Body dissatisfaction, appearance investment and wellbeing: how older obese men orient to 'aesthetic health' [forthcoming]
Most research on male body image to date has focused on young men using quantitative methods. The study reported here is based on qualitative interviews with a sample of older men (n = 30) on a weight management programme, and we asked them about body-related feelings. The interviews were all transcribed and analysed using thematic analysis. Our results indicate that although body weight was typically minimised, body image was a key concern, with many examples of body consciousness and body dissatisfaction evident. On the other hand, post-programme weight loss was associated with a transformative shift in body image, with the men emphasising enhanced body confidence, self-esteem and psychological wellbeing. We conclude by highlighting the need to recognise and address appearance issues and/as health concerns for middle-aged and older men
Experimental Study of Diamond Like Carbon (DLC) Coated Electrodes for Pulsed High Gradient Electron Gun
For the SwissFEL Free Electron Laser project at the Paul Scherrer Institute,
a pulsed High Gradient (HG) electron gun was used to study low emittance
electron sources. Different metals and surface treatments for the cathode and
anode were studied for their HG suitability. Diamond Like Carbon (DLC) coatings
are found to perform exceptionally well for vacuum gap insulation. A set of DLC
coated electrodes with different coating parameters were tested for both vacuum
breakdown and photo electron emission. Surface electric fields over 250MV/m
(350 - 400kV, pulsed) were achieved without breakdown. From the same surface,
it was possible to photo-emit an electron beam at gradients up to 150MV/m. The
test setup and the experimental results are presentedComment: 4 pages, 14 figures, IPMHVC 2010 : IEEE International Power Modulator

Asteroseismic study of solar-like stars: A method of estimating stellar age
Asteroseismology, as a tool to use the indirect information contained in
stellar oscillations to probe the stellar interiors, is an active field of
research presently. Stellar age, as a fundamental property of star apart from
its mass, is most difficult to estimate. In addition, the estimating of stellar
age can provide the chance to study the time evolution of astronomical
phenomena. In our poster, we summarize our previous work and further present a
method to determine age of low-mass main-sequence star.Comment: 2 pages, 1 figures, submitted to IAUS25
On the magnetic field required for driving the observed angular-velocity variations in the solar convection zone
A putative temporally varying circulation-free magnetic-field configuration
is inferred in an equatorial segment of the solar convection zone from the
helioseismologically inferred angular-velocity variation, assuming that the
predominant dynamics is angular acceleration produced by the azimuthal Maxwell
stress exerted by a field whose surface values are consistent with photospheric
line-of-sight measurements.Comment: to appear in MNRA
The impact of occupational pensions on retirement age
This article contributes to the debate about retirement age and the extent to which occupational pensions influence the decision to retire. It uses the waves of Labour Force Survey (1984-91) and Quarterly Labour Force Survey (1992-2003) to review the changes in the actual average retirement age in the UK during the period 1984-2003 by gender and ethnicity. The article investigates the link between occupational pension schemes and the actual retirement age of men and women. It explores the impact of pension type on employees' expected retirement age and the decision to take early retirement using the English Longitudinal Survey of Ageing (2002-03)

Modelling and forecasting international interest rate spreads: UK, Germany, Japan and the US
The interest rate spread is of importance to policy-makers and finance professionals in asset allocation and is a common measure of financial market stress. In this paper, we model and forecast the interest rate spreads for a number of countries using two well-known continuous time models and discrete time ARMA and ARFIMA models. We use monthly and weekly data which cover the recent global financial market crisis of 2007-2009 for Germany, Japan, UK and the USA. We find that the Merton's continuous-time model outperforms all other model specifications in terms of the mean of the forecast errors, MAPE and RMSE
An empirical analysis of the performance of pension funds: evidence from UK
Purpose - This paper examines the investment performance of pension funds in the UK using three standard performance measurement models, the CAPM, Fama-French model and the Carhart model.
Design/methodology/approach - We use the CAPS-Mellon survey data for the period 1990-2008 and employ the three standard performance measurement models, the CAPM, Fama-French model and the Carhart model in assessing the investment performance of the pension funds.
Findings - We show that the abnormal returns of pension funds cannot be fully explained by size, book-to-market values, market returns, momentum and the term spread. We find larger abnormal returns in bond than in equity portfolios and that smaller funds outperform larger funds. The paper also shows that the addition of the momentum factor does not improve on the three factor Fama-French model. We find that pension funds exhibit superior performance relative to the linear factor models.
Research limitations/implications - This study contributes to the extant literature on pension funds performance. Future research may also extend our work to incorporate economic, tax, political and legal differences across the countries on the performance of pension funds. Secondly, due to data constraints, this study excludes the default probability of corporate bonds as an additional variable in their tests on bond returns. Future work may add the default probability as an additional variable whilst examining bond returns
Practical implications - The authors believe that the findings will be considerable food for thought for fund managers who are continuously attempt to explore opportunities to provide a higher return to investors.
Originality/value - To our knowledge this is the first comprehensive study that investigates the performance of UK equity and bond pension funds relative to standard linear factor models such as the CAPM, Fama and French (1993), and Carhart (1997)
