    This article analyzes the impact of the Information and Communication Technologies (ICT) on students with Down syndrome through the consult of scientific articles published during the 2008 to 2018 period, in five scientific journal databases utilized in the academic world. Through a descriptive and quantitative methodology, the most significant bibliometric data according to citation index is shown. Likewise, a methodology based on the analysis of co-words and clustering techniques is applied through a bibliometric maps, in order to determine the fields of scientific study. The results show that articles published have a medium-low index of impact. There are linked with the importance of using ICT with these students, from educational inclusion and accessibility perspective

    In the present survey, we have proceeded to the analysis of Roman mortars and paintings in two rooms from a villa at El Ruedo (Almedinilla, Cordoba ). They were used different techniques or procedures, such as: analysis granules size, X ray diffraction and scattering reflection. It has been noticed that materials of the different decorations correspond to different compositions provenient from different sites (different canters). As far as colours are concerned, they were established the different parameters which define them in every international system. The scattering reflection techniques allowed us to identify the pigments, emphasizing that their mixtures are usually based upon only in one colour, lighter or darker.En el presente trabajo se ha procedido al análisis de los morteros y pinturas romanas de dos estancias de la villa de El Ruedo (Almedinilla, Córdoba). Se han utilizado diferentes técnicas, tales como análisis granulométrico, difracción de rayos X y reflectancia difusa. Se ha podido constatar que los materiales de las diferentes decoraciones presentan diferentes composiciones y por tanto provienen de sitios diferentes (canteras diferentes). Con respecto al color se han obtenido los parámetros que lo definen en los distintos sistemas internacionales. La técnica de reflectancia difusa ha permitido la identificación de los pigmentos, poniendo de manifiesto que sus mezclas se basan normalmente en uno solo, aclarado o oscurecido

    ERPA International Congresses on Education 2018This paper refers to the European project Erasmus + ELEF (European Learning Environment Formats for Citizenship and Democracy, Reference number 580426). The aim of this project is to develop, implement, evaluate and replicate democratic and innovative learning environments (good practices) in both educational institutions and informal and community learning environments. In this context, over the course of a year, a number of experiences considered relevant have been selected, which constitute the sample of this research on good practices. This contribution presents the educational programme “Youth Parliament”. This is a project with a long history and whose main objective is to train responsible citizens, with the collaboration of various educational agents. The evaluation carried out by the Secondary Education teachers in training on the potentialities and limitations of the programme is shown, based on the experiences carried out in the participating educational centres during the academic year 2016-2017

    Social Vulnerability and Touristification of Historic Centers

    Get PDF
    Historic centers have su ered di erent processes of neglect, occupation, segregation, gentrification, and touristification as a result of changes in demand and policies. Currently, they are going through a homogenization process motivated by tourist pressure, which is causing the expulsion of the local population; this is a common topic of interest for media and political agendas, which requires scientific analysis. This research aims at identifying the winning and the losing tourist groups in the historic center of Seville. It is structured in two parts: a conceptual one based on the bibliographic review with which one wants to know how the current society responds to tourist pressure through defining and characterizing the processes of substitution of uses and inhabitants, and another empirical one in which the analysis of statistical indicators (demographic, economic, and residential) treated with Geographic Information System (GIS) allows us to measure the degree of existing vulnerability and analyze social and spatial e ects caused by the tourism in Sevill
