El sirventès en la poesia catalana dels segles XIV-XV : un catàleg

The sirventes of the troubadour era has been broadly studied, but there are not overall explanations concerning theevolution of the sirventes genre in the Catalan-speaking lands of the fourteenth and fifteenth centuries. This paperpropounds a catalogue of sirventesos concerning its historical development, the troubadour models, rhetorical andgrammatical treatises, and genre assignment in rubrics. Our catalogue contains thirty-one Catalan sirventesos, includingtwenty-eight extant items and three items lost. In some cases the literary motifs of the sirventes cross boundaries in aprocess of poetic hybridization with other moral genres which borrow out themes, images and rhetorical strategies fromthe sirventes. In order to reflect this complexity, our catalogue also includes an annex with twenty-seven texts that are notproperly sirventesos but, due to their idiosyncrasy, can be placed in the periphery of the genre

Diversidad de poderes en África y resolución de conflictos

El conjunto de textos recogidos en este volumen son el resultado del seminario internacional “La Paz y la Palabra. Procesos de reconciliación posbélica en el África Subsahariana” celebrado los días 27 y 28 de noviembre de 2008 en Barcelona, coordinado científicamente por el Centro de Estudos Africanos del ISCTE de Lisboa y la red de estudios africanos ARDA/RIDA, con sede en Barcelona, y organizado por la Fundación CIDOB. Este encuentro significaba la segunda edición de un proyecto internacional iniciado en Lisboa en marzo de 2007 con un primer seminario que llevaba por título “Autoridades tradicionais: um universo em mudança”, y que fue coordinado por las mismas entidades

PairWise Neighbours database: overlaps and spacers among prokaryote genomes

<p>Abstract</p> <p>Background</p> <p>Although prokaryotes live in a variety of habitats and possess different metabolic and genomic complexity, they have several genomic architectural features in common. The overlapping genes are a common feature of the prokaryote genomes. The overlapping lengths tend to be short because as the overlaps become longer they have more risk of deleterious mutations. The spacers between genes tend to be short too because of the tendency to reduce the non coding DNA among prokaryotes. However they must be long enough to maintain essential regulatory signals such as the Shine-Dalgarno (SD) sequence, which is responsible of an efficient translation.</p> <p>Description</p> <p>PairWise Neighbours is an interactive and intuitive database used for retrieving information about the spacers and overlapping genes among bacterial and archaeal genomes. It contains 1,956,294 gene pairs from 678 fully sequenced prokaryote genomes and is freely available at the URL <url>http://genomes.urv.cat/pwneigh</url>. This database provides information about the overlaps and their conservation across species. Furthermore, it allows the wide analysis of the intergenic regions providing useful information such as the location and strength of the SD sequence.</p> <p>Conclusion</p> <p>There are experiments and bioinformatic analysis that rely on correct annotations of the initiation site. Therefore, a database that studies the overlaps and spacers among prokaryotes appears to be desirable. PairWise Neighbours database permits the reliability analysis of the overlapping structures and the study of the SD presence and location among the adjacent genes, which may help to check the annotation of the initiation sites.</p
