise, OST notes that supervisors play a key role in influencing perceptions of organizational support, but more work is needed to determine specific communicative behaviors that can increase perceptions of organizational support. The study at hand proposes that managers' …

Data-Driven Optimization Of Memory Effects And Critical Components In Cascading Failure Interaction Networks, Md Farhan Tanvir

Electronic Theses and Dissertations

Cascading failures are a major concern for modern power systems‚ where a small failure can cascade through the network to create a large blackout. Because such an event could have catastrophic economic and social costs it is important to understand cascading failures‚ how to model them‚ and the possibility of reducing them. In this thesis‚ we develop a data-driven framework based on actual utility outage data to model and reduce cascading failures. The proposed methodology is based on generation-dependent interaction models and in this study interaction matrices obtained from historical outage events are used to describe the interaction between generations. …

The Fertilization President: A Rhetorical Analysis Of The United States’ Rebirth Of Pronatalism, Kara Vetch

Electronic Theses and Dissertations

The United States experienced one of the lowest birth rates in decades in 2024 and has been blamed by policymakers for poor economic and societal outcomes. To combat this, President Donald Trump signed an executive order to encourage healthcare insurances to lower the cost of fertility treatments. Policies encouraging more births align with pronatalist ideologies, the belief that higher national birth rates are better for society. Furthermore, Vice President JD Vance and social media influencers, Malcolm and Simone Collins, have built a strong resurgence of pronatalist ideologies through public addresses and interviews long before Trump’s executive order. For an in-depth …

Computational Modeling Of Biophysical Transport: Respiratory Drug Delivery And Tissue-Level Physics, Md Tariqul Hossain

Electronic Theses and Dissertations

The nasopharynx, the upper part of the pharynx located at the back of the nose serves as a critical hotspot for initial respiratory infections via inhaled transmission, largely due to the presence of specific surface receptors that pathogens can exploit for cell invasion, combined with a relatively sparse local mucociliary substrate. To enhance the therapeutic efficacy against certain pathogens, such as the SARS and Influenza viruses, it is therefore essential to improve the targeted delivery of drugs to the nasopharynx. This study explores the use of intranasal sprays as a method for drug administration and models the transport of sprayed …

Cyber Security Related To Agricultural Data Encryption Using Edge Computing Devices, Mohammad Ashik Alahe

Electronic Theses and Dissertations

Smart Agriculture increasingly relies on image-based sensing, edge computing, and artificial intelligence to support data-driven decision-making in modern farming systems. While these technologies improve productivity and resource efficiency, they also introduce significant cybersecurity risks, particularly agricultural images transmitted and processed in real-time on resource-constrained edge devices. Unauthorized access, data manipulation, and interception of image data can lead to incorrect agronomic decisions and severe economic consequences. Despite this risk, efficient and practical cybersecurity solutions for real-time agricultural imaging remain limited. This study addresses these challenges by developing and evaluating encryption-based cybersecurity frameworks tailored for real-time agricultural image protection on edge computing …

Defending Darnassus: Self-Disclosure Between Characters In World Of Warcraft, Molly Peterson
