Abstract
Purpose
Professor independent directors have been the subject of academic debate as to whether they can improve corporate innovation performance. Accordingly, this paper aims to investigate the relationship between professor independent directors, the marketization process and corporate innovation performance in China.
Design/methodology/approach
Using a sample of Chinese A-share listed companies from 2014 to 2017, this study examines how professor independent directors and the (low and high) marketization process affect corporate innovation performance.
Findings
The empirical analysis of this yields the following main results. First, enterprises with a higher proportion of professor independent directors outperform those with a low proportion of professor independent directors in terms of corporate innovation. Second, the study of introducing the marketization process finds that there is no “market failure”. Third, while professor independent directors have a significant association with innovation performance in the high-marketization group, this association is negligible in the low-marketization group, indicating that there is no “substitution effect”.
Originality/value
This research provides empirical evidence to support the hiring of professors with relevant backgrounds as independent directors who can contribute meaningfully to corporate governance and innovation while also fostering industrial transformation. This study also identifies that the role of professor independent directors in facilitating corporate innovation is more effective in regions with a high degree of marketization than in regions with a low degree of marketization, implying that increasing marketization benefits the role of professor independent directors in facilitating corporate innovation.

Abstract
Purpose
Drawing on mood regulation theories, the purpose of this paper is to examine the impact of employees’ coworker-helping behaviors (OCB-Is) on the relationships between prior negative affect and subsequent job satisfaction and creative performance. The authors hypothesize that employees’ work competence is a moderator of the relation between negative affect and OCB-Is.
Design/methodology/approach
Data were collected by the experience sampling method of self-rating (twice per day) and coworker-rating (once per day) over two weeks by 120 administrative employees and their coworkers in a university; 743 available days were obtained.
Findings
Multilevel modeling showed that self-rated negative affect during the morning was associated with coworker-rated OCB-Is during the afternoon; OCB-Is were positively associated with self-rated job satisfaction and coworker-rated creative performance during the afternoon; based on an indirect effect, OCB-Is mediated the relationships between negative affect and job satisfaction, and negative affect and creative performance; and employees with high-level work competences tended to engage in OCB-Is more than employees with low-level work competences when experiencing negative affect.
Originality/value
These findings suggest that OCB-Is create a positive reaction by converting negative affect into positive job satisfaction and creative performance and that employees’ work competence is the boundary condition.

This paper aims to investigate the dyeability of tussah silk fabric with lotus seedpod extract as the source of nontoxic and eco-friendly dyestuffs and functional agent.
Abstract
Purpose
This paper aims to investigate the dyeability of tussah silk fabric with lotus seedpod extract as the source of nontoxic and eco-friendly dyestuffs and functional agent.
Design/methodology/approach
Mordant free dyeing method was carried out using citric acid (CA) as the cross-linking agent to link the fibre and dye molecules. First, the natural pigment of oligomeric procyanidins was extracted from the lotus seedpod and then used to dye the tussah silk fabric. After the dyeing process, the dyed samples were treated with CA solution under different concentrations to improve the colour fastness.
Findings
The tussah silk fabric was successfully coloured in reddish brown through the dyeing process and charactered by using Fourier-transform infrared spectroscopy spectrometer. Moreover, lotus seedpod extract could impart excellent UV protection ability to the dyed samples, and UPF values reached up to 2000. CA dosage influenced the colour characteristics, UV protection and anti-wrinkling performance. The optimum dosage of CA was 7% (Wt.%). In addition, dyed silk fabric showed good antibacterial activity and the calculated bacteriostatic rate against Escherichia coli and Staphylococcus aureus were 83.27 and 60.2%, respectively.
Practical implications
This bio-dyeing strategy provided a simple and effective method for sustainable tussah silk fabric dyeing process.
Originality/value
This paper provides a novel dyeing strategy for mordant free dyeing and functionalization of tussah silk fabric, with lotus seedpod extract as natural pigment and CA as cross-linking agent to link the fibre and dye molecules.

Abstract
The current challenges experienced by all nations promote the trade-off between the increase in economic performance and the protected environment. The investigation based on the energy economy has become an irreplaceable topic to determine the correct path for minimizing the trade-off cost. Within this scope, this study has been performed to investigate the causality nexus between the exports indicators (aggregated exports and the ICT exports) and the energy consumption (renewable and nonrenewable energy consumption of the selected five emerging countries. The Dumitrescu–Hurlin panel causality analysis is performed on the annual data between 2000 and 2014. As a consequence of the evidence, it is documented that there are various causality relationships between the exports and the energy consumption indicators in the light of the performed analysis at different lags. However, the role of nonrenewable energy consumption is more active in the economies of the considered countries. According to the evidence, it is recommended for the emerging countries to invest and allocate more funds to renewable energy resources to diminish the role of nonrenewable energy resources in the economy.

Abstract
Purpose
This study aims to fabricate a multifunctional electromagnetic interference (EMI) shielding composite fabric with simultaneous high-efficiency photothermal conversion and Joule heating performances.
Design/methodology/approach
A multifunctional polypyrrole (PPy) hydrogel/multiwalled carbon nanotube (MWCNT)/cotton EMI shielding composite fabric (hereafter denoted as PHMC) was prepared by loading MWCNT onto tannin-treated cotton fabric, followed by in situ crosslinking-polymerization to synthesize three-dimensional (3D) conductive networked PPy hydrogel on the surface of MWCNT-coated cotton fabric.
Findings
Benefiting from the unique interconnected 3D networked conductive structure of PPy hydrogel, the obtained PHMC exhibited a high EMI-shielding effectiveness vale of 48 dB (the absorbing electromagnetic wave accounted for 84%) within a large frequency range (8.2–12.4 GHz). Moreover, the temperature of the laminated fabric reached 54°C within 900 s under 15 V, and it required more than 100 s to return to room temperature (28.7°C). When the light intensity was adjusted to 150 mW/cm2, the PHMC temperature was about 38.2°C after lighting for 900 s, indicating high-efficiency electro-photothermal effect function.
Originality/value
This paper provides a novel strategy for designing a type of multifunctional EMI shielding composite fabric with great promise for wearable smart garments, EMI shielding and personal heating applications.

Abstract
Purpose
The purpose of this paper is to investigate the effects of nano‐titanium dioxide and nano‐silicon dioxide particles on the mechanical and antimicrobial properties of denture base resin.
Design/methodology/approach
Nano‐titanium dioxide and nano‐silicon dioxide particles were introduced to heat‐curing denture base resin to prepare composites. Electronic universal testing machine and friction tester were used to test tensile strength and frictional resistance properties of the samples prepared, respectively; also, film adhesion method was used to test the in vitro antimicrobial activity against Candida albicans and Streptococcus mutans.
Findings
Addition of nano‐titanium dioxide particles could improve the antimicrobial property of denture base resin, and addition of nano‐silicon dioxide particles could improve the tensile strength and frictional resistance of denture base resin. Mixture of the two nano‐particles, at a certain ratio, could improve the tensile strength, frictional resistance and antimicrobial property of denture base resin to a certain extent.
Practical implications
Nano‐titanium dioxide and nano‐silicon dioxide denture base resin composites were obtained. The mechanical and antimicrobial properties of the composites were improved compared to the raw denture base resin.
Originality/value
Nano‐titanium dioxide and nano‐silicon dioxide denture base resin composites with excellent performance could be obtained. Longer service life, greater hardness and clearness helped improve the patients' quality of life. Limited work with respect to the improved denture base resin was performed, which could form the theme of a future study. The outcomes of the research reported here set a new milestone in the field of denture base resin.

Abstract
Purpose
Little systematic work has been completed on the incidence of employee ownership in a Chinese context. Similar to the situation in Eastern Europe, this type of ownership was quite widespread in China, particularly during the 1990s. Based on the existing literature and available statistical data, the purpose of this paper is to identify drivers of, and barriers to, the development of employee ownership in China.
Design/methodology/approach
The scattered evidence from the literature and official statistical sources are collected and structured in a systematic analysis where the drivers and barriers for employee ownership in the transition process from plan to market are identified at three levels: society, the company and the individual.
Findings
Employee ownership developed as a transitory stage between state and private ownership; employees acquired ownership stakes as part of the privatisation of small- and medium-sized state-owned enterprises as well as collectively owned enterprises. However, in most cases the dynamics of ownership resulted in dominant ownership by managers. This trend became more noticeable at later stages of the privatisation process.
Research limitations/implications
The paper shows how policies and institutional settings at the society level are determining for the development of employee ownership.
Originality/value
The contribution of the paper is to give a general and systematic analysis of the development of employee ownership in China both based on a comprehensive literature review and by utilising existing statistical sources.

Abstract
Purpose
This paper aims to investigate the relationship between gross domestic product (GDP) by sector and energy consumption by type in 16 emerging countries.
Design/methodology/approach
The panel model was utilized taking the period 1980-2010.
Findings
The results revealed that GDP by sector and energy consumption by type are cointegrated. Moreover, the Granger causality concluded a bi-directional causal relationship between oil, natural gas and renewable energy consumption and the value of the manufacturing, industrial and services sector. Furthermore, a bi-directional causal relationship was also found between coal consumption and the value of the services sector. Furthermore, a one-way causal relationship was found from oil consumption to the value of the agriculture sector, the value of the agriculture sector to coal consumption, and coal consumption to the value of the manufacturing and the industrial sectors.
Practical implications
This study recommended that these countries should increase their renewable energy consumption to achieve their GDP growth.
Originality/value
This study is different from the previous studies, as it disaggregated the GDP into four sectors, namely, agriculture, manufacturing, industrial and the services sector. In addition, this study will disaggregate energy consumption into oil consumption, gas consumption, coal consumption and electricity consumption.

Abstract
Purpose
Even though the importance of understanding festivals from a tourism attraction development perspective has been addressed, few studies have examined the factor of brand equity in festival tourism. For that reason, this research examines the antecedents and consequents of the consumer-based brand equity (CBBE) of an event.
Design/methodology/approach
After data collection, which was carried out through a questionnaire, the structural equation model was used to analyze the statistical data. The results were based on a sample of 329 participants who attended two major music festivals in Portugal: NOS Primavera Sound and NOS Alive Portugal.
Findings
For both samples, this research shows that many aspects related to the event (image, experience and satisfaction) impact CBBE and CBBE influences destination image, the intention to revisit the destination and the intention to recommend the destination.
Originality/value
This study presents itself as innovative since it brings the CBBE of an event to the center of an investigation, showing how it helps transfer the effects of image, satisfaction and the experience of a festival to a destination image, the intention to revisit and the intention to recommend a place.
