One strategy, including resilient areas in marine protected area (MPA) networks, relies on information on the spatial distribution of resilience. We assess the ability to model and map six indicators of coral reef resilience—stress-tolerant coral taxa, coral generic diversity, fish herbivore biomass, fish herbivore functional group richness, density of juvenile corals and the cover of live coral and crustose coralline algae. We use high spatial resolution satellite data to derive environmental predictors and use these in random forest models, with field observations, to predict resilience indicator values at unsampled locations. Predictions are compared with those obtained from universal kriging and from a baseline model. Prediction errors are estimated using cross-validation, and the ability to map each resilience indicator is quantified as the percentage reduction in prediction error compared to the baseline model. Results are most promising (percentage reduction = 18.3%) for mapping the cover of live coral and crustose coralline algae and least promising (percentage reduction = 0%) for coral diversity. Our study has demonstrated one approach to map indicators of coral reef resilience. In the context of MPA network planning, the potential to consider reef resilience in addition to habitat and feature representation in decision-support software now exists, allowing planners to integrate aspects of reef resilience in MPA network development. 2013-05-05T01:45:11Z Knudby, Anders og Jupiter, Stacy og Roelfsema, Chris og Lyons, Mitchell og Phinn, Stuart http://espace.library.uq.edu.au/view/UQ:300041 2013-05-13T14:34:43Z Brinn, M.P. og Carson, K.V. og Esterman, A.J. og Chang, A.B. og Smith, B.J. http://espace.library.uq.edu.au/view/UQ:291540 2013-02-17T00:22:45Z Rahimi-Keshari, Saleh og Caves, Carlton M. og Ralph, Timothy C. http://espace.library.uq.edu.au/view/UQ:293264 2013-03-10T00:30:14Z Branciard, Cyril og Rosset, Denis og Liang, Yeong-Cherng og Gisin, Nicolas http://espace.library.uq.edu.au/view/UQ:290926 2013-02-10T00:50:33Z Rao, Chalapati og Doi, Suhail A. R. http://espace.library.uq.edu.au/view/UQ:288068 Electronic Marketplaces (EMPs) are virtual intermediaries that facilitate exchanges of products between buying and selling organizations. Prior research has examined factors that explain the establishment of EMPs, but scant knowledge exists on how to determine their performance. This study draws on organizational theory to measure EMP performance, thereby utilizing the concept of goals and goal achievement as criteria for success or failure. In this empirical work, we classify EMP as successful or unsuccessful and compare this classification with data collected eight years later. Our research identifies critical EMP goals and promotes the use of goals to determine performance. 2013-01-02T00:00:00Z Matook, Sabine http://espace.library.uq.edu.au/view/UQ:288918 2013-01-11T20:42:43Z Irwan, R. og Huang, H. og Zheng, H. Y. og Wu, H. http://espace.library.uq.edu.au/view/UQ:295009 Although the consumption of alcohol has been part of the collective psyche of Australians since colonization, the overconsumption of alcohol has been, and continues to be, a significant problem for the Australian community. Currently, motivational interviewing (MI) and cognitive behavior therapy (CBT) are seen as the standard psychological interventions for alcohol-use disorders. Despite these approaches demonstrating significant positive effects in the treatment of these difficulties, they are not without limitations. There is therefore a need to continue exploring the application of novel psychotherapeutic developments to the treatment of problematic drinking behaviors. This chapter highlights the potential for metacognitive therapy (MCT) to be an effective alternative approach in the treatment of alcohol-use disorders. Firstly, the history and significance of problematic drinking behaviors in Australia are briefly outlined, and the literature regarding MI and CBT is summarized. A metacognitive conceptual model for alcohol use is outlined and discussed. Two brief case studies are put forward to illustrate the application of MCT for the treatment of alcohol abuse and dependence. From this discussion we propose that the combination ofMI and MCT is a promising new approach that has theoretical underpinnings and could provide positive benefits in the treatment of alcohol-use disorders. 2013-03-27T10:54:21Z Strosl, Esben og Pooctor, Dawn og Kavanagh, David og Beames, Lee http://espace.library.uq.edu.au/view/UQ:300513 2013-05-23T09:39:17Z Guterres, J. og Rossato, L. og Pudmenzky, A. og Doley, D. og Whittaker, M. og Schmidt, S. http://espace.library.uq.edu.au/view/UQ:292647 2013-03-03T01:09:29Z Yan, Pengfei og Mori, Toshiyuki og Wu, Yuanyuan og Li, Zhimin og Auchterlonie, Graeme John og Zou, Jin og Drennan, John http://espace.library.uq.edu.au/view/UQ:275481 2012-06-10T00:00:00Z Liu, Keming og Lu, Deping og Zhou, Haitao og Atrens, A. og Zou, Jin og Yang, Yanling http://espace.library.uq.edu.au/view/UQ:293583 2013-03-14T09:05:57Z Long, Maryann H. og Bogossian, Fiona E. og Johnston, Venerina http://espace.library.uq.edu.au/view/UQ:290621 Small island states are increasingly characterised by the growing role of international migration and remittances as components of national and household incomes. Recent household-level survey data on migration and remittances in two Pacific island states, Fiji and Tonga, demonstrate that where formal social protection systems are largely absent, migration and remittances can perform a similar function informally, contributing significantly to development objectives. Remittances also have a positive effect on poverty alleviation and wealth creation, although the impacts on income distribution are mixed. From a policy perspective, these informal social protection and poverty alleviation mechanisms may be more effective in promoting development than policies designed to incorporate remittances into the formal financial systems. Migration and remittances play an increasingly valuable role in small states where domestic development opportunities are limited. 2013-02-07T12:18:59Z Brown, Richard P.

A disturbed zone or microdamage criterion was proposed and used in the modelling analysis. It combined a lattice bond contact tensile failure criteria and a simple peak particle velocity based approach. Estimates were made of the extent of fracturing, disturbed and interaction zones from fully confined blastholes spaced at distances of up to 18 m, simultaneously initiated with primers positioned every 8 m. Continuous interaction was evident along the explosive column at spacings of ,15 m. When blastholes were spaced at 18 m, the attenuation of the stress wave showed only partial or limited interaction along the column. With regards to the influence of in situ stress magnitudes in the range of 500–1500 m, modelling results appeared to capture the impact of stress intensity on the final extension of the macrofracturing zone. At depths of 1200 m and above, the degree of continuous interaction was diminished at the level of the initiating primers. For the simulated geotechnical conditions, the orientation of radial fractures with respect to the principal stress direction is more evident at anisotropy ratios greater than two. However, the extent and shape of the disturbed zone does not appear to be influenced by anisotropy, which showed a deficiency in the implementation of in situ stresses in the current modelling framework and further work is being conducted to address this limitation. 2013-04-10T11:11:50Z Onederra, I. og Catalan, A. og Chitombo, G. http://espace.library.uq.edu.au/view/UQ:294907 Over the years there have been several attempts to model the explosive rock interaction problem both empirically and numerically. Efforts have mainly focussed on our ability to estimate the extent of damage induced by an explosive charge beyond an excavation boundary such as a final pit wall or beyond a tunnel or stope perimeter. This paper describes the latest developments of the Hybrid Stress Blasting Model (HSBM) and demonstrates the ability of the code to predict the three dimensional extent and shape of the damage zone from fully coupled explosive charges. Data obtained from controlled experiments and modelling results reported in this paper indicate that the zone of damage can be influenced by the points of initiation of the explosive charge, its length and proximity to free face boundaries. Simple simulations of the potential damage envelopes from large diameter blastholes applying single and dual priming initiation are performed. The simulations included both confined and unconfined free faced conditions. Results show that the three dimensional damage envelopes are influenced by the direction of propagation and subsequent interaction of stress waves between initiation points. For example, the extent of surface damage from single toe initiation extends further behind the blasthole and this can be explained by a stress propagation broadening effect due to the close impedance matching between the explosive andthe simulated rock mass. Under similar conditions, when a mid and toe primer are fired simultaneously, the charge is dynamically split and the interaction between the two shorter detonation fronts causes an increase in the damage zone between these two primers. Further work is required to fully quantify the degree of damage within the predicted envelopes, in particular with regards to potential impacts on intact rock material properties, existing is continuities and overall weakening effects of the rock mass. 2013-03-26T13:14:52Z Onederra, I og Furtney, J.

Safety issues related to administering these complex mixtures, however, prevent their universal application. Through identification of the microbial components responsible for protective immunity, vaccine formulations can be simplified, enabling molecular-level vaccine characterization, improved safety profiles, prospects to develop new high-priority vaccines (e.g. for HIV, tuberculosis, and malaria), and the opportunity for extensive vaccine component optimization. This subunit approach, however, comes at the expense of decreased immunity, requiring the addition of immunostimulatory agents (adjuvants). As few adjuvants are currently used in licensed vaccines, adjuvant development represents an exciting area for medicinal chemists to play a role in the future of vaccine development. In addition, immune responses can be further customized though optimization of delivery systems, tuning the size of particulate vaccines, targeting specific cells of the immune system (e.g. dendritic cells), and adding components to aid vaccine efficacy in whole immunized populations (e.g. promiscuous T-helper epitopes). Herein we review the current state of the art and future direction in subunit vaccine development, with a focus on the described components and their potential to steer the immune response toward a desired response. The subunit approach: Despite their excellent track record, traditional vaccine approaches have failed for several high priority diseases. Subunit vaccines offer hope for new, safer, highly characterized vaccines. Herein we discuss key components for next-generation subunit vaccine development. 2013-03-24T00:04:09Z Moyle, Peter Michael og Toth, Istvan http://espace.library.uq.edu.au/view/UQ:284763 We present a striking case of phenotypic convergence within the speciose and taxonomically unstable Hydrophis group of viviparous sea snakes. Enhydrina schistosa, the ‘beaked sea snake’, is abundant in coastal and inshore habitats throughout the Asian and Australian regions, where it is responsible for the large majority of recorded deaths and injuries from sea snake bites. Analyses of five independent mitochondrial and nuclear loci for populations spanning Australia, Indonesia and Sri Lanka reveal that this ‘species’ actually consists of two distinct lineages in Asia and Australia that are not closest relatives. As a result, Australian ‘‘E. schistosa’’ are elevated to species status and provisionally referred to Enhydrina zweifeli. Convergence in the characteristic ‘beaked’ morphology of these species is probably associated with the wide gape required to accommodate their spiny prey. Our findings have important implications for snake bite management in light of the medical importance of beaked sea snakes and the fact that the only sea snake anti-venom available is raised against Malaysian E. schistosa. 2012-11-13T12:56:39Z Ukuwela, Kanishka D.

The recent past has seen multiple clinical studies attempting to document whether limiting the perioperative use of morphine is beneficial for cancer surgery patients. Furthermore, a lot of exciting new data has been generated in vitro, but also in preclinical and clinical studies, that indirectly shed light on the effect of opioids on cancer. Future directions in the field may include the role of endogenous morphine in tumour biology, the recent discovery that genetic polymorphisms of the mu opioid receptor are associated with cancer survival, the role of microRNAs in opioid receptor regulation and signalling, and the potential usefulness of peripheral opioid antagonists. 2012-09-20T16:16:38Z Parat, Marie-Odile http://espace.library.uq.edu.au/view/UQ:300132 Moyamoya disease is a rare cerebrovascular occlusive disorder characterized by stenosis in the circle of Willis with the development of a compensatory circulation. It has been associated with significant morbidity in pregnancy including intracranial haemorrhage, ischaemic stroke and epilepsy. We present the case of a 26-year-old woman with a previous diagnosis of moyamoya vasculopathy with bilateral superficial temporal to middle cerebral artery bypass grafting. During the second trimester, she developed significant neurological symptoms related to postural hypotension in the presence of a stenosis of the right-sided graft. The hypotension was treated with fludrocortisone therapy with improvement in blood pressure and symptoms. Moyamoya vasculopathy poses unique challenges to obstetric care. This is the first report of use of fludrocortisone for maintenance of blood pressure during pregnancy in this condition. 2013-05-14T15:23:46Z Barrett, Helen L. og Lust, Karin og Fagermo, Narelle og Callaway, Leonie K. og Minuzzo, Lee http://espace.library.uq.edu.au/view/UQ:298533 2013-04-28T00:09:59Z Moore, Ryka og Kyd, Jennelle M. og Carzino, Rosemary og Armstrong, David og Grimwood, Keith og Otczyk, Diana C. og Cripps, Allan W. http://espace.library.uq.edu.au/view/UQ:282298 2012-09-22T00:00:00Z Hartel, Charmine E.

Here we demonstrate three-photon quantum operation of an integrated device containing three coupled interferometers, eight spatial modes and many classical and nonclassical interferences. This represents a critical advance over previous complexities and the first on-chip nonclassical interference with more than two photonic inputs. We introduce a new scheme to verify quantum behaviour, using classically characterised device elements and hierarchies of photon correlation functions. We accurately predict the device’s quantum behaviour and show operation inconsistent with both classical and bi-separable quantum models. Such methods for verifying multiphoton quantum behaviour are vital for achieving increased circuit complexity. Our experiment paves the way for the next generation of integrated photonic quantum simulation and computing devices. 2013-04-28T00:34:20Z Metcalf, Benjamin J. og Thomas-Peter, Nicholas og Spring, Justin B. og Kundys, Dmytro og Broome, Matthew A. og Humphreys, Peter C. og Jin, Xian-Min og Barbieri, Marco og Kolthammer, W.

J. http://espace.library.uq.edu.au/view/UQ:290287 Thanks to advances in next-generation technologies, genome sequences are now being generated at breadth (e.g. across environments) and depth (thousands of closely related strains, individuals or samples) unimaginable only a few years ago. Phylogenomics ? the study of evolutionary relationships based on comparative analysis of genome-scale data ? has so far been developed as industrial-scale molecular phylogenetics, proceeding in the two classical steps: multiple alignment of homologous sequences, followed by inference of a tree (or multiple trees). However, the algorithms typically employed for these steps scale poorly with number of sequences, such that for an increasing number of problems, high-quality phylogenomic analysis is (or soon will be) computationally infeasible. Moreover, next-generation data are often incomplete and error-prone, and analysis may be further complicated by genome rearrangement, gene fusion and deletion, lateral genetic transfer, and transcript variation. Here we argue that next-generation data require next-generation phylogenomics, including so-called alignment-free approaches. 2013-02-01T07:59:16Z Chan, Cheong Xin og Ragan, Mark A. http://espace.library.uq.edu.au/view/UQ:253675 The potential benefits of nicotine in the prevention of ulcerative colitis are discussed.
