Abstract
Purpose
The prolonged training time of the neural network (NN) has sparked considerable debate regarding their application in the field of optimization. The purpose of this paper is to explore the beneficial assistance of NN-based alternative models in inductance design, with a particular focus on multi-objective optimization and uncertainty analysis processes.
Design/methodology/approach
Under Gaussian-distributed manufacturing errors, this study predicts error intervals for Pareto points and select robust solutions with minimal error margins. Furthermore, this study establishes correlations between manufacturing errors and inductance value discrepancies, offering a practical means of determining permissible manufacturing errors tailored to varying accuracy requirements.
Findings
The NN-assisted methods are demonstrated to offer a substantial time advantage in multi-objective optimization compared to conventional approaches, particularly in scenarios where the trained NN is repeatedly used. Also, NN models allow for extensive data-driven uncertainty quantification, which is challenging for traditional methods.
Originality/value
Three objectives including saturation current are considered in the multi-optimization, and the time advantages of the NN are thoroughly discussed by comparing scenarios involving single optimization, multiple optimizations, bi-objective optimization and tri-objective optimization. This study proposes direct error interval prediction on the Pareto front, using extensive data to predict the response of the Pareto front to random errors following a Gaussian distribution. This approach circumvents the compromises inherent in constrained robust optimization for inductance design and allows for a direct assessment of robustness that can be applied to account for manufacturing errors with complex distributions.

Abstract
Purpose
The purpose of this paper is to examine the influences of positive-framed and negative-framed green advertising on pro-environmental WTP. This study also explores the impacts of regulatory focus, environmental concern and pleasant level on green advertising effectiveness.
Design/methodology/approach
Data are collected from a within-participant between-group online experiment in China. The generalized estimating equation (GEE) is employed to investigate the impact of green advertising on WTP. Grouped regression and mediation analyses are conducted to explore the influences of regulatory focus, environmental concern and pleasure on advertising efficacy.
Findings
The experimental outcomes indicate that green advertising significantly increases participants’ pro-environmental WTP, and negative-framed advertising is more effective than its positive-framed counterpart. Prevention focus heightens receptivity to green advertising, and the relation of environmental concern to advertising effectiveness is inverted U-shaped. Pleasure mediates the effect of green advertising on the WTP, and this mediating role is influenced by emotional intensity when advertising is negatively framed.
Originality/value
Evidence suggests that green advertising may propel pro-environmental WTP by raising environmental awareness, but such a relationship remains severely understudied. As such, this study pioneers in exploring the impact of different-framed green advertising on pro-environmental WTP, extending the concept of green advertising to environmental management. By considering the influences of regulatory focus, environmental concern and pleasure, this study raises practical implications for designing green advertisements, such as increasing the usage of visual elements.

Abstract
Purpose
The purpose of this study is to explore the role of social media usage among business-to-business sales professionals in China. Specifically, the authors seek to define and explore the unique ways in which Chinese salespeople use social media, with a special emphasis on the role of guanxi. Guanxi is a complex cultural construct that revolves around the exchange of favors to build trust and connection for business purposes.
Design/methodology/approach
Three in-depth interviews of sales managers from two industries along with survey data from 42 pharmaceutical sales representatives were collected to gain an understanding of the general usage and attitudes toward social media in the sales process in China.
Findings
Results indicated that virtually all the salespeople in the sample were highly familiar with social media and integrated it into the sales process. Furthermore, all participants indicated that their companies were highly supportive of the use of social media with their customers. More importantly, salespeople in China view social media as a critical tool in building guanxi with their customers. Findings from this exploratory study are used to create a conceptual framework for understanding the important role of social media in building guanxi in China.
Research limitations/implications
While the sample is limited to three managerial interviews and 42 survey responses, the data indicated a near universal acceptance and use of social media among Chinese salespeople. Most importantly, social media appears to be the modern gateway to the ancient and culturally unique construct of guanxi that is absolutely indispensable to successful business-to-business sales performance in China.
Practical implications
The structural challenges within China make trust and emotional connection essential to any potential business relationship. Trust is at the core of guanxi. Any firm hoping to succeed in China must understand guanxi and the use of Chinese social media to help build it. This study adds to the knowledge and understanding of guanxi and begins to elucidate the uses of social media as a tool to build and maintain it.
Social implications
Social media appears to be the modern gateway to the ancient and culturally unique construct of guanxi that is absolutely indispensable to successful business-to-business sales performance in China. This study deepens our understanding of not only guanxi but also how the modern phenomenon of social media is affecting it.
Originality/value
This is one of very few studies to investigate the use of social media among salesforces in China. More importantly, the authors know of no other study linking social media with guanxi.

Abstract
Purpose
Stainless-clad bimetallic steels (SCBS) are widely investigated in some extremely environmental applications areas, such as polar sailing area and tropical oil and gas platforms areas, because of their excellent anticorrosion performance and relatively lower production costs. However, the properties of SCBS, including the mechanical strength, weldability and the anticorrosion behavior, have a direct relation with the manufacturing process and can affect their practical applications. This paper aims to review the application and the properties requirements of SCBS in marine environments to promote the application of this new material in more fields.
Design/methodology/approach
In this paper, the manufacturing process, welding and corrosion-resistant properties of SCBS were introduced systematically by reviewing the related literatures, and some results of the authors’ research group were also introduced briefly.
Findings
Different preparation methods, such as rolling composite, casting rolling composite, explosive composite, laser cladding and plasma arc cladding, as well as the process parameters, including the vacuum degree, rolling temperature, rolling reduction ratio, volume ratios of liquid to solid, explosive ratio and the heat treatment, influenced a lot on the properties of the SCBS through changing the interface microstructures. Otherwise, the variations in rolling temperature, pass, reduction and the grain size of clad steel also brought the dissimilarities of the mechanical properties, microhardness, bonding strength and toughness. Another two new processes, clad teeming method and interlayer explosive welding, deserve more attention because of their excellent microstructure control ability. The superior corrosion resistance of SCBS can alleviate the corrosion problem in the marine environment and prolong the service life of the equipment, but the phenomenon of galvanic corrosion should be noted as much as possible. The high dilution rate, welding process specifications and heat treatment can weaken the intergranular corrosion resistance in the weld area.
Originality/value
This paper summarizes the application of SCBS in marine environments and provides an overview and reference for the research of stainless-clad bimetallic steel.

Abstract
Purpose
Although the existing literature indicates the strategy of decentralization adopted by the Chinese government has permitted the introduction of transnational higher education (TNHE) into mainland China at its very beginning in the 1980s, relatively little research has been conducted to explore the effects of the ensuing-released policies on the development of TNHE after then, especially at institutional level. The purpose of this paper is to fill this research gap by presenting data/information about recent development of TNHE in China and analyzing teachers’/students’ perceptions of autonomy enjoyed by the newly emerging cooperation type, Sino-foreign cooperation universities.
Design/methodology/approach
Based upon the purposive sampling method, we chose University A and B as case studies in this research to ensure the representativeness, since they cooperate separately with the major exporters of TNHE in China. In addition, key informants and snowball sampling were adopted to select our respondents. In total 5 administrative staff and 12 students were interviewed to evaluate their working/ learning experience there. The detailed information about the interviewees are listed as Appendix.
Findings
The fieldwork conducted in 2014 and 2015 reveals the governance model toward Sino-foreign cooperation universities could be categorized as predominantly decentralized. Specifically, the authors listed the most obvious aspects showing the different level of autonomy enjoyed by different cooperation types below: the internal administrative structure, the enrollment capacity, the criteria of admission and the quality assurance method.
Originality/value
This paper critically explores how local education bureaus regulate these TNHE programs in general and monitor the operation of the overseas university campuses being founded in China in particular. In addition, this paper also reports the field interviews with faculty members and students, particularly their evaluation of working/learning experiences in the field of TNHE. Most important of all, this paper critically reflects upon the changing educational governance and explores what regulatory regime could better conceptualize the changing state-TNHE relations in China.

Abstract
Purpose
This study aimed to identify barriers impeding circular economy (CE) uptake in the construction industry in literature, categorize them for the development of a framework and to seek the interrelationships among the categorized barriers. This allowed for identifying integrated solutions to holistically address the barriers. The study also sought to identify the “hot” themes, the knowledge gaps and future research directions on barriers impeding CE.
Design/methodology/approach
Forty-eight relevant articles were desk reviewed from different construction peer-reviewed journals and published conference papers. A scientometric analysis allowed for co-occurrence of keywords relating to CE. A content analysis enabled the identification of 79 barriers impeding the uptake of CE in the construction industry which were further categorized into six distinct categories for the development of a framework showing the interrelationships among the categorized barriers.
Findings
The identified barriers include construction sector inertia, lack of design standards, lack of knowledge, awareness and understanding, design cost, and perception of second-hand materials as substandard among others. The study categorized the identified barriers for better understanding into six different groups: cultural barriers, social barriers, environmental barriers, economic barriers, technical barriers and technological barriers. Strategies to address the barriers were also proposed. The interrelationships among the various barriers were also shown in a proposed framework to educate professionals on the interconnectivity of the barriers.
Practical implications
Categorization of the various barriers impeding CE uptake contributes to the body of knowledge. Also, the interrelationships among the various categorized barriers in the framework will enable construction professionals make informed decisions regarding the successful integration of CE in the industry, better appreciate the barriers that impede CE uptake and apply strategies to holistically address the barriers. This will expand current knowledge outside the narrow scope of isolated barriers.
Social implications
To the global construction industry, the review presents a list of barriers and their interrelationships that could provide implementation strategies for the uptake of CE in the industry.
Originality/value
The geographical scope of this study is not limited, and therefore encourages wide applicability of the findings to the global construction industry.
