LUDOLITERACY Informe sobre la alfabetización mediática en el juego digital. Experiencias en Europa

El informe que a continuación presentamos recoge 18 experiencias, proyectos, actividades,investigaciones o políticas más significativas que se realizan en Europa relacionadas con la alfabetización mediática en el contexto de los videojuegos (ludoliteracy). La ludoliteracy tiene como finalidad potenciar las capacidades y competencias analíticas, reflexivas y creativas alrededor del juego digital. Se trata, en conjunto, de propuestas que permiten al ciudadano (joven o adulto, profesional o usuario) y a la sociedad en general ser más conscientes de nuestros propios placeres, tener capacidad crítica y competencia creativa en el campo específico de los juegos digitales.El objetivo final del informe es ofrecer recomendaciones en un campo socialmente controvertido y económicamente situado a la cabeza de las industrias culturales pero institucionalmente emplazado en los márgenes de las políticas educativas estatales y europeas.

La Fractura digital

La Brecha Digital. Según la OECD, en su 'Understanding Digital Divide' 2001, el término de Brecha Digital se refiere a las diferencias entre los individuos, hogares, empresas y áreas geográficas en los diferentes niveles socioeconómicos en relación con sus posibilidades de acceso a la información y a la comunicación (TIC) y su uso con internet para una gran variedad de actividades.

Alternative Energy Conversion Systems for a Micro Scale Wind Turbine

This Master's thesis deals with a Micro Scale Wind Wind Turbine application. The thesis consists of nine chapters. The first chapter is an introduction to the philosophy of a small scale wind turbine application. The second defines concepts, and lists the requirements. The third presents the whole application for an On-Grid , and for an Off-Grid arrangement, with main concentration on lighting, heating, and energy storage. The fourth deals with the Inverter's technology, which are used for the conversion of the produced power. The fifth chapter presents the available storage technology and it's possibilities. The sixth deals with the system, and the technological means used for the implementation. The seventh presents the PLC device, which was used as the controller for the management of the whole application. The eighth deals with the concept and the control application philosophy that the PLC involves. And the final chapter presents conclusions and ideas for further considerations.

Factors Affecting Consumer’s Illicit Purchase of Copyrighted Digital Work

Peer-to-Peer (P2P) technology has revolutionized file exchange activities besides enhancing processing power distribution. As such, this technology which is nowadays made freely available to all internet users also imposes a threat as it enables the illegal distribution of copyrighted digital work. P2P technology continuously evolves in a greater pace than copyright legislation, leading to compatibility gaps between the applicability of copyright law and the illicit file sharing and downloading. Such issues give high incentives to consumers to practise piracy using P2P systems with a low perception of risk towards prosecution, leading to substantial losses for copyright owners. This study focuses on developing insights for content owners on consumer behaviour towards piracy in Finland, where quantitative analyses are assessed using a data set based on a survey conducted by the Helsinki Institute for IT. The research approach investigates the significance of three fundamental areas in relation to evaluate consumer behaviour as: environmental-related factors, innovation-related factors and consumer-related. each of these are integrates concepts derived in previous theoretical models such as the technology acceptance model, theory of reasoned action, theory of planned behaviour, the issue-risk-judgement model and the Hunt & Vitell’s model.

Shout and Act: an Algorithm for Digital Objects Preservation Inspired from Rescue Robots

We adapt the Shout and Act algorithm to Digital Objects Preservation where agents explore file systems looking for digital objects to be preserved (victims). When they find something they “shout” so that agent mates can hear it. The louder the shout, the urgent or most important the finding is. Louder shouts can also refer to closeness. We perform several experiments to show that this system works very scalably, showing that heterogeneous teams of agents outperform homogeneous ones over a wide range of tasks complexity. The target at-risk documents are MS Office documents (including an RTF file) with Excel content or in Excel format. Thus, an interesting conclusion from the experiments is that fewer heterogeneous (varying skills) agents can equal the performance of many homogeneous (combined super-skilled) agents, implying significant performance increases with lower overall cost growth. Our results impact the design of Digital Objects Preservation teams: a properly designed combination of heterogeneous teams is cheaper and more scalable when confronted with uncertain maps of digital objects that need to be preserved. A cost pyramid is proposed for engineers to use for modeling the most effective agent combinations

Multímetro interfaceado de baixo custo para aquisição de dados

A digital multimeter (~U$ 240.00 on the national market) connected to a microcomputer by a RS-232 serial interface is proposed for data acquisition in equipment with analog output. Data are measured at the rate of 2 points per second and stored in text files by the software that accompanies the device, running in a Windows environment. The performance of the multimeter was verified by monitoring the transient signals generated in flow injection systems associated with fluorimetric, spectrophotometric and flame photometric detection. In addition, the performance of the proposed device was similar to that attained by employing an interface card with a 12-bit analog-to-digital converter for acquisition of the signals generated by a capillary electrophoresis equipment with oscillometric detection.

Creació d’un Dipòsit Digital d’Activitats Docents amb l’ús de les TIC a la Universitat de Vic

Avui en dia no es poden entendre els canvis socials sense pensar en les conseqüències derivades del nou paradigma digital de comunicació (Castells, 2003). Les Tecnologies de la Informació i la Comunicació (TIC) s’han convertit en eines d’ús quotidià que afecten a tots els àmbits de la vida, des de la gestió del sistema polític, la comunicació a les organitzacions i, també, les noves metodologies d’aprenentatge en les institucions educatives.
