Wind energy, discourse, and indigenous social movements: the case of the APPJ in Oaxaca, Mexico

El desarrollo de los proyectos eólicos en los últimos años en el Istmo de Tehuantepec, Oaxaca, han impactado en las formas socioculturales de las comunidades indígenas zapotecas de la región. Como respuesta a estos proyectos eólicos han surgido movimientos sociales indígenas zapotecas que se oponen a las empresas privadas que se han visto beneficiadas por la política energética impulsadas por el Estado mexicano. Con base en la literatura sobre la teoría crítica del discurso y los movimientos sociales, analizamos el discurso de resistencia del movimiento social indígena zapoteca de la Asamblea Popular del Pueblo Juchiteco (APPJ) del municipio de Juchitán de Zaragoza, por ser un caso paradigmático de la resistencia a la política pública eólica en el Istmo de Tehuantepec, Oaxaca

Discovering HIV related information by means of association rules and machine learning

Acquired immunodeficiency syndrome (AIDS) is still one of the main health problems worldwide. It is therefore essential to keep making progress in improving the prognosis and quality of life of affected patients. One way to advance along this pathway is to uncover connections between other disorders associated with HIV/AIDS-so that they can be anticipated and possibly mitigated. We propose to achieve this by using Association Rules (ARs). They allow us to represent the dependencies between a number of diseases and other specific diseases. However, classical techniques systematically generate every AR meeting some minimal conditions on data frequency, hence generating a vast amount of uninteresting ARs, which need to be filtered out. The lack of manually annotated ARs has favored unsupervised filtering, even though they produce limited results. In this paper, we propose a semi-supervised system, able to identify relevant ARs among HIV-related diseases with a minimal amount of annotated training data. Our system has been able to extract a good number of relationships between HIV-related diseases that have been previously detected in the literature but are scattered and are often little known. Furthermore, a number of plausible new relationships have shown up which deserve further investigation by qualified medical experts
