Gustav Holst and British Music Society of Victoria collections at the State Library of Victoria

The paper presents a content-based evaluation, tracing the historical background of two heritage music collections at the State Library of Victoria (Melbourne, Australia).  In the case of the Gustav Holst and the British Music Society of Victoria Collections, history and content intertwine for the reason that both collections were initiated at the same time and by the same visionary power. During the early 1930s Louise Hanson-Dyer, a patron of Gustav Holst, issued a complete catalogue of the composer’s works and donated to the State Library of Victoria the first batch of Holst scores. This was to be the initial installment of a complete collection of published British music, which, however, was stopped due to duty tax complications. At the same time, the British Music Society of Victoria, founded by Louise Hanson-Dyer in 1921, maintained the first open library of chamber music in Australia. The BMS of Victoria Collection came to the State Library of Victoria in the 1980s. The most valuable materials in the collection are manuscripts of Australian twentieth century works, concert programs and first publications of British music from the 1920s and 1930s, which also supplement the Gustav Holst Collection. The collections are valuable reference and research collections, which document musical taste and music-making in Melbourne from 1920s well into the 1970s. The collections are also sources for studies into Louise Hanson-Dyer’s gift in collection development and her efforts to raise the professional standards of music performance in Melbourne and Australia.

Publishing dynamic state changes of resources through state aware WSDL

A common architecture in today's development of distributed systems is the service-oriented architecture (SOA) implemented using Web services. Until recently, it was difficult to build a SOA based grid/distributed system using Web services due to the inability to learn the state of services. The state of a Web service could only be accessed through specialized clients and/or services. Should the specialized client or service fail, the state can't be accessed. This paper shows the innovative resources via Web instances (RVWI) framework. RVWI grants to web services the ability to show the state of dynamic resources in their WSDL. This was achieved via software components called connectors which watch for any changes in a resource and updates the web service. The significance of this report is the support for resources which can change state between requests and the innovation is the improvement of state updates between the service and discovery services.

Solid state recycling of 5083 Al alloy by hot extrusion

The machined chips of 5083 Al alloy were recycled by hot extrusion at 723 K with an extrusion ratio of 44:1 in air. Corrosion and mechanical properties of the recycled specimens have been compared with those of a virgin extrusion which was processed from the ingot block. As a result of salt immersion tests, mass loss of the recycled specimen was not less than twice of that of the virgin extrusion. The deterioration in corrosion properties for the recycled specimen was attributed to the excessive contamination of Fe which promoted galvanic corrosion. As a result of tensile tests, the recycled specimen exhibited a good combination of high strength and high elongation to failure at room temperature. The excellent mechanical properties for the recycled specimen were attributed to the refined microstructure. However, the elongation to failure of the recycled specimen at elevated temperatures more than 573 K was lower than that of the virgin extrusion. The contamination of oxide particles is likely to be responsible for the lower elongation in the solid recycled specimen.

Predicting time trade-off health state valuations of adolescents in four Pacific countries using the assessment of quality-of-life (AQoL-6D) instrument

Objectives: Pacific Obesity Prevention in Communities (OPIC) is a community-based intervention project targeting adolescent obesity in Australia, New Zealand, Fiji, and Tonga. The Assessment of Quality of Life Mark 2 (AQoL-6D) instrument was completed by 15,481 adolescents to obtain a description of the quality of life associated with adolescent overweight and obesity, and a corresponding utility score for use in a cost–utility analysis of the interventions. This article describes the recalibration of this utility instrument for adolescents in each country.

Methods: The recalibration was based on country-specific time trade-off (TTO) data for 30 multiattribute health states constructed from the AQoL-6D descriptive system. Senior secondary students, in a classroom setting, responded to 10 health state scenarios each. These TTO interviews were conducted for 24 groups, comprising 279 students in the four countries resulting in 2790 completed TTO scores. The TTO scores were econometrically transformed by regressing the TTO scores upon predicted scores from the AQoL-6D to produce country-specific algorithms. The latter incorporated country-specific “corrections” to the Australian adult utility weights in the original AQoL.

Results: This article reports two methodological elements not previously reported. The first is the econometric modification of an extant multi-attribute utility instrument to accommodate cultural and other group-specific differences in preferences. The second is the use of the TTO technique with adolescents in a classroom group setting. Significant differences in utility scores were found between the four countries.

Conclusion: Statistical results indicate that the AQoL-6D can be validly used in the economic evaluation of both the OPIC interventions and other adolescent programs.

High-temperature laser-scanning confocal microscopy as a tool to study the interface instability during unsteady-state solidification of low-carbon steel

Solidification microstructure is a defining link between production techniques and the mechanical properties of metals and in particular steel. Due to the difficulty of conducting solidification studies at high temperature, knowledge of the development of solidification microstructure in steel is scarce. In this study, a laser-scanning confocal microscopy (LSCM) has been used to observe in situ and in real-time the planar to cellular to dendritic transition of the progressing solid/liquid interface in low carbon steel. Because the in situ observations in the laser-scanning confocal microscopy are restricted to the surface, the effect of sample thickness on surface observations was determined. Moreover, the effect of cooling rate and alloy composition on the planar to cellular interface transition was investigated. In the low-alloyed, low-carbon steel studied, the cooling rate does not seem to have an effect on the spacing of the cellular microstructure. However, in the presence of copper and manganese, the cell spacing decreased at higher cooling rates. Higher concentrations of copper in steel resulted on an increased cell spacing at the same cooling rates.

Greeting the state: entanglements of custom and modernity on Papua New Guinea’s Rai Coast

In May 2010, a delegation of Papua New Guinean politicians travelled to a remote village on the country’s north coast to receive a petition against proposed mine activity. The encounter between the politicians and the villagers who had invited them involved two very different articulations of power and authority, and two competing cartographies of centrality and marginality. The encounter speaks to the need to approach the concepts of custom and modernity not only as powerful discourses which are taken up and performed in local places, but also as analytical descriptors of actually existing patterns of practice and meaning which are structurally and ontological distinct. At the same time, however, analysis of the encounter between villagers and politicians makes clear that this structural difference cannot be written straightforwardly onto the social bodies of opposing collectivities. Rather, customary and modern forms of social relations exist in dynamic and ambivalent entanglements, pulled into contingent and differently weighted configurations by actors in local places.

North Korean human rights and the international community: responding to the UN Commission of Inquiry

Of all the difficult conversations to have with the Democratic People’s Republic of Korea (DPRK) regime, the one over human rights has proven the most troubling for the international community. Once human rights issues are placed on the table, diplomatic efforts become quickly de-railed. Because of this, and because issues such as non-proliferation are seen as more pressing than human rights, there has been a conspicuous absence of any official, systematic response to the question of human rights violations in North Korea. Of course, most human rights campaigns experience some amount of politicisation. This is unsurprising, given the deeply political nature of the very concept of human rights. The North Korean human rights issue, however, suffers from this phenomenon more than most, tied up as it is with wider ideological battles that hark back to the circumstances of the division of the Korean peninsula. In this context, the 2014 report delivered by the United Nations (UN) Commission of Inquiry (COI) into North Korean human rights represents an effort to move above and beyond the politicisation of the issue and was largely successful in this regard.

Reduced order functional observers with application to partial state estimation of linear systems with input delay

Reduced order multi-functional observer design for multi-input multi-utput (MIMO) linear time-invariant (LTI) systems with constant delayed inputs is studied. This research is useful in the input estimation of LTI systems with actuator delay, as well as system monitoring and fault detection of these systems. Two approaches for designing an asymptotically stable functional observer for the system are proposed: delay-dependent and delay-free. The delay-dependent observer is infinite-dimensional, while the delay-free structure is finite-dimensional. Moreover, since the delay-free observer does not require any information on the time delay, it is more practical in real applications. However, the delay-dependent observer contains less restrictive assumptions and covers more variety of systems. The proposed observer design schemes are novel, simple to implement, and have improved numerical features compared to some of the other available approaches to design (unknown-input) functional observers. In addition, the proposed observers usually possess lower order than ordinary Luenberger observers, and the design schemes do not need the observability or detectability requirements of the system. The necessary and sufficient conditions of the existence of an asymptoticobserver in each scenario are explored. The extensions of the proposed observers to systems with multiple delayed-inputs are also discussed. Several numerical examples and simulation results are employed to support our theories.
