Abstract
Purpose
Public–private partnership (PPP) projects play a pivotal role in fostering infrastructure development in developing countries. This study aims to identify major barriers and critical success factors (CSFs) for PPP projects in Vietnam.
Design/methodology/approach
The study initially conducted an extensive literature review and interviewed industry experts to compile a comprehensive list of barriers and success factors. Subsequently, a survey involving 250 construction professionals was conducted to assess these identified factors. The research used both ANOVA test and hierarchical regression analysis to explore the relationship between participants’ characteristics and assessments.
Findings
The results could provide a valuable reference for practitioners by assessing barriers and CSFs in PPP projects. Specifically, the ANOVA analysis indicated a positive correlation between barrier assessment and participants’ experience, while the influence of participants’ sector on the evaluation was minor. Furthermore, the hierarchical regression analysis demonstrated that participants’ sector did not moderate the relationship between barrier assessment and industry experience.
Originality/value
This research contributes to the existing literature by offering empirical insights into barriers and CSFs specific to PPP projects in a developing country context. The findings highlight the crucial role of experienced professionals in ensuring PPP project success. Moreover, the study provides construction practitioners with a better understanding of the essential factors and supports the development of effective management strategies for future PPP projects.

Abstract
Purpose
Risks in implementing green building (GB) projects have emerged as a significant obstacle for GB development, especially in developing countries. In recent years, both academics and construction practitioners have paid considerable attention to the risks associated with GB. In this study, the authors aimed to create a comprehensive risk assessment model that considers three crucial risk features: impact level, probability of occurrence and risk manageability.
Design/methodology/approach
In the research, authors adopted the mean scoring and fuzzy synthetic evaluation method to assess GB risks. Based on expert assessments, this model can determine the significance of risk factors, risk groups and overall risk. Notably, this research applied the proposed model to assess GB risks in Vietnam by surveying 58 GB experienced professionals.
Findings
The findings revealed that GB risks are relatively high in Vietnam, implying that risk management is essential for GB projects to succeed. The results also showed that “lack of experience of GB designers” is the most critical factor, and “human resources risk in the design phase” is the top crucial risk group.
Originality/value
This study contributes a novel and practical model to help practitioners assess risks in GB projects. In addition, this research offers detailed GB risk evaluations in Vietnam and thus could be a valuable reference for construction practitioners and future studies.

Abstract
Purpose
Risks are considered a significant obstacle to Green Building (GB) development and have recently received significant attention from both construction practitioners and academics. This study aimed to identify critical GB risks and explore the relationship between participants' characteristics and risk assessment.
Design/methodology/approach
Firstly, a list of GB risks was developed based on a comprehensive literature review and interviewing GB experts. After that, a survey of 207 construction professionals was then conducted to validate these GB risk factors. Finally, this research adopted the ANOVA test and hierarchical regression analysis to examine the relationship between participants' characteristics and risk assessment.
Findings
The results provided a list of GB risks classified and evaluated according to the GB project life cycle and, thus, may serve as a helpful reference for GB practitioners. Notably, the ANOVA analysis revealed that risk assessment negatively correlates with participants' GB experience, while their industry experience does not affect risk assessment. Furthermore, the hierarchical regression analysis proved that participant roles do not moderate the association between risk assessment and GB experience.
Originality/value
This study contributed to GB literature by implementing empirical research on GB risks in a developing country. The results implied the essential role of professionals with rich GB experience in risk management in GB projects. Furthermore, this research could help construction practitioners understand GB risks adequately and thereby have better risk-management strategies for future GB projects.

Abstract
Purpose
The consolidation behavior of prefabricated vertical drain (PVD)-installed soft deposits mainly depends on the PVD performance. The purpose of this study is to propose a numerical solution for the consolidation of PVD-installed soft soil using the large-strain theory, in which the reduction of discharge capacity of PVD according to depth and time is simultaneously considered.
Design/methodology/approach
The proposed solution also takes into account the general constitute relationship of soft soil. Subsequently, the proposed solution is applied to analyze and compare with the monitoring data of two cases, one is the experimental test and another is the test embankment in Saga airport.
Findings
The results show that the reduction of PVD discharge capacity according to depth and time increased the duration required to achieve a certain degree of consolidation. The consolidation rate is more sensitive to the reduction of PVD discharge capacity according to time than that according to the depth. The effects of the reduction of PVD discharge capacity according to depth are more evident when PVD discharge capacity decreases. The predicted results using the proposed numerical solution were validated well with the monitoring data for both cases in verification.
Research limitations/implications
In this study, the variation of PVD discharge capacity is only considered in one-dimensional consolidation. However, it is challenging to implement a general expression for discharge capacity variation according to time in the two-dimensional numerical solution (two-dimensional plane strain model). This is the motivation for further study.
Practical implications
A geotechnical engineer could use the proposed numerical solution to predict the consolidation behavior of the drainage-improved soft deposit considering the PVD discharge capacity variation.
Originality/value
The large-strain consolidation of PVD-installed soft deposits could be predicted well by using the proposed numerical solution considering the PVD discharge capacity variations according to depth and time.

Abstract
Purpose
This paper aims to identify and discuss selected reasons for social media disengagement (SMD). Drawing upon two-factor theory, it is argued that the determinants of consumer disengagement may be different from those that enable consumer engagement. Accordingly, extrinsic factors of social media experiences (SMEs), subjective norms (SN), perceived anonymity (PA) and perceived credibility (PC) trigger previously engaged consumers to terminate their interactions with the brand on social media.
Design/methodology/approach
A quantitative survey targeting young members from one of the largest social media communities in Vietnam was used in 2018. A total of 387 completed questionnaires were used for data analysis using covariance-based structural equation modeling.
Findings
Results reveal that PC is the main driver of SMD. Moreover, PA, SME and SN are indirectly related to SMD via PC.
Practical implications
The study provides some strategic recommendations for brand managers to re-design user interaction with social media brand pages to improve consumer retention and minimize consumer disengagement.
Originality/value
While consumer engagement with social media has received much attention from practitioners and academics, a research gap exists around the “dark side” of consumer engagement in which consumers can disengage from their relationship with brand on social media. This disengagement can lead ultimately to the termination of the relationship between the consumer and the brand. This research contributes to marketing literature by providing empirical evidence for relevant constructs driving consumer disengagement from the brand’s social media pages.

Abstract
Purpose
With the advancement of technology, microlearning has emerged as a promising method to improve the efficacy of teaching and learning. This study aims to investigate the document types, volume, growth trajectory, geographic contribution, coauthor relationships, prominent authors, research groups, influential documents and publication outlets in the microlearning literature.
Design/methodology/approach
We adapt the PRISMA guidelines to assess the eligibility of 297 Scopus-indexed documents from 2002 to 2021. Each was manually labeled by educational level. Descriptive statistics and science mapping were conducted to highlight relevant objects and their patterns in the knowledge base.
Findings
This study confirms the increasing trend of microlearning publications over the last two decades, with conference papers dominating the microlearning literature (178 documents, 59.86%). Despite global contributions, a concentrated effort from scholars in 15 countries (22.39%) yielded 68.8% of all documents, while the remaining papers were dispersed across 52 other nations (77.61%). Another significant finding is that most documents pertain to three educational level categories: lifelong learning, higher education and all educational levels. In addition, this research highlights six key themes in the microlearning domain, encompassing (1) Design and evaluation of mobile learning, (2) Microlearning adaptation in MOOCs, (3) Language teaching and learning, (4) Workflow of a microlearning system, (5) Microlearning content design, (6) Health competence and health behaviors. Other aspects analyzed in this study include the most prominent authors, research groups, documents and references.
Originality/value
The finding represents all topics at various educational levels to offer a comprehensive view of the knowledge base.

Abstract
Purpose
The purpose of this paper is twofold: to explain access to formal and informal credit in agriculture of Vietnam; and to compare the effectiveness between regular econometrics and machine learning techniques.
Design/methodology/approach
The multinomial logit (MNL) regression model and the random forest (RF) technique are employed for comparison purposes. To avoid heteroskedasticity, the robust covariance matrix is computed to estimate the sandwich estimator which in turn provides an asymptotic covariance matrix for biased estimators. Additionally, multicollinearity is tested among independent variables with variance inflation factors less than 3. Adequacy approach and sensitivity analysis are used to determine relevant levels of predictors. For models comparison, statistical evaluation metrics including Cohen’s κ, mean absolute error, root mean squared error and relative absolute error are employed.
Findings
The discrepancy between sensitivity analysis and adequacy approach revealed that MNL is more compatible for explaining determinants of credit participation. Due to insignificant differences in the evaluation metrics between models, the winner of choice is undetermined. Among other determinants, collateral, farmsize, income, procedure, literacy and all risk variables stand out to be critical factors when deciding borrowing schemes. While financially literate farmers tend to acquire loans from both sources, borrowing decisions against different risk sources depend on risk type and famers’ own desire to borrow.
Originality/value
Results of the MNL model are more consistent with literatures, which reinforce the role of collateral in the local credit scheme. Besides, financial literacy and farmers’ perception on different risk sources also influence how farmers’ borrowing strategies vary among sources.

Abstract
Purpose
The purpose of this study is to explore the development of “social innovation (SI)” research within Higher Education Institutions (HEIs) context.
Design/methodology/approach
This paper explores academic databases (Web of Science/Scopus/Sage), to identify relevant papers focused on SI. Using a systematic literature review (SLR) with narrative-assessment approach, the “VOSviewer” tool is used to analyse relationships between themes/subthemes related to SI in HEIs. Additionally, Excel’s polynomial-trendline feature is used to track publication numbers over time.
Findings
This research identified five themes related to HEIs and SI trends, each exposing important aspects of higher education and SI, including “Sustainable Development; Social Entrepreneurship; Digital Transformation; Research; and Innovation Culture.” This research also identifies best practices of global universities and their SI programmes across 19 topics, including changes in publication volume since 1996.
Practical implications
The SLR reveals research gaps related to HEIs and SI trends that require further investigation. Each of these areas gives scholars/practitioners opportunities for in-depth investigation.
Social implications
The findings of this study encourage global HEIs to implement SI, become acquainted with the present themes and the programmes conducted by HEIs, recognise the importance of SI trends and fill HE provision gaps around SI.
Originality/value
This paper contributes to knowledge on the promotion of SI in HEIs and sustainable development, while identifying gaps for further research.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Originality/value
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.

Abstract
Purpose
The purpose of this paper is to concern the community festival of a Jing minority village in the China–Vietnam border area. Since it was designated as a national-level Intangible Cultural Heritage in 2006, the festival has undergone many changes. The festival has steadily expanded and evolved, assuming characteristics of globalization. How is the globalized character of the Wanwei festival manifested? What are the forces behind the elevation of this local festival onto the register of national events and how did it turn into an event organized by the township?
Design/methodology/approach
The paper is based on the results of the author’s research on the culture of Kinh people in Wanwei from 2000 to the present. From the anthropological approach, the author mainly uses method of participant observation and in-depth interviews. The author has observed the Wanwei communal festival from 2000 to the present, interviewing about 40 villagers in Wanwei in depth, they can be leaders, intellectuals, civil servants, officials or working people.
Findings
The paper is a case study of the new aspect of globalization of a village festival. The author argues that globalization can lead to a spread of global flows but in this process of globalization, villagers also want to define the local identity, they reinvent the tradition, rewrite history, create new nuances for the gods with many different purposes. Practicing the current Wanwei village festival is a vivid example of globalization from below and the politics of tradition.
Originality/value
The paper adds a theoretical dimension to current globalization research. The paper also points out the political, economic and social dynamics that govern the transformation of a village festival in particular and the village culture in general in the border areas. The paper is a testament to the dynamism and flexibility of villagers when participating in the current globalization process.
