Good Practices in Strategic Environmental Assessment Processes under the Brazilian Practitioners’ Vision  [PDF]
Antonio W. L. da Silva, Marinilse Netto, Paulo Selig, Alexandre Lerípio
Journal of Environmental Protection (JEP) , 2018, DOI: 10.4236/jep.2018.96045
Abstract: The use of good practices (GP) can improve the technical quality and, as a consequence, the outcome of the Strategic Environmental Assessment (SEA) process, increasing its effectiveness. This study aimed to present GP pointed out by Brazilian practitioners (members of the SEA development teams) from the perspective afforded by their participation in processes of this tool. The data were collected through personal interviews with 11 professionals responsible for preparing a total of 17 SEAs, who were asked about what measures adopted in the SEA could be considered BP. The responses were audio-recorded, transcribed, and had their content assessed by Content Analysis technique. Nine GP were highlighted by practitioners. The GP indicated represent a valuable contribution to the improvement of future use of SEA, either in Brazil or in other countries, because they are the result of consolidated experience in real cases of application of the tool.
A vontade segundo Jacotot e o desejo de cada um
Netto, M?nica Costa;
Educa??o & Sociedade , 2003, DOI: 10.1590/S0101-73302003000100018
Abstract: this paper describes the experience of working with jacques ranciere's the ignorant schoolmaster in a continuing education course for adult educators in the state of rio de janeiro during the second semester of 2002. the question of the will involved in the act of learning is discussed. it draws from course participants' reactions to the principles of emancipatory education as elaborated by joseph jacotot (france, 19th century), which are presented in ranciere's book.
Oxidative stress response in sugarcane
Soares Netto, Luis Eduardo;
Genetics and Molecular Biology , 2001, DOI: 10.1590/S1415-47572001000100014
Abstract: oxidative stress response in plants is still poorly understood in comparison with the correspondent phenomenon in bacteria, yeast and mammals. for instance, nitric oxide is assumed to play various roles in plants although no nitric oxide synthase gene has yet been isolated. this research reports the results of a search of the sugarcane expressed sequence tag (sucest) database for homologous sequences involved in the oxidative stress response. i have not found any gene similar to nitric oxide synthase in the sucest database although an alternative pathway for nitric oxide synthesis was proposed. i have also found several genes involved in antioxidant defense, e.g. metal chelators, low molecular weight compounds, antioxidant enzymes and repair systems. ascorbate (vitamin c) is a key antioxidant in plants because it reaches high concentrations in cells and is a substrate for ascorbate peroxidase, an enzyme that i found in different isoforms in the sucest database. i also found many enzymes involved in the biosynthesis of low molecular weight antioxidants, which may be potential targets for genetic manipulation. the engineering of plants for increased vitamin c and e production may lead to improvements in the nutritional value and stress tolerance of sugarcane. the components of the antioxidant defense system interact and their synthesis is probably closely regulated. transcription factors involved in regulation of the oxidative stress response in bacteria, yeast and mammals differ considerably among themselves and when i used them to search the sucest database only genes with weak similarities were found, suggesting that these transcription regulators are not very conserved. the involvement of reactive oxygen species and antioxidants in plant defense against pathogens is also discussed.
A vida infantil e sua intimidade pública: o trabalho social como novidade na aten??o à infancia na América Latina, 1928-1948
Nunes, Eduardo Silveira Netto;
História, Ciências, Saúde-Manguinhos , 2012, DOI: 10.1590/S0104-59702012000200006
Abstract: the professionalization of attention to the needs of children, which has taken place during the course of the twentieth century in areas such as health, education, law and social assistance, underwent an important conceptual development in the first decades of the twentieth century. in the field of social assistance, the structuring of the area of social services marked the introduction of a new variable in formulating policies and practices towards children. this article examines how the subject of social services was discussed, in the context of the american continent, at the pan american child congresses which took place between 1928 and 1948, when its development was proposed as a new tool for social policies, especially for those directed towards children.
Filosofía del turismo: Una propuesta epistemológica
Panosso Netto,Alexandre;
Estudios y perspectivas en turismo , 2007,
Abstract: this article proposes a study of tourism philosophy, through the theory of paradigms proposed by thomas kuhn and so it is an advance to the epistemological studies of the phenomenon. the importance of this is study is the fact that there is a lack of epistemological studies on the scientific production of tourism, fact that debilitates this area of study. to help in the comprehension of the theoretical studies in tourism we propose a new division of the tourism theories
Amoniza??o de superfosfato simples
Cobra Netto, A.;
Anais da Escola Superior de Agricultura Luiz de Queiroz , 1977, DOI: 10.1590/S0071-12761977000100036
Abstract: ordinary superphosphate run through 20 - 40 - 60 - 100 and plus mesh sieves were treated with 3 per cent (weight basis) of anhydrous ammonia in special aparattus. this amount reacting with normal superphosphate caused reversion in water soluble phosphate. the rate of ammoniation varied from 2,7 to 3,8% per unit of p2o5 considering the fraction before the treatment. the reversion range was from 44,6 to 57,9% of water soluble phosphate. the rate of correlation between solubility and ammonia dosis was -0,96 and the linear regression obtained was y = 24,344-4,732x.
Sobre a no??o de ?mundo? nos discursos culturais contemporaneos: rela??es entre universal e diversidade
Nicolau Netto,Michel;
Análise Social , 2011,
Abstract: considering the notion of world as a socio-historical category, this article analyses how it is perceived in the contemporary time, from the perspective of the relation between the ideas of universal and diversity. if until the second half of the twentieth century the images men had about the world were based on the idea of universal, today it is the idea of diversity which predominates on this definition. we take as our corpus of research the arts and the music, and conclude that if the idea of diversity assumes such predominance, a global market imposes on it its universal rules.
Feeding ecology of the Green-cheeked parakeet (Pyrrhura molinae) in dry forests in western Brazil
Ragusa-Netto, J.;
Brazilian Journal of Biology , 2007, DOI: 10.1590/S1519-69842007000200009
Abstract: the genus pyrrhura includes small to medium-sized parakeets, which inhabit both low and dry alongside tall rainforests, mainly in south america. pyrrhura molinae is still common, year round, in the markedly seasonal forests of western brazil. this parakeet, as well as most neotropical parrots, continues to be poorly understood. hence, in the present study i examined their foraging ecology both in a highly deciduous and in a semi-deciduous forest in western brazil. in addition, i assessed the relationship between food resource production (flowers and fruits), and the diet of this parakeet. pyrrhura molinae exhibited a flexible diet consisting of 16 tree species, from which it consumed flowers (three species), seeds (three species), fruit pulp or aril (four species), and both pulp and seeds (six species). parakeets consumed a wide array of fleshy fruits in the semi-deciduous forest, especially cecropia pachystachya catkins. conversely, in the highly deciduous forest they extensively foraged for figs (70% of the diet), in addition to nectar and seeds from dry fruits. ficus calyptroceras, besides being abundant, bore fruits year round, and was substantially used by parakeets every month. potentially, by exploiting a diverse set of plant food resources, and particularly due to the substantial use of figs, asynchronously produced, pyrrhura molinae persists during the long dry season in the markedly seasonal forests of western brazil.
Abundance and frugivory of the toco toucan (Ramphastos toco) in a gallery forest in Brazil's Southern Pantanal
Ragusa-Netto, J.;
Brazilian Journal of Biology , 2006, DOI: 10.1590/S1519-69842006000100017
Abstract: unlike other toucan species, the toco toucan (ramphastos toco) - the largest ramphastidae - usually inhabits dry semi-open areas. this conspicuous canopy frugivore uses a large home range that includes a variety of vegetation types, among which gallery forests are widely cited as important to this species. however, the factors relating to the occurrence of toco toucans in such habitats are unclear. i studied the abundance of toco toucans as well as the availability of fleshy fruit in a gallery forest in the southern pantanal (sub-region of miranda, brazil), in order to assess the relationship between these parameters. also, i examined toucan foraging activity to analyze its relationship with both toucan abundance and fruit availability. the presence of the toco toucan was more common in the gallery forest from the middle to the end of the dry season and during the middle of the wet season. toucans foraged for fleshy fruits, mainly genipa americana, ficus luschnatiana, and cecropia pachystachya fruits, feeding mostly on g. americana (by far the favorite food resource) and f. luschnatiana fruits during the dry season, while c. pachystachya fruits were important in the wet season. toco toucans foraged particularly heavily (> 80% of foraging activity) on g. americana fruits during the latter part of the dry season, when fleshy fruit availability declined sharply. toco toucan abundance in the gallery forest was associated with the availability of the most commonly consumed fleshy fruits, and also with its foraging activity. this finding suggests that the toco toucan moved to the gallery forest periodically in response to the availability of abundant food resources, especially the g. americana fruits widely available and exploited during the severely dry season. therefore, these fruits potentially contribute to toco toucan persistence in the south pantanal during the harshest period of the year.
Fruiting phenology and consumption by birds in Ficus calyptroceras (Miq.) Miq. (Moraceae)
Brazilian Journal of Biology , 2002, DOI: 10.1590/S1519-69842002000200018
Abstract: figs are a remarkable food resource to frugivores, mainly in periods of general fruit scarcity. ficus calyptroceras miq. (moraceae) is the only fig species in a type of dry forest in western brazil. in this study i examined the fruiting pattern as well as fig consumption by birds in f. calyptroceras. although rainfall was highly seasonal, fruiting was aseasonal, since the monthly proportion of fruiting trees ranged from 4% to 14% (n = 50 trees). i recorded 22 bird species feeding on figs. in the wet season 20 bird species ate figs, while in the dry season 13 did. parrots were the most important consumers. this group removed 72% and 40% of the figs consumed in the wet and dry seasons, respectively. no bird species increases fig consumption from dry to wet season. however, a group of bird species assumed as seed dispersers largely increases fig consumption from wet to dry season, suggesting the importance of this resource in the period of fruit scarcity. the results of this study points out the remarkable role that f. calyptroceras plays to frugivorous birds, in such a dry forest, since its fruits were widely consumed and were available all year round.
