Sistema per protegir la privadesa dels usuaris dels motors de cerca d'Internet

Actualment seria impensable la existència d'una xarxa d'informació com Internet sense la existència dels motors de cerca. Gràcies a ells, qualsevol usuari tenim al nostre abast la possibilitat d'obtenir informació sobre qualsevol tema només enviant una consulta des dels nostres ordinadors i rebent una resposta en qüestió de segons. Entre els usuaris dels cercadors d'Internet és molt habitual que les consultes facin referència a la empresa on treballem, la ciutat on vivim, els llocs que visitem, o inclús sobre problemes que tenim o malalties que patim amb l'objectiu de trobar opinions, consells o solucions. En resum, els usuaris, a través de les nostres consultes, proporcionem a diari als motors de cerca informació sobre nosaltres mateixos i sobre la nostra identitat que, juntament amb la adreça IP de la màquina des d'on fem les nostres consultes, ens fa perdre l'anonimat dins dels seus sistemes. Sobre aquesta problemàtica és del que tracta el present Projecte de Final de Carrera. En ell s'ha implementat una solució de la proposta especificada per Alexandre Viejo i Jordi Castellà-Roca en la seva publicació "Using social networks to disort users' profiles generated by web search engines", en la qual es documenten una sèrie de protocols de seguretat i d'algorismes de protecció i distribució que garanteixen la privacitat de la identitat dels usuaris dins dels motors de cerca aprofitant per aquest fi la relació existent entre aquests usuaris a través de les xarxes socials.

When the mummy is digital : preservation and dissemination

Most educational institutions include nowadays a digital repository as part of their development and positioning strategy. The main goals of a digital repository are preservation and dissemination, which are some how contradictory, especially if the repository follows an open approach, as it is designed, built and managed from an institutional perspective, although it is intended to be used by teachers and learners. This fact may lead to a low level of usage, as final users are not able to integrate the learning object repository into their learning process. In this paper we will discuss how to promote open educational resources by connecting open repositories with open social networks, bridging the gap between resources and final users (teachers and learners).

The role of population movement in the epidemiology and control of schistosomiasis in Brazil: a preliminary typology of population movement

This paper examines recent developments in migration studies. It reviews literature related to the potential role of internal population movement in the occurrence of schistosomiasis in Brazil and modifies Prothero's typology of population movement for use in Brazil. This modified classification system may contribute to a better understanding of schistosome transmission as well as improved research and control programs. The results of this study indicate that population movement in Brazil primarily involves economically-motivated rural-urban and interregional movement. However, several movement patterns have become increasingly important in recent years as a result of changing socioeconomic and urbanisation dynamics. These patterns include urban-urban, intracity and urban-rural movement as well as the movement of environmental refugees and tourists. Little is known about the epidemiological significance of these patterns. This paper also highlights the role of social networks in the decision to migrate and to settle. Prothero's classic population movement typology categorises movement as either one-way migrations or circulations and examines them along spatial and temporal scales. However, the typology must be modified as epidemiological information about new patterns becomes available. This paper identifies areas that require further research and offers recommendations that can improve the measurement and spatial analysis of the relationship between population movement and schistosomiasis.

Genetic clusters and sex-biased gene flow in a unicolonial Formica ant.

BACKGROUND: Animal societies are diverse, ranging from small family-based groups to extraordinarily large social networks in which many unrelated individuals interact. At the extreme of this continuum, some ant species form unicolonial populations in which workers and queens can move among multiple interconnected nests without eliciting aggression. Although unicoloniality has been mostly studied in invasive ants, it also occurs in some native non-invasive species. Unicoloniality is commonly associated with very high queen number, which may result in levels of relatedness among nestmates being so low as to raise the question of the maintenance of altruism by kin selection in such systems. However, the actual relatedness among cooperating individuals critically depends on effective dispersal and the ensuing pattern of genetic structuring. In order to better understand the evolution of unicoloniality in native non-invasive ants, we investigated the fine-scale population genetic structure and gene flow in three unicolonial populations of the wood ant F. paralugubris. RESULTS: The analysis of geo-referenced microsatellite genotypes and mitochondrial haplotypes revealed the presence of cryptic clusters of genetically-differentiated nests in the three populations of F. paralugubris. Because of this spatial genetic heterogeneity, members of the same clusters were moderately but significantly related. The comparison of nuclear (microsatellite) and mitochondrial differentiation indicated that effective gene flow was male-biased in all populations. CONCLUSION: The three unicolonial populations exhibited male-biased and mostly local gene flow. The high number of queens per nest, exchanges among neighbouring nests and restricted long-distance gene flow resulted in large clusters of genetically similar nests. The positive relatedness among clustermates suggests that kin selection may still contribute to the maintenance of altruism in unicolonial populations if competition occurs among clusters.

El blog y otras herramientas comunicativas de la biblioteca del Área de Gestión Sanitaria Este de Málaga - Axarquía

In 2006 the Library of the Andalusian Public Health System (BVSSPA) is constituted as a Virtual Library which provides Resources and Services that are accessed through inter-hospital local area network (corporate intranet) and Internet. On the other hand, the Hospital de la Axarquia still did not have any institutional or self-presence on the Internet and the librarian ask the need to create a space for communication with the "digital users" of the Library of the area through a website. MATERIALS AND METHODS. The reasons why we opted for a blog were: -It was necessary to make no financial outlay for its establishment. It allowed for great versatility, both in its administration and in its management by users. -The ability to compile on the same platform different Web 2.0 communication tools. Between different options available we chose Blogger Google Inc. The blog allowed entry to the 2.0 services or Social Web in the library. The benefits offered were many, especially the visibility of the service and communication with the user. 2.0 tools that have been incorporated into the library are: content syndication (RSS) which allowed users to stay informed about updates to the blog. Share documents and other multimedia as presentations through SlideShare, images through Flickr or Picasa, or videos (YouTube). And the presence on social network like Facebook and Twitter. RESULTS. The analysis of the activity we has been traking by Google Analytics tool, helping to determine the number of blog visits. Since its stablishment, on November 17th 2006, until November 29th 2010 the blog has received 15,787 visitors, 38,422 page views were consulted, at each visit on average 2.4 pages were consulted and each visit has an average stay at the site of 4'31''. DISCUSSION. The blog has served as a communication and information tool with the user. Since the creation of the blog we have incorporated technologies and tools to interact with the user. With all the tools used we have applied the concept of "open source" and the contents were generated from the activities organized in the Knowledge Management Unit from the anatomo-clinical sessions, the training activities, dissemination events, etc. The result has been the customization of library services, contextualized in the Knowledge Management Unit - Axarquia. In social networks we have shared information and files with the professionals and the community. CONCLUSIONS. The blog has allowed us to explore technologies that allow us to communicate with the user and the community, disseminate information and documents with the participation of users and become the "Interactive Library" we aspire to be.

On Strong Citizens: A Sociological View on Cognitions and Contentious Participation

The present thesis is about cognitions of left-wing activists and the role they play to better understand contentious participation. It compares activists of three post-industrial social movement organizations in Switzerland, i.e. Solidarity across Borders defending migrant's rights, the Society of Threatened People promoting collective human rights and Greenpeace protecting the environment. It makes use of an innovative mixed methods design combining survey and interview data. The main theoretical contribution is to conceptualize an analytical tool enabling to grasp the cognitive map of these activists by putting forward the concept of strong citizen, summing up their relation to society and politics. The relation to society consists of an extensive relation to others and an interconnected vision of society. Consequently, their primary concerns include the handing of common goods and the equal treatment of individuals with regard to common goods. The relation to politics incorporates a critical and vigilant citizen. They are critical towards political authorities and they appreciate political action by organized groups of the civil society. The thesis states that only by having such worldviews activists are able to construct an injustice, agency and identity frame for the claims of their organizations. Thus, the present work delivers a parsimonious answer to the question of where an injustice, agency and identity frame comes from. It does so by a systematic analysis of four specific arguments. First, it empirically demonstrates that these activists have - at the aggregate level - specific cognitive resources compared to the general population. Second, it describes the content of this specific cognitive outlook by evaluating the appropriateness of the strong citizen concept. Third, it looks at variations between activist's communities and shows that activists of more challenging protest issues are stronger citizens than activists of more mainstream protests. Finally, cognitions are not the only part of the story if one looks at contentious participation. Other factors, i.e. social networks and biographical availability, matter too. Therefore, I test if cognitions are able to contribute in explaining differences between activists' communities if one controls for other factors. In sum, this thesis is thus a first step to demonstrate why one should be concerned about activists' cognitions. - Cette thèse s'intéresse aux cognitions des activistes de gauche et à leur rôle dans le phénomène de la participation contestataire. Des activistes de trois organisations post- industrielles en Suisse sont comparé, à savoir Solidarité sans Frontières qui défend les droits des migrants, la Société des Peuples menacés qui promeut les droits des collectivités minoritaires et Greenpeace qui oeuvre pour la protection de l'environnement. Cette recherche utilise un « mixed methods design » en combinant de manière innovant des données de sondage et d'entretiens. Ma principale contribution théorique réside dans la conceptualisation d'un outil analytique qui permet de saisir la « carte cognitive » des activistes, à travers le concept de « strong citizen » qui se réfère à la relation spécifique qu'entretiennent certains individus avec la société et la politique. Ces individus sont caractérisés par une vision inclusive et interconnectée de la société, ainsi que par une conception politique du citoyen comme critique et vigilant. Mon argument principal est celui selon lequel seuls les individus possédant ce type particulier de cognitions sont capable de construire un cadre d'injustice, d'« agency » et d'identité. Cette thèse apporte donc quelques éléments de réponse à la question de l'origine de ces cadres cognitifs qui sont cruciales pour la participation. Pour ce faire, quatre aspects spécifiques sont analysés de manière systématique. Premièrement, je démontre empiriquement, au niveau agrégé, que ces activistes possèdent effectivement des ressources cognitives spécifiques - en comparaison avec la population générale. Deuxièmement, j'analyse le contenu de ces cognitions, ce qui me permet notamment d'évaluer la pertinence et l'adéquation du concept de « strong citizen ». Troisièmement, en m'intéressant cette fois aux variations entre communautés d'activistes, je démontre que ceux réunis autour d'enjeux protestataires très revendicatifs sont, d'un point de vue cognitif, plus proches de la figure du « strong citizen » que ceux mobilisés sur des enjeux plus consensuels. Finalement, d'autres facteurs, à savoir les réseaux sociaux et la disponibilité biographique, sont intégrés à l'analyse afin de mesurer le réel pouvoir explicatif des cognitions dans l'explication des différences observées entre communautés d'activistes. A travers ces analyses, cette thèse met en avant l'importance du rôle des cognitions dans l'étude de la participation contestataire.
