The continuously rising Internet attacks pose severe challenges to develop an effective Intrusion Detection System (IDS) to detect known and unknown malicious attack. In order to address the problem of detecting known, unknown attacks and identify an attack grouped, the authors provide a new multi stage rules for detecting anomalies in multi-stage rules. The authors used the RIPPER for rule generation, which is capable to create rule sets more quickly and can determine the attack types with smaller numbers of rules. These rules would be efficient to apply for Signature Intrusion Detection System (SIDS) and Anomaly Intrusion Detection System (AIDS).
Institutional Ownership, Audit Committee and Risk Disclosure – Evidence from Australian Stock Market
Resumo:
This study investigates the influence of institutional ownership and audit committees corporate risk disclosures. Focusing on analysing firms’ risk disclosures make in their 2009 annual reports, our sample constitutes a sample of 66 Australian listed firms. We divide institutional shareholders into dedicated-type institutional block shareholders and transient-type institutional block shareholders. We find that while there is no significant relationship between dedicated-type institutional block shareholders and risk disclosure, there is a positive relationship between transient-type institutional block shareholders and risk disclosures. Our result is consistent with a principal that wields limited monitoring resources while achieving high resource dependency over management. We also find a significant and positive relationship between audit committee independence and risk disclosures, showing the positive role played by audit committee in improving the information transparency and reducing information asymmetry in capital market.

The purpose of this project, supported by the Office for Learning and Teaching (formerly the Australian Learning and Teaching Council), is to design and implement a framework that uses a distributed leadership approach for the quality management of Online Learning Environments (OLE) in Australian higher education. The third phase of the research for this project included an online survey of ACODE (Australasian Council on Open, Distance and E-Learning) institutional representatives at Australasian universities conducted during March 2012. A copy of the survey instrument that was employed is included as Appendix 1. The survey included items addressing:
• background/demographic information;
• respondents’ perceptions of importance of, and satisfaction with, elements of the proposed framework;
• respondents’ perceptions of the importance of possible interactions between elements of the proposed framework;
• respondents’ perceptions of the importance and effectiveness of distributed leadership at their universities;
• respondents’ perceptions of the importance, and evidence of presence, of a range of characteristics of distributed leadership at their universities; and
• respondents’ suggested strategies for building and sustaining effective institutional distributed leadership.
A total of 46 current ACODE institutional representatives were publicly identifiable, and were invited to participate in the online survey. Those institutions for which an ACODE representative could be identified are highlighted in Appendix 2. This report presents the results and findings of the survey. In all of the following quantitative analyses, a statistical significance level of p < 0.01 has been adopted. This significance level indicates that the observed result is likely to occur by chance only once for every hundred similar respondent samples, and hence strongly suggests that any observed difference in mean ratings is a real difference.
