El Seminario Permanente de Inform??tica del CEP de Zamora presenta un manual de inform??tica para formaci??n del profesorado y para que lo utilicen como material de apoyo en el aula. Consta de tres partes: sistema operativo de MS-DOS, procesador de textos y base de datos estos dos ??ltimos de Open Access. Se dan nociones generales de inform??tica para familiarizarse con el uso del ordenador y se ense??a el manejo de los paquetes inform??ticos antes mencionados.

Se presenta una experiencia de elaboración de materiales de Física y Química usando la hoja de cálculo de Open Access II aplicada a tercero de BUP y COU. Se analiza el contexto del centro en el que se desarrolla la experiencia y se procede a la presentación del proyecto, especificando los objetivos propuestos, las posibles aplicaciones didácticas de la hoja de cálculo, la metodología de trabajo en el aula y los conocimientos informáticos necesarios para utilizar el material elaborado. Se presentan los modelos sobre los que se trabaja: 1. Cinética química, 2. Equilibrio químico, 3. Valoración ácido-base, 4. Reacciones de precipitación, 5. Farmacocinética: dosificación de medicamentos, 6. Tiros, 7. Oscilador armónico lineal, 8. Composición de movimientos vibratorios armónicos, 9. Ondas. 10. Interferencias y pulsaciones. Para cada modelo se presenta una guía del profesor y un guión de trabajo para el alumno. El uso de estas aplicaciones acerca al alumno a las técnicas de modelización y simulación. Se adjuntan transparencias y diskettes de apoyo.

The XWS (eXtreme WindStorms) catalogue consists of storm tracks and model-generated maximum 3 s wind-gust footprints for 50 of the most extreme winter windstorms to hit Europe in the period 1979–2012. The catalogue is intended to be a valuable resource for both academia and industries such as (re)insurance, for example allowing users to characterise extreme European storms, and validate climate and catastrophe models. Several storm severity indices were investigated to find which could best represent a list of known high-loss (severe) storms. The best-performing index was Sft, which is a combination of storm area calculated from the storm footprint and maximum 925 hPa wind speed from the storm track. All the listed severe storms are included in the catalogue, and the remaining ones were selected using Sft. A comparison of the model footprint to station observations revealed that storms were generally well represented, although for some storms the highest gusts were underestimated. Possible reasons for this underestimation include the model failing to simulate strong enough pressure gradients and not representing convective gusts. A new recalibration method was developed to estimate the true distribution of gusts at each grid point and correct for this underestimation. The recalibration model allows for storm-to-storm variation which is essential given that different storms have different degrees of model bias. The catalogue is available at www.europeanwindstorms.org.

 Today, Digital Systems and Services for Technology Supported Learning and Education are recognized as the key drivers to transform the way that individuals, groups and organizations “learn” and the way to “assess learning” in 21st Century. These transformations influence: Objectives - moving from acquiring new “knowledge” to developing new and relevant “competences”; Methods – moving from “classroom” based teaching to “context-aware” personalized learning; and Assessment – moving from “life-long” degrees and certifications to “on-demand” and “in-context” accreditation of qualifications. Within this context, promoting Open Access to Formal and Informal Learning, is currently a key issue in the public discourse and the global dialogue on Education, including Massive Open Online Courses (MOOCs) and Flipped School Classrooms.

Journal impact factors have become an important criterion to judge the quality of scientific publications over the years, influencing the evaluation of institutions and individual researchers worldwide. However, they are also subject to a number of criticisms. Here we point out that the calculation of a journal’s impact factor is mainly based on the date of publication of its articles in print form, despite the fact that most journals now make their articles available online before that date. We analyze 61 neuroscience journals and show that delays between online and print publication of articles increased steadily over the last decade. Importantly, such a practice varies widely among journals, as some of them have no delays, while for others this period is longer than a year. Using a modified impact factor based on online rather than print publication dates, we demonstrate that online-to-print delays can artificially raise a journal’s impact factor, and that this inflation is greater for longer publication lags. We also show that correcting the effect of publication delay on impact factors changes journal rankings based on this metric. We thus suggest that indexing of articles in citation databases and calculation of citation metrics should be based on the date of an article’s online appearance, rather than on that of its publication in print.
