Abstract
Purpose
The purpose of this study is to provide effective and environmental-friendly corrosion inhibitors derived from graphene oxide for Q235 steel.
Design/methodology/approach
Nontoxic and environment-friendly 4-aminobenzoic acid was used to functionalize graphene oxide via amidation and diazotization. The obtained amidation 4-aminobenzoic acid functionalized graphene oxide (PAGO) and diazotization 4-aminobenzoic acid functionalized graphene oxide (PDGO) were characterized by FTIR, Raman and TEM, while the inhibition efficiencies were analyzed by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP). Furthermore, theoretical inhibition efficiencies were investigated by density functional theory (DFT) approach.
Findings
At a concentration of 40 ppm, the maximum inhibition efficiency of PAGO and PDGO were 97.90% and 96.72% in EIS measurement, respectively, which were in accordance with PDP data. Moreover, experimental results were supported by DFT-based quantum chemical calculation.
Originality/value
Environmental-friendly PAGO and PDGO were synthesized successfully. The synthetic inhibitors exhibited excellent inhibition efficiencies in EIS and PDP measurements. Furthermore, a computational study using DFT supported the trend that PAGO was better inhibitor than PDGO.

Abstract
Purpose
The purpose of this paper is to address several challenges faced by organizational management in the contemporary context, and how managers can better reply to management challenges by integrating oriental and occidental philosophy and wisdom.
Design/methodology/approach
The paper first describes the characteristics of the contemporary management context and identifies challenges that managers are likely to encounter. The paper then investigates how oriental and occidental philosophy and wisdom reply to these management challenges, whilst also considering the relative advantages and disadvantages of both traditions. Based on the complementarity of these two traditions, the paper finally proposes a framework that integrates both oriental and occidental wisdom by HeXie Management Theory to better respond to management challenges.
Findings
The contemporary organizational environment is characterized by four key salient components: complexity, change, ambiguity, and uncertainty (CCAU). Managers are challenged by problems of determining causality, managing holistically, and adaptation to rapid change. Western philosophical approaches to confronting management challenges arising from CCAU, inherent in the wider economic environment, emphasize standardization and rational design on the basis of science, law, and religion. Conversely, Oriental philosophical approaches to management challenges oppose such rigid systems in favour of flexibility and adaptability which emphasize harmony and morality. Essentially, whereas western thought intends to limit the occurrence of unpredicted events through the development of scientific systems, oriental thinking aims to provide a flexible and fluid system which absorbs the effects of CCAU, thus limiting and using its impact. These two perspectives both have their own advantages and disadvantages when facing management challenges in the context of CCAU. By integrating these two complementary approaches, the authors propose HeXie Management Theory (HXMT). HXMT establishes a clear vision and mission to direct the development of organizations; to organize an integrated management system through the HeXie Theme and HeXie Coupling, and to apply the component “He Principle” and “Xie Principle” as basic mechanisms to cope with management challenges.
Originality/value
This study contributes to research on relationships between organizations and environment by providing a holistic analysis, and adds knowledge about how to reply to management challenges by constructing ambidextrous organizations based on HeXie Management Theory.

Abstract
Purpose
Traditional ion optics manufacturing processes are complex and costly. The purpose of this paper is to study the feasibility of using selective laser melting (SLM) to produce additively manufactured ion optics.
Design/methodology/approach
An SLM machine was used to generate Ti6Al4V screen grids. The output was separated through wire cutting from the build platform and studied through a scanning electron microscope. To increase the geometrical accuracy of the original grid, samples consisting of nine-aperture arrays were fabricated with different parameter combinations, increasing the energy density. An empirical method to correlate the energy density applied in the fabrication process with the dimensional accuracy of the hole array positioning was developed through the analysis of multiple samples.
Findings
The SLM machine generated grids with optimal microstructure, the apertures fell within the specified tolerances and tolerances of slightly less than 10 µm can be guaranteed for the hole array positioning. The grids’ upper surfaces presented good-quality surface finish, and the lower surface quality was acceptable when the wire cutting process that separated the grid from the build platform performed slowly. Regardless of the build strategy, the stresses generated in the separation process caused the warping of the ion optic, so a flattening operation was necessary in all cases.
Originality/value
This research proved that SLM is a viable solution for ion optics fabrication, faster (less than 24 h) and less expensive (order of US$300) than traditional fabrication methods (with fabrication times from 24 to more than 400 h and costs from US$500 to US$5,000, depending on the material, size and shape).

Abstract
Purpose
The purpose of this paper is to interpret organizational change from a co-evolutionary perspective. It examines the co-evolution between institutional environments and organizational change with the mediating role of uncertainty as perceived by managers.
Design/methodology/approach
The author employed an inductive case study to explore how institutional environments interact with organizational change in a novel context: a Chinese state-owned enterprise.
Findings
The author developed a co-evolutionary model of organizational change that emphasizes the interaction between institutional-level factors and organizational-level change as bridged by top management perceptions of uncertainty. The model also illustrates the dynamics of organizational uncertainty and its effects on organizational change.
Practical implications
The study implies that uncertainty may not be an inevitable negative influence on organizational development, and tell managers how to manages the dynamics of uncertainty through two principles.
Originality/value
This study contributes to the organizational change literature by interpreting organizational change as the results of interaction between multi-level factors from institutional, organizational, and team levels. The author also expand the understanding of uncertainty from a dynamic perspective.

Abstract
Purpose
This paper is a follow‐up to the authors' first introductive article on the emerging He‐Xie management theory (HXMT), aiming to help readers better understand the concept of He‐Xie as well as the value of HXMT through several selected cases. The purpose of this paper is to illustrate the value of HXMT in helping achieve the objectives of an ambidextrous organization in harmony.
Design/methodology/approach
The potential value and explaining power of HXMT in helping achieve effective management in organizations is explored through three diversified cases in Chinese contexts. The research is implemented through analyzing the three core constructs of HXMT, i.e. HeXie theme (HT), He principle (HP) and Xie principle (XP) and HeXie coupling (HC), as well as the consistence and alignment of them in the three cases.
Findings
In all cases, the authors found the existence of HC throughout various organizational development stages. In various organizational contexts, HT could be observed in guiding managerial activities. Through identifying periodically emerging important HT and taking related activities by following the principles of XP (reflecting optimization‐oriented activities for efficiency in practice) and HP (reflecting uncertainty‐reducing activities for efficacy in practice) accordingly, organizations could reorient themselves to avoid rigidity and organizational sclerosis on the one hand and accommodate changing environmental conditions on the other. The value of HXMT is embodied in its ambidexterity capability on applying HP and XP interactively across various organizational contexts.
Originality/value
The acceptance of the emerging HXMT in a wider scope must be grounded on an appropriate understanding of its value. This paper analyses retrospectively the management practices of some very different kinds of organizations towards the objective of harmony in organization. The authors' analysis could inspire managers to consider applying HXMT in their management practice towards an ambidextrous organization in harmony.

Abstract
Purpose
The purpose of the paper is to explore Chinese women entrepreneurs’ perceptions of governance within the Shanghai fashion entrepreneurial ecosystem (SFEE) and identify whether policy is effective and inclusive of women entrepreneurs, potential barriers and if implementation is proceeding as planned.
Design/methodology/approach
We used an adaptive qualitative method incorporating a traditional case study utilizing a thematic analysis with a feminist approach to policy analysis. The case study is based on original data from ethnographic practices with a purposive sample of 15 fashion entrepreneurs and triangulated with six political elites within the SFEE.
Findings
The findings indicate that women fashion entrepreneurs perceive effective governance of the SFEE, legitimizing top-down policies and resources as the “right time” for them to be women and entrepreneurs in Shanghai. Entrepreneurs claim “I am human,” asserting gender equality in business but with circumstantial gender roles that can limit access to important resources.
Research limitations/implications
A single industry, the SFEE, limits the generalizability of the findings. Additionally, did the respondents feel comfortable with the truth? True to communist nations, citizens have few opportunities to voice opinions and public dissent is discouraged. However, we took steps to protect anonymity and excluded potentially sensitive questions dealing with geopolitical strife.
Practical implications
The study outlined six SFEE governance challenges and feminist policy responses that will strengthen the future of women’s entrepreneurship. The study can introduce classroom discussions on gender dynamics and entrepreneurship in the global context. This can help students understand the unique challenges women face, such as access to funding, networking opportunities and societal expectations, and how these factors influence the global supply chain.
Originality/value
The case study has several contributions, including a novel entrepreneurial ecosystem (EE) governance framework and the first study to endorse the voice of Chinese women entrepreneurs operating within the Shanghai fashion industry. Further, we contextualize entrepreneurship using anthropological methods. Lastly, the analysis and understanding of SFEE policies have the potential to improve women’s lives, their families and communities.

Abstract
Purpose
A dynamic model of the brake system considering the tangential and radial motion of the pad, and the torsion and wobbling motion of the disk is established in this paper. The influence of radial stiffness on the brake system is investigated under different tribological conditions. This paper aims to prove that sufficient radial stiffness is indispensable in the design of the brake system with good tribological performance.
Design/methodology/approach
By using the lumped mass method, a dynamic model of the brake system is established. A Stribeck-type friction model is applied to this model to correlate the frictional velocity, pressure and friction force. The stability of pad vibration is analysed by analysis methods. A new stability evaluation parameter is proposed to study the influence of radial stiffness on stability of pad vibration in a certain friction coefficient brake pressure range.
Findings
The findings show that the tangential vibration of the pad transits from periodic motion to quasi-periodic motion under a low tangential stiffness. The influence of radial stiffness on motion stability is stronger under a low nominal brake radius. The stability of the brake system can be ensured when the brake radius and radial stiffness are sufficient.
Originality/value
The influence of tangential stiffness of pad on stability of the brake system has been researched for decades. The insufficiency of stiffness in radial direction may also generate certain levels of instabilities but has not been fully investigated by modelling approach. This paper reveals that this parameter is also strongly correlated to nonlinear vibration of the brake pad.

Abstract
Purpose
In China, having a home before getting married is viewed as being a crucial indicator of the sincerity of romance. Despite recent increases in housing costs, men who have their homes ready for marriage stand out in the marriage market. This study aims to explore the association between readiness to marry, marriage age and the home that men purchase prior to marriage using the China Labor-force Dynamics Survey, the first countrywide follow-up survey with the theme of labor force.
Design/methodology/approach
The authors suggest new standards for determining the marital residence. In addition, contrary to the existing literature, which focuses on “Sheng Nu” (women who do not marry by the traditional marriage age in China), the authors focus on “Sheng Nan” (men who do not marry by the traditional marriage age in China).
Findings
The results show that men who own a house before marriage are reluctant to get married. The authors document robust evidence that the preexistence of the marital house decreases the willingness to marry and postpones the marriage date, regardless of location and time.
Originality/value
The authors document robust evidence that the preexistence of the marital house decreases the willingness to marry and postpones the marriage date, regardless of location and time.

Abstract
Purpose
In the digital era, creativity is pivotal in marketing, particularly in advertising, where mobile short-video advertising (MSA) has surged in popularity. However, the mechanism of how advertising creativity influences consumer decision-making remains understudied. We scrutinize how MSAs’ creativity influences consumers' purchase and sharing intentions.
Design/methodology/approach
This study uses 40 selected creative MSAs to collect a total of 666 valid questionnaires.
Findings
The results show that the exertion of creativity in MSAs positively impacts consumer intentions through perceived surprises and mental simulation, with the optimal stimulus level moderating these effects.
Practical implications
Our findings provide practical recommendations for brands and advertisers, mainly in terms of the impact of advertising creativity on advertising content strategy, helping them to create effective advertising to capture market and traffic by focusing on the content (relevance) and format (novelty) of advertising.
Originality/value
This study conducted in-depth research using the cognitive-affective-behavior (CAB) paradigm, integrated with mental simulation theory and the optimum stimulation level theory. Innovatively, we developed a model of the consumer decision-making process based on creativity, which enhances the research on the mechanisms underlying the consumer decision-making process.

Abstract
Purpose
This paper aims to identify how house price affects household consumption.
Design/methodology/approach
The authors use a micro-level data set that tracks the house price and consumption of a vast number of households over a period of four years. OLS regression is the main econometric method.
Findings
The authors document robust evidence that an increase in house prices stimulates household consumption, regardless of whether a household owns or rents. Moreover, the authors find that both acquiring and losing homeownership negatively affects household consumption. Further investigation suggests significant regional heterogeneity in the relationship between house prices and household consumption.
Originality/value
This is one of the first studies examining the relationship between house price and household consumption in China using micro-level data. Given the uniqueness of the Chinese housing market and China’s fast-growing consumption rate, the study contributes new evidence to the long-lasting debate.
