  • Description: Recent research indicates that an enhanced coarse gold problem may be present in some gold deposits. This can be due to the presence of gold particle clusters that give the effect of individual coarse-gold particles and leads to a high constitution heterogeneity (CH). These clusters, which may be distributed on the centimetre-scale or greater, give rise to high assay variability in field samples. However, once a sub-sample is pulverised, the effect of the clusters may be removed if the individual gold particles making up the clusters are liberated. Thus any resulting pulp will tend to have a low variability, unless true coarse-gold particles exist. Clusters are readily recognised in coarse gold deposits where they accentuate existing high nugget effect and CH. Clusters may however also occur in fine gold deposits where they produce an apparent coarse gold style. This is signaled by an unexpectedly high nugget effect from variography and poor correlation between field sample duplicates. The Gy sampling equation is applied to model coarse and fine gold deposits with clustered and non-clustered gold grains. Case studies illustrating observed effects of clustering are presented. If clustered particles exist, then proper protocol design at the field and early laboratory stage is paramount. The sample characterisation stage should include an assessment of possible gold article clustering, in addition to the standard descriptions of the gold particle size distribution. © 2007 Institute of Materials, Minerals and Mining and The AusIMM.

  • Description: Literature attests to the fact that psychosocial needs for cancer patients are not being adequately addressed. The tools, frameworks and guidelines developed, reflect differing professional perspectives and models of disease. Most studies have usually looked at what is happening from the patient and family's viewpoint in terms of medical and other needs. New national initiatives in psychosocial care include the organisation of nationwide practitioner workshops to encourage the implementation of the Clinical Practice Guidelines for the Psychosocial Care of Adults with Cancer. These guidelines focus mainly on the emotional and existential areas of need. The aim of this study was to: understand how a diversity of approaches and professional perspectives play out in everyday practice within a rural context; see how issues of distance and access affect this process; and highlight the deficiencies in the delivery of psychosocial services for cancer patients in rural Victoria. The study involved 59 questionnaire respondents (a 71% response rate), from which two interviews and six focus group discussions were drawn. Key findings were: regional and metropolitan hospitals and specialists not referring for support services; private patients missing out; general practitioners not referring to support services; late referrals to palliative care and district nursing; haphazard continuity of care for support needs of patients; and disputed responsibility for initial assessment.

  • Description: A study exploring older people's participation in their care in acute hospital settings reveals both consumers' and nurses' views of participation. Using a critical ethnographic design, data were collected through participant observation and interviews from consumers in acute care settings who were over 70 years old and nurses who were caring from them. Thematic analysis identified that older people equated participation with being independent. Importantly, consumers highlighted the complexity of the notion of participation when describing situations where they were unable to participate in their own care. The difficulties in communicating with health professionals and an inability to administer their own medications in inpatient settings were identified as barriers to participation. Understanding what consumers believe participation means provides a starting point for developing meaningful partnerships between health professionals and people receiving care.

  • Description: Purpose - The purpose of this paper is to extend the work of Carnegie and Walker and report the results of Part 2 of their study on household accounting in Australia during the period from the 1820s to the 1960s. Design/methodology/ approach - The study adopts a microhistorical approach involving a detailed examination of actual accounting practices in the Australian home based on 18 sets of surviving household records identified as exemplars and supplemented by other sources which permit their contextualisation and interpretation. Findings - The findings point to considerable variety in the accounting practices pursued by individuals and families. Household accounting in Australia was undertaken by both women and men of the middle and landed classes whose surviving household accounts were generally found to comprise one element of diverse and comprehensive personal record keeping systems. The findings indicate points of convergence and divergence in relation to the contemporary prescriptive literature and practice. Originality/value - The paper reflects on the implications of the findings for the notion of the household as a unit of consumption as opposed to production, gender differences in accounting practice and financial responsibility, the relationship between changes in the life course and the commencement and cessation of household accounting, and the relationship between domestic accounting practice and social class. © Emerald Group Publishing Limited.

  • Description: Purpose - Beyond the public world of work, the home provides an arena for examining accounting and gender in everyday life. This study aims to examine household accounting in Australia from the early nineteenth to around the mid-twentieth century. Design/methodology/approach - The study comprises two parts. The first part, as reported in this paper, presents evidence on household accounting as prescribed in the didactic literature in Australia, and evidence of actual accounting practices based on the examination of 76 sets of surviving Australian household records available in public repositories. The second part adopts a microhistorical approach involving the detailed scrutiny of 18 sets of accounting records and relevant biographical and family data on the household accountants involved. Findings - The study indicates that household accounting was an instrument for restraining female consumption, particularly during times of crises, and that accounting in Australian homes focussed on maintaining records of routine transactions as opposed to the preparation of budgets and financial statements. Household accounting in Australia was performed by women and men. The surviving records examined suggest that while areas of financial responsibility were defined by gender there was little evidence of formalised hierarchical accountability between spouses as has been found to be the case in Britain. Originality/value - The study extends knowledge of household accounting and gender. Most historical investigations on this subject draw on instructional literature. The current investigation also examines accounting practice in the home. © Emerald Group Publishing Limited.

  • Description: The purpose of this paper is to examine the role of company and executive characteristics in strategic alliance formation in the tourism sector of travel. A survey of Australian travel sector businesses was carried out and the results indicate a high level of interaction through alliances between various sectors of the Australian tourism industry. Top managers' characteristics (experience, ownership and risk-taking attitude) were found to be influential in taking strategic decisions of whether to form alliances or not. These characteristics do not play an important role in determining the number of alliances an organisation has and their geographical location, as much as company characteristics do. The findings of this paper imply that company characteristics are important in determining alliance formation. Managers should thoroughly consider these characteristics when deciding not only to form alliances, but also the types of alliances that could help their organisations to be more competitive, given limited resources.

  • Description: Purpose - This paper seeks to investigate the role of the university chancellor in the appointment of Australian vice-chancellors. Design/methodology/approach - Prior to this research it was evident that little research had been undertaken on the role of the chancellor. While the chancellor chairs Council, the incumbent also presides over quite a complex selection process, including chairing the selection Panel, when the need to appoint a new VC arises. Research into the recruitment and selection practices used to appoint vice-chancellors in Australia, undertaken as part of a PhD, yielded a wide range of useful material. The research also exposed some unexpected surprises, one of which was the role of the chancellor in the appointment process. Findings - The chancellor not only appeared to lead these processes, as would be expected, but was viewed as the key, if not sole, person who determined the successful candidate. It was found that the relationship between the chancellor and vice-chancellor was crucial and this was evident both in determining successful candidates and the decision for incumbents to seek a role elsewhere. However, in almost all cases the chancellor made the final decision when appointing a new VC. In some cases it appeared that selection panels considered their role as being simply to assist the chancellor to make a decision. This contrasted with the expectation that the panel as a whole would make a decision and recommend it to Council. Originality/value - Thus understanding the role of the chancellor is important when considering university governance and VC succession. This paper provides the findings of the research highlighting the significance of the chancellor's role in the context of appointing a new VC. © Emerald Group Publishing Limited.

  • Description: The main concern dealing with content-based image retrieval (CBIR) is to bridge the semantic gap. The high level query posed by the user and low level features extracted by the machine illustrates the problem of semantic gap. To solve the problem of semantic gap, this paper presents a hybrid technique using an emergence index and fuzzy logic for efficient retrieval of images based on the colour feature. Emergence index (EI) is proposed to understand the hidden meaning of the image. Fuzzy similarity measure is developed to calculate the similarity between the target image and the images in the database. The images were ranked based on their similarity along with the fuzzy similarity distance measure. The preliminary experiments conducted on small set of images and promising results were obtained.

  • Description: Objectives: To describe and compare the medium to long-term effectiveness of hydrodilatation and post-hydrodilatation physiotherapy in patients with primary and secondary glenohumeral joint contracture associated with rotator cuff pathology. Methods: Patients with primary and secondary glenohumeral contractures associated with rotator cuff pathology were recruited into a 2-year study. They all underwent hydrodilatation, followed by a structured physiotherapy programme. Patients were assessed at baseline, 3 days, 1 week, 3 months, 1 year and 2 years after hydrodilatation with primary outcome measures (Shoulder Pain and Disability Index, Shoulder Disability Index and percentage rating of “normal” function; SD%) and secondary outcome measures (range of shoulder abduction, external rotation and hand behind back). Comparisons in recovery were made between the primary and secondary glenohumeral contracture groups at all timeframes and for all outcome measures. Results: A total of 53 patients (23 with primary and 30 with secondary glenohumeral contractures) were recruited into the study. At the 2-year follow-up, 12 patients dropped out from the study. At baseline, the two contracture groups were similar with respect to their demographic and physical characteristics. The two groups of patients recovered in a similar fashion over the 2-year follow-up period. A significant improvement was observed in all outcomes measures over this period (p<0.01), so that both function and range of movement increased. The rate of improvement was dependent on the outcome measure that was used. Conclusions: Hydrodilatation and physiotherapy increase shoulder motion in individuals with primary and secondary glenohumeral joint contracture associated with rotator cuff pathology. This benefit continues to improve or is maintained in the long term, up to 2 years after hydrodilatation.

  • Description: To perform successfully in the workplace, employers demand that a new ICT graduate should be equipped with a strong set of technical skills, coupled with a flexible and creative approach to problem solving (Dawson, 2000; Hagan, 2004). To prepare students for their transition to industry, many tertiary institutions incorporate a team project into the final year of their IT and Computing courses (Clear, Young, Goldweber, Leidig, & Scott, 2001). Such projects include diverse technical areas including software development on specialised platforms, hardware design, networking problems and multimedia development. The importance of a software team project in final year computing degrees is without argument (Newman, Daniels, & Faulkner, 2003; Lynch, Goold, & Blain, 2004); however, there is academic debate about how to best achieve ‘industrial strength’ authenticity for students. Should the project problem be one constructed by academic staff? Or should the problem be that of a real client? In this paper we argue the latter case by describing our experiences drawn from supervising student ICT projects done for real clients in the local community across three different institutions. An assessment model for student projects that successfully promotes the development of good graduate attributes and the development of professional processes is detailed. The model includes explicit scaffolding and support structures to aid students engaged in real‐life (and loosely defined) software projects. We argue that assessment of project work is about valuing process as much as product; we also report upon lessons learned from implementing this model at different institutions.

  • Description: The Department of Primary Industries (DPI) is implementing a project – Sustainable Agribusiness Opportunities from the Wimmera Mallee Pipeline (SAOW) – funded through the Provincial Victoria Growth Fund, Regional Development Victoria (RDV) which aims to assist Wimmera Mallee farmers to maximise the opportunities that can be derived from this major change in water supply. As part of this project, the Water in Drylands Collaborative Research Program (WIDCORP) was commissioned by DPI to undertake research that provides insight into how farmers might react to such changes and what expectations they may have for their farming enterprises. This research informs DPI in developing a targeted and insightful approach to extension programs to assist farmers and farming groups connecting to the Wimmera Mallee Pipeline (WMP). The study involved an extensive literature review of socio-economic benefits of pipeline infrastructure and a multimode survey (telephone and online) of Wimmera Mallee farmers (n=527) to establish farmer typologies using farming style theory. Follow-up semi-structured interviews (n=16) were conducted with representative farmers from each of the defined ‘farming styles’. These interviews contextualised the characteristics of the styles, explored the implications for farm innovations and perceived opportunities, and identified key barriers and drivers influencing the uptake of innovation as a consequence of the WMP.

  • Description: This document presents a summary of the findings of a significant research project examining the implications of a more secure stock and domestic water supply system for a large dryland agricultural region. It identifies key issues, concerns and opportunities as perceived by farmers of various farmer typologies. It explores innovation, and the drivers and barriers to the adoption of new farming practices. The research was commissioned by the Department of Primary Industries (DPI) as part of the Sustainable Agribusiness Opportunities from the Wimmera Mallee Pipeline (SAOW) initiative. This research will inform DPI in developing a targeted and insightful approach to extension programs to assist farmers and farming groups connecting to the Wimmera Mallee Pipeline (WMP). More background information and detailed findings can be found in the full report located on the WIDCORP website (www.widcorp.com). The Wimmera Mallee Water Supply system historically delivered stock and domestic water across the dryland Wimmera Mallee region of Victoria via open earthen channels from storages in the Grampians to farms and town storages across the region (van Veldhuisen, 2001). Whilst this system was critical for the development of agriculture and communities within the region, wastage of approximately 103,000ML of water through evaporation and seepage across this system was no longer sustainable (GWMWater, 2003). In response to this situation, construction of the WMP Project commenced in late 2006, led by Grampians Wimmera Mallee Water (GWMWater) with funding from the community, state and federal governments. This major infrastructure project will replace the delivery of open channel water to the Wimmera Mallee farms and towns with a pipeline supply from headworks in the Grampians

  • Description: The on-line image retrieval process consists of a query example image, given by the user as an input, from which low-level image features are extracted. These image features are used to find images in the database which are most similar to the query image. A drawback, however, is that these low level image features are often too restricted to describe images on a conceptual or semantic level. The gap between the high level query from the user and low level features extracted by a computer is known as the semantic gap. Translating or converting the question posed by a human to the low level features seen by the computer illustrates the problem in bridging the semantic gap. This paper proposes a novel fuzzy approach for mapping the fuzzy database while extracting the colour features from image and assigning the weights to this fuzzy content when calculating the similarity between the query image and the images in database. Number of experiments was conducted on a small colour image database and promising results were obtained.
