Molecular interactions behind the synergistic effect in mixed monolayers of 1-octadecanol and ethylene glycol monooctadecyl ether

Mixed monolayers of 1-octadecanol (C18OH) and ethylene glycol monooctadecyl ether (C18E1) were studied to assess their evaporation suppressing performance. An unexpected increase in performance and stability was found around the 0.5:0.5 bicomponent mixture and has been ascribed to a synergistic effect of the monolayers. Molecular dynamics simulations have attributed this to an additional hydrogen bonding interaction between the monolayer and water, due to the exposed ether oxygen of C18E1 in the mixed system compared to the same ether oxygen in the pure C18E1 system. This interaction is maximized around the 0.5:0.5 ratio due to the particular interfacial geometry associated with this mixture.

The Movement between: Dance improvisation, witnessing and participatory performance.

This was a practice-based project which extended the possibilities for dance improvisation in performance. The project engaged questions about how live performance is constituted, about what the roles of the dancer and audience might entail, and about how a community of common experience can develop through a responsive exchange between its participants.

Moving beyond mateship:reconstructing Australian men's practices

In this chapter I will explore the implications of the definitively Australian
style of masculine behaviour called 'mateship' for gender relations in
Australia. Mateship is part of the Australian male heritage; it originated in
colonial days and was glorified in war and sport. The feminist movement
in Australia has challenged the dominant form of masculinity inherent in
mateship and the basic rationale for gender relations that flow from it. In
this context, I will discuss Australian profeminist men's attempts to challenge patriarchal gender relations and construct non-patriarchal subjectivities and practices. Theorizing about masculinity in Australia has tended to be derivative of overseas literature. This is partly because publishers are looking for overseas markets for their books so they discourage writers on masculinity from grounding men's practices in a specifically Australian context. While there are benefits in generalizing about western masculinities, such writing misses the uniqueness of the lived experiences of Australian men. It is this uniqueness that I will address in this chapter. As McGrane and Patience (1995: 15) note, 'Australian masculinism has a history of its own that needs to be recognized at the same time as it can be usefully compared to the masculinisms of similar cultures'.

Re-gendering labour: class and gender determinants of New South Wales electoral behaviour 1930-32

Historians have neglected tbe impact of female enfranchisement on Australian electoral outcomes. This papers employs multivariate analysis to explore electoral behaviour in New South Wales during the Great Depression. It argues that women were less prone to support Labor than men, but that women in paid employment constituted a partial exception to this pattern. In 1932 the conservative parties significantly eroded Labor's working-class support. Part of this success was due to the ability of employers to coerce workers with the threat of dismissal. Female wage earners were particularly vulnerable to this coercion. Conservative electoral appeals recast masculinity in terms of family responsibility rather than class assertion. Conflict in the household economy possibly influenced women to vote against Labor due to its identification with the cause of male breadwinners. Overall female voting behaviour was more stable than that of men and this despite the higb profile of issues that would have been expected particularly to influence female voters.

From "try it and see" to strategic exploration: characterizing young children's scientific reasoning

This article explores ways of characterizing different dimensions and levels of scientific reasoning in early elementary school children, in the context of open explorations. The article focuses on children's performance on three probes which involve using evidence to generate and evaluate knowledge claims. A number of dimensions have been used to characterize children's approaches to exploration and knowledge construction, which demonstrate the interrelationship between conceptual knowledge and scientific reasoning. Children differed markedly across these dimensions, yet individual children were relatively consistent in their approach to the tasks. The major differences in performance are linked to fundamental distinctions in the way ideas are viewed in relation to evidence.

Parallelization of the discrete gradient method of non-smooth optimization and its applications

We investigate parallelization and performance of the discrete gradient method of nonsmooth optimization. This derivative free method is shown to be an effective optimization tool, able to skip many shallow local minima of nonconvex nondifferentiable objective functions. Although this is a sequential iterative method, we were able to parallelize critical steps of the algorithm, and this lead to a significant improvement in performance on multiprocessor computer clusters. We applied this method to a difficult polyatomic clusters problem in computational chemistry, and found this method to outperform other algorithms.

Sensor fusion based missile guidance

In this paper we improve the guidance system performance via sensor fusion techniques. Vision based guidance systems can be improved in performance via radar tacking or employing video tracking by unmanned jying vehicles. We also introduce an image texture gradient based image segmentation technique to identify the target in a typical surface-to-air type application with the proposed Robust Extended Kalman Filter based state estimation technique for the implementation of the Proportional Navigation guidance controlleller.

Protecting information systems from DDoS attack using multicore methodology

Previous work, in the area of defense systems has focused on developing a firewall like structure, in order to protect applications from attacks. The major drawback for implementing security in general, is that it affects the performance of the application they are trying to protect. In fact, most developers avoid implementing security at all. With the coming of new multicore systems, we might at last be able to minimize the performance issues that security places on applications. In our bodyguard framework we propose a new kind of defense that acts alongside, not in front, of applications. This means that performance issues that effect system applications are kept to a minimum, but at the same time still provide high grade security. Our experimental results demonstrate that a ten to fifteen percent speedup in performance is possible, with the potential of greater speedup.

Untitled. Conundrum, September 2004

Conundrum is about improvisation as a performance practice. Conundrum is a hybrid event with dancers, actors, and musicians participating in a format that is informal, maintains modest production values and is rooted in the performers desire to practice improvisation in performance. Conundrum is the defining event, a lighthouse to pinpoint and illuminate a range of improvisation and body practices which constellate around the space known as Cecil Street Studio located in Fitzroy, Melbourne.

Occupational health and safety management systems : system types and effectiveness

The aim of this thesis is to develop a framework to evaluate the relative performance of different types of health and safety management system. This objective is an analytical one, but it stems from a policy issue of public importance. Over the past decade Australia, like other countries, has seen the emergence and growth of interest in developing health and safety management systems. But are they all the same, and if not, do they differ in their effectiveness? The thesis does not seek to give a definitive answer to these questions. Given the novelty of the phenomenon and the lack of research on this subject, the research is exploratory. An hypothesis about the effectiveness of different health and safety management systems is developed rather than tested. The thesis proceeds by first defining health and safety management systems as a combination of the planning and review, the management arrangements, the consultative arrangements and the specific program elements that work together in an integrated way to improve health and safety performance. A research procedure is described involving twenty exploratory case studies. The thesis then - develops - from the literature and the case study research - an analytical framework to evaluate the performance of different health and safety management systems. That framework has two parts. First is a typology of health and safety management systems. This is constructed from two distinctions - between 'safe place' and 'safe person' approaches to health and safety; and between 'innovative' and traditional' management methods and structures. These distinctions yield four types of system. The typology was applied to the case studies which yielded a reasonable fit in most instances. The second part of the framework is a 'process evaluation' technique akin to Quality standards. Derived from the Victorian SafetyMAP audit criteria, the "e;process evaluation tool "e; is preferred to traditional outcome measures such as incident or claim rates. Using this measure, the twenty case study enterprises were classified as above average, average or below average in performance. These results correlated poorly with traditional incident trend and benchmark measures. The two elements of the framework are then combined to explore the relationship between the different types of system and their performance. Evidence from the twenty case studies showed a tendency for innovative/safe place firms to perform better than traditional/safe person firms. This finding can form the basis for a hypothesis that may be subject to statistical testing on a generalisable sample. In addition five 'best practice' cases were selected and subjected to a cross case analysis to search for common characteristics that might explain their performance. This analysis suggests the importance of a number of factors: senior managers who drive health and safety change and mobilise all possible resources in the pursuit of change; health and safety representatives who work with managers in a 'joint regulatory relationship' across system activities; the involvement of employees more generally, but not as a substitute for action by managers and health and safety representatives; a comprehensive approach to elimination of all hazards; and the introduction of innovative programs to continually improve systems and facilitate employee involvement in health and safety.

Women as consumers of a male domain : Australian Rules Football and its female fans

Looked at from a global perspective, sports are mostly male preserves. Those played by women seldom attract a large spectatorship and the numerous at-ground viewers of men’s play mostly are men. An exception is Australian Rules Football (AFL), a male sport that since the 19th century has drawn a considerable female following, with women accounting for about half of the ‘live’ crowds. From single-person and focus group interviews conducted with female AFL fans, we examine how women voice their support for a sport characterised by hyper-masculinity in players’ on-field and off-field behaviours, in the organisation and control of the sport, and in the ‘natural’ authority credited to men’s voices in commentary and interpretation of it. Given their marginalisation in AFL and in sports generally, what do women fans gain from their avid support of AFL and how does this influence the construction of their identities as women? We examine these issues from a perspective supporting the idea of multiple, fragmented identities.

High rates of oxygen reduction over a vapor phase-polymerized PEDOT electrode

The air electrode, which reduces oxygen (O₂), is a critical component in energy generation and storage applications such as fuel cells and metal/air batteries. The highest current densities are achieved with platinum (Pt), but in addition to its cost and scarcity, Pt particles in composite electrodes tend to be inactivated by contact with carbon monoxide (CO) or by agglomeration. We describe an air electrode based on a porous material coated with poly(3,4-ethylenedioxythiophene) (PEDOT), which acts as an O₂ reduction catalyst. Continuous operation for 1500 hours was demonstrated without material degradation or deterioration in performance. O₂ conversion rates were comparable with those of Pt-catalyzed electrodes of the same geometry, and the electrode was not sensitive to CO. Operation was demonstrated as an air electrode and as a dissolved O₂ electrode in aqueous solution.

The PTT-20 : UK normative data for 5-11 year olds on a 20 item past tnese taskThe PTT-20: UK normative data for 5- to 11-year-olds on a 20-item past-tense task

Background: Grammatical morphology, particularly the use of the past tense in English, has been identified as a behavioural marker for specific language impairment. However, there is a dearth of instruments that assess key verb features, are short and easy to administer for clinical use, and have normative data for the UK population.

Aims: The present study aimed to develop a short version of a past-tense task (named the PTT-20) and to provide UK normative data for a large control sample of primary school-age children.

Methods & Procedures: The task consisted of 20 items taken from a well-known 52-item task developed by Marchman, Wulfeck, and Ellis Weismer in 1999, retaining the key features and variety of verbs of the original design. It was administered to 424 typically developing children aged 5;0 to 11;6 years.

Outcomes & Results: The short version reduced administration time by two-thirds to around 5–8 minutes. Normative data revealed developmental progression in performance throughout the primary school years, with the task exhibiting ceiling effects in 29% of children by age 11 years. Expected and impaired performance indicators are presented by age band, that is, 5, 6, 7, 8, 9, 10, and 11 years. Comparisons between identified children with specific language impairment and typically developing children revealed significant differences in performance. The PTT-20 correlated highly with the full 52-item task and had good internal consistency.

Conclusions & Implications: The PTT-20 can be a useful tool in the identification and assessment of young school-age children with suspected language difficulties. It can also be used in research and practice as a benchmark against which to compare the ability of children with identified language impairments.

Jemima

The Salon Series provided an opportunity to present the work "Jemima". "Jemima" plays with multiple physicalities, performance states and expression as they jostle up against each other al at once. The jostling in the moment of performance creates a viscosity in the musculature, a tension, that also creates an intensity in performance. The discussion post performances provided an opportunity to articulate discoveries made in the studio prior to performance and also insights from performance. The questions asked by audiences have further stimulated studio practice as research. 

‘Till death do us part : judging the men who kill their intimate partners

This paper examines the construction of masculinity in judge’s sentencing remarks across seventeen cases of male perpetrated intimate femicide sentenced between March 2005 and May 2007 in the Victorian Supreme Court. Using a narrative analysis of sentencing transcripts it investigates how ideal understandings of hegemonic masculinity are used in judicial decision making to condemn or sympathise with male offenders of intimate femicide. The findings illustrate the profound influence that traditional understandings of masculinity and fatherhood still have on current sentencing practises despite the current climate of homicide law reform both within Australia and overseas. Whilst this paper did not directly assess the impact of recent homicide law reforms, specifically provocation, it is explicitly concerned with the continued influence of gender norms and bias at the sentencing stage of the legal process. As such, it provides a preliminary illustration of the key role that judges play in advocating or rejecting change within the criminal justice system, and more broadly legitimising attitudes about male violence against women throughout society. In condoning the use of extreme violence, in any context, judges send a message to society that such behaviour is either generally or specifically acceptable and accommodated within a legal framework.
