El cumplimiento del Acuerdo de Paz de El Salvador
El Salvador es hoy, a veintiún años de la firma de Acuerdo dePaz de Chapultepec, una sociedad plural y un país en paz, regido por instituciones democráticas que cumplen con las funciones que les atribuye su Constitución. Esa es la medida del éxito del proceso de negociación iniciado con los buenos oficios de la Organización de Naciones Unidas el 15 de septiembre de 1989 en Ciudad de México y concluido el 16 de Enero de 1992, también en Ciudad de México, con la firma del Acuerdo de Paz mencionado
Extracting Risk Neutral Densities For Weather Derivatives Pricing Using The Maximum Entropy Method
In this study we propose the use of the maximum entropy method to extract the risk
neutral probabilities directly from the weather market prices. The proposed methodology is computationally fast, model free, non-parametric and can overcome the data sparsity problem that governs the weather market. We infer consistent risk neutral probabilities along with their densities from the market price of temperature options. The risk neutral probabilities inferred from a smaller subset of the data are consistent in the sense that they reproduce the other prices and can be used to value accurately all other possible derivatives in the market sharing the same underlying asset. We examine two sources of the out-of-sample valuation error. First, we use different sets of possible physical state probabilities that correspond to different levels of expertise of the trader. Then, we apply our methodology under three scenarios where the available information in the market is based on historical data, meteorological forecasts or both. Our results indicate that different levels of expertise can affect the accuracy of the valuation. When there is a mix of information, non-coherent sets of prices are observed in the market
Imagen país de Colombia desde la perspectiva extranjera
Colombia is a country with a negative historical positioning in international markets. Despite efforts by governments and influencers to improve its image, the perception of foreigners remains polarized, being associated with coffee and drug trafficking. This article is the result of a qualitative research conducted on foreign visitors from eight countries in the Americas with the largest number of visitors to Colombia in 2013: The United States, Venezuela, Ecuador, Argentina, Peru, Brazil, Mexico and Chile. The study found that the image of Colombia is not one-dimensional, but multidimensional. It identifies five dimensions that influence country image: knowledge of the country, the industrial orientation, visitor attitudes, perceptions of prospects and preferences and finally interests associated with its image.Colombia es un país con un posicionamiento histórico negativo en mercados internacionales.

Marble melancholy: using crossmodal correspondences of shapes, materials, and music to predict music-induced emotions
Introduction: Music is known to elicit strong emotions in listeners, and, if primed appropriately, can give rise to specific and observable crossmodal correspondences. This study aimed to assess two primary objectives: (1) identifying crossmodal correspondences emerging from music-induced emotions, and (2) examining the predictability of music-induced emotions based on the association of music with visual shapes and materials.
Methods: To achieve this, 176 participants were asked to associate visual shapes and materials with the emotion classes of the Geneva Music-Induced Affect Checklist scale (GEMIAC) elicited by a set of musical excerpts in an online experiment.
Results: Our findings reveal that music-induced emotions and their underlying core affect (i.e., valence and arousal) can be accurately predicted by the joint information of musical excerpt and features of visual shapes and materials associated with these music-induced emotions. Interestingly, valence and arousal induced by music have higher predictability than discrete GEMIAC emotions.
Discussion: These results demonstrate the relevance of crossmodal correspondences in studying music-induced emotions. The potential applications of these findings in the fields of sensory interactions design, multisensory experiences and art, as well as digital and sensory marketing are briefly discussed.Peer Reviewe
