The Differential Effects of Transformational Leadership on Multiple Identifications at Work: A Meta‐analytic Model

Employees’ identifications are a valuable asset for modern organizations, and identification research has stressed the necessity to distinguish identifications according to their focus (i.e. organizational, team, or leader identification). Interestingly, transformational leadership (TFL) has been proposed to unfold its effects by transforming followers’ identifications and could thus be a powerful way to actively manage identification. However, it remains unclear whether TFL affects identifications with different foci similarly or whether it predominantly influences a specific focus. To resolve this puzzle, the authors conducted a meta‐analysis (k = 73; N = 20,543) and found that TFL (and each TFL sub‐dimension) is more strongly associated with leader identification than with organizational identification or team identification. By presenting a comprehensive model of TFL's effects on identifications, we show that leader identification mediates the relationships between TFL and collective identifications (i.e. organizational identification or team identification), illustrating that relational identification plays a crucial role in subsequently shaping collective identifications. Implications for research and practice are discussed.     

Antecedents and effects of individual ambidexterity – A cross-level investigation of exploration and exploitation activities at the employee level

For long-term success, companies need to adapt to technological and environmental change. Organizational ambidexterity, which balances the exploration of new opportunities with the exploitation of existing capabilities, is increasingly viewed as a promising approach to tackle this challenge. However, despite the important role of individuals for firms' ambidexterity and performance, evidence on how exploration of new opportunities and exploitation of existing capabilities are triggered at an individual level and on their subsequent effects on overall performance is still lacking. Accordingly, the present research shifts the focus from organizational ambidexterity to individual ambidexterity. Based on data from 415 employees, the results of structural equation modeling show that both organizational architecture and organizational context can be used to induce individual ambidexterity. Furthermore, positive performance effects of individual ambidexterity across different organizational levels, namely the team and department levels, are confirmed.     

How does a component from a supplier with high reputation for product innovation improve the perception of a final offering? A process perspective

An excellent reputation for product innovation (RPI) is an intangible asset for any company and promises a sustainable competitive advantage. This study empirically analyzes the spillover effects of a high component supplier's RPI to the offering of the original equipment manufacturer (OEM). The results show that there are positive effects to be gained from the innovativeness of a component supplier, which increases the perceived performance of the final offering containing the supplier's product. In addition, the study demonstrates that such a strategic partnership between a component supplier and an OEM has the potential to influence the purchase intention of the final consumer in a positive manner, thereby creating value for both parties. Contributions are made to a better understanding of strategic options for such a partnership and to an on-going discussion on RPI and the importance of intangible attributes in innovation management.     

Bartlett's Test Applied to Variance Component Models

Exact methods for testing equality between variance components obtained from several cases of the same type of balanced orthogonal design are discussed. In particular, methods for successively testing equality of a number of components using Bartlett's tests are outlined for univariate and multivariate responses. Two clinical trial examples of repeated‐measures data are presented.     

How Do Individuals Apply Risk Information When Choosing Among Health Care Interventions?

A sample of 3,201 Danes was subjected to personal interviews in which they were asked to state their preferences for risk-reducing health care interventions based on information on absolute risk reduction (ARR) and relative risk reduction (RRR). The aim of the study was to measure the relative weighting of different types of risk information under various circumstances. The effect of presenting questions, and of explicitly formulating RRR, was analyzed. A preference for increases in RRR was demonstrated. There was a stronger inclination to choose the intervention that offered the highest RRR if RRR was explicitly stated. Individuals with more than 10 years of schooling also demonstrated a preference for increased ARR, but only when facing individually framed choices. In a social choice context, preferences for RRR remained intact, but the magnitude of ARR had no impact on choices. Results imply that social framing may induce a propensity to prefer interventions that target high-risk populations. Those respondents who had received < or = 10 years of schooling demonstrated preferences for RRR but not ARR, and no impact of social framing was observed.
