Distinctiveness: islands

Islands are an integral part of how Queensland is imagined, perceived and portrayed. While islands hold a certain universal appeal, the tropical locality and density of islands along the Queensland coast contributes to a distinctive landscape

Personality and religious maturity

A sample of 226 students attending seminaries, theological colleges, and bible schools completed Newton Malony’s Religious Status Inventory (as a measure of religious maturity) alongside the short-form Revised Eysenck Personality Questionnaire. The data demonstrated some ways in which stable toughminded extraverts projected higher levels of religious maturity according to some of Malony’s criteria

Custom, conflict and the construction of heritage: European huts on the Tasmanian central plateau

Since the 1990s, cultural heritage managers have become increasingly interested in the intangible as the way that local communities create value for cultural heritage places. The present paper uses historical and ethnographic information on the practices of people living below the Great Western Tiers in Tasmania to examine the way these people turned the huts on the Central Plateau into heritage. Increased environmental regulation in the late 1980s and early 1990s resulting from the inclusion of the Central Plateau in the Tasmanian Wilderness World Heritage Area disrupted a range of practices that maintained communal attachment to and 'ownership' of the land. Some of the people living below the Great Western Tiers responded by using the huts on the plateau to memorialise their past attachments to the mountain. But this created a new status for huts as heritage, and both the regulator and the regulated agreed that this category of buildings now needed managing. This fundamentally altered the nature of the communal attachment to parts of the Central Plateau because it required an acceptance of the regulatory framework that had disrupted the practices that were the basis of the original 'communal' ownership of land

The effects of retardation on the topological plasmonic chain: plasmonic edge states beyond the quasistatic limit

We study a one-dimensional plasmonic system with non-trivial topology: a chain of metallic nanoparticles with alternating spacing, which is the plasmonic analogue to the Su-Schreiffer-Heeger model. We extend previous efforts by including long range hopping with retardation and radiative damping, which leads to a non-Hermitian Hamiltonian with frequency dependence. We calculate band structures numerically and show that topological features such as quantised Zak phase persist due to chiral symmetry. This predicts parameters leading to topologically protected edge modes, which allows for positioning of disorder-robust hotspots at topological interfaces, opening up novel nanophotonics applications

Stimulation of microglial metabotropic glutamate receptor mGlu2 triggers tumor necrosis factor alpha-induced neurotoxicity in concert with microglial-derived fas ligand

Activated microglia may be detrimental to neuronal survival in a number of neurodegenerative diseases. Thus, strategies that reduce microglial neurotoxicity may have therapeutic benefit. Stimulation of group II metabotropic glutamate (mGlu) receptors on rat primary microglia with the specific group II agonist 2S, 2 ' R, 3 ' R- 2-(2 ', 3 '-dicarboxy-cyclopropyl) glycine for 24 h induced microglial activation and resulted in a neurotoxic microglial phenotype. These effects were attributable to preferential mGlu2 stimulation, because N-acetyl-L-aspartyl-L-glutamate, a specific mGlu3 agonist, did not induce microglial activation or neurotoxicity. Stimulation of microglial mGlu2 but not mGlu3 induced caspase-3 activation in cerebellar granule neurons in culture, using microglial-conditioned media as well as cocultures. Stimulation of microglial mGlu2 induced tumor necrosis factor-alpha(TNF alpha) release, which contributed to microglial neurotoxicity mediated via neuronal TNF receptor 1 and caspase-3 activation. Stimulation of microglial group I or III mGlu receptors did not induce TNF alpha release. TNF alpha was only neurotoxic in the presence of microglia or microglial-conditioned medium. The toxicity of TNF alpha could be prevented by coexposure of neurons to conditioned medium from microglia stimulated by the specific group III agonist L-2-amino-4-phosphono-butyric acid. The neurotoxicity of TNF alpha derived from mGlu2-stimulated microglia was potentiated by microglial-derived Fas ligand (FasL), the death receptor ligand. FasL was constitutively expressed in microglia and shed after mGlu2 stimulation. Our data suggest that selective and inverse modulation of microglial mGlu2 and mGlu3 may prove a therapeutic target in neuroinflammatory diseases such as Alzheimer's disease and multiple sclerosis

The big squeeze: work, home and care in 2012

The Australian Work and Life Index (AWALI) survey measures how work intersects with other life activities, as seen by a randomly selected representative group of 2,887 working Australians.In recent years a number of major events have influenced Australians’ work, personal, family and community lives. The global financial crisis commenced in 2007/8 and international financial markets have experienced continuing instability. The Fair Work Act 2009 introduced a number of changes to the regulation of work. These included a new net of National Employment Standards that incorporated a formal right for some workers to request flexibility or extended unpaid parental leave from 1 January 2010. A national system of paid parental leave came into effect in January 2011. At the same time, the Australian labour force has continued to evolve, with increasing participation of women, declining rates of participation amongst men, an aging workforce and a continuing shift in the composition of employment away from manufacturing and agriculture towards the services sector

Precision teaching and fluency: the effects of charting and goal-setting on skaters’ performance

This research involved three successive studies where precision teaching methods were used to increase roller skaters performance rates of basic skating skills. The first study compared precision teaching methods both with and without the use of charting in a group design, and compared both within-subject and betweensubject differences for 12 skaters. Results showed that charting did not increase performance rates over that seen when charting was not used. The second study was a group design which compared two different types of goals, or performance aims, on skaters‟ performance. No difference was found between the two groups of 5 skaters when one group used a fixed, difficult goal and a second used a flexible, easier goal. In the final study, a single-subject design was used and 8 skaters completed a control condition where no goals were set before a goal was introduced for 4 skaters. It was found that an immediate increase in performance rates occurred following the introduction of the goal. Overall these three studies showed that skaters improved their performance rates over sessions, even in the absence of charting and/or goals, demonstrating that precision teaching can be applied to the sport of roller skating

Merging DNA metabarcoding and ecological network analysis to understand and build resilient terrestrial ecosystems

Summary 1. Significant advances in both mathematical and molecular approaches in ecology offer unprecedented opportunities to describe and understand ecosystem functioning. Ecological networks describe interactions between species, the underlying structure of communities and the function and stability of ecosystems. They provide the ability to assess the robustness of complex ecological communities to species loss, as well as a novel way of guiding restoration. However, empirically quantifying the interactions between entire communities remains a significant challenge. 2. Concomitantly, advances in DNA sequencing technologies are resolving previously intractable questions in functional and taxonomic biodiversity and provide enormous potential to determine hitherto difficult to observe species interactions. Combining DNA metabarcoding approaches with ecological network analysis presents important new opportunities for understanding large-scale ecological and evolutionary processes, as well as providing powerful tools for building ecosystems that are resilient to environmental change. 3. We propose a novel ‘nested tagging’ metabarcoding approach for the rapid construction of large, phylogenetically structured species-interaction networks. Taking tree–insect–parasitoid ecological networks as an illustration, we show how measures of network robustness, constructed using DNA metabarcoding, can be used to determine the consequences of tree species loss within forests, and forest habitat loss within wider landscapes. By determining which species and habitats are important to network integrity, we propose new directions for forest management. 4. Merging metabarcoding with ecological network analysis provides a revolutionary opportunity to construct some of the largest, phylogenetically structured species-interaction networks to date, providing new ways to: (i) monitor biodiversity and ecosystem functioning; (ii) assess the robustness of interacting communities to species loss; and (iii) build ecosystems that are more resilient to environmental change
