Abstract
Purpose
As the strategy of 5G new infrastructure is deployed and advanced, 5G-R becomes the primary technical system for future mobile communication of China’s railway. V2V communication is also an important application scenario of 5G communication systems on high-speed railways, so time synchronization between vehicles is critical for train control systems to be real-time and safe. How to improve the time synchronization performance in V2V communication is crucial to ensure the operational safety and efficiency of high-speed railways.
Design/methodology/approach
This paper proposed a time synchronization method based on model predictive control (MPC) for V2V communication. Firstly, a synchronous clock for V2V communication was modeled based on the fifth generation mobile communication-railway (5G-R) system. Secondly, an observation equation was introduced according to the phase and frequency offsets between synchronous clocks of two adjacent vehicles to construct an MPC-based space model of clock states of the adjacent vehicles. Finally, the optimal clock offset was solved through multistep prediction, rolling optimization and other control methods, and time synchronization in different V2V communication scenarios based on the 5G-R system was realized through negative feedback correction.
Findings
The results of simulation tests conducted with and without a repeater, respectively, show that the proposed method can realize time synchronization of V2V communication in both scenarios. Compared with other methods, the proposed method has faster convergence speed and higher synchronization precision regardless of whether there is a repeater or not.
Originality/value
This paper proposed an MPC-based time synchronization method for V2V communication under 5G-R. Through the construction of MPC controllers for clocks of adjacent vehicles, time synchronization was realized for V2V communication under 5G-R by using control means such as multistep prediction, rolling optimization, and feedback correction. In view of the problems of low synchronization precision and slow convergence speed caused by packet loss with existing synchronization methods, the observer equation was introduced to estimate the clock state of the adjacent vehicles in case of packet loss, which reduces the impact of clock error caused by packet loss in the synchronization process and improves the synchronization precision of V2V communication. The research results provide some theoretical references for V2V synchronous wireless communication under 5G-R technology.

Abstract
Purpose
Despite corporate communications having an immense impact on corporate success, there is a lack of dedicated techniques for their management and visualization. A potential strategy is to apply business process management (BPM) approach with business process model and notation (BPMN) modeling techniques.
Design/methodology/approach
The goal of this study was to gain empirical insights into the cognitive effectiveness of BPMN-based corporate communications modeling. To this end, experimental research was performed in which subjects tested two modeling notations – standardized BPMN conversation diagrams and a BPMN extension with corporate communications-specific concepts.
Findings
Standard conversation diagrams were demonstrated to be more time-efficient for designing and interpreting diagrams. However, the subjects made significantly fewer mistakes when interpreting the diagrams modeled in the BPMN extension. Subjects also evolved positive perceptions toward the proposed extension.
Practical implications
BPMN-based corporate communications modeling may be applied to organizations to depict how formal communications are or should be performed consistently, effectively and transparently by following and integrating with BPM approaches and modeling techniques.
Originality/value
The paper provides empirical insights into the cognitive effectiveness of corporate communications modeling based on BPMN and positions the corresponding models into typical process architecture.

Abstract
Interest in leadership research began in early 20th century; yet the definition of leadership has been blurred, and contested. This is evident in countless leadership theoretical perspectives, models and frameworks that have been emerging and which make it challenging for aspiring leaders to learn and develop especially in this volatile age. Higher institutions, to future proof their undergraduates, have responded to this critical need, by offering either specialized leadership content or leadership communication courses, or focusing more on one discipline than the other. However, a more holistic approach, underpinned by behaviorist and constructivist theories of teaching and learning, that prepares leaders for these turbulent times is urgently needed. This teaching experience discusses the evolution, process and impact of a collaborative effort between two disciplines, Information Systems (IS) leadership content and IS leadership communication skills. University administered anonymous qualitative and quantitative post module evaluation reports show that while some students see the relevance and transference of leadership knowledge and skills to other domains, other do not see the need to learn about these skills before they begin their professional career. These findings offer valuable potholes to avoid and insights for future leadership training efforts.

Abstract
Purpose
This research is motivated by the increasing need for international interactions during the gradual recovery of the tourism industry. By recognizing the paucity of research on cultural closeness and accommodation categories, this research aims to illuminate the influencing mechanisms of psychological closeness and travelers’ willingness to book an accommodation-sharing property while booking an accommodation.
Design/methodology/approach
The authors employ a mixed-methods approach, including an experiment and semistructured interviews.
Findings
Results show that hosts’ higher cultural identity congruence leads to travelers’ higher willingness to book an accommodation-sharing property. Psychological closeness mediates the positive effect of cultural identity congruence on travelers’ willingness to book. The authors further explore the moderating role of room types (entire room vs. private room) and find that the mediation effect is stronger for booking an entire room.
Originality/value
The current research underlines the importance of cultural identity congruence and accommodation type on travelers’ willingness to book an accommodation-sharing property and psychological closeness.

Abstract
Using and understanding social media in the context of networked publics enhances crisis communication. This chapter describes models and ideas for integrating social media into the communication strategies of rescue organisations. The authors develop their recommendations for the use of social media by these organisations from both a summary and comparison of communication processes during the 2013 Central European floods in Austria, and from the perspective of an organisation actively using social media in the chosen model region of Alkoven. The chapter presents basic recommendations, recommendations inspired by content strategy and recommendations based on web and social media literacy in order to support the further development of crisis communication in the digital age.

Abstract
It is common for professionals in technical and science-related careers to interact with colleagues and the general public frequently in their daily work. However, most do not receive any education or practice developing interpersonal skills. Thus, these professionals may struggle to create positive interactions, especially while in leadership roles or interacting with stakeholders or clientele. We worked with the Wildlife Services National Training Academy to develop and deliver a half-day training on leadership competencies including emotional intelligence, power and influence, and conflict management. This application brief describes the training, including learning activities implemented, and reports evaluative feedback from participants and the workshop developers and facilitator. Recommendations for implementing similar leadership development programming for technical audiences is included.

Abstract
Purpose
This study aims to illuminate the contribution of neurophysiological techniques in the field of marketing and consumer decision-making and to highlight avenues and research questions that marketing researchers can take advantage of from neuroscience and psychology to inform marketing phenomena.
Methodology
The authors first reviewed the roots and definition of consumer neuroscience. Then, the authors outlined the main characteristics of the most commonly used neurophysiological tools (namely, skin conductance, facial electromyography, electrocardiogram, eye-tracking, electroencephalography, functional magnetic resonance imaging, functional near-infrared spectroscopy, magnetoencephalography and transcranial magnetic stimulation) with a special emphasis on their advantages and weaknesses. Finally, the authors propose the development of research lines that could be implemented by marketing researchers with an appropriate application and understanding of tools and theories of neuroscience and psychology.
Findings
The authors propose research questions to be addressed within four thematic areas: opportunities in product decisions (predicting product purchasing decisions, consumer responses to branding efforts and packaging), pricing, communication and retailing scenarios. The authors also incorporate insights into the complementarity of neurophysiological tools to traditional ones and situations in which these tools are useful for enhancing marketing theory. The authors finally shed light on the moral–ethical criticisms of this new branch of marketing.
Value
To the best of the authors’ knowledge, this research constitutes the first study in identifying the research opportunities that marketing researchers could take advantage from neuroimaging and physiological tools to inform marketing theory and practice.

Abstract
Purpose
The purpose of this paper is to answer the call for CSR communication research to develop and substantiate outcomes that may better explain CSR communication strategies and practices. The paper takes the research a step further, exploring the role of legitimacy in CSR communication research.
Design/methodology/approach
A literature collection methodology, combined with directed content analysis, was used to identify central themes in the literature.
Findings
The following categories of studies were identified: perception, impact and promotion studies; image and reputation studies; performance studies; and conceptual/rhetorical studies. Addressed from a legitimacy perspective, the study found that the most important types of legitimizing communicative practices articulated in the four types of studies were related to: seeking knowledge about stakeholders through perception, impact and promotion activities; monitoring and controlling the environment through image and reputation activities; creating stakeholder value through collaboration and engagement; and persuading and convincing stakeholders through rhetorics, CSR models and concepts. The study also found that practices and activities related to perceiving stakeholders’ expectations, needs and requirements are assumed to be most effective for corporations aiming at building or maintaining legitimacy.
Originality/value
The key contribution of the paper lies in exploring how corporate legitimacy is anticipated and extrapolated in the CSR communication literature, including which pinpointed CSR communication strategies and practices are assumed to be more effective than others in bridging stakeholders’ perceptions of corporations’ social and environmental actions. Until date, no reviews exist of the role of legitimacy in CSR communication research.

Abstract
Purpose
Traffic density is one of the most important parameters to consider in the traffic operation field. Owing to limited data sources, traditional methods cannot extract traffic density directly. In the vehicular ad hoc network (VANET) environment, the vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) interaction technologies create better conditions for collecting the whole time-space and refined traffic data, which provides a new approach to solving this problem.
Design/methodology/approach
On that basis, a real-time traffic density extraction method has been proposed, including lane density, segment density and network density. Meanwhile, using SUMO and OMNet++ as traffic simulator and network simulator, respectively, the Veins framework as middleware and the two-way coupling VANET simulation platform was constructed.
Findings
Based on the simulation platform, a simulated intersection in Shanghai was developed to investigate the adaptability of the model.
Originality/value
Most research studies use separate simulation methods, importing trace data obtained by using from the simulation software to the communication simulation software. In this paper, the tight coupling simulation method is applied. Using real-time data and history data, the research focuses on the establishment and validation of the traffic density extraction model.
