This paper aims to explore factors influencing Vietnamese people’s susceptibility to fraud through cryptocurrency Ponzi schemes.

This study uses the gullibility theory, the theory of planned behavior theory, the traditional theory of finance and the theory of financial behavior, to develop a questionnaire which is then sent to respondents who are Vietnamese individuals. Subsequently, the partial least squares structural equation modeling approach (PLS-SEM) is used to analyze 370 collected responses.

This research shows the important roles that trust, risk appetite and knowledge of Ponzi play in respect of fraud susceptibility, among which trust has the highest positive impact. Moreover, there is no evidence of relationships between Vietnamese people’s susceptibility to fraud via cryptocurrency Ponzi schemes and attitudes toward investment scams, knowledge of investment or knowledge of Ponzi schemes.

This paper collects only 370 valid responses, which raises some questions regarding the diversity and representativeness of the survey sample.

This study provides evidence on factors affecting Vietnamese people’s fraud susceptibility to cryptocurrency Ponzi schemes, which helps both authorities and individuals to be vigilant against investment scams.

This research proposes several recommendations to prevent investment scams in cryptocurrency trading, from the perspective of state regulators and individuals.

This working paper provides a new approach using PLS-SEM to build a theoretical framework for the possibility of becoming victims of investment scams in Vietnam using a combination of different theories from criminology and finance.

Due to the vital role of innovation for firms to respond to the change and achieve competitive advantage, the purpose of this study is to investigate the influence of knowledge-oriented leadership (KOL) on innovation performance via the mediating role of knowledge sharing (KS). This study also explores the moderating role of organizational justice in the relationship between KS and innovation performance.

Analysis of moment structures and structural equation modeling are applied to examine the relationship among the latent factors in the proposed research model using data collected from 335 participants in 121 manufacturing and service firms in Vietnam.

The findings revealed that KOL serves as a key precursor to foster innovation performance directly or indirectly through active and passive KS behaviors. In addition, the paper highlights the moderating role of organizational justice in strengthening the impact of KS activities on innovation performance.

By highlighting the important role of KOL for stimulating KS behaviors, this paper provides a valuable understanding and novel approach for firms to improve innovation performance. The research findings support the idea that building a climate of justice is crucial to enhance the effects of KS on innovation performance.

This study contributes to bridging the research gaps in the literature and advances the insights of how KOL directly and indirectly stimulates innovation performance via mediating roles of active and passive KS processes under the climate of justice.

Drawing on social exchange theory, this paper aims to clarify the influences of ethical leadership (EL) on knowledge-sharing (KS) behaviours of employees through the mediating roles of affective- and cognitive-based trust in leadership. This work further offers deeper insight into the moderating mechanism of distributive justice in the EL–KS relationship.

Structural equation modelling (SEM) is used to investigate the influential degree of EL, aspects of employee trust in leadership and distributive justice on employee behaviours towards tacit and explicit knowledge via data collected from 339 participants in 75 Vietnamese firms.

The empirical findings reveal that employee trust in leadership positively mediates the relationship between EL and KS behaviours. In particular, distributive justice significantly fosters the impacts of EL on tacit and explicit KS behaviours.

Managers and practitioners should strengthen EL practices to build and maintain employee trust in them for promoting KS behaviours. In addition, research highlights the necessity of establishing distributive justice in organisations to enhance the effect of EL on KS behaviours of employees.

This paper is unique in its attempts to advance the insights on the theory of leadership and knowledge management by investigating the different moderated-mediation mechanisms in the relationship between EL and specific aspects of KS behaviours.

This study aims to investigate the influence of human resource management (HRM) practices on two aspects of innovation capability namely product and process innovation. It also attempts to clarify the HRM-innovation relationship by examining the mediating roles of specific components of knowledge management capability (KMC) namely knowledge acquisition, knowledge sharing and knowledge application.

This research used the quantitative method and structural equation modeling (SEM) approach to examine hypotheses with data obtained by survey from 325 participants in 98 Vietnamese firms.

The empirical findings show the evidence on the mediating roles of components of KMC in the HRM-innovation relationship and indicate that HRM practices have a greater impact on product innovation compared to its effects on process innovation. In contrast, all three components of the KMC produce larger impacts on process innovation than on product innovation. In particular, it highlights the key role of knowledge sharing in predicting product and process innovation in comparison to the roles of knowledge acquisition and knowledge application.

CEOs/managers should practice and manage their human resource to foster organizational capability for product and process innovation directly or indirectly via enhancing aspects of KMC namely knowledge acquisition, sharing and application.

By investigating the mediating mechanisms of specific components of KMC, the paper has significantly contributed to advancing the body of knowledge of innovation theory and providing deeper insights on the correlation between HRM practices and aspects of innovation capability namely product and process innovation.

This study aims to investigate specific professional competencies of teachers to implement education for sustainable development (ESD) in the contexts of Vietnam.

The authors carried out a Delphi study with eight ESD experts in Vietnam to collect their expertise viewpoints regarding teachers’ ESD professional competencies.

In total, 13 competencies related to three dimensions (content knowledge/cognitive, pedagogical and pedagogical content knowledge, motivation and volition) were highlighted by ESD experts.

The proposed teachers’ competencies were based on the ideas of a small group of experts, and the results need to be tested, refined and confirmed by further work. Besides, in this study, we have not defined the levels of achievement for each competency as well as developed assessment tools.

The specific professional competencies for teachers can be considered as a foundation for developing educational offers focusing on promoting the specific teachers’ professional competencies in basic ESD training.

Studies on educators’ professional competencies for ESD mostly were conducted in western countries. However, competencies do not exist independently; instead, they should be considered in specific contexts of teaching, school, culture and society. This research is among one of the first studies that contextualizes teachers’ competencies in a non-western context.

The aim of this study is to investigate how corporate social responsibility (CSR) contributes to organizational citizenship behavior for the environment (OCBE) among employees in hotel industry. Corporate green brand should be built not only from the provision of green products or services but also from green behavior among employees in their daily activities. This study also seeks the understanding of the moderating effects of corporate entrepreneurship (CE) and employees’ attachment styles on the relationship between CSR and OCBE.

The data for testing the study model were harvested from respondents in the hotel industry in Vietnam business context.

The research results unveiled the positive effect of CSR on OCBE and the roles of CE and employee attachment styles in moderating this effect.

Hospitality organizations should integrate CSR initiatives into their sustainable strategy to shape employee OCBE. Entrepreneurial values should also be cultivated among employees to drive them to further respond to CSR initiatives and engage in OCBE.

This study expands CSR and green research streams by identifying the effect of CSR on OCBE among hotel employees as well as moderation mechanisms of CE and employee attachment styles for such an effect.

This paper aims to investigate shrimp income losses of farmers in the four farming systems in the research areas of Ca Mau, Vietnam, and determine the vulnerability of shrimp farming income to climate change events.

Field research interviews were conducted with 100 randomly selected households across the four farming systems to access shrimp income status and vulnerability levels to climate change events. Four focus groups, each aligned to a particular farming system, were surveyed to categorise likelihood and consequences of climate change effects based on a risk matrix worksheet to derive levels of risk, adaptive capacity and vulnerability levels.

Shrimp farmers in the study areas have been facing shrimp income reduction recently and shrimp farming income is vulnerable to climate change events. There are some differences between farmers’ perspectives on vulnerability levels, but some linkages are evident among shrimp farmer characteristics, ramifications for each farming system, shrimp income losses and shrimp farmers’ perspectives on vulnerability levels of shrimp incomes. From an income perspective, farmers operating in intensive shrimp farming systems appear to be less vulnerable to existing and expected climate change effects relative to those in mixed production or lower density systems.

Having identified the vulnerability level of shrimp farming income to climate change events in different farming systems based on shrimp farmers’ perspectives, the paper adds new knowledge to existing research on vulnerability of the aquaculture sector to climate change. The research findings have implications for policymakers who may choose to encourage intensive shrimp farming to enhance shrimp farmer resilience to the effects of climate change as well as improving cultivation techniques for shrimp farmers. The findings could thus guide local government decision-making on climate change responses and residents of Ca Mau as well as within the wider Mekong Delta in developing suitable practical adaption measures.
