Abstract
Purpose
As an ancient art form, embroidery has strong practicality and artistic value. However, current embroidery style migration models produce images with unclear textures and a lack of stitch detail. So, in this paper, we propose a cyclic consistent embroidery style migration network with texture constraints, which is called Texture Cycle GAN (TCGAN).
Design/methodology/approach
The model is based on the existing Cycle GAN network with an additional texture module. This texture module is implemented using a pre-trained Markovian adversarial network to synthesize embroidery texture features. The overall algorithm consists of two generative adversarial networks (for style migration) and the Markovian adversarial network (for texture synthesis).
Findings
Qualitative and quantitative experiments show that, compared with the existing convolutional neural network style transfer algorithm, the introduction of the texture-constrained embroidery style transfer model TCGAN can effectively learn the characteristics of style images, generate digital embroidery works with clear texture and natural stitches and achieve more realistic embroidery simulation effects.
Originality/value
By improving the algorithm for image style migration and designing a reasonable loss function, the generated embroidery patterns are made more detailed, which shows that the model can improve the realism of embroidery style simulation and help to improve the standard of embroidery craftsmanship, thus promoting the development of the embroidery industry.

Abstract
Purpose
Healthcare is a service industry where fulfilling the needs of patients (customers) is challenging. Various factors, including cost, system complexity, staffing behaviours and technological advances, play vital roles. Drawing upon social exchange theory, this study seeks to determine how paternalistic leadership (authoritarianism, benevolence and morality) influences employee service innovative behaviour and counterproductive work behaviour via perceived supervisor support in the healthcare sector. Additionally, the study investigates the role of the public service motivation of individuals as a moderating factor in this relationship.
Design/methodology/approach
A pilot study and a main study were conducted to test the hypotheses. We collected data from healthcare professionals in Pakistan’s large public, private and semi-government hospitals. We applied bootstrapping with 5,000 replications and structural equation modelling to analyse the data.
Findings
Results indicate that authoritarianism was negatively associated with service innovative behaviour, whereas benevolent and moral behaviours were positively associated with service innovative behaviour via perceived supervisor support (mediation). Our findings shed light on the moderating role of public service motivation.
Originality/value
This empirical quantitative study has several theoretical and practical implications. Findings of our study provide evidence that a paternalistic leadership style can influence both positive (service innovative behaviour) and negative (counterproductive working behaviour) working behaviours simultaneously via perceived supervisor support at an individual level in the service (healthcare) industry. This study also highlights the moderating role of public service motivation as an individual motivation factor.

Abstract
Purpose
The main purpose of this study is to investigate the impact of state capital participation (SCP) on the corporate environmental engagement (CEE) of privately controlled listed firms in China.
Design/methodology/approach
We use a sample of 20,133 firm-year observations from 2009 to 2021. We use three different measures to proxy corporate environmental engagement and two different measures to proxy for state capital participation. We employ a difference-in-difference regression model to estimate the effect of state capital participation on corporate environmental engagement.
Findings
Using a sample of 20,133 firm-year observations from 2009 to 2021, we find that SCP significantly increases corporate expenditure on environmental protection, corporate environmental performance and ESG ratings. Specifically, SCP increases environmental investment capacity and attracts more media coverage, online attention and analysts’ following, which leads to better environmental engagement. Further analyses show that after state shareholders exit privately controlled firms, CEE deteriorates, while private capital injection in state-owned firms has no significant impact on CEE. The positive effect of SCP is stronger in privately controlled firms with local government ownership, a larger number of state shareholders, longer state shareholder holding periods, those without politically connected managers and firms operating in heavy pollution industries. Lastly, we show that minority government ownership reduces firm-level toxic emissions and enhances financial performance.
Research limitations/implications
We enrich the literature on the role of minority state ownership in corporate financial and environmental performance.
Originality/value
We enrich the literature on the role of minority state ownership in corporate financial and environmental performance. In light of the escalating environmental concerns and the growing emphasis on corporate environmental responsibility, this study highlights the beneficial role of minority government ownership in driving environmental performance. By providing resources and attracting external scrutiny, the government, as a minority shareholder, can significantly enhance the environmental engagement of privately controlled firms.

Abstract
Purpose
The purpose of this paper is to empirically analyze the impact of directors’ and officers’ (D&O) liability insurance on enterprise strategic change. It also explores the mediating role of litigation risk, the moderating roles of enterprise science and technology level and precipitation organizational slack between them. In addition, it examines the joint moderating roles of the top management team (TMT) external social network and enterprise science and technology level, and enterprise scale and precipitation organizational slack.
Design/methodology/approach
Using the unbalanced panel data of A-share listed companies in the Shanghai and Shenzhen stock exchanges of China from 2002 to 2020 as the research sample, this paper uses the ordinary least square method and fixed-effect model to study the relationship between D&O liability insurance and enterprise strategic change. The study also focuses on the mediating mechanism and moderating mechanisms between them.
Findings
The authors find that D&O liability insurance has an “incentive effect,” which can significantly promote enterprise strategic change. Litigation risk plays a partial mediating role between D&O liability insurance and enterprise strategic change. Enterprise science and technology level and precipitation organizational slack negatively moderate the relationship between D&O liability insurance and enterprise strategic change. TMT external social network and enterprise science and technology level, and enterprise-scale and precipitation organizational slack have joint moderating effects on the relationship between D&O liability insurance and enterprise strategic change.
Originality/value
This paper confirms the “incentive effect hypothesis” of the impact of D&O liability insurance on enterprise strategic change, which not only broadens the research perspective of enterprise strategic management but also further expands the research scope of D&O liability insurance. Besides, this paper thoroughly explores the influencing mechanisms between D&O liability insurance and enterprise strategic change, providing incremental contributions to the research literature in the field of enterprise risk management and corporate governance. The findings have practical guiding significance for expanding the coverage of D&O liability insurance, promoting the implementation of strategic changes and improving the level of corporate governance of Chinese enterprises.

Abstract
Purpose
In the contemporary globalized era, where conscientious and inclusive leadership (IL) are increasingly valued, cultivating altruistic prosocial tendencies (APT) among future leaders becomes critical. However, a significant gap persists in understanding the optimal approach for assisting young leaders with commendable social sensitivity. This study aims to examine the connection between IL and a leader’s APT and focuses on the moderating role of internalized values (IV) among young leaders in Indonesia.
Design/methodology/approach
The research adopted a quantitative methodology, using an online survey to gather data from 12.584 participants in the “Kampus Mengajar” program. The data analysis is conducted using structural equation modeling.
Findings
The study highlights the significant association between IL and APT among leaders, emphasizing the importance of inclusive approaches in fostering prosocial behavior. Additionally, it reveals the moderating impact of IVs, indicating that leaders who embrace values promoting societal belongingness are more inclined toward altruistic actions. This nuanced insight contributes to theoretical discourse and offers practical implications for organizations and educational institutions aiming to cultivate socially conscious leadership among young leaders.
Originality/value
This study advances scholarly understanding by exploring how IL shapes APT among young leaders, integrating insights from Role Identity and Role Identity Salience theory. By examining the moderating role of IVs, the study offers nuanced insights into the conditions that enhance this relationship.

This study aims to improve the positioning accuracy of a large-scale parallel pose alignment mechanism by calibration and error compensation.
Abstract
Purpose
This study aims to improve the positioning accuracy of a large-scale parallel pose alignment mechanism by calibration and error compensation.
Design/methodology/approach
The dynamic modelling of the parallel pose alignment mechanism is achieved using the Newton Euler method. Combined with a deformation compatibility analysis, the support force at the spherical hinge and the friction of the follow-up prismatic pair are calculated. The deformation of the moving platform in multi-pose space is analysed by the integral method, and a corresponding deformation model is established. Based on the calculated support force, friction and deformation, the deformation error is analysed. Combined with the calculated deformation error, kinematics calibration and positioning error compensation are carried out.
Findings
The simulation results show that the deviation of structural error identification is decreased from 3.03 × 10–1 mm to 6.8 × 10–2 mm. The experimental results show that the maximum pose errors after compensation are reduced from 2.77 mm to 6.5 × 10–1° to 3.9 × 10–1 mm and 3.7 × 10–1°, which verifies the effectiveness of the proposed method.
Originality/value
This method can be used in the field of aircraft assembly for the calibration and error compensation of a large-scale parallel pose alignment mechanism based on positioners.

Abstract
Purpose
The present article aims at systematizing the literature on EM that spans over three decades (1987–2023) to analyze the growth and development in the EM research following changes in reporting standards, economic conditions and legislations over the period.
Design/methodology/approach
The study covers 3,742 articles on earnings management (EM) indexed in SCOPUS and the Web of Science databases from 1987 to 2023. The study aims at the systematization of bibliometric data using R Studio, Biblioshiny and VOS Viewer software.
Findings
The study reveals that the research in the pre-SOX era gave more thrust to the development of cross-sectional models for the detection of accrual EM proxies, whereas research on EM had shifted to managerial discretions based on real transactions in the post-SOX era. Later, in the post-GFC era, the focus of EM research was redefined towards investor protection due to the collapse of the global economy that led to the erosion of investors’ wealth. In the modern era, research on EM focuses on ethical aspects such as CSR compliance, ESG framework and so on.
Practical implications
The findings of the study will aid the policymakers in addressing the EM based on real transactions and also incorporate the variations and changes in multiple green reporting standards to ensure fairness and transparency in reported figures.
Originality/value
The study contributes to the existing literature by quadrisecting the entire research on earnings management to analyze the growth and development in EM research and makes novel suggestions that future research on earnings management can be expanded towards the role of non-financial disclosure in managerial discretions and also the insider biases in green reporting.

Abstract
Purpose
This paper aims to compare the differences between single- and multi-person interactions in virtual tourism, underpinned by the stimulus-organism-response (S-O-R) framework and media richness theory (MRT).
Design/methodology/approach
In this study, quantitative data gathered from questionnaires applied to 558 individuals was analyzed by using partial least squares structural equation modeling. The moderating role of interaction type was tested through multigroup analysis (MGA).
Findings
The results showed that vividness positively influenced telepresence, perceived attractiveness and authentic experiences; telepresence positively affected authentic experiences and perceived attractiveness; and authentic experiences and perceived attractiveness positively impacted willingness to visit in both interaction groups. A difference was detected between the two groups in that perceptions of media vividness were more easily transformed into a willingness to visit through telepresence in the multi-person interaction group. Interaction type moderated the effect of vividness on telepresence. The vividness of the media had a more significant effect on telepresence among those who participated in virtual tourism together.
Originality/value
In this study, a model was developed to explain how media vividness affected willingness to visit by considering the relationships between telepresence, authentic experiences and perceived attractiveness in virtual reality, as well as the social interaction aspect.

Abstract
Purpose
With respect to severe working conditions such as heavy load and impact, this paper aims to investigate the friction reduction and anti-wear performance of kaolin and molybdenum dialkyl dithiophosphate (MoDDP) composite lubricant additives to improve the lubrication effect of a single additive.
Design/methodology/approach
A four-ball friction test was carried out to determine the optimal concentration of kaolin and organic molybdenum additives and the tribological properties of the kaolin/MoDDP composite lubricant additives. A ring block test of composite lubricant additives was designed to investigate its lubrication performance under the severe working conditions of low speed, heavy load and impact.
Findings
The results showed that the optimal addition mass fractions of kaolin and MoDDP were 4.0 and 1.5 Wt.%, respectively, when kaolin and MoDDP were used as single lubricant additives. Compared with the single additive, the 4.0 Wt.% kaolin/1.5 Wt.% MoDDP composite lubricant additive showed excellent friction reduction and anti-wear effects under heavy load and impact conditions. Physicochemical analysis of the wear surface revealed that the lamellar kaolin additive and MoDDP had excellent synergistic effects, and the friction process promoted the generation of lubricant films containing a chemically reactive layer of MoS2, MoO2, FeS2 and Fe2O3 and a physically adsorbent layer containing SiO2 and Al2O3, which play important roles in anti-wear and friction reduction.
Originality/value
The excellent friction reduction and anti-wear effects of lamellar silicate minerals and the excellent antioxidant properties and good synergistic effects of molybdenum were comprehensively used to develop the composite additives with great lubricating properties.
