Sistema multimodal para la planificación de viajes en transportes públicos de código abierto y basado en estándares 'de facto' = A multimodal journey planner based on open source software and 'de facto' standards

Este artículo muestra cómo con bajo coste y riesgo se puede desarrollar un sistema de planificación de viaje multimodal, basado en un enfoque de código abierto y estándares ‘de facto’. Se ha desarrollado completamente una solución de código abierto para un sistema de información de transporte público puerta a puerta basado en estándares ‘de facto’. El cálculo de rutas se realiza mediante Graphserver, mientras que la cartografía se basa en OpenStreetMap. También se ha demostrado cómo exportar una base de datos real de horarios de transporte público como la del operador ETM (Empresa de Transporte Metropolitano de València) a la especificación de Google Transit, para permitir el cálculo de rutas, tanto desde nuestro prototipo como desde Google Transit

Adaptive integral assessment package for the A2UN@ project

This paper presents a first approach of Evaluation Engine Architecture (EEA) as proposal to support adaptive integral assessment, in the context of a virtual learning environment. The goal of our research is design an evaluation engine tool to assist in the whole assessment process within the A2UN@ project, linking that tool with the other key elements of a learning design (learning task, learning resources and learning support). The teachers would define the relation between knowledge, competencies, activities, resources and type of assessment. Providing this relation is possible obtain more accurate estimations of student's knowledge for adaptive evaluations and future recommendations. The process is supported by usage of educational standards and specifications and for an integral user modelling

Selecting Scientific Papers for Publication via Citation Auctions

The scientific community has been suffering from peer review for decades. This process (also called refereeing) subjects an author's scientific work or ideas to the scrutiny of one or more experts in the field. Publishers use it to select and screen manuscript submissions, and funding agencies use it to award research funds. The goal is to get authors to meet their discipline's standards and thus achieve scientific objectivity. Publications and awards that haven't undergone peer review are often regarded with suspicion by scholars and professionals in many fields. However, peer review, although universally used, has many drawbacks. We propose replacing peer review with an auction-based approach: the better the submitted paper, the more scientific currency the author likely bid to have it published. If the bid correctly reflects the paper's quality, the author is rewarded in this new scientific currency; otherwise, the author loses this currency. We argue that citations are an appropriate currency for all scientists. We believe that citation auctions encourage scientists to better control their submissions' quality. It also inspire them to prepare more exciting talks for accepted papers and to invite discussion of their results at congresses and conferences and among their colleagues. In the long run, citation auctions could have the power to greatly improve scientific research
