Estado, crédito e planejamento no desempenho da indústria da construção naval brasileira 1990-2010
The aim of this paper is discuss the recent economic history of the Brazilian shipbuilding industry from 1990 to 2010, highlighting the role of the state, through public policies for the domestic industry and credit linked to the Banco Nacional de Desenvolvimento Economico e Social (BNDES). During the period last 20 years, the Brazilian shipbuilding sector has undergone two distinct phases: partial dismantling and recovery activities. In addition to the introduction and final considerations, the article is divided into three topics. In the first, we will present a brief characterization of the shipbuilding industry highlighting its productive aspects, organizational and global participation. Will be detailed the process of dismantling part of the shipbuilding industry, focusing on the process of denationalization and in the absence of public policies more intensive. And, finally, will be feature the resumption of activities anchored in the naval orders from Petrobras and offshore vessels.
POLÍTICA DE EXPANSÃO DA INDÚSTRIA NAVAL E MERCADO DE TRABALHO: UMA ANÁLISE PARA OS POLOS NAVAIS REGIONAIS
Este trabalho tem por objetivo avaliar o impacto da expansão da indústria naval sobre o desempenho do mercado de trabalho dos municípios diretamente impactados pela política de expansão da indústria naval pertencentes aos estados do Rio Grande do Sul, Santa Catarina, Rio de Janeiro, Bahia e Pernambuco. Para tanto, foi construído um painel de informações sobre o mercado de trabalho em nível municipal no período 1999 a 2014, com base nas informações da RAIS e do CAGED. O método econométrico utilizado foi o método de diferenças em diferenças com efeito fixo de municípios. Os resultados encontrados demonstraram que a política de mobilização da indústria naval promoveu alterações no mercado de trabalho, ampliando o número de vagas sobretudo no segmento da indústria da transformação, da construção civil e do comércio.
Refinement of crystal structure parameters using convergent‐beam electron diffraction: the low‐temperature phase of SrTiO3
The method to refine crystal structure parameters (atom positions and Debye–Waller factors) using convergent-beam electron diffraction (CBED), which is applicable to crystal structure analysis of a small specimen area down to a few nm in diameter, is studied. The line profiles of higher-order Laue-zone reflections are recorded using imaging plates. Theoretical intensities are calculated based on the dynamical theory of electron diffraction with the aid of the generalized Bethe approximation to shorten calculation time. The structural parameters are determined by fitting the experimental profiles with the theoretical ones using a nonlinear least-squares method. The present method has been applied to the low-temperature phase of SrTiO3. The structural parameter or the rotation angle of the oxygen octahedron has been determined to be \varphi = 1.12 (4)°, which shows good agreement with that obtained from electron spin resonance experiments.
