Role Of Cellular Stress Responses In Innate Immune Defense Against Acute Respiratory Infections, Amit Sharma Dec 2025

Role Of Cellular Stress Responses In Innate Immune Defense Against Acute Respiratory Infections, Amit Sharma

LSU Doctoral Dissertations

The endoplasmic reticulum (ER) stress sensor inositol-requiring enzyme 1α (IRE1α) is an important regulator of innate immune cells. However, its role in pulmonary innate host defenses remains poorly understood. This dissertation elucidates the dual, context-dependent role of IRE1α in host defense against methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. We demonstrate IRE1α’s function as both a detrimental mediator of acute pathology and an essential facilitator of innate immune memory. Our work revealed that acute IRE1α activation during primary MRSA infection is detrimental. In lungs and alveolar macrophages (AMs), IRE1α is activated in response to MRSA infection. Consequently, IRE1α activation triggers a hyperinflammatory …

Educational Leadership's Role In Understanding Nil Policy Perceptions Among College Football Players, Carlton Rice Dec 2025

Educational Leadership's Role In Understanding Nil Policy Perceptions Among College Football Players, Carlton Rice

Tennessee State University Alumni Theses and Dissertations

This study examined educational leadership's role in understanding Name, Image, and Likeness (NIL) policy perceptions among college football players at an American Athletic Conference institution. Using Expectancy-Value Theory as the theoretical framework, the research explored how educational leaders interpret and communicate NIL policies to student-athletes, assessed student-athlete perceptions of leadership effectiveness, and investigated how leadership experiences influence attitudes toward NIL policies. The mixed-methods study surveyed 97 college football student-athletes and conducted interviews with athletic administrators. Key findings revealed a moderately positive correlation (r=.340, p<.001) between administrative support and student-athlete knowledge of NIL policies, demonstrating that institutional investment in educational support directly impacts policy comprehension. The research found that 67% of student-athletes indicated NIL opportunities would influence their school choice decisions, fundamentally altering recruitment dynamics. Additionally, 57.7% of participants agreed that NIL affects team culture, though responses indicated this impact is highly contextual and dependent on institutional management. The study identified significant variation in educational leadership approaches across institutions, with some employing dedicated NIL strategy teams while others integrate responsibilities within existing compliance departments. A notable gap emerged between student-athlete NIL expectations and institutional support, with many athletes reporting they "do everything on our own." For higher education institutions, findings suggest the need for comprehensive NIL education programs extending beyond basic compliance to include financial literacy, contract negotiation, and personal branding. Institutions should develop values-based frameworks aligning NIL opportunities with institutional missions while protecting student-athlete interests. The research contributes valuable insights for navigating the evolving NIL landscape while supporting student-athlete success.

Cross-Domain Transfer Learning Of Tabular Data With Heterogeneous Feature Spaces, Kazi Fuad Bin Akhter Dec 2025

Cross-Domain Transfer Learning Of Tabular Data With Heterogeneous Feature Spaces, Kazi Fuad Bin Akhter

Tennessee State University Alumni Theses and Dissertations

Transfer learning is a cornerstone of artificial intelligence (AI), enabling the learning of new domains with limited labeled data by reusing knowledge from large-scale foundation models. Transfer learning has achieved remarkable success with vision and language models due to the homogeneity in image and text data. In contrast, a heterogeneous feature space, structured in rows and columns as tabular data, remains underexplored in the transfer-learning literature. The inductive bias of tabular data with heterogeneous feature spaces from disparate application domains is very different from image and text data, which complicates transfer learning. Several recent studies have attempted within-domain and limited …

Privacy-Preserving Data Sharing For Learnable Encryption Artificial Intelligence In E-Health, Al Amin Dec 2025

Privacy-Preserving Data Sharing For Learnable Encryption Artificial Intelligence In E-Health, Al Amin

Tennessee State University Alumni Theses and Dissertations

Healthcare AI requires large datasets for clinical-grade performance, yet privacy regulations prevent direct inter-institutional data sharing. While traditional federated learning (FL) enables collaborative training without centralizing data, it suffers from four critical limitations: accuracy degradation, gradient leakage vulnerabilities, high communication costs, and limited interpretability. Accordingly, the overarching research goal is to design a privacy-first FL framework for e-health that preserves clinical-grade accuracy on obfuscated data while substantially reducing information leakage, minimizing communication overhead, and enabling interpretable decision support without sharing weights, gradients, or raw pixels. This thesis systematically addresses these challenges through a three-method framework that progressively enhances privacy, efficiency, …
