Sur une méthode d'interpolation

Abstract

I. Dans ce journal, MM. Palmqvist et Poukka¹ ont montré comment la solution de certains problèmes d'interpolation peut être améliorée par application du procédé général de M. Lindelöf. Il est possible de retrouver ces résultats par une méthode très élementaire. C'est ce point de vue, que nous développel'ons brievement.     

Product Design: Preference for Rounded versus Angular Design Elements

Two experiments tested whether a general relative preference for objects with rounded rather than angular form (Bar & Neta, 2006, 2007) can be applied in the context of the design of consumer products. Images of product packaging—a chocolate product (Experiment 1) and water and bleach bottles (Experiment 2)—were manipulated with regard to the shape of both contour and graphics. There was a preference for rounded designs that extended to self‐report purchase likelihood—with additive effects of contour and graphics shape that could not be accounted for by design typicality or perceived ease of use.     

The influence of guided preparation on the long-term performance of new ventures

This article further develops a theory of guided preparation and new venture performance and tests its fundamental relationships on a sample of 159 new ventures that received outsider assistance 5–9 years earlier and had been in business for 3–8 years. The results suggest that the long-term growth of the ventures since start-up is significantly related to guided preparation. However, a curvilinear model rather, than a linear model, was found to best capture the relationships of interest. This suggests that there are diminishing marginal returns associated with guided preparation and that too much may even have a negative influence on performance.     

Financing medical specialist services in The Netherlands: Welfare implications of imperfect agency

Since 1995 the financing scheme for medical specialist services in the Netherlands has moved from a fee-for-service scheme to a capitation scheme. This paper analyzes the economic and welfare effects of this policy change. The paper adopts a numerical model that integrates demand and supply considerations and that recognizes the potential roles of moral hazard and supplier-induced demand. The paper finds that the shift in financing regime has been welfare-reducing. The policy change induced medical specialists to lower the supply of the health services which was already lower than optimal before the policy reform.

Exchange or Covenant? The Nature of the Member-Union Relationship

Drawing on a study of members of the U.K. National Union of Teachers, this article considers the extent to which economic exchange, social exchange, and covenantal considerations underpin union members' willingness to continue membership and to participate actively in their union through union citizenship behaviors (UCB). Findings suggest that the more activist forms of UCB were motivated primarily by a perceived covenantal relationship with the union. In contrast, exchange, particularly social exchange, motivations played more of a role in motivating less demanding "rank and file" UCB and intent to quit the union. Union instrumentality appeared to be a necessary but insufficient condition for union viability, having an indirect effect on UCB and intent to quit the union and also moderating the effects of pro-union attitudes. Implications for union strategy are considered.
