Representing Data Visualization Goals and Tasks through Meta-Modeling to Tailor Information Dashboards

[EN] Information dashboards are everywhere. They support knowledge discovery in a huge variety of contexts and domains. Although powerful, these tools can be complex, not only for the end-users but also for developers and designers. Information dashboards encode complex datasets into different visual marks to ease knowledge discovery. Choosing a wrong design could compromise the entire dashboard’s effectiveness, selecting the appropriate encoding or configuration for each potential context, user, or data domain is a crucial task. For these reasons, there is a necessity to automatize the recommendation of visualizations and dashboard configurations to deliver tools adapted to their context. Recommendations can be based on different aspects, such as user characteristics, the data domain, or the goals and tasks that will be achieved or carried out through the visualizations. This work presents a dashboard meta-model that abstracts all these factors and the integration of a visualization task taxonomy to account for the different actions that can be performed with information dashboards. This meta-model has been used to design a domain specific language to specify dashboards requirements in a structured way. The ultimate goal is to obtain a dashboard generation pipeline to deliver dashboards adapted to any context, such as the educational context, in which a lot of data are generated, and there are several actors involved (students, teachers, managers, etc.) that would want to reach different insights regarding their learning performance or learning methodologies.SIMinisterio de Economía y Competitividad (TIN2016-80172-R)Ministrio de Educación, Cultura y Deporte (FPU17/03276

Extending a dashboard meta-model to account for users’ characteristics and goals for enhancing personalization

[EN]Information dashboards are useful tools for exploiting datasets and support decision-making processes. However, these tools are not trivial to design and build. Information dashboards not only involve a set of visualizations and handlers to manage the presented data, but also a set of users that will potentially benefit from the knowledge generated by interacting with the data. It is important to know and understand the requirements of the final users of a dashboard because they will influence the design processes. But several user profiles can be involved, making these processes even more complicated. This paper identifies and discusses why it is essential to include the final users when modeling a dashboard. Through meta-modeling, different characteristics of potential users are structured, thus obtaining a meta-model that dissects not only technical and functional features of a dashboard (from an abstract point of view) but also the different aspects of the final users that will make use of it. By identifying these user characteristics and by arranging them into a meta-model, software engineering paradigms such as model-driven development or software product lines can employ it as an input for generating concrete dashboard products. This approach could be useful for generating Learning Analytics dashboards that take into account the users' motivations, beliefs, and knowledge

Methodology to assess the maximum irrigation rates at regional scale using geostatistics and GIS

Ponencia presentada en la Conference of Agricultural Engineering celebrada en Valencia del 8 añ 12 de julio de 2012Soil water holding capacity is an important parameter for irrigation scheduling and water balance modelling in fields. In the framework of precision irrigation the knowledge of the spatial distribution of this parameter is useful to advice the maximum irrigation rate specifically for each field in an irrigation district, region, etc. The soil water holding capacity (SWHC) can be assessed as the soil water content between the field capacity (FC) and the permanent wilting point (PWP). In this work, we present a methodology to assess the spatial distribution of the maximum irrigation rate depending on the soil water holding capacity. This methodology combines geostatistic techniques with geographical information system-GIS tool. A pilot zone of 12 400 ha located in the Palancia river lowland (between Valencia and Castellón province, Spain) in which the main irrigated crops are citrus (53.8 %), and vegetables (13.3 %), was selected to develop this methodology. For spatial modelling of SWHC, experimental semivariograms were assessed for the FC and PWP at three soil depth intervals (0-10, 10-30, 30-60 cm). Spherical models fitted well to the experimental semivariograms, with a very high spatial dependency index (ID = 0.05-0.41) which support reliable predictions on basis the fitted models. The cokriging spatial interpolation method, considering the percentage of sand as secondary variable, was the best option to minimize the root mean square error in the cross-validation test.Peer Reviewe

Use and value of music as a didactic tool in Primary School Education

La música se ha considerado tradicionalmente como una herramienta didáctica valiosa en el proceso enseñanza-aprendizaje de los estudiantes. Son mínimos los estudios empíricos realizados sobre el uso y la valoración de la música como un recurso transversal en el ámbito escolar. En esta investigación han participado un total de 258 docentes (74,2% mujeres y 25.8% hombres) en activo de Educación Primaria de la Comunidad de Castilla y León (España). El 74,4% de los participantes desempeñan su trabajo en colegios públicos y un 67.1% tienen 10 o más años de experiencia. Se trata de un estudio descriptivo transversal presentado mediante encuesta a través de un cuestionario ad hoc en el que los docentes deben reflexionar sobre el uso y valoración de la música en sus clases. Los resultados muestran que existen diferencias en el uso de la música en función de las áreas en donde se imparte docencia; así es muy frecuente su uso en Inglés, Plástica, Educación Especial/Audición y Lenguaje o en Religión/Valores Sociales y Cívicos, y poco frecuente en asignaturas como Ciencias de la Naturaleza o Matemáticas. El 90% de los maestros encuestados que cuentan con formación musical especializada, hacen un uso habitual de la música en sus clases, frente al 51% de los que no la tienen. El 85% de los docentes encuestados, considera que, en general, la música está insuficientemente valorada en la etapa. Por último, se discuten los datos y se justifica la necesidad de mejorar la formación musical de los maestros a la luz de la utilidad y beneficios que esta supone en la formación integral de los niños.Music has traditionally been considered as a valuable didactic tool in the teaching-learning process of students. The empirical studies carried out on the use and evaluation of music as a transversal resource in the school environment are minimal. A total of 258 teachers (74.2% women and 25.8% men) in active Primary Education in the Community of Castilla y León (Spain) have participated in this research. 74.4% of the participants carry out their work in public schools and 67.1% have 10 or more years of experience. This is a descriptive cross-sectional study presented by means of a survey through an ad hoc questionnaire in which the respondents had to reflect on the use and assessment of music in their classes. The results show that there are differences in the use of music depending on the areas where teaching is taught; thus, its use is very frequent in English, Plastic, Special Education / Hearing and Language or in Religion / Social and Civic Values, and infrequent in subjects such as Natural Sciences or Mathematics. 90% of the teachers surveyed and who have specialized musical training make regular use of music in their classes, compared to 51% of those who do not. 85% of the teachers surveyed consider that, in general, music is insufficiently valued in the stage. Finally, the data are discussed and the need to improve the musical training of teachers is justified in light of the usefulness and benefits that this entails in the comprehensive training of children

Analyzing the usability of the WYRED Platform with undergraduate students to improve its features

[EN]The WYRED ecosystem is a technological ecosystem developed as part of WYRED (netWorked Youth Research for Empowerment in the Digital society), a European Project funded by the Horizon 2020 program. The main aim of the project is to provide a framework for research in which children and young people can express and explore their perspectives and interests concerning digital society. The WYRED ecosystem supports this framework from a technological point of view. The WYRED Platform is one of the main software components of this complex technological solution; it is focused on supporting the social dialogues that take place between children, young people and stakeholders. The ecosystem, and in particular the Platform, are already developed, but it is vital to ensure the acceptance by the final users, the children and young people mainly. This work presents the usability test carried out to evolve the Platform through the System Usability Scale. This usability test allows the identification of the weaknesses of the Platform regarding its characteristics, also allowing the corresponding improvement of the WYRED Platform, and it will serve as a reference for further usability testin

Antibodies to endothelial cells in Behçet's disease: cell-binding heterogeneity and association with clinical activity

OBJECTIVES--To investigate the prevalence and characteristics of antibodies to endothelial cells (aEC) from large vessel and from microvasculature in a group of patients with Behçet's disease (BD) to determine the relationship of these antibodies with clinical and laboratory features of the disease. METHODS--Thirty patients with BD were prospectively and consecutively studied. The aEC were determined by enzyme-linked immunosorbent assay (ELISA) using endothelial cells derived from human umbilical vein (large vessel) as well as from retroperitoneal adipose tissue (microvasculature). RESULTS--Fifteen patients (50%) had aEC, either directed to large vessel [8(26%) patients] or microvascular [13(43%) patients] endothelial cells. The percentage of active patients was significantly higher in the aEC-positive group [12(80%) patients] compared with the aEC-negative group [5(33%) patients] (p < 0.05). CONCLUSIONS--Patients with BD have a high prevalence of aEC when microvascular endothelial cells are used in the assay. These antibodies seem to be a marker of disease activity in this condition, previously considered as negative for autoantibodies

Thrombophlebitis associated to neoplasia. Evaluation of 23 cases

Se describen las características clínicas de una serie de 23 pacientes (13 varones, 10 mujeres) de edad media 61 ± 14 años, afectos de trombotlebitis paraneoplásica. Las trombotlebitis fueron recurrentes y migratorias en el 61 % de los casos, en el 70 % se localizaron en las extremidades interiores y en el 83 % precedieron al diagnóstico histológico de la neoplasia. Al detectarse la tromboflebitis existían signos y síntomas sugestivos de neoplasia en el 84 % de los casos. El cáncer de pulmón en el varón y el de ovario en la mujer fueron losasociados con mayor frecuencia; en el 91 % de los casos el tipo histológico fue carcinoma y en el 90 % se evidenciaron metástasis. En 2 pacientes se asoció una endocarditis trombótica no bacteriana (ETNB) en el. estudio necrópsico. El tratamiento con heparina fue ineficaz en la mitad de los pacientes y en el 39 % de los casos se produjo un tromboembolismo pulmonar (TEP) a pesar de la descoagulación. La comparación de la serie con los 4.817 pacientes neoplásicos del registro de tumores de nuestro hospital no mostró diferencias en cuanto al sexo y edad. Se constató asimismo que las neoplasias que con mayor frecuencia se asociaron a tromboflebitis fueron las de mayor prevalencia en la serie general
