A mineração artesanal e de pequena escala em pegmatitos e cerâmica no município de Parelhas, região do Seridó/Rio Grande do Norte

The working conditions, occupational health, occupational illness and workers quality of life, usually referring to the artisanal activities and the workers with a poor professional support. Because this reality is still present in locals without good infrastructure of social and economic attention, there is a need for a broad knowledge of problems related to the productive processes that include features of unsanitary and unhealthy. Despite the intense process of industrialization promoted by globalization and the growth of developing nations like Brazil, the activities of artisanal and small-scale mining are still suffering from the marginalization of their production processes and their workers. This dissertation deals with the description of mineral-based activities (MBA), especially the activities related to production processes of extraction and processing of red pottery and minerals in pegmatites in Parelhas city, Seridó, Rio Grande do Norte, which are conducted by small mining companies or artisanal miners. The study of the work process was based on direct observation, photographic documentation, ergonomics, health and occupational safety analysis, interviews and structured questionnaire with workers of the two activities. The results indicate the need for improvement in both workplaces (red pottery and pegmatites), adaptation of workers to safety standards specific to the workplace, more attention and care related to ergonomics and occupational safety, greater importance to economic and social relations among performed activities, workers and firms of mineral branch and better and greater integration of social policies, supported by different sectors of society with the intention of transforming the current social, cultural, labor and education situation

A pesca de pequena escala no rio Madeira pelos desembarques ocorridos em Manicoré (Estado do Amazonas), Brasil

O trabalho teve como objetivo analisar o desembarque da pesca comercial na região do Médio rio Madeira, tendo como área focal o município de Manicoré, buscando identificar as espécies explotadas, os locais de pesca e sua contribuição para o abastecimento local de pescado. O desembarque foi amostrado diariamente, utilizando questionários aplicados aos pescadores após a comercialização do pescado. Foram desembarcadas no ano de 2002 aproximadamente 225,4 toneladas de pescado. Canoas motorizadas efetuaram mais expedições de pesca, entretanto os barcos de pesca desembarcaram uma maior produção. Os valores médios de desembarque foram de 11,2; 5,4 e 2,4 toneladas por mês para barcos, canoas e compradores de pescado respectivamente, sendo as capturas compostas por 32 espécies ou grupo de espécies, sendo jaraqui (Semaprochilodus spp), pacu (Mylossoma duriventre), curimatá (Prochilodus nigricans), sardinha (Triportheus spp) e jatuarana (Brycon spp), responsáveis por 75% do pescado desembarcado. Foram identificados 32 locais de pesca, sendo os mais explotados os rios Madeira e Manicoré, os lagos Acará e Boquerão e o igarapé Matupiri.

Contratações Públicas no Setor de Resíduos Sólidos: Um estudo sobre as formas de contratação, delegação e gestão das atividades econômicas e serviços públicos relacionados ao setor de resíduos sólidos

Existem diversas formas no ordenamento jurídico brasileiro mediante as quais o poder público pode contratar, delegar ou gerir a prestação de serviços que envolvam entes privados. São elas os contratos de mera prestação de serviços regidos pela Lei 8.666/93 ou pela Lei 10.520/02; os convênios; as concessões comuns de serviço público regidas pela Lei nº 8.987/95; as parcerias público-privadas tuteladas pela Lei 11.079/04 e os consórcios públicos regidos pela Lei nº 11.107/05. O presente trabalho visa explorar como as contratações públicas ocorrem no setor de resíduos sólidos. Para isso, em um primeiro momento foi analisada a natureza jurídica dos serviços relacionados ao manejo de resíduos. Em um segundo momento, foi traçado um panorama sobre as modelagens contratuais disponíveis ao poder público para realizar essas contratações, bem como os possíveis problemas levantados pela doutrina no uso desses moldes. Por último, foram analisados casos concretos com o fim de averiguar se os referidos problemas são levados em consideração pelo Administrador Público ao elaborar os editais e contratos para prestação desses serviços pela iniciativa privada.

Sistema de recirculação e rotina de manejo para larvicultura de camarões de água doce Macrobrachium rosenbergii em pequena escala

A recirculating system and a matching management schedule for small-scale freshwater prawn larviculture were described. The system comprised a 140 L larval culture tank in line with a 43 L biofilter filled with 24 L of calcareous substrate. Both the tank and biofilter were made of black colored fiberglass in a conical-cylindrical shape. The turnover rate of the water through the system was 24 times a day; water was pumped by airlift. Results of ten larvicultures showed that the system maintained temperature, dissolved oxygen, pH, salinity, ammonium and nitrite stable and suitable to Macrobrachium rosenbergii larvae. Survival and productivity varied from 60.5 to 72.4% and 37 to 72 post-larvae/L, respectively; both were compatible with results of commercial hatcheries. Therefore, this system may be very useful for research purposes or adapted for small-scale post-larvae production.

Fatores de decisão da adoção do gás natural na geração de energia elétrica em pequena escala em postos de combustíveis: um estudo de anális de decusão usando o processo de hierarquia analítica AHP

A modeling of criterias and alternatives is through and applied a questionnaire based on method AHP to proprietors of gas stations. The considered alternatives had been the maintenance of the current state with electric energy of the deliverer and the generation in small scale based on the natural gas. The used criteria had been Cost of the Investment, Final Cost of the Energy, Operational cost, Ambient Benefits, Risk and Variation of Costs. The study it was carried through in the city of Natal, RN in ranks that make use of the natural as for resale, where the generation alternative on the basis of the available gas is present. The main results evidence in a dimension the viability of use of method AHP with questionnaire by means of validation of the judgments with analysis of variance beyond proper the normal mechanisms of analysis of consistency to the method. The main results of the analysis help to show that in this in case that the profile of models of criteria and judgments of the actors is similar, with the final evidence of that it has a dominance of the maintenance of the energy of the deliverer. The main criterion to influence this decision was the risk

Distribuição espacial em pequena escala de um anfípode exótico em fragmento florestal e plantio de espécies nativas

Anthropogenic interferences in natural environments cause the breakage of spatial and competitive barriers, which may infuence the spatial distribution of species. In this study, we describe the spatial distribution of an exotic amphipod, Talitroides topitotum, in two distinct sites, a forest fragment and a plantation of native arboreal species. We analyzed possible variations in this spatial distribution in different periods of the year and verifed whether the vegetation cover and the litter layer depth may explain the distribution pattern of this species. We performed analyses of frequency distribution to determine the pattern of this species spatial distribution, as well as correlation tests to determine the effect of these two variables of habitat structure. The spatial distribution analysis revealed that T. topitotum presents aggregated distribution in both areas, indicating that this species has low environmental demands or that both areas are below a minimum environmental quality threshold. However, even with this similarity, the population in the fragmented site presented a higher index of aggregation when compared with the population of the plantation site. Corroborating previous studies, there was a negative correlation between abundance of T. topitotum and litter layer depth in the plantation site. Studies on invaded habitats can help understand how invasive species occupy new environments and the factors that can infuence their spatial distribution.

Limites e possibilidades para a dinamização das atividades econômicas em assentamentos da reforma agrária no Estado de São Paulo

This paper provides an overview of the key findings of a survey that sought to examine the relationship between local government agencies and agrarian reform communities in the State of São Paulo, particularly with regard to the types of support that have been provided by these agencies to the economic activities of settlements. The research was part of the project "The agencies and services involved in the implementation of public policies for equity and growth", which was supported by the Instituto de Colonização e Reforma Agraria (INCRA/SP), whose activities were carried out throughout 2011. In methodological terms, the research was divided into two stages. In the first stage, it sought to identify the main economic activities, vocations and potential of the influencing areas of the Quilombola communities and settlements in their respective regions and micro-regions. Therefore, a survey was conducted based on secondary data. In the second stage, a qualitative, exploratory, empirical, and multiple case study research was conducted. Local public officials, in charge of the institutional relations with the agrarian reform settlements (and quilombolas communities, in this case, one of the municipalities investigated) were the primary source of data for this analysis that sought to evaluate the strength, types and quality of support (plausible or effective) provided by the municipalities to the economic activities of settlements. The results indicated a set of reasonably heterogeneous components, and frequently, distinct, of particular circumstances. Based on the results some proposals for action plans were indicated, which probably would constitute a standard reference for the formulation and implementation of public policies and actions to improve the economic activities of the settlements.

Políticas públicas municipais de apoio a atividades econômicas em assentamentos rurais: uma análise em quatro municípios paulistas

This paper reports a master research that aimed to analyze the patterns of institutional relationships between local officials and communities of agrarian reform settlements in four counties of the State of São Paulo – Apiaí, Iaras, Promissão and Mirante do Paranapanema – particularly with regard to the types of support offered by the first to the economic activities in the settlements. In terms of methodology, we conducted a qualitative, exploratory and descriptive research, outlined in the format of multiple case study. Having like data sources the local officials responsible for institutional relations with the agrarian reform settlements, technicians agents of agencys linkeds to the land question, as INCRA and ITESP, and settled in leadership positions in rural settlements, we sought to evaluate the intensity, the types and quality of the (possible or actual) support offered by municipalities to economic activities inside the settlements. We sought to evaluate the results from theoretical lens formed around the notions of local development and the significance assumed by settlements in different locations. The results showed a fairly heterogeneous and, often, disparate in particular circumstances. It was evident, from the information collected, that a positive action of the municipal government in supporting the economic activities of the settlements is essential for the release of social energy based in settlements, enabling the realization of the "amalgam of possibilities" constructed from the implementation of rural settlements.
