Three dimensional stability charts for slopes based on limit analysis methods

This paper uses finite element upper and lower bound limit analysis to produce chart solutions for three-dimensional (3D) natural slopes for both short- and long-term stability. The presented chart solutions are convenient tools that can be used for preliminary design purposes. The rigorous limit analysis results in this paper were found to bracket the true factor of safety within ±10% or better, which can be used as a benchmark for the solutions from other methods. The depth of the slip surfaces is observed to be generally shallow for most analyzed cases, particularly for the long-term slope stability problem. In addition, it was found that using a two-dimensional (2D) analysis may lead to significant differences in estimating safety factors, which can differ by 2%–60% depending on the slope geometry and soil properties. Therefore, great care and judgement are required when applying 2D analyses to 3D slope problems.

Slope stability charts for two-layered purely cohesive soils based on finite-element limit analysis methods

Stability charts for soil slopes, first produced in the first half of the twentieth century, continue to be used extensively as design tools, and draw the attention of many investigators. This paper uses finite-element upper and lower bound limit analysis to assess the short-term stability of slopes in which the slopematerial and subgrade foundation material have two distinctly different undrained strengths. The stability charts are proposed, and the exact theoretical solutions are bracketed to within 4.2% or better. In addition, results from the limit-equilibrium method (LEM) have been used for comparison. Differences of up to 20% were found between the numerical limit analysis and LEM solutions. It also shown that the LEM sometimes leads to errors, although it is widely used in practice for slope stability assessments.

Body fatness charts based on BMI and waist circumference

Objective To present percent body fat (PBF) charts based on body mass index (BMI) and waist circumference (WC) which can supplement current public health guidelines for obesity. Methods Based on data from the National Health and Nutrition Examination Survey (NHANES) III for 18- to 65-year-olds, a semi-parametric spline approach was utilized, in which no specific functional forms for BMI and WC are assumed, to depict graphically the relationship between BMI, WC, and PBF. Four distinct PBF charts were created, categorized by gender and ethnicity which are based on data from 2,170 white females, 1,902 African American females, 1,905 white males, and 1,635 African American males. Results PBF prediction based on the semi-parametric spline model outperformed competing linear models. For men, BMI is largely inconsequential, and WC plays a primary role in determining PBF levels. For women, the interaction between BMI and WC is more complex. To have low body fat, women would need to watch both their BMI and WC measurements carefully. Conclusions PBF charts, which incorporate information from three dimensions that are as simple to read as a BMI chart to help determine a person's level of fatness, were proposed.

Three-dimensional slope stability charts for frictional fill materials placed on purely cohesive clay

This paper investigates slope stability and produces a set of stability charts for three-dimensional (3D) slopes for a specific case in which frictional fill materials are placed on purely cohesive clay. As slopes are not usually plane strain in nature and are influenced by physical boundaries, this study uses a 3D analysis using the finite-element LB limit analysis method. Stability charts are convenient tools for geotechnical engineers during design in practice. For comparison purposes, the results from two-dimensional (2D) analyses are also discussed. The results from this study quantify the increase in the factors of safety obtained when 3D conditions are analyzed as opposed to the more traditional 2D.

Integrated natural resource management in Australia: the opportunity offered by a national coastal policy

Under the Australian Constitution the management (and planning) of Crown Land is a State and Territory Government responsibility. When this is considered in conjunction with the Offshore Constitutional Settlement, which affirmed that coastal waters out to three nautical miles (in general) offshore were also the responsibility of State and Territory Governments, then clearly coastal management in Australia is largely a State/Territory responsibility.

Beyond three nautical miles it is a different story. Under the United Nations Law of the Sea Convention (UNCLOS), which Australia ratified in October 1994, Australia claims jurisdiction out to 200 nautical miles and beyond (Wescott, 2000). These waters cover an area including the Antarctic claim of over 15 million square kilometres or twice the land area of Australia.

Hence in marine and coastal terms we have the national (Commonwealth) Government managing the oceans and seven State and Territory governments largely in charge of coastal management (coastal land and coastal waters). Heading "up river", State and Territory Governments plan and manage catchments.

Given the uncoordinated relationships between Australian coastal management policy and both catchment management policy and Australia's Ocean Policy (Commonwealth of Australia, 1998a and b), the Commonwealth Government's commitment to a "National Coastal Policy" presents an opportunity to progress the integration of natural resources management for the first time in decades.

From local to national: aspects of mapping the welfare third sector in Australia

The paper charts the authors' research experiences in various types of sociological mapping ofc ommunity or third sector organisations. Specifically this was a search for a way of understanding how third sector organisations dealing with welfare issues were operating in Australia in the mid I990s.

The paper tells the story of how the researchers worked through the implications of being faced initially with a dearth of information about their subject and of how lessons were learnt about the disjunctions between what is formally given as textbook knowledge about research practice and what actually can and does happen: that is, the relationship between the theory and the practice of research.

In discussing the creation of a database of organisations, conducting focus groups and a national sample survey, the paper comments on some of the practical problems facing third sector researchers as well as looking at concept generation and typology building as analytical tools.

Coastal state fisheries management : a review of Australian enforcement action in the Heard and McDonald Islands Australian Fishing Zone

In 1953 the Heard and McDonald Islands Act, which formalised the transfer of sovereignty over the two named sub-Antarctic islands from the United Kingdom, was passed by the Australian Government. For the ensuing 40 years, Australian management of the Islands was uneventful. The first subAntarctic scientific station was established at Atlas Cove, on Heard Island, in December 1947 following the initial indication by Britain of a willingness to transfer rights to the Islands. In 1987 the Islands, together with their 12 mile territorial sea, were proclaimed a wilderness reserve with a number of activities including fishing and mining prohibited. The same area was included on the WorId Heritage List in 1997. In 1979 a 200 nautical mile Australian Fishing Zone (AFZ) was proclaimed around all Australian territories. In 1994 new terminology was embraced and the Exclusive Economic Zone was declared.

Cancer patient preferences for communication of prognosis in the metastatic setting

PURPOSE: To identify preferences for and predictors of prognostic information among patients with incurable metastatic cancer. PATIENTS AND METHODS: One hundred twenty-six metastatic cancer patients seeing 30 oncologists at 12 outpatient clinics in New South Wales, Australia, participated in the study. Patients were diagnosed with incurable metastatic disease within 6 weeks to 6 months of recruitment. Patients completed a survey eliciting their preferences for prognostic information, including type, quantity, mode, and timing of presentation; anxiety and depression levels; and information and involvement preferences. RESULTS: More than 95% of patients wanted information about side effects, symptoms, and treatment options. The majority wanted to know longest survival time with treatment (85%), 5-year survival rates (80%), and average survival (81%). Words and numbers were preferred over pie charts or graphs. Fifty-nine percent (59%) wanted to discuss expected survival when first diagnosed with metastatic disease. Thirty-eight percent and 44% wanted to negotiate when expected survival and dying, respectively, were discussed. Patients with higher depression scores were more likely to want to know shortest time to live without treatment (P = .047) and average survival (P = .049). Lower depression levels were significantly associated with never wanting to discuss expected survival (P = .03). Patients with an expected survival of years were more likely to want to discuss life expectancy when first diagnosed with metastases (P = .02). CONCLUSION: Most metastatic cancer patients want detailed prognostic information but prefer to negotiate the extent, format, and timing of the information they receive from their oncologists.

Victorian marine habitat mapping project

Deakin University along with the CRC for Coastal Zone, Estuary and Waterway Management, the Glenelg Hopkins CMA and the Marine & Coastal Community Network have formed a partnership to map the benthic habitats at 14 sites across approximately 5% of Victorian State waters. The project is funded through the Federal Government by the Natural Heritage Trust and brings together expertise from universities, government agencies and private enterprise. We will be using hydro-acoustic sonar technologies, towed video camera and remotely operated vehicles to collect information on the types of substrate and bathymetry to derive habitat maps. The coastal fringe of Victoria encompasses rich and diverse ecosystems which support a range of human uses including commercial and recreational fisheries, whale watching, navigation, aquaculture and gas development. The Deakin lead initiative will map from the 10-metre contour (safe ship passage) to the three nautical mile mark for selected regions and will provide a geospatial framework for managing and gaining better understanding of the near-shore marine environment Research products will be used for management, educational and research purposes over the coming years.

In the realm of the hackers

In the late 1980s, Melbourne was the hub of the computer underground in Australia, if not the world. The hackers who formed the underground were not disgruntled computer professionals or gangs of organised criminals. They were disaffected teenagers who used their basic home computers to explore the embryonic Internet from inside their locked, suburban bedrooms. From this shadowy world emerged two elite hackers known as Electron and Phoenix, who formed part of an alliance called The Realm. In the Realm of the Hackers charts Electron's journey from his initial innocent explorations to his ultimate obsession. It vividly recreates the climate of the 1980s, before there was public access to the Internet. The program takes us headlong into the clandestine, risky but intoxicating world of the computer underground to uncover not only how the hackers did it but why.
