Abstract
Purpose
The COVID-19 situation affected the whole landscape of retailing in India and around the world. However, some businesses have used the pandemic-related difficulties into opportunities. E-tailing is one of the ways that helped people in India to continue shopping their essential products and choosing their luxury products without making any physical visits during the lockdown. This research understands the current situation through an observation study and suggests the e-tailing model suitable during the COVID-19 and beyond.
Design/methodology
We used secondary data to make the observational study. We also conducted two case studies and interviews with grocery shops and an automotive company.
Findings
This research suggests a simple collaborative e-tailing model combining all supply chain players to reduce people’s movement, timely delivery and enhanced service to meet customers demand during the lockdown period.
Originality/value
This paper has considered two real cases for discussion and also obtained information from public domain. The proposed model has been discussed with the case companies, and it hoped to support business planning for online services.

Abstract
Purpose
This paper aims to empirically investigate time–frequency linkages between Euramerican mature and Asian emerging crude oil futures markets in terms of correlation and risk spillovers.
Design/methodology/approach
With daily data, the authors first undertake the MODWT method to decompose yield series into four different timescales, and then use the R-Vine Copula-CoVaR to analyze correlation and risk spillovers between Euramerican mature and Asian emerging crude oil futures markets.
Findings
The empirical results are as follows: (a) short-term trading is the primary driver of price volatility in crude oil futures markets. (b) The crude oil futures markets exhibit certain regional aggregation characteristics, with the Indian crude oil futures market playing an important role in connecting Euramerican mature and Asian emerging crude oil futures markets. What’s more, Oman crude oil serves as a bridge to link Asian emerging crude oil futures markets. (c) There are significant tail correlations among different futures markets, making them susceptible to “same fall but different rise” scenarios. The volatility behavior of the Indian and Euramerican markets is highly correlated in extreme incidents. (d) Those markets exhibit asymmetric bidirectional risk spillovers. Specifically, the Euramerican mature crude oil futures markets demonstrate significant risk spillovers in the extreme short term, with a relatively larger spillover effect observed on the Indian crude oil futures market. Compared with India and Japan in Asian emerging crude oil futures markets, China's crude oil futures market places more emphasis on changes in market fundamentals and prefers to hold long-term positions rather than short-term technical factors.
Originality/value
The MODWT model is utilized to capture the multiscale coordinated motion characteristics of the data in the time–frequency perspective. What’s more, compared to traditional methods, the R-Vine Copula model exhibits greater flexibility and higher measurement accuracy, enabling it to more accurately capture correlation structures among multiple markets. The proposed methodology can provide evidence for whether crude oil futures markets exhibit integration characteristics and can deepen our understanding of connections among crude oil futures prices.

Abstract
Purpose
The rock drill’s drill tail experiences high-frequency fretting simultaneously in the rotational and axial directions. Due to the complex working characteristics and the low viscosity of the water medium, the pure water seal is susceptible to damage and failure. The purpose of this paper is to enhance the water seal’s performance.
Design/methodology/approach
The Y-shaped seal ring is modeled and simulated using orthogonal testing. Through analysis of the impact of various seal section parameters on sealing performance, the maximum contact stress and maximum Von Mises stress are selected as indicators of sealing effectiveness.
Findings
The maximum contact stress is proportional to lip thickness and chamfer length but inversely proportional to lip length. Meanwhile, the maximum Von Mises stress is directly influenced by lip depth and the included angle of the lip and drill tail but is inversely proportional to the lip thickness. The enhanced Y-shaped water seal sees reductions of 15% and 45% in maximum contact stress and maximum Von Mises stress, respectively.
Originality/value
This paper used analytical method and model that is helpful for design of the water seal’s structure in complex working characteristics and the low viscosity of the water medium.

Abstract
Purpose
This study aims to learn the dynamic radar cross-section (RCS) of a deflection air brake.
Design/methodology/approach
The aircraft model with delta wing, V-shaped tail and blended wing body is designed, and high-precision unstructured grid technology is used to deal with the surface of air brake and fuselage. The calculation method based on multiple tracking and dynamic scattering is presented to calculate RCS.
Findings
The fuselage has a low scattering level, and the opening air brake will bring obvious dynamic RCS effects to itself and the whole machine. The average indicator of air brake RCS can be lower than –0.6 dBm2 under the tail azimuth, while that of forward and lateral direction is lower. The mean RCS of fuselage is obviously higher than that of air brake, while the deflected air brake and its cabin can still provide strong scattering sources at some azimuths. When the air brake is opening, the change amplitude of the aircraft forward RCS can exceed 19.81 dBm2.
Practical implications
This research has practical significance for the dynamic electromagnetic scattering analysis and stealth design of the air brake.
Originality/value
The calculation method for aircraft RCS considering air brake dynamic deflection has been established.

Abstract
Purpose
This study aims to investigate disclosure of asbestos-related liabilities in corporate accounts and counter-accounts to examine whether and how accounting contributes to corporate accountability for asbestos-contaminated products.
Design/methodology/approach
This study uses the Goffmanesque perspective on impression management to examine instances of concealed asbestos-related liabilities in corporate accounts vis-à-vis the revealing of such liabilities in counter-accounts.
Findings
The findings show counter-accounts provide significant information on liabilities originating from the exposure of employees and consumers to asbestos. By contrast, the malleability of accounting tools enables companies to eschew accounting disclosures. While the frontstage positive performance of companies served an impression management role, their backstage concealing actions enabled companies to cover up asbestos-related liabilities. These companies used three categories of mechanisms to avoid disclosure of asbestos-related liabilities: concealing via a “cloak of competence”, impression management via epistemic work and a silent strategy of concealment frontstage with strategic reorganisation backstage.
Practical implications
This study has policy relevance as regulators need to consider the limits of corporate disclosures as an accountability tool. The findings may also initiate academic and practitioner conversations about accounting standards for long-term liabilities.
Originality/value
This study highlights the strategies companies use both frontstage and backstage to avoid disclosing asbestos-related liabilities. Through analysis of accounts and counter-accounts, this study identifies the limits of accounting as an accountability tool regarding asbestos-induced diseases and deaths.

This research paper aims to investigate the effects of internal audit’s (IA) use of data analytics and the performance of consulting activities on perceived IA quality.
Abstract
Purpose
This research paper aims to investigate the effects of internal audit’s (IA) use of data analytics and the performance of consulting activities on perceived IA quality.
Design/methodology/approach
The authors conduct a 2 × 2 between-subjects experiment among upper and middle managers where the use of data analytics and the performance of consulting activities by internal auditors are manipulated.
Findings
Results highlight the importance of internal auditor use of data analytics and performance of consulting activities to improve perceived IA quality. First, managers perceive internal auditors as more competent when the auditors use data analytics. Second, managers perceive internal auditors’ recommendations as more relevant when the auditors perform consulting activities. Finally, managers perceive an improvement in the quality of relationships with internal auditors when auditors perform consulting activities, which is strengthened when internal auditors combine the use of data analytics and the performance of consulting activities.
Research limitations/implications
From a theoretical perspective, this research builds on the IA quality framework by considering digitalization as a contextual factor. This research focused on the perceptions of one major stakeholder of the IA function: senior management. Future research should investigate the perceptions of other stakeholders and other contextual factors.
Practical implications
This research suggests that internal auditors should prioritize the development of the consulting role in their function and develop their digital expertise, especially expertise in data analytics, to improve perceived IA quality.
Originality/value
This research tests the impacts of the use of data analytics and the performance of consulting activities on perceived IA quality holistically, by testing Trotman and Duncan’s (2018) framework using an experiment.

Abstract
Purpose
This paper examines the impact of sharia-compliant debt financing on stock price crash risk. Unlike those previous studies that took Sukuk or sharia-compliant firms, this study tests the impact of the proportion reported sharia-compliant debt financing in the balance sheet on the risk of price crash of a firm.
Design/methodology/approach
Using the data from 2,752 firm-year observations of 344 Malaysian non-financial listed companies from 2012 to 2019, this article used a robust panel data estimation technique for statistical inferences. This study also employs panel GMM and quantile least squares as the robustness check.
Findings
This study established a negative relationship between sharia-compliant debt financing and stock price crash risk. The robustness checks with different estimation techniques confirm the results. It implies that firms with a more significant proportion of Sharia-compliant financing tend to have lower future stock price crash risk.
Practical implications
Consistent with the Islamic finance literature, the present study contributes to the existing literature on Islamic capital markets from the perspective of stock price crash risk because it is vital for risk management and investment decision-making as a measure of tail risk for stocks. The findings of this research will assist investors in developing portfolio strategies that incorporate firms with higher levels of sharia-compliant debt financing in their balance sheets. Additionally, the results of this study suggest that policymakers and regulatory bodies should consider revising their monitoring approaches for publicly listed firms.
Originality/value
This study is interesting and unique, as it is a pioneer in testing the impact of sharia-compliant debt financing on reducing stock price crash risk.

Abstract
Purpose
The priority of this study is to contribute to the literature by examining herding behavior at different periods of the COVID-19 pandemic. Furthermore, this study aims to investigate the herding behavior conditioned on market liquidity and information demand.
Design/methodology/approach
This study investigates herding behavior in Vietnam's stock exchanges (Ha Noi Stock Exchange and Ho Chi Minh Stock Exchange) on a sample of daily stock closing prices of 425 firms from 2018 to the first half of 2022.
Findings
The research confirms the existence of herding behavior not only for the whole but also during and post-COVID periods. These results are robust in both bull and bear markets, further confirming the influence of COVID-19 on herding in Vietnamese background. Moreover, when the authors condition exogenous factors for each period, the herding tendency is more evident at the medium market liquidity level than at high and low levels. Besides, the pandemic causes herding behavior of investors with low and medium information demand.
Research limitations/implications
These findings imply some recommendations that facilitate investors, policymakers and researchers in the context of the COVID-19 crisis.
Originality/value
The study contributes to the herding literature by examining herd behavior during the post-COVID period, suggesting the long-term impact of the health crisis. Furthermore, the research provides new evidence of herding behavior conditioned on market liquidity and information demand during different COVID sub-periods.

Abstract
Purpose
This study aims to examine the implementation of International Financial Reporting Standards (IFRS) in Saudi Arabia. It investigates how the adoption of IFRS has affected four critical areas in the financial statements of publicly listed companies: profit and loss statement, balance sheet, cash flow statement and retained equity statement in Saudi Arabia. The paper also explores the essential factors/drivers that influence the adoption of IFRS and its implication in Saudi Arabia.
Design/methodology/approach
Data was obtained from Saudi Stock Exchange (Tadawul) listed companies from eleven industries in Saudi Arabia. This cross-sectional study analyses critical financial data across eleven distinctive industries. To identify the impact of adopting IFRS, the researchers use a paired t-test to evaluate seven key elements of financial statements underlying the critical areas: non-current asset, current asset, total assets, shareholders equity, non-current liability, current liability and total liability. The sample captures cross-sectional data from well-developed global industries in Saudi Arabia, pre- and post-implementation of IFRS. Thus, the analysis of the sample data gives a representative picture of the population of the Saudi Arabian industry.
Findings
The results reveal significant differences between GAAP and IFRS reporting standards in the measurement, recognition and classification of non-current assets and liabilities. The differences are expressed in the variance between the GAAP and IFRS. Specifically, the differences between GAAP and IFRS demonstrated by the t-value are significant and reliable (respectively, 5.3 and 4.1). Additionally, the t-value is validated by the p-value, which in both was significant.
Research limitations/implications
The outcomes of this research will benefit accounting information users, practitioners, researchers and regulators. Since Saudi Arabia’s policymakers have mandated the full adoption of IFRS in financial reporting, the study contributes to the adoption of IFRS practices throughout the Saudi industry. Adopting full IFRS standards requires widespread IFRS expertise to cope with the transition.
Originality/value
This study advances research into the perennial issues associated with changes in reporting towards IFRS standards, especially in Saudi Arabia. The contribution to theory and practice enters new and fruitful areas.

This preliminary investigation aims to examine the psychological impact of the COVID-19 pandemic on patients and staff within a high secure service.
Abstract
Purpose
This preliminary investigation aims to examine the psychological impact of the COVID-19 pandemic on patients and staff within a high secure service.
Design/methodology/approach
To discern the connection between COVID-19-related distress and multiple factors, the study involved 31 patients and 34 staff who completed assessments evaluating coping strategies, resilience, emotional reactivity, ward atmosphere and work-related aspects.
Findings
Results demonstrated that around a third of staff (31.2%) experienced COVID-19-related distress levels that met the clinical cut-off for possible post-traumatic stress disorder. Emotional reactivity, staff shortages, secondary traumatic stress and coping strategies were all positively correlated with COVID-19-related-distress. Resilience was negatively associated with distress, thus acting as a potential mitigating factor. In comparison, the prevalence of distress among patients was low (3.2%).
Practical implications
The authors postulate that increased staff burdens during the pandemic may have led to long-term distress, while their efforts to maintain minimal service disruption potentially shielded patients from psychological impacts, possibly lead to staff “problem-focused coping burnout”. This highlights the need for in-depth research on the enduring impacts of pandemics, focusing on mechanisms that intensify or alleviate distress. Future studies should focus on identifying effective coping strategies for crisis situations, such as staff shortages, and strategies for post-crisis staff support.
Originality/value
The authors postulate that the added burdens on staff during the pandemic might have contributed to their distress. Nonetheless, staff might have inadvertently safeguarded patients from the pandemic’s psychological ramifications by providing a “service of little disruption”, potentially leading to “problem-focused coping burnout”. These findings underscore the imperative for further research capturing the enduring impacts of pandemics, particularly scrutinising factors that illuminate the mechanisms through which distress is either intensified or alleviated across different groups. An avenue worth exploring is identifying effective coping styles for pandemics.
