Inducing Rules of Ensemble Music Performance : A Machine Learning Approach
2013
Previous research in expressive music performance has described how solo musicians intuitively shape each note in relation to local/global score contexts. However, expression in ensemble performances, where each individual voice is played simultaneously with other voices, has been little explored. We present an exploratory study in which the performance of a string quartet is recorded and analysed by a computer. We use contact microphones to acquire four audio signals from which a set of audio descriptors is extracted individually for each musician. Moreover, we use motion capture to extract bowing descriptors (bow velocity/force) from each of the four performers. The gathered multimodal da…
Do large‐scale associations in birds imply biotic interactions or environmental filtering?
2023
Aim There has been a wide interest in the effect of biotic interactions on species' occurrences and abundances at large spatial scales, coupled with a vast development of the statistical methods to study them. Still, evidence for whether the effects of within-trophic-level biotic interactions (e.g. competition and heterospecific attraction) are discernible beyond local scales remains inconsistent. Here, we present a novel hypothesis-testing framework based on joint dynamic species distribution models and functional trait similarity to dissect between environmental filtering and biotic interactions. Location France and Finland. Taxon Birds. Methods We estimated species-to-species association…
Characterization of the mutualistic endosymbiosis between intracellular bacteria and mealybugs (Hemiptera: Pseudococcidae)
2015
Simbiosis, del griego sym “con” y biosis “vivir”, hace referencia a la asociación estable entre individuos de dos o más especies (simbiontes) que muestran interdependencia a cualquier nivel biológico. La ubicuidad de las asociaciones simbióticas en las ramas principales del árbol de la vida evidencia la relevancia global de éstas en la evolución de la vida. Las asociaciones más estudiadas son aquellas que se establecen entre procariotas y eucariotas que, habitualmente, suponen la ampliación de las capacidades metabólicas de los últimos. En este sentido, la simbiosis con bacterias intracelulares se considera un factor clave en el éxito adaptativo de los insectos. En función de su relevancia …
Discounting delayed monetary rewards and decision making in behavioral addictions - A comparison between patients with gambling disorder and internet…
2019
Abstract Behavior addictions, such as Gambling Disorder and Internet Gaming Disorder, have been demonstrated to have severe negative impact. Heightened impulsivity, deficits in decision making, and cognitive biases in the preference of immediate rewards have been shown to be crucial aspects in addictive disorders. While for Gambling Disorder (GD), dysfunctional decision making has been documented before, data for Internet Gaming Disorder (IGD) are still underrepresented. In order to allow for a direct comparison of both disorders, we assessed different measures of impulsivity (trait, impulsive choice, and decision making) in a clinical sample. N = 31 patients meeting criteria for GD and n =…
Addiction-Like Mobile Phone Behavior – Validation and Association With Problem Gambling
2018
Mobile phone use and its potential addiction has become a point of interest within the research community. The aim of the study was to translate and validate the Test of Mobile Dependence (TMD), and to investigate if there are any associations between mobile phone use and problem gambling. This was a cross-sectional study on a Swedish general population. A questionnaire consisting of a translated version of the TMD, three problem gambling questions (NODS-CLiP) together with two questions concerning previous addiction treatment was published online. Exploratory factor analysis based on polychoric correlations was performed on the TMD. Independent samples T-tests, Mann-Whitney test, logistic …
Desire and its preternse: Analysis of Intersubjective relations in Frank Capra's It happened one night
2019
The following paper analyzes the plot of the 1934 film It Happened One Night, by Frank Capra, an authentic emblem within the film genre of romantic comedy. In it, the protagonists manage to overcome the obstacles that are offered in their way thanks to the pretense of a relationship, the marital one, which finally will end up becoming effective. Recalling a famous Lacanian sentence, according to which human beings “pretend to pretend”, the plot devised by Capra will be analyzed in order to go over the steps that sequence such pretenses. These give order to a process of maturity in which the characters will become what they represent, evidencing the sexual nature of the desire that had impel…
Stimuli-responsive bile acid-based metallogels forming in aqueous media
2015
Abstract The synthesis and gelation properties of a picolinic acid conjugated bile acid derivative in the presence of metal salts along with the stimuli-responsiveness of the systems are reported. The gels are formed in the presence of Cu 2+ ions in the solvent systems composed of 30–50% of organic solvent (MeOH, acetonitrile, or acetone) in water. The gels respond to various stimuli: they can be formed upon sonication or shaking, and their gel–sol transformation can be triggered by a variety of chemical species. NMR, MS, and SEM techniques are exploited in order to gain a deeper insight on the self-assembled systems.
Mujer y juego online. Propuesta de tratamiento de un caso de adicción a videobingo
2019
Desde la legalización del juego online en España el trastorno de juego se ha incrementado notablemente, ya que ha aumentado la disponibilidad y accesibilidad de un tipo de juego que es, de por sí, más adictivo que el tradicional. Aunque las tasas de prevalencia son superiores en hombres que en mujeres, ellas no son ajenas a este problema, que también suele concurrir con otros problemas de índole emocional. El trabajo que presentamos es un estudio de caso de una mujer procedente de los servicios de salud mental, que padecía, además de adicción al juego, una importante sintomatología clínica. Se describe el protocolo de tratamiento de adicción al juego online desarrollado en la Unidad de Inve…
P-110 - Gaming addiction - disturbed impulse control in internet addicts and pathological gamblers
2012
Internet Addiction (IA) is proposed to be added as a research diagnosis to the upcoming DSM-V while Pathological Gambling (PG) is proposed to be subsumed under the new section “Addiction and related disorders” as first behavioral addiction. The outpatient clinic for behavioral addiction of the clinic for psychosomatic medicine in Mainz offers counseling and treatment to patients suffering from IA and PG. Deficits in impulse control are suggested to be a key factor to addiction. Studies in PG have shown deficits in the ability to control impulses, for example in decision making, resisting temptation or behavioral inhibition. For Internet addiction previous research on impulse control is spar…
Good decision-making is associated with an adaptive cardiovascular response to social competitive stress.
2018
Competition elicits different psychological and cardiovascular responses depending on a person's skills. Decision-making has been considered a distal factor that influences competition, but there are no studies analyzing this relationship. Our objective was to analyze whether decision-making affects the response to competition. Specifically, we aimed to test whether good performers on a decision-making test, the Iowa Gambling Task (IGT), showed an adaptive cardiovascular response to competition. In all, 116 participants (44 women) performed the IGT and were classified into Good or Poor decision-makers. Subsequently, they were exposed to a stress task in two different conditions: a face-to-f…
