- Description: Rootkits refer to software that is used to hide the presence of malware from system/network administrators and permit an attacker to take control of a computer. In our previous work, we designed a system that would categorize rootkits based on the hooks that had been created. Focusing on rootkits that use inline function hooking techniques, we showed that our system could successfully categorize a sample of rootkits using unsupervised EM clustering. In this paper, we extend our previous work by outlining a new procedure to help system/network administrators identify the rootkits that have infected their machines. Using a logistic regression model for profiling families of rootkits, we were able to identify at least one of the rootkits that had infected each of the systems that we tested. © 2010 IEEE.

This paper reports the findings of a qualitative grounded theory study of 70 such practitioners living and working in rural Victoria. Australia, with regard to the development of worker expertise in dealing with personal and professional role boundary issues. The research findings suggested that this group of rural health and welfare practitioners dealt with personal and professional boundary issues through a process of sensitive decision-making and strategic behaviour that became increasingly intuitive over time. Participants oftern adopted elastic and fluid boundaries using their personal experience and local knowledge to inform their professional judgement. These findings have implications for practitioners, for employers, and for educators.

- Description: Objective: To determine the factors that influence appropriate restraint usage by child occupants across the age range for which any type of child restraint may be appropriate (0-10 years). Design: Randomized household telephone survey. Setting: Statewide survey, New South Wales, Australia. Subjects: Parents or carers of children aged 0-10 years. Main outcome measures: Parental reporting of appropriateness of child restraint. Methods: Demographic information and data on age, size, restraint practices, parental knowledge of child occupant safety, and attitude to restraint use was collected using a structured interview. Data were analysed using logistic regression after cluster adjustment. Results: Inappropriate restraint use by children was widespread, particularly in children aged 2+ years. Overall, parental knowledge of appropriate ages for restraint transitions was associated with increased likelihood of appropriate restraint use. Lower levels of formal parental education, larger families, parental restraint non-use, and parent/child negotiability of restraint use were predictors of inappropriate restraint use. For particular child age subgroups, the parental knowledge that predicted appropriate restraint use was specific to that age group. Most parents felt that they knew enough to safely restrain their child, despite widespread inappropriate restraint use. Conclusions: Parents are more likely to make appropriate restraint choices for their children if they possess restraint knowledge specific to their children's age and size. Educational campaigns may be most effective when they provide information for specific ages and transition points. Strategies to overcome parents' misplaced confidence that they know enough to restrain their children safely are also indicated.

- Description: Informal learning has often been seen as formal learning's 'poor cousin'. Our paper explores and discusses new and different ways of thinking about defining, valuing and researching the breadth and importance of informal learning in diverse national and cultural contexts. This includes a consideration of the power relations that can act to devalue informal learning. It is underpinned by a recognition that not only do a relatively small proportion of adults currently engage informal learning, but those who do tend already to be dedicated and successful lifelong learners. It leads to a discussion about how informal learning might be framed as part of the solution to adult exclusion, seen to be aggravated by unnecessary adult educational hierarchies, accreditation, assessment and formality.

- Description: Objectives: The purpose of this study was to investigate whether melatonin levels in older cohorts within the 'aged' population were significantly lower than in younger 'aged' individuals and hence point to a possible confound in cross-sectional studies which group individuals over 55 in one category. Setting and design: Melatonin levels of 35 North Queensland residents over 55 years of age living in an aged-care facility, a retirement village or the general community were compared across three age groups. Methods: Subjects were ten 56-65 year olds, eighteen 66-75 year olds and seven over-75 year olds. Information was obtained on sleep, awakening, medical conditions and medications, with subsequent exclusion of those with known medical conditions and/or medications. Melatonin was collected by salivary samples at 2200 hours and concentrations were determined by immunoassay. Results: Mean melatonin levels were significantly lower (p=.03) in the 'oldest' (over 75 yrs) group compared to the 'youngest' (56-65 yrs) group. Main findings: The results of this preliminary study indicate that within the older population, melatonin levels appear to decline significantly with age. Conclusions: Future studies of melatonin and ageing may benefit from a longitudinal approach, with older subjects sampled across time. Copyright © Neuroendocrinology Letters.

- Description: The objective of this project was to investigate the potential of electrokinetic treatment techniques to stabilise volume change characteristics of expansive soils. The investigations were carried out in the laboratory using locally collected expansive soils from three locations in central Victoria, Australia. A layer of soil was placed in glass tanks (900 mm x 350mm plan area) and compacted to a known density and water content typical of field conditions. Using electrodes inserted into the soil, a direct current was passed across the soil under different voltage gradients of 0.5, 1.0 and 2.0 V/cm for periods of 3, 5, 7, 10 and 14 days. After electrokinetic processing, soil were tested for volume change properties using soil reactivity indicators such as consistency limits, linear shrinkage, free swell index and shrink-swell index. The test results show that with electrokinetic treatments, the volume change potentials of the experimental soils reduced to a greater or lesser degree depending on the magnitude of the voltage gradient and processing time. Under certain voltage gradients and treatment durations, some experimental soils transformed from extremely reactive status to a slightly or almost non-reactive status. The experimental results suggest the potential of developing electrokinetic treatment technique to stabilise volume change properties of expansive soils effectively and efficiently.

- Description: Purpose - This paper aims to replace the complicated iterative procedure used to prevent interference in limacon-to-limacon machines by a simplified mathematical equation which can be solved by a straightforward substitution of the required clearance value. Design/methodology/approach - The input data to the iterative procedure and the obtained results have been employed in regression models to construct the sought after equation. Searching for a proper form of this equation involved numerical experiments to study the effects of the various model parameters on the system response. Findings - The numerical experiments conducted proved to be an effective model construction technique, and the regression model proposed has been found extremely accurate in the specified parameter space. Research limitations/implications - The proposed equation is applicable within the parameter range chosen for the study. This range is the one often used for industrial applications. Should the parameters selected for a specific design fall outside the specified range, the proposed model structure may have to be varied to maintain a desirable level of accuracy. Practical implications - The interference study is a part of the iterative procedure employed to design the dimensions of the limaçon-to-limaçon machine. This iterative procedure searches for the proper design amongst hundreds of various possible solutions. The results of this paper will ensure a much faster convergence for the design procedure, since the interference study will be eliminated from the iterative section of the analysis. Originality/value - The paper offers a valid and accurate model that can be efficiently used for the intended purpose. © Emerald Group Publishing Limited.

- Description: Improvements of vehicle fuel economy are being considered using a mechanically driven flywheel to reduce the amount of mechanical energy produced by the thermal engine recovering the vehicle kinetic energy during braking. A mechanical system having an overall efficiency over a full regenerative cycle of about 70%, about twice the efficiency of battery-based hybrids, is coupled to a naturally aspirated gasoline engine powering a full size sedan. Results of chassis dynamometer experiments and engine and vehicle simulations are used to evaluate the fuel benefits introducing a kinetic energy recovery system and downsizing of the engine. Preliminary results running the new European driving cycle (NEDC) show KERS may reduce fuel consumption by 25% without downsizing, and 33% with downsizing of the 4 litre engine to 3.3 litres.

(Re)creating spaces within rural general practice : Women as agents of change at the organisational and practitioner levels

- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis examines how women, as agents of change, contest the male-dominated structures at the organisational and practitioner levels of rural medicine in Australia. The premises for this study are that females now outnumber males as medical graduates and general practice trainees, yet women are significantly less likely than men to occupy rural and remote practice positions in Australia. Furthermore, the organisation of medicine remains strongly patriarchal. A feminist qualitative design underpins this empirical study involving: in-depth interviews with seventeen women activists and thirteen rural women general practitioners; grounded theory analysis of transcribed interviews; and interpretation of findings through a feminist poststructural lens. Findings uncover the gendered organisational and practitioner environment through which change is negotiated. At the organisational level, male exclusionary practices – played out through the ‘male as norm’ and the ‘problem is women’ discourses – position women in highly contradictory ways and marginalise their voices. Yet simultaneously, activists are challenging entrenched interests through individual and collective strategies of change which include: initiating gender-awareness projects; claiming legitimacy by using male-centred tactics and women-defined discourses; developing female-friendly initiatives; and mentoring of and building alliances between women. At the practitioner level, results reveal how women’s everyday lives as rural general practitioners are shaped by oppositional tensions. However, beyond the struggle of ‘fitting in’, women are altering rural medicine by (re)shaping meanings and (re)constructing work practices. Furthermore, their narratives suggest that rural spaces are integral to ways women carve out women-defined practice. A key innovation of this thesis is analysis of change at dual levels, both organisational and practitioner. This thesis marks a significant advancement upon the usual themes that attend only to the marginalisation of women and rural areas. It highlights the transformative process through which women (re)create the discursive spaces of rural general practice.

- Description: The field of constrained non-linear optimization is one of the most practically applicable areas of mathematics. It has been used successfully to solve problems in a wide range of areas including economics, communications and computational chemistry. In recent years some problem reformulation techniques have been suggested for dealing with non-convex problems. However most of this study has been of a theoretical nature and very little is known about its effect on the practical impact of these techniques. In this seminar we will outline some of the reformulation techniques which have been suggested and present numerical results which show their relative efficiencies in solving some test problems.

- Description: The field of constrained non-linear optimization is one of the most practically applicable areas of mathematics. It has been used successfully to solve problems in a wide range of areas including economics, communications and computational chemistry. In recent years some problem reformulation techniques have been suggested for dealing with non-convex problems. However most of this study has been of a theoretical nature and very little is known about its effect on the practical impact of these techniques. In this seminar we will outline some of the reformulation techniques which have been suggested and present numerical results which show their relative efficiencies in solving some test problems. We will ultimately suggest that a reformulation scheme which combines a logarithmic reformulation of the objective function and an exponential reformulation of the constraint function provides many desirable outcomes.

- Description: The literature has identified some potential problems and challenges associated with teenage part-time workers and the nature of the workplaces that employ them. However a large national project on student-working found few problems in the two companies researched because these companies had policies in place that addressed the potential problems. Some suggestions are made about how problems and challenges could be avoided in a wider range of adolescent workplaces.

- Description: The Beautiful Firetail (Stagonopleura bella) is an uncommon, granivorous finch from coastal south-eastern Australia, with a distribution extending from mid-coastal New South Wales to south-eastern South Australia, including Tasmania. This paper presents a quantitative assessment of habitat use by the Beautiful Firetail based on data collected from 30 paired riparian and non-riparian sites in the foothill forests of the Victorian Highlands, Australia. The Beautiful Firetail occurred in two of the three forest blocks surveyed and was found almost exclusively at riparian sites. The Beautiful Firetail was most likely to occur at riparian sites on the coastal fall of the ranges at sites with high sedge cover and low cover of shrubs and bare ground. The species occurred at low densities (0.10-0.19 individuals ha-1) throughout the year. Records from the Atlas of Victorian Wildlife were used to describe the distribution of Beautiful Firetails in Victoria. Notable observations inland of the Great Dividing Range were recorded during the present study. Further study is required to understand the ecological requirements of the Beautiful Firetail throughout its range. © Royal Australasian Ornithologists Union 2005.

- Description: This short report describes a 20-month follow-up of safe diving skills, extending the 8-month retention period previously published in this journal. Thirty-four recreational swimmers with poor diving skills were evaluated before and immediately after a diving skills intervention program. Twenty-two returned for the eight-month follow-up evaluation and 16 returned 20 months post. As with the earlier study, Treadwater, Deck, Block and Running dives were video-recorded, and maximum depth, distance, velocity, entry angle and flight distance were compared. Underwater hand and arm positions were examined. Pre-intervention, a breaststroke arm action before maximum depth occurred in 18% of all dives and 38% of Treadwater dives. This was eliminated post-intervention, improving head protection. The Treadwater dive elicited the greatest mean maximum depth, and ANOVA showed depth for this entry decreased (improved) following intervention and remained shallower at the eight-month and 20-month post follow-ups. The Block dive also became shallower following intervention while the Deck dive remained unchanged. As seven 10-minute skills sessions resulted in shallower dives with safer hand and arm positions, and these skills were retained over a 600 day non-practice period, it is reliable to consider that the inclusion of safe diving skills in learn-to-swim programs can provide a diving spinal cord injury prevention strategy.

- Description: OBJECTIVE - The purpose of this study was to assess the effectiveness of a low-resource-intensive lifestyle modification program incorporating resistance training and to compare a gymnasium-based with a home-based resistance training program on diabetes diagnosis sa us and risk. RESEARCH DESIGN AND METHODS - A quasi-experimental two-group study was undertaken with 122 participants with diabetes risk factors; 36.9% had impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) at baseline. The intervention included a 6-week group self-management education program, a gymnasium-based or home-based 12-week resistance training program, and a 34-week maintenance program. Fasting plasma glucose (FPG) and 2-h plasma glucose, blood lipids, blood pressure, body composition, physical activity, and diet were assessed at baseline and week 52. RESULTS - Mean 2-h plasma glucose and FPG fell by 0.34 mmol/l (95% CI -0.60 to -0.08) and 0.15 mmol/l (-0.23 to -0.07), respectively. The proportion of participants with IFG or IGT decreased from 36.9 to 23.0% (P = 0.006). Mean weight loss was 4.07 kg (-4.99 to -3.15). The only significant difference between resistance training groups was a greater reduction in systolic blood pressure for the gymnasium-based group (P = 0.008). CONCLUSIONS - This intervention significantly improved diabetes diagnostic status and reduced diabetes risk to a degree comparable to that of other low-resource-intensive lifestyle modification programs and more intensive interventions applied to individuals with IGT. The effects of home-based and gymnasium-based resistance training did not differ significantly.

- Description: A teacher professional development program using applied behavioural techniques was delivered to primary school teachers. Teachers (N=78) rated the program highly and reported improved knowledge and skills in managing disruptive student behaviour. Objective measures of teacher (n=32) pre- and post-workshop data revealed significant changes in teachers' use of positive strategies for female students. Change in teachers' use of punishment was in the expected direction, with insufficient power to produce statistical significance. Juxtaposed to high teacher self-reported satisfaction are objective pre and post data for a small group of very difficult students who showed no change in disruptive behaviour. This study found that teacher satisfaction ratings are a poor indicator of change in the classroom and argues that professional development for teachers must incorporate objective measures of child behaviour.

The findings demonstrates that although businesses are, to a different degree, aware of the concept of CSR and that they have a positive attitude to engage in CSR with an intention to contribute to addressing wider social and community needs; the CSR practices are seldom integrated into business strategies. The findings of the paper have some important implications for businesses and organizations working to promote CSR among businesses in developing countries.

- Description: Despite a rise of interest in information communications technology (ICT) and in community informatics (CI) initiatives, these are not ‘magic bullets’ or ‘quickfix solutions’ for SMEs or even larger organisations, communities, or industries. There is growing recognition of the need to go beyond anecdotal evidence and to assess more effectively the change brought about by providing access to and utilisation of ICT in communities. Denison et al. (2002) have presented a taxonomy that differentiates between various types of ICT and community networking initiatives. The application of this schema to a cluster of community informatics initiatives originating from the Central Highlands region of Victoria proves to be useful. A single case study is then presented which reviews the evolution of GrowExport.com, one of the online communities within that cluster. The diverse factors that are involved in establishing sustainable online services are examined. Access to a comprehensive toolset specifically designed to meet the skills and infrastructure gaps that often exist in regional areas has been important. The active involvement of community members in designing, implementing and sustaining web-based services has also been important. By generating debate and discussion and by sharing the critical learning from specific cases it is hoped that others can be better informed about the major characteristics and the diverse factors which impact on the effectiveness and long-term sustainability of CI initiatives in a regional and rural context.

Exception? What exception? Foucault’s state of convention

- Full Text:
- Description: The notion of the ‘state of exception’ (i.e. the sovereign decision to suspend some or all of the suite of rights, freedoms and obligations associated with the social contract) understands that such rights and obligations normally exist and function as protections. Giorgio Agamben’s work figures the contract suite’s institutionalised presence in terms of this conceptualisation, and then contemplates a permanent state of exception. However, in Foucault’s work on ‘governmentality’, the contract suite functions as a conceptual veneer, in the service of the state’s self-preservation rather than as protection for citizens. This perspective has implications for the usefulness of the notion of the exception as a way of understanding modern political obligation and authority. It is in this context that antifoundationalist synergies between Foucault, Hume and others will be considered, particularly with regard to the role of convention in a governmentalist understanding of the relation between citizens and the state.
