Emotional intelligence and hot and cool cognitive control ability

Emotional intelligence (EI) is the ability to perceive, use, understand, and regulate emotions. The EI construct has been organized following three main approaches: performance-based ability model, a self-report mixed model, and a self-report ability model. EI appears to be beneficial to the performance of “hot” (i.e., emotionally laden) cognitive tasks when using performance-based ability models but not when using self-report EI models. The aim of the present study is to analyze the relationship between the three models of EI and cognitive control ability during the performance of hot and “cool” (i.e., non-emotionally laden) “go/no-go” tasks. 187 undergraduate students participated in the experimental design. They completed the three EI tests of interest as well as go/no-go tasks; the stimuli used for the hot and cool cognitive task were faces and geometric figures, respectively. Results show that individuals with higher EI, measured through the performance-based ability test, perform better on a hot cognitive control task. Specifically, we provide evidence for negative associations between the “managing” branch of EI measured through the performance-based ability test of EI and the cognitive control index of the hot go/no-go task; when using the self-report EI instruments, no consistent findings were achieved. The study found no such results with the cool task. Findings in terms of the validity and different implications of the different EI models are discussed.Universidad de Málaga.

The effects of the quality of social relationships and emotion regulation ability on the happiness of introvert individuals

Previous research has shown that extraverts are happier than introverts and, although happy introverts exist, it is unclear under what conditions they can achieve happiness. The aim of the present study is to analyze the quality of social relationships and emotion regulation ability as a possible factor for happiness in introvert individuals. 1006 adults (42% males) completed measures of extraversion, neuroticism, quality of social relationships, emotion regulation ability and happiness. Results shows that introverts have significantly lower happiness, quality of life, quality of social relationship and emotion regulation ability scores than extraverts. Besides, those individuals with high quality social relationships or high emotion regulation ability were happier. Introverts were happier when they had high scores for quality of social relationships and emotion regulation ability, however the effect size was small. These results suggest that emotion regulation and social relationships are important to understand the relationships between introversion and happiness.Universidad de Málaga.

Strategies for dealing with new technological and economic situation of Spanish advertising industry

El sector publicitario está viviendo grandes cambios que afectan a prácticamente todos los ámbitos de actividad y a todos los sujetos implicados. Con esta investigación pretendemos conocer la influencia que la crisis económica y la evolución tecnológica está teniendo en estas transformaciones y en las decisiones estratégicas que se ponen en marcha en el sector. Utilizando como herramienta metodológica la encuesta, se entrevista a más de 60 profesionales y académicos expertos en publicidad y en comunicaciones de marketing. De las respuestas de los encuestados podemos concluir que si bien la influencia de la crisis y de la tecnología es notable, no lo es con la misma intensidad en todas las variables analizadas.El mismo texto del resumen pero en inglés (o idioma alternativo) y en cursiva. Advertising industry is undergoing major changes that affect every area of activity, and all individual involved. With this research, we want to know the influence that the financial crisis and technological change is having on these transformations. Using the survey as a methodological tool, we interviewed more than 60 professional and academic experts in advertising and marketing communications. From the answers of the respondents, we can conclude that although the influence of the crisis and technology is remarkable, it is not with the same intensity in all variables analysed

Error estimation in multitemporal InSAR deformation time series, with application to Lanzarote, Canary Islands

Interferometric Synthetic Aperture Radar (InSAR) is a reliable technique for measuring crustal deformation. However, despite its long application in geophysical problems, its error estimation has been largely overlooked. Currently, the largest problem with InSAR is still the atmospheric propagation errors, which is why multitemporal interferometric techniques have been successfully developed using a series of interferograms. However, none of the standard multitemporal interferometric techniques, namely PS or SB (Persistent Scatterers and Small Baselines, respectively) provide an estimate of their precision. Here, we present a method to compute reliable estimates of the precision of the deformation time series. We implement it for the SB multitemporal interferometric technique (a favorable technique for natural terrains, the most usual target of geophysical applications). We describe the method that uses a properly weighted scheme that allows us to compute estimates for all interferogram pixels, enhanced by a Montecarlo resampling technique that properly propagates the interferogram errors (variance-covariances) into the unknown parameters (estimated errors for the displacements). We apply the multitemporal error estimation method to Lanzarote Island (Canary Islands), where no active magmatic activity has been reported in the last decades. We detect deformation around Timanfaya volcano (lengthening of line-of-sight ∼ subsidence), where the last eruption in 1730–1736 occurred. Deformation closely follows the surface temperature anomalies indicating that magma crystallization (cooling and contraction) of the 300-year shallow magmatic body under Timanfaya volcano is still ongoing.Peer reviewe

The relationship between the three models of emotional intelligence and psychopathy: a systematic review

Psychopaths are usually characterized as having numerous troubles with social and emotional facets in their daily. In addition, these individuals generate a series of harmful situations to society, such as violence and crime. Due to this, it is very important to find those variables that can reduce these behaviors. In this regard, Emotional Intelligence (EI) or the ability to perceive, use, understand and regulate emotions is a potentially useful variable. EI has been categorized according to three main approaches: performance-based ability, self-report ability and self-report mixed models. Several studies have analyzed the relationship between EI and psychopathy, however inconsistent results have been found. These inconsistencies may be due to the EI model employed to measure it. The objective of our study is to systematically review the previous literature about the relationship between the three models of EI and psychopathy, both in the clinical and total population.Scopus and Medline were searched for finding relevant articles. 29 eligible studies were identified. The results were divided according to the EI model and the population used.The results for both the total and clinical population differ according to the measure of EI employed. Specifically, through performance-based ability models, the majority of studies find a negative relationship between EI and psychopathy, and when EI is measured using self-reports, the results are inconsistent. In conclusion, the results suggest that higher EI abilities measured through performance-based ability models - but not through self-reports - are related to lower psychopathy deficits. Limitations and clinical implications are discussed.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Non-Lipschitz differentiable functions on slit domains

It is proved the existence of large algebraic structures –including large vector subspaces or infinitely generated free algebras– inside the family of non-Lipschitz differentiable real functions with bounded gradient defined on special non-convex plane domains. In particular, this yields that there are many differentiable functions on plane domains that do not satisfy the Mean Value Theorem.Plan Andaluz de Investigación (Junta de Andalucía)Ministerio de Economía y Competitividad (MINECO).

Procesos de decisión de Markov para comunicaciones selectivas con distribuciones de importancia dependientes

Las redes de sensores inalámbricos son una tecnología prometedora que conlleva necesidades específicas al respecto de gestión de recursos energéticos. En este proyecto se ha afrontado el diseño de estrategias de transmisión selectiva para redes de sensores inalámbricos utilizando secuencias de mensajes caracterizados por importancias con dependencia estadística entre importancias de mensajes consecutivos, modelando las decisiones del nodo mediante un Proceso de Decisión de Markov. Se ha observado el comportamiento selectivo óptimo según dicho modelo para distribuciones simples, identificando patrones repetidos para energía alta y deduciendo la expresión teórica para dicha tendencia asintótica. Se ha aplicado dicho modelo a dos situaciones distintas: importancias consecutivas con dependencia estadística que se transmiten o descartan e importancias independientes sobre las que la decisión es transmitir o acumular en el nodo. Finalmente, se ha tratado de proponer soluciones subóptimas eficientes, implementables con información estadística incompleta y se ha comparado la e ciencia de estas estrategias frente a la óptima y frente a nodos no selectivos.Wireless sensor networks are a promising technology that entails specific needs regarding energetic resources management. In this proyect, the design of selective transmision strategies has been addressed in the context of nodes in a sensor network which receive messages characterized by a measure of its importance or utility to the network, considering there is statistical dependence between consecutive importances, and modelling the node decision by means of a Markov Decision Process. The optimal selective behaviour on this model has been observed for simple distributions of importances, identifying patterns for high energy and deriving a theoretical expresion for that asymptotic tendency. Two di erent cases have been studied with this model: statistical dependence between importances of messages arriving to the node which are either transmitted or discarted and independent importances that are transmitted or accumulated in the node. Finally, we have tried to propose suboptimal efficient solutions, which are easy to implement on real nodes with incomplete statistical information, comparing the behaviour of this suboptimal strategies with the optimal one and not selective nodes.Ingeniería de Telecomunicació
