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 investigate the effect of spray drying temperature and maltodextrin addition on the contents of phenolics, flavonoids, anthocyanins and antioxidant activities (2,2-diphenyl-1-picrylhydrazyl [DPPH] radical scavenging activity, ferric reducing antioxidant power and reducing power) of karonda powder.

Over the past few decades, the demands for application of natural colorants in food production have been attracting the attention of academic research and food industry. Anthocyanins, a red pigment commonly found on plants, show high potentials in the preparation of spray-dried pigment powder. This study, therefore, was conducted using full factorial design with two factors, namely, inlet temperature (150°C and 160°C) and soluble solid concentration (10, 15 and 20°Brix) with maltodextrin as carrier to produce pigment powder from karonda, an anthocyanin-rich fruit which is native to southeast Asia.

Increasing soluble solid content from 10 to 15°Brix resulted in a 42%–57% reduction in phenolic, flavonoid and anthocyanin contents. However, when increasing the amount of maltodextrin from 15 to 20°Brix, a lower reduction (approximately 11%–19%) was observed. In samples with the same °Brix, there was no significant variation in antioxidant contents and activities, especially at high maltodextrin ratios. In addition, the reducing power of samples dried at higher temperature (160°C) was higher than that of samples dried at lower temperature. Karonda spray-dried powder showed a good positive correlation (p < 0.01) between antioxidant contents and DPPH• activity.

To the best of the authors’ knowledge, in this study, for the first time, the effect of spray drying conditions on the quality of karonda powder was investigated.

This paper aims to explore how entrepreneurial culture (EC) and psychological empowerment (PE) support innovative work behaviour (IWB) of employees in organizations. First, it examines the impact of EC on IWB. It also explores the mediating effect of PE to support the EC – IWB relationship. Accordingly, it suggests a mechanism model to explain the relationship between EC and IWB.

This is an empirical research using quantitative methods. Data were collected via both face-to-face and online surveys from 308 employees in Vietnamese enterprises. The partial least squares-based structural equation modelling (PLS-SEM) approach was applied to test hypotheses in the research model.

Significant R-square values were achieved for both EC – PE and PE – IWB relationships, according to the PLS-SEM. The most interesting finding is the full mediating role of PE in the relationship between EC and IWB. Despite the non-significance in the direct impact of EC on IWB, the role of EC in promoting IWB is important in an indirect way through PE. The significant role of PE in facilitating IWB has been proven.

This research is one of the initial attempts to empirically build the roadmap from EC, as a typical type of organizational culture, through the mediating effect of PE to improve IWB. This roadmap provides top managers with a hierarchical view that effectively cascading interventions from the organizational level, such as EC, through a significant mediator as PE at the group level, and then down to IWB as a result at the individual level.

Given the severe impact of coronavirus disease 2019 (COVID-19) on bank business activities, this study aims to examine how green brand image and online trust affect customers' continuance intention (CI) under the boundary condition of perceived effectiveness of e-services (PEES).

An extensive review of the green marketing perspective was conducted to identify the incremental contributions of the current study (e.g. extensions of online trust and PEES). The authors used the common questionnaire survey strategy for the data collection while applying the partial least squares technique for further analyses.

Using data from 460 bank customers, the findings indicated that online trust positively mediates the relationship between green brand image and CI under the moderating effect of PEES. At high levels of PEES, online trust exerts strongest effect on customers' CI.

This study responds to the emerging call for understanding the PEES role, under which online trust leads to CI in the context of the global pandemic.

The authors provide bank managers with a helpful extension of green marketing with PEES to manage online trust and customer intention, thereby increasing the managers' strategic effectiveness.

The current study explores the moderating role of PEES that plays in the green brand image, online trust and CI relationships, in responding to the pandemic situation.

This study aims to develop a comprehensive understanding about employer branding dimensions as well as the dimension's possible links with turnover intentions through the lens of existing hospitality employees.

A survey was conducted based on a sample of 200 hospitality employees in order to examine relationships between employer branding dimensions and turnover intentions. Structural equation modeling (SEM) was used for data analysis and hypothesis testing.

The findings found that economic, social, development and security values had negative impacts on turnover intentions; however, the impact of application and interest values on turnover intentions were not confirmed.

Hospitality managers can prioritize actions and strategies that influence their staff's intentions to quit, subsequently reducing employee turnover.

Given the lack of studies on employer branding dimensions from the perspective of current employees, especially the employees’ relationships with employee turnover intentions, this study points out employer branding factors that impact employee turnover intentions in the settings of coronavirus disease 2019 (COVID-19). The findings add to the literature on employer branding and employee turnover management and provide insights for hospitality managers in the context of the New Normal.

A carbon tax has been widely discussed and implemented in developed countries to mitigate carbon emissions, but this measure is still quite new in developing countries. Recently, the ambition of Vietnam's government in mitigating emissions has been mentioned in international commitments. To achieve these targets, the government is making efforts to seek and implement mitigation measures in the country. While carbon pricing was introduced in Vietnam, there is no study simulating the effects of a carbon tax in the country. This study simulates the environmental and economic effects of a carbon tax and then proposes appropriate policies in Vietnam.

This study investigates the impact on the Vietnamese economy within the static computable general equilibrium (CGE) framework. Compared with previous models, the proposed model in this paper is a fairly standard CGE approach that tries to picture the economic system of Vietnam. In addition, a carbon tax on output will be modeled in this framework. This carbon tax mechanism is more flexible and direct when a carbon tax is based on direct emissions by industry level and the industry's carbon intensity. The paper decomposes the Vietnamese economy into 18 different production sectors, based on the different emission levels of CO₂. The CGE model makes possible to examine the impact of a carbon tax on the whole economy through all possible channels and to differentiate a separate carbon tax among different production sectors. The impact of a differentiated carbon tax is explored not only at the macroeconomic level but also at each different industrial level. Another feature of this paper is to investigate the impact of reallocation revenue from the carbon tax.

This paper has found that by designing carbon tax scenarios at different carbon prices ($1/tCO2, $5/tCO2, $10/tCO2) with different targeted industries, this study shows that higher carbon prices cause greater damage to GDP and welfare, but also better reductions in emissions. In addition, a carbon tax on the energy sectors results in milder economic and welfare damage but less emission reduction than when levying on all sectors. At the sectoral level, a carbon tax might cause sectoral restruction. Interestingly, the electricity sector is the most affected and also is the main contributor to reducing emissions in Vietnam. Finally, the study also shows that reallocation policies of new revenue from the carbon tax would reduce the economic damage caused by carbon taxes, and in many cases promote GDP and welfare. However, these policies reduce the environmentally positive impact of the carbon tax and even induce an increase in emissions in some cases.

This paper studies the pure impacts of a carbon tax, it also simulates the impact of several recycling policies where the increased tax revenue is incorporated. Thereby, this research supports to design and implement carbon tax policies in Vietnam. This paper also would contribute to the literature an example of the adoption of the carbon tax in a developing country, and it could be a lesson for others with similar conditions. Compared with previous models, the proposed model in this paper is a fairly standard CGE approach that tries to picture the economic system of Vietnam. In addition, a more flexible carbon tax mechanism is proposed to improve adequate coverage of emission resources.

The aim of this empirical study is to investigate an integrated model that captures the way service quality of banking kiosks (BK-SQ) exerts its impacts on customer perceived value and customer satisfaction and the moderating mechanism of technology readiness (TR) in the quality–satisfaction relationship in the banking sector in Vietnam.

An offline survey was conducted to obtain responses from 604 users of banking kiosks in Vietnam. Exploratory factor analysis, confirmatory factor analysis and structural equation modeling were used for data analysis. The moderating effect of TR was examined following the product indicator method.

The results validate significant positive correlations between BK-SQ, customer perceived value and customer satisfaction. Among six service quality dimensions, convenience is the most significant factor in predicting perceived service quality. The study also delineates how TR can moderate the link between service quality and customer satisfaction.

Future studies may make further attempts to incorporate other human and demographic factors as a moderator into the research model.

Bank managers should strive to improve the operations of banking kiosks based on six aspects and increase TR levels of customers to boost customer satisfaction with banking kiosks.

The study contributes to the literature on service quality and self-service technologies (SSTs) by offering critical insights into how banks can make use of influence mechanisms in the model to enhance service quality and customer satisfaction.

Groundwater plays a critical part in both natural and human existence. When surface water is scarce in arid climates, groundwater becomes an immensely valuable resource. Dak Lak is an area that frequently lacks water resources for everyday living and production, and the scarcity of water resources is exacerbated during the dry season. As a result, it is critical to do study and understand about groundwater to meet the region's water demand. This study aims to extend the use of the MODFLOW model for groundwater simulation and assess the overall groundwater reserves and water demand in the highland province Dak Lak.

The MODFLOW model is used in this work to compute and analyze the flow, prospective reserves of groundwater from which to plan extraction and estimate groundwater variation in the future.

The application of the MODFLOW model to Dak Lak province demonstrates that, despite limited data, particularly drilling hole data for subterranean water research, the model's calculation results have demonstrated its reliability and great potential for use in other similar places. The use of the model in conjunction with other data extraction modules is a useful input for creating underground flow module maps for various time periods. The large impact of recharge and evaporation on groundwater supplies and water balance in the research area is demonstrated by simulations of climate change scenarios RCP4.5 and RCP8.5.

None of the studies has been done previously to analyze water resources of Dak Lak and the scarcity of water resources is exacerbated during the dry season. Therefore, this study will provide useful insights in the water resource management and the conservation of Dak Lak. The groundwater in Dak Lak can meet the area's water demand, according to the results obtained and water balance in the study area. However, the management of water resources and rigorous monitoring of groundwater extraction activities in the area should receive more attention.

This study aims to explore the pathway of increasing hotel booking intentions by mapping the linkage mechanism between the antecedents and components of brand equity to ultimately drive followers’ hotel booking intention. In addition, the role of over-endorsement as a moderating variable is also evaluated.

The conceptual model and research hypotheses were each assessed using covariance-based structural equation modeling. Paper-based and online surveys were used to collect data from 443 respondents who are TikTok users and follow at least one TikTok online celebrity, while that online celebrity must have reviewed at least one type of accommodation.

Except for the relationship between virtual interactivity and online celebrity brand image, the results confirmed the relationships between research concepts.

Further studies are needed to validate the results in other cultural contexts, generalize findings and broaden the range of target respondents.

This study contributes to the hotel literature by illustrating how online celebrity brand equity (OCBE) drives hotel booking intentions. The study highlights the importance of antecedent factors – follower-centered drivers (e.g. lifestyle congruence, friendship) and online celebrity-led drivers (e.g. virtual interactivity, expertise) – to achieve a hierarchical relationship between OCBE components and followers’ booking intentions.

“The world needs science, science needs women” is the message given by UNESCO in the program for the development of women in science” (UNESCO, 2017). In Vietnam, women’s participation and achievements in scientific research is considered a great and important resource for industrialization and modernization. Even so, are there gender differences in scientific achievement in the social science research institutes in Vietnam? What factors influence the scientific achievement of female social researchers? The answers will be based on data from a 2017 survey with a sample of 756 researchers, of which 77.6% were female. The survey was conducted by the Vietnam Academy of Social Sciences, a leading, ministry-level national center for the social sciences in Vietnam. This chapter analyzed the scientific achievements of researchers through their position as principal investigators of research projects and their publications, and factors that may impact this. Bivariate and multivariate analyses of factors that may affect the scientific achievement of researchers found that gender differences in academic achievement in the social sciences in Vietnam was still prevalent. Female researchers’ scientific achievements were lower than those of their male counterparts. The contribution to science of Vietnamese female researchers was limited by many different factors; the most important were the academic rank of the researchers and gender stereotype that considered housework the responsibility of women.
