Amb l'aprovació del programa de Tampere el 1999 la Unió Europea (UE) va començar a articular una política d'immigració cap a l'exterior, sent prioritaris els països veïns d'Europa oriental en l'establiment de l'agenda en qüestions migratòries. El contingut d'aquesta agenda inclou normes aprovades bilateralment entre la Unió i els països veïns, normes que emanen de règims internacionals i fins i tot normes pròpies del patrimoni de la Unió. Aquest Working Paper analitza sintèticament l'agenda en matèria d'immigració entre la UE i els països veïns d'Europa oriental en funció del tipus de normes que es disposen a adoptar. Per això, s'han d'observar tres subsectors de la política d'immigració (immigració irregular, immigració regular i asil) per a cada un dels tres països de l'àrea amb els que la cooperació ha estat més intensa (Rússia, Ucraïna i Moldàvia). Prova d'això és l'entrada en vigor de sengles acords de readmissió i facilitació de visats entre la UE i aquests països. L'objectiu d'aquest article és elaborar un retrat matisat de l'agenda d'immigració més ambiciosa que la UE ha dissenyat cap a l'exterior.

Climate change has created the need for new strategies in conservation planning that account for the dynamics of factors threatening endangered species. Here we assessed climate change threat to the European otter, a flagship species for freshwater ecosystems, considering how current conservation areas will perform in preserving the species in a climatically changed future. We used an ensemble forecasting approach considering six modelling techniques applied to eleven subsets of otter occurrences across Europe. We performed a pseudo-independent and an internal evaluation of predictions. Future projections of species distribution were made considering the A2 and B2 scenarios for 2080 across three climate models: CCCMA-CGCM2, CSIRO-MK2 and HCCPR HAD-CM3. The current and the predicted otter distributions were used to identify priority areas for the conservation of the species, and overlapped to existing network of protected areas. Our projections show that climate change may profoundly reshuffle the otter's potential distribution in Europe, with important differences between the two scenarios we considered. Overall, the priority areas for conservation of the otter in Europe appear to be unevenly covered by the existing network of protected areas, with the current conservation efforts being insufficient in most cases. For a better conservation, the existing protected areas should be integrated within a more general conservation and management strategy incorporating climate change projections. Due to the important role that the otter plays for freshwater habitats, our study further highlights the potential sensitivity of freshwater habitats in Europe to climate change.

The primary goal of this paper is to discuss how the leading position of Brazil in South America could contribute to boost security cooperation between the European Union and Mercosur. Both parties share common foreign and security policy concerns, including immigration, terrorism and drug trafficking. Through its great influence on the regional security agenda, Brazil could seek closer bilateral cooperation with Europe in tackling these global challenges, acting at the same time as a representative of regional interests.

Las relaciones que América Latina pueda establecer con la Unión Europea tienen ,de hecho, carácter estratégico. Ello afecta tanto al acceso a los mercados y a la diversificación de los vínculos externos, políticos y económicos, como a los modelos y las visiones ideológicas que compiten en la economía política global. Hay que subrayar que en América Latina la Unión Europea sigue siendo una importante referencia como modelo social y político, en la medida que aún presente alguna diferencia respecto del “Consenso de Washington” de inspiración neoliberal que impregna el proyecto del ALCA,45 sus evidentes pretensiones hegemónicas, y el unilateralismo que en ocasiones preside la política estadounidense hacia la región, por ejemplo en lo referido al espinoso asunto de las drogas ilegales. En relación a este hecho, a título de ejemplo, cabe destacar las propuestas del Presidente de México, Vicente Fox, sobre la necesidad de ir más allá del ALCAN y constituir una “Comunidad de América del Norte” que aborde cuestiones como la libre circulación de trabajadores y una posible “política de cohesión”, y las referencias al “modelo europeo” presentes en las propuestas de Luis Inácio “Lula” da Silva, presidente electo de Brasil para la revitalización de Mercosur con un parlamento, una moneda y una política exterior común. Esta cuestión puede tener importantes implicaciones para las relaciones entre ambas regiones. Ante las dificultades que plantea la agenda del libre comercio, a nivel multilateral y bilateral, las iniciativas para fortalecer los procesos de integración regional, y en especial Mercosur, podrían convertirse en uno de los asuntos centrales de la cooperación de la Unión Europea y América Latina.

Immobile location-allocation (LA) problems is a type of LA problem that consists in determining the service each facility should offer in order to optimize some criterion (like the global demand), given the positions of the facilities and the customers. Due to the complexity of the problem, i.e. it is a combinatorial problem (where is the number of possible services and the number of facilities) with a non-convex search space with several sub-optimums, traditional methods cannot be applied directly to optimize this problem. Thus we proposed the use of clustering analysis to convert the initial problem into several smaller sub-problems. By this way, we presented and analyzed the suitability of some clustering methods to partition the commented LA problem. Then we explored the use of some metaheuristic techniques such as genetic algorithms, simulated annealing or cuckoo search in order to solve the sub-problems after the clustering analysis

El treball en primer lloc presenta una breu introducció del moviment esperantista, explicitant els vincles entre pacifisme i esperantisme, particularment en el cas català. En segon lloc, i a partir d’una enquesta a aquest subconjunt del moviment per la pau, l’estudi, d’una banda, compara les característiques d’aquest col·lectiu amb les de la societat catalana i amb la d’esperantistes d’altres països. D’altra banda, analitza el grup mateix i l’eventual evolució personal dels seus membres. L’estudi no sobreentén, com en enquestes anteriors en altres països, el concepte d’«esperantista» com el fet de ser membre d’una associació esperantista, sinó que estudia quina concepció en tenen els mateixos membres del col·lectiu i persones pròximes. Els resultats mostren algunes diferències notables entre els esperantistes catalans i la resta de la població catalana, particularment en relació amb el nivell d’estudis, les opinions polítiques i el lleure. Per altra banda, confirma els resultats obtinguts amb esperantistes d’altres països, malgrat algunes diferències sensibles, que potser podrien explicar-se per la minorització nacional i lingüística dels catalans.

Pseudomonas fluorescens strain CHA0 protects plants from various root diseases. Antibiotic metabolites synthesized by this strain play an important role in disease suppression; their production is mediated by the global activator gene gacA. Here we show by complementation that the gacA gene is also essential for the expression of two extracellular enzymes in P. fluorescens CHA0: phospholipase C and a 47-kDa metalloprotease. In contrast, the production of another exoenzyme, lipase, is not regulated by the gacA gene. Protease, phospholipase and antibiotics of P. fluorescens are all known to be optimally produced at the end of exponential growth; thus, the gacA gene appears to be a general stationary-phase regulator.

International conservation organisations have identified priority areas for biodiversity conservation. These global-scale prioritisations affect the distribution of funds for conservation interventions. As each organisation has a different focus, each prioritisation scheme is determined by different decision criteria and the resultant priority areas vary considerably. However, little is known about how the priority areas will respond to the impacts of climate change. In this paper, we examined the robustness of eight global-scale prioritisations to climate change under various climate predictions from seven global circulation models. We developed a novel metric of the climate stability for 803 ecoregions based on a recently introduced method to estimate the overlap of climate envelopes. The relationships between the decision criteria and the robustness of the global prioritisation schemes were statistically examined. We found that decision criteria related to level of endemism and landscape fragmentation were strongly correlated with areas predicted to be robust to a changing climate. Hence, policies that prioritise intact areas due to the likely cost efficiency, and assumptions related to the potential to mitigate the impacts of climate change, require further examination. Our findings will help determine where additional management is required to enable biodiversity to adapt to the impacts of climate change

Background: New ways of representing diffusion data emerged recently and achieved to create structural connectivitymaps in healthy brains (Hagmann P et al. (2008)). These maps have the capacity to study alterations over the entire brain at the connection and network level. This is of high interest in complex disconnection diseases like schizophrenia. In this Pathology where multiple lines of evidence suggest the association of the pathology with abnormalities in neural circuitry and impaired structural connectivity, the diffusion imaging has been widely applied. Despite the large findings, most of the research using the diffusion just uses some scalar map derived from diffusion to show that some markers of white matter integrity are diminished in several areas of the brain (Kyriakopoulos M et al (2008)). Thanks to the structural connectionmatrix constructed by the whole brain tractography, we report in this work the network connectivity alterations in the schizophrenic patients. Methods: We investigated 13 schizophrenic patients as assessed by the DIGS (Diagnostic Interview for genetic studies, DSM IV criteria) and 13 healthy controls. We have got from each volunteer a DT-MRI as well as Qball imaging dataset and a high resolution anatomic T1 performed during the same session; with a 3 T clinical MRI scanner. The controls were matched on age, gender, handedness, and parental social economic-status. For all the subjects, a low resolution connection matrix is obtained by dividing the cortex into 66 gyral based ROIs. A higher resolution matrix is constructed using 250 ROIs as described in Hagmann P et al. (2008). These ROIs are respectively used jointly with the diffusion tractography to construct the high and low resolution densities connection matrices for each subject. In a first step the matrices of the groups are compared in term of connectivity, and not in term of density to check if the pathological group shows a loss of global connectivity. In this context the density connection matrices were binarized. As some local connectivity changes were also suspected, especially in frontal and temporal areas, we have also looked for the areas where the connectivity showed significant changes. Results: The statistical analysis revealed a significant loss of global connectivity in the schizophrenic's brains at level 5%. Furthermore, by constructing specific statistics which represent local connectivity within the anatomical regions (66 ROIs) using the data obtained by the finest resolution (250 ROIs) to improve the robustness, we found the regions that cause this significant loss of connectivity. The significance is observed after multiple testing corrections by the False Discovery Rate. Discussion: The detected regions are almost the same as those reported in the literature as the involved regions in schizophrenia. Most of the connectivity decreases are noted in both hemispheres in the fronto-frontal and temporo-temporal regions as well as some temporal ROIs with their adjacent ROIs in parietal and occipital lobes.

We present a new approach for analyzing the turnover rates of Cretaceous radiolarians recorded in pelagic sequences of western Tethys, The analysis of major extinction-radiation events and the fluctuation of diversity are compared with major paleoceanographic events and variation of diversity in dinoflagellates, calcareous nannoplankton and ammonites. There is an extraordinary correlation between biotic changes and sea level changes, temperatures, O, C and Sr isotopes, phosphorus accumulation rates and anoxic episodes. This reveals a predominantly abiotic control on the evolution of radiolarians. The rate of turnover and the diversity through time of two major orders of radiolarians (nassellarians and spumellarians) exhibits (1) the quasi-parallelism of their diversity curves, excluding a direct competition between them, (2) greater resistance of spumellarians to extinction during the early stage of extinction intervals and (3) a stronger post-extinction recovery of nassellarians. Evolutionary rates of radiolarians can be a good means of monitoring global environmental changes and allowing us to understand more clearly the relationship between plankton evolution, climate and pale oceanographic processes.
