Educação e economia solidária: contribuições da pedagogia da alternância para a formação dos catadores de materiais recicláveis

This text presents the Pedagogy of Alternating methodology, highlighting its contribution to re-think the formation of catadores of recycling materials (rubbish collectors). Whereas the use of this approach in the urban area is unusual, the goal of the article is to initiate a debate to promote further elaborations. Initially an overview of the Pedagogy of Alternating is presented and the main instruments used in this approach are commented. Two theoretical and methodological issues are indicated as challenges for catadores formation: the relations between Education and Work and the relations between Theory and Practice. The need to overcome dichotomy between these dimensions of human activity (that predominates in today's society) is defended. The catadores work reveals the exclusion of these workers of less organized sectors of production chains, with few opportunities to obtain better income and qualification. Overcome this gap requires an intense training to turn the catadores in recycling workers . To reach this goal the implementation of Alternating experiences between study and work in cooperatives and schools is not enough. A deep transformation is needed over the ways and subjects of both study and work, in order to create emancipating activities that promotes a full development of these workers.

Considerações sobre sessões de Teletandem como gênero discursivo: breve estudo e exemplificação

The reflex of social and cultural changes in discursive practices can indicate that language has a fundamental role in transforming the society and attempts of defining the directions of changes must include new forms of language practices. One of these forms concerns to computer media in teaching-learning process, showing how technology and culture interact in a significant way to interfere in language uses. In this context, it has been developed in UNESP/Assis linked to the Center for Language and Teacher Development the project Teletandem Brasil: Foreign Languages for All as a new practice of language teachinglearning through technological resources. The present paper aims to present a description of the teletandem sessions as a discursive gender according to the Bakhtin’s gender theory. The data was collected during the second semester of 2010, in sessions of interaction with an American university. The considerations are directed by the following questions: (a) how are the statements of a session discursively organized; (b) what kind of relationship the partners have with their mother language when they teach it as a foreign language, in this context. The analysis allowed us to conclude that: (a) the sessions can characterize a hybrid and secondary gender in this specific area of human activity, even the partners still find difficulties in this gender domain; (b) the teletandem sessions constitute an important instrument for the critical language awareness between the partners.

O ensino de Português Língua Estrangeira no contexto virtual do Teletandem: aspectos linguístico-discursivos

The project Teletandem, linked to the Centro de Línguas e Desenvolvimento de Professores UNESP/Assis, promotes the interaction between undergraduates students in Languages and undergraduates students from foreign universities in order to promote the teaching of Portuguese for those who do not speak Portuguese and give an opportunity to Brazilian students to learn a foreign language. Therefore there is a different context that can result in new forms of statements produced in this specific area of human activity. The present paper aims to present a description of Teletandem sessions as a discursive gender according to the gender theory, showing the multiplicity of discursive genders that emerge during an interaction. We also intend to verify the levels of Critical Language Awareness among Brazilian participants according to the Critical Discourse Analysis.

The endangered species Brycon orbignyanus: genetic analysis and definition of priority areas for conservation

Currently, biodiversity is threatened by several factors often associated with human population growth and the extension of areas occupied by human activity. In particular, freshwater fish fauna is affected by overfishing, deforestation, water pollution, introduction of exotic species and habitat fragmentation promoted by hydroelectric dams, among other environmental impact factors. Several action plans to preserve ichthyofauna biodiversity have been adopted; however, these plans frequently cover only a small number of species, and decisions are often made without strong scientific support. This study aimed to evaluate the genetic aspects of wild groups of Brycon orbignyanus, an endangered fish species, using microsatellites and D-loop regions to identify the genetic structure of the samples and to establish priority areas for conservation based on the genetic patterns of this species. The results indicated that the samples showed levels of genetic variability compatible with others studies with Neotropical fishes. However, the results obtained in the analysis of molecular variance (AMOVA) for microsatellites (F (ST) = 0.258) and D-loop (F (ST) = 0.234) and the interpopulation fixation index revealed that B. orbignyanus was structured in different subpopulations in the La Plata River basin; the areas with better environmental conditions also showed subgroups with higher rates of genetic variability. Future conservation actions addressing these sites should consider two different management units: the complex formed by the Ivinhema River, Upper Parana, Camargo Port and Ilha Grande groups; and the complex formed by the Verde River and Sucuriu River groups.

Adsorção de cádmio em Latossolos sob vegetação de mata nativa e cultivados

Heavy metals are found naturally in soils at low concentrations, but their content may be increased by human activity, making them one of the barriers in management of tropical soils. These chemical elements can be found in the composition of organic and inorganic fertilizers, insecticides, fungicides, mine tailings, and urban waste, and may cause serious damage to the environment and human health. Thus, adsorption studies are essential in assessing the behavior of heavy metals in the soil. The objective of this study was to evaluate the influence of soil chemical, particle size, and mineralogical properties on adsorption of cadmium (Cd), evaluated by Langmuir and Freundlich models, in Latossolos (Oxisols) with or without human activity. Soil samples were collected from the surface layer, 0.00-0.20 m, and chemical, particle size, and mineralogical analyzes were performed. In the adsorption study, concentrations of 0, 5, 25, 50, 100, 200, 300, and 400 mu g L-1 of Cd were used in the form of Cd(NO3)(2). The empirical mathematical models of Langmuir and Freundlich were used for construction of adsorption isotherms. Data were analyzed by means of multivariate statistical techniques, Cluster Analysis and Principal Component Analysis. The data from the adsorption experiment showed a good fit to the Langmuir and Freundlich models. Soils with a lower goethite/hematite ratio and greater cation exchange capacity and pH, showed higher maximum adsorption capacity of Cd.

Caracterização do uso da terra em diferentes épocas na bacia hidrográfica do ribeirão paraíso- são manuel sp, por meio de sistemas de informações geográficas

This study aimed to evaluate a period of 38 years, the use and soil occupation of the Paradise River watershed, inserted in the citys of São Manuel and Areiópolis-SP using aerial photographs for the year 1972 and TM image (Thematic Mapper) obtained by the Landsat-5 satellite, in 2010, using geoprocessing techniques. The watershed in question is very important for the city of São Manuel-SP, because its urban area is inserted in its divisors which part of it belongs to the Environmental Protection Area (APA) Perimeter Botucatu-SP, considered a recharge area of the aquifer Guarani. Today, the development of agriculture faces challenges, which is to produce more food without impacting the environment. Allied to this concern, research institutions have sought new technologies that allow the detection and quantification of human actions, enabling interventions in order to minimize possible damage to the environment. Among these technologies can be cited Geographic Information Systems (GIS), which a large volume of data and information stored in a region at different times can be evaluated in the same time, suggesting different approaches to the planning of land use. The results of the mapping of areas of use and soil occupation result nine classes in 1972, and the coffee culture showed the biggest occupation (37.94%) of the total area. The 2010 mapping formulated twelve classes of use, which demonstrated the predominance of sugar cane (37.94%), on the areas occupied by coffee and pasture before. The land use maps of 1972 and 2010 showed results that show intense human activity in the modification of natural landscape.

Potencial de contribuição e importância socioambiental dos 'catadores autônomos' de Rio Claro (SP) para o programa de coleta seletiva municipal

The Urban Solid Residues are the rests of human activity, popularly known by trash and considered by population like useless, undesirable and disposable. On the other hand, for the waste pickers, solid residues are the beginning of a cycle: they see in the other's people trash the only income, an economic value. Currently, in brazilian cities, one million collectors act, alone or in cooperatives, socially excluded by the work they do. The National Policy of Solid Residues (PNRS), instituted in 2010, established guidelines to the execution of integrated residues management, with should be practiced by city halls and other governmental institutions. This policy has, besides other things, goals of residues reduction and inclusion of waste pickers in the mechanism of selective collect and recycling. However, this and other public policies created for residue management are benefic only for cooperated waste pickers. That could negatively affect most of this class, since 90% are waste pickers working in a precarious way on the country's streets. This study has for objective show that most of waste pickers that work in a precarious way on the brazilian territory has a huge potential for the solid residues recycling chain and how they should be valued for the environmental services they provide, so they can be included with dignity on the society, ensuring economic and social benefits for this workers. The methodology adopted was based on the amount of residue collected by the 44 cooperated members of the Rio Claro‟s waste pickers cooperative to estimate the potential of collect and recycling did by 210 autonomous waste pickers who are active on city streets. It was observed that the cooperative collects the equivalent of 10.2% of all recyclable residues generated by city population. However, with the potential that these autonomous waste pickers have, which together could contribute 465 tonnes of solid residues per month, or 5,570 tons a year...
