Strategies for business model innovation: How firms reel in migrating value

This paper brings together firm-level research on business models and industry-level research on value migration to examine patterns of business model innovation. We draw on qualitative data from 14 cases and 68 interviews in the computer and telecommunications industries to demonstrate how business model innovation is sensitive to industry-wide forces of value migration. Based on our analysis we conclude that when value is rapidly migrating across industries and between firms, proactively substituting key elements of the primary business model provides a better fit with the new value landscape than launching secondary business models in parallel. We suggest four underlying mechanisms that link business model innovation, value migration and subsequent outcomes. Unpacking business model innovation allows us to discuss contingencies for the main business model strategies, specifically in terms of limitations to—and opportunities of—changing the primary business model and the practice of parallel business models.     

Authentic leadership and leaders' mental well-being: An experience sampling study

Research on authentic leadership has yielded important insights about its effects on subordinates. However, its consequences for the leaders themselves remain largely unexamined. This is problematic, as organizations require their leaders to provide guidance and leaders' mental well-being is a prerequisite for this. Drawing on the theories of ego-depletion and authentic leadership, we investigate the role of authentic leadership in predicting leaders' mental well-being. In an experience sampling study, we apply hierarchical linear modeling to analyze 396 observations from 44 executives. Our multilevel moderated mediation analyses reveal that authentic leadership reduces leaders' stress and increases their work engagement and that these effects are mediated by leader mental depletion. Moreover, we show that the indirect effects are contingent on the extent to which leaders interact with their subordinates: authentic leaders deplete less with increasing follower interaction, while inauthentic leaders deplete less with decreasing follower interaction.     

Changing Public Service Organizations: Current Perspectives and Future Prospects

As governments and public service organizations across the globe engage in strategies of institutional and organizational change, it is timely to examine current developments and a future research agenda for public governance and management. The paper commences with reflections on the state of the field, based on an analysis of papers published in the British Journal of Management over the last decade. While there was some variation apparent across the set, the ‘typical’ article was found to be influenced by the discipline of organizational behaviour, set within the health‐care sector, using case‐study methods within field‐based studies, and investigating shifts in roles and relationships and the management of change. It has also in the past been UK‐centric, though the journal editorial policy and our own article call for a stronger international and comparative focus in the future. The second section of the article summarizes the articles and themes contained in this collection of papers on public service organizations. The third section explores a possible research agenda for the future, arguing for the significance of public sector research for the understanding of management more generally, and for examining the interface between private and public organizations (an increasingly common phenomenon). We suggest the need to set public services research in policy and political contexts, and suggest this may reveal organizational processes of wide interest. We call for a wider set of disciplines to engage in public management research, and to engage in moving the agenda from the study of efficiency to effectiveness as defined by a variety of stakeholders. We address the issue of how far public management researchers should become directly engaged with the world of policy and suggest that whether researchers engage in Mode 1 or Mode 2 research, their work would benefit from a stronger theoretical base.     

Theoretical properties of tests for spatial clustering of count data

Testing for spatial clustering of count data is an important problem in spatial data analysis. Several procedures have been proposed to this end but despite their extensive use, studies of their fundamental theoretical properties are almost non‐existent. The authors suggest two conditions that any reasonable test for spatial clustering should satisfy. The latter are based on the notion that the null hypothesis should be rejected almost surely as the amount of spatial clustering tends to infinity. The authors show that the chisquared test and the Potthoff—Whittinghill V have both properties but that other classical tests do not.     

Recent trends in marital disruption

The post-1980 decline in the crude divorce rate must be interpreted in the context of the long-term trend and in terms of what we know about composition effects on crude measures-particularly given shifts in age at marriage and the age composition effects of the baby boom. Data from the June 1985 Current Population Survey permit more detailed, exposure-specific measurements as well as the use of separation as the event terminating marriage. Estimates from these data suggest a decline followed by a recovery. Taking into account well-known levels of underreporting, we find that recent rates imply that about two-thirds of all first marriages are likely to end in separation or divorce. We examine the persistence of major differences in marital stability and evaluate the comparative stability of first and second marriages.     

Conversation with Herbert S. Strean

Dr. Herbert Strean has been a most influential practitioner and educator in the advancement of clinical social work. Not only has he made an outstanding contribution to our professional literature, but has also been a major critic of our profession's movement away from its therapeutic obligation to clients. Since its inception, he has been on the editorial board of this journal and a regular contributor. After a distinguished career as a professor at Rutgers University Graduate School of Social Work he has retired to direct the New York Center for Psychoanalytic Training. We are fortunate to have the first interview with him after his retirement from Rutgers.
