Abstract
Purpose
Sustainable development requires companies to achieve a long-term balance between the economic, environmental and social spheres in their development process, and is not limited to long-term commercial success. Enhancing corporate environmental, social and governance (ESG) performance plays a critical role in achieving sustainable economic and social development. The purpose of this study is to empirically examine the influence of short-selling on corporate ESG performance and unravel the mechanisms involved.
Design/methodology/approach
The authors use the data from Chinese A-share listed companies spanning from 2010 to 2021 as the research sample and conduct empirical research using mediating effect model, instrumental variables and difference-in-differences methods.
Findings
The findings suggest that short-selling has a positive impact on ESG performance, thus, contributing to the realization of sustainable development goals (SDGs) and achieving a balanced development of economy, environment and society, rather than only promoting corporate longevity. This can be attributed to short-selling’s ability to strengthen supervision constraints on firms, improve firms’ intrinsic capabilities and promote firms’ green technological innovation. Furthermore, the ESG-enhancing effects of short-selling are contingent upon the internal and external governance levels of the firms. That is, short-selling has a more significant effect on ESG performance enhancement for firms with weaker internal and external governance. The extended analysis finds that concerning firms’ market advantage, the positive impact of short-selling on ESG is more pronounced for firms with weak monopoly power and those facing intense industry competition. In addition, when examining firms’ individual characteristics, the ESG-enhancing effect of short-selling is more potent for nonstate-owned firms, those with a shorter listing history and those facing a heightened risk of resource mismatch.
Practical implications
This study provides theoretical support and empirical evidence from the perspective of short-selling to help boost corporate ESG development and improve corporate contributions to sustainable development. ESG is the concrete projection of sustainable development concept at the firm level. Good ESG performance contributes to the realization of the SDGs by influencing the strategy, operation and management of the enterprise, and promoting the enterprise to more actively create the comprehensive value of the economy, society and environment.
Social implications
The results of this study show that short-selling can significantly enhance corporate ESG performance and strengthen corporate sustainability initiatives, thereby promoting the realization of SDGs at the firm level. These findings carry substantial implications, not only foster the improvement of China’s capital market system but also provide empirical evidence from China for capital market policy-making and sustainable development practices in other emerging markets.
Originality/value
This study not only addresses the gap in studying ESG performance from the perspective of short-selling behavior but also enriches the research on the economic consequences of short-selling and enriches the literature on the determinants of ESG performance.

Abstract
Purpose
Shared leadership has received significant empirical and theoretical attention in the project management literature. However, a dearth of studies reveals how shared leadership promotes project performance. Drawing on the theory of conservation of resources, this research proposes a serial mediation model that investigates the relationship between shared leadership and project performance through team failure learning and team resilience.
Design/methodology/approach
A field study was conducted that surveyed 79 project teams in various industries (comprising 380 project team members and 79 project managers) using a multisource, time-lagged survey design.
Findings
Our findings show that shared leadership has a positive impact on project performance. More importantly, team failure learning and team resilience play sequential mediating roles in the relationship between shared leadership and project performance.
Practical implications
This research offers new ways for project managers to manage project performance effectively. Project managers are encouraged to recognize the benefits of shared leadership. To do this, they should facilitate team failure learning and improve team resilience, which serves to boost project performance.
Originality/value
This research provides a novel perspective on how shared leadership influences project performance. To the best of our knowledge, we are among the first to explore the serial mediating effects of team failure learning and team resilience on the relationship between shared leadership and project performance.

Abstract
Purpose
The surging market demand for green construction materials has brought opportunities for construction materials enterprises' greenwashing behavior (GWB). This study aims to establish the causal relationship among the influencing factors of GWB and reveal the key influencing factors from the perspective of Chinese construction materials enterprises under multi-agent interactions.
Design/methodology/approach
This study is based on stakeholder theory, resource-based theory and the green development behavior and performance of industrial enterprises (GDBP-IE). First, with the literature analysis, an index framework of the influencing factors of enterprises' GWB was constructed from five dimensions (including 15 factors): environmental regulation, public scrutiny, market environment, corporate resources and corporate green development (GD) performance. Second, the interactive relationship among influencing factors was obtained by a questionnaire survey. Finally, the data are processed and analyzed with the grey-DEMATEL (Decision-making Trial and Evaluation Laboratory) method.
Findings
Among the factors, corporate information transparency has the greatest impact on the other factors, and consumer green preferences are most influenced by others. The most critical and important factor is the corporate social performance factor. In China, corporate social performance, corporate information transparency, corporate size and media supervision are the key factors influencing the GWB of construction materials enterprises.
Originality/value
This study provides a new perspective on the literature related to GWB by considering multi-agent interactions and extends the evidence from the construction materials industry for research on the drivers or influencing factors of enterprises' bad environmental behavior. Furthermore, it adds insights from China for further research on the governance strategies of GWB in other countries.

Abstract
Purpose
This study aims to assess the oxidative stability of avocado oil (AO) at various temperatures, using butylated hydroxytoluene (BHT) as an artificial antioxidant and different concentrations of ultrasonic extract of Chlorella vulgaris.
Design/methodology/approach
Extracts of C. vulgaris were obtained using four solvents: water, acetone, ethanol and 80% ethanol-aqueous. Standard techniques were used to conduct qualitative phytochemical screening of the extracts. The extracted samples were analyzed for total phenolics, total flavonoids, antioxidant activity and phenolic compound fractionation. Some physicochemical parameters of AO treated with various concentrations of C. vulgaris ultrasonic extract compared to a 200 ppm BHT and exposed to different temperatures were measured.
Findings
The highest phenolic, flavonoids content and antioxidant activity was achieved by 80% ethanolic extract of C. vulgaris . The results showed that exposure of AO to high temperatures led to significant changes in the oil's physicochemical properties. These changes increased as the temperature increased. On the other hand, adding 80% ethanolic extract of C. vulgaris into AO reduced the effect of heat treatment on the change in physicochemical properties.
Originality/value
Adding 80% ethanolic extract of C. vulgaris into AO can potentially reduce the impact of heat treatment on the alteration of physicochemical properties.

Abstract
Purpose
A successful process of design concept evaluation has positive influence on subsequent processes. This study aims to consider the evaluation information at multiple stages and the interaction among evaluators and improve the credibility of evaluation results.
Design/methodology/approach
This paper proposes a multi-stage approach for design concept evaluation based on complex network and bounded confidence. First, a network is constructed according to the evaluation data. Depending on the consensus degree of evaluation opinions, the number of evaluation rounds is determined. Then, bounded confidence rules are applied for the modification of preference information. Last, a planning function is constructed to calculate the weight of each stage and aggregate information at multiple evaluation stages.
Findings
The results indicate that the opinions of the evaluators tend to be consistent after multiple stages of interactive adjustment, and the ordering of design concept alternatives tends to be stable with the progress of the evaluation.
Research limitations/implications
Updating preferences according to the bounded confidence rules, only the opinions within the trust threshold are considered. The attribute information of the node itself is inadequately considered.
Originality/value
This method addresses the need for considering the evaluation information at each stage and minimizes the impact of disagreements within the evaluation group on the evaluation results.

Abstract
Purpose
Research into older adults' use of social media remains limited. Driven by increasing digitalisation in China, the authors focus on Chinese older adults (aged 60–75)’ use of WeChat.
Design/methodology/approach
This study used a qualitative interpretive approach and interviewed Chinese older adults to uncover their social practices of WeChat use in everyday life.
Findings
By using social practice theory (SPT), the paper unfolds Chinese older adults' social practices of WeChat use in everyday life and reveals how they adopt and resist the drastic changes in Chinese society.
Originality/value
The study contributes to new understandings of SPT from technology use by emphasising the dynamic characteristics of its three elements. The authors synthesise both adoptions and resistance in SPT and highlight the importance of understanding three elements interdependently within specific contexts, which are conditioned by structure and agency.

Abstract
Purpose
This study aims to explore whether social entrepreneurial self-efficacy (SESE) mediates the empathetic concern (EC)–social entrepreneurial intentions (SEIs) relationship. In addition, drawing on institutional theory, the authors propose that the EC–SESE–SEI relationship is contingent upon perceptions of cultural support (PCS) towards social entrepreneurship in a society.
Design/methodology/approach
Data from 232 Taiwanese business and management undergraduates were used to test the proposed relationships.
Findings
SESE was found to mediate the relationship between EC and SEI. However, cultural support towards social entrepreneurship in society had a negative moderating effect on the EC–SESE–SEI relationship, suggesting that the EC–SESE–SEI relationship was stronger under conditions of low, rather than high PCS.
Originality/value
This paper provides further insights into not only the link between EC and SEI but also the conditions under which EC is translated into SEI. It also enhances the recent limited knowledge about how context and cultural attitudes and values towards social entrepreneurship shapes SEI.

Abstract
Purpose
Polyethylene terephthalate (PET) as a fiber molding polymer is widely used in aerospace, electrical and electronic, clothing and other fields. The purpose of this study is to improve the thermal insulation performance of polyethylene terephthalate (PET), the SiO2 aerogel/PET composites slices and fibers were prepared, and the effects of the SiO2 aerogel on the morphology, structure, crystallization property and thermal conductivity of the SiO2 aerogel/PET composites slices and their fibers were systematically investigated.
Design/methodology/approach
The mass ratio of purified terephthalic acid and ethylene glycol was selected as 1:1.5, which was premixed with Sb2O3 and the corresponding mass of SiO2 aerogel, and SiO2 aerogel/PET composites were prepared by direct esterification and in-situ polymerization. The SiO2 aerogel/PET composite fibers were prepared by melt-spinning method.
Findings
The results showed that the SiO2 aerogel was uniformly dispersed in the PET matrix. The thermal insulation coefficient of PET was significantly reduced by the addition of SiO2 aerogel, and the thermal conductivity of the 1.0 Wt.% SiO2 aerogel/PET composites was reduced by 75.74 mW/(m · K) compared to the pure PET. The thermal conductivity of the 0.8 Wt.% SiO2 aerogel/PET composite fiber was reduced by 46.06% compared to the pure PET fiber. The crystallinity and flame-retardant coefficient of the SiO2 aerogel/PET composite fibers showed an increasing trend with the addition of SiO2 aerogel.
Research limitations/implications
The SiO2 aerogel/PET composite slices and their fibers have good thermal insulation properties and exhibit good potential for application in the field of thermal insulation, such as warm clothes. In today’s society where the energy crisis is becoming increasingly serious, improving the thermal insulation performance of PET to reduce energy loss will be of great significance to alleviate the energy crisis.
Originality/value
In this study, SiO2 aerogel/PET composite slices and their fibers were prepared by an in situ polymerization process, which solved the problem of difficult dispersion of nanoparticles in the matrix and the thermal conductivity of PET significantly reduced.

Abstract
Purpose
The purpose of this study is to improve the mechanical properties, thermal insulation properties and flame retardant properties of polyethylene terephthalate (PET), the organic montmorillonite (OMMT)/SiO2 aerogel/PET composites and fibers were prepared, and the effects of the OMMT/SiO2 aerogel on the structure, thermal conductivity and flame retardance of the OMMT/SiO2 aerogel/PET composites and their fibers were systematically investigated.
Design/methodology/approach
The OMMT/SiO2 aerogel/PET composites and fibers were prepared by in-situ polymerization and melt spinning using SiO2 aerogel as thermal insulation filler and OMMT (DK2) as comodified filler.
Findings
The experimental results showed that OMMT improved the crystallization properties of PET. Compared with the crystallinity of SiO2 aerogel/PET composites (34.8%), SiO2 aerogel/PET composites and their fibers reached 45.1% and 49.2%, respectively. The breaking strength of the OMMT/SiO2 aerogel/PET composite fibers were gradually increased with the OMMT content. When the content of OMMT was 0.8 wt.%, the fracture strength of the composite fibers reached 4.40 cN/dtex, which was 54% higher than that of the SiO2 aerogel/PET fiber. In addition, the thermal insulation properties of the composites and their fibers were improved by addition of fillers, and at the same time reached the flame retardant level. The thermal conductivity of the 0.8 wt.% OMMT/SiO2 aerogel/PET composites was 101.78 mW/(m·K), which was 49.3% and 58.8% lower than that of the SiO2 aerogel/PET composites and the pure PET, respectively. The thermal conductivity of the fiber fabrics woven from the 0.8 wt.% OMMT/SiO2 aerogel/PET composites was 28.18 mW/(m·K), which was 29.0% and 44.6% lower than that of the SiO2 aerogel/PET composite fiber fabrics and PET fiber fabrics. The flame retardancy of the composites was improved, with an limiting oxygen index value of 29.2% for the 0.8 wt.% OMMT/SiO2 aerogel/PET composites, which was 4.1% higher compared to the SiO2 aerogel/PET composites, and achieved the flame retardant level.
Research limitations/implications
The SiO2 aerogel/PET composites and their fibers have good mechanical properties, flame retardant properties and thermal insulation properties, exhibited good potential for application in the field of thermal insulation, such as warm clothing. Nowadays, as the energy crisis is becoming more and more serious, it is very important to improve the thermal insulation properties of PET to reduce energy losses and mitigate the energy crisis.
Originality/value
In this study, PET based composites and their fibers with excellent mechanical properties, thermal insulation properties and flame retardant property were obtained by using three-dimensional network porous silica aerogel with low density and low thermal conductivity as the thermal insulation functional filler and two-dimensional layered OMMT as the synergetic modified filler.
