Abstract
Purpose
This study aims to distinguish between service arguments and communication arguments within a home-sharing review and to investigate their roles in consumer purchase decision-making.
Design/methodology/approach
Based on the setting of Airbnb, a 3 (service argument valence: positive, neutral, and negative) × 3 (communication argument valence: positive, neutral, and negative) online experiment was conducted. Data collected from 379 participants were used to test the hypotheses.
Findings
The three main determinants of purchase intention: perceived host service quality, perceived facility service quality, and perceived social value, are affected by both service arguments and communication arguments. Service arguments positively influence perceived host service quality and perceived facility service quality, while communication arguments contribute significantly to perceived host service quality and perceived social value. However, perceived facility service quality is affected by the combination of service arguments and communication arguments rather than by the service arguments only, because service argument trustworthiness, a factor influencing the effect of service arguments, varies across the combination of two types of arguments.
Practical implications
This research helps home-sharing platform managers to understand how to facilitate transaction success through displaying different review arguments needed by consumers. Additionally, the dual role of communication arguments emphasizes a necessity for hosts to encourage positive communication arguments and provide additional cues on the facility service quality.
Originality/value
The service arguments and communication arguments in home-sharing reviews are distinguished, and their distinct roles in consumers' purchase intention have been uncovered.

Abstract
Mindfulness-based interventions are on the rise in workplace settings to enhance Well-Being and address work stress. Their popularity is in part due to the fact that they are often assumed to have a net positive impact on both workers’ Well-Being and organizational functioning. However, the majority of workplace mindfulness practice and research focuses on individual-level mindfulness interventions and their associated outcomes, like reduced stress. However, the modern workplace is highly dependent on positive team functioning, and the impact of mindfulness in teams is lesser known. This review differentiates individual mindfulness from team mindfulness and explores how both individual and team mindfulness impact team functioning. The authors review mindfulness and teams’ literature to understand antecedents, correlated mediators, and consequences of mindfulness in team contexts, team processes, and the boundary conditions related to mindfulness outcomes. This review adds to the budding theoretical conversation regarding mindfulness at work and contributes valuable insight into the practical applications of mindfulness in teams.

Abstract
Purpose
The intelligent Central Traffic Control (CTC) system plays a vital role in establishing an intelligent high-speed railway (HSR) system. As the core of HSR transportation command, the intelligent CTC system is a new HSR dispatching command system that integrates the widely used CTC in China with the practical service requirements of intelligent dispatching. This paper aims to propose key technologies and applications for intelligent dispatching command in HSR in China.
Design/methodology/approach
This paper first briefly introduces the functions and configuration of the intelligent CTC system. Some new servers, terminals and interfaces are introduced, which are plan adjustment server/terminal, interface for automatic train operation (ATO), interface for Dynamic Monitoring System of Train Control Equipment (DMS), interface for Power Supervisory Control and Data Acquisition (PSCADA), interface for Disaster Monitoring, etc.
Findings
The key technologies applied in the intelligent CTC system include automatic adjustment of train operation plans, safety control of train routes and commands, traffic information data platform, integrated simulation of traffic dispatching and ATO function. These technologies have been applied in the Beijing-Zhangjiakou HSR, which commenced operations at the end of 2019. Implementing these key intelligent functions has improved the train dispatching command capacity, ensured the safe operation of intelligent HSR, reduced the labor intensity of dispatching operators and enhanced the intelligence level of China's dispatching system.
Originality/value
This paper provides further challenges and research directions for the intelligent dispatching command of HSR. To achieve the objectives, new measures need to be conducted, including the development of advanced technologies for intelligent dispatching command, coping with new requirements with the development of China's railway signaling system, the integration of traffic dispatching and train control and the application of AI and data-driven modeling and methods.

Abstract
Purpose
The purpose of this paper is to develop a kind of novel and high‐performance rheological additive, an eco‐friendly composite of anatase nano‐TiO2 particles and xanthan gum (NTX), for interior wall coatings.
Design/methodology/approach
NTX was prepared through heating and refluxing the mixture of TiO2 hydrosol and xanthan gum, and five interior wall coating samples were fabricated with different NTX contents. The morphology of nano‐TiO2 hydrosol and NTX were characterised with TEM, and the stability and rheological properties of these coating samples were studied.
Findings
TEM images showed a core‐shell structure of NTX, and that nano‐TiO2 particles in it were encapsulated by xanthan gum, which was anticipated to weaken Van der Waals force among nano‐TiO2 particles thus preventing the aggregation of nano‐particles. All of the five coating samples were found to be non‐Newtonian pseudo‐plastic fluid, and showed excellent stability and thixotropic property.
Research limitations/implications
This paper focused on the preparation, the characterisation of NTX additive and the study of the rheological behaviours of the coating samples with NTX. Some other aspects, such as coating durability, photocatalytic ability and film properties, will be studied in the future.
Practical implications
It was proven that NTX was an effective eco‐friendly rheological additive for interior wall coatings. Consequently, this paper threw light on developing eco‐friendly interior wall coatings.
Originality/value
A kind of novel and effective rheological additive was developed for interior wall coatings in the study reported in the paper. A method was also developed to introduce functional nano‐particles into coating in a good dispersion state.

Abstract
Purpose
The purpose of this paper is to study some evolving mechanisms for producing weighted networks, as well as to analyze the statistical properties of the networks.
Design/methodology/approach
A simple one‐parameter evolution model of weighted networks is proposed, in which the topological growth combines with the variation of weights. Based on weight‐driven dynamics, the model can generate scale‐free distributions of the degree, node strength and edge weight, as confirmed in many real networks.
Findings
The exponent of the edge weight can be widely tuned. The unique parameter p controls the edge weight dynamical growth. The authors also obtain the non‐trivial weighted clustering coefficient and the weighted average to the nearest neighbors' degree.
Research limitations/implications
Accessibility and availability of data are the main limitations which apply to the figures.
Practical implications
The new evolving networks method may be beneficial for understanding real networks.
Originality/value
The paper proposes a new approach of explaining the evolving mechanisms of the real networks.

Abstract
Purpose
This paper aims to investigate the electrolytic deposition of corrosion-resistant chromium coatings from a trivalent chromium plating bath based on deep eutectic solvent, a new generation of room temperature ionic liquids.
Design/methodology/approach
The electrolyte contained chromium (III) chloride, choline chloride and the additive of extra water. The surface morphology was estimated by means of SEM technique. The microstructure of as-deposited and annealed coatings was studied using X-ray diffraction method. The kinetics of the chromium electrodeposition and the corrosion electrochemical behavior of the coatings were investigated by cyclic voltammetry technique.
Findings
Chromium coatings with an amorphous type of microstructure are electroplated from this bath. Some carbon and oxygen are included in deposits obtained. The step-wise mechanism of the electrochemical reduction of Cr(III) ions to Cr(0) is detected. The current efficiency in this system sufficiently exceeds that typical of usual aqueous electrolytes. The coatings fabricated using plating bath based on deep eutectic solvent showed enhanced corrosion resistance in an acidic medium: there is no current peak of active dissolution in polarization curve and the corrosion potential shifts to more positive values as compared with “usual” chromium.
Originality/value
The electrodeposition of chromium coatings from an environmentally acceptable trivalent chromium electrolyte, a deep eutectic solvent containing chloride choline and extra water additive has been investigated for the first time.

Abstract
Purpose
Building on theories of inter-organizational knowledge flows and social network, we explored how two types of collaboration network embeddedness (NE) (i.e. structural embeddedness (SE) and relational embeddedness (RE)) drive firms' inbound and outbound open innovation (OI) practices from a knowledge flow perspective, and further examined these relationships are to what extent contingent on network inertia (NI).
Design/methodology/approach
In this empirical research, the authors collected a sample of patents in the unmanned aerial vehicle (UAV) industry over the period of 2000–2018. Then the authors examined the direct roles of SE and RE in collaboration networks on firms' inbound and outbound OI practices from a knowledge flow perspective, and the moderating role of NI by using negative binomial regression.
Findings
Empirical results from our study of 96 firms showed that both bridging structural holes position in collaboration networks (i.e. SE) and having stronger tie strength (i.e. RE) would positively affects firms' inbound OI practices, whereas only having stronger tie strength in collaboration networks (i.e. RE) would facilitate outbound OI practices. In addition, NI strengthens the relationships between SE and firm OI practice, but weakens the positive roles of RE on firm OI practice.
Originality/value
This empirical research provides new insights into whether and how firms can grasp the benefits of collaboration NE to conduct OI activities by exploring NI contingencies. It further sheds lights on the scope of the NE–OI issue from a knowledge flow perspective by extending its research context to UAV industry.

Abstract
Purpose
The purpose of this paper is to elucidate the tribology behavior of polytetrafluoroethylene (PTFE) incorporated with three types of nickel–phosphorus (Ni-P) particles (i.e. low phosphorus [LP], medium phosphorus [MP] and high phosphorus [HP]) under dry sliding condition.
Design/methodology/approach
Ni-HP, Ni-MP and Ni-LP particles fabricated via an electroless plating process were incorporated into PTFE matrix with different additions to prepare Ni-P/PTFE composites (Ni-LP/PTFE, Ni-MP/PTFE and Ni-HP/PTFE). The tribology tests for these samples were carried out on a reciprocating ball-on-disc tribometer. The thermal stabilities, mechanical and tribological properties, morphologies and components of aforesaid Ni-P/PTFE composites were analyzed.
Findings
The marvelous effect of Ni-P incorporation on the simultaneous reduction in friction and wear of PTFE was corroborated.
Originality/value
Compared with that of pristine PTFE sample, the reduction on friction with a value of 27% and the reduction in wear about 94% for Ni-HP/PTFE composite is validated, which is probably related to the increased crystallinity and hardness due to the presence of Ni-P particles.

Abstract
Purpose
This paper aims to investigate the improvement of Sn58Bi solder properties by Ni nanoparticle to provide theoretical support in the field of electronic packaging.
Design/methodology/approach
In this study, nickel nanoparticles (Ni NPs) were doped into Sn58Bi solder as a reinforcing agent to prepare a composite solder. The wettability of composite solder, melting characteristics of solder alloy, microstructure of joints, mechanical properties and intermetallics growth at the interface were investigated.
Findings
Test results show that Ni had little substantial effect on the solders alloy melting temperature yet decreased the alloy undercooling. Notably, Ni enhanced solders wettability on Cu substrates. The spreading area increased by 14% at 0.6 wt.% Ni. The Ni refined the microstructure of Sn58Bi solder joints and inhibited the coarsening of the Bi-rich phase in the solder. At the same time, it also led to the production of free intermetallic compounds, increasing growth of the intermetallic compound (IMC) layer. However, upon surpassing 0.6 wt.% Ni, (Cu, Ni)6Sn5 accumulated and formed irregular clumps in the matrix. The grain size of the IMC layer gradually decreased as Ni was added. In shear tests, the fracture of joints occurred mainly inside the solder matrix. Sn58Bi-0.6Ni joints displayed a 40% rise in shear strength and a 25% rise in Vickers hardness. In addition, the appearance of dimples at the fracture indicated the improved flexibility of joints.
Originality/value
In this paper, Ni nanoparticle with different contents were added to Sn58Bi solder to prepare a composite solder, and the properties of the composite solder were investigated from different perspectives.
