Interdisciplinary approach in educational management science: Theoretical foundations and comparative analysis of the educational management program at the National Academy of Education Management, Vietnam

This study examines the interdisciplinary foundations of educational management science through a qualitative analysis of the undergraduate, master's, and doctoral programs in Educational Management at the National Academy of Education Management (NAEM), Vietnam. Drawing from both international theoretical frameworks and official curricula from 2024 to 2025, the research investigates how interdisciplinary integration is structured across academic levels and how it supports leadership, innovation, and sustainable development in education. The findings reveal that NAEM’s programs form a coherent vertical system based on seven thematic domains: management and leadership, systems science, economics and policy, sociology and organizational culture, improvement science, educational technology and data analytics, and global and transdisciplinary perspectives. The study shows that interdisciplinarity serves as both a theoretical foundation and a strategic framework linking theory, research, and practice in the professional development of educational leaders. The discussion emphasizes that the programs exemplify Mode 2 Knowledge Production (Gibbons et al., 1994), where knowledge emerges through the interaction of academic inquiry, professional practice, and policy contexts. The study concludes with recommendations to strengthen theoretical frameworks, promote interdisciplinary research networks, and expand international collaboration to enhance the global standing of Vietnam’s educational management science

The effect of investor sentiment on stock returns in Norway and Vietnam

Masteroppgave(MSc) in Master of Science in Business, Finance - Handelshøyskolen BI, 2014This study investigates the effects of investor sentiment on stock returns in the Norwegian and Vietnamese stock markets. The model introduced by Baker and Wurgler (2006) has been utilized in which a composite sentiment index has been constructed based on six proxies. Two additional proxies for investor sentiment, VIX and CCI, have been added in order to improve the estimating power of the sentiment index. Through establishing portfolios of different types of stocks, we found that the sentiment effect on returns is stronger for stocks that are hard to value and hard to arbitrage, i.e. small, high volatility, non-dividend-paying, and value stocks. Sentiment negatively predicts these types of stocks’ returns, i.e. when sentiment is low (high), future stock returns tend to be higher (lower). Particularly in Norway, when sentiment is high, subsequent returns are relatively low for small firms and unprofitable firms. In Vietnam, when sentiment is high, subsequent returns are relatively low for small firms and firms with highly volatile stock returns. And vice-versa. The results from a robustness test of the orthogonalized sentiment indices for Norway and Vietnam shows that the sentiment indices for Norway are sensitive to VIX whereas the sentiment indices in Vietnam show no pattern. This implies that VIX plays an important role when constructing the sentiment index in a developed stock market, i.e. Norway, than in an emerging stock market, i.e. Vietnam. CCI as a sentiment proxy can also forecast stock returns in Norway, however, its predictive power is not as strong as VIX

Key Factors Influencing Customer Satisfaction and Intention to Reuse Food Ordering Apps

This empirical study aims to identify and evaluate the crucial factors that influence customer satisfaction and their intention to reuse a food ordering app (FOA) in Ho Chi Minh City (HCMC), Vietnam. A data sample of 413 observations from customers who used the FOA was used to test hypotheses using a quantitative technique and a structural linear model. The results indicated that among the four key factors, performance expectancy, price value, and online reviews had direct and indirect effects on customers’ continued intention to use the FOA. By contrast, hedonic motivation only had an indirect effect. Satisfaction level was the mediating factor that affected customers’ continuance intention. This study provided insights into the online service and how the key factors affected customers’ satisfaction level towards the intention to reuse the FOA. When the management of the online providing service improves the key factors – performance expectancy, hedonic motivation, price value, and online reviews – they will improve the level of satisfaction towards the intention to reuse the FOA of customers in HCMC. The management of food companies should refer to this research model for restructuring and improving their business to satisfy the needs and wants of their target customers in the competitive market

Musculoskeletal Pain and Work-related Risk Factors among Waste Collectors in Hanoi, Vietnam: A Cross-sectional Study

BACKGROUND: Musculoskeletal disorders (MSDs) are prevalent among waste collectors (WCs) in developing countries. AIM: This study aimed to investigate the prevalence of MSDs and the factors associated with the risk of persistent musculoskeletal pain among WCs in Hanoi, Vietnam. METHODS: A cross-sectional survey was utilized to study 468 WCs in 2017. The Örebro Musculoskeletal Pain Questionnaire and a questionnaire on demographic and work conditions were used to collect data. Descriptive and multivariate logistics regression analyzes were applied at a significance level of 0.05 to examine the factors related to the risk of persistent pain. FINDINGS: About 74.4% of the participants of this study experienced MSDs in at least one body region and 9.4% reported MSDs in all 10 body sites. The lower back was reported to be the most affected followed by the neck and shoulders. The risk of persistent musculoskeletal pain was significantly associated with age (odds ratio (OR) = 2.31, confidence interval (CI) = 1.05–5.09), gender (OR = 3.29, CI = 1.28–8.44), work hours (OR = 2.35, CI = 1.12–4.92), work shift (OR = 0.48, CI = 0.26–0.92), duration of poor postures of the neck (OR = 0.31, CI = 0.13–0.76), bent back (OR = 0.4 CI = 0.18–0.92) and for medial rotation (OR = 3.01, CI = 1.42–6.36), carrying heavy objects (OR = 2.94, CI = 1.15–7.48), and experience of work dissatisfaction (OR = 3.31, CI = 1.46-7.52), stress (OR = 7.14, CI = 3.14–16.24), or anxiety (OR = 6.37, CI = 3.07–13.21). CONCLUSIONS: High prevalence of MSDs among WCs and its association with self-assessed unfavorable work postures and work-related stress implies the need of mechanical and social support at work for WC to prevent the development of MSDs and persistent pain

Novel Management Model for Leveraging Leadership for Successful Digital Transformation in Telecommunications Enterprises

Digital transformation (DT) is crucial for improving telecommunications efficiency and competitiveness. This study examines the role of change leadership in driving successful DT in Vietnamese telecommunication enterprises, focusing on its impact on employee engagement, employee commitment, DT communication, and DT capacity. A mixed-methods approach was employed, combining qualitative insights with quantitative data from surveys of management personnel overseeing digital transformation projects. Data were analyzed to assess direct and indirect relationships using structural equation modeling. The results indicate that change leadership is a significant driver of DT success with the strongest direct effect on employee commitment. Additionally, employee commitment and digital transformation communication positively influence success through their indirect effects on an enterprise’s DT capacity. Leadership plays a critical role in fostering commitment and aligning effort with DT goals. This study introduces a novel paradigm illustrating the interplay of various interrelated factors influencing the effectiveness of digital transformation, distinguishing it from previous studies that examined these factors in isolation. This approach provides novel insights, especially regarding Vietnamese telecommunications, a domain inadequately examined in previous studies on leadership-driven digital transformation initiatives

Contaminant spreading by natural convection in a box

In this paper the spreading of a contaminant accompanied  with natural convection in a box is numerically simulated. The box may be  considered as a cooking room or a working place where some sources of heat  and contaminant are in the simultaneous action. The box floor is supposed to  be divided into several domains with different boundary conditions for  temperature or heat flux. Here the purpose of the simulation is to  understand the contaminant spreading process in the box under the influence  of a convective motion. The model can be also applied for an enclosure with  separated parts differentially heated by the sunlight on its boundaries. A  good knowledge of this process is very useful for setting an efficient  ventilation scheme. In this paper the finite difference method based on the  Samarski scheme with ADI technique is applied for numerical simulation. Here  the box floor is divided into two domains of equal sizes but with different  temperature or heat flux. The contaminant source locates in the middle of  the box bottom. The simulation shows that over the part of the floor where  temperature or heat flux is greater the contaminant concentration is lager.  That result is in the accordance with the experiment done in the framework  of this~investigation

Heat Stress Affects Seed Set and Grain Quality of Vietnamese Rice Cultivars during Heading and Grain Filling Period

Environmental stress trigger a variety of rice plant response, ranging from alters seed set, grain yield and grain quality during flowering and grain filling stage.  Efforts are required to improve our understanding of the impact of heat stress on rice production, which are essential strategies in rice cultivation. This article investigated the seed set, yield components and grain yield of Vietnamese rice cultivars (Indica germplasm) under high temperature environment during the flowering and grain filling stage. Six rice cultivars, including popular cultivars and new cultivars of Cuu Long Delta Rice Research Institute, and one popular extraneous cultivar with differences in maturing time, were grown in pots at high temperature (HT) and natural temperature condition as control (CT). All rice cultivars were subjected to the high temperature starting from the heading stage to the harvest maturity, applied by greenhouse effect. The greenhouse has about 25 cm window opening on 3 sides for air ventilation. The seed set rate of the heat-sensitive rice genotypes decreased significantly under HT, leading to a significant reduction in grain yield. The lowest seed set was recorded in “OM4900” (44.3%) and “OM18” (39.9%) under high temperature environment. The lower yield in all rice cultivars at an elevated temperature resulted in a dramatic decrease of filled grains and contributed to a loss of 1000-grain weight. ‘“OM892” is a potential rice cultivar for heat tolerant breeding program due to the seed set percentage was above 80% in both HT and CT conditions. High temperature during the grain filling stage resulted in a decreased amylose and increased chalkiness for all OM cultivars
