El entorno virtual de la Universitat d'Andorra: la visión del profesorado

En los últimos años las Universidades tradicionalmente presenciales han apostado por la incorporación de la tecnología en los procesos académicos, muestra de ello es la proliferación de campus virtuales que acogen entornos virtuales de aprendizaje. La Universitat d"Andorra utiliza un entorno virtual de aprendizaje desde hace 8 años. El presente trabajo analiza los usos del entorno por parte del profesorado con el objetivo de proponer mejoras que reviertan en la mejora del aprendizaje por parte de los estudiantes. Se ha seguido una metodología descriptiva que combina técnicas cuantitativas y técnicas cualitativas, se ha distribuido un cuestionario dirigido al profesorado y se han realizado dos grupos de discusión dirigidos a profesores y estudiantes respectivamente. Los resultados de este estudio han permitido identificar las necesidades de formación del profesorado de la Universitat d"Andorra y realizar un plan de acciones para la mejora del uso del entorno virtual que en el momento de hacer el estudio prácticamente se reducía a una herramienta de compartición de documentación.

Technology and research in a global Networked University Digital Library (NUDL)

Digital Libraries (DLs) are extremely complex information systems that support the creation, management, distribution, and preservation of complex information resources, while allowing effective and efficient interaction among the several societies that benefit from DL content and services. In this paper, we focus on our experience facing challenges of building, maintaining, and developing the Networked University Digital Library (www.nudl.org), an extension of the Networked Digital Library of Theses and Dissertations (www.ndltd.org). NUDL is a worldwide initiative that addresses making the intellectual property produced in universities more accessible, stimulating international collaboration across all disciplines. We detail technological aspects of our solutions and research activities carried out to provide powerful and enriched services for the communities served by this initiative.

El espacio virtual de intercambio de información sobre recursos humanos en Ciencia y Tecnología de América Latina y el Caribe Del CV Lattes al CvLAC

Se describen los principales problemas de los diferentes sistemas de información para la gestión de la ciencia y tecnología de los países de América Latina y el Caribe y se identifican los retos y las alternativas para promover un mayor intercambio entre países del continente. La creación de un espacio de intercambio de información de los recursos humanos que participan en los sistemas de ciencia y tecnología, a través de una metodología común denominada el CvLAC, se constituye en una respuesta a los problemas identificados. El CvLAC parte de la experiencia brasileña del CvLattes. Se describen los objetivos y resultados esperados del Proyecto del CvLAC, ejecutado con la participación de Brasil, Colombia, Cuba, Chile, México y Venezuela. Se describen los desarrollos y alternativas a partir de los datos existentes en los países participantes en el proyecto, iniciando con Colombia y Chile, destacándose las infinitas posibilidades que las nuevas tecnologías de información digital y los nuevos desarrollos, logrados en este campo, hacen posible en términos de intercambio de datos.

A model of multilingual digital library

This paper addresses the problem of multilingual digital libraries. The motivation for a such a digital library comes from the diversity of languages of the Internet users as well as the diversity of content authors, from e-book authors to writers of courseware. The basic definitions of such a system, the specifications of its functionality and the identification of the items it holds are discussed. The impact of multilinguism in each of the former aspects is presented. A case study of a multilingual digital library - in the Maxwell System in PUC-Rio - is described in the last sections. Its main characteristics are described and the current status of its digital library is shown.

Aspectos filosóficos do virtual e as obras simbólicas no ciberespaço

Discute os aspectos filosóficos do virtual e relaciona-os com o ciberespaço. Assim, o virtual é capaz de explicar um novo modelo de realização das formas simbólicas, ou seja, aquela tomada no pólo do virtual onde a conjunção e... e... constitui-se em aliança desenhando o conhecimento sob a forma de rede e explicando a desmaterialização das obras, contra a realidade tomada no pólo da "reificação", cujo paradigma é o da materialidade. A virtualização no ciberespaço potencializa a virtualidade da linguagem produzindo formas simbólicas que são, em essência, metamórficas. O virtual opera, ainda, a desterritorialização dos signos, portanto a desmaterialização das obras, produzindo uma complexidade na representação humana, em vez de uma substituição completa das obras.

The Brazilian electronic theses and dissertations digital library: providing open access for scholarly information

This paper describes a project led by the Instituto Brasileiro de Informações em Ciência e Tecnologia (Ibict), a government institution, to build a national digital library for electronic theses and dissertations - Bibliteca Digital de Teses e Dissertações (BDTD). The project has been a collaborative effort among Ibict, universities and other research centers in Brazil. The developers adopted a system architecture based on the Open Archives Initiative (OAI) in which universities and research centers act as data providers and Ibict as a service provider. A Brazilian metadata standard for electronic theses and dissertations was developed for the digital library. A toolkit including open source package was also developed by Ibict to be distributed to potential data providers. BDTD has been integrated with the international initiative: the Networked Digital Library of Thesis and Dissertation (NDLTD). Discussions in the paper address various issues related to project design, development and management as well as the role played by Ibict. Conclusions highlight some important lessons learned to date and challenges for the future in expanding the BDTD project.

Virtual screening and computational optimization for the discovery of covalent prolyl oligopeptidase inhibitors with activity in human cells.

Our docking program, Fitted, implemented in our computational platform, Forecaster, has been modified to carry out automated virtual screening of covalent inhibitors. With this modified version of the program, virtual screening and further docking-based optimization of a selected hit led to the identification of potential covalent reversible inhibitors of prolyl oligopeptidase activity. After visual inspection, a virtual hit molecule together with four analogues were selected for synthesis and made in one-five chemical steps. Biological evaluations on recombinant POP and FAPα enzymes, cell extracts, and living cells demonstrated high potency and selectivity for POP over FAPα and DPPIV. Three compounds even exhibited high nanomolar inhibitory activities in intact living human cells and acceptable metabolic stability. This small set of molecules also demonstrated that covalent binding and/or geometrical constraints to the ligand/protein complex may lead to an increase in bioactivity.

Matrizes da linguagem e a organização virtual do conhecimento

Os signos e as linguagens foram investigados para a organização virtual do conhecimento por meio dos mecanismos de busca. Fundamentou-se na teoria das matrizes da linguagem-pensamento, postuladas por Santaella (2005), na qual se perscrutou as linguagens sonora, visual e verbal. O objetivo da investigação foi estabelecer uma categorização dos mecanismos de busca a partir da correspondência dessas matrizes da linguagem com a indexação virtual e o modus análogo de busca. Os resultados da investigação indicam ser adequada a categorização dos mecanismos de busca sob o critério dos paradigmas semiótico da linguagem em três matrizes, dado o seu modo de ser e sua operacionalidade, sendo eles baseados em conteúdos sonoros, visuais e verbais. Sinteticamente, a sintaxe é a representação do sonoro, a forma é a representação do visível e o discurso é a representação do conhecimento verbal.
