    Non-decoupling effects of SUSY in the physics of Higgs bosons and their phenomenological implications

    Get PDF
    We consider a plausible scenario in the Minimal Supersymmetric Standard Model (MSSM) where all the genuine supersymmetric (SUSY) particles are heavier than the electroweak scale. In this situation, indirect searches via their radiative corrections to low energy observables are complementary to direct searches, and they can be crucial if the SUSY masses are at the TeV energy range. We summarize the most relevant heavy SUSY radiative effects in Higgs boson physics and emphasize those that manifest a non-decoupling behaviour. We focus, in particular, on the SUSY-QCD non-decoupling effects in fermionic Higgs decays, flavour changing Higgs decays and Yukawa couplings. Some of their phenomenological implications at future colliders are also studied.Comment: Invited talk given by M. J.

    A partir del tratamiento del personaje del Duque de Borbón en la Comedia del saco de Roma de Juan de la Cueva, se analizan los intereses dramáticos y políticos del autor -evidenciados al compararlos con los sucesos históricos-, así como sus motivos para revivir un acontecimiento cuyo significado era de especial interés en el contexto político de 1580.Concentrating on the characterisation of the Duke of Bourbon in the Comedia del saco de Roma of Juan de la Cueva, this analysis focuses on the dramatic and political intentions of the author that become apparent when the play is compared with the historical events. The significance of Cueva's motives in reviving this historical event in the political context of 1580 is also examined

    ¿Es la depresión un factor de riesgo para el desarrollo de la demencia en las personas mayores?

    [Resumen] Introducción: La depresión y la demencia repercuten negativamente en la calidad de vida de las personas mayores, además de generar un gran gasto sociosanitario. Los estudios llevados a cabo en los últimos años reconocen que existe relación entre ambos trastornos. Aclarar esta relación permitirá conocer si la depresión es un factor de riesgo para el posterior desarrollo de la demencia. Material y métodos: Se realizó una búsqueda bibliográfica en diferentes bases de datos como Medline, Pscynfo, Isi Web Of Knowledge, Isi Web Of Science y PubMed, además de consultarse diversos libros. La búsqueda incluyó los términos depresión, demencia, prevalencia y personas mayores. Las publicaciones y estudios seleccionados están comprendidos entre los años 2000 y 2013. Todos los artículos seleccionados están incluidos en revistas científicas con clasificación Journal Citation Report (JCR). Resultados: La mayoría de los estudios seleccionados para esta revisión, apoyan la hipótesis de que la depresión es un factor de riesgo para el desarrollo de demencia. A su vez, reconocen que existe una relación temporal entre ambos trastornos. Sólo dos de los estudios encontrados no apoyan dicha relación. Conclusiones: Se ha encontrado que existe relación entre ambos trastornos y que la depresión se asocia con un mayor riesgo de desarrollar demencia.[Abstract] Background: Depression and dementia negatively impact in the quality of life of the elderly, generating at the same time a large social and health spending. Studies carried out in recent years recognize that there is a relationship between depression and dementia. Clarify this relationship will allow to know whether depression is a risk factor for later development of dementia. Method: The bibliography search was conducted in different databases such as Medline, Pscynfo, Isi Web Of Knowledge, Isi Web of Science and PubMed, besides consulting several books. The search included the terms depression, dementia, prevalence and the elderly. The publications and selected studies are comprised between 2000 and 2013. All selected articles are included in scientific journals with Journal Citation Report (JCR) classification. Results: Most of the selected studies support the hypothesis that depression is a risk for developing dementia. In turn, recognize that there is a temporal relationship between the two disorders Only two of the studies found no support that relationship. Conclusions: It is found that there is a relationship between both disorders and that depression is associated with an increased risk of developing dementia.Traballo fin de mestrado (UDC.FCS).

    Spatial projection of input-ouput tables for small areas

    Studies on regional economy have achieved a huge expansion in the last decades. In particular, from an input-ouput optic many efforts have been devoted to carring out a suitable methodology, which enable us to cover the overall and exhaustive knowledge of the economic reality of one region. Given that a input-output table (IOT) gathers both intersectorial relationships and the final demand of the economy, it allows us to provide a reliable picture of one economy in a certain moment of time. Nonetheless, the elaboration of a IOT is a complex task, which needs many human and economic resources. Thus, most of the tables elaborated using direct methods have as a benchmark frame either a country or a region, although it is difficult to find matrices related to smaller geografic spaces like, for instance, counties. So, if we attempt to perform a deeper study of both spaces, it would be of great help if we could dispose of estimation methods, which enable us to make tables with less information, i.e, indirect (semidirect) methods of estimation. Let´s say that the economy of a region is determined by the relations among productive structures of their counties, therefore a previous knowledge of these productive structures can be interesting. The basic aim of this work consists of estimating a TIO for each one of the eight Asturian Counties in 1995, since this is the last period in which we possess published information relative to regional accounts. To this end, a technique focused on mathematical theory of the information: cross entropy, will be employed. Such a technique has lately been applied to the construction of regional tables, largely for two reasons: one, flexibility as regards the information it needs; the other, to produce some rather suitable empiric results. From the tables estimates by this method we will be able to know the characteristics of economic structures of the counties. To achieve this scope, tools related to the graph theory, have been applied. Their application in input-output analisis has a great potential to provide a simple vision of the relations between the different sectors, as well as being able to integrate matters as important as the relative positions of the sectors, their orientation or paths in which drive the economic influence inside the corresponding structure.

    Welfare Benefits in Highly Decentralized Fiscal Systems: Evidence on Interterritorial Mimicking

    Get PDF
    This paper analyzes the determinants of welfare benefit levels within a highly fiscally decentralized context. More specifically, we analyze the role of mimicking as a driver of the institutional design of subnational government policies in the absence of federal co-ordination and financing. Empirically we focus on the welfare benefit programs of Spanish regional governments during the period 1996-2015. Our results strongly support the significant role played by mimicking: regional public agents observe what their peers are doing and act accordingly, and this takes place even in a context of low mobility of households. Moreover, we find evidence of vertical externalities: even in a completely decentralized framework, regions consider the benefits set by the central government as a benchmark when determining their own welfare benefit level
