    El presente TFG lleva por título “Psicología Positiva. Fundamentos de la Psicología Positiva: programa de Inteligencia Social y Emocional”. El documento se encuentra estructurado en cinco grandes apartados y a lo largo de él se pretende hacer una revisión bibliográfica acerca de la Psicología Positiva, así como de los fundamentos sobre los que se apoya, para finalmente elaborar un programa educativo basado en esta corriente psicológica, y más concretamente sobre inteligencia social y emocional. A partir de la revisión global y teórica de este enfoque psicológico, se analizan los beneficios que puede tener en la educación y en las personas con discapacidad, y cómo un buen tratamiento de los aspectos positivos puede ayudar a alcanzar el bienestar personal y emocional. Finalmente el trabajo concluye con un programa educativo basado en la inteligencia social y emocional de personas con discapacidad intelectual, con el fin de contribuir a mejorar las relaciones interpersonales y exteriorización de los sentimientos.Grado en Educación Primari

    TRIQ: A Comprehensive Evaluation Measure for Triclustering Algorithms

    Get PDF
    Triclustering has shown to be a valuable tool for the analysis of microarray data since its appearance as an improvement of classical clustering and biclustering techniques. Triclustering relaxes the constraints for grouping and allows genes to be evaluated under a subset of experimental conditions and a subset of time points simultaneously. The authors previously presented a genetic algorithm, TriGen, that finds triclusters of gene expression dasta. They also defined three different fitness functions for TriGen: MSR3D, LSL and MSL. In order to asses the results obtained by application of TriGen, a validity measure needs to be defined. Therefore, we present TRIQ, a validity measure which combines information from three different sources: (1) correlation among genes, conditions and times, (2) graphic validation of the patterns extracted and (3) functional annotations for the genes extracted.Ministerio de Ciencia y Tecnología TIN2011-28956-C02-02Ministerio de ciencia y Tecnología TIN2014-55894-C2-1-RJunta de Andalucía P12-TIC-752

    LSL: A new measure to evaluate triclusters

    Get PDF
    Microarray technology has led to a great advance in biological studies due to its ability to monitorize the RNA levels of a vast amount of genes under certain experimental conditions. The use of computational techniques to mine hidden knowledge from these data is of great interest in research fields such as Data Mining and Bioinformatics. Finding patterns of genetic behavior not only taking into account the experimental conditions but also the time condition is a very challenging task nowadays. Clustering, biclustering and novel triclustering techniques offer a very suitable framework to solve the suggested problem. In this work we present LSL, a measure to evaluate the quality of triclusters found in 3D data

    MSL: A Measure to Evaluate Three-dimensional Patterns in Gene Expression Data

    Microarray technology is highly used in biological research environments due to its ability to monitor the RNA concentration levels. The analysis of the data generated represents a computational challenge due to the characteristics of these data. Clustering techniques are widely applied to create groups of genes that exhibit a similar behavior. Biclustering relaxes the constraints for grouping, allowing genes to be evaluated only under a subset of the conditions. Triclustering appears for the analysis of longitudinal experiments in which the genes are evaluated under certain conditions at several time points. These triclusters provide hidden information in the form of behavior patterns from temporal experiments with microarrays relating subsets of genes, experimental conditions, and time points. We present an evaluation measure for triclusters called Multi Slope Measure, based on the similarity among the angles of the slopes formed by each profile formed by the genes, conditions, and times of the triclusterMinisterio de Ciencia y Tecnología TIN2011-28956-C02-02Junta de Andalucía TIC-752

    Deep Learning Techniques to Improve the Performance of Olive Oil Classification

    Get PDF
    The olive oil assessment involves the use of a standardized sensory analysis according to the “panel test” method. However, there is an important interest to design novel strategies based on the use of Gas Chromatography (GC) coupled to mass spectrometry (MS), or ion mobility spectrometry (IMS) together with a chemometric data treatment for olive oil classification. It is an essential task in an attempt to get the most robust model over time and, both to avoid fraud in the price and to know whether it is suitable for consumption or not. The aim of this paper is to combine chemical techniques and Deep Learning approaches to automatically classify olive oil samples from two different harvests in their three corresponding classes: extra virgin olive oil (EVOO), virgin olive oil (VOO), and lampante olive oil (LOO). Our Deep Learning model is built with 701 samples, which were obtained from two olive oil campaigns (2014–2015 and 2015–2016). The data from the two harvests are built from the selection of specific olive oil markers from the whole spectral fingerprint obtained with GC-IMS method. In order to obtain the best results we have configured the parameters of our model according to the nature of the data. The results obtained show that a deep learning approach applied to data obtained from chemical instrumental techniques is a good method when classifying oil samples in their corresponding categories, with higher success rates than those obtained in previous works.Ministerio de Economía y Competitividad TIN2017-88209-C2-2-

    2005-2017 Ozone trends and potential benefits of local measures as deduced from air quality measurements in the north of the Barcelona metropolitan area

    Get PDF
    We analyzed 2005–2017 data sets on ozone (O3) concentrations in an area (the Vic Plain) frequently affected by the atmospheric plume northward transport of the Barcelona metropolitan area (BMA), the atmospheric basin of Spain recording the highest number of exceedances of the hourly O3 information threshold (180¿µg¿m-3). We aimed at evaluating the potential benefits of implementing local-BMA short-term measures to abate emissions of precursors. To this end, we analyzed in detail spatial and time variations of concentration of O3 and nitrogen oxides (NO and NO2, including OMI remote sensing data for the latter). Subsequently, a sensitivity analysis is done with the air quality (AQ) data to evaluate potential O3 reductions in the north of the BMA on Sundays compared with weekdays as a consequence of the reduction in regional emissions of precursors. The results showed a generalized decreasing trend for regional background O3 as well as the well-known increase in urban O3 and higher urban NO decreasing slopes compared with those of NO2. The most intensive O3 episodes in the Vic Plain are caused by (i) a relatively high regional background O3 (due to a mix of continental, hemispheric–tropospheric and stratospheric contributions); by (ii) intensive surface fumigation from mid-troposphere high O3 upper layers arising from the concatenation of the vertical recirculation of air masses; but also by (iii) an important O3 contribution from the northward transport/channeling of the pollution plume from the BMA. The high relevance of the local-daily O3 contribution during the most intense pollution episodes is clearly supported by the O3 (surface concentration) and NO2 (OMI data) data analysis. A maximum decrease potential (by applying short-term measures to abate emissions of O3 precursors) of 49¿µg¿O3¿m-3 (32¿%) of the average diurnal concentrations was determined. Structurally implemented measures, instead of episodically, could result in important additional O3 decreases because not only the local O3 coming from the BMA plume would be reduced, but also the recirculated O3 and thus the intensity of O3 fumigation in the plain. Therefore, it is highly probable that both structural and episodic measures to abate NOx and volatile organic compound (VOC) emissions in the BMA would result in evident reductions of O3 in the Vic PlainPeer ReviewedPostprint (author's final draft

    Introducción: los bifosfonatos son inhibidores de la resorción ósea e incrementan la densidad mineral del hueso. El aceite de oliva es antioxidante, antinflamatorio y favorece la neoformación ósea. Objetivo: Analizar el efecto de Alendronato(AL), Pamidronato(PA)y Aceite de Oliva(OL) en la remodelación ósea y evaluar los resultados de su asociación. Materiales y métodos: 144 ratas Wistar, machos de 160gr y 45 días de edad,se dividieron en 6 grupos: C(Control)recibió semanalmente, vía subcutánea en miembro posterior izquierdo 0,3 ml de solución salina cada 100g de peso. El grupo AL recibió semanalmente vía subcutánea en miembro posterior izquierdo 0,5 mg de Alendronato/Kg de peso. El grupo PA recibió 0,6 mg de Pamidronato/Kg. El grupo O recibió diariamente OL con el alimento y solución salina vía subcutánea. El grupo ALO recibió Alendronato subcutáneo y OL en la dieta. El grupo PAO recibió Pamidronato subcutáneo y OL en la dieta. Previa anestesia, se realizó una incisión en cada miembro posterior hasta exponer la tibia, donde se talló una cavidad. Se valoraron tiempos 0,7,15,30,60,90 días. Se realizaron estudios bioquímicos en sangre para determinar fosfatasa alcalina(FA).Se tomaron Radiografías para analizar Densidad óptica (DO).En cortes de tibia se realizó histología e histomorfometría. Se obtuvieron los fémures para ensayos Biomecánicos. Los datos fueron comparados mediante análisis de la Varianza (diferencias significativas p˂0,05) contemplando: tiempo, tibia y tratamiento. Resultados: FA mostró diferencias significativas entre grupos problema y C. Radiográficamente se hallaron diferencias en tiempo y tratamiento. Se observó incremento de DO en grupos problema respecto al C, destacándose PAO al día 15.Histológicamente se visualizó aumento en la cantidad y grosor de trabéculas en PAO al día15.La histomorfometría mostró incremento del porcentaje del hueso trabecular en PA y PAO a los 60 días. Estudios biomecánicos registraron los valores más elevados entre 60 y 90 días y tendencia al aumento de la rigidez en PAO. Conclusiones: existe correlación entre los resultados obtenidos. El aumento de FA correspondería a un aumento de la actividad osteoblástica. La DO aumentada señalaría proceso de neoformación ósea. El aumento de densidad trabecular indicaría aumento de la calidad del tejido neoformado. En todas las variables analizadas se encontraron diferencias estadísticamente significativas entre grupos problema y control. Este trabajo abre las puertas a futuras investigaciones para comparar datos o experimentar con distintas dosificaciones.2021-11-1
