An Examination of Australians of Hellenic Descent in the State Parliament of Victoria
Continuing a series of analyses of the role of elected State and Federal representatives of Hellenic descent in Australia, this paper will focus on the Victorian State Parliament, but with reference also to current and former Victorian Federal parliamentarians
Dentistry
The specialty of Dental Surgery has progressed from the "blood and acrylic" of the early seventies. Dentistry has undergone a quantum leap over the past twenty-five years, with improvements in both technique and technology, bringing us the sophisticated procedures used in today's practice.peer-reviewe
Gravity Duals of Lifshitz-like Fixed Points
We find candidate macroscopic gravity duals for scale-invariant but
non-Lorentz invariant fixed points, which do not have particle number as a
conserved quantity. We compute two-point correlation functions which exhibit
novel behavior relative to their AdS counterparts, and find holographic
renormalization group flows to conformal field theories. Our theories are
characterized by a dynamical critical exponent , which governs the
anisotropy between spatial and temporal scaling , ; we focus on the case with . Such theories describe
multicritical points in certain magnetic materials and liquid crystals, and
have been shown to arise at quantum critical points in toy models of the
cuprate superconductors. This work can be considered a small step towards
making useful dual descriptions of such critical points.Comment: 17 pages, harvmac; v2 comments about behavior of metric near r=0

Multipoint, high time resolution galactic cosmic ray observations associated with two interplanetary coronal mass ejections
[1] Galactic cosmic rays (GCRs) play an important role in our understanding of the interplanetary medium (IPM). The causes of their short timescale variations, however, remain largely unexplored. In this paper, we compare high time resolution, multipoint space-based GCR data to explore structures in the IPM that cause these variations. To ensure that features we see in these data actually relate to conditions in the IPM, we look for correlations between the GCR time series from two instruments onboard the Polar and INTEGRAL (International Gamma Ray Astrophysical Laboratory) satellites, respectively inside and outside Earth\u27s magnetosphere. We analyze the period of 18–24 August 2006 during which two interplanetary coronal mass ejections (ICMEs) passed Earth and produced a Forbush decrease (Fd) in the GCR flux. We find two periods, for a total of 10 h, of clear correlation between small-scale variations in the two GCR time series during these 7 days, thus demonstrating that such variations are observable using space-based instruments. The first period of correlation lasted 6 h and began 2 h before the shock of the first ICME passed the two spacecraft. The second period occurred during the initial decrease of the Fd, an event that did not conform to the typical one- or two-step classification of Fds. We propose that two planar magnetic structures preceding the first ICME played a role in both periods: one structure in driving the first correlation and the other in initiating the Fd
Developing a gender-based approach to chronic conditions and women's health: A qualitative investigation of communitydwelling women and service provider perspectives
© 2015 DiGiacomo et al. Background: Chronic conditions contribute to over 70 % of Australia's total disease burden, and this is set to increase to 80 % by 2020. Women's greater longevity means that they are more likely than men to live with disability and have unique health concerns related to their gender based roles in society. Cultural and social issues can impact on women's health and are important to consider in health services planning and research. In this study, we aimed to identify barriers and facilitators to providing a gender-based approach to chronic conditions and women's health in an eastern metropolitan region of Australia. Methods: Focus groups were used to engage both community-dwelling women who had chronic conditions and relevant professional stakeholders in the target area. Recorded proceedings underwent thematic analysis. Results: Five focus groups were conducted with professional stakeholders and women community members in February and March 2014. Resultant themes included: women's disempowerment through interactions with health systems; social and economic constraints and caregiving roles act to exclude women from participating in self-care and society; and empowerment can be achieved through integrated models of care that facilitate voice and enable communication and engagement. Conclusions: This study underscores the importance of including perspectives of sex and gender in health care services planning. Tailoring services to socio-demographic and cultural groups is critical in promoting access to health care services. Unique epidemiological trends, particularly the ageing of women and new migrant groups, require particular attention
The effect of age on relational encoding as revealed by hippocampal functional connectivity
The neural processes mediating cognition occur in networks distributed throughout the brain. The encoding and retrieval of relational memories, memories for multiple items or multifeatural events, is supported by a network of brain regions, particularly the hippocampus. The hippocampal coupling hypothesis suggests that the hippocampus is functionally connected with the default mode network (DMN) during retrieval, but during encoding, decouples from the DMN. Based on prior research suggesting that older adults are less able to modulate between brain network states, we tested the hypothesis that older adults’ hippocampus would show functional connectivity with the DMN during relational encoding. The results suggest that, while the hippocampus is functionally connected to some regions of the DMN during relational encoding in both younger and older adults, older adults show additional DMN connectivity. Such age-related changes in network modulation appear not to be mediated by compensatory processes, but rather to reflect a form of neural inefficiency, most likely due to reduced inhibition

De novo design of bioactive protein switches.
Allosteric regulation of protein function is widespread in biology, but is challenging for de novo protein design as it requires the explicit design of multiple states with comparable free energies. Here we explore the possibility of designing switchable protein systems de novo, through the modulation of competing inter- and intramolecular interactions. We design a static, five-helix 'cage' with a single interface that can interact either intramolecularly with a terminal 'latch' helix or intermolecularly with a peptide 'key'. Encoded on the latch are functional motifs for binding, degradation or nuclear export that function only when the key displaces the latch from the cage. We describe orthogonal cage-key systems that function in vitro, in yeast and in mammalian cells with up to 40-fold activation of function by key. The ability to design switchable protein functions that are controlled by induced conformational change is a milestone for de novo protein design, and opens up new avenues for synthetic biology and cell engineering
