The purpose of this paper is to summarize the latest research of BIM adoption in construction engineering and management (CEM) and propose research directions for future scholarly work. During the recent decade, building information modeling (BIM) has gained increasing applications and research interest in the construction industry. Although there have been review-based studies that summarized BIM-based research in the overall architecture, engineering and construction (AEC) area, there is limited review that evaluates the current stage of BIM-based research specifically in the CEM sub-area.

CEM falls into the scope of AEC. It involves construction-related tasks, activities and processes (e.g. scheduling and cost estimates), issues (e.g. constructability), as well as human factors (e.g. collaboration). This study adopted a holistic literature review approach that incorporates bibliometric search and scientometric analysis. A total of 276 articles related to BIM applied in CEM were selected from Scopus as the literature sample for the scientometric analysis.

Some key CEM research areas (e.g. CEM pedagogy, integrated project delivery, lean and off-site construction) were identified and evaluated. Research trends in these areas were identified, and analyses were carried out with regard to how they could be integrated with BIM. For example, BIM, as a data repository for ACE facilities, has substantial potential to be integrated with a variety of other digital technologies, project delivery methods and innovative construction techniques throughout the whole process of CEM.

As BIM is one of the key technologies and digital platforms to improve the construction productivity and collaboration, it is important for industry practitioners to be updated of the latest movement and progress of the academic research. The industry, academics and governmental authorities should work with joint effort to fill the gap by first recognizing the current needs, limitations and trends of applying BIM in the construction industry. For example, it needs more understanding about how to address technical interoperability issues and how to introduce the integrated design and construction delivery approach for BIM implementation under the UK BIM Level 2/3 framework.

This study contributed to the body of knowledge in BIM by proposing a framework leading to research directions including the differences of BIM effects between design-bid-build and other fast-track project delivery methods; the integration of BIM with off-site construction; and BIM pedagogy in CEM. It also addressed the need to investigate the similarities and differences between academia and industry toward perceiving the movement of BIM in construction field work.

The purpose of this paper is to investigate how boundary-spanning search affects sustainable competitive advantage under the conditions that competitors also search and to test the moderating role of knowledge integration capability.

This paper classifies boundary-spanning search into proactive search and responsive search by considering competition and develops a theoretical model in which knowledge integration capability moderates the effects of proactive and responsive searches on sustainable competitive advantage. Empirical analyses were conducted on the data of 245 Chinese advanced manufacturing firms.

The results show that proactive and responsive searches have inverted U-shaped relationships with sustainable competitive advantage. Moreover, the relationships between proactive and responsive searches and sustainable competitive advantage are moderated by knowledge integration capability. Specifically, as knowledge integration capability increases, the inverted U-shaped relationship between proactive search and sustainable competitive advantage becomes flatter, whereas the inverted U-shaped relationship between responsive search and sustainable competitive advantage becomes almost linear.

This paper enriches the research of boundary-spanning search by considering competition and uncovers how boundary-spanning search affects sustainable competitive advantage under the conditions that competitors also search. Furthermore, this paper sheds light on that the effects of proactive and responsive searches on sustainable competitive advantage are even more complex than inverted U-shaped patterns and provides a contingent viewpoint to deeply understand the relationship between boundary-spanning search and sustainable competitive advantage.

The purpose of this paper is to explore the influencing mechanism of servant leadership on employee and team creativity based on efficacy theory. Specifically, the study intends to develop a model of efficacy beliefs that mediates the relationships between servant leadership, employee creativity, and team creativity at different levels. The study also aims to investigate the moderating effects of team power distance on the relationships between servant leadership, creative self-efficacy, and team efficacy at both individual and team levels.

Servant leadership, employee creativity, creative self-efficacy, team creativity, team efficacy, and team power distance were assessed in an empirical study based on a sample of 466 employees and 83 team leaders from 11 banks in China.

From efficacy theory perspective, this paper finds that servant leadership promotes employee creative self-efficacy and team efficacy, which enables the simultaneous promotion of employee creativity and team creativity. Team power distance also moderates the relationship between servant leadership and team efficacy.

The results suggest that it is important to encourage managers to engage in servant leader behaviors, which is conductive to enhancing employees’ self-efficacy beliefs and thereby improving creative outcomes of employees. The results are also helpful for managers to enhance their understanding of the differences in cultural values in management behavior and the effects of behavior on team efficacy.

The research findings provide a significant contribution to the literature in that it shows self-efficacy as a crucial mediating mechanism through which servant leadership influences creativity at individual and team levels. Moreover, the findings support the view that power distance is an important contextual factor that affects the influencing mechanism of servant leadership on team creativity. Furthermore, this paper is one of the few studies answering the call to examine the effect of leadership at multiple levels.

The purpose of this paper is to present a simple and effective method to search the optimal turn-on and turn-off angles on-line for the control of the switched reluctance motor (SRM). The optimal turn-on and turn-off angles are defined as the ones that can meet torque production requirements with minimum copper loss.

The optimal turn-on and turn-off angles are first defined based on the analysis of the SRM losses and torque production principles. Then the algorithm for optimal angles searching is developed, and the searching parameters are determined through analytical computation. The optimal angles are approached on-line with iterative process. Simulation and experiments are finally performed to verify the proposed method.

The presented method can meet torque production requirements while copper loss is minimized. The optimal turn-on and turn-off angles are generally approached within five phase cycles for most of the SRM operation modes. Furthermore, the SRM drive system using the presented method exhibits good dynamics during starting and sudden load operations.

The presented method is simple, and implementation of it is easy. It is an eligible candidate for industrial applications where energy conversion efficiency is crucial.

The optimal turn-off angle definition that considers both torque production and copper loss minimization is proposed. The turn-on and turn-off angles are searched independently on-line with little SRM geometrical information. The searching steps are derived through analytical computation and qualitative analysis so that both the searching speed and algorithm convergence are balanced.

This study investigates the dynamic relationships among trading behaviors of different investor groups (foreigners, domestic institutions and domestic individuals), stock returns and sovereign CDS (Credit Default Swap) spreads in Korea.

We employ the VAR (Vector autoregression) model to examine the dynamic relationships between CDS spread changes, stock returns and investors' behavior in the stock market.

The CDS spread change (stock return) declines (rises) in response to shocks to net foreign flows into the stock market on the same day. Foreigners buy stocks more intensely one day after an increase in the stock return, but they do not respond to CDS spread changes. Domestic individuals trade in the opposite direction of foreigners in response to shocks to both stock returns and CDS spread changes on the same day. Positive net stock purchases of domestic institutions (individuals) predict positive (negative) stock returns and negative (positive) CDS spread changes next day.

This study extends prior studies by examining how different investor groups' trading behaviors in the stock market are associated with not only the stock market but also a closely related market (CDS market). Prior empirical studies on the relation between the stock and CDS markets do not pay attention to possible heterogeneity in trading behavior across different types of investors in the stock market.

The purpose of this paper is to examine the relationship between price movements of target firms’ stocks and behaviors of local individual, local institutional and foreign investors in trading target firms’ stocks around mergers and acquisitions announcements in Korea.

This study uses event study methodology and cross-sectional regressions for abnormal returns.

Results reveal that the average abnormal return becomes significantly positive three days prior to the announcement date and becomes insignificant after the announcement date. Results also show that local individual investors tend to sell more intensely prior to announcements for target firms with larger wealth effects. In contrast, foreign investors tend to buy target stocks with larger wealth effects more intensely prior to the announcement date, and then they sell them more intensely in the post-announcement period.

This paper provides evidence that foreign investors are able to identify target stocks with large wealth effects prior to the announcement date and they realize short-term profits by selling them following the announcement.

The track impedance is one of the most important parameters in designing the track circuit which is widely used in the railway signal control system to detect the presence of a train. This paper aims to calculate the ballastless track impedance by taking account of the influence of reinforcement bars.

This paper proposes a two-step decomposition approach to calculate the ballastless track impedance. The basic idea is evaluating the track impedance without the reinforcement bars by using two-dimensional (2D) finite element method (FEM), and the incremental impedance, because of the reinforcement bar, is calculated by the partial element equivalent circuit (PEEC) method.

The numerical examples show that the proposed approach can guarantee the accuracy and largely reduce the computing time, at least 20 times, compared with the direct three-dimensional (3D) FEM method.

The study provides a fast approach to calculate the ballastless track impedance. However, compared with the 3D FEM method, the results are less accurate because of the approximation and assumption adopted in the method. A future study should pay more attention to improve accuracy of the model.

A fast approach is proposed to calculate the ballastless track impedance taking account of the influence of the reinforcement bars. The computing time can be largely reduced by using the method. With the proposed approach, the influence of insulation of the reinforcement bars on track impedance can be analyzed.

This study examines the bid/ask spread and its components in the KOSPI200 options market under the framework of the cross-market model, which utilizes the order flow information of both KOSPI200 futures and options markets. We also compare the results by the single-market model (MRR model; Madhavan et al., 1997) and by the cross-market model (Ryu (2011)’s extension). This comparison suggests that the cross-market approach can mitigate the underestimation of the permanent spread component of OTM options and the overestimation of the component of ITM options, which are often detected when we directly apply the single market model into the KOSPI200 options market where the ITM options are relatively illiquid while the OTM options are extremely liquid. We also find that the effect of the order flow information of the futures market on the option spread and its permanent spread component will vary depending on the option moneyness and the intraday time period. This implies that the order flow of the futures market has more significant effects if the degree of informed trading is relatively high.

The current study, which is based on social learning theory and social cognitive theory, intends to investigate the impact of entrepreneurial leadership on employee creativity at both the individual and team levels. In particular, the authors predict a mediating mechanism at both levels: employees’ entrepreneurial self-efficacy. Further, the authors consider whether the climate of support for innovation is a contextual element affecting the relationship between employees’ perceptions of entrepreneurial leadership and their own entrepreneurial self-efficacy.

The research hypotheses were tested using multilevel structural equation modeling on 191 employees nested in 49 entrepreneurial ventures in China.

The results indicated that entrepreneurial leadership positively correlates with employee creativity at individual level. Moreover, this study found that individual followers’ entrepreneurial self-efficacy partially mediates the association between individual perceptions of entrepreneurial leadership and employee creativity, whereas team members’ entrepreneurial self-efficacy fully mediates the association between team members’ perceptions of supervisors’ entrepreneurial leadership and employee creativity. Further, this research demonstrates the role of team-level climate of support for innovation as a boundary condition that strengthens the effect of entrepreneurial leadership on individual entrepreneurial self-efficacy.

Considering entrepreneurial self-efficacy to be a type of entrepreneurial context-specific self-efficacy, this study presents one of the first empirical examples of the mediating function of entrepreneurial self-efficacy in the association between entrepreneurial leadership and employee creativity. Additionally, this research demonstrates the role of team-level climate of support for innovation as a boundary condition that strengthens the effect of entrepreneurial leadership on individual entrepreneurial self-efficacy. Further, this study provides a methodological contribution by simultaneously assessing all three variables of the mediation process at the individual and team levels: entrepreneurial leadership, entrepreneurial self-efficacy and employee creativity.

This paper aims to put forth a model that accounts for the effect of servant leadership on employee creativity from a social identity perspective. Specifically, this paper aims to examine team identification as the mediating mechanism by which servant leadership influence employee creativity. This paper also intends to investigate the moderating influences of horizontal and vertical collectivism on the effectiveness of servant leadership on follower team identification.

Servant leadership, team identification, collectivism (consisted of horizontal and vertical collectivism) and employee creativity were assessed in an empirical study based on a sample of 451 employees from 11 banks in China.

Drawing on social identity theory, this study found that follower team identification partially mediates the relationship between servant leadership and employee creativity. In addition, results showed that horizontal collectivism moderates the relationship between servant leadership and follower team identification; the relationship was more positive when horizontal collectivism was high, rather than low; vertical collectivism also moderates the relationship between servant leadership and follower team identification; the relationship was more positive when vertical collectivism was low, rather than high. However, results of this study indicated that the moderated mediation effects of team identification on the relationship between servant leadership and employee creativity are nonsignificant.

First, this research affirmed the need to promote servant leadership in employment settings. Second, managers’ understandings of the instrumental role of servant leadership in showing interpersonal acceptance, offering encouragement and support and expressing trust would prove to be valuable because it could enhance employee creativity. Finally, the findings from this study should help managers gain a better understanding of the contextual factors.

The first contribution of the current study was to identify team identification as an important psychological process that can link servant leadership to employee creativity. Another important contribution of the current research was the identification of the boundary conditions (e.g. horizontal and vertical collectivism).
