Measurement Error and Incentive Pay

Abstract. We will analyse the optimal incentive scheme when the risk‐neutral principal contracts with many risk‐averse agents. Each agent produces an individual contribution which jointly form a total output. Agents’ efforts are unobservable and the principal cannot observe individual outputs without an error. Neither the observed individual output of an agent nor the observed total output of the whole team are then sufficient statistics for the actual individual output in the sense of Blackwell. We show that the mixed contract of the pure piece‐rate contract and of the pure team contract then dominates the pure contracts from the principal's point of view.     

Narratives as Sources of Stability and Change in Organizations: Approaches and Directions for Future Research

Although narrative analysis has made significant advances in organization and management studies, scholars have not yet unleashed its full potential. This review provides an understanding of key issues in organizational narrative analysis with a focus on the role of narratives in organizational stability and change. We start by elaborating on the characteristics of organizational narratives to provide a conceptual framework for organizational narrative analysis. We elaborate on three key approaches to narrative analysis on stability and change: realist, interpretative, and poststructuralist. We then review several topic areas where narrative analysis has so far offered the most promise: organizational change, identity, strategy, entrepreneurship, and personal change. Finally, we identify important issues that warrant attention in future research, both theoretically and methodologically.     

Gender and National Identity Constructions in the Cross‐Border Merger Context

In this article we explore ways in which vertical gender inequality is accomplished in discourse in the context of a recent chain of cross‐border mergers and acquisitions that resulted in the formation of a multinational Nordic company. We analyse social interactions of ‘doing’ gender in interviews with male senior executives from Denmark, Finland and Sweden. We argue that their explanations for the absence of women in the top echelons of the company serve to distance vertical gender inequality. The main contribution of the article is an analysis of how national identities are discursively (re)constructed in such distancing. New insights are offered to studying gender in multinationals with a cross‐cultural team of researchers. Our study sheds light on how gender intersects with nationality in shaping the multinational organization and the identities of male executives in globalizing business.     

How Issues Become (Re)constructed in the Media: Discursive Practices in the AstraZeneca Merger

In this article, we put forward a novel way of exploring difference and contradiction in merging organizations. We examine how the media (re)constructs meanings in a major cross-border merger. Based on an analysis of press coverage, we attempt to specify and illustrate how particular issues are (re)constructed in media texts through interpretations of 'winning' and 'losing'. We also show how specific discourses are drawn on in this (re)construction. In the merger studied, discourse based on economic and financial rationale dominated the media coverage. Discourse promoting nationalistic sentiments, however, provided an alternative discursive frame to the dominant rationalistic discourse. We argue that the two basic discourses are enacted in three analytically distinct discursive practices in the media: factualizing, rationalizing and emotionalizing. We suggest that the ability of different actors such as top managers to make use of different discursive strategies and resources in promoting their 'versions of reality' in the media (or public discussion) is a crucial avenue for research in this area.

Environmental and crown related factors affecting street tree transpiration in Helsinki,Finland

We investigated the drivers of street tree transpiration in boreal conditions, in order to better understand tree water use in the context of urban tree planning and stormwater management. Two streets built in Helsinki in 2002, hemiboreal zone that had been planted either with Tilia?×?vulgaris or Alnus glutinosa f. pyramidalis were used as the study sites. Tree water use was measured from sap flow over the 2008–2011 period by the heat dissipation method. Penman-Monteith based evapotranspiration models of increasing complexity were tested against the tree water use measurements to assess the role of environmental and tree related factors in tree transpiration. Alnus and Tilia respectively used 1.1 and 0.8 l of water per m² of leaf area per day under ample water conditions, but the annual variation was high. The Penman-Monteith evapotranspiration estimate and soil water status changes explained over 80 % of the variation in tree transpiration when the model was parameterized annually. The addition of tree crown surface area in the model improved its accuracy and diminished variation between years and sites. Using single parameterization over all four years instead of annually varying one did not produce reliable estimates of tree transpiration. Tree transpiration, scaled to different canopy cover percentages, implied that the columnar Alnus trees could transpire as much as all annual rainfall at or less than 50 % canopy cover.     

Making Sense of a Transnational Merger: Media Texts and the (Re)construction of Power Relations

In this study of symbolic power relations in a transnational merger, we suggest that the popular media can provide a significant arena for (re)constructing national identities and power in this kind of dramatic industrial restructuring, and are an under-utilized source of empirical data in research studies. Focusing on the press coverage of a recent Swedish-Finnish merger, we specify and illustrate a particular feature of discursive (re)construction of asymmetric power relations; superior (Swedish) and inferior (Finnish) national identities, which, we argue, are embedded in the history of colonization and domination between the two nations. The findings of the present study lead us to suggest that a lens taken from post-colonial theory is particularly useful in understanding the wider symbolic power implications of international industrial restructuring.     

Associations of Physical Activity and Sedentary Behavior With Adolescent Academic Achievement

The Northern Finland Birth Cohort 1986 (N = 8,061) was used to investigated the joint associations of physical activity and sedentary behavior with academic achievement. Logistic regression analysis was used to evaluate how classes formed by latent class analysis (LCA) according to overall physical activity, sports club membership, viewing TV, using a computer, reading books and magazines, other sedentary activities, and sleep were associated with grade‐point average. When adjusted for gender, self‐rated health, and mother's education, physically active adolescents and generally active adolescents were about twice as likely to have high grade‐point average compared with sedentary TV viewers.
