O estudo aponta como a internet ampliou as possibilidades de comunicação dos cidadãos de uma forma que não era possível no período do controle e concentração dos meios broadcasting sobre a informação social, assim, oferecendo espaço para a livre circulação de informação e novas possibilidades de comunicação. Entretanto, ressalta que ainda há assimetrias tanto do ponto de vista do acesso quanto do uso da rede em todas as suas potencialidades. Verifica que o atual momento ainda é de disputas em relação à legislação que diz respeito aos direitos e deveres dos que utilizam a rede. O trabalho foi realizado por meio de pesquisa bibliográfica e documental, tendo com base autores que pesquisam sobre as áreas da Comunicação, Tecnologias Digitais, Direito à Informação Social Livre e Legislação de internet, como Cicília Peruzzo, Manuel Castells, Rousiley Maia, Sérgio Amadeu da Silveira, Tim Wu, Tim Berners-Lee, Walter Lima Junior, Wilson Gomes e Yochai Benkler. O resultado da pesquisa demonstra que no cenário brasileiro, as desigualdades socioeconômicas são fator de desigualdade tanto em relação ao acesso quanto aos usos da internet, sendo dificultador para quem desejar se apropriar com liberdade deste desenvolvimento tecnológico. Portanto, cabe ao setor público interferir com vistas à diminuição das assimetrias informativas para garantir o direito de comunicação dos brasileiros no espaço de comunicação digital conectada.

Os sistemas comunicacionais têm presenciado alterações expressivas desde a chegada da internet, onde os dispositivos participativos crescem a cada dia, fruto do processo cada vez mais evidente de uma sociedade midiatizada. O trabalho aborda o tema das Manifestações de Junho, ocorridas no Brasil, busca evidenciar os tensionamentos do discurso da grande imprensa frente a cobertura da mídia alternativa, reflete quais foram os desdobramentos de uma das principais manifestações que o país já presenciou e analisa a circulação de sentidos nos eventos ocorridos em 2013. Para tanto, combina uma pesquisa bibliográfica e histórica com pesquisa empírica voltada à análise de narrativas das colunas do jornalista Arnaldo Jabor para a Rádio CBN, durante as manifestações, como também de dois comentários em vídeo de Jabor, para o Jornal da Globo, da TV Globo. E para evidenciar o referencial teórico da presente pesquisa, analisou-se um terceiro vídeo, que tem como título La Hipocresia de los Medios, fruto da edição do programa Bajada de Línea, da TV Argentina, que repercute as falas de Arnaldo Jabor, transforma-se literalmente em uma terceira fala, evidenciando a mudança de opinião e confirmando que a midiatização afeta o modelo clássico de comunicação.

Dengue is a viral disease transmitted by female mosquitoes from genus Aedes, the principal urban vector is Aedes aegypti. Actually dengue has caused, in global scale, substantial morbidity and mortality. Four serotypes (antigenically distinct) are known: DENV-1, DENV-2, DENV-3 and DENV-4. The objective of this study was described the epidemiological profile dengue in the states of Rio Grande do Norte (RN) and Paraíba (PB), 2013. For that, suspected cases of dengue were studied, received for Laboratory of Molecular Biology of infectious disease and cancer (LADIC-UFRN) from different Health Units from RN and PB between January and December of 2013. The viral RNA was obtained from serum samples of patient from health units from RN and PB. It were studied 478 suspected cases of dengue , 252 (52,7%) from Rio Grande do Norte and 226 (47,3%) from Paraíba, showeds a global rate of infection global prevalence of 29,7% (142/478). The co-circulation of three serotypes was observed: DENV-1 (9,8% [14/142]), DENV-2 (3,5% [5/142]) and DENV-4 (86,7% [123/142]). People between 21-30 years old were the most affected by the disease during all the period of the study, representing 63,7% of the cases in both states. The genus most affected was female, representing 63,3% of cases in both states. Pau dos Ferros, Rio Grande do Norte, had the highest circulation of disease, with 8,2% (8/97) of cases. In Paraíba, the city most affected was João Pessoa, with (80% (36/45) of cases. The months with the biggest viral circulation in RN and PB were March and August, respectively. These results are very important to understanding the dengue viral activity in RN and PB, providing data that can guide control actions of this disease in support to local control programs

This re search analyzes the talks dynamics about policy established in YouTube symbolic space. We are interested in examining the way in which the commentators of the video " Globo e os Protestos " articulated in the field intended for comments, a public space directed to the dissemination and circulation of meanings about policy issues. The video studied was published by PC Siqueira and Diego Quint eiro , during the June 2013 protests in Br azil, to direct the political understanding of the movement lived in that period. According to them, the protests had left political position and therefore the protesters should reject the coverage by TV Globo (a comunication vehicle with ideals of right) and allow the participation of political parties linked to the ideological left spectrum. This narrative generated empathy and controversy betwe en commentators, which produced in the comments, an intense argumentative process about these theses (right and left). To understand the phenomenon, we conducted an exploratory qualitative research, the main methodological procedure was a ethnomethodological discourse analysis. We seek the observation of the ways in which the commentators es tablished talks about politics in the comments space, for, thereafter , organize categories of analysis based on identified discursive recurrences. The empirical reflections are supported from discussions about the YouTube potential, while digital media com prising massive strategies and while articulating space in the engagement of individuals in political issues; also confront the aspects involved in the conversation practices that results in sociability dynamics and , especially , in conflict, on the socio - t echnical networks; and finally, we propose a reflection about the circuit actuation in which the people take ownership and realize new readings about the products received. Concluding that the use of digital media , such as YouTube, has caused significant c hanges in the forms of production and reception of symbolic products and ways in which people participate in political issues concerning life in society.

This research seeks to understand how the problem of information security is treated in Brazil by the public thematization and also how it can affect the political and economic aspects of both Brazilian companies and government by using a study case based on the document leak event of the National Security Agency by Snowden. For this, the study case of sites, blogs and news portal coverage was carried out from the perspective of evidential paradigm, studies of movement and event concept. We are interested in examining how the media handles the information security topic and what its impact on national and international political relations. The subject matter was considered the largest data leakage in history of the NSA, which ranks as the world's largest agency of expression intelligence. This leak caused great repercussions in Brazil since it was revealed that the country was the most watched by the United States of America, behind only USA itself. The consequences were: a big tension between Brazil and the US and a public discussion about privacy and freedom on Internet. The research analyzed 256 publications released by Brazilian media outlets in digital media, in the period between June and July 2013.
