Security Architecture Decision Framework For Endpoint Protection In Resource-Constrained K-12 Environments, Jason Folker

Journal of Cybersecurity Education, Research and Practice

K-12 educational institutions face an ongoing challenge in protecting endpoints when budgets and staffing prevent the implementation of standard security best practices. Technology directors routinely make difficult decisions about administrative rights, software controls, and security tooling, but they lack frameworks designed for the constraints and priorities specific to educational environments. This paper develops a security architecture decision framework tailored for K-12 endpoint protection. The framework integrates five weighting dimensions to help technology directors evaluate competing architectural choices. These dimensions include educational impact, security risk reduction, resource requirements, compliance obligations, and operational feasibility. The framework creates structured documentation that helps decision-makers …

Electrospinning Of Covalent Organic Frameworks (Cofs) For Adsorption Of Heavy Metal Ions, Samar A. Salim

Nanotechnology Research Centre

This study reported the synthesis, electrospinning, and heavy metal adsorption of covalent organic frameworks (COFs) integrated into poly(methyl methacrylate) (PMMA) nanofibers. COF-1 and COF-2 were synthesized by solvothermal and reflux techniques, respectively, and subsequently incorporated into PMMA via electrospinning with different loadings (0.1%, 0.5%, and 1.0%). The synthesized PMMA_COF nanofibers were analyzed utilizing X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and diffuse reflectance spectroscopy (DRS). PMMA_COF nanofibers with fiber diameters of 350-450 nm were obtained. The structural and morphological investigations validated the effective integration of COFs into the PMMA matrix, with COF-1 demonstrating superior dispersion …

Pseudodifferential Absorbing Boundary Conditions For Waves, Lauren Taylor

Mechanical Engineering Theses

Absorbing boundary conditions (ABCs) are required to truncate the computational domain when performing Finite Element Analyses of exterior acoustic problems where physical domain is unbounded. ABC is applied on a fictitious boundary containing the scatterer and ideally allows outgoing waves to leave without non-physical reflections. Preventing artificial reflections is essential to benefit from the accuracy of the numerical method used. Otherwise, ABC acts as a reflective surface, and artificial reflections distort the solution in the entire domain which is not recoverable by any type of refinement. Pseudodifferential ABCs were used to describe the Dirichlet-to-Neumann map which maps known boundary values …

Biophysical Insights Into A Cryptic Ligand Site In The Hydrophobic Core Of Human Pcna, Alexis N. Dispensa, Sharon N, Greenwood, Jason Yang, Daniel E. Logatto, James Fusco, E. Railey White, Roderic G. Eckenhoff, Zhiwei Liu, Brian P. Weiser

Department of Anesthesiology Faculty Papers

Proteins contain small pockets that form due to imperfections in residue packing or the rotational and conformational movement of amino acids. In this work, we used the fluorescent probe 1-aminoanthracene (AMA) to detect a small ligand pocket in the hydrophobic core of human proliferating cell nuclear antigen (PCNA), which is a critical protein for DNA replication and repair. Fluorescence measurements of AMA reported that the core of PCNA had a dielectric constant (ε) of 4, which was very apolar and similar to cyclohexane (ε = 2). Protein mutagenesis, photoaffinity labeling, and molecular dynamics simulations localized the binding site for AMA …

Sleep Disturbances Affect Sleep Quality Of Hospitalized Adults, Tonjia Hardesty

Dissertations

Abstract

Background: Sleep disturbances affect the quality of sleep hospitalized adults experience, possibly extending patient recovery time. Treatment of insomnia frequently includes pharmacological interventions exposing patients to potential side effects, leading to negative patient outcomes.  The purpose of this project was to determine if a sleep hygiene toolkit including eye masks, earplugs, advocacy cards, and removal of nicotine patches at bedtime would improve patient sleep quality without use of pharmacological interventions.

Methods: A descriptive observational design was used in this quality improvement (QI) project. A convenience sample of 37 (N =37) participants over the age of 18 years and …

Enhancing Well-Being: Implementing Weekly Social Interventions For Older Adults In Independent Living, Rosa Huang

Dissertations

Loneliness and social isolation significantly impact the physical and mental well-being of older adults. This quality improvement project implemented an eight-week social intervention designed to reduce loneliness and enhance well-being through weekly sessions incorporating mindfulness exercises, gratitude journaling, and structured socialization activities. The intervention was delivered by nursing students to a sample of residents in a Midwestern independent living community. While most standardized measures of loneliness and mood did not show statistically significant changes, the project resulted in a statistically significant increase in social network engagement as measured by the Lubben Social Network Scale-6 (LSNS-6). The findings suggest that group-based …

Extrafloral Nectaries In Woody Plants: Toward An Integrated Framework For Ant-Mediated Plant Defense, Fangming Liu, Qifei Cai, Victor Busov, Zhen Liu

Michigan Tech Publications

Extrafloral nectaries (EFNs)-secretory structures that recruit predatory arthropods as indirect defenders against herbivory-have been studied almost exclusively in herbaceous systems, leaving a critical gap in our understanding of plant defense in woody plants. In trees, secondary growth, ontogenetic regulation, and seasonal phenology generate structural and temporal heterogeneity in EFN expression poorly captured by existing frameworks. We synthesize evidence across structural, chemical, and functional dimensions of EFN biology to develop an integrated framework for perennial trees. Our analysis suggests that methodological limitations in EFN detection likely bias the current chemical record of woody EFNs, while incomplete chemical characterization constrains the evaluation …

Coherent Two-Photon Backscattering And Induced Angular Quantum Correlations In Multiple-Scattered Two-Photon States Of The Light, Nooshin M. Estakhri, Theodore B. Norris

Engineering Faculty Articles and Research

We present the emergence of coherent two-photon backscattering, a manifestation of weak localization, in multiple scattering of maximally entangled pure and fully mixed two-photon states and examine the effect of entanglement and classical correlations. Quantum correlations in backscattering are investigated for finite three-dimensional disordered structures in the weak localization regime, as well as systems of a small number of scatterers with specified spatial arrangements. No assumptions are made about the statistical behavior of the scattering matrix elements. Furthermore, we study the interplay between quantum correlations induced by multiple scattering and the correlations that may be present in the illumination fields, …

Nanoscale Morphological Perturbations Of Lipid Membranes Induced By Membrane Active Peptides, Yasith Sandeepa Indigahawela Gamage

USF Tampa Graduate Theses and Dissertations

Membrane-active peptides (MAPs) are a diverse group of biologically relevant molecules that induce nanoscale modulations during their interactions with cell membranes. Understanding the precise mechanism by which these MAPs perturb or modulate the cell membranes is a cornerstone of membrane biophysics, as it facilitates rational design of useful therapeutics. That is, if we have the knowledge to determine what the peptide can do, how selective it is, or how toxic it might be, we can optimize them and design new peptide therapeutics such as for antimicrobial, anticancer, or drug-delivery applications. In general, MAPs can be categorized into two classes based …

Sensitivity Analysis Of A Line-Scan Hyperspectral Camera For Single-Channel Ifld-Based Solar Induced Fluorescence Retrieval And Early Nitrogen Stress Detection In Cotton, Angelin Regina Maria Villanueva Favorito

Electronic Theses and Dissertations Archive

Nitrogen (N) deficiency is a significant contributor to crop stress and yield loss in cotton, yet early detection remains challenging because conventional vegetation indices such as NDVI only resolve physiological changes after prolonged stress has produced outward structural symptoms. Solar-induced chlorophyll fluorescence (SIF), estimated via the improved Fraunhofer Line Depth (iFLD) method, offers a functional indicator of photosynthetic activity that responds to stress before structural changes emerge. This thesis presents two studies investigating the use of a single-channel line-scan hyperspectral camera for proximal SIF retrieval and its application to early N-stress detection in cotton. Study I demonstrated that an in-scene …

Defensive Publications Series

Evaluating personalized artificial intelligence (AI) systems may be challenging, as the use of detailed user context can conflict with user privacy considerations. A system is described for generating synthetic user populations via a world simulation. The system can create generative agents with demographic and behavioral characteristics based on aggregated, anonymized statistical data. These agents can interact over time within a simulated environment, producing a stream of longitudinal user behavior captured in isolated test accounts. The resulting dataset can be used for scalable, automated testing and debugging of AI models, offering a contextually rich, privacy-respecting alternative to using real user data. …

Agent-Aware Mesh Network For Hybrid Ai Policy Enforcement, Antonio Ojea

Defensive Publications Series

Beyond The Romance Of Leadership: Shackleton, Self-Inflicted Crisis, And The Values Of Recovery, Carl Lee Tolbert

The Journal of Values-Based Leadership

Two men answered to the name Ernest Shackleton. One belonged to the ice, where he was pioneering, inspirational, and heroic. The other belonged to dry land, where he was restless, indebted, and unfulfilled (Smith, 2014). The 1914 to 1916 Endurance expedition has become the most celebrated leadership case study of the past century, a status the 2022 discovery of the ship's preserved wreck has only hardened. Public and scholarly sentiment runs overwhelmingly positive. This article reads that sentiment as a late expression of what Meindl and colleagues named the Romance of Leadership, the disposition to attribute outcomes to dramatic individual …

A Person For All Seasons: The Remarkable Leadership Of Mother Cabrini And Why It Matters Today, Emilio F. Iodice

The Journal of Values-Based Leadership

The history of organizational management is often written in the bold, sweeping strokes of industrial barons or the calculated maneuvers of political statesmen. Yet at the turn of the twentieth century, one of the most sophisticated examples of global institutional scaling was orchestrated by a woman who stood barely five feet tall, held no formal political title, and suffered from debilitating physical frailty. Frances Xavier Cabrini (1850–1917) did not merely practice charity; she engineered a global revolution of care. Over a twenty-eight-year executive career, she founded sixty-seven schools, orphanages, and hospitals across three continents, thereby transforming the social landscape of …

Student Perspectives On Professionalism In The Academic Classroom: Examining Instructor Traits And Student Preferences At A U.S. Service Academy, Jason Lackey, Justin White

The Journal of Values-Based Leadership

At the US Air Force Academy, student developmental paths occur under both military and academic components. The academic component includes the typical collegiate coursework taught by a combination of civilian and military instructors. In this study, we explored student values of instructor leadership traits and practices that influence the classroom culture. We found that overall, the instructor’s degree of academic knowledge (distinguished from military knowledge), their ability to clearly communicate class content, and ability to inspire student participation ranked highest. Conversely, the instructor clearly communicating military responsibilities, their professional etiquette, and providing constructive feedback pertaining to military bearing ranked least, …

The Character Fractal: A Theory Of Virtue Replication In Organizations, Kevin Davis, Scott Kozlak, Matthew M. Orlowsky, David Levy

The Journal of Values-Based Leadership

Organizational ethics has long been treated as an individual problem requiring individual solutions: the right traits, the right training, the right people in the right roles. This paper argues that framing is fundamentally insufficient. While character and virtue ultimately reside in persons, character development within organizations emerges through recursive ethical interactions shaped by incentives, narratives, feedback loops, and habituation structures cultivated by systems leaders. It replicates, or fails to, across every scale of human interaction, from the unobserved micro-decision of a single employee to the macro-level architecture of executive leadership. Drawing on Mandelbrot's fractal geometry, Lorenz's chaos theory, Kauffman's complexity …

The Culture Metaphor: A Simple Guide To Creating Healthier Organizations, Matthew I. Horner, T. Daniel White, Rylan M. Charlton, Daphne Ds Deporres

The Journal of Values-Based Leadership

In this paper, culture is conceptualized as a living system where every organizational decision and interpersonal interaction is a source of nourishment. Employing this metaphor, a leader’s visible actions, such as policy and resource decisions, serve as macronutrients, while exchanges between organizational members, such as email correspondence and meeting behavior, act as micronutrients that feed culture. An organization’s cultural health, therefore, depends on a balanced diet in which behaviors align with stated values. Leaders, as chief dietitians, identify and resolve deficiencies to build trust, enhance well-being, and improve performance. Actionable strategies for diagnosing and feeding culture are provided to help …
