Abstract
Due to the increasing size and complexity of construction projects, construction engineering and management involves the coordination of many complex and dynamic processes and relies on the analysis of uncertain, imprecise and incomplete information, including subjective and linguistically expressed information. Various modelling and computing techniques have been used by construction researchers and applied to practical construction problems in order to overcome these challenges, including fuzzy hybrid techniques. Fuzzy hybrid techniques combine the human-like reasoning capabilities of fuzzy logic with the capabilities of other techniques, such as optimization, machine learning, multi-criteria decision-making (MCDM) and simulation, to capitalise on their strengths and overcome their limitations. Based on a review of construction literature, this chapter identifies the most common types of fuzzy hybrid techniques applied to construction problems and reviews selected papers in each category of fuzzy hybrid technique to illustrate their capabilities for addressing construction challenges. Finally, this chapter discusses areas for future development of fuzzy hybrid techniques that will increase their capabilities for solving construction-related problems. The contributions of this chapter are threefold: (1) the limitations of some standard techniques for solving construction problems are discussed, as are the ways that fuzzy methods have been hybridized with these techniques in order to address their limitations; (2) a review of existing applications of fuzzy hybrid techniques in construction is provided in order to illustrate the capabilities of these techniques for solving a variety of construction problems and (3) potential improvements in each category of fuzzy hybrid technique in construction are provided, as areas for future research.

Abstract
This paper examines the relationship between participation and job performance. It also seeks to identify the impact of individual variables on the level of participation among managerial employees in the Public Service Department in Malaysia. Finally, it attempts to determine whether Porter and Lawler's (1968)‐expectancy model could represent an appropriate framework for studying employee participation. The results indicate that the level of perceived participation among managerial employees is high and that employee participation has acmoderate and positive relationship with job performance. The findings appear to match other studies conducted in the West, suggesting that these studies were not very much different across cultures. Managerial employees place equal importance on intrinsic and extrinsic outcomes. Employee participation could be better managed if employees possess certain critical factors. These include high job abilities, greater need for achievement, and a substantial amount of motivation. This study also suggests that Porter and Lawler's (1968) expectancy model is a suitable framework for studying employee participation.

This paper aims to examine the influence of individual and organizational variables on the career advancement of academics in Malaysian private universities.
Abstract
Purpose
This paper aims to examine the influence of individual and organizational variables on the career advancement of academics in Malaysian private universities.
Design/methodology/approach
A correlation study was conducted in six private universities. Data were collected using a structured self‐administered questionnaire. The dependent variable was academics' career advancement and the independent variables were individual and organizational factors. Using stratified random sampling, 105 full‐time academics were chosen as the study respondents. They represented sampling criteria such as pure science and social science disciplines, job positions and academic qualifications.
Findings
Regression analysis showed that organizational variables, specifically mentoring, social network and organizational support, were the significant contributors to the career advancement of the academics with 56.1 per cent explanatory power. These results are useful to human resource development (HRD) personnel of the universities as guides for them to plan and implement HRD initiatives.
Practical implications
This study contributes knowledge to career advancement among academics in private universities. These institutions are rapidly expanding in Malaysia to cater to the needs of achieving the entrance of 40 per cent of the population into tertiary education by the year 2020. At the tertiary education level, HRD is important specifically to create better awareness among academics about their career planning and aspirations, the role organizational‐related factors have in their careers and how they should respond to the services given by the institutions.
Originality/value
The paper examines factors (limited to individual and organizational factors) that are of concern to HRD managers in managing the career advancement of academics in rapidly developing private universities.

Abstract
Purpose
This study aims to examine the relationship of work–family demands with employees’ well-being, and the role of management/supervisory support in this relationship. The following hypotheses were proposed: work–family demands would be negatively related to employees’ well-being; management/supervisory support would moderate the relationship of work–family demands with employees’ well-being.
Design/methodology/approach
The researchers used 250 working female academicians as respondents, working in the research universities in Kuala Lumpur, Malaysia. Their ages ranged from 30 to 60 years.
Findings
The findings of the present study proved that the work–family demands were negatively associated with employees’ well-being. Results also revealed that management and supervisory support strengthens the relationship between work–family demands and employees’ well-being. Thus, management and supervisory support plays an important role in balancing work demands and family roles and also in increasing working female academicians’ well-being.
Originality/value
In this study, management and supervisory support was found to be directly related to well-being, including life satisfaction, job satisfaction and family satisfaction. However, the direct relationship between management/supervisory support and well-being was positive and significant. This study also found that management/supervisor support reduced work–family conflict and work–family demands. Also, supervisory and management support was found to have a significant and positive relationship with well-being. Given these findings, supervisory and management support plays a very important role as a moderator of work–family demands and in developing and improving well-being in working women.

Abstract
Purpose
This paper aims to investigate the influence of religiosity on the relationship between abusive supervision and deviant work behavior (DWB). This paper examines whether the desire for revenge mediates the relationship between abusive supervision and DWB and whether the strength of this relationship is moderated by religiosity.
Design/methodology/approach
The proposed relationships were examined by collecting primary data from 350 employees using multistage sampling procedures. Hayes’ Process Macro was used to analyze the proposed moderated-mediation model of abusive supervision, DWB, religiosity and desire for revenge.
Findings
The analytical findings indicate that an employee’s desire for revenge mediates the relationship between abusive supervision and DWB. However, religiosity moderates the indirect effect of abusive supervision (mediated by the desire for revenge) on DWB.
Originality/value
To the best of the authors’ knowledge, this is the first study that explores the role of individual-level religiosity in mitigating the harmful effects of abusive supervision on deviant behavior and revenge in the workplace.

Abstract
Purpose
Despite long-term, sustained research and industry practice, predicting construction labour productivity (CLP) using existing factor and activity modelling approaches remains a challenge. The purpose of this paper is to first demonstrate the limited usefulness of activity models and then to propose a system model approach that integrates factor and activity models for better prediction of CLP.
Design/methodology/approach
The system model parameters – comprising factors and practices – and work sampling proportions (WSPs) were identified from literature. Field data were collected from 11 projects over a span of 29 months. Activity models based on the relationship between CLP and WSPs were created, and their validity was tested using regression analysis for eight activities in the concreting, electrical and shutdown categories. The proposed system model was developed for concreting activity using the key influencing parameters in conjunction with WSPs.
Findings
The results of the regression analysis indicate that WSPs, like direct work, are not significantly correlated to CLP and fail to explain its variance. Evaluation of the system model approach for the concreting activity showed improved CLP prediction as compared to existing approaches.
Research limitations/implications
The system model was tested for concreting activity using data collected from six projects; however, further investigation into the model’s accuracy and efficacy using data collected from other labour-intensive activities is suggested.
Originality/value
This research establishes the role of WSPs in CLP modelling, and develops a system modelling approach to assist researchers and practitioners in the analysis of productivity-influencing parameters together with WSPs.

Abstract
Purpose
There is increasing recognition amongst healthcare providers on the necessity to improve fire safety management in healthcare facilities. This is possibly not yet satisfactory because of recent fire incidents in Asia. This paper set out to analyse the literature because of the paucity of systematic reviews on fire safety management of public healthcare facilities and proffer preventive measures.
Design/methodology/approach
Thirty related studies were identified with the support of the Preferred Reporting Items for Systematic reviews and Meta-Analyses via Scopus and Web of Science databases.
Findings
Influencing factors, hindrances to fire safety management and preventive measures for fire-related occurrence in Asian hospital buildings were the three themes that emerged from the reviewed. The factors that influence fire in Asian hospital buildings were categorised into technical, management and legislation factors.
Research limitations/implications
The recommendations of this paper were based on literature that was systematically reviewed but does not compromise the robustness concerning fire safety management in hospital buildings across Asian countries. Much is needed to be known regarding fire safety in healthcare buildings across Asian countries. This paper recommended exploratory sequential mixed-methods approach as part of the implications for further studies. This will allow in-depth face-to-face interviews and increase the generalisability of future findings concerning fire safety management in hospital buildings across Asian countries to a larger population.
Practical implications
As part of the practical implications, this paper recommends fire safety management plan as one of the practical possible measures for addressing technical, management and legislation factors. Also recommended is training and fire safety education of healthcare staff in collaboration with safety firefighters to address major issues that may arise from management factors. The government should upgrade the safety technology equipment in healthcare facilities as part of measures to mitigate issues concerning technical and legislation factors. Also, the identified factors are part of the theoretical contributions to the advancement of knowledge and this brings to the front burners new opening.
Originality/value
This is probably the first systematic review paper on fire safety hospital buildings in Asia.

Abstract
The construction sector has significantly evolved in recent decades, in parallel with a huge increase in the amount of data generated and exchanged in any construction project. These data need to be managed in order to complete a successful project in terms of quality, cost and schedule in the the context of a safe project environment while appropriately organising many construction documents.
However, the origin of these data is very diverse, mainly due to the sector’s characteristics. Moreover, these data are affected by uncertainty, complexity and diversity due to the imprecise nature of the many factors involved in construction projects. As a result, construction project data are associated with large, irregular and scattered datasets.
The objective of this chapter is to introduce an approach based on a fuzzy multi-dimensional model and on line analytical processing (OLAP) operations in order to manage construction data and support the decision-making process based on previous experiences. On one hand, the proposal allows for the integration of data in a common repository which is accessible to users along the whole project’s life cycle. On the other hand, it allows for the establishment of more flexible structures for representing the data of the main tasks in the construction project management domain. The incorporation of this fuzzy framework allows for the management of imprecision in construction data and provides easy and intuitive access to users so that they can make more reliable decisions.

Abstract
Purpose
This paper investigates the structural model of vector autoregression (SVAR) of the interdependent relationship of inflation, monetary policy and Islamic banking variables (RDEP, RFIN, DEP, FIN) in Indonesia. By using monthly data for the period 2001M01-2019M12, the impulse response function (IRF), forecasting error decomposition variation (FEDV) is used to track the impact of Sharīʿah variables on inflation (prices).
Design/methodology/approach
This research uses quantitative approach with SVAR model to reveal the problem.
Findings
The empirical results of SVAR, the IRF show that policy shocks have a negative impact on all variables in Islamic banking except the equivalent deposit interest rate (RDEP). The impact of both conventional (7DRR) and Sharīʿah (SBIS) policies has a similar pattern. While the transmission of Sharīʿah monetary variables as a policy operational target in influencing inflation is positive. In addition, the FEDV clearly revealed that the variation in the Sharīʿah financial sector was relatively large in monetary policy shocks and their role in influencing prices.
Originality/value
The empirical results of SVAR, the IRF show that policy shocks have a negative impact on all variables in Islamic banking except the equivalent deposit interest rate ‘RDEP’. The impact of both conventional “7DRR” and Sharīʿah “SBIS” policies has a similar pattern. While the transmission of Sharīʿah monetary variables as a policy operational target in influencing inflation is positive. In addition, the FEDV clearly revealed that the variation in the Sharīʿah financial sector was relatively large in monetary policy shocks and their role in influencing prices.
