This study aims to investigate whether the extent of corporate disclosure, proxied by COVID-19-related disclosure, affects the dividend policy of listed firms.

The study uses a multinomial logistic regression model to examine the relation between corporate disclosure and the dividend policy of the 100 largest market-cap firms in Vietnam in 2021. The COVID-19 pandemic, with its unique impact on business operations, serves as the backdrop for this analysis.

The findings indicate that firms with more extensive COVID-19-related disclosure are more inclined to distribute dividends in the form of stocks or cash instead of omitting them.

This research contributes to the understanding of how corporate disclosure practices influence a firm’s financial decisions, particularly in the context of the COVID-19 pandemic. The findings hold implications for corporate financial decision-making during times of macroeconomic shock.

This paper aims to measure the COVID-19-related disclosure extent of listed firms in Vietnam and its associated factors.

The authors apply a previously developed reporting framework to evaluate the disclosures of 100 listed firms with the largest market capitalization on the Hanoi and Ho Chi Minh stock exchanges as of 31 December 2021. The disclosures were from integrated reports, annual reports, corporate governance reports and financial statements. The authors then used a regression model to examine the factors that influenced the disclosures, such as corporate governance, ownership concentration and firm profiles.

The research results reveal that the extent of COVID-19-related disclosure in Vietnam is relatively low. It also finds that the audit committee, firm size, age and industry are positively associated with the extent of COVID-19-related disclosure.

To the best of the authors’ knowledge, this study is the first to examine COVID-19-related disclosures of listed companies in Vietnam and their determinants. It contributes significantly to the empirical evidence in this field. The findings of this study can help corporate managers and policymakers to improve information disclosure practices during future financial crises.

The health and environmental hazards associated with synthetic dyes have led to a revival of natural dyes that are non-toxic, environmentally benign and coupled with various functions. The study aims to investigate and develop the potentiality of a popular herb called Chromolaena odorata (C. odorata) as a sustainable and stable dyestuff in textiles.

Natural colorant extracted from C. odorata leaves is used to dye the worsted fabric, which is one of the premier end-use of wool in fashion, via the padding method associated with pre-, simultaneous and post-mordanting with chitosan, tannic acid and copper sulfate pentahydrate. The effects of extraction, dyeing and mordanting processes on fabric’s color strength K/S and color difference ΔE_CMC are investigated via International Commission on Illumination’s L*a*b* color space, Fourier transform infrared spectroscopy, scanning electron microscope, color fastness to washing, rubbing, perspiration and light.

The results obtained indicate extraction with ethanol 90% with a solid/liquid ratio of 1:5 within 1 h, and coloration with a liquor ratio of 1:5 (pH 5) within 2 h under padding pressure of 0.3 MPa are the most effective for coloring worsted fabric.

The C. odorata’s application as a highly effective dyestuff possessing good colorimetric effectiveness has expanded this herb's economic potential, contributing partly to economic growth and adding value to wool in global supply chain.

C. odorata dyestuff has prevailed over other natural colorants because of its impressive color fastness against washing, rubbing, perspiration and especially color stability for pH change.

This paper aims to explore how research and development (R&D) scientists and engineers can contribute to sustainability initiatives in their organisations.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

This paper aims to explore how family culture can contribute to support the development of corporate social responsibility (CSR) initiatives in a Korean immigrant enterprise in Vietnam.

This research highlighted a critical case, in which entrepreneurs and most of the organisational members share a common family culture and the culture support management capability of an entrepreneur, during the introduction of a new organisation initiative. In addition, Bourdieu’s tripartite analytical framework of field, capitals and habitus was adopted to facilitate the case analysis.

Firstly, the motivation behind the development of CSR came from the intention to gain access to the local capital market. Secondly, family culture plays an important role in maintaining the support of organisational actors to support the decision of the entrepreneur.

This research contributes to the emerging literature about CSR and immigrant entrepreneurship. This study sheds light on how family culture can aid the leadership of CSR initiatives and CSR practices in the context of the immigrant organisation.

This study identifies processes that immigrant entrepreneurs can use to inspire organisational members to engage in a new initiative in which organisational culture and norms can help to overcome challenges to enable engagement with a novel initiative.

This paper explains how family culture supports the leading role of an entrepreneur, in which the absolute pressures inherited from family values and traditions in the place of origin help an organisation to overcome existing barriers such as lack of time and financial support towards a new initiative.

This study addresses the empirical results of the spillover effect with export as the primary economic activity that enhances local businesses' total factor productivity (TFP). A learning mechanism is expected to be generated and used as the basis for the policy implication.

This study adopted the Cobb–Douglas function and multiple estimation approaches, including the generalized method of moments, the Olley–Pakes and the Levinsohn–Petrin estimation techniques. The findings were estimated based on the panel data of a Vietnamese local businesses survey conducted by the General Statistics Office of Vietnam (GSO) from 2010 to 2019.

The results showed that the highest TFP belongs to the businesses in the Southeast region, the Mekong Delta region, the mining industry and the foreign-invested enterprises. The lowest impacted TFP are businesses in the Northwest region and agricultural, forestry and fishery sectors. In addition, the estimated results also show that the positive spillover effect on TFP is shown through forward and backward linkage. The negative spillover effect is expressed through the backward and horizontal channels.

This study offers original empirical evidence on the learning mechanisms via which exports contribute to productivity improvement in a developing Asian economy, so making a valuable contribution to the existing academic literature in this domain. The findings of this research make a valuable contribution to the advancement of understanding on the many ways via which spillover effects manifest such as horizontal, forward, backward and supplied-backward linkage.

The study's findings indicate that it is advisable for governments to give priority to the development and improvement of forward and supply chain linkages between exporters and local suppliers. This approach is recommended in order to optimize the advantages derived from export spillovers. At the organizational level, it is imperative for enterprises to strengthen their technological and managerial skills in order to efficiently incorporate knowledge spillovers that originate from overseas partners and trade counterparts.

This study sheds new evidence on the export spillover effect on productivity in emerging economies, with Vietnam as the case study. The paper contributes to the research's originality by adopting novel methodological aspects to estimate local businesses' impact on total factor productivity.

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.

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.

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.

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.

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.

This paper aims to explore green technology (GT) transfer through the perceptions of both business managers and technology specialists, who have been identified as the foremost practitioners of this practice.

A total of 22 semi-structured interviews were conducted with business leaders and technology scientists. The interviewees were asked to share their views on the motivations for importing GT; their familiarity with, knowledge of and understanding of GT transfer and the current GT performance in their organization; the key strengths of GT transfer and its limitations; the barriers to the use of GT; and their usefulness. The theoretical framework of actors’ resistance to institutional demands of Oliver (1991) is used as a theoretical lens to investigate the perceptions of the interviewees.

This study suggests that despite some benefits of the adoption of GT, such as increasing competitive advantage and improving green operations, there are huge concerns over the use and importation of GT. More specifically, almost all the technicians were concerned about the technical risks resulting from the lack of operational tests, the old technologies and the lack of knowledge transfer. Meanwhile, the paucity of specific regulations, guidance and environmental standards has been reported by business managers as one of the primary constraints for this movement.

This research contributes to the emerging literature on GT transfers in the developing world. It proves that the lack of communication and the scarcity of a true champion for GT efforts have reduced the efficiency of GT transfer.

By shedding light on the intricate nature of the relationships arising from GT adoption in organizations, this paper aims to support business leaders and standard setters in making a decision regarding the implementation and promotion of GT transfer, especially in the context of developing countries.

To the best of the authors’ knowledge, this is one of the first studies to explore eco-friendly technology transfers in a developing country from the micro-level perspective of both business and technology practitioners of GT-recipient organizations.
