Rolling Stone Brasil: aspectos de interatividade

The purpose of the present dissertation is to show the interactivity connections featured in a cultural journalism magazine's website through direct observation of its presented structure. The website chosen as object of study is Rolling Stone Brasil, April 2010 being the point of reference for analysis. Methodological support for such study has been culled from theoretical works on the principles that are necessary for the development of sampling in the observed structure. For this, are employed of concepts and strategies predicated by authors in the field of communications with emphasis on digital means is aplicated. The research indicates that the tools adopted in the website's structure comprise a potential of interactivity between the parties involved in the communication chain, and that the content therein produced may be considered as direct content of a web journalism structure

Imprensa alternativa e contracultura: o jornal brasileiro Rolling Stone de 1972

The present monograph is a historical research of one of the brazilian newspapers in a journalistic heterogeneous effervescence, referring to the proliferation of vehicles on alternative libertarians of the 60/70. The project gives visibility to the Rolling Stone newspaper as the document that disproved their own relevancy in the viability of the music production and counterculture inspired by North America, developing the repercussion of the new behavior of young flower power in the country. The personality of those who were in the journalistic team, the production schema, editorial and proposed tariffs would be in total congruency with the countercultural movement

Distribution of constitutive heterochromatin in species of triatomines with fragmentation of sex chromosomes X

Cytogenetic analyses of triatomines are considered to be important taxonomic tools. Thus, we analyzed the pattern of constitutive heterochromatin in 7 species of triatomine with fragmentation of the sex chromosome X, focusing on the cytotaxonomy of these triatomines. The species analyzed included Triatoma vitticeps, Triatoma melanocephala, Triatoma tibiamaculata, Triatoma protracta, Meccus pallidipennis, Panstrongylus megistus, and Panstrongylus lignarius. The seminiferous tubules of the adult males were subjected to C-banding. P. megistus and P. lignarius showed differences in chromosome number and disposition of constitutive heterochromatin, as only P. lignarius showed C-blocks in autosomes. C-banding can differentiate these species, since one of the sex chromosome (X) is heterochromatic in T. vitticeps. T. protracta showed C-blocks in both ends of all autosomes, T. tibiamaculata showed terminal C-dots in some autosomal pairs and M. pallidipennis did not show constitutive heterochromatin in autosomes. Thus, we confirmed the heterochromatic pattern of 7 species of insects and emphasized the importance of cytogenetic techniques for C-banding for taxonomy studies of the triatomines, which are important vectors of Chagas disease.

Use of the probability of stone formation (PSF) score to assess stone forming risk and treatment response in a cohort of Brazilian stone formers

Introduction: The aim was to confirm that PSF (probability of stone formation) changed appropriately following medical therapy on recurrent stone formers.Materials and Methods: Data were collected on 26 Brazilian stone-formers. A baseline 24-hour urine collection was performed prior to treatment. Details of the medical treatment initiated for stone-disease were recorded. A PSF calculation was performed on the 24 hour urine sample using the 7 urinary parameters required: voided volume, oxalate, calcium, urate, pH, citrate and magnesium. A repeat 24-hour urine sample was performed for PSF calculation after treatment. Comparison was made between the PSF scores before and during treatment.Results: At baseline, 20 of the 26 patients (77%) had a high PSF score (> 0.5). Of the 26 patients, 17 (65%) showed an overall reduction in their PSF profiles with a medical treatment regimen. Eleven patients (42%) changed from a high risk (PSF > 0.5) to a low risk (PSF < 0.5) and 6 patients reduced their risk score but did not change risk category. Six (23%) patients remained in a high risk category (> 0.5) during both assessments.Conclusions: The PSF score reduced following medical treatment in the majority of patients in this cohort.

Revista Rolling Stone Brasil: em busca do perfil ideal do leitor do site

O presente trabalho tem por objetivo buscar características que ajudem a definir quem é o público leitor do site da Rolling Stone Brasil, levantando a questão da migração de revistas que surgiram antes da internet para o ciberespaço. Para isso, com base em revisão bibliográfica, retornamos na história para resgatar as origens da versão impressa da publicação e das origens do próprio jornalismo de revista. Com base em uma pesquisa sobre o que se chamou de Perfis Digigraficos e com realização de entrevistas com os editores do site e da revista Rolling Stone Brasil, concluímos que este perfil, aqui chamado de ideal, não está relacionado com idade, gênero e gosto musical
