This paper aims to straighten out the research progress in the field of maker education, summarize the research hotspots and frontiers of maker education at home and abroad and provide path optimization suggestions for the research and development of this field.

In total, 751 pieces of domestic and the foreign maker education research literature from 2014 to 2021 are retrieved and screened, and literature analysis methods such as keyword analysis and clustering map analysis are used to quantitatively analyze the quantity distribution, published journals, core authors, research institutions and subject keywords of the maker education literature.

It is found that research in this field is still in the development stage, but the pandemic has severely inhibited maker education and related research. Frontiers at home and abroad have begun to pay attention to the impact of humanistic care on maker education. Strengthening the dialog between multidisciplinary theories requires cross-disciplinary research. Regional and cross-field cooperation and fully grasping the actual situation and constraints of the development of maker education are the cornerstones of bold innovation in maker education research.

This paper uses bibliometric analysis to reveal the severe challenges to the development of maker education due to the normalization of the epidemic. By excavating the research hotspots and research frontiers in this field, it fills the gap that the current research in the field of maker education has not yet formed a complete theoretical framework and evaluation system.

This study aims to understand how abusive supervision influences employees’ unethical pro-organizational behavior (UPB). In particular, the mediating effect of moral disengagement and moderating role of traditionality on this relationship were examined.

This study conducted a two-wave questionnaire survey using data collected from 629 employees from different companies in China. Moderated mediation analysis was conducted to test the hypotheses.

The results show that moral disengagement mediates the relationship between abusive supervision and employees’ UPB. Employee traditionality enhances the relationship between abusive supervision and moral disengagement as well as the indirect effect of abusive supervision on employees’ UPB via moral disengagement.

First, by exploring the positive impact of abusive supervision on UPB, the authors enhance the current understanding of the role of negative leadership in the development of UPB and enrich the research on the antecedents of UPB and outcomes of abusive supervision. Second, based on social cognitive theory, this study enriches the literature on abusive supervision and employee UPB by identifying moral disengagement as a mediator. Third, to the best of the authors’ knowledge, the authors are among the first to incorporate traditionality to tell a Chinese story about how traditional employees respond to the effects of abusive supervision on UPB, providing a new lens for the cultural boundary condition in the occurrence mechanism of UPB.

This paper aims to investigate the influence of over-allocation and under-allocation of family board seats on the corporate investment efficiency.

Based on the perspective of altruistic behavior, this paper theoretically analyzes the relationship between the preference of family board seats allocation and corporate investment efficiency, and designs the research. On this basis, we use STATA14.0 as an analysis tool to empirically test the relationship between the preference of family family board seats allocation and corporate investment efficiency, and consider the impact of different governance scenarios.

This study finds that firms with a higher over-allocation degree of family board seats invest more efficiently, evidenced by significantly suppressed over-investment rather than mitigated under-investment. However, we do not find evidence that the higher degree of under-allocation of family board seats contribute to lower corporate investment efficiency. Additionally, this study finds that the positive relationship between the over-allocation degree of family board seats and corporate investment efficiency is more pronounced for firms with higher separation of cash flow rights and control rights, and weaker regional law system environment. Our mechanism discussion shows that the higher over-allocation level of family board seats contributes to the mitigation of agency costs for family firms by reducing the tendency for non-family boards to vote “against board proposals” and the appropriation behavior of the controlling family, and eventually improving corporate investment efficiency.

This paper examines the relationship between the preference of family board seats allocation and corporate investment efficiency from the perspective of altruistic behavior. Unlike previous studies, this paper distinguishes the governance effects arising from over-allocation and under-allocation of family board seats. Additionally, different governance scenarios are incorporated into the decision-making mechanism of the board of family firms, and the influences of the divergence of cash-flow and control rights and a weaker regional law system on the governance effect of the preference of family board seat allocation are analyzed.

This paper aims to present an adaptive sliding mode control (ASMC) for tunnel boring machine cutterhead telescopic system with uncertainties to achieve a high-precision trajectory in complex strata. This method could be applied to solve the problems caused by linear and nonlinear model uncertainties.

First, an integral-type sliding surface is defined to reduce the static tracking error. Second, a projection type adaptation law is designed to approximate the linear and nonlinear redefined parameters of the electrohydraulic system. Third, a nonlinear robust term with a continuous approximation function is presented for handling load force uncertainty and reducing sliding mode chattering. Moreover, Lyapunov theory is applied to guarantee the stability of the closed-loop system. Finally, the effectiveness of the proposed controller is proved by comparative experiments on a scaled test rig.

The linear and nonlinear model uncertainties lead to large variations in the dynamics of the mechanism and the tracking error. To achieve precise position tracking, an adaptation law was integrated into the sliding mode control which compensated for model uncertainties. Besides, the inherent sliding mode chattering was reduced by a continuous approximation function, while load force uncertainty was solved by a nonlinear robust feedback. Therefore, a novel ASMC for tunnel boring machine cutterhead telescopic system with uncertainties can improve its tracking precision and reduce the sliding mode chattering.

To the best of the authors’ knowledge, the ASMC is proposed for the first time to control the tunnel boring machine cutterhead telescopic system with uncertainties. The presented control is effective not only in control accuracy but also in parameter uncertainty.

This paper aims to explore Chinese entrepreneurs’ perceptions and interpretations of social media marketing (SMM) in their daily business practices.

A qualitative approach was adopted to explore the phenomenon. Specifically, 18 in-depth interviews were conducted among Chinese entrepreneurs to obtain their experiences of and perceptions on SMM.

Findings revealed that Chinese entrepreneurs have good understandings of SMM. They believe SMM is a necessary way to interact with customers and SMM can provide flexibility and sensitivity which are important for entrepreneurial marketing and are not easy to achieve through traditional marketing activities. When they choose social media applications, they will match the purpose of marketing activity with the characteristics of the social media. They have developed the specific strategies for different social media applications. In the meantime, they are facing some challenges, such as breaking the communication clutter, measuring the results and over depending on social media.

Findings of the current study extend the uses and gratifications theory to the context of business-oriented media usage. In addition, findings of the study expand previous literature by enriching the theoretical understanding of the concept of entrepreneur and entrepreneurial marketing in new social and cultural contexts. Finally, findings of the current study also supplement previous research on social media advertising by uncovering rich meanings of SMM from business owners’ emic perspective.

This study aims to explore the concept of frontline employee’s brand sabotage behaviour (BSB) and the influencing factors of BSB in the hotels and their partner travel agencies from the perspective of perceived justice and establishes a moderating mechanism based on emotional resource supplementation.

This paper developed a measurement scale of BSB through interviews with hotel employees and multiple rounds of questionnaire surveys in Study 1 and tested the research model and hypotheses using a structural equation model analysis in Study 2.

The results of multiple rounds of surveys indicate that a positive perception of procedural justice helps to restrain employees from implementing BSB but the employee’s perceived customer injustice can directly stimulate not only the BSB but also reduce employees’ perception of the level of procedural justice. However, when employees’ self-efficacy for emotional regulation is higher, the positive relationship between customer injustice and BSB and the negative impact on procedural justice is weakened.

The findings suggest that managers should implement practices to suppress BSB by actively managing the service interaction process and reduce the instances of unjust customer behaviours, while preventing employees from sabotaging brands at both organizational and employee levels by promoting organizational procedural justice and employees’ self-efficacy for emotional regulation.

The research results enrich the discussion on the integration of resources in the process of value co-creation and the common sabotage of brand value caused by resource abuse. Further, this study also supplements and perfects the theory of service brand management.

This paper explores the role of traditional Chinese medicine (TCM) as a tourism recovery drawcard to boost China's inbound tourism after COVID-19.

This paper employed a mixed method involving a cross-disciplinary literature review along with reflections from experts in TCM and health communication to inform tourism management. Specifically, this paper examines TCM and its potential benefits as a medical tourism drawcard to combat COVID-19. The selected literature focusses on the image and merits of TCM to frame how this medical philosophy can be used to position China as a tourist destination. Reflections on the use of TCM as a tourism marketing tool can guide promotional strategies from the Chinese government and destination managers during and after COVID-19.

The Chinese government, the tourism industry (e.g. destination managers), the media and tourists must focus on three aspects of the role of TCM: to provide medical benefits to travellers amid COVID-19 and beyond, elevate China as a destination for global medical tourists and be leveraged as a tool for economic recovery.

The paper builds a tourism recovery framework for stakeholders to adopt tailored TCM communication strategies to boost its inbound tourism programme.

This paper is the first academic paper to review TCM comprehensively and critically in relation to China tourism and post-COVID-19 recovery measures.

The mathematical model of a two-phase Lamé-Clapeyron-Stefan problem for a semi-infinite material with a density jump is considered. The purpose of this paper is to study the analytical solutions of the models and show the performance of several parameters.

To describe the heat conduction, the Caputo type time fractional heat conduction equation is used and a convective term is included since the changes in density give rise to motion of the liquid phase. The similarity variables are used to simplify the models.

The analytical solutions describing the changes of temperature in both liquid and solid phases are obtained. For the solid phase, the solution is given in the Wright function form. While for the liquid phase, since the appearance of the advection term, an approximate solution in series form is given. Based on the solutions, the performance of the parameters is discussed in detail.

From the point of view of mathematics, the moving boundary problems are nonlinear, so barely any analytical solutions for these problems can be obtained. Furthermore, there are many applications in which a material undergoes phase change, such as in melting, freezing, casting and cryosurgery.

Efforts to contribute to the Sustainable Development Goals are increasingly part of tourism business planning, forming part of their business policies, linking with society and generating a sustainable hotel offer. The great impact it causes and, which in the short term it will achieve, digital tools in hotel activities can be evidenced. It will also help to collect the information that serves for the certifications of hotel companies. In spite of all the efforts, there is still a great knowledge gap that needs to be filled to achieve the expected business results and that it can be evidenced that the hospitality industry is now more than ever focussed on the care of its workers and on contributing to the sustainability of the world.

This study aims to propose a series of numerical and surrogate models to investigate the aerodynamic pressure inside cracks in high-speed railway tunnel linings and to predict the stress intensity factors (SIFs) at the crack tip.

A computational fluid dynamics (CFD) model is used to calculate the aerodynamic pressure exerted on two cracked surfaces. The simulation uses the viscous unsteady κ-ε turbulence model. Using this CFD model, the spatial and temporal distribution of aerodynamic pressure inside longitudinal, oblique and circumferential cracks are analyzed. The mechanism behind the pressure variation in tunnel lining cracks is revealed by the air density field. Furthermore, a response surface model (RSM) is proposed to predict the maximum SIF at the crack tip of circumferential cracks and analyze its influential parameters.

The initial compression wave amplifies and oscillates in cracks in tunnel linings, resulting from an increase in air density at the crack front. The maximum pressure in the circumferential crack is 2.27 and 1.76 times higher than that in the longitudinal and oblique cracks, respectively. The RSM accurately predicts the SIF at the crack tip of circumferential cracks. The SIF at the crack tip is most affected by variations in train velocities, followed by the depth and length of the cracks.

The mechanism behind the variation of aerodynamic pressure in tunnel lining cracks is revealed. In addition, a reliable surrogate model is proposed to predict the mechanical response of the crack tip under aerodynamic pressures.
