    The COVID-19 health crisis has great media coverage in Spain. Thus, this paper analyses the journalistic treatment and the information bias that this media event received. A study of the semantic prosody of the term “coronavirus” in the digital edition of the newspaper El País during the 2020 state of alarm in Spain was carried out. The data obtained showed that this newspaper presented a negative information bias in the coverage and treatment of COVID-19, since it offered a high number of negative co-occurrences together with the term “coronavirus”.La crisis del COVID-19 ha tenido una gran repercusión mediática en España. Por consiguiente, el presente trabajo analiza el tratamiento periodístico y el sesgo informativo que ha recibido este suceso mediático. Para ello, se ha realizado un estudio de la prosodia semántica del término «coronavirus» en la edición digital del periódico El País durante el estado de alarma de 2020 en España. Los resultados obtenidos del estudio han reflejado que este periódico ha manifestado un sesgo informativo negativo en la cobertura y el tratamiento del COVID-19, ya que ha presentado un elevado número de coocurrencias negativas junto al término «coronavirus»

    Energy Efficiency Indicators for Assessing Construction Systems Storing Renewable Energy: Application to Phase Change Material-Bearing Façades

    Get PDF
    Assessing the performance or energy efficiency of a single construction element by itself is often a futile exercise. That is not the case, however, when an element is designed, among others, to improve building energy performance by harnessing renewable energy in a process that requires a source of external energy. Harnessing renewable energy is acquiring growing interest in Mediterranean climates as a strategy for reducing the energy consumed by buildings. When such reduction is oriented to lowering demand, the strategy consists in reducing the building’s energy needs with the use of construction elements able to passively absorb, dissipate, or accumulate energy. When reduction is pursued through M&E services, renewable energy enhances building performance. The efficiency of construction systems that use renewable energy but require a supplementary power supply to operate can be assessed by likening these systems to regenerative heat exchangers built into the building. The indicators needed for this purpose are particularly useful for designers, for they can be used to compare the efficiency or performance to deliver an optimal design for each building. This article proposes a series of indicators developed to that end and describes their application to façades bearing phase change materials (PCMs)

    During the harvesting period 1999-2000, real samples of two phases olive pomace were taken from storage ponds in two extraction facilities located in Southern region of Spain , every month until a maximum of five months. In addition, lots of two phases olive pomace and second-centrifuged two phases olive pomace were divided in closed recipients and, also, in opened recipients, and were stored in laboratory at 36 ºC for 0, 1, 2, 4 and 6 months. Samples were analysed for moisture and fat content, and solvent-extracted; the resulting oils were analysed for acidity, fatty acid composition, polar compounds and triglycerides. The results indicate that oil deterioration increases throughout the storage period, particularly those oils extracted from surface and from second-centrifuged two phases olive pomace. The surface/volume ratio in the ponds should be as low as possible. Special attention should be paid to the storage of two phases olive pomace, establishing a maximum of two months in all cases.Durante la campaña 1999-2000 se han tomado muestras reales de orujo de balsas de almacenamiento, cada mes hasta un máximo de 5 meses, y de lotes de orujo de dos fases almacenados en el laboratorio, en recipientes cerrados y abiertos, a 36 ºC durante 0, 2, 4 y 6 meses, correspondientes a masas centrifugadas una y dos veces (repasada). Se han analizado la humedad y riqueza grasa de las muestras y la acidez, composición en ácidos grasos, compuestos polares y triglicéridos de los aceites extraídos con disolvente. Los resultados indican que no es aconsejable el almacenamiento del orujo de dos fases en balsas por un tiempo superior a dos meses ya que podría suponer un serio detrimento a la calidad del aceite obtenido, siendo mayor en aquellos de masas centrifugadas dos veces (repasadas) y, sobre todo, en las zonas superficiales, por lo que las balsas deberían tener una relación superficie/volumen lo menor posible

    The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-38628-2_15n this paper we define a bidimensional extension of Stochastic Context-Free Grammars for page segmentation of structured documents. Two sets of text classification features are used to perform an initial classification of each zone of the page. Then, the page segmentation is obtained as the most likely hypothesis according to a grammar. This approach is compared to Conditional Random Fields and results show significant improvements in several cases. Furthermore, grammars provide a detailed segmentation that allowed a semantic evaluation which also validates this model.Work partially supported by the Spanish MEC under the STraDA research project (TIN2012-37475-C02-01), the MITTRAL (TIN2009- 14633-C03-01) project, the Spanish projects TIN2009-14633-C03-01/03 and 2010- CONES-00029, the FPU grant (AP2009-4363), by the Generalitat Valenciana under the grant Prometeo/2009/014, and through the EU 7th Framework Programme grant tranScriptorium (Ref: 600707)Álvaro Muñoz, F.; Cruz Fernández, F.; Sánchez Peiró, JA.; Ramos Terrades, O.; Benedí Ruiz, JM.

    El proyecto internacional Global Entrepreneurship Monitor (GEM) nació a finales del siglo XX, de la mano de Babson College y London Business School, para medir de manera homogénea el fenómeno emprendedor en diferentes territorios, facilitando el mayor conocimiento de los procesos de creación de empresas, su comparación y posibilidades de emitir recomendaciones para su impulso y mejora. GEM está organizado en forma de consorcio internacional y asociación sin ánimo de lucro (RED GEM España). GEM ofrece un sistema de información y análisis que permite evaluar la adecuación de las políticas y acciones emprendidas por los gobiernos, centrándose en los procesos de creación de empresas, con una metodología homologada a escala internacional que permite la comparación entre diferentes territorios y países. Una de las claves del reconocimiento internacional del proyecto GEM es la posibilidad de comparación interterritorial, a través de la medición de la actividad emprendedora total en cada territorio analizado. Esta medición y la posibilidad de comparación permiten observar el impacto de las políticas públicas en cada territorio, además de otras variables, sobre la creación de empresas a lo largo del tiempo. Los informes de carácter nacional, en algunos países, como es el caso de España, se complementan y detallan con informes de ámbito regional que permite decisiones más cercana a la diversidad territorial. La aplicación de una metodología común para todos los países y regiones asegura la comparación de los resultados de cada estudio territorial. El diseño de la investigación favorece la obtención de una serie de indicadores homogéneos para cada país o región participante, que garantizan la validez y el sentido de la comparación. Las fuentes de información que GEM emplea para la realización de los informes son tres: (1) una encuesta a la población adulta (de 18 a 64 años de edad) de cada país y territorio, para detectar las características específicas de los emprendedores y los condicionantes específicos de la creación de empresas; (2) un cuestionario dirigido a un panel de expertos, que permite obtener una opinión cualificada y diversa sobre el fenómeno emprendedor; y (3) un conjunto de variables secundarias, económicas y sociales, obtenidas de fuentes contrastadas a escala internacional. La información recabada a través de estas tres fuentes, que se completan y complementan, se trata y elabora como base para la realización de los distintos apartados que integran el informe.

    Purpose The monarchE trial showed that the addition of abemaciclib improves efficacy in patients with high-risk early breast cancer (EBC). We analyzed the long-term outcomes of a population similar to the monarchE trial to put into context the potential benefit of abemaciclib. Methods HR-positive/HER2-negative EBC patients eligible for the monarchE study were selected from 3 adjuvant clinical trials and a breast cancer registry. Patients with ≥ 4 positive axillary lymph nodes (N +) or 1–3 N + with tumor size ≥ 5 cm and/or histologic grade 3 and/or Ki67 ≥ 20%, who had undergone surgery with curative intent and had received anthracyclines ± taxanes and endocrine therapy in the neoadjuvant and /or adjuvant setting were included. We performed analysis of Invasive Disease-Free Survival (iDFS), Distant Disease-Free Survival (dDFS) and Overall Survival (OS) at 5 and 10 years, as well as yearly (up to 10) of Invasive Relapse Rate (IRR), Distant Relapse Rate (DRR) and Death Rate (DR). Results A total of 1,617 patients were analyzed from the GEICAM-9906 (312), GEICAM-2003–10 (210), and GEICAM-2006–10 (160) trials plus 935 from El Álamo IV. With a median follow-up of 10.1 years, the 5 and 10 years iDFS rates were 75.2% and 57.0%, respectively. The dDFS and OS rates at 5 years were 77.4% and 88.8% and the respective figures at 10 years were 59.7% and 70.9%. Conclusions This data points out the need for new therapies for those patients. A longer follow-up of the monarchE study to see the real final benefit with abemaciclib is warranted
