Abstract
Purpose
Intelligent pneumatic actuator (IPA) is a new generation of actuator developed for Research and Development (R&D) purposes in the academic and industrial fields. The purpose of this paper is to show the application of optical encoder and pressure sensor in IPA, to develop a real-time model similar to the existing devices, and to assess the position control performance using a proportional-integrative (PI) controller and a bang-bang controller in real-time.
Design/methodology/approach
A micro optical encoder chip is used to detect cylinder rod position by reading constructed laser stripes on a guide rod, whereas a pressure sensor is used to detect the chamber pressure reading. To control the cylinder movements by manipulating pulse-width modulation (PWM) cycles, two unit valves of two ports and two positions were used. A PI controller and a bang-bang controller are used with suitable gain value to drive the valve using PWM to achieve the target actuator position.
Findings
The results show the experimental results of the closed-loop position tracking performance of the system using a data acquisition (DAQ) card over MATLAB software.
Originality/value
This paper presents a real-time model used to replace the microcontroller-based system from previous IPA design. The paper proposes two control strategies, PI and bang-bang, to control position using encoder and pressure reading.

Abstract
Purpose
Learning from past construction accident reports is critical to reducing their occurrence. Digital technology provides feasibility for extracting risk factors from unstructured reports, but there are few related studies, and there is a limitation that textual contextual information cannot be considered during extraction, which tends to miss some important factors. Meanwhile, further analysis, assessment and control for the extracted factors are lacking. This paper aims to explore an integrated model that combines the advantages of multiple digital technologies to effectively solve the above problems.
Design/methodology/approach
A total of 1000 construction accident reports from Chinese government websites were used as the dataset of this paper. After text pre-processing, the risk factors related to accident causes were extracted using KeyBERT, and the accident texts were encoded into structured data. Tree-augmented naive (TAN) Bayes was used to learn the data and construct a visualized risk analysis network for construction accidents.
Findings
The use of KeyBERT successfully considered the textual contextual information, prompting the extracted risk factors to be more complete. The integrated TAN successfully further explored construction risk factors from multiple perspectives, including the identification of key risk factors, the coupling analysis of risk factors and the troubleshooting method of accident risk source. The area under curve (AUC) value of the model reaches up to 0.938 after 10-fold cross-validation, indicating good performance.
Originality/value
This paper presents a new machine-assisted integrated model for accident report mining and risk factor analysis, and the research findings can provide theoretical and practical support for accident safety management.

Abstract
Purpose
This study aims to examine the understudied topic of Islamic entrepreneurship by adapting the framework of waqf-based entrepreneurship to identify the crucial factors driving waqf-based entrepreneurs’ motivation.
Design/methodology/approach
A partial least squares structural equation model was used to validate the hypotheses, and in-depth interviews were conducted to gain deeper insights into the findings.
Findings
The key findings revealed that self-commitment, entrepreneurial skills and family support exert a significant and positive influence on waqfpreneurs’ motivation to engage in waqf-based entrepreneurship, with self-commitment playing a mediating role between self-actualisation and waqfpreneurial motivation. Additionally, the study proposes categorisations of waqfpreneurs based on the volume of waqf funds managed; their capacity to execute waqf-based entrepreneurship; and institutional performance metrics.
Research limitations/implications
The limited sample size restricts the generalisability of the study. Future research should use a larger sample to generate more broadly applicable results. In addition, the methodology can be replicated in other countries to identify new factors influencing waqfpreneurs’ motivation or to uncover aspects not explored in this research. Future studies could also use qualitative methodologies such as grounded theory, ethnography or case studies. This would allow for a deeper exploration of motivational factors not yet captured, directly from the lived experiences of waqfpreneurs/nazhirs.
Practical implications
The study provides evidence of the key factors that influence waqf-based entrepreneurship, contributing to the literature on entrepreneurship and waqf. It also offers valuable insights for the government and other stakeholders into strategies to motivate waqf-based entrepreneurs, ultimately fostering the development of waqf assets, value creation and sustainable waqf benefit distribution.
Originality/value
The study aims to address the lack of research on Islamic entrepreneurship by specifically modifying the framework of waqf-based entrepreneurship to investigate the key factors that influence individuals’ motivation to conduct waqf-based entrepreneurship and management activities.

Abstract
Purpose
This study aims to investigate what past scholars have learned about Muslim consumer compliance behaviour in Islamic banks and identify what future research is needed. In addition, it also explores the relationship model between the previously studied determining factors and the customer’s Sharia compliance behaviour.
Design/methodology/approach
This study used a bibliometric–systematic literature review analysis using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) technique by reviewing the articles published from 2013 to 2023. The PRISMA procedures involved several stages, including identification, screening, eligibility, analysis and conclusion based on the findings.
Findings
The results found that customer Sharia compliance behaviour determinants in Islamic banks are attitude, subjective norms, perceived behavioural control, Islamic financial literacy, religiosity, consumer conformity, Islamic branding and behavioural intention. Interestingly, the results indicated that such factors as consumer conformity, Islamic branding and sustainable intentions are less discussed.
Practical implications
Decision-makers in Islamic banks must use digital technology to offer better service and make operations more reachable for customers to access information, complete transactions and manage their accounts by Sharia principles. Therefore, the bank needs to continually produce innovative products and services so that customers have a greater variety of options to suit their Sharia-compliant financial needs. Theoretically, this study has contributed by finding the main critical domains influencing customers’ Sharia compliance behaviour, such as attitudes, subjective norms, perceptions of behavioural control, knowledge of Islamic finance, religiosity, consumer conformity, Islamic branding and behavioural intentions. Then, it makes a theoretical contribution by establishing a model that explains how customers make decisions based on Sharia-related factors in the context of their purchases.
Originality/value
Past studies focused on the Sharia compliance behaviour in paying Zakat for takaful customers. Therefore, this study provides critical factors of Sharia compliance behaviour on conformity, Islamic branding and sustainable intention regarding unexplored consensus on the determinants and outcomes of customer Sharia compliance behaviour of Islamic banking.

Abstract
Purpose
This study aims to explore the family experiences of delinquent adolescents and uses a descriptive phenomenological research design.
Design/methodology/approach
The study explores the family experiences of delinquent adolescents and uses a descriptive phenomenological research design. Eight adolescents that were under detainment in a rehabilitation centre in Malaysia participated in the study. Data were gathered through semi-structured interviews and reflective journals.
Findings
Five themes common to the participants’ experience were inductively identified from the analysis. These were: life without guidance, alienation and isolation, conflict on how the family is managed; I am still a little child and prisoners at home.
Originality/value
Despite many studies on delinquent adolescents were conducted in Malaysia, no study has been conducted so far to explore and understand the experience of female adolescents in their families.

Abstract
Purpose
The objective of this study is to explore the effects of financial literacy level and risk aversion on the saving behavior. The literature review showed dialectical results. Therefore, this study attempts to clarify the debatable of these results by studying the mediating effect of risk aversion on the relationships between demographics determinants and saving behavior moderated by the effect of the financial literacy level.
Design/methodology/approach
The data were collected from the University of Normandy; the study sample included 516 respondents representing different segments of French households. The structural equation analysis was utilized to control the impact of financial literacy as a moderate variable and the risk aversion as a mediator variable among the link between sociodemographic factors and saving behavior.
Findings
The results demonstrated that there were significant effects of demographics factors on risk aversion. Moreover, financial literacy moderates the relationships between risk aversion and saving behavior.
Research limitations/implications
The major limitation of this research is the small size of the study sample. This paper is restricted to French households. Future financial education training should cover the European context.
Practical implications
This study provides further evidence that financial literacy should be considered an important factor for improving household well-being. The paper encourages governments and financial institutions to create a national financial education program.
Originality/value
This paper is the first attempt to employ a sample of low-income households after financial education training in the French context.

Abstract
Purpose
International construction joint ventures (ICJVs) will fully realize their potential for success and effectively monitor performance when an adequate and suitable performance benchmark is established. However, existing studies fall short of adequately providing a mutually acceptable benchmark for assessing the performance of ICJVs. This study aims to develop an adequate and suitable performance measurement framework for ICJVs.
Design/methodology/approach
A twofold structured questionnaire survey, supplemented by semi-structured interviews, was used to collect data from the practitioners of ICJVs hosted in the developing country of Ghana. The data were analyzed by using descriptive statistics, confirmatory factor analysis (CFA) and a hybrid-fuzzy logic approach.
Findings
A list of 30 performance indicators (PIs), defined by project performance, perceived satisfaction, company/partner performance, socio-environmental performance and performance of ICJV management, was validated and proved to be significant. Only 22 out of the 30 PIs, focusing on project efficiency, societal improvement and organizational goals are realized by the ICJV practitioners. Further, suitable determinants and viable quantitative ranges for measuring each PI are established to prevent different interpretations of the meanings of PIs and objectively express the level of success in quantitative terms. The results call for further investigation of the convergence between the practice of and research into some PIs (e.g. socio-environmental performance) and a range of different performance levels (PLs) in a more scientific manner.
Practical implications
This study not only advances the knowledge base and practice of performance measurement in ICJVs but could also assist stakeholders and decision-makers to assess, compare and monitor the performance of different ICJV projects on common grounds objectively.
Originality/value
This study not only comprehensively assessed PIs – what to measure – but also systematically determined suitable determinants – how to measure – for each PI.
