Abstract
Purpose
The phenomenon of defamilization of family firms is gradually increasing for the growth of family firms, that is, nonfamily executives are increasingly present in the executive teams of family firms. Although previous scholars have identified various determinants of family firms' defamilization, whether and when innovation underperformance affects the decision to defamilize family firms has not been explore. This study aims to fill the aforementioned research gaps.
Design/methodology/approach
This study empirically tests the theoretical view based on the data of Chinese A-share family listed companies from 2009 to 2017.
Findings
The authors found that innovation underperformance drives family companies to increase the percentage of nonfamily executives in their executive teams. Further, the authors found that family firms are less willing to hire nonfamily executives with an increase in socioemotional wealth, particularly when founders of such businesses serve as directors or are major shareholders, even when they are not directors.
Originality/value
This study shows that innovation underperformance and socioemotional wealth are important predictors of family firms’ defamilization decisions.

Abstract
Purpose
Based on the socioemotional wealth theory, this study aims to empirically investigate how founder reign, that is a founder serving as a cheif executive officer (CEO) or chairman, influences family firms' research and development (R&D) investment in emerging economies (e.g. China).
Design/methodology/approach
This study empirically tested the hypotheses based on a sample of listed Chinese family companies from 2008 to 2018.
Findings
Founder reign has a negative impact on family firms' R&D investment. Particularly, the negative impact of the founder serving as chairman on family firms' R&D investment is larger than the negative impact of the founder serving as CEO on family firms' R&D investment. Founder's military experience weakens the negative impact of founder reign on family firms' R&D investment, but founder's executive master of business administration (E)MBA experience has no moderating effect on this relationship.
Originality/value
First, the authors contribute to the family firm innovation literature by providing an alternative but complementary explanation of why family firms have relatively low R&D investment levels. This research shows that founder reign is a key reason for family firms in China eschewing R&D investment. Second, by incorporating the founder serving as CEO and the founder serving as chairman into the analytical framework, and then examining their impact on family firms' R&D investment, our research helps us to fully understand the impact of founder reign on firm strategic actions. Third, we contribute to the “founder reign-firm strategic actions” framework by revealing how founders' human capital profoundly affects the relationship between founder reign and family firms' R&D investment.

Abstract
Purpose
With the development of the economy, an increasing number of listed companies form subsidiaries in China. Though the increase in the number of subsidiaries affects the hierarchical structure and risk of conglomerates, few studies relate the hierarchical relationship between the parent company and its subsidiaries to its capital market performance at the conglomerate level. Therefore, this study aims to investigate the relationship between the number of subsidiaries and crash risk.
Design/methodology/approach
Using a sample of all the A-share companies in the Shanghai and Shenzhen stock markets from 2007 to 2015, this study conducts multivariate regression analyses between the number of subsidiaries and the stock price crash risk.
Findings
This study finds an inversed U relationship between the number of subsidiaries and the stock price crash risk, and the above inversed U relationship is steeper in conglomerates with stronger managerial power and less finance distress.
Originality/value
This research has an incremental contribution to the agency problem and governance effect of the parent–subsidiary system in conglomerates. To the best of the authors’ knowledge, this is the first study to show a significant quadratic relationship between the future crash risk and the number of subsidiaries. This paper provides new evidence that the number of subsidiaries has an incremental ability to predict future firm-specific crash risk above other predictors identified by previous research.

Abstract
Purpose
Based on socioemotional wealth theory, the authors explore the impact of founder domination (with the founder as the chairman or CEO) on the earnings management activities of family firms and examine the moderating effect of the industry environment on the above relationship.
Design/methodology/approach
Based on the multivariate regression model, the authors test the theoretical view on the empirical data of Chinese family-owned listed companies.
Findings
The authors propose and find that under founder domination, family firms are unlikely to engage in earnings management activities. Furthermore, the authors find that industry growth enhances the above relationship, while industry competition weakens it.
Originality/value
First, by clarifying the importance and heterogeneous impacts of the founder serving as chairman or CEO on China's family firms' earnings management, this research contributes to a fuller understanding of the impact of founder domination on the business activities of firms, especially family firms. Second, the authors contribute to the literature that examines the antecedents of earnings management, particularly in family firms. Third, the authors contribute to the study of the boundary conditions of the “founder domination-firms’ business activities” framework.

This paper aims to carry out the research on the influence of ground effect on the performance of robotic fish propelled by oscillating paired pectoral fins.
Abstract
Purpose
This paper aims to carry out the research on the influence of ground effect on the performance of robotic fish propelled by oscillating paired pectoral fins.
Design/methodology/approach
The two-dimensional ground effect model of the oscillating pectoral fin without considering flexible deformation is established by introducing a two-dimensional fluid ground effect model. The parameters of the influence of ground effect on the oscillating pectoral fin are analyzed. Finally, the ground effect test platform is built, and a series of hydrodynamic experiments are carried out to study the influence of ground effect on the propulsion performance of the robotic fish propelled by oscillating paired pectoral fins under different motion parameters.
Findings
The thickness of the trailing edge and effective clearance are two important parameters that can change the influence of ground effect on the rigid pectoral fin. The experimental results are consistent with that obtained through theoretical analysis within a certain extent, which indicates that the developed two-dimensional ground effect model in this paper can be used to analyze the influence of ground effect on the propulsion performance of the oscillating pectoral fin. The experiment results show that the average thrust increases with the decreasing distance between the robot fish and the bottom. Meanwhile, with the increase of oscillation frequency and amplitude, the average thrust increases gradually.
Originality/value
The developed two-dimensional ground effect model provides the theoretical basis for the further research on the influence of ground effect on the propulsion performance of the oscillating pectoral fin. It can also be used in the design of the bionic pectoral fins.

Abstract
Purpose
The purpose of this study is to explore the association between eating patterns, social identity and the well-being of adolescents via a mixed methods study of Chinese teenagers. The specific research questions presented in this study are as follows: What is the relationship between social eating and well-being? How is the relationship between social eating and well-being mediated by social identity?
Design/methodology/approach
This study is based on a sequential mixed methods study, including interviews with 16 teenage–parent dyads, and a large-scale survey of over 1,000 teenagers on their eating patterns, conducted with the support of public schools. A model that tests relationships among social eating, social identity and subjective well-being is developed and tested.
Findings
The results show that dining with family members leads to improved subjective well-being for teenagers, through a partial mediator of stronger family identity. However, dining with peers is not found to influence subjective well-being.
Research limitations/implications
The privileged position of family meals demonstrated through this study may be an artifact of the location of this study in one Chinese city. Further research is needed related to the connections among social identity, objective well-being and the social patterns of teenagers’ food consumption behavior.
Practical implications
To improve the subjective well-being of teenagers, families, public policy-makers and food marketers should support food consumption patterns that promote family meals.
Originality/value
While many food-related consumer studies focus on the individual, social and environmental influences of food choices of adolescents, few studies address how eating patterns affect overall well-being. These results reinforce the importance of understanding the effect of the social context of teenagers’ eating patterns on health and well-being.

Abstract
Purpose
The purpose of this paper is to promote the efficiency of RGB-depth (RGB-D)-based object recognition in robot vision and find discriminative binary representations for RGB-D based objects.
Design/methodology/approach
To promote the efficiency of RGB-D-based object recognition in robot vision, this paper applies hashing methods to RGB-D-based object recognition by utilizing the approximate nearest neighbors (ANN) to vote for the final result. To improve the object recognition accuracy in robot vision, an “Encoding+Selection” binary representation generation pattern is proposed. “Encoding+Selection” pattern can generate more discriminative binary representations for RGB-D-based objects. Moreover, label information is utilized to enhance the discrimination of each bit, which guarantees that the most discriminative bits can be selected.
Findings
The experiment results validate that the ANN-based voting recognition method is more efficient and effective compared to traditional recognition method in RGB-D-based object recognition for robot vision. Moreover, the effectiveness of the proposed bit selection method is also validated to be effective.
Originality/value
Hashing learning is applied to RGB-D-based object recognition, which significantly promotes the recognition efficiency for robot vision while maintaining high recognition accuracy. Besides, the “Encoding+Selection” pattern is utilized in the process of binary encoding, which effectively enhances the discrimination of binary representations for objects.

Abstract
Purpose
In this paper, the authors study the production and pricing decisions of a remanufacturing supply chain composed of a supplier, an assembler and a remanufacturer, in which the remanufacturing of components requires patent licensing from the supplier.
Design/methodology/approach
The authors consider three different models with government subsidy for remanufacturing: (1) no government subsidies; (2) the government subsidizes the remanufacturing behavior of the supplier and (3) the government subsidizes the remanufacturing behavior of the remanufacturer and use the Stackelberg game model to solve and analyze the equilibrium wholesale prices of components and the equilibrium outputs of new and remanufactured products under three subsidy modes.
Findings
The results show that the equilibrium wholesale prices of two kinds of components decrease with the unit patent licensing fee and the unit government subsidy, and the equilibrium quantity of the remanufactured products under the three modes is obviously higher than that of the new products.
Originality/value
Finally through numerical simulation, it is found that the equilibrium profits of the supplier, the manufacturer and the supply chain increase monotonously in relation to the unit government subsidy, while the optimal profit of the assembler in relation to the unit government subsidy tends to decrease first and then increase.

Abstract
Purpose
Drawing upon the conservation of resources (COR) theory, this study aims to examine whether ego depletion mediates the relationship between negative workplace gossip and employees’ service sabotage behavior and whether psychological resilience moderates the relationship between negative workplace gossip and service sabotage behavior through the mediator of ego depletion among hotel frontline employees and their colleagues.
Design/methodology/approach
A paired sample was collected at three-time points from employees and their colleagues working in hotels in Guizhou province, China. The PROCESS macro for SPSS was applied to examine the moderated mediation model.
Findings
The results showed that negative workplace gossip has a positive effect on employee service sabotage behavior, and that ego depletion mediates the relationship between negative workplace gossip and employee service sabotage behavior. Psychological resilience weakens the relationship between negative workplace gossip and ego depletion, as well as the indirect effect of negative workplace gossip on employee service sabotage behavior through ego depletion.
Originality/value
The present research provides a thorough understanding of when and how negative workplace gossip influences employee service sabotage behavior in the hospitality industry. The findings of this moderated mediation relationship expanded the boundary conditions of negative workplace gossip and employee service sabotage behavior.

Abstract
Purpose
This study aims to review the recent advancements in high entropy alloys (HEAs) called high entropy materials, including high entropy superalloys which are current potential alternatives to nickel superalloys for gas turbine applications. Understandings of the laser surface modification techniques of the HEA are discussed whilst future recommendations and remedies to manufacturing challenges via laser are outlined.
Design/methodology/approach
Materials used for high-pressure gas turbine engine applications must be able to withstand severe environmentally induced degradation, mechanical, thermal loads and general extreme conditions caused by hot corrosive gases, high-temperature oxidation and stress. Over the years, Nickel-based superalloys with elevated temperature rupture and creep resistance, excellent lifetime expectancy and solution strengthening L12 and γ´ precipitate used for turbine engine applications. However, the superalloy’s density, low creep strength, poor thermal conductivity, difficulty in machining and low fatigue resistance demands the innovation of new advanced materials.
Findings
HEAs is one of the most frequently investigated advanced materials, attributed to their configurational complexity and properties reported to exceed conventional materials. Thus, owing to their characteristic feature of the high entropy effect, several other materials have emerged to become potential solutions for several functional and structural applications in the aerospace industry. In a previous study, research contributions show that defects are associated with conventional manufacturing processes of HEAs; therefore, this study investigates new advances in the laser-based manufacturing and surface modification techniques of HEA.
Research limitations/implications
The AlxCoCrCuFeNi HEA system, particularly the Al0.5CoCrCuFeNi HEA has been extensively studied, attributed to its mechanical and physical properties exceeding that of pure metals for aerospace turbine engine applications and the advances in the fabrication and surface modification processes of the alloy was outlined to show the latest developments focusing only on laser-based manufacturing processing due to its many advantages.
Originality/value
It is evident that high entropy materials are a potential innovative alternative to conventional superalloys for turbine engine applications via laser additive manufacturing.
