Ciudadanos y culturas mediáticas: ocultos en la formalidad democrática
Estamos ante un modo de comprender la relación entre comunicación, cultura y política, ampliando los sentidos de la dimensión social de la vida. Se evidencian diferentes procesos de inclusión mediática que asumen los ciudadanos receptores de medios en diferentes campos. Se recupera así el concepto de mediación aplicable al campo de interacciones entre miradas disciplinarias varias, como entre ofertas y lecturas que se hacen de ella. Los sentidos de pertenencia apelan niveles individuales y climas colectivos que se instalan y mueven constantemente, generando cambios. Para ello, la asociación cultura-sociedad es especialmente destacada, permitiendo entender posicionamientos ante el poder. Mediaciones que siendo culturales son también sociales y especialmente políticas. Así el concepto de democracia aparece reinterpretado por las audiencias evidenciado diversidades ocultas por el ejercicio político formal. El texto levanta el telón para evidenciar mundos subjetivos de reinterpretación De esa manera se identifican distintas ubicaciones y definiciones de ciudadanía. Se evidencian desplazamientos entre información y placer, más allá de un simple análisis de contenidos.We are facing a way of understanding the relationship between communication, culture and politics, broadening the meanings of the social dimension in life. Different processes of media inclusion are evidenced, and they are assumed by media receptors in different fields. This way, a concept of mediation applicable to the field of interactions among varied disciplinary glances and among the offers and readings made of them, is recovered. The feelings of belonging appeal to individual levels and collective atmospheres that are installed and move constantly, generating changes. In this process, the culture and society association is especially outstanding, allowing the under-standing of positioning with regards to power. These mediations are cultural, but they are also social and, especially, political. Thus, the concept of democracy emerges reinterpreted by the audiences, evidencing hidden diversities by the formal political exercise. The text raises the curtain to evidence subjective worlds of reinterpretation. This way different locations and definitions of citizenship are identified. Movements between in-formation and pleasure are evidenced beyond a simple content analysis
A Survey on q-Polynomials and their Orthogonality Properties
In this paper we study the orthogonality conditions satisfied by the
classical q-orthogonal polynomials that are located at the top of the q-Hahn
tableau (big q-jacobi polynomials (bqJ)) and the Nikiforov-Uvarov tableau
(Askey-Wilson polynomials (AW)) for almost any complex value of the parameters
and for all non-negative integers degrees. We state the degenerate version of
Favard's theorem, which is one of the keys of the paper, that allow us to
extend the orthogonality properties valid up to some integer degree N to
Sobolev type orthogonality properties. We also present, following an analogous
process that applied in [16], tables with the factorization and the discrete
Sobolev-type orthogonality property for those families which satisfy a finite
orthogonality property, i.e. it consists in sum of finite number of masspoints,
such as q-Racah (qR), q-Hahn (qH), dual q-Hahn (dqH), and q-Krawtchouk
polynomials (qK), among others.

Citizens and media cultures: hidden behind democratic formality
The relationship between culture and mass media has received much attention among communication scholars in Latin America, especially during the 1980s and 1990s. This period witnessed a shift from understanding culture and mass communication as domination, to an exploration of the complex and politically nuanced roles played by the mass media within the cultural and political fabrics of the region. As such, the ideological and deterministic moorings of the old debates were considerably softened, as writers such as Martín-Barbero redefined the media in terms of cultural mediations. From this perspective, cultural mediations shape the manner in which subjects articulate their relationship to modernity. This article continues this agenda by exploring the complex relationship between culture, politics and democracy

The Spanish technical change : a regional and a dynamic analysis (1994-2007)
Studying wage dispersion, many researchers have found that the skill premium (the ratio of skilled workers¿ wages to unskilled ones) has increased after 1979 in many developed countries, when there was a very sharp increase in the supply of skilled workers. The recent consensus is that technical change favours skilled workers, replacing tasks previously performed by the unskilled and exacerbating inequality. In the Spanish case, Nuñez and Alfaro (2009) have found evidences of a decline in the wage premium during the nineties. So, in this paper, we distinguish between skilled and unskilled workers differentiating the efficiency units of both types of workers. Moreover, we calculate the Spanish technology frontier and the technology differences between the Spanish Regions in 2006 and we analyze the evolution of the Spanish technology frontier over 1994-2007, testing the kind of technical change. In addition, a coherent Spanish wage micro-data base is achieved, using data from Eurostat: ECHP and EU-SILC

Sistema de apoyo a la decisión para transpante de páncreas en pacientes con diabetes tipo 1 basado en modelado de datos
This master thesis is focused on the development of a clinical decision support system to help
Clinicians on the decision about pancreas and kidney transplant in patients with
type 1 Diabetes Mellitus.
To do so, an exploratory data analysis has been performed using a group of 82 patients,
which have been transplanted in La Fe health department between 2002 and 2015. This
analysis allows to describe the sample population and all the variables from the study. Among them, the most significant indicators are
used for developing a classification model to predict the transplant success and failure. Afterwards, the model is integrated into a distributed system so the users can interact with the model through a web interface. The information exchange is performed as means as an orchestrated system, implemented as an
distributed and autonomous system to predict the pancreas loss with a 82,9% accuracy with a short group of variables.Este proyecto se centra en el desarrollo de un sistema de ayuda a profesionales sanitarios en la toma de decisión respecto a la realización de trasplantes de páncreas y riñón en pacientes con Diabetes Mellitus tipo 1.
Se ha realizado un análisis exploratorio del conjunto de datos de 82 pacientes sometidos a trasplante de páncreas y riñón entre los años 2002 y 2015 en el departamento de salud La Fe. Este análisis permite determinar la presencia de indicadores del éxito o fracaso de la intervención. Los indicadores más significativos son utilizados para el desarrollo de un modelo de clasificación que permite realizar predicciones en función de los datos de entrada de un nuevo paciente. El usuario accede al modelo a través de un interfaz web y el intercambio de información se realiza mediante un sistema de comunicaciones basado en la orquestación de servicios.
Con todo esto, se ha conseguido implementar un sistema distribuido y autónomo que permite predecir antes de realizar la intervención, en base a un número reducido de variables, si un paciente trasplantado es susceptible de perder el páncreas a largo plazo con una precisión del 82,9 %.Moreno Alfaro, P.

Citizens’ media in latin america
There are several reasons that explain why community and citizens’ media are so widespread and popular in Latin America. This chapter offers a series of short vignettes set in Colombia that describe the intricate processes that developed there since the 1920s and simultaneously elsewhere across Latin America, spreading the notion that agency and participation are everyone’s right. These vignettes highlight why understanding community and citizens’ media in Latin America requires recognizing the long history of radical politics in the region and the wide dissemination of leftist ideologies that popularized notions of popular participation and political agency as rights. The chapter also brings into dialogue the work of Peruvian scholar Rosa María Alfaro, who was instrumental in transforming communication scholarship in Latin America and is an early example of citizens’ media in Latin America. Including a translation of this key early text by Alfaro was a challenge, because the field is vast and there is so much material that has never been translated into English or published outside of Latin America. In selecting the following piece, the intention is to maintain the centrality of both theory and practice and to show how citizens’ media in Latin America cannot be understood unless we take into consideration what social movements and grassroots communities did in the region and how Latin American scholars thought about the region
