Cadmium, copper, mercury, and zinc concentrations in tissues of the King Crab (Pseudocarcinus gigas) from southeast Australian waters

The concentrations of cadmium, copper, mercury, and zinc were determined in muscle (body, claw, and leg), hepatopancreas, and gill tissues of Pseudocarcinus gigas, an exceptionally large, long-lived, and deep-dwelling crab species. The accumulation patterns observed are discussed in terms of both intra- and interspecies variations, with particular attention to the possible consequences of the extreme size and depth range of P. gigas. Metal concentrations did not depend significantly on sex of the crab. Significant differences between tissues were detected for all metals, and the distribution of metal between the tissues was different for each metal. Significant correlations were found between metal concentrations in the various tissues and crab size, and these are discussed and rationalised. The concentrations of mercury and zinc in muscle tissue increased with crab size and were high compared to other crab species. The concentrations of cadmium and copper present in edible tissues were not especially high compared to other crab species, but the concentration of cadmium in the hepatopancreas is of dietary concern.

The influence of geometry and wall character of pores on the permeation of ions and water through desalination membranes

The transport of water and ions across mimicked nanotube membranes with pseudo atoms is studied using molecular dynamics simulations under equilibrium conditions and hydrostatic pressure. Different pore surface properties are constructed by assigning partial charges on the sites of specified atoms to explore the influence of charges and polarity. The energetics of water and ion transports through the nanopores was calculated to evaluate their filterability to water. The simulation results show that the free energy barriers to water and ion conductions much depend on the charges at the pore entrance and the dipole within the pore. The membranes with hydrophobic pores and negatively charged entrances would be very efficient in the water transport and ion rejection. The charges and dipoles of the pore wall and the aligned dipoles of water molecules in the pore can create a significant force on ions.

Shaking hands on the fringe : negotiating the Aboriginal world at King George's Sound

In 1826 the British set up a garrison on the edges of an Aboriginal world at King George’s Sound, the site of present day Albany, Western Australia, with the aim of deterring the French from occupying the area.

The British newcomers and the area’s Indigenous inhabitants, the King Ya-nup, came to share a small space, forcing both cultures to adapt in order to communicate and interact with one another. Within this sphere associations and friendships were formed that were as surprising as they were unique.

This ethnographic history narrates several intimate cross-cultural stories of the developing relationships between British and Aboriginal individuals at King George’s Sound. The episodes recounted go beyond the common ‘friendly’ or ‘violent’ encounters, unearthing instead how and why particular King Ya-nup engaged with the British world, utilising the new presence to seeming advantage.

Shaking Hands on the Fringe presents innovative history writing and beautifully crafted prose in the tradition of Greg Dening and other writers of ethnographic history.

Despite the limited scope of the subject, the first two points liberate this book into a national (and international) interest: it is not a local book.

The Carey 'king hit' : journalists and the coverage of domestic violence

In recent years Australia’s football codes have been rocked by allegations that star players, both past and present, have acted inappropriately off-field. In some instances these allegations have involved violence towards partners. This paper explores one such case, involving former AFL great Wayne Carey. In so doing, it explores the so-called ‘cult of celebrity’ and the impact this has both on the players and the media who cover such stories. People caught up in traumatic situations labelled as domestic violence have been vulnerable to media misunderstanding and misinterpretation. Coverage of these events and issues surrounding such violence has undergone change in line with social change. Work by community groups has produced calls for further shifts in thinking and suggestions for a name change to family violence. The so‑called ‘Wayne Carey Affair’ has demonstrated that journalists have their own vulnerabilities to the cult of celebrity, with extended interviews and coverage often centred on possible explanations/ “excuses” for the behaviour patterns of this one individual avoiding the wider social policy implications. By examining coverage surrounding Wayne Carey, this paper will explore the issues surrounding this major social problem and will question the role of journalists vis a vis the particularly vulnerable individuals caught up in family violence.
