La toma de decisiones como competencia transversal: taller para estudiantes de Educación Social

La toma de decisiones no solo es un proceso que se realiza de forma continua, en el día a día de cada persona, sino que además se trata de una competencia transversal. Lo le dota de un carácter genérico para la gran mayoría de las profesiones, y se hace necesaria para el buen desenvolvimiento en el mundo laboral. Se convierte así, en una importante característica para la empleabilidad. Esto incluye a los estudiantes de educación social, los cuales necesitarán adquirir un buen aprendizaje para el trabajo socioeducativo que tendrán que llevar a cabo, puesto que será imprescindible saber analizar problemas y tomar una decisión para solventarlos. Por ello, en el presente Trabajo de Fin de Grado, se estudia la toma de decisiones y se realiza una propuesta de intervención para el trabajo de ésta como competencia transversal, que se debe potenciar en los educadores y educadoras sociales.Decision-making is not only a process carried out on a continuously, in the day-to-day life of each person, it is also a traversal competence. This gives it a generic character for most professions and becomes necessary to develop in the world of work. For this, it becomes an important feature for employability. This includes social education students, who need a good learning from it and be able to carry out their socio-educational work; in this occupation, they need to analyze problems and make decisions to solve them. For these reasons, in this final dissertation decision-making is studied and it makes a proposal of intervention to be developed with faculty students. Finally, this decision-making is considered as a transversal competence that should be empowered by social educators.Grado en Educación Socia

Deportes minoritarios. Auge, evolución y tratamiento mediático

El periodismo deportivo actual ha evolucionado hacia el entretenimiento y espectáculo, en detrimento de la información y rigurosidad. Además, deja de lado éxitos y noticias importantes de algunos deportes, anteponiendo otras que lo son menos. El presente Trabajo de Fin de Grado se propuso la realización de un reportaje audiovisual con la finalidad de ofrecer diferentes puntos de vista de profesionales de la comunicación y deportistas que lo viven o lo vivieron desde dentro. ¿Son los medios quienes lo imponen o es la gente quién reclama estos contenidos? Este trabajo se realizó con el objetivo de mostrar cómo los medios han podido minorizar deportes que tienen muchos seguidores y cómo no han puesto apenas soluciones para sacar del atolladero a los que eran minoritarios desde el principio. Todo esto se hizo observando el origen y la evolución de los deportes que se consideran minoritarios. A raíz de ahí el trabajo se centró en el análisis del tratamiento de los medios, y cómo han tenido que reinventarse para no caer aún más en el olvido.Current sports journalism has evolved towards entertainment and spectacle, to the detriment of information and rigour. In addition, it sets aside successes and important news from some sports, putting others that are less so. The present Final Degree Project proposed the creation of an audiovisual report with the purpose of offering different points of view of communication professionals and athletes who live it or lived it from within. Is it the media that imposes it or is it the people who claim these contents? This work was carried out with the aim of showing how the media have been able to minority sports that have many followers and as they have hardly put solutions to remove from the pit those who were minority since the beginning. This was done by observing the origin and evolution of sports that are considered a minority. As a result, the work focused on the analysis of media treatment, and how they had to reinvent themselves in order not to fall further into oblivion.Departamento de Historia Moderna, Contemporánea y de América, Periodismo y Comunicación Audiovisual y PublicidadGrado en Periodism

Imagen hiperespectral de fluorescencia aplicada al estudio de tejidos vegetales

Treballs Finals de Grau de Química, Facultat de Química, Universitat de Barcelona, Any: 2018, Tutores: Anna de Juan Capdevila, Mónica Marro SánchezPlant tissues have natural fluorophores on their structure. When plants are exposed to an environmental stress, plant morphology, structural elements and content of fluorophores may vary. Three population of Oryza Sativa (rice) samples grew under control and stress conditions (watered with cadmium 50 μM and 1000 μM solutions). Fluorescence imaging allowed monitoring natural fluorophores such as chlorophylls or lignins in leave tissues. The information from fluorescence imaging was interpreted by the chemometric tool multivariate curve resolution alternating least squares (MCR – ALS) method which provides the pure fluorescence signatures and distribution maps of the fluorophores presents in the plants analyzed. Plants exposed to cadmium were more yellow indicating a lower concentration of chlorophylls. In leaves cross-sections, biological structures seem to be weaker than in non-contaminated plants. The leaf length also decreased in Cd-exposed populations. The fluorescence signatures and distribution maps of three types of chlorophyll and two lignin compounds were resolved. The use of fluorescence imaging techniques combined with chemometric tools are useful to obtain relevant biological, morphological and chemical information about compounds presents in plant tissues

Geomatic methods applied to the change study of the la Paúl Rock Glacier, Spanish Pyrenees

Producción CientíficaRock glaciers are one of the most important features of the mountain permafrost in the Pyrenees. La Paúl is an active rock glacier located in the north face of the Posets massif in the La Paúl glacier cirque (Spanish Pyrenees). This study presents the preliminary results of the La Paúl rock glacier monitoring works carried out through two geomatic technologies since 2013: Global Navigation Satellite System (GNSS) receivers and Terrestrial Laser Scanning (TLS) devices. Displacements measured on the rock glacier surface have demonstrated both the activity of the rock glacier and the utility of this equipment for the rock glaciers dynamic analysis. The glacier has exhibited the fastest displacements on its west side (over 35 cm yr-1), affected by the Little Ice Age, and frontal area (over 25 cm yr-1). As an indicator of permafrost in marginal environments and its peculiar morphology, La Paúl rock glacier encourages a more prolonged study and to the application of more geomatic techniques for its detailed analysis.Ministerio de Economía, Industria y Competitividad - Fondo Europeo de Desarrollo Regional (project CGL2015-68144-R)Junta de Extremadura - Fondo Europeo de Desarrollo Regional (project GR10071

Implementación del coaching en el programa de Seguridad Basado en el Comportamiento (SBC) para la reducción de incidentes/accidentes en el transporte de materiales peligrosos en la empresa Cargo Transport S.A.C.

El transporte de carga por medio terrestre es una de las actividades con altos números de accidentes e incidentes en la actualidad debido a los diversos factores que influyen en esta tarea. Si a esto se le añade el transporte de materiales peligrosos como los hidrocarburos (combustible), explosivos y lubricantes la probabilidad de que se maximice el evento es elevado y perjudicial para todos los actores externos e internos de la actividad. En el Perú existen leyes y normativas que regulan el transporte de materiales peligrosos, así como también el cumplimiento total de cada una de estas. Por ello, que las empresas brindan las capacitaciones y condiciones a los trabajadores que desempeñan esta labor, sin embargo, existe un factor elemental para evitar la ocurrencia de accidentes/incidentes la cual está arraigada al comportamiento del trabajador; así como también a la motivación y concientización de realizar sus actividades de forma segura. En este contexto, el presente trabajo de investigación plantea la implementación del Coaching en el Programa de Seguridad Basada en el Comportamiento (SBC) para disminuir los accidentes e incidentes, así como también para aumentar las conductas seguras de los trabajadores dentro de una empresa de transporte de materiales peligrosos. Este proyecto ejecutará el diseño y la aplicación del Coaching en el área de operaciones que se encuentra relacionada directamente al transporte de los materiales peligrosos.Freight transportation by land is one of the activities with high numbers of accidents and incidents today due to the various factors that influence this task. If to this is added the transport of hazardous materials such as hydrocarbons (fuel), explosives and lubricants, the probability that the event will be maximized is high and detrimental to all the external and internal actors of the activity. In Peru there are laws and regulations that regulate the transport of hazardous materials, as well as the full compliance with each of these. Therefore, the companies provide training and conditions to workers who perform this work, however, there is an elementary factor to avoid the occurrence of accidents / incidents which is rooted in the behavior of the worker; as well as the motivation and awareness to carry out their activities safely. In this context, this research work proposes the implementation of Coaching in the Behavior Based Safety Program (SBC) to reduce accidents and incidents, as well as to increase the safe behaviors of workers within a transportation company of hazardous materials. This project will execute the design and application of Coaching in the area of operations that will be directly related to the transport of hazardous materials.Tesi

Snowfall events in the Cantabrian Mountains of northwestern Spain: WRF multiphysics ensemble assessment based on ground and multi-satellite observations

[EN] Snowfall in elevated areas of the mid-latitudes has a strong impact on infrastructure, freshwater availability, and the climate system. The Cantabrian Mountains of the northwestern Iberian Peninsula are very vulnerable to climate change because of their moderate altitudes, which limits their snowfall. Monitoring snow events is essential for the evaluation of weather and climate prediction models. However, measurement networks are scarce in mountainous areas and have great uncertainties because of blizzards. In this study, a multiphysics ensemble of the Weather Research and Forecasting (WRF) model was designed using three microphysics and two planetary boundary layer (PBL) schemes to simulate nine snowfall events in the Cantabrian Mountains during autumn and winter 2021–2022. The WRF was validated using several snow characteristics, such as liquid water equivalent, snow cover, and snow depth. Liquid water equivalent was evaluated using snow-gauge networks and satellite products in an assessment of snow cover. In addition, a monitoring network of webcams and snow poles was implemented, improving the low density of snow observations in the mountains. The results showed good model performance for detection of snow cover and slight overestimation of liquid water equivalent and snow thickness, which may have been caused by under-catchment that is generally an effect of wind on the measurement systems and by snow compaction, respectively. Morrison microphysics and Mellor-Yamada-Nakanishi-Niino (MYNN PBL) yielded better results for liquid water equivalent at higher altitudes and output greater snow cover. The results help determine the best configurations for snow modelling in the study area to develop future studies of the spatiotemporal patterns of snow distribution.S

Electrical conductivity of metal (hydr)oxide–activated carbon composites under compression. A comparison study

[EN]From a granular commercial activated carbon (AC) and six metal (hydr)oxide precursors, including Al(NO3)3, Fe(NO3)3, SnCl2, TiO2, Na2WO4 and Zn(NO3)2, a broadly varied series of metal (hydr)oxideeAC composites were prepared by wet impregnation and subsequent oven-drying at 120 C. Here, the electrical conductivity of the resulting products was studied under moderate compression. The influence of the applied pressure, sample volume, mechanical work, and density of the hybrid materials was thoroughly investigated. The dc electrical conductivity of the compressed samples was measured at room temperature by the four-probe method. Compaction assays show that the mechanical properties of the composites are largely determined by the carbon matrix. Both the decrease in volume and the increase in density under compression were very small and only significant at pressures lower than 100 kPa for AC and most composites. By contrast, the bulk electrical conductivity of the hybrid materials was strongly influenced by the nature, content and intrinsic conductivity of the supported metal phases, which act as insulating thin layers thereby hindering the effective electron transport between AC cores of neighbouring sample particles in contact under compression. Conductivity values for the composites were lower than for the raw AC, all of them falling in the range of typical semiconductor materials. The patterns of variation of the electrical conductivity with pressure and mechanical work were slightly similar, thus suggesting the predominance of the pressure effects rather than the volume one

Temperature dependence of dc electrical conductivity of activated carbon–metal oxide nanocomposites. Some insight into conduction mechanisms

[EN] From a commercial activated carbon (AC) and six metal oxide (Al2O3, Fe2O3, SnO2, TiO2, WO3 and ZnO) precursors, two series of AC–metal oxide nanocomposites are prepared by wet impregnation, ovendrying at 120 °C, and subsequent heat treatment at 200 or 850 °C in inert atmosphere. The temperaturedependent dc electrical conductivity of AC and the as-prepared nanocomposites is measured from room temperature up to ca. 200 °C in air atmosphere by the four-probe method. The decrease in conductivity for the hybrid materials as compared to AC is the result of a complex interplay between several factors, including not only the intrinsic conductivity, crystallite size, content and chemical nature of the supported nanoparticles, which ultimately depend on the precursor and heat treatment temperature, but also the adsorption of oxygen and water from the surrounding atmosphere. The conductivity data are discussed in terms of a thermally activated process. In this regard, both AC and the prepared nanocomposites behave as semiconductors, and the temperature-dependent conductivity data have been interpreted on the basis of the classical model proposed by Mott and Davis. Because of its high content of heteroatoms, AC may be considered as a heavily doped semiconductor, so that conduction of thermally excited carriers via acceptor or donor levels is expected to be the dominant mechanism. The activation energies for the hybrid materials suggest that the supported metal oxide nanoparticles strongly modify the electronic band structure of AC by introducing new trap levels in different positions along its band gap. Furthermore, the thermally activated conduction process satisfies the Meyer–Neldel rule, which is likely connected with the shift of the Fermi level due to the introduction of the different metal oxide nanoparticles in the AC matrix

The trilinear constraint adapted to solve data with strong patterns of outlying observations or missing values

The possibility to perform trilinear decompositions of data sets has the clear advantage of providing unique solutions. Excitation-emission fluorescence matrices (EEM) are the best known paradigm of chemical measurements providing a trilinear structure associated with the configuration of excitation, emission and sample modes. Chemometric tools, such as Parallel Factor Analysis (PARAFAC) and Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) with trilinear constraint, assist in solving the mixture analysis problem by exploiting the trilinear behavior of the EEM measurements. However, the spectroscopic nature of EEM measurements makes that no emission signal can be recorded below the current excitation wavelength, generating a strong and systematic pattern of outlier (zero observations) in EEM data that challenges the classical analysis by MCR-ALS or PARAFAC. Several approaches have been proposed to deal with this problem, such as the identification of outlying values below the excitation wavelength and, thus, the use of data imputation in PARAFAC, but they show severe limitations when systematic outlying data patterns occur. In this paper, we propose a new implementation of the trilinear constraint in MCR-ALS algorithm to cope with EEM measurements where a strongly patterned of outlying data is present. This approach preserves the trilinear property and does not require any data imputation step to replace the outlying observations. Its performance is tested on simulated data, controlled pharmaceutical mixtures and hyperspectral images of a plant tissue (HSI). It should be noted that the approach proposed is applicable to EEM data, where a systematic pattern of outlying observations exist, but can be generalized to the treatment of any trilinear data set with a strong pattern of missing values
