Proportionality and the power of unequal parties

In this paper we introduce the concept of an overall power function that is meant to combine two sources of a party's power in a parliament. The first source is based on the possibilities for the party to be part of a majority coalition and it is typically modeled using a cooperative simple game. The second source takes into account parties' asymmetries outside the cooperative game and it is displayed by a vector of exogenously given weights. We adopt a normative point of view and provide an axiomatic characterization of a specific overall power function, in which the weights enter in a proportional fashion.     

Who should be the respondent? Comparing predictive powers between managers' and employees' responses in measuring high-performance work systems practices

This study first examines the association between the effectiveness of high-performance work systems (HPWS) and two types of firm performance (the financial performance and productivity of a firm) in Korea and then compares the relative predictive power between employee responses and manager responses. The results indicate that the effectiveness of HPWS has a statistically significant positive effect on firm performance and that employee perception of the effectiveness of human resource (HR) practices explains more variance in the financial performance and productivity of firms than does managers' corresponding perception. This study highlights the importance of a firm's employees as a source of HR information.     

Innovation and HRM: Absences and politics

This article analyses the role of HRM practices in the implementation of an innovative cross-functional approach to new product development (concurrent engineering, CE) in Eurotech Industries. Contrary to CE methodology stipulations, and despite supportive conditions, HRM received scant attention in the implementation process. Organizational power and politics were clearly involved in this situation, and this article explores how their play created such HRM ‘absences’. The article builds on a four-dimensional view of power in order to provide a deeper understanding of the embedded, interdependent and political nature of HRM practice and innovation.     

The ‘Human’ Touch

Abstract

This article critically discusses the almost mythical conception of voluntary and ‘grass-roots’ organizations as problem solvers in current welfare policy – a myth, which over the last twenty years has become increasingly dominant in social policy programmes in advanced liberal welfare states. In particular, the article examines the assumption that voluntary and local organizations are permeated by a different rationality that enables human beings to act as ‘real humans’ rather than as professionals and clients – a rationality which is, however, permanently at risk of being contaminated by bureaucratic influence. It is demonstrated that among the conditions of possibility for this discourse are explanatory models and concepts in modern organizational theory and in voluntary sector studies. The article argues that the conceptualizations of power, rationality and social change dominant in these studies are unsatisfactory. Instead, it applies a Foucauldian approach to the domain of drug addiction treatment, analysing a social work ‘regime’ that transgresses the traditional boundaries between state and voluntary sector.
