Do pride and prejudice stand in the way of persuasion? Embracing other disciplines for the advancement of advocacy teaching
This paper considers the importance of advocacy teachers adopting a multi-disciplinary approach to the teaching of advocacy and suggests how this can be acieved
SYMPOSIUM on forecasting the state of the public finances
The level of public borrowing plays a central role in UK government policymaking, especially in the run-up to each Budget. Accurate forecasts of the overall fiscal stance are crucial in assessing the general health of the economy, the direction of tax policy and the volume of public services that can be supplied. But these forecasts have a relatively poor record in the UK in recent years. The government’s last Financial Statement and Budget Report noted that ‘The budget deficit is the difference between two large aggregates of spending and receipts and forecasts of it are inevitably subject to a wide margin of error. Over the past five years the average absolute errors have been around 1 per cent of GDP, or plus or minus £8 billion in today’s prices’.
Last scattering, relic gravitons and the circular polarization of the CMB
The tensor contribution to the -mode polarization induced by a magnetized
plasma at last scattering vanishes exactly. Conversely a polarized background
of relic gravitons cannot generate a -mode polarization. The reported
results suggest that, in the magnetized CDM paradigm, the dominant
source of circular dichroism stems from the large-scale fluctuations of the
spatial curvature.Comment: 8 pages, no figure
Heroin addiction: the past and future
Substance misuse, in particular heroin addiction contributes to health and social problems. Although effective medical treatment was available, earlier efforts confined the treatment of heroin addicts to in-house rehabilitation which required them to be estranged from the community and their families for 2 years. The in-house rehabilitative programme, implemented for at least three decades has produced low abstinence rates. On the other hand, being ‘away’ meant that many heroin addicts faced employment problems and family relationship difficulties upon completing the in-house rehabilitation. However, recently, the concerted efforts by various government and non-government organisations, and the acknowledgement that heroin addiction is a medical illness has resulted in a revamp to approaching treatment of heroin addiction. At present, methadone substitution programmes have been offered as part of treatment programme for heroin addicts in Malaysia. This new programme has been shown to be effective in treating heroin addiction and would need support and cooperation from all groups involved
Incoherent single pion electroproduction on the deuteron with polarization effects
Incoherent pion electroproduction on the deuteron is studied from threshold
up to the second resonance region with special emphasis on the influence of
final state interaction, in particular on polarization observables. The
elementary amplitude is taken from the MAID-2003 model.
Final state interaction is included by considering complete rescattering in the
final and subsystems. Their influence on the structure functions
governing the semi-exclusive differential cross section, where besides the
scattered electron only the produced pion is detected, is investigated in
detail. For charged pion-production the effect of -rescattering is moderate
whereas -rescattering is almost negligible, except very close to
threshold. -rescattering appears much stronger in neutral pion production
for which the primary mechanism is the elimination of a significant spurious
coherent contribution in the impulse approximation. Sizeable effects are also
found in some of the polarization structure functions for beam and/or target
polarizations.Comment: 20 pages including 14 figure
Composition dependence of ion transport coefficients in gas mixtures
A simple momentum-transfer theory for the composition dependence of ion mobilities and diffusion coefficients in gas mixtures at arbitrary field strengths is corrected, extended, and compared with a similar theory based on momentum and energy transfer, and with results based on direct solution of the Boltzmann equation by Kihara's method. Final equations are recommended for predicting composition dependences, given only results on ion mobilities and diffusion coefficients in the pure component gases
Incoherent pion photoproduction on the deuteron with polarization observables I: Formal expressions
Formal expressions are developed for the general five-fold differential cross
section of incoherent -photoproduction on the deuteron including beam and
target polarization. The polarization observables of the cross section are
described by various beam, target and beam-target asymmetries for polarized
photons and/or polarized deuterons. They are given as bilinear hermitean forms
in the reaction matrix elements divided by the unpolarized cross section. In
addition, the corresponding observables for the semi-exclusive reaction are also given.Comment: 11 pages, 1 figur
