American Journal of Political Science 56(1), 17-33 (January 2012) Abstract Evidence that political attitudes and behavior are in part biologically and even genetically instantiated is much discussed in political science of late. Yet the classic twin design, a primary source of evidence on this matter, has been criticized for being biased toward finding genetic influence. In this article, we employ a new data source to test empirically the alternative, exclusively environmental, explanations for ideological similarities between twins. We find little support for these explanations and...

Segnalazione bibliografica. British Journal of Political Science (2011), 41: 259-285 Autori: John Bartle, Sebastian Dellepiane-Avellaneda, James Stimson Abstract The political ‘centre’ is often discussed in debates about public policy and analyses of party strategies and election outcomes. Yet, to date, there has been little effort to estimate the political centre outside the United States. This article outlines a method of estimating the political centre using public opinion data collected for the period between 1950 and 2005. It is demonstrated that it is possible to measure the centre in Britain, that it moves over time, that it shifts in response to government activity...

This article focuses on the electoral strategies of state-wide parties (SWPs) with regard to centre–periphery issues in regional elections. It applies Meguid’s Position–Salience–Ownership (PSO) theory to regional electoral competition in Spain and the United Kingdom. We anticipate that SWPs will seek to vary their strategies, especially in regional elections where they face fierce competition from regionalist parties. We also expect their strategies to be influenced by the SWPs' strategy in state-wide elections. The analysis reveals that the key assumptions of the PSO stack up quite well when applied to regional elections. It also reveals the influence of the multi-layered institutional context in which SWPs compete: at the regional level, said parties do not necessarily adopt the most logical strategy according to the PSO theory if this runs counter to the prevailing SWP strategy at the state-wide level.

Autrice: Yanna Krupnikov American Journal of Political Science, Volume 55, Number 4, 1 October 2011 , pp. 797-813(17) Abstract Do negative campaign advertisements affect voter turnout? Existing literature on this topic has produced conflicting empirical results. Some scholars show that negativity is demobilizing. Others show that negativity is mobilizing. Still others show that negativity has no effect on turnout. Relying on the psychology of decision making, this research argues and shows that this empirical stalemate is due to the fact that existing work ignores a crucial...
