Corrosion of steel in marine environments poses a significant economic and environmental challenge because of its detrimental effects on marine structures and equipment. Traditional chemical inhibitors that mitigate corrosion often introduce harmful substances into the environment. As a result, there is a growing interest in exploring eco-friendly alternatives, such as plant-derived inhibitors, to reduce the environmental impact of corrosion protection strategies. The purpose of this study is to investigate the effectiveness of Phyllanthus urinaria extract as a green anti-corrosion additive for rebar steel in marine conditions.

Phyllanthus urinaria extract was prepared in the ethanol solution with the assistance of a sonicator. The steel’s surface upon addition of the extract was characterized using SEM, EDX and FTIR analysis. The electrochemical corrosion characteristics, including potentiodynamic polarization and electrochemical impedance spectroscopy, were used to evaluate the inhibitory performance of the extract on steel under simulated marine conditions (3.5% NaCl solutions).

The results of this study showed that with Phyllanthus urinaria extract’s content of 0.02% in NaCl solution of 3.5%, the corrosion rate decreased to about 30% compared to the controlled sample. Measurements of the inhibitory mechanism analysis study for all solutions from 0 mg/L to 1.114 mg/L of polyphenol from Phyllanthus urinaria extract showed a significant reduction in rebar corrosion rate, especially with 0.2228 mg/L polyphenol. Reinforcement can increase corrosion inhibition by up to 30% compared to the control sample.

To the best of the authors’ knowledge, this is the first study of using Phyllanthus urinaria extract as green inhibitor for protection of steel from the corrosion in the simulated marine solution. The protective mechanism for steel using Phyllanthus urinaria extract was investigated using the FTIR, SEM, EDX and electrochemical analysis. The results indicated that the polyphenols in the extract showed inhibition that could minimize the corrosion of reinforcement in marine environments.

This chapter provides information on the development of Vietnamese education under the influence of global forces based on the analysis of relevant education research and policies using Wolhuter’s frameworks. In the process of coming up with ways to develop education in the face of different influences of globalization, besides having reactions with patterns commonly found in countries around the world, Vietnam also has responses that reflect its own political, sociocultural and economic characteristics. The state still plays a controlling role in education at all levels and many culture-related features that have existed throughout the country’s history have hardly changed, namely aspects related to teachers, learners and teaching and learning methods. To sustain its education in the globalized era, Vietnam must make more efforts in various aspects such as the link between education and employment, the logic of education objectives, the feasibility and appropriateness of curricula, quality of education, especially of higher education and equality in education for underprivileged groups.

The purpose of this study is to investigate the impact of team psychological capital (PsyCap) on team innovation. The study also examines the mediating role of team learning, including exploratory and exploitative learning, in team innovation.

A sample of 272 team leaders of firms in Vietnam was surveyed to validate the measures via confirmatory factor analysis and to test the model and hypotheses using structural equation modeling.

The results demonstrate that team PsyCap has a positive effect on team innovation. Further, team exploratory learning mediates the relationship between team PsyCap and team innovation; however, team exploitative learning does not. Although team exploitative learning is explained by team PsyCap, it does not enhance team innovation.

The study findings suggest that, to enjoy a high level of team exploratory and exploitative learning and innovation, firms should develop team PsyCap. This could be undertaken by implementing leader–subordinate mentoring programs, together with creating a social context that helps in interacting and communicating among team members.

This study is among the first to examine the role of team PsyCap in team exploratory and exploitative learning and innovation, adding further insight to the literature on innovation at the team level.

This study explores the dynamics of companies’ green knowledge sharing (GKS) within the tourism sector, focusing on its influence on green electronic word-of-mouth (eWOM) intention via the mediation of tourists’ green engagement behaviour. Additionally, the study considers the moderating effects of green destination psychological ownership and perceived injunctive norms of green self-expression online on the pathway from green knowledge sharing to tourists’ green engagement behaviour to green eWOM.

The primary dataset, consisting of 902 valid responses obtained through time-lagged surveys administered to environmentally conscious tourists, was analysed using structural equation modelling (SEM) by PROCESS package for R.

Findings indicate that green destination psychological ownership enhances the mediation effect of tourists’ green engagement behaviour on green eWOM intention, reinforcing the sense of personal investment and belonging among tourists. Conversely, perceived injunctive norms of green self-expression online moderate this pathway by shaping the social norms and acceptability of green behaviours online.

To effectively spread green knowledge, tourism businesses should focus on enhancing tourists' psychological ownership of green destinations and align their communications with the perceived norms of green expression online. This strategy not only deepens tourists' environmental commitment but also stimulates active participation in spreading sustainable practices.

This study contributes to the green marketing literature by revealing how intrinsic and extrinsic motivational factors interact to influence green engagement and eWOM intention in the tourism industry, aiding marketers in strategically fostering green value co-creation and enhancing sustainable practices through targeted green knowledge sharing.

This study aims to investigate the relationship of employee motivation to team support, financial incentives and public sector motivation in various agencies under the Binh Dinh People's Committee in Vietnam. These agencies fulfil state management functions in many fields, such as investment, finance, construction, sports, culture and tourism.

This study applies the quantitative method to test team support, financial incentives and public service motivation (PSM) in relation to employee motivation in the public sector. The data are analysed using covariance-based structural equation modelling (SEM), with a sample size of 263 employees who work at provincial government agencies.

The study results show that team support, financial incentives and PSM have a positive influence on employee motivation in the public sector.

The findings provide theoretical evidence that team support, financial incentives and PSM are key predictors of employee motivation in the public sector in the context of an emerging economy. Consequently, the authors propose that managers in the public sector should motivate employees by communicating with employees about the employees' roles in improving the local people's lives to stimulate the PSM of employees. In addition, managers should always provide constructive feedback that recognises employees' achievements and pay bonuses based on job performance and successful projects to improve public service.

The purpose of this paper is to examine factors that shape the adoption of mobile phones for vegetable marketing by Vietnamese smallholders.

A structured questionnaire was given to 185 smallholders randomly chosen from 345 vegetable smallholders in the Vinh Thanh district of Vietnam. Descriptive statistics, inferential statistics and a binary logistic regression were applied to analyse the data.

The research results show that the smallholders’ adoption of mobile phones for vegetable marketing is significantly affected by their number of extension contacts, distance from smallholders’ homes to local markets, community-based organisation participation, gender, training/credit programme participation, age, education level, income and farm size (χ² = 143,111, p < 0.000).

A combination of factors related to socio-economic, situational and institutional characteristics of smallholders should be considered when promoting smallholders’ uptake of mobile phones for vegetable marketing in developing nations.

This research provides useful insights into the determinants of mobile phone adoption for vegetable marketing by smallholders and highlights areas that need to be considered when designing policies to improve the uptake of information and communication technologies in developing countries.

In many countries, innovation in building design for improving energy performance, reducing CO2 emissions and minimizing life cycle cost has received much attention for sustainable development. This paper investigates the importance of optimization tools for enhancing the design performance in the early stages of Vietnam's cooling-dominated buildings in hot and humid climates using an integrated building design approach.

The methodology of this study exploits the non-dominated sorting genetic algorithm (NSGA-II) optimization algorithm coupled with building simulation to research a trade-off between the optimization of investment cost and energy consumption. Our approach focuses on the whole optimization problem of thermal envelope, glazing and energy systems from preliminary design phases. The methodology is then tested for a case study of a non-residential building located in Hanoi.

The results show a considerable improvement in design performance by our method compared to current building design. The optimal solutions present the trade-off between energy consumption and capital cost in the form of a Pareto front. This helps architects, engineers and investors make important decisions in the early design stages with a large view of impacts of all factors on energy performance and cost.

This is one of the original research to study integrated building design applying the simulation-based genetic optimization algorithm for cooling-dominated buildings in Vietnam. The case study in this article is for a non-residential building in the north of Vietnam but the methodology can also be applied to residential buildings and other regions.

Vietnam is an emerging economy in the South East Asia region. Its Generation Z is gradually taking the lead in the country. But rather than breaking away from the previous generations, this generation also shows a strong preference towards local values and solid commitment to social issues. Thus, traditional culture elements are increasingly integrated in every aspect of Generation Z’s life, such as advertising and fashion. Instead of hanging out at coffee places, they go for bubble tea. They still appreciate the traditional values but integrate them within a modern context. Brands chase after these young people by adapting their values into their products and services. In the work place, the Vietnamese Generation Z is less confident. They are partially lost in career development with poor career counselling in the education system. They desire new experience and new learning opportunities. Generation Z, who were born beginning in 1995, emerges in Vietnam as a fresh and promising force.

Vietnam is firmly committed to attaining the Sustainable Development Goals articulated in the United Nations 2030 Sustainable Development Agenda. Goal 4 concerns quality education, and target 4.3 refers to ensuring access by all men and women to quality and affordable technical, vocational and tertiary education, including university education. In 2017, the Prime Minister issued a directive that included five actions to be taken by Vietnam’s Ministry of Education and Training to achieve target 4.3 in the context of the higher education sector. This chapter provides an opportunity to review some challenges the Ministry faces in implementing the five actions specified.

This paper aims to examine the management status quo of archaeological heritage in Vietnam seen in the case of Vuon Chuoi, a complex of Bronze Age sites located in Central Hanoi, which has been believed to be Hanoi’s first human settlement. Like other archaeological sites located in urban areas, this site has been under threat of destruction caused by land encroachment pressure. Although researchers have long waged a campaign for preservation, the dissensus among key stakeholders and the dispute over responsibility have left this site at the heart of an interminable polemic over legislation.

This research utilises a qualitative approach, and the primary data were collected throughout multiple field trips in 2019 and 2020. Several open-ended interviews were conducted with various state and nonstate actors involved in the Vuon Chuoi Complex’s management process. The discussion was also supported by analysing related legal documents retrieved from national archives and official online directories.

This paper dissects the current legislative and administrative framework applied in governing heritage in general and archaeological sites in Vietnam, in particular. The results indicate that existing flaws in Vietnam’s legal system are detectable, and the unsystematic organisation has led to deferment of the decision-making processes. Also, there is an apparent difference found in the attitude of the bodies in charge toward the treatment of listed and unlisted sites.

This research outlines that in the wake of urbanisation and industrialisation in Vietnam, a consensus among key stakeholders and an inclusive legal system are required to help preserve archaeological sites in urgent need of attention. Although several Vietnamese laws and regulations have been put into practice, they have shown critical barriers and gaps in conserving Vietnamese cultural heritage.
