Designing a workplace harassment reporting platform framework using sentiment analysis
(Institute of Electrical and Electronics Engineers Inc., 2026) Sardeng, Shekainah Kim A.; Palaoag, Thelma D
Subtle and multi-faceted workplace harassment can leave victims hesitant to report incidents. This study aims to design a workplace harassment reporting platform framework enhanced by sentiment analysis to better capture and understand employee experiences. The study adopted a systematic, iterative research design structured into three interconnected phases—data collection and gathering, data analysis, and framework design —to develop a comprehensive workplace harassment reporting platform framework using sentiment analysis. The methodology combined an initial literature review on harassment systems, reporting platforms, and sentiment analysis with in-depth document analysis of organizational policies, HR workflows, and technical options, alongside the development and refinement of a design prototype specifying user roles, reporting flows, and dashboard-based monitoring. Insights and drawbacks identified through these analytic and design activities were fed back into an iterative framework construction process, ensuring that the final platform framework is theoretically grounded, operationally feasible, and capable of integrating sentiment analysis for prioritizing and managing harassment reports. The designed framework provides a structured yet flexible platform that integrates sentiment analysis to enhance the detection and interpretation of both explicit and implicit harassment reports. The framework supports multiple reporting channels, ensuring immediate accessibility and confidentiality for victims, while enabling organizations to monitor incidents in real-time through automated emotional cue analysis and thematic categorization. The established framework supports the formulation of timely and context-appropriate organizational interventions predicated upon the resulting sentiment insights, thereby positioning the integration of sentiment analysis within a harassment reporting platform as a promising solution to improve the detection and effective monitoring of workplace harassment.
Diversity, characteristics, and altitudinal distribution of pteridophytes in Manleluag Spring Protected Landscape (MSPL), Mangatarem, Pangasinan, Philippines
(Prince of Songkla University, 2026-02) Aban, Jomar L.; Fajardo, Weenalei T.; Maddumba, Helen A.; Bawingan, Paulina A.
The Manleluag Spring Protected Landscape (MSPL) was included among protected areas under the NIPAS Act of 1992. It covers 12% of the forestlands of Mangatarem, Pangasinan, which harbors some endemic unique and threatened species of plants and animals, including ecologically important Pteridophyte species. The undisputed ecological and economic contributions of the pteridophytes at the global and local scale were the basis for the conduct of this study. It aimed to identify the different Pteridophyte species present in selected forest sites of MSPL; to prepare voucher herbarium specimens as inventorymaterials for future conservation purposes; to determine Pteridophyte zones based on different altitudinal zones; and to assess and compare the species richness, evenness, and diversity of the different sites at MSPL. Fourteen fern species under seven (7) genera and five (5) families were collected, identified, and classified, constituting 1.35% species richness, 4.86% genera richness, and 12.82% familial richness compared to the total Pteridophyte richness in the Philippines. The biodiversity and species richness were relatively low due to several dominant Pteridophyte species in the different study sites and the classification of Manleluag as a secondary forest by the Haribon Foundation. Pteridophyte zones were also observed. Some families dominated low altitudes, some preferred mid-altitudes, and others favored high altitudes. The researchers highly recommend intensified implementation of the Manleluag Spring Protected Landscape (MSPL) management plan and continuous monitoring of the diversity and abundance of different Pteridophyte species.
The strategies behind the PhD in Mathematics Education Graduates' Professional Growth:
(City University of New York, 2026) Cerveza, Ryan L.
This study explored the professional growth of PhD in Mathematics Education graduates from Don Mariano Marcos Memorial State University (2016–2023), focusing on the teaching strategies that contributed to their advancement. Motivated by the limited research linking doctoral training to practical classroom application, the study aims to identify which instructional approaches were most relevant to graduates’ teaching practices and career outcomes. Using a descriptive tracer study design, data were gathered from all 16 program alumni through a structured online survey and analyzed using both quantitative and qualitative methods. Findings revealed that research-based instruction, problem-based learning, and digital tool integration were the most impactful strategies, contributing to improved teaching performance, increased confidence, job promotions, and professional recognition. Graduates reported high alignment between their doctoral training and real-world educational demands, particularly during the pandemic’s transition to remote learning. Framed by Human Capital and Social Systems Theories, the results highlight how doctoral education functions as both a personal investment and an institutional lever for change. The study concludes that embedding flexible, research-informed pedagogies in doctoral programs strengthens instructional leadership and positions graduates as key agents of innovation in mathematics education.
Mycochemical Composition, Antioxidant Properties, and Cytotoxic Activity of Xylaria papulis Lloyd (Xylariaceae) Mycelia Grown in Static and Shaking Indigenous Liquid Culture Conditions.
(Research and Innovation Department,Khon Kaen University, Thailand, 2026-05) Lopez, Mark Kevin S.; Kalaw, Sofronio P.; Dulay, Rich Milton R.; De Leon, Angeles M.; Reyes, Renato G.
The search for promising and sustainable sources of secondary metabolites with potential biofunctional activities is important for the possible sources of drugs to treat human diseases. Hence, this study qualitatively assessed the mycochemical composition and investigated the biofunctional activities (antioxidant activity and cytotoxic activity) of Xylaria papulis Lloyd mycelia grown in static and shaking indigenous liquid culture medium. Mycochemical screening revealed the presence of several classes of secondary metabolites, such as phenolics, terpenoids, fatty acid derivatives, alkaloids, and sugar derivatives, in mycelial mat (shaking) and in culture spent (static). Mycelial mat (static) and culture spent (shaking) also contain the same classes of secondary metabolites, with the former including essential oils. Mycelial extracts have greater antioxidant property (≤ 43.19±1.63% RSA) and total phenolics (≤ 47.75±2.31 mg/GAE) compared to the culture spent. Culture spent from shaking condition exhibited cytotoxicity (LC50 = 94.39µg/mL) against brine shrimp larvae. These findings indicate that X. papulis (Lloyd) grown in liquid culture medium can be a sustainable source of diverse secondary metabolites with antioxidant properties and cytotoxic activity. Further, cytotoxicity studies against cancer cell lines can also be investigated for future studies.
Advancing sustainable agriculture through beneficial microbes:
(Research and Innovation Department,Khon Kaen University, Thailand, 2026-05) Aban, Jomar L.; de Guzman, Allen Dale L.; Escobal, Mark Joseph B. ; Estal, Karen Nicole F.; Milanes, Nathanael Alexis S.; Sagun, Analyn V.
This is a review of the use of effective microorganisms (EM) in sustainable agriculture to improve soil quality, increase crop yields, and control plant diseases. This review aims to contribute to understanding sustainable agriculture using microbes for our benefit by integrating microbial physiology and synthetic microbial innovations, with respect to community-level microbial interactions. Using a literature search strategy, the physiological mechanisms by which EM may enhance soil fertility through improved nutrient cycling and increased nutrient availability to plants, and/or by creating or modifying soil structure to support root growth, were described. Results showed that EM also increase the ability of plants to grow despite biotic stressors, such as soil-borne pathogens, through both the creation of antimicrobial compounds and competitive exclusion. Microbes also enhance plant tolerance to abiotic stressors, such as water loss from drought or salt accumulation, by altering how plants respond physiologically and by retaining soil moisture. This could be achieved by using effective microbes in agriculture via synthetic microbial communities (SynCom), which will enable greater resource efficiency, a lower environmental footprint, and contribute to achieving food security while addressing current global issues such as climate change and growing populations. However, there is still much to be learned about the long-term ecological implications, scalability, regulatory environments, and socio-economic feasibility of agricultural technologies based on microorganisms and SynComs, especially in developing and climate-vulnerable countries. Therefore, a comprehensive review that links microbial physiology, SynCom design, empirical data from crop studies, and future paths to innovation is both timely and needed.
