Els formats digitals codifiquen i estructuren en llenguatge binari informació de morfologia variada. Cada format, però, està dissenyat per a un propòsit específic i, per tant, és vital conèixer-ne les propietats tècniques. La tria d’un format inadequat o la gestió deficient de les metadades poden comportar pèrdues irreversibles d’informació. Sobre aquesta premissa, l’article presenta la gestió dels formats digitals com una competència essencial dels professionals de la informació. Aquesta habilitat implica, entre altres tasques, determinar quin format és adient per a cada escenari d’ús, i prendre decisions ben fonamentades quant a les metadades, la nomenclatura dels fitxers i l’estructura de les col·leccions digitals., Item: revista de biblioteconomia i documentació, 2023: Núm.:74

Pedimos a una inteligencia artificial que escriba un poema como si fuera Lorca. El resultado muestra limitaciones por ahora insalvables; entre ellas, la tendencia a falsear lo que no sabe. ¿Qué harán en el futuro?

Some companies have begun to restrict the use of e-mail with the conviction that the information overload it causes undermines labor productivity. But the problem is not the tool, but the interruptions caused by excessive exchange of messages, often with irrelevant information. Therefore, the real solution is to establish appropriate management strategies and avoid excessive communication. Some initiatives are committed to moving the internal communication to social media, although it tends to fragment the information required to complete tasks.

Data mining is the process of analyzing large data sets to discover behaviour patterns and predict future actions. Data mining has many useful applications, but also has an exploratory approach that makes questionable the validity of certain deductions. Using personal information for predictive purposes has a direct impact on the lives of people and therefore requires acting in a framework of liability. A code of ethics is necessary.

This paper describes content syndication and its applications for libraries, information centres and publishers, and highlights it as a new opportunity considering the scant developments in this field. Further, it explains how syndication, as applied to Temaria, a portal of Spanish journals on library and information science, makes it easier to track an author or to keep up–to–date on specific subjects, amongst other possibilities.

Distributing news summaries by means of content syndication significantly improved access to current information, but has had only moderate acceptance despite optimistic predictions. Inadequate attention to good practice by many content producers have limited the usefulness of content syndication. In order for this redistribution method to become a truly beneficial tool, producers must develop best practice.

Documental needs of local televisions are presented, with special emphasis on audiovisual informative material, since it constitutes the programming block which demands more material to cover informative requirements, although other types of documentation are considered. Recommendations on treatment, management and use of created documentation are provided. Features of the documentary process are described, considering the peculiarities of local television as for economic, technical and human resources opposite to other models of television.

[spa] El impulso del emprendimiento obliga a mejorar la capacitación de los estudiantes para promover actitudes innovadoras. Así, es esencial que los futuros profesionales aprendan a abordar los elevator pitch. El objetivo de la presente innovación docente es implementar talleres de elevator pitch en 5 facultades de la Universitat de Barcelona, así como pilotar una rúbrica transversal que evalúe los aspectos formales de cualquier elevator pitch con independencia de la disciplina o el sector profesional.

Social platforms for image storing and sharing have proved useful both as online showcases and as long-term personal archives. Particularly on Flickr, the most community-oriented photo repository on the web, users seek to make their photographs publicly available, giving them titles and descriptions and including them in thematic groups to make them easier to find. From a sample of 400 images posted by as many individual users, this small-scale study explores the efforts made by users to facilitate the retrieval and discovery of the personal photographs they post on Flickr. Las plataformas sociales para almacenar y compartir imágenes han demostrado su utilidad como escaparate digital y como archivo duradero. Particularmente en Flickr, el depósito de fotografías más orientado a la creación de comunidad, los usuarios se preocupan por poner sus imágenes a disposición pública: las titulan, las describen y las agregan a grupos temáticos para hacerlas más fáciles de encontrar. A partir de una muestra de 400 instantáneas, que corresponden a otros tantos usuarios individuales, este estudio a pequeña escala explora los esfuerzos que las personas dedican a facilitar la recuperación y el descubrimiento de las fotografías personales que publican en Flickr.

Este trabajo caracteriza el aprendizaje servicio (ApS) desde la perspectiva de la psicología positiva y, por tanto, como una metodología de aprendizaje que incide en la formación emocional y de valores de los estudiantes, e impulsa su motivación académica. El Grupo de innovación docente consolidado en Comunicación y Medios Audiovisuales (In-COMAV) promueve en el grado de Comunicación Audiovisual (CAV) de la Universitat de Barcelona este tipo de aprendizaje desde el curso 2016-2017. Se presentan aquí los criterios establecidos para la aceptación de proyectos ApS, las ventajas formativas en CAV y los resultados que la iniciativa ha tenido sobre el alumnado.

The emergence of social platforms for image storing and sharing has brought new ways to organize and disseminate personal photograph collections. In these online spaces, people can share their images with their contacts or with the public, and they can use the site as an online showcase of their creations. Therefore, these platforms seem to have a great potential as a long-term personal archive. Flickr, one of the earliest examples of social computing, is the most community-oriented photo repository. Users of this platform don't just group their images according to their personal meaning; they now think in a broader context and are concerned about making their photographs available to the whole community: they title them, describe them and include them in pools to make them easier to find. From a sample of 200 images, corresponding to as many individual users, this small-scale study explains the efforts made by users to facilitate the retrieval and discovery of the personal photographs they post on Flickr.

Information overabundance makes information more harmful than beneficial because we can not handle the myriad impulses we receive every day. Exposure to a wealth of information to the extent of overload reduces our ability to solve problems and make good decisions.

Consumers are becoming increasingly skeptical of marketing promises: more and more people avoid buying anything unless they first read others' opinion on the Internet. Advertising makeup is no longer effective: consumers no longer listen to the company, but they listen to each other. Companies are affected by this situation, so they have to rethink their communication strategy to control their online reputation.

In everyday life, increasingly digital, people are unwittingly feeding many databases with data about their habits. From the digital trail they leave everywhere, data mining can be used to uncover behavior patterns and anticipate their actions. This think piece discusses the consequences of this controversial process, which is capable of predicting and manipulating people's behavior.

Information processing has been a critical element in all forms of social development but the current conditions of life, sharply technological, mean that the fact of creating, processing and transmitting information is today a source of productivity and power. Nowadays, people work in an environment of information competition: much of the information circulating is delivered in order to gain visibility. But attention is a precious and scarce commodity because everyone directs their attention according to personal priorities.
