Purpose: A major part of knowledge management for knowledge-intensive firms such as professional service firms is the increasing focus on thought leadership. Despite being a well-known term, it is poorly defined and analysed in the academic and practitioner literature. The aim of this article is to answer three questions. First, what is thought leadership? Second, what tensions exist when seeking to create thought leadership in knowledge-based organisations? Third, what further research is needed about thought leadership? The authors call for cross-disciplinary and academic–practitioner approaches to understanding the field of thought leadership. Design/methodology/approach: The authors review the academic and practitioner literature on thought leadership to provide a rich oversight of how it is defined and can be understood by separating inputs, creation processes and outcomes. The authors also draw on qualitative data from 12 in-depth interviews with senior leaders of professional service firms. Findings: Through analysing and building on previous understandings of the concept, the authors redefine thought leadership as follows: "Knowledge from a trusted, eminent and authoritative source that is actionable and provides valuable solutions for stakeholders". The authors find and explore nine tensions that developing thought leadership creates and propose a framework for understanding how to engage with thought leadership at the industry/macro, organisational/meso and individual/micro levels. The authors propose a research agenda based on testing propositions derived from new theories to explain thought leadership, including leadership, reducing risk, signalling quality and managing social networks, as well as examining the suggested ways to resolve different tensions. Originality/value: To the best of the authors' knowledge, they are the first to separate out thought leadership from its inputs, creation processes and outcomes. The authors show new organisational paradoxes within thought leadership and show how they can play out at different levels of analysis when implementing a thought leadership strategy. This work on thought leadership is set in a relatively under-explored context for knowledge management researchers, namely, knowledge-intensive professional service firms. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to examine the impact of microblogging word of mouth (MWOM) through twitter on value co-destruction for Athens, as a tourism destination facing a sustained crisis. The study demonstrates the sentiment and sharing evolution of tweets, illustrating the value co-destruction of a tourism destination. Overall, the study expands understanding on the online footprints of MWOM in the field of tourism. Design/methodology/approach: It uses social media focused data mining and sentiment analysis, to analyze more than 90,000 tweets posted by top twitter influencers between 2013 and 2015. The methodology that the authors have adopted follows seven steps: first, identification of the top-5 twitter influencers who use the hashtag #Athens, based on their klout score; second, collection of tweets from the top-5 twitter influencers, for the period from January 2013 until June 2015; third, collection of the retweets metadata of the above tweets and of the corresponding retweeter accounts (i.e. user id, name, screen name), together with the frequency of retweeting per tweet; fourth, collection of user metadata (i.e. location and number of followers) from the retweeter accounts; fifth, influence computation of retweetwers using their klout score; sixth, tweets classification based on the klout score of their retweeters; and seventh, sentiment analysis of the collected tweets. Findings: The findings show the high potential of value co-destruction in virtual environments, through negative MWOM related to tourism destinations in crisis, and shared among highly influencing users, that disseminate negative stories through microblogging. The findings also reveal the existence of negativity bias that can reduce the risks of visiting a new destination facing a crisis and, at the same time, significantly destroy the destination's value. Originality/value: This is the first study to examine the impact of MWOM through twitter on a tourism destination facing a sustained crisis, such as Athens. This study uses social media focused data mining and sentiment analysis, to analyze more than 90,000 tweets posted by top twitter influencers between 2013 and 2015. The findings reveal the existence of negativity bias that can reduce the risks of visiting a new destination facing a crisis and, at the same time, significantly destroy the destination's value.

Purpose: The purpose of this paper is to analyze the moderating effects of the social influence of the blogger and the extent to which the reader has experience of that blogger, on loyalty toward the blogger, via two variables: blogger interactive practices (BIPs) and blogger credibility. Design/methodology/approach: A quantitative empirical study was undertaken to estimate the research model. Structural equations were employed. Findings: The results show that blogger social influence moderates the relationships between BIPs and intention to recommend the blogger and blogger credibility; and between credibility and intention (to recommend the blogger and to follow their suggestions). Meanwhile, the extent of the reader's experience of the blogger moderates the relationships between BIPs and intention. Practical implications: The present work offers criteria that may be of value to bloggers and firms in assessing the extent to which the blogger's activities are effective in terms of achieving reader loyalty. The proposed variables are measured objectively online, using the Klout Index of social influence and the extent of the reader's experience of the blogger (inferred from the number of bloggers followed by the reader). Originality/value: Blogs are considered a mechanism to manage information overload in social media, and they are recognized for their influence on the reader's decision-making process. The study contributes to the knowledge-base by proposing two moderating variables of loyalty-formation: blogger social influence and the extent of the reader's experience of the blogger.

Purpose: Misinformation can have lasting impacts in the management and control of a public emergency. The purpose of this paper is to demonstrate how misinformation flows and how user characteristics can shape such flows in the context of a violent riot in Singapore. Design/methodology/approach: The authors apply the two-step flow theory and discuss the mixed methods approach involving wrangling Twitter data and descriptive analysis to develop and analyse two corpuses of misinformation related to the riot. Findings: The findings are mostly consistent with the two-step flow theory, in that misinformation flows to the masses from opinion leaders (as indicated by higher measures such as online social influence and followers/following ratio). In the presence of misinformation, tweets opposing such misinformation may not always come from opinion leaders. Practical implications: The authors work furthers knowledge about how misinformation goes viral, which provides practical implications to help policymakers and scholars in understanding and managing the dynamics and pitfalls of misinformation during an emergency. Originality/value: This paper tackles the problem of misinformation in public emergencies using a mixed methods approach and contributes to ongoing theoretical work on managing online misinformation especially in public emergencies and crises.
