The contagious magic of James Cook in Captain-Cook's cottage

It is widely known that the so-called Cooks' Cottage in Fitzroy Gardens, relocated from Yorkshire to Melbourne in 1934, was never inhabited by Captain James Cook. Yet a subliminal nationalism, sustained by the ancient traditions of contagious magic, feeds the conviction that the dwelling must be directly connected to Australia's foundation hero — a relic that the great man touched — or else it is meaningless. This paper tracks a sequence of managerial–interpretive strategies derived from a chronology of knowledge systems to make meanings at the cottage. It introduces evidence of the original shape of the building in its Great Ayton location, and observes the consequences on management and interpretation of an older demolition and consequent rebuilding of only half the cottage in Melbourne. Much turns on changing ideas about authenticity, as management strategies fail to engage the popular taste for a hero via the magic of faith. The result is a set of opposing principles in presenting the cottage: the role of the historical record as it has enlarged, and the desires of visitors who expect a simple connection between myth and materiality.

Structural and biochemical characterisation of the oxidoreductase NmDsbA3 from Neisseria meningitidis

DsbA is an enzyme found in the periplasm of Gram-negative bacteria that catalyses the formation of disulfide bonds in a diverse array of protein substrates, many of which are involved in bacterial pathogenesis. Whilst most bacteria possess only a single essential DsbA, Neisseria meningitidis is unusual in that it possesses three DsbAs, although the reason for this additional redundancy is unclear. Two of these N. meningitidis enzymes (NmDsbA1 and NmDsbA2) play an important role in meningococcal attachment to human epithelial cells, whilst NmDsbA3 is considered to have a narrow substrate repertoire. To begin to address the role of DsbAs in the pathogenesis of N. meningitidis, we have determined the structure of NmDsbA3 to 2.3 Å resolution. Although the sequence identity between NmDsbA3 and other DsbAs is low, the NmDsbA3 structure adopted a DsbA-like fold. Consistent with this finding, we demonstrated that NmDsbA3 acts as a thiol-disulfide oxidoreductase in vitro and is reoxidised by Escherichia coli DsbB (EcDsbB). However, pronounced differences in the structures between DsbA3 and EcDsbA, which are clustered around the active site of the enzyme, suggested a structural basis for the unusual substrate specificity that is observed for NmDsbA3.

Admissible Christianity : a study of Christian fundamentalism in the writings of James Barr

An attempt to set forth the essential nature of a theology is a notoriously difficult task. This thesis addresses two questions to a contemporary study of fundamentalism. It asks to what extent has James Barr been able to describe the theology of fundamentalism and to what extent his critical analysis of that theology is philosophically valid? The first chapter identifies the inherent difficulties in a phenomenology of fundamentalism and includes an historical survey of the theology of the movement. This chapter is supported by appendix one which identifies the philosophical culture associated with fundamentalist thought. Barr's description of the theological and religious character of fundamentalism is accepted within the identified limitations. The second and third chapters give an account of Barr's theological evaluation of fundamentalism. He argues the fundamentalists espouse an aberrant form of Christianity. Their religion represents a projection onto the biblical text of a religion foreign to the theological character of the Old and New Testaments. This projection is achieved by an intellectually sophisticated hermeneutical procedure. The doctrines of inerrancy, verbal inspiration and infallibility establish an understanding of Christianity which does not represent the essential character of the Christian faith. Fundamentalist hermeneutics, Barr concludes, allows for a theology indigenous neither to the biblical text nor to the Christian tradition. It attempts to afford biblical justification to the doctrines of a human religion extraneous to the biblical text. The fourth chapter considers the philosophical basis of Barr's understanding of the Bible. He takes the idealist view that the biblical text possesses a theological meaning whose boundaries can be delineated and whose essential content defined. This chapter is supported by appendix two which locates Barr's writings on fundamentalism within his wider concerns about the hermeneutical problems raised by the biblical text and the religious authority of the Bible. The penultimate chapter surveys the insights of contemporary literary theory concerning the perception of written texts. The philosophical validity of an idealist view of the biblical text is questioned. Two major conclusions are drawn. Barr's assessment of fundamentalism is philosophically dependent upon his idealist perception of the biblical text. This conclusion leads to the more general conclusion that the biblical text contains no essential description of Christianity but is capable of being read according to a range of theological interpretations some of which are more defensible than others.

Monitoring the marine environment adjacent to a petroleum refinery on Corio Bay, Victoria, Australia /Peter James Gilbert

The objective of the work reported in this thesis was to design and implement an ecological effects environmental monitoring program which would: 1) Collect baseline biological information on sessile epibiotic fouling communities from an area adjacent to a petroleum refinery located on Corio Bay, Victoria, to allow comparison with results of future monitoring for the assessment of long term temporal water quality trends. 2) Detect and — if possible - estimate the magnitude of any influence on epibiotic fouling communities within the Corio Bay marine ecosystem attributable to operations at the Shell Petroleum Refinery. 3) Investigate the extent of thermal stratification and rate of dispersal of the petroleum refinery main cooling-water outfall plume (discharging up to 350,000 tonnes of warmed seawater per day), and its effect on epibiotic communities within the EPA-defined mixing zone. A major component of the work undertaken was the design and development of artificial-substrate biological sampling stations suitable for use under the conditions prevailing in Corio Bay, and the development of appropriate quantitative underwater photographic sampling techniques to fulfil the experimental criteria outlined above. Experimental and other constraints imposed on the design of the stations precluded the simple suspension of frames from jetties or pylons, a technique widely used in previous work of this type. Artificial substrate panels were deployed along three radial transects centred within and extending beyond the petroleum refinery main cooling-water mixing zone. Identical substrate panels were deployed at a number of control sites located throughout Corio Bay, each chosen for differences in their degree of exposure to such factors as water movement, depth, shipping traffic and/or comparable industrial activity. The rate of colonisation (space utilisation) and the development of epibiotic fouling communities on artificial substrate panels was monitored over two twelve-month sampling periods using quantitative underwater photographic sampling techniques. Sampling was conducted at 4-8 week intervals with the rate of panel colonisation and community structure determined via coverage measurements. Various species of marine algae, polychaete tubeworms, hydroids, barnacles, simple and colonial ascidians, sponges, bivalve molluscs and encrusting bryozoans were all detected growing on panels. Communities which established on panels within the cooling-water mixing-zone and those at control sites were compared using statistical procedures including agglomerative hierarchical cluster analysis. A photographic sample archive has been established to allow comparison with similar future studies.
