Segnalazione bibliografica. American Political Science Review 01 August 2011 105: 631-641 Autore: Andrew Rehfeld Abstract In this reply to Jane Mansbridge's “Clarifying the Concept of Representation” in this issue (American Political Science Review 2011). I argue that our main disagreements are conceptual, and are traceable to the attempt to treat the concept of representation as a “single highly complex concept” as Hanna Pitkin once put it. Instead, I argue, it would be more useful to develop the various concepts that emphasize the underlying forms of representation. Against the view that empirical regularity should guide concept formation, I suggest that the failure to find...

Ward; Audrey Sacks American Journal of Political Science, Volume 55, Number 4, 1 October 2011 , pp. 991-1002(12) Abstract We present a visual method for assessing the predictive power of models with binary outcomes. This technique allows the analyst to evaluate model fit based upon the models' ability to consistently match high-probability predictions to actual occurrences of the event of interest, and low-probability predictions to nonoccurrences of the event of interest. Unlike existing methods for assessing predictive power for logit...

Segnalazione bibliografica. Acta Politica 46, 400-424 (October 2011) Autore: Simon Otjes Abstract The List Pim Fortuyn (LPF) is a key example of a family of new right-wing parties that, according to many observers, have had a strong effect on European party systems.

And second, has the LPF been able to create a new significant line of conflict in the legislature, as Kriesi...

Segnalazione bibliografica. American Political Science Review 01 August 2011 105: 552-566 Autori: Timothy Besley; Marta Reynal-Querol Abstract This paper uses a unique data set on over 1,400 world leaders between 1848 and 2004 to investigate differences in educational qualifications between leaders who are selected in democracies and autocracies. After including country and year fixed effects, we find that democracies are around 20% more likely to select highly educated leaders. This finding is robust to a wide range of specifications, choices of subsamples, controls, and ways of measuring education and democracy.
