Abstract

Purpose

The image of the construction industry in China, as in many other countries, is tarnished by its poor safety record. With the rapid development of subway systems in Chinese urban areas, construction workers are being exposed to new risks which are poorly understood and managed. Subway construction projects are large scale and scattered over many construction sites, and involve numerous stakeholders and sophisticated technologies in challenging underground environments. Accident rates are high and have significant economic and social consequences for the firms and people involved. Addressing the gap in research about the safety risk in these projects, the purpose of this paper is to advance understanding of the factors influencing the safety of Chinese subway construction projects with the overall objective of reducing accident rates.

Design/methodology/approach

A survey was conducted with 399 subway construction professionals across five stakeholder groups. Follow-up interviews were also conducted with five experienced experts in safety management on subway projects to validate the results.

Findings

It was found that the eight most critical factors perceived by stakeholders to influence safety risks on Chinese subway projects are: project management team; contractor-related factors; site underground environment; safety protection during the use of machines; safety management investment; site construction monitoring and measurement; hazard identification and communication; and use of machines in all stages. This indicates that in allocating limited project resources to improve the safety of subway projects, managers should focus on: developing safety knowledge and positive attitudes in leadership teams; formulating effective risk management systems to identify, assess, mitigate, measure and monitor safety risks on site; improving communications with stakeholders about these risks and effectively managing plant, equipment and machinery.

Originality/value

This research contributes a new multi-stakeholder perspective to the lack of safety research in Chinese subway construction projects. The research findings provide important new insights for policymakers and managers in improving safety outcomes on these major projects, producing potentially significant social and economic benefits for society and the construction industry.

Abstract

Purpose

This study aims to answer few questions, such as which factors influence the local government’s choice of private firm investments; what factors influence private firms’ choice of specific local government to make a local investment; and why do some private firms gain a competitive edge by choosing a stakeholder management model of “running the government” in the context of the Chinese transition economy.

Design/methodology/approach

Using a case study approach, this paper provides an in-depth analysis of the Daqing–Geely Case, 2010, and explains why Geely chose Daqing considering the firm perspective and why the Daqing city Government chose Geely considering the local governments’ perspective.

Findings

This study highlights the concept of “co-beneficial” cooperation between government–business by virtue of the institutional innovation of the quasi-property system. In addition, it reveals that the private firms and local governments in the “Daqing–Geely mode” work together for mutual benefits by putting fair negotiation and contract mechanisms in place. Resultantly, private firms secure the commercial interests, and the local governments bring in improved efficiency.

Originality/value

This study consolidates the theory of stakeholders, thereby strengthening the current understanding of “special offer” and “universal offer.”

Abstract

Purpose

This study aims to focus on the effect of interlayer bonding and thermal decomposition on the mechanical properties of fused filament fabrication-printed polylactic acid specimens at high extrusion temperatures.

Design/methodology/approach

A printing process, that is simultaneous manufacturing of contour and specimen, is used to improve the printing accuracy at high extrusion temperatures. The effects of the extrusion temperature on the mechanical properties of the interlayer and intra-layer are evaluated via tensile experiments. In addition, the microstructure evolution affected by the extrusion temperature is observed using scanning electron microscopy.

Findings

The results show that the extrusion temperature can effectively improve the interlayer bonding property; however, the mechanical properties of the specimen for extrusion temperatures higher than 270°C may worsen owing to the thermal decomposition of the polylactic acid (PLA) material. The optimum extrusion temperature of PLA material in the three-dimensional (3D) printing process is recommended to be 250–270°C.

Originality/value

A temperature-compensated constitutive model for 3D printed PLA material under different extrusion temperatures is proposed. The present work facilitates the prediction of the mechanical properties of specimens at an extrusion temperature for different printing temperatures and different layers.

Abstract

Purpose

Online retailers are pioneering the incentivization of customers to generate more product reviews by rewarding them. However, little is known about the impact of reward types on customers' review behavior, including review frequency and sentiment. To address this gap, we investigated the effects of different reward types on customers' review behavior and how these rewards influence customers' review behavior.

Design/methodology/approach

We collected secondary data and empirically tested the hypothesis by analyzing the change in reward policy. Regression and two-stage Heckman models were applied to investigate the effects, with the latter used to control potential selection issues.

Findings

The results revealed that monetary rewards can stimulate customers to generate more positive product reviews. Furthermore, the reward amount has a negative moderating effect on the aforementioned relationship. Additionally, customer tenure negatively moderates the relationship between monetary rewards and review behavior.

Originality/value

This study contributes to the understanding of user-generated content motivation and provides managerial implications for reward programs.

This study aims to investigate the effect of post-treatment on anti-corrosion performance of Al coating on the surface of Ti-6Al-4V (TC4) fastener.

Abstract

Purpose

This study aims to investigate the effect of post-treatment on anti-corrosion performance of Al coating on the surface of Ti-6Al-4V (TC4) fastener.

Design/methodology/approach

The Al coatings with different layer structures were prepared on TC4 by middle-frequency and direct-current combined magnetron sputtering. The cross-sectional morphology and surface roughness of coatings were characterized by scanning electron microscope and atomic force microscope. The corrosion resistance was evaluated by electrochemical method. The monolayer coating was post-treated by Alodine chemical conversion, Ar+ bombardment and a combination of two methods above.

Findings

The results show that the interfaces in bilayer and trilayer coatings reduce the defects. Ar+ bombardment reduces the corrosion current density, and Alodine chemical conversion leads to a higher pitting corrosion potential. The combined post-treatment has the highest polarization resistance.

Originality/value

The corrosion resistance of the Al coating is enhanced as the layer quantity increases. The combination of two post-treatments, Ar+ bombardment and Alodine chemical conversion, could achieve an overall improvement in corrosion resistance of Al coating.

Abstract

Purpose

The substantial cost of employee cyberloafing to organizations calls for research into exploring the factors that influence such behavior. Drawing upon social cognitive theory, the authors develop a theoretical model that unpacks when and why leader forgiveness induces employee cyberloafing. Specifically, the authors identify moral disengagement as a linking mechanism and employee empathic concern as a key boundary condition in the association between leader forgiveness and employee cyberloafing behaviors.

Design/methodology/approach

The authors conducted multilevel analyses to examine the authors' hypotheses by utilizing a sample of 71 supervisors and 306 direct reports.

Findings

Results showed that leader forgiveness encouraged employee cyberloafing via moral disengagement among employees with low empathic concern, whereas the indirect effect was not present among those with high empathic concern.

Originality/value

The authors contribute to the literature on cyberloafing and leader forgiveness. First, this study extends the cyberloafing research by considering leader forgiveness as an enabler, challenging the dominant notion that positive leader behaviors (e.g. leader mindfulness) constrain employee cyberloafing while negative leader behaviors (e.g. abusive supervision) elicit it. Second, although past studies have predominantly concentrated on the positive outcomes of forgiveness, the current research contributes to the balanced and comprehensive understanding of leader forgiveness by linking leader forgiveness with employee cyberloafing.
