Cobertura sobre Terceira Idade na imprensa brasileira

This article intends to inventory the medias that also cover Third Age in Brazil, in view of that all the demographic pointers reveal the accented process of aging of the worldwide population, and therefore of our country. A time that the journalists cannot ignore the changes that occur in the interior of the society, in which it is the main area of performance of the journalism, we want to understand why the Brazilian media still dedicates so little space to this phenomenon of the elderly, in contrast of what occurs in other countries. We ask ourselves, then, if the change in the way of looking at the elderly one would not have to be born inside of the University, through the young who prepare for the exercise of the profession, with citizenship and social concern. In the Course of Journalism of the UNESP/Bauru a group of future journalists is searching this subject, for this they sign this article.

Análise temporal da cobertura do solo na zona de amortecimento de reserva biológica

The Municipal Biological Reserve of Serra do Japi shelters an important forest remnant of Atlantic Rainforest in the state of São Paulo. For its ecological importance, were created instruments for environmental and territorial management of the Conservation Unit, with the regulation of the use and occupation of the land in its Buffer Zone (BZ) in 2004. The objective of this study was to analyze the evolution of the land cover in the BZ region of the Municipal Biological Reserve of Serra do Japi in Jundiaí-SP, between 1989 and 2010. It was used in this study the image analysis of the satellite LANDSAT-TM5, with the help of software ILWIS and IDRISI. The results showed that urban occupation has increased 37.47% and the agro pastoral and reforestation areas have decreased 36.62% and 72.22% respectively, while forest areas have increased 49.57%. However, the relative importance of the forest area in BZ ranged from 46.60% in 1989 to 69.71% in 2010, leading to the conclusion that this region was favored by changes in land cover in the period evaluated, despite strong pressure for urban expansion in its surroundings.

A criminalização das manifestações de junho de 2013 na cobertura jornalística impressa de O Estado de S. Paulo

Essa monografia tem por objetivo verificar se a cobertura jornalística impressa do jornal O Estado de S. Paulo atuou como instrumento de criminalização das manifestações de junho de 2013, observada a precária atuação da mídia tradicional que ora desmoralizou os protestos, ora deslocou o eixo das discussões das demandas sociais e fatores políticos para o modo de agir dos manifestantes. Busca-se compreender, mais amplamente, a criminalização dos movimentos sociais pela mídia, fenômeno já notado por autores como Batista (2014), Bortolozzi Júnior (2008), Adissi (2011), Martins (2007) e Foscarini (2014), bem como sumarizar os mecanismos e conceitos que podem contribuir para o entendimento do assunto

Desempenho de discos de corte de semeadora-adubadora em diferentes quantidades de cobertura vegetal

The quality and efficiency in straw cutting are determinants in the sowing process, according to the occurrence of "tamp" and stops, the magnitude of the straw removal or even the known effects of the seed "envelopment" where the cutting mechanism can not cut the remaining straw. Thus, the objective of this study was to evaluate the performance of different mechanisms for straw cutting of a seeder individualized in different amounts of crop coverage artificially added in a clay soil. The experiment was conducted at Unesp – Sao Paulo State University in the Experimental Farm Lageado, belonging to the College of Agricultural Sciences - Unesp, Botucatu. The experimental design was split plot with four replications, with main plots consisting of five quantities of black oat straw, in area with no-tillage system and subplots of three opening furrows mechanisms, which are: plane disk (PD), corrugated disk (CD) and wavy disk (WD). The wavy disk provided greater rolling resistance, reducing the speed of the set (tractor and equipment). The plane cutting disk showed the highest values of mobilized soil area, deeper penetration into the soil, requiring lower values of vertical force and higher values of lateral force. Regarding the type of waste and doses used, they offered no resistance to cutting and there was no change in the horizontal force on straw.

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.

Mobilização do solo, velocidade de infiltração de água e taxa de cobertura do solo na grama esmeralda, sob manejos mecanizados

The excessive compaction of the soil observed in sod production systems, affects the physical attributes of the soil, which can influence the water infiltration into the soil and hence the rate of soil cover by turfgrasses and time of the sod production. To minimize the effects of soil compacting, some producers use soil preparation equipment that raises the soil on the surface but does not cause excessive roughness which may harm the quality of the sod. Thus, the aim of the present study was to evaluate the infiltration rate and soil cover rate due to different management mechanized in the zoysiagrass sod production. The experimental design had random plots and four replications. The treatments consisted of five mechanized managements of soil: witness (without the use of equipment); coulter blade disc harrow used once (1CB), coulter blade disc harrow used twice (2CB), surface chisel used once (1C), surface chisel and coulter blade disc harrow used once (1C + 1CB). The treatments with 2CB and 1C + 1CB provided greater basic water infiltration speed in the soil and higher rate of soil cover by the turfgrass. The rate of soil cover by turfgrass is positively correlated with water infiltration rate at 133 and 226 DAP, demonstrating the influence of managements used in zoysiagrass sod production and the increment in the infiltration rate of water. Soil preparation utilizing coulter blade disc harrow used twice or surface chisel and coulter blade disc harrow used once is recommended under the conditions this study was done.

Análise do índice de cobertura vegetal da área urbana de Piratininga (SP)

The urban area is now home to 50% of world population and the activities related to their disorganized growth, promote the formation of an unhealthy environment. The urban vegetation is necessary and beneficial, because in addition to bringing the man of nature, mitigates climate change and improve the urban microclimate. This study aimed at surveying and analyzing the rate of existing vegetation in urban Piratininga - SP, and from the data obtained, provide allowance for management and planning of green areas and urban areas. Data came from sample survey conducted in 2007 and computerized survey conducted in 2010 indicated that many new neighborhoods have low opt for planting trees of small to medium which does not enhance the urban environment requiring an environmental planning.
