    En este trabajo se analiza el contexto familiar de sujetos de altas capacidades en una muestra de 530 escolares de 10 a√Īos de edad. Se identificaron 45 sujetos superdotados, 64 sujetos con talento creativo, 6 sujetos superdotados con talento creativo y 15 sujetos de altas capacidades. El nivel cultural materno, el tipo de centro y el estilo educativo asertivo aparecen como variables asociadas a los contextos familiares de los ni√Īos superdotados. El nivel cultural materno unido al hecho de no trabajar fuera de casa aparecen asociados a los contextos familiares de ni√Īos con talento creativo y a los contextos de ni√Īos superdotados y a la vez creativos. La inadaptaci√≥n social aparece asociada a los contextos de ni√Īos con altas capacidades. Palabras clave: contexto familiar y altas capacidades.This study analyzes the family context of high capacity children in a sample of 530 10-year-old school children. 45 gifted subjects were identified alongside 64 with creative talent, 6 who were both gifted and possessed creative talent and 15 high capacity subjects. Maternal cultural level, type of school attended and assertive parenting style were identified as variables associated with the family contexts of gifted children. Maternal cultural level, linked to the mother not working outside the home, was found to be associated with the family contexts of children with creative talent, as well as to those of children who were both gifted and highly creative. Social inadaptation was associated with high capacity children. Key words: family context and gifted children

    The implementation of the Digital Terrestrial Television is becoming a reality in the Spanish territory. In this context, with the satellite and cable systems, this technology is one of the possible mediums for the television signal transmission. Its development is becoming crucial for the digital transition in those countries which mainly depend on the terrestrial networks for the reception of multimedia contents. However, due to the maturity of the current standard, and also to the higher requirements of the customer needing (HDTV, new contents, etc.), a revision of the current standard becomes necessary. The DVB organisation in collaboration with other entities and organisms has developed a new standard version capable to satisfy those requirements. The main objective of the project is the design and implementation of a physical layer simulation platform for the DVB-T2 standard. This simulator allows the theoretical evaluation of the new enhanced proposals, making easier a later field measurement stage and the future network deployment. The document describes the implementation of the simulation platform as well as its subsequent validation stage, including large graphical results that allow the evaluation and quantification of the improvements introduced over the current standard version (DVB-T). On the other hand, and as future investigation lines, a solution for the future DVB-T2 network deployment is performed, enhancing the coverage capacity of the current network by the use of iterative meta-heuristic techniques. Finally it has to be mentioned that this work has been performed within the context of a project called FURIA, which is a strategic research project funded by the Spanish Ministry of Industry, Tourism and Commerce

    Digital Terrestrial Television Broadcasting (DTTB) is a member of our daily life routine, and nonetheless, according to new users’ necessities in the fields of communications and leisure, new challenges are coming up. Moreover, the current Standard is not able to satisfy all the potential requirements. For that reason, first of all, a review of the current Standard has been performed within this work. Then, it has been identified the needing of developing a new version of the standard, ready to support enhanced services, as for example broadcasting transmissions to moving terminals or High Definition Television (HDTV) transmissions, among others. The main objective of this project is the design and development of a physical layer simulator of the whole DVB-T standard, including both the complete transmission and reception procedures. The simulator has been developed in Matlab. A detailed description of the simulator both from a functional and an architectural point of view is included. The simulator is the base for testing any possible modifications that may be included into the DVB-T2 future standard. In fact, several proposed enhancements have already been carried out and their performance has been evaluated. Specifically, the use of higher order modulation schemes, and the corresponding modifications in all the system blocks, have been included and evaluated. Furthermore, the simulator will allow testing other enhancements as the use of more efficient encoders and interleavers, MIMO technologies, and so on. A complete set of numerical results showing the performance of the different parts of the system, are presented in order to validate the correctness of the implementation and to evaluate both the current standard performance and the proposed enhancements. This work has been performed within the context of a project called FURIA, which is a strategic research project funded by the Spanish Ministry of Industry, Tourism and Commerce. A brief description of this project and its consortium has been also included herein, together with an introduction to the current situation of the DTTB in Spain (called TDT in Spanish)

    Occupations and the recent trends in wage inequality in Europe

    Get PDF
    We aim to contribute to a better understanding of the role that occupations played in recent trends in wage inequality in some European countries. Using EU-SILC data, we observe that most of the changes in wage inequality between 2005 and 2014 were the result of changes in the distribution of wages within occupations. A longer term approximation using data from the Luxembourg Income Study (LIS) shows similar patterns. We conclude that occupational dynamics did not drive recent trends in wage inequality in Europe

    Family Context, Parenting and Child Development: An Epigenetic Approach

    Get PDF
    This paper presents an essay that uses an epigenetic approach to attain an inclusive and in-depth understanding of the influence of family context and quality of parenting on children’s psychological development. Based on the identification of a key developmental process in which interactions are continuously internalised, the approach draws attention to the bidirectional and systemic nature of intrafamily and parenting interactions and highlights the multiple factors that influence them, which are linked to the developmental history of the species, the individual characteristics of both the child and their parents, and contextual variables. In response to these internalised interactions, the body activates epigenetic mechanisms, such as DNA methylation, which may affect the phenotypic expression of the genome. Theoretical and methodological implications are discussed in light of the current process of identifying the biological profiles underlying negative and positive parenting practices. Some insights are offered regarding the challenges and opportunities that parents and policymakers should address in the 21st century in connection with the promotion of positive parenting, taking into account the epigenetic processes triggered by adverse environments for children and their families.This research was funded by the Vice-rectorate for Research at the University of the Basque Country, UPV/EHU, postdoctoral research grant DOKBERRI 2020-I, grant number DOCRE20/04

    Parenting styles and adolescent adjustment

    Get PDF
    En este art√≠culo se presentan los resultados de un estudio realizado sobre una muestra de 848 adolescentes de edades comprendidas entre los 12 y los 17 a√Īos, que cumplimentaron un cuestionario que inclu√≠a una escala con 6 dimensiones sobre su percepci√≥n del estilo parental o relacional materno y paterno y otros instrumentos para evaluar el ajuste adolescente. La realizaci√≥n de un an√°lisis de conglomerados a partir de las puntuaciones en las 6 dimensiones que compon√≠an la escala revel√≥ la existencia de tres grupos de padres y de madres que fueron definidos como democr√°ticos, estrictos e indiferentes. El trabajo ofrece un modelo de categorizaci√≥n de las relaciones entre padres e hijos que posee un car√°cter bidireccional y que incluye dimensiones como la revelaci√≥n, el humor y la promoci√≥n de autonom√≠a, que enriquecen la perspectiva cl√°sica basada exclusivamente en las dimensiones de afecto y disciplina. El estilo materno y el paterno fueron evaluados por separado encontr√°ndose una alta coincidencia entre ambos estilos, que adem√°s mostraron una relaci√≥n muy significativa con el ajuste de chicos y chicas.The paper presents the results of a study with a sample of 848 adolescents between 12 and 17 years who completed a questionnaire that included a 6 dimensions scale about their perception of maternal and paternal educational style and other measures of adolescent adjustment. The results of cluster analysis showed 3 groups of mothers and fathers that were defined as: authoritative, strict, and indifferent. The study has permitted us to create a bi-directional model which categorises the relationships between parents and adolescents and which includes factors such as self-disclosure, sense of humour and the encouragement of adolescent independence. These factors enrich the traditional perspective based solely on affection and discipline. The parenting style of mothers and fathers, evaluated separately, showed a high coincidence and furthermore showed a significant relationship with adolescent well-being.Ministerio de Ciencia y Tecnolog√≠a BSO2002-0302

    Wage differentials and segmentation: The impact of institutions and changing economic conditions.

    Get PDF
    This paper uses data from the European Survey on Income and Living Conditions to offer new empirical evidence on how wage differentials are influenced by the changing economic conditions, that is, before and after the 2008–2010 recession, and shaped by the different institutional frameworks of European Union countries. We examine whether wage changes are homogeneous across groups of workers, as they are classified by their contractual relationship and working time, and by the heterogeneity in institutions that regulate and affect the labour market. Results obtained by estimating ordinary least squares and quantile regressions confirm the existence of contract and working time wage gaps and allow to estimate their different magnitudes along the wage distribution, and their rise during the recession. The impact of labour market institutions on shaping them is diverse, with more intervention of the government in the setting of the minimum wage and stricter regulation for atypical contracts reducing the wage gaps and producing larger positive effects for low-wage employees
