A virtual exhibition of open source software for libraries

Frequently the choice of a library management program is conditioned by social, economic and/or political factors that result in the selection of a system that is not altogether suitable for the library���s needs, characteristics and functions. Open source software is quickly becoming a preferred solution, owing to the freedom to copy, modify and distribute it and the freedom from contracts, as well as for greater opportunities for interoperability with other applications. These new trends regarding open source software in libraries are also reflected in LIS studies, as evidenced by the different courses addressing automated programs, repositorymanagement, including the Linux/GNU operating system, among others. The combination of the needs of the centres and the new trends for open source software is the focus of a virtual laboratory for the use of open source software for library applications. It was the result of a project, whose aim was to make a useful contribution to the library community, that was carried out by a group of professors of the School of Library and Information Science of the University of Barcelona, together with a group of students, members of a Working Group on Open Source Software for Information Professionals, of the Professional Library Association of Catalonia.

Introducci��n de la semipresencialidad en el grado de Informaci��n y Documentaci��n: evolucionando con la sociedad

[spa] El curso 2011-2012 se inicia la introducci��n de la semipresencialidad en el grado de Informaci��n y Documentaci��n de la Facultad de Biblioteconom��a y Documentaci��n de la Universidad de Barcelona. Se ofrecen todas las asignaturas de primer curso en este formato para un grupo de 30 alumnos. La planificaci��n ha supuesto la determinaci��n de las condiciones y el grado de presencialidad, la creaci��n del material docente de las asignaturas en un campus virtual y el establecimiento de indicadores y mecanismos de seguimiento y evaluaci��n. Los primeros resultados apuntan diferencias importantes respecto al seguimiento de la titulaci��n en formato presencial.

Spatial weights : constructing weight-compatible exchange matrices from proximity matrices

Exchange matrices represent spatial weights as symmetric probability distributions on pairs of regions, whose margins yield regional weights, generally well-specified and known in most contexts. This contribution proposes a mechanism for constructing exchange matrices, derived from quite general symmetric proximity matrices, in such a way that the margin of the exchange matrix coincides with the regional weights. Exchange matrices generate in turn diffusive squared Euclidean dissimilarities, measuring spatial remoteness between pairs of regions. Unweighted and weighted spatial frameworks are reviewed and compared, regarding in particular their impact on permutation and normal tests of spatial autocorrelation. Applications include tests of spatial autocorrelation with diagonal weights, factorial visualization of the network of regions, multivariate generalizations of Moran's I, as well as "landscape clustering", aimed at creating regional aggregates both spatially contiguous and endowed with similar features.

Optimization of snowmaking in high mountains ski resort

Ski resorts are deploying more and more systems of artificial snow. These tools are necessary to ensure an important economic activity for the high alpine valleys. However, artificial snow raises important environmental issues that can be reduced by an optimization of its production. This paper presents a software prototype based on artificial intelligence to help ski resorts better manage their snowpack. It combines on one hand a General Neural Network for the analysis of the snow cover and the spatial prediction, with on the other hand a multiagent simulation of skiers for the analysis of the spatial impact of ski practice. The prototype has been tested on the ski resort of Verbier (Switzerland).

Tem��tica das disserta����es e teses em ci��ncia da informa����o no Programa de P��s-Gradua����o em Ci��ncias da Comunica����o da USP

Estudo de natureza descritiva cujo objetivo foi tra��ar um panorama tem��tico das disserta����es de mestrado e teses de doutorado apresentadas ao Programa de P��s-gradua����o em Ci��ncias da Comunica����o ��rea de concentra����o: Ci��ncia da Informa����o e Documenta����o da Escola de Comunica����es e Artes da Universidade de S��o Paulo, no per��odo de 1979 a 2002. O universo de estudo constituiu-se de 114 documentos (75 disserta����es de mestrado e 39 teses de doutorado). As vari��veis da produ����o analisada referiram-se �� distribui����o temporal, tem��ticas abordadas e sua rela����o com as linhas de pesquisa departamentais. As disserta����es/teses foram agrupadas nas categorias da Lista de Cabe��alho de Assunto adotada pelo Library and Information Science Abstracts (LISA). Observou-se que a produ����o discente da p��s-gradua����o manteve-se est��vel no per��odo, com tend��ncia a aumentar. Na an��lise tem��tica, as categorias 19.0 Other Fringe Subjects [Outros Assuntos Correlatos] e 12.0 Bibliographc Records [Registro Bibliogr��fico] foram as mais abordadas, detendo respectivamente, 22,81% e 15,54% da produ����o. Foram identificados como temas de maior interesse para a elabora����o dos trabalhos: a����o cultural, sistemas e linguagens de indexa����o, materiais em C&T e medicina, bibliotecas p��blicas e meios de comunica����o de massa. Contatou-se que as tem��ticas abordadas na produ����o refletem as caracter��sticas da ��rea de concentra����o e das linhas de pesquisa.

Informa����o para neg��cios: aspectos da literatura cient��fica nacional em revistas da ��rea de ci��ncia da informa����o

Realiza an��lise da produ����o brasileira de artigos cient��ficos da ��rea de ci��ncia da informa����o, a partir 126 artigos do per��odo de 1972 a 2006 que integraram a Base Brasileira sobre Informa����o para Neg��cios (Brapin). Caracteriza a produ����o quanto aos aspectos enfoques e tend��ncias de conte��do, autoria e freq����ncia por per��odo de publica����es, padronizando os 342 termos descritores de acordo com o tesauro da American Society for Information Science and Technology (Asis). Fundamenta a an��lise de conte��do em categorias representativas das principais tem��ticas do conjunto de textos sobre informa����o para neg��cios, constatando que, das 26 revistas da ��rea de biblioteconomia e ci��ncia da informa����o (BCI) presentes na base Brapin, apenas 13 publicaram artigos cient��ficos sobre o tema, destacando-se o ano de 1997 como o de maior produ����o. Do conjunto denominado informa����o para neg��cios, destaca-se a tem��tica informa����o tecnol��gica, com 45% dos artigos, e em rela����o ao tipo de autoria, predomina o individual.

Evolu����o te��rico-metodol��gica dos estudos de comportamento informacional de usu��rios

Este artigo visa a contribuir para o conhecimento mais aprofundado sobre estudos de comportamento informacional de usu��rios com base em como s��o tratados na literatura da ci��ncia da informa����o nas ��ltimas seis d��cadas. Para tanto, a an��lise se fundamenta nas revis��es publicadas no peri��dico Annual Review of Information Science and Technology (Arist) e em outros trabalhos que complementam o tema abordado, mostrando sua evolu����o te��rica e metodol��gica. Uma diferen��a crucial est�� relacionada �� mudan��a conceitual observada, a qual denota a amplia����o da vis��o epistemol��gica dos estudos. Tal mudan��a referese, especialmente, �� nova terminologia adotada, que passa de "estudos de usu��rios" ou "necessidades e uso de informa����o" para "comportamento informacional de usu��rios". Trata-se, contudo, n��o somente de altera����o terminol��gica, mas, sobretudo, de mudan��a paradigm��tica, resultado de transforma����es no modo como o t��pico �� definido e abordado, e na forma como �� investigado.

Rockfall detection from LIDAR point clouds: A clustering approach using R

The analysis of rockfall characteristics and spatial distribution is fundamental to understand and model the main factors that predispose to failure. In our study we analysed LiDAR point clouds aiming to: (1) detect and characterise single rockfalls; (2) investigate their spatial distribution. To this end, different cluster algorithms were applied: 1a) Nearest Neighbour Clutter Removal (NNCR) in combination with the Expectation?Maximization (EM) in order to separate feature points from clutter; 1b) a density based algorithm (DBSCAN) was applied to isolate the single clusters (i.e. the rockfall events); 2) finally we computed the Ripley's K-function to investigate the global spatial pattern of the extracted rockfalls. The method allowed proper identification and characterization of more than 600 rockfalls occurred on a cliff located in Puigcercos (Catalonia, Spain) during a time span of six months. The spatial distribution of these events proved that rockfall were clustered distributed at a welldefined distance-range. Computations were carried out using R free software for statistical computing and graphics. The understanding of the spatial distribution of precursory rockfalls may shed light on the forecasting of future failures.
