Legislative Twitter Style: Electoral Vulnerability,Social Media,and Constituency-Building in Large Multimember Electoral Systems

How do legislators use social media to cultivate their constituencies in large multimember electoral districts? Colombia's Senate nationwide district offers a suitable case to examine how lawmakers, through their behaviour on Twitter, geographically target their audiences. We employ microblog user geolocation methods which infer locations using textual content in order to identify where Colombian senators' Twitter ‘home’ is. We find that senators' location targeting on Twitter largely mirrors the geographical distribution of their votes. Deviations from that pattern mostly stem from their vulnerability to intraparty competition and the nature of their parties' organisation.

Burundi: des identités ethnico-politiques forgées dans la violence

Taking the recent political situation as background, the author examines the rhetoric of political propaganda in Burundi. By considering several texts, both written (newspaper articles, politicians’ statements, political leaflets) and oral (speeches and radio declarations), of which long excerpts are reproduced, the author is able to demonstrate that all parties call for violence in Burundi, regardless of political side. The Other, whoever he may be, is systematically denied the right to exist; meanwhile, the exercise of violence appears as a means of delimiting the space belonging to each group. This in turn legitimates and generalizes daily use of violence.     

Behavioural Response to a Sudden Health Risk: Dengue and Educational Outcomes in Colombia

Epidemics tend to have a debilitating influence on the lives of directly afflicted families. However, the presence of an epidemic can also change the behaviour and outcomes of those not directly affected. This paper makes use of a short, sharp, unexpected epidemic to examine the behavioural response of the public to a sudden shift in the perceived risk to one’s health and mortality. Our analysis finds that unafflicted school students change their behaviour substantially, affecting important life outcomes. In particular, we find that between 1.9 and 4.7 fewer students, out of a typical cohort of 47 pupils, sit their school leaving examination for every additional 10 cases of severe Dengue per 10 000 inhabitants in a municipality. We rule out several possible mechanisms, leaving an increase in the salience of the disease’s risks as a plausible explanation for our findings.
