The findings show significant improvements in inclusive classroom practices, gender-sensitive pedagogy, and teacher confidence, especially when reflective peer learning and continuous mentoring are incorporated. Children’s academic performance and well-being have been linked to the integration …

A Multi-Criteria Decision And Spatial Modeling Framework For Socially Informed Advanced Air Mobility Implementation Planning, Noah Wesley Bretz

Graduate Theses and Dissertations

Advanced air mobility (AAM) is an emerging mode of transportation that integrates advanced aircraft technologies, such as manned air taxis or unmanned freight drones, to transport people and goods across urban and regional environments. While these technologies promise to transform mobility, successful implementation depends heavily on community acceptance, which is shaped by multiple social factors. This study presents a multi-criteria decision framework to evaluate and prioritize the key social factors influencing AAM adoption. A literature review identified six primary social factors: safety, noise, privacy and cybersecurity, automation, environmental impact, and price and economics. The Analytical Hierarchy Process (AHP) was used …

Evaluating Bawaslu’S Sigaplapor For Electoral Justice In Indonesia’S 2024 Election, Nur Hidayat Sardini, Muhtar Muhtar

Jurnal Wacana Politik

This article assesses the effectiveness of the Election Violation Handling and Reporting Information System (SiGapLapor) operated by Indonesia’s Election Supervisory Body (Bawaslu) as a case of digitalising electoral oversight. Using a qualitative-exploratory case study, the research draws on document analysis (regulations, internal reports, and SiGapLapor web statistics) and semi-structured interviews and focus group discussions with election supervisors and ICT managers. Findings indicate that SiGapLapor works reasonably well as an administrative registry and an internal reporting tool, but remains weak as a participatory public complaints mechanism and as an instrument of electoral justice. Key constraints include a non-user-centred interface, predominantly manual …

Recruitment Of Chrysaora Chesapeakei On Floating Docks Versus Bulkhead Surfaces: Which Axis Is Foulset?, Alyssa Lamberto

Theses, Dissertations and Culminating Projects

Blooms of Chrysaora chesapeakei (bay nettles) have increased sharply in Barnegat Bay, New Jersey, reducing both ecological integrity and economic value. Because population expansion is driven primarily by the benthic polyp stage, where individuals attach to hard substrates and reproduce asexually, effective management must target the surfaces where polyps settle and clone themselves. The rapid growth of artificial infrastructure, particularly vinyl docks and bulkheads, has expanded available habitat for polyp recruitment. Scrubbing these structures has been shown to reduce ephyrae production, but it remains unclear whether both docks and bulkheads warrant equal management attention. This study compared recruitment on horizontal …

Individual Recognition: Do Horned Passalus, Odontotaenius Disjunctus, Display Individual Discrimination Of Familiar And Unfamiliar Conspecifics Through Changes In Their Behavior?, Sabrina Galloza

Theses, Dissertations and Culminating Projects

The horned passalus, Odontotaenius disjunctus, are subsocial beetles that inhabit and defend decaying wood where they create galleries to live, mate, breed and provide brood care. The species is well known for their stridulations, making up to 14 different sounds, having one of the greatest repertoire of sounds for any known arthropod. Typically living in family units, it has been found that several families can inhabit the same log, therefore, the horned passalus can come into contact with both kin and non-kin. It is currently unknown whether the horned passalus can distinguish between nestmates and non-nestmates. Additionally, it is unknown …

The Impact Of Community On Professional Identity In Computer Science Education, Ian A. Kollipara

School of Computing: Dissertations, Theses, and Student Research

This thesis explores the application of Communities of Practice (CoPs) in Computer Science Education. The work consists of two qualitative studies examining related but distinct populations: (1) K–12 CS teachers and (2) undergraduate CS students. The first study presents a retrospective analysis of conneCTION, an online CoP for K–12 CS educators, identifying strengths, weaknesses, and design considerations that inform future platform development. The second study investigates how participation in a CoP can mitigate negative and exclusionary stereotypes in CS. This study was conducted in an under-explored context: a small, private, religious, Midwestern university, and examines an existing community, the Programming …

Experimental Data-Driven System Identification Of Scale-Model Airboat Dynamics For Control And Autonomy Applications, Miguel A. Trejos

LSU New Orleans Theses and Dissertations

To achieve autonomous control of a surface watercraft requires an accurate model describing the dynamics of the system. To this end, the modeling of dynamics of an airboat with a combustion engine-based propulsion system is investigated. Specifically, a black-box data-based approach using neural networks. To facilitate this, a custom data collection system was developed to record linear and rotational motion during field tests. Due to the airboats unique ability to traverse different terrains, not just water, the modeling of dynamics on different terrains was investigated.

Careers That Feel Like Plinko And A Labor Of Love: A Phenomenology Of Full-Time Contingent Faculty’S Development As Instructors At A University In Transition, Anne Ogburn

LSU New Orleans Theses and Dissertations

Instructors in higher education often do not study or practice teaching before entering the classroom (Flaherty, 2019; McMurtie, 2021). Instead, instructors may develop their teaching knowledge and skills in a variety of ways (Hora & Smolarek, 2018; Kennedy, 2016; McCrickerd, 2012; Oleson & Hora, 2014). Despite this haphazard approach, instructor development is particularly important in higher education given that effective teaching practices improve success outcomes for students (Kilgo et al., 2015; Loes et al., 2019; Umbach & Wawrzynski, 2005). Researchers have focused on the impact of introductory courses on students’ long-term success in a given subject or major (Xu, 2019). …

Advancement In Electrochemical Generation-Collection: Snapshot Redox Cycling Voltammetry For Rapid Analysis At Chip-Based, Individually Addressable Microband Electrode Arrays, Blake Aleck Sterling

Graduate Theses and Dissertations

Snapshot redox cycling voltammetry (Snapshot RCV) is introduced as a rapid electrochemical technique that reconstructs the current-potential profile of a redox active species using a microband electrode array. By simultaneously biasing individual generator electrodes alternating in the array to different voltages across the analyte’s potential range while individually holding collector electrodes at a reversing potential, “spatial” voltammetry is achieved in as little as 1 s with the temporal speed of chronoamperometry, rapidly capturing the steady-state redox cycling (RC) profiles. During RC (a mode of generation-collection), the analyte is oxidized (or reduced) at generator electrodes and converted back at neighboring collector …

Explainability In Deep Learning For Density Regression, Dalton James Oxford

Graduate Theses and Dissertations

Classical statistical methods focus on explainability and inferential power. Machine learning and deep learning can handle non-linear, high-dimensional data better than traditional methods. In modeling, a clear understanding and interpretation are essential to decision-making. Recent work in quantile regression and extreme modeling has begun to use deep learning due to its performance on high-dimensional, non-linear data. Semi-Parametric Quantile Regression (SPQR) is a nonparametric spline-based approach to quantile regression that estimates the conditional PDF and CDF of the response. Semi-Parametric Quantile Regression for Extremes (SPQRx) is a recent extension of SPQR that provides two features: out-of-sample estimation and accurate extreme-tailed estimation. …

Strain Engineering Of Excitonic And Vibrational Properties In Two-Dimensional Transition Metal Dichalcogenides, Sneha Minesh Patel

Graduate Theses and Dissertations

Mechanical strain represents a robust and non-invasive method for tuning the electronic and vibrational properties of two-dimensional transition-metal dichalcogenides (TMDs). This work examines homogeneous biaxial strain as a symmetry-preserving control parameter that governs excitonic and interlayer dynamics in atomically thin TMDs. In monolayer MoSe2, biaxial tensile strain is intrinsically generated during high-temperature physical vapor deposition due to thermal expansion mismatch with amorphous substrates. Optical spectroscopy demonstrates substantial and tunable excitonic energy shifts exceeding 100 meV per percent strain. Polarization-resolved second harmonic generation confirms the retention of lattice symmetry under biaxial deformation. The investigation is further extended to bilayer MoS2, where …

Orbital Rendezvous In Schwarzschild Spacetime, Joaquin Malarria

Theses & ETDs

This thesis develops a relativistic generalization of the classical Hohmann transfer between circular orbits in a central gravitational field. The problem is formulated in Schwarzschild spacetime, where spacecraft trajectories are modeled as timelike geodesics and orbital transfers as sequences of impulsive velocity changes. Using conserved quantities derived from Killing vectors, the equations of motion are reduced to an effective radial problem, allowing the construction of bound transfer orbits connecting two circular orbits. A parametric representation of the radial motion is used to evaluate the azimuthal advance and time of flight along the transfer trajectory, with numerical methods used where closed-form …

Bumblebee Fields In A Schwarzschild Background, Demetre Seturidze

Theses & ETDs

In this thesis, we investigate the behavior of a Lorentz-violating vector field near an uncharged static black hole. We analyze the equilibrium configuration of the field and its linear perturbations. We show that the equilibrium solution and spherically symmetric perturbations are governed by a quadratic function whose properties determine their qualitative behavior. By imposing realness and convergence, we derive bounds on the allowed parameters and identify a critical case in which the monopole perturbations grow large. We further derive asymptotic expressions for multipole perturbations near the event horizon and spatial infinity

Flipping The Format: A Comparative Analysis Of Pedagogy’S Performance On Comprehension In Introductory Financial Accounting Education, Allison Drozd

Theses/Capstones/Creative Projects

Education is an ever-evolving field, and accounting education is no different. Introductory financial accounting is a required business course at universities that is characterized by high failure rates (Kealey et al., 2005). Evidence suggests that active learning and constructivist approaches improve comprehension of introductory financial accounting concepts as measured by exam performance. All methods studied produced statistically significant positive results on comprehension learning outcomes. Many professors' experiences support the studies' sentiment that active learning is important for teaching course concepts. The evidence reviewed in this thesis supports positive learning outcomes for comprehension of accounting concepts through active learning and constructivist …

Crossing Boundaries: Brachinites And Their Diverse Asteroidal Origins, B. G. Rider-Stokes, F. A. Davies, T. H. Burbine, E. Maclennan, R. C. Greenwood, S. L. Jackson, M. Anand, Daniel Sheikh, M. M. Grady

Geology Faculty Publications and Presentations

Brachinite meteorites are typically linked to the olivine-rich A-type asteroids. In this study, however, they appear to exhibit unexpected spectral diversity. Spectroscopic analysis of seven meteorites from the brachinite clan reveals two distinct populations in band parameters, overlapping with both the A-type and S-complex asteroids. This dual association shows that a single meteorite group can originate from multiple asteroid taxonomies. Notably, one S-complex-like specimen, Northwest Africa (NWA) 14,635, displays band parameters similar to those of asteroid (65803) Didymos, the target of the European Space Agency's (ESA) ongoing Hera mission. These results underscore the value of spectroscopic characterization of poorly understood …

Optimal Robust Maximum Entropy Behavioral Cloning, Francesco Alessandro Stefano Mikulis-Borsoi

Master's Theses and Capstones

Behavioral Cloning (BC) is an imitation learning approach in which a policy is learned from demonstrations represented as sequences of state-action pairs. Standard BC treats all demonstrations as equally trustworthy; consequently, suboptimal or adversarially corrupted demonstrations can disproportionately influence the learned policy. Robust Maximum Entropy Behavioral Cloning (R-MaxEnt BC) addresses this limitation by learning per-demonstration trust weights M and fitting a maximum-entropy policy that is conditioned on these weights.

In this thesis, I propose OR-MaxEnt BC (Optimal Robust Maximum Entropy Behavioral Cloning), a Convex Mixed-Integer Nonlinear Program (MINLP) with optimality guarantees for selecting which demonstrations to trust given the hyperparameter …

Scaling Of Thermal Conductivity In The Eliot Formation, Ryan Todd Siegel

Master's Theses and Capstones

Heat flow governs the performance of geothermal energy systems, and thermal conductivity is the primary material property controlling subsurface heat transfer. This study investigates heat flow through media with spatially variable thermal conductivity within the heterogeneous Eliot Formation, a metamorphic unit extending across the coastal region of northeast New England. The objective of this work is to develop an approach for scaling thermal conductivity from core-scale measurements to field-scale values representative of geothermal borefield systems.Divided bar thermal conductivity testing, petrographic analyses, geological observations, and existing literature were integrated to construct a MODFLOW model that captures the heterogeneous thermal behavior of …

Comparative Development Of Mof‑Based And Mof‑Free Agnp Functionalized Zno Nanorod–Cotton Fabric Composites For Photocatalytic Applications, Md Al Mamun

Master's Theses

Photocatalysis offers a cost‑effective and environmentally friendly strategy for degrading organic pollutants and addressing energy and environmental challenges. This study initially explored MOF‑based cotton‑fabric‑supported ZnO nanorod composites but found that the MOF component primarily acted as an adsorbent rather than an effective photocatalyst. Consequently, MOF‑free composites were developed by directly growing ZnO nanorods on cotton fabric and functionalizing them with silver nanoparticles. Photocatalytic testing revealed that AgNP‑modified ZnO nanorods, particularly at 10 mM AgNP, exhibited superior dye degradation efficiency, thereby demonstrating a scalable and effective photocatalytic platform.

Morphological Variation Of Lingual Glands In Wild American Alligator (Alligator Mississippiensis) Populations, Benjamin Angalet

Master's Theses

American alligators (Alligator mississippiensis) inhabit diverse aquatic ecosystems including freshwater wetlands, swamps, and estuarine rivers. As apex predators, their physiological resilience has implications for ecosystem stability and long-term conservation. With projected sea-level rise and increasing saltwater intrusion into coastal freshwater habitats, understanding the osmoregulatory capacity of alligators is increasingly important. Unlike marine-tolerant crocodilians such as the saltwater crocodile (Crocodylus porosus), which possess specialized salt-secreting lingual glands in addition to renal and cloacal mechanisms, the morphology and physiological significance of lingual glands in wild American alligators remain poorly understood. This study examined lingual gland morphology and plasma …

Sensing Rna’S Conformation With A Solid-State Nanopore Device At Various Ph And Temperature, Haopeng Li

Graduate Theses and Dissertations

This study uses solid-state nanopore technology to investigate the stability and dynamics of RNA molecules under thermal stress and pH fluctuations. Two distinct mRNA samples were analyzed: (1) heat shock protein (HSP)-encoding mRNA extracted from Sulfolobus solfataricus P2, a thermophilic archaeon inhabiting extreme environments such as geothermal sulfuric hot springs (pH < 4, temperature range: 65–90°C), and (2) total RNA extracted from White Leghorn chickens, which thrive under standard physiological conditions. ΦX174 virion single-stranded DNA (ssDNA) were included as a comparative reference. Nanopores, fabricated in silicon nitride membranes, were used to electrically characterize the structural properties of individual RNA molecules in solution, close to their native environments. The nanopore membrane separates two chambers containing salt buffer solution, where ionic current is the primary measurement parameter. When a voltage bias is applied across the membrane, ion flow and an ionic current can be measured. Charged RNA molecules driven translocation through the nanopore induces pore resistance changes, resulting in detectable current blockade events. Variations in these events provide insights into RNA secondary structure and conformational dynamics. By systematically altering pH and temperature, this study elucidates the effects of environmental stressors on RNA stability and structural integrity. The findings reveal distinct responses between thermophilic HSP-encoding mRNA and mesophilic RNA, underscoring the adaptive mechanisms of thermophilic RNA under extreme conditions. These results contribute to a better understanding of RNA behavior under stress and establish a foundation for future applications in RNA-based diagnostics and biotechnology development.

Synthesis Of Novel 1,2,3-Triarylnaphthalenes Via Intermolecular Dehydro-Diels-Alder Reaction, Ethan C. Dailey

Honors Theses

The photo-dehydro-Diels–Alder (PDDA) reaction is a useful method for the construction of substituted naphthalene derivatives from acyclic precursors. While intramolecular variants of this transformation are well established, intermolecular PDDA reactions remain rare due to challenges associated with controlling reactivity under photochemical conditions. Previous studies suggest that electron-withdrawing substituents can promote intermolecular cycloaddition by increasing alkyne polarization and stabilizing reactive intermediates. In this work, the effect of enhanced electron-withdrawing character on intermolecular PDDA reactivity was investigated through the incorporation of a 2,3,5,6-tetrafluoropyridinyl substituent. Corresponding alkyne substrates were synthesized and subjected to photochemical conditions, resulting in the formation of 1,2,3-triarylnaphthalene products. The …
