Abstract
Self-cleaning surfaces have received a great deal of attention recently, both in theoretical studies and commercial applications. Lotus flowers are a symbol of purity in Asian cultures; even though they grow in muddy waters, they remain clean and uncontaminated. The “self-cleaning” surface of their leaves is hydrophobic and rough, showing a micro- and nano-scale morphology. The micro-reliefs of lotus leaves are mimicked by using polyvinylidene fluoride (PVDF) film and the nano-scale peaks on top of the micro-reliefs are implemented by a reaction between CH3SiCl3 and the reactive groups of the PVDF film treated by oxygen plasma. A lotus leaf-like surface of the PVDF film is clearly observed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Elemental composition analysis by x-ray photoelectron spectroscopy (XPS) reveals that the material of the nanostructure of the PVDF film is polymethylsiloxane. The superhydrophobic property of the mimicked self-cleaning surface is validated by the water contact and sliding angles on the lotus leaf-like PVDF film, which are 165°and 4°, respectively. In this case, water drops can easily move off the PVDF surface, carrying dust away and leaving a clean surface

Abstract
Purpose
Auxetics metamaterials show high performance in their specific characteristics, while the absolute stiffness and strength are much weaker due to substantial porosity. This paper aims to propose a novel auxetic honeycomb structure manufactured using selective laser melting and study the enhanced mechanical performance when subjected to in-plane compression loading.
Design/methodology/approach
A novel composite structure was designed and fabricated on the basis of an arrowhead auxetic honeycomb and filled with polyurethane foam. The deformation mechanism and mechanical responses of the structure with different structural parameters were investigated experimentally and numerically. With the verified simulation models, the effects of parameters on compression strength and energy absorption characteristics were further discussed through parametric analysis.
Findings
A good agreement was achieved between the experimental and simulation results, showing an evidently enhanced compression strength and energy absorption capacity. The interaction between the auxetic honeycomb and foam reveals to exploit a reinforcement effect on the compression performance. The parametric analysis indicates that the composite with smaller included angel and higher foam density exhibits higher plateau stress and better specific energy absorption, while increasing strut thickness is undesirable for high energy absorption efficiency.
Originality/value
The results of this study served to demonstrate an enhanced mechanical performance for the foam filled auxetic honeycomb, which is expected to be exploited with applications in aerospace, automobile, civil engineering and protective devices. The findings of this study can provide numerical and experimental references for the design of structural parameters.

Abstract
Purpose
The purpose of this paper is twofold: first, to examine a customer orientation mechanism through which abusive supervision influences retail salespeople’s job performance; and second, to investigate how abusive supervision’s effects may be moderated by the same leader’s use of contingent punishment and contingent reward.
Design/methodology/approach
Two studies provide consistent findings. Study 1 used the field survey data from 129 salespeople in 42 retail stores. The proposed moderated mediation model was estimated using the random coefficient modeling technique. Findings were replicated in Study 2, in which data were collected from a sample of 679 US retail salespeople recruited through M-Turk.
Findings
Results from both studies show that abusive supervision reduces salespeople’s job performance through lowering their customer orientation. Furthermore, the use of contingent punishment from the same supervisor buffers abusive supervision’s detrimental effect, whereas the use of contingent reward augments it.
Research limitations/implications
The issues the authors address in this research have significant implications for the literature of abusive supervision and retail selling. First, the authors contribute to the abusive supervision literature by pointing it out that the negative effect of abusive supervision can spill over to organizations’ external stakeholders, namely, customers. Previous research on abusive supervision has mainly focused on how abused subordinates exhibit hostile acts directed against the supervisor, coworkers and the organization (Tepper et al., 2017), with little attention paid to abusive supervision’s impact on organizations’ external stakeholders such as customers. This research fills the void by placing impaired customer-orientation as a critical consequence of abusive supervision. Second, this research tests a contingent self-regulation impairment model of abusive supervision and advances our understanding about how the same supervisor’s functional leadership behaviors (contingent reward/punishment) may set contingencies for the effect of abusive supervision on employee outcomes. This investigation clears the doubts about whether the use of functional leadership behaviors along with abusive supervision buffers or aggravates the detrimental effect of the latter. Finally, this study’s findings shed new insights to marketing practitioners, especially in understanding how salespeople may vent their stress on the customers when being abused by their supervisors. Without this in mind, supervisors may not be aware of the consequences of their abusive behavior and may even develop an illusion that such a practice worked. This research shows that abusive supervision can lower employees’ customer orientation, which will hurt the company in the long run.
Practical implications
The findings intend to provide important guidelines for companies to develop effective workshops and training programs to combat the detrimental effects of abusive supervision in the retailing industry. For example, the findings shed new insights in understanding how employees may vent their stress on the customers when being abused by their supervisors. Without this in mind, supervisors may not be aware of the consequences of their abusive behavior and may even develop an illusion that such a practice worked. Another important managerial implication of this research is that the use of contingent reward after mistreating subordinates can backfire. Supervisor abuses, followed by a contingent reward, send an inconsistent signal to the employee that creates confusion and strain. Inconsistent actions from the supervisor also produce ethical tensions that reduce customer-oriented behaviors and a company’s ability to serve the customer (Friend et al., 2020). These training programs are important methods to combat the detrimental effects of abusive supervision in the workforce.
Originality/value
This research draws on the contingent self-regulation impairment model as an overarching framework to unpack the relationship between abusive supervision and salespeople’s job performance. Integrating three research streams (i.e. abusive supervision, leadership reinforcement and retail selling), this study proposes customer orientation as a novel mechanism and sheds light on how abusive supervision interplays with contingent punishment/reward to impact salespeople’s outcomes.

Abstract
Purpose
Concerning that limited explanation exists examining the function of corporate governance in trust processing within entrepreneurial network development, the purpose of this paper is to explore trust evolution and the role of corporate governance in an entrepreneurial network.
Design/methodology/approach
This paper makes an innovative exploration based on the case study of NVC Lighting Holding Limited.
Findings
It proposes that in the initial period of network relationship which is based on entrepreneur’s individual social network and embodies sole social network embeddness, entrepreneurial network relies more on affective trust than contractual trust. When stepping into extending period of network relationship which reflects separate embeddedness of social and market network, however, entrepreneurial network has an equal reliance on both affective trust and contractual trust. With further development, when ushering in the phase of maturity which undergoes superimposing embeddedness of both social and market network, entrepreneur network inclines to rely more heavily on affective trust than contractual trust. During the whole process, it can be found that the reliance of entrepreneurial network on trust has the tendency to transfer from affective trust to contractual trust. Furthermore, decreasing of equity ratio of founders and strengthening of controlling right heterogeneity in the corporate governance have facilitated the transfer process and the entrepreneurs’ authority has restraining effect on the evolution of the process.
Originality/value
Through case study, this paper presents the trust evolution process in different stages of entrepreneurial network. Another important theoretic contribution of this paper is that it reveals the function of corporate governance in trust processing within entrepreneurial network development.

Abstract
Purpose
The purpose of this paper is to empirically analyze the effects of stock price synchronicity and herding behavior of qualified foreign institutional investors (QFII) on stock price crash risk, especially the mediating effect of herding behavior of QFII on the relation of stock price synchronicity and stock price crash risk.
Design/methodology/approach
Taking China’s A-share listed companies from 2005 to 2014 and QFII holding shares data as the research sample, this study calculates herding effect index, sock price synchronicity index and stock price crash risk index, and perform linear regression.
Findings
This study concludes that, either herding behavior of QFII or the stock price synchronicity can increase the stock price crash risk. Further study reveals that, the herding behavior of QFII also improves the effect of stock price synchronicity on stock price crash risk. Namely, herding behavior of QFII acts as the mediating role between stock price synchronicity and stock price crash risk.
Originality/value
This study empirically analyzes and verifies the mediating roles of herding behavior of QFII in affecting the relation of sock price synchronicity and stock price crash risk for the first time. The findings of this study contribute to the study of the role of QFII in stabilizing Chinese security market.

Abstract
Purpose
The purpose of this paper is to explore the mediating effect of vocational identity and the moderating effect of work values on the relation between career exploration and fit perception of Chinese new generation employees.
Design/methodology/approach
A survey was conducted to measure variables in this study. Based on review of the related studies about work value, career exploration, vocational identity and fit perception, the authors establish a theoretical model and propose hypotheses. Data were obtained from 647 Chinese post‐1980s generation employees.
Findings
According to the statistical analysis result, the paper demonstrates that career exploration can affect fit perception through mediator of vocational identity; when people have stronger preference to chase for job comfort and security, the relations between career exploration effort, vocational identity and fit perception becomes stronger; once individual has stronger preference for status and independence, the relations between career exploration effort, vocational identity and fit perception becomes weakened.
Research limitations/implications
The data used in this study only came from the employees, although the authors test homologous deviation through Harman single factor test. If the authors can conduct the survey from both employees and their supervisors, it will be better for them to avoid homology bias. Furthermore, more factors need to be considered in the formation of fit perception of Chinese new generation employees.
Originality/value
The paper explains the internal relations between work value, career exploration, vocational identity and fit perception on the basis on of the characteristics of Chinese new generation employees.

Abstract
Purpose
The purpose of this paper is to apply social network analysis (SNA) to study faculty research productivity, to identify key leaders, to study publication keywords and research areas and to visualize international collaboration patterns and analyze collaboration research fields from all Management Information System (MIS) departments in Taiwan from 1982 to 2015.
Design/methodology/approach
The authors first retrieved results encompassing about 1,766 MIS professors and their publication records between 1982 and 2015 from the Ministry of Science and Technology of Taiwan (MOST) website. Next, the authors merged these publication records with the records obtained from the Web of Science, Google Scholar, IEEE Xplore, ScienceDirect, Airiti Library and Springer Link databases. The authors further applied six network centrality equations, leadership index, exponential weighted moving average (EWMA), contribution value and k-means clustering algorithms to analyze the collaboration patterns, research productivity and publication patterns. Finally, the authors applied D3.js to visualize the faculty members' international collaborations from all MIS departments in Taiwan.
Findings
The authors have first identified important scholars or leaders in the network. The authors also see that most MIS scholars in Taiwan tend to publish their papers in the journals such as Decision Support Systems and Information and Management. The authors have further figured out the significant scholars who have actively collaborated with academics in other countries. Furthermore, the authors have recognized the universities that have frequent collaboration with other international universities. The United States, China, Canada and the United Kingdom are the countries that have the highest numbers of collaborations with Taiwanese academics. Lastly, the keywords model, system and algorithm were the most common terms used in recent years.
Originality/value
This study applied SNA to visualize international research collaboration patterns and has revealed some salient characteristics of international cooperation trends and patterns, leadership networks and influences and research productivity for faculty in Information Management departments in Taiwan from 1982 to 2015. In addition, the authors have discovered the most common keywords used in recent years.
