Literature proposes that implementing supplier assessment and supplier collaboration simultaneously may lead to better sustainable performance. The purpose of this paper is to empirically examine the proposition by considering the contingent effects of two contextual factors, the environmental dynamism and the stakeholder pressure on sustainability.

Four configurations of governance mechanisms are identified according to the different levels of implementing supplier assessment and supplier collaboration. The performances of the four configurations are compared against the levels of environmental dynamism and stakeholder pressure. The empirical data from the sixth round of International Manufacturing Strategy Survey (IMSS) are used.

This paper found that the governance configuration with the highest level of implementing both governance mechanisms leads to the best performance. The synergistic effect that supplier assessment and collaboration complement each other to achieve better performance is verified. However, the synergistic effect holds robust only when the environmental dynamism and stakeholder pressure are high. The synergistic effect vanishes in the social and environmental performance when the environmental dynamism is low. The effect also vanishes in the environmental performance when the stakeholder pressure is low. No synergistic effect was found in business performance.

This paper reveals the complementarity between supplier assessment and supplier collaboration when they are implemented at a reasonably high level. It also reveals the importance of the fit of governance mechanisms under different external contexts. The results contribute to reconciling the disputes about the effectiveness of governing supplier relationship to achieve the sustainability along a supply chain.

The importance of supplier integration (SI) in improving firms’ performance has been previously identified but the effects of SI are complicated, as the relationship between supplier and buyer is full of uncertainty. The purpose of this paper is to re-examine the effects of SI on operations performance from a relational view.

Two strategies of integrating suppliers are theoretically presented: information sharing and joint decision making. Hypotheses are then developed on when SI influences operations performance, using product complexity and competitive intensity as moderating factors. The hypotheses are tested using a global survey data set, made up of 763 manufacturing firms from 22 countries.

The results indicate a positive relationship between SI and operations performance and that the moderating roles of product complexity and competition intensity are significant, but product complexity does not have significant moderation effects on the relationships between joint decision making and product quality/cost reduction.

The moderators of product complexity and competitive intensity are not comprehensive. Future study into how and under what circumstances SI has the greatest effect will be of benefit.

This study makes theoretical contributions by exploring the strategies of SI through a relational view, and examining the effects of SI through the moderating roles of product complexity and competition intensity.

This study aims to examine the trustworthiness of internet-based quality signals (specifically webpages and before-sale services) from the perspective of interactivity by evaluating the associations between on-line signals of product quality and the off-line perceived quality of actual products.

Empirical data are collected from 261 Chinese female university students. Partial least squares structural equation modelling is used to test the conceptual model.

Both webpages and before-sale services are positively associated with off-line perceived quality, but only the quality of before-sale service has a direct association with customer satisfaction. Webpages and before-sale services are both trustworthy signals for indicating the quality of physical products; however, these signals provide different levels of trustworthiness.

The interactivity perspective supplements information-economics theory in examining the trustworthiness of internet-based signals. A signal is a trustworthy indicator only if customers perceive a close relationship between the quality of the signal and the actual product quality.

On-line sellers should improve the reciprocity and controllability of communications from a buyer’s perspective and should pay more attention to the strategic role of on-line communication for improving customer service.

Researchers have evaluated the trustworthiness of on-line quality signals from an information-economics perspective. This study extends these previous studies by addressing the perspective of interactivity. Two types of product-quality signals, including webpages and before-sale services, are assessed in terms of their trustworthiness by examining how these signals relate to off-line perceived quality and customer satisfaction.

There are many studies on the impact of supply chain integration (SCI) on performance. However, the definitions, the measurements, the sample sizes, and scope of both SCI and the performance vary significantly from research to research. Conclusions are not consistent either. Researchers still believe that little is known about the impact of SCI on performance and call for more empirical research. The purpose of this paper is to investigate the impact on quality practices and quality performance of upstream integration with suppliers and downstream integration with customers.

The research is based on the empirical data from a large international survey of over 600 manufacturing companies from 20 countries. An intensive literature review was conducted on the definition and scope of SCI as well as its relationship with quality practice and performances. In total, five hypotheses were formulated and a conceptual model was proposed. Structural equation modeling (SEM) was used to test the hypotheses reflecting and interrelationship among the four variables.

The research reveals that downstream integration with customers influences both the quality management practice and the quality performance of the company, while upstream integration with suppliers only influences the quality practice but not the quality performance.

This research is different to previous research in three aspects. First, SCI covers both the upstream integration with suppliers and downstream integration with customers. Second, integration measurement covers both material integration and information integration. Third, it considers both quality management practices and quality performance.

The purpose of this paper is to investigate the retailer’s strategy of information sharing in a green supply chain with promotional effort, and the impact of information sharing on the decisions and profits of the manufacturer and the retailer.

The developed models aim to maximize the profits of the manufacturer, the retailer and the green supply chain system. The game theory is used to obtain the equilibrium solutions of both the manufacturer and the retailer. A two-part compensation (TPC) contract is designed to motivate the retailer to share information with the retailer. Numerical examples are used to show the impact of parameters on decisions by Matlab 2014.

The results show that the green degree increases while the promotional effort level decreases when the manufacturer receives the larger demand information from the retailer; information sharing leads to a profit increase to the manufacturer and a profit loss to the retailer, but can increase the profit of supply chain under a certain condition; information sharing reduces the expected consumer surplus. The TPC contract designed in this paper can not only motivate the retailer to share information but also increases the consumer surplus.

The study has been done in a monopoly environment where only a retailer can forecast demand information. It is an interesting direction of future research when considering there are more retailers who can forecast such information in a supply chain.

There exist two main aspects that are different from the existing literature. The stochastic demand function related to the retail price, the green degree and the promotional effort have never appeared in previous literature. This paper considers a green product supply chain with a manufacturer who produces green products and a retailer who has an information advantage because of her promotional effort; this paper investigates the impact of information sharing on the consumer surplus and designs a contract to coordinate the green supply chain.

The paper seeks to investigate the laser engineered net shaping (LENS) of metal thick‐wall parts from Ni‐based alloy powders.

The composition of Ni‐based alloy powders was determined from phase diagram, which was 84Ni14.4Cu1.6Sn. The powders were prepared by gas atomization. Deoxygenation and screen separation were applied to the powders to improve the sintering ability and narrow the particle size distribution before shaping. Thick‐wall metal parts were built by LENS under different conditions. The microstructures, surface morphologies of the prepared parts were characterized.

The gas atomized powders were almost uniformly spherical after sieving. Most of oxygen contained in the alloy powders could be removed in H₂ atmosphere for heating at 550°C for 2 h. These nickel‐based alloy powders with 150‐200 mesh size were suitable for powder feed system. And these powders were shaped successfully by LENS. Thick‐wall parts with thickness ranged from 20 to 25 mm were fabricated. The thickness of each layer was between 400 and 600 μm by scanning electron microscope. Metallographs revealed that dendritic structures with different characteristics were grown on XY‐, YZ‐ and XZ‐section.

The present experiments were limited by the atmosphere control during the LENS process. The oxide at the interface between two neighbor layers could decrease the mechanical properties if without good inert gas protection, such as a protective atmosphere chamber.

This paper describes a refined experimental program that is needed to resolve the remaining technical issues in LENS of thick‐wall parts. The nickel‐based alloy powders suitable for the LENS process were studied and prepared. After pretreatment, the self‐made powders have good shaping ability. Microstructure features were first discussed with the variation of the face orientation. The dendrite arm distance obtained by this experiment is between 8 and 20 μm, well conforming to the theory. The thick‐wall parts with dense structures were fabricated successfully to widen the field of application of LENS.

This study aims to explain the market-oriented transformation dilemma of Chinese urban investment and development companies (UIDCs; also known as local government investment and financing companies) and objectively evaluate their transformation efficiency from both static and dynamic perspectives. The results of the research provide methodological bases for improving the transformation efficiency of UIDCs, thus pointing out the direction for the rational planning of their transformation path.

This study takes Chinese UIDCs in market transformation during 2015–2019 as the research object and uses principal component analysis to screen the index system for measuring the efficiency of market transformation. It then uses a three-stage data envelopment analysis model and the Malmquist productivity index to evaluate the market transformation efficiency of these companies during 2015–2019 and comprehensively analyzes the influence of external environmental factors on the market transformation of Chinese UIDCs.

Research results show that the transformation efficiency of Chinese UIDCs is low and slow overall and that large spatial and temporal differences exist. The transformation efficiency of UIDCs located in eastern China is higher than that of UIDCs in central and western China. The higher the external environmental factors of regional GDP, local debt service pressure and credit rating, the more likely they are to cause input redundancy in the transformation process of Chinese UIDCs, which is not conducive to their market-oriented transformation. In addition, the higher the urbanization rate, the more effective it is to improve the efficiency of market-oriented transformation of UIDCs. If the influence of environmental factors is stripped away, both the overall efficiency value and pure technical efficiency value of market-oriented transformation of Chinese UIDCs will increase while the scale efficiency value becomes smaller.

This research measures the transformation efficiency of Chinese UIDCs and comprehensively analyzes the influence of external environmental factors on their market-oriented transformation. The goal is to enrich the study of the market-oriented transformation efficiency evaluation index system of Chinese UIDCs at the theoretical level and provide important reference values for improving the efficiency of market-oriented transformation of Chinese UIDCs at the practical level.

This paper aims to investigate the stress corrosion cracking (SCC) process of sensitized 304 stainless steel during the slow strain rate test by using the electrochemical noise (EN) technique.

EN data are interpreted based on chaos and wavelet analyses, and correlation dimension and wavelet energy distribution are used as indicators for SCC process identification.

Experimental results reveal that the corrosion potential abruptly decreases from 180 to 100 mV at 6,300 s and the current increases from 10 to 100 nA accordingly, which is attributed to passive film breakdown and crack initiation. Chaos and wavelet analyses results reveal that, as crack initiates, the correlation dimensions increase from 1.2 to 1.9, and the corresponding distribution frequencies of maximum relative wavelet energy change from high frequency to low frequency.

SCC is monitored in lab, and crack initiation and propagation are identified by chaos and wavelet analyses. This work lays the foundation for SCC detection in field using EN.

This paper aims to investigate the tribological properties of polytetrafluoroethylene (PTFE) composites modified by nano-serpentine and nano-lanthanum oxide in a seawater environment.

In this paper, seven PTFE composites were prepared by unified design method and vacuum thermoforming method, and their hardness, water absorption and tribological properties were measured under seawater environment. The modification effects and thermal stability of the materials were analyzed by Fourier transform infrared spectroscopy, thermal gravimetry and differential scanning calorimetry. This paper analyzed the wear mechanism of PTFE composites by scanning electron microscopy and energy spectroscopy.

The results showed that the hardness of the PTFE composites were all improved, but the water absorption was increased with the increase of additives. The modification of nano-serpentine was successful and the thermal stability of PTFE composites was better. The lowest coefficient and minimum wear rate are 0.0267 and 8.67 × 10⁻⁵ · mm³ · (N · m)⁻¹ respectively, which is 34.9% and 76% less than the pure PTFE.

The analysis showed that the wear mechanism of PTFE composites was abrasive wear and a small amount of adhesive wear, and when the additive content was appropriate, it easily formed a transfer film on the surface mating parts.

The purpose of this study is to reveal the effect of nano-Al₂O₃ particle addition on the nucleation/growth kinetics, microhardness, wear resistance and corrosion resistance of Co–P–xAl₂O₃ nanocomposite plating.

The kinetics and properties of Co–P–xAl₂O₃ nanocomposite plating prepared by electroplating were investigated by electrochemical measurements, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Vickers microhardness measurement, SRV5 friction and wear tester and atomic force microscopy.

A 12 g/L nano-Al₂O₃ addition in the plating solution can transform the nucleation/growth kinetics of the plating from the 3D progressive model to the 3D instantaneous model. The microhardness of the plating increased with the increase of nano-Al₂O₃ content in plating. The wear resistance of the plating did not adhere strictly to Archard’s law. An even and denser corrosion product film was generated due to the finer grains, with a high corrosion resistance.

The effect of different nano-Al₂O₃ addition on the nucleation/growth kinetics and properties of Co–P–xAl₂O₃ nanocomposite plating was investigated, and an anticorrosion mechanism of Co–P–xAl₂O₃ nanocomposite plating was proposed.
