Sub-surface geology of the Kerang District, Murray Basin, Southeast Australia

The subsurface geology of the Kerang District was examined. The stratigraphic relationships between the Cenozoic western marine and eastern non-marine provinces of the Riverine Plain of the Murray Basin are now far better understood. A new three-fold subdivision of the Renmark Group, including the new Mystic Park Formation, is proposed.

Palaeontology, the biogeohistory of Victoria

The broad-scale distribution of fossils within Victoria is controlled by general global patterns in the biological evolution of life on Earth, the local development and environmental evolution of habitats, and the occurrence of geological processes conducive to the preservation of fossil floras and faunas. Early Palaeozoic fossils are mostly marine in origin because of the predominance of marine sedimentary rocks in Victoria and because life on land was not significant during most of this time interval. Middle Palaeozoic sequences have both terrestrial and marine fossil records. Within Victoria, marine rocks are only very minor components of strata deposited during the late Palaeozoic, so that few marine fossils are known from this time period. A similar situation existed during most of the Mesozoic except towards the end of this era when marine conditions began to prevail in the Bass Strait region. During long intervals in the Cainozoic, large areas of Victoria were flooded by shallow-marine seas, particularly in the southern basins of Bass Strait, as well as in the northwest of the State (Murray Basin). Cainozoic sediments contain an extraordinary range of animal and plant fossils. During the Quaternary, the landscape of Victoria became, and continues to be, dominated by continental environments including, at times, extensive freshwater lake systems. Fossil floras and faunas from sediments deposited in these lake systems and from other continental sediments, as well as from Quaternary sediments deposited in marginal marine environments, collectively record a history of rapid fluctuations in climate and sea level.

The ranking of factors influencing the behaviour of light structures on expansive soils in Victoria, Australia

In this paper a Neural Network Model was used to develop a ranking of the potential damage influences for light structures on expansive soils in Victoria. These influences include geology, Thornthwaite moisture index, vegetation covers, construction foundation type, construction wall type, geographical region and age of building when first inspected. Approximately 400 cases of damage to light structures in Victoria, Australia were considered in this study. Feedforward Backpropagation was adopted to train the data. The ranking of importance was estimated using connection weight approach and then compared to results calculated from sensitivity analysis. From the analysis, the ranking of importance for potential damage factor was noted.

An artificial intelligence examination of the influence of geological conditions and changes in climate on damage to light structures in Victoria

Damage to light structures in the state of Victoria can be caused by movements of expansive soils. The presentation will present the results of an examination of reports of increasing complaints of house damage in Victoria and particularly in the Melbourne area. The examination analyses the influence of geology and change in climate using Neural Network and Genetic Algorithm approaches and assesses their relative importance in contributing to the cause of the damage.

Urbanisation and the ecology of powerful owls ninox strenua in outer Melbourne, Victoria

Historically, the Powerful Owl (Ninox strenua) has been seen as a southeastern Australian species restricted to, or most numerous in, dense gullies of tall open forests in hilly or mountainous areas of the coast and Great Divide. However, recent research has revealed that Powerful Owls may breed numerously and successfully in a wider range of habitats than previously believed, including the forests and woodlands within the metropolitan areas of some major cities.Here we report on the breeding of a number of pairs of Powerful Owls in the Yarra Valley, Victoria. Study sites ranged from relatively undisturbed, wet sclerophyll forest 80 km from central Melbourne, through dry sclerophyll, eucalypt-dominated open forest with some disturbance, to a highly disturbed urban parkland only 18 km from central Melbourne. We found that Powerful Owls breed successfully in some urban areas, but are limited in the amount of human disturbance they can tolerate near their nesting hollow. In the most heavily utilized section of the urban parkland, all breeding attempts were unsuccessful and in one year the young were apparently eaten by one of the parents. This followed construction of a timber boardwalk under the nest tree during the breeding season. The Powerful Owls subsequently moved to a more secluded nesting hollow and raised two young. Recommendations for management of Powerful Owls in urban areas are discussed in the context
of these results.

Inspired by the past, driven by the passion: music in state-supported education in New South Wales and Victoria 1848-1920

This investigation considers the development of class music teaching in New South Wales and Victoria during the first seventy-two years of state-supported primary education. The first chapter describes the English background including music teaching methods (resulting from the mid-nineteenth century English choral singing movement) and the subsequent development of music teaching in English elementary schools. The promotion of school music is then considered on a broadly chronological basis in the two states and several themes are identified in relation to school music policy and practice. These include the status of music (core curriculum or extra-curricular subject), who should teach music (generalist or specialist teachers), what teaching methods and music notation should be used (staff or Tonic Sol-fa), musical training for generalist teachers, and curriculum content in relation to the aims and objectives of school music. Comparisons are made between developments in both states and between both states and English school music. The final chapter demonstrates the relevance of many of the historical themes identified for music education today. The thesis concludes by identifying a recurring problem from the past. namely the lack of co-ordination between various aspects of school music policy, as the most serious problem to be overcome in the future.

The dying town syndrome : a survey of urban development in the Western District of Victoria,1890-1930

The experience of urban settlement in the Western District of Victoria suggests that the pattern of growth and decline in small towns is tied to the pattern of land use. This, in turn, is determined by the economic and technological factors which influence farm management and practices. At times, these factors have encouraged urban development and small towns have flourished. For the most part, however, these forces have not been conducive to sustaining long-term growth and prosperity and small towns, have been trapped in a cycle of growth and decline.

The role and contribution of private land in Victoria to biodiversity conservation and the protected area system

The distribution and attributes of properties involved in three major programs for biodiversity protection on private land in Victoria, Australia, was investigated to determine their role in relation to the reserve system. Overlaying of dowsets in a geographic information system, with particular emphasis on property distribution in relation to bioregional and population centres, was undertaken. Land for Wildlife agreements had greater numbers of properties and total area protected in all bioregions throughout the State, yet average protected area sizes were lower than those of conservation covenants and Trust for Nature reserves. A combination of large bioregional area and human population size tended to attract more private conservation properties and, to a lesser extent, the total area they protected. The potential contribution that such properties made to biodiversity conservation varied between bioregions. Inclusion of properties within a national reserve framework is proposed to improve the coordination and effectiveness of conservation measures.

Legislation to protect whistle-blowers in Victoria

Protection afforded to whistleblowers under Victoria's Whistleblower Protection Act - benefits and costs of providing protection - types of disclosures that are protected and people who can claim protection under the Act - determining if a matter involves a public interest disclosure - investigation of disclosures by the Ombudsman, and other public bodies - action upon completion of an investigation - protection afforded to the Ombudsman.
