Abstract
Purpose
The evolution of technology from the most recent industrial age to the technology era better known as Industry 4.0 resulted in greater demand for horizontal, vertical and end-to-end digital integration. Prior studies show that Industry 4.0 adoption majorly influences the sustainability aspects in a supply chain network. The purpose of this paper is to identify the Industry 4.0 enablers of supply chain sustainability and further attempt to propose a research framework to bridge the theoretical gaps.
Design/methodology/approach
In this research study, the authors have used a systematic literature review methodology in the field of Industry 4.0 and sustainable supply chain management. The list of papers was downloaded from Scopus (www.scopus.com) database. Through strict screening, only journal papers were selected for conducting the review of the literature.
Findings
The review brings out some interesting findings which will be helpful for the research community. There have been limited research in the area of managing supply chain network sustainability through Industry 4.0 technologies. The authors found only 10 papers out of a total of 53 papers which emphasize on smart manufacturing, smart production system, smart warehouse management system, smart logistics and sustainability. Most of the previous research studies have ignored the social aspects of supply chain sustainability. Finally, the authors identified 13 key enablers of Industry 4.0 playing an important role in driving supply chain sustainability.
Practical implications
The strategies for Industry 4.0 should be refined and detailed to develop economic and social systems that can act flexibly to sudden changes in the system. Top management must be convinced for prioritizing investment support and creating a system that can facilitate technology convergence. Managers must also act on new models of employment and frame plans to continuously improve the system. In addition, managers must focus on establishing a collaborative platform to facilitate high-tech research and developments. Finally, it is essential to develop a performance management system for monitoring all actions in the supply chain network.
Originality/value
Integrating two independent subjects is the uniqueness of the current study. Here, Industry 4.0 and supply chain sustainability have been integrated to build the research framework, and in such a process, the authors have extended the existing knowledge base.

Abstract
Purpose
One‐dimensional pipe network flow analysis can be used in many applications to satisfactorily solve various engineering problems. The paper aims to focus on this.
Design/methodology/approach
A hybrid nodal method is detailed, which solves the pressure field prior to the elemental flows, and models both compressible gas and incompressible liquid and gas flows.
Findings
The results obtained by the algorithm were verified against a number of published benchmark flow problems. The methodology was found to yield accuracy similar or improved, compared with that of others, while being applicable to both incompressible liquid and compressible gas flows. Convergence performance was found to be similar to other hybrid techniques.
Originality/value
All flows are modelled via a single governing equation set. In the case of incompressible flow, the method is capable of dealing with both constant and variable cross‐sectional area ducts. The latter includes geometrically complex pipes such as sudden expansions.

Abstract
Purpose
This paper intends to investigate the empirical link between governance and energy investment in PPP. To succinctly account for biases in the fixed effects (FE) model, the authors adopted different bias-corrected techniques. The majority of these techniques provided evidence that PPP investments in energy are boosted by increasing the desire for accountability, prioritising the voice of the masses and disabusing the rule of laws. This study could not find any positive influence from the control of corruption to PPP investment in energy.
Design/methodology/approach
The acute shortage of power supply in SSA has attracted PPP investments in the energy subsector of the economy, leading to the recent debate on governance and public, private investment. The authors contributed to this argument by examining the impact of country governance on PPP investment in energy using a sample of countries in SSA.
Findings
Therefore, the authors concluded that low control of corruption is responsible for the inadequate volume of PPP investments. In the light of this, the government should redefine the anti-corruption bill of their sovereignty to accommodate severe sanctions when necessary.
Originality/value
This paper uses the fixed effects (FE) model by introducing batteries of nonlinear panel models to capture the relationship between the impacts of country governance on PPP investment in energy.

Abstract
Purpose
This study aims to investigate the Malaysian Mah Meri Indigenous tourism entrepreneur’s personality, experience, sense of community traits and current challenges in community-based tourism (CBT)-related businesses.
Design/methodology/approach
Semi-structured interviews were conducted to gather data from 10 Indigenous tourism entrepreneurs. Data were analysed using the NVivo 11 software.
Findings
The qualitative content analysis found three broad themes. Firstly, the authors found that the Mah Meri community possesses unique self-efficacy personality characteristics, significantly predicting their unsustainable entrepreneurial behaviours. Secondly, they are willing to share their values, beliefs and interests in their business offerings, which reflect their sense of community. Even with considerable entrepreneurial experience through learning from local wisdom and upskilling efforts by the government, the authors found that the community limitation mainly concerns the lack of early education, uninventive entrepreneurship practices and financial assistance.
Practical implications
This study provides an improved understanding of the Indigenous business environment for policymakers and Indigenous entrepreneurs. We found entrepreneurial personality, experience, sense of community determine and structure their CBT entrepreneurial activities.
Originality/value
This study provides a new perspective on Indigenous tourism entrepreneurs’ personalities, experiences, sense of community traits and challenges. The study also suggests encouraging sustainable Indigenous entrepreneurship practices for economic development, self-determination and community sustainability.

Abstract
Purpose
The purpose of this study is to present a new failure mode and effects analysis (FMEA) approach based on fuzzy multi-criteria decision-making (MCDM) methods and multi-objective programming model for risk assessment in the planning phase of the oil and gas construction projects (OGCP) in Iran.
Design/methodology/approach
This research contains multiple steps. First, 19 major potential health and safety executive (HSE) risks in OGCP were classified into six categories with the Delphi method. These factors were distinguished by the review of project documentation, checklist analysis and consulting with experts. Then, using the fuzzy SWARA method, the authors calculated the weights of major HSE risks. Subsequently, FMEA and PROMETHEE approaches were used to identify the priority of main risk factors. Eventually, a binary multi-objective linear programming approach was developed to select the risk response strategies, and an augmented e-constraint method (AECM) was used.
Findings
Regarding the project triple well-known constraints of time, cost and quality, which organizations usually confront, the HSE risks of OGCP were identified and prioritized. Also, the appropriate risk response strategies were also suggested to the managers to be adopted regarding the situations.
Originality/value
The present research points at the HSE risks’ assessment integrating the fuzzy FMEA, step-wise weight assessment ratio analysis and PROMETHEE techniques with the AECM. Further to the authors’ knowledge, the quantitative assessment of the HSE risks of OGCP has not been done using the combination of the fuzzy FMEA, MCDM and AECMs.

Abstract
This chapter reviews successful pedagogical interventions in teaching literacy in languages of teaching and learning in the upper primary grades in low- and middle-income countries (LMICs) and explores how researchers and teachers decolonized classroom spaces to ensure student achievement of learning outcomes. Themes emerging from the analysis of data are biliteracy interventions, interventions in official and national languages, teacher professional development, and ecological interventions. Results of the review indicate that researchers decolonized classroom spaces by using student linguistic repertoires, evidence-based pedagogical strategies student cultural capital and engaging families and communities. The review also reveals that more research needs to be conducted on teaching and learning in upper primary grades. The linguistic diversity of LMICs provides rich contexts for more research in bilingual education and L2 acquisition which could be useful worldwide as stakeholders in the education process explore the best ways to improve learning outcomes in schools.

Abstract
Purpose
The Iron Triangle, also called the Triple Constraint, is a central concept to project management research and practice, representing the relationship between key performance criteria. However, there is disagreement about which criteria should be represented on the vertices of this triangle. The purpose of this paper is to explore which concepts are part of the Iron Triangle, and how these concepts have changed over time.
Design/methodology/approach
This paper explores 45 years of project management research, drawing on a database of 109,804 records from 1970 to 2015. Three corpora were constructed, representing the project management and Time, Cost, and Quality Management literature. Time and Cost are consistently identified as part of the Iron Triangle. However, the status of quality is contested. Key concepts in the project management literature were explored using scientometric research techniques, to understand the relationship between these concepts.
Findings
Significant links were found between Time, Cost, and Quality, verifying these concepts as the vertices on the Iron Triangle. These links were significantly stronger than links to alternatives, such as Scope, Performance, or Requirements. Other concepts that are core to the Iron Triangle were also identified, and how these have changed over time.
Originality/value
This research develops the understanding of a key project management concept by clarifying which concepts are part of the Iron Triangle, based on evidence of how the concept is used in research. This paper also reveals the context in which this concept is used, and how this has changed over the last 45 years.

Abstract
Literacy instruction for children with a disability is not highlighted as a priority in South Africa. This can be attributed to numerous reasons, amongst others: the focus on care of children with disability to the detriment of learning; the high number of children with disabilities who are currently out of school; the gradual change and movement towards inclusion despite policies being in place, poorly qualified teachers with limited knowledge regarding best teaching practices and limited experience of teachers in teaching functional literacy. However, the National Department of Education is attempting to address these factors by, for example introducing a compulsory year of schooling before Grade 1 commences (Grade R), developing work books for all learners in the foundation phase and making them available across the country as well as introducing a new national curriculum – Curriculum Assessment Policy Statement CAPS – with a stronger emphasis on literacy.
In this chapter I will briefly provide a contextual background to the South African context; then provide a short discussion of the challenges faced in this context and finally focus on the best practices that have some evidence in this context.
