Nueva economĂa 20+20
276 p : il.El fuerte avance de las TecnologĂas de la InformaciĂłn y las Comunicaciones (TIC) ha provocado profundos cambios econĂłmicos, sociales y culturales en las Ășltimas dĂ©cadas (Cohen, De Long y Zysman, 2000). La gran velocidad con la que se ha producido este cambio ha quedado reflejada en cifras, como el avance de Internet que, desde 1969, fecha de su nacimiento, hasta la actualidad, se ha extendido a mĂĄs del 25% de la poblaciĂłn mundial, con mĂĄs de 1.700 millones de usuarios en todo el mundo, siendo especialmente significativos los casos de Europa y Estados Unidos, con penetraciones del 52% y 74,2%, respectivamente (Internet World Stats, 2009). Es igualmente significativo el fuerte crecimiento experimentado por los ordenadores personales que, desde 1977, año en el que vio la luz el primero de ellos, se estima que alcanzaron los 1.000 millones en el 2008, y se hacen predicciones de que se doblarĂĄ dicha cifra en torno al año 2014 (Gartner, 2008).
El trabajo, el ocio, el transporte o, incluso, las relaciones personales se encuentran en un proceso de cambio permanente debido a la profunda influencia que estas tecnologĂas han tenido sobre la sociedad. Tanto es asĂ que en la nueva realidad, a la que el conocimiento y la tecnologĂa trasladan al ser humano, existen nuevas concepciones del tiempo o del espacio (Castells, 2005).
Desde el punto de vista econĂłmico, se han producido cambios en la estructura mundial que han desembocado en una nueva economĂa. Por una parte, las nuevas tecnologĂas han transformado la economĂa tradicional, dando lugar a una compleja estructura interconectada de forma global, en la que el desarrollo de las comunicaciones ha jugado un papel fundamental. Adicionalmente, la incorporaciĂłn de la tecnologĂa en el proceso productivo ha transformado elementos tales como la localizaciĂłn, el tamaño, las estructuras o las relaciones entre las empresas (Brynjolfsson y Kahln, 2000). Por otra parte, las nuevas tecnologĂas dan lugar a un nuevo mercado de enormes dimensiones, formado por todos aquellos bienes y servicios que dependen de forma crĂtica de las tecnologĂas digitales o lo son en sĂ mismas, lo cual constituye la base de la economĂa digital (Kling y Lamb, 1999).
Con todo ello, el presente informe se encarga, en primer lugar, de identificar en quĂ© consiste la economĂa digital y cuĂĄles son sus principales componentes. En el siguiente apartado se intenta medir la importancia de este sector, a travĂ©s de los datos mĂĄs significativos, que reflejan el crecimiento que dicho sector de la economĂa ha sufrido en los Ășltimos años, y la importancia relativa del mismo respecto al resto de los sectores. A continuaciĂłn se presenta una caracterizaciĂłn de los perfiles de empresa que constituyen la economĂa digital y se busca plantear, despuĂ©s, un modelo de variables significativas que nos permita medir de forma adecuada el sector.Esta publicaciĂłn ha contado con la cofinancia-

The ATLAS Eventindex using the HBase/Phoenix storage solution
The ATLAS EventIndex provides a global event catalogue and event-level metadata for ATLAS analysis groups and users. The LHC Run 3, starting in 2022, will see increased data-taking and simulation production rates, with which the current infrastructure would still cope but may be stretched to its limits by the end of Run 3. This talk describes the implementation of a new core storage service that will provide at least the same functionality as the current one for increased data ingestion and search rates, and with increasing volumes of stored data. It is based on a set of HBase tables, coupled to Apache Phoenix for data access; in this way we will add to the advantages of a BigData based storage system the possibility of SQL as well as NoSQL data access, which allows the re-use of most of the existing code for metadata integration
The social cost of chronic kidney disease in Italy
This study aims to estimate the mean annual social cost per patient with chronic kidney disease (CKD) by stages 4 and 5 pre-dialyses and cost components in Italy. The multicenter cross-sectional study included all adult outpatients in charge of the 14 main Nephrology Centers of Tuscany Region during 7 weeks from 2012 to 2013. Direct medical costs have been estimated using tariffs for laboratory tests, diagnostic exams, visits, hospitalization and prices for drugs. Non-medical costs included expenses of low-protein special foods, travel, and formal and informal care. Patients' and caregivers' losses of productivity have been estimated as indirect costs using the human capital approach. Costs have been expressed in Euros (2016). Totals of 279 patients in stage 4 and 205 patients in stage 5 have been enrolled. The estimated mean annual social cost of a patient with CKD were a,notsign7422 (+/- a,notsign6255) for stage 4 and a,notsign8971 (+/- a,notsign6503) for stage 5 (p < 0.05). Direct medical costs were higher in stage 5 as compared to stage 4; direct non-medical costs and indirect costs accounted, respectively, for 41 and 5 % of the total social cost of CKD stage 4 and for 33 and 9 % of CKD stage 5. In Italy, the overall annual social cost of CKD was a,notsign1,809,552,398 representing 0.11 % of the Gross Domestic Product. Direct non-medical costs and indirect costs were weighted on the social cost of CKD almost as much as the direct medical cost. Patients, their families and the productivity system sustain the burden of the disease almost as much as the healthcare system. © 2016, The Author(s)
