This study aims to shed new light on the effect of gift packaging shape, specifically the distinction between horizontal and vertical orientations, on the face consciousness of both gift givers and recipients. The underlying mechanism of the main effect is examined, focusing on the perception of social status symbols. In addition, downstream outcome variables were included in the study to explore the effects of gift package shape on willingness to buy (WTB) and word-of-mouth (WOM) in the giver and receiver contexts, respectively. Furthermore, these effects were repeatedly verified in both China and the USA, revealing the significance of cultural differences. The study also investigated the moderating effects of an individual’s power state (low or high power) on the giver’s face consciousness.

Six studies were conducted to address the research objectives. Study 1 compared the gift givers’ face consciousness of a gift when presented with vertical package shapes versus horizontal. Subsequently, Study 2 investigated whether consumers’ perception of social status symbols mediates the effect of gift package shape on gift givers’ face consciousness. Study 3a expanded the conceptual model to include the downstream outcome variable of WTB in the context of gift-giving. Study 3b was validated with American participants, revealing the influence of cultural background differences on face consciousness. Study 4 introduced a gift-receiving context to investigate the chain-mediated effects of gift package shapes on consumer WOM. Lastly, Study 5 critically examined the boundary effect of personal power states on the interaction between the gift givers’ face consciousness and WTB.

The results indicate that gift givers and recipients attribute higher face consciousness to gifts with vertical package shapes compared to horizontal ones. In addition, consumers’ perception of gifts as status symbols was the underlying mechanism driving the impact of gift packaging shape on face consciousness. Furthermore, the face consciousness for gift packages of vertical shape was enhanced when people were in lower-power states as opposed to higher-power states, subsequently leading to an increase in the WTB.

The research is limited to an online virtual brand study; future field studies could be conducted to enhance the authenticity of the participants’ gift-giving experience and the overall external validity of the studies. In addition, gender-based stereotypes and the relationship between the giver and the receiver (transactional or intimate) may also influence the relationship between gift package shapes and face consciousness.

The practical implications of this research focus on three points. First, gift brand managers should strategically employ vertical package shapes to signal high-end attributes and evoke face consciousness among consumers, aligning with the psychology of both givers and recipients. Second, managers must consider consumers’ power states in gift-giving scenarios, tailoring packaging recommendations to the dynamics between givers and recipients to maximize market share. Last, cultural differences in face consciousness, particularly between Asian and Western cultures, necessitate that managers adapt packaging designs to respect and enhance the social status of both givers and recipients in culturally sensitive ways. These findings underscore the importance of understanding and integrating consumer psychology, power dynamics, and cultural nuances into gift packaging strategies to boost market share.

The research contributes to understanding the impact of gift packaging shape on the perception of face consciousness among both gift givers and recipients. It highlights the mediating role of social status symbols and extends its scope by examining downstream effects such as WTB and WOM. It explores individual power states as a moderating factor, revealing how personal dynamics influence perceptions of face-saving consciousness. Also, the cross-cultural validation of these effects in China and the USA underscores the importance of considering cultural differences.

The purpose of this paper is to explore resilience strategies of Chinese street vendors in a shifted regulatory policy environment from a strength-based and entrepreneurial perspective.

Drawing upon nine in-depth interviews and naturalistic observations in an urban village of Guangzhou, China, the study empirically investigates how unregulated sidewalk-based hawkers struggle to survive against socioeconomic adversities compared with regulated vendors’ operations in a legitimate transitional market.

Mirroring a sub-group of rural-to-urban migrants, street vendors espouse subtle strategies centering on purposefulness, resourcefulness and hardiness, which are instantiated through family obligation, sales tactics, merchandising techniques, technology application, trading flexibility, moral sentiment and assistance network. As such, street entrepreneurs are both enacting and constructing resilience in response to specific challenging contexts including impoverishment, operating cost inflation, contingent loss, fierce competition, market uncertainty, intensive workloads, municipal inspection and arbitrary governance practice of village cooperative organization.

Notwithstanding its limited generalizability, the result sheds light on crystallization of street vendors’ resilience and informs social services and policy remedies.

The study provides a frame of reference to examine the interplay of resilience theory from psychology and entrepreneurship thesis from the field of business management by adding new evidence to the research on “entrepreneurial resilience” and potentially serves as a catalyst to enrich existing literature with an integrated perspective to comprehend the coping process of these necessity-driven micro-enterprise operators. The antagonistic understanding of informal economy is so predominating that it obscures structural oppression undermining social justice, whereas the spirit of self-reliance among street entrepreneurs is ought to be respected.

The purpose of this paper is to enhance the quadrotor’s capability of short-distance delivery to satisfy the large demand for quadrotor, which is used for goods distribution in huge warehouses, under time-varying payload and external wind disturbance.

A trajectory tracking controller design based on the combination of an adaptive sliding mode control (ASMC) method and the active disturbance rejection control (ADRC) technique is proposed. Besides, an inner–outer loop control system structure is adopted.

Simulation results of different trajectory tracking verify the effectiveness and robustness of the proposed tracking control method under various conditions, including parameter uncertainty and external wind disturbance. The proposed control strategy ensures that quadrotor UAV is capable of tracking linear and spiral trajectory well whether it loads or unloads goods in the presence of the external wind disturbance.

The proposed method of designing a trajectory tracking controller is based on an integral ADRC and ASMC scheme so as to deal with the trajectory tracking problem for a quadrotor with payload variation.

The control of a quadrotor unmanned aerial vehicle (UAV) is a challenging problem because of its highly nonlinear dynamics, under-actuated nature and strong cross-couplings. To solve this problem, this paper aims to propose a robust control strategy, based on a concept of active disturbance rejection control (ADRC).

The altitude/attitude dynamics of a quadrotor is reformulated into the ADRC framework. Three distinct variations of the error-based ADRC algorithms, with different structures of generalized extended state observers (GESO), are derived for the altitude/attitude trajectory-following task. The convergence of the observation part is proved based on the singular perturbation theory. Through a frequency analysis and a quantitative comparison in a simulated environment, each design is shown to have certain advantages and disadvantages in terms of tracking accuracy and robustness. The digital prototypes of the proposed controllers for quadrotor altitude and attitude control channels are designed and validated through real-time hardware-in-the-loop (HIL) co-simulation, with field-programmable gate array (FPGA) hardware.

The effects of unavailable reference time-derivatives can be estimated by the ESO and rejected through the outer control loop. The higher order ESOs demonstrate better performances, but with reductions of stability margins. Time-domain simulation analysis reveals the benefits of the proposed control structure related to classical control approach. Real-time FPGA-based HIL co-simulations validated the performances of the considered digital controllers in typical quadrotor flight scenarios.

The conducted study forms a set of practical guidelines for end-users for selecting specific ADRC design for quadrotor control depending on the given control objective and work conditions. Furthermore, the paper presents detailed procedure for the design, simulation and validation of the embedded FPGA-based quadrotor control unit.

In light of the currently available literature on error-based ADRC, a comprehensive approach is applied here, which includes the design of error-based ADRC with different GESOs, its frequency-domain and time-domain analyses using different simulation of UAV flight scenarios, as well as its FPGA-based implementation and testing on the real hardware.

The purpose of this paper is to explore self-management among informal tourism employees in urban China with the theoretical basis of Jianghu and reveal the forming process and operation mechanism of China’s urban informal organizations’ self-management.

This paper adopts process–event analysis of informal tourism photographers surrounding Guangzhou Tower. Conducting field inspection and in-depth interviews, the forming process is analyzed and typical events are captured to unveil this self-management mechanism.

The self-management of informal tourism employees in China is based on the Jianghu theory, which specifies the role, obligation and responsibility of a member. These above rely on word-of-mouth order or implicit ways to treat newcomers, realize internal communication and deal with public affairs. Brotherhood, benevolence and etiquette make up the core values of the Jianghu theory that advises strategies in dealing with different events. This self-management, based on the Jianghu theory, has not only effectively solved internal conflicts, but has also achieved the goal of social management.

Informal employees’ self-management is extremely important due to the high cost of government intervention. Through China’s urban informal tourism employees’ Jianghu-styled self-management, the paper shows that the government should not crack down on this group indiscriminately. Instead, it should, through the management agent, set up effective Jianghu rules to realize regular control over this group.

The purpose of this paper is to design a third-order linear active disturbance rejection controller (LADRC) to improve the response characteristics and robustness of the electrohydraulic servo system.

The LADRC was designed by replacing the nonlinear functions in each part of ADRC with linear functions or linear combinations, and the parameters of each part of the LADRC were connected with their bandwidth through the pole configuration method to reduce the required tuning parameters, and used an improved grey wolf optimizer to tune the LADRC parameters.

The anti-interference control simulation and experiment on the LADRC, ADRC and proportion integration differentiation (PID) were carried out to test the robustness, anti-interference ability and superiority of the designed LADRC. The simulation and experiment results showed that the LADRC control and anti-interference control had excellent performance, and because of its simple structure and fewer parameters, LADRC was easier to implement and had a better control effect and anti-interference.

For the problems of parameter perturbation, unknown interference and inaccurate model in the electrohydraulic position servo system, the designed third-order LADRC has good tracking accuracy and anti-interference, has few parameters and is conducive to promotion.

This research aims to provide a conceptual framework with the scope to assist in establishing sustainable supply chain clusters (SCCs) by providing an instrument for organisations to enhance the three sustainability dimensions in a dynamic environment.

This research proposes a conceptual framework to enhance sustainability and organisational performance through three theoretical lenses: the system theory, extended resource-based view and the dynamic capabilities (DCs) theory. This approach is carried out through a comprehensive review of the existing literature on SCCs.

Four main propositions are formulated and demonstrated using the developed framework, which expands the discussion about SCCs and their key characteristics in a dynamic environment. This is particularly relevant as it allows empirical testing of the theories in an SCC context.

It can be noted that more extensive research is needed to further understand the issues faced in establishing sustainable clusters. Drawing on the theoretical lenses to establish the framework helps to enhance the understanding and operational capabilities of sustainable SCCs during and after disruptions, such as the global disruption created by COVID-19.

This research paves the way to help organisations improve their adaptability to the dynamic business environment by emphasizing the importance of clustering and linking it to sustainability through DCs to establish a sustainable cluster.

This research aims to guide organisations' use of SCCs as tools to enhance sustainability in a dynamic environment, given that the relationship amongst supply chain cluster design characteristics (SCCDCs), DCs and sustainability remains unexplored. The combination of the three theoretical lenses in developing the proposed framework will assist in further understanding the applicability of these theories when they are considered together.

This paper investigates whether the audit fees of Chinese listed firms are associated with the share pledging practice of the firm’s controlling shareholders.

This study uses the audit pricing model to estimate the association between the share pledging of listed firms and audit fees. Cross-sectional analysis is conducted on a large sample of Chinese listed firms during the period 2004 to 2019. The authors further test the moderating effects of listing on the Main Board, state ownership and abnormal audit report lag on the association between share pledging and audit fees. The results remain robust to various endogeneity tests including two-stage least squares instrumental variable analysis, entropy balancing analysis and difference-in-difference analysis.

The study finds that audit fees are positively associated with the proportion of shares pledged by the listed firm’s controlling shareholder in China. The results also provide new evidence that the positive association between audit fees and the share pledging of controlling shareholders could be mitigated if the firm is listed on the Main Board and/or it is a state-owned enterprise. In contrast, pledged firms with abnormal audit report lag are found to have higher audit fees than their pledged counterparts without the excessively long audit delay.

Findings of this study have important practical implications to those charged with governance, as boards need to comprehensively understand the adverse consequences of share pledging when pursuing it as the firm’s major source of financing. The study also has policy implications for stock market regulators such as the China Securities Regulatory Commission in China. Regulators could consider developing a threshold-based share pledging disclosure and pledge ratio requirements based on factors such as a firm’s listing status and ownership structure.

This study provides new evidence on the audit-related consequences of share pledging in a significant capital market. Findings of this study also enrich the existing audit literature by introducing the share pledging activities of controlling shareholders into the audit pricing decision-making model.

This paper aims to study the synergistic lubrication effects of Sn–Ag–Cu and MXene–Ti₃C₂ to improve the tribological properties of M50 bearing steel with microporous channels.

M50 matrix self-lubricating composites (MMSC) were designed and prepared by filling Sn–Ag–Cu and MXene–Ti₃C₂ in the microporous channels of M50 bearing steel. The tribology performance testing of as-prepared samples was executed with a multifunction tribometer. The optimum hole size and lubricant content, as well as self-lubricating mechanism of MMSC, were studied.

The tribological properties of MMSC are strongly dependent on the synergistic lubrication effect of MXene–Ti₃C₂ and Sn–Ag–Cu. When the hole size of microchannel is 1 mm and the content of MXene–Ti₃C₂ in mixed lubricant is 4 wt.%, MMSC shows the lowest friction coefficient and wear rate. The Sn–Ag–Cu and MXene–Ti₃C₂ are extruded from the microporous channels and spread to the friction interface, and a relatively complete lubricating film is formed at the friction interface. Meanwhile, the synergistic lubrication of Sn–Ag–Cu and MXene–Ti₃C₂ can improve the stability of the lubricating film, thus the excellent tribological property of MMSC is obtained.

The results help in deep understanding of the synergistic lubrication effects of Sn–Ag–Cu and MXene–Ti₃C₂ on the tribological properties of M50 bearing steel. This work also provides a useful reference for the tribological design of mechanical components by combining surface texture with solid lubrication.

The sudden arrival of Covid-19 severely disrupted the supply chain of personal protective equipment (PPE) in Australia. This paper aims to examine the development of a geographical cluster, which, through the application of additive manufacturing (AM), responded to the PPE supply crisis.

This longitudinal case study focuses on an AM cluster, which was developed to supply PPE in a responsive and flexible manner from 2019/2020. The study gathered data over three stages of cluster evolution: pre, during and post-peak Covid-19.

The type and nature of exchanges between organizations involved in the cluster established important insights into success factors for cluster creation and development. Using an established complexity framework, this study identifies the characteristics of establishing a cluster. The importance of cluster alignment created initially by a common PPE supply goal led to an emerging commercial and relational imperative to address the longer-term configuration after the disruption.

Clusters can be a viable option for a technology-driven sector when there is a “buzz” that drives and rapidly diffuses knowledge to support cluster formation. This research identifies the structural, socio-political and emergent dimensions, which need to be considered by stakeholders when aiming at improving competitiveness using clusters.

Covid-19 has rapidly and unexpectedly disrupted the supply chain for many industries. Responding to challenges, businesses will investigate different pathways to improve the overall resilience including on-/near-shoring. The results provide insights into how clusters are formed, grow and develop and the differentiating factors that result in successful impacts of clusters on local economies.
