Social networks can measure the scientific collaboration among researchers, institutions and countries, making visible the investigative behavior of any field. Indexing language is a theme primarily approached by the area of information organization and representation. This paper presents the formation of social networks related to the indexing language theme using the available curricula on the Lattes Platform. Co-authorship analyses were done for researchers and institutions, as well as information about the journals most used to communicate the theme and knowledge areas that deal with investigations of indexing languages. It was found that co-authorship index is high, but the social networks of the respective theme are designed in a localized way.

This study aimed to identify the post-graduation programs in Speech Pathology in Brazil, present the production of professors of these programs in the aspects of documentary typologies and present the evolution of this production up to year 2011, delineate the collaborative networks between professors and between institutions, as well as to present the indicators of networks. By accessing the Capes website, eight post-graduation programs were found, revealing a list with a total of 118 professors in Brazil. Data were extracted from the Lattes Platform using the ScriptLattes. The graphs were created in Excel, the networks were traced using the software Ucinet and the density and centrality indicators were calculated. It was observed that most courses are located in the South and Southeast regions of the country and, even though this is a recent field, it presents a significant collaborative network.

Biological processes are complex and possess emergent properties that can not be explained or predict by reductionism methods. To overcome the limitations of reductionism, researchers have been used a group of methods known as systems biology, a new interdisciplinary eld of study aiming to understand the non-linear interactions among components embedded in biological processes. These interactions can be represented by a mathematical object called graph or network, where the elements are represented by nodes and the interactions by edges that link pair of nodes. The networks can be classi- ed according to their topologies: if node degrees follow a Poisson distribution in a given network, i.e. most nodes have approximately the same number of links, this is a random network; if node degrees follow a power-law distribution in a given network, i.e. small number of high-degree nodes and high number of low-degree nodes, this is a scale-free network. Moreover, networks can be classi ed as hierarchical or non-hierarchical. In this study, we analised Escherichia coli and Saccharomyces cerevisiae integrated molecular networks, which have protein-protein interaction, metabolic and transcriptional regulation interactions. By using computational methods, such as MathematicaR , and data collected from public databases, we calculated four topological parameters: the degree distribution P(k), the clustering coe cient C(k), the closeness centrality CC(k) and the betweenness centrality CB(k). P(k) is a function that calculates the total number of nodes with k degree connection and is used to classify the network as random or scale-free. C(k) shows if a network is hierarchical, i.e. if the clusterization coe cient depends on node degree. CC(k) is an indicator of how much a node it is in the lesse way among others some nodes of the network and the CB(k) is a pointer of how a particular node is among several ...(Complete abstract click electronic access below)

The collective purchases translate into new business strategies that so far are poorly studied, but they have modifyied considerably the forms of consumption through the consumers individualisation, which causes changes in society's routine. The analysis of the theme was performed by study cases of collective shopping places in the city of Campinas, country of the state of São Paulo, and on its influence in the metropolitan area, which intented to understand, through custumers interviews, the contradictions and peculiarities of this service that has increased each day more . For this purpose, the research methodology is focused on the consumer , that's because the process of productive change tied to forms of trade and distribution of goods have been transforming social values considerably, based increasingly on impulsive consumming . Thus, to understand how the electronic commerce and more specifically the collective shopping websites works, it's necessary to examine the forms of commerce and the consumer's behavior in order to explain the city organization and the contradictions of the geographic space

O objetivo desse trabalho foi discutir a participação das diferentes instituições integrantes da Rede de Agroecologia Mantiqueira-Mogiana, organização social com enfoque no desenvolvimento comunitário coordenada pela Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), que trata da construção coletiva do aprendizado e da troca de experiências e intercâmbio de tecnologias em Agroecologia. Para tanto, foi proposto que as instituições participantes da Rede de Agroecologia respondessem um questionário que abrangia tópicos acerca da participação de tais instituições bem como de estruturação e gestão da Rede. Tendo o estudo tratado da participação das instituições, foram contatados os profissionais dessas organizações envolvidos diretamente com as atividades da Rede, por ser de conhecimento prévio que tais instituições são representadas no projeto por um determinado profissional com maior identificação pessoal com o campo da Agroecologia. Tais opiniões foram posteriormente analisadas enquanto representativas das instituições as quais esses profissionais estão vinculados. Os dados obtidos revelaram a necessidade de um acordo formal entre a Empresa Brasileira de Pesquisa Agropecuária e as instituições participantes do projeto, o que permitiria que os profissionais pudessem participar de forma mais efetiva das atividades da Rede de Agroecologia, integrando as atividades do Colegiado Gestor com as atividades das instituições as quais esses profissionais são vinculados. Foi possível observar também que para que os objetivos de uma determinada rede de desenvolvimento comunitário sejam atingidos é necessário que estes estejam em consonância com as motivações que as instituições parceiras apresentam para participar de tal rede. Dessa forma, é possível congregar esforços de todas as partes para que o objetivo coletivo seja atingido.

In recent literature, the concept of policy subsystem has occupied a central place in many theoretical models, it is considered prime unit of analysis in recent approaches to the policy process. Subject of intense theoretical discussion, when compared to related concepts such as policy communities, policy networks and policy issues, these concepts can contribute to the analysis of political participation process, characteristic of democratic governments. This present study aims to present a critical review of the literature on subsystems, policy issues, policy networks and policy communities, as well as discuss these concepts emphasizing the participatory potential of the actors who make up these spaces, seeking to contribute to the dialogue of studies in public policy and participation policy in Brazil.

Organizations have been facing several challenges to survive in a world in constant transformation. In light of that, new management models need to be incorporated to the organizational dynamics in order to achieve competitive advantages. The inter-firm networks establish a particular form means of cooperation as a fundamental element, as there can be ties of diverse nature to justify the relationships. These are interorganizations or inter-firms, formed by people who maintain the relationships to improve the overall performance of the network and of the participants. Thus, the Education Institutions, considered as organizations, which have the objective to disseminate knowledge and form professionals who contribute to the growth of a nation, also make use of this type of arrangement. Considering the raised questions, this article aims to demonstrate the applicability of a business network mapping technique at Higher Education Institutions. It also presents the possibility to perform the comparative analysis of the intensity of the relationship observed in a private and in a public institution, in the State of São Paulo. By applying the comparative analysis, this study also presents the relationship among the people involved at strategic and tactical levels of each institution, taking into account each one s peculiarities.

Considerando a potencialidade apresentada pelas tecnologias de informação e comunicação na atualidade este estudo aponta as formas pelas quais grupos sociais mobilizados em torno de uma vinculação étnica podem se servir do aparato da Internet, em especial do World Wide Web, para divulgar aspectos de sua cultura e modo de vida. Trata-se de grupos dedicados ao ensino, transmissão, preservação e disseminação da tradição gaúcha vinculados aos Centros de Tradições Gaúchas (CTG). Especificamente, este artigo apresenta como os tradicionalistas gaúchos estabelecem suas redes sociais na Internet, constituindo comunidades virtuais em torno do tema cultura e tradição gaúcha, fazendo uso dos serviços da Web 2.0. Abordam-se neste estudo experiências que indicam que o terreno virtual é fértil e possível de transformar e revolucionar o campo das tradições, sua preservação, disseminação e (re)invenção. No contexto de modernidade tardia esse recurso não pode ser descartado. Independente da análise se situar no campo econômico, político ou cultural, entre tantos outros, o fato é que a Internet se constitui num meio eficaz e abrangente de transmitir, ensinar e preservar conteúdos de todos os tipos.
