Toys for Boys? Women's Marginalization and Participation As Digital Gamers
This paper develops out of ongoing research into the location and use of digital gaming in practices of everyday life. Specifically this paper draws on a questionnaire based survey of just under four hundred undergraduate students and twenty-three follow up interviews. This paper suggests that the women in this research play digital games significantly less than their male counterparts, and suggests that this is largely due to digital games continuing to be viewed, both culturally and by the gaming industry, as belonging to men. However, this paper suggests that for some women video and computer gaming can be an important social activity, and for others mobile telephone based gaming can offer a less restricted and more accessible leisure activity.Gender, Digital Gaming

A Comment on "The Far Future of Exoplanet Direct Characterization" - the Case for Interstellar Space Probes
Following on from ideas presented in a recent paper by Schneider et al.
(2010) on "The Far Future of Exoplanet Direct Characterization", I argue that
they have exaggerated the technical obstacles to performing such 'direct
characterization' by means of fast (order 0.1c) interstellar space probes. A
brief summary of rapid interstellar spaceflight concepts that may be found in
the literature is presented. I argue that the presence of interstellar dust
grains, while certainly something which will need to be allowed for in
interstellar vehicle design, is unlikely to be the kind of 'show stopper'
suggested by Schneider et al. Astrobiology as a discipline would be a major
beneficiary of developing an interstellar spaceflight capability, albeit in the
longer term, and I argue that astrobiologists should keep an open mind to the
possibilities.Comment: Accepted for publication in Astrobiolog

Multifrequency Observations of One of the Largest Supernova Remnants in the Local Group of Galaxies, LMC - SNR J0450-709
We present the results of new Australia Telescope Compact Array (ATCA)
observations of one of the largest supernova remnants, SNR J0450-709, in the
Local Group of galaxies. We found that this Large Magellanic Cloud (LMC) ob
ject exhibits a typical morphology of an old supernova remnant (SNR) with
diameter D=102x75+-1 pc and radio spectral index alpha=-0.43+-0.06. Regions of
high polarisation were detected with peak value of ~40%.Comment: 7 pages, 4 figures, accepted for publication in Serbian Astronomical

Variational calculations for resonance oscillations of inhomogeneous plasmas
The electrostatic resonance properties of an inhomogeneous plasma column are reported by application of the Rayleigh-Ritz method. A description of the rf equation of motion and pressure term that expresses the system of equations in Euler-Lagrange form is presented. The Rayleigh-Ritz procedure is applied to the corresponding Lagrangian to obtain approximate resonance frequencies and eigenfunctions. An appropriate set of trial coordinate functions is defined, which leads to frequency and eigenfunction estimates
