The Impact Of The Two-Way Immersion Model On Hispanic Pre-Service And In-Service Teachers’ Understanding Of Curriculum Implementation In Early Childhood Field Placements, Omar J. Vigo

LSU Doctoral Dissertations

ABSTRACT

Dual language education, also known as Two-Way Immersion (TWI), is a teaching method that puts native English speakers and native speakers of another language in the same classroom. This helps both groups become bilingual and biliterate (Christian, 1996; Lindholm-Leary, 2001). The TWI approach highlights several benefits, including bilingualism and biliteracy, academic achievement, cross-cultural competence, cognitive improvements, and equity and accessibility (Lindholm-Leary, 2001). Research on the TWI model in adults is limited, although it has demonstrated effectiveness in supporting Hispanic teacher candidates, unlike studies conducted in primary education. This demonstrates that the TWI methodology benefits students (Van Booven, 2012). This …

Algebraic Invariants Of Multi-Virtual Links, Louis H. Kauffman, Sujoy Mukherjee, Petr Vojtěchovský

Mathematics: Faculty Scholarship

Multi-virtual knot theory was introduced in 2024 by the first author. In this paper, we initiate the study of algebraic invariants of multi-virtual links. After determining a generating set of (oriented) multi-virtual Reidemeister moves, we discuss the equivalence of multi-virtual link diagrams, particularly those that have the same virtual projections. We introduce operator quandles (that is, quandles with a list of pairwise commuting automorphisms) and construct an infinite family of connected operator quandles in which at least one third of right translations are distinct and pairwise commute. Using our set of generating moves, we establish the operator quandle coloring invariant …

What Is The Contribution Of Thermal Selection To The Maintenance Of A Shell Color Cline In Littorina Saxatilis?, Ramón Vigo, Sarah L.Y. Lau, Juan Gefaell, Juan Galindo, Gray A. Williams, Manuela Truebano, Emilio Rolán-Alvarez

School of Biological and Marine Sciences

The study of clines, or geographical variations of a given trait, can help understand how the interactions of genetics and local environments determine phenotypic diversity. The marine snail Littorina saxatilis (Olivi, 1792) exhibits a gradual change in the relative frequencies of shell color morphs across populations in the estuary system of the Rias Baixas (Galicia, NW Iberian Peninsula). A consistent pattern of distribution occurs across these four Rias, with the interior, sheltered regions dominated by a light fawn-like morph (fulva), and the exterior, wave-exposed locations by a darker lineated morph (lineata). Measurements of rock surface temperature along one of the …

Secure Machine Learning In Networking Systems, Wenwei Zhao

USF Tampa Graduate Theses and Dissertations

With the rapid integration of Machine Learning (ML) into networking systems, ensuring the security and trustworthiness of these intelligent frameworks has become a paramount concern. While ML offers unprecedented capabilities in spectrum management and collaborative learning, it also introduces novel vulnerabilities that can be exploited by sophisticated adversaries. This dissertation investigates and addresses critical security challenges across three key dimensions of ML-driven networking: adversarial spectrum sensing, the security of privacy-preserving unlearning processes, and efficient post-attack model recovery.

First, we address the threat of adversarial spectrum attacks in cognitive radio networks, where malicious nodes manipulate sensing reports to disrupt spectrum access. …

Critical Discourse Analysis Of Turnaround Leadership Competencies Using A Transformative Leadership Framework, Kevin D. Mcdonald

USF Tampa Graduate Theses and Dissertations

School turnaround leadership has become a leading strategy to address school underperformance emphasizing rapid and dramatic improvement in a school within the bottom five percent of schools as measured by gains in both mathematics and English Language Arts. However, prevailing turnaround leadership discourse largely centers technical and managerial competencies, often marginalizing leadership practices oriented toward equity, advocacy, and social transformation. This narrowing of leadership is particularly consequential for Black male principals, who are disproportionately assigned to low-performing and turnaround schools and whose leadership practice frequently reflects core elements of transformative leadership.

The purpose of this dissertation was to explore current …

Hybrid Neural Network Model Defenses, Eric Yocam

Dissertations

Hybrid neural networks (HNNs), which integrate classical convolutional neural networks with quantum circuit components, are highly vulnerable to white-box targeted compound (WTC) adversarial attacks. Previous research has primarily evaluated defenses against single-method attacks, leaving a critical gap in understanding defense effectiveness against compound attacks that combine multiple perturbation strategies. This research study systematically evaluates defense mechanisms against WTC adversarial attacks on HNN models across 120 experimental conditions. Three defense categories are investigated: test-time defenses (input transformation and randomization, applied during inference without retraining) and training-time defense (adversarial training, requiring model retraining). Evaluation uses four datasets (MNIST, EMNIST "Digits", TinyImageNet, TrafficSigns) …

Extending The Geometric Phase To Relativistic Spacetime, Sajid Raihan Akash

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

The Berry phase [3] is traditionally understood as a geometric phase acquired during cyclic adiabatic evolution, often interpreted as the flux of an effective “magnetic field” through a solid angle in parameter space. In this thesis, we investigate situations in which a geometric phase arises even when no spatial solid angle is enclosed, revealing the limitations of the standard purely spatial interpretation. We first review the Berry phase for a spin-½ particle in a slowly varying magnetic field and analyze scenarios in which the system’s eigenstate is changed during the adiabatic evolution. We show that the resulting phase can be …

Mould Risk Prevention In Healthcare Facilities In Hot And Humid Climates Through Acmv Air Supply Parameter Optimisation: Development And Validation Of A Multi-Objective Optimisation Framework, Jiang Kaiyun

Student Works (2020-2029)

Air conditioning mechanical ventilation (ACMV) supply parameters—such as airflow rate, temperature, and humidity—significantly influence indoor thermal and hygrometric conditions, influencing airflow patterns and mould proliferation. In healthcare facilities, mould poses significant health risks, particularly for immunocompromised patients, contributing to respiratory issues, allergic reactions, and infections. While ACMV systems are central to infection control and indoor air quality, conventional designs often fall short in hot and humid climates. Existing practices typically prioritise high air change rates (ACH) without sufficient dehumidification, underestimate humidity control, and assume spatial homogeneity, overlooking microclimates conducive to localised mould growth. To address these limitations, this research develops …
