The Politics of Minister Retention in Presidential Systems: Technocrats, Partisans, and Government Approval

This article examines the impact of presidential approval and individual minister profiles on minister turnover. It claims that, in order to prioritize sustainable policy performance and cabinet loyalty, government chiefs protect and remove technocrats, partisans, and outsider ministers conditional on government approval. The study offers an operational definition of minister profiles that relies on fuzzy-set measures of technical expertise and political affiliation, and tests the hypotheses using survival analysis with an original dataset for the Argentine case (1983–2011). The findings show that popular presidents are likely to protect experts more than partisan ministers, but not outsiders.

Variety of Media Systems in Third-Wave Democracies

The number of comparative studies in the field of political communication increased considerably after Daniel Hallin and Paolo Mancini's publication of comparing Media systems. In this book, four dimensions are used to distinguish between the media environments in western countries around the year 2000: press market development, parallelism between parties and media outlets, state intervention in the realm of media, and levels of journalist professionalization. The authors conclude that in western Europe and North America three types of media systems coexisted: a polarized pluralist model (in southern Europe), a democratic corporatist model (in scandinavia and some western European countries), and a liberal model (Canada, USA, Ireland, and the UK). Within this framework, both Portugal and Spain are described as polarized pluralist media systems, given their weak press markets and low patterns of journalistic professionalization, as well as strong state intervention in the realm of media and parallelism between media outlets and political parties.
