Personal Exposure Of Children To Formaldehyde In Perth, Western Australia, Victoria S. Lazenby Jan 2010

Personal Exposure Of Children To Formaldehyde In Perth, Western Australia, Victoria S. Lazenby

Theses: Doctorates and Masters

Formaldehyde is a common air pollutant that tends to be found in elevated concentrations in indoor air. Exposure to formaldehyde has the potential to impact on respiratory health, particularly amongst sensitive individuals and populations, including children. Children spend most of their time indoors at home, however, there are very little data on the contribution of formaldehyde concentrations in homes to personal exposure in children. The principal aim of this cross sectional study was to investigate whether the domestic environment is the most significant source of personal exposure of formaldehyde in children. Forty-one primary school children (aged between 8 and 12) …


Analysis Avoidance Techniques Of Malicious Software, Murray Brand Jan 2010

Analysis Avoidance Techniques Of Malicious Software, Murray Brand

Theses: Doctorates and Masters

Anti Virus (AV) software generally employs signature matching and heuristics to detect the presence of malicious software (malware). The generation of signatures and determination of heuristics is dependent upon an AV analyst having successfully determined the nature of the malware, not only for recognition purposes, but also for the determination of infected files and startup mechanisms that need to be removed as part of the disinfection process. If a specimen of malware has not been previously extensively analyzed, it is unlikely to be detected by AV software. In addition, malware is becoming increasingly profit driven and more likely to incorporate …


Impact Of Higher Education Workplace Relations Requirements On Nteu Membership Density, Tulsi Laxman Panchani Jan 2010

Impact Of Higher Education Workplace Relations Requirements On Nteu Membership Density, Tulsi Laxman Panchani

Theses : Honours

The National Tertiary Education Union (NTEU) is the only union working entirely in tertiary education around Australia. The union has over twenty four thousand members comprising of academic and general staff. NTEU maintains membership records at three levels, national, state and branch. The information collected includes gender, age group, employment type and work classification. In late April 2005, Higher Education Workplace Relations Requirements (HEWRRs) legislation was introduced by the Australian government. This legislation imposed restrictions on the interaction between the universities and the union and also curtailed an automatic involvement of the union in the resolution of workplace issues. The …


Where New Meanings Spring: The Relationship Between Indigenous Cultural Meanings For Freshwater Springs And Management Practices: Analysis Of Stories From Kalbarri, Western Australia, Tamara Lee Murdock Jan 2010

Where New Meanings Spring: The Relationship Between Indigenous Cultural Meanings For Freshwater Springs And Management Practices: Analysis Of Stories From Kalbarri, Western Australia, Tamara Lee Murdock

Theses : Honours

While Indigenous peoples' practices have been acknowledged to change and evolve, whether Indigenous cultural meanings invested in a specific place also change and/or evolve over time, and the affect these changes may have on land and water practices has generally been ignored. This study explores the relationship between Indigenous cultural meanings and land and water stewardship practices, and whether these change over time. A qualitative research design was employed in this study to emphasise the complex and dynamic nature of language and the relationship between people, culture and nature. This study utilised interviews collected from traditional Indigenous people concerning stories …


Remote Access Forensics For Vnc And Rdp On Windows Platform, Paresh Kerai Jan 2010

Remote Access Forensics For Vnc And Rdp On Windows Platform, Paresh Kerai

Theses : Honours

There has been a greater implementation of remote access technologies in recent years. Many organisations are adapting remote technologies such as Virtual Network Computing (VNC) and remote desktop (RDP) applications as customer support application. They use these applications to remotely configure computers and solve computer and network issues of the client on spot. Therefore, the system administrator or the desktop technician does not have to sit on the client computer physically to solve a computer issue. This increase in adaptation of remote applications is of interest to forensic investigators; this is because illegal activities can be performed over the connection. …


Website Accessibility Issues In Western Australian Public Libraries, Vivienne L. Conway Jan 2010

Website Accessibility Issues In Western Australian Public Libraries, Vivienne L. Conway

Theses : Honours

Website accessibility is a very real and pressing issue for public libraries internationally. Tim Berners-Lee credited with founding the Web, states "The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect." (Henry & McGee, 2010). There is wide-spread support for adherence to the Web Content Advisory Guidelines Version 1.0 and 2.0 (WCAG) throughout Federal, State and Local levels of government in Australia. The Guidelines have also been affirmed by the Australian Human Rights Commission, disability advocacy groups such as Vision Australia, and the Australian Library and Information Association. The Australian Government …


Theory Of Entropic Security Decay: The Gradual Degradation In Effectiveness Of Commissioned Security Systems, Michael P. Coole Jan 2010

Theory Of Entropic Security Decay: The Gradual Degradation In Effectiveness Of Commissioned Security Systems, Michael P. Coole

Theses: Doctorates and Masters

As a quantitative auditing tool for Physical Protection Systems (PPS) the Estimated Adversary Sequence Interruption (EASI) model has been available for many years. Nevertheless, once a systems macro-state measure has been commissioned (Pi) against its defined threat using EASI, there must be a means of articulating its continued efficacy (steady state) or its degradation over time. The purpose of this multi-phase study was to develop the concept and define the term entropic security decay. Phase one presented documentary benchmarks for security decay. This phase was broken into three stages; stage one presented General Systems Theory (GST) as a systems benchmark …


Comparison And Application Of Three Decorrelation Methods Pca, Maf And Acdc, Jacqueline Ferreira Jan 2010

Comparison And Application Of Three Decorrelation Methods Pca, Maf And Acdc, Jacqueline Ferreira

Theses : Honours

Geostatistics is a branch of applied mathematics that deals with spatially correlated data. Analysing and modelling spatially correlated data can be difficult and time consuming, especially for a multivariate data set. One of the techniques used to make analysis and modelling easier involves decorrelation, whereby a linear transformation on the sample variables is used to associate the spatially correlated variables with a set of decorrelated factors which are statistically and spatially independent. PCA was one of the first multivariate techniques and is mostly used as a data reduction technique. A popular alternative decorrelation technique often used in the mining industry …

The Identification, Development And Application Of Information Culture In The Western Australian Public Sector, Janine Douglas

Theses: Doctorates and Masters

Information can be found in government departments in many forms. It exists, for example, as performance indicators, statistics, economic analysis, policy advice, political know-how or opinions. Using information is a daily and oft repeated activity in government departments. Information is central to the achievement of outcomes and the delivery of services. It is critical to the government’s success in the information economy. It is central to the development of products and services. It supports policy making and it underpins accountability. Government departments are built on the generation and use of information that is relevant to the largest of all customer …
