Abstract

Purpose

The assembly sequence in the product assembly process has effect on the final product quality. To solve the assembly sequence optimization problem, such as rotor blade assembly sequence optimization, this paper proposes a small world networks-based genetic algorithm (SWN_GA) to solve the assembly sequence optimization problem. The proposed approach SWN_GA consists of a combination between the standard Genetic Algorithm and the NW Small World Networks.

Design/methodology/approach

The selection operation and the crossover operation are improved in this paper. The selection operation remains the elite individuals that have greater fitness than average fitness and reselects the individuals that have smaller fitness than average fitness. The crossover operation combines the NW Small World Networks to select the crossover individuals and calculate the crossover probability.

Findings

In this paper, SWN_GA is used to optimize the assembly sequence of steam turbine rotor blades, and the SWN_GA was compared with standard GA and PSO algorithm in a simulation experiment. The simulation results show that SWN_GA cannot only find a better assembly sequence which have lower rotor imbalance, but also has a faster convergence rate.

Originality/value

Finally, an experiment about the assembly of a steam turbine rotor is conducted, and SWN_GA is applied to optimize the blades assembly sequence. The feasibility and effectiveness of SWN_GA are verified through the experimental result.

Abstract

Purpose

With the analysis of the causes of corruption, this study aims to investigate specific anti-corruption measures that can be implemented to reform the political system and the social climate of China.

Design/methodology/approach

This study examines 97 severe corruption cases of high-ranking officials in China, which occurred between 2012 and 2015. As this insinuates that both institutional and social corruption are major problems in China, the analysis delves into multiple facts of corruption, including different types, four primary underlying causes, and suggestions regarding the implementation of three significant governmental shifts that focus on investigation, prevention tactics and legal regulations.

Findings

China’s corruption is not only individual-based but also it has developed into institutional corruption and social corruption. Besides human nature and instinct, the causes of corruption can be organised into four categories, namely, social customs, social transitions, institutional designs and institutional operations. For the removed high-ranking officials, the formation of interest chains was an important underlying cause behind their corruption.

Originality/value

This study makes a significant contribution to the literature because this study provides a well-rounded approach to a complex issue by highlighting the significance of democracy and the rule of law as ways to regulate human behaviour to combat future corruption.

This paper attempts to extend classic absolute degree of grey incidence so that the extended model can be used for grey number sequences.

Abstract

Purpose

This paper attempts to extend classic absolute degree of grey incidence so that the extended model can be used for grey number sequences.

Design/methodology/approach

The classic absolute degree of grey incidence was extended according to basic principles of grey incidence analysis. First, modelling methods and theories of the classic grey incidences were summarized. Then, the zeroing starting operator in grey incidence was extended for grey sequence. Third, the parameters in classic incidence degree were redefined, and an absolute degree of grey incidence for grey number sequences was proposed. The degree can not only be applied to grey number sequence, but also contains the uncertain information of analysis result. Fourth, two non‐linear programming models were constructed to estimate the grey coverage interval of absolute degree of incidences. Finally, the comparison method of grey numbers was introduced for sorting the different absolute degrees of incidences.

Findings

A theoretically feasible absolute degree of grey incidence was constructed for grey sequence. A case study showed that the proposed incidence degree was an effective method for grey sequence incidence analysis.

Practical implications

The method exposed in the paper can be used for grey sequences clustering, grey decision making, multi‐attribute decision making theory, uncertain target recognition and other related fields.

Originality/value

The paper succeeded in establishing an incidence analysis model for grey sequences which was still a research gap in grey system theory.

Abstract

Polymeric coatings and packaging are often used to enhance the temperature sensitivity of fiber Bragg grating temperature sensors. The high thermal expansion coefficient of the polymer enhances the thermal sensitivity by improving the wavelength shift due to thermal expansion. The adhesion of the polymeric coatings to the silica based optical fiber plays an important role in the wavelength response characteristics of fiber Bragg gratings with respect to temperature. Experiments are done to qualitatively analyze the influence of adhesion. Three‐dimensional finite element simulations have been carried out. Spring elements are used to interconnect the nodes of the meshed models of optical fiber and coating. The effect of adhesion is studied as a function of spring stiffness.

Abstract

Purpose

This study investigates both direct and moderation effects of two dimensions of contract control and information technology governance on platform participants' financial performance.

Design/methodology/approach

Using data collected from 384 platform participants from China's two largest digital platforms, hierarchical regression is used to validate the conceptual model and hypotheses.

Findings

The empirical results show that contract completeness and information technology governance independently improved financial performance, while contract enforcement had an inverted U-shaped effect on financial performance. Furthermore, information technology governance amplified the positive effect of contract completeness, but not of contract enforcement, on financial performance.

Originality/value

This study advances the literature on partnership control by showing the interactive role of information technology governance and contract control. It also enriches research on information technology usage by revealing how information technology governance benefits business partnerships. Finally, it extends transaction cost theory by demonstrating that different dimensions of contracts have different effects on governing interfirm relationships.

Abstract

Purpose

This paper assesses whether communication via interpersonal and IT channels accounts for short-term financial performance and long-term orientation and how these effects are influenced by contract completeness and technology usage in platform builder-platform participant relationships.

Design/methodology/approach

The conceptual model and hypotheses are validated through a moderated regression of 384 survey responses from platform participant.

Findings

The empirical results indicate that interpersonal and IT-enabled communication contribute to both short-term financial gains and long-term orientation. The coexistence of interpersonal communication and IT-enabled communication has a synergetic effect on long-term orientation. Contract completeness positively moderates the effect of interpersonal communication on short-term performance while negatively moderating its effect on long-term orientation. Furthermore, contract completeness undermines the effect of IT-enabled communication on short-term performance. Technology usage enhances the effectiveness of interpersonal communication in generating long-term orientation.

Originality/value

First, diverging from the extant research treating communication as a single dimension construct, this study differentiates communication on media channels and shows their separate and synergetic effects on short-term performance and long-term orientation. Second, our empirical findings indicate that the effects of communication are influenced by governance practices, which extends the communication literature. Third, previous studies have presented conflicting results concerning the role of governance mechanisms in inter-firm relationships. By showing that governance mechanisms also either support or suppress communication in generating performance for platform participants, this study extends the existing research on governance mechanisms. Finally, by regarding technology usage as a transactional governance mechanism, this study furthers our understanding of the role of technology in interfirm relationships.

Abstract

Purpose

The purpose of this study is to investigate the heat resistance and heat-resistant oxygen aging of 4-nitrophthalonitrile-etherified cardanol-phenol-formaldehyde (PPCF) to further use and develop the resin as the matrix resin of high-temperature resistant adhesives and coatings.

Design/methodology/approach

PPCF resin was synthesized by 4-nitrophthalonitrile and cardanol-phenol-formaldehyde (PCF). The structures of PPCF and PCF were investigated by Fourier transform infrared, differential scanning calorimetry and proton nuclear magnetic resonance. In addition, the heat resistance and processability of PPCF and PCF resins were studied by dynamic mechanical analysis, thermogravimetric analysis, scanning electronic microscopy (SEM), X-ray diffraction (XRD) techniques and rheological studies.

Findings

The results reveal that PPCF forms a cross-linked network at a lower temperature. PPCF resin has excellent resistance under thermal aging in an air atmosphere and that it still had a certain residual weight after aging at 500°C for 2 h, whereas the PCF resin is completely decomposed.

Originality/value

4-Nitrophthalonitrile was introduced into PCF resin, and XRD and SEM were used to investigate the high temperature residual carbon rate and heat-resistant oxygen aging properties of PPCF and PCF resins.

Abstract

Purpose

Legislation plays a vital role in solving carbon emissions reduction and climate change issues. China began to implement a low-carbon economic policy in 2010, but the effect of the policy needs to be evaluated. Accordingly, this paper aims to discuss China’s low-carbon policy through exploring the following two questions, namely, whether the policy effect reaches the expected goal and whether the policy effects will balance economic development and emission reduction. Then, the paper puts forward suggestions for the improvement of China’s low-carbon policy.

Design/methodology/approach

This paper is organized around three distinct aspects of policy effect evaluation. This paper uses the synthetic control method to construct a policy effect evaluation model and conducts a quasi-natural experiment. The paper selects annual panel data from 2003 to 2015, which is selected from 33 provinces. A comparative analysis of carbon dioxide emissions, energy consumption and economic development between Hubei Province and Liaoning Province.

Findings

The results reveal that the implementation of the low-carbon pilot province policy in 2010 has a significant impact on the emission reduction effect of Liaoning Province, but the impact on the emission reduction effect of Hubei Province is not significant. The carbon emission trading system implemented in 2012 has reduced the emission reductions in Hubei Province and Liaoning Province has achieved better emission reduction effects after the implementation of this policy. After the implementation of the policy, the economic development of Hubei Province has been improved, but it has not brought help to the economic development of Liaoning Province. These findings provide new insights into the use of an emissions trading system for improving economic development and ultimately facilitate the attainment of the broader goal of sustainability.

Originality/value

This paper proposes an innovative policy effect evaluation method by considering the status of unit gross domestic product, fixed asset investment in the energy industry, energy consumption, emission reduction technology innovation and other evaluation indicators. This paper contributes to broadening current methods of policy effect evaluation in China.

Abstract

Purpose

The purpose of this paper is to examine visitors’ motivations for going to the South Luogu Alley, a famous hutong with an over 700-year history in Beijing, China.

Design/methodology/approach

The study applied a self-administered questionnaire to collect data from visitors on the main street of the South Luogu Alley.

Findings

It was found that most visitors of the hutong are casual tourists pursuing relaxation, including tension release and spending time with friends and family; seeking authenticity is not visitors’ most important motivation.

Research limitations/implications

This study used only one hutong to assess visitors’ motivations in hutong tourism, so the results may not be applicable to all hutongs.

Practical implications

The research on the demographics and different motivations of the South Luogu Alley visitors can be useful to managers of tourism-related organizations.

Social implications

This study shows that tourists with different motivations for visiting a hutong have varying requirements for authenticity. The reconstruction of some historical hutongs is not always perceived as negative, and the influence of Western cultural elements can be seen as positive if they contribute to the sustainable development of the local culture.

Originality/value

The term “hutonger,” which includes casual visitors, entertainment seekers, authenticity seekers and pure escapees, based on these respective motivations, is introduced to describe the specific groups of hutong visitors and contribute to the hutong tourism literature.

Abstract

Purpose

This paper aims to study the effect of the establishment of bankruptcy courts on bond issuance market. This paper helps to predict that the introduction of bankruptcy courts in China can mitigate price distortions caused by the implicit government guarantees and promote the development of the high-risk bond market.

Design/methodology/approach

This paper exploits the staggered introduction of bankruptcy courts across cities to implement a differences-in-differences strategy on bond issuance data. Using bonds issued in China between 2018 and 2020, the impact of bankruptcy courts on the bond issuance market can be analyzed.

Findings

This paper reveals that bond issuance credit spreads increase and is more sensitive to firm size, profitability and downside risk of issuance entity after the introduction of bankruptcy courts. It also reveals a substantive increase in bond issuance quantity and a decrease in issuer credit ratings following the establishment of bankruptcy courts. In addition, the increase of credit spreads is more prominent for publicly traded bonds, those whose issuers located in provinces with lower judicial confidence, bonds issued by SOEs and bonds with stronger government guarantees. Finally, the role of bankruptcy courts is more pronounced in regions with higher marketization.

Originality/value

This paper relates to previous studies that investigate the impact of laws and institutions on external financing. It helps provide new evidence to this literature on how improvements of efficiency and quality in bankruptcy enforcements relate to the marketization of bond issuance. The results provide further evidence on legal institutions and bond financing.
