Breaking the silence ceiling: how gender violence became into a social problem in Spain through media and politics

This research presents the explanatory model of the process of reconstruction of the ʺsocial problemʺ of Intimate Partner Violence (I.P.V) in Spain during last five years, with special attention to the role of media in this process. Using a content analysis of the three more diffused general newspapers, a content analysis of the minutes of the Parliament, and the statistics of the police reports and murders, from January of 1997 to December of 2001, it observes the relationship between the evolution of the incidence of Intimate Partner Violence (I.P.V) (measured by the number of deaths and the number of police reports) and the evolution of stories about this topic in press. It also studies the interconnection of the two previous variables with the political answer to the problem (measured by the interventions on the I.P.V. in the Senate and in the Congress). Data shows that, even though police reports have increased due to the contribution of politics and media, I.P.V murders keep on growing up.

Redes sociales en el entorno radiofónico: el uso de Twitter como fuente periodística en la Cadena SER

La incorporación de Twitter al ámbito de la comunicación ha supuesto una serie de cambios en el entorno periodístico que afectan no sólo a la distribución de las noticias, sino también a la identificación de fuentes, tendencias y noticias de alcance. El objetivo de esta investigación es determinar la estrategia de utilización periodística de Twitter como fuente informativa por parte de la Cadena SER. La metodología empleada es el análisis de contenido del perfil de Twitter de los cuatro programas informativos más representativos de la emisora durante los meses de julio a diciembre de 2012. Los resultados apuntan la prevalencia de esta plataforma como mecanismo de interconexión con el sistema mediático, frente a su posible uso como espacio en el que identificar e incorporar a su audiencia como fuente potencial.

Granger causality and systemic risk

Building on the concept of Granger causality in risk in Hong et al. (2009), and focusing on an international sample of large-capitalization banks, we test for predictability in comovements in the left tails of returns of individual banks and the global system. The main results show that large individual shocks (defined as balance-sheet contractions exceeding the 1% VaR level) are a strong predictor of subsequent shocks in the global system. This evidence is particularly strong for US banks with large desks of proprietary trading. Similarly, we document strong evidence of financial vulnerabilities (exposures) to systemic shocks in US subprime creditors.
