Observational studies using real-world data (RWD) can address gaps in knowledge on deprescribing medications but are subject to methodological issues. Limited data exist on the methods employed to use RWD to measure the effects of deprescribing. To describe methodological approaches used in observational studies of deprescribing medications in older adults, we conducted a systematic review in Medline for observational studies published in English (January 1, 2000, to September 14, 2023) that examined the health effects of medication deprescribing in older adults. We described study characteristics and methods, focusing on the operationalization of deprescribing as an exposure and potential time-related biases. …

Misinformation, Disinformation, And The Erosion Of Institutional Trust: The Role Of Social Media In Democracy, Andres Murillo

International Studies (MA) Theses

In recent years, social media-driven misinformation and disinformation have helped erode public trust in democratic institutions. This thesis examines how constant exposure to false online content correlates with declining confidence in democracy and evaluates the roles of platforms, influencers, and mechanisms. Using a convergent mixed-methods design, this thesis pairs a quantitative survey with a qualitative analysis of three disinformation case studies: the 2020 U.S. election and the “Stop the Steal” movement, the Rohingya crisis in Myanmar crisis, and Russian denial of wartime atrocities in their invasion against Ukraine. Drawing on classical and modern propaganda theories (Lasswell, Herman & Chomsky, RAND’s …

A Trauma-Informed Analysis Of Legal Intervention In Cases Of Child Emotional Maltreatment, Judith G. Mcmullen

University of Florida Journal of Law & Public Policy

Child emotional maltreatment (CEM) has been recognized as a widespread, serious social problem that is linked to a variety of adverse physical and mental effects that follow affected children into adulthood. The justice system has responded to calls to action by mental health professionals, and for more than two decades, federal and state laws have included child emotional maltreatment on the list of caretaker behaviors that can trigger child protection action. Despite the potential for meaningful action, recent data shows that occurrence rates of CEM are quite high, while rates of official reporting and intervention remain low. This Article examines …

Legislatively Inhibiting Children's Development Of The Mens Rea To Commit Genocide During Adulthood, Susan H. Bitensky

University of Florida Journal of Law & Public Policy

This Article concerns how legislatures in America are stanching development of the criminal intent to commit genocide. Lawmakers have taken aim at genocide, not through the barrel of a gun, but, rather, by imbuing schoolchildren with values and psychological attributes that gradually counteract development of a génocidaire’s mens rea. Of course, sans mens rea, sans perpetration of this, the “crime of crimes.”

The counteractant process is the result of joining a substantively targeted pedagogy with the force of law so as to create state genocide-education mandate statutes. There has been a certain prescience in this. Accumulating expert opinion, studies, and …

Objective Phone Use During Time With One’S Partner: Associations With Relationship And Individual Well-Being, Brandon T. Mcdaniel Phd, Sabrina Uva, Victor P. Cornet, Michelle Drouin

Health Services and Informatics Research

When a person chooses to interact with their phone instead of their partner (e.g., technoference, phubbing), it may diminish interactional quality, relationship satisfaction, and well-being. However, much of the research on technology use in relationships has utilized self-reports. We extend prior work by objectively measuring smartphone use in a sample of 247 adult participants (75% women; mean age = 30.87 years) to better understand the extent of use around one’s partner and the connection between this use and relational and personal well-being. Participants completed an online baseline survey and 8 days of phone tracking and nightly time diaries. On average, …

Educational Specialist, 2020-current

Mindfulness-based interventions (MBIs) have gained attention as promising tools for improving student well-being, yet their effectiveness and cultural relevance for Hispanic/Latinx immigrant youth remain underexamined. This Systematized Review evaluates the current literature on school-based MBIs targeting this population, with a focus on their cultural considerations, efficacy, and participant acceptability. Using PRISMA guidelines, studies were identified across research databases and Google Scholar. Inclusion criteria required that interventions involve mindfulness practices, take place in school settings, and include Hispanic/Latinx immigrant youth. Findings from the limited number of eligible studies suggest that mindfulness-based interventions may reduce symptoms of anxiety, depression, and trauma while …

Lipid Nanoparticle-Mediated Drug Delivery To Cns Targets, Purva Khare

Electronic Theses and Dissertations

Lipid nanoparticles (LNPs) have revolutionized drug delivery, particularly in the delivery of gene silencing siRNA to the liver (Onpattro) and COVID-19 mRNA vaccines (Pfizer-BioNTech, Moderna). It is no exaggeration to state that the LNP delivery technology has protected billions of vaccinated people against a severe COVID-19 infection and subsequent mortality. Despite extensive research on LNPs for hepatic and muscle delivery, their potential for brain drug delivery remains underexplored. Many neurological disorders lack effective treatments, making LNP-based approaches promising for crossing or targeting drug delivery to the blood-brain barrier (BBB). Brain endothelial cells (BECs), a key component of the BBB, play …

Popular Culture As Conduit: Navigating Integrated Marketing Communication In An Age Of Hyperconsumerism, Abbey N. Mccann

Electronic Theses and Dissertations

This dissertation examines the discipline and practice of integrated marketing communication, acknowledging the limitations inherent in analyzing a field deeply embedded in the structures of hyperconsumption. This inquiry adopts a constructive hermeneutic approach, interpreting the dialectical tensions that define integrated marketing communication. These tensions include that between commercial imperatives and cultural critiques, which are further complicated by the influence of popular culture and shifting political climates. As popular culture increasingly intersects with sociopolitical discourse, brands are compelled to navigate these dynamics publicly. This evolving landscape reshapes consumer perceptions and brand strategies, reinforcing integrated marketing communication’s role as both a cultural …

Comparison Of Finite-Amplitude Acoustic Models: Single Equation Of Motion For Potential Vs System-Level Approaches, Mohammad Javad Mohaghegh Kojidi

LSU New Orleans Theses and Dissertations

This study evaluates two finite-amplitude acoustic models, by solving the associated equations of motion (in potential form), and then compares the results with recent studies using hyperbolic system-level approaches. An implicit numerical method is employed to solve the second-order equations in one dimension. The performances of the Diaz et al. (2018) and Blackstock (1963) models in approximating the acoustic special case of the Euler system, via velocity profile plots and related metrics, are evaluated and compared. Working in the setting of the classical signaling problem with sinusoidal input, present results (using the single equation of motion approach) provide independent confirmation …

Evaluating Immersion And Agency In Ai-Assisted Live Murder Mystery Games, Seraphina C. Courtney

LSU New Orleans Theses and Dissertations

This thesis explores the impact of AI-assisted narrative generation on player immersion and agency in a live-action roleplaying (LARP) experience. A live-action murder mystery game was designed and run in two formats: a static version with GPT-4 generated characters, dialogue, and stage directions, and a dynamic version where players created their own characters and improvised freely, guided by AI-generated narrative beats, a story element that moves the plot forward [21], that provided a narrative scaffolding for the players. The dynamic version employed a distributed computer vision system that tracks the movement of key items in the play-space so their relevance …

Real-Time Fiducial Marker Based Localization For Autonomous Unmanned Aerial Vehicle Navigation, Sourav Raxit

LSU New Orleans Theses and Dissertations

By harnessing fiducial markers as visual landmarks in the environment, Unmanned Aerial Vehicles (UAVs) can rapidly build precise maps and navigate spaces safely and efficiently, unlocking their potential for fluent collaboration and coexistence with humans. Existing fiducial marker methods rely on handcrafted feature extraction, which sacrifices accuracy. On the other hand, some deep learning pipelines for marker detection fail to meet real-time runtime constraints crucial for navigation applications. In this work, I propose YoloTag- a real-time fiducial marker-based localization system. YoloTag uses a lightweight YOLO v8 object detector to accurately detect fiducial markers in images while meeting the runtime constraints …

Induced Helical Anisotropy In Permalloy Thin Films And Patterns, Md Mahmudul Hasan

LSU New Orleans Theses and Dissertations

The goal of this research was to create thin films with induced helical anisotropy and investigate magnetic properties of such films and their patterns. An alloy of 20% iron and 80% nickel (permalloy) was used because of very small magnetocrystalline anisotropy and magnetostriction. First, an unconventional method was used to deposit films with uniaxial anisotropy by sputtering the films onto silicon substrates in the presence of a uniform field of 50 Oe along the substrate plane. This resulted in magnetic atom pairs ordering along direction of the field during film growth. Shapes of hysteresis loops measured at different angles were …

Counteracting Cascades Challenge The Heterogeneity-Stability Relationship, Jordi Sola, Tom P. Fairchild, Matthew J. Perkins, James C. Bull, John N. Griffin

School of Biological and Marine Sciences

Spatial environmental heterogeneity is widely assumed to enhance ecological stability by promoting refugia, biodiversity and asynchrony. Yet, we lack field experiments testing this fundamental relationship and its underlying mechanisms in naturally assembled multitrophic systems. To address this gap, we monitored experimental substrates replicating topographic heterogeneity on a rocky shore over 3 years. Contrary to theory, heterogeneity showed no net effect on community stability due to four counteracting pathways. Heterogeneity increased stability by (i) providing refugia that enhanced population stability and (ii) boosting species richness, which promoted asynchrony. At the same time, it decreased stability by (iii) reducing a dominant non-native …

Decision-Making Methods Under Uncertainty In Discrete Multi-Objective Optimization, Chathuri Malee Aththanayake

Masters Theses and Doctoral Dissertations

This dissertation investigates decision-making methods in Uncertain Discrete Multi-objective Optimization Problems (UDMOPs), where uncertainty arises in both objective function and constraint coefficients. The study pursues three main goals: (1) constructing sensitivity regions in the objective space to handle objective-wise uncertainty, (2) constructing sensitivity regions in the decision space to handle feasibility uncertainties, and (3) developing methods to sort, group, and prune uncertain solutions based on their similarity. Each goal proposes a method to explore uncertain solutions and quantify their level of uncertainty. Based on this, solutions are classified as low and high-risk solutions, according to the Decision-Maker (DM)'s preferences and …

Density Functional Theory Modeling Of Heterogeneous Reactions Of Hydrocarbon Intermediates On Silicon Carbide: Surrogate Kinetic Model Development For Chemical Vapor Infiltration, Atal Bhowmik

Masters Theses and Doctoral Dissertations

This study investigates the decomposition mechanism of Methyl trichlorosilane during Silicon Carbide deposition from Chemical Vapor Infiltration to produce SiC-based ceramic matrix composites. High-performance applications require SiC-based materials; however, producing them presents difficulties due to limited deposition rates, high energy consumption, and uneven coatings. To overcome these challenges, the mechanism of SiC formation needed to be understood completely. Modeling surface reactions of decomposition on the substrate using Density Functional Theory is the key point of current research. By focusing on the adsorption, reaction, and desorption mechanisms that control SiC development, our method incorporates quantum mechanical models. Using Transition State Theory, …
