Hongoy, Bai Ashfahana A. Abdullah, Ma. Sofia Franchesca P. Dizor, Leo James M. Podador, Joshua Caleb G. Pagalan, Ralph Laurence Valdueza

DLSU Senior High School Research Congress Conference Proceedings

With rising concerns over climate change and its impacts, this study develops and evaluates a Vector Autoregressive (VAR) model to forecast climatological data in General Santos City: surface pressure, specific humidity, wind speed, air temperature, precipitation, UVA and UVB irradiance, with data from January 1, 2001 to June 30, 2024. Mean hour calculations confirmed seasonality via the QS test (p < 0.001) for all variables except precipitation; Mann-Kendall tests indicated significant trends for all tested variables, and UV irradiances were the only variables with no significant long‐term trend. The Augmented Dickey-Fuller Test (p < 0.001) established stationarity of variables, and Granger‐causal relationships were identified. Results indicated a bidirectional Granger-causal relationship between variable pairs (p < 0.001). The AIC-based model selection identified VAR(168) as the best-fitting model, effectively capturing cyclic patterns up to one week. The residuals passed the Ljung-Box tests for no residual autocorrelation (p > 0.05), and OLS-CUSUM plots indicated structural stability. Mean root-mean-square error determined out-of-sample forecasting accuracy to be good for most variables, and poor for UVA and UVB irradiance; therefore, while the VAR(168) model does generate accurate forecasts, it still presents challenges. …

“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.

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.

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. …
