The roles of leader emotion management and team conflict for team members' personal initiative: A multilevel perspective

Employees' personal initiative (i.e., their active and future-oriented engagement at work) is of high relevance to organizations that strive for innovation and competitiveness. To better understand its drivers and diminishers, the present study refers to Affective Events Theory and examines the impact of leader emotion management, team conflict, and affective well-being on personal initiative. Data from 300 members of 59 work teams in Germany were gathered from multiple sources at three points in time over the course of 2 weeks. Multilevel analyses indicated that leader emotion management positively affected team members' personal initiative and that this effect was mediated by team members' affective well-being. Data also revealed a contrasting negative indirect effect of task conflict within the team on team members' personal initiative via team members' affective well-being. The study's results suggest that the improvement of leaders' emotion management as well as the establishment of work conditions and experiences that foster affective well-being should be seriously considered by organizations wishing to facilitate personal initiative in team settings.     

Objective age-of-acquisition (AoA) norms for a set of 230 object names in French: Relationships with psycholinguistic variables,the English data from Morrison et al. (1997), and naming latencies

Picture naming speed is strongly influenced by the age of acquisition (AoA) of words. Most studies of AoA have relied on adults' AoA ratings. However, objective AoA has been found to be a stronger determinant of picture naming latencies. Whereas objective AoA norms for words have been collected for some language communities, no objective AoA measures for words were previously available in French. The study provides objective AoA norms for a set of 230 object names following the procedures used by Morrison, Chappell, and Ellis (1997) to collect objective AoA measures in English. The relationships between objective AoA measures, rated AoA, other variables used in psycholinguistic experiments (name agreement, image agreement, conceptual familiarity, etc.), the English data collected by Morrison et al., and naming latencies are analysed and discussed. In addition, reanalyses of data on picture naming latencies (Bonin, Chalard, Méot, & Fayol, 2002) with the use of objective AoA norms are provided. Stepwise multiple analyses show that objective AoA is a stronger determinant of (spoken and written) naming latencies than rated AoA, whereas objective word frequency is not a reliable independent determinant and does not interact reliably with AoA in any of the analyses.     

Bringing actors together around large-scale water systems: Participatory modeling and other innovations

Conclusion The five areas of innovation found in the three case studies have brought actors together in new ways around water management strategies. We paid special attention to the role of participatory modeling, because it has been able to generate new policy options. For such complex and often deadlocked water management issues, new options are at a premium. The cases demonstrate that participatory modeling efforts are a key part of successfully addressing these major water management issues faced in the U.S. as well as elsewhere. Recent publications include Ecology, Engineering and Management: Reconciling Ecosystem Rehabilitation and Service Reliability (with Emery Roe; Oxford: Oxford University Press). Current research interest include the reliability of critical infrastructures (such as electricity, water, telecommunications and the internet) and the development of methods to recast the intractable policy issues. Since 1999, he has been a Visiting Scholar at the University of California, Berkeley and Mills College, Oakland. where he teaches and directs research in the application of economic theory and systems analysis methods to the solution of environmental and regional water resources problems. He has authored numerous articles and book chapters, served on various committees of the National Research Council of the National Academy of Sciences, and was a U.S. member of an advisory committee for the International Institute for Applied Systems Analysis (IIASA) in Laxenburg, Austria. Emery Roe has published widely on science, technology and environmental controversies, including the debates over large technical systems, sustainable development, and ecosystem management. His books include Narrative Policy Analysis (Duke University Press, 1994), Taking Complexity Seriously: Policy Analysis, Triangulation and Sustainable Development (Kluwer, 1998), Except-Africa: Remaking Development, Rethinking Power (Transaction, 1999), and Ecology, Engineering and Management: Reconciling Ecosystem Rehabilitation and Service Reliability (with Michel van Eeten; Oxford: Oxford University Press).
