Bluebird AR

"What is Bluebird AR? Bluebird AR was the ABC's alternate reality drama set around the leak of Bluebird, a clandestine geoengineering initiative created by eco-billionaire Harrison Wyld. Proposing a fictional scenario set against a backdrop of real world possibilities, Bluebird AR took some of the conventions of the well-established alternate reality game (ARG) genre and pulled them into the relatively new area of online drama, to create a hybrid entertainment form best described as 'participatory drama'. With Bluebird AR's interactive narrative centred on the experimental science of geoengineering, the deliberate manipulation of the Earth's atmosphere to counteract global warming, the events and characters in the Bluebird story were entirely fictional but fused with reality online. Inhabiting a mixture of third party social media spaces and websites created by the ABC, the story incorporated real online articles, scientific journals, media and debate around geoengineering. In an Australian first, ABC Innovation launched Bluebird AR on 27 April 2010, with a 6 week live phase. Audience members were invited to play collectively to help 'unlock the drama' and push forward the emerging narrative, or passively watch the story unfold in real-time across the internet. Bluebird AR subverted ARG conventions with the high quality of its production and assets, and raised the stakes for online drama with its level of audience participation." © 2014 ABC "Introduction One of the most exciting creative challenges of producing Bluebird AR was formulating the broad array of visual styles and treatments required for the project's diverse range of content. Many assets also needed to translate well not only online but across other media, including television and print. With the project's producers keen to create a visually rich narrative with high production values from the outset, inspiration for the production design for various aspects of the Bluebird story began in the earliest pitching phase in September 2008. Particular visual treatments and styles for Bluebird's characters, their web spaces and real world possessions were formulated concurrently with the creation of their profiles. Ideas around how various clues and gameplay spaces might look and feel were also explored at this early stage. Bluebird AR's small but tight creative team produced 7 website designs and brands, motion graphics for title sequences and logo animations, rotoscope animation, 3D compositing and animation, 3D wireframes and schematics, countless Photoshop composites, and a vast array of character assets for the DC (including Kyle's Bluebird Labs security pass and resignation letter, Kruger's American and Russia passports and birth certificate, Harrison's divorce papers, and more)…" © 2014 ABC

Cartels – What are they and how to avoid being part of one : the implications of University fee deregulation

Universities supply a range of services to students. These include most obviously, tuition services in relation to undergraduate and postgraduate courses; research supervision services in relation to research degrees; as well as consultancy services in relation to Government and industry work. For the purposes of the CCA, universities are trading corporations. They engage in trade or commerce through the provision of a range of services for reward. As such Universities are subject to the same rules and regulations that govern the conduct of other trading corporations, such Coles and Woolworths. As senior officers and managers of a trading corporation you need to acquire some basic understanding of the rules that govern competition in the education sector. In other sectors, companies generally undertake a risk assessment of those areas where they are most at risk of contravening the CCA; to ascertain in advance how problems might arise so that they can put in place strategies to mitigate the risk of inadvertent contraventions.

Meta-analysis of microarray data identifies GAS6 expression as an independent predictor of poor survival in ovarian cancer

Seeking new biomarkers for epithelial ovarian cancer, the fifth most common cause of death from all cancers in women and the leading cause of death from gynaecological malignancies, we performed a meta-analysis of three independent studies and compared the results in regard to clinicopathological parameters. This analysis revealed that GAS6 was highly expressed in ovarian cancer and therefore was selected as our candidate of choice. GAS6 encodes a secreted protein involved in physiological processes including cell proliferation, chemotaxis, and cell survival. We performed immunohistochemistry on various ovarian cancer tissues and found that GAS6 expression was elevated in tumour tissue samples compared to healthy control samples (P < 0.0001). In addition, GAS6 expression was also higher in tumours from patients with residual disease compared to those without. Our data propose GAS6 as an independent predictor of poor survival, suggesting GAS6, both on the mRNA and on the protein level, as a potential biomarker for ovarian cancer. In clinical practice, the staining of a tumour biopsy for GAS6 may be useful to assess cancer prognosis and/or to monitor disease progression.

Transplantation of human amnion epithelial cells reduces hepatic fibrosis in immunocompetent CCl4-treated mice

Chronic liver injury and inflammation lead to hepatic fibrosis, cirrhosis, and liver failure. Embryonic and mesenchymal stem cells have been shown to reduce experimental liver fibrosis but have potential limitations, including the formation of dysplastic precursors, tumors, and profibrogenic cells. Other stem-like cells may reduce hepatic inflammation and fibrosis without tumor and profibrogenic cell formation. To test this hypothesis we transplanted human amnion epithelial cells (hAEC), isolated from term delivered placenta, into immunocompetent C57/BL6 mice at week 2 of a 4-week regimen of carbon tetrachloride (CCl4) exposure to induce liver fibrosis. Two weeks following hAEC infusion, intact cells expressing the human-specific markers inner mitochondrial membrane protein and human leukocyte antigen-G were found in mouse liver without evidence of host rejection of the transplanted cells. Human albumin, known to be produced by hAEC, was detected in sera of hAEC-treated mice. Human DNA was detected in mouse liver and also spleen, lungs, and heart of some animals. Following hAEC transplantation, CCl4-treated animals showed decreased serum ALT levels and reduced hepatocyte apoptosis, compared to controls. hAEC-treated mouse liver had lower TNF-α and IL-6 protein levels and higher IL-10 compared to animals given CCl4 alone. Compared to CCl4 controls, hAEC-treated mice showed fewer activated collagen-producing hepatic stellate cells and less fibrosis area and collagen content. Reduced hepatic TGF-β levels in conjunction with a twofold increase in the active form of the collagen-degrading enzyme matrix metalloproteinase-2 in hAEC-treated mice compared to CCl4 controls may account for the reduction in fibrosis. hAEC transplantation into immunocompetent mice leads to cell engraftment, reduced hepatocyte apoptosis, and decreased hepatic inflammation and fibrosis.

Aspect-based opinion extraction from customer reviews

Text is the main method of communicating information in the digital age. Messages, blogs, news articles, reviews, and opinionated information abounds on the Internet. People commonly purchase products online and post their opinions about purchased items. This feedback is displayed publicly to assist others with their purchasing decisions, creating the need for a mechanism with which to extract and summarize useful information for enhancing the decision-making process. Our contribution is to improve the accuracy of extraction by combining different techniques from three major areas, named Data Mining, Natural Language Processing techniques and Ontologies. The proposed framework sequentially mines product’s aspects and users’ opinions, groups representative aspects by similarity, and generates an output summary. This paper focuses on the task of extracting product aspects and users’ opinions by extracting all possible aspects and opinions from reviews using natural language, ontology, and frequent “tag” sets. The proposed framework, when compared with an existing baseline model, yielded promising results.

Sol-gel synthesis and characterization of cubic bismuth zinc niobium oxide nanopowders

Bismuth zinc niobium oxide (BZN) was successfully synthesized by a diol-based sol-gel reaction utilizing metal acetate and alkoxide precursors. Thermal analysis of a liquid suspension of precursors suggests that the majority of organic precursors decompose at temperatures up to 150°C, and organic free powders form above 350°C. The experimental results indicate that a homogeneous gel is obtained at about 200°C and then converts to a mixture of intermediate oxides at 350–400°C. Finally, single-phased BZN powders are obtained between 500 and 900°C. The degree of chemical homogeneity as determined by X-ray diffraction and EDS mapping is consistent throughout the samples. Elemental analysis indicates that the atomic ratio of metals closely matches a Bi1.5ZnNb1.5O7 composition. Crystallite sizes of the BZN powders calculated from the Scherrer equation are about 33–98 nm for the samples prepared at 500–700°C, respectively. The particle and crystallite sizes increase with increased sintering temperature. The estimated band gap of the BZN nanopowders from optical analysis is about 2.60–2.75 eV at 500-600°C. The observed phase formations and measured results in this study were compared with those of previous reports.
