A função autor e a crônica esportiva no Brasil: representações da Copa do Mundo em alguns jornais paulistas e cariocas

From the 1990s, Brazilian newspapers began to refer to the convening of different personalities to comment on the World Cup soccer in their sports pages. This article seeks to examine this phenomenon under the notion that the French philosopher Michel Foucault called the “author function” - one that establishes the existence, circulation and functioning of certain discourses within a specific audience.

Características da interface dos sites de notícias: um estudo do design e da usabilidade de jornais impressos e eletrônicos

The paper presents an ergonomic analysis of reading usability of electronic journals and the comparison with newspapers. As a method, it was adopted an evaluation of the user perception, from a printed questionnaire applied to a group of 41 people. Overall, the results indicate that on the analyzed newspapers there is need for greater care concerning the aspects of visual representation, involving more design application, usability, ergonomics, technology and communication.

Procedimentos metodológicos em design gráfico voltados a jornais diários impressos: estudos e relatos de experiência

This paper summarizes a research that has been developed from the concern about a company’s strategic planning, once regarding the product development process and its methodological guidelines. Our goal was to check if there is an ideal methodology, peculiar to the graphic design, which could be applied to a printed newspaper condition. And then, we could deduce, according to the design practices in newspapers, its relevance. We did not intend to create a specific graphic design methodology for daily newspapers, nor the analysis of methods, but we wanted to emphasize that the familiarization with acknowledged methods in the field of visual communication, during the process of professional formation, might ease good choices in the work practice on design. The understanding of the gradual introduction of graphic design on printed daily newspapers brings about, thus, not only their visual improvement, but also allows that this kind of journalism (which depends on a graphic interface in order to make their product come true) reconsider the newspaper as a whole.

Memórias da educação em astronomia no Brasil: recortes a partir das falas de pesquisadores entrevistados sobre o tema

This paper presents a historical retrospective concerning data from a research in Astronomy Education in Brazil, after 1973. It was organized on the basis of the speech analysis of national researchers considered references in this field by their peers. Furthermore, it was elaborated on the basis of other studies from the areas of Science Education, Physics and Astronomy. This historical overview was developed in order to facilitate understanding of the contexts in which the interviewed researchers have developed professionally. Moreover, we attempted to recover the memory of the growing field of research in Astronomy Education in the country. We believe that the history presented can help those trying to understand the past in an attempt to resolve current and future demands.

A representação temática da tecnologia nos jornais brasileiros e sua configuração mercadológica diante de uma perspectiva de conceito social

This article is part of the result of the Master's thesis of the author, guided by coauthor, and presents a theoretical and conceptual reflection on the representation of Technology in thematic sections Technology in four Brazilian newspaper sites. The fundamental hypothesis is that these editorials prioritize issues that meet market interests of companies in the sector and may be leaving out important social and cultural issues to the understanding of the relationship between technology and society. The study is itself oriented by prospects of journalistic theming and specialized journalism, from a quantitative analysis involving the websites from newspapers of Technology sections O Estado de S. Paulo, Folha de S. Paulo, Gazeta do Povo and Correio Braziliense. The study confirms the hypothesis that representation of Technology in newspapers is primarily the marketing, have not corresponding to an expectation of social and cultural concept. In addition, it is noticed that the editorial in question do not have specialized journalism characteristics, despite of potential generated by thematic segmentation.

Classificação climática de Thornthwaite e sua aplicabilidade agroclimatológica nos diferentes regimes de precipitação em Pernambuco

Knowing the annual climatic conditions is of great importance for appropriate planning in agriculture. However, the systems of climatic classification are not widely used in agricultural studies because of the wide range of scales in which they are used. A series with data from 20 years of observations from 45 climatological stations in all over the state of Pernambuco was used. The probability density function of the incomplete gamma distribution was used to evaluate the occurrence of dry, regular and rainy years. The monthly climatic water balance was estimated using the Thornthwaite and Mather method (1955), and based on those findings, the climatic classifications were performed using the Thornthwaite (1948) and Thornthwaite and Mather (1955) for each site. The method of Kriging interpolation was used for the spatialization of the results. The study classifications were very sensitive to the local reliefs, to the amount of rainfall, and to the temperatures of the regions resulting in a wide number of climatic types. The climatic classification system of Thornthwaite and Mather (1955) allowed efficient classification of climates and a clearer summary of the information provided. In so doing, it demonstrated its capability to determine agro climatic zones.

Discriminação de classes de cobertura vegetal utilizando técnicas de classificação digital de imagens de sensoriamento remoto

The aim of this work is to discriminate vegetation classes throught remote sensing images from the satellite CBERS-2, related to winter and summer seasons in the Campos Gerais region Paraná State, Brazil. The vegetation cover of the region presents different kinds of vegetations: summer and winter cultures, reforestation areas, natural areas and pasture. Supervised classification techniques like Maximum Likelihood Classifier (MLC) and Decision Tree were evaluated, considering a set of attributes from images, composed by bands of the CCD sensor (1, 2, 3, 4), vegetation indices (CTVI, DVI, GEMI, NDVI, SR, SAVI, TVI), mixture models (soil, shadow, vegetation) and the two first main components. The evaluation of the classifications accuracy was made using the classification error matrix and the kappa coefficient. It was defined a high discriminatory level during the classes definition, in order to allow separation of different kinds of winter and summer crops. The classification accuracy by decision tree was 94.5% and the kappa coefficient was 0.9389 for the scene 157/128. For the scene 158/127, the values were 88% and 0.8667, respectively. The classification accuracy by MLC was 84.86% and the kappa coefficient was 0.8099 for the scene 157/128. For the scene 158/127, the values were 77.90% and 0.7476, respectively. The results showed a better performance of the Decision Tree classifier than MLC, especially to the classes related to cultivated crops, indicating the use of the Decision Tree classifier to the vegetation cover mapping including different kinds of crops.
