Financial control, blame avoidance and Radio Caroline: Talkin’ ‘bout my generation

This research examines the use of financial mechanisms that simultaneously impose controls and facilitate blame avoidance by public office-holders. A qualitative historical examination is used to examine legislation designed to prevent Radio Caroline, a pirate radio station, from broadcasting into Britain in the 1960s. Radio Caroline made a mockery of the British Government’s power to manage radio through a monopolist, the British Broadcasting Corporation. In addition, Radio Caroline played the type of rock music the British Government sought to suppress as representing the undesirable side of youth culture. This research examines the suppression of Radio Caroline through the Marine & Broadcasting (Offences) Act (UK) 1967 and the legislative scapegoating of Radio Caroline by targeting its revenue-earning potential. Inter-generational conflict underpinned the legislative scapegoating of Radio Caroline. This research demonstrates how financial controls can mask scapegoating and blame avoidance strategies by governments

Kinetic applications of electron paramagnetic resonance spectroscopy. II. Self-reactions of N-alkyl nitroxides and N-phenyl nitroxide

The self-reactions of methyl, isopropyl, tert-butyl, and phenyl nitroxides in solution have been examined by epr spectroscopy. The reaction is a disproportionation to yield a hydroxylamine and a nitroso compound: 2RNHO\ub7 \u2192 RNHOH + RNO. Rate constants for this reaction have been measured in several solvents. In benzene at 25\ub0 the rate constants are in the range 4 7 107 to 3 7 106 M-1 sec-1. For R = phenyl and R = tert-butyl the reaction was shown to be reversible and the equilibrium constants were measured over a range of temperature. The measured enthalpy change for the reaction with R = tert-butyl is in good agreement with that calculated (for R = CH3) from the heats of formation of the various species involved. Evidence is presented for hydrogen bonding of methyl nitroxide in methanol. The rate constant for the slow conversion of phenyl nitroxide to azoxybenzene has also been measured over a range of temperature in benzene.Peer reviewed: YesNRC publication: Ye

Cu2+, Fe2+ and Fe3+ analysis of bioleaching solutions using chronoamperometry and BDD electrode

In this work, a boron-doped diamond (BDD) electrode was evaluated for the electroanalytical determination of millimolar concentrations of Cu2+, Fe2+ and Fe3+ using chronoamperometry. The interfering role that each ion plays on the quantitative determination of other metal ion concentrations was also assessed. No interference from other metal ions was observed when Fe3+ and Fe2+ were analysed. By contrast, reduction of Fe3+ took place at the same potential where [Cu2+] was measured causing a minor interference to the Cu2+ signal. A multiple linear regression (MLR) calibration model was made for each analyte using real bioleaching samples, which demonstrated high coefficients of determination and adequate standard errors. The methods developed were used to monitor bioleaching of chalcopyrite for 4 months. The electroanalytical methods are particularly well-suited for analysing Cu2+, Fe3+ and Fe2+ concentration in acidic mine drainage (AMD) and bioleaching environments
