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
The purpose of this paper is to expand and analyze deeply customer emotions, concretize the levels of positive or negative emotions with the aim of using machine learning methods, and build a model to identify customer emotions.
Design/methodology/approach
The study proposed a customer emotion detection model and data mining method based on the collected dataset, including 80,593 online reviews on agoda.com and booking.com from 2009 to 2022.
Findings
By discerning specific emotions expressed in customers' comments, emotion detection, which refers to the process of identifying users' emotional states, assumes a crucial role in evaluating the brand value of a product. The research capitalizes on the vast and diverse data sources available on hotel booking websites, which, despite their richness, remain largely unexplored and unanalyzed. The outcomes of the model, pertaining to the detection and classification of customer emotions based on ratings and reviews into four distinct emotional states, offer a means to address the challenge of determining customer satisfaction regarding their actual service experiences. These findings hold substantial value for businesses operating in this domain, as the findings facilitate the evaluation and formulation of improvement strategies within their business models. The experimental study reveals that the proposed model attains an exact match ratio, precision, and recall rates of up to 81%, 90% and 90%, respectively.
Research limitations/implications
The study has yet to mine real-time data. Prediction results may be influenced because the amount of data collected from the web is insufficient and preprocessing is not completely suppressed. Furthermore, the model in the study was not tested using all algorithms and multi-label classifiers. Future research should build databases to mine data in real-time and collect more data and enhance the current model.
Practical implications
The study's results suggest that the emotion detection models can be applied to the real world to quickly analyze customer feedback. The proposed models enable the identification of customers' emotions, the discovery of customer demand, the enhancement of service, and the general customer experience. The established models can be used by many service sectors to learn more about customer satisfaction with the offered goods and services from customer reviews.
Social implications
The research paper helps businesses in the hospitality area analyze customer emotions in each specific aspect to ensure customer satisfaction. In addition, managers can come up with appropriate strategies to bring better products and services to society and people. Subsequently, fostering the growth of the hotel tourism sector within the nation, thereby facilitating sustainable economic development on a national scale.
Originality/value
This study developed a customer emotions detection model for detecting and classifying customer ratings and reviews as 4 specific emotions: happy, angry, depressed and hopeful based on online booking hotel websites agoda.com and booking.com that contains 80,593 reviews in Vietnamese. The research results help businesses check and evaluate the quality of their services, thereby offering appropriate improvement strategies to increase customers' satisfaction and demand more effectively.

The paper aims to examine the impact of tighter banking regulation on banks’ loan loss provisioning in an emerging market context.
Abstract
Purpose
The paper aims to examine the impact of tighter banking regulation on banks’ loan loss provisioning in an emerging market context.
Design/methodology/approach
The authors exploit the adoption of the Basel II Accord in Vietnam as a quasi-natural experiment and use Difference-to-Difference (DiD) method to examine the impact of tighter banking regulation on Vietnamese banks’ provisioning during the period of 2010–2019.
Findings
The paper finds that affected banks (i.e. those taking part in the pilot adoption programme) manage to reduce their provisions significantly compared to their control peers in the post-adoption period. More importantly, this paper further finds that the affected banks manage their provisions primarily for incomes smoothing and signalling. This paper also finds that those banks expand their lending significantly and experience an increase in financial performance in the post-adoption period. Overall, the results provide supports for the “borrowing from the future” proposition that banks may perceive that a tighter banking regulation provides them with growth opportunities, so they have the tendency to manipulate their provisions to facilitate their current income.
Originality/value
This paper contributes to the established literature on the manipulation of bank provisioning as well as the impact of banking regulation, and especially Basel II on bank economic decisions. As compared to prior literature, the adoption of Basel II in Vietnam provided an ideal shock for us to conduct a DiD design to estimate the causal impact of tighter banking regulation on banks’ provisioning practices.

Abstract
Purpose
The purpose of this paper is to trace the way in which a popular ritual became one of Vietnam’s most important festivals, elevated as a celebration of national heroism and charts its gradual transformation in modern society.
Design/methodology/approach
This research focuses on the combination of a fertility rite and narratives of St Gióng based on nationalism or heroism created a special festival reflecting many traditional cultural characteristics of Vietnam and the Việt people and the transformation of St Gióng from a mythological to a national symbol of heroism in anti-invader history was recorded in texts.
Findings
The paper casts light on the mythologization and historicization of St Gióng in Vietnam’s particular historical context by decoding the Gióng symbol as a core element of the folktales and myths about St Gióng to understand the formation and development of St Gióng in the cultural history of Vietnam.
Research limitations/implications
The paper is not exploring the Gióng symbol within a larger cultural context of nationalism and ethnosymbolic approach in a comparison of national symbolism and heroism.
Practical implications
The paper includes implications for advised scholars to conduct further exploration of the symbol and myth of not only St Gióng in Vietnam but also Kubera in India and Vaisravana in China to connect Kubera, Vaisravana and St Gióng under the connection of literal myth and heroic symbol.
Social implications
The paper shows how processes of historicizing myth and mythologizing history are important features of Vietnamese socio-historical research.
Originality/value
The paper shows how a fertility rite became a historical festival and the figure of St Gióng became a symbol of patriotic heroism.

Abstract
Purpose
Over energy consumption is one of the causes of global warming and climate change. To deal with this issue, using energy-efficient appliances is strongly encouraged and cultivating consumer loyalty toward energy-efficient appliances is crucial for long-term sustainability. This study investigates the effects of multiple dimensions of perceived value on consumer satisfaction and three outcomes of consumer loyalty (i.e. willingness to pay a premium, repurchase intention and word-of-mouth intention), considering the moderating role of the product category.
Design/methodology/approach
Quota sampling based on age and gender and snowball sampling methods were applied to recruit 423 participants for this study. A combination of partial least squares structural equation modeling (PLS-SEM), importance-performance map analysis (IPMA) and necessary condition analysis (NCA) was employed to examine the proposed model.
Findings
Functional, price, emotional and environmental values positively impact consumer satisfaction, enhancing the three dimensions of consumer loyalty. The product category moderates the effects of perceived value dimensions on consumer satisfaction. Moreover, the IPMA results highlight that functional value and environmental value are the most essential but underperforming value attributes. The NCA results indicate that social value is a necessary condition for consumer satisfaction.
Originality/value
This study is one of the pioneers in integrating PLS-SEM, IPMA and NCA approaches to comprehensively unpack the relationships between perceived value dimensions, consumer satisfaction and consumer loyalty in the context of energy-efficient appliances. The findings offer theoretical and practical importance for academics, retailers, producers and policymakers to encourage consumer loyalty toward energy-efficient appliances.

Abstract
Purpose
This study aims to answer two questions: do self-efficacy and outcome expectations serial mediate the effect of entrepreneurial education (EE) on the intention to start a business? and how can the social cognitive career theory explain entrepreneurial intention (EI)?
Design/methodology/approach
This study is based on the social cognitive career theory to examine the effect of EE on start-up intention via self-efficacy and outcome expectations by a serial mediation model. A sample of 1,232 students in Vietnam and the structural equal modelling method was used to test the hypotheses.
Findings
The results of this study reveal that entrepreneurial self-efficacy (ESE) significantly mediates the effect of EE on the intention to start a business. Similarly, entrepreneurial outcome expectations (EOEs) mediate the association between EE and EI. Especially, the results of serial mediation analysis show that ESE and EOEs serially mediate the EE–intention relationship.
Originality/value
Under a new perspective of social cognitive career theory, the current study is expected to contribute to clarifying the gap in the relationship between EE and EI. In addition, this study also contributes to investigating the antecedents of ESE and outcome expectations and providing empirical evidence supporting the relevance of social cognitive career theory in explaining EI.

Abstract
Purpose
This study aims to reveal the impact mechanism of franchisor-owned resources, franchise relationship quality and franchisee's dynamic capabilities on franchisee performance, with the moderating role of cultural sensitivity.
Design/methodology/approach
The sample consisted of 290 middle managers and team leaders at 113 hotels and food and beverage settings participating in the international- and domestic franchises in Ho Chi Minh City, Vietnam. A partial least squares structural equation model (PLS-SEM) is used to analyse the data.
Findings
The result reveals that franchisor-owned resources, franchise relationship quality and franchisee's dynamic capabilities significantly impacted franchisee performance. Furthermore, cultural sensitivity has a beneficial role in the effect of franchise relationship quality on franchisee performance.
Originality/value
This study develops an integrated analytical framework of franchisee performance from the franchisee's perspective, contributing to integrating international business theory in franchising studies, namely the resource-based view, dynamic capability view and relationship-marketing theory.

Abstract
Purpose
Upgrading in global value chains (GVCs) has become a crucial strategy for enhancing competitive advantage and attaining higher profitability, especially among firms in developing countries. Drawn from the sociological approach, this study treats GVC upgrading as an entrepreneurial act and examines factors affecting firms' intention to move up in their chains based on the theory of planned behavior. The authors also further test the moderating effects of firms' knowledge about rule of origin and governmental supports on the intention-behavior gap.
Design/methodology/approach
In-depth interviews with eight Vietnamese business managers were implemented to support the development of hypotheses and measurement scales. Afterwards, the authors conducted a survey on decision-makers of 402 Vietnamese firms which currently have export-import activities to collect quantitative data for testing the hypothesized relationships.
Findings
The empirical results indicate that both attitudes, behavioral control and social norms have significant positive impacts on the intention to upgrade in GVCs. In turn, such intention could further activate actual behaviors to move up in their chains. However, those who have better knowledge about rule of origin and receive governmental supports either in terms of finance, credit or technology have a higher probability of demonstrating actual behavior to upgrade in GVCs once their intentions are formed than those who do not.
Practical implications
This research provides valuable implications for policymakers in accelerating firms' actions to upgrade within their chains, hence, actively enhancing not only organizational performance but also significantly contributes to the national economic development.
Originality/value
While most of the previous studies examine the preconditions for firms to participate and upgrade in their GVCs, there is limited attention on determinants of firms' own intention and actual behavior to upgrade in their chains once they have participated in the GVC. Specifically, this research not only contributes to the existing knowledge regarding factors affecting firms' intention to upgrade in their chains but also closes the gap between the intention and the actual GVC upgrading behavior.
