Consistency and identifiability

The paper explores by elementary methods the relation between the concepts of consistency and identifiability. It is shown quite simply that consistency implies identifiability but that the converse is not necessarily true.

Coalitional games with veto players: Consistency, monotonicity and Nash outcomes

Following Dagan et al. [Dagan, N., Volij, O., Serrano, R. (1997). A non-cooperative view on consistent bankruptcy rules, Games Econ. Behav. 18, 55–72], we construct an extensive form game for veto-balanced TU games in which a veto player is the proposer and the other players are responders. The set of Nash outcomes of this extensive form game is described, and compared to solutions of TU games such as the nucleolus, kernel and egalitarian core. We find necessary and sufficient conditions under which the nucleolus of the game is a Nash outcome.     

Editorial introduction: HRM and performance: confronting theory and reality

This editorial introduction has twin purposes. The first is to make a wide audience aware of the new Dutch HRM Network. The second is to introduce a set of papers which make a contribution to the connections between HR policies/strategies and organizational performance. These purposes are linked by the fact that the papers come from the inaugural conference of the Network that was held in the Rotterdam School of Economics at Erasmus University at the end of 1999.     

Sustainable supply chains: An introduction

Consideration is given to the convergence of supply chains and sustainability. In doing so, the focus on environmental management and operations is moved from local optimization of environmental factors to consideration of the entire supply chain during the production, consumption, customer service and post-disposal disposition of products. This is a critical and timely topic that captures increasing concerns over sustainability, whether driven by current legislation, public interest, or competitive opportunity. As such, sustainable development is a rich area for academic research that is still in its infancy and has the potential to affect future government policy, current production operations, and identify new business models. This paper provides a background to better understand current trends in this multidisciplinary field that intersect with operations management, and the research opportunities and challenges it presents.     

Procedures and Consistency Versus Flexibility and Commitment In Employee Relations: A Comment On Storey

Jon Clark, who is Professor of Industrial Relations at Southampton University, comments on one of the most important issues raised in John Storey's Developments in the Management of Human Resources: the contrast between the ‘procedure and consistency’ of the IR/ personnel tradition and the ‘business need, flexibility and commitment’ of the HRM tradition. In particular, he queries whether HRM can be successful without a firm basis in ‘procedure and consistency’.

Scales of measurements: An introduction and a selected bibliography

Stevens' (1946) distinctions among nominal, ordinal, interval and ratio measurements have had a marked influence on researchers of social, psychological and statistical sciences. This paper reviews those distinctions and includes some comments concerning the applicability of different statistical techniques to each scale. A detailed bibliography is also provided.On study leave from Department of Statistics, University of Karachi, Karachi-32, Pakistan.     

Multifactor productivity and its determinants: an empirical analysis for Mexican manufacturing

The aim of this paper is twofold. First, we estimate production functions for the Mexican manufacturing sector and for 14 comprehensive groups, allowing us to construct various measures of multifactor productivity. Second, we analyse some of the determinants of productivity growth. We find that, on the one hand, there is a positive relationship between market concentration and technology adoption; on the other hand, both technology adoption and human capital promote productivity, whilst market concentration exerts a negative influence on it. Our results suggest that, once controlling for the effect on technology adoption, more concentration impacts negatively productivity growth.     

Turnover propensity and its causes among Singapore nurses: an empirical study

Nurse turnover has been a serious challenge to the efficiency and effectiveness of any health-care delivery system. Various antecedents of turnover are examined in this study in attempt to identify the most critical causes of the problem. One hundred and eighty nurses from a large hospital in Singapore participated in the survey. The results show that a) stress strikes throughout different stages in turnover development; b) professional commitment is a significant cause of turnover cognition, but not turnover intention; and c) organizational commitment and supervision satisfaction are among the top predictors of turnover intention. These results deviated from the apprehension of many health administrators about the causes of the nursing turnover, thus provided clues as to how to mitigate the problem. And, as they were compatible with the results of studies on Canadian and American nurses, these results contributed to the empirical generalization process. The implication of the findings is discussed in the paper.
