The forthcoming NIST’s Advanced Hash Standard (AHS) competition to select SHA-3 hash function requires that each candidate hash function submission must have at least one construction to support FIPS 198 HMAC application. As part of its evaluation, NIST is aiming to select either a candidate hash function which is more resistant to known side channel attacks (SCA) when plugged into HMAC, or that has an alternative MAC mode which is more resistant to known SCA than the other submitted alternatives. In response to this, we perform differential power analysis (DPA) on the possible smart card implementations of some of the recently proposed MAC alternatives to NMAC (a fully analyzed variant of HMAC) and HMAC algorithms and NMAC/HMAC versions of some recently proposed hash and compression function modes. We show that the recently proposed BNMAC and KMDP MAC schemes are even weaker than NMAC/HMAC against the DPA attacks, whereas multi-lane NMAC, EMD MAC and the keyed wide-pipe hash have similar security to NMAC against the DPA attacks. Our DPA attacks do not work on the NMAC setting of MDC-2, Grindahl and MAME compression functions.

This paper presents an extension to the Rapidly-exploring Random Tree (RRT) algorithm applied to autonomous, drifting underwater vehicles. The proposed algorithm is able to plan paths that guarantee convergence in the presence of time-varying ocean dynamics. The method utilizes 4-Dimensional, ocean model prediction data as an evolving basis for expanding the tree from the start location to the goal. The performance of the proposed method is validated through Monte-Carlo simulations. Results illustrate the importance of the temporal variance in path execution, and demonstrate the convergence guarantee of the proposed methods.

This paper reports on the views of Singaporean teachers of a mandated curriculum innovation aimed at changing the nature of games pedagogy within the physical education curriculum framework in Singapore. Since its first appearance over 20 years ago, Teaching Games for Understanding (TGfU), as an approach to games pedagogy has gathered support around the world. Through a process of evolution TGfU now has many guises and one of the latest of these is the Games Concept Approach (GCA) a name given to this pedagogical approach in Singapore. As part of a major national curricular reform project the GCA was identified as the preferred method of games teaching and as a result was mandated as required professional practice within physical education teaching. To prepare teachers for the implementation phase, a training program was developed by the National Institute of Education in conjunction with the Ministry of Education and well known experts in the field from the United States. For this part of the study, 22 teachers from across Singapore were interviewed. The data were used to create three fictional narratives, a process described by Sparkes (2002a) and used more recently by Ryan (2005) in the field of literacy. The stories were framed using Foucault’s (1980/1977) notion of governmentality and Bernstein’s (1996) notion of regulative discourse. The narratives reveal tales of confusion, frustration but also of hope and enthusiasm.

Introduction to Youth Services is a second year Social Work and Human Services unit. In this unit a reflective writing task was introduced to assess students’ reflections on an ongoing tutorial discussion to which they contributed. The discussion was based on a fictional young person each tutorial group ‘worked with’ across eight weeks of a semester. In developing the process and the criteria for the reflective journal, the ideas raised by the Teaching and Assessing Reflective Learning (TARL) in Higher Education project (see Chap. 2) were utilised, scaffolding the work with resources and submission of a draft. The students were also invited to choose the form of reflective process they used, it could be a written journal but did not need to be. The evidence exemplified that a reflective journal is an effective tool for students to record their developing understanding regarding the concept that issues people experience are complex and compounding. Importantly, it was also a useful vehicle for students to begin to consider the impacts of their own and others’ values and beliefs on their response to the issues raised within the case discussion. The reflective journal also helped participants to consider how this learning contributes to the ongoing development of their professional practice framework.

Polybrominated diphenyl ethers (PBDEs) are considered to be a cost effective and efficient way to reduce flammability therefore reducing harm caused by fires. PBDEs are incorporated into a variety of manufactured products and are found worldwide in biological and environmental samples (e.g. Hites et al. 2004). Unlike other persistent organic pollutants there is limited data on PBDE concentrations by age and/or other population specific factors. Some studies have shown no variation in adult serum PBDE concentrations with age (e.g. Mazdai et al., 2003, Meironyte Guvenius et al., 2003) while Petreas et al. (2003) and Schecter et al. (2005) found results to be suggestive of an age trend in adult data but no statistically significant correlation was found. In addition to the data on adult concentrations there is limited data which investigates the levels of PBDEs in infants and young children. Fangström et al. (2005) showed that in seven year olds there was no difference in PBDE concentration when compared to adult concentrations. While Thomsen et al. (2002, 2005) found the concentration of PBDEs in pooled samples of blood serum from a 0-4 years age group to be higher than other age groups (4 to > 60 years). In addition, a family of four was studied in the U.S. and the concentrations were found to be greatest in the 18-month-old infant followed by the 5 year old child, then the mother and father (Fischer et al., 2006). The objectives of this study were to assess age, gender and regional trends of PBDE concentrations in a representative sample of the Australian population.

Polybrominated diphenylethers (PBDEs) are widely used as flame retardants in polymer materials, textiles, electronic boards and various other materials. Technical PBDE preparations are produced as mixtures of mainly penta-, octa- or decabrombiphenyl ethers1,2. PBDEs are structurally similar to other environmental pollutants like dioxins and PCBs, they are lipophilic and persistent compounds and are widespread in the environment. To date, no information is available on the levels of PBDEs in human serum in Australia. In 2003, more than 9000 blood samples were collected in Australia as part of the National Dioxins Program. The aim of this study was to evaluate PBDE concentrations in these samples, focusing on one age group.

Unprecedented policy attention to early childhood education internationally has highlighted the crucial need for a skilled early years workforce. Consequently, professional development of early years educators has become a global policy imperative. At the same time, many maintain that professional development research has reached an impasse. In this paper, we offer a new approach to addressing this impasse. In contrast to calls for a redesign of comparative studies of professional development programs, or for the refinement of researcher-constructed professional development evaluation frameworks, we argue the need to cultivate what we refer to as an ‘evaluative stance’ amongst all involved in making decisions about professional development in the early years – from senior bureaucrats with responsibilities for funding professional development programs to individual educators with choices about which professional development opportunities to take up. Drawing on three bodies of literature -- evaluation capacity building, personal epistemology, and co-production -- that, for the most part, have been overlooked with respect to early years professional learning this paper proposes a conceptual framework to explain why cultivating an evaluative stance in professional development decision-making has rich possibilities for systemic, sustainable, and transformative change in early years education.

Polybrominated diphenyl ethers (PBDEs), a common class of brominated flame retardants, are a ubiquitous part of our built environment, and for many years have contributed to improved public safety by reducing the flammability of everyday goods. Recently, PBDEs have come under increased international attention because of their potential to impact upon the environment and human health. Some PBDE compounds have been nominated for possible inclusion on the Stockholm Convention on Persistent Organic Pollutants, to which Australia is a Party. Work under the Stockholm Convention has demonstrated the capacity of some PBDEs to persist and accumulate in the environment and to be carried long distances. Much is unknown about the impact of PBDEs on living organisms, however recent studies show that some PBDEs can inhibit growth in colonies of plankton and algae and depress the reproduction of zooplankton. Laboratory mice and rats have also shown liver disturbances and damage to developing nervous systems as a result of exposure to PBDEs. In 2004, the Australian Government Department of the Environment and Water Resources began three studies to examine levels of PBDEs in aquatic sediments, indoor environments and human blood, as knowledge about PBDEs in Australia was very limited. The aim of these studies was to improve this knowledge base so that governments were in a better position to consider appropriate management actions. Due to the high costs for laboratory analysis of PBDEs, the number of samples collected for each study was limited and so caution is required when interpreting the findings. Nevertheless, these studies will provide governments with an indication of how prevalent PBDEs are in the Australian population and the environment and will also contribute to international knowledge about these chemicals. The Department of the Environment and Water Resources will be working closely with othergovernment agencies, industry and the community to investigate any further action that may be required to address PBDEs in Australia.

Directed by Alex Proyas, the Knowing is an action-packed science-fiction disaster movie. A well-known Australian director working in Hollywood, Proyas has developed an international reputation for stylised fantasy and science-fiction movies, including the neo-gothic movie The Crow (1994), the complex science-fiction film Dark City (1998), and the adaptation of Isaac Asimov’s sci-fi classic I, Robot (2004) which earned almost US$350 million theatrically worldwide. Knowing was produced for US$50 million and relies heavily upon special effects (including a visually impressive sequence of the world being destroyed) and high-octane action sequences (including a notable plane crash). Knowing’s cast included Australian actors, Rose Byrne and Ben Mendelsohn, and American actor Nicolas Cage. While Knowing received typically poor critical reviews, the movie performed well at the box-office earning over US$183 million worldwide.

Like most of Stephan Elliott’s movies, A Few Best Men is difficult to discuss without focusing on the director himself. A wedding-gone-wrong comedy, A Few Best Men is Elliott’s first Australian feature film in seventeen years. After directing the low-budget crime-thriller Frauds (1993), Elliott achieved worldwide success as writer-director of the Oscar-winning road movie Adventures of Priscilla, Queen of the Desert (1994). A quirky and visually striking film about two drag-queens and a transsexual’s journey across the harsh Australian outback in a bus named Priscilla, the movie earned over US$70 million at the international box-office and became an instant Australian classic. Elliott’s career, however, self-destructed soon after...

Australia has a long history of policy attention to the education of poor and working-class youth (Connell, 1994), yet currently on standardized educational outcomes measures the gaps are widening in ways that relate to social background, including race, location and class. An economic analysis of school choice in Australia reveals that a high proportion of government school students now come from lower Socio-Economic Status (SES) backgrounds (Ryan & Watson, 2004), indicating a trend towards a gradual residualisation of the poor in government schools, with increased private school enrolments as a confirmed national trend. The spatial distribution of poverty and the effects on school populations are not unique to Australia (Lupton, 2003; Lipman, 2011; Ryan, 2010). Raffo and colleagues (2010) recently provided a synthesis of socially critical approaches towards schooling and poverty arguing that what is needed are shifts in the balances of power to reposition those within the educational system as having some say in the ways schooling is organized. ‘Disadvantaged’ primary schools are not a marginal concern for education systems, but now account for a large and growing number of schools that serve an ever increasing population being made redundant, in part-time precarious work, under-employed or unemployed (Thomson 2002; Smyth, Down et al 2010). In Australia, the notion of the ‘disadvantaged’ school now refers to those, mostly public schools, being residualised by a politics of parental choice that drives neoliberalising policy logic (Bonner & Caro 2007; Hattam & Comber, forthcoming 2014; Thomson & Reid, 2003)...

Pre-service teacher education institutions are large and complex organizations, which are notoriously difficult to change. One factor is that many change efforts focus largely on individual pre-service teacher educators altering their practice. We report here on our experience using a model for effecting change, which views pre-service teacher education institutions and educators as a part of a much broader system. We identified numerous possibilities for, and constraints on, embedding change, but focus only on two in this paper: participants’ knowledge of change strategies and their leadership capacities. As a result of our study findings and researcher reflections, we argue that being a leader in an academic area within pre-service teacher education does not equate to leadership knowledge or skills to initiate and enact systems-wide change. Furthermore, such leadership capacities must be explicitly developed if education for sustainability is to become embedded in pre-service teacher education.
