Digital twin (DT) is an emerging technology that enables sophisticated interaction between physical objects and their virtual replicas. Although DT has recently gained significant attraction in both industry and academia, there is no systematic understanding of DT from its development history to its different concepts and applications in disparate disciplines. The majority of DT literature focuses on the conceptual development of DT frameworks for a specific implementation area. Hence, this paper provides a state-of-the-art review of DT history, different definitions and models, and six types of key enabling technologies. The review also provides a comprehensive survey of DT applications from two perspectives: (1) applications in four product-lifecycle phases, i.e. product design, manufacturing, operation and maintenance, and recycling and (2) applications in four categorized engineering fields, including aerospace engineering, tunneling and underground engineering, wind engineering and Internet of things (IoT) applications. DT frameworks, characteristic components, key technologies and specific applications are extracted for each DT category in this paper. A comprehensive survey of the DT references reveals the following findings: (1) The majority of existing DT models only involve one-way data transfer from physical entities to virtual models and (2) There is a lack of consideration of the environmental coupling, which results in the inaccurate representation of the virtual components in existing DT models. Thus, this paper highlights the role of environmental factor in DT enabling technologies and in categorized engineering applications. In addition, the review discusses the key challenges and provides future work for constructing DTs of complex engineering systems.

Transnational entrepreneurship can be considered a new stream of research where migrant entrepreneurship and international business research fields intersect. The purpose of this paper is to offer a theoretical framework to address the following research question: How do transnational entrepreneurs (TEs) develop their competitive advantage to succeed in a global market?

Based on the strategic entrepreneurship approach and dynamic capability perspective, this paper suggests a theoretical framework to extend the understanding on how TEs may develop their competitive advantage to succeed in a global market.

The suggested theoretical framework exhibits how the social ties of TEs affects their firm performance through the mediating effect of a bundle of two organizational processes (opportunity sensing and opportunity seizing) and the moderating effect of institutional distance between countries of origin and residence.

TEs should not solely focus on their ethnic social ties. That is why this paper suggests that ethnic ties in the country of origin and the country of residence (COR) may lead to higher firm performance only if systematically used alongside nonethnic ties in the COR. Furthermore, it is crucial for TEs to understand the importance of dynamic capabilities in developing and sustaining their competitive advantage.

Based on the strategic entrepreneurship approach, this paper suggests a social tie-based model of the dynamic capability to address the theoretical void in the transnational entrepreneurship literature. The linkage between social tie and performance which has been in a black box is examined in terms of how strong and weak social ties may affect different underlying processes of TEs’ dynamic capabilities differently. In contrast to the common conceptualization of institutional distance as a negative moderator in international business literature, institutional distance is theorized as a positive moderator in the suggested theoretical model of transnational entrepreneurship.

Whether older or younger entrepreneurs may be better positioned to achieve performance outcomes for their ventures is a much debated question. Here, we draw on Galenson℉s theory of creativity to propose a contingency perspective for understanding the relationship between entrepreneur age and venture performance, suggesting that a venture℉s level of innovativeness plays a moderating role. Results from a representative sample of 1,182 nascent entrepreneurs revealed mixed support for our hypotheses. While a negative relationship was found between entrepreneur age and performance for those developing “innovative” ventures, no relationship was found between entrepreneur age and performance for those developing “imitative” ventures.

This research examines stock traders' disposition effects and contrarian/momentum behavior in the Taiwan Stock Exchange (TWSE). Specifically, we first investigate disposition effects across all trader types and then examine the relationships between disposition effects, trader types, and order characteristics. Next, we explore contrarian and/or momentum behavior and analyze the relationships among the contrarian/momentum behavior, investor type, and order characteristics. Finally, the links among trader types, order characteristics, and investment performance are detected. This chapter yields the following findings. (1) Individual investors exhibit the strongest disposition effects compared to other investors. (2) Foreign investors, investment trusts, and individual investors tend to use large orders to sell loser stocks. (3) Investment trusts are inclined to be momentum traders, while individual investors tend to perform contrarian strategies. (4) Institutional aggressive and large orders perform better than individuals' orders. (5) The performance of foreign investors' selling decisions is better than that of retail investors.
