Quality-based benefit design in health insurance : the impact of a product benefit design change on the utilisation of oral health services by members of a private health insurance fund in regional and rural New South Wales, Australia

Objective: To examine the impact on dental utilisation following the introduction of a participating provider scheme (Regional and Rural Oral Health Program {RROHP)). In this model dentists receive higher third party payments from a private health insurance fund for delivering an agreed range of preventive and diagnostic benefits at no out-ofpocket cost to insured patients. Data source/Study setting: Hospitals Contribution Fund of Australia (HCF) dental claims for all members resident in New South Wales over the six financial years from l99811999 to 200312004. Study design: This cohort study involves before and after analyses of dental claims experience over a six year period for approximately 81,000 individuals in the intervention group (HCF members resident in regional and rural New South Wales, Australia) and 267,000 in the control group (HCF members resident in the Sydney area). Only claims for individuals who were members of HCF at 31 December 1997 were included. The analysis groups claims into the three years prior to the establishment of the RROHP and the three years subsequent to implementation. Data collection/Extraction methods: The analysis is based on all claims submitted by users of services for visits between 1 July 1988 and 30 June 2004. In these data approximately 1,000,000 services were provided to the intervention group and approximately 4,900,000 in the control group. Principal findings: Using Statistical Process Control (SPC) charts, special cause variation was identified in total utilisation rate of private dental services in the intervention group post implementation. No such variation was present in the control group. On average in the three years after implementation of the program the utilisation rate of dental services by regional and rural residents of New South Wales who where members of HCF grew by 12.6%, over eight times the growth rate of 1.5% observed in the control group (HCF members who were Sydney residents). The differences were even more pronounced in the areas of service that were the focus of the program: diagnostic and preventive services. Conclusion: The implementation of a benefit design change, a participating provider scheme, that involved the removal of CO-payments on a defined range of preventive and diagnostic dental services combined with the establishment and promotion of a network of dentists, appears to have had a marked impact on HCF members' utilisation of dental services in regional and rural New South Wales, Australia.

The legality of tissue transplants for the benefit of family members in the UK and Australia : implications for saviour siblings

The ethics of creating ‘saviour siblings’ for the benefit of another has received much attention, but little consideration has been given to the legal position of those saviours born who may be asked to provide tissue for transplantation to another during childhood. This article examines the ethical issues surrounding minor donation as well as the existing legal framework in the UK and Australia that regulates minors providing tissue for the benefit of another. Against this background the position of minor saviours, who are called upon to donate bone marrow or peripheral blood stem cells, is examined. This analysis suggests that the law does not provide sufficient protection for minor saviours who are called upon to donate to another. It is argued that specific ethical obligations are owed to saviours—that ought to be reflected in the law—in order to protect them from exploitation while they remain minors.

Investigating the influences on attendance and intention to rejoin with inaugural members of a new football team

This study investigated the effects of factors like member satisfaction and social rituals on desirable outcomes such as attendance, intention to rejoin and merchandise sales. This study focuses on the inaugural members of a new team in Australia’s A-League to gain insight into how loyalty develops amongst fans of new sporting organisations. The results show the importance to sports marketers of satisfying members and building ritual behaviour, as both are correlated with all of the positive outcomes investigated here.

Members abroad - Australia - Brisbane and the Gold Coast

Brisbane's sub-tropical climate, vegetation and urban history as a British settlement, endow the region with many characteristics that are familiar in KwaZulu-Natal. Brisbane settlement, firstly as a penal conlony to accommodate the hardiest criminals dispatched from Sydney, was established in 1825 on a wide river, several kilometers upstream from Moreton Bay with the Pacific Ocean beyond. The penal colony was short lived and was soon opened up to free settlement in 1842. The growth of the fledgling town was characterized by brick warehouse and service buildings to the port that was established on its riverbanks, resembling those of the old Point Road area in Durban. Government and administration buildings heralded Brisbane as the captial city of the State of Queensland, annexed from New South Wales in 1859. Morphological studies reveal that Brisbane had reached its first zenith around 1930 as a commerical city of four and five storey buildings. The urban form remained stagnant until the post-1960's building boom and the developments from this period on, consolidated land amalgamations largely ignoring the urban characteristics of the established city. Public space was poorly observed, resulting in a city that had turned its back on the river. It is only in recent times that the currency of good urban design, under the custodial direction of the City Council, has fostered a re-engagemed urban realm that, enabled by the recent building boom, has delivered high quality urban environments

Members abroad - Australia : Paul Sanders

I have been an academic since joining the University of Natal in 1998 and, following a period as a visiting lecturer in Brisbane in 2001, I joined the staff at QUT on an ongoing basis in 2003. I was appointed as Architecture Co-ordinator in 2006, and this role involves the leadership of the architectur discipline of 17 full time academics. I am currently enrolled in a PhD course in the field of urban morphology. This research proposes a theory on the relevance of mapping the evolutionary aspects of historical urban form to develop a measure for evaluating architecural elements and deriving parameters for new buildings. My participation in a QUT design team contributed to a recent successful invited competition bid for an Urban Transit Centre in Hangzhou, China. The Centre will include retail, business, entertainment, residential and service components at the heart of the Binjiang district on the 11.5ha core area with 32ha surrounding urban design precinct. The project has received the approval to commence and is to be implemented over the next three years!

When I arrived in Queensland's capital in 1996, Brisbane was commonly referred to as an 'overgrown country town'. This might have been an acceptable description in the 1990s, but it cannot be applied any longer. Brisbane, affectionaly referred to by the locals as Bris-Vegas, has now come of age. Following Sydney and Melbourne, Brisbane is the third most populous city in Australia with a population of approximately two million. Interestingly, the 2006 Census showed that 22 per cent of Brisbane's population was born overseas, the three main countries of birth being the UK, New Zealand and South Africa. Brisbane City is centred on its most dominant environmental element, the Brisbane River, which effectively carves Brisbane into two areas - the Northside and the Southside. The 2001 addition of Cox Rayner's Goodwill Pedestrian and Cycle Bridge signified Brisbane's acceptance and affectionate embrace of its River resulting in a long overdue linage between Brisbane's North and South. It connects the City's key precincts - the Northside CBD through Queensland University of Technology (QUT), across Brisbane River, to the recreational precinct of the Southside Southbank Parklands. The Southside cultural precinct of Southbank is the home to Queensland's Art Gallery, Performing Arts Complex, State Library and Museum -each of which were designed by Brisbane Stalwart Architect Robin Gibson, in the 1970s and '80s. The CBD component of the Brisbane River is flanked by a number of Institutional Facilities, including the campuses of QUT, Griffith University and the Southbank Education and Training Precinct (SETP), which combine to form a cross-river educational precinct. The past decade has born witness to a city which has keenly supported emerging architects in addition to the more entrenched stalwarts of the profession, resulting in a youthful, relaxed and unpretentious sub-tropical city. Viva Bris-Vegas!

Behaviour and design of cold-formed steel compression members at elevated temperatures

Cold-formed steel members have been widely used in residential, industrial and commercial buildings as primary load bearing structural elements and non-load bearing structural elements (partitions) due to their advantages such as higher strength to weight ratio over the other structural materials such as hot-rolled steel, timber and concrete. Cold-formed steel members are often made from thin steel sheets and hence they are more susceptible to various buckling modes. Generally short columns are susceptible to local or distortional buckling while long columns to flexural or flexural-torsional buckling. Fire safety design of building structures is an essential requirement as fire events can cause loss of property and lives. Therefore it is essential to understand the fire performance of light gauge cold-formed steel structures under fire conditions. The buckling behaviour of cold-formed steel compression members under fire conditions is not well investigated yet and hence there is a lack of knowledge on the fire performance of cold-formed steel compression members. Current cold-formed steel design standards do not provide adequate design guidelines for the fire design of cold-formed steel compression members. Therefore a research project based on extensive experimental and numerical studies was undertaken at the Queensland University of Technology to investigate the buckling behaviour of light gauge cold-formed steel compression members under simulated fire conditions. As the first phase of this research, a detailed review was undertaken on the mechanical properties of light gauge cold-formed steels at elevated temperatures and the most reliable predictive models for mechanical properties and stress-strain models based on detailed experimental investigations were identified. Their accuracy was verified experimentally by carrying out a series of tensile coupon tests at ambient and elevated temperatures. As the second phase of this research, local buckling behaviour was investigated based on the experimental and numerical investigations at ambient and elevated temperatures. First a series of 91 local buckling tests was carried out at ambient and elevated temperatures on lipped and unlipped channels made of G250-0.95, G550-0.95, G250-1.95 and G450-1.90 cold-formed steels. Suitable finite element models were then developed to simulate the experimental conditions. These models were converted to ideal finite element models to undertake detailed parametric study. Finally all the ultimate load capacity results for local buckling were compared with the available design methods based on AS/NZS 4600, BS 5950 Part 5, Eurocode 3 Part 1.2 and the direct strength method (DSM), and suitable recommendations were made for the fire design of cold-formed steel compression members subject to local buckling. As the third phase of this research, flexural-torsional buckling behaviour was investigated experimentally and numerically. Two series of 39 flexural-torsional buckling tests were undertaken at ambient and elevated temperatures. The first series consisted 2800 mm long columns of G550-0.95, G250-1.95 and G450-1.90 cold-formed steel lipped channel columns while the second series contained 1800 mm long lipped channel columns of the same steel thickness and strength grades. All the experimental tests were simulated using a suitable finite element model, and the same model was used in a detailed parametric study following validation. Based on the comparison of results from the experimental and parametric studies with the available design methods, suitable design recommendations were made. This thesis presents a detailed description of the experimental and numerical studies undertaken on the mechanical properties and the local and flexural-torsional bucking behaviour of cold-formed steel compression member at ambient and elevated temperatures. It also describes the currently available ambient temperature design methods and their accuracy when used for fire design with appropriately reduced mechanical properties at elevated temperatures. Available fire design methods are also included and their accuracy in predicting the ultimate load capacity at elevated temperatures was investigated. This research has shown that the current ambient temperature design methods are capable of predicting the local and flexural-torsional buckling capacities of cold-formed steel compression members at elevated temperatures with the use of reduced mechanical properties. However, the elevated temperature design method in Eurocode 3 Part 1.2 is overly conservative and hence unsuitable, particularly in the case of flexural-torsional buckling at elevated temperatures.
