The recent collapses of major Australian corporations and the human and economic consequences have emphasised the need for a new approach to auditing in Australia to fix the culture of complacency. The challenge is to continue to persuade directors, auditors and ASIC to better understand what the law requires, and to pressure government to create the conditions to ensure that ASIC undertakes appropriate enforcement.  相似文献

Construction kits have played a significant part in nurturing the growth and development of the minds and manipulation-based skills of children (and adults) in formal and non-formal education settings. These kits have origins rooted in the representation of the built world and now have a diversity of form and function, including technical versions with moving parts. This article examines some of the historically based ideas that lie behind the role that kits may have in terms of physical modelling. The article traces the transformation of kits from simple bricks and blocks into more complicated pieces for space-filling and achieving the transfer of forces and motion. This transformation occurred during the Victorian era when the influence of the ideas of educationalists and, perhaps rather strangely, exponents of early aviation, played major roles in determining the diversity of forms of construction kit and modelled possibilities that are now to be seen in classrooms and homes. The article ends with a review of some of the lessons from the past and present that will need to be considered in relation to concrete modelling in schools for the future.

In this second of two related papers in this issue, the causes of declining levels of housing transactions in Britain during the 1990s are explored. The lower transaction levels resulted partly from the changing behavior of young individuals. Both household formation and owner–occupation rates of these groups also fell sharply. Using panel data, we investigate the causes of reduced new household formation and owner–occupation, finding that changes in the income distribution away from young cohorts have been an important factor.  相似文献

In this article the impact of technology education, as a new learning area (subject) in the curriculum, on in-service teacher education in South Africa is described in order to ascertain the extent of the impact. The research on which this article is based draws on a variety of experiences and observations in the field at grassroots level (in particular an outreach project in rural communities). The envisaged impact of technology education on South African schools, communities, teacher educators and teachers, the range of in-service teacher education that is required, and the impacts in urban and rural areas are discussed. Finally a number of concluding remarks are made about the extent of the impact of the inclusion of technology education in the new National Curriculum Statement and whether the situation has changed since the implementation of a pilot technology education project in 1998. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献
