Exploring relationships between audio features and emotion in music
2009
In this paper, we present an analysis of the associations between emotion categories and audio features automatically extracted from raw audio data. This work is based on 110 excerpts from film soundtracks evaluated by 116 listeners. This data is annotated with 5 basic emotions (fear, anger, happiness, sadness, tenderness) on a 7 points scale. Exploiting state-of-the-art Music Information Retrieval (MIR) techniques, we extract audio features of different kind: timbral, rhythmic and tonal. Among others we also compute estimations of dissonance, mode, onset rate and loudness. We study statistical relations between audio descriptors and emotion categories confirming results from psychological …
First impression misleads emotion recognition
2019
Recognition of others' emotions is a key life ability that guides one's own choices and behavior, and it hinges on the recognition of others' facial cues. Independent studies indicate that facial appearance-based evaluations affect social behavior, but little is known about how facial appearance-based trustworthiness evaluations influence the recognition of specific emotions. We tested the hypothesis that first impressions based on facial appearance affect the recognition of basic emotions. A total of 150 participants completed a dynamic emotion recognition task. In a within-subjects design, the participants viewed videos of individuals with trustworthy-looking, neutral, or untrustworthy-lo…
Influencia de la inteligencia emocional y el apoyo social sobre el bienestar subjetivo: un estudio transcultural España-Ecuador
2021
Marco teórico: la inteligencia emocional es una de las variables psicológicas más estudiadas en la actualidad, así como el apoyo social, que puede actuar como protector de la salud y el bienestar psico-lógico. El objetivo principal del trabajo es estudiar la relación entre la inteligencia emocional y el apoyo social percibido con la felicidad subjetiva y la satisfacción vital en universitarios de dos culturas y con-textos diferentes: España y Ecuador. Método: 760 estudiantes universitarios, incluyendo 379 españoles (83.1% mujeres) y 381 ecua-torianos (76.6% mujeres), completaron las escalas Trait Meta Mood Scale, Multidimensional Scale of Perceived Social Support, Satisfaction With Life Sca…
Negative and Positive Bias for Emotional Faces: Evidence from the Attention and Working Memory Paradigms
2021
Visual attention and visual working memory (VWM) are two major cognitive functions in humans, and they have much in common. A growing body of research has investigated the effect of emotional information on visual attention and VWM. Interestingly, contradictory findings have supported both a negative bias and a positive bias toward emotional faces (e.g., angry faces or happy faces) in the attention and VWM fields. We found that the classical paradigms—that is, the visual search paradigm in attention and the change detection paradigm in VWM—are considerably similar. The settings of these paradigms could therefore be responsible for the contradictory results. In this paper, we compare previou…
Income, Sex, Pills and Relationships: An Empirical Study for Argentina
2016
We use 28 years of Argentina’s life satisfaction (LS) and happiness (HA) data to test the Easterlin Paradox and find out the actual determinants of happiness. Argentineans are happier now than in 1984, and the City of Buenos Aires leads in present rankings of happiness in Argentina. In the cross-section analysis, LS correlates with the satisfaction about the economic situation of households, but the satisfaction with family and time spent with loved ones have a higher explanatory power. When it comes to HA, high social class members do not always buy a ticket, but low class makes people sadder. Nontraditional variables – pills for mental stress and sex – were also studied.
High levels of the molecular chaperone Mdg1/ERdj4 reflect the activation state of endothelial cells
2003
Mdg1/ERdj4, a mammalian chaperone that belongs to the HSP40 protein family, has been reported to be located in the endoplasmic reticulum (ER), is induced by ER stress, and protects ER stressed cells from apoptosis. Here we show that under normal physiological conditions, Mdg1/ERdj4 is expressed at various levels in the vasculature due to different activation states of the endothelium. To elucidate the stimuli that induce ER stress and thus upregulate Mdg1/ERdj4, we investigated the effect of several endothelium specific stressors on its expression. Mdg1/ERdj4 mRNA is induced by activated macrophages, by nitric oxide (NO) and heat shock, and during terminal cell differentiation, whereas shea…
Understanding of tactile pictures in visual impaired children
2015
The present PhD aims at understanding how Visual Impaired (VI) children process the tactile pictures that illustrate the tactile books specially designed for them. Our work is organized around two main axes of analysis. The first axis concentrates on the child who explores the tactile images, while the second axis focuses on the impact that the properties of these images can have on children’s haptic processing. Our researches included children presenting various degrees of visual impairment but without any associated disorders (in particular, without any cognitive delay), distinguishing early blind children from children with low vision. We also compared their performance with those of sig…
Numerical Assessment of Heating Energy Demand for Office Buildings in Italy
2016
Abstract Buildings energy consumption depends on several parameters, such as climate, envelope typologies, occupant behavior, intended use, etc.; assessment of the energy performance of a building requires substantial input data describing constructions, environmental contexts, thermo-physical properties, geometry, control strategies and several other parameters influencing the thermal balance. In the last years, several numerical approaches dedicated to building simulation have been tested developing specialized software. On the other hand, simplified building models permit the evaluation of indoor conditions and heating/cooling loads with a good level of accuracy and without excessive com…
Springback evaluation in fully 3-D sheet metal forming processes
1997
Abstract In the modern manufacturing industries the knowledge and proper control of the sheet metal springback after forming is a fundamental aspect in the achievement of near net shape stamped parts. In this paper an effective springback prediction in some fully three-dimensional stamping processes is carried out. Such a prediction is based on a combined approach in which an explicit finite element code has been employed to simulate the forming phase while a traditional implicit procedure has been used to analyse the springback phase. The results obtained have been compared with a set of experimental tests and an excellent correlation between the predicted and experimental data has been fo…
Numerical Analysis of Piezoelectric Active Repair in the Presence of Frictional Contact Conditions
2013
The increasing development of smart materials, such as piezoelectric and shape memory alloys, has opened new opportunities for improving repair techniques. Particularly, active repairs, based on the converse piezoelectric effect, can increase the life of a structure by reducing the crack opening. A deep characterization of the electromechanical behavior of delaminated composite structures, actively repaired by piezoelectric patches, can be achieved by considering the adhesive layer between the host structure and the repair and by taking into account the frictional contact between the crack surfaces. In this paper, Boundary Element (BE) analyses performed on delaminated composite structures …
