Spinor condensates and light scattering from Bose-Einstein condensates

These notes discuss two aspects of the physics of atomic Bose-Einstein condensates: optical properties and spinor condensates. The first topic includes light scattering experiments which probe the excitations of a condensate in both the free-particle and phonon regime. At higher light intensity, a new form of superradiance and phase-coherent matter wave amplification were observed. We also discuss properties of spinor condensates and describe studies of ground--state spin domain structures and dynamical studies which revealed metastable excited states and quantum tunneling.Comment: 58 pages, 33 figures, to appear in Proceedings of Les Houches 1999 Summer School, Session LXXI

Chirality of reduced haloperidol in humans

In vitro, cytosolic human ketone reductases catalyse the stereospecific (i.e. >99%) formation of S(-) reduced haloperidol (RHP) from haloperidol (HP). Whether this situation is reflected in patients taking the drug is unknown. In this study in nine patients taking HP, only 73.2+/-18.2% of the RHP excreted in urine was the S(-) enantiomer. Thus, enzymes other than cytosolic ketone reductases must be responsible for the formation of the minor enantiomer. (C) 1998 Elsevier Science B.V./ECNP

Imagining Personhood Differently: Person Value and Autonomist Working-Class Value Practices

Theories of the good and proper self (the governmental normative subject, be it a reflexive, enterprising, individualising, rational, prosthetic, possessed self) or even the self produced in conditions not of its own making, such as Bourdieu’s habitus, all rely on ideas about self-interest, investment and/or ‘playing the game’. As people are increasingly expected to publicly legitimate themselves as good and worthy subjects and as capital increasingly enters the spaces of intimacy and bio-politics, we need to consider the limits of our theoretical imaginaries for understanding the value production necessary to the performance of personhood. Specifically, most of the theories we have for understanding the connections between personhood and value reproduce and legitimate the normative, hinging our theoretical imaginary to the dominant symbolic, making proper personhood an exclusive resource predicated on constitution by exclusion; where limits define the norm, the margins the centre and the improper the proper. How then can we understand how people who are excluded from the possibilities of accruing and attaching value to themselves, who are positioned outside of the dominant symbolic as the constitutional limit for the proper self or as the zero limit to culture, develop value/s? Drawing upon three different empirical research projects the paper builds on my previous critique of the self as a classed concept to develop a different perspective on value. It argues that an analysis of autonomist working class sociality offers us ways to imagine personhood and person value that are often imperceptible to the bourgeois gaze
