Reseña: "La democràcia electrònica", de Jordi Sànchez i Picanyol

The first title in the "Vull Saber" series, La democràcia electrònica (e-Democracy) written by the political scientist Jordi Sànchez, represents a highly relevant work as it deals with a very current subject matter which can be of interest not only to politicians and public authorities, butalso to any citizen who uses new technologies and wishes to gain greater insight into the impact that technological changes have on the world of politics. Each title in the series aims to provide an introduction to a subject by condensing the most relevant information over a limited number of pages. The book invites us to reflect on the potential of the Internet to transform the political system of representative democracy and sets out the most important events that have occurred in this ambit: e-voting, open parliaments, online forums, citizen consultations, two-way communication between politicians and citizens, etc. Throughout the book, there are many useful links and Web page references to different issues surrounding e-democracy. In November 2005, the UOC's virtual Campus hosted a virtual debate focusing on the contents of the book and open to all members of the UOC community. The level of participation in the debate (more than 60 participants) highlighted the interest surrounding information and communication technologies as new social and political tools.El primer número de la colección «Vull Saber» titulado La democràcia electrònica y escrito por el politólogo JordiSànchez resulta muy pertinente porque el tema es de gran actualidad y puede interesar tanto a políticos y auto-ridades como a cualquier ciudadano que utilice las nuevas tecnologías y quiera conocer el impacto de los cambios tecnológicos en el mundo político. En pocas páginas, dado que el objetivo de la colección es concentrar la información más relevante para comprender un tema, el libro nos hace reflexionar sobre las potencialidades de Internet para transformar y mejorar la democracia representativa y presenta las experiencias más importantes que se han desarrollado en este ámbito: voto electrónico, parlamentos abiertos, foros en línea, consultas ciudadanas, comunicación bidireccional entre políticos y ciudadanos, etc. Resulta útil también porque a lo largo del libro se recogen numerosas webs y enlaces sobre las diversas experiencias que tienen un impacto transformador en nuestros sistemas políticos. Dado el interés de estos temas, del 14 al 22 de noviembre del 2005 se emprendió un debate virtual sobre el contenido del libro y en el que podían participar los miembros de toda lacomunidad UOC. El debate y la presentación del libro se situó en el nuevo espacio Comunidad/Actividades/Presentaciones Virtuales del Campus. La importante participación en el debate (más de 60 participantes) demuestra el interés que despiertan las nuevas tecnologías de la información y la comunicación como nuevas herramientas políticas y sociales

The Transition to College Process in PR-CETP Scholars

This article describes a study about the experiences of a group of students during the transition from high school to college. The students are future teachers who evidenced a high level of academic achievement in high school and received merit scholarships from the Puerto Rico Collaborative for Excellence in Teacher Preparation (PR-CETP). Two groups of students were compared: those who sustained a high GPA during their freshman year, and those who did not and, therefore, no longer qualified for the scholarship. The study was carried out through focused interviews with eight students, from three universities, four of whom maintained the scholarship and four who did not. Findings indicate that the main problems encountered were academic and social, and that the students received support from their families during the entire process. Regarding formal support, they pointed out that they felt highly satisfied with the services provided by PR-CETP and the universities, but they also pointed out (particularly those who lost the scholarship) that they needed additional services from the universities. They suggested, for example, better tutoring, and social activities among the scholars. The interviewed students, in general, consider that they faced the transition successfully since most of them described their academic, emotional, and social status as satisfactory at the time of the interviews

Four temptations against urban renewel: an approach to fur current urban processes

Comunicación presentada en 25 European Network housing Research International Conference. Tarragona 19 al 22 junio 2013The new paradigm of urban social and economic rehabilitation is replacing the current sprawl growth model. But four temptations must be considered: 1) The high-density. This process is possible in sprawl model, but its quantification does not seem to be clear, because after a certain threshold of occupancy per unit area, the city seems to collapse and social and environmental benefits disappear, appearing reversal processes city to country in search of a minimum quality of life standards. There is not a model for appropriate density. It depends on the way of life of population, the traditional city model. 2) The replacement. Architectonic and urban rehabilitation must be preferred to replacement, except for certain cases to be legally taxed. But as the city cannot be densified and orderly, without the prior replacement of the building, may fit this temptation. Even replacing the building can be made without considering high building standards 3) The gentrification. There is a wide doctrine and experience about this phenomenon with serious social consequences. It is very tempting to replace the building, due to improve requirement of broad levels of quality, entering a game of speculation, so common in our real estate market. 4) The eco-city. Comprehensive projects are building spaces with low levels of energy consumption. Fall into this temptation means to continue the extensive city model we have been developing, creating new cities far from the existing but incorporating saving measures, and continuing resource consumptio

Political Polarisation and Network Leaderships in the Catalan Parliamentarians Twitter Network

This article seeks to test if Twitter is opening communication flows between parties and paving the way for the appearance of network leaderships or if it is reducing them to representatives of the same party or ideology and empowering party leaders. The study is based on a dataset spanning from 1 January 2013 to 31 March 2014 which covers all relationships (4,516), retweets (6,045) and mentions (19,507) of Catalan parliamentarians. The data sustain that the political polarisation of Catalan parliamentarians¿ Twitter flows is deeper in the relationship and retweet networks than it is in the mention and that even if party leaders are still at the centre of communication flows, other parliamentarians are taking the floor and becoming network leaders.Este artículo trata de probar si Twitter abre flujos de comunicación entre partidos distintos y allana el camino para la aparición de liderazgos en la red o si los reduce a representantes del mismo partido o ideología y empodera a los líderes del partido. El estudio se basa en un conjunto de datos que abarca desde 1 de enero de 2013 al 31 de marzo de 2014 e incluye todas las relaciones (4516), retweets (6045) y menciones (19.507) de los parlamentarios catalanes. Los datos sostienen que la polarización política de los parlamentarios catalanes en los intercambios de Twitter es más profunda en las redes de relaciones y las redes de retweets que en las redes de menciones y que, aunque los líderes del partido se encuentran todavía en el centro de los flujos de comunicación, otros parlamentarios están tomando la palabra y se están convirtiendo en líderes en la red

Echo Chambers in Parliamentary Twitter Networks:The Catalan Case

Social media is transforming relations among members of parliaments, but are members taking advantage of these new media to broaden their party and ideological communication environment, or they are mainly communicating with other party members and ideologically aligned peers? This article tests whether parliamentarians’ use of Twitter is opening communication flows or confining them to representatives of the same party or ideology. The study is based on a data set spanning the period January 1, 2013, to March 31, 2014, which covers all relations (4,516), retweets (6,045), and mentions (19,507) among Catalan parliamentarians. Our results indicate that communication flows are polarized along party and ideological lines. The degree of polarization of this network depends, however, on where the interactions occur: The relations network is the most polarized; cross-party and cross-ideological interactions are greater in the retweet network and most present in the mention network

Determinación de los factores sobre la adherencia y cumplimiento convencional de TBC, Cotabamba, Apurímac, 2015-2017

La tuberculosis es la segunda enfermedad social infectocontagiosa responsable de producir mortalidad principalmente en adultos, la Organización Mundial de la Salud (OMS) estima, que aproximadamente un tercio de la población mundial se encuentra infectada por el Mycobacterium tuberculosis. Así mismo la tuberculosis multidrogo resistente hoy en día es un gran problema de salud pública que enfrenta como obstáculo para su control, el abandono de tratamiento, que aumenta la morbimortalidad, expone a mayor contagio y genera resistencia bacteriana, afectando a la sociedad. Sin embargo la tuberculosis es una enfermedad curable, con un diagnóstico rápido y tratamiento oportuno, que resultan fundamentales para su control. El presente informe tiene por finalidad evidenciar la evaluación y seguimiento que se realiza al paciente con diagnóstico de tuberculosis en la estrategia sanitaria de prevención y control de la tuberculosis de la red de salud Cotabambas, ApurímacTrabajo academic

Moldura de cal de los arcos de herradura del Aljibe de la Casa de las Veletas de Cáceres, España / Lime moulding on horseshoe arches on the “casa de las veletas" water tank at cáceres, Spain

Se describen las características constructivas de los enlucidos de cal de las fábricas de ladrillo de los arcos de herradura del aljibe de la Casa de las Veletas de Cáceres, que formó parte del desaparecido alcázar musulmán, y que es uno de los más grandes de la Península. Está construido con muros de tapial que delimitan una planta rectangular de 136,80 m2 de superficie, y su datación está en torno a los siglos X a XII. Durante el estudio se tomaron muestras de morteros y pinturas de distintas superficies del recinto con la finalidad de caracterizar los materiales registrados en la lectura de paramentos, y que fueron analizados por IRFT. Sin embargo, la presencia de una moldura de cal aplicada sobre el enlucido también de cal de un arco de la nave 2, plantea la hipótesis de que el aljibe tenía decoraciones y que tal vez tuvo un uso anterior diferente. La causa por la que las decoraciones no se han documentado en estudios anteriores, podría basarse en que la desaparición de las molduras se produjo hace siglos, a causa de una erosión hídrica, por la acción del impacto del agua de lluvia, y porque los arcos permanecieron sumergidos durante un tiempo que no se ha determinado, hasta una altura de 3,60 m aproximadamente, según la marca del nivel de agua existente, produciéndose la desagregación de los morteros de cal y consiguiente desmoronamiento. / The article describes the characteristics of the lime plaster on the brick masonry horseshoe arches in the water tank to the “Casa de la Veletas” at Cáceres. The tank, one of the largest on the Iberian peninsula, formed part of a Muslim fortress that has since disappeared. Its rammed earth walls, dating from the tenth to the eleventh centuries, describe a 136,80 m2 rectangle. During the survey, mortar and paint samples were taken from a number of surfaces in the enclosure for subsequent FTIR analysis. In light of the presence of lime moulding on the likewise lime plaster in one of the nave 2 arches, the tank may presumably have been decorated and perhaps initially put to a different use. The reason that such decoration was not documented in prior studies may be that the moulding disappeared centuries ago due to erosion resulting from the impact of rainwater, and because, judging from the existing watermarks, the arches were submerged to an approximate height of 3,60 m for an unknown length of time. The combination of these two factors would have caused the lime mortar to crumble and the moulding to eventually collapse

Sistema constructivo del aljibe almohade de la casa de las veletas de Cáceres

Se analiza el sistema constructivo, estructura y acabados, del aljibe de época almohade de la Casa de las Veletas de Cáceres, cuya datación está en torno a los siglos X a XII. Cconstruido en base a once columnas y un pilar, son de ladrillo los dieciséis arcos de herradura levantados en dirección NE-SO, y las cinco bóvedas de cañón, que descansan sobre los mismos. Los muros son de tapia tipo tabiya, los enlucidos de cal, y el hallazgo de una moldura plantea la hipótesis de la existencia de decoraciones, por lo que originariamente pudo haber tenido otro uso. Los estudios se apoyan en la documentación histórica, lectura muraria y caracterización de morteros por FTIR
