A few good men: psychoanalysis, Abu ghraib and (the) American right

This essay proffers a psychoanalytic reading of the events of Abu Ghraib as deeply symptomatic of changes in American foreign policy and political culture. The paper examines the Lacanian understanding of group formation developed by Slavoj Zizek in his work on politics and culture (in Part I), and then applies this understanding to the Abu Ghraib scandal (Part II). In Part III, implications of the analysis are elaborated, in terms of Zizek's contention that the contemporary "permissive society" engenders in subjects the desire for new forms of mastery or "moral clarity".

Few choices under work choices

This paper sets out the history of the philosophical understanding held by the major political parties towards the governance of the Australian industrial relations system. In so doing it notes there has been a long legacy of socialist and conservative political and ideological support for mediating industrial conflict through the institutional agencies provided by conciliation and arbitration tribunals. The discussion notes the erosion of this legacy under the recent ascendancy of neo-liberal political and neo-classical economic thought, an ascendancy that has seen a significant retreat of state responsibility for mediating relations between the two sides of industry in the name of improving business productivity and national economic outcomes. The passing of the Workplace Amendment (Work Choices) Bill 2005 is the latest legislative manifestation of this thinking. This paper challenges the labour market assumptions and expectations of the Bill by arguing that equality in bargaining power between the two sides of industry in the manner afforded by conciliation and arbitration tribunals is essential for any genuine and lasting prosperity to exist between labour and capital.

Indigenous Australian accountants : why so few? A historical and cultural perspective

At a time when there is a growing call for Indigenous Australians to become self-sustainable and self-governing (Smith, 2002, Dodson & Smith, 2003, Martin, 2003) the very small number of Indigenous Australians in the accounting profession raises the question "why so few?" The number of Certified Practicing Accountants and Chartered Accountants of Australia is approximately 150,000 and to date only nine (9) qualified Indigenous Australian accountants have been located, representing 0.006%. This paper analyses the barriers faced by Indigenous Australians within the context of theories of cultral identity and colonisation of Australia. These theories are propounded as a means of exploring why there are so few Indigenous Australians represented in the accounting profession. An overview of colonial rule implemented by the British government from settlement of Australia in 1788, through to modern day Australia will be forwarded in an effort to draw out the implication of colonial rule on the development of Indigenous Australians whilst paying particular attention to the cultural identity of Indigenous Australians and the influence this has had on their career choices.

Chronological changes in tissue copper, zinc and iron in the toxic milk mouse and effects of copper loading

The toxic milk (tx) mouse is a rodent model for Wilson disease, an inherited disorder of copper overload. Here we assessed the effect of copper accumulation in the tx mouse on zinc and iron metabolism. Copper, zinc and iron concentrations were determined in the liver, kidney, spleen and brain of control and copper-loaded animals by atomic absorption spectroscopy. Copper concentration increased dramatically in the liver, and was also significantly higher in the spleen, kidney and brain of control tx mice in the first few months of life compared with normal DL mice. Hepatic zinc was increased with age in the tx mouse, but zinc concentrations in the other organs were normal. Liver and kidney iron concentrations were significantly lower at birth in tx mice, but increased quickly to be comparable with control mice by 2 months of age. Iron concentration in the spleen was significantly higher in tx mice, but was lower in 5 day old tx pups. Copper-loading studies showed that normal DL mice ingesting 300 mg/l copper in their diet for 3 months maintained normal liver, kidney and brain copper, zinc and iron levels. Copper-loading of tx mice did not increase the already high liver copper concentrations, but spleen and brain copper concentrations were increased. Despite a significant elevation of copper in the brain of the copper-loaded tx mice no behavioural changes were observed. The livers of copper-loaded tx mice had a lower zinc concentration than control tx mice, whilst the kidney had double the concentration of iron suggesting that there was increased erythrocyte hemolysis in the copper-loaded mutants.

Defining plant resistance against Phytophthora Cinnamomi and application of resistance to revegetation

Phytophthora cinnamomi is a soil borne plant pathogen that causes devastating disease in many Australian ecosystems and threatens the survival of native flora. Compared with the number of plant species that are susceptible to P. cinnamomi, only a few species are known to be resistant and control of this pathogen by chemicals is difficult and undesirable in natural systems. The major aim of our research is therefore to characterise natural resistance and determine which signalling pathways and defence responses are involved. Our examination of resistance is being approached at several levels, one of which is through the use of the model plant, Arabidopsis. Previously, Arabidopsis had been shown to display ecotypic variation in responses to P. cinnamomi and we are exploring this further in conjunction with the analysis of a bank of Arabidopsis defence pathway mutants for their responses to the pathogen. These experiments will provide a fundamental basis for further analysis of the defence responses of native plants. Native species (susceptible and resistant) are being assessed for their responses to P. cinnamomi at morphological, biochemical and molecular levels. This research also involves field-based studies of plants under challenge at various sites throughout Victoria, Australia. The focus of this field-based research is to assess the responses of individual species to P. cinnamomi in the natural environment with the goal of identifying individuals within susceptible species that display 'resistance'. Understanding how plants are able to resist this pathogen will enable strategies to be developed to enhance species survival and to restore structure and biodiversity to the ecosystems under threat.

Comparing experiments of the stressed skin diaphragm spanning several and few purlins

Concerning the specialty of the testing of stressed skin diaphragm assembly, the current loading method of cantilever beam test is improved by the diagonally loading method. In order to investigate the differences of the shear behavior between the stressed skins spanning several purlins and few purlins , which have the same forms and spaces of the connections and purlins, comparing experiments are carried out. Using the curve fitting method, the test results are quantified. The shear rigidity of two specimens is gained. It shows that the shear rigidity of the diaphragm spanning several purlins is quite higher than that spanning few purlins, but the carrying capacity of the former is a little lower than that of the latter.

Charismatic cops, patriarchs and a few good women : leadership, club culture and young peoples' drinking

The paper reports on key findings of a research project that examined the roles that communitybased
sporting clubs in the Australian state of Victoria play in shaping young people’s understandings and uses of alcohol. Our research imagined clubs as community hubs that are located in complex networks that impact on the ways that clubs understand their locations in communities, and which have unpredictable influences and consequences on club histories, culture and orientations to issues such as young people and alcohol use. The paper focuses on understanding the key roles played by club leaders in facilitating change and transformation in these contexts, particularly in terms of alcohol-related practices and the potential impact of these on young people’s uses and understanding of alcohol. We situate these findings in a framework that draws on the literature of complexity science and complex adaptive systems (CAS) to suggest that these practices and changes need to be understood in ways that allow for complexity, uncertainty, emergent behaviours and adaptive change.

Genetic control of male fertility in Arabidopsis thaliana : structural analysis of postmeiotic developmental mutants

Seven new male-sterile mutants (ms7–ms13) of Arabidopsis thaliana (L.) Heynh. (ecotype columbia) are described that show a postmeiotic defect of microspore development. In ms9 mutants, microspores recently released from the tetrad appear irregular in shape and are often without exines. The earliest evidence of abnormality in ms12 mutants is degeneration of microspores that lack normal exine sculpturing, suggesting that the MS12 product is important in the formation of pollen exine. Teratomes (abnormally enlarged microsporocytes) are also occasionally present and each has a poorly developed exine. In ms7 mutant plants, the tapetal cytoplasm disintegrates at the late vacuolate microspore stage, apparently causing the degeneration of microspores and pollen grains. With ms8 mutants, the exine of the microspores appears similar to that of the wild type. However, intine development appears impaired and pollen grains rupture prior to maturity. In ms11 mutants, the first detectable abnormality appears at the mid to late vacuolate stage. The absence of fluorescence in the microspores and tapetal cells after staining with 4′,6-diamidino-2-phenylindole (DAPI) and the occasional presence of teratomes indicate degradation of DNA. Viable pollen from ms10 mutant plants is dehisced from anthers but appears to have surface abnormalities affecting interaction with the stigma. Pollen only germinates in high-humidity conditions or during in-vitro germination experiments. Mutant plants also have bright-green stems, suggesting that ms10 belongs to the eceriferum (cer) class of mutants. However, ms10 and cer6 are non-allelic. The ms13 mutant has a similar phenotype to ms10, suggesting is also an eceriferum mutation. Each of these seven mutants had a greater number of flowers than congenic male-fertile plants. The non-allelic nature of these mutants and their different developmental end-points indicate that seven different genes important for the later stages of pollen development have been identified.

Genetic control of male fertility in Arabidopsis thaliana : structural analysis of premeiotic developmental mutants

We have taken a mutational approach to identify genes important for male fertility in Arabidopsis thaliana and have isolated a number of nuclear male/ sterile mutants in which vegetative growth and female fertility are not altered. Here we describe detailed developmental analyses of four mutants, each of which defines a complementation group and has a distinct developmental end point. All four mutants represent premeiotic developmental lesions. In ms3, tapetum and middle layer hypertrophy result in the degeneration of microsporocytes. In ms4, microspore dyads persist for most of anther development as a result of impaired meiotic division. In ms5, degeneration occurs in all anther cells at an early stage of development. In ms15, both the tapetum and microsporocytes degenerate early in anther development. Each of these mutants had shorter filaments and a greater number of inflorescences than congenic male-fertile plants. The differences in the developmental phenotypes of these mutants, together with the non-allelic nature of the mutations indicate that four different genes important for pollen development, have been identified.

Primary T-lymphocytes rescue the replication of HIV-1 DIS RNA mutants in part by facilitating reverse transcription

The dimerization initiation site (DIS) stem-loop within the HIV-1 RNA genome is vital for the production of infectious virions in T-cell lines but not in primary cells. In comparison to peripheral blood mononuclear cells (PBMCs), which can support the replication of both wild type and HIV-1 DIS RNA mutants, we have found that DIS RNA mutants are up to 100 000-fold less infectious than wild-type HIV-1 in T-cell lines. We have also found that the cell-type-dependent replication of HIV-1 DIS RNA mutants is largely producer cell-dependent, with mutants displaying a greater defect in viral cDNA synthesis when viruses were not derived from PBMCs. While many examples exist of host–pathogen interplays that are mediated via proteins, analogous examples which rely on nucleic acid triggers are limited. Our data provide evidence to illustrate that primary T-lymphocytes rescue, in part, the replication of HIV-1 DIS RNA mutants through mediating the reverse transcription process in a cell-type-dependent manner. Our data also suggest the presence of a host cell factor that acts within the virus producer cells. In addition to providing an example of an RNA-mediated cell-type-dependent block to viral replication, our data also provides evidence which help to resolve the dilemma of how HIV-1 genomes with mismatched DIS sequences can recombine to generate chimeric viral RNA genomes.

Professional legal education reviews : too many 'what's, too few 'how's

Former colonies of the British Empire, Hong Kong and Australia inherited the common law system and the basic structure of legal education and training from England and Wales and remain the closest siblings in terms of proximity in distance and the high degree of similarity between their respective frameworks for legal education and training. This article first summarizes the major reviews of legal education and training in these three jurisdictions: England and Wales, Australia and Hong Kong over the last four decades and argues that while these reviews are keen on investigating ‘what’ is lacking in the curriculum and ‘what’ needs to be changed to equip graduates for the challenges of the day, they do not seem to have shown the same level of enthusiasm in identifying ‘how’ the intended outcomes prescribed can be achieved. Nevertheless, law schools in these jurisdictions recently began to tap on, and combine with the improved classroom pedagogy, clinical legal education and internship, innovative teaching tools and solutions in an attempt to deliver more enhanced learning experience to students. The article examines the role ascribed to technology in legal education and training with a particular reference to SimPLE, a e-learning platform developed in England and Wales which has been put to use in Australia as well, and the reform initiatives taken, and planned to be taken, by the Department of Professional Legal Education at the University of Hong Kong in its Postgraduate Certificate in Laws programme. This article concludes by pointing out the importance of collaboration among stakeholders including teachers, university administration and the legal profession in effecting a more active role of technology in legal education and training of today.
