Abstract
Purpose
Monitoring of the quality of precast concrete (PC) components is crucial for the success of prefabricated construction projects. Currently, quality monitoring of PC components during the construction phase is predominantly done manually, resulting in low efficiency and hindering the progress of intelligent construction. This paper presents an intelligent inspection method for assessing the appearance quality of PC components, utilizing an enhanced you look only once (YOLO) model and multi-source data. The aim of this research is to achieve automated management of the appearance quality of precast components in the prefabricated construction process through digital means.
Design/methodology/approach
The paper begins by establishing an improved YOLO model and an image dataset for evaluating appearance quality. Through object detection in the images, a preliminary and efficient assessment of the precast components' appearance quality is achieved. Moreover, the detection results are mapped onto the point cloud for high-precision quality inspection. In the case of precast components with quality defects, precise quality inspection is conducted by combining the three-dimensional model data obtained from forward design conversion with the captured point cloud data through registration. Additionally, the paper proposes a framework for an automated inspection platform dedicated to assessing appearance quality in prefabricated buildings, encompassing the platform's hardware network.
Findings
The improved YOLO model achieved a best mean average precision of 85.02% on the VOC2007 dataset, surpassing the performance of most similar models. After targeted training, the model exhibits excellent recognition capabilities for the four common appearance quality defects. When mapped onto the point cloud, the accuracy of quality inspection based on point cloud data and forward design is within 0.1 mm. The appearance quality inspection platform enables feedback and optimization of quality issues.
Originality/value
The proposed method in this study enables high-precision, visualized and automated detection of the appearance quality of PC components. It effectively meets the demand for quality inspection of precast components on construction sites of prefabricated buildings, providing technological support for the development of intelligent construction. The design of the appearance quality inspection platform's logic and framework facilitates the integration of the method, laying the foundation for efficient quality management in the future.

Abstract
Purpose
Quality 4.0 is essential to the Industry 4.0 framework, notably in the electronics sector. It evaluates product quality in real-time using automatic process controls, quality tools and procedures. The implementation of Quality 4.0 criteria in the electronics industry is the subject of this study’s investigation and analysis. In this study, nine Customer Requirements (CRs) and 18 Design Requirements (DRs) have been defined to adopt Quality 4.0, aiming to increase yield while reducing defects. This study has developed a Quality 4.0 framework for effective implementation, incorporating the People, Process and Technology categories.
Design/methodology/approach
Many CRs and DRs of Quality 4.0 exhibit interdependencies. The Analytic Network Process (ANP) considers interdependencies among the criteria at various levels. Quality Function Deployment (QFD) can capture the customer’s voice, which is particularly important in Quality 4.0. Therefore, in this research, we use an integrated ANP-QFD methodology for prioritizing DRs based on the customers' needs and preferences, ultimately leading to better product and service development.
Findings
According to the research findings, the most critical consumer criteria for Quality 4.0 in the electronics sector are automatic systems, connectivity, compliance and leadership. The Intelligent Internet of Things (IIOTs) has emerged as the most significant design requirement that enables effective control in production. It is observed that robotics process automation and a workforce aligned with Quality 4.0 also play crucial roles.
Originality/value
Existing literature does not include studies on identifying CRs and DRs for implementing Quality 4.0 in the electronics industry. To address this gap, we propose a framework to integrate real-time quality measures into the Industry 4.0 context, thereby facilitating the implementation of Quality 4.0 in the electronics industry. This study can provide valuable insights for industry practitioners to implement Quality 4.0 effectively in their organizations.

Abstract
Purpose
The purpose of this study is to assess the implications of auditor–client geographic proximity on audit fees, audit report lag and audit quality in the context of an emerging economy, Bangladesh.
Design/methodology/approach
The auditor–client proximity is gauged in kilometers and travel time, consistent with prior research to assess its association with audit fees, audit report lag and audit quality. Analyzing a data set of 469 firm-year observations from 2018 to 2021 through panel regression, the results are then interpreted in accordance with cluster theory and transaction cost theory.
Findings
The findings affirm a significant positive association of auditor–client proximity with audit fees and audit report lag. Distant auditors charge lower fees and maintain the timeliness of audit reports to capture and retain distant clients. In addition, the study uncovers a negative association between proximity and audit quality. Geographic proximity can create a familiarity threat between the management team of the client and the local auditor, which can decrease audit quality. These associations are more pronounced in low-risk clients than the high-risk ones.
Practical implications
These findings underscore the intricate interplay between geographic proximity, communication hurdles and their effects on diverse facets of the audit process that both auditor and client should consider in future audit engagement.
Originality/value
This research criticizes the existing literature linking auditor–client proximity with audit quality, fees and report lags and provides novel insight from an emerging economy context.

Abstract
Purpose
The purpose of this study is to examine the effect of audit committee (AC) tenure on corporate governance, a topic that has been long debated. Social capital theory explains how directors’ effectiveness varies through tenure. Consistent with this theory, this paper argues that AC tenure has an inverted U-shaped relationship with AC governance.
Design/methodology/approach
This paper estimates a quadratic function that regresses constructs for AC governance on the average AC, the AC chair, and nonchair tenure, and their respective square terms. The constructs for AC governance include financial reporting quality measures and perceived auditor independence measures.
Findings
This paper finds that average AC, AC chair, and nonchair tenure have inverted U-shaped relationships with financial reporting quality, consistent with social capital theory. This paper also finds similar associations when examining perceived auditor independence. The results are generally consistent with AC directors accumulating knowledge and social capital, which improves AC governance to an optimal level, following which entrenchment and familiarity occur and AC governance declines.
Originality/value
To the best of the authors’ knowledge, this is the first study in AC governance literature to show a nonlinear relationship between AC tenure and AC governance. This paper extends Huang and Hilary (2018) by demonstrating that a nonlinear effect is also present in the AC, a key board committee responsible for monitoring financial reporting quality and appointing auditors and approving their services. This paper further documents that the AC subsumes the effect of the overall board in some areas of AC oversight, and reconciles the inconclusive findings of prior research by showing a nonlinear relationship between AC tenure and AC governance.

Abstract
Purpose
Industry 4.0 is based on cyber-physical systems (CPSs); therefore, the risks of cyberattacks tend to increase. A cyberattack is any malicious act that could jeopardize the security of production, accounting and financial systems. This review hypothesizes quality management is in a position to play an important role in preventing and detecting hacker attacks.
Design/methodology/approach
To verify this hypothesis, Lakato’s research program was utilized in a bibliometric review. This review was separated into two stages: the first was a descriptive analysis and the second was a scientific mapping, done using a technique known as text mining. This technique was guided by factorial and cluster analysis.
Findings
The analysis revealed that this subject is emerging and relevant. It was observed that understanding the vulnerabilities of connected systems is crucial for combating cyberattacks. Furthermore, the study highlighted the potential of multivariate control charts, such as Hotelling’s T-squared charts and Exponentially Weighted Moving Average (EWMA) control charts, in efficiently detecting anomalies in connected systems.
Originality/value
This article introduces an approach integrating quality management, statistical analysis and cybersecurity to safeguard CPSs. By leveraging advanced statistical techniques, such as Hotelling T2 charts and EWMA charts, in conjunction with the foundational principles of quality management systems (QMS), such as continuous improvement and process standardization, this could be a potentially robust defense against cyberattacks. The integration of these tools allows for the early detection of anomalies and potential cyber threats, ensuring the prevention of integrity and security of interconnected industrial processes.

Abstract
Purpose
Social media data contains a wealth of content related to customers’ reactions to, and comments on, firms’ performance. Through the lens of signaling theory, this paper aims to investigate the use of social media data as a knowledge resource in communicating firms’ noncompliance risk to regulatory agencies.
Design/methodology/approach
This paper proposes a two-step social media analytics framework to detect noncompliant firms. First, it creates a context-specific dictionary that contains keywords relevant to firms’ noncompliant behaviors. Next, it extracts those keywords from customer reviews, customer sentiment and emotions to predict firm noncompliance. It tests these ideas in the context of food safety regulations.
Findings
It identified over 100 words that are related to restaurants’ hygiene deficiencies. Using the occurrence of these words in customer reviews, as well as sentiments and emotions expressed within them, the author’s best-performing model can identify nearly 90% of the restaurants that severely violated regulations.
Practical implications
After being processed by appropriate machine learning algorithms, customer reviews serve as valuable knowledge resources, enabling regulatory agencies to identify noncompliant firms. Regulatory agencies can use this model to complement the current compliance monitoring scheme.
Originality/value
This research contributes a novel methodology for creating a context-specific dictionary that keeps only the relevant words customers use when discussing firms’ noncompliant acts. In the absence of such an approach, numerous irrelevant signals would be included in the modeling process, thereby increasing the cost of social media analytics.
