Tariff diversity and competition policy: drivers for broadband adoption in the European Union

While second-degree price discrimination is standard in commercial practice in many industries, consumer advocates and public interest groups have reacted with skepticism against tendencies to move away from flat rates and introduce greater tariff diversity. This paper provides an empirical analysis how the differentiation of broadband tariffs with respect to retail prices affects fixed broadband subscription using time-series data. The empirical analysis is based on a unique dataset of 10,200 retail broadband offers spanning the 2003-2011 period and including 23 EU member states. Results show that an increase in tariff diversity provides a significant impetus to broadband adoption, wherefore demands by some public interest groups to limit price discrimination in broadband markets should be viewed with some caution as reduced price discrimination may come at the cost of lower penetration rates

The natural regeneration of calcareous grassland at a landscape scale: 150 years of plant community re-assembly on Salisbury Plain, UK

Questions: What is the time-scale for natural regeneration of calcareous grassland? Is this time-scale the same for individual plant species, plant community composition and functional traits? Location: Defence Training Estate Salisbury Plain, Wiltshire, UK. Methods: We investigated the rate of natural regeneration of species-rich calcareous grassland across a 20 000-ha landscape. We combined a large-scale botanical survey with historic land-use data (6–150 yrs before present) and examined differences between grassland age classes in the occurrence of individual plant species, plant community composition and plant community functional traits. Results: Many species showed a significant association with grasslands over 100 yrs old. These included the majority of those defined elsewhere as calcareous grassland indicators, although some appeared on grasslands <10 yrs old. Plant community composition showed increasing similarity to the oldest grasslands with increased grassland age, with the exception of very recently ex-agricultural grasslands. Most functional traits showed clear trends with grassland age, with dispersal ability differing most strongly between recent and older grasslands, whilst soil fertility and pH tolerance were more influential over longer time-scales. Conclusions: Even in a well connected landscape, natural regeneration to a community resembling ancient calcareous grassland in terms of functional traits and plant community composition takes over a century, although changes at the level of individual species may occur much earlier. These findings confirm the uniqueness of ancient calcareous grassland. They also suggest that the targets of re-establishment efforts should be adjusted to account for the likely time-scale of full community re-assembly

Una inscripción republicana de la sede de una posible corporación en La Cabañeta (El Burgo de Ebro, Zaragoza): nuevos datos sobre la ocupación romana del valle del Ebro

This paper faces the study of a Latin Roman republican inscription made on an opus signinum floor. This script speaks about two magistri being in charge of a work. Also, the features of text, and the structure of building in witch it has been found, induce us to think that we are dealing with the office of an Italic immigrant corporation, probably dedicated to trade.En este trabajo se estudia una inscripción realizada en un pavimento de opus signinum. El texto alude a una obra realizada al cuidado de dos magistri. El epígrafe y el tipo de edificio en el que apareció, nos inducen a pensar que nos encontramos ante la sede de una corporación de inmigrantes itálicos, dedicados con toda probabilidad al comercio

Oxigenación por membrana extracorpórea (ECMO): Experiencia inicial de nuestro centro en adultos con insuficiencia respiratoria aguda grave

[spa] La oxigenación por membrana extracorpórea (ECMO) es una forma de soporte vital extracorpóreo. Un circuito o sistema de cir- culación artificial externo conduce sangre venosa desde el paciente a un oxigenador, donde se añade oxígeno y se desprende dióxido de carbono, y a continuación, la sangre se devuelve a la circulación del paciente. Dependiendo de si su configuración es venovenosa (VV) o venoarterial, la ECMO se utiliza como apoyo temporal de la función respiratoria, de la función circulatoria o de ambas. El objetivo de este artículo es presentar la experiencia inicial del hospital universitario Son Espases (Palma) con el sistema ECMO VV al tratarse del único centro en las Islas Baleares capaz de ofrecer dicho tratamiento

Oxigenación por membrana extracorpórea (ECMO): experiencia inicial de nuestro centro en adultos con insuficiencia respiratoria aguda grave

Extracorporeal membrane oxygenation (ECMO) is a form of extracorporeal life support. An external artificial circulation or circuit carries venous blood from the patient to an oxygenator, where oxygen is added and carbon dioxide removed, then the blood is returned to the patient circulation. Depending on its configuration –venovenous (VV) or venoarterial–, ECMO is temporarily used to support respiratory function, circulation, or both. The objective of this publication is to review the initial experience at Son Espases University Hospital (Palma) using VV ECMO, unique centre in the Balearic Island with the capability of providing this therapy.La oxigenación por membrana extracorpórea (ECMO) es una forma de soporte vital extracorpóreo.
