Abstract
Purpose
The purpose of this paper is to propose an approach, which is easy to implement, for estimating the thickness of the air layer that may separate metallic parts in some aeronautical assemblies, by using the eddy current method.
Design/methodology/approach
Based on an experimental study of the coupling of a magnetic cup core coil sensor with a metallic layered structure (consisting of first metal layer/air layer/second metal layer), which is confirmed by finite element modelling simulations, an inversion technique relying on a polynomial forward model of the coupling is proposed to estimate the air layer thickness. The least squares and the nonnegative least squares algorithms are applied and analysed to obtain the estimation results.
Findings
The choice of an appropriate inversion technique to optimize the estimation results is dependent on the signal-to-noise ratio of measured data. The obtained estimation error is smaller than a few percent, for both simulated and experimental data. The proposed approach can be used to estimate both the air layer thickness and the second metal layer thickness simultaneously/separately.
Originality/value
This model-based approach is easy to implement and available to all types of eddy current sensors.

Abstract
Purpose
This study aims to evaluate the impact of climate change on some specific areas of agricultural production in Quang Nam Province, including assessing the possibility of losing agricultural land owing to sea level rise; assessing the impact on rice productivity; and, assessing the impact on crop water demand.
Design/methodology/approach
This study used the method of collecting and processing statistics data; method of analysis, comparison and evaluation; method of geographic information system; method of using mathematical model; and method of professional solution, to assess the impacts of climate change.
Findings
Evaluation results in Quang Nam Province show that, by the end of the 21st century, winter–spring rice productivity may decrease by 33%, while summer–autumn rice productivity may decrease by 49%. Under representative concentration pathway (RCP) 4.5 scenario, water demand increases by 31.1% compared to the baseline period, of which the winter–spring crop increases by 28.4%, and the summer–autumn crop increased by 34.3%. Under RCP 8.5 scenario, water demand increases by 54.1% compared to the baseline period, of which the winter–spring crop increases by 46.7%, and the summer–autumn crop increased by 63.1%. The area of agricultural land likely to be inundated by sea level rise at 50 cm is 418.32 ha, and at 80 cm, it is 637.07 ha.
Originality/value
To propose adaptation solution to avoid the impacts of climate change on agriculture, it is necessary to consider about the impact on losing land for agriculture, the impact on rice productivity, assess the impact on crop water demand and other. The result of this assessment is useful for policymakers for forming the agriculture development plan.

Abstract
Purpose
This paper aims to explore how research and development (R&D) scientists and engineers can contribute to sustainability initiatives in their organisations.
Design/methodology/approach
This paper uses a critical case study methodology, focussed on a large Vietnamese company in which business leaders sought to engage R&D scientists and engineers in sustainability initiatives focussed on eco-innovation and eco-efficiency. Bourdieu’s theoretical lens of habitus, capitals and field facilitates a relational analysis of the findings.
Findings
While R&D scientists and engineers adapted well to early changes aligned with eco-innovation, they struggled to engage with sustainability initiatives in the case firm. This study explains adaptions and constraints as scientists and engineers’ professional habitus and capitals, and their broader organisational field.
Practical implications
This paper provides insight into how organisations might integrate professional acculturation and appropriate facilitators to promote the additional contribution of scientists and engineers to sustainability initiatives in the context of an organisation.
Social implications
Although eco-innovation and eco-efficiency are only potential dimensions of comprehensive organisational sustainability reform, this research provides insight into how engaging scientists and engineers with a broader social sustainability agenda might be advanced.
Originality/value
The study addresses calls for empirical insights into ways that scientists and engineers can commit to organisational sustainability practices based on the configurations of habitus, capital and organisational field.

Abstract
Purpose
The role of customers has moved from reactive to proactive, and they require more control over digital touchpoints. The quest for authenticity is their response to the dark side of interactive marketing – forms of faking, manipulation and exploitation. Authenticity becomes a key topic in interactive marketing as it reflects how customers assess digital touchpoints. However, there is a lack of comprehensive knowledge of authenticity in the interactive environment.
Design/methodology/approach
This article consolidates the authenticity studies in various digital touchpoints using the entity-referent correspondence framework. This research employs bibliometric analysis and thematic analysis of 103 articles in the last 15 years.
Findings
Five research clusters are identified: (1) human, (2) brand-generated content, (3) user-generated content, (4) branded platforms and (5) new technologies-based touchpoints (artificial intelligence, augmented reality and virtual reality). Most interactive marketing studies focus on human and content authenticity, and new technologies-based touchpoints lack comprehensive conceptualization. The review synthesizes the types of authenticity used in each touchpoint and highlights the importance of true-to-creator-self and true-to-customer-self in customer evaluation. We further propose a research framework with four antecedent groups and outcomes.
Practical implications
Our research supports managers by highlighting the type of authenticity prioritized in each touchpoint's development.
Originality/value
To answer the call from interactive marketing researchers, this research highlights the distinct definitions of authenticity at various digital touchpoints rather than looking at the overall brand. Trends, gaps and future research agenda of the authenticity concept in technology adoption and customer behavior are discussed.

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
Subject area
Decision-making seems simple, but, in reality, it is not an easy task to decide the cause for its profound result or consequence, leading to inevitable failures. Therefore, a leader must recognize whether there is something incorrect so as to avoid bad results. A good leader is a person who carefully reviews and analyzes aspects of a problem, knows the strengths and weaknesses of his organization and evaluates what the advantages or risks are. It cannot be denied that the appropriate options will reap many benefits to the business. For such important things, this paper will discuss the dilemma of Viettire, a tire distributor company in Vietnam. Accordingly, its CEO was worried about what strategic option he should adopt to approach the Myanmar market while ensuring a strategic fit to its company’s resources and capabilities and also to the overall market demands of the tire industry environment in both countries. However, with different ideas, the expansion strategies in this new market become controversial. The General Director and Founder of Viettire were wondering how Viettire could expand its existing business into Myanmar. To expand the company to new emerging market in Myanmar, Hoang Nguyen – CEO of Viettire – had conducted a strategic analysis of external environment factors to define the opportunities and threats when doing business in Myanmar by using Porter’s five forces model, S.W.O.T and competitive advantages analysis. The results indicated that Myanmar’s business environment is highly risky for foreign investors because of uncertain political, economic, social reforms in the process. Among three options, namely, exporting, licensing and wholly owned, however, Option 2 is illustrated as the best strategy for its dilemma.

Case overview
As for a market mechanism, what produces, how and for whom, is not the business’s demand but the consumer’s demand. The business sells only what the market needs, not what it has. In the period of increasingly competitive conditions, stabilizing and expanding markets are a prerequisite for survival. If stability is seen as a “defensive” way, expansion is a “defensive attack” like trying to hold on the “pie” that the market gives to itself. This strategic action is to strengthen regular, close relationships with existing customers and establish new customers. As a result, the potential market is transformed into a target market. Hence, decision-making of which market, which method is the issue that a leader has to think the choice to avoid risks. Mr Hung, Viettire’s co-owner, suggests that Myanmar should be taken into account as a company’s new entry, thus exploring this potential market to increase the company’s growth and profitability. In the progress, Viettire’s marketing team had been doing a thorough tire market investigation in Myanmar. It was concluded that this emerging country, especially Yangon City, was the most suitable for those who were willing to embark on an overseas investment expansion. They believe this was a good opportunity to gain market share compared with other entrants and competitive rivals; if Viettire hesitated to invest, others definitely had jumped in with a first-mover advantage. However, the CEO, Mr Hoang, was worried about what strategic option he should adopt to approach this new market while ensuring a strategic fit to its company’s resources and capabilities and also to the overall market demands of the tire industry environment in both countries.
Expected learning outcomes
Understand the basic decisions that firms contemplating foreign expansion must make: which markets to enter, when to enter those markets and at what scale. Recognize the current strategic decisions an organization is facing: positioning, portfolio and market expansion approach. Learn how to develop an effective strategic plan. Be familiar with different strategies for competing globally and their pros and cons. Evaluate various strategic options and decisions in accordance with a company’s resources and capabilities.

This study explores the effects of gender and participation in agricultural cooperatives on biodiversity conservation farming practices in vegetable production.
Abstract
Purpose
This study explores the effects of gender and participation in agricultural cooperatives on biodiversity conservation farming practices in vegetable production.
Design/methodology/approach
This study used data collected from a survey of 627 vegetable farmers in Viet Nam and employed the Ordered Probit regression model to examine the effects of gender and participation in agricultural cooperatives on biodiversity conservation farming practices.
Findings
We find that female vegetable farmers are more likely to conduct biodiversity conservation farming practices than male farmers. This gender difference is, however, removed when participation in agricultural cooperatives is controlled, suggesting that agricultural cooperatives effectively facilitate biodiversity conservation farming practices.
Research limitations/implications
It is noted that our study is not free from some limitations. First, we conducted our study on vegetable farmers only. The biodiversity conservation practices in vegetable cultivation might be different from other types of farming. Future studies should be conducted with other types of agricultural cultivation. Second, we do not have enough data to explain why female farmers are more likely to adopt biodiversity conservation practices than male farmers. Future studies should capture biological and social aspects of gender differences to address this limitation.
Originality/value
This study contributes to the literature on biodiversity conservation by presenting empirical evidence on the effects of gender and agricultural cooperatives. Participation in agricultural cooperatives is revealed to facilitate the adoption of biodiversity conservation practices. In addition, we find that the education of farmers, the number of years that farmers have been living in the local area and the quality of land and water are positively related to the adoption of biodiversity conservation practices in vegetable production.

Abstract
Purpose
The purpose of this paper is to investigate how emotional experience factors affect the obligation-related commitment. The emotional experience factors consist of positive factor, job satisfaction and negative factor, and emotional exhaustion from the study of Wong and Tay (2010); both facets have been studied with affective commitment but yet lack of study about normative commitment. Affective and normative commitments are both components of organizational commitment; while affective commitment refers to the intention of keeping the position because of the desire but not by any other attachment, whereas normative commitment is defined as staying for the reasons related to obligation. Also, by applying withdrawal construct of validation of job-hopping behavior, a connection was constructed between normative commitment and the two separated motives of job-hopping behavior, advance motive and escape motive (Lake et al., 2017).
Design/methodology/approach
To achieve such objectives, quantitative research is implicated using the primary data collected from online and offline surveys from employees who are currently working in many information technology (IT)-related companies in Ho Chi Minh City. As for analyzing tactic and method, SmartPLS software is applied to ensure the reliability and validity of the factors as well as confirming the significant and developing the hypotheses from the proposed construct.
Findings
The findings reveal the significant affect from workplace escape motive that leads to the behavior of job hop, but not from the career enhancement. The result also revealed the effect of indebted obligation when most of the employees maintain the low level of normative commitment and the proper increase in emotional exhaustion and job satisfaction can help to improve the normative commitment of such employees.
Originality/value
This study makes its contribution and recommendations to human resource management in IT industry.

Abstract
Purpose
This study aims to investigate the effects of entrepreneurial leadership on service innovation in the hospitality industry and examine the mediating effects of market-sensing capability and knowledge acquisition. Additionally, the study explores the moderating role of competitive intensity in the relationships between market-sensing capability, knowledge acquisition and service innovation, drawing on the dynamic capability theory and resource dependence theory.
Design/methodology/approach
The data for this study were obtained from 322 employees and 137 leaders working in 103 hotels in Vietnam, using a time-lagged approach. The collected data were analyzed using structural equation modeling in SPSS Amos 28.
Findings
The results of this study reveal a significant positive association between entrepreneurial leadership and service innovation, with mediation effects observed through both knowledge acquisition and market-sensing capability. Moreover, the findings demonstrate that competitive intensity moderates the association between knowledge acquisition and service innovation.
Practical implications
The results of this study provide implications for hospitality firms to cultivate entrepreneurial leadership through leadership training and development programs and enhance their dynamic capabilities (i.e. market-sensing capability and knowledge acquisition) to allow them to survive and develop in a competitive market.
Originality/value
This study advances entrepreneurial leadership research in the hospitality context by identifying mediating and moderating mechanisms that translate entrepreneurial leadership into hospitality firms’ service innovation.

Abstract
Purpose
Travel destinations worldwide are seeking smart ways to reduce the negative impact of tourism, and the public bike rental service (PBRS) is one of them. To investigate the usage intention of this service among visitors, the author of this research employs an integrated approach consisting of two psychological frameworks: the Norm Activation Model (NAM) and the Technology Acceptance Model (TAM).
Design/methodology/approach
The integrated NAM-TAM model is implemented to conduct a survey (sample n = 777) with visitors to Hanoi, Danang, and Ho Chi Minh City regarding the factors underlying their intentions to continue using the PBRS TNGo.
Findings
Structural equation models suggested that: (1) the NAM-TAM can explain behavioural intention to use a smart PBRS. Perceived Usefulness (PU), Perceived Ease of Use (PE), and Awareness of Consequences (AC) have positive and significant impacts on Attitude Towards Using (AT) and, thus, on Behavioural Intention to Use (BI). Also, Personal Norms (PN) positively influence BI. (2) Among the four independent variables, tourists' AC produces the most potent effect on the intention to continue using a PBRS.
Research limitations/implications
This study can start a new research direction of combining the NAM with other theoretical frameworks to explain customer behaviour in the field of sustainable tourism practices. Future research should explore the proposed model based on comparisons of different tourists’ backgrounds, including nationality, length of stay, spending level, visiting purpose, etc.
Practical implications
This research provides strategic implications for destination management organisations in boosting the use of PBRS amongst tourists, contributing to the environmental sustainability targets of the tourism industry.
Originality/value
This study responds to the existing gap by examining both functional value (indicated by PU and PE) and perceived environmental/social value (proxied by AC) in forming tourists’ attitudes towards PBRS and their usage intention. Our study, therefore, actively contributes to the research stream of tourist behaviour in the field of sustainable tourism practices from the altruistic behavioural perspective.
