Abstract

Purpose

The effectiveness of full passive wind turbine (WT) systems has been recently demonstrated. Such low cost and reliable structures without active control and with a minimum number of sensors can be efficient only if the system design parameters are mutually adapted through an integrated optimal design approach. The purpose of this paper is to analyze the effectiveness of a passive WT with regard to the variations of PMSG electrical parameters.

Design/methodology/approach

This work is more specifically devoted to the sensitivity analysis of a passive WT system according to the electrical variable variations of a Permanent Magnet Synchronous Generator (PMSG). It also investigates the interest of a robust design approach for reducing the sensitivity of the WT efficiency to the most influencing variables.

Findings

It is shown that efficiency of the passive WT system is rather sensitive to the variation of the stator flux and DC voltage at the system output.

Originality/value

A robust design approach is investigated in order to reduce the passive WT sensitivity to the stator flux and DC voltage variations.

Abstract

This chapter provides information on the development of Vietnamese education under the influence of global forces based on the analysis of relevant education research and policies using Wolhuter’s frameworks. In the process of coming up with ways to develop education in the face of different influences of globalization, besides having reactions with patterns commonly found in countries around the world, Vietnam also has responses that reflect its own political, sociocultural and economic characteristics. The state still plays a controlling role in education at all levels and many culture-related features that have existed throughout the country’s history have hardly changed, namely aspects related to teachers, learners and teaching and learning methods. To sustain its education in the globalized era, Vietnam must make more efforts in various aspects such as the link between education and employment, the logic of education objectives, the feasibility and appropriateness of curricula, quality of education, especially of higher education and equality in education for underprivileged groups.

Abstract

Purpose

The Vietnamese Mekong River Delta (VMD) is one of the most affected deltas by climate change in the world. Several studies have investigated factors influencing farmers' climate change adaptation behaviors in the region; however, little is known about the effectiveness of such measures. This paper examines the determinants of adaptation strategies among VMD rice farmers and assesses the impacts of such practices on rice yield.

Design/methodology/approach

Endogenous switching regressions were employed using a survey data of 300 rice-producing households in An Giang and Tra Vinh provinces in 2016.

Findings

The results show that farmers receiving early disaster warnings are more likely to adopt adaptation measures to climate change. If nonadaptors had chosen to respond, their rice yield would have increased by 0.932 tons/ha/season.

Research limitations/implications

The data sample is small and collected from two provinces in the VMD only; therefore, the results may be specific for the study sites. However, future research can adopt the proposed method for other regions.

Originality/value

The study estimates the production impacts of farmers' decisions on whether or not to adapt to extreme climate events. The proposed approach allows for capturing both observed and unobserved behaviors.

Abstract

Purpose

This study aimed to examine the impact of learning organization (LO) on job satisfaction and individual performance in Vietnamese enterprises. The study further explores the mediating effect of job satisfaction on the relationship between learning organization and employee performance.

Design/methodology/approach

Data were collected from 653 employees from various types of organizations in Vietnam. Structural equation modeling was implemented to test the hypotheses.

Findings

The results revealed that the proposed research model was supported. Results indicated that LOs positively influenced employees’ job satisfaction and the broader range of their individual performance. In addition, employees’ job satisfaction motivated them to achieve higher performance levels. The study also found a mediating effect of job satisfaction on the relationship between LO and employee performance. The results underscore the importance of implementing an LO culture for individual outcomes such as job satisfaction and employee performance in the Vietnamese cultural context, which is based on socialism and Confucianism.

Originality/value

To the best of the authors’ knowledge, this is the first study to examine the relationships among LO, job satisfaction and individual employee performance in the Vietnamese context. The results offer a deeper understanding of the LO concept in the Vietnamese cultural context and highlight the cultural impact on the LO concept and its effects. The results suggest how the LO concept is applied in the Vietnamese context.

Abstract

This chapter clarifies the “dark tourism” in Vietnam; a case study of Hoa Lo Prison Relic. Development orientation of “dark tourism” in Vietnam contributes to healing the wounds of war. The author mainly uses a system approach, method of analysis and synthesis, and method of comparison. “Dark tourism” in Vietnam has not really developed as a specific type of tourism like ecotourism or meetings, incentives, conferences, and exhibitions (MICE) tourism. At Hoa Lo Prison historical site, “dark tourism” has been effectively exploited: (1) in the first 6 months of 2023, Hoa Lo Prison welcomes nearly 295 thousand visitors, charging fees of 7 billion VND, the situation of “sold out” takes place regularly; (2) many unique tourism products, one of the successful and widespread tourism products must be mentioned the “night tour” experience; (3) many creative forms of sightseeing with automatic explanation system so that visitors can experience 35 historical stories in their own way; and (4) always create the best conditions for visitors’ sightseeing experience. To promote dark tourism in Vietnam, it is necessary to execute some schemes: (i) enhance the sense of responsibility for peaceful tourism in the operation of monuments; (ii) stakeholders coordinate the organization of the tour program and tourist routes with appropriate contents and forms for each target group, especially foreign tourists; (iii) there is cooperation between national and international experts in organizing the “dark tourism” program aimed at peace, preventing the risk of war and conflict, and overcoming the consequences of war; and (iv) application of scientific and technological achievements in “dark tourism” activities.

Abstract

Purpose

This study aimed to utilize Epistemic Network Analysis (ENA) for a thorough evaluation of policy documents concerning the digital transformation in Vietnam's higher education sector.

Design/methodology/approach

Adopting a quantitative ethnography approach, this research employed ENA to analyse a curated collection of 21 documents that specifically addressed higher education (HE) and digital transformation within Vietnam. The study also incorporated qualitative content analysis, utilizing the constant comparison method as outlined by Onwuegbuzie et al. (2009), for data coding. ENA facilitated the examination of connections among various policy aspects.

Findings

The study revealed a consistent overarching theme in Vietnam's digital transformation policies during and post-pandemic, focusing on key areas such as ADMINISTRATION, VISION, QUALITY, and INFRASTRUCTURE. However, a temporal shift in emphasis was observed: during the pandemic, policies were more focused on ADMINISTRATION and INFRASTRUCTURE, while post-pandemic, there was an increased emphasis on COLLAB, VISION, and TEACH_LEARN.

Originality/value

This research represents one of the initial efforts to showcase the utility and significance of ENA in analysing policy documents. It underscores ENA's potential in elucidating the complex interplay of policy elements in the context of digital transformation in higher education, particularly within a developing country setting.

Abstract

Purpose

Drawing from emotional labour (EL) and emotion regulation (ER) theories, this paper aims to identifiy what helps and what hinders the emotional intelligence (EI) practice of Vietnamese hotel workers. Researching EI qualitatively from a novel context highlights the influence of culture on EI.

Design/methodology/approach

The critical incident technique (CIT) was adopted as the qualitative methodological approach using a self-administered form and semi-structured interviews to collect empirical data from a sample of 34 Vietnamese hotel workers in 19 different hotels.

Findings

The findings show that following Joseph and Newman’s (2010) cascading model of EI would help hotel workers in their practice. The research also found different factors hindering the EI practice from the individual and organisational levels. Vietnamese culture was believed to guide deep-acting and meditation. Language barrier and manager support emerged as significant factors that could help or hinder their EI practice.

Research limitations/implications

The research proposes a conceptual framework addressing the factors that could help or hinder the EI practice and provides implications for HR practices and management. Caution could be taken when applying the research implications because of the small sample as a nature of qualitative research.

Originality/value

To the best of the authors’ knowledge, this is the first attempt to appraise the EI practice adopting the CIT as a qualitative methodological approach in an under-research context and add evidence to the theoretical links between EI, EL and ER.

Abstract

Purpose

The purpose of this study is to investigate the resistance in management accounting practices (MAPs) in a developing economy in the manufacturing and service sectors in Vietnam.

Design/methodology/approach

Data collection was carried out using survey questionnaires in Vietnamese language. The questionnaires were distributed to selected respondents from the manufacturing and service organisations in Vietnam. Textual structuralism was used to analyse different categories of data, i.e. survey questionnaires, photos and qualitative texts obtained from the literature.

Findings

The findings indicate that the usage of MAPs is more prevalent in the manufacturing sector than in the service sector. In addition, various traditional and contemporary MAPs are being used concurrently in Vietnam, which challenges the classical twofold dichotomy between mere socialism and mere neoliberalism.

Research limitations/implications

The textual and photographic structuralism is used in this study to analyse primary data (geography and society and time) in a static setting. Hence, it does not analyse the research phenomena in a dynamic equilibrium setting to view the development of the research phenomena over time. Further research could expand data collection to include longitudinal and dynamic settings.

Practical implications

MAPs can be implemented in economic systems ranging from command to capitalist systems. Although most countries in the world follow a mixed economic system, specific MAPs could be designed for a transitional economic system such as that of Vietnam. This affects both theorists and practitioners in Vietnam applying sustainable MAPs to boost a country's competitiveness during transition.

Originality/value

This study expands understanding of the conformity of MAPs in relation to economic systems under the Communist Party of Vietnam (CPV) – the ruling party of the Socialist Republic of Vietnam. Understanding the differences in the way these MAPs are utilised constitutes an essential area of the accounting discipline to advance MAPs in Vietnamese enterprises and progress theoretical development of sustainable MAPs.
