Discerning The Role Of Microtubule Acetylation During Hiv-1 Infection, Drew Michael Lichon

Dissertations

The host-pathogen interactions underlying Human Immunodeficiency Virus type 1 (HIV-1) infection are complex and involve the exploitation of host cellular machinery. This thesis investigates the roles of dynein adaptors, microtubule acetylation, and TRIM69-mediated restriction in HIV-1 infection. Through a series of detailed experiments, we explore how HIV-1 utilizes multiple dynein adaptors, such as BICDR1 and Hook3, for intracellular transport, and reveal that these adaptors are critical for efficient viral trafficking. Conversely, the knockdown of Ninein surprisingly enhances HIV-1 infectivity, suggesting a nuanced regulatory role for this adaptor in viral transport. Further, this thesis challenges the prevailing paradigm that microtubule acetylation …

Catholic parish life in the United States has passed the point of decline where minor changes will enable it to grow again. Church leaders need a new missionary culture and outward-focused approaches to reach people today with the timeless truths of the faith. The old mindset of putting all the responsibility on the shoulders of the clergy to solve problems no longer works. Since heterogeneous groups make better decisions than homogeneous groups in complex, adaptive situations, this study explores the hypothesis that inclusive leadership by Catholic parish leaders leads to more innovation and better solutions to the challenges of church …

Insights Into Female Urinary Microbiota Through Long-Read 16s Rrna Sequencing, Jerrin John

Dissertations

The human urinary microbiome—once thought to be sterile—is now recognized as a dynamic, low-biomass microbial community with potential implications for urinary tract health. Conventional short-read 16S rRNA gene sequencing targeting individual variable regions often lacks the taxonomic resolution needed to distinguish closely related species, while culture-based methods may miss fastidious or low-abundance taxa. We applied full-length 16S rRNA gene sequencing across all nine variable regions to daily urine samples collected from asymptomatic premenopausal female participants. Sequence data were processed with a modified DADA2 pipeline optimized for long reads to generate exact sequence variants. We compared species-level community profiles against both …

Skip-Level Meetings: Perspectives Of Skipped First-Tier U.S. Tech Leaders, Samuel Blacher

Dissertations

Although significant research exists on numerous intersecting theories, such as adaptive leadership, leadership communication, and employee voice, and although they are discussed in business publications and widely yet inconsistently implemented in industry, skip-level meetings are little scholarly studied. Such meetings offer benefits for employees, direct (skipped) managers, and skip-level leaders, and through them, to organizations, yet they also hold risks and pitfalls, and are influenced by various contextual factors, such as stakeholders’ national culture and age. This exploratory qualitative study employed elements of interpretive phenomenology, followed by thematic analysis, to examine the experiences, perceptions, and emotions of a diverse set …

Data were collected through semi-structured interviews and analyzed through descriptive and iterative coding. Codes were grouped into broader categories, resulting in five emerging themes: voiceless calling, bound to tradition, call from …

Shattering The Glass Ceiling, Navigating The Glass Cliffs: A Case Study Of Andrea Luxton As The First Woman President Of Andrews University (2016-2023), Maureen Sakshi Pakalahati

Dissertations

Problems

Research shows glass ceilings are thicker in faith-based institutions heavily governed by traditional beliefs and dominated by men. Research also shows singlism is on the rise in churches. There is limited research on the lived experiences of single, never married woman who reached the presidency (shattering the glass ceiling) in a faith-based institution. Leadership pundits predict a “great resignation”, which is an era of high presidential turnover, due to mounting challenges in the higher education presidency. Great resignation is a gender-neutral phenomenon, but women presidents are subject to stern criticism and penalties, leading to more disproportionate resignations. Furthermore, the …

Characterizing Niche Specialization In Staphylococcus Epidermidis, Sandra Jablonsk

Dissertations

This thesis investigates the microbial diversity of Staphylococcus epidermidis (S. epidermidis) across various anatomical sites in the human body. While traditionally viewed as a benign skin microbe, S. epidermidis also inhabits the urinary, gastrointestinal, and respiratory tracts, raising questions about its genetic variation and adaptability in different environments. The research aims to compare strains of S. epidermidis isolated from the oral cavity, nostrils, urinary tract, and skin of healthy individuals to determine if they share a common ancestor or if they evolved independently in response to specific environmental factors. The study comprises three main aims. Aim 1 focuses on assessing …

Examining Pyroptosis In Neutrophil-Like Differentiated Hl-60 Cells, Jared Long

Dissertations

The innate immune system is the first line of defense against pathogens. Innate immune cells, such as macrophages and neutrophils, recognize pathogens through the recognition of pathogen associated molecular patterns or damage associated molecular patterns (PAMPS & DAMPS). When a pathogen is recognized, innate immune cells will start clearing the pathogen and secreting pro-inflammatory cytokines, such as interleukin-1β (IL-1β) to initiate the innate immune response. Release of IL-1β occurs through an unconventional secretory pathway triggered by inflammasome activation. Activation of the NLR family pyrin domain containing 3 (NLRP3) inflammasome cleaves both pro-IL-1β into mature IL-1β, and full length gasdermin-D (GSDMD) …

Directed Assembly Of Magnetic Binary Suspensions, David H. Harris

Dissertations

Colloids are particle suspensions in a continuous medium. The particle interactions promote the assembly of structures under the influence of a magnetic field, known as directed-assembly. The magnetic properties and shape anisotropy are relevant features of the particle building blocks to the assembled structures. The dipolar interaction between colloidal particles for directed assembly has been extensively modeled considering spherical particle potentials, which is inaccurate when anisotropic particles are at close range. This research aims to address the problem of quantifying the dipolar interaction between arbitrarily positioned and oriented ellipsoids with different aspect ratios and material properties. We combine the recently …

Correlating Optical Phase And Atmospheric Coherence Width In Characterizing Turbulence, Scott Alexander Kaiser

Dissertations

This dissertation presents the development, validation, and optimization of a novel Hartmann Turbulence Sensor (HTS) for real-time, high-speed characterization of atmospheric optical turbulence. The HTS captures and processes live data at 1 kHz and reports turbulence parameters at 22 Hz. A key innovation is the integration of a dominant spectral component selection method into the Difference in Differential Tilt Variance (DDTV) algorithm. By using spectral analysis to identify areas of interest (AOIs) based on their dominant spatial frequency content, this method reduces computational load by up to 75% while maintaining a low RMS error. It also offers a visual representation …

Assessing The Selection And Impact Of Completeness In Technical Measure Sets In Systems Engineering, Casey Eaton

Dissertations

Technical measurement is foundational in large-scale complex engineered systems (LSCES) design and contract awards due to the state of practice of systems engineering. Although technical measurement is ubiquitous in systems engineering practice, the selection and assessment of the impact of a set of technical measures is often heuristics-based, rather than based on empirical evidence or theory. Current technical measure set selection has been observed to be subject to many challenges which, in turn, can degrade system outcomes. Two main thrusts comprise the research: selection and impact. Motivated by the potential impacts of a poor set of technical measures, a significant …

Nonlinear Vortical Electron Acceleration In Magnetic Reconnection And Its Application To Solar Flares, Christopher Crawford

Dissertations

The origin of solar energetic electrons has been a long-standing problem, namely the production of a huge number of energetic electrons with power-law energy spectra within a sufficiently short time. Using particle-in-cell (PIC) magnetic reconnection (MR) simulations based on a new vortical electron acceleration model proposed by Che and Zank (CZ) [21], I first investigated the scaling of the PIC MR simulations to the observational scales of solar flares. The CZ model reproduced the sharp two-stage transition observed in soft-hard-harder electron energy spectra, implying that the electron acceleration timescale must be a small fraction of the solar flare duration. Then …

A Rubber-Band System For Dynamic Incentivization Of Parallelized Gamified Objectives, Nicholas Diliberti

Dissertations

With the advent of videogames as the world's first mass-market interactive media, gamification has emerged as the premier way to harness powerful behavior-affecting gamified elements and place them in other contexts, such as education, fitness, and rehabilitation. This transposition, however, ignores a key tenant of user engagement: reward ought to be aligned with effort. Most, if not all, current gamification systems dispatch static reward allocations for their spread of gamified behaviors. In this paper, an alternative is presented: dynamic gamification. This dynamic gamification reads the user's current gamified state for indicators of aptitude, dynamically remaps rewards with a tuneable evaluation …

The Impact Of Professionalism Education And Formative Feedback In Doctor Of Physical Therapy Students Utilizing The Abbreviated Cpi Feedback Form In The On-Campus Clinic Environment, William L. Scott

Dissertations

Problem

The American Physical Therapy Association (APTA) developed the Clinical Performance Instrument (CPI) to assess the professional behaviors required for a Doctor of Physical Therapy (DPT) student to be considered "entry level" in their clinical training. Feedback from our clinical partners has indicated that, historically, students from the Andrews University DPT program have scored lower than students from other programs in several areas of the CPI during their clinical experiences. According to subjective reports from our clinical partners, these areas included safety, professional behavior, accountability, communication, and critical thinking. These five areas have been the focus of our efforts in …

Moral Identity And Its Relationship To Higher Education Mentoring And Community Service Engagement, Maria O. Rodriguez

Dissertations

Problem

A moral action is a result of the engagement of multiple psychological processes set in motion when an individual faces a moral conflict. Research suggests that an individual's moral reasoning and moral identity strongly influence the psychological processes that precede a moral action. Recent studies have shown that higher education positively influences students' moral reasoning; however, there is a lack of understanding as to the degree to which higher education can influence the moral identity of students.

Method

This study performed a quantitative cross-sectional study to investigate the relationship between independent variables—mentoring experiences and community service engagement—and dependent variables—moral …
