Athletes series

The researcher was invited to photograph athletes in the lead-up to the 2006 Commonwealth Games held in Melbourne. She photographed four indigenous athletes, to produce a series of four large-scale cotton rag prints, 1 meter x 1 meter, printed onto photorag paper from digital files. “My photographic practice can be described as both political and spiritual, in the sense that as an Aboriginal Indigenous artist I take stock of the rationalising effect of the technologies I use, and create work that evokes nature and spirit. My methods often involve re-photographing or digitally re-working landscape photographs and adding historical or cultural icons of significance. Working with Indigenous athletes has been an honour and a pleasure. I admire the athletes’ passion and dedication to their chosen sport, and above all their humility, which seems a trait somewhat in contrast to what it takes to attain the highest levels of achievement. Indigenous athletes are wonderful role models for all Australians, and in making creative work that places their luminary presence with the land, I am aligning sportspeople with a deep sense of nature and spirit.” – Leah King-Smith. These works were commissioned by the National Portrait Gallery for the exhibition FLASH: Australian Athletes in Focus. The exhibition was a significant element in Melbourne2006 Festival, the cultural festival of the Commonwealth Games. The exhibition was prominently reviewed in Portrait: Magazine of Australian and International Portraiture and was subsequently remounted at Old Parliament House, Canberra (15 July to 12 November, 2006). One image was used for the front cover of Art Monthly, (March 2006).

Dancelines series

Dancelines was a body of work commissioned by Bangarra Dance Company and The Arts Centre, Melbourne. The artist was invited to produce a body of work that responded to the dance company's production of 'Boomerang'. The result was a body of photographs that applied the artist's interest in layering as a photographic technique and her interest in indigenous subjectivity and sprituality. The works drew correspondences between Rheannan Port, the subject's, own biography and character and the artist's voluminous archive of iamges of the natural world. The result complemented and formalised the collaborative processes that the artist had previously only explored in the video medium. The work was shown at the George Adams Gallery of the Arts Centre as part of Melbourne 2006 Commonwealth Games Arts Festival. 'Rheannan Port, #1' was selected for the 2006 Archibald Photographic Portrait Prize, at the Art Gallery of New South Wales. The work was reviewed in The Age newspaper.

No evidence for subliminal affective priming with emotional facial expression primes

The present study investigated whether facial expressions of emotion presented outside consciousness awareness will elicit evaluative responses as assessed in affective priming. Participants were asked to evaluate pleasant and unpleasant target words that were preceded by masked or unmasked schematic (Experiment 1) or photographic faces (Experiments 1 and 2) with happy or angry expressions. They were either required to perform the target evaluation only or to perform the target evaluation and to name the emotion expressed by the face prime. Prime-target interval was 300 ms in Experiment 1 and 80 ms in Experiment 2. Naming performance confirmed the effectiveness of the masking procedure. Affective priming was evident after unmasked primes in tasks that required naming of the facial expressions for schematic and photographic faces and after unmasked primes in tasks that did not require naming for photographic faces. No affective priming was found after masked primes. The present study failed to provide evidence for affective priming with masked face primes, however, it indicates that voluntary attention to the primes enhances affective priming.

Numerical Modelling of LiteSteel Beams Subject to Shear

Abstract: LiteSteel beam (LSB) is a new cold-formed steel hollow flange channel beam produced using a patented manufacturing process involving simultaneous cold-forming and dual electric resistance welding. It has the beneficial characteristics of torsionally rigid closed rectangular flanges combined with economical fabrication processes from a single strip of high strength steel. Although the LSB sections are commonly used as flexural members, no research has been undertaken on the shear behaviour of LSBs. Therefore experimental and numerical studies were undertaken to investigate the shear behaviour and strength of LSBs. In this research finite element models of LSBs were developed to investigate their nonlinear shear behaviour including their buckling characteristics and ultimate shear strength. They were validated by comparing their results with available experimental results. The models provided full details of the shear buckling and strength characteristics of LSBs, and showed the presence of considerable improvements to web shear buckling in LSBs and associated post-buckling strength. This paper presents the details of the finite element models of LSBs and the results. Both finite element analysis and experimental results showed that the current design rules in cold-formed steel codes are very conservative for the shear design of LSBs. The ultimate shear capacities from finite element analyses confirmed the accuracy of proposed shear strength equations for LSBs based on the North American specification and DSM design equations. Developed finite element models were used to investigate the reduction to shear capacity of LSBs when full height web side plates were not used or when only one web side plate was used, and these results are also presented in this paper.
