Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large-scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris Agreement's 1.5°C or 2° warming targets during this century. While avoiding further CO2 emissions remains the most effective way to prevent environmental destabilization, interest is growing in climate interventions—deliberate, large-scale manipulations of the environment aimed at reducing global warming. These include carbon dioxide removal (CDR) to reduce atmospheric CO2 concentrations over time, and solar radiation modification (SRM), which …

Minimal Supersolution Of Bsdes Driven By Continuous Martingales In A General Filtration, Badr Elmansouri, Mohamed El Otmani

Journal of Stochastic Analysis

In this paper, we study minimal supersolutions of backward stochastic differential equations (BSDEs) driven by a continuous local martingale in a general filtration. We establish existence, uniqueness, and stability results under various mild conditions on the terminal value and the generator. Additionally, we explore the connection between the concept of non-linear expectation and minimal supersolutions, emphasizing the specific properties that are relevant to our framework. We also prove a general monotonic limit theorem and apply this result to determine the smallest constrained supersolution of a BSDE with a possibly non-convex constraint.

An Examination Of Trends And Factors Influencing Teen Retention In 4-H Youth Development Program: A Case Study, Bethany R. Corona

LSU Master's Theses

Teen participation in 4-H has declined nationally in recent years, raising concerns about long-term program sustainability and youth engagement. Understanding the factors that influence teens’ decisions to remain involved in 4-H is critical for informing program design and delivery. Guided by the theory of planned behavior, this qualitative study explored teen perceptions of 4-H programming, youth voice, social influences, communication, and barriers to participation. Data were collected through two group interviews with teen 4-H members representing multiple parishes. Interviews were audio recorded, transcribed verbatim, and analyzed using the constant comparative method through a three-phase coding process consisting of open, axial, …

Qatt&Ck: An Extended Framework For Classifying Adversarial Techniques And Tactics Threatening Quantum Computing Infrastructure Based On Mitre’S Att&Ck, Justin Benjamin Woodring

LSU Master's Theses

The integration of quantum computing into governmental and business processes has raised concerns about potential threats to these systems. To address this, we introduce a novel extension of the MITRE ATT&CK framework, QATT&CK, which provides an extended taxonomy for classifying adversarial Tactics and Techniques in quantum cybersecurity. Our adapted framework bridges the definitions of traditional cybersecurity with a focus on quantum computing infrastructure, enabling a more comprehensive understanding of adversarial behavior in this domain. To evaluate our proposed framework, we leverage current and ongoing research in quantum cyber threats, mapping real-world attacks to our taxonomy to demonstrate its effectiveness in …

A Qualitative Examination Of The Motivations For Homeschooling Among Black Americans, Portia J. Witt

LSU Doctoral Dissertations

This qualitative phenomenological study explored the motivations and lived experiences of African American homeschooling families. Twelve Black parents from multiple states participated in semi-structured interviews. Data were analyzed using Moustakas’ (1994) Modified Stevick–Colaizzi–Keen method and coded thematically using NVivo. Nine themes emerged: autonomy, holistic education, community belonging, online networks, public resources, curriculum gaps, personal values, effective learning, and legacy of harm. While racialization in schools—including tracking, microaggressions, and misidentification—contributed to participants’ decisions, motivations also reflected intersectional factors such as faith, disability, mental health needs, giftedness, and a desire for cultural protection and flexible learning. Findings suggest homeschooling serves as a …

Arbitrage-Free Pricing With Diffusion-Dependent Jumps, Hamza A. Virk, Yihren Wu, Majnu John

Journal of Stochastic Analysis

Standard jump-diffusion models assume independence between jumps and diffusion components. We develop a multi-type jump-diffusion model where jump occurrence and magnitude depend on contemporaneous diffusion movements. Unlike previous one-sided models that create arbitrage opportunities, our framework includes upward and downward jumps triggered by both large upward and large downward diffusion increments. We derive the explicit no-arbitrage condition linking the physical drift to model pa- rameters and market risk premia by constructing an Equivalent Martingale Measure using Girsanov’s theorem and a normalized Esscher transform. This condition provides a rigorous foundation for arbitrage-free pricing in models with diffusion-dependent jumps.

Improving Stem Assessments: Strategies For Increasing The Accessibility And Adoption Of Two-Stage Exams, Kristina Callaghan

LSU Doctoral Dissertations

Over three decades of research have shown that students taught using active learning strategies achieve better learning outcomes compared to those taught using traditional methods. Two-stage exams, which pair a traditional exam with a group component, are an increasingly popular method for incorporating active learning within the assessment component of a course. Previous studies have shown this assessment strategy provides a variety of benefits for students, including increased engagement and collaboration, immediate feedback, and potentially increased content retention. However, the unique circumstances of each instructor can pose a non-trivial barrier to the implementation of two-stage exams. In this thesis, we …

Applications For The Quasi-Atomic Orbital And Constrained Density Functional Theory Methods On Catalytic Reactions, Alvaro David Loaiza Orduz

LSU Doctoral Dissertations

Selective activation of C–O, C–H, and C–C bonds underpins biomass upgrading, alkane functionalization, and CO₂ conversion. Despite their importance, the electronic factors governing catalytic performance remain incompletely understood, and many industrial processes still rely on empirical trends or material-specific observations. This dissertation addresses this gap by applying density functional theory (DFT), thermodynamic decomposition, and electronic-structure analysis to identify unifying principles of reactivity across transition-metal phosphides, vanadate oxides, copper-based electrocatalysts, and mixed IrO₂–RuO₂ layers. This work examines how charge transfer, orbital localization, and ligand-induced perturbations control reaction pathways in diverse catalytic systems. C–O bond scission in 2-methyltetrahydrofuran (MTHF) and methanol was …

Bragging Rights: How Women Candidates Use Endorsements In Strategic Messages, Eva Carter, Tyhlar Holliway

Distinguished Undergraduate Researcher Program

This research analyzes the methods and terminology employed by men and women candidates when they talk about their political endorsements in strategic campaign communication. While existing literature addresses topics such as educating uninformed voters, the influence of endorsements in political campaigns, messaging ethics, celebrity endorsements, and the correlation between money and endorsements, analyses of gender differences in the use and types of endorsements remain underdeveloped. We argue that women candidates, due to the unique vulnerabilities they face in campaigns (Bauer 2015; Lazarus and Steigerwaltz 2018), will be more likely than men to highlight their endorsements in campaign ads. We record …
