What happened to the education revolution? : new media technologies and the Australian curriculum : constraints and possibilities

This chapter investigates the place of new media in Queensland in the light of the Australian curriculum. ‘Multimodal texts’ in English are being defined as largely electronically ‘created’ and yet restricted access to digital resources at the chalkface may preclude this work from happening. The myth of the ‘digital native’ (Prensky, 2007), combined with the reality of the ‘digital divide’ coupled with technophobia amongst some quite experienced teachers, responsible for implementing the curriculum, paints a picture of constraints. These constraints are due in part to protective state bans in Queensland on social networking sites and school bans on mobile phone use. Some ‘Generation next’ will have access to digital platforms for the purpose of designing texts at home and school, and others will not. Yet without adequate Professional Development for teachers and substantially increased ICT infrastructure funding for all schools, the way new media and multimodal opportunities are interpreted at state level in the curriculum may leave much to be desired in schools. This chapter draws on research that I recently conducted on the professional development needs of beginning teachers, as well as a critical reading of the ACARA policy documents.

Characterisation and source identification of selected pollutants in house dust

House dust is a heterogeneous matrix, which contains a number of biological materials and particulate matter gathered from several sources. It is the accumulation of a number of semi-volatile and non-volatile contaminants. The contaminants are trapped and preserved. Therefore, house dust can be viewed as an archive of both the indoor and outdoor air pollution. There is evidence to show that on average, people tend to stay indoors most of the time and this increases exposure to house dust. The aims of this investigation were to: " assess the levels of Polycyclic Aromatic Hydrocarbons (PAHs), elements and pesticides in the indoor environment of the Brisbane area; " identify and characterise the possible sources of elemental constituents (inorganic elements), PAHs and pesticides by means of Positive Matrix Factorisation (PMF); and " establish the correlations between the levels of indoor air pollutants (PAHs, elements and pesticides) with the external and internal characteristics or attributes of the buildings and indoor activities by means of multivariate data analysis techniques. The dust samples were collected during the period of 2005-2007 from homes located in different suburbs of Brisbane, Ipswich and Toowoomba, in South East Queensland, Australia. A vacuum cleaner fitted with a paper bag was used as a sampler for collecting the house dust. A survey questionnaire was filled by the house residents which contained information about the indoor and outdoor characteristics of their residences. House dust samples were analysed for three different pollutants: Pesticides, Elements and PAHs. The analyses were carried-out for samples of particle size less than 250 µm. The chemical analyses for both pesticides and PAHs were performed using a Gas Chromatography Mass Spectrometry (GC-MS), while elemental analysis was carried-out by using Inductively-Coupled Plasma-Mass Spectroscopy (ICP-MS). The data was subjected to multivariate data analysis techniques such as multi-criteria decision-making procedures, Preference Ranking Organisation Method for Enrichment Evaluations (PROMETHEE), coupled with Geometrical Analysis for Interactive Aid (GAIA) in order to rank the samples and to examine data display. This study showed that compared to the results from previous works, which were carried-out in Australia and overseas, the concentrations of pollutants in house dusts in Brisbane and the surrounding areas were relatively very high. The results of this work also showed significant correlations between some of the physical parameters (types of building material, floor level, distance from industrial areas and major road, and smoking) and the concentrations of pollutants. Types of building materials and the age of houses were found to be two of the primary factors that affect the concentrations of pesticides and elements in house dust. The concentrations of these two types of pollutant appear to be higher in old houses (timber houses) than in the brick ones. In contrast, the concentrations of PAHs were noticed to be higher in brick houses than in the timber ones. Other factors such as floor level, and distance from the main street and industrial area, also affected the concentrations of pollutants in the house dust samples. To apportion the sources and to understand mechanisms of pollutants, Positive Matrix Factorisation (PMF) receptor model was applied. The results showed that there were significant correlations between the degree of concentration of contaminants in house dust and the physical characteristics of houses, such as the age and the type of the house, the distance from the main road and industrial areas, and smoking. Sources of pollutants were identified. For PAHs, the sources were cooking activities, vehicle emissions, smoking, oil fumes, natural gas combustion and traces of diesel exhaust emissions; for pesticides the sources were application of pesticides for controlling termites in buildings and fences, treating indoor furniture and in gardens for controlling pests attacking horticultural and ornamental plants; for elements the sources were soil, cooking, smoking, paints, pesticides, combustion of motor fuels, residual fuel oil, motor vehicle emissions, wearing down of brake linings and industrial activities.

ACE research briefing paper 005: Global Entrepreneurship Monitor (GEM) - Australia 2011 National Report

This report maps the current state of entrepreneurship in Australia using data from the Global Entrepreneurship Monitor (GEM) for the year 2011. Entrepreneurship is regarded as a crucial driver for economic well-being. Entrepreneurial activity in new and established firms drives innovation and creates jobs. Entrepreneurs also fuel competition thereby contributing indirectly to market and productivity growth along with improving competitiveness of the national economy. Given the economic landscape that exists as a result of the global financial crisis (GFC), it is probably more important than ever for us to understand the effects and drivers of entrepreneurial activity and attitudes in Australia. The central finding of this report is that entrepreneurship is certainly alive and well in Australia. With 10.5 per cent of the adult population involved in setting up a new business or owning a newly founded business as measured by the total entrepreneurial activity rate (TEA) in 2011, Australia ranks second only to the United States among the innovation-driven (developed) economies. Compared with 2010 the TEA rate has increased by 2.7 percentage points. Furthermore, in regard to employee entrepreneurial activity (EEA) rate in established firms, Australia ranks above average. According to GEM data, 5 per cent of the adult population is engaged in developing or launching new products, a new business unit or subsidiary for their employer. Further analysis of the GEM data also clearly shows that Australia compares well with other major economies in terms of the ‘quality’ of entrepreneurial activities being pursued. Indeed, it is not only the quantity of entrepreneurs but also the level of their aspirations and business goals that are important drivers for economic growth. On average, for each business started in Australia driven by the lack of alternatives for the founder to generate income from any other source, there are five other businesses started where the founders specifically want to take advantage of a business opportunity that they believe will increase their personal income or independence. With respect to innovativeness, 31 per cent of Australian new businesses offer products or services which they consider to be new to customers or where very few, or in some cases no, other businesses offer the same product or service. Both these indicators are higher than the average for innovation-driven economies. Somewhat below average is the international orientation of Australian entrepreneurs whereby only 12 per cent aim at having a substantial share of customers from international markets. So what drives this high quantity and quality of entrepreneurship in Australia? The analysis of the data suggests it is a combination of both business opportunities and entrepreneurial skills. It seems that around 50 per cent of the Australian population identify opportunities for a start-up venture and believe that they have the necessary skills to start a business. Furthermore, a large majority of the Australian population report that high media attention for entrepreneurship provides successful role models for prospective entrepreneurs. As a result, 12 per cent of our respondents have expressed the intention to start a business within the next three years. These numbers are all well above average when compared to the other major economies. With regard to gender, the GEM survey shows a high proportion of female entrepreneurs. Approximately 8.4 per cent of adult females are actually involved in setting up a business or have recently done so. Although this female TEA rate is slightly down from 2010, Australia ranks second among the innovation-driven economies. This paints a healthy picture of access to entrepreneurial opportunities for Australian women.

Are we keeping the bastards honest? Perceptions of corruption, integrity and influence on politics

The words of the late Don Chipp, the founder of the Australian Democrats, have a perennial relevance to politics. When Chipp talked about ‘keeping the bastards honest’, it related to a minor political party playing a role of keeping the major political parties true to their word (Warhurst 1997). Yet it is also a democratic role that citizens play on an ongoing basis, particularly through the mechanism of elections. At the ballot box, governments that are widely perceived to have acted with a lack of integrity are roundly punished. This chapter explores public opinion on issues of integrity, corruption, influence and trust in politics and politicians in Australia. The evidence paints a differentiated picture of a public which sees little sign of overtly corrupt political practices but on the other hand does not feel terribly influential and is not always confident of fair treatment from public officials...

The national railway of Sarah Island : Richard Flanagan's Gould's Book of Fish

In the latter half of the nineteenth century the railway became an emblem of technological advancement, stood for the improvement and progression of European life, and became a recognizable symbol for the achievements of governments and citizens. The implementation and use of the railway became closely linked with notions of national identity and character. The railway became an identifiable artefact in official history but at the same time it became a part of everyday life. Richard Flanagan’s Gould’s Book of Fish retells the life-story of a fictionalized convict sent to Sarah Island and who paints fish, eventually he metamorphoses into one. It could be thought that a novel set in convict times would have little to do with notions of national identity, technological advancement, and railway travel. However, Richard Flanagan, in this very complex, almost surreal, novel, has used the construction of a fictional national railway as one of the ways to explore Australia's complex relationship with history and space. The novel tells of the plans of a history-loving Commandant and his desire to build a national railway on Sarah Island. This paper explores how Sarah Island becomes a metonym for Australia as a whole and Flanagan's novel takes on a metaphysical dimension as he reveals the struggles that emerge when official history collides with non-official versions. The fabulations of the novel contribute to an historical reconstruction of the spatial/architectural history of the Tasmanian colonial project.

When Japanese law goes pop

This article explores the extent to which the growth in law-themed popular culture since the turn of the century, especially television shows, signals a shift in popular attitudes towards law. Four decades of research into Japanese legal consciousness has called into question the extent to which there is a Japanese cultural aversion to Jaw, with most scholars expressing doubt over whether culture properly explains the comparatively low litigation rates in Japan compared to other industrialised nations. This article argues that popular culture, although not without its limitations, offers new clues into how legal consciousness is developing and changing in 21st Century Japan. The article concludes that popular culture paints a picture of a greater readiness by Japanese people to engage with Jaw, although scepticism remains about the law's promise to achieve justice and social solidarity.

Litigiousness in Australia: Lessons from comparative law

How litigious are Australians? Although quantitative studies have comprehensively debunked the fear of an Australian civil justice system in crisis, the literature has yet to address the qualitative public policy question of whether Australians are under- or over-using the legal system to resolve their disputes. On one view, expressed by the insurance industry, the mass media and prominent members of the judiciary, Australia is moving towards an American-style hyper-litigiousness. By contrast, Australian popular culture paints the typical Australian as culturally averse to formal rights assertion. This article explores the comparative law literature on litigiousness in two jurisdictions that have attracted significant scholarly attention — the United States and Japan. More specifically, it seeks to draw lessons from this literature for both understanding litigiousness in modern Australia and framing future research projects on the issue.

Microplastic ingestion by scleractinian corals

We report for the first time the ingestion of microplastics by scleractinian corals, and the presence of microplastics in coral reef waters adjacent to inshore reefs on Australia’s Great Barrier Reef (GRE, 18°31′S 146°23′E). Analysis of samples from sub-surface plankton tows conducted in close proximity to inshore reefs on the central GBR revealed microplastics, similar to those used in marine paints and fishing floats, were present in low concentrations at all water sampling locations. Experimental feeding trials revealed that corals mistake microplastics for prey and can consume up to ~50 μg plastic cm−2 h−1, rates similar to their consumption of plankton and Artemia nauplii in experimental feeding assays. Ingested microplastics were found wrapped in mesenterial tissue within the coral gut cavity, suggesting that ingestion of high concentrations of microplastic debris could potentially impair the health of corals.

CFD Analysis of two phase flow with a prediction of torque demand of a Bi-lobe rotor of a mixing chamber

An attempt to study the fluid dynamic behavior of two phase flow comprising of solid and liquid with nearly equal density in a geometrical case that has an industrial significance in theareas like processing of polymers, food, pharma ceutical, paints. In this work,crystalline silica is considered as the dispersed medium in glycerin. In the CFD analysis carried out,the two phase components are considered to be premixed homogeneously at the initial state. The flow in a cylinder that has an axially driven bi-lobe rotor, a typical blender used in polymer industry for mixing or kneading to render the multi-component mixture to homogeneous condition is considered. A viscous, incompressible, isothermal flow is considered with an assumption that the components do not undergo any physical change and the solids are rigid and mix in fully wetting conditions. Silica with a particle diameter of 0.4 mm is considered and flow is analyzed for different mixing fractions. An industry standard CFD code is used for solving 3D-RANS equations. As the outcome of the study the torque demand by the bi-lobe rotor for different mixture fractions which are estimated show a behavioral consistency to the expected physical phenomena occurring in the domain considered.

Economics of co-managing water quality and invasive species for California and Baja California coastal boats

Regulatory action to protect California’s coastal water quality from degradation by copper from recreational boats’ antifouling paints interacts with efforts to prevent transport of invasive, hull-fouling species. A copper regulatory program is in place for a major yacht basin in northern San Diego Bay and in process for other major, California boat basins. “Companion” fouling control strategies are used with copper-based antifouling paints, as some invasive species have developed resistance to the copper biocide. Such strategies are critical for boats with less toxic or nontoxic hull coatings. Boat traffic along over 3,000 miles of coastline in California and Baja California increases invasive species transport risks. For example, 80% of boats in Baja California marinas are from the United States, especially California. Policy makers, boating businesses and boat owners need information on costs and supply-side capacity for effective fouling control measures to co-manage water quality and invasive species concerns.

From the individual to the community and beyond: water quality, stress indicators and key species in coastal waters

This review examines water quality and stress indicators at levels of organisation from the individual to the community and beyond by means of three case studies concentrating on rocky shores within the north-east Atlantic. Responses of dogwhelks (Nucella) to tributyltin pollution from antifouling paints is examined as the main case study. There are effects at the individual level (development of male sexual characteristics in the female leading to effective sterility) and population level (reduction in juveniles, few females and eventual population disappearance of dogwhelks in badly contaminated areas) but information on community level effects of dogwhelk demise is sparse. Such effects were simulated by dogwhelk removal experiments on well studied, moderately exposed ledges on shores on the Isle of Man. The removal of dogwhelks reduced the size and longevity of newly established Fucus clumps that had escaped grazing. Removal of dogwhelks also increased the likelihood of algal escapes. In a factorial experiment dogwhelks were shown to be less important than limpets \{Patella) in structuring communities but still had a significant modifying effect by increasing the probability of algal escapes. Community level responses to stress on rocky shores are then explored by reference to catastrophic impacts such as oil spills, using the Torrey Canyon as a case study. Recovery of the system in response to this major perturbation took between 10-15 years through a series of damped oscillations. The final case study is that of indicators of ecosystem level change in response to climate fluctuations, using ratios of northern \{Semibalanus balanoides) and southern (Chthamalus spp.) barnacles. Indices derived from counts on the shore show good correlations with inshore sea-water temperatures after a 2-year lag phase. The use of barnacles to measure offshore changes is reviewed. The discussion considers the use of bioindicators at various levels of organisation.

Nas Minas... por entre typos, jornais e tintas: sociabilidade impressa e debate político na Província das Gerais (1823-1831)

Durante a década de 1820, a província de Minas Gerais assistiu ao surgimento da imprensa periódica, em algumas de suas vilas e cidades. Dentre elas podemos destacar Ouro Preto e São João dEl-Rey, que assistiram ao nascimento dos periódicos O Universal e os Astro de Minas e O Amigo da Verdade, respectivamente. O primeiro veio à luz em 1825, e teve com principal responsável, o político e estadista Bernardo Pereira de Vasconcelos. Por sua vez o Astro de Minas surge dois anos depois em 1287. O político e comerciante Baptista Caetano dAlmeida esteve a frente de sua implementação e impressão, contribuindo também como redator. Em 1829 foi a vez do O Amigo da Verdade que teve como colaborador, o vigário da Matriz de Nossa Senhora do Pilar, em São João dEl-Rey, Luís José Dias Custódio. Esses periódicos foram responsáveis pela mobilização de opiniões públicas, retratando a realidade de acordo com as visões de mundo de seus redatores e responsáveis, além de funcionarem como importante agente histórico e instrumento político de grupos letrados na província de Minas Gerais. A partir da apreciação dos periódicos citados, o presente estudo tem como objetivo identificar e analisar a existência de uma rede de sociabilidade impressa entre os periódicos mineiros, além de perceber a imprensa como espaço do debate político, forjado pelas elites letradas mineiras, ao longo do Primeiro Reinado.

Pioneiros do design brasileiro no projeto de automóveis

Não se questiona que o design seja um saber naturalmente multidisciplinar. Os projetos da indústria automobilística ilustram esse ponto magistralmente: do ato de inventar à engenharia da produção; do design de exteriores aos interiores; das autopeças às diversas tintas. Projetos desenvolvidos em engenharia simultânea, produzidos em diversos países do mundo e montados onde quer que se mostre mais rentável. A moderna indústria automobilística mostra-se, nesse sentido, global. Mas como harmonizar os gostos e as legislações locais a essa estrutura produtiva internacional? Esta dissertação ilustra alguns aspectos da estratégia de projetos em design automobilístico tomando como base a experiência brasileira. Foram entrevistados os mais destacados designers brasileiros de automóveis dos pioneiros aos mais importantes profissionais contemporâneos. Embora as estratégias das empresas sejam diversas fato que impede uma única conclusão -, esta dissertação lança luzes sobre os desafios do desenvolvimento de projetos automobilísticos onde o projeto é global mas as vendas são locais.

Avaliação temporal da poluição por antiincrustantes organoestânicos no litoral do Estado do Rio de Janeiro: antes e após o banimento nacional e internacional

Tintas antifoulings são utilizadas para evitar a incrustação de organismos em estruturas submersas, especialmente casco de embarcações. Os compostos organoestânicos (OTs), utilizados nessas tintas, entre eles o tributilestanho, são desreguladores endócrinos e causaram diversos danos aos ecossistemas marinhos. No caso dos moluscos gastrópodes, esse tipo de poluição faz com que as fêmeas adquiram características masculinas, como vaso deferente e pênis, fenômeno esse conhecido como imposex. A Organização Marítima Internacional (IMO) estabeleceu o banimento de tintas à base de COEs nas embarcações, em 2008. No Brasil, a NORMAM 23, proibiu o uso em 2007, contudo a Marinha já havia suspendido seu uso desde 2003. Entretanto, efeitos deletérios destes compostos ainda são detectados em vários países, inclusive ao longo do litoral brasileiro. Esse trabalho teve como objetivo principal fazer uma avaliação temporal (1997-2012) da poluição por organestânicos na costa do Estado do Rio de Janeiro utilizando como bioindicador a espécie Stramonita haemastoma. A área de estudo abrangeu cinco regiões: Paraty, Ilha Grande, Baia de Ilha Grande, Baia de Guanabara e Arraial do Cabo. Análises químicas de butilestânicos foram feitas em sedimentos superficiais de mangues de Paraty (Mangue do Estaleiro e mangue do Saco do Mamanguá) e Ilha Grande (Mangue do Aventureiro) sendo os dois últimos considerados áreas de referência. Em cada estação de biomonitoramento foram coletados 30 indivíduos sexualmente adultos da espécie S. haemastoma, através de mergulho livre em apnéia e analisados através do método não destrutivo proposto por nosso grupo de pesquisa. Em todas as cinco áreas analisadas ao longo da costa do Estado do Rio de Janeiro foram registradas estações com altos índices de imposex. Apesar de muitas estações apresentarem diminuição nos índices, na maioria ocorreu um aumento ou conservação alta na porcentagem de imposex depois do banimento. As concentrações médias de butilestânicos no mangue (S1), perto de fontes locais, foram 205,7 16,8 ng (Sn) g-1 de TBT, 16,4 1,3 ng (Sn) g-1 de DBT e 10,0 2,9 ng (Sn) g-1 de MBT. Nas áreas de referência: mangue do Saco do Mamanguá (S2) foram 16,0 0,8 ng (Sn) g-1 de TBT, 10,1 1,4 ng (Sn) g-1 de DBT e 10,1 2,2 ng (Sn) g-1 de MBT e mangue do Aventureiro (S3) com 18,1 4,2 ng (Sn) g-1 de TBT, 15,3 0,5 ng (Sn) g-1 de DBT e 10,2 1,5 ng (Sn). g-1 de MBT. As taxas de degradação foram de 01, 1,3 e 1,4 respectivamente indicando inputs recentes desses compostos. Os resultados deste estudo indicam que carbono orgânico dissolvido e particulado, bem como xenoestrógenos podem estar interferindo no desenvolvimento da síndrome, levando a subestimação de avaliação do imposex. As concentrações de butilestânicos, além do aumento ou continuidade alta na incidência de imposex após o banimento na maioria das estações indicam que, apesar da proibição do uso do TBT em tintas antiiincrustantes no Brasil, elas ainda estão sendo utilizadas de forma ilegal, especialmente em pequenos barcos. Esse estudo é fundamental para se propor medidas de mitigação e controle dos compostos organoestânicos, até mesmo dos novos antifoulings TBT- free, que também possuem efeitos prejudiciais ao ambiente. Além disso, as áreas onde se registrou altos índices de imposex serão essenciais para o monitoramento dos efeitos desses novos antifoulings.
