Abstract

Purpose

Based on institutional theory, this paper aims to examine whether, and if so which, institutional forces influence the quality of China’s listed financial institutions’ (FIs) sustainability disclosures.

Design/methodology/approach

Using univariate statistical and multiple regression analyses, this study quantitatively examines the impacts of coercive pressure from the government and stock exchanges, imitation within subsectors and normative pressure from industry associations and regulators on the quality of China’s listed FIs’ sustainability disclosures. Assessment of the robustness of regression results uses panel random-effects and generalized methods of moments estimation.

Findings

Financial sector corporate social responsibility (CSR) disclosure quality did not increase dramatically following issue of the “Guiding Opinions on Establishing a Green Finance System.” However, a convergence in quality is found over time. State ownership concentration and state links to dominant shareholders negatively impact the quality of financial sector sustainability disclosures, whereas stock exchange index listing requirements and industry association reporting guidance have positive influences.

Research limitations/implications

First, data availability limits the sample to listed financial firms with RKS quality scores. Thus, results may not be generalizable to the broader listed and unlisted financial sector. Second, this study only examines the influence of external forces based on institutional theory. However, internal institutional forces, such as corporate governance, may require examination. This study’s results indicate that coercive pressure, as represented by issue of the “Green Finance” policy, has not yet prompted the financial sector to improve reporting quality; however, normative pressure has had significant influence in influencing FIs’ CSR practices, with China’s banks potentially taking a leading role.

Originality/value

The financial sector has a lower direct environmental impact than traditional polluting industries and different operating and reporting structures, features often used to argue for its exclusion in prior studies. However, its indirect environmental impact via lending and investing activities is significant, suggesting evidence on the determinants of sustainability disclosure quality is required. This study uses evidence from China’s financial sector to reduce this gap in the literature.

This study aims to investigate the effects of graphite-MoS2 composite solid lubricant on the tribological properties of copper-based bearing materials under dry conditions.

Abstract

Purpose

This study aims to investigate the effects of graphite-MoS2 composite solid lubricant on the tribological properties of copper-based bearing materials under dry conditions.

Design/methodology/approach

The mixture of Graphite-MoS2 was inlaid in ZQSn6-6–3 tin bronze and ZQAl9-4 aluminum bronze matrix. These copper-embedded self-lubricating bearing materials were considered in friction pairs with 2Cr13 stainless steel, and their tribological properties were studied by using an MM200 wear test machine.

Findings

The results show that the friction coefficients and wear rates of copper-embedded self-lubricating bearing materials are lower than those of the ordinary copper-based bearing materials. The wear performance of the tin bronze inlaid self-lubricating bearing material is better than that of the aluminum bronze inlaid self-lubricating bearing material. The wear mechanism of the tin bronze bearing material is mainly adhesive wear, and that of the aluminum bronze bearing material is mainly grinding wear, oxidation wear and adhesive wear. The copper-embedded self-lubricating bearing materials had no obvious abrasion, whereas the aluminum bronze inlaid self-lubricating bearing material exhibited deep furrows and obvious abrasion under high loads.

Originality/value

These results are helpful for the application of copper-embedded self-lubricating bearing materials.

Abstract

Purpose

This paper aims to examine the voluntary disclosure practices of family and non-family listed firms and whether family firms have improved their disclosure practices following the introduction of the Principles of Good Corporate Governance and Best Practice Recommendations in 2003 in Australia.

Design/methodology/approach

Voluntary disclosures are measured by constructing an index specifically for this study. Such indexes consist of corporate governance disclosure, strategic disclosure and future disclosures. They are then regressed on firm-specific variables while controlling for family and non-family firms. A total of 60 family firms and 60 non-family firms in Australia are randomly chosen from 2001 to 2006 for examining their disclosure practices.

Findings

The research findings show that family firms disclose information voluntarily to signal to the market regarding their growth potentials and abide by government regulations to improve their reputation. Despite the fact that compliance with the Principles of Good Corporate Governance and Best Practice Recommendations was not compulsory, this paper finds that the recommendation encouraged family and non-family firms to disclose more corporate governance information.

Practical implications

The findings from this research will help investors and regulators make more strategic decisions on investments and regulations respectively in family firms.

Originality/value

There has been limited empirical evidence on the disclosure practices and their determinants of family firms in Australia. The study will thus significantly contribute to the current knowledge in this regard.

Abstract

Purpose

Drawing on the signaling theory and the relational exchange theory, this study investigates how buyer–supplier trust is influenced through the congruence and incongruence between blockchain and norm of solidarity. The moderating role of technology uncertainty is further examined.

Design/methodology/approach

Using a survey data of 110 Chinese firms, this study empirically tests not only the combined effect of blockchain and norm of solidarity on trust, but also how this combined effect is moderated by technology uncertainty. The proposed hypotheses are tested using the polynomial regression analysis and the response surface methodology.

Findings

The results suggest that trust increases along with an increasing congruence between blockchain and norm or solidarity, but in a diminishing rate (i.e. an inverted U-shaped relationship). Simultaneously, incongruence between blockchain and norm of solidarity can also guarantee sufficient trust (i.e. a U-shaped relationship). Moreover, technology uncertainty overturns the inverted U-shaped relationship between blockchain and norm of solidarity congruence on trust into a U-shaped relationship and nullifies the U-shaped relationship between blockchain and norm of solidarity incongruence on trust.

Originality/value

This study enriches supply chain governance literature by introducing the emerging blockchain governance and examining the blockchain governance's interplay with a conventional relational norm. The study emphasizes that the combined effects of these two are quite complex. Blockchain and norm of solidarity can offset each other’s limitations when both are at low to moderate levels. But simultaneous pursuit of both high blockchain and norm has only limited marginal benefits. Furthermore, the study also highlights the importance of technology uncertainty under which the combined effects between the two governance mechanisms vary. Collectively, the results provide nuanced insights into the design of supply chain governance portfolios in the digital era.

This paper aims to study the effects of MnO2 on the ZnO–Bi2O3-based varistor prepared via flash sintering (FS)

Abstract

Purpose

This paper aims to study the effects of MnO2 on the ZnO–Bi2O3-based varistor prepared via flash sintering (FS)

Design/methodology/approach

MnO2-doped ZnO–Bi2O3-based varistors were successfully prepared by the FS with a step-wise increase of the .current in 60 s at the furnace temperature <750°C under the direct current electric field of 300 V cm−1. The FS process, microstructure and the electrical performance of ZnO–Bi2O3-based varistors were systematically investigated.

Findings

The doping of MnO2 significantly decreased the onset temperature of FS and improved the electrical performance of FS ZnO varistor ceramic. The sample with 0.5 mol% MnO2 doping shows the highest improvement, with the nonlinear coefficient of 18, the leakage current of 16.82 µA, the threshold voltage of 459 V/mm and the dielectric constant of 1,221 at 1 kHz.

Originality/value

FS is a wonderful technology to enhance ZnO varistors for its low energy consumption, and a short sintering time can reduce grain growth and inhabit Bi2O3 volatilize, yet few research studies work on that. In this research, the authors analyzed the FS process and improved the electrical characteristics through MnO2 doping.

Abstract

Purpose

The purpose of this paper on the one hand is to reduce the sintering temperature, shorten the sintering time and improve the electrical properties of the sample through the two-step flash sintering method and on the other hand is to study the effect of electric field on the phase structure, microstructure and electrical properties of the flash sintering sample.

Design/methodology/approach

In this paper, (Mg1/3Ta2/3)0.01Ti0.99O2 giant dielectric ceramics were prepared by conventional sintering and two-step flash sintering, respectively. Further, the effect of electric field (600–750 V/cm) on the electrical properties of (Mg1/3Ta2/3)0.01Ti0.99O2 giant dielectric ceramics was studied.

Findings

The results show that compared with the conventional sintering, the sintering temperature of the two-step flash sintering can be reduced by 200°C and the sintering time can be shortened by 12 times. All sintered samples were single rutile TiO2 structure. Compared with conventional sintering, two-step flash sintering samples have finer grain size. The two-step flash sintered sample has similar dielectric properties to the conventional sintered sample. The dielectric constant of flash sintered samples decreases with the increase of electric field. When the electric field is 700 V/cm, the ceramic sample has the optimal dielectric properties, where the dielectric constant is approximately 5.5 × 103 and the dielectric loss is about 0.18 at 1 kHz. Impedance spectroscopy analysis shows that the excellent dielectric properties are attributed to the internal barrier layer capacitance model.

Originality/value

This paper not only provides a new method for the preparation of co-doped TiO2 giant dielectric ceramics but also has great potential in greatly improving efficiency and saving energy.

Abstract

Purpose

The purpose of this paper is to examine the relationship between accounting conservatism, corporate governance and political connection in listed firms in Malaysia where political influence plays a significant role in the capital market and in many business dealings.

Design/methodology/approach

By utilizing 824 firm-year observations comprising large listed companies over a period of four years from 2004, this study uses ordinary least squares regression models to investigate the relationship between accounting conservatism, corporate governance and political connections in Malaysia. Multiple measures of conservatism developed by Basu (1997) and Khan and Watts (2009) are employed.

Findings

The results show evidence of accounting conservatism (bad news being recognized earlier than good news) in Malaysia. Further, the results reveal that better corporate governance structure in terms of board independence is positively associated with accounting conservatism while management ownership is negatively associated with it. However, political connection has a negative moderating effect on the positive relationship between accounting conservatism and board independence. The results also suggest political connections have a positive association with firm’s future performance.

Originality/value

This study is the first in investigating the effect of political connections on accounting conservatism in Malaysian context and how political connections negatively affect the monitoring role of the corporate boards. By directly measuring political connection and controlling for various corporate governance mechanisms and firm-specific attributes, this study contributes to enhance the authors’ understanding of the political influence in financial reporting quality and firm performance in an emerging market setting.

This paper aims to focus on the variable stick force-displacement (SFD) gradience in the active side stick (ASS) servo system for the civil aircraft.

Abstract

Purpose

This paper aims to focus on the variable stick force-displacement (SFD) gradience in the active side stick (ASS) servo system for the civil aircraft.

Design/methodology/approach

The problem of variable SFD gradience was introduced first, followed by the analysis of its impact on the ASS servo system. To solve this problem, a linear-parameter-varying (LPV) control approach was suggested to process the variable gradience of the SFD. A H robust control method was proposed to deal with the external disturbance.

Findings

To validate the algorithm performance, a linear time-variant system was calculated to be used to worst cases and the SFD gradience was set to linear and non-linear variation to test the algorithm, and some typical examples of pitch angle and side-slip angle tracking control for a large civil aircraft were also used to verify the algorithm. The results showed that the LPV control method had less settling time and less steady tracking errors than H control, even in the variable SFD case.

Practical implications

This paper presented an ASS servo system using the LPV control method to solve the problem caused by the variable SFD gradience. The motor torque command was calculated by pressure and position feedback without additional hardware support. It was more useful for the electronic hydraulic servo actuator.

Originality/value

This was the research paper that analyzed the impact of the variable SFD gradience in the ASS servo system and presented an LPV control method to solve it. It was applicable for the SFD gradience changing in the linear and non-linear cases.

Abstract

Purpose

This paper aims to improve performance prediction and to acquire more detailed flow structures so as to analyze the turbulence in complex rotor-stator flow.

Design/methodology/approach

Hydraulic retarder as typical fluid machinery was numerically investigated by using hybrid Reynolds-averaged Navier–Stokes (RANS)/large eddy simulation (LES) models CIDDES Algebraic Wall-Modeled Large Eddy Simulation (LES) (WMLES) S-Ω and dynamic hybrid RANS/LES (DHRL). The prediction results were compared and analyzed with a RANS model shear stress transport (SST) k-omega which was a recommended choice in engineering.

Findings

The numerical results were verified by experiment and indicated that the predicted values for three hybrid turbulence models were more accurate. Then, the transient flow field was further analyzed visually in terms of turbulence statistics, Reynolds number, pressure-streamline, vortex structure and eddy viscosity ratio. The results indicated that HRL approaches could capture unsteady flow phenomena.

Practical implications

This study achieves both in performance prediction improvement and better flow mechanism understanding. The computational fluid dynamics (CFD) could be used instead of flow visualization to a certain extent. The improved CFD method, the fine computational grid and the reasonable simulation settings jointly enhance the application of CFD in the rotor-stator flow.

Originality/value

The improvement was quite encouraging compared with the reported literatures, contributing to the CFD playing a more important role in the flow machinery. DHRL provided the detailed explanation of flow transport between rotor and stator, which was not reported before. Through it, the flow mechanism can be better understood.

Abstract

Purpose

Mitigating the energy trilemma (ET) is of great importance for dealing with climate change and realizing carbon neutrality. To this end, effectively assessing the level of the ET is essential. The purpose of this study is to evaluate the current situation and the spatio-temporal changes of the ET in the whole of China.

Design/methodology/approach

Moreover, based on provincial-level data in China for the period 2002–2017, and by using the dynamic estimation model, we aim to determine the specific marginal impacts of smart transportation (ST) on the ET, and the possible channels through which ST works on the ET.

Findings

We thus present the following findings: (1) The performance of both ET and its three pillars is gradually improving in China. Moreover, the situation tends to vary dramatically among various regions and provinces, and the gap between the best performers and the worst is large. (2) ST plays a significant role in inhibiting the ET, a finding that remains robust after a series of tests. And (3) the ET eradication effect of ST is caused mainly by improved innovation, advanced technical efficiency, and the increasing energy scale.

Originality/value

Accordingly, we put forward some policy recommendations to help tackle ET and accelerate ST in China.
