Ecologies of Boundaries: Modes of Boundary Work in Professional Proto‐Jurisdictions

Ecological approaches to professional work, authority, and regulation have seen a resurgence in the sociology of professions, as epitomized in the linked ecologies framework of Andrew Abbott. Alongside this resurgence comes a renewed attention to the way symbolic and material boundaries within and between professions, as well as between professional, university, and political institutions, come to be defined, negotiated, and changed as part of ongoing professional projects. Building on and comparing case studies set in Denmark into three emerging professional “proto‐jurisdictions”—of water‐related climate adaptation, lifestyle disease prevention, and innovation management—this article identifies three key modes of interprofessional boundary work important for such projects. In doing so, it grounds Abbott's meso‐level framework of linked ecologies in more situated accounts of workplace‐level boundary interaction, by reconnecting to a wider tradition of symbolic interactionist studies of professions.     

Governance,Accountability, and Organizational Development: Eldercare Unit Managers’ and Local Politicians’ Experiences of and Responses to State Supervision of Swedish Eldercare

This article explores how local politicians and care unit managers in Swedish eldercare experience and respond to state supervision (SSV). Twelve politicians and twelve managers in 15 previously inspected municipalities were interviewed about their experiences of and reactions to SSV in relation to their views of care quality and routines in eldercare practice. The findings indicate that local managers and political chairs perceived SSV in eldercare positively at a superficial level but were critical of and disappointed with specific aspects of it. In terms of (a) governance, chairs and managers said SSV strengthened implementation of national policies via local actors, but they were critical of SSV’s narrow focus on control and flaws in eldercare practice. With regard to (b) accountability, SSV was seen as limited to accountability for finances and systemic performance, and regarding (c) organizational development, SSV was seen as limited to improving routines and compliance with legislation, while local definitions of quality are broader than that. In general, local actors regarded SSV as improving administrative aspects and routines in practice but ignoring the relational content of eldercare quality.     

A Convolution Estimator for the Density of Nonlinear Regression Observations

Abstract. The problem of estimating an unknown density function has been widely studied. In this article, we present a convolution estimator for the density of the responses in a nonlinear heterogenous regression model. The rate of convergence for the mean square error of the convolution estimator is of order n ^?1 under certain regularity conditions. This is faster than the rate for the kernel density method. We derive explicit expressions for the asymptotic variance and the bias of the new estimator, and further a data‐driven bandwidth selector is proposed. We conduct simulation experiments to check the finite sample properties, and the convolution estimator performs substantially better than the kernel density estimator for well‐behaved noise densities.     

‘Blowing up the pylon’: the limitations to Lacanism in organization studies,seen from the perspective of Deleuze and Guattari

We critically engage with the Lacanian notions of fantasy and lack through an understanding of desire as ontologically productive. The introduction of the Lacanian psychoanalytic notions of fantasy and lack into organizational studies has helped to widen the understanding of the mechanism that makes employees desire the idealized images of identity provided by the organizations for which they work. Our claim is that Deleuze’s and Guattari’s conception of desire as productive contributes to the understanding of the role that desire plays in producing and organizing the social setting in which such fantasies and a sense of lack emerge in the first place. Furthermore, we argue that Deleuze and Guattari can help point to the inherent danger of Lacanism’s blunting its own analytical and critical potential when trying to understand such social settings.     

Service tasks of board of directors: A literature review and research agenda in an era of new governance practices

In their seminal review article on board of directors, Johnson, Daily, and Ellstrand (1996) distinguished between the control, service, and resource dependence tasks of the board and called for a stronger focus on board service tasks. Following this call, service tasks of boards have been subject to increased scholarly attention, with new theoretical perspectives and methods introduced. This paper aims at presenting the current state of research on board service tasks, departing from, and building on, the contribution of Johnson and colleagues. In doing so, we employ an Input-Process-Output-Context framework and craft an agenda for how future research could accommodate new governance practices and progress the field. Our review is relevant and timely as studies on the subject are gaining traction both in corporate governance and general management journals. Furthermore, our review on board service tasks proposes new alternative approaches to studying corporate governance which are especially appropriate in times in which a rethink of corporate governance frameworks and concepts is urgently needed.     

On the History of the Correction for Grouping, 1873–1922

The correction for grouping is a sum of two terms, the first depending on the length of the grouping interval, the second being a periodic function of the position. Thiele (1873) studied the second term, but missed the first. Sheppard (1898) studied the first term, but missed the second. Bruns (1906) derived the first term as the aperiodic term of a Fourier series and the second as the sum of the periodic terms. He found the correction to the coefficients of the Gram–Charlier series and proved that the second term is negligible for a grouped normal distribution with at least eight groups. Independently, Fisher (1922) used the same method to derive the correction to the moments. For the normal distribution with a grouping interval less than the standard deviation Fisher proved that the second term is negligible compared with the first and with the standard error of the first four moments. Moreover, he proved that the estimates of the mean and the standard deviation obtained by the method of moments for a grouped sample with Sheppard's corrections have nearly the same variances as the maximum likelihood estimates, thus providing a new and compelling reason for using Sheppard's corrections.     

The effect of MRP lot sizing on actual cumulative lead times in multi-level systems

This study investigates how different lot sizing techniques influence the cumulative lead time for multi-level production-inventory systems controlled by material requirements planning (MRP). Theoretical approaches, a numerical example, as well as simulation are used to analyse and illustrate the combined effect of lot sizing at different product structure levels. It is shown that lot-sizing requirements for more than a single period, such as fixed period requirements, period under quantity, Silver Meal algorithm, as well as economic order quantity will lead to longer actual cumulative lead times than would be expected, when taking the item lead times along the critical path through the product structure into account. Consequently, MRP will underestimate the cumulative lead time and will require a longer planning horizon. We show that the extension of the cumulative lead techniques covering the time is a lot-sizing related phenomenon and cannot be accounted for by, e.g. using safety lead time. Lot-sizing techniques with multi-period coverage will only occasionally provide the 'expected' cumulative lead time. We also show that average and maximum throughput times, as well as throughput time variability increases with increasing time-period coverage of lots.
