Abstract
Purpose
This study draws on the upper echelon perspective and effectuation theory to put insights on the relationship between sustainable leadership and sustainable performance.
Design/methodology/approach
The study had adopted the cluster-sampling approach to collect data from 500 small and medium enterprises (SMEs) established in China and India with 46.60% response rate. The SmartPLS 3.0 was employed for data analysis.
Findings
This study verified the mediating role of frugal innovation in emerging markets. Both market and technological turbulence significantly moderated the sustainable leadership-frugal innovation relationship. Nevertheless, the effect of sustainable leadership on frugal innovation did not vary for the different values of entrepreneurial bricolage.
Originality/value
This article contributes by revealing the moderating effect of market and technological turbulence as moderator. Greater market and technological turbulence led to greater impact of sustainable leadership practices on frugal innovation.

Abstract
Purpose
With the growing pressure to gain optimum level of quality and speed, Lean Six Sigma (LSS) practices have drawn considerable attention as a viable alternative for process improvement. However, previous studies revealed that there is very little systematic and rigorous research to validate the claims. In this regard, this paper aims to empirically examine the effect of LSS practices on quality performance in the medical device manufacturing industry.
Design/methodology/approach
For this study, partial least square–based structural equation modeling (PLS-SEM) was used to empirically examine the effect of LSS practices on quality performance in Malaysian medical device manufacturing industry.
Findings
The findings of this paper revealed that LSS practices have a significant and positive effect on quality performance in the medical device manufacturing industry.
Practical implications
This paper will serve as a valuable implication for industry practitioners in providing them with a clearer managerial direction to exploit the strength of LSS practices to achieve company’s quality goals. Moreover, this study will serve as a basis for future LSS scholars, providing them with valuable insights and directions for future research.
Originality/value
This paper develops a conceptual LSS framework that captures the integrated nature of two methodologies and provides empirical evidence that supports the positive influence of LSS practices on quality performance; hence, it contributes to the growing body of LSS literature in both theoretical and empirical sense.

Abstract
Purpose
This paper aims to investigate the relation between audit firms’ switch to limited liability partnership (LLP) from limited liability company (LLC) and client firms’ earnings comparability. If LLP auditors, who have a higher liability exposure than LLC auditors, are more consistent in implementing generally accepted accounting principles and executing firm-wide audit methodologies, client firms’ earnings comparability will increase.
Design/methodology/approach
Using data from China, the authors examine whether client firm-pairs of LLP auditors have higher earnings comparability than client firm-pairs of LLC auditors. The authors also perform cross-sectional tests to shed light on the mechanisms through which auditors’ litigation exposure affects client firms’ comparability.
Findings
The authors find that firm-pairs in which both firms are audited by LLP auditors exhibit higher earnings comparability than other firm-pairs. This result is stronger when client firms are audited by the same auditor, when client firms are audited by the top 10 auditors and when the auditors are less dependent on the client firms. The authors also document that firm-pairs in which both firms are audited by LLP auditors have lower average analyst earnings forecast error and forecast dispersion.
Originality/value
To the best of the author’s knowledge, this study is the first to examine the relation between auditor’s litigation exposure and client firms’ earnings comparability. It also extends the literature on audit firm organizational form and audit quality.

Abstract
Purpose
This paper aims to propose a new strategy to functionalize zeolitic imidazolate frameworks (ZIF-8) to improve its dispersion stability and tribological properties in lubricating oil.
Design/methodology/approach
Dialkyl dithiophosphate polydopamine ZIF-8 (DDP@PDA@ZIF-8) was prepared via mussel-inspired chemistry and the Michael addition reaction. The tribological properties of DDP@PDA@ZIF-8 as an additive in the white oil were evaluated with four-ball friction and wear tester at different temperatures. The worn surface was analyzed using X-ray photoelectron spectrum (XPS).
Findings
The as-prepared DDP@PDA@ZIF-8 shows high dispersion stability in the white oil. Tribological results confirmed that the DDP@PDA@ZIF-8 exhibited a small wear scar diameter at 25°C. However, excellent friction reduction and anti-wear properties were observed at 75°C. The XPS result indicates that a series of tribochemical reactions occurred on the worn surface, forming the complex protective film.
Originality/value
This paper provides a study of highly dispersed ZIF-8 as lubrication additives.

Abstract
Purpose
This paper aims to investigate the tribological properties of 1,4-bis(2-ethylhexyl) sulfosuccinate anion-based ionic liquids (ILs) when used as lubricant additives in synthetic ester oil.
Design/methodology/approach
The 1,4-bis(2-ethylhexyl) sulfosuccinate anion-based ILs containing different cation-imidazolium and organo-ammonium were synthesized and characterized. Their tribological performances as lubricant additives were assessed on ball-on-flat tribological tester. Their compatibility with typical additives (such as viscosity improver, antioxidant, pour point depressant and anti-rusting agent) were evaluated on a four-ball friction and wear tester.
Findings
It was found that the synthesized ILs demonstrated more effective friction reduction and antiwear properties than the base synthetic ester oil. The ILs worked well with the other typical additives, such as viscosity improver, antioxidant, pour point depressant and anti-rusting agent.
Originality/value
The results of the experimental studies demonstrated the potential of 1,4-bis(2-ethylhexyl) sulfosuccinate anion-based ILs as additives for improving friction reduction and antiwear abilities of synthetic ester oil.

Abstract
Purpose
The mixture of attapulgite and bentonite was used as a thickener, and polyalphaolefin was used as the base oil to prepare the new lubricating grease. Some solid particles such as Polytetrafluoroethene (PTFE), MoS2, nano-calcium carbonate and graphite were added in the new lubricating grease as anti-wear additives to investigate the tribological sensitivity.
Design/methodology/approach
The new lubricating grease was evaluated by optimol-SRV reciprocating friction and wear tester, and the wear volumes were determined using a MicroXAM-3D. At the same time, the dropping point and the cone penetration were investigated and analyzed. The tribological properties of the new lubricating grease and the sensitivity of some solid lubricating additives to the new lubricating base grease were investigated; pure organic-bentonite and pure organic-attapulgite base grease were used as contrast.
Findings
The new lubricating grease based on the surface-modified bentonite/attapulgite clay base grease was synthesized with a relatively high dropping point, and the mass ratio is 25/75 bentonite/attapulgite clay base grease, having a better tribological performance. MoS2 was used as an anti-wear additive that has good tribological sensitivity to the new lubricating base grease.
Originality/value
The main innovative thought of this work lies in the mixture of attapulgite and bentonite used as thickener. A relevant report is not available at present.

Abstract
Purpose
The Denial of Service (DoS) attack is a category of intrusion that devours various services and resources of the organization by the dispersal of unusable traffic, so that reliable users are not capable of getting benefit from the services. In general, the DoS attackers preserve their independence by collaborating several victim machines and following authentic network traffic, which makes it more complex to detect the attack. Thus, these issues and demerits faced by existing DoS attack recognition schemes in cloud are specified as a major challenge to inventing a new attack recognition method.
Design/methodology/approach
This paper aims to detect DoS attack detection scheme, termed as sine cosine anti coronavirus optimization (SCACVO)-driven deep maxout network (DMN). The recorded log file is considered in this method for the attack detection process. Significant features are chosen based on Pearson correlation in the feature selection phase. The over sampling scheme is applied in the data augmentation phase, and then the attack detection is done using DMN. The DMN is trained by the SCACVO algorithm, which is formed by combining sine cosine optimization and anti-corona virus optimization techniques.
Findings
The SCACVO-based DMN offers maximum testing accuracy, true positive rate and true negative rate of 0.9412, 0.9541 and 0.9178, respectively.
Originality/value
The DoS attack detection using the proposed model is accurate and improves the effectiveness of the detection.

Abstract
Purpose
The purpose of this study is to investigate the impact of internal control weaknesses on accounting conservatism in Chinese listed firms. It also investigates the relationship between the demand for external audit and accounting conservatism, and whether additional assurance of internal control reports (ICRs) can mitigate the negative impact of ICWs on accounting conservatism.
Design/methodology/approach
An empirical research approach is taken through the use of ordinary least squares (OLS) models and hand-collected internal control weakness data from ICRs released by Chinese listed firms.
Findings
The results of this paper show that the existence of ICWs has a negative effect on accounting conservatism in China. Further, the results demonstrate that both accounting-related and non-accounting-related ICWs affect accounting conservatism. The authors also find that there is a complementary relationship between accounting conservatism and the demand for additional assurance of ICRs, and additional assurance of ICRs can mitigate the negative impact of ICWs on accounting conservatism.
Practical Implications
This study provides timely evidence to Chinese regulators of the possible economic consequences of the official implementation of internal control standard in China from 2012. The findings of this paper can also benefit regulators around the world and, in particular, the regulators in emerging markets that are considering implement regulations similar to the US SOX.
Originality/value
The paper demonstrates that a wider scope of ICWs, including non-accounting-related ICWs, also has a significant impact on accounting conservatism. Therefore, this research provides a more general evidence on the relationship between internal control quality and accounting conservatism.

Abstract
Purpose
This paper analyses the role of accounting information quality on leverage adjustments. More specifically, the authors investigate whether a better accounting information leads to a higher speed of adjustment to the target financial leverage.
Design/methodology/approach
The authors use a two-step method. They first estimate the target financial structure and then the influence of accruals quality on the speed of adjustment to this target. The study sample consists of French listed companies in the CAC All-Tradable index. The sample contains 210 companies and 1,713 observations.
Findings
Accounting literature showed the positive influence of accounting quality on financial management. The study findings are in line with these results. The authors give evidence of that a better quality of accruals is associated with a greater speed of adjustment.
Research limitations/implications
A common limitation in this field is the use of proxies. This makes results harder to generalize. For this reason, the authors implemented several models to improve the robustness of their results.
Practical implications
The authors give evidence that firms have an incentive to disclose a good-quality accounting information. A weak accounting quality prevents firms from adjusting their leverage to their financial target and therefore reduce their value.
Social implications
This work shows the need for accounting standardization bodies to strive to produce accounting standards allowing the production of high-quality accounting information. In a teaching dimension, these results highlight the importance in corporate finance of acquiring expertise in quality accounting information analysis.
Originality/value
This work is original because the authors study the influence of accounting quality on speed of adjustments of firms operating in the same legal environment and using the same accounting standards, when previous work compared different accounting frameworks. The French context is characterized by the weakness of market mechanisms and the important role of banks. These characteristics are known to reduce the role of accounting information in financing process. This result is interesting because the authors demonstrate that firms operating in this context still have an incentive in producing high accounting quality information.

Abstract
Purpose
The purpose of this paper is to examine the effect of the financial structure on innovation.
Design/methodology/approach
We utilize the matched firm-level data from two sources: the World Bank Enterprise Survey and the Innovation Follow-Up Survey. A total of 3,664 firms from 11 African countries are included.
Findings
The authors find a financially constrained and low technology-intensive firm that uses internal finance more than its peers is less likely to innovate. Our results also show that a firm that uses new equity and debt finance more than its peers is more likely to innovate. The results particularly suggest the significant effect of bank and trade credit finance on firms’ innovation. The extent and, in some cases, the direction of the effect of dependence on internal finance, new equity finance and debt finance on innovation vary due to the heterogeneity in firm size, age and ownership status. Corporate innovation is also associated with firm size, R&D, cooperation, staff training, public support, exportation and group membership.
Practical implications
The management of companies, particularly financially constrained firms, should reduce their dependence on internal finance, which negatively affects their innovation. As a remedy, they could improve their reliance on new equity finance and debt finance, especially bank finance and trade credit finance, which positively affect their innovativeness.
Social implications
A pending policy task for African business leaders is to design and evaluate reforms that help create strong financial sectors willing to provide capital to a broad range of firms, particularly small and young firms.
Originality/value
This study adds new evidence to the recent surge of debate on the trade-off between going public, using debt or heavily using internal sources to finance innovative projects, and which of these is more important in promoting firm-level innovation.
