Scientific collaboration network among Brazilian universities: an analysis in Dentistry area

This paper analyses the scientific collaboration network formed by the Brazilian universities that investigate in dentistry area. The constructed network is based on the published documents in the Scopus (Elsevier) database covering a period of 10 (ten) years. It is used social network analysis as the best methodological approach to visualize the capacity for collaboration, dissemination and transmission of new knowledge among universities. Cohesion and density of the collaboration network is analyzed, as well as the centrality of the universities as key-actors and the occurrence of subgroups within the network. Data were analyzed using the software UCINET and NetDraw. The number of documents published by each university was used as an indicator of its scientific production.

A matemática no ciberespaço: um olhar fenomenológico para a expressão dos sujeitos

With the implementation of new technologies on the world stage of communication, Internet access has become increasingly numerous. Being sought by this means all kinds of information, from knowledge to entertainment. This paper intends to report the experience in two communities of the Internet, particularly in the social network Orkut, entitled I Hate Mathematics and I Love Mathematics, whose members are students, teachers and people who want to express how they feel about mathematics. The goal is to understand what took the members of these communities to hate or love Mathematics, clarifying the nature of the network Orkut and its contribution to mathematics education. For the analysis of data from field work, we use the phenomenological approach. The procedures followed by such approach allowed us to build four open categories: Research and Background, revealing that the research activities allow students to develop strategies, develop creativity and shows that what is learned in classroom is not just an accumulation of knowledge; Teacher's Role shows that it is necessary that the teacher understands the meaning of being a teacher and worry about being a student; Acquisition Technique, it is necessary that students be able to understand what is done and how it is done, and Sense of What is Done, to do is not directly linked to comprehend. The interpretation of these categories helped us understand the investigated giving us source to analyze how Information and Communication Technologies (ICT) can help the teacher understand the student's relationship with Mathematics

Análisis organizacional del partido de la democracia social brasileña en el estado de San Pablo (1988-2006)

The article represents a theoretical and methodological approach to the analysis of organizational dynamics of political parties today, based on a study of the Party of Brazilian Social Democracy (PSDB) in the State of Sao Pãulo (period between 1988 to 2006). It is hypothesized that the structure and the institutional rules of a particular party, or even their election results, are insufficient to explain the inner workings, such as the role of party organization in the electoral system. An approach that articulates the relationship patterns, election results and posts held in the party, identified the factors that explain the political capital that circulated within the party and ensured its organizational dynamics over the period analyzed.

Social networks on the Internet: a practical investigation about file sharing on Facebook

The social networks on the internet have experienced rapid growth and joined millions of users in Brazil and throughout the world. Such networks allow groups of people to communicate and exchange information. Sharing information in files is also a growing activity on the internet and is done in various ways. However, applications are not yet available to enable file sharing on Facebook, the premier social network today. This study aims to investigate how users use Facebook, and their practices for file sharing. Due to the experimental nature of this research, we opted for a data collection survey, applied over the web. From the data analysis, we have found a frequent use of file sharing, but no interest in paid services. As for Facebook, there was an extensive use of applications. The set of results shows a favourable scenario for applications that allow file sharing on Facebook.

Gênero, cultura e rede social: a construção social da desigualdade de gênero por meio da linguagem

Based on systemic-cybernetic-new paradigm vision and social constructionism, the paper is an invitation to reflect on the importance of language in the maintenance and the possibility of changing unequal relational patterns, mainly related to issues of gender. Studies on language and verbal behavior of women and men, besides their representation in the media, are examples to illustrate the need advocated here, to changing patterns of inequality guided by gender differences that influence and are influenced by the culture, conveyed in our social network. This paper is a contribution for the clinical work with families and couples, from the perspective of the current behaviors, based on refrains spread by the media which became popular, since it is based on clinical and nonclinical observations about human relationships and its representation in the media and artistic productions.

Disentangling social networks from spatiotemporal dynamics: the temporal structure of a dolphin society

Social networks are static illustrations of dynamic societies, within which social interactions are constantly changing. Fundamental sources of variation include ranging behaviour and temporal demographic changes. Spatiotemporal dynamics can favour or limit opportunities for individuals to interact, and then a network may not essentially represent social processes. We examined whether a social network can embed such nonsocial effects in its topology, whereby emerging modules depict spatially or temporally segregated individuals. To this end, we applied a combination of spatial, temporal and demographic analyses to a long-term study of the association patterns of Guiana dolphins, Sotalia guianensis. We found that association patterns are organized into a modular social network. Space use was unlikely to reflect these modules, since dolphins' ranging behaviour clearly overlapped. However, a temporal demographic turnover, caused by the exit/entrance of individuals (most likely emigration/immigration), defined three modules of associations occurring at different times. Although this factor could mask real social processes, we identified the temporal scale that allowed us to account for these demographic effects. By looking within this turnover period (32 months), we assessed fission-fusion dynamics of the poorly known social organization of Guiana dolphins. We highlight that spatiotemporal dynamics can strongly influence the structure of social networks. Our findings show that hypothetical social units can emerge due to the temporal opportunities for individuals to interact. Therefore, a thorough search for a satisfactory spatiotemporal scale that removes such nonsocial noise is critical when analysing a social system.

Social cliques in male northern muriquis Brachyteles hypoxanthus

Analyses of spatial relationships and social interactions provide insights into the social structure of animal societies and the ways in which social preferences among and between dyads affect higher order social relationships. In this paper we describe the patterns of spatial associations and social interactions among adult male northern muriquis in order to evaluate the dynamics of their social networks above the dyadic levels. Systematic observations were made on the 17 adult males present in a multi-male/multi-female group from April 2004 through February 2005, and in July 2005. Analyses of their spatial relationships identified two distinct male cliques; some adult males (called "N" males) were more connected to the females and immatures than other adult males ("MU" males), which were more connected to one another. Affiliative interactions were significantly higher among dyads belonging to the same clique than to different cliques. Although frequencies of dyadic agonistic interactions were similarly low among individuals within and between cliques, MU males appeared to be subordinate to N males. Nonetheless, there were no significant differences in the copulation rates estimated for MU males and N males. Mutual benefits of cooperation between MU and N cliques in intergroup encounters might explain their ongoing associations in the same mixed-sex group [Current Zoology 58 (2): 342-352, 2012].

Desarrollo de un sistema de videoconferencia en HTML 5.0

[ES] Webcam App es una aplicación que tiene como principal objetivo social que las personas puedan realizar videoconferencias a través de la web de forma gratuita y sencilla. Para el desarrollo de la misma, fueron de gran utilidad los elementos que brinda HTML5.0 para dar soporte multimedia: y . También, se usan dos de las APIs que implementa WebRTC para la trasmisión de audio y video en tiempo real, obtenidos desde la webcam: MediaStream (getUserMedia) y RTCPeerConnection. Para soportar esta aplicación se elige Node.js como servidor web, pues entre sus puntos fuertes está la capacidad de mantener varias conexiones abiertas, característica fundamental en una aplicación de videollamadas, donde miles de usuarios crean y envían solicitudes de conexión simultáneamente. Con el fin de aportarle una apariencia agradable a la aplicación, un entorno usable y conocido para los usuarios, se utiliza CMS Elgg como marco de red social. CMS Elgg provee de funcionalidades comunes, como por ejemplo: conectar con amigos, enviar mensajes, compartir contenido. Como metodología base se usa el Proceso Unificado de Desarrollo de Software, posibilitando que la realización de este trabajo se haya hecho de una manera organizada y se obtuvieran artefactos para el desarrollo. Como resultado del trabajo, se obtiene una solución Open Source que sirve como un modelo de comunicación en tiempo real sin necesidad de descargar, instalar o actualizar ningún complemento de terceros y que demuestra la fiabilidad de los sistemas basados en HTML5 y WebRTC.
