Turning English into a Second Language in Vietnam’s Education System: A Language Policy Analysis

/in /by

The year 2025 marks a critical turning point in Vietnam’s language education policy with the official approval of the national project to transform English into a second language within the education system. This paper critically examines the policy Making English a Second Language in Schools (2025–2035, Vision 2045) through Spolsky’s (2004) tripartite model of language policy, focusing on language ideologies, language management, and language practices. Drawing on policy documents, government resolutions, and secondary sources, the study situates the policy within Vietnam’s broader historical, sociopolitical, and sociolinguistic context of post–Đổi Mới reform and globalization. The analysis reveals that the policy is underpinned by a strong ideology of linguistic instrumentalism, positioning English as a key resource for national development, global integration, and workforce competitiveness. At the level of language management, the policy demonstrates ambitious, centralized planning through curriculum reform, teacher development, English-medium instruction, and digital transformation. However, language practices across educational contexts reveal persistent gaps between policy aspirations and classroom realities, particularly in rural and disadvantaged regions. Uneven teacher preparedness, infrastructural disparities, exam-oriented pedagogies, and emerging equity concerns challenge the sustainable implementation of English as a functional second language. The paper argues that while the policy represents a significant shift from foreign language education toward systemic bilingualization, its long-term success depends on contextualized implementation, teacher agency, and equitable resource allocation. Ultimately, English should function as an inclusive communicative resource rather than a gatekeeping mechanism, ensuring that national modernization does not exacerbate existing social and linguistic inequalities.

Customer Satisfaction in Airport Baggage Reclaim: Conceptualising a Moderated-Mediated Model of Service Quality and Risk Management

/in /by

This study conceptualises a moderated-mediation framework to explain customer satisfaction in airport baggage reclaim operations. Customer satisfaction is positioned as the dependent variable, with baggage reclaim handling process serving as the independent variable. Drawing on process improvement and service quality perspectives, the framework proposes service quality as a mediator through which baggage reclaim handling influences customer satisfaction. Efficient, reliable, and transparent baggage reclaim processes are expected to enhance perceptions of service quality, which in turn drive satisfaction. The framework further introduces risk management as a moderator, acknowledging the inherently uncertain and disruption-prone nature of airport operations. Operational risks such as system failures, congestion, and human error can weaken service consistency and undermine customer satisfaction, even when baggage processes are well designed. Effective risk management is therefore a contingency factor that strengthens the effect of the baggage reclaim handling process on customer satisfaction by stabilising service quality under varying operational conditions. Grounded in Process Improvement Theory, SERVQUAL, Expectation–Confirmation Theory, and Contingency Theory, the proposed model explains how operational efficiency translates into customer satisfaction through perceptual evaluations of service quality, while accounting for contextual risk conditions. The study integrates operational, perceptual, and contextual dimensions into a single explanatory framework and offers insights for highlighting the importance of aligning process optimisation with service quality management and robust risk mitigation strategies. The study concludes by encouraging future empirical research to test the proposed moderated-mediation relationships using multivariate statistical techniques and to support data-driven improvements in airport baggage operations and passenger experience.

Key Performance Indicators (KPIs) in Additive Manufacturing: Evaluation of Efficiency, Quality and Sustainability in 3D Printing Processes

/in /by

 As a researcher specializing in additive manufacturing (AM), I have authored this study titled “Key Performance Indicators (KPIs) in Additive Manufacturing: Evaluation of Efficiency, Quality, and Sustainability in 3D Printing Processes.” The work explores AM’s explosive growth, with the global market at 21.9 billion in 2025, projected to hit USD 647.7 billion by 2035 at a 22-23% CAGR, driven by innovations in materials, AI integration, and applications in aerospace, automotive, and biomedicine. AM transforms traditional manufacturing through on-demand production, waste reduction, and supply chain optimization, supporting circular economy principles via localized fabrication and emission cuts.

Utilizing the SALSA methodology, conducted a systematic review of 158 articles (narrowed to 10 key studies from 2015-2025), identifying AM-specific KPIs: efficiency (adapted OEE, varying with build variety); quality (tensile strength up to 55.2 MPa, dimensional deviation 0.048 mm); sustainability (energy consumption, recyclability challenges in PLA/ABS); costs; and delivery times.

Limitations include adapting traditional metrics to AM’s anisotropy and variability, plus unstandardized sustainability data. A pilot test on 10 parts across five hypothetical Hidalgo companies yielded averages like 74.4% OEE and 83.9% material efficiency, underscoring AI’s role in optimization. Ultimately, robust KPIs foster informed AM adoption, aligning with a SDGs 9 and 12 for resilient, sustainable industries.

Digital Era Tax Compliance: A Systematic Review Integrating Behavioral, Technological, and Institutional Perspectives

/in /by

Digital tax compliance has become central to public finance as governments increasingly adopt digital technologies to modernize tax administration and governance. This study systematically reviews research on digital tax compliance published between 2021 and 2025, with a focus on the intersection of behavioral, technological, and institutional factors. Employing the PRISMA 2020 protocol and the TCCM framework, 143 Scopus-indexed articles were screened, resulting in 38 studies selected for in-depth analysis. The findings indicate that digitalization is fundamentally transforming tax compliance by shifting from deterrence-based enforcement models to trust-based, voluntary compliance, supported by behavioral insights, technological advancements, and institutional legitimacy. The review identifies three primary thematic clusters: behavioral factors (tax morale, trust, fairness), technological factors (digital platforms, artificial intelligence, blockchain), and institutional factors (governance quality, transparency, tax literacy). The synthesis highlights digitalization’s contribution to enhancing efficiency and reshaping taxpayer behavior by improving legitimacy and motivation. However, the existing research remains fragmented and lacks comprehensive frameworks, with a predominant focus on emerging economies and limited longitudinal or mixed-method studies. This review contributes to the field by conceptualizing digital tax compliance as a behavioral, technological, and institutional nexus, and by positioning digital governance as a catalyst for voluntary compliance. The study provides policy recommendations for developing inclusive, trust-based digital tax systems and outlines a research agenda for the evolving digital tax landscape.

Knowledge and Attitudes toward Reproductive Health among Female Teacher Training Students: A Cross-Sectional Study in Nusa Cendana University

/in /by

Background: Reproductive health among adolescents and young adults remains a public health priority in Indonesia, including East Nusa Tenggara. Limited literacy and unfavorable attitudes increase risks of unintended pregnancy, risky sexual behaviors, and sexually transmitted infections (STIs). This topic is particularly salient for female students in the Faculty of Teacher Training and Education as future educators, while sociocultural norms and taboos can impede discourse.

Objective: To assess knowledge, attitudes, and their association regarding reproductive health among female students in the Faculty of Teacher Training and Education at Nusa Cendana University. Methods: An analytical cross-sectional study was conducted among 135 participants selected via cluster and stratified random sampling across nine programs. Data were collected using structured questionnaires on knowledge and attitudes. Univariate summaries and Chi-square tests (SPSS v30) were applied with a 0.05 significance level. Some cells in the contingency table had expected counts <5, violating the Chi-square assumption. Therefore, variable categories were collapsed, or an alternative test, such as Fisher’s exact test, was used for inferential analysis, and the effect size (Cramér’s V) = 0,564.

Results: Good knowledge was observed in 66.7% of respondents, moderate in 14.1%, and low in 19.3%. Positive attitudes were reported by 85.2% and negative by 14.8%. Knowledge level was significantly associated with attitudes (chi-square = 43.001; p < 0.001, Cramér’s V = 0.564, large). Sensitivity analysis by collapsing knowledge categories (moderate + low) confirmed robustness (Fisher’s exact p < 0.001; phi ≈ 0.55).

Conclusions: Higher knowledge is associated with more favorable attitudes toward reproductive health. Integrating comprehensive, culturally sensitive, and evidence-based reproductive health education within teacher-training curricula is recommended, with emphasis on digital literacy and curated information sources.

Perceived Behavioral Control Towards Tax Compliance Intention Among Local Micro-enterprises Owners

/in /by

This paper explored the interaction between perceived behavioral control and tax compliance intention on the local micro-enterprise owners in Poblacion, Impasugong, Bukidnon. Particularly, it examined the effects of the perceived behavioral control dimensiones on the degree of tax compliance intention on the basis of tax complexity, tax information, and tax awareness. These studies used descriptive-correlational research design in which a simple random sampling was done on 134 registered micro-enterprise owners. The validated adapted and modified questionnaire was used in gathering data and analysis was done by weighted mean and Spearman rho correlation. Findings showed moderate though significant knowledge on respondents regarding tax complexity (M=3.19) and high knowledge regarding tax information (M=3.34) and tax awareness (M=3.48), which creates an overall perceived behavioral control (M=3.34), meaning high. The general average of tax compliance intention (M=3.26) showed that the intention to comply was huge especially paying taxes accurately and on time. Correlation analysis revealed that there was a significant positive relationship between perceived behavioral control and tax compliance intention (r =.408, p <.001), implying that the higher the perceived behavioral control, the higher the compliance intentions. The research finds that the voluntary compliance among the owners of micro-enterprises can be helped by the simplification of the tax processes and access to the correct tax data. It suggests that the Bureau of Internal Revenue and other local policy makers should step up the campaign on taxes education, dissemination of digital information, and support services to promote increased compliance with tax laws and community building.
