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
This paper aims to present a new discrete method to predict average excess pore pressure and degree of consolidation for soft ground using prefabricated vertical drains under time-dependent surcharge and/or vacuum loading and multi-soil layers.
Design/methodology/approach
The drain is discretized into a number of mesh points at which the average excess pore pressure is estimated. The conventional Laplace technique is used to solve the analytical equations. The proposed method is validated with previous findings reported in the literature. Moreover, field measurements are used to verify the accuracy of the proposed method with a case history of ground improvement by prefabricated vertical drains using the vacuum consolidation technique.
Findings
In comparison to past studies, this new discrete method is simpler to be implemented in a spreadsheet calculation to achieve a rational solution with less computational time for similar consolidation problems. Moreover, the current approach also incorporates a solution for multi-soil layers, which can hardly be derived by analytical solutions.
Originality/value
According to authors’ knowledge, this is the first-time discrete method by Laplace transform technique is applied for the vertical drain.

Abstract
Purpose
The purpose of this paper is twofold: first, to investigate strategies that external stakeholders can employ to affect construction project outcomes and, second, to identify essential requirements for utilising each strategy.
Design/methodology/approach
A new theoretical framework of stakeholder influence strategies was proposed and applied. The research design is a multi-case study, comprising four cases in the construction industry in Vietnam.
Findings
Seven specific strategies were found, including inputs withholding, inputs compromising, communication, direct action, coalition building, conflict escalation and credibility building. When possessing project inputs, stakeholders can affect a project directly via a withholding or compromising strategy. Communication is available to those who have basic communicating skills; however, direct action is only employed by groups that include a large number of members. Objectors must have common interests or goals with their potential allies for using coalition building. Conflict escalation is restricted to communities having distinctive characteristics which can be used to create new problems sensibly, while credibility building is used by parties possessing adequate resources and expertise.
Research limitations/implications
This study’s generalisability may be limited by the main source of data and the types of projects in the selected cases.
Practical implications
This study provides directions for project managers to predict stakeholder influence by taking project inputs and utilisation requirements of the strategies into consideration.
Originality/value
This study is one of the first investigations on stakeholder-attributes-related requirements for utilising influence strategies in projects.

Abstract
Purpose
The purpose of this paper is to investigate how individual differences predict personal business ethics of business students with a particular focus on how these factors moderate the relationship between ethical organizational interventions and personal business ethics perception.
Design/methodology/approach
Totally, 488 participants completed Clark’s Personal Business Ethics Scores (PBES) survey. ANOVA analyses were then performed.
Findings
Significant correlations were observed between personal business ethics and diversity professional development, age, and education. The authors found significant difference on ethical behavior and diversity professional development. Professional development focusing on diversity was positively related to reports of ethical behavior for women but no significant relationship was observed for men. Furthermore, professional development focusing on ethics was positively related to reports of ethical behavior for younger employees but no significant relationship was observed for older employees.
Research limitations/implications
Researchers and scholars in cross-cultural management and business ethics fields can benefit from this study as it provides more empirical results in understanding the impact of demographic, educational, and cultural factors on the ethical maturity of business students in different countries.
Practical implications
Leaders, managers and practitioners, can benefit from this study as it provides managerial implications in managing this workforce in the most effective and efficient manner. The results from this research suggest that ethics education and diversity training play the critical role in creating an ethical climate on workplace.
Originality/value
This study fills the gap within the literature and offers a unique analysis of the personal business ethics of Russian business students. Determining the types of business ethics education and training that are the most effective in Russia would be beneficial to researchers and practitioners.

This study aims to explore the situations and socio-economic and health-related factors associated with employment of older men and women in Vietnam.
Abstract
Purpose
This study aims to explore the situations and socio-economic and health-related factors associated with employment of older men and women in Vietnam.
Design/methodology/approach
This study used the nationally representative data in 2019 with a sample size of 3,049 older persons (those aged 60 and over). This study applied logistic regression analyses.
Findings
This study found that there were significant differences in employment rates between various groups of older men and women in terms of age group, residential place, marital status and educational level. Controlling for age, education, marital status, place of residence and (in) sufficient income for daily living, the results from logistic models indicated that health issues were strongly associated with lower probability to be employed for both genders. In all tests and regression models, that age and health condition were consistently related with lower employment probability of older persons implied an important consideration in raising normal retirement ages for both men and women.
Research limitations/implications
Due to limitation of the cross-sectional data, this research could not explore how health influences older people’s employment overtime.
Practical implications
Findings of this research provide important and adaptive policy insights for Vietnam to take advantage of older workers for economic growth under an aging population.
Originality/value
To the best of the authors’ knowledge, this has been among the first studies exploring the role of health, which was presented by different indicators, determining employment of older men and women in Vietnam.

Abstract
Purpose
The purpose of this paper is to lay the necessary conceptual and empirical groundwork that advances knowledge about paternalistic leadership (PL). PL is reinterpreted as a leadership style consisting of authoritative, moral and benevolent leadership. The mediating role of trust is examined, and a formal, unified construct model of PL is suggested through evidence of construct validity.
Design/methodology/approach
An on-site survey was used to collect data from 312 full-time employees in nine organizations in China. Factor analysis, reliability and validity test, and an analysis of bivariate correlations were conducted.
Findings
The new construct of PL achieved a positive alignment and coherence among the three dimensions. Subordinates’ trust was found to be critical for paternalistic leaders to be perceived as effective leaders.
Research limitations/implications
Leadership and its effectiveness were examined only at the dyadic level. The levels of the supervisors and their effectiveness differ because some were from middle management, whereas others were from first line managers.
Practical implications
Trust is an important explanatory mechanism for the relationship between PL and employee performance, especially in China. It is a key factor that creates loyalty and builds a good relationship between leaders and subordinates.
Social implications
Trust signals a strong sense of sharing within the relationship. It induces positive emotional feelings in their leader by the subordinates and, therefore, taps into positive evaluations about the effectiveness of their leader.
Originality/value
This study developed the theoretical underpinnings and provided measurement instruments for PL. It offered a formal, unified construct model of PL.

Abstract
Purpose
Modernization and the rise of living standards have introduced new variants of traditional foods, from their tastes to the way they are enjoyed. This study aims to explore and examine the impacts of both traditional and modern marketing stimuli on restaurant choice intention for experiencing culinary traditions, hence answering the question of how traditional and modern aspects live together to bring about the most desirable experience for customers of traditional cuisine.
Design/methodology/approach
Based on the stimuli-organism-response (S-O-R) theory and mixed research methods, a model linking service quality dimensions, perceived value and restaurant choice intention is formulated and tested on quantitative data from 431 customers of Gen Y and Gen Z, given the case of Vietnamese Pho.
Findings
The findings show that food quality demonstrates the strongest impact on restaurant choice intention, followed by authenticity and nostalgia marketing. These relationships are partially mediated by perceived value. Hygiene risks and perceived value are also found to directly affect restaurant choice intention. Nevertheless, our findings are quite different between Gen Y and Gen Z customers.
Practical implications
This research provides crucial strategic implications for restaurant managers when it comes to serving traditional foods for different generations.
Originality/value
This study responds to the existing gap by examining and comparing the impacts of traditional and modern marketing stimuli on restaurant choice intention through the mediating role of perceived value. Our study also actively contributes to the ongoing multigenerational research stream by affirming the moderation role of generations (Gen Y and Gen Z) in those relationships.

Abstract
Purpose
This paper aims to present a hybrid review combining the theory, context, characteristics and methodology (TCCM) framework and bibliometric analysis of international business research from 1991 to 2023, shedding light on the field’s growth, trends and key contributors.
Design/methodology/approach
Relevant papers were selected using the preferred reporting items for systematic reviews and meta-analyses model. Initially, this paper conducted a descriptive analysis to identify prolific institutions, countries and journals. Using bibliometric techniques and the TCCM framework, this paper analyzed theory, context and method visualized through word clouds and keyword co-occurrence. The characteristic aspect was analyzed using bibliographic coupling to identify major themes, providing a comprehensive understanding of the most significant factors in international business research.
Findings
The analysis of a data set comprising 5,644 documents reveals a steady increase in the annual growth rate of publications, highlighting the growing significance of international business in the global economy. First, this paper noticed a significant increase in publications in leading international business journals, with the Journal of International Business Studies being the most prolific. Second, using the TCCM framework, this paper discovered that the resource-based view, institutional theory, transaction cost theory and internalization theory are predominant in international business research. Most studies have concentrated on firm or enterprise-level entities, followed by country-level analyses. This paper also identified six main themes: (1) innovation and strategy, (2) market, (3) HR impact and leadership, (4) marketing, (5) internationalization and (6) entrepreneurship. Quantitative methods have been the most frequently used research design, followed by qualitative and mixed methods.
Research limitations/implications
The study offers researchers and practitioners a roadmap for future investigations, collaboration and innovation in international business, thereby advancing the knowledge and understanding of this complex field within a globally interconnected economy.
Originality/value
This study provides insights into growth and trends, identifying journals, clustering research topics and enhancing theoretical and methodological understanding in the field of international business.

Abstract
Purpose
COVID-19 and its measures such as physical distancing have shifted consumer payment behaviors toward cashless payment. Physical distancing is likely to remain a norm for some time to come and will be relevant in any future pandemics. This study aims to examine the impact of consumers’ perceived value of cashless payment on their use intention in the physical distancing context, with the mediating role of psychological safety and the moderating role of trust propensity.
Design/methodology/approach
This study used a survey method to obtain data from 690 consumers in an Asian emerging market, i.e. Vietnam. The data were analyzed using different statistical methods, including structural equation modeling.
Findings
Results show that perceived value of cashless payment positively affects use intention, and this effect is mediated by psychological safety. Furthermore, trust propensity has a positive moderating effect on the link between perceived value and psychological safety.
Practical implications
This study’s findings provide implications for retailers and other stakeholders in implementing and promoting cashless payment systems, especially in the physical distancing context.
Originality/value
This study is among the first attempt to explain the relationships between consumers’ perceptions, feelings of psychological safety and use intention toward cashless payment in the physical distancing context. The study’s findings may also be relevant to any future pandemics.

Abstract
Managing complex construction projects is a challenging task because it involves multiple factors and decision-making processes. A systematic evaluation of these complex factors is imperative for achieving project success. As most of these factors are qualitative or intangible in nature, decision makers often rely on subjective judgements when comparing and evaluating them. The hybrid techniques that integrate fuzzy set theory and the analytic hierarchy process (AHP) are able to deal with such problems. This chapter discusses various hybrid techniques of the fuzzy AHP and presents an application of these techniques to the evaluation of transportation project complexity, which is essential for prioritising resource allocation and assessing project performance. Project complexity can be quantified and visualised effectively with the application of the fuzzy AHP. This chapter enhances the understanding of construction project complexity and fuzzy hybrid computing in construction engineering and management. Future research should address the calibration of fuzzy membership functions in pairwise comparisons for each individual decision maker and develop computational tools for solving optimisation problems in the constrained fuzzy AHP. In the area of construction project complexity, future research should investigate how scarce resources are allocated to better manage complex projects and how appropriate resource allocation improves their performance.
