NEWSPAPERS FOLHA DE SÃO PAULO E CORREIO BRAZILIENSE: WHAT THEY SAY ABOUT THE PROGRAM MORE DOCTORS?

Analyzes publications related More Medical Program from July to September of 2013 and its impact on Correio Braziliense and Folha de São Paulo. This is a descriptive study using a qualitative-quantitative methodology. The analyzed and related data represent what the program takes in print. 363 publications were found, 262 in Folha de São Paulo and 101 in Correio. The word "Doctor" appeared in more titles, and Folha de São Paulo were 110 negative titles; to Correio neutral character was in 50 publications. In the character of news, 178 of these are pessimistic. The "neutral" and 101 representing "optimistic" 83. Was found that the media is critical to the impact of the program, but the truth is not apparent, but the opinion of journalists who wrote the stories related to the theme.

Adubação nitrogenada em cultivares de arroz de terras altas

O objetivo deste trabalho foi avaliar a influência de diferentes doses de N em cobertura (0, 30, 60, 90 e 120 kg ha-1) sobre as características agronômicas de diferentes cultivares de arroz de terras altas (Caiapó, Primavera, Confiança, IAC 202 e Carisma) sob irrigação por aspersão durante os anos agrícolas 2003/04 e 2004/05, em área experimental da FCAV - UNESP - Jaboticabal (SP). Os cultivares Caiapó, IAC 202 e Carisma são os de maior produtividade, com o Primavera não respondendo ao incremento da adubação nitrogenada; o IAC 202 e Carisma são possuidores de índice de colheita mais elevado e responsivos ao nitrogênio aplicado em cobertura, sugerindo-se indicá-los para sistemas produtivos mais evoluídos; o cultivar Caiapó demonstra ser mais eficiente em absorver e utilizar o N contido no solo, sugerindo sua indicação para sistemas produtivos de menor aporte de tecnologia.

Perceptions of Amazonian deforestation in the British and Brazilian media

The Amazon rainforest stretches across more than six million square kilometers and nine countries. Of the original forest area it is thought that 18 per cent has been cleared, mainly for farming purposes. In Brazil, the main drivers of deforestation are beef ranching and soya production that together occupy more than 75 per cent of newly deforested land. The situation in the Amazon illustrates a fundamental dilemma facing environmentalists around the world: how to reconcile economic development with biodiversity conservation. In this paper the representation of this dilemma in the British and Brazilian news media is assessed. The results indicate that there were far more articles referring to deforestation in the Brazilian press (816 Brazilian to 29 UK) but that many of these make no mention of what factors are responsible for deforestation. The patterns of representation of the proximate (direct) causes of Amazonian deforestation were very similar in the two countries, with soya and beef cattle ranching commanding the most press attention. The ultimate (indirect) causes of deforestation, however, are treated very differently, with the Brazilian media seemingly far more aware of the role of economic development needs than the UK press. Interestingly, the role of international demand for soya, beef, and forest products in driving deforestation was highlighted primarily in the UK press. These findings are critically discussed in the context of media influence on public understandings of Amazonian deforestation.

Abundancia y distribución de la fauna íctica en la cuenca del río Suquía (Córdoba, Argentina)

En este trabajo se presenta la caracterización de los ensambles de peces de la cuenca del río Suquía. Los peces fueron recolectados, desde 1998 al 2002, en dieciséis sitios ubicados en los principales ríos dentro de la cuenca: arroyo San Francisco, río Cosquín, río Yuspe, río San Antonio y río Suquía. Se estimó la abundancia relativa de cada especie, riqueza, diversidad y dominancia en cada sitio estudiado. Se aplicó un Análisis Discriminante para determinar diferencias en la composición de las especies entre los ríos de la cuenca y antes y después de los principales centros urbanos. Veintiuna especies de peces fueron recolectadas en toda la cuenca, pertenecientes a doce familias y seis órdenes. Las especies mostraron diferentes patrones de variación. El Análisis Discriminante indicó marcadas diferencias de la ictiofauna entre los ríos. Si bien ellos compartieron un número elevado de especies, los patrones de abundancia de las mismas variaron entre sitios. Los resultados también demostraron el impacto negativo que ejerce la ciudad de Córdoba sobre los ensambles de peces. Este trabajo provee nuevos datos a cerca del estado de la ictiofauna del río Suquía y constituye un punto de partida que permitirá la aplicación de programas de monitoreo y evaluación con el fin de conocer la calidad de los recursos acuáticos.

Valores de transaminasas en cabras criollas infectadas con Trypanosoma vivax

La presente comunicación reporta los valores de las enzimas transaminasas, Aspartatoaminotransferasa (AST) y Alaninaaminotransferasa (ALT) encontrados en sueros de cabras infectadas con la cepa de Trypanosoma vivax Stock (TvIIV) y sus controles. Las determinaciones se realizaron durante un lapso experimental de diez semanas, divididos en dos períodos iguales (pre y post-infección) por intermedio de un método colorimétrico, utilizando kits comerciales. Los datos fueron analizados mediante la prueba t Student's. En el caso de la AST, la comparación de las medias parciales de ambos grupos infectado y control, no indicó diferencias estadísticas. Con respecto a la ALT, la contrastación de las medias parciales de pre y post-infección del grupo de cabras infectadas, señaló diferencias significativas (P<0,01).

Imagem pública e divulgação da química: desafios e oportunidades

Chemical knowledge plays a central role in the economical and social development of a nation. Chemistry is considered a key science, which provides the means and meanings that fuel the advancement of other fields of knowledge. However, the public image of chemistry is often associated with negative facts and misconceptions. This paper addresses and discusses the public image of chemistry with two case studies: the public image of chemistry depicted in two major Brazilian newspapers and the Brazilian project for the International Year of Chemistry (IYC). Analysis of the newspaper data strongly suggests that the public image of chemistry is related to both the way news is written and the ability of the reader to identify the chemical knowledge actually present in the text. Analysis of IYC related data in the second case study depicted an optimistic panorama for the divulgation of chemistry at both national and local levels. A model for broad and effective initiatives for dissemination of chemistry is discussed. The need to keep science divulgation as the top agenda of the scientific community is also highlighted.

Incidence of type 1 diabetes mellitus in Passo Fundo, RS, Brazil

To establish the incidence of type 1 diabetes among children (infants to 14 years of age) in the city of Passo Fundo, Rio Grande do Sul, Brazil (population under 15 years = 50,098), during the period of January to December 1996, a retrospective and prospective population-based registry was established, using physician reports of newly diagnosed patients under 15 years of age with type 1 diabetes as the primary source of case identification. Primary and nursery schools and a general call through the media (newspapers, radio and television) was the secondary source. Data were calculated according to the methods recommended by the WHO (1990). Six new cases were identified. Case ascertainment was estimated at 100%. The incidence of type 1 diabetes in the year 1996 was 12/100,000 inhabitants. These data indicate that the incidence of childhood type 1 diabetes in a subtropical region in the Southern part of Brazil was similar to that observed in developed countries throughout the world. The inability to demonstrate the North-South gradient is probably due to the European origin of inhabitants of the city.
