A Reforma do Estado: Qual a Natureza da Política Educacional nos Anos 1990?
Over the last years, educational policies have been modified with regard to discussed items, and certain issues agreed upon by educators during the 1980s have been redefined. Current research analyzes the reforms brought about by the State that affected the educational politics in the 1990s, and which contributed towards forms of funding and administering the educational system. The neo-liberal reforms adopted justified the responsibility of the State for the established crisis and demanded reforms in the State and in its institutions. It was thus expected that distortions would be corrected and efficiency generated so that Brazil would be inserted within capitalist production. Current research highlights issues attributed to decentralization which foregrounded government policies that deprived people of their rights and somewhat constructed the consistencies of the movement. In fact, its central bases include the rationing of the federal government’s resources to adopt a decentralization strategy with the ensuing outsourcing, thereby shunning autonomy and democratic participation.
Federalismo, Governabilidade e Gestão Orçamentária
O problema central do estudo foi identificar como se processam as decisoes federativas no Brasil em relacao a intervencao legislativa no trato da questao orcamentaria. O artigo traz um recorte teorico embasado nos principios do federalismo brasileiro instituido apos a Constituicao de 1988 e uma analise comparativa dos arranjos institucionais (partidos e comissoes) que foram construidos para a manutencao da governabilidade do Executivo nacional e assim amortecer o conflito das questoes regionais interpostas pelo Legislativo.
Slotted Waveguide Antenna With Two Radiation Nulls
A design of a linear array antenna having two radiation nulls and otherwise omnidirectional radiation pattern is reported. A new configuration of a waveguide broad wall longitudinal slot doublet with positive and negative offsets with respect to the waveguide center line is used to design the array. This type of doublet produces two radiation nulls. Each of the null directions can be shifted at least up to plusmn25deg by proper choice of slot offset. Resonance and radiation characteristics of the proposed doublet are also presented. Finally, one linear array antenna consisting of seven doublets has been fabricated. Measurements show that the 15 dB null widths are 14.2deg and the null depths are at least 24.8 dB. Maximum gain ripple in the omnidirectional region is 1.75 dB.
