The on-line coupled atmospheric chemistry model system MECO(n) – Part 5: Expanding the Multi-Model-Driver (MMD v2.0) for 2-way data exchange includin…
2018
Abstract. As part of the Modular Earth Submodel System (MESSy), the Multi-Model-Driver (MMD v1.0) was developed to couple online the regional Consortium for Small-scale Modeling (COSMO) model into a driving model, which can be either the regional COSMO model or the global European Centre Hamburg general circulation model (ECHAM) (see Part 2 of the model documentation). The coupled system is called MECO(n), i.e., MESSy-fied ECHAM and COSMO models nested n times. In this article, which is part of the model documentation of the MECO(n) system, the second generation of MMD is introduced. MMD comprises the message-passing infrastructure required for the parallel execution (multiple programme mul…
Stolen innocence? Observance of the EU Directive on presumption of innocence by Spanish crime reporting
2021
This paper examines the compliance of Spanish crime reporting with the principles of the 2016 EU Directive on presumption of innocence, which aims at preventing the publication of information that might bias the public and the jurors against the suspect. A content analysis applied to a sample of 200 crime news stories published by eleven of the most popular print and online news platforms in 2018 reveals that the Spanish press coverage of crime is centered around the pre-trial and sentence stages, with little attention to the oral trial. The full name and the face portrait of the suspect appear in roughly one-third of the stories, but this overwhelmingly happens in news stories reporting on…
Early Jurassic (Sinemurian to basal Toarcian) ammonites of the Brescian Prealps (Southern Alps, Italy).
2017
This work provides a more precise up-to-date biostratigraphical framework of the Early Jurassic ammonite succession of the Brescian Prealps with more than seventy taxa for the Sinemurian, Pliensbachian and basal Toarcian corresponding to a about 30 horizons or faunal assemblages rather well correlable with the NW European standard zonation. These results are supported with already published data, new data from recent field investigations, revised contributions of different authors and with the study of the historical collection of the Museum of Natural Sciences of Brescia (Northern Italy). The biohorizons are referred to the Lower Jurassic carbonate series of the Brescian Prealps, cropping …
Discrepancies between archaeological and 14C-based chronologies: problems and possible solutions
2018
14C dating of bone collagen is believed to produce the most reliable absolute dates for the Central European Early Neolithic, as the selection of bones in anatomical context minimises taphonomic problems. In contrast, a comparison of three newly published local or regional chronological models as well as a comparison of several series of dates from bone collagen, charcoal and cereals highlights problems probably caused by diagenetic influences, especially on collagen. Therefore, at least the checking of bone collagen 14C dates against charcoal or cereal dates from the same contexts seems to be indispensable.
Comparative analysis of atmospheric radiative transfer models using the Atmospheric Look-up table Generator (ALG) toolbox (version 2.0)
2019
Abstract. Atmospheric radiative transfer models (RTMs) are software tools that help researchers in understanding the radiative processes occurring in the Earth's atmosphere. Given their importance in remote sensing applications, the intercomparison of atmospheric RTMs is therefore one of the main tasks used to evaluate model performance and identify the characteristics that differ between models. This can be a tedious tasks that requires good knowledge of the model inputs/outputs and the generation of large databases of consistent simulations. With the evolution of these software tools, their increase in complexity bears implications for their use in practical applications and model interco…
Polar motion prediction using the combination of SSA and Copula-based analysis
2018
The real-time estimation of polar motion (PM) is needed for the navigation of Earth satellite and interplanetary spacecraft. However, it is impossible to have real-time information due to the complexity of the measurement model and data processing. Various prediction methods have been developed. However, the accuracy of PM prediction is still not satisfactory even for a few days in the future. Therefore, new techniques or a combination of the existing methods need to be investigated for improving the accuracy of the predicted PM. There is a well-introduced method called Copula, and we want to combine it with singular spectrum analysis (SSA) method for PM prediction. In this study, first, we…
Human capital in Spain and its distribution by provinces (1964-2013)
2015
The regularly-updated database “Human capital in Spain and its distribution by provinces” provides information about the accumulation of human capital in Spain over the last five decades. The human capital estimates included in this database contain a wide range of information on how education levels in Spain have evolved, classified according to the level of studies completed and other human capital indicators. The database includes information that has been updated until the second trimester of 2013. It can be accessed at http://www.ivie.es/en/banco/caphum/series.php.
More firms, more competition? The case of the fourth operator in France's mobile phone market
2010
Accepted, Forthcoming; International audience; To foster competition the French government authorized a fourth operator, ‘Free', to enter the country's mobile phone market at the end of 2009 alongside Orange, SFR and Bouygues Telecom (BT), who held respectively one-half, one-third and one-sixth of the market. By using a stylized model of France's phone market, we have examined what we call the regulator's nightmares and dreams. If Cournot competition is in place before Free's entry, minimizing the total profit fails to maximize the consumer surplus and the total surplus; the maximum most realistic price fall is 6.7% compared to three-way competition and could be 1.7% only; if Orange, SFR an…
Mobile telephony in emerging markets: The importance of dual-SIM phones
2020
Abstract A substantial share of customers in emerging markets use dual-SIM phones and subscribe to two mobile networks. A primary motive for so called multi-simming is to take advantage of cheap on-net services from both networks. In our modelling effort, we augment the seminal model of competing telephone networks á la Laffont, Rey and Tirole (1998b) by a segment of flexible price hunters that may choose to multi-sim. According to our findings, in equilibrium, the networks set a high off-net price in the linear tariffs to achieve segmentation. This induces the price hunters to multi-sim. We show that increased deployment of dual-SIM phones may induce a mixing equilibrium with high expected…
Análisis del repertorio musical en los manuales escolares
2021
Una de las concreciones de la pedagogía crítica en la educación musical es la utilización de un repertorio que incorpore las preferencias del alumnado. En este estudio se aborda la presencia de dicho repertorio en los manuales escolares más utilizados en la actualidad. Para ello, se ha accedido a 15 libros de texto, analizando 985 piezas distintas. Las variables empleadas han sido el período histórico o género musical, el estilo dentro del repertorio de la música popular urbana, la antigüedad del autor y la tipología de propuesta didáctica asociada. Los resultados indican que la música popular urbana tiene una escasa presencia en los manuales (8.20%) y no coincide con las preferencias de lo…
