Patterns of change and stability in the gender division of household labour in Australia, 1986-1997

Recent research in Australia and overseas has suggested that we are witnessing a convergence of men's and women's time on domestic labour activities. But there is disagreement about whether this is due to women reducing their time on housework or men increasing their time on housework. This article addresses these issues using national survey data collected in Australia in 1986, 1993 and 1997. The results show some changes in the proportional responsibilities of men and women in the home with men reporting a greater share of traditional indoor activities. But overall both men and women are spending less time on housework. In particular, women's time on housework has declined by six hours per week since 1986. Hence, while the gender gap between men's and women's involvement in the home is getting smaller, it is not the result of men increasing their share of the load, but is due to the large decline in women's time spent on domestic labour. There is also evidence of change in the relationship. between paid and unpaid work for women. Women's hours of,paid labour had a greater impact on their involvement in domestic labour in 1997 compared to a decade earlier. The article concludes that women's increased labour force involvement in combination with changing patterns and styles, of consumption is leading to some changes in the gender-division:of household labour, but not in the direction anticipated by earlier commentators on the domestic division of labour.

International Grassland Congress Outlook: An historical review and future expectations

Features of the history of the International Grassland Congress are mentioned. Aspects of a number of failed themes in grassland science are described with respect to molecular biology, intensive systems of ruminant production, carbohydrate use in plant growth, plant succession and range condition, and stocking method. Future expectations are focused on meeting a balance of objectives, maintaining reductionist science, taking new initiatives in plant improvement and in the development of animal production systems, and reducing barriers to international trade. The adoption of grassland science depends upon the growth of new learning, especially through cyclical interaction between scientists and farmers.

Dual mode cooling house in the warm humid tropics

Passive techniques as an alternative to artificial cooling can bring important energy, environmental, financial, operational and qualitative benefits. However, regions such as the wet tropics can reach high levels of thermal stress in which passive means alone are unable to provide appropriate thermal comfort standards for some parts of the year. Despite a great accumulation of empirical information on the passive performance of houses for either free-running or conditioned modes, very little work has been done on the thermal performance of buildings that can operate with a mixed-running strategy in warm-humid climates. Buildings with such design features are able to balance the needs for comfort, privacy, and energy efficiency during different periods of the year. As free-running and conditioned modes are believed by many to be 'opposite' approaches, and have been presented as separate strategies, this paper demonstrates that not all parameters are directly opposite and a possible dual-mode integrated operation can be used for warm-humid locations for maximum comfort and minimum energy requirements. For this purpose, simulation runs using ESP-R (University of Strathclyde, ESRU, UK) were based on the climate data of Darwin (Australia) and on the ventilation styles of the house: free running and conditioned. Design features applicable to both, i.e. for a dual mode operation could be identified and the differences between conditioned and free running were demonstrated and proved not to be totally conflicting and therefore suitable for a dual mode operation. Different daily usage profiles (five use patterns were defined), and zoning of sleeping and living areas are presented. The dual mode use patterns compared to the base case house, for all the user possibilities, had improved performances of 17-52%, when compared to the free-running mode and 66-98% when compared to the conditioned mode. Simulation runs using other warm-humid climates (Miami, USA; Sao Luis, Brazil; Kuala Lumpur, Malaysia) were also conducted and compared to the results found for Darwin. (C) 2002 Elsevier Science Ltd.

Selling Queensland at the Glasgow international exhibition of 1901

Queensland was one of two states of the newly-federated Australia to mount official courts at the Glasgow International Exhibition of 1901, the largest world expo held in Great Britain to that date. In exhibiting at Glasgow, then the second city of the British Empire, Queensland sought to draw emigrants and investment from Britain. The court, funded by the Queensland Department of Mines, was mostly a display of mineral wealth, and the state's agricultural and pastoral resources were poorly represented. The 'prettily designed' court presented a rose-coloured view of a land endowed with boundless wealth and resources. This in no way reflected the realities of life back home, in a year of environmental and economic disaster, and of political and social upheaval. Though the exhibit failed to bring tangible benefits, it is an important record of Queensland aspirations and concerns at the time of Federation. It has special interest as the last occasion when Queensland exhibited in its own right, rather than as part of the Commonwealth of Australia.

Nuclear weapons as obstacles to international security

This article argues that nuclear weapons serve no useful purpose in military calculations; moreover, their continued retention invites the dangers of further proliferation and of accidental use. They are thus defined here as obstacles to, rather than as facilitators of, international security. Seven reasons are presented to support this contention, including an assessment of the moral implications and the strategic limitations of nuclear weapons. Despite these limitations, and the recent commitments made by the nuclear weapon states to eliminate their arsenals, nuclear weapons remain central to the strategic doctrines of these states. Several reasons are put forward to explain why this retention continues, including the unchanging nature of strategic mindsets, the presence of vested interests, and now, in the case of the USA at least, a renewed reliance on nuclear weapons, regardless of how appropriate and effective such a strategy might be against emerging terrorist or `rogue state' threats.
