Impliciete en expliciete leeftijdsdifferentiatie in pensioencontracten
No full textDit design paper van Roel Mehlkopf (Tilburg University), Jan Bonenkamp, Casper van Ewijk, Harry ter Rele en Ed Westerhout (allen Centraal Planbureau) gaat in op twee vormen van leeftijdsdifferentiatie in pensioencontracten: impliciete en expliciete leeftijdsdifferentiatie. Zij laten hierin zien dat in huidige pensioencontracten sprake is van impliciete leeftijdsdifferentiatie: de aanspraken van jongere deelnemers hebben een risicovoller profiel dan die van oudere deelnemers. Maar expliciete leeftijdsdifferentiatie heeft een aantal voordelen menen de auteurs. Zij gaan in dit paper in op de potentiële voordelen van een overgang van huidige, uniforme contracten met impliciete leeftijdsdifferentiatie naar nieuwe contracten met expliciete leeftijdsdifferentiatie

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Will ageing lead to a higher real exchange rate for the Netherlands?
Get PDFLong-term projections for the Netherlands indicate that demand for nontradables ââ¬â e.g. health care services ââ¬â will increase relative to supply due to population ageing. If this leads to higher future real exchanges rates this will erode the return of the savings currently made to prepare for ageing. This paper explores the magnitude of potential price effects using a modified version of the ‘two country, four commodity framework’ developed by Obstfeld and Rogoff (2005) to explore the exchange rate effects of the balance of payments reversal in the US. When these price effects are substantial, this may have serious consequences for policies to enhance national saving in the Netherlands.
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
