Abstract
Purpose
Excellent obstacle surmounting performance is essential for the robotic vehicles in uneven terrain. However, existing robotic vehicles depend on complex mechanisms or control algorithms to surmount an obstacle. Therefore, this paper aims to propose a new simple configuration of an all-terrain robotic vehicle with eight wheels including four-swing arms.
Design/methodology/approach
This vehicle is driven by distributed hydraulic motors which provide high mobility. It possesses the ability to change the posture by means of cooperation of the four-swing arms. This ensures that the vehicle can adapt to complex terrain. In this paper, the bionic mechanism, control design and steering method of the vehicle are introduced. Then, the kinematic model of the center of gravity is studied. Afterward, the obstacle surmounting performance based on a static model is analyzed. Finally, the simulation based on ADAMS and the prototype experiment is carried out.
Findings
The experiment results demonstrate that the robotic vehicle can surmount an obstacle 2.29 times the height of the wheel radius, which verifies the feasibility of this new configuration. Therefore, this vehicle has excellent uneven terrain adaptability.
Originality/value
This paper proposes a new configuration of an all-terrain robotic vehicle with four-swing arms. With simple mechanism and control algorithms, the vehicle has a high efficiency of surmounting an obstacle. It can surmount a vertical obstacle 2.29 times the height of the wheel radius.

Abstract
Purpose
Online service brand communities (OBCs) are an essential services marketing channel and relationship marketing tool, in which social capital (SC) is a critical success factor. Underpinned in social identity and social exchange theories, this paper aims to explore the effects of SC on customer brand engagement (CBE), considering the roles of collective psychological ownership (CPO), customer citizenship behaviour (CCB) and perceived community support (PCS).
Design/methodology/approach
The research model was tested using survey data from 256 participants; 137 from the Xiaomi Community and 119 from the Huawei Fan Club. Partial least squares-structural equation modelling analysis was used.
Findings
SC drives CBE. CPO and CCB are important mediators, whilst PCS is an important moderator.
Practical implications
Brand marketers need to foster SC in OBCs to achieve the maximum level of customer engagement. The authors provide recommendations as to how to build structural, relational and cognitive SC, as well as CPO, CCB and PCS. In short, brand marketers need to foster an interactive, empowering and supportive environment.
Originality/value
The authors further service research around the humanisation of technology. Specifically, OBCs are social spaces for brands and customers, and a key enabler of relationship marketing principles, such as CBE. The authors test the roles of structural, cognitive and relational SC in engagement in OBCs, through CPO and CCB. This holistic picture of engagement in OBCs is an important foundation for future service research.

Abstract
Purpose
The purpose of this study is to adopt the perspective of congruence to explore how organizational unlearning facilitates knowledge transfer in cross-border mergers and acquisitions (M&A).
Design/methodology/approach
Drawing on the congruence theory, this study built a theoretical model and examined it with survey data from 212 firms in China.
Findings
Organizational unlearning has no direct influence on knowledge transfer. In contrast, it promotes knowledge and routine compatibility that facilitate knowledge transfer. Routine and knowledge compatibility have different mechanisms on knowledge transfer. Specifically, the higher routine compatibility, the more effective is knowledge transfer. When knowledge compatibility is at a medium level, the effectiveness of knowledge transfer is optimal.
Practical implications
Firms should regard organizational unlearning as a crucial facilitator to knowledge and routine compatibility that promote knowledge transfer.
Originality/value
This study provides a specific understanding of the relationships between organizational unlearning and knowledge transfer by focusing on knowledge and routine compatibility as the crucial links, and enriches existing literature regarding knowledge transfer.

The purpose of this paper is to test a multilevel framework to further explicate how team leaders’ authentic leadership is related to their followers’ individual creativity.
Abstract
Purpose
The purpose of this paper is to test a multilevel framework to further explicate how team leaders’ authentic leadership is related to their followers’ individual creativity.
Design/methodology/approach
This study is based on a questionnaire survey/analysis of analyses of multisource and lagged data from 63 team leaders and 428 followers in Taiwan.
Findings
The findings demonstrated that leader-member exchange (LMX) and team psychological safe climate mediated the positive relationship of authentic leadership on followers thriving at work. Furthermore, employee thriving at work sequentially mediated the positive relationship between authentic leadership and employee creativity. The author also found that indirect relationship of LMX with employee creativity through thriving at work was stronger when authentic leadership was higher.
Originality/value
The authors contribute to the existing understanding that authentic leadership relates to individual creativity through three multilevel mechanisms: leaders modeling their authenticity to develop and maintain their dyad-level exchange relationships with their followers (LMX), motivating the team, captured by team-level psychological safe climate and its members, reflected by employee-level thriving at work, and facilitating the relationship between LMX and employee thriving at work.

Abstract
Purpose
From the perspective of social networks and knowledge networks, this study aims to empirically examine an updated four-dimension networking capability (NC) construct and test the relationships between it and innovation strategies through knowledge application activities in the context of Chinese manufacturing firms.
Design/methodology/approach
Data analysis is conducted on a quantitative survey of 219 manufacturing firms in China with a mixed method of partial least squares structural equation modeling and fuzzy-set qualitative comparative analysis.
Findings
The results indicate that knowledge assimilation application (KAA) and knowledge transformation application (KTA) fully mediate the relationships between NC and ambidextrous innovation strategies. KAA has a stronger association with exploitative innovation (EL) than with exploratory innovation (ER), and KTA has a stronger association with ER than with EL.
Research limitations/implications
The authors develop the conceptualization of NC and examine its role in knowledge application activities within a firm. Further, the authors adopt an alternative perspective to highlight the importance of KAA and KTA in mediating the relationships between NC and exploratory and exploitative innovation strategies.
Practical implications
The findings indicate that firms should build NC based on their knowledge requirements and knowledge network structure. Additionally, managers should possess in-depth insights regarding an effective knowledge application toward different types of external knowledge from partners. More specific, firms are more likely to conduct KAA for a high degree of knowledge relatedness, while for a low degree of knowledge relatedness, firms are more likely to conduct KTA.
Originality/value
The authors provide a novel alternative insight into knowledge application activities. From the perspective of knowledge networks, the authors argue that there are two distinct and parallel activities (i.e. KAA and KTA). The authors empirically examined the mediating roles of KAA and KTA in the NC–ambidextrous innovation strategies relationships as well as enriched the literature on their relationships.

Abstract
Purpose
This study examines the effect of political networking capability (PNC) and strategic capability on exploratory innovation/exploitative innovation through the mediation of absorptive capability (AC).
Design/methodology/approach
Using empirical survey data collected from 153 traditional manufacturing firms (TMFs) in China, the authors apply partial least squares structural equation modeling (PLS-SEM) combined with mediation analyses to test hypotheses.
Findings
PNC has a higher impact on exploratory innovation than exploitative innovation through AC. The authors thus provide novel empirical insights into independent variables of firms' ambidextrous innovation and their implementation mechanisms.
Research limitations/implications
The authors highlight a unique situation of China and contribute to the literature on PNC and AC. The findings demonstrate that AC plays an important role in configuring government-obtained external resources into new products, thus influencing ambidextrous innovation strategic decisions.
Practical implications
TMFs' executives should enhance PNC to obtain more resources to conduct exploratory and exploitative innovation. Government officials and policymakers should strengthen the supervision of TMFs' innovation activities and adopt effective measures to ensure that TMFs could conduct more exploratory innovation as governments expected.
Originality/value
This study provides new insights by bridging research gaps in the literature and advances the insights of how TMFs' PNC/strategic capability directly and indirectly fosters exploratory and exploitative innovation via the mediating role of AC in China.
