Optical studies of two LMC X-ray transients : RX J0544.1-7100 and RX J0520.5-6932

We report observations which confirm the identities of the optical counterpart to the transient sources RX J0544.1-7100 and RX J0520.5-6932. The counterparts are suggested to be a B-type stars. Optical data from the observations carried out at ESO and SAAO, together with results from the OGLE data base, are presented. In addition, X-ray data from the RXTE all-sky monitor are investigated for long term periodicities. A strong suggestion for a binary period of 24.4d is seen in RX J0520.5-6932 from the OGLE data.Comment: 6 pages, 7 figure

Joint industry planning platforms for coal export supply chains

Improving the performance and reducing the costs associated with export logistics chains is critical to the competitiveness of export coal mines. The fundamental practices associated with the use of export logistics chains made up of mine, trucking, rail and port operations are being challenged by the advent of third party operators on rail systems and the use of the Internet. Whilst individual mines can improve their processes to drive down their mining costs, they face major challenges in their endeavour to improve the performance of export logistics chains and reduce the significant logistics costs of moving coal from the mine to export ships, via the shared infrastructure of rail systems and ports. There is an increasing realisation that global competition is not only between mines but between coal export regions that are defined by their rail system and ports infrastructure. The development and use of a joint industry planning platform for the export logistics chains of the Western Australian Grain Industry has demonstrated that an industry facing significant restructuring and increased competitiveness can achieve major throughput and cost reduction gains when stakeholders in export logistics chains share key planning information using the Internet and state of the art planning tools. Joint industry planning platforms for export logistics chains are being considered or are at initial stages of development for a number of Australasian coal export logistics chains. This paper reviews the development of a joint industry platform for the W A Grain industry and reports on the state of development of similar planning platforms for the export logistics chains of the Illawarra, Hunter Valley, SE Queensland, Blackwater / Moura. Goonyella and Mt Isa / Townsville export coal regions. This paper addresses the key components of joint industry planning platforms, the key information that should be shared, the use of the internet and information servers, and the contractual Structures required to enable stakeholders of an export logistics chain,w ho are competitors or potential competitors, to work together to improve the competitiveness of a coal export region

Riding the seismic waves: Re-blending teacher education in response to changing demands

Editors: G. Williams, P. Statham, N. Brown & B. Cleland ISBN Proceedings USB: 978-1-86295-644-5 published by the University of TasmaniaBlended learning plays an important role in many tertiary institutions but little has been written about the implementation of blended learning in times of adversity, natural disaster or crisis. This paper describes how, in the wake of the 22 February Canterbury earthquake, five teacher educators responded to crisis-driven changing demands and changing directions. Our narratives describe how blended learning provided students in initial teacher education programmes with some certainty and continuity during a time of civil emergency. The professional learning generated from our experiences provides valuable insights for designing and preparing for blended learning in times of crisis, as well as developing resilient blended learning programmes for the future

Trust in international joint venture relationships

A great deal of attention has been paid to the performance of international joint ventures (IJVs) and trust has been recognised as a key factor influencing it. This paper examines the emergence of trust as a process and develops a process model of trust building in IJVs, which is used to analyse four case studies. The main conclusions are the following: Whereas competence-based trust starts from public information, promissory-based trust and goodwill-based trust are individually orientated and mainly develop through direct personal interaction. Such interaction may lead to bonds of friendship between delegates. Before these bonds evolve, trust is mainly based on the perceived self-interest of the partner in the joint venture. When the bonds of friendship dominate, the main source of trust shifts towards emotional commitments. Thus, in the early stages of an IJV, promissory-based trust predominates, and as the joint venture progresses, competence-based trust emerges. Goodwill-based trust is important throughout the process. A commitment to cooperate emerges from initial self-interest. The model is capable of further development and testing
