    Victor Wong studied human acquisition learning over multiple contexts using virtual reality. He found that learning an association over multiple contexts can impact subsequent extinction training. This suggests that fears acquired over multiple contexts may be more difficult to treat using exposure-based therapies and will need to be augmented for effectiveness

    Grimoires: Grid Registry with Metadata Oriented Interface: Robustness, Efficiency, Security --- Work-in-Progress

    No full text
    Grid registries allow users to discover resources made available by Grid resource providers. In this paper, we present our on-going work on a next-generation registry, initially designed as part of the myGrid project and to be part of the OMII Grid software release. Specifically, we discuss the support of semantic service descriptions and task/user-specific metadata, along with related performance and security considerations

    The stock market plays a major role in the entire financial market. How to obtain effective trading signals in the stock market is a topic that stock market has long been discussing. This paper first reviews the Deep Reinforcement Learning theory and model, validates the validity of the model through empirical data, and compares the benefits of the three classical Deep Reinforcement Learning models. From the perspective of the automated stock market investment transaction decision-making mechanism, Deep Reinforcement Learning model has made a useful reference for the construction of investor automation investment model, the construction of stock market investment strategy, the application of artificial intelligence in the field of financial investment and the improvement of investor strategy yield

    This paper examines diversification benefits of Socially Responsible Investment (SRI) in a portfolio context. SRIs have been documented with lower volatility, while not sacrificing returns as compared to mainstream shares. Two portfolios are formed from Australian investors' perspective using daily data from 1994 to 2012 and are compared against each other; one portfolio consisting of SRI with mainstream shares and bonds and another without SRI. Our results confirm the benefits of SRI in a portfolio with a higher efficient frontier and the SRI portfolio obtained higher risk-adjusted return with lower value-at-risk. The findings are useful to SRI investors and fund managers who have interest in diversifying their portfolios into SRI. Keywords: socially responsible investments, portfolio, Australian perspectiv
