La Biblioteca de la UOC (UOC Library) ha ofert durant tres mesos (octubre-desembre 09), en fase de prova pilot, un servei de consulta i préstec de lectors de llibres electrònics (e-readers). Aquest nou desplegament s'ha desenvolupat en consonància amb l'aposta general de la Universitat en innovació en tecnologies aplicades a l'educació, i la voluntat de potenciar les col·leccions de llibres electrònics i l'ús dels dispositius de lectura de llibres electrònics com una extensió més de la tecnologia del Campus 5.0, en el suport a l'aprenentatge dels seus estudiants durant la seva formació a la Universitat. Aquest treball presenta en detall les especificacions de la prova pilot, a més de contenir una anàlisi i avaluació dels resultats obtinguts: punts forts i punts febles, relació dels aspectes a millorar i modificar, de cara a la consolidació final del servei.

Compositional data naturally arises from the scientific analysis of the chemicalcomposition of archaeological material such as ceramic and glass artefacts. Data of thistype can be explored using a variety of techniques, from standard multivariate methodssuch as principal components analysis and cluster analysis, to methods based upon theuse of log-ratios. The general aim is to identify groups of chemically similar artefactsthat could potentially be used to answer questions of provenance.This paper will demonstrate work in progress on the development of a documentedlibrary of methods, implemented using the statistical package R, for the analysis ofcompositional data. R is an open source package that makes available very powerfulstatistical facilities at no cost. We aim to show how, with the aid of statistical softwaresuch as R, traditional exploratory multivariate analysis can easily be used alongside, orin combination with, specialist techniques of compositional data analysis.The library has been developed from a core of basic R functionality, together withpurpose-written routines arising from our own research (for example that reported atCoDaWork'03). In addition, we have included other appropriate publicly availabletechniques and libraries that have been implemented in R by other authors. Availablefunctions range from standard multivariate techniques through to various approaches tolog-ratio analysis and zero replacement. We also discuss and demonstrate a smallselection of relatively new techniques that have hitherto been little-used inarchaeometric applications involving compositional data. The application of the libraryto the analysis of data arising in archaeometry will be demonstrated; results fromdifferent analyses will be compared; and the utility of the various methods discussed

The presentation will focus on the reasons for deploying an e-reader loan service at a virtual university library as a part of an e-learning support system to aid user mobility, concentration of documentary and electronic resources, and ICT skills acquisition, using the example of the UOC pilot project and its subsequent consolidation. E-reader devices at the UOC are an extension of the Virtual Campus. They are offered as a tool to aid user mobility, access to documentary and electronic resources, and development of information and IT skills. The e-reader loan service began as a pilot project in 2009 and was consolidated in 2010. The UOC Library piloted the e-reader loan service from October to December 2009. The pilot project was carried out with 15 devices and involved 37 loans. The project was extended into 2010 with the same number of devices and 218 loans (October 2010). In 2011 the e-reader loan service is to involve 190 devices, thus offering an improved service. The reasons for deploying an e-reader loan service at the UOC are the following: a) to offer library users access to the many kinds of learning materials available at the UOC through a single device that facilitates student study and learning; b) to enhance access to and use of the e-book collections subscribed to by the UOC Library; c) to align with UOC strategy on the development of learning materials in multiple formats, and promote e-devices as an extension of the UOC Virtual Campus, and d) to increase UOC Library visibility within and beyond the institution. The presentation will conclude with an analysis of the key issues to be taken into account at a university library: the e-reader market, the unclear business and license model for e-book contents, and the library's role in promoting new reading formats to increase use of e-collections.

Els objectius d'aquest informe són realitzar un estudi de la tècnica en la digitalització, l'emmagatzematge i l'accés a les tesis doctorals electròniques, per tal de fer una proposta d’organització al Consorci de Biblioteques Universitàries de Catalunya (CBUC). Actualment, tot i que existeixen diverses iniciatives a Europa, és als EUA on la digitalització de tesis doctorals s’ha desenvolupat més amb la creació de la Networked Digital Library for Theses and Dissertation (NDLTD), i ha estat qui ha definit els estàndards en aquest camp. En el següent informe es planteja i es recomana al CBUC l’adhesió institucional a l’NDLTD per poder gaudir de la seva experiència.

Study of the publication models and the means of accessing scientific literature in the current environment of digital communication and the web. The text introduces the concept of journal article as a well-defined and stable unit within the publishing world, and as a nucleus on which professional and scholarly communication has been based since its beginnings in the 17th century. The transformation of scientific communication that the digital world has enabled is analysed. Descriptions are provided of some of the practices undertaken by authors, research organisations, publishers and library-related institutions as a response to the new possibilities being unveiled for articles, both as products as well as for their creation and distribution processes. These transformations affect the very nature of articles as a minimal unit -both unique and stable- of scientific communication. The article concludes by noting that under varying documentary forms of publisher aggregation and bibliographic control -sometimes simultaneously and, even, apparently contradictory- there flourishes a more pluralistic type of scientific communication. This pluralism offers: more possibilities for communication among authors; fewer levels of intermediaries such as agents that intervene and provide added value to the products; greater availability for users both economically speaking and from the point of view of access; and greater interaction and wealth of contents, thanks to the new hypertext and multimedia possibilities.

Rapid growth in the availability and use of digital documents has prompted the development of instruments to handle them. A most important example of these instruments are digital identifiers, which provide a codification system that allows digital items, usually up to the level of a computer file, to be singled out and located. Digital identifiers make up standardized global systems applied to specific products or areas. They are part of the very many identifiers developed to handle large numbers of items and large amounts of information for transactional purposes, which often have a global span. Digital identifiers include the ubiquitous Global Trade Item Number (GTIN), a code that unequivocally identifies trade items all around the world. The GTIN can take on several configurations depending on its application. These include: EAN-13, EAN-8, EAN-14, and UCC-12. EAN-13 is the code used for retail products in order to facilitate trade at the point of sale; its widely known symbol or graphical form is the EAN/UPC-13 bar code...

El pasado mes de junio se celebró en Pittsburgh, EE.UU., el duodécimo simposio internacional sobre tesis electrónicas: Electronic Thesis and Dissertations Conference (ETD2009). Fue organizado por Networked Digital Library of Theses and Dissertations (NDLTD). La mayoría de los ponentes explicaron las experiencias de su propia universidad. Además, hubo expertos invitados entre los cuales se pueden destacar Stevan Harnad (Univ. Southampton), Karla Hahn (Association of Research Libraries) y Deanna Marcum (Library of Congress). Estos simposios pretenden promover la adopción, creación, uso, difusión y preservación de las tesis electrónicas. De hecho, el éxito ha sido tal, que algunas universidades ya prescinden de la copia en papel para el depósito y preservación del documento. Un caso reciente es el de la University of Albany cuya nueva política, anunciada durante el simposio, consiste en que a partir de setiembre del 2009 ya no requiere el depósito de una copia impresa de las tesis aprobadas en aquella universidad.

In its long and irregular transition, from traditional library to the electronic book we have seen combining and alternating the hybrid, electronic and most recently the digital libraries. All these concepts which are combining and are conditioning each other, are referring to methods of organization and use of an informational content (which exists or not in an informational structure).

This thesis deals the aspects of usability and design of a web from a user's point of view. The thesis will examine the elements comprised in the development of a web (the human and technological aspects and how the interact). It will explain in depth how to approach these issues correctly or incorrectly, how to avoid dealing with them incorrectly and how to find a happy medium, which is as they say where the virtue lays. The thesis is completed with the practical example of a creation of a web site (the MARK'S SCIENCE on-line library).
