Green planning heritage/industrial nature : the park lands or 'regeneration reserves' of Broken Hill

Freestone (1989+) has extensively surveyed town planning visions and model communities for Australia, but one settlement has been forgotten. The significant mining settlement of Broken Hill in far western New South Wales does not figure in his thematic and historical analyses yet its park lands are so integral to its physical cultural legacy and human health that it warrants enhanced standing. In the last 2 years the Commonwealth has been considering the potential nomination of the municipality of Broken Hill for inclusion onto the National Heritage List principally due to its mining, social and economic contributions to Australia’s heritage and identity. A component in their deliberations is the Park Lands, or ‘Regeneration Reserves’, that encompass this urban settlement and its mine leaseholds. Within these Regeneration Reserves, international arid zone ecological restoration theory and practice was pioneered by Albert and Margaret Morris in the 1930s that serves as the method for all mining revegetation practice in Australia today. This paper reviews the theory and evolution of the Broken Hill Regeneration Reserves, having regard to the Adelaide Park Lands and Garden City discourses of the 1920s-30s, arguing that the Broken Hill Regeneration Reserves have a valid and instrumental position in the planning and landscape architectural histories of Australia.

Performing the technical image

The recent public multi-screen performance of formalist experimental animation by film artists such as Guy Sherwin, Bruce McLure and Greg Pope respond to the immediacy and speed of new digital technologies, the rise of Vilem Flusser’s ‘technical image’ and the consequent disappearance of reflective space identified by Prensky, Kroker, Virilio and Postman. Flusser’s ‘technical images’, benefiting from the digital’s painterly hyper-malleability structure and content, signifier and signified, so much the subject of Peter Gidal’s arguments in support of his concept of ‘materialist film’ in the 1970’s.  In the digital those formal editing strategies used to create the ‘technical image’ within analogue image construction that traditionally took place in the artist’s studio within the camers and optical printer are now executed inside the computer, having migrated into the post-production process.  Within the work of these artist’s recent multi-screen presentations these manipulations are now-elusively experienced in live ephemeral performance, re-forming and laying bare those processes that have been rendered invisible in digital technology.  The significance of this work partly lies in its ability to communicate historical information a-historically. Guy Sherwin and Lynn Loo’s method in their play with 16mm film flashes and after-images and Sherwin’s mirror performance further reproduces Goethe’s method from his Theory of Colours (1840). Greg Pope’s scratch performances re-enact the operation of Konrad Zuse’s 1930’s computing machine. Affinities are drawn between Bruce McLure’s immersive overpowering sonic and flicker performances with Edwin Land’s 1960’s experiments on colour constancy on which Land’s Retinex Theory of colour is based.

Technical factors for implementing SOA-Based business intelligence architecture : an exploratory study

Business intelligence (BI) architecture based on service-oriented architecture (SOA) concept enables enterprises to deploy agile and reliable BI applications. However, the key factors for implementing a SOA-based BI architecture from technical perspectives have not yet been systematically investigated. Most of the prior studies focus on organisational and managerial perspectives rather than technical factors. Therefore, this study explores the key technical factors that are most likely to have an impact on the implementation of a SOA-based BI architecture. This paper presents a conceptual model of BI architecture built on SOA concept. Drawing on academic and practitioner literature related to SOA and software architectural design, we propose fourteen key factors that may influence the implementation of a SOA-based BI architecture. This study bridges the gap between academic and practitioners.

Impaction bone grafting of the glenoid in revision shoulder arthroplasty : classification, technical description and early results

Background Glenoid component fixation remains an issue in the long-term survival of total shoulder arthroplasty. As a consequence revision of the glenoid component is becoming increasingly more common and reconstructive techniques to preserve and restore bone stock are becoming more important.

Methods In this article we describe the combined technique of impaction grafting and glenoid component exchange together with a classification of the glenoid defect with a report on four sequential cases in patients with rheumatoid arthritis with an average age of 56 years. The minimum follow-up was 34 months (range 34 months to 62 months).

Results Patients reported excellent pain relief and some improvement in motion and function. The complication rate remains low. Radiological assessment using tomograms showed good incorporation of the bone graft and minimal signs of glenoid loosening.

Conclusion The results of this study confirm that at least in the short term impaction grafting techniques used to reconstitute the glenoid in revision surgery can be successful.

Making sense of business intelligence : proposing a socio-technical framework for improved decision making in not-for-profit organisations

The authors of this paper argue that human intuition alone cannot be relied upon for strategic decision making in today’s business environment and that quality data intelligence is an imperative. The proposed project described in this paper is research-in-progress, action design research (ADR), to implement an appropriate information systems (IS) enabling enhanced organisational decision making. ADR is a new research method that draws on action research and design research in an organisational setting. In phase 1 of the project, a sociotechnical ‘sense-making’ approach is used to gather and analyse information and decision needs in a not-for-profit (NFP) association, Connections ACT. In phase 2, requirements are designed and modelled to build a conceptual framework that guides NFPs in improving business performance and reporting capability. Phase 3 is the evaluative stage when the framework is reflected upon and refined, with intervention in the organisation’s processes as a promising outcome.

Blind alleys, blinding and blinded aliens : mapping the outer limits of the technical image

Marcia Jane's installation work is situated along a historic line of critical enquiry traceable back to Goethe. her energy field series re-tools for digital use the formal erasures of sturcturalist film, where the relationship between the signifier and the signified are inverted.
