type: item
description: Financial risk management serves as a vital element for organizational stability which becomes essential for organizations that face multiple regulatory and market and operational uncertainties. Organizations implement MIS together with accounting practices to track and reduce financial risks but their performance and organizational impact need thorough evaluation. This study collected data from 310 professionals who worked in finance and banking and manufacturing and healthcare and retail industries. FRM difficulties together with MIS operations and accounting systems and their combined influence on business results. This study used descriptive statistics to describe participant demographics together with organizational features and employed Pearson correlation and regression analysis to detect connections between FRM, MIS, ACC, INT and BP. The survey results revealed that regulatory compliance at 55.2% and market volatility at 52.6% emerged as the primary financial risk challenges according to the participants. Management information system functions reporting accuracy (59.1%) and real time data availability (57.4%) were identified as the most effective. Pearson correlations revealed that FRM, MIS, ACC, INT and BP share moderate to strong positive connections yet integration stands out as the most influential factor for performance results (r = 0.74, p = 0.01). This study demonstrates that organizations achieve better financial risk management and performance results through effective MIS systems and accounting practices which need to work together as integrated units. Integration of these systems enables management to match risk indicators with performance metrics which leads to better and faster strategic decision-making.

The impact of Artificial Intelligence (AI) applications on teaching quality and learner satisfaction at foreign language centers in Ho Chi Minh City
type: item
description: In the context of the strong educational digital transformation, mastering digital platforms and the application of Artificial Intelligence (AI) at foreign language centers in Vietnam, especially in Ho Chi Minh City (HCMC), is becoming an inevitable trend. Many nations globally have identified education as a top priority sector for AI application. In the United States, according to the 2024 educational technology report, 60% of teachers use AI tools in teaching management. In South Korea, since 2023, the Ministry of Education has piloted the use of AI for primary school students and recorded that 30% of students achieved effectiveness in personalization. In Vietnam, the Ministry of Education and Training is implementing two crucial projects: one involves digital transformation and AI application in teaching and learning; the second is to establish English as the second language in schools. However, quantitative studies assessing the impact of AI on teaching quality and learner satisfaction at foreign language centers in HCMC remain limited. This research will construct and propose a Structural Equation Model (SEM) to test the relationship between AI application, teaching quality, and learner satisfaction. Drawing upon the SERVQUAL theory, TAM, and international research on AI in education, the study proposes four hypotheses regarding the direct and mediating effects among the variables. The paper is expected to provide a crucial reference framework for foreign language centers in their strategy to integrate AI into teaching effectively, humanely, and sustainably.

Socratic Political Heritage - Ethical Challenges and the Role of Dialogue in Contemporary Society
type: item
description: Western philosophy has failed to find a successor to Socrates in political and ethical thought. Contemporary political ethics and civic engagement debates would still depend on his commitment to questioning, moral inquiry, and civic engagement. This paper portrays Socrates' political heritage in terms of ethical challenges and the dialogue as a means for dealing with the modern sociological predicament. It examines how the works of 20th-century philosophers such as Hannah Arendt, Michel Foucault, and Hans-Georg Gadamer reveal that the living Socratic principle is as much of a problem to be solved. This research paper evaluates the Socratic dialogue's role in resisting authoritarianism and developing democratic deliberation in contemporary politics. Finally, the paper affirms that Socratic ethics, concentrating on self-examination and critical dialogue, continues to be a strong instrument for working out contemporary political and ethical difficulties.

The Impact of Basel II Regulations on Firms' Access To Credit: Empirical Evidence From Asian Countries
type: item
description: This study evaluates the impact of Basel II on corporate credit access based on credit ratings, using panel data of 1,295 firms across 17 Asian countries from 2004-2015. System GMM estimation results show that after Basel II implementation, firms with high credit risk (rated BB- and below) experienced a 19.94%-23.30% reduction in credit access compared to higher-rated firms. The study also finds that factors such as operating cash flow, financial leverage, and revenue size significantly impact firms' borrowing decisions in the Basel II context. Based on these findings, the author proposes policy implications including establishing a government credit guarantee system, adjusting risk weights appropriate to Asian market characteristics, reforming the credit rating system, and encouraging banks to develop internal risk assessment capabilities.

Integration of Nanomaterial-Based Filtration and Smart Gas Sensing Systems for Enhanced Safety in Aviation Maintenance Environments
type: item
description: Maintenance workers in aviation constantly work with dangerous substances like hydrazine, JP-8, and AVGAS. The exposure to these chemicals over a long period of time can lead to the development of serious health problems. The current safety regulations in the field are still inadequate to provide complete protection for the workers during refueling and maintenance activities. This study explores how wearable technologies equipped with nanomaterial filters and gas detection sensors can improve both safety and productivity in the aviation industry. Nanomaterials such as graphene, carbon nanotubes (CNTs), and titanium dioxide (TiO₂) provide superior filtration performance because of their large surface area and ability to neutralize toxic compounds. In combination with electrochemical and metal-oxide sensors, these systems can continuously monitor air quality and instantly alert users when harmful gases are detected. The literature review and the available technologies are the major sources of information that this paper uses to justify the benefits of hybrid systems in aviation workplaces in terms of safety, efficiency, and eco-friendliness. It also presents the challenges that are still faced in the areas of weight, power consumption, and reliability over the long term, which are the reasons for the small-scale adoption. The main point is that when one combines nanomaterial filtration with advanced detection technology, the result will be a great reduction of occupational hazards and the increase of aviation safety equipment's lifespan.

ENHANCING STUDENTS’ ENGLISH ORAL COMMUNICATION SKILLS THROUGH ROLE-PLAY ACTIVITIES: A CASE STUDY AT HANOI UNIVERSITY OF NATURAL RESOURCES AND ENVIRONMENT
type: item
description: Abstract: Developing oral communication competence remains a persistent challenge for Vietnamese university students, particularly among non-English majors who often exhibit limited fluency despite years of instruction. This study investigates the effectiveness of role-play activities in enhancing students’ English speaking skills at Hanoi University of Natural Resources and Environment (HUNRE). A quantitative case study design was employed with 56 first-year students at the A2 CEFR level. Data were collected through pre- and post-intervention speaking tests, assessed with an adapted analytic rubric, and a post-intervention questionnaire. Findings revealed a statistically significant improvement in students’ speaking performance after an eight-week intervention (t(55) = -5.16, p < .001), with mean scores increasing from 7.02 to 7.35. Questionnaire results further indicated that students perceived role play as engaging, motivating, and beneficial for vocabulary development and communicative confidence. However, challenges such as limited vocabulary, insufficient background knowledge, time constraints, and nervousness were also reported. The results highlight the dual nature of role play: while it fosters measurable gains in oral proficiency, its effectiveness depends on appropriate scaffolding, contextual preparation, and sufficient classroom time. The study contributes empirical evidence on role play in tertiary EFL contexts, offering practical implications for curriculum design, teacher training, and the integration of communicative tasks in general English courses. Future research should explore long-term effects and technology-enhanced role play to broaden its pedagogical impact.

Advertising as a Linguistic Tool: A Syntactic Study of English and Vietnamese Brand Slogans
type: item
description: Advertising slogans are one of the most influential tools for building brand identity and attracting consumer attention in today’s competitive market. Despite their widespread use, many marketing professionals continue to face challenges in crafting effective slogans, often leading to weak associations between brands and their slogans. This study aims to investigate the distinctive syntactic features of English and Vietnamese advertising slogans, with the purpose of identifying both similarities and differences between the two languages. A descriptive and comparative research design was employed, analyzing a corpus of advertising slogans collected from English and Vietnamese newspapers and magazines. The findings reveal that slogans in both languages frequently employ simplicity, brevity, and elliptical structures—such as noun phrases, adjective phrases, and verb phrases—though English slogans show a greater tendency toward ellipsis and dynamic expressions. Additionally, repetition at the syntactic level emerges as a significant device in both languages, enhancing memorability and persuasive power. These results provide valuable implications for teaching and learning business English, offering learners and teachers deeper insights into the linguistic mechanisms of advertising language. Furthermore, the study proposes practical guidelines for advertisers and copywriters to design effective slogans that strengthen brand recognition and consumer engagement.

Reinforcement Learning for Autonomous Data Pipeline Optimization in Cloud-Native Architectures
type: item
description: Efficient data pipeline management is critical for cloud-native architectures, where data velocity, volume, and variety challenge traditional orchestration methods. This study proposes a Reinforcement Learning (RL)-based framework for autonomous optimization of data pipelines, enabling dynamic task scheduling, resource allocation, and failure recovery without human intervention. The framework models pipeline operations as a sequential decision-making problem, where an RL agent learns optimal policies to maximize throughput, minimize latency, and reduce operational costs. Experiments conducted on simulated and real-world cloud-native workloads demonstrate that the RL-optimized pipelines achieve significant performance improvements compared to conventional static and heuristic-based scheduling strategies. This approach highlights the potential of intelligent, self-adaptive data pipelines for scalable, resilient, and cost-efficient cloud-native data processing.

Federated Reinforcement Learning for Adaptive Fraud Behavior Analytics in Digital Banking
type: item
description: The rapid growth of digital banking has been paralleled by increasingly sophisticated fraud attempts that adapt to detection mechanisms. Traditional centralized fraud detection models often face challenges such as data privacy concerns, scalability limitations, and delayed adaptability to emerging fraud patterns. To address these issues, this study proposes a Federated Reinforcement Learning (FRL) framework for adaptive fraud behavior analytics in digital banking. The framework enables multiple financial institutions to collaboratively train fraud detection agents without sharing sensitive customer data, thereby preserving privacy and regulatory compliance. By leveraging reinforcement learning, the model continuously adapts to dynamic fraud strategies through feedback-driven policy optimization. Experimental results demonstrate that the proposed FRL approach achieves superior detection accuracy, reduced false positives, and faster adaptation to novel fraud patterns compared to conventional machine learning and federated learning baselines. This research highlights the potential of FRL as a scalable and privacy-preserving solution for combating financial fraud in the era of decentralized and intelligent banking ecosystems.

Performance-Based Governance of Trade Corridors: Designing a Balanced Scorecard Integrating the TCEI Dimensions
type: item
description: Within the boundaries of the current paper, it is suggested that performance-based governance of trade corridors should be approached with an incorporation of the three dimensions of the Trade Corridor Efficiency Index (TCEI) which includes time efficiency, infrastructure quality and geopolitical risk into a Balanced Scorecard model. The framework makes use of these dimensions of TCEI and converts them into strategic Key Performance Indicators (KPIs) to evaluate and enhance the performance of trade corridor governance. Through real-life case studies and the simulation model, the research identifies how the proposed model can make the infrastructure more efficient, align policies, and make up the resilience in geopolitically and infrastructural affected corridors. The results prove the applicative power of the TCEI-based Balanced Scorecard to serve as a decision-making tool, help to detect gaps in the performance, and inspire the specific investment. The study provides a unique instrument the policymakers and the logistics entities can use to evaluate the performance of trade corridors and the enhancement of global trade environment.

AI-Agent Driven Test Environment Setup and Teardown for Scalable Cloud Applications
type: item
description: The increasing complexity of cloud-native and distributed applications has intensified the need for efficient, scalable, and automated testing environments. Traditional manual or script-based test environment setup and teardown processes often struggle to keep pace with rapid deployment cycles and dynamic infrastructure changes. This paper proposes an AI-agent–driven framework that automates the provisioning, configuration, and dismantling of test environments in cloud ecosystems. Leveraging machine learning for resource optimization and intelligent orchestration, the AI agents dynamically allocate computing resources, configure application dependencies, and execute teardown procedures to minimize cost and idle time. The framework supports integration with popular CI/CD pipelines, enabling seamless scaling for multi-tenant and high-availability applications. Experimental evaluations demonstrate significant reductions in environment setup time, operational overhead, and infrastructure costs, while improving testing reliability and repeatability. The proposed approach offers a robust, adaptive solution for organizations aiming to accelerate development cycles without compromising quality in scalable cloud application testing.

Applying TBLT and The PERMA Model in Teaching Business English
type: item
description: Nowadays, Artificial Intelligence has placed a dominant role in teaching and learning English, which raises the question if AI will be able to replace the role of a teacher in the classroom. Facing those challenges, the teachers are supposed to do things differently based on their own contexts. Therefore, the researcher has applied TBLT and the PERMA model of flourishing (Positive emotions, Engagement, Relationships, Meaning, and Achievements) in designing meaningful tasks such as modified tasks, games, and speaking videos in teaching ESP. The tasks are required to meet some criteria including cognitive engagement, social engagement and affective engagement. At University of Economics Ho Chi Minh City in Vietnam, 170 students who major in Business Studies at intermediate level participate in the research during 90 hours for two semesters. Data collected from the observation and the questionnaire proves that this model has brought many benefits to the students in terms of learning outcomes as well as positive emotions in the learning performance. The results show more cognitive engagement, social engagement and affective engagement, particularly during the more complex tasks.

Levitate or Stagnate: A Comparative Review of Maglev Implementation in China, Japan, and India
type: item
description: This paper compares high speed Maglev systems in China, Japan and India, focusing on the interplay between infrastructure costs, technology maturity and policy frameworks. Shanghai’s EMS based Maglev is a short term, state funded demonstration project with limited ridership and no network integration. Japan’s SCMaglev is a long term, scalable national infrastructure project with strong public private partnerships and phased implementation. Using operational data, cost estimates and national transportation plans we explain why China’s system did not scale, how Japan is preparing for long term resilience and return on investment (ROI) and whether India is strategically and institutionally prepared for Maglev adoption. We assess India’s position in this spectrum by looking at proposals like Mumbai-Pune and Delhi-Agra corridors in the context of land acquisition hurdles, fiscal constraints and technological readiness. The paper also looks at emerging opportunities like AI assisted grid management, modular Maglev fabrication and room temperature superconductors (RTSCs) as enablers of future viability. Governance models – centralized vs hybrid PPPs are analysed to highlight the role of institutional continuity and policy coherence. Despite technical advancements, challenges in energy demands, infrastructure integration and governance slow down Maglev scalability. Our study concludes with a framework for India’s pilot scale deployment and a future ready roadmap aligning Make in India with high speed mobility.

Federated Data-Mesh Quality Scoring with Great Expectations and Apache Atlas Lineage
type: item
description: The proliferation of decentralized data architectures like data-mesh introduces challenges in maintaining consistent data quality across federated domains. This research proposes an integrated framework for federated data quality scoring by leveraging Great Expectations (GE) for declarative data validation and Apache Atlas for lineage-driven impact analysis. The solution enables domain teams to autonomously define quality rules using GE, while Apache Atlas captures end-to-end lineage to propagate quality scores across interconnected datasets. This lineage-aware approach quantifies quality degradation risks downstream, providing a holistic view of data health in a decentralized ecosystem. Experimental results demonstrate a 40% reduction in root-cause analysis time and a 35% improvement in cross-domain trust scores. The framework supports scalable, domain-agnostic quality monitoring without central oversight, aligning with data-mesh principles of decentralization and domain ownership.

Consent-Driven Continuous Delivery with Open Policy Agent and Spinnaker
type: item
description: Continuous Delivery (CD) pipelines require robust governance to balance automation with compliance, security, and auditability. Traditional manual approval processes introduce bottlenecks, while static policy enforcement lacks flexibility. This research introduces a consent-driven CD framework integrating Open Policy Agent (OPA)—a declarative policy engine—with Spinnaker, a leading open-source CD platform. The framework leverages OPA's dynamic policy-as-code capabilities to automate deployment consents based on contextual rules (e.g., security scans, environment risks, or regulatory requirements). By decoupling policy logic from Spinnaker's orchestration, our approach enables granular, auditable, and real-time consent decisions without halting pipelines for human intervention. We validate the solution through a case study demonstrating reduced deployment latency by 65%, elimination of manual approval backlogs, and consistent enforcement of organizational policies. The integration establishes a scalable, compliant CD workflow adaptable to evolving operational demands, proving that policy-driven automation enhances both velocity and governance in modern DevOps environments.

AI-Powered Crisis Management: Revolutionizing Customer Service Emergencies
type: item
description: This study examines the potential of AI as a disruptive technology to address brand crisis customer service by specifically analyzing the ability of AI to deliver personalized, real-time responses that can enhance customer perceptions of a firm’s handling of a crisis situation. The research design employed online surveys, semi-structured interviews with customer service workers, a controlled experiment, and a secondary analysis of cases in a mixed-methods study. Among the most relevant conclusions, Artificial Intelligence has been proven to be able to reduce response times to initial crisis responses while adding a personalization capability driven by data. For basic requests, AI can offer immediacy such that information queries are not provided. They also highlight the ongoing need for human intervention in emotional and complex situations where empathy and nuances are key. This study indicates that an optimum level of customer satisfaction is achieved using a hybrid human interaction model. This study is limited by its narrow focus on specific AI technologies, relatively small sample size, lack of demographic diversity, and dependence on a simulated crisis environment. Practice implications indicate that the role of AI in mobilization should involve providing this type of information, an initial point of contact that can be reached quickly, and clear and easy pathways for moving problems to a human who can handle more complexity. Its value lies in informing companies of useful practical implications in organizing responses to disasters and building trust in AI. Keywords: Artificial intelligence, crisis management, customer service, brand crisis, emergency response, customer satisfaction, natural language processing, chatbots, sentiment analysis, personalized communication.

Geo-Techno Politics and E-Commerce in the BRICS Countries:
type: item
description: E-commerce, the digital exchange of goods and services, is vital in shaping global trade. Its implementation varies significantly across the BRICS nations due to the differences in technological advancement, political structures, and economic development. Investigating how these disparities influence the geopolitical dynamics of the digital economy is coined by the term Geo-Techno politics, yet the impacts are rarely mentioned. While e-commerce promises increased connectivity and innovation, contrasting regulatory approaches such as Russia's Data Localization Law and Brazil's relatively open market demonstrate deep-rooted tension in digital cooperation. Using comparative policy analysis and review of government frameworks, this study explores how state-driven agendas, data sovereignty, and inconsistent consumer protections contribute to the growing mistrust between nations and consumers and hinder the development of a unified global commerce framework. The results show that while all BRICS countries have made great strides in the development of e-commerce, diverging national priorities and regulatory models create friction in cross-border trade, affect consumer confidence, and limit collaborative innovation. This fragmentation amplifies global political divisions and highlights the need for harmonized digital policies. By identifying the geopolitical consequences of disjointed e-commerce ecosystems, this study calls for strategic cooperation among BRICS nations to develop aligned frameworks that promote trust, interoperability, and sustainable growth.

Adapting Agile Methodologies to Incorporate Digital Twins in Sprint Planning, Backlog Refinement, and QA Validation
type: item
description: Agile approaches, which offer flexibility, iterative development, and constant feedback, have emerged as the mainstay of contemporary software and hardware development. However, managing dependencies, correctly forecasting system behavior, and evaluating features under real-world circumstances are all difficult tasks for traditional agile approaches. Real-time simulations, predictive analytics, and automated testing are made possible by digital twins (DTs), which are virtual representations of digital or physical systems. The three essential agile processes of sprint planning, backlog refinement, and QA validation are examined in this paper along with how DTs might improve them. By adopting Digital Twins, Agile teams may achieve more exact sprint predictions, risk-based backlog prioritization, and automated QA validation. DTs' capacity to model task allocation and foresee system restrictions helps in sprint planning. DT-driven dependency analysis and dynamic risk assessment enhance backlog refinement, guaranteeing that priority is in line with practical viability. Lastly, by offering virtual testing environments that identify flaws before to deployment, digital twins transform QA validation. This study synthesizes insights from existing literature, industry case studies, and empirical evidence to propose an integrated Agile-Digital Twin framework. The findings suggest that organizations implementing DTs within Agile practices experience enhanced efficiency, reduced technical debt, and improved product quality. However, challenges such as high implementation costs, integration complexity, and skill gaps must be addressed. The paper concludes by highlighting future research directions, including AI-powered Digital Twins for Agile optimization and the role of DTs in DevSecOps.
