Hearing Voices

A BBC Radio 4 Afternoon Play. A police detective starts having auditory halluincations but the case he is working on provides the clue to his deep-seated psychological conflict.

Moonmen

An hour-long radio play on BBC Radio 3. A space odyssey with a difference, Moonmen centres on a philosophical encounter between two isolated men - an astronaut and a CB radio enthusiast in rural Ireland. Are they polar opposites or kindred spirits locked in a mutual orbit?

Wigs on the Green

A six-part radio comedy series, co-writeen with John Murphy, set in the insane world of the Circuit Court in the Republic of Ireland. The series was broadcast by RTE Lyric FM.

Food of the Blue

An episode of BBC Radio 4's detective series 'Baldi'. Paolo Baldi finds himself in a world of superstar academics, but why are their bloodless corpses littering the college? And what is that thing they drink to rejuvenate the venerable institution?

Atomic oxygen surface loss coefficient measurements in a capacitive/inductive radio-frequency plasma

Spatially resolved measurements of the atomic oxygen densities close to a sample surface in a dual mode (capacitive/inductive) rf plasma are used to measure the atomic oxygen surface loss coefficient beta on stainless steel and aluminum substrates, silicon and silicon dioxide wafers, and on polypropylene samples. beta is found to be particularly sensitive to the gas pressure for both operating modes. It is concluded that this is due to the effect of changing atom and ion flux to the surface. (C) 2002 American Institute of Physics.

Plasma ionization through wave-particle interaction in a capacitively coupled radio-frequency discharge

Phase resolved optical emission spectroscopy, with high temporal resolution, shows that wave-particle interactions play a fundamental role in sustaining capacitively coupled rf plasmas. The measurements are in excellent agreement with a simple particle-in-cell simulation. Excitation and ionization mechanisms are dominated by beam-like electrons, energized through the advancing and retreating electric fields of the rf sheath. The associated large-amplitude electron waves, driven by a form of two-stream instability, result in power dissipation through electron trapping and phase mixing.

Role of low-energy electrons in Ar emission from low-pressure radio frequency discharge plasma

Optical emission spectra from a low-pressure Ar plasma were studied with high spatial resolution. It has been shown that the intensity ratios of Ar lines excited through metastable levels to those excited directly from the ground state are sensitive to the shape of electron energy distribution function. From these measurements, important information on the spatial variation of plasma parameters can be obtained. (C) 1999 American Institute of Physics. [S0003-6951(99)01629-0].

Structure observed in measured electron energy distribution functions in capacitively coupled radio frequency hydrogen plasmas

Electron energy probability functions measured with a passively compensated Langmuir probe in asymmetric capacitively coupled hydrogen and deuterium plasmas exhibit structure. The otherwise relatively continuous distribution appears to have an abrupt peak in electron density near 5 eV. This structure occurs at a higher energy in deuterium than hydrogen and there is a correlation between floating potential and the voltage at which the structure is observed in the second derivative of the I(V) characteristic. While the cause of the structure has yet to be clarified, spectroscopic observations and computer-based hydrogen models indicate that the high energy tail of the distribution is strongly modulated during the radio frequency cycle. The effect of this modulation on plasma properties and probe measurements has yet to be explored. (C) 1999 American Institute of Physics. [S0003-6951(99)00819-0].

State power matters: power, the state and political struggle in the post-war American novel

This article is concerned with resituating the state at the centre of the analytical stage and, concomitantly, with drawing attention to the dangers of losing sight of the state as a locus of power. It seeks to uncover the relationship between two related lines of critical inquiry: Marxist and Foucauldian theories of the state; and the attempts by three postwar American novelist (Ken Kesey, William Burroughs and E.L. Doctorow) to determine the nature and extent of this power and to consider under what conditions political struggle might be possible. It argues that such a move is needed because recent critical analysis has been too preoccupied by corporeal micropolitics and global macropolitics, and that the postwar American novel can help us in this move because it is centrally concerned with the repressive potentiality of the US state. It maintains that the resuscitation of Marxist state theories in early 1970s and a debate between Poulantzas and Foucault is intriguingly foreshadowed and even critiqued by these novels. Consequently, it concludes that these novels constitute an unrecognized pre-history of what would become one of the key intellectual debates of the late twentieth century: an engagement between Marxist and post-structuralist conceptions of the power and resistance.
