Llama la atención sobre las preocupaciones ambientales más urgentes y sugiere la manera de prevenir más daños. Explica los peligros de la contaminación y el calentamiento global,la destrucción del ozono y la destrucción de los ecosistemas. Los experimentos que propone están escritos con un lenguaje sencillo para mostrar cómo observar, recopilar información, llegar a conclusiones y ayudarles a desarrollar el pensamiento científico a los niños entre ocho y once años. Para poner de relieve lo que ya se está haciendo se describe un día en la vida de un glaciólogo, un especialista en residuos urbanos, una agricultora ecológica, una especialista en animales en peligro de extinción, que describen cómo su trabajo es mejorar la gestión del planeta.

Quiere llamar la atención sobre los acuciantes problemas medioambientales que sufren la Tierra y sus océanos, así como, sugerir formas de prevenir mayores daños. Explica cuáles son estas amenazas, desde la sobrepesca a los daños causados por las tormentas y la destrucción del hábitat. Pero también se destacan informes y trabajos de profesionales que proponen maneras de mejorar la gestión del planeta y protegerlo para el futuro. En la cub. : Blue Peter. .

The Water and Global Change (WATCH) project evaluation of the terrestrial water cycle involves using land surface models and general hydrological models to assess hydrologically important variables including evaporation, soil moisture, and runoff. Such models require meteorological forcing data, and this paper describes the creation of the WATCH Forcing Data for 1958–2001 based on the 40-yr ECMWF Re-Analysis (ERA-40) and for 1901–57 based on reordered reanalysis data. It also discusses and analyses modelindependent estimates of reference crop evaporation. Global average annual cumulative reference crop evaporation was selected as a widely adopted measure of potential evapotranspiration. It exhibits no significant trend from 1979 to 2001 although there are significant long-term increases in global average vapor pressure deficit and concurrent significant decreases in global average net radiation and wind speed. The near-constant global average of annual reference crop evaporation in the late twentieth century masks significant decreases in some regions (e.g., the Murray–Darling basin) with significant increases in others.

The WFDEI meteorological forcing data set has been generated using the same methodology as the widely used WATCH Forcing Data (WFD) by making use of the ERA-Interim reanalysis data. We discuss the specifics of how changes in the reanalysis and processing have led to improvement over the WFD. We attribute improvements in precipitation and wind speed to the latest reanalysis basis data and improved downward shortwave fluxes to the changes in the aerosol corrections. Covering 1979–2012, the WFDEI will allow more thorough comparisons of hydrological and Earth System model outputs with hydrologically and phenologically relevant satellite products than using the WFD.

This article responds to scholarship on Beckett’s television plays that regards them as positive interventions which encourage the viewer to reconsider the conventions of the medium, and that raise the cultural standards of television drama. In making claims about how the plays address and educate their viewers, critical approaches shift between conceptions of audience. This analysis of Beckett’s plays on British television reconsiders their aesthetic strategies, their relationship with television culture, and the dominant assumptions of critical writing about them by examining the parallel between conceptions of the audience and conceptions of the child in writing about television and Beckett’s television plays.

While watching TV, viewers use the remote control to turn the TV set on and off, change channel and volume, to adjust the image and audio settings, etc. Worldwide, research institutes collect information about audience measurement, which can also be used to provide personalization and recommendation services, among others. The interactive digital TV offers viewers the opportunity to interact with interactive applications associated with the broadcast program. Interactive TV infrastructure supports the capture of the user-TV interaction at fine-grained levels. In this paper we propose the capture of all the user interaction with a TV remote control-including short term and instant interactions: we argue that the corresponding captured information can be used to create content pervasively and automatically, and that this content can be used by a wide variety of services, such as audience measurement, personalization and recommendation services. The capture of fine grained data about instant and interval-based interactions also allows the underlying infrastructure to offer services at the same scale, such as annotation services and adaptative applications. We present the main modules of an infrastructure for TV-based services, along with a detailed example of a document used to record the user-remote control interaction. Our approach is evaluated by means of a proof-of-concept prototype which uses the Brazilian Digital TV System, the Ginga-NCL middleware.

The literature reports research efforts allowing the editing of interactive TV multimedia documents by end-users. In this article we propose complementary contributions relative to end-user generated interactive video, video tagging, and collaboration. In earlier work we proposed the watch-and-comment (WaC) paradigm as the seamless capture of an individual`s comments so that corresponding annotated interactive videos be automatically generated. As a proof of concept, we implemented a prototype application, the WACTOOL, that supports the capture of digital ink and voice comments over individual frames and segments of the video, producing a declarative document that specifies both: different media stream structure and synchronization. In this article, we extend the WaC paradigm in two ways. First, user-video interactions are associated with edit commands and digital ink operations. Second, focusing on collaboration and distribution issues, we employ annotations as simple containers for context information by using them as tags in order to organize, store and distribute information in a P2P-based multimedia capture platform. We highlight the design principles of the watch-and-comment paradigm, and demonstrate related results including the current version of the WACTOOL and its architecture. We also illustrate how an interactive video produced by the WACTOOL can be rendered in an interactive video environment, the Ginga-NCL player, and include results from a preliminary evaluation.

Some dosimetric properties of watch glasses were studied applying the thermoluminescence technique. The watch glass samples were powdered, and the selected grains were mixed with Teflon (TM). The mixture was pressed and sintered to produce pellets of watch glass-Teflon (TM) composites. The glow curves of the pellets show two peaks at 130 and 195 degrees C. Reproducibility of TL response was estimated to have a maximum coefficient of variation of 4.0%. The dose-response curve is sublinear between 0.5 and 20.0kGy. The calibration curve is linear between 1.0Gy and 1.0kGy. The minimum detection limits were also determined. The gamma radiation dose response and the thermal stability of the materials were studied with the purpose to establish the best conditions of watch glasses for use in gamma radiation dosimetry.

The text aims to show how Social Watch alternative site contributes to the construction of world citizenship to publish proposals for non-governmental organizations (NGOs), identified with groups excluded from traditional means of mass communication. The structure of the site is analyzed and studied in depth one of its publications, the Bulletin of August 2014, using some resources from the methodology of the framing and content analysis. The analysis shows that, in fact, the site is presented as place where civil society can express themselves and collect public power projects and proposals to increase the global citizenship.

In this paper we discuss the problem of how to discriminate moments of interest on videos or live broadcast shows. The primary contribution is a system which allows users to personalize their programs with previously created media stickers-pieces of content that may be temporarily attached to the original video. We present the system's architecture and implementation, which offer users operators to transparently annotate videos while watching them. We offered a soccer fan the opportunity to add stickers to the video while watching a live match: the user reported both enjoying and being comfortable using the stickers during the match-relevant results even though the experience was not fully representative.
