    Journal Article
    The core of OMC-1 has been imaged with the Near-Infrared Camera and Multiobject Spectrometer (NICMOS) on board the Hubble Space Telescope at 0 2 resolution in 1% filters at 2.12 and 2.15 μm, revealing intricate structures in both continuum and shocked molecular hydrogen line emission. Numerous H -emitting clumps surrounding the BN/KL region have been resolved for the first time, several of which exhibit prototypical bow-shock morphologies with -shaped tips. We interpret these to be lower excitation analogs of similar structures 2 northwest of the core observed with ground-based telescopes. Many of the elongated H structures and bow-shock features appear to radiate outward from a region within a few arcseconds of radio source I, which suggests that the H energetics are dominated by one or more outflow sources in this region. However, the orientations of some features are unrelated to this apparent outflow pattern. The deeply embedded, suspected outflow source I remains undetected at 2 μm, although two faint new continuum sources have been detected within 1 of it. The newly resolved H features with bow-shock morphologies are located in regions previously identified as bow shocks by highly blueshifted components in their line profiles. In contrast, regions of H emission that are diffuse in the NICMOS image have broad, smooth line profiles. Several continuum features have an arclike appearance, which suggests interactions of winds with the ambient medium. At least 40 stellar or protostellar continuum sources have been detected, including at least one proplyd and four pairs of binary stars.

    Conference Paper
    The core of OMC--1 has been imaged with NICMOS on the Hubble Space Telescope at 0.2'' resolution in 1% filters at 2.12 and 2.15mu m, revealing intricate structures in both continuum and shocked molecular hydrogen line emission. Numerous H_2-emitting clumps surrounding the BN/KL region have been resolved for the first time, several of which exhibit prototypical bow-shock morphologies with V-shaped tips. We interpret these to be lower-excitation analogs of similar structures ~ 2' NW of the core observed with ground based telescopes. Many of the elongated H_2 structures and bow-shock features appear to radiate outward from a region within a few arcseconds of radio source 'I', suggesting that the H_2 energetics are dominated by one or more outflow sources in this region. However, the orientations of some features are unrelated to this apparent outflow pattern. The deeply embedded, suspected outflow source `I' remain s undetected at 2 mu m, although two faint new continuum sources have be en detected within ~ 1'' of it. The newly resolved H_2 features with bow-shock morphologies are located in regions previously identified as bow-shocks by highly blueshifted components in their line profiles. Several continuum features have an arc-like appearance, suggesting interactions of winds with the ambient medium. At least 40 stellar or protostellar continuum sources have been detected, including at least one proplyd and four pairs of binary stars.

    Journal Article
    This essay is based on the seventeenth annual D. F. McKenzie lecture given at the University of Oxford on 2 March 2011. McKenzie is best known for his tolerant unrolling of the bibliographical into wider cultural and social realms, together with his implication that the material book can be treated as an index of them. Eggert’s essay argues for a timely counterbalance: the need for a regathering of the concept of the work, which largely fell from view during the period of high literary theory. A new model for interpretation is proposed by building reading, and thus the aesthetic, into the definition of the work, while retaining the evidentiary witness of the material book. The model offers, in other words, a justification for folding book history and bibliography into the literary study of all works that have enjoyed an extended history of printing and reprinting.

    Thesis
    The problem investigated by this thesis is the Self Containment Policy for munitions supply in Australia 1901-1945. The thesis examines how the policy was applied, and whether it succeeded in its goal of securing munitions supply in Australia during a major conflict. The procedures followed have been to examine the records of the Department of Defence, the Department of Supply and Development, and the Department of Munitions. The records of other federal government departments were also investigated to supplement the documentary record contained in the first three departments. Personal papers in the Australian War Memorial, and National Library of Australia were also utilised to fill in gaps in knowledge. A significant number of personal interviews with surviving figures of the Self Containment Policy were also a valuable source of information. Newspapers were used sparingly. The Self Containment Policy was hardly ever a public issue, and was usually incorrectly reported by the public media. Secondary published sources were not especially helpful. The Self Containment Policy has never been of much interest to historians and scholars. It has been possible to write a detailed account of the politics and administration of the Self Containment Policy. The policy as administered by the Munitions Supply Board, was well thought out, and ultimately successful in supplying the quantity and quality of munitions required for the defence of Australia during the Second World War.
