The paper aims to investigate the importance of leadership – distributed leadership (DL) – for the relationship between organizational learning (OL) and business sustainability (BS).

Extensive literature research was carried out to investigate the relationship among leadership, OL and BS. Two theoretical frameworks of the relationship among DL, OL and BS were formulated and tested on the basis of the empirical studies conducted in 694 Polish and Danish companies. The moderated multiple regression and mediation analysis were used.

In-depth, critical literature analysis has shown that the theoretical foundation of the relationship between leadership and BS is limited and not empirically verified. However, the empirical study has revealed a positive, statistically significant effect of DL on both OL and BS and the mediating role of OL on the relationship between DL and BS (a partial and complimentary mediation).

It would be valuable to simultaneously consider other leadership types (beyond DL) in terms of their impact on OL and BS. Additionally, due to the nature of BS challenges and the specificity of DL, other factors influencing BS should be included for a more profound understanding of the relationships under investigation. Finally, additional contextual factors need to be taken into account.

To the best of the authors’ knowledge, the paper is one of the first studies that present the relationship between OL and BS with reference to factors influencing BS, i.e. leadership. The value of the paper is the development of two alternative models of the relationship among DL, OL and BS and their verification through large-scale empirical cross-country research. Furthermore, the results obtained in the course of the research open up new research directions with respect to the development of the concept of sustainable leadership and deepen the knowledge of the relationship between leadership types and OL.

There are two main objectives in this study. First, we aim to develop a set of constructs for health task management support (HTMS) features to evaluate which health-related tasks are supported by mobile health application (mHealth app) functions. Second, drawing on innovation resistance theory (IRT), we examine the impacts of the newly developed HTMS dimensions on perceived usefulness, alongside other barrier factors contributing to technology anxiety.

Using a mixed-method research design, this research seeks to develop new measurement scales that reflect how mHealth apps support older adults’ health-related needs based on interviews. Subsequently, data were collected from older adults and exploratory factor analysis was used to confirm the validity of the new scales. Partial least squares structural equation modeling (PLS-SEM) was used to analyze survey data from 602 older adults.

The PLS-SEM results indicated that medical management task support, dietary task support, and exercise task support were positively associated with perceived usefulness, while perceived complexity and dispositional resistance to change were identified as antecedents of technology anxiety. Perceived usefulness and technology anxiety were found to positively and negatively influence adoption intention, respectively.

This study enriches the information systems literature by developing a multidimensional construct that delineates how older adults’ health-related needs can be supported by features of mHealth apps. Drawing on IRT, we complement the existing literature on resistance to innovation by systematically examining the impact of five types of barriers on technology anxiety.

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.
