Abstract
This paper describes the effect of factors on the strength characteristics of cement treated clay from laboratory tests performed on cement mixed clay specimens. It is considered that several factors such as soil type, sample preparing method, quantity of binder, curing time, etc. can have an effect on strength characteristics of cement stabilized clay. A series of unconfined compression tests have been performed on samples prepared with different conditions. The results indicated that soil type, mixing method, curing time, dry weight ratio of cement to clay (Aw), and water‐clay to cement (wc/c) ratio were main factors which can have an influence on unconfined compressive strength, modulus of elasticity, and failure strain of cement stabilized clay. Unconfined compressive strength of soil‐cement samples prepared from dry mixing method was higher than those prepared from wet mixing method.

Abstract
Purpose
This study explored students' perspectives on designing and implementing the new clinical interprofessional education (IPE) module for chronic disease management at the primary care level in the Vietnamese context.
Design/methodology/approach
Students from seven different university-level healthcare programmes participated in a cross-sectional survey Course Experience Questionnaire-based study. Additionally, two open-ended questions were presented to gather qualitative data, mapping student perspectives. Statistical analyses and thematic analyses were performed.
Findings
The results show that students agree with quality statements about IPE design features, such as good teaching, clear goals and standards, appropriate workload, appropriate assessment and a blended learning approach. Answers to the open-ended comments pointed out the strengths of the IPE module in providing opportunities for interprofessional learning, improving interprofessional collaboration competencies, real-life interprofessional collaboration practice and continuous feedback from tutors. Students also reported weaknesses in the IPE module, including a lack of feedback on the care plan and logistics of the IPE module.
Originality/value
Students positively recognise key design features of the IPE module, combining classroom activities with standardised patient simulations, clinical practice and home visits. Chronic disease management at the primary care level is a suitable context for training students to work interprofessionally. The strengths and weaknesses identified by students could help in the redesign and future implementation of the IPE module in the Vietnamese context. They could inspire practices in Southeast Asian medical education and beyond.

This paper aims to explore the motivational factors and contextual facilitators of female entrepreneurs in Vietnam’s coffee industry and also the barriers facing them.
Abstract
Purpose
This paper aims to explore the motivational factors and contextual facilitators of female entrepreneurs in Vietnam’s coffee industry and also the barriers facing them.
Design/methodology/approach
This study adopts the grounded theory approach, using semi-structured in-depth interviews with 31 women entrepreneurs in the coffee industry in the rural Central Highlands of Vietnam.
Findings
This study found that necessity-driven factors play an important role in motivating female entrepreneurs to advance their careers. However, these factors may be transformed into the opportunity-driven motives. Furthermore, the findings suggest that Asia’s collectivism culture and family support significantly affect the success of the women entrepreneurs, although gender inequality is not perceived as a serious constraint in entrepreneurial activities.
Research limitations/implications
This study has implications for the literature of women entrepreneurs regarding motivations and contextual influences in agricultural and rural areas of Vietnam. However, the sample size is relatively small which limits the concept generation of the study. For further research, a larger sample size with different business sectors should be considered to generate more explicit findings.
Practical implications
The findings from this study can assist the policymakers in developing strategies and governmental policies to support the career advancement of women entrepreneurs and improving gender equality in Vietnam.
Originality/value
This study contributes to the literature about understanding the motives and the roles of socioeconomic contexts in women’s entrepreneurial activities in agricultural and rural areas.

Abstract
Purpose
The purpose of this paper is to show the adaptation of participatory concept: “from passive to active community” which is the key point to achieve successes of the case study project – a cultural village in Tam Thanh, Tam Ky, Quang Nam, Vietnam. Its achievements result from the employment of three principal steps including identifying core issues in the community, creating changes in human perceptions and living conditions, and demanding operation and maintenance of the community further. The project can seem to be an outstanding showcase for the applicability and possibility of other community projects around Vietnam.
Design/methodology/approach
The paper uses the previous community projects developed in Vietnam. However, they are less effective for the community in long-term due to ignoring/underestimating the role of local people. The case study is an impoverished residential neighbourhood in Tam Thanh, Quang Nam. The authors along with the colleagues observed and conducted the workshops on site to understand the problems, values and expectations of people and the land. The paper likes as a summary for achievements and lessons extracted from that field study. The comparison to the previous projects shows the efficiency of participatory design with the active involvement of the local community.
Findings
The practical experiences to find successes for the community projects in Vietnam: collaboration of experts, architects, volunteers and local people; classification of roles for groups of participants; the involvement of the local government. engagement of a collaborative relationship with the community under the patience, comprehension and sympathy of all members of the community; and role of the architects involving the projects should be supported for people’s participation to come up with the idea instead of proposing strict ideas.
Practical implications
The appropriate approaches on the right subjects and right time are the key of successes and sufficiency for the community projects, particularly to the impoverished neighbourhoods or places with sensitive issues. The Tam Thanh village is a typical example and its experiences can be disseminated for the other projects. It indicates the active and respectful involvement of like-minded people (experts, volunteers, sponsors, managers and in particular local people) is very important to achieve the final expected destination in the purpose for/by/with the community.
Social implications
The huge effect of community projects is directly on the local people. The approaching and understanding them is challenging. An achievable community project is that the real needs of the people are provided; they are aware of their roles and benefits; and finally, the values are retained and developed sustainably in long term. The community projects are characterised by the participation of many people in many different stages: analysis, design and implementation. Therefore, for the experts, volunteers and managers, they learn to listen to the voice of the local people and to avoid the forced thoughts and underestimation of local people’s involvement.
Originality/value
The value of the study is that the nature of participatory design method is shown through activities and results of the community project in Tam Thanh. The delivery from theoretical features to practical works is not easy and needs observation and understanding of local culture and life. Depending on each specific location, the application of this design theory is flexible and adaptive. An idea for every project is initiation; however, the participation of local people is key to the project’s achievement.

Abstract
Purpose
This study aims to investigate the determinants of public trust in e-government services (Te-GS) and participation in social media.
Design/methodology/approach
A quantitative cross-sectional field survey was used to collect primary data at the local government level in 11 cities, towns and districts in Tien Giang Province, Vietnam. The final data set of 529 respondents was analysed using SmartPLS4 to evaluate the measurement and structural models.
Findings
Perceived responsiveness, transparency and security have strong positive associations with Te-GS, whereas perceived accountability does not. Furthermore, perceived ease of use and perceived usefulness are positively associated with social media participation.
Originality/value
Although previous studies have examined citizen behaviour in the use of e-government services, the social media context has rarely been considered due to its novelty. This study adds to the knowledge of the antecedents of participation in e-government services in developing countries such as Vietnam. Furthermore, it provides a comprehensive framework for understanding participation intention that considers four elements of good governance theory and two elements of the technology acceptance model (TAM), thereby extending previous research on the effects of these variables on the adoption of e-government services.

Abstract
Purpose
This study combines the TAM and UGT frameworks to investigate how Vietnamese students' views of ChatGPT and intrinsic needs affect their intentions to use it for education (via variables including perceived ease of use, perceived usefulness, novelty, information seeking and academic content creation). We will employ TAM theory (Davis, 1989) and UGT theory to elucidate university students' motivations for utilising ChatGPT in Vietnam. Simultaneously, we aim to address the limitation stemming from data uniformity. Our research will make a substantial contribution to the understanding of researchers regarding the use of ChatGPT and its varied consequences as it grows and develops.
Design/methodology/approach
This study was conducted at a private university in Vietnam with an estimated population of 15,000 students. One of Vietnam’s top private information technology institutions requires its students to use a variety of information and communication technologies (ICTs) on a regular basis to facilitate and enjoy their academic pursuits (Ngo, 2024; Nguyen). Students who are familiar with ChatGPT and have access to it for educational purposes are the ones that were chosen. This research is a quantitative study that utilises primary data through a survey method. Participants answered a questionnaire online through the Google Form platform sharing via social media platforms from October to December 2023. The questionnaire was divided into two sections: the first contained screening questions and demographic information and the second had five-point Likert-scale questions that measured the study’s components. Two screening questions are used to separate out the intended responders. (i.e. “I have heard the name ChatGPT” and “I know about ChatGPT”) were set to find whether the participants had any knowledge of ChatGPT. If participants were unaware of ChatGPT, their responses were not included in the study. A total of 283 responses were received. The participant’s demographic information is shown in Table 1. It is believed that a sample size of more than 200 provides adequate statistical power for data analysis in structural equation modelling. It is evident that the 283-sample size in this study is adequate to evaluate the research hypothesis and the fitting model. 42.9% of the 283 research samples were made up of men, while 57.1% were women. Business administration accounted for 40.1% of survey respondents, followed by information technology (25.2%) and English language (14.5%). The average ChatGPT usage time of respondents was 56 min in a single use. The study sample’s average age is 20–72 years old.
Findings
The present study contributes to the existing AI chatbot literature in the educational industry in several ways. First, this study addresses a gap in the literature by investigating the factors that influence students’ ITU ChatGPT for educational purposes in Vietnam. Using the extended model, we investigated factors influencing students’ intentions to use ChatGPT. It integrates three motive factors of the UGT (ACT, IS and N) with the core factors of TAM (PeoU and PU). The integrated framework’s findings indicate that in a Vietnamese educational setting, ChatGPT is a novel technology that should be considered in conjunction with PU and PEoU.
Research limitations/implications
First, only Vietnamese students make up the research sample. To increase the relevance of the findings, it is advised that future research look at the study model in various geographic regions. Second, the present investigation’s constraints arise from the lack of clarity about the Chat GPT version utilised by the respondents, specifically whether it was the free or premium edition. Furthermore, the limited duration of the survey presents an obstacle to gathering thorough data. Due to their reliance on the particular features and functionalities of the Chat GPT version used, these restrictions may have an effect on the researcher’s objectivity. Furthermore, the limited survey time may curtail the coverage of the collected answers, particularly considering that our survey predominantly focuses on business administration students, thus limiting the diversity and richness of the gathered data. We recommend that future studies should conduct comparative research between different versions of GPT Chat, including free and paid variants that can provide valuable insights into potential differences in performance and results. Such analysis can provide a deeper understanding of the strengths and limitations of different GPT Chat versions. Third, because the study focused on behavioural intention, actual usage and post-usage behaviour may not be covered by the findings. To gain a deeper understanding of users' actual behaviour, we suggest doing research on their usage and post-usage behaviours.
Practical implications
The findings will assist service providers and legislators in determining critical variables and influencing students' incentives to use ChatGPT in educational settings that use constructivist teaching methods. As a result, the information will assist service providers in creating AI chatbots that are more user-friendly, visually appealing, efficient, safe and convenient for education. Governments, in conjunction with service providers, have the potential to significantly accelerate the adoption of AI-based chatbots by highlighting their ethical and sustainable use. The findings demonstrate that students' ITU towards ChatGPT is substantially impacted by PU and PEoU. It is recommended that service providers emphasize the advantages and ease of use of AI chatbots in order to draw new clients. Additionally, in order to promote ChatGPT or related technologies, marketers should concentrate on raising the technology’s perceived novelty value. This is because people are open to new technologies as long as they believe they are interesting and innovative.
Originality/value
ChatGPT is an advanced AI-powered chatbot that has the potential to advance and revolutionize the learning and teaching process. This study attempted to look at the elements that lead students to want to use ChatGPT from an academic standpoint by combining the UGT and TAM. For practitioners, academics and educators, the findings provide a solid knowledge of and encouragement for the sustainable use of such AI tools. Despite having important practical consequences, the study contains a number of limitations that indicate possible research gaps that should be filled by further investigation.

Abstract
Purpose
The purpose of this paper is twofold: first, to develop a performance evaluation framework for construction and demolition waste management (CDWM); second, to investigate feasible and effective strategies to improve the CDWM performance.
Design/methodology/approach
A review of the literature highlighted a lack of comprehensive research to evaluate CDWM performance of key project stakeholders, like owners, contractors and consultants. After the identification of 22 performance variables through a pilot study, a first questionnaire survey was conducted to investigate the views of respondents toward CDWM performance. The 132 responses were analyzed using factor analysis to determine specific CDWM performance factors, which formed a conceptual performance evaluation framework of CDWM. Furthermore, a practical index (PI) was proposed to integrate the feasibility and effectiveness of CDWM strategies. The values of PI were employed to prioritize CDWM strategies from data collected in a second questionnaire survey.
Findings
The validated results from factor analysis revealed that the conceptual performance evaluation framework of CDWM consists of six factors; and the attitude toward CDWM emerged as the foremost critical factor. The prioritization of PI values indicated that raising CDWM awareness among construction stakeholders was the most feasible and effective strategy for CDWM.
Originality/value
This CDWM performance evaluation framework is one of the first to holistically evaluate CDWM from key stakeholder perspectives. In addition, the PI firstly enables quantitative integration of the feasibility and effectiveness of CDWM strategies.

Abstract
Purpose
Travel destinations worldwide are seeking smart ways to reduce the negative impact of tourism, and the public bike rental service (PBRS) is one of them. To investigate the usage intention of this service among visitors, the author of this research employs an integrated approach consisting of two psychological frameworks: the Norm Activation Model (NAM) and the Technology Acceptance Model (TAM).
Design/methodology/approach
The integrated NAM-TAM model is implemented to conduct a survey (sample n = 777) with visitors to Hanoi, Danang, and Ho Chi Minh City regarding the factors underlying their intentions to continue using the PBRS TNGo.
Findings
Structural equation models suggested that: (1) the NAM-TAM can explain behavioural intention to use a smart PBRS. Perceived Usefulness (PU), Perceived Ease of Use (PE), and Awareness of Consequences (AC) have positive and significant impacts on Attitude Towards Using (AT) and, thus, on Behavioural Intention to Use (BI). Also, Personal Norms (PN) positively influence BI. (2) Among the four independent variables, tourists' AC produces the most potent effect on the intention to continue using a PBRS.
Research limitations/implications
This study can start a new research direction of combining the NAM with other theoretical frameworks to explain customer behaviour in the field of sustainable tourism practices. Future research should explore the proposed model based on comparisons of different tourists’ backgrounds, including nationality, length of stay, spending level, visiting purpose, etc.
Practical implications
This research provides strategic implications for destination management organisations in boosting the use of PBRS amongst tourists, contributing to the environmental sustainability targets of the tourism industry.
Originality/value
This study responds to the existing gap by examining both functional value (indicated by PU and PE) and perceived environmental/social value (proxied by AC) in forming tourists’ attitudes towards PBRS and their usage intention. Our study, therefore, actively contributes to the research stream of tourist behaviour in the field of sustainable tourism practices from the altruistic behavioural perspective.

Abstract
Purpose
This study investigates key factors that influence the utilization of the internet by internationalizing firms in one transition market, Vietnam.
Design/methodology/approach
A systematic sample of 306 internationalizing firms in Ho Chi Minh City was surveyed to test the theoretical model. Structural equation modelling was used to analyze the data.
Findings
This study finds that the two key concepts in the technology acceptance model (TAM), perceived usefulness and perceived ease of use of the internet, can be used to predict internet utilization by organizations. Market orientation is also a predictor of internet utilization. Learning orientation facilitates perceived usefulness and perceived ease of use of the internet by internationalizing firms, and hence its utilization.
Research limitations/implications
Further research is needed to investigate other antecedents as well as outcomes of internet utilization by internationalizing firms.
Practical implications
This study suggests that programmes for the assistance and training of internationalizing firms should promote the usefulness and ease of use of the internet, and foster market orientation and learning orientation, in order to stimulate them to use the Internet effectively in the pursuit of marketing success in international markets.
Originality/value
This study expands the explanatory power of the TAM in predicting the utilization of the Internet by internationalizing firms.
