Fuels of the future : the challenge of new fuel types

Landscape disturbances associated with human activities result in many changes in vegetation structure and floristics. These changes include invasion of native vegetation by both introduced and native species, which leads to the development of 'new' vegetation types. These new vegetation types are often associated with greatly increased fuel loads, and increased levels of fire hazard. Two of these 'new' fuel types are dense thickets of woody weeds, such as Coyote Bush (Baccharis pilularis) and swards of exotic grasses with very high fuel loads, such as Buffel Grass (Cenchrus ciliaris) and Para Grass (Urochloa mutica). The 'new' fuel types which can now be recognized have significant implications for the accuracy of fire behaviour prediction and modelling. For example, modelling fire behaviour in areas invaded by exotic grasses in Australia is problematic, as current grassland fire behaviour models do not allow for the input ofthe high fuel loads associated with these invasive grasses. In forest, McArthur Forest Fire Danger Meters may not be appropriate for forests with significant levels of elevated fuels. Two case studies from southeastern Australia are discussed: the invasion of native vegetation in the urban interface by the woody shrub Burgan (Kunzea ericoides) and invasion of native grasslands by Phalaris (Phalaris aquatica).

Scenes from another life

What is my dance now? My body is saturated with images and details. My choreography has become an exorcism of ghosts of “opening-nights past” as I dance out memories and events inscribed on my body. A chorus of my other selves now accompanies my stage performance, live and virtual, real and imagined, past and present.

Intracellular zinc homeostasis in leukocyte subsets is regulated by different expression of zinc exporters ZnT-1 to ZnT-9

Intracellular zinc homeostasis is strictly regulated by zinc binding proteins and zinc transporters. In the present study, we quantified in a first global view the expression of all characterized human zinc exporters (hZnT-1-9) in different leukocyte subsets in response to zinc supplementation and depletion and analyzed their influence on alterations in the intracellular zinc concentration. We found that hZnT-1 is the most regulated zinc exporter. Furthermore, we discovered that hZnT-4 is localized in the plasma membrane similar to hZnT-1. hZnT-4 is most highly expressed in Molt-4, up-regulated after treatment with PHA and is responsible for the measured decrease of intracellular zinc content after high zinc exposure. In addition, we found that hZnT-5, hZnT-6, and hZnT-7 in Raji as well as hZnT-6 and hZnT-7 in THP-1 are up-regulated in response to cellular zinc depletion. Those zinc exporters are all localized in the Golgi network, and this type of regulation explains the observed zinc increase in both cell types after up-regulation of their expression during zinc deficiency and, subsequently, high zinc exposure. Furthermore, we detected, for the first time, the expression of hZnT-8 in peripheral blood lymphocytes, which varied strongly between individuals. While hZnT-2 was not detectable, hZnT-3 and hZnT-9 were expressed at low levels. Further on, the amount of expression was higher in primary cells than in cell lines. These data provide insight into the regulation of intracellular zinc homeostasis in cells of the immune system and may explain the variable effects of zinc deficiency on different leukocyte subsets.

Corporate governance, board responsibilities and financial performance : the National Bank of Australia

This paper examines board responsibilities and accountability by management and Board of Directors in relation to the National Australia Bank's (NABs) performance. The NAB, an international financial service provider within the top thirty most profitable banks in the world, is compared with the Australian major banks. The evidence suggests that NABs poor performance was consistent with a lack of accountability, poor corporate governance and board dysfunction associated with fraudulent currency trading and the subsequent AUD360 million foreign currency losses. The NAB's performance is investigated by utilising accounting-based measures of profitability and cost efficiency as proxies for performance. Following the foreign currency trading losses in 2004 the NAB under-performed the other major Australian banks in terms of profits, cost to income ratio and growth in assets. In terms of profitability and cost efficiency NAB had the lowest ROE and ROA with a 19.7% fall in net profit and the highest cost to income ratio of 5 7.4% of any of the five largest banks. This case study provides an Australian example of poor corporate governance and suggests that financial institutions and regulators can learn from the NAB's experience. Failure to have top-down accountability can have significant impact on over-all performance, profitability and reputation. In particular, it suggests that management and Boards need to review their risk management procedures and regulators need to be more pro-active in their prudential oversight of financial institutions.

Business to employee (B2E) e-business model : service to employees or organisational management?

This paper is a discussion of the B2E e-business model from the perspectives of employee services and organisational management. It includes literature to support B2E as employee services and organisational management with benefits to both. Intranets and portals are technologies supporting the implementation of the B2E e-business model which are also discussed. A case study is included to understand the application of the B2E model in a large organisation. Case study analysis indicates that the B2E e-business model is a service to the employees, however, these services are to support organisational efficiencies.

Knowledge management : the fundamental component for delivery

This paper seeks to examine the link between Knowledge Management (KM) and Quality Management (QM) with a particular focus on the role of a Quality Culture. The authors propose that as Knowledge Management reaches its maturity in terms of acceptance as an important part of doing business in the modern world, that quality will again become the mantra of successful companies. This time, however, quality will not only be defined in terms of the properties of the product and/or services that the organisation provides, but in a more holistic manner that is subject to rapid change and shifting customer preferences. This increasingly dynamic knowledge-driven environment will require companies to pay close adherence to quality in order to satisfy demand and stay ahead of the competition. A national survey of 1000 quality certified organisations in Australia was distributed with a 23% response rate. The survey asked questions pertaining to the organisations' use of Knowledge Management, their quality culture, as well as their quality performance measures. As a result of an analysis of the data, the authors suggest that, in order to survive in such a dynamic environment, organisations will have to embrace Knowledge Management as a fundamental component of delivery of a quality culture.

How well do women adapt to changes in their body size and shape across the course of pregnancy

This study examined body image across pregnancy. Pregnant women ( N = 158) completed measures of general attractiveness, feeling fat, fitness and strength, salience of weight and shape, and ideal and current body size at pre-pregnancy (retrospective), and in early, middle and late pregnancy. Body image was found to be fairly stable across pregnancy such that women who started with greater body concerns maintained them over time. Although women were least satisfied with their stomach size at late pregnancy, women's ideal body shape increased in parallel with increases in body size. Women with the most body concerns reported more depressive symptoms, tendency towards dieting, and smoking during pregnancy suggesting they were at greater risk in terms of health and well-being during pregnancy.

Knowledge management as perceived by quality practitioners

Purpose – This paper seeks to explore the relationship between knowledge management and quality management with a particular focus on the role of quality culture. The paper also aims to address the assumption that as knowledge management reaches its maturity, in terms of acceptance as an important part of doing business in the modern world, quality will again become the mantra of successful companies.

Design/methodology/approach – A total of 1,000 quality managers from Australian organisations were surveyed for their perspectives on current and future knowledge management and quality management approaches. The questionnaire utilised both quantitative and qualitative data collection methods. The questionnaire was broken into three sections: respondent profile, current knowledge management and quality management practices, and future predictions for both knowledge management and quality management.

Findings – The key finding of the paper was that organisations would have to embrace a quality culture as a fundamental component of implementing knowledge management in order to compete successfully in such a dynamic business environment. The responses from this survey assist in identifying the relationship between knowledge and quality management, and the importance and future of both knowledge and quality management.

Originality/value – This paper is based upon the assumption that quality is in fact, resurging. It has identified quality culture as the significant link between knowledge management and quality management that leads to successful competitive advantage. Organisations are urged to recognise knowledge management as a vehicle for success not a stand-alone process. It is the first time that such a survey has been designed, and the first time a paper has produced an explanation to the current situation.

The challenges for quality managers in Britain and Australia

Purpose – This paper aims to compare and contrast the career experiences and development needs of British and Australian quality managers.

Design/methodology/approach – The results of a postal survey of the careers of British quality managers are compared with Australian quality managers based on two surveys.

Findings – The study finds that quality managers in both countries brought wide functional experience to their roles. Their current jobs are major sources of intrinsic job satisfaction for both groups of managers but they utilise a very limited range of quality tools. Also British and Australian managers show little awareness in terms of their development needs for a broader background in quality.

Practical implications – The findings suggest a worrying lack of innovatory zeal amongst quality managers who appear to be more concerned with the maintenance of standards rather than taking a more dynamic approach. Thus it is argued that while quality managers bring wide functional experience to their current roles, there are many who do not appear to be at the cutting edge of knowledge in their field. Neither do the British quality managers in particular appear to be sufficiently aware of the need to address such shortfalls through professional development opportunities.

Originality/value – The roles of those charged with carrying the flag of quality in the two countries have only previously received limited research coverage. This paper, based upon empirical research in Britain and Australia, identifies issues which require the attention of senior management to ensure future competitiveness for their organisations.

Predictive mapping of powerful owl (Ninox strenua) breeding sites using Geographical Information Systems (GIS) in urban Melbourne, Australia

Urban expansion is a principal process threatening biodiversity globally. It is predicted that over half of the world's population will reside in urban centres by 2010. If we are to conserve biodiversity, a shift in perspective from traditional ecological studies based in natural environments, to studies based in less natural environments is paramount. To effectively conserve species which occur in urban environments, comprehensive analysis is necessary to determine the processes that are driving this urban usage. Geographical Information Systems (GIS) technology provides a valuable tool for efficient spatial analysis and predictive mapping of species distributions.

This study used GIS to analyze current breeding sites for the powerful owl, a vulnerable top order predator in urban Melbourne, Australia. GIS analysis suggests that a number of ecological attributes were influencing powerful owl usage of urban environments. Using these ecological attributes, predictive mapping was undertaken, which identified a number of potential breeding sites for powerful owls within urbanized Melbourne.

Urban environments are traditionally perceived as “the wastelands” of natural environments, however, this study demonstrates that they have the potential to support apex predators, an important finding for the management of rare and threatened species.
