On the significance of the basic structure: a priori baseline views and luck egalitarianism

This paper uses the exploration of the grounds of a common criticism of luck egalitarianism to try to make an argument about both the proper subject of theorising about justice and how to approach that subject. It draws a distinction between what it calls basic structure views and a priori baseline views, where the former take the institutional aspects of political prescriptions seriously and the latter do not. It argues that objections to luck egalitarianism on the grounds of its harshness can in part be explained by this blindness to relevant features of institutions. Further, it may be that luck egalitarianism cannot regard its own enactment as just. A related objection to Dworkin’s equality of resources, which claims that it cannot pick a particular institutional background to set the costs of resources and so is radically indeterminate, is also presented. These results, I argue, give us good reason to reject all a priori baseline views.

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.

GNSS occultation sounding for climate monitoring

Considerable efforts are currently invested into the setup of a Global Climate Observing System (GCOS) for monitoring climate change over the coming decades, which is of high relevance given concerns on increasing human influences. A promising potential contribution to the GCOS is a suite of spaceborne Global Navigation Satellite System (GNSS) occultation sensors for global long-term monitoring of atmospheric change in temperature and other variables with high vertical resolution and accuracy. Besides the great importance with respect to climate change, the provision of high quality data is essential for the improvement of numerical weather prediction and for reanalysis efforts. We review the significance of GNSS radio occultation sounding in the climate observations context. In order to investigate the climate change detection capability of GNSS occultation sensors, we are currently performing an end-to-end GNSS occultation observing system simulation experiment over the 25-year period 2001 to 2025. We report on this integrated analysis, which involves in a realistic manner all aspects from modeling the atmosphere via generating a significant set of stimulated measurements to an objective statistical analysis and assessment of 2001–2025 temporal trends.
