Less than Expected? How Media Cover Demonstration Turnout

Demonstration turnout is a crucial political resource for social movements. In this article, we investigate how mass media cover demonstration size. We develop a typology of turnout coverage and scrutinize the factors that drive turnout coverage. In addition, we test whether media coverage underestimates, reflects, or exaggerates "guesstimates" by organizers and police forces. Together, these a...

Erratum: SGDQN is Less Careful than Expected

The SGD-QN algorithm described in (Bordes et al., 2009) contains a subtle flaw that prevents it from reaching its design goals. Yet the flawed SGD-QN algorithm has worked well enough to be a winner of the first Pascal Large Scale Learning Challenge (Sonnenburg et al., 2008). This document clarifies the situation, proposes a corrected algorithm, and evaluates its performance.

Expected Benefits of Voting and Voter Turnout

This empirical study seeks to identify key aggregate-level economic and non-economic determinants of the expected benefits from voting and hence aggregate voter turnout.

Is the impact of childhood influenza vaccination less than expected: a transmission modelling study

BACKGROUND To reduce the burden of severe influenza, most industrialized countries target specific risk-groups with influenza vaccines, e.g. the elderly or individuals with comorbidities. Since children are the main spreaders, some countries have recently implemented childhood vaccination programs to reduce overall virus transmission and thereby influenza disease in the whole population. The in...
