Instâncias de consagração na cibercultura: um estudo sobre a atuação do internauta no MySpace

With new technologies, there are fields of unprecedented artistic legitimation and consecration. On the Internet, MySpace is used as a social network whose peculiarity lies in the interactivity of between artists (established and independent) users and non-artists. The website has revealed new names in the music scene from the popularity they gained by its peers. To see how the communication happens within that environment, was chosen the band profile Restart, whose audience is the majority of MySpace teen (youth 12 to 17 years). The analysis of this article is part of a broader research and the results already obtained allow us to see, within the limits of the selected area, that the Internet not only introduces a new field of action, but new instances of artistic consecration.

Traições, pequenas mentiras e internet: conjugalidades contemporâneas e usos de mídias digitais

In the present paper, the authors carry out an exploratory analysis of the market of confidential online betrayals by examining the perceptions of the issue of those Ashely Madison Site users participating in the research. The ethnographic method and a multidisciplinary approach were employed in order to understand how love and market, technology and intimacy come together, and how traditional values related to family, conjugality and masculinity articulate in the world of online betrayals. Interactions between men aged between 38 and 70 were favored in the analyses.

Impacto da internet para os movimentos sociais e para a abordagem da mídia tradicional

Este artigo busca analisar os impactos que a internet trouxe para os movimentos sociais, tanto na sua organização, quanto na sua abordagem midiática, com o intuito de entender a forma de atuação das manifestações sociais no novo milênio. Com o advento da internet a grande mídia perde seu monopólio, tornando a comunicação mais democrática - apesar de ainda ser segregativa e baseada na renda. O estudo foi desenvolvido por meio da pesquisa exploratória, descritiva e analítica de cunho qualitativo e os exemplos e objetos de estudo discutidos são as manifestações que ocorreram nos últimos anos como o Occupy Wall Street (EUA) e as manifestações brasileiras ocorridas no mês de junho de 2013, mostrando sua abordagem pela mídia e o peso que a internet teve no desenrolar dos acontecimentos.

Feminismo na internet: o caso do coletivo marcha das vadias e sua página no facebook

This article analyzes how the Brazilian feminist movements utilize online social networks to expand their sphere of action and mobilization in society through understanding how is the activity of the collective Marcha das Vadias of Rio de Janeiro on your Facebook page and as this group is mobilized in the online environment to organize its annual march, here, specifically the 4th Marcha das Vadias of Rio de Janeiro. Through exploratory, descriptive and analytical qualitative research methodology and analysis of social networks on the Internet, it is concluded that the network generated by the topic "4th Marcha das Vadias of Rio de Janeiro" was central dynamic between a public clear feminist, but weak and little to comprehensive dialogue with society in general positions.

O storify e o jornalismo cidadão na internet

This study aims to understand the democratic and social potential of online citizen journalism, and how Storify can be use as a tool to achieve this goal. The focus is to analyse the use of this tool by media companies to verify if there are plurality of themes, or if there are gatekeeping of the information - such as occur in traditional media. The research will use the content analyse methodology to observe how three media companies use the website Storify: O Estado de São Paulo, Zero Hora and Veja. The results are based on the most frequent themes, which were divided into seven categories: police; politics; city; sport; technology; science and media. With this analyse we were able to concluded that, according to the theme, O Estado de Sao Paulo had, between the media companies analysed, the most plural approach, after it is Zero Hora, and lastly Veja.

Internet e democracia: a qualidade da informação sobre políticas públicas de cultura em portais de governo

Public communication comprises the dissemination of information on the various aspects of public management, with transparency and accountability, including the use of the existing technological resources. Particularly in the field of cultural policies, the right to information must be exercised as a contribution to political participation and economic expansion. This paper presents the results of research that was investigated, through analysis of the content under thirteen categories of evaluation, of the quality of information on cultural policies in web portals of the different spheres of government in Brazil. The results show the lack of information on the processes of development and implementation of policies in that field.

Experiências pedagógicas de atletismo na escola: em busca de registros na internet

O atletismo é uma modalidade esportiva pouco explorada em aulas de Educação Física Escolar. Há muitos motivos para isso, tais como: falta de espaço adequado na escola para que possa ser realizado, falta de material, desinteresse dos alunos e de professores. Em virtude disso, esta pesquisa tem como objetivo investigar as experiências pedagógicas de professores de Educação Física com o atletismo, registradas em vídeos disponibilizados na internet, mais especificamente no Youtube, verificando suas contribuições para o ensino e difusão desta modalidade esportiva na escola. Para tanto, foram coletados vídeos da rede social Youtube, a fim de elaborado um banco de dados sobre o assunto, de forma a auxiliar professores de Educação Física, incentivando-os a divulgarem seu trabalho na internet. Após a análise dos vídeos, foram criadas duas categorias: a primeira denominada Vídeo Amador e a segunda Vídeo semiamador. A partir dessas duas categorias, elaboramos 3 eixos que auxiliaram na obtenção dos resultados, que foram: Eixo 1 - Conteúdo e meios, Eixo 2 - Ambiente e fase escolar e Eixo 3 - Poder de difusão. Ao final das análises os resultados nos mostraram que o atletismo, está de certa forma sendo ensinado no âmbito escolar, mais especificamente nas aulas de Educação Física, mas como evidenciamos no Eixo 3 - Poder de difusão, os vídeos com estas experiências, não estão sendo publicados, mais que isso, não estão sendo visualizados por professores e alunos, a fim de aumentar a difusão do atletismo, tanto quanto, o ensino deste. Concluímos que a partir desta pesquisa possamos fornecer subsídios para que os professores de Educação Física possam construir, junto à escola e aos seus alunos, possibilidades de ensino-aprendizagem em torno desta modalidade esportiva, contribuindo para a sua difusão no âmbito escolar

Development of site-specific sediment quality guidelines for North and South Atlantic littoral zones: Comparison against national and international sediment quality benchmarks

We aimed to develop site-specific sediment quality guidelines (SQGs) for two estuarine and port zones in Southeastern Brazil (Santos Estuarine System and Paranagua Estuarine System) and three in Southern Spain (Ria of Huelva, Bay of Cadiz, and Bay of Algeciras), and compare these values against national and traditionally used international benchmark values. Site-specific SQGs were derived based on sediment physical-chemical, toxicological, and benthic community data integrated through multivariate analysis. This technique allowed the identification of chemicals of concern and the establishment of effects range correlatively to individual concentrations of contaminants for each site of study. The results revealed that sediments from Santos channel, as well as inner portions of the SES, are considered highly polluted (exceeding SQGs-high) by metals, PAHs and PCBs. High pollution by PAHs and some metals was found in Sao Vicente channel. In PES, sediments from inner portions (proximities of the Ponta do Mix port`s terminal and the Port of Paranagua) are highly polluted by metals and PAHs, including one zone inside the limits of an environmental protection area. In Gulf of Cadiz, SQGs exceedences were found in Ria of Huelva (all analysed metals and PAHs), in the surroundings of the Port of CAdiz (Bay of CAdiz) (metals), and in Bay of Algeciras (Ni and PAHs). The site-specific SQGs derived in this study are more restricted than national SQGs applied in Brazil and Spain, as well as international guidelines. This finding confirms the importance of the development of site-specific SQGs to support the characterisation of sediments and dredged material. The use of the same methodology to derive SQGs in Brazilian and Spanish port zones confirmed the applicability of this technique with an international scope and provided a harmonised methodology for site-specific SQGs derivation.

Lapa das boleiras rockshelter: stratigraphy and formation processes at a paleoamerican site in Central Brazil

Lapa clas Boleiras rockshelter, a Paleoamerican archaeological site in Central Brazil, was intensely occupied by humans from 10,000 C-14 BP (11.8 cal kyr BP), until approximately 7500 C-14 BP (8.4 cal kyr BP). In this paper we present some interpretations about the formation processes operating on the site. One of our main conclusions is that the bulk of accumulated sediments at the site is of anthropogenic origin: they are constituted by volumetrically significant quantities of plant ash remains, what is somewhat unexpectedly in view of prevailing models about the lifestyle of Paleoamerican hunter-gatherers in South America. The evidence we discuss below is also consistent with paleoenvironmental data that suggest a dry period during the mid-Holocene in the region, probably leading to a decrease in human occupation [Araujo, A.G.M., Neves, W., Pilo, L.B., Atui, J.P., 2005. Holocene dryness and human Occupation in Brazil during the `Archaic Gap`. Quaternary Research 64, 298-307]. We surmise that both factors underpin a surprising reduction in sediment accumulation at the site during the mid-Holocene. (C) 2008 Published by Elsevier Ltd.

Aberrant transcript produced by a splice donor site deletion in the TECTA gene is associated with autosomal dominant deafness in a Brazilian family

We ascertained a Brazilian family with nine individuals affected by autosomal dominant nonsyndromic sensorineural hearing loss. The bilateral hearing loss affected mainly mid-high frequencies, was apparently stable with an early onset. Microsatellites close to the DFNA8/DFNA12 locus, which harbors the TECTA gene, showed significant multipoint lod scores (32) close to marker D11S4107. Sequencing of the exons and exon-intron boundaries of the TECTA gene in one affected subject revealed the deletion c.5383 + 5delGTGA in the 5' end of intron 16, that includes the last two bases of the donor splice site consensus sequence. This mutation segregates with deafness within the family. To date, 33 different TECTA mutations associated with autossomal dominant hearing loss have been described. Among them is the mutation reported herein, first described by Hildebrand et al. (2011) in a UK family. The audioprofiles from the UK and Brazilian families were similar. In order to investigate the transcripts produced by the mutated allele, we performed cDNA analysis of a lymphoblastoid cell line from an affected heterozygote with the c.5383 + 5delGTGA and a noncarrier from the same family. The analysis allowed us to identify an aberrant transcript with skipping of exon 16, without affecting the reading frame. One of the dominant TECTA mutations already described, a synonymous substitution in exon 16 (c.5331 G<A), was also shown to affect splicing resulting in an aberrant transcript lacking exon 16. Despite the difference in the DNA level, both the synonymous substitution in exon 16 (c.5331 G<A) and the mutation described herein affect splicing of exon 16, leading to its skipping. At the protein level they would have the same effect, an in-frame deletion of 37 amino-acids (p.S1758Y/G1759_N1795del) probably leading to an impaired function of the ZP domain. Thus, like the TECTA missense mutations associated with dominant hearing loss, the c5383 + 5delGTGA mutation does not have an inactivating effect on the protein. (C) 2012 Elsevier B.V.
