Biogeographical systems can be analyzed as networks of species and geographical units. Within such a biogeographical network, individual species may differ fundamentally in their linkage pattern, and therefore hold different topological roles. To advance our understanding of the relationship between species traits and large-scale species distribution patterns in archipelagos, we use a network approach to classify birds as one of four biogeographical species roles: peripherals, connectors, module hubs, and network hubs. These roles are based upon the position of species within the modular network of islands and species in Wallacea and the West Indies. We test whether species traits - including habitat requirements, altitudinal range-span, feeding guild, trophic level, and body length - correlate with species roles. In both archipelagos, habitat requirements, altitudinal range-span and body length show strong relations to species roles. In particular, species that occupy coastal- and open habitats, as well as habitat generalists, show higher proportions of connectors and network hubs and thus tend to span several biogeographical modules (i.e. subregions). Likewise, large body size and a wide altitudinal range-span are related to a wide distribution on many islands and across several biogeographical modules. On the other hand, species restricted to interior forest are mainly characterized as peripherals and, thus, have narrow and localized distributions within biogeographical modules rather than across the archipelago-wide network. These results suggest that the ecological amplitude of a species is highly related to its geographical distribution within and across bio geographical subregions and furthermore supports the idea that large-scale species distributions relate to distributions at the local community level. We finally discuss how our biogeographical species roles may correspond to the stages of the taxon cycle and other prominent theories of species assembly. © 2013 The Authors.

The successive crises for which has passed in the world economy since the years 1970, together with the United States 'hegemonic crisis, have created the conditions for the reordering and the construction of a multipolar world, with the increasing importance of some peripheral countries into the world economy, particularly with regard to capital flows. This article represents an effort to bring to light the analysis on the decrease of importance of developed countries in world investment flows and corresponding increase in the relevance of some peripheral countries. The objective underlying the text is understanding the expansion of space circuits of production of multinational companies in Latin America (Multilatinas) at different spatial scales, by means of an analysis of the temporal, spatial and sectoral dimensions of the investments. The methodological procedures adopted covered survey, selection and bibliographic data compilation, reading in international organizations (UNCTAD and ECLAC), systematization of data, analysis of data in the light of the theoretical reflections.

The traditional characteristics and challenges for organizing and searching information on the World Wide Web are outlined and reviewed. The classification features of two of these methods, such as Google, in the case of automated search engines, and Yahoo! Directory, in the case of subject directories are analyzed. Recent advances in the Semantic Web, particularly the growing application of ontologies and Linked Data are also reviewed. Finally, some problems and prospects related to the use of classification and indexing on the World Wide Web are discussed, emphasizing the need of rethinking the role of classification in the organization of these resources and outlining the possibilities of applying Ranganathan's facet theories of classification.

The individuals, mostly born biologically prepared to develop the many different aspects: cognitive, motor and affective, however, only the biological factor doesn’t possible the full development of these. Theories of the different types of knowledge about the process of teaching and learning and your relation with the affective-cognitive aspects intend explain how this individual can to evolve completely. This end of course work presupposes that the interactions of the individual with the physical and civil are essential to the development of learning. In this sense, the educational institution understood as a socializing environment and disseminator of knowledge, historically accumulated, will be then a space where affectivity and learning should be at least theoretically, favored by the relations that are established inside the same. So, the research presented in this study, have how objective, show how to set in the practice educational the relation between affect and learning considering the observations, interviews that search to highlight real situations, where are confirmed a relation between processes. From the presentation of the central ideas of these researches, we are evidencing the concept of affection and how pedagogical practice promotes the relation between affect and cognition

This project analyses in theory the transformations that have occurred in the information society in the range of the organizational communication, developing the internet historical trajectory as a technology of transformation. We highlight the cyber culture study as a cultural expression that emerges with the current society needs, observed by an optic that focuses on digital communication, emphasizing the digital environment as a space for information trade, in the interior premise of communication: the relationship. The organizations will be approached in the project through a channel for communication, in the digital range, besides the traditional forms. In regards to the enterprises we will study in depth the consumer of this society of consumerism, with a special look at the generation Y, deeply inserted in this virtual context, describing the current type of consumption, mainly the relations of consumption with the social medias. After this transforming process in which individuals are inserted in the digital environment we intend to focus in the corporate digital communication, analyzing the organizational digital communication in the contemporary society. We emphasize the theories of Public Relations, one of the main activities, able to do planning, to put together and execute the strategies that will be used in the social medias as a form of corporate digital communication. We explicit Twitter as a tool of the corporate digital communication, because it reaffirms the theories described throughout the research as one of the most essential social media to turn loyal the relationship between the consumer and the organization in real time, as an example is the organization “camisetaria” that became a success case in the social medias; we detail the participation of the company on Twitter and the reach of this network through it’s strategies in the corporate digital communication
