The purpose of this paper is to evaluate the influence of VND/USD exchange rate on Vietnamese coffee export price (PVN).

The study uses cointegration test, Granger causality test and vector autoregression (VAR) model.

The results reveal that there is no co-integrating equation between two variables. It means the exchange rate does not have an effect on PVN in the long run. Furthermore, there is one Granger causality relationship between VND/USD exchange rate and PVN in the short run, but not vice versa. The study suggests that the first previous period of PVN is the most closely related variable which has the greatest impact on the variation of PVN among the selected variables, meanwhile the effect of VND/USD exchange rate on it, contrarily, is positive and very trivial.

In overall, the impact of VND/USD exchange rate on Vietnamese coffee export price (PVN) has been analyzed deeply in this research by applying new approaches.

The purpose of this paper is to develop lightweight actuators in order to replace conventional hydraulic/pneumatic actuators and to apply the actuation system to a small flying vehicle.

A new type of control surface using a piezo‐composite actuator for a small flying vehicle has been designed and manufactured. The piezo‐composite actuator is composed of a piezoelectric ceramic layer, a carbon/epoxy layer and glass/epoxy layers. Through this, the miniaturization and weight reduction of the actuation systems for flying vehicle can be achieved. A simple model of the control surface has been manufactured and evaluated through experiments.

The performance test results showed that the developed actuator can produce stable angle of attack independent of the applied loading. A radio controller for the actuator was developed to control the motions wirelessly. It was found that the piezo‐composite actuator and its integrated controller system have a possibility to be used not only as a small flying vehicle but also as a control surface actuator of a small unmanned flying robot through the miniaturization of power supply and control system.

The paper describes the procedures of designing and manufacturing smart structure application of the piezo‐composite actuator with performance evaluation and comparison method. It is expected that piezo‐composite actuator can be used as a small flying vehicle control surface actuator through the miniaturization of power supply and control system with the use of the integrated radio controller MIPAD.

The purpose of this research is to advance the conceptual and practitioner understanding concerning the maximisation of Industry 4.0 technologies industries in an emerging economy. The study first examines the internal resources that companies possess to implement Industry 4.0 effectively and, second, identifies the critical gaps that necessitate external resources, both at the industry and government levels.

The study embraces qualitative and inductive approaches with semi-structured interviews conducted with 112 company leaders representing nine industries and operating in various cities/regions of Vietnam.

The data analysis helped unveil 16 critical dimensions. Notably, the organisation-developed competences dimension illuminates the understanding regarding firms’ available internal resources, while the financial management and technological leap ability dimensions help explain firms’ required resources. More broadly, the business community unity and business community learning dimensions ascertain the significance of industry-level support, while the technological sponsorship and legal framework guide dimensions underline government support.

First, the study unpacks various key aspects of their daily, mid- and long-term operations associated with their current internal resources, gaps identified and the support they require to progress within the Industry 4.0 environment. Second, the study proposes a framework that advances the extant conceptual understanding of operational, strategic, managerial and production aspects among firms operating in an emerging economy. Third, it focuses on companies operating in nine industries in an emerging economy. Fourth, the study contributes to addressing various extant research gaps.

The purpose of this study is to examine the implementation of Industry 4.0 (I4.0) through the lens of the dynamic capabilities framework. Contrary to most existing research, this study chooses a cross-national viewpoint, exploring companies operating in two emerging economies.

Semi-structured interviews were conducted with 80 company managers operating in eight industries in Vietnam and Bolivia. The chosen inductive analysis was supported by qualitative content analysis and data structure.

The analysis reveals 13 conceptual dimensions. For instance, sensing opportunities underlines tangible and intangible “direct prospects”, such as enhanced accuracy, speed and cost effectiveness, whereas “operational management pressures” (sensing threats) identify the dilemma of changing individuals’ mindset, recruitment and addressing financial needs. While there is an overall agreement in key dimensions, differences between managers from both countries also arise, including staff’s adaptation and constant upskilling.

Empirically, this study responds to calls for cross-national studies investigating I4.0 initiatives. In doing so, the data gathered from company managers engaged in business in emerging economies afford new perspectives, with practitioner value. Theoretically, the numerous dimensions emerging from the data analysis provide useful conceptual insights to understand managerial aspects in considering and adapting to I4.0 expectations and requirements. These insights are reinforced by the development of a conceptual model that illuminates the initiatives, efforts and challenges of embracing this phenomenon.

The purpose of this study is to gain a more nuanced understanding of the relationship between a national product (coffee) and gastronomy. Moreover, incorporating the resource-based view of the firm framework, the importance of coffee is examined, as is the extent and potential to “marry” coffee and gastronomy into a tourism activity, and the need to develop such potential.

Semi-structured, face-to-face and online interviews were used to gather the viewpoints of 79 chefs and coffee shop owners/managers operating in Vietnam, the world’s second-largest coffee producer and home to a vibrant coffee shop industry.

The selected inductive analysis identified 11 dimensions, including “coffee infrastructure”, “coffee-based innovation”, “coffee-trigger” and “coffee resources”, emerged. These dimensions reveal a strong potential for a coffee and local gastronomy “marriage”. Furthermore, nine of the 11 dimensions provide direct guidance concerning the importance, the potential for “marriage”, coffee tourism development and what is needed to fulfil this potential.

The study affords understanding of Vietnam’s coffee industry, in particular its resources, and how these can be leveraged to combine with the nation’s gastronomy and produce more fulfilling food and beverage experiences.

Gastronomy, hospitality and tourism represent a well-defined partnership that can result in memorable consumer experiences. While the strength of this partnership is recognised, little is known about the potential to “marry” a national product such as coffee and local gastronomy. The study breaks new ground in this area and concludes with various theoretical and practical implications that contribute to more understanding of the coffee–gastronomy relationship.

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.

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.

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.

This research provides crucial strategic implications for restaurant managers when it comes to serving traditional foods for different generations.

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.

Drawing on the Theory of Planned Behavior, this study aims to explore the role of individual digital competencies, encompassing information and data literacy, communication and collaboration, safety and security, and problem-solving, in shaping cognitive determinants and influencing digital entrepreneurial intentions as well as investigates the moderating effect of performance expectancy of AI solutions on the relationship between digital competencies, cognitive determinants, and digital entrepreneurial intention.

Using a sample of 1326 MBA students in Vietnam with a stratified sampling approach, the second-order PLS-SEM is used to test the formulated hypotheses rigorously.

The study reveals that individual digital competencies, sculpted by information and data literacy, communication and collaboration, safety and security, and problem-solving, significantly impact cognitive determinants (attitude towards digital entrepreneurship, subjective norms, and perceived behavioral control), influencing digital entrepreneurial intentions. Performance expectancy of AI solutions also plays a crucial moderating role, enhancing the relationship between digital competencies and digital entrepreneurial intention.

Some practical implications have been recommended for policymakers, educators, and entrepreneurs.

This research provides original empirical findings, validating the impact of a varied array of digital competencies on entrepreneurial mindsets/cognition and intentions. The introduction of performance expectancy of AI solutions as a moderator introduces a nuanced dimension to comprehending the interaction between technological skills and entrepreneurial intentions.

From the customer-relationship theory and attachment theory approaches, this study proposes a serial mediation model to examine how celebrity attachment influences event attendees' intentions in the celebrity endorsement process in the context of events.

Paper-based and online surveys were used to collect data from 759 Vietnamese respondents, aged 15 and above, who followed domestic or international celebrities and were interested in various events taking place in Vietnam. A serial multiple mediation model was evaluated through covariance-based structural equation modeling.

The results confirmed the cognitive, affective and hybrid cognitive-affective pathways among antecedents, celebrity attachment and event participation intentions.

Future studies need to validate these findings across diverse cultural settings and larger participant pools to enhance their applicability. Exploring celebrity endorsement for events from an international follower perspective could offer valuable insights. Future research should consider these factors when interpreting results. It may benefit from conducting longitudinal or mixed-method studies to improve generalizability. Additional moderating variables are necessary, as research on the celebrity endorsement process for events evolves.

This study contributes to the literature on celebrity endorsement within event marketing, emphasizing the customer-brand relationship and attachment theory. It extends existing research that primarily examines how celebrity attachment influences event attendees' intentions in the celebrity endorsement process by validating a serial mediation model.
