O objetivo central deste trabalho é verificar a influência das teorias econômicas na decisão das empresas de comércio atacadista em terceirizar o despacho aduaneiro na cidade de São Paulo. Para isso, a história da terceirização é apresentada brevemente, seguida do levantamento e estudos sobre terceirização e fundamentação das teorias econômicas que mostram possíveis influências na decisão das empresas em terceirizar o despacho aduaneiro: a Teoria do Custo das Transações, a Teoria da Agência, a Teoria do Resource-Based View (RBV) e a Teoria das Competências Essenciais. Além de contextualizar o comércio exterior brasileiro, levando em conta sua história e representatividade econômica, foram apresentadas as atividades ligadas ao despacho aduaneiro, que podem levar as empresas a terceirizar este serviço na cidade de São Paulo. Após a explanação sobre o tema, por meio de pesquisa empírica valendo-se de questionário de perguntas fechadas, aplicado a uma amostra não probabilística por conveniência, verificou-se a relação existente entre as teorias mencionadas acima e o quanto elas influenciam o processo das empresas importadoras e exportadoras do comércio atacadista para terceirizarem o despacho aduaneiro, foi usado o teste ANOVA e possíveis complementações como o do Teste de Dunnett T3 e do Teste de Tukey que constataram a diferença de respostas entre os respondentes que terceirizam totalmente, parcialmente ou não terceirizam esta atividade, além da diferença entre estes níveis de terceirização verificou-se que todas as teorias econômicas apresentadas neste trabalho possuem alguma influência sobre a terceirização do despacho aduaneiro.

This work aims to demonstrate the feasibility of a ceramic composite containing fiber in the rubber manufacturing interlocking blocks. Gravel, sand, cement, rubber and fiber: the processes of manufacture and assembly of blocks produced and the various formulations studied with different proportions between the constituent elements were addressed. Mechanical properties were determined for the different formulations, compressive strength, diametral compressive strength, water absorption and apparent density, obeying the rules related to each property. It was concluded that the addition of rubber fiber gave the concrete studied resistance lower than conventional concrete which can be verified on the microstructural analysis obtained by SEM, which revealed the presence of pores and the low adhesion between the fiber and the matrix compression (tire fiber / cement paste). The composite of more viable tire BCPB1 (1/2) fiber can be used in places requests as light squares, pavements, roads and other cycle as well as in the manufacture of the curb and gutter, by having compressive strength in about 20 MPa

The use of composite materials for the construction industry has been the subject of numerous scientific papers in Brazil and in the world. One of the factors that motivate this quest is the housing deficit that countries especially the third world face. In Brazil this deficit reaches more than 6.5 million homes, around 12% of all US households . This paper presents a composite that was obtained from waste generated in processes for the production of granite and marble slabs, cement, gypsum, sand, crushed EPS and water. These wastes cause great damage to the environment and are thrown into landfi lls in bulk. The novelty of the work is in the combined study thermal, mechanical and acoustic composite obtained in real situation of rooms that are part of an experimental housing. Many blocks were made from cement compositions, plaster, foam, sand, marb le and / or granite, preliminary tests of mechanical and thermal resistance were made by choosing the most appropriate proportion. Will be given the manufacturing processes and assembly units 500 units 10 x 80 x 28 cm produced for the construction of an ex perimental home. We studied what kind of block and residue, marble or granite, made it more feasible for the intended purpose. The mechanical strength of the produced blocks were above 3.0 MPa. The thermal resistance of the blocks was confirmed by the maxi mum temperature difference between the inner and outer walls of rooms built around 8.0 ° C. The sound absorption for optimal room was around 31%. Demonstrated the feasibility of using the blocks manufactured with composite material proposed for construction.
