Abstract
Purpose
This paper aims to explore how open innovation communities contribute to the adoption of building information modelling (BIM) in the construction industry.
Design/methodology/approach
The paper presents a cross-case analysis of two construction communities, buildingSMART Norway and the BIM Vietnam Community. Data were collected based on 21 semi-structured interviews conducted with industry experts actively engaged in these two communities. The theoretical basis for the study was open innovation and the institutional intervention model, which delineates institutional actions related to the adoption of new information technology.
Findings
The findings show both similarities and differences in the way in which the communities contribute to industrial practice. Both communities use similar knowledge channels and repositories but apply different approaches to innovation creation and diffusion. In addition, trust can support BIM innovation in the community context.
Originality/value
The comparison of buildingSMART Norway and the BIM Vietnam Community in accelerating BIM innovation allows for exploring how open innovation communities support BIM adoption in the construction industry. The findings provide insights for construction communities into creating and diffusing BIM innovation. In addition, the examples of gaining benefits from community innovation activities are useful for construction firms and practitioners.

Abstract
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.

Abstract
The research analyzes the convergence of several socioeconomic indicators in a sample of 137 countries over the period 1990–2019. Applying log t-convergence tests, it finds that socioeconomic indicators’ convergence is divergent. Measuring seven different indicators, there are only two indicators of life expectancy and access to the internet converging at the global level, while the remaining indicators of gross domestic product per capita (GDPP), foreign direct investment (FDI) inflow, urbanization, fertility, and CO2 emissions do not. An extension to sub-sample analysis by levels of income and clustering convergence clubs is employed to confirm the heterogeneity and complexity of development pathways among countries. There are several insights for researchers and governments regarding future research and policies, especially for the development of developing countries.

Abstract
Purpose
The use of an electroless nickel/immersion gold (ENIG) surface finish comes with the inherent potential risk of Black Pad failures that can cause fracture embrittlement at the interface between the solder and the metal pad. As yet, there is no conclusive agreed solution to effectively eliminate Black Pad failures. The case studies presented are intended to add to the understanding of the Black Pad failure mechanism and to identify both the plating and the subsequent assembly processes and conditions that can help to prevent the likelihood of Black Pad occurring.
Design/methodology/approach
Scanning electron microscope (SEM) analysis of exposed pad surfaces on failed PCBs demonstrated a “mud‐crack” appearance, which is a characteristic of the Black Pad phenomenon. In addition, energy dispersive X‐ray (EDX) analysis was used to identify the elemental composition of the fractured layer between the Ni3P and Ni3Sn4 inter‐metallic compound, confirming the presence of Black Pad.
Findings
Grain boundaries or “mud‐cracks” that can be clearly seen in a top view of the failed pad surface and corrosion spikes in the failed pad surface, as evident from the cross‐section sample, should be used as a guideline to confirm Black Pad failures. Maintaining an optimum and well‐controlled EN and immersion gold bath, in addition to good process control prior to nickel‐gold deposition is recommended as the best approach for minimizing the occurrence of Black Pad failures.
Research limitations/implications
Only Sn/Pb soldering processes using ENIG PCBs or package substrates were evaluated and discussed. Thus, the current case studies do not encompass Black Pad failures with lead‐free soldering.
Practical implications
The work reported provides guidelines that can be used to identify Black Pad occurrence. It also proposes relevant approaches for minimizing the possible occurrence of Black Pad.
Originality/value
The findings of these studies provide a basic understanding of the Black Pad failure mechanism. Subsequently, both the plating and the ensuing assembly processes and conditions that can help to prevent the likelihood of Black Pad occurrence were identified.

Abstract
A review of the existing literature on disasters, impact, local vulnerability, and adaptation indicates to the fact that recent increasing frequency of natural disasters (e.g., floods, storms, and drought) have increasingly caused impacts on a diverse set of physical and biological systems, especially for those living in the developing countries where their livelihood strategies rely on natural resources (McCarthy, Canziani, Leary, Dokken, & White, 2001; Selvaraju, Subbiah, Baas, & Juergens, 2006; Kumar, 2007; Cruz et al., 2007).

Abstract
Purpose
This study aims to apply the theory of planned behavior, the theory of stakeholders, the theory of technology acceptance to evaluate the factors that affect the application of integrated reporting in Vietnamese listed companies.
Design/methodology/approach
Quantitative research method was used through survey questionnaire. Research data is collected from 144 directors, accountants, administrators of companies listed on Vietnam stock market in the period 2020–2022. Multivariable regression analysis is performed with three independent variables: usefulness, ease of use and environmental influence. Dependent variable is intended to apply integrated report.
Findings
Research results show that all independent variables have a positive impact on the dependent variable. In particular, the environment influence variable has the largest impact (0.443), followed by the level of impact of Usefulness” variable and “Ease of use” variable are 0.243 and 0.241, respectively. The regression model manages to explain 52.8% of the impact of the factors on the application of integrated reports. An analysis of the differences between groups of enterprises by staff size and capital size is carried out, the results hereof show that large enterprises tend to apply more integrated reporting. From the research results, the authors propose recommendations to promote the application of integrated reporting in Vietnamese enterprises to gradually improve the quality of information disclosure, attract investment and accelerate international economic integration.
Originality/value
The study evaluates the current situation of integrated reporting of Vietnamese companies to understand the factors affecting the use of integrated reporting, from which to propose recommendations to promote the application of integrated reporting in Vietnamese enterprises to gradually improve the quality of information disclosure, attract investment and accelerate international economic integration.

Abstract
Purpose
The research objective is rooted in the principle of providing new insights and a collective perspective regarded as Supply Chain Quality Management 4.0 (SCQM4.0), an integration of all three concepts – Industrie 4.0, quality management and supply chain management.
Design/methodology/approach
A thorough review of historical developments and existing integration trends among Industrie 4.0, quality and supply chain approaches along with future research directions outlined in the main literature, was conducted. This work establishes a knowledge base on research topics, issues of integration and synergies with a concentration on the potential for deeper integration with supply chain operations.
Findings
This article not only introduced the term SCQM4.0 and proposed a definition for it, but also contributed a novel conceptual SCQM4.0 framework and evolutionary perspective through the SCQM4.0 maturation model. Stemming from the gaps, opportunities and benefits identified in the literature, the conceptual SCQM4.0 framework builds on the high potential of the SCQM4.0 constructs to achieve successful governance and implementation. Under the SCQM4.0 maturity framework, it provides a clear evolutionary path underpinned by the SCQM4.0 constructs.
Research limitations/implications
In the effort toward a successful SCQM4.0 implementation, the proposed SCQM4.0 maturity frameworks will be a “road map” for businesses to develop fully and actively in supply chain operations, bringing quality products and services for the company. Industry practitioners are encouraged to perform gap analysis and direct the implementation of the strategy to establish an excellent SCQM4.0.
Originality/value
This is one of the pioneering studies integrating all three concepts (Industrie 4.0, quality management and supply chain management), connecting the link and discovering more synergies to support the future development of more holistic management models. SCQM4.0 is expected to expand on the strengths, synergies and established relationships between technologies 4.0, quality and supply chain, contributing toward a pioneering and quality supply chain.

Abstract
Purpose
Service-oriented architecture is an emerging software architecture, in which web service (WS) plays a crucial role. In this architecture, the task of WS composition and verification is required when handling complex requirement of services from users. When the number of WS becomes very huge in practice, the complexity of the composition and verification is also correspondingly high. In this paper, the authors aim to propose a logic-based clustering approach to solve this problem by separating the original repository of WS into clusters. Moreover, they also propose a so-called quality-controlled clustering approach to ensure the quality of generated clusters in a reasonable execution time.
Design/methodology/approach
The approach represents WSs as logical formulas on which the authors conduct the clustering task. They also combine two most popular clustering approaches of hierarchical agglomerative clustering (HAC) and k-means to ensure the quality of generated clusters.
Findings
This logic-based clustering approach really helps to increase the performance of the WS composition and verification significantly. Furthermore, the logic-based approach helps us to maintain the soundness and completeness of the composition solution. Eventually, the quality-controlled strategy can ensure the quality of generated clusters in low complexity time.
Research limitations/implications
The work discussed in this paper is just implemented as a research tool known as WSCOVER. More work is needed to make it a practical and usable system for real life applications.
Originality/value
In this paper, the authors propose a logic-based paradigm to represent and cluster WSs. Moreover, they also propose an approach of quality-controlled clustering which combines and takes advantages of two most popular clustering approaches of HAC and k-means.

Abstract
Purpose: To explore emotional support, daily housework assistance, and economic support for older adults provided by the Vietnamese family within the context of the impacts of socio-economic, demographic, and other factors.
Methodology: (1) The researchers used data from censuses taken from 1989 to 2019; national surveys of Internal Migration, Labor and Employment and other topics; and recent large sample sociological surveys (2) adapted a modified Diamond Care Model (Ochiai, 2009) to analyze effects of the characteristics of older adults; and of the country’s laws, policies, and socio-economic changes, on the families’ caregiving activities supporting the older adults.
Findings: The family is still the most important institution providing care for older adults in Viet Nam. Most older people live with their children and see this as an age-old security solution despite differences related to lifestyles and interests. However, when the average number of working-age people per older person decreases, as older adults live longer, household sizes are smaller, and there is increased large migration, the demand for non-family caregiving for older adults will increase. Since social services to help meet this demand are limited, the traditional family support system for the elderly in Viet Nam will face many challenges as families try to assure the quality of care needed in the very near future.
Value: This chapter shows systematically a relationship between elderly care in the Vietnamese family and socio-economic, demographic, and associated factors based on comprehensive data sources. The results can help us think about how to create an appropriate future model for taking care of older adults in Viet Nam that combines the efforts of families and the support of comprehensive social policies by the community.

Abstract
Purpose
In the wake of severe socio-economic damage, many firms have made creative and technological progress in their responses to the COVID-19 crisis. This paper examines internal and external environmental complexity elements as antecedents of business responses and builds a framework for tourism firms to respond to the pandemic crisis.
Design/methodology/approach
This study obtained survey data from 395 respondents in the Vietnamese tourism and hospitality industry. A partial least squares structural equation modeling–artificial neural network approach was used to examine various combinations of internal and external environmental complexity elements that have different impacts on business responses and firms' performance.
Findings
The knowledge and practice created by the firm's employees (individual creativity), obtained from traditional contexts (traditionality) were identified as internal environmental complexity factors while practice learned from other firms (mimetic pressure), information processing (status certainty) and digital transformation (digital technology speed) were treated as external environmental complexity factors. Internal and external environmental complexity factors influence business responses and firms' performance positively but differently.
Practical implications
This study demonstrates that firms should integrate their internal environment of creativity and traditionality with external environmental factors of mimetic pressure, status certainty and digital technology speed to create better business responses, and thus firm performance in the COVID-19 era.
Originality/value
This investigation contributes to environmental research and narrows the existing research gap relating to the association between types of environmental complexity and firms' responsive action, which then influence firms' performance in terms of sustainable competitiveness.
