This study aims to examine the double-edged effects of guanxi on opportunism and the moderating effects of legal enforceability and partner asset specificity. It thus differs from the current literature, which primarily focuses on the benevolent effects of guanxi.

Based on matched data collected from 268 sales manager and salesperson dyads, this study tested hypotheses using hierarchical regressions.

The empirical test supports the conceptual model and demonstrates two findings. First, guanxi between boundary spanners follows an inverted U-shaped relationship with inter-firm opportunism. Second, both the benefits and drawbacks of guanxi are stronger under the condition of low legal enforceability and high partner asset specificity.

The study did not untangle guanxi into different dimensions and did not investigate how firms should make trade-offs between the benefits and drawbacks of guanxi. Therefore, future research could further explore this question by using a multidimensional approach.

The study alerts managers that guanxi is a double-edged sword, so they should complement it with formal control mechanisms, particularly when they are operating in legally inefficient regions or when their partner firm’s asset specificity is high.

The study offers a more balanced view of guanxi by showing both its positive and negative effects on opportunism. It also uncovers legal enforceability and partner asset specificity as two boundary conditions that influence the curvilinear effects of guanxi on opportunism.

The purpose of this study is to develop an electromagnetic loading method for online measurement of the acoustoelastic coefficients and bus bar plane stress.

A method based on the combination of electromagnetic loading and the acoustoelastic effect is proposed to realize online measurement of acoustoelastic coefficients and plane stress. Electromagnetic loading is performed on the bus bar specimen, and the acoustoelastic coefficients and the bus bar plane stress are obtained by the ultrasonic method. An electromagnetic loading experimental platform is designed to provide electromagnetic force to the metal plate, including an electromagnetic loading module, an ultrasonic testing module and a stress simulation module.

The feasibility of the proposed electromagnetic loading method is proved by verification experiments. The acoustoelastic coefficients and plane stress measured using the electromagnetic loading method are more accurate than those measured using the traditional method.

The proposed electromagnetic loading method provides a new study perspective and enables more accurate measurement of the acoustoelastic coefficients and plane stress. The study provides an important basis for evaluating the operation status of electrical equipment.

Under the condition of small data set, a prediction model of motor magnetic field is established based on deep learning method. This paper aims to complete the magnetic field prediction quickly and accurately.

An improved Linknet model is proposed to predict the motor magnetic field. This is a digital twin technology, which can predict the function values of other points according to the function values of typical sampling points. The results of magnetic field distribution are represented by color images. By predicting the pixels of the image, the corresponding magnetic field distribution is obtained. The model not only considers the correlation between pixels but also retains the spatial information in the original input image and can well learn the mapping relationship between motor structure and magnetic field.

The model can speed up the calculation while ensuring the accuracy and has obvious advantages in large-scale calculation and real-time simulation.

Under the condition of small data set, the model can well learn the mapping relationship between motor structure and magnetic field, so as to complete the magnetic field prediction quickly and accurately. In the future, according to the characteristics of magnetic field distribution, it will lay a foundation for solving the problems of rapid optimization, real-time simulation and physical field control of electrical equipment.

By distinguishing between core business service and value-added service in mobile payment applications, this paper aims to incorporate point mechanisms (point rewarding and point exchanging) into these two separated roles of services to understand user loyalty formation. Specifically, this study aims to examine the mediating role of need satisfaction and perceived value in the relationships between point mechanisms and user loyalty.

Drawing upon self-determination theory and perceived value lens, this study develops a theoretical model that examines the mediation effects of multiple psychological outcomes on the relationships between point mechanisms (point rewarding and point exchanging) and user loyalty in the context of mobile payment. Data were collected from 731 users of a leading mobile payment application in China through an online survey. Structural equation modeling was used to analyze the hypothesized relationships.

Empirical results suggest that point rewarding enhances users’ need satisfaction of core service, whereas point exchanging increases users' perceived value of additional value-added service. Results also reveal that need satisfaction and perceived value mediate the relationships between point mechanisms (i.e. point rewarding and point exchanging) and user loyalty. In sum, the findings enhance our understanding of user loyalty formation from a dual channeling perspective.

This study informs the managers of mobile payment applications on how to build user loyalty by enhancing users' experience of core business service and value-added service through point mechanism implementation.

This study highlights the importance of both core business service and value-added service in mobile payment applications and provides new insights into the effects of point mechanisms on user loyalty by considering different service routes. Additionally, this study uncovers the mediation mechanisms of users' need satisfaction of core service and users' perceived value of additional value-added service on the two service routes, which further enrich our understanding regarding the user loyalty formation of mobile payment applications.

This study aims to investigate how social capital (e.g. cognitive and relational) influences students’ trust (e.g. cognitive and affective) as mediator variables, affecting students’ information sharing activity on Facebook.

The sample consists of 398 valid participants obtained through an online survey and using structural equation modeling (SEM) to test the research hypotheses.

The empirical results indicate that social capital has significant and positive effects on students’ trust (e.g. cognitive and affective-based trust), also mediator variables. Furthermore, the mediator variables partially mediate social capital and information sharing based on the concept of cognition-affection-behavior (CAB).

This study was limited to Indonesian students. Therefore, future study is needed to analyze across cultures and regions. It can help practitioners, regulators and researchers to observe the dynamic behavior on the impact of social capital on social media users’ activities.

Education stakeholders (e.g. lecturers and teachers) can identify the students’ goal and rational concerns to improve their social capital and trust to share information. The government as a regulator needs to support students’ activities on social media to provide updated information regarding economic and social conditions during and after the COVID-19 pandemic.

This study contributes to the literature on virtual communities. Specifically, it considers how social capital influences trust, which subsequently affects information sharing based on the CAB context among Indonesian student’ Facebook users.

This study aims to evaluate the impact of a sustainable production action on consumer trust and purchase intention by a company involved in moral transgression and also analyze the effect on consumer trust and purchase intention if a company, after green marketing, is identified as greenwashing spreader.

This quantitative nature (n = 121) study uses scale’s discriminant and convergent validity analyses, structural equation modeling and Student’s t-test.

Even for previously morally transgressive brands, actions of social legitimation, such as embracing environmental causes, positively impact consumer trust and purchase intention. However, consumers drop brand trust and purchase intention when verifying that this action was greenwashing.

Mediating or moderating variables of ecological awareness, such as religiosity or political view, were not tested.

This article combines the impact of positive, sustainable management actions for morally transgressive companies and the effects of new transgression on their sustainable management action. Thus, it aims to reduce the gap between organizational practice and management research.

This article shows that embracing society’s emerging causes and helping the world be a better place to live, moving toward the 2030 United Nations agenda, have practical repercussions for organizations.

This article contributes both to the literature and managerial implications by combining the impact of positive, sustainable management actions for morally transgressive companies and the effects of new transgression on their sustainable management action, thus reducing the gap between management research and organizational practice by unveiling the relations between sustainable actions and their perceived consequences.

The aim of the present study was to gather and review all the important properties of the Sn–Ag–Cu (SAC) solder alloy. The SAC solder alloy has been proposed as the alternative solder to overcome the environmental concern of lead (Pb) solder. Many researchers have studied the SAC solder alloy and found that the properties such as melting temperature, wettability, microstructure and interfacial, together with mechanical properties, are better for the SAC solder than the tin – lead (SnPb) solders. Meanwhile, addition of various elements and nanoparticles seems to produce enhancement on the prior bulk solder alloy as well. These benefits suggest that the SAC solder alloy could be the next alternative solder for the electronic packaging industry. Although many studies have been conducted for this particular solder alloy, a compilation of all these properties regarding the SAC solder alloy is still not available for a review to say.

Soldering is identified as the metallurgical joining method in electronic packaging industry which uses filler metal, or well known as the solder, with a melting point < 425°C (Yoon et al., 2009; Ervina and Marini, 2012). The SAC solder has been developed by many methods and even alloying it with some elements to enhance its properties (Law et al., 2006; Tsao et al., 2010; Wang et al., 2002; Gain et al., 2011). The development toward miniaturization, meanwhile, requires much smaller solder joints and fine-pitch interconnections for microelectronic packaging in electronic devices which demand better solder joint reliability of SAC solder Although many studies have been done based on the SAC solder, a review based on the important characteristics and the fundamental factor involving the SAC solder is still not sufficient. Henceforth, this paper resolves in stating all its important properties based on the SAC solder including its alloying of elements and nanoparticles addition for further understanding.

Various Pb-free solders have been studied and investigated to overcome the health and environmental concern of the SnPb solder. In terms of the melting temperature, the SAC solder seems to possess a high melting temperature of 227°C than the Pb solder SnPb. Here, the melting temperature of this solder falls within the range of the average reflow temperature in the electronic packaging industry and would not really affect the process of connection. A good amendment here is, this melting temperature can actually be reduced by adding some element such as titanium and zinc. The addition of these elements tends to decrease the melting temperature of the SAC solder alloy to about 3°C. Adding nanoparticles, meanwhile, tend to increase the melting temperature slightly; nonetheless, this increment was not seemed to damage other devices due to the very slight increment and no drastic changes in the solidification temperature. Henceforth, this paper reviews all the properties of the Pb-free SAC solder system by how it is developed from overcoming environmental problem to achieving and sustaining as the viable candidate in the electronic packaging industry. The Pb-free SAC solder can be the alternative to all drawbacks that the traditional SnPb solder possesses and also an upcoming new invention for the future needs. Although many studies have been done in this particular solder, not much information is gathered in a review to give better understanding for SAC solder alloy. In that, this paper reviews and gathers the importance of this SAC solder in the electronic packaging industry and provides information for better knowledge.

This paper resolves in stating of all its important properties based on the SAC solder including its alloying of elements and nanoparticles addition for further understanding.

The purpose of this paper is to investigate the effects of social network sites (SNS) overload on individual job performance and discontinuous usage intention.

Based on the Stressor-Strain-Outcome (SSO) framework, a research model was proposed and tested empirically. The partial least squares structural equation modeling (PLS-SEM) method was applied to data collected online through a questionnaire.

Findings highlighted that social overload is related positively to information overload and communication overload. Information overload affected only the perception of work overload, while communication overload was a significant stressor affecting work overload and dissatisfaction towards SNS. Although results revealed a positive relationship between these two strains, only dissatisfaction influenced job performance and discontinuous usage intention.

As much as SNS are a useful tool in the workplace, they can have significant drawbacks. Prior studies have investigated this dark side. However, they scantily explored the effects of SNS overload on both job performance and discontinuous usage intention. Moreover, the relationships between types of overload are understudied. This paper proposes an enrichment of the literature by validating a model of the relationships between information overload, communication overload and social overload, job performance and discontinuous usage intention. It extends prior research on SNS stressors and points out the communication overload as the main SNS stressor affecting strains in the workplace.

The purpose of this paper is to empirically test a research model that incorporated antecedents of praise feedback behaviour (fear of confrontation and incentive for reducing nuisance costs), praise feedback behaviour (deliberatively praise feedback, casual praise feedback, and true compliment feedback) and consequences (trust and repurchase intention).

A structural equation model was employed to test the relationships of the research model using survey data collected from 398 Taobao consumers.

The results showed that fear of confrontation and incentive for reducing nuisance costs had a significant positive influence on deliberatively praise feedback and true compliment feedback, respectively, and both antecedents had a significant positive influence on casual praise feedback of consumers. It also showed that trust was influenced negatively by deliberatively praise feedback, and positively by casual praise feedback and true compliment feedback. Meanwhile, deliberatively praise feedback and true compliment feedback were found to have negative and positive influences on repurchase intention, respectively.

This research was a pilot study to identify a three-dimension conceptualization of praise feedback behaviour from the perspective of customer satisfaction, and to understand positive review bias from the perspective of input processes.

This study aims to analyze and explain the characteristics and findings in previous studies of switching behavior and identifies the developments within this topic in order to improve its current understanding.

The authors construct a literature database of studies published in prominent business and management journals from 1996 to 2013 and conduct an analysis using the variables in the data fields. Furthermore, we execute meta-analysis to combine the research goals of tracing the history of customer switching behavior studies.

Satisfaction switching costs and attractiveness of alternatives are the most commonly used predictor variables to explain switching intentions. Switching costs subjective norms and interpersonal relationships moderate the relationship between switching intentions and its antecedents. Customer switching behavior in mobile telecommunication services has received a lot of attention.

This study assists researchers by examining the type and topic of these studies and the research tools and findings reported in theory. The authors ultimately identify the developmental trend in the literature on switching behavior and propose a direction for future studies.

This study clarifies the characteristics and findings of previous studies on switching intention from a literature review and improves the current understanding.
