Estándares para e-learning adaptativo y accesible

Currently there are many standards that deal with accessibility issues regarding users’ models, learning scenarios, interaction preferences, devices capabilities, metadata for specifying the delivery of any resource to meet users’ needs, and software accessibility and usability. It is difficult to understand the existing relationships between these standards, as each one represents a different viewpoint and thus has its own sets of goals and scope. This paper gives an overview on existing standards addressing accessibility, usability and adaptation issues in e-learning, and discusses their application to cope with the objectives of the A2UN@ project, which focuses on attending the accessibility and adaptation needs for ALL in Higher Education

Ecological assembly rules in plant communities--approaches, patterns and prospects.

Understanding how communities of living organisms assemble has been a central question in ecology since the early days of the discipline. Disentangling the different processes involved in community assembly is not only interesting in itself but also crucial for an understanding of how communities will behave under future environmental scenarios. The traditional concept of assembly rules reflects the notion that species do not co-occur randomly but are restricted in their co-occurrence by interspecific competition. This concept can be redefined in a more general framework where the co-occurrence of species is a product of chance, historical patterns of speciation and migration, dispersal, abiotic environmental factors, and biotic interactions, with none of these processes being mutually exclusive. Here we present a survey and meta-analyses of 59 papers that compare observed patterns in plant communities with null models simulating random patterns of species assembly. According to the type of data under study and the different methods that are applied to detect community assembly, we distinguish four main types of approach in the published literature: species co-occurrence, niche limitation, guild proportionality and limiting similarity. Results from our meta-analyses suggest that non-random co-occurrence of plant species is not a widespread phenomenon. However, whether this finding reflects the individualistic nature of plant communities or is caused by methodological shortcomings associated with the studies considered cannot be discerned from the available metadata. We advocate that more thorough surveys be conducted using a set of standardized methods to test for the existence of assembly rules in data sets spanning larger biological and geographical scales than have been considered until now. We underpin this general advice with guidelines that should be considered in future assembly rules research. This will enable us to draw more accurate and general conclusions about the non-random aspect of assembly in plant communities.

Recursos web i metadades: informe del projecte

El projecte Recursos web i metadades, que ha comptat amb una ajuda econòmica de la Divisió V per a projectes de recerca, es plantejà amb l'objectiu principal de comprovar les dificultats d'aplicació del sistema de metadades DC a la descripció de les pàgines d'un lloc web universitari i l'efectivitat d'aquestes metadades tant per a la descripció de recursos web com per a la seva ulterior cerca i recuperació. Per al desenvolupament del projecte s'han adaptat i desenvolupat una sèrie d'eines de les quals també es vol comprovar l'eficàcia. En aquest informe s'explica el desenvolupament del projecte, el seu estat el novembre de 2001 i també les eines desenvolupades

La preservació digital

L'explosió de la informació digital en les col·leccions bibliotecàries d'aquesta dècada passada ens ha ofert molts beneficis, especialment en relació al seu accés, emmagatzematge i ús. No obstant això, queden tota una sèrie de qüestions referents a la preservació a llarg termini d'aquests materials que encara no tenen resposta. Aquest article explora alguns dels aspectes principals, com ara les pròpies dades que cal preservar; les amenaces derivades de l'obsolescència dels mitjans físics d'emmagatzematge, els formats, el programari i el maquinari; les tècniques proposadesmactualment per a la preservació a llarg termini; la importància de conservar també les metadades, i els tipus d'institucions que estan implicades -o que haurien d'estar-hi- en la cerca de les solucions necessàries.
