Abstract
Purpose
The high-pressure accumulator has been widely used in the hydraulic system. Failure pressure prediction is crucial for the safe design and integrity assessment of the accumulators. The purpose of this study is to accurately predict the burst pressure and location for the accumulator shells due to internal pressure.
Design/methodology/approach
This study concentrates the non-linear finite element simulation procedure, which allows determination of the burst pressure and crack location using extensive plastic straining criterion. Meanwhile, the full-scale hydraulic burst test and the analytical solution are conducted for comparative analysis.
Findings
A good agreement between predicted and measured the burst pressure that was obtained, and the predicted failure point coincided very well with the fracture location of the actual shell very well. Meanwhile, the burst pressure of the shells increases with wall thickness, independent of the length. It can be said that the non-linear finite element method can be employed to predict the failure behavior of a cylindrical shell with sufficient accuracy.
Originality/value
This paper can provide a designer with additional insight into how the pressurized hollow cylinder might fail, and the failure pressure has been predicted accurately with a minimum error below 1%, comparing the numerical results with experimental data.

This study aims to investigates the challenges faced by Pakistani financial institutes (FIs) and regulators in implementing robust customer due diligence measures.
Abstract
Purpose
This study aims to investigates the challenges faced by Pakistani financial institutes (FIs) and regulators in implementing robust customer due diligence measures.
Design/methodology/approach
The study adopted a qualitative technique. Twenty-five semi-structured interviews with chief compliance officers and regulators were conducted.
Findings
The study concluded that the main challenges are name screening, obsolete nature and quality of databases and undocumented, unregistered and unregulated portions of the economy and society. In addition, identification and verification of high-profile customers and beneficial owners, lack of specialised staff and cost of compliance are the significant challenges faced by FIs in Pakistan.
Originality/value
The Pakistani financial sector is less researched on anti-money laundering front, especially concerning customer due diligence. Further, the social, cultural and economic norms of the Indian sub-continent are more or less the same. Therefore, the study findings could be generalised to the region.

Abstract
Purpose
Corporate social responsibility (CSR) decoupling indicates a misalignment between how firms report CSR and what firms actually practice with respect to CSR. The purpose of this paper is to examine the relationship between CSR decoupling and financial performance and the factors affecting this relationship.
Design/methodology/approach
This paper collects and combines secondary panel data from multiple sources of Chinese listed firms from 2008 to 2020 to test the direct impact of CSR decoupling on firms’ financial performance and the moderating role of customer structure and operational slack.
Findings
This paper finds that CSR decoupling is negatively associated with firms’ financial performance. These findings further suggest that the negative relationship can be suppressed by customer stability and operational slack, but amplified by customer concentration. These conclusions remain robust to alternate measures of independent and dependent variables and narrower samples.
Originality/value
In the literature, the effect of CSR on firms’ financial performance is inconclusive. This is the first study to examine the impact of CSR decoupling on firms’ financial performance and the factors affecting this relationship. This paper contributes to the CSR decoupling literature from an operations and supply chain management perspective.

Abstract
Purpose
Construction research comprises quality contributions to the modern methods of construction (MMC) context in terms of their benefits and relative advantages. However, the uptake of MMC is yet deemed very low in the public sector. Knowing that public clients acquire the purchasing power and the influential status to drive industry change, understanding their low MMC uptake is necessary.
Design/methodology/approach
A systematic review of literature has been chosen to extract the key variables contributing to the limited adoption of MMC across the public sector, reinforced by a qualitative semi-structured interview with 12 industry leaders and public clients. This methodology enables the authors to explore works from the past decade, paving a direction for an adequate empirical investigation by reviewing and critically analysing 49 academic articles and interviewing 12 industry leaders and public clients.
Findings
The study captured and argued the characteristics that have an influence on public clients' decision, inhibiting the extraction of values associated with greater MMC deployment. A critical analysis resulted in identifying 13 characteristics under 4 main themes, providing a new argument to existing knowledge by calling on the need to better understand public clients and the influence of their own characteristics on their MMC uptake.
Originality/value
This paper utilises the diffusion of innovation (DOI) theory which offers constructs that help explain the influence of the characteristics of a decision-making unit. The authors’ knowledge on public construction clients is limited, and more research in this direction may help in better aggregating construction demand. Overall, arguments provided in this paper enable relative improvements in supply's business models when approaching the public market. The study is believed to be in support of the relative governmental efforts to shape effective policies that can enhance innovation uptake among public bodies.

Abstract
Purpose
While digitalisation requires facilities management (FM) organisations to change at an increasing rate, little is known about the mechanisms that create ownership and enable individuals to implement changes in everyday FM practice. In this study, these mechanisms are explored from a stewardship perspective. The purpose of this paper is to provide insights into the dynamics of organisational change in FM by analysing how stewardship behaviour leads to change.
Design/methodology/approach
A process model for implementing organisational change is constructed, based on existing theoretical insights from stewardship and intrapreneurship literature. The model is evaluated in a case study through analysis of critical events. Interviewing was the key data collection method.
Findings
The process model gives an event-driven explanation of change through psychological ownership. Analysis of multiple critical events suggests that the model explains intra-organisational as well as inter-organisational change. The case data further suggests that, compared with intra-organisational change, tailored relational and motivational support is more important for inter-organisational change because of the higher risks involved. Job crafting emerged as an unanticipated finding that offers interesting prospects for future FM research.
Practical implications
The process model offers guidance for leaders in FM organisations on providing tailored support to internal and external employees during periods of organisational change.
Originality/value
Stewardship and intrapreneurship are combined to provide insights on organisational change in FM. The study demonstrates how intrapreneurial behaviour and stewardship behaviour can be linked to create innovation within and between organisations.
