Users frequently target rival brands through direct criticism or indirect customer insults, yet the impact of such attacks on brand advocacy remains unexplored. The purpose of this study is to classify online attacks into brand-targeted attacks and consumer-targeted attacks and further investigate their differential impacts on brand advocacy and the underlying mechanism and a boundary condition of those impacts.

Three experimental studies using different types of brands (electronics, universities and sports footwear) are conducted to examine the effects of brand-related attack targets on brand advocacy.

This research shows that consumer-targeted attacks trigger higher brand advocacy through increasing perceived identity threat than brand-targeted attacks. Moreover, the effect of consumer-targeted attacks (versus brand-targeted attacks) on brand advocacy is mediated by perceived identity threat and mitigated when consumers’ identification with the attacked brand is strong.

The study’s findings yield practical applications for marketers and brand managers, assisting them in understanding consumers’ reactions to brand attacks. This study serves as a reference for firms to consider leveraging the association between brand identification and brand-related attack targets and uniting with loyal brand fans to manage online brand conflicts.

The present study extends prior literature on customer-brand relationships in the context of online attacks. Through investigating the impacts of brand-targeted and consumer-targeted attacks on brand advocacy, this research offers theoretical insights into consumers’ responses to online attacks with different targets.

The authors contribute to the literature on leadership by investigating how characteristics of principal investigators (PIs) affect innovation performance, and how collaborative and non-collaborative projects moderate this relationship within the context of inter-organisational research projects.

The authors analysed panel data from the National Science and Technology Information Service on 171 research projects within a biomedical and regenerative medicines programme overseen by the Korea Health Industry Development Institute. The authors used a hierarchical regression model, based on the ordinary least squares method, to examine the relationship between PI characteristics and performance, considering both quantity and quality.

The results show that the characteristics of PIs have diverse effects on the quantity and quality of innovation performance. Gender diversity within PIs negatively affects the quality of innovation performance, while the capacity of PIs positively influences it. Moreover, the degree of PI’s engagement is positively associated with the quantity of innovation performance but does not have a significant relationship with the quality of performance. In terms of moderating effects, collaborative projects with multiple leaders seem less reliant on PI capacity than non-collaborative projects led by a single leader, in terms of innovation performance.

The results contribute significantly to the literature on innovation management by examining the role of leadership in collaborative environments to enhance innovation performance, addressing the need for empirical evidence in this area. Analyses of PI characteristics in government R&D management can lead to improved team performance, more efficient processes and effective resource allocation, ultimately fostering innovation.

In the past decade, financial austerity has brought significant pressure upon emergency services in the UK. For the British Government, one approach to alleviate this pressure was to increase collaborative efforts in core functions (e.g. information systems and technology) between multiple organisations. Despite the consensus that collaborations are key in addressing complex problems, the majority fail or become discontinued. This research explores the development of collaborative information infrastructures between one Police Force and two Fire and Rescue Services in the UK, with a specific focus on how the difference in culture, identities and rules and norms, can work in a collaborative emergency service environment.

This study investigated an example of successful development of a collaborative information infrastructure within the context of public safety and, specifically, the technology-based structures that underpin information management. A case study approach was taken, combining semi-structured interviews, document analysis and site visits. The study used activity theory as a theoretical and analytical framework.

The research revealed that creating a shared identity is not essential in emergency services collaboration, and organisations may maintain their separate identity, given they address other elements of the activity system (e.g. leadership, motivated subjects). However, pursuing this strategy will create multiple tensions throughout the collaboration process.

The study contributes to the information systems literature concerning inter-organisational collaborations in the public sector providing a novel view to the implications of maintaining separate identities, and the significance of misalignment between interacting activity systems.
