DIFFERENT MEDIA, DIFFERENT TYPES OF COLLECTIVE WORK IN ONLINE CONTINUING TEACHER EDUCATION: WOULD YOU PASS THE PEN, PLEASE?

This paper presents some findings regarding the interaction between different computer interfaces and different types of collective work. We want to claim that design in online learning environments has a paramount role in the type of collaboration that happens among participants. In this paper, we report on data that illustrate how teachers can collaborate online in order to learn how to use geometry software in teaching activities. A virtual environment which allows that construction to be carried out collectively, even if the participants are not sharing a classroom, is the setting for the research presented in this paper.

Jornalismo econômico como exercício da cidadania: uma análise da divulgação econômica na mídia oficial e nos veículos Universo Online e O Estado de São Paulo

The present study had the intention to demonstrate how the language used by official sources of economy helps to keep the limitation and lack of accessibility of economic journalism to non-specialist readers. Over two weeks, we compared the disclosures in the economics editorial office of the site Universo Online and the newspaper O Estado de S. Paulo to those cited in official reports. From this analysis of more than 50 issues selected for the sample, was observed how the technical language used by the official press makes more difficult the access to information and citizenship. Besides the comparison and description of the reports, the study involved the content analysis employed in the media. It was noted the presence of biased approaches and materials poorly cleared. The language used in many cases was not appropriate to the type of audience for which the news was heading. One of the most serious problems, perhaps, was the copy and paraphrase of press releases. The reports, most are limited to the specialist showed, contrary to the duty of public transparency, while highlighting the problems, the study also showed well-written texts that indicate a promising future for citizen and economic journalism

Chemical and morphological features of dental composite resin: influence of light curing units and immersion media

Aims: The study evaluated the influence of light curing units and immersionmedia on superficial morphology and chemistry of the nanofilled composite resin Supreme XT (3M)through the EDX analysis and SEM evaluation. Light curing units with different power densitiesand mode of application used were XL 3000 (480 mW/cm2), Jet Lite 4000 Plus (1230mW/cm2), andUltralume Led 5 (790 mW/cm2) and immersion media were artificial saliva, Coke1, tea and coffee,totaling 12 experimental groups. Specimens (10 mm 3 2 mm) were immersed in each respectivesolution for 5 min, three times a day, during 60 days and stored in artificial saliva at 378C 6 18Cbetween immersion periods. Topography and chemical analysis was qualitative. Findings: Groupsimmersed in artificial saliva, showed homogeneous degradation of matrix and deposition of calciumat the material surface. Regarding coffee, there was a reasonable chemical degradation with loss ofload particles and deposition of ions. For tea, superficial degradation occurred in specific areaswith deposition of calcium, carbon, potassium and phosphorus. For Coke1, excessive matrix degra-dation and loss of load particles with deposition of calcium, sodium, and potassium. Conclusion:Light curing units did not influence the superficial morphology of composite resin tested, but theimmersion beverages did. Coke1affected material’s surface more than did the other tested drinks.Microsc. Res. Tech. 73:176–181, 2010.

Effects of immersion media and repolishing on color stability and superficial morphology of nanofilled composite resin

This study evaluated the influence of fluoride mouth rinses and repolishing on the superficial morphology and color stability of nanofilled resin. About 150 specimens were prepared and polished using aluminum oxide discs for 15 s with a pressure of 2 kg. The experimental groups were divided according to the immersion medium (artificial saliva, 0.5% sodium fluoride, Fluordent Reach, Oral B, Fluorgard) and repolishing procedure (without and with). The specimens were continuously immersed for 1 week. Thereafter, half of each sample was repolished. A color reading was performed after 24 h of immersion in the artificial saliva baseline, after continuous immersion, and after repolishing. The superficial morphology was examined using scanning electron microscopy (SEM) in a qualitative way. Color change (∆E) data were submitted to a mixed analysis of variance using a Shapiro-Wilk test (p>0.05 for the different immersion media) and Sidak's test (p<0.05 for the differences between groups). In the interaction between the repolishing and the immersion media, Fluorgard showed a statistical difference between the ∆E values with and without repolishing (p<0.0001). On the SEM observations, both Fluordent Reach and Fluorgard caused degradation of the superficial resinous matrix of the composite after continuous immersion. This matrix was removed after repolishing.

A semiose peirceana no jornalismo colaborativo online

The purpose of this article is to think the online collaborative journalism from the perspective of semiosis in Charles Sanders Peirce. It seeks to define the formal elements of language hypermedia web, beyond the concepts of semiosis, sign, object and interpretant. Thus, paths are indicated for understanding how different aspects of the news can emerge and coexist in mediating the journalistic own website, marked by the decentralization of the production and dissemination of media content, as opposed to mediation system based on broadcast journalism. There is also a small survey of the evolution of Brazilian collaborative journalism on the web, showing that there is still a tendency to keep the logic of journalism massive unidirectional.

O uso das redes sociais online nas interações de produtores e receptores de televisão

This paper discusses the possibility of receiver’s participation in the production of television content mediated by online social networks. Buoyed by media convergence, this research demonstrates how the receiver has been working in online digital media such as TV can take advantage of the specific interaction between the medias to promote the creation of collaborative content, in which the user of social network may interfere the result of the product developed, becoming a new mediatic protagonist. Tool not so used for the production of television that slowly begins to enter the virtual reality, the forging of this new compose process would not only entertain the receiver, but also enrich the language and content television constantly criticized. This study shows the influence of the television medium in which is discussed online, the attitude still shy of the user in content production, and discusses the potential of social networks as a channel of communication between producers and receivers. This work is structured from the definition of social network, in addition to conducting the study what kind of interaction between TV and online social networks is practiced today. Finally, debate whether the potential interaction between TV and social networks is used to its fullest.
