The aim of this study is to explore the status of contemporary ethnic entrepreneurship studies in 1999‐2008 in order to map the intellectual structure of ethnic entrepreneurship research and to provide insights for future research in this field.

This study collected citation data from SSCI, resulting in a data set of 403 journal articles and 18,656 cited references. Then using co‐citation analysis, this study identified the core research themes in the ethnic entrepreneurship literature in 1999‐2008.

The results showed that contemporary ethnic entrepreneurship studies clustered around a few key research themes and their research foci have shifted from research on enclave economies, ethnic enterprises, and social embeddedness to research on immigrant entrepreneurs, immigrant networks, and transnational entrepreneurs.

With the qualification of citation and co‐citation analysis, this study profiles the changing paradigms of contemporary ethnic entrepreneurship studies and traces the development of ethnic entrepreneurship research, and thus provides important insights on future ethnic entrepreneurship research, including transnational entrepreneurs, theory refinement and theory development on ethnic entrepreneurship, as well as ethnic culture and entrepreneurship. Limitations of using SSCI data are also discussed.

The intellectual structure of ethnic entrepreneurship literature has received relatively little attention in spite that a large number of studies have been done in this field. This study provides researchers with a new way of profiling key themes and their relationships in ethnic entrepreneurship, which will help the academia and practitioners better understand contemporary ethnic entrepreneurship studies.

In this paper, the mechanical properties and corrosion resistance of CoCr alloy fabricated by selective laser melting (SLM) were studied, and the changes of performance after porcelain sintering process were also analysed. This study is to point out the relationship between the microstructure, mechanical properties and corrosion resistance of CoCr alloys prepared by SLM after porcelain sintering process. In addition, the biosafety of the sintered CoCr alloy was evaluated.

The microscopic feature changes of CoCr alloy samples after porcelain sintering process were observed by DMI 5000 M inverted metallographic microscope and Nova Nano430 FE-SEM. Moreover, phase identification and determination were conducted by X-ray diffraction (XRD) using Smartlab X-ray diffractometer. The Vickers microhardness was measured on the HVS-30 microhardness tester, and tensile tests were carried out on a CM3505 electronic universal testing machine. The corrosion resistance was tested by a classical three-point electrode system electrochemical method, then the ion precipitation was measured by using an atomic absorption spectrometer of Z2000 7JQ8024.

The XRD results indicate that the transition of γ phase (FCC) to e phase (HCP) occurs during the porcelain sintering processing of CoCr alloy. Moreover, the Vickers microhardness of the upper surface and the side surface of the CoCr alloy sample was improved by more than 36%. In addition, the ultimate strength of CoCr alloy via porcelain sintering treatment was increase to 1,395.3 ± 53.0 MPa compared to 1,282.7 ± 10.1 MPa of unprocessed CoCr alloy. However, the corrosion resistance of CoCr alloy samples decreases after porcelain sintering process.

There are few studies on the relationship of microstructure, mechanical properties and corrosion resistance of CoCr alloys prepared by SLM after porcelain sintering process. In this study, the microstructure, mechanical properties and corrosion resistance of CoCr alloy after porcelain sintering process were studied, and the biosafety of the alloy was evaluated. The research found that it is feasible to apply CoCr alloy fabricated by SLM to dental medicine after porcelain sintering process.

The purpose of this study is to examine the effects of leader mindfulness on employee safety behaviors by focusing on the mediating role of employee resilience and the moderating role of perceived environmental uncertainty.

The authors surveyed 248 employees in the high speed railway company of China in three waves with a two-week interval. Hierarchical regression analysis was used to test the hypotheses. The mediating effects and the moderated mediation effects are further tested with bias-corrected bootstrapping method.

Leader mindfulness positively affects employee safety compliance and safety participation, and these relationships were mediated by employee resilience. Perceived environmental uncertainty moderated the effects of leader mindfulness on employee resilience and the indirect effects of leader mindfulness on safety behaviors via employee resilience.

The findings elucidate the significance of leader mindfulness in promoting employee safety behaviors in the workplace.

Numerical superstition is well-known in Asian countries and can influence decision-making in many markets, from financial investment to purchasing a house. This study aims to determine the house price effects of superstition and understand if these have changed over time.

Using sales transactions of freestanding houses in Auckland, New Zealand, the authors use hedonic price analysis to investigate whether superstitious beliefs associated with lucky and unlucky house numbers affect property values.

The analysis reveals ethnic Chinese buyers in Auckland displayed superstitious home buying behaviour in the period 2003-2006 by attributing value to homes with street addresses starting or ending with the lucky number eight. However, this willing to pay higher prices for lucky numbers was not reflected in the analysis of 2011-2015 sales transactions. The disappearance of superstition price effects may indicate that ethnic Chinese in the Auckland housing market have, over time, assimilated New Zealand’s Western culture and have become less superstitious.

Unlike previous studies, the authors parse buyers into two populations of homebuyers, ethnic Chinese and non-Chinese purchasers, and model the two groups’ housing transactions independently to more accurately establish if numerical superstition influences house prices.

This study examines the motives and enabling factors regarding reverse factoring (RF) adoption in the automobile industry's supply chain.

This is a qualitative case study based on in-depth interviews with financial institutions in two countries having different statuses within the automobile industry global value chain: Mexico as a peripheral and Spain as a semi-peripheral country.

The RF is more widely deployed in Spain than in Mexico. The differences in the adoption of RF between the two countries stem from the availability of programs for suppliers at different supply levels, their efficient implementation and a robust regulatory framework, but especially from the cooperative approach adopted. The motives and enablers of RF adoption in the automobile industry can be explained under a framework of different supply chain management models. The RF programs driven by self-interest financial motives are characterized by an asymmetric distribution of benefits among supply chain participants. The RF programs that combine self-interest with cooperative motives are partially characterized by balanced benefits. In addition, they favor involvement practices and strengthen long-term relationships among supply chain participants. In this cooperative approach, trust, transparency and especially sharing information are considered relevant enablers. Finally, the specific automobile industry's features that determine RF adoption are linked to the structure and governance mode of the supply chain. The structure in terms of length – multiple supply levels – conditions the design of RF programs based on the buyer's position in the supply chain. The governance mode, particularly how the relationships are established, conditions the factors and requisites for efficient adoption of the RF programs.

This research analyzes the RF framed in the dynamics of buyer–supplier relationships and different models of supply chain management, allowing us to identify cooperation motives and their impact on RF adoption, beyond the traditional economic and financial motives highlighted by previous literature.
