Arsenic speciation in the freshwater crayfish, Cherax destructor Clark

Arsenic is a proven carcinogen that is found in the soil in gold mining regions at concentrations that can be thousands of times greater than gold. During mining arsenic is released into the environment, easily entering surrounding water bodies.
The yabby (Cherax destructor) is a common freshwater crustacean native to Australia's central and eastern regions. Increasing aquaculture and export of these animals has led us to question the effects of mine contamination on the yabbies themselves and to assess any potential risks to consumers. This study determined the species of arsenic present in a number of organs from the yabby. Several arsenic contaminated dam sites in the goldfields of western Victoria were sampled for yabby populations. Yabbies from these sites were collected and analysed for arsenic speciation using high performance liquid chromatography–inductively coupled plasma-mass spectrometry (HPLC–ICP-MS). Results showed that type of exposure influenced which arsenic species was present in each organ, and that as arsenic exposure increased the prevalence of inorganic arsenic species, mostly As(V), within the tissues increased. The bioaccessibility of the arsenic present in the abdominal muscle (the edible portion for humans) of the yabbies was assessed. It was found that the majority of the bioaccessible arsenic was present as inorganic As (III) and As(V).

Poor governance sickens the Arts : we have the cure, Kenneth Myer Lecture for the George Fairfax Fellowship

We need to know more about governance in cultural nonprofit organisations (NPOs). Can good governance prevent financial crises in arts organisations? A vast research project has helped find the answers. Lack of artistic success is not the main cause of financial distress. NPOs in financial distress often have weak governing processes. Their board members need to know more about the problems leading to the crisis. We propose a governance framework to better monitor NPOs’ external and internal environments. Then we present the reactions to this governance framework from interviews with NPO managers. Finally, we report results from arts organisation consultancy and reconcile these findings with the ones collected through interviews.

Defending friends : Robert Codrington, George Sarawia and Edward Wogale

Friendship between nineteenth century missionary anthropologists and their converted cultural mentors was central to the gathering of cultural and linguistic information. This chapter traces the friendship between Anglican missionary/anthropologist, Robert Codrington, and brothers George Sarawia - first Melanesian priest - and Edward Wogale - deacon. Codrington's theological perspective on Melanesians and his close friendships with the pupils of the Melanesian Mission School at Norfolk Island allowed him to resist the increasing racialism of Atlantic science in the late nineteenth century and to challenge the evolutionist anthropology of the 1870s and 1880s. The chapter is based, in part, on a cache of letters from Wogale and Sarawia to Codrington written in Mota, the lingua franca of the Anglican Mission.

The demise of Bicycle George : a life of crime

This short piece looks at the life of a murderer, George Blunderfield (alias Arthur Oldring), who was hanged in Melbourne in 1918. Melburnians, or visitors to the city, may have seen his image on the wall at the Old Melbourne Gaol. Blunderfield's life started out normally
enough, and then descended into horrific crime. His story includes bicycle racing, escape from an island prison, and then recruitment for service with the Australian Imperial Forces in wartime Victoria. In the last years of his life, Blunderfield wreaked havoc from the western to the eastern coasts of Australia. This in turn had a dramatic effect on his immediate family, which is also detailed here. This story draws on the archives at PROV as well as on State Records Office of Western Australia material, with help from Ms Jean
Bellamy, a distant relative of George Blunderfield.
