Les llicències de Creative Commons són una alternativa a la gestió tradicional dels drets d'autor que s'ha estès ràpidament gràcies a Internet en els seus cinc anys d'existència. L'aparició d'aquesta nova eina legal ha obert un debat sobre els models de difusió de qualsevol contingut i, en definitiva, del coneixement que ha obligat a replantejaments no tan sols entre els autors i els creadors sinó també entre institucions i administracions. En aquest llibre es presenta el model que proposa Creative Commons per facilitar la difusió i l'accés als continguts de qualsevol persona, tot respectant-ne els drets d'autor.

AbstractBACKGROUND: Scientists have been trying to understand the molecular mechanisms of diseases to design preventive and therapeutic strategies for a long time. For some diseases, it has become evident that it is not enough to obtain a catalogue of the disease-related genes but to uncover how disruptions of molecular networks in the cell give rise to disease phenotypes. Moreover, with the unprecedented wealth of information available, even obtaining such catalogue is extremely difficult.PRINCIPAL FINDINGS: We developed a comprehensive gene-disease association database by integrating associations from several sources that cover different biomedical aspects of diseases. In particular, we focus on the current knowledge of human genetic diseases including mendelian, complex and environmental diseases. To assess the concept of modularity of human diseases, we performed a systematic study of the emergent properties of human gene-disease networks by means of network topology and functional annotation analysis. The results indicate a highly shared genetic origin of human diseases and show that for most diseases, including mendelian, complex and environmental diseases, functional modules exist. Moreover, a core set of biological pathways is found to be associated with most human diseases. We obtained similar results when studying clusters of diseases, suggesting that related diseases might arise due to dysfunction of common biological processes in the cell.CONCLUSIONS: For the first time, we include mendelian, complex and environmental diseases in an integrated gene-disease association database and show that the concept of modularity applies for all of them. We furthermore provide a functional analysis of disease-related modules providing important new biological insights, which might not be discovered when considering each of the gene-disease association repositories independently. Hence, we present a suitable framework for the study of how genetic and environmental factors, such as drugs, contribute to diseases.AVAILABILITY: The gene-disease networks used in this study and part of the analysis are available at http://ibi.imim.es/DisGeNET/DisGeNETweb.html#Download

La estadística aplicada a la geografía ha experimentado un avance espectacular en las últimas dos décadas introduciéndose el espacio como eje fundamental del análisis. Este avance se ha visto acompañado por un rápido desarrollo de aplicaciones estadísticas integradas en los sistemas de información geográfica, constituyéndose de esta forma en un conjunto de herramientas imprescindibles en la planificación territorial. Por otro lado, en España, el incremento de población inmigrada en un corto intervalo de tiempo ha hecho necesario analizar su distribución espacial en las áreas urbanas. Los índices de autocorrelación espacial, tanto global como local, y su representación cartográfica constituyen una técnica adecuada para la detección de clusters y patrones espaciales y abre la posibilidad de plantear diferentes modelos econométricos. A partir del caso de la ciudad de Barcelona se aplican las técnicas descritas y se observan los diferentes comportamientos según el grupo de población estudiado.

Generalitzem el concepte de clúster de punts d'una superfície a clúster de seccions d'una família de superfícies per passar al cas relatiu, és a dir, a clústers de B-punts d'una B-superfície. Llavors definim, amb una propietat universal, la família universal de clusters de 2-seccions d'una família de superfícies, que, en cas que existir, és un esquema que parametritza tots els clústers de 2-seccions d'una famíla de superfícies. Demostrem la seva existencia sota certes hipotesis i trobem que es pot construir en termes de blowups a partir del producte de la família universal de seccions de la fmília de superficies per si mateixa. Al final del treball hi ha tres exemples que mostren part de la teoria estudiada.

In our capacity as creative artists, researchers and fine arts professors, most part of our activity focuses on the relationships between people and creativity, technology, and resources, and, most frequently, what we aim to offer are new enjoyable and subversive ways of interacting with these three fields. As art teachers, we ask 'why and how' to teach dynamic bearing in mind that digital technology will undoubtedly impact on contemporary art practice.

Over the past two decades, several fungal outbreaks have occurred, including the high-profile 'Vancouver Island' and 'Pacific Northwest' outbreaks, caused by Cryptococcus gattii, which has affected hundreds of otherwise healthy humans and animals. Over the same time period, C. gattii was the cause of several additional case clusters at localities outside of the tropical and subtropical climate zones where the species normally occurs. In every case, the causative agent belongs to a previously rare genotype of C. gattii called AFLP6/VGII, but the origin of the outbreak clades remains enigmatic. Here we used phylogenetic and recombination analyses, based on AFLP and multiple MLST datasets, and coalescence gene genealogy to demonstrate that these outbreaks have arisen from a highly-recombining C. gattii population in the native rainforest of Northern Brazil. Thus the modern virulent C. gattii AFLP6/VGII outbreak lineages derived from mating events in South America and then dispersed to temperate regions where they cause serious infections in humans and animals.

S'han estudiant les funcions neuropsicològiques en una mostra de 96 pacients amb malaltia de Parkinson (MP) i 42 controls aparellats per gènere, edat, escolaritat i intel.ligència verbal. Els resultats indiquen que els pacients afectats per MP, com a grup, presenten alteracions en les funcions visuoespacials, en la memòria i en les funcions frontals, però que aquests dèficits no estan sempre presents en tots els pacients. L'anàlisi de clusters realitzat ens mostra que les alteracions neuropsicològiques presents en la MP estan distribuides en subgrups. En un dels grups es va observar la presència d'afectació cognitiva generalitzada, mentre que el segon subgrup va mostrar absència de dèficits cognitius i, finalment, el darrer subgrup presentava alteracions específiques en les funcions visuoespacials i frontals. La puntuació verbal mostrava el mateix patró de deteriorament que les funcions frontals i es va trobar una diferència significativa entre els pacients i el grup control en aquesta funció. La presencia de depressió estava present en un 50% dels pacients i estava fortament relacionada amb els dèficits frontals. Els resultats d'aquest estudi mostren la importància d'avaluar les funcions neuropsicobiològiques i del llenguatge en els pacients afectats per MP, amb la finalitat de conèixer el patró de deteriorament, per tal d'afavorir-ne el funcionament i la qualitat de vida.

Using a database of 2,263 responses to R&D public calls in Catalonia, during the period 2007–2010, this paper proceeds to analyse the potential interaction of the territorial and policy dimensions with the propensity to apply for, and be awarded, a public R&D subsidy. Controlling for characteristics at the firm and project level, we estimate models using a twostep procedure. In the first step, our results suggest that large firms which export and which belong to high-tech manufactures are more likely to participate in a public R&D call. Furthermore, both urban location and past experience of such calls have a positive effect. Our territorial proxy of information spillovers shows a positive sign, but this is only significant at intra-industry level. Membership of one of the sectors prioritized by the Catalan government, perhaps surprisingly, does not have a significant impact. In the second step, our results show that cooperative projects, SMEs or old firms shows a positive effect on the probability of obtaining a public subsidy. Finally, the cluster policy does not show a clear relationship with the public R&D call, suggesting that cluster policies and R&D subsidies follow different goals. Our results are in line with previous results in the literature, but they highlight the unequal territorial distribution of the firms which apply and the fact that policymakers should interlink the decision criteria for their public call with other policies.

The analysis of the activity of neuronal cultures is considered to be a good proxy of the functional connectivity of in vivo neuronal tissues. Thus, the functional complex network inferred from activity patterns is a promising way to unravel the interplay between structure and functionality of neuronal systems. Here, we monitor the spontaneous self-sustained dynamics in neuronal cultures formed by interconnected aggregates of neurons (clusters). Dynamics is characterized by the fast activation of groups of clusters in sequences termed bursts. The analysis of the time delays between clusters' activations within the bursts allows the reconstruction of the directed functional connectivity of the network. We propose a method to statistically infer this connectivity and analyze the resulting properties of the associated complex networks. Surprisingly enough, in contrast to what has been reported for many biological networks, the clustered neuronal cultures present assortative mixing connectivity values, meaning that there is a preference for clusters to link to other clusters that share similar functional connectivity, as well as a rich-club core, which shapes a"connectivity backbone" in the network. These results point out that the grouping of neurons and the assortative connectivity between clusters are intrinsic survival mechanisms of the culture.

Aquest projecte tracta sobre quina evolució han tingut les empreses a la comarca d'Osona durant el període 2007-2012 agrupades per clústers. Així, pretén ser una continuació del "Pla d'Innovació d'Osona", efectuat el 2007, amb la col•laboració de diverses entitats de la comarca. Les agrupacions per clústers són realitzades a partir dels codis CNAE (Classificació Nacional d'Activitats Econòmiques). A través del processat d'aquestes dades, extretes de la base de dades SABI, s'ha observat quina tendència ha experimentat el nombre d'empreses i assalariats a la comarca i quines empreses són les que tenen uns ingressos d'explotació més elevats, arribant a la conclusió principal el fet que hi ha hagut un decrement generalitzat, tant d'assalariats com de nombre d'empreses i ingressos d'explotació a causa de la crisi econòmica iniciada el 2008.
