Responding to cyberbullying: the case for family conferencing
Cyberbullying is a form of anti-social conduct which is best understood as an online social relationship problem. Because of our growing understanding of the phenomenon, we can now see that any socio-legal response should envisage, therefore, a relationship solution. This article considers how one diversionary criminal justice process is particularly well suited to responding to incidents of cyberbullying where juveniles are involved yet which are deemed to be sufficiently serious to attract a potential criminal penalty. It explores, specifically, the option of family conferences (facilitated by youth justice co-ordinators) within the South Australian youth court framework. It concludes that both young cyberbullies and young victims of cyberbullying may benefit from alternatives to a retributive justice process, given that the primary focus of family conferencing is the repair of harm and the restoration of relationships.Colette Langos, Rick Sarr
The ERE of the "Red Rectangle" revisited
We present in this paper high signal-to-noise long-slit optical spectra of
the Extended Red Emission (ERE) in the "Red Rectangle" (RR) nebula. These
spectra, obtained at different positions in the nebula, reveal an extremely
complex emission pattern on top of the broad ERE continuum. It is well known
that three features converge at large distance from the central object, in
wavelength and profile to the diffuse interstellar bands (DIBs) at 5797, 5849.8
and 6614 ang., (e.g. Sarre et al., 1995). In this paper we give a detailed
inventory of all spectral subfeatures observed in the 5550--6850 ang. spectral
range. Thanks to our high S/N spectra, we propose 5 new features in the RR that
can be associated with DIBs. For the 5550--6200 ang. spectral range our slit
position was on top of the NE spike of the X shaped nebula. A detailed
description of the spatial profile-changes is given of the strongest features
revealing that even far out in the nebula at 24 arcsec from the central star,
there remains a small shift in wavelength of 1 respectively 2 ang between the
ERE subfeatures and the DIB wavelengths of 5797.11 and 5849.78 ang.Comment: 8 pages, 9 figures accepted by Astronomy and Astrophysic
Sequence structure emission in The Red Rectangle Bands
We report high resolution (R~37,000) integral field spectroscopy of the
central region (r<14arcsec) of the Red Rectangle nebula surrounding HD44179.
The observations focus on the 5800A emission feature, the bluest of the
yellow/red emission bands in the Red Rectangle. We propose that the emission
feature, widely believed to be a molecular emission band, is not a molecular
rotation contour, but a vibrational contour caused by overlapping sequence
bands from a molecule with an extended chromophore. We model the feature as
arising in a Polycyclic Aromatic Hydrocarbon (PAH) with 45-100 carbon atoms.Comment: 13 pages, 9 figures, accepted for publication in ApJ. A version of

WIND-PVPA: Water/Ion NMR Detected PVPA to assess lipid barrier integrity in vitro through quantification of passive water- and ion transport
Water/Ion NMR Detected – Phospholipid Vesicle Permeability Assay (WIND-PVPA), is presented as a novel,
straightforward and automatable method to assess lipid barrier integrity in vitro. The apparent permeability
constants of water- and ions across the PVPA barriers are determined in a one-pot experiment under the influence
of membrane-active guest molecules. NMR spectroscopy is used to quantify the water directly (D2O) and the ions
indirectly (complexed with EDTA) as a function of time. WIND-PVPA is demonstrated using four anti-microbial
peptides, to show that membrane active molecules can be differentiated by their disruptive influence on the
PVPA system. The results obtained are compared with explicit molecular dynamics simulations of lipid bilayers,
AMPs, water and salt, where the motions of all individual water molecules relative to the lipid bilayer are
monitored over the course of the simulations, allowing the calculation of theoretical apparent permeability
constants of the corresponding single bilayer systems.
Proof-of-principle is presented that WIND-PVPA can be used to evaluate the lipid barrier destabilizing effect of
active guest molecules by measuring changes in passive water- and ion permeabilities upon exposure. The
method is highly flexible in terms of barrier composition, choice of probes and membrane active compounds

Mediating punitiveness: understanding public attitudes towards work-related fatality cases
This paper concerns an empirical investigation into public attitudes towards work-related fatality cases, where organizational offenders cause the death of workers or members of the public. This issue is particularly relevant following the introduction of the Corporate Manslaughter and Corporate Homicide Act 2007 into UK law. Here, as elsewhere, the use of criminal law against companies reflects governmental concerns over public confidence in the law’s ability to regulate risk. The empirical findings demonstrate that high levels of public concern over these cases do not translate into punitive attitudes. Such cases are viewed rationally and constructively, and lead to instrumental rather than purely expressive enforcement preferences
