The focus of governments on increasing active travel has motivated renewed interest in cycling safety. Bicyclists are up to 20 times more likely to be involved in serious injury crashes than drivers so understanding the relationship among factors in bicyclist crash risk is critically important for identifying effective policy tools, for informing bicycle infrastructure investments, and for identifying high risk bicycling contexts. This study aims to better understand the complex relationships between bicyclist self reported injuries resulting from crashes (e.g. hitting a car) and non-crashes (e.g. spraining an ankle) and perceived risk of cycling as a function of cyclist exposure, rider conspicuity, riding environment, rider risk aversion, and rider ability. Self reported data from 2,500 Queensland cyclists are used to estimate a series of seemingly unrelated regressions to examine the relationships among factors. The major findings suggest that perceived risk does not appear to influence injury rates, nor do injury rates influence perceived risks of cycling. Riders who perceive cycling as risky tend not to be commuters, do not engage in group riding, tend to always wear mandatory helmets and front lights, and lower their perception of risk by increasing days per week of riding and by increasing riding proportion on bicycle paths. Riders who always wear helmets have lower crash injury risk. Increasing the number of days per week riding tends to decrease both crash injury and non crash injury risk (e.g. a sprain). Further work is needed to replicate some of the findings in this study.

This paper offers an overview of the key characteristics of “fake” news in the Australian national context. Focusing on two television shows – The Norman Gunston Show and NEWStopia – it historicizes “fake” news within Australian television culture, situating it as part of a broader tradition of what Turner (1989) calls “Transgressive TV.” After analyzing the core comedic themes, styles, and intertextual relationships of both shows, the paper concludes that, although news parody in Australia has tended to be highly fictionalized, it may nevertheless play a vital role in helping viewers better understand generic devices that frame and govern “real” television news.

Depleting fossil fuel resources and increased accumulation of greenhouse gas emissions are increasingly making electrical vehicles (EV) attractive option for the transportation sector. However uncontrolled random charging and discharging of EVs may aggravate the problems of an already stressed system during the peak demand and cause voltage problems during low demand. This paper develops a demand side response scheme for properly integrating EVs in the Electrical Network. The scheme enacted upon information on electricity market conditions regularly released by the Australian Energy Market Operator (AEMO) on the internet. The scheme adopts Internet relays and solid state switches to cycle charging and discharging of EVs. Due to the pending time-of-use and real-price programs, financial benefits will represent driving incentives to consumers to implement the scheme. A wide-scale dissemination of the scheme is expected to mitigate excessive peaks on the electrical network with all associated technical, economic and social benefits.

The purpose of this paper is to study the profiling of property, plant and equipment (PPE) contributions in Australia and Malaysia construction companies. A company’s worth is usually based on the listed share price on the stock exchange. In arriving at the net profit, the contribution of PPE in the company’s assets is somehow being neglected. This paper will investigate the followings; firstly the level of PPE contribution in the construction firms by comparing the PPE contributions to the company’s asset as a whole which includes fixed (non-current) assets and current assets. This will determine the true strength of the companies, rather than relying on the share prices alone. Secondly, the paper will determine the trend of company’s asset ownership to show the company’s performance of the PPE ownership during the period of study. The data is based on the selected construction companies listed on the Australian Stock Exchange (ASX) and Malaysian Stock Exchange, known as Bursa Malaysia. The profiling will help to determine the strength of the construction firms based on the PPE holding, and the level of PPE ownerships in the two countries construction firms during the period of study.

Given significant government attention to, and expenditure on, Indigenous equity in Australia, this article addresses a core problem: the lack of a sound understanding of Indigenous social attitudes and priorities. An account of cultural theory raises the likelihood of difference in outlook between Indigenous and non-Indigenous people, including those making and implementing policy. Yet, years of scholarly research and official statistical collections have overlooked potentially critical aspects of Indigineity. Suggestions of difference emerge from reference to the 2007 Australian Survey of Social Attitudes (AuSSA). If the attitudes recorded a small sample in this instrument manifest in the Indigenous population at large, policy priorities and directions should be reviewed and possibly revised. Despite inherent methodological difficulties, the article calls for targeted social attitude research among Australia's Indigenous peoples so that future policy can be better oriented and calibrated. The national benefits would outweigh the costs via better directed policy making.

The paper draws on a three year Australian Research Council funded project entitled Sexual Harassment in Australia: Context Outcomes and Prevention. The research to date suggests there is some slippage between legal definitions and community understandings of what constitutes sexual harassment. Moreover, while sexual harassment is often seen by the community and within organisations as the fault of one aberrant individual, in certain workplace contexts sexual harassment is used to ‘police the gender borders’, that is to exclude women and men who do not conform to the dominant workplace gender norms. This type of sexual harassment is a collective form of behaviour often perpetrated by co-workers in male-dominated workplaces which is designed to humiliate ‘outsiders’ so they appear incompetent and will be forced to leave the organisation. While much previous research that has focused on this type of sexual harassment has taken place in military and policing settings, our emerging findings suggest that it is present in a far broader range of workplace contexts. Prevention of this form of sexual harassment is challenging and goes to the heart of organisational culture and work organisation.

Retail employees are amongst the most vulnerable workers in the context of neoliberal market economies. In many countries, low paid retail employees comprise around 10 per cent of the workforce (ABS 2011). The retail labour market is typically highly feminised and youthful, with many employees in part time and various forms of precarious employment (Tailby & Pollert 2011). However, the industry and its trade unions have rarely been the focus of academic study (Tilly & Carré 2011). This paper thus aims to analyse and compare trade union strategies in the retail industry in Australia and New Zealand, by utilising findings from a larger comparative study. The respective unions studied are the Shop Distributive and Allied Workers Union (SDA) in Australia and the National Distribution Union (NDU) in New Zealand. Data from interviews with union officials at different levels and from different regional locations in Australia and NZ are analysed. Union policy documents are also utilised to support the empirical data. Key findings from the comparison of retail unions’ strategy in Australia and NZ include: 1) the importance of institutional factors and internal political differences in shaping and constraining union strategies; 2) different emphases on external relationships and variations in partnership approaches; 3) the need to recruit to ‘stand still’ by retail unions in both countries; and, 4) similarities and differences in the unions’ organising approaches. The paper concludes by examining the implications of these findings for retail unions’ strategic choices and their ability to deliver workplace justice for employees.

In the helter skelter of people legally and illegally seeking refuge in Australia, often overlooked are the realities of how to obtain that hoped for better life. One of the avenues chosen to achieve their dream is higher education; however, once enrolled in higher education many such students [termed Culturally and Linguistically Diverse (CALD)] find they are ill equipped to achieve academic success; they become overwhelmed by the pressures of study/family/work; and ultimately lose heart and their place at university. Life raft Australia has just become another disillusioning vehicle to a depressing future. This paper discusses how universities across Australia are now putting processes in place that will enable CALD students to confront and overcome academic and social barriers, and thus realise their dream of a better life. Exemplars from the University of Tasmania provide practical models of how higher education institutions, not only in Australia but globally can assist immigrant students to self actualize; to be empowered to become integral and successful members of the Australian community.

The mineral newberyite Mg(PO3OH)•3H2O is a mineral that has been found in caves such as the Skipton Lava Tubes (SW of Ballarat, Victoria, Australia), Moorba cave, Jurien Bay, Western Australia, and in the Petrogale Cave (Madura , Eucla, Western Australia). Because these minerals contain water, the minerals lend themselves to thermal analysis. The mineral newberyite is found to decompose at 145°C with a water loss of 31.96%, a result which is very close to the theoretical value. The result shows that the mineral is not stable in caves where the temperature exceeds this value. The implication of this result rests with the removal of kidney stones, which have the same composition as newberyite. Point heating focussing on the kidney stone results in the destruction of the kidney stone.

Thermogravimetric analysis has been used to determine the thermal stability of the mineral stercorite H(NH4)Na(PO4)·4H2O. The mineral stercorite originated from the Petrogale Cave, Madura, Eucla, Western Australia. This cave is one of many caves in the Nullarbor Plain in the South of Western Australia. The mineral is formed by the reaction of bat guano chemicals on calcite substrates. Upon thermal treatment the mineral shows a strong decomposition at 191°C with loss of water and ammonia. Other mass loss steps are observed at 158, 317 and 477°C. Ion current curves indicate a gain of CO2 at higher temperature and are attributed to the thermal decomposition of calcite impurity.

As part of the Australian Government’s Clean Energy Plan, the Government has attempted to harness the legal innovation of the tradeable emissions unit, within a capped carbon trading system, to reduce greenhouse gas emissions. Such an approach promises to send a price signal to the market which will influence emitting behaviours and reduce our emissions in a cost-effective manner. However, if the carbon trading scheme is to successfully achieve cost-effective emissions reductions then the carbon market must be supported by an appropriate legal framework. This paper will consider the key features of the Australian Carbon Pricing Mechanism, including the Carbon Farming Initiative, and critique whether it has all the hallmarks of an effective legal framework to reduce Australia’s net greenhouse gas emissions. The likely future of the trading scheme, following the 2013 elections, will also be addressed.

This paper investigates energy saving potential of commercial building by living wall and green façade system using Envelope Thermal Transfer Value (ETTV) equation in Sub-tropical climate of Australia. Energy saving of four commercial buildings was quantified by applying living wall and green façade system to the west facing wall. A field experimental facility, from which temperature data of living wall system was collected, was used to quantify wall temperatures and heat gain under controlled conditions. The experimental parameters were accumulated with extensive data of existing commercial building to quantify energy saving. Based on temperature data of living wall system comprised of Australian native plants, equivalent temperature of living wall system has been computed. Then, shading coefficient of plants in green façade system has been included in mathematical equation and in graphical analysis. To minimize the air-conditioned load of commercial building, therefore to minimize the heat gain of commercial building, an analysis of building heat gain reduction by living wall and green façade system has been performed. Overall, cooling energy performance of commercial building before and after living wall and green façade system application has been examined. The quantified energy saving showed that only living wall system on opaque part of west facing wall can save 8-13 % of cooling energy consumption where as only green façade system on opaque part of west facing wall can save 9.5-18% cooling energy consumption of commercial building. Again, green façade system on fenestration system on west facing wall can save 28-35 % of cooling energy consumption where as combination of both living wall on opaque part of west facing wall and green façade on fenestration system on west facing wall can save 35-40% cooling energy consumption of commercial building in sub-tropical climate of Australia.
