What makes music emotionally significant? Exploring the underlying mechanisms
2013
A common approach to study emotional reactions to music is to attempt to obtain direct links between musical surface features such as tempo and a listener’s response. However, such an analysis ultimately fails to explain why emotions are aroused in the listener. In this article, we propose an alternative approach, which seeks to explain musical emotions in terms of a set of underlying mechanisms that are activated by different types of information in musical events. We illustrate this approach by reporting a listening experiment, which manipulated a piece of music to activate four mechanisms: brain stem reflex; emotional contagion; episodic memory; and musical expectancy. The musical excer…

In this diary study with N = 348 employees, we examine whether the contagion effect of workplace incivility transfers beyond one work day that is whether the experience of workplace incivility is r...
Modeling Political Corruption in Spain
2021
Political corruption is a universal phenomenon. Even though it is a cross-country reality, its level of intensity and the manner of its effect vary worldwide. In Spain, the demonstrated political corruption cases that have been echoed by the media in recent years for their economic, judicial and social significance are merely the tip of the iceberg as regards a problem hidden by many interested parties, plus the shortage of the means to fight against it. This study models and quantifies the population at risk of committing political corruption in Spain by identifying and quantifying the drivers that explain political corruption. Having quantified the problem, the model allows changes to be …
From Continuous to Discontinuous Transitions in Social Diffusion
2018
Models of social diffusion reflect processes of how new products, ideas or behaviors are adopted in a population. These models typically lead to a continuous or a discontinuous phase transition of the number of adopters as a function of a control parameter. We explore a simple model of social adoption where the agents can be in two states, either adopters or non-adopters, and can switch between these two states interacting with other agents through a network. The probability of an agent to switch from non-adopter to adopter depends on the number of adopters in her network neighborhood, the adoption threshold $T$ and the adoption coefficient $a$, two parameters defining a Hill function. In c…
Interbrain emotional connection during music performances is driven by physical proximity and individual traits.
2021
How musical emotions and the pleasure derived from music, regardless of the musical valence, can be shared between individuals is a fascinating question, and investigating it can shed light on the function of musical reward. We carried out our investigations in a natural setting during an international competition for orchestra conductors. Participants (n = 15) used a dedicated smartphone app to report their subjective emotional experiences in real time while we recorded their cerebral activity using electroencephalography and their electrodermal activity. The overall behavioral real-time behavioral ratings suggest a possible social influence on the reported and felt pleasure. The physicall…
Propagation of Bankruptcy Risk over Scale-Free Economic Networks.
2022
The propagation of bankruptcy-induced shocks across domestic and global economies is sometimes very dramatic; this phenomenon can be modelled as a dynamical process in economic networks. Economic networks are usually scale-free, and scale-free networks are known to be vulnerable with respect to targeted attacks, i.e., attacks directed towards the biggest nodes of the network. Here we address the following question: to what extent does the scale-free nature of economic networks and the vulnerability of the biggest nodes affect the propagation of economic shocks? We model the dynamics of bankruptcies as the propagation of financial contagion across the banking sector over a scale-free network…
Transmisión entre mercados bursátiles y crisis financiera : el caso de España
2020
El trabajo analiza si la interrelación entre el mercado bursátil español y las bolsas de Estados Unidos, Reino Unido, Alemania y Francia se ha visto afectada y cómo por la reciente crisis financiera. Para ello, se estima un modelo VAR- GARCH bivariante, durante el período enero de 2000 a junio de 2012. Del modelo estimado se obtiene una medida del grado de integración de los mercados, el coeficiente de correlación condicional, y de éste se concluye que la crisis subprime produjo un efecto contagio entre los mercados bursátiles. Asimismo, la evidencia empírica permite concluir que en el período poscrisis ha aumentado la interrelación de la bolsa española con la francesa, reduciéndose la inte…
The Role of Anticipatory Emotions and their Contagiousness in an IS Project
2020
The previous research has shown increasing interest in understanding anticipatory emotions and their contagion, which can happen in dyads or groups as well as in other settings in organizations. The role of anticipatory emotions and their behavioral effects remain unexplored in IS projects. To address the research gap, we conducted a qualitative and longitudinal case study in order to understand what arethe role and consequences of the anticipatory emotions in IS project work, and how their contagiousness emerges over time. Adopting a model of group emotional contagion as a theoretical lens provided us with an opportunity to explain the relationship between anticipatory emotions and emotion…
Emotion recognition, emotional awareness and cognitive bias in individuals with bulimia nervosa
2008
Difficulties recognizing emotion have been reported for eating disordered individuals in relation to perception of emotions in others and emotional self-awareness. It remains unclear whether this is a perceptual or cognitive-affective problem. Clarification is sought and the question of a cognitive bias is addressed when interpreting facially expressed emotions. Twenty participants with bulimia nervosa (BN) and 20 normal controls (NC) were assessed for ability to recognize emotional and neutral expressions. Emotional self-awareness was also assessed. Significant differences were found for emotional self-awareness. For emotional faces, only a poorer recognition of the emotion, surprise, for …
Spillovers through banking centers: a panel data analysis of bank flows
2003
Abstract This paper presents evidence that spillovers through bank lending contributed to the transmission of currency crises during the recent episodes of financial instability in emerging markets. The innovation of the paper is that it looks beyond aggregated measures of contagion into the structure of bank flows, disaggregating by banking centers. The main findings are that spillovers caused by banks’ exposures to a crisis country help predict flows in third countries after the Mexican and Asian crises, but not after the Russian crisis. In the latter, there is evidence of a generalized outflow from emerging markets. The importance of spillovers through banking centers suggests that count…
