This paper presents the design and science goals for the SkyMapper telescope. SkyMapper is a 1.3-m telescope featuring a 5.7-square-degree field-of-view Cassegrain imager commissioned for the Australian National University's Research School of Astronomy and Astrophysics. It is located at Siding Spring Observatory, Coonabarabran, NSW, Australia and will see first light in late 2007. The imager possesses 16 384 16 384 0.5-arcsec pixels. The primary scientific goal of the facility is to perform the Southern Sky Survey, a six-colour and multi-epoch (four-hour, one-day, one-week, one-month and one-year sampling) photometric survey of the southerly 2? sr to g ?23 mag. The survey will provide photometry to better than 3? global accuracy and astrometry to better than 50 milliarcsec. Data will be supplied to the community as part of the Virtual Observatory effort. The survey will take five years to complete. [ABSTRACT FROM AUTHOR]

Background. There is debate as to whether the elderly are really at lower risk for depressive disorders, or whether endorsement of symptoms is artefactually low. The present paper assesses the effects of age on anxiety and depression, and examines whether age has direct effects on self-report of individual symptoms independent of its effect on the underlying dimensions of anxiety and depression. Methods. Structural equation modelling was used to assess the structure of the items and their associations with age and a number of demographic variables. The sample of 2622 participants aged between 18 and 79 years from Canberra (Australia) was drawn from the Electoral Roll. Two instruments were used: the anxiety and depression scales of Goldberg et al. (1988) and the Personal Disturbance Scale from the DSSI of Bedford et al. (1976). Results. Both scales were found to fit satisfactorily to a two factor model. Age correlated negatively with depression. After controlling for the effects of gender, marital status, education and financial difficulty, direct effects of age were found on items from both instruments, indicating that certain depression items were associated with a differential probability of endorsement in older people, even when the level of depression was equal to that of younger people. Items with direct age effects reflected physical (feeling slowed down; waking early) and psychological (hopeless about the future) components of depression. Direct effects of age on items from both anxiety scales were also found. Conclusions. The nature of the depression and anxiety experienced by younger and older people may differ qualitatively. Depression may be associated with an increase in somatic symptoms linked to physical changes and to an increase in endorsement of items which reflect the narrowing of opportunities in the long-term.

ARCHITECTURAL design ,ARCHITECTURE competitions ,URBAN planning ,BUILDINGS - Abstract
Until the launch of Federation Square in Melbourne, in 1997, Australia's contribution to the history of international architectural competitions consisted essentially of two buildings: the Sydney Opera House, won by Jørn Utzon in 1957, and the Federal Parliament House in Canberra, won by Mitchell/Giurgola and Thorp (MGT) in 1980. While Utzon's building is widely acknowledged as a daring piece of innovative design and one of the architectural icons of this century, MGT's winning scheme for Parliament House drew heavy criticism from the moment the proposal was unveiled: neo-Classicist lines, a Beaux-Arts parti, and the building's occupation of Capital Hill at the top of the Griffins' 1912 scheme for Canberra were seen by many as displaying a lack of sensibility towards Australian landscape, culture, and ingenuity, and as the result of a conservative approach to contemporary urban design.

The article discusses the highlights of a seminar on animal welfare in wildlife management and conservation held at the CSIRO Discovery Centre in Canberra, Australian Capital Territory. The event carried a range of papers whose themes focused on humane management of unwanted wild animals, climate change and other topics related to animal welfare. A report was also introduced on cat ecology and management during the course of the seminar.

In contrast to the USA and the UK, vasectomy is less popular than tubal ligation in Australia, and this may reflect differences in husband-wife communication. Using data from the 1979 Canberra Population Survey, it seemed that although a majority of respondents would use sterilization, female sterilization would be preferred, largely because males were more resistant to the idea than females. Respondents born outside Australia, the UK, and Eire were more resistant to the idea of sterilization, but reported higher use of tubal ligation. [ABSTRACT FROM PUBLISHER]

Paolo Tombesi's intriguing article (7/2, pp140-154) on the genesis of Australia's Parliament House inevitably raises the question of possible comparisons with Scotland's Parliamentary saga. The differences, of course, are as striking as the similarities. Tombesi's position is that the Canberra building's design, which he dislikes, is explicable by the commissioning process, and the desire of the Australians to have reliability and delivery on time. Apart from the obvious formality of plan and pomposity of approach (although we are not altogether exempt from recent exemplars of either in twenty-first-century Britain), he takes it for granted that the architecture is entirely mediocre. Yet I would have been intrigued to know whether the spaces between the curved walls of the gathering spaces building and the Chambers and offices on either side, had any qualities.
