Far infrared filters for the GALILEO-Jupiter and other missions

Extrapolation of PbTe/II-VI multilayer interference-filter technique from 20 to beyond 40µm is described and PbTe transparency reviewed; improvements below 20µm are reported. A composite filter cutting on steeply at 40µm is described that uses absorptive films of ZnS and As2S3, thin Quartz, and supplementary multilayer interference. Absorptive filters are described containing the II-VI compounds since these are found transparent at wavelengths shorter and longer than their reststrahl.

The Life of Galileo and Brechtian television drama

Bertolt Brecht's dramaturgy was as influential upon the development of British drama on television between the 1950s and the 1970s as it was in the theatre. His influence was made manifest through the work of writers, directors and producers such as Tony Garnett, Ken Loach, John McGrath and Dennis Potter, whose attempts to create original Brechtian forms of television drama were reflected in the frequent reference to Brecht in contemporary debate concerning the political and aesthetic direction and value of television drama. While this discussion has been framed thus far around how Brechtian techniques and theory were applied to the newer media of television, this article examines these arguments from another perspective. Through detailed analysis of a 1964 BBC production of The Life of Galileo, I assess how the primary, canonical sources of Brecht's stage plays were realised on television during this period, locating Brecht's drama in the wider context of British television drama in general during the 1960s and 1970s. I pay particular attention to the use of the television studio as a site that could replicate or reinvent the theatrical space of the stage, and the responsiveness of the television audience towards Brechtian dramaturgy.

Flexionar ou não flexionar, eis a questão: infinitivos no Português como segunda língua

À luz de previsões feitas por duas abordagens concorrentes na aquisição de L2 por adultos – Acesso Total (FA, Full Access) (e.g., White 1989, 2003; Schwartz & Sprouse 1996) e Traços Malsucedidos (FF, Failed Features) (e.g., Hawkins & Chan 1997; Liceras & Díaz, 1999) – o presente estudo examina a aquisição de infinitivos flexionados por adultos aprendizes de português como L2, falantes nativos de inglês e bilíngues de espanhol/inglês. A aquisição total semelhante ao nativo de infinitivos flexionados requer a reconfiguração de um parâmetro sintático (o Parâmetro do Sujeito Nulo) e um parâmetro morfológico (o Parâmetro-Infl) para esses aprendizes. Como as abordagens FF sustentam um período pós-crítico de insucesso na aquisição de novos traços na L2, ausentes na L1, prevê-se que a aquisição típica da língua alvo não seja possível. Por outro lado, as abordagens FA, que sustentam a possibilidade da reconfiguração dos parâmetros nos adultos, preveem que a competência nativa de infinitivos flexionados seja alcançável, mas não inevitável. Os dados que apresentamos apoiam as abordagens FA, e demonstram que os adultos aprendizes avançados alcançam um conhecimento interpretativo dos infinitivos flexionados do português semelhante ao de nativos. Também consideramos o papel da transferência da L1 e as implicações possíveis, já que diferem para ambos os grupos.
