A comunicação midiática da tecnociência: uma leitura a partir do enfoque cts

This paper has two basic aims. The first one is to propose a discussion about the journalistic potential of information regarding patents, trying to identify using some experiences, the characteristics of this techno-scientific product that, somehow, draws the attention of the media. The second one is to understand the relationship between media and patents from the perspective of the studies on Science, Technology and Society (STS). The following assumption is made: the media treatment of patents is still strongly marked by economic bias and follows the logic of the supply-linear model, under which, among other important ideas, basic research is followed by applied research and, then, by technological developments that allow the launch of a new product bringing benefits for society. The paper presents results from case studies of science communication involving patents of the Federal University of Silo Carlos (UFSCar), Brazil, indicating that they are an important source of news for the media, and emphasizing the importance of the media in the national and international discussions about the protection of intellectual work.

Um estudo exploratório sobre o infotretenimento como estratégia na produção de conteúdos para telejornalismo digital

This paper is an exploratory research based on bibliography which aims to establish relationships between the concepts of TV Journalism in the Digital TV with characteristics of Infotainment genre, defined as the model program that adopts the formula of a hybrid production. It follows a concept which is between the information and the entertainment. From this study, it is argued the possibility of the elaboration of news program to the Digital TV that transmits information with through entertainment (Infotainment)

A influência do contexto multimidiático na configuração atual do telejornalismo

The TV news, like other productions for television, are in the process of adaptation of its discursive structures and its production as a consequence of the structures of the digital systems. Focusing not only the formatting, but mainly on the routines, its possible to notice the emergence of a new dynamic of production and consumption of information. Interactivity is the resource that has mobilized the most effort in the adaptation of television companies, anticipating the trend towards a more strengthening receiver role in communication relationship, which should be intensified by the convergence of medias with the deployment of Brazilian digital TV. While this is not realized, producers encourage a forged approach of receivers, since the proposal is not fully enforceable, either because of limitations in the routine production or in the technological devices. Then, the enunciative strategy of interactivity seeks to renew the social bond between the TV news and its audience.

A Copa do Mundo de 2010 entre o jornalismo e o entretenimento: uma análise do Central da Copa, da TV Globo

The proposed paper aims to understand and analyze how the sporting television journalism has changed in Brazil, affecting the coverage of major events like the World Cup. The impact of these changes are reflected in the use of interactivity, entertainment and presentation of news, in pictures and on television news programs inserted in Brazilian TV News. The study proposes to analyze, through theories of journalism and content analysis, as two seemingly opposing concepts (journalism and entertainment) were put into perspective by the Central Cup television program, aired during the year 2010 by Globo television, on the occasion of the World Cup in South Africa.

On determining spectral parameters, tracking jitter, and GPS positioning improvement by scintillation mitigation

A method of determining spectral parameters p (slope of the phase PSD) and T (phase PSD at 1 Hz) and hence tracking error variance in a GPS receiver PLL from just amplitude and phase scintillation indices and an estimated value of the Fresnel frequency has been previously presented. Here this method is validated using 50 Hz GPS phase and amplitude data from high latitude receivers in northern Norway and Svalbard. This has been done both using (1) a Fresnel frequency estimated using the amplitude PSD (in order to check the accuracy of the method) and (2) a constant assumed value of Fresnel frequency for the data set, convenient for the situation when contemporaneous phase PSDs are not available. Both of the spectral parameters (p, T) calculated using this method are in quite good agreement with those obtained by direct measurements of the phase spectrum as are tracking jitter variances determined for GPS receiver PLLs using these values. For the Svalbard data set, a significant difference in the scintillation level observed on the paths from different satellites received simultaneously was noted. Then, it is shown that the accuracy of relative GPS positioning can be improved by use of the tracking jitter variance in weighting the measurements from each satellite used in the positioning estimation. This has significant advantages for scintillation mitigation, particularly since the method can be accomplished utilizing only time domain measurements thus obviating the need for the phase PSDs in order to extract the spectral parameters required for tracking jitter determination.

On the characterisation of electrically stressed polyethylene before and after chemical treatment

Low-density polyethylene (LDPE) was characterised for its dielectric and electrical properties before and after chemical treatment. A reduction in the permittivity and dielectric loss was observed in the polymer after treatment with hexane. The intensity in the Raman Spectrum in the disordered longitudinal acoustic mode region (DLAM) also was reduced due to a hexane treatment. Using thermally stimulated discharge current (TSDC) and laser-intensity-modulated method (LIMM) techniques it was observed that charge injection can be enhanced in the polymer matrix in the empty sites, created by the removal of the low molecular weight impurities with chemical treatment.

On the population biology of the mottled shore crab Pachygrapsus transversus (Gibbes, 1850) (Brachyura, Grapsidae) in a subtropical area

The mottled shore crab P. transversus is probably the most common brachyuran crab living in the marine rocky intertidal of southeastern Brazil. However, its biology is largely unknown. In this study, some aspects of the population biology of this species are investigated. Distribution of individuals in the intertidal range is heterogeneous. Sabellariid worm reefs and mytilid mussel beds can be considered as nursery grounds retaining most part of juveniles, while the rocky surface is mostly inhabited by adults, which find safety shelters in rock crevices. Annual size frequency distributions revealed clues of population stability and indicated that young individuals reach the adult habitat in a gradual process. Sex-ratio follows the 1:1 proportion in smaller size classes but is biased towards males in larger ones. Higher mortality in larger females is indicated as a possible cause of this pattern. Ovigerous ratio shows a remarkable seasonality in which highest percentages of ovigerous females occur during summer months, while recruitment of young is more intense from April to July, suggesting a very extensive larval development. Once established in the intertidal zone, young recruits will develop to mature individuals in late spring, when molting crabs become scarce and proportion of breeding females increases. Therefore, growth and reproduction are in a great part temporally separated, allowing an annual life cycle in which settlement, growth and breeding may take place within a I-yr period.

O conteúdo intelectual do lazer no processo do aprender a envelhecer

This qualitative study aimed to investigate the resonances of the intellectual content of leisure for older adults. A mixed questionnaire containing ten questions was applied to a sample of fifty older adults people of both genders. Data were descriptively analyzed by thematic content analysis technique and showed that such experiences encourage reflection and the exercise of citizenship. Among the intellectual contents to qualitatively fulfill free time availability were elected by the sample: watching news on TV (70%), videos on health and aging (55%), reading newspapers, magazines and books (54%), playing strategic games (35%) and visiting museums (8%). It can be concluded that the experiences sharpen the critical and intellectual creativity and subsidize better understanding of aging, involving the construction of knowledge and expanding the opportunities of learning to learn, to be, and to live.

On the stabilizing behavior of zirconia: A combined experimental and theoretical study

Reactive zirconia powder was synthesized by the complexation of zirconium metal from zirconium hydroxide using a solution of 8-hydroxiquinoline. The kinetics of zirconia crystallization was followed by X-ray diffraction, scanning electron microscopy and surface area measured by the nitrogen adsorption/desorption technique. The results indicated that zirconia with a surface area as high as 100 m(2)/g can be obtained by this method after calcination at 500degreesC. Zirconia presents three polymorphic phases (monoclinic, tetragonal and cubic), which are reversibly interconversible. The cluster model Zr4O8 and Z(r)4O(7)(+2) was used for a theoretical study of the stabilization process. The ab initio RHF method was employed with the Gaussian94 program and the total energies and the energy gap of the different phases were calculated and compared with the experimental energy gap. The theoretical results show good reproducibility of the energy gap for zirconia. (C) 2004 Kluwer Academic Publishers.
