Cyclododecane as support material for clean and facile transfer of large-area few-layer graphene

The transfer of chemical vapor deposited graphene is a crucial process, which can affect the quality of the transferred films and compromise their application in devices. Finding a robust and intrinsically clean material capable of easing the transfer of graphene without interfering with its properties remains a challenge. We here propose the use of an organic compound, cyclododecane, as a transfer material. This material can be easily spin coated on graphene and assist the transfer, leaving no residues and requiring no further removal processes. The effectiveness of this transfer method for few-layer graphene on a large area was evaluated and confirmed by microscopy, Raman spectroscopy, x-ray photoemission spectroscopy, and four-point probe measurements. Schottky-barrier solar cells with few-layer graphene were fabricated on silicon wafers by using the cyclododecane transfer method and outperformed reference cells made by standard methods.

Work Health and Safety Law and Policy

The third edition of Work Health and Safety Law and Policy continues to provide a plain English approach to explaining and analysing the law which regulates work health and safety in Australia. Providing broad coverage, this book focuses on the role that legal regulation plays in preventing work-related injury and disease, as well as the way in which the law contributes to rehabilitating and compensating injured and ill workers. This third edition focuses on the national model Work Health and Safety Bill 2009. The provisions of the model Bill are outlined, along with court decisions and other documentation that help interpret the provisions in new legislation enacting the model Bill. There is also a chapter in the book examining the national model Work Health and Safety Regulations 2011, and model codes of practice. The book includes three chapters on common law, statutory workers’ compensation provisions and rehabilitation. Tables summarising the key legal provisions of the major Australian Commonwealth, State and Territory workers’ compensation statutes have been updated and give quick and easy reference to points of legislation.

Kumarina and bidders voting in transfer schemes

Transfer schemes are an alternative means of acquiring control of a company to making a takeover bid under the provisions in Ch 6 of the Corporations Act 2001 (Cth). The recent decision Re Kumarina Resources Ltd [2013] FCA 549 overturned long-standing practice in relation to a certain type of transfer scheme. If followed, the decision would allow a “bidder” to vote at scheme meetings where the scheme consideration for the acquisition of the target shares are shares in another company, and the scheme results in a merger. But the bidder is not allowed to vote where the scheme consideration is cash. The article points out the difficulties arising from this decision and argues that it should not be followed. In providing a “no objection” statement, the Australian Securities and Investments Commission (ASIC) has created uncertainty as to the approach it will take towards the bidders being allowed to vote at scheme meetings where the scheme consideration for the acquisition of target shares are shares in another company. The article also points out that in providing the no objection statement in Kumarina, ASIC appears to have ignored breaches of s 606(1) of the Corporations Act. There is a pressing need for ASIC to clarify its position and, in particular, whether or not it will provide a no objection statement in respect of future transfer schemes where a bidder (or its parent company) votes at the scheme meeting.

Leader vision and diffusion of HR policy during change

Purpose – This paper utilizes diffusion of innovation theory in order to investigate and understand the relationships between HR policies on employee change-related outcomes. In addition, the aim is to explore the role of leader vision at different hierarchical levels in the organization in terms of the relationship of HR policy with employee change-related outcomes. Design/methodology/approach – This quantitative study was conducted in one large Australian government department undergoing major restructuring and cultural change. Data from 624 employees were analyzed in relation to knowledge of HR policies (awareness and clarity), leader vision (organizational and divisional), and change-related outcomes. Findings –Policy knowledge (awareness and clarity) does not have a direct impact on employee change-related outcomes. It is the implementation of policies through the divisional leader that begins to enable favorable employee outcomes. Research limitations/implications – Future research should employ a longitudinal design to investigate relationships over time, and also examine the importance of communication medium and individual preferences in relation to leader vision. Originality/value - This research extends the application of diffusion of innovation theory and leader vision theory to investigate the relationship between HR policy, leader vision, and employees’ change-related outcomes.

Indigenous livelihoods policy reference group: Research priorities identified from the first meeting, 28th April 2010

The CSIRO Indigenous Livelihoods Project sought to work with Indigenous communities, government and non-government stakeholders to bring together western science and Indigenous knowledge in order to understand the potential livelihood benefits of enterprises based on natural resource management. The research focus was to enhance livelihood opportunities for Indigenous communities derived from new enterprises and activities based on natural resource management in regional and remote Australia. Underpinning outcomes were: · Identification of effective policy and institutional arrangements required to establish and maintain sustainable livelihoods; · Improved systems understanding of factors that enhance or inhibit sustainable livelihoods based on natural resource management; · Tools and methods for measuring the livelihood benefits of natural resource management; · Education, training, employment and capacity building for Indigenous communities and researchers.

Theoretical modelling of momentum transfer function of bi-disperse porous media

The aim of this paper is to obtain the momentum transfer coefficient between the two phases, denoted by f and p, occupying a bi-disperse porous medium by mapping the available experimental data to the theoretical model proposed by Nield and Kuznetsov. Data pertinent to plate-fin heat exchangers, as bi-disperse porous media, were used. The measured pressure drops for such heat exchangers are then used to give the overall permeability which is linked to the porosity and permeability of each phase as well as the interfacial momentum transfer coefficient between the two phases. Accordingly, numerical values are obtained for the momentum transfer coefficient for three different fin spacing values considered in the heat exchanger experiments.

Evaluation of Indigenous justice programs.: final report / Project D, Safe Aboriginal Youth Patrol Programs in New South Wales and Northbridge Policy and Juvenile Aid Group in Western Australia

The Australian Government has provided funding to evaluate the effectiveness of Indigenous law and justice programs across five subject areas to identify the best approaches to tackling crime and justice issues and better inform government funding decisions in the future. This report presents the findings of subject area "D", which examined two different approaches to delivering community and night patrol services for young people: the Safe Aboriginal Youth Patrol programs in New South Wales, and the Northbridge Policy project (the Young People in Northbridge project), in Western Australia. Night patrols can address crime either directly or indirectly, by prevention work or by addressing the social causes of crime through community development.

Corporatizing the 'intellectual machinery' of government : the case of educational policy in Australia

This article analyses what it describes as the corporatization of the ‘intellectual machinery’ of government: the theories, knowledges, research and ‘know how’ utilized by political authorities to render the world thinkable, programmable and subject to intervention. Through an analysis of two key nodal points in national policy on teacher professional standards in Australia over the last decade, the article discloses a shift in the relation between expertise and politics. This is manifested, it is argued, in an increased reliance by policy authorities on corporatized forms of research produced by national and international private consulting firms, Think Tanks, and ‘policy entrepreneurs’ and a concomitant decrease in their reliance on free research produced largely by academics in institutions of higher education. The article seeks to account for this shift in terms of the ‘advanced liberal’ formula for rule which now characterizes government in contemporary Western polities.

What is plan B? Using Foucault's archaeology to enhance policy analysis

Many governments in western democracies conduct the work of leading their societies forward through policy generation and implementation. Despite government attempts at extensive negotiation, collaboration and debate, the general populace in these same countries frequently express feelings of disempowerment and undue pressure to be compliant, often leading to disengagement. Here we outline Plan B: a process for examining how policies that emerge from good intentions are frequently interpreted as burdensome or irrelevant by those on whom they have an impact. Using a case study of professional standards for teachers in Australia, we describe how we distilled Foucault’s notions of archaeology into a research approach centring on the creation of ‘polyhedrons of intelligibility’ as an alternative approach by which both policy makers and those affected by their policies may understand how their respective causes are supported and adversely affected.

Competition policy review : draft recommendations on competition laws

On 4 December 2013, the Prime Minister and the Minister for Small Business announced a “root and branch” review of Australia’s competition policy. The Minister for Small Business released the final Terms of Reference for the competition policy review on 27 March 2014, following consultation with the States and Territories, and announced the Review Panel headed by Professor Ian Harper. Under the terms of reference the Competition Policy Review Committee (the Harper Committee) is required to focus on three broad areas: •examining what can be done to create more competition in service areas such as health, education and intellectual property; •considering whether the structure and powers of the competition institutions (the ACCC , the NCC, the Tribunal and the AER) remain appropriate; and •examining the effectiveness of the competition provisions of the Competition and Consumer Act 2010 (Cth) (CCA) and laying down a broad framework through which the law can be streamlined and reformed over time.

Multiphase porous media model for heat and mass transfer during drying of agricultural products

Modelling of food processing is complex because it involves sophisticated material and transport phenomena. Most of the agricultural products such fruits and vegetables are hygroscopic porous media containing free water, bound water, gas and solid matrix. Considering all phase in modelling is still not developed. In this article, a comprehensive porous media model for drying has been developed considering bound water, free water separately, as well as water vapour and air. Free water transport was considered as diffusion, pressure driven and evaporation. Bound water assumed to be converted to free water due to concentration difference and also can diffuse. Binary diffusion between water vapour and air was considered. Since, the model is fundamental physics based it can be applied to any drying applications and other food processing where heat and mass transfer takes place in porous media with significant evaporation and other phase change.

Comparison of ocular modulation transfer function determined by a ray-tracing aberrometer and a double-pass system in early cataract patients

BACKGROUND: The evaluation of retinal image quality in cataract eyes has gained importance and the clinical modulation transfer functions (MTF) can obtained by aberrometer and double pass (DP) system. This study aimed to compare MTF derived from a ray tracing aberrometer and a DP system in early cataractous and normal eyes. METHODS: There were 128 subjects with 61 control eyes and 67 eyes with early cataract defined according to the Lens Opacities Classification System III. A laser ray-tracing wavefront aberrometer (iTrace) and a double pass (DP) system (OQAS) assessed ocular MTF for 6.0 mm pupil diameters following dilation. Areas under the MTF (AUMTF) and their correlations were analyzed. Stepwise multiple regression analysis assessed factors affecting the differences between iTrace- and OQAS-derived AUMTF for the early cataract group. RESULTS: For both early cataract and control groups, iTrace-derived MTFs were higher than OQAS-derived MTFs across a range of spatial frequencies (P < 0.01). No significant difference between the two groups occurred for iTrace-derived AUMTF, but the early cataract group had significantly smaller OQAS-derived AUMTF than did the control group (P < 0.01). AUMTF determined from both the techniques demonstrated significant correlations with nuclear opacities, higher-order aberrations (HOAs), visual acuity, and contrast sensitivity functions, while the OQAS-derived AUMTF also demonstrated significant correlations with age and cortical opacity grade. The factors significantly affecting the difference between iTrace and OQAS AUMTF were root-mean-squared HOAs (standardized beta coefficient = -0.63, P < 0.01) and age (standardized beta coefficient = 0.26, P < 0.01). CONCLUSIONS: MTFs determined from a iTrace and a DP system (OQAS) differ significantly in early cataractous and normal subjects. Correlations with visual performance were higher for the DP system. OQAS-derived MTF may be useful as an indicator of visual performance in early cataract eyes.
