The South Australian Museum boasts the largest and most comprehensive cetacean collection in Australia, including various large cetacean skeletons. The preparation of these skeletons was done at various locations throughout the history of the Museum until the state government funded a purpose-built preparation facility which opened in 1983. The well-equipped centre was fitted with a large (2800 L) custom-built liquid-vapour degreaser that used trichloroethylene (TCE) as solvent. Many beautifully degreased skeletons, including a 22 m pygmy blue whale, were prepared during its 15-year operation. An accidental spill of TCE in 1999 led to the decommissioning of the unit. The decision to abandon the use of the toxic and dangerous TCE has led to a series of experiments to find a benign replacement process that will work either with the existing degreaser or heated maceration vats. Numerous chemicals and treatment methods have been trialled with limited success. However, one particular group of chemicals, glycol ether surfactant compounds, has shown promise and has been the main focus for our ongoing studies. Glycol ethers are broad-spectrum active solvents characterised by high dilution ratios, low evaporation rates and wide solubility range. Their unique solubility characteristics also allow them to be used as a coupling solvent in more complex situations containing both hydrophilic and hydrophobic components, and because of their compatibility with non-ionic surfactants, blended formulations with glycol ether solvents may provide a new solution to an old problem.

AbstractAlthough visual culture of the 21th century increasingly focuses on representation of death and dying, contemporary discourses still lack a language of death adequate to the event shown by pictures and visual images from an outside point of view. Following this observation, this article suggests a re-reading of 20th century author Elias Canetti. His lifelong notes have been edited and published posthumously for the first time in 2014. Thanks to this edition Canetti's short texts and aphorisms can be focused as a textual laboratory in which he tries to model a language of death on experimental practices of natural sciences. The miniature series of experiments address the problem of death, not representable in discourses of cultural studies, system theory or history of knowledge, and in doing so, Canetti creates liminal texts at the margins of western concepts of (human) life, science and established textual form.

Colorado manages water using an administrative structure that is unique among the United States following the doctrine of prior appropriation: Water rights are adjudicated not by the State Engineer, but by Water Courts – separate from and operating in parallel to the criminal and civil courts – established specifically for this purpose. Fundamental to this system is the notion that water rights are property, with consequent protections under the US Constitution, but with the significant constraint that changes in water rights must not injure other water rights, either more senior or more junior. Population growth and climate change will certainly trigger changes in water administration, to be guided by the recent Colorado Water Plan. To provide the foundation necessary to appreciate these changes, this paper reviews the history of Colorado water administration and summarizes the complementary roles of the Water Courts and the State Engineer. Understanding water administration in Colorado depends on a firm grasp on how these two branches of state government formulate and implement water policy.

The research subject of this paper focuses on the Butonese, who are considered “outside” the local culture, despite having lived in the Moluccas islands of Indonesia for more than a hundred years. The Butonese compose the largest group of migrants to the Moluccas. This article research does not put ethnicity into a fixed, classified group of a population; rather, the research explores ethnicity as a living category in which individuals within ethnic groups also have opportunities for social mobility and who struggle for citizenship. The Butonese has a long history of being considered “subaltern citizens” or have frequently been an excluded community in post-colonial societies. They lack rights to land ownership and bureaucratic access. This article argues that Indonesian democracy has bred opposition between indigenous and migrant groups because, after the Reformation Era, migrants, as a minority, began to participate in popular politics to express themselves and make up their rights as “citizens”. Under the condition of democratic political participation, the Butonese found a way to mobilize their collective identity in order to claim the benefits of various governmental programs. Thus, this paper is about the contentiousness of how the rural Butonese migrants gained advantageous social and political status in the aftermath of the sectarian conflict between 1999 to 2003. Migrant’s ability to express their grievance in a constructive way through the politics of their representatives and state government policies have led to the new contentious issues between indigenous and migrant populations.

The history of the archive is the history of the state. Or so say conventional approaches to the archives. Until recently, the archive has been seen solely as a site, or rather a repository, of modern state power and governmentality, and a crucial medium for the making and preservation of national memory in the late 19th century. There is a truth to this state-centric perspective: the archive was conceived as a place where governments keep their records; they usually contain a term such as “state,” “government,” or “national” in their names; and they are often funded by and connected to a governmental body.

One of the more interesting aspects of world concern during “Operation Iraqi Freedom” was how to incorporate Iraq’s Kurdish population into an American military strategy. Furthermore, as the war was winding down, and the United States and Iraq began to construct a new Iraqi state, government, and Constitutional regime, the focus shifted on what role would the Kurds play in the new government, or even if they should be included in a government. But for most policy-makers, it was unclear who were the Kurds. How were they different than the other ethnic and religious populations of Iraq and the region generally? What was their history with the Iraqi regime under Saddam Hussein? The purpose of this paper is to provide answers to these most important questions through the lens of Political Science. As Iraq continues to form its new identity, it is important to understand what constitutes the identity of one of its most prominent ethnic groups, the Kurds. In tracing and describing Kurdish ethnic attributes, it is also important to delineate the history between the Iraqi government under Saddam Hussein, how Iraqi identity was constructed in opposition to Kurdish identity (often oppressing it), and to understand the tense relationship between the two, a relationship that is most aptly described as having a history of violence.

A study of the natural history of sickle hemoglobinopathies was begun in March 1979. By August 1987, a total of 2824 patients <20 years of age were enrolled. There have been 14 670 person-years of followup. Seventy-three deaths have occurred. Most of the deaths were in patients with hemoglobin SS. The peak incidence of death was between 1 and 3 years of age, and the major cause in these young patients was infection. Cerebrovascular accidents and traumatic events exceeded infections as a cause of death in patients > 10 years of age. There was limited success in identifying risk factors for death. Comparison of this study's overall mortality of 2.6% (0.5 deaths per 100 person-years) with previous reports indicates improvement of survival in US patients <20 years of age with sickle hemoglobinopathies. This improvement is most likely due to parental education and counseling about the illness and the early institution of antibotics in suspected infections.

This title has been used before, but usually with reference just to the conquest of Hong Kong by Japan in 1941, and here the battle for the territory is covered in a mere 20 pages. The main subject matter is indeed the Japanese occupation, but the title may be taken to have double reference because it is Snow's thesis that it was this brief period of less than four years that led inexorably to the handover of Hong Kong in 1997. He argues that the loss of Britain's imperial prestige was exacerbated and set in concrete by the clear message of post-1945 history that it was the Chinese who were the driving power behind Hong Kong and her development. Too weak (sometimes too insensitive) to take full economic advantage from events, the British presided over “an astonishing explosion of wealth. But in the process their own role had become so exiguous that it no longer really mattered, was indeed barely noticeable . . .“ This may be rather too harsh a judgement on the British (who in their ‘second innings’ hung on for more than half a century after all) but Snow is surely right in tracing the beginning of the distant end to the Japanese conquest which drew a line under received truths and cleared the way for the emergence of new attitudes on all sides.The political history of the pre-invasion period from the late 1930s, of the occupation itself, and of the immediate years after British resumption of control in August 1945 is nicely pieced together from a wide variety of sources, and Snow has tried hard to draw on Chinese, Japanese and Eurasian writings as well as on the much greater wealth of British accounts, both official and private. In this striving after balance he has had only limited success, the result still being an Anglocentric history, though certainly not entirely an Anglophile one. The problem is not of his making, but reflects the relatively sparse and unsystematic nature of sources available at present in Chinese especially.

There are conflicting psychiatric opinions about the value of separating depressive illnesses into several syndromes on clinical grounds, and so far experimental attempts to reach a classification of depression by distinguishing physiological or biochemical features which characterize one group rather than another have had only limited success. One interesting series of experiments in this area has been that of Shagass and his colleagues on the sedation threshold (Shagass et al., 1956, Shagass and Naiman, 1956, Shagass, 1954); they report that neurotic and psychotic depressions can be differentiated by means of EEG and other reactions to sodium amytal (amylobarbitone sodium) neurotics requiring greater amounts of the drug to reach the sedation threshold.
