Real-time functional magnetic resonance imaging can be used to feed back signal changes from the brain to participants such that they can train to modulate activation levels in specific brain areas. Here we present the first study combining up-regulation of brain areas for positive emotions with psychometric measures to assess the effect of successful(More)
The effectiveness of the potent antifungal drug fluconazole is being compromised by the rise of drug-resistant fungal pathogens. While inhibition of Hsp90 or calcineurin can reverse drug resistance in Candida, such inhibitors also impair the homologous human host protein and fungal-selective chemosensitizers remain rare. The MLPCN library was screened to(More)
Despite being a charismatic and well-known species, the social system of the koala (Phascolarctos cinereus--the only extant member of the family Phascolarctidae) is poorly known and much of the koala's sociality and mating behaviors remain un-quantified. We evaluated these using proximity logging-GPS enabled tracking collars on wild koalas and discuss their(More)

Set up the training courses for the different tools and systems such as Mechanical and Electrical CAD/CAM. I developed the concepts and strategies of collaborative engineering for use in the company's long term product development strategies by researching and interviewing client companies engaged in the design of mechanical products using distributed(More)
Pupillometry, the measurement of pupil size, is a technique used widely in psychological research to infer arousal, cognitive effort and processing load in various observer settings. Specifically, pupil dilation has been linked to increased effort in extended visual search (Porter, Troscianko & Gilchrist, 2007) and with the detection of targets in rapid(More)
Prey species that congregate gain protection against predatory attacks and this advantage is often reflected by a reduction in vigilance behaviour by individuals in larger groups. Comparatively few studies have investigated vigilance in solitary animals, but those that have, found that vigilance increases as group size increases because of the threat posed(More)
 This paper describes Engineering Internships, an innovative approach to work based education developed in the Faculty of Engineering at the University of Technology, Sydney (UTS). Each of the two Engineering Internships which students in the UTS program undertake comprises: a preparatory academic subject; a six month period of engineering experience; and(More)
