Truck appointment systems have been applied in critical container ports in the United States due to their potential to improve handling operations. This paper aims to develop a truck appointment system to optimise the total cost experiencing at the entrance of container terminals by managing truck arrivals and the number of service gates satisfying a given level of service.

The approximation of M_t/G/n_t queuing model is applied and integrated into a cost optimisation model to identify (1) the number of arrival trucks allowed at each time slot and (2) the number of service gates operating at each time slot that ensure the average waiting time is less than a designated time threshold. The optimisation model is solved by the Genetic Algorithm and tested with a case study. Its effectiveness is identified by comparing the model's outcomes with observed data and other recent studies.

The results indicate that the developed truck appointment system can provide more than threefold and twofold reductions of the total cost experiencing at the terminal entrance compared to the actual data and results from previous research, respectively.

The proposed approach provides applicably coordinated truck plans and operating service gates efficiently to decrease congestion, emission and expenses.

Vietnam is experiencing high rates of young adult migration from rural hometowns to urban cities in search of new economic and social opportunities. However, limited internal migration research has examined the well-being of this population once they are in the urban destinations, as well as their interactions with the new lifestyles in the cities. Thus, the purpose of this paper is to explore the social transition of young Vietnamese migrants into city life.

In-depth interviews were conducted among ten female and six male temporary unmarried migrants, between ages of 18 and 25 years, currently living in Ha Noi through purposive sampling.

Despite a higher income in the city, young migrants often suffer from physical and mental health strains that decrease their overall well-being, caused by the factors such as barriers to assimilation to new lifestyles, continued attachment to origin hometowns, financial pressures, and poor living conditions. Important aspects in pre-migration expectations and actual experiences influenced the psychosocial well-being of these young migrants as they transitioned into adulthood during their migration process. Migration to the city and assimilation into city life also changed young migrants’ views on lifestyles and behaviors often considered misconducts in their rural hometowns, such as premarital sex. Female migrants faced higher stigmatization compared to male migrants, often described by fellow migrants as becoming “loose” in the new city.

The study findings highlight the important gender-specific implications for health services and programs to improve young migrants’ well-being in the city.

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.

Management practices and competition levels have been shown as important factors affecting the performance of enterprises that do not include banks. The paper, thus, aims to measure management practices and to study the effect of management quality and competition level on the performances of the first-level branch of commercial banks in the context of the Viet Nam banking system.

The study employed the approach of Bloom and Van Reneen (2007) to quantify management practices of the commercial banks. The level of competition was measured by the number of competitors suggested by Nickell (1996) and the index suggested by Boone (2008). Finally, the effects of management practices and competition level on the bank performances were jointly estimated through a Cobb–Douglas production function, similar to the one used by Bloom et al. (2014).

The results show that the management practices score is, on average, above the average. While the management practices are found to positively correlate with profits, the competition level is found to significantly reduce bank profits.

Cross-sectional data limit the findings of the paper to a point of time. In the future, studies with panel data are desirable.

The findings of the study help bank managers to make more informed decisions about management practices. Any policy promoting new entrants to the banking market should be carefully considered.

The paper is the first to measure the management practices of commercial banks and to explore the impacts of management quality and competition level on bank performances.

This study aims to examine the accessibility, loan purposes and effects of informal credits on poor households in Northern mountainous Vietnam.

This study used primary data collected directly from surveying 402 poor households in Thai Nguyen province using a well-designed questionnaire. The probit model is employed to specify which factors affect access to informal credit, the tobit model is used to estimate the borrowing functions specified. In addition, descriptive statistical analysis is also used to describe the accessibility, purposes and effects of informal credit on poor households.

The results show that there is a considerably high proportion of informal borrowings from relatives, neighboring villagers, professional moneylenders, rotating saving and credit groups, trade credits and mortgages. Labor force ratio, social capital and residential land areas are the key determinants of poor households' informal borrowings. The purposes of borrowing are diverse. The informal loans also have certain significant effects on poverty reduction and the welfare of poor households.

The effects of the informal loans on house welfare should be quantitatively evaluated.

The findings from these analyses allow us to draw relevant policy implications for the development of rural finance in other low-income, developing countries.

This research contributes to the body of published literature in several ways. Firstly, it provides understanding of the performance of the informal financial subsector. Secondly, the informal subsector of rural finance is evaluated in close relation to the formal subsector.

The purpose of this paper is to identify risk patterns of road and bridge projects in Vietnam, where the construction market is emerging but attractive to construction organizations, especially foreign companies.

Using a questionnaire, experienced practitioners of various contractors were interviewed to collect risk-related data in terms of actual likelihood and impact from road and bridge construction projects in Vietnam. Using the collected data of actual likelihood and impact, the specific probability and impact of risk factors were determined for different types of road and bridge projects, including small and medium type, big type, government-funding type, and other-funding type (e.g. official development assistance funds, public-private partnership).

The results of analysis indicate the specific probability and impact of risk factors in four risk themes, including contractor-related, project-related, owner-related, and external risks. Actual risk patterns for different types of road and bridge projects in Vietnam were identified.

The identification of actual risk patterns could help practitioners to know which risk factors are severe in frequency and/or impact. Hence, they could establish proper strategies to manage risk-related problems of road and bridge projects, in which they are directly involved.

The findings of this study could provide construction companies, especially foreign companies, with a better understanding of real risk panorama in Vietnamese road and bridge construction. Hence, they could make effective improvements on risk management of road and bridge projects in Vietnam.

This study aims to examine the transmission mechanism of factors on the characteristic fluctuation of Vietnamese coffee bean export price (PVN).

Applying Markov switching–vector autoregressive model.

Significantly, the empirical results showed that the transmission of independent variables on PVN is non-linear, and the fluctuation of PVN is affected by many factors, especially PVN in the previous period. In addition, the effect of Robusta coffee price was the greatest with coefficient is 0.28785, and the correlation between PVN and it was also the highest in both regimes with coefficients are 0.5317 and 0.3959, respectively.

These obtained results are in accordance with reality, as Vietnam is the largest exporter of Robusta coffee in the world.

This paper aims to explore the Kinh and ethnic stakeholders’ participation and collaboration in tourism planning in Sapa, Vietnam.

The primary data collection involved semi-structured interviews with 33 key tourism stakeholders, and data were analyzed using qualitative content analysis.

The findings reveal that in terms of participation and collaboration in tourism planning, there is little difference between the Kinh and ethnic groups. Tourism planning is viewed as a top-down approach, and both groups at the community level have very limited participation in tourism planning activities. However, at the on-site management level, there are opposing views between high (Kinh) and low (ethnic) management levels about participation in tourism planning. Both groups recognize the need for interdependence regarding collaboration in tourism planning. They also share similar aspects in regard to facilitating and hindering their participation in tourism planning.

The limitations of this study include the use of a qualitative method, which limited the number of respondents. Future research could benefit from the application of quantitative research methods to include a greater number of local tourism stakeholders.

This study contributes to a better understanding of tourism planning in the Vietnamese context and has some practical implications for destination management and policymaking.

This is the first study to investigate the perspectives of Kinh and ethnic groups in term of participation and collaboration in tourism planning in the Vietnamese context.

Little is known about how religious beliefs can motivate consumers to behave more pro-environmentally. Drawn on an integrated model of the theory of planned behavior, the norm activation model and the self-determination theory, this study aims to explore the effects of religious beliefs (especially, karmic beliefs (KB) and beliefs in a just world (BJW)) on consumers' pro-environmental behavior.

A sample of 736 consumers recruited from the eight most populous cities in Vietnam using the mall-intercept survey approach and structural equation modeling (SEM) was utilized to test the hypothesized model and hypotheses.

The findings indicate that KB and BJW can increase consumers' green intrinsic motivation, which subsequently encourages them to engage in pro-environmental consumption. Moreover, awareness of consequences (AOC) and ascription of responsibility (AOR) serially indirectly inspire consumers' sustainable consumption through serial mediators, including personal norms (PN), attitudes toward green products and green purchase intention.

Based on the findings, some theoretical and managerial implications for pro-environmental consumption are provided.

The study offers fresh perspectives on the role of religious beliefs in pro-environmental research. Additionally, this study sheds new light on the marketing literature by integrating the theory of planned behavior (TPB) and norm activation model (NAM) with self-determination theory (SDT) to explore the underlying mechanisms and effects of psychological components on consumers' pro-environmental behaviors.

COVID-19 hits every country’s health-care system and economy. There is a trend toward using automation technology in response to the COVID-19 crisis not only in developed countries but also in those with lower levels of technology development. However, current studies mainly focus on the world level, and only a few ones report deployments at the country level. The purpose of this paper is to investigate the use of automation solutions in Vietnam with locally available materials mainly in the first wave from January to July 2020.

The authors collected COVID-related automation solutions during the first wave of COVID-19 in Vietnam from January to July 2020 through a search process. The analysis and insights of a panel consisting of various disciplines (i.e. academia, health care, government, entrepreneur and media) aim at providing a clear picture of how and to what extent these solutions have been deployed.

The authors found seven groups of solutions from low to high research and development (R&D) levels deployed across the country with various funding sources. Low R&D solutions were widely spread owing to simplicity and affordability. High R&D solutions were mainly deployed in big cities. Most of the solutions were deployed during the first phases when international supply chains were limited with a significant contribution of the media. Higher R&D solutions have opportunities to be deployed in the reopening phase. However, challenges can be listed as limited interdisciplinary research teams, market demand, the local supporting industry, end-user validation and social-ethical issues.

To the authors’ best knowledge, this is the first study analyzing the use of automation technology in response to COVID-19 in Vietnam and also in a country in Southeast Asia. Lessons learned from these current deployments are useful for future emerging infectious diseases. The reality of Vietnam’s automation solutions in response to COVID-19 might be a reference for other developing countries with similar social-economic circumstances and contributes to the global picture of how different countries adopt technology to combat COVID-19.
