Technological And Productive Density In Sectoral Innovation Systems: The Case Of The Brazilian Aeronautics Industry
This article discusses whether a globally competitive high-tech firm is sustainable without being associated with a sufficiently dense sectoral innovation system. It focuses on Embraer and hence on the Brazilian aeronautics industry. Despite not benefiting from a highly subsidized process for technological and financial modernization, Embraer has become the world's third-ranking producer of commercial jets thanks to institutional innovations, especially in producing and managing contracts with suppliers and risk-sharing partners. The conclusion drawn is that the competitiveness of the Brazilian aircraft industry depends on the continuing supply of technology in international markets. Technological restrictions imposed for geopolitical reasons, or even for market constraints, could fatally undermine the strategy adopted by the company. © Universidad Alberto Hurtado, Facultad de Economía y Negocios.646072(2010), http://www.anac.gov.br, AGÊNCIA NACIONAL DE AVIAÇÃO CIVIL, ANAC, Home page, accessed Aug. 27, 2010Bernardes, R., O Caso Embraer - Privatização e Transformação da Gestão Empresarial: Dos Imperativos Tecnológicos à Focalização no Mercado (2000) Cadernos De Gestão Tecnológica, p. 46. , CYTED: PGT/USP, São PauloBertazzo, R.P., (2003) A Crise Da Indústria Aeronáutica Brasileira, pp. 1945-1968. , BA Dissertation, Universidade Federal de Juiz de Fora, Instituto de Ciências Humanas e de Letras, Curso de HistóriaCassiolato, J.E., Lastres, H.M.M., (2005) Sistemas De Inovação E Desenvolvimento: As Implicações De Política, 19. , São Paulo em Perspectiva, n. 1, p. 34-45, jan./mar. 2005http://www.bcb.gov.br, CENTRAL BANK OF BRAZIL (Banco Central do Brasil - BC), accessed Dec. 22, 2010Dagnino, R., (1993) The Aeronautics Industry.

Transverse Ising Model: Markovian evolution of classical and quantum correlations under decoherence
The transverse Ising Model (TIM) in one dimension is the simplest model which
exhibits a quantum phase transition (QPT). Quantities related to quantum
information theoretic measures like entanglement, quantum discord (QD) and
fidelity are known to provide signatures of QPTs. The issue is less well
explored when the quantum system is subjected to decoherence due to its
interaction, represented by a quantum channel, with an environment. In this
paper we study the dynamics of the mutual information , the
classical correlations and the quantum correlations
, as measured by the QD, in a two-qubit state the density matrix
of which is the reduced density matrix obtained from the ground state of the
TIM in 1d. The time evolution brought about by system-environment interactions
is assumed to be Markovian in nature and the quantum channels considered are
amplitude damping, bit-flip, phase-flip and bit-phase-flip. Each quantum
channel is shown to be distinguished by a specific type of dynamics. In the
case of the phase-flip channel, there is a finite time interval in which the
quantum correlations are larger in magnitude than the classical correlations.
For this channel as well as the bit-phase-flip channel, appropriate quantities
associated with the dynamics of the correlations can be derived which signal
the occurrence of a QPT.Comment: 8 pages, 7 figures, revtex4-1, version accepted for publication in
