This paper aims to study a high-temperature (up to 200 °C) data acquisition and processing circuit for logging.

With the decrease in thermal resistance by system-in package technology and exquisite power consumption distribution design, the circuit worked well at high temperatures environment from both theoretical analysis and real experiments evaluation.

In thermal simulation, considering on board chips’ power consumption as additional heat source, the highest temperature point reached by all the chips in the circuit is only 211 °C at work temperature of 200 °C. In addition, the proposed circuit was validated by long time high-temperature experiments. The circuit showed good dynamic performance during a 4-h test in a 200-°C oven, and maintained a signal-to-noise ratio of 92.54 dB, a signal-to-noise and distortion ratio of 91.81 dB, a total harmonic distortion of −99.89 dB and a spurious free dynamic range of 100.28 dB.

The proposed circuit and methodology showed great potential for application in deep-well logging systems and other high-temperature situations.

Although brand alliance has become quite ubiquitous in the marketplace and attracted considerable interest amongst researchers, little research has investigated its effects on the brand equity of partners. The purpose of this paper is to demonstrate why and how brand alliance affects the brand equity of the partners in an alliance.

The hypotheses were tested by analysing the data of 260 participants in China, which were collected from an experiment.

This research draws five conclusions: the brand equity of a pre-alliance partner has a positive effect on brand alliance evaluation; product fit and brand fit amongst partners also have a positive effect on brand alliance evaluation; alliance brand evaluation has a positive impact on the brand equity of a post-alliance brand; the brand equity of a pre-alliance partner exerts a positive effect on the brand equity of a post-alliance partner; and the spillover effect of brand alliance for a weak brand is stronger than that of a strong brand in an asymmetrical brand alliance.

This research introduces brand equity into the field of brand alliance. From the perspective of consumer perception, the authors measure brand equity and provide insights for a company to effectively enhance brand equity through brand alliance. The authors explore ways to increase the brand equity of partners through brand alliance. Additionally, the authors discuss the spillover effects of the brand equity of partners in symmetric and asymmetric brand alliances.

COVID-19 affects the peer-to-peer (P2P) accommodation industry. With regard to prospect theory, individuals’ negative emotions, such as institutional distrust, are easily evoked and impede consumption intention in an environment of permeating uncertainty and risks. While existing research indicates the negative effects of institutional distrust, scant research has explored its antecedents and intervention mechanisms. This study thus aims to unveil the influencing factors and explore mitigating mechanisms of customers’ institutional distrust of P2P accommodations.

Online reviews data were used to identify the underlying critical issues. The authors developed a model to depict how institutional distrust is formed under the boundary condition of subjective norm by the results. The model was verified using a questionnaire survey. Finally, in-depth semi-structured interviews were conducted to ensure its robustness.

The external environment and internal platform effectiveness are two critical aspects affecting institutional distrust of P2P accommodations. The external environment influences institutional distrust through perceived threat, explaining the formation mechanism of customers’ institutional distrust through customers’ internal psychology. Furthermore, the authors found subjective norm moderating the effect of perceived threat on customers’ institutional distrust.

This is one of the first studies, to the best of the authors’ knowledge, to explore institutional distrust of P2P accommodations after COVID-19. The finding contributes to studies on P2P accommodation by uncovering the contingent role of subjective norm in influencing customers’ institutional distrust.

This is a pioneering study that explores the antecedents and mitigating mechanisms of institutional distrust of P2P accommodations during the new normal of COVID-19.

Previous studies have examined the emotional mechanism between perceived overqualification and knowledge hiding. Based on a relational perspective, this study aims to draw on social comparison theory to reveal the cognitive mechanism of perceived overqualification on knowledge hiding, along with the mediating effect of relational identification. This research conceptualizes perceived overqualification differentiation and reveals the moderating effect of perceived overqualification differentiation on strengthening the link between perceived overqualification and knowledge hiding.

This paper conducts two times lagged research, addresses a sample of 216 employees nested in 47 groups from technology or R&D industries and uses structural equation modeling to test an original model.

The results show that perceived overqualification positively affects knowledge hiding; relational identification mediates this relationship; perceived overqualification differentiation moderates the effect of perceived overqualification on relational identification as well the indirect effect of perceived overqualification on knowledge hiding via relational identification.

This paper shows the cognitive mechanism of perceived overqualification on knowledge hiding. Moreover, this study also extends current perceived overqualification literature from a single individual level/a dyad level to a complex team level by conceptualizing the perceived overqualification differentiation. The research findings are helpful to guide team talent management and knowledge management in business management practice.

This study aims to identify the role of this intangible cultural heritage (ICH) domain (i.e. social practices, rituals and festive events) in social representations in cross nations using the case of Mazu belief. This study also intends to compare the different social representations of the same religious belief among the regions and implies how ICH facilitates regional connections and its potential for urban tourism development.

This study uses a mix of qualitative approaches, such as desktop research, in-depth interviews, focus group discussions and participant observations. These approaches can supplement one another in discovering the cultural context of the Mazu belief and the perceived meanings of its ritual practices.

Mazu ritual practices in the four identified cities have different social representations, as explicitly expressed from the informants on different forms of celebration. Despite the differences, Mazu belief is representative in placemaking and for regional connections. Not all four cities agree on the current status as embedded in tourism development. However, the key informants show a welcoming manner to the outsiders in participating and experiencing their practices.

The research context of Mazu belief and customs can be extended to more urban cities, which practice this culture.

Different countries and regions that share the same belief can understand distinct social representations from one another. Practical collaborations can be expanded for cultural exchanges, especially the exploration of the role of religion played in boosting urban tourism development.

Mazu belief and customs is a unique cultural asset in enhancing the social representations of Chinese expatriates overseas. Its cultural practices successfully enhance the cultural exchange and social cohesion among religious communities locally and internationally.

Using a United Nations Educational, Scientific and Cultural Organization (UNESCO)-inscribed ICH item with a large audience worldwide, this study supplements the theory of social representations in exploring the intangible cultural assets and highlights the role of ICH in urban tourism and regional and city planning.

Underpinned by the attraction-selection-attrition theory, this paper aims to investigate the impact of entrepreneurship on an individual’s expected retirement age and explore how job satisfaction and expected retirement financial insufficiency (ERFI) as key factors can explain that.

A framework including direct and indirect relationships among key factors is empirically tested by using a pooled data sets consists of 13,420 individuals from the UK Household Longitudinal Survey, the analysis uses the entropy balance matching method and combined with quasi-bayesian monte Carlo method and hierarchy regressions to enhance the robustness of results.

The research finds entrepreneurs plan to retire later than organizational employees. In addition, a strong mediating impact of job satisfaction and moderating role of ERFI on the relationship between entrepreneurship and expected retirement age is verified.

The theoretical perspective and findings offer a novel insight into the research on entrepreneurs’ decision of retirement. The findings suggest entrepreneurs as crucial policy stakeholders contribute to retirement deferment should be valued. Effective interventions could be delicately designed in the future to unleash the potential of entrepreneurship in dealing with aging challenges.

The new Silk Road provides cross-border-e-commerce firms with an opportunity to widen their markets. Under this circumstance, the preference recognition of countries and inventory allocation among overseas warehouses both become critical issues to solve. Three Chinese smartphone brands, including HTC, Huawei, and MI, are selected in this chapter for their relatively enormous sales. DHgate and AliExpress websites are chosen as platforms to analyze the sales for data availability. This chapter first depicts key features of the sales and then, based on which, divide countries into several groups according to their preference for phones by cluster analysis. Then, based on the results of cluster analysis, this chapter further models the inventory assignment among the seven major overseas warehouses that were built by AliExpress in 2015. The results show that the HTC seems to be pursuing the “high value with high price” strategy, while the other two companies seem to be pursuing a hybrid strategy of “low-price” strategy and “high value with low price” strategy. This chapter also provides an assignment pattern of inventory among the overseas warehouses based on the real data of sales and costs.

The purpose of this paper is to investigate dynamics of causal interactions and financial risk contagion among BRICS stock markets under rare events.

Two methods are adopted: The new causal inference technique, namely, the Liang causality analysis based on information flow theory and the dynamic causal index (DCI) are used to measure the financial risk contagion.

The causal relationships among the BRICS stock markets estimated by the Liang causality analysis are significantly stronger in the mid-periods of rare events than in the pre- and post-periods. Moreover, different rare events have heterogeneous effects on the causal relationships. Notably, under rare events, there is almost no significant Liang's causality between the Chinese and other four stock markets, except for a few moments, indicating that the former can provide a relatively safe haven within the BRICS. According to the DCIs, the causal linkages have significantly increased during rare events, implying that their connectivity becomes stronger under extreme conditions.

The obtained results not only provide important implications for investors to reasonably allocate regional financial assets, but also yield some suggestions for policymakers and financial regulators in effective supervision, especially in extreme environments.

This paper uses the Liang causality analysis to construct the causal networks among BRICS stock indices and characterize their causal linkages. Furthermore, the DCI derived from the causal networks is applied to measure the financial risk contagion of the BRICS countries under three rare events.

This paper comprehensively and systematically reviews and critiques the product eco-design practice in green supply chain management studies. It seeks to explore drivers, barriers and initiatives of eco-design practice with a specific emphasis on China in comparison to non-China countries.

This paper adopts a systematic literature review approach. It also uses a conceptual thematic landscape of the global eco-design practice along supply chains to critically evaluate published studies. The Web of Science™ Core Collection database is used as the source.

Results show that although common factors exist, China exhibits a higher number of barriers, leading to an overall lag in eco-design adoption. China’s advantage lies in pressing market demand, actively engaged human resources and a cooperative culture. Alternatively, non-China countries demonstrate their relative superiority in eco-design tools, knowledge and innovation. Findings also indicate stakeholders simultaneously act as the three roles of eco-design practice in all countries, so do environmental regulations in China.

A thematic framework is introduced that can be used to further investigate and identify research opportunities. This study aids practitioners take stock of current eco-design management issues. It also includes pertinent recommendations on international eco-design performance improvement. It especially provides significant insights into successful eco-design implementation to green supply chains in China.
