A Taxonomy For Homework Used By Mental Health Case Managers When Working With Individuals Diagnosed With Severe Mental Illness, Peter Kelly, Frank P. Deane, Robert King, Nikolaos Kazantzis, Trevor P. Crowe Jul 2013

A Taxonomy For Homework Used By Mental Health Case Managers When Working With Individuals Diagnosed With Severe Mental Illness, Peter Kelly, Frank P. Deane, Robert King, Nikolaos Kazantzis, Trevor P. Crowe

Peter Kelly

A survey was completed by 122 case managers describing the types of homework assignments commonly used with individuals diagnosed with severe mental illness (SMI). Homework types were categorized using a 12-item homework description taxonomy and in relation to the 22 domains of the Camberwell Assessment of Need (CAN). Case managers predominately reported using behaviourally based homework tasks such as scheduling activities and the development of personal hygiene skills. Homework focused on CAN areas of need in relation to Company, Psychological Distress, Psychotic Symptoms and Daytime Activities. The applications of the taxonomy for both researchers and case managers are discussed.

A Review Of Consumer Involvement In Evaluations Of Case Management: Consistency With A Recovery Paradigm, Sarah L. Marshall, Trevor P. Crowe, Lindsay G. Oades, Frank F. Deane, David J. Kavanagh

Lindsay G Oades

This Open Forum examines research on case management that draws on consumer perspectives. It clarifies the extent of consumer involvement and whether evaluations were informed by recovery perspectives. Searches of three databases revealed 13 studies that sought to investigate consumer perspectives. Only one study asked consumers about experiences of recovery. Most evaluations did not adequately assess consumers' views, and active consumer participation in research was rare. Supporting an individual's recovery requires commitment to a recovery paradigm that incorporates traditional symptom reduction and improved functioning, with broader recovery principles, and a shift in focus from illness to well-being. It also requires …

Case Study In Academic And Industry Collaboration: The Development Of An Adolescent Targeted Sun Protection Intervention In Nsw, Melinda Williams, Sandra Jones, Donald Iverson, Peter Caputi, Sofia Potente

Don C. Iverson

Academic and industry collaboration is increasingly identified as a critical element in the future health of Australians through linking theory and practice, with the major priority for academic institutions being the identification of new knowledge and the transfer of this knowledge into changes in policy and health services. Collaborations between academia and industry are increasingly encouraged in Australia by research funding schemes such as ARCLinkage and, more recently, NHMRC Partnerships. While a recent US study suggests that such schemes have a moderate effect on academics’ propensity to work with industry (Bozeman and Gaughan, 2007), industry groups have recognised the value …

A Patient Experiencing Pseudoseizures: A Case Report, F Joseph, J Quinlan Jan 2012

A Patient Experiencing Pseudoseizures: A Case Report, F Joseph, J Quinlan

Faculty of Health and Behavioural Sciences - Papers (Archive)

Pseudoseizures are a relatively complex problem of unknown aetiology and prognosis. They can at times resemble genuine seizure attacks but they have no abnormal electroencephalograpic (EEG) activity. Understanding the patient's unique psychological background appears to be fundamental in managing seizure frequency. Pseudoseizures can be disruptive to a person's lifestyle, limiting their ability to function and progress in society, particularly when it comes to employment or social interaction. The case discussed involves a 59-year old man who presents with what is believed to be seizurerelated activity but through the course of clinical evaluation, this turned out to be pseudoseizures

When Does Alcohol Sponsorship Of Sport Become Sports Sponsorship Of Alcohol? A Case Study Of Developments In Sport In Australia, Sandra C. Jones Jan 2010

When Does Alcohol Sponsorship Of Sport Become Sports Sponsorship Of Alcohol? A Case Study Of Developments In Sport In Australia, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

Alcohol sponsorship of sport is common in Australia, with much debate about the appropriateness of linking sport with alcohol advertising and promotion. This paper provides examples of such sponsorships to appreciate the extent and nature of complex relationship between sport and alcohol sponsors. The public health and policy implications of alcohol sponsorship of sport extending to creating a sporting competition purely to promote an alcohol brand are considered.

A Multi-Scale Geospatial Study Of Wetlands Distribution And Agricultural Zones, And The Case Of India, N Nagabhatla, Rohan Wickramasuriya, N Prasad, Max Finlayson

Faculty of Science - Papers (Archive)

This paper highlights the global and the regional scale representation of wetlands ecosystems using geospatial tools and multiple data sets. At global scale, the Ramsar database is investigated for representation of the wetlands sites of international importance against the "global agricultural zones" derived from the thematic aggregation of Global Irrigated Area Map databases. The analysis of "Ramsar sites" under cultivation reflects the present trend in wetlands use for agriculture. The scenario is also compared with the historical pattern derived from Vavilov's food zones of 1926. Observed is an aggregate increase in cropped wetlands area from 25% (1926) to 43% (2006). …

An Alternative Approach To Coal Mine Site Water Management: A Case Study On West Cliff Colliery, Antony Volcich, Stephen A. Short, Adrian C. Hutton, Robert John Morrison Jan 2007

An Alternative Approach To Coal Mine Site Water Management: A Case Study On West Cliff Colliery, Antony Volcich, Stephen A. Short, Adrian C. Hutton, Robert John Morrison

Faculty of Science - Papers (Archive)

The provision of water supply, its usage and discharge, are major concerns for all mines, often accounting for a significant portion of the daily running costs. To reduce these costs, mines will collect as much site runoff as possible, and recycle the water whenever economically feasible. The constant recycling of on-site waters can mean that, over time, the levels of salinity, acidity or alkalinity, or other contaminants may build up within the internal water management system to a point which may lead to problems with licensed discharge requirements. This project investigated the water quality at West Cliff Colliery, in order …


Sampling Patchily Distributed Taxa: A Case Study Using Cost-Benefit Analyses For Sponges And Ascidians In Coastal Lakes Of New South Wales, Australia, P. B. Barnes, A. R. Davis, D. E. Roberts Jan 2006

Sampling Patchily Distributed Taxa: A Case Study Using Cost-Benefit Analyses For Sponges And Ascidians In Coastal Lakes Of New South Wales, Australia, P. B. Barnes, A. R. Davis, D. E. Roberts

Faculty of Science - Papers (Archive)

Estuaries worldwide are under increasing threat from human impacts. Because much of their fauna remains unstudied and in many cases undescribed, these systems present real challenges for effective management. In eastern Australia the study of estuarine fauna is often further complicated by its patchy distributions. This is particularly the case for assemblages of sessile invertebrates in coastal saline lakes. This study quantified distributions of sponges and ascidians at a hierarchy of spatial scales in the seagrass meadows of 2 coastal saline lakes in New South Wales, Australia. Nine species of sponge, many of which were undescribed, and 3 species of …


743 ± 17 Ma Granite Clast From Jurassic Conglomerate, Kamiaso, Mino Terrane, Japan: The Case For South China Craton Provenance (Korean Gyeonggi Block?), Allen Phillip Nutman, Y Sano, K Terada, H Hidaka Jan 2006

743 ± 17 Ma Granite Clast From Jurassic Conglomerate, Kamiaso, Mino Terrane, Japan: The Case For South China Craton Provenance (Korean Gyeonggi Block?), Allen Phillip Nutman, Y Sano, K Terada, H Hidaka

Faculty of Science - Papers (Archive)

The polymict Kamiaso Conglomerate (Mino Terrane, Japan) contains Jurassic to Palaeoproterozoic clasts—probably derived from Korean basement that lay nearby to the northwest at time of deposition. Clast K2 broke cleanly into two halves during sampling (but the halves were recombined for zircon separation). A third of the K2 zircons are colourless euhedral prisms with oscillatory zoning, with no inheritance and yielded a SHRIMP U/Pb date of 743±17 Ma. Two thirds of K2 zircons are brown oscillatory-zoned corroded prisms with a date of 1860±8 Ma, with inherited cores up to ∼2460 Ma. A likely explanation for this could be that clast …

An Automated Gis Method For Modeling Relative Wave Exposure Within Complex Reef-Island Systems: A Case Study Of The Great Barrier Reef, Marjetta L. Puotinen Jan 2005

An Automated Gis Method For Modeling Relative Wave Exposure Within Complex Reef-Island Systems: A Case Study Of The Great Barrier Reef, Marjetta L. Puotinen

Faculty of Science - Papers (Archive)

Patterns of wave energy play a significant role in shaping the long-term structure of coral reef communities worldwide. For example, sections of reefs have been shown to vary greatly in morphology (dominant size class, growth form) as coral colonies adapt in response to local-scale differences in the wave heights typically experienced. These differences result in zonation (crest, lagoon, and slope), producing characteristic growth forms and species assemblages that vary in their vulnerability to damage from waves (Done 1993). Those communities experiencing the greatest typical wave energy align themselves parallel to the water flow, adopt stream-lined forms and are usually smaller …


Evolution Of Chemical Contaminant And Toxicology Studies, Part 2- Case Studies Of Selenium And Arsenic, Glennys O'Brien, Dianne Jolley, Robert John Morrison Jan 2003

Evolution Of Chemical Contaminant And Toxicology Studies, Part 2- Case Studies Of Selenium And Arsenic, Glennys O'Brien, Dianne Jolley, Robert John Morrison

Faculty of Science - Papers (Archive)

As the second of a two part series discussing the evolution of the field of environmental toxicology, this paper presents two case studies: selenium and arsenic. Developments over several decades in the understanding of the behaviour of arsenic and selenium in different chemical forms in various compartments of the environment are discussed. Selenium was initially thought to be toxic, but later investigations showed it to be an essential micronutrient with a variety of biochemical functions, and, importantly, that there is a very narrow gap between the essential and the toxic body burden. Arsenic, on the other hand, has not yet …
