DLSU Senior High School Research Congress Conference Proceedings

Heavy metal contamination in natural water sources poses a significant threat to public health, aquatic ecosystems, and environmental safety in affected communities. This study explores the utilization of Mango Peel Activated Carbon (MPAC), derived from ripe mango (Mangifera indica) peels, as a biosorbent for removing Iron(III) from aqueous solution, which underwent a sequence of physical and chemical activation processes. This examined key parameters such as A: adsorbent dosage (0.025–0.1 g/L), B: contact time (15–35 minutes), and C: temperature (25–35 °C), in order to assess its potential as a sustainable clean water solution. A Box-Behnken Design under Response Surface Methodology (RSM) …

“Neither Living Nor Dead”: From Nazgûl To The Sídhe In Tolkien's The Fellowship Of The Ring (1954), Noelia Ramos

Journal of Tolkien Research

This study explores the influence of Celtic supernatural folklore, particularly the banshee tradition, on Tolkien’s depiction of the Nazgûl in The Fellowship of the Ring. Using W.B. Yeats’ Fairy and Folk Tales of the Irish Peasantry (1888) and the Celtic Twilight movement as a comparative framework, it analyses “A Short Cut to Mushrooms” and “A Knife in the Dark”, focusing on liminality, spectral presence, and supernatural dread. These parallels are further contextualised through reference to early Irish texts The Táin Bó Cúailnge and The Boyhood Deeds of Fionn, central works within the Celtic literary compilation known to Tolkien …

Mechanical, Thermal And Fire Behaviour Of Hemp-Based Composites With Different Binders For Sustainable Building Applications, Anilcan Aygun, Fahri Birinci, Selim Aytac, Ali Kemal Ayan, Hasan Alp Sahin, Ibrahim Isildak

Journal of Sustainable Construction Materials and Technologies

This study investigates the physical, mechanical and thermal properties of hemp-based composites produced with traditional binders such as lime, cement, gypsum, clay, and water-based glue. Hemp fractions of different sizes (splinter, shiv, fiber and powder) were combined with these binders to manufacture cube and plate specimens, which were tested for physical, mechanical, thermal, and temperature resistance properties. The study aims to compare the mechanical, physical, thermal, and fire behaviour of these composites to assess their suitability for sustainable construction applications. The hemp-based composites were tested for unit weight, water absorption, compressive strength and thermal conductivity. Most specimens are lightweight (<1000 kg/m3), and exhibit good thermal insulation performance and high compressive deformability, making them suitable for seismic-prone regions. The glue-based composite had the lowest unit weight, measured as 330 kg/m3. Thermal conductivity ranged from 0.051 to 0.243 W/m· K, with several mixtures performing better than natural pumice. While cement-based composites showed the highest compressive strength, ranging from 5.5 to 24.8 kg/cm2, natural hydraulic lime is the lowest. Water absorption was high, and moisture release occurred slowly across all hemp fractions. Combustion tests indicated that hemp-based materials have moderate temperature resistance, with charring temperatures ranging from 238–265°C for raw hemp and 300–385°C when mixed with binders. Overall, hemp-based composites are lightweight, eco-friendly, and suitable for non-load-bearing construction and insulation applications. However, improvements in moisture resistance and long-term durability are necessary to enhance their practical applicability.

Critical Heavy Metal Contamination In The Tigris River, Baghdad: A Comprehensive Assessment Using The Metal Index (Mi), Talib Kamil Abed, Abass J. Kadhem, Muwafaq Hussein Al-Lami

AUIQ Technical Engineering Science

One of the most important rivers in Iraq is the Tigris River, which serves as the primary source of drinking water and irrigation for agricultural purposes. In recent events, researchers have identified growing concerns about heavy metal contamination in the river. To decide the status of the Tigris River, the metal index (MI) was used in this study. To conduct this study, three locations were chosen along the river, and eight likely harmful heavy metals were examined: iron (Fe), lead (Pb), nickel (Ni), zinc (Zn), chromium (Cr), cadmium (Cd), manganese (Mn), and copper (Cu). The results were worrying. The metal …

Aquifer Characteristics And Groundwater Flow Modeling For Sustainable Water Resources Development And Planning Using Modflow Software In India, Ravi Sharma

AUIQ Complementary Biological System

MODFLOW is one of the most commonly used numerical models for simulating groundwater flow. Its structured data design and compatibility with GIS tools make it suitable for groundwater assessment and planning. Groundwater forms an important part of the hydrological cycle and occurs within the pore spaces of sedimentary rocks or within fractures in hard rock terrains. Although its distribution beneath the surface is not always uniform or predictable, it is still considered one of the cleanest, most accessible, and quickly available freshwater sources. Numerical groundwater models help convert complex subsurface processes into simplified relationships that describe flow behavior. Even though …

Facing The Constitution: How Facial Recognition Technology Threatens Fourth Amendment Protections And Deepens Racial Inequality, Bailey Mandell

Cardozo Journal of Equal Rights and Social Justice (ERSJ) Blog

It is very unlikely you have ever consented to a police lineup. Yet if you have a driver’s license or a social media account, you may already be in one. A new kind of digital lineup has emerged, one that never ends and requires neither your knowledge nor consent. Facial recognition technology (“FRT”)is a biometric identification method that creates a digital template of a person’s face using measurements such as the distance between the eyes, the width of the nose, the length of the jawline, and the shape of the cheekbones. Algorithms then compare that template either to a second …

SACAD: Scholarly Activities

Competency based education helps to develop skills for nursing students to help them prepare for graduation and the workforce. Concept based nursing delivers knowledge to students and can help to build some clinical judgement and critical thinking. Globally there is a shift moving toward competency-based education attempting to allow nursing students appropriately apply their conceptual knowledge in a clinical setting.

Views And Experiences Regarding Workplace Genetic Testing: Findings From A National Survey Of U.S. Employees., Drew Blasco, Sarah Mccain, Subhamoy Pal, Wendy R Uhlmann, Rebecca Ferber, Kunal Sanghavi, Elizabeth Charnysh, Anya E R Prince, Charles Lee, J Scott Roberts, Insight @ Work Consortium

Faculty Research 2026

The emergence of voluntary health-related genetic testing in workplace wellness programs indicates a need to understand employees’ views and experiences regarding workplace genetic testing (wGT). A large, diverse national sample of employed adults (N=2000; median age=43 years; 51.1% female; 33% non-white) completed a web survey of their wGT views and experiences. Although 80% of participants indicated their employer did not offer wGT, 54.1% were interested in testing, especially (somewhat/very) for cancer (89.2%), heart disease (93.1%), and Alzheimer’s disease (85.3%). Characteristics associated with wGT interest included younger age (< 55 years), Hispanic/Latino ethnicity, genetic testing experience or familiarity, and a positive family medical history (all p< 0.05). Reasons for pursuing wGT (e.g., inform health behaviors) were endorsed more frequently than reasons for declining (e.g., insurance/employability concerns). Among participants offered wGT (20%), 60% indicated having undergone testing. Test uptake was associated with personal medical history, greater familiarity with genetic testing, and self-reported physical health (all p< 0.05). A minority of employed adults surveyed reported being offered, or having had, wGT. Nevertheless, many employees are potentially interested in wGT, particularly for common diseases. Although employees have wGT concerns, many view it as beneficial to inform health behaviors and decisions.

Background: Improving equitable access to fresh fruit and vegetables (FV) remains a critical public health priority in the UK, particularly in low-income communities where affordability, accessibility, and social barriers limit healthy food choices. The Fresh Street Community scheme, a place-based FV voucher initiative in England, aims to enhance dietary equity by enabling households to purchase fresh produce from local community centres. Building on prior feasibility research, this study applies a systems-modelling approach to explore how multiple enablers and barriers interact to influence scheme uptake and sustainability.Methods: Using Total Interpretive Structural Modelling (TISM) combined with MICMAC analysis, we engaged research team …

The Difficulty With Setting A Standard Based On Difficulty: The Role Of Validity In Determining Assessment Standards., Steven Burr, Daniel Zahra, Iain M Robinson

Peninsula Medical School

When setting standards for high-stakes assessments, it is necessary to be clear whether the primary criterion should be importance or difficulty. While standard setting practices frequently rely on the difficulty to determine passing or failing thresholds, this can undermine the intended inferences and uses of assessments. Standard setting based on difficulty conflates importance with subjective perceptions of difficulty, misguiding decisions about what candidates need to demonstrate for safe and effective practice. We explore several reasons why difficulty does not align with the aims of assessment and how prioritising importance can better reflect the intended uses and inferences of a test. …

Awe Only At What You See, Thomas Marinelli

Philosophy Student Scholarship

The sublime, as developed by Immanuel Kant in Critique of Judgment and later framed and deconstructed by Jacques Derrida in The Truth in Painting, is much like admiring a view—standing before the ocean, seeing nothing but an endless expanse of water stretching beyond the horizon. Yet this vastness is only visible through the lens of our own perception. Imagine being placed in the middle of that ocean, surrounded by nothing: a sensation of weight, anxiety, perhaps even freedom and clarity, might emerge—a powerful emotion never before felt. That situation itself is not the sublime; rather, it is the feeling, the …

Gnsi Decision Brief: The Three-Body Trap: The New Geometry Of Nuclear Deterrence, Seong-Hyon Lee

GNSI Decision Briefs

In the astrophysics of orbital mechanics, the “Two-Body Problem” – predicting the gravitational interaction between two objects, such as the Earth and the Moon – is mathematically solvable. The system is stable, the orbits are predictable, and the variables are calculable. However, if a third independent object of sufficient mass is introduced, the system becomes non-linear and highly unpredictable. As proven by mathematician Henri Poincaré in 1887, no single formula can solve for long-term stability in a three-body system. For eight decades, since the dawn of the nuclear age, global security operated on “Two-Body” physics. The United States and the …

Analyzing Methods To Support Students Left Behind In Colorado Primary/Secondary Schools, Grace Hudson

Undergraduate Theses, Capstones, and Recitals

In the United States, there has been an increase of deportations, since 2024, of undocumented immigrants. This has disproportionally affected Mexicans and others from Latin American countries (Dreby 2012) due to them being the largest group of undocumented people in the United States. One effect of these deportations is an increase in children that are left in the United States while their parent(s) are in detention or have been deported. Some of these children are in mixed-status families, which means that the child has a different citizenship status than their parents or other members in their family, which allows for …

Addressing The Problems Of Data Variations, Quality, And Scarcity In Training Deep Neural Networks, Jian Sun

Electronic Theses and Dissertations

The performance of deep neural networks (DNNs) is strongly influenced by the characteristics and quality of the underlying datasets. This Ph.D. dissertation addresses three pervasive data challenges-imbalance, quality degradation, and scarcity-that commonly hinder the effectiveness of DNNs in computer vision (CV) and natural language processing (NLP) applications.

Class imbalance remains one of the most frequent causes of degraded model generalization. While Focal Loss effectively mitigates inter-class imbalance by assigning higher weights to minority classes, it struggles with intra-class imbalance, particularly in video datasets where longer clips dominate feature representation. To address this, I implement and utilize …

Critical Roles And Critical Rolls: A Frame-Analytical Perspective Of Self-Making, Safe Spaces, And Worldbuilding In Tabletop Role-Playing Games, Cal Quayle

Electronic Theses and Dissertations

Many gamers prefer to play tabletop roleplaying games, or TTRPGs, in order to a) join a community, and b) tell a story collaboratively with friends and acquaintances. This thesis discusses selfhood-making, safe spaces, and allegory in imaginary worlds from the perspective of Erving Goff man’s frame analysis. It relies on a theoretical framework of imagined communities, the magic circle, and subcreation. This research culminated in the understanding that people play TTRPGs for a variety of reasons - collaborative storytelling and exercising critical thinking skills, but respondents overwhelmingly reported that they enjoyed the ability to socialize with friends and strangers, and …

Bridging Professional Development Gaps In Pacrao Through Gamification, Chad Everett Saunders

Electronic Theses and Dissertations

This study examined the extent to which a gamified professional development platform can foster skill development, knowledge application, and engagement among members of the Pacific Association of Collegiate Registrars and Admissions Officers (PACRAO). Grounded in the principles of humanism (Rogers, 1969) and andragogy (Knowles, 1990), and operationalized through gamification (Kapp, 2012), this study evaluated whether game-based mechanics aligned with adult learners’ professional development needs within a geographically dispersed regional association. To address these constraints, a prototype gamified platform, PACRAO University, was developed to provide a flexible, self-paced, and contextually relevant learning environment. Using a quantitative, within-subjects repeated measures design, …

Subsistence And Settlement In Northwest Florida During The Late Archaic-Early Woodland Transition (3500 Bc Through Ad 300), Kerri A. Klein

USF Tampa Graduate Theses and Dissertations

This research presents quantitative and qualitative data on subsistence and cultural transitions in a warm-temperate area of northwest Florida during the Late Archaic-Early Woodland transition (from about 3500 – AD 300). By completing an inventory of the faunal assemblages from two shell middens, I was able to evaluate resource selection and use both within and between sites. Results suggest that site inhabitants utilized consistent resources, despite any documented or potential climatic and ecological change which occurred. Radiocarbon dating establishes the timelines for both Sam’s Creek Cutoff (8FR754), a single-component Late Archaic campsite, and Depot Creek (8GU56), which has a Late …

Adaptations Of Collaborative/Therapeutic Assessment With Survivors Of Torture: Clinical Insights From Shareback Conversations, Samantha Correa

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Survivors of Torture (SoT) experience disproportionately high rates of PTSD, depression, and anxiety (Steel et al., 2009). Many SoT treatment programs use brief assessments to monitor symptoms (McFarlane & Kaplan, 2012). However, research on integrating feedback into treatment had been limited until Colpas et al.'s 2024 study on Sharebacks, a novel approach where clients review their progress with their clinician in structured feedback sessions. Given the therapeutic potential of assessment feedback (Tarocchi et al., 2013; Smith & George, 2012; Poston & Hanson, 2010) and Colpas et al.'s findings on Sharebacks' importance, this study explores how practitioners can most effectively incorporate …

Analogy2kg: An Automatic Pipeline For Deriving Knowledge Graphs From Long-Text Analogies, Kara Combs, Lance E. Champagne, Bruce A. Cox, Christine M. Schubert Kabban, Trevor Bihl, Grace Lemming

Faculty Publications

Analogical reasoning is an increasingly popular, lightweight solution to enable large language model (LLM)-level reasoning without computational complexity. Still, it has yet to be adopted due to its reliance on strictly hand-formatted data. Therefore, we propose Analogy2KG (“Analogy to Knowledge Graph”), as an automatic pipeline that transforms text into a KG format via a fine-tuned version of information extraction (IE) algorithms for long-text analogies. The need to verify that the complex underlying analogical structure of the data is maintained was done via paired samples tests in the creation and validation of this pipeline. Graph density was used to evaluate the …

Social Control And Neglect At A Crossroads: Unpacking The Interactive Effects Of Residential Segregation And Violence On Pretrial Detention, Paige Vaughn, Joshua H. Williams

Faculty Publications

Racial segregation and violent crime are both important predictors of jurisdiction-level criminal justice outcomes, yet little research has examined their influences on front-end detention patterns and how they may interact to shape local punishment practices. The current study uses official sources and Vera Institute of Justice data spanning 1496 decennial county-years (374 counties from 1980 to 2010) to examine the independent and combined effects of county-level racial segregation and violent crime on pretrial detention rates. Drawing on group threat and minority neglect arguments, we find that high segregation levels are associated with neglect, especially in violent areas. Reduced segregation between …

DLSU Senior High School Research Congress Conference Proceedings

The growing contamination caused by the dye and textile industries has generated serious environmental issues due to the release of chemically synthesized dyes such as methylene blue (MB), which are toxic and resistant to biodegradation. This study examines the impact of contact time, adsorbent dosage, and initial pH on the removal efficiency of MB using Citrus aurantium peels as a cost-effective and environmentally friendly adsorbent. The Box-Behnken design methodology was employed to identify optimal conditions for maximum removal. The research consisted of 15 experiments to determine the adsorption capacity under various conditions. Results showed that the removal efficiency was highest …

Into The Spectrum: Investigating The Range Of Color Vision In The Foraging Behavior Of Diacamma Rugosum (Asian Bullet Ants), Manjho Aron R. Broniola, Ethan Jay O. Dayandante, Patricia Erin D. Sotto, Lawrence P. Belo

DLSU Senior High School Research Congress Conference Proceedings

Ants showcase that size does not always matter. Through their small stature, they continue surviving in the land they live in, continuously being resourceful for their colony. Each ant serves their purpose of building, hunting, and growing their colony. They used their heightened senses to communicate danger, routes, and food sources from which they could contribute to the colony. Typically done via pheromones, also known as their “scent.” Previous studies have raised the preference of other ant species to be colors of short wavelengths. Now, this study deals with the ethology of ants, specifically regarding their foraging behavior, raising the …
