Environmental news: coverage of the Earth Summit by Brazilian newspapers

This article examines how two important Brazilian newspapers (Floha de S. Paulo and O Globo) covered the UN Conference on Environment and Development (UNCED) or Earth Summit. The analysis will also determine the characteristics of the environmental media and its significance when it comes to coverage of environmental issues. This article provides historical background information on the environmental media in the US and in Brazil, contextual information on the Earth Summit, a content analysis of stories about UNCED published by the two Brazilian newspapers. Overall, 649 news items were used to determine the type of sources used, as well as the kind of issues covered. The analysis showed that government officials were the most frequently cited sources, while environmentalists and scientists were all but ignored as news sources. The analysis also indicated that economic issues were surprisingly prominent in the coverage. These results are compatible with the previous studies done in several countries and indicate that environmental media are still extremely reliant on "official" voices. The finding also highlight the fact that the range of issues covered by the environmental media largely reflects the perceived public agenda.     

Argentina and the 1984 Los Angeles Olympics

The election of Raúl Alfonsín in October of 1983 represented the return of democracy to Argentina after more than seven years of a military dictatorship that left the country in a terribly distressed state. Since the dictatorship had joined the boycott of the 1980 Moscow Olympics led by the USA, for Argentina, the 1984 Los Angeles Olympics meant both coming back to the Olympic fold and the first such festival under the new democratic government. This paper explores Argentina's trajectory towards, and construction of, its participation in the country's first post-dictatorship Olympics. In doing so, this paper reveals why participation in the 1984 Los Angeles Olympics was not a priority for the incoming administration and why such participation was not conceived as a potential emissary capable of reaffirming on the global Olympic stage the hard fought, yet still emerging, democracy of Argentina. In addition, it reveals not only the determination of the Alfonsín administration to make his sport policy work but also its aspirations, complexity and ambiguities.     

Red pigment production by Penicillium purpurogenum GH2 is influenced by pH and temperature

The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture of Penicillium purpurogenum GH2, using Czapek-Dox media with d-xylose as a carbon source. An experimental design with a factorial fix was used: three pH values (5, 7, and 9) and two temperature levels (24 and 34 °C) were evaluated. The highest production of red pigment (2.46 g/L) was reached with a pH value of 5 and a temperature of 24 °C. Biomass and red pigment production were not directly associated. This study demonstrates that P. purpurogenum GH2 produces a pigment of potential interest to the food industry. It also shows the feasibility of producing and obtaining natural water-soluble pigments for potential use in food industries. A strong combined effect (p<0.05) of pH and temperature was associated with maximal red pigment production (2.46 g/L).     

The academic writing process in Spanish universities: perceptions of students and faculty / El proceso de escritura académica en la universidad española: percepciones de estudiantes y profesores

Abstract

This paper is intended as an exploration of university faculty and students’ perceptions of a number of dimensions involved in the written composition of academic texts. We analysed the responses to scale 3 in the European Writing Survey (EUWRIT) (in its Spanish version: Encuesta Europea sobre la Escritura Académica, EEEA) by a group of social science and humanities students (n = 1,030) and faculty (n = 230) from nine Spanish universities. We then examined the similarities and differences in their perceptions and established a factorial structure of the different dimensions underlying the writing process. The data indicate that both groups concur in the value assigned to both changing ideas in the course of the composition process (although this process seems to be understood differently by each group) and the revision and feedback processes. The students, however, claim to be involved in more planning and previous reading activities than the teachers perceive them to be. The significance of these results for a process-oriented perspective in academic writing is discussed.
