Abstract
Purpose
This paper aims to investigate the relationship between corporate environmental, social and governance (ESG) ratings and leverage manipulation and the moderating effects of internal and external supervision.
Design/methodology/approach
The authors draw on a sample of Chinese non-financial A-share-listed firms from 2013 to 2020 to explore the effect of ESG ratings on leverage manipulation. Robustness and endogeneity tests confirm the validity of the regression results.
Findings
ESG ratings inhibit leverage manipulation by improving social reputation, information transparency and financing constraints. This effect is weakened by internal supervision, captured by the ratio of institutional investor ownership, and strengthened by external supervision, captured by the level of marketization. The effect is stronger in non-state-owned firms and firms in non-polluting industries. The governance dimension of ESG exhibits the strongest effect, with comprehensive environmental governance ratings and social governance ratings also suppressing leverage manipulation.
Practical implications
Firms should strive to cultivate environmental awareness, fulfil their social responsibilities and enhance internal governance, which may help to strengthen the firm’s sustainability orientation, mitigate opportunistic behaviours and ultimately contribute to high-quality firm development. The top managers of firms should exercise self-restraint and take the initiative to reduce leverage manipulation by establishing an appropriate governance structure and sustainable business operation system that incorporate environmental and social governance in addition to general governance.
Social implications
Policymakers and regulators should formulate unified guidelines with comprehensive criteria to improve the scope and quality of ESG information disclosure and provide specific guidance on ESG practice for firms. Investors should incorporate ESG ratings into their investment decision framework to lower their portfolio risk.
Originality/value
This study contributes to the literature in four ways. Firstly, to the best of the authors’ knowledge, it is among the first to show that high ESG ratings may mitigate firms’ opportunistic behaviours. Secondly, it identifies the governance factor of leverage manipulation from the perspective of firms’ subjective sustainability orientation. Thirdly, it demonstrates that the relationship between ESG ratings and leverage manipulation varies with the level of internal and external supervision. Finally, it highlights the importance of governance in guaranteeing the other two dimensions’ roles by decomposing overall ESG.

Abstract
Purpose
In this paper, the effects of the adhesive and curing agent contents on the tensile strength, bending strength, gas evolution and gas permeability of three-dimensional printed sand molds are studied. A strength model of the three-dimensional printed sand molds is proposed. The multi-material composite sand mold forming test is carried out. In addition, the mesostructure of the sand mold is studied.
Design/methodology/approach
The performances of three-dimensional printed sand mold such as tensile strength, bending strength, gas evolution and gas permeability are studied using the standard test methods. The mesostructure of the sand mold is studied by digital core technology.
Findings
A sand mold strength model based on the resin adhesive content, curing agent content and sand mold compactness are obtained. Two types of multi-material composite three-dimensional printed sand molds are proposed. An increase in the curing agent content in the sand mold widens the mesoscopic characteristic size distribution of the sand mold, and large-sized mesostructures appear, resulting in a decrease in the sand mold bearing capacity.
Practical implications
Process parameters that affect the performance of three-dimensional printed sand mold are revealed. The sand mold bearing curve provides a reference for the ultimate design of three-dimensional printed sand mold.
Originality/value
The paper deals with experimental work on the performance and mesostructure of multi-material composite three-dimensional printed sand mold with different contents of adhesive and curing agent. That gives a perspective on future designs of sand mold based on these principles.

Abstract
Purpose
This paper aims to determine how the viscosity and curing agent content affect the flowability of moist silica sand granules. In addition, a coating device was designed according to the flow properties of silica sand granules.
Design/methodology/approach
The flowability of silica sand granules premixed with two curing agents of different viscosities is studied using a Jenike shear apparatus. An open-ended device was used in discharge testing of sand granules with a design based on the variable dip angle of the two plates and variable outlet size.
Findings
The test results show that increasing the curing agent content would significantly decrease the flowability of silica sand granules, and a curing agent of higher viscosity has a greater effect on the flowability of silica sand. The presence of a curing agent strengthens the cohesion among sand granules, lubricates them and restrains their deformation. The shape function of the coating device was obtained by theoretical derivation.
Practical implications
The flow properties provide a valuable theoretical guidance for the design of coating device for sand mold printing.
Originality/value
This paper deals with experimental work on flow properties of silica sand granules with different viscosities and curing agent content. The shape function of a wedge-shaped coating device is obtained based on experimental data.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Practical implications
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.
Originality/value
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.

Abstract
Purpose
This study aims to solve the problem of job scheduling and multi automated guided vehicle (AGV) cooperation in intelligent manufacturing workshops.
Design/methodology/approach
In this study, an algorithm for job scheduling and cooperative work of multiple AGVs is designed. In the first part, with the goal of minimizing the total processing time and the total power consumption, the niche multi-objective evolutionary algorithm is used to determine the processing task arrangement on different machines. In the second part, AGV is called to transport workpieces, and an improved ant colony algorithm is used to generate the initial path of AGV. In the third part, to avoid path conflicts between running AGVs, the authors propose a simple priority-based waiting strategy to avoid collisions.
Findings
The experiment shows that the solution can effectively deal with job scheduling and multiple AGV operation problems in the workshop.
Originality/value
In this paper, a collaborative work algorithm is proposed, which combines the job scheduling and AGV running problem to make the research results adapt to the real job environment in the workshop.
