This study seeks to examine the relationship between innovation and knowledge in family versus non-family businesses with regard to performance. Data from 430 small and medium-sized enterprises were analyzed through hierarchical regression analysis, and innovation was found to be a significant factor in both family and non-family samples. However, knowledge in family firms was also found to be significant with innovation. Implications for theory and practice are discussed that may provide possible competitive advantage for small family firms.
Purpose
Microblogging is an important channel used to disseminate online public opinion during an emergency. Analyzing the features and evolution mechanism of online public opinion during an emergency plays a significant role in crisis management.
Design/methodology/approach
This paper uses the event of Hurricane Irma and combines it with the life cycle of online public opinion evolution to understand the effect of different types of emotional (joy, anger, sadness, fear, disgust) microblogs (tweets) on information dissemination. The research was performed in the context of Hurricane Irma by using tweets associated with that event.
Findings
This paper demonstrates that negative emotional information has a greater communication effect, and further, the target audience that receives more exposure to negative emotional microblogs has a stronger tendency to retweet. Meanwhile, emotions expressed in tweets and the life cycle of public opinion evolution exert interactive effects on the retweeting behavior of the target audience.
Research limitations/implications
For future research, a professional dictionary and the context should be taken into consideration to make the modeling in the text more normative and analyzable.
Practical implications
This paper aims to reveal how the emotions of a tweet affect its virality in terms of diffusion volume in the context of an emergency event.
Social implications
The conclusion made in this paper can shed light on the real-time regulation and public opinion transmission, as well as for efficient intelligence service and emergency management.
Originality/value
In this study, Hurricane Irma is taken as an example to explore the factors influencing the information dissemination during emergencies on the social media environment. The relationship between the sentiment of a tweet and the life cycle of public opinion and its effect on tweet volume were investigated.
Competitive intelligence (CI) is the selection, collection, interpretation and distribution of publicly held information that is strategically important to a firm. A substantial amount of this public information is accessible via the World Wide Web. This paper describes some of the difficulties in using this information resource for CI purposes, some of the solutions to these difficulties, and areas in need of research if the Web is to be used in CI.
