Hydrothermal systems in volcanic calderas are critical in signalling volcanic unrest, forming ore deposits, and sustaining chemosynthetic microorganisms. Analysis of a ~3500-year sequence of sediments collected from the Santorini caldera, Greece, during International Ocean Discovery Program (IODP) Expedition 398 reveals the behaviour of a prolonged paleo-hydrothermal system. Sediment geochemical and metagenomic data record vigorous hydrothermal activity and metal fluxes for ~1100 years, within a 2270-year window between two major eruptions. Sediment hydrothermally-derived trace metals are significantly enriched over background (~200-fold for As and Hg, and 10–50-fold for Mn, Sb, Mo, and V), with long-term metal fluxes (9 t yr^{−1 …}

Accidental Transdermal Buprenorphine Patch Overdose In An Older Adult: A Case Report, Hashem Shogdar, Ahmed Aljohani, Yousef Almubarak

Saudi Toxicology Journal

Background: Buprenorphine is an opioid that is generally used for chronic pain and opioid dependence. Its pharmacological ceiling effect on respiratory depression gives it a comparatively favorable safety profile relative to other opioids. Despite its safety profile, inappropriate use can still result in clinically significant opioid poisoning. This case report highlights a case of accidental buprenorphine overdose in an aged patient. It illustrates the clinical presentation and preventive considerations associated with this uncommon but critical event. Case presentation: A 65-year-old woman with recent left total knee replacement was brought to the Emergency Department (ED) after being found drowsy and unresponsive …

Examining Six Domains Of Resilience With Latinx College Students From Migrant Farmworker Backgrounds: A Quasi-Experimental Single Case Design Study, Rebecca Dickinson, Raissa Miller, Cian L. Brown, G Michael Russo, Emma Knowles

Trauma Counseling and Resilience

Resilience-building interventions show promise in higher education, yet few studies focus on Latinx college students from migrant farmworker backgrounds (LMFWs), a group facing significant challenges such as acculturative stress, mixed familial immigration status, and educational discontinuity. This quasi-experimental single-case design study examined resilience domains among LMFW students participating in a group-based intervention informed by the predictive 6-factor resilience model. Resilience was measured across six domains: collaboration, vision, tenacity, reasoning, health, and composure, using standardized assessments adapted from Rossouw and Rossouw (2018). Pre- and post-intervention scores were visually analyzed to assess change at the individual level. Results indicated a evidence of …

The Roles Of Adverse And Benevolent Childhood Experiences In Posttraumatic Growth And Social Connectedness Following Interpersonal Trauma, Margaret Poandl, Emily Kitching, Daniel Gutierrez, Yuqi Zhang

Trauma Counseling and Resilience

Interpersonal trauma, such as childhood abuse, neglect, and intimate partner violence, is a prevalent and harmful form of trauma associated with deleterious psychosocial outcomes. Despite its negative impacts, individuals exposed to interpersonal trauma may also experience posttraumatic growth (PTG). While adverse childhood experiences (ACEs) are known risk factors and benevolent childhood experiences (BCEs) are potential protective factors for adult outcomes, little is known about how combinations of ACEs and BCEs influence PTG. This study examined how combinations of ACEs and BCEs relate to PTG and social connectedness among individuals who have experienced interpersonal trauma. Using cross-sectional survey data from 615 …

Trauma Counseling and Resilience

In the wake of the COVID-19 pandemic, our partners in a Central American immigrant enclave reported an increasing need to support parents and children whose mental health was negatively impacted by the confluence of underlying systemic stressors and traumatic experiences. Using our existing family-centered participatory action research (FCPAR; Letiecq, Vesely, et al., 2022) approach and guided by the transcreation model (Nápoles & Stewart, 2018), we co-constructed a mental health intervention in partnership with community members, via our community advisory board (CAB). Essential to this process was building the intervention with the community, ensuring that it was culturally and contextually grounded …

Collective Trauma And Systemic Negligence: Exploring South Korean Disasters Through Media And Cultural Narratives, Jung H. Hyun, Eunae Han

Trauma Counseling and Resilience

Disaster trauma often occurs at multiple levels, with the systemic level highlighting its collective impact on survivors. Betrayal trauma, inflicted by trusted individuals or institutions including the government, further compounds this experience. Drawing on historical and contemporary challenges in modern Korean history and recognizing their collective impact on the Korean population, this paper examines Korean betrayal trauma stemming from disasters, introduces a new concept of political betrayal trauma, and explores how media can serve as a tool for healing. Through a fictional case study, this paper illustrates how collective cultural narratives support both survivors and the broader society in validating …

Secondary sources were also used, including published …

Phantoms Of The Self: An Art Installation On The Commodification Of Anik-Anik Culture, Vito Lomod, Minuet Deniña, Jaihzel Failana, Joshua R. Marcial

DLSU Arts Congress Conference Proceedings

The practice of anik-anik culture remains relevant and prominent among Filipinos, especially among Gen Z. Decorating, collecting, and preserving miscellaneous items as an extension of one’s identity and memory exemplifies the Filipino maximalist aesthetic. In context, Filipinos are naturally inclined to be maximalists, driven by the desire to connect and the tendency to fill empty spaces, hence the aesthetic of Filipino maximalism. Usually, this is evidenced in, but not limited to, consumption and fashion practices. Correspondingly, its current practices have also sparked discussions about the effects of consumerism and the dilution of the origins of anik-anik, which is deeply rooted …

“Shh!” Bleaching As An Auto-Destructive Art Method Of Representing The Silencing Of Women, Kristelle Tenero De Leon

DLSU Arts Congress Conference Proceedings

This paper discusses the artistic representation of the muffling of women’s voices and the culture of silence through a theoretically auto-destructive method of artmaking—bleaching using mark-making on textile. Through studio art research, the reductive and erasing properties of bleaching agents are used by bleaching printed images of women in fabric to metaphorically represent and articulate the existence of silencing imposed upon women. Guided by the lens of feminism and Gustav Merger’s manifesto of auto-destructive art, this work presents the artistic images of 13 women across Philippine history—from the babaylans to Maria Ressa—on textile, imbued with bleaching effects. Moreover, the work …

Kapwa Beckett: Co-Performance, Pakikipagkapwa, And Relational Meaning-Making In Philippine Stagings Of Samuel Beckett, Christian Gabriel Tolentino

DLSU Arts Congress Conference Proceedings

This reflective-practice study examines how kapwa and pakikipagkapwa emerged through translation, rehearsal, staging, and reception in three Philippine productions of Samuel Beckett: Endgame (2016), Happy Days (2019), and the devised classroom piece Beckett, Godot & Us Waiting (2023). Using comparative production analysis and a dialogical co-performance orientation drawn from Dwight Conquergood, I analyze rehearsal exercises, adaptation notes, production materials, staging decisions, and remembered performer-audience encounters. The analysis identifies distinct relational practices across the productions: collaborative localization and sensory dramaturgy in Endgame; negotiated media adaptation and mediated intimacy in Happy Days; and devising, Meisner repetition, physical trust, and shared post-pandemic waiting …

Atomos Komiks - Making Learning Fun With Science Entertainment, Jerome Aizpuro Suplemento Ii, Julius Noah Hernandez Sempio

DLSU Arts Congress Conference Proceedings

With portable digital devices imposing themselves on the already precarious attention span of the Filipino youth, and with raising concerns about degrading literacy of schoolchildren, it is imperative to find creative and entertaining means to inspire the young studentry to engage in dedicated educational materials. This paper explains the methods being used by a small group of artists, scientists and writers to create content for “science entertainment” in comics format. By combining principles of conceptual compression, knowledge indexing and low-elaboration persuasion techniques to develop knowledge “anchors”, the team aims to generate participatory engagement among readers and stimulate their cognitive innovation. …

Indigenous Pedagogies As An Arts-Based Framework For Education 4.0, Andylyn Simeon

DLSU Arts Congress Conference Proceedings

While Education 4.0 promises to cultivate 21st-century skills like creativity and critical thinking, the reality often falls short. Current frameworks are heavily technocentric, prioritizing digital tools and measurable data over the communal, emotional, and spiritual depth that true learning requires. This paper argues that we can restore balance to this digital shift by looking toward Indigenous Pedagogies (IPs). Far from being “obsolete” relics of the past, these are sophisticated, arts-based systems rooted in storytelling, ritual, and land-based creation that can offer a creative blueprint for the human-centered goals that Education 4.0 claims to value. Through a qualitative synthesis, I deconstruct …

Large-Scale Asymptotics In Fixed-Sample And Sequential Multiple Testing, Rahul Roy

Doctoral Theses

The advent of large-scale data acquisition technologies has led to the routine emergence of massive, dynamically evolving datasets. This has created a pressing need for statistical methodologies capable of operating effectively in both static and sequential data environments. Multiple hypotheses testing, a central tool in such settings, must therefore be adapted to both fixed-sample and sequential frameworks to ensure effective decision-making while controlling error rates. This thesis comprises two main parts. The first part addresses fixed-sample multiple testing under dependence in a Bayesian framework. Building upon the two-group mixture normal model of Bogdan et al. (2011), we extend their methodology …

Vetiver Phytoremediation Of Nitrate-Rich Munition Wastewater: Biomass Valorization Within A Circular Economy Framework, Arash Aliasghar, Rupali Datta, Zhiming Zhang, Christos Christodoulatos, Dibyendu Sarkar

Michigan Tech Publications

Industrial munition facilities generate nitrate-rich wastewater that requires effective and sustainable treatment before discharge. While vetiver grass (Chrysopogon zizanioides)-based phytoremediation has shown promise in nitrogen removal, most studies have been limited to small-scale experiments under low nitrogen concentrations, providing limited guidance for system-level design under elevated loading. This study evaluates a greenhouse-scale phytoremediation system using vetiver grass to treat wastewater containing 1000 mg N/L nitrate and 50 mg/L COD. Plant coverage densities of 2%, 4%, and 6% (w/v) were assessed to quantify optimum density as a design parameter for optimizing nitrate removal. A 6% coverage achieved the highest efficiency, reducing …

Properties Of Enjoyable Mathematical Contexts From The Student Perspective, Emilie Nadine Hendrickson

Theses and Dissertations

Researchers continue to grapple with how to meaningfully engage students in mathematical content. Many students report disengagement due to perceptions that mathematics is difficult, irrelevant, boring, or anxiety-inducing. This study sought to understand how students interpret and respond to different mathematical problem contexts, with particular attention to the reasons students describe certain problems as enjoyable or unenjoyable. Using semi-structured interviews, this research examined student responses to a variety of mathematical problem types primarily across affective engagement. Students reflected on specific problem contexts and explained which features supported or hindered their enjoyment and engagement. Students described that contexts were enjoyable have …

Comparing Principal Component Analysis And Sequential Fusion Deeponet With Varying Dataset Size For Design Space Exploration Of Hypersonic Flow, J. Dallan Trentman

Theses and Dissertations

Design space exploration and optimization of hypersonic vehicles is costly due to the difficulty of producing high fidelity CFD simulations in the hypersonic domain. Reduced order modeling can allow for design optimization at a fraction of the computational cost. This paper investigates the amount of training data required to produce an accurate Reduced Order Model. A PCA based ROM is developed and compared to a Sequential Fusion DeepONet by comparing model prediction accuracy, training time, and prediction time, across dataset sizes from 25 samples to 1024 samples. These models are applied to 2D hypersonic CFD simulations of the Orion reentry …

Resonant Shock Plate Simulation And Prediction Using Modal Substructuring, Harrison C. Denning

Theses and Dissertations

Aerospace structures such as rockets can experience various shock events during flight, such as stage separation or impacts. These shock events can expose components inside the rocket to large accelerations and stresses which in turn can damage the parts. Shocks are often simulated in the lab using a resonant shock plate test. Resonant shock plate testing is often used to qualify aerospace parts, as it can mimic the shocks experienced during launch and stage separations. However, during the course of development, both the definition of the shock environment and the design of the subcomponent tend to change, so that multiple …

Rfsoc Based Ground Penetrating Radar For Detection And Avoidance Of Underground Utilities, Brady Bowerbank

Theses and Dissertations

Preexisting underground utilities present a considerable danger to underground boring projects. Gas and electrical lines can be damaged, leading to major economic impact and even loss of life. While maps of underground utilities exist, they are not always accurate and gas and electrical lines can shift over time, necessitating tools to accurately detect utilities so that crews can steer the machines away from any possible danger. In this thesis, the design of a new frequency-modulated continuous-wave (FMCW) ground penetrating radar (GPR) is outlined. The design of a lightweight, flexible radar is demonstrated using the CASPER FPGA framework with an operating …

Electronic Theses and Dissertations 2020 - Present

This thesis characterized the water quality and bacterial communities in nine hard clam hatcheries over two production years through weekly or biweekly water quality and chemistry monitoring, monthly bacterial plating in the second year of production, and select 16S microbiome sampling at select hatcheries to address production bottlenecks and support the reliable production of high-quality seed for Florida’s growing hard clam aquaculture industry. Logistic regression models showed that water source was distinguished by pH, salinity, alkalinity, and nitrite, whereas geographic location was distinguished by temperature, salinity, nitrate, and calcium; temperature, dissolved oxygen, salinity, and alkalinity distinguished seasons. Vibrio bacteria differed …

Contributions Of Arginine And Nitrosative Stress To Huntington’S Disease Progression, Ian D. Gaudet

Electronic Theses and Dissertations 2020 - Present

Neuroinflammation is a well-established component of Huntington's disease (HD) pathogenesis, yet the intricate molecular mechanisms that govern this process remain a topic of ongoing research and debate. This dissertation elucidates a novel pathway linking arginine metabolism and nitrosative stress to core HD pathology. We found that the arginine transporter SLC7A2 is selectively upregulated in various HD cellular models and patient samples. Our findings reveal that this upregulation drives an overactive inflammatory response, leading to abnormally high inducible nitric oxide synthase (iNOS) induction and subsequent nitric oxide (NO) production, which causes excessive protein nitrosylation and an increase in mitochondrial fragmentation.

The Purpose Of Integration Beyond Expression: Emerging Human Patterns And Possible Selves In A Computational Model Of Self-Reflection, Lore Olson

Electronic Theses and Dissertations 2020 - Present

Self-reflection encompasses the dual modes of Integration and Expression, the processes of actively attempting to know oneself and doing something with that knowledge. Each mode serves a distinct purpose; however, the long-standing idea that Integration is needed before Expression can occur has been challenged by the demonstrated ability to create and maintain a small, stable identity through constant Expression. Across three studies, a theory was tested of the Integration mode as a method of quickly and sustainably distributing clusters of organization across the self-structure, allowing for diversity in the selves one can coherently express. Study one replicated the previously observed …

Data Centers As Engines Of Corporate Tax Base Restructuring, Reuven S. Avi-Yonah, Domenico Imparato, Karen Sam

Articles

Globalization has eroded the corporate income tax by undermining both source-and residence-based taxation. Before the 1980s, large capital-exporting countries could impose relatively high tax rates on multinationals and extend taxation to low-taxed foreign income earned through controlled foreign corporations, as exemplified by the U.S. adoption of subpart F in the Revenue Act of 1962. That regime supported corporate tax revenues that reached roughly 25 percent of total U.S. receipts in the mid-20th century.

Globalization changed that equilibrium. Multinational corporations gained the ability to arbitrage national tax systems by relocating and reporting profits in low-tax jurisdictions. Active income largely escaped source …

Using Hip Hop Pedagogy To Bridge The Culture Of Black Children Identified With Behavioral Disorders In The Curriculum, Monique Matute-Chavarria, Pricella Morris, Monica R. Brown

Journal of the Arts and Special Education

Black and other minoritized children have listened to hip hop in the streets, in clubs, in basements, and anywhere else that they could create a space to enjoy this art form. However, hip hop has not always been welcomed in school spaces because of the lyrical content. Despite the objections to hip hop (specifically rap), minoritized children often look to it as representative of who they are and the communities they come from. Therefore, in this paper, we propose the use of hip hop strategies in the schools, utilizing its pillars (i.e., rap, DJing, breakdancing, graffiti art, and knowledge of …

Developing Flow Theory For Black Girl Genius: A Conceptual Framework Grounded In Discrit, Endarkened Feminist Epistemology, And Hip-Hop Pedagogy, Keishana L. Barnes, William C. Hunter

Journal of the Arts and Special Education

Twice exceptional Black girls, those who are both intellectually gifted and identified with a disability, navigate classrooms shaped by racism, ableism, and sexism. These overlapping systems often render their brilliance illegible, leading to misidentification, exclusion, and under-support in both gifted and special education. This conceptual essay introduces Flow Theory for Black Girl Genius, a liberatory framework that considers Disability Critical Race Theory (DisCrit), Endarkened Feminist Epistemology, and Hip-Hop Pedagogy. DisCrit helps uncover the structural barriers that marginalize students at the intersection of race and disability. Endarkened Feminist Epistemology centers ancestral, embodied, and spiritual ways of knowing rooted in Black …

Evaluation Of Mechanical Properties And Seal Strength Of Medical Packaging Materials Before And After Supercritical Co₂ Sterilization, Camila Madriz Pizarro

Theses

The sterilization of medical devices is critical in the prevention of infections in healthcare settings. Ethylene oxide (EtO), gamma irradiation, and steam sterilization have been the standard sterilization processes in healthcare settings, where the packaging system remains the most important barrier between the sterilized instrument/device. Safety concerns and regulatory pushback on conventional sterilization methods have pushed for further research on new sterilization techniques. Among the emerging sterilization technologies, one candidate that has garnered considerable attention is Supercritical CO2 sterilization. However, there is a lack of literature to support the compatibility between scCO2 and common medical packaging materials. The present study …
