Concentration levels of heavy metals and polycyclic aromatic hydrocarbons in car parks at Queensland University of Technology

This study investigates the level of pollutants (polycyclic aromatic hydrocarbons (PAHs) and heavy metals) in three car parks at QUT, one at Kelvin Grove campus and two at the Gardens Point campus. In addition, comparisons between site designs were assessed to identify the possible sources of heavy metals and PAHs. The main contributing source for heavy metals was identified to be from vehicle debris and emissions, while the source of PAHs was identified to be from petrol and diesel engine vehicle emissions. The highest concentration of pollutants was typically found for the 63 micro meter dust samples, proposed to be due to increased surface areas and thus available adsorption sites.

Impact of wildfires and floods on property values: A before and after analysis

One of the most evident casualties of a natural disaster is the property market. The private and social costs from such events run into millions of dollars. In this paper, we use a unique dataset to examine the impact on residential house prices affected by natural disasters using a hedonic property (HP) values approach. For this purpose, we use data before and after a wildfire and floods from Rockhampton in central Queensland, Australia. The data is unique because one suburb was affected by wildfires and another was affected by floods. For the analysis, three suburbs namely Frenchville, Park Avenue and Norman Gardens are used. Frenchville was significantly affected by wildfires in the latter part of 2009 and to a lesser extent in 2012, while Park Avenue was affected by floods at the end of 2010, January 2011–2013. Norman Gardens, which was relatively unaffected, is used as a control site. This enables us to examine the before and after effects on property values in the three suburbs. The results confirm that soon after a natural disaster property prices in affected areas decrease even though the large majority of individual houses remain unaffected. Furthermore, the results indicate that the largely unaffected suburb may gain immediately after a natural disaster but this gain may disappear if natural disasters continue to occur in the area/region due to the stigma created. The results have several important policy decision and welfare implications which are briefly discussed in the paper.

Reverie I

Reverie I is a large-scale public art work commissioned by the Brisbane City Council for permanent installation on the Gardens Point Road Plinth adjacent to QUT Gardens Point campus in Brisbane. The work forms part of the artist's ongoing exploration of the methodology of self-portraiture and amorphous form. In this work, sculpted curls of hair have been assembled according to contours of its constituent cast panels - their capacity to nest with one another determined the final form of the work. The resulting mass of curls resembles both an oversized wig, a withered mulberry and a leaden cloud to invoke notions of movement, reflection and temporality. From the didactic panel: "The curls of Reverie I are derived from 18th century sculptural portraiture. The twisting forms of the highly styled wig known as a periwig were abstracted and inventive, while also bestowing an air of intellectual authority. Curls also evoke two aspects of this particular site: the erratic movement of water associated with the complex tidal movements of Brisbane River, and a state of mental reflection relevant to both the nearby university grounds (where intellectual work takes place) and the riverside pathway (a site for daydreaming)."
