Taking Stock of Temporary Organizational Forms: A Systematic Review and Research Agenda

This paper brings together the research on temporary organizational forms. Despite a recent surge in publications on this topic, there have been few attempts to integrate knowledge on what we know of such temporary forms of organization. In order to correct this, an integrative framework is proposed around four central themes: time, team, task and context. Within each of these themes, the paper offers an overview of the literature, the gaps in what we know, and what future directions might be taken by scholars hoping to contribute to this important and rapidly growing field.     

Die deutschen Gewerkschaften: Ein Review der aktuellen Forschungsliteratur

Unions, particularly in Germany, are the subject matter of intense public debates as well as discussions in academic research, which corroborate the former. The last systematically conducted analysis of the status quo in academic research was done in spring 2001. In view of the rather dramatic symptoms of the crisis German unions are facing, it is time to incorporate the latest results of scientific research. This paper addresses this task against the background of a systematic literature review. Three application areas are distilled out of a total of 79 pieces of research that are considered relevant and intensively discussed: (1) the membership in German unions, (2) the unions in the German system of industrial relations and (3) the reformation of the German unions. The detected symptoms of the unions' crisis are impressively documented and explained by the studies. However, shortcomings regarding the respective research questions and the development of recommendations for future courses of action for the unions can also be identified.     

Asymptotic robustness of least median of squares for autoregressions with additive outliers

This paper considers the robustness properties in the time series context of the least median of squares (LMS) estimator. The influence function of the LMS estimator is derived under additive outlier contamination. This influence function is redescending and bounded for fixed values of the AR parameters. The gross-error sensitivity, however, is an unbounded function of the AR parameters. In order to asses the global robustness behavior of the LMS estimator, we consider several notions of breakdown. The breakdown points of the LMS estimator depend on the value of the underlying AR parameter. Generally, the breakdown point is below one half for high values of the AR parameter. The bias curves of the LMS estimator reveal, however, that the magnitude of outliers has to be considerable in order to cause breakdown.

A Corporate Culture Pattern to Manage Business Ethics

Within the general frame of proposals for an adequate management of business ethics, this paper is based on the vision of corporate culture as a pattern to achieve such purpose. If we consider ethics as a specific value of corporate culture, we may resort to the mechanism of cultural change and implementation in order to manage ethics. Despite the difficulties it entails in terms of time and money investment, this procedure is one of the safest ways to reach ethical values which are known, shared and then practiced by all the members of a corporation, whatever the category. From this central standpoint, and basing ourselves on our own proposal for the management of culture, we shall describe which specific steps must be taken in order to achieve a set of ethical values which are both realistic and furthermore shared by all collaborators of an organization. This revised version was published online in July 2006 with corrections to the Cover Date.     

Institutional Shifts In Inter-Municipal Service Delivery

Comparative research on inter-municipal cooperation in eight European countries shows that there is a great variety of institutional arrangements for cooperation across the different countries. Also, these arrangements tend to change over time in terms of the scope of cooperation among partners, their composition and the degree of organizational integration. This article describes and analyzes the variety of and shifts in institutional arrangements for a specific class of inter-municipal cooperation arrangements: those that are set up to provide for the joint delivery of public services. It is argued that specific arrangements are typically the outcomes of interaction between national institutional contexts, environmental factors and local preferences.     

The minimal overlap rule revisited

This paper provides an analysis of the Minimal Overlap Rule, a solution for bankruptcy problems introduced by O’Neill (1982). We point out that this rule can be understood as a composition of Ibn Ezra’s proposal and the recommendation given by the Constrained Equal Loss Rule. Following an interpretation of bankruptcy problems in terms of TU games, we show that the Minimal Overlap Value is the unique solution for bankruptcy games which satisfies Anonymity and Core Transition Responsiveness.     

Influence diagnostics in the capital asset pricing model under elliptical distributions

In this paper we consider the Capital Asset Pricing Model under Elliptical (symmetric) Distributions. This class of distributions, which contains the normal distribution, t, contaminated normal and power exponential, among others, offers a more flexible framework for modelling asset prices or returns. In order to analyze the sensibility to possible outliers and/or atypical returns of the maximum likelihood estimators, the local influence method was implemented. The results are illustrated by using a set of shares from companies who trade in the Chilean Stock Market. Our main conclusion is that symmetric distributions having heavier tails than those of the normal distribution, especially the t distribution with small degrees of freedom, show a better fit and allow the reduction of the influence of atypical returns in the maximum likelihood estimators.
