Abstract

Purpose

The purpose of this paper is to develop a new finite difference method for solving the seismic wave propagation in fluid-solid media, which can be described by the acoustic and viscoelastic wave equations for the fluid and solid parts, respectively.

Design/methodology/approach

In this paper, the authors introduced a coordinate transformation method for seismic wave simulation method. In the new method, the irregular fluid–solid interface is transformed into a horizontal interface. Then, a multi-block coordinate transformation method is proposed to mesh every layer to curved grids and transforms every interface to horizontal interface. Meanwhile, a variable grid size is used in different regions according to the shape and the velocity within each region. Finally, a Lebedev-standard staggered coupled grid scheme for curved grids is applied in the multi-block coordinate transformation method to reduce the computational cost.

Findings

The instability in the auxiliary coordinate system caused by the standard staggered grid scheme is resolved using a curved grid viscoelastic wave field separation strategy. Several numerical examples are solved using this new method. It has been shown that the new method is stable, efficient and highly accurate in solving the seismic wave equation defined on domain with irregular fluid–solid interface.

Originality/value

First, the irregular fluid–solid interface is transformed into a horizontal interface by using the coordinate transformation method. The conversion between pressures and stresses is easy to implement and adaptive to different irregular fluid–solid interface models, because the normal stress and shear stress vanish when the normal angle is 90° in the interface. Moreover, in the new method, the strong false artificial boundary reflection and instability caused by ladder-shaped grid discretion are resolved as well.

Abstract

Purpose

This study focuses on how entrepreneurial bricolage (EB) drives both competitive advantage (CA) and sustainability performance (SP).

Design/methodology/approach

Relying on structural equation modeling, data were collected from 200 small and medium-sized enterprise (SME) manufacturers in Ghana.

Findings

The results indicate that EB drives both CA and SP positively. SL positively moderated the relationship between EB and CA, while the moderating role of SL in the relationship between EB and SP was not supported.

Originality/value

The study concludes that EB can enhance SP, a notion prior study grossly overlooked.

Abstract

Purpose

Brand microblogs have been adopted as a new approach to promote products or services and maintain relationships with consumers for companies, but literature on why consumers are willing to participate on these microblogs is still relatively limited. The purpose of this study is to examine factors affecting consumers’ participation on brand microblogs and then indicate the underlying mechanism of this process based on elaboration likelihood model (ELM), commitment–trust theory and social presence.

Design/methodology/approach

An online survey was conducted in China to investigate consumers who followed brand microblogs. A total of 380 valid responses were collected, and the data were analyzed by the partial least squares structural equation modeling to assess the proposed research model.

Findings

The findings show that argument quality and source credibility of a brand microblog are two important factors that enhance consumers’ community commitment and trust toward the microblog, which, in turn, promote their participation intention. In addition, social presence has a moderating effect on the relationship between trust toward brand microblog and participation.

Originality/value

This study extends the understanding regarding consumers’ information adoption processes in brand microblogs from both central and peripheral routes based on ELM. Besides, the role of trust in affecting consumers’ participation and community commitment in the context of brand microblog has been examined from a more detailed perspective. Finally, this paper better reveal the role of social presence in brand communities by focusing on its moderating effect on the relationship between commitment–trust and consumers’ participation. These findings can provide entrepreneurs with insights into strengthening consumers’ participation and operating their brand microblogs in the long-term.

Abstract

Purpose

It is unclear what constitutes the tourism live streaming (TLS) servicescape and how it affects users' travel intention (TI). The study aims to explore the composition of the TLS servicescape, the influence mechanism of the TLS servicescape on users' TI and the formation of users' TI.

Design/methodology/approach

Based on stimulus organism response theory (SOR), we develop a mediation model to explore the influence of TLS servicescape on users' TI. This study collected data from 432 Chinese TLS users through an online questionnaire, and we used the structural equation model and the SPSS PROCESS macro to test the proposed model. In addition, we tested the variable relationships using fuzzy-set qualitative comparative analysis (fsQCA).

Findings

TLS servicescape is a second-order variable that can be categorized into physical element (PE), social element (SOE), symbolic element (SYE) and natural element (NE). TLS servicescape influences TI by affecting social presence (SP) and customer engagement (CE). The fsQCA reveals seven combinations of PE, SOE, SYE, NE, SP and CE that form a high TI for TLS users.

Originality/value

Using multiple data analysis methods, the study emphasizes the significance of the TLS servicescape for TLS. It explores how to evoke users' TI in TLS and provides a reference for TLS marketing.

Abstract

Purpose

The purpose of this paper is to explore the influencing mechanism of coaching leadership (CL) on employee voice behavior (VB) based on cognitive-affective system theory of personality (CAPS). Specifically, the study intends to build a model of psychological security (PS) and openness to change (OC) that mediate the relationship between CL and employee VB at an individual-level and group-level from cognitive-affective dual perspective.

Design/methodology/approach

CL, employee VB, PS and OC were assessed in an empirical study based on a supervisor–subordinate dyads sample of 287 employees and 72 team leaders from enterprises in Southern China.

Findings

From CAPS theory perspective, the authors found that CL promotes employee VB and that PS and OC mediate the relationship between CL and VB.

Practical implications

Results underscore the importance of encouraging managers to engage in CL behaviors, which are conductive to enhancing employee PS and OC thereby improving employee VB. These results also highlight the significance of managerial attention to a secure voice atmosphere and the improvement of employees’ affective commitment to organizational change.

Originality/value

The research findings provide a significant contribution to the literature in that it shows PS and OC as crucial dual mediating mechanism through which CL influences VB. Moreover, this paper is one of the few studies answering the call to examine the effect of leadership at multiple levels.
