Colonial sovereignty, forms of life and liminal beings in South Africa
No full textBook synopsis: Svirsky and Bignall assemble leading figures to explore the rich philosophical linkages and the political concerns shared by Agamben and postcolonial theory. Agamben's theories of the 'state of exception' and 'bare life' are situated in critical relation to the existence of these phenomena in the colonial/postcolonial world

Involutionary Architecture: Unyoking Coherence from Congruence
No full textBy focusing on the qualities of a posthumanist architectural practice inhis chapter 4, Andrej Radman continues the analysis of the genetic power ofaffective encounters begun by Iris van der Tuin in her opening chapter, and byJussi Parikka in his geophilosophical analysis of the emergent consequencesof constitutive relations for the operation of posthuman systems. Radmanargues that the recomposition of what Guattari refers to as ‘architecturalenunciation’ profoundly transforms the role of the architect, who becomes itsrelay by assuming the analytic and pragmatic responsibility for the productionnot merely of the environment, but of subjectivation itself. FollowingDeleuze’s Spinozism, and continuing the affective corporeal emphasis subsequently given to this in work by Brian Massumi, Radman suggests that if tothink differently one has to feel differently, and if the sole purpose of designis to change us, then architecture is effectively a ‘psychotropic practice’ thatmodulates and compels routines of experience.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.OLD Architectural Theor

The MASIV survey: Spectroscopic identifications of compact radio sources
No full textInterstellar scintillation (ISS) has been shown to be primarily responsible for the short term intraday variability (IDV) exhibited by extragalactic sources at centimeter wavelengths (e.g. Bignall et al. 2006 and references therein). For a source to scintillate its angular size must be comparable to that of the first Fresnel zone (Narayan 1992) which implies microarcsecond angular sizes for screen distances of tens to hundreds of parsecs. This has the potential to probe within a few light months of the central black hole (Bignall et al. 2006). The aim of the Microarcsecond Scintillation-Induced Variability (MASIV) survey was to provide a catalogue of at least a hundred AGNs that vary on timescales of hours to days to provide the basis of detailed studies of the IDV population drawn from a well-defined sample
Interstellar scintillation and annual cycles in the BL Lac source PKS 1519-273
No full textThe original publication can be found at www.springerlink.comWe have measured annual cycles in the time scales of the rapid, intra-day variability of the total and circularly polarized flux density, of the unusual BL Lac source PKS 1519–273 at 4.8 and 8.6 GHz. This data was collected at the ATCA over the last seven years, and establishes unequivocally interstellar scintillation as the principal mechanism responsible for this cm-wavelength intra-day variability.David L.

Supporting disabled children and their families in Scotland: A review of policy and research
No full textThe Joseph Rowntree Foundation has been supporting research about disabled children and their families for a number of years. An earlier Foundations covering the messages from these projects has already been published (1). This Foundations places the messages from that work into the Scottish context. It gives an overview of current policies affecting disabled children and their families in Scotland and draws on research carried out north of the border
