Description:
Text Classification is the task of mapping a document into one or more classes based on the presence or absence of words (or features) in the document. It is intensively being studied and different classification techniques and algorithms have been developed. This thesis focuses on classification of online documents that has become more critical with the development of World Wide Web. The WWW vastly increases the availability of on-line documents in digital format and has highlighted the need to classify them. From this background, we have noted the emergence of “automatic Web Classification”. These mainly concentrate on classifying HTML-like documents into classes or categories by not only using the methods that are inherited from the traditional Text Classification process, but also utilizing the extra information provided only by Web pages. Our work is based on the fact that, Web documents, contain not only ordinary features (words) but also extra information, such as meta-data and hyperlinks that can be used to advantage the classification process. The aim of this research is to study various ways of using the extra information, in particularly, hyperlink information provided by HTML-documents (Web pages). The merit of the approach, developed in this thesis, is its simplicity, compared with existing approaches. We present different approaches of using hyperlink information to improve the effectiveness of web classification. Unlike other work in this area, we will only use the mappings between linked documents and their own class or classes. In this case, we only need to add a few features called linked-class features into the datasets, and then apply classifiers on them for classification. In the numerical experiments we adopted two wellknown Text Classification algorithms, Support Vector Machines and BoosTexter. The results obtained show that classification accuracy can be improved by using mixtures of ordinary and linked-class features. Moreover, out-links usually work better than in-links in classification. We also analyse and discuss the reasons behind this improvement.

"A natural process in examining properties of Banach spaces is to see if a Banach space can be decomposed into simpler Banach spaces; in other words, to see if a Banach space has complemented subspaces. This thesis concentrates on three main aspects of this problem: norm of projections of a Banach space onto its finite dimensional subspaces; a class of Banach spaces, each of which has a large number of infinite dimensional complemented subspaces; and methods of finding Banach spaces which have uncomplemented subspaces, where the subspaces and the quotient spaces are chosen as well-known classical sequence spaces (finding non-trivial twisted sums)." --Abstract.

"Three sampling campaigns were conducted in the Ballarat, Creswick and Maldon areas. The sampling area is part of the Golden Triangle region where significant gold-mining activities took place from the 1850s to the present day. [...] Locations were chosen to evaluate arsenic distribution in soils, surface waters and plants in different environments. Easy access to sampling locations allowed detailed scientific sampling, especially in the seasonality study. The different range of environments such as agricultural, state forest, mining, urban and rural provided an opportunity to compare the concentrations of arsenic and other elements in the study area. The study of the three selected areas combined provided further understanding of possible exposure and pathways through which arsenic can get into the food chain. "The objective of the study is to measure levels of heavy metals/metalloids in soils, water and plants in various environments, identify whether the heavy metals/metalloids are mobile and bioavailable and understand the importance of clays and oxide complexes in the fixation of metals."

Because mobility is associated with rural social decline, this two-phase cross sectional study investigates whether social patterns in small, rural Australian towns are affected by commuting. Quantitative data, which was gathered via a mail-out questionnaire (response = 54 per cent) that was issued to 1,040 occupationally diverse professionals who worked in fourteen towns throughout north-western Victoria, was analysed to determine whether commuting and non-commuting professionals differed significantly in their community involvement. To explain why certain relationships emerged from survey analysis, face-toface interviews were subsequently undertaken with 24 questionnaire respondents. The key finding of this study is that there is a significant relationship between commuting status and the retention of rural professionals. A significantly greater proportion of noncommuters than commuters remain working in the one location for longer than five years. This finding has important implications for the sustainability of rural areas.

The aim of this Australian Research Council Linkage doctoral project with industry partners UnitingCare-Lifeline Ballarat and Lifeline Australia was to investigate whether calls to Lifeline – a generalist telephone counselling and referral service – could be used as valid and reliable social indicators of health. The Lifeline Australia service receives approximately 1,000 calls a day and key details of each call are recorded on its Client Services Management Information System (CSMIS). A number of research questions directed this study: (1) What are the characteristics or attributes of callers to Lifeline?; (2) How do the patterns of calls to Lifeline vary spatially?; and (3) What is the statistical relationship between calls to Lifeline and other measures of community health? This thesis presents a detailed descriptive summary and analysis of Lifeline’s national CSMIS call data (N = 90,128 cases) from 01-04-2003 to 29-06-2003. It explores this and other sources of call data, such as the Telstra Exchange data, for their potential to be used as social indicators. The project created a model of generalist telephone counselling and referral use (MGTCRU). The MGTCRU was used as a theoretical base to a call rate indicator, named the Lifeline Indicator of Social Need (LISN), which reflects the community’s capacity to provide social support to its most socially isolated residents. The LISN was found to have useful attributes and a potential for use as a social indicator of community strength. The call rate indicator showed a statistically significant relationship with the Accessibility/Remoteness Index of Australia, measures of socio-economic disadvantage, and suicide rates. However, the CSMIS database was found to have certain limitations. The thesis presents recommendations for this situation to be addressed. While acknowledging that there are limitations to telephone counselling call data it is clear that these call data can be used to create cost effective, rapid, reliable, and potentially valid social indicators. This thesis has made a number of significant empirical and theoretical contributions to knowledge on telephone counselling and referral. The descriptive summary of the CSMIS data provided in this thesis might be used in innovative ways by social researchers. The LISN could be used on its own or included in other social indices. The MGTCRU provides a theoretical framework for understanding telephone counselling and referral services use and may assist these services to organise their operations and meet the needs of their callers. This project may have particular application to a current upgrade of Lifeline Australia’s telephony and call data systems.

"This thesis investigates the influence of company and executive characteristics on strategic alliance formation (decision to form alliances, alliance type selection and choice of alliance partners) and performance evaluation of alliances, in the Australian tourism industry sector of travel. The significance of forming strategic alliances as a way of achieving 'harambe' is emphasised throughout this thesis. 'Harambe' is a ki-Swahili term meaning "to pull together, or to work together or to pull the same rope together at the same time" in harmony. The idea here is that companies pool their resources together through strategic alliances to be able to achieve their strategic goals and objectives. The research focuses on three travel sub-sectors - travel agencies, tour operators and wholesalers and how these sub-sectors relate with those of transport and accommodation." -

The field of practice addressed by this Portfolio of works is mental health promotion in the context of survival of extreme, organized, armed violence and associated repression. Studies were undertaken in two historical and geo-political settings – Cambodian refugees in Australia post 1979 and Bulgarian post World War II concentration camp survivors after the fall of communism in 1989. The portfolio reports on original image-based research in mental health promotion, using discussions by focus groups composed of genocide and repression survivors. The discourse developed by each group following reflection on a set of photographs from respective conflict periods was used to explore meaning-making within that survivor group.

"The theme explored in relation to the 3 projects (in this report) was the issue of innovation in clinical practice. As shown in the various reports, innovation can occur at a micro level as in Study 1 when aspects of two therapies were combined in an attempt to speed therapy; in Study 2 the innovation was more routine and practical in amalgamating the various practices of different Departments at the Ballarat Health Services into a treatment protocol for the treatment of young patients affected by critical eating disorders, or innovation in a wider sense; in Study 3 the effectiveness of a new treatment centre was researched. Some the ethical practice issues around innovation in clinical practice were examined in the final paper."-- leaf iii.

Description:
The high rates of depression and suicide among older adults have given rise to research which aims to identify factors that protect older people from mental illness. Recently, Bailey and McLaren (2005) developed and tested a model which investigated the relationships between engagement in various leisure activities performed alone or with others, sense of belonging, depression, and suicidal ideation. The present study examined an extended version of the mental health model, incorporating the additional variables of perceived freedom in leisure and physical health status. A sample of Australian males and females (N = 379) aged 65 years and over (M age = 77.23, SD = 7.48) completed the Perceived Freedom in Leisure Questionnaire, the Yale Physical Activity Survey,the Duke Health Profile, the Sense of Belonging Instrument, the Centre for Epidemiological Studies-Depressive Scale, and the Suicide Subscale of the General Health Questionnaire. Results indicated that the model was invariant for gender, and accounted for 56% of the variance in suicidal ideation. The model indicated that physical health had direct relationships with each variable in the model. Perceived freedom in leisure predicted engagement in physical activity, sense of belonging-antecedent, and depression, whereas sense of belonging psychological state predicted depression and suicidal ideation. Results suggest that interventions aimed at improving older adults’ perceptions of freedom and personal choice with regard to their leisure experiences, maintaining optimal health, and increasing opportunities to foster feelings of belonging and relatedness with others, should protect against the development of mental ill health.

"This research investigated whether engineers, graduating from universities more than a decade after the introduction new occupational health and safety (OHS) legislation in Australia, were being equipped with the knowledge and skills to fulfil their professional, legal and moral responsibilities in relation to occupational health and safety. The study focussed on engineering students as future business leaders and designers of working environments. An instrument was designed to examine the ability of OH&S education to affect decision-making and problem solving competence in engineering students and graduates. The study found that engineering graduates in the 1990's were departing [from] their academic institutions with superficial knowledge of occupational health and safety responsibilities and accountability in the workplace. The evaluative tool identified an absence of safety management skills and knowledge within graduate and student engineer groups and an extensive urge to blame and discipline the victim or blame a government regulatory authority. The research found that although occupational health and safety professionals adopt a strategy of a safe work place rather than place emphasis on individual workers the engineers did not adopt the safe place approach and focussed on the person. It is recommended that the evaluative tool or a derivative of it should be used to evaluate the extent to which our community progresses in developing the vital OHS decision-making skills of the people who will manage and design workplaces." --p.ii.

"Improved survival rates for premature infants have resulted in extended hospital stays in neonatal nurseries with consequent challenges for mothers assuming a parental role. Additionally, maternal medical complications associated with surgical birth, and a need to locate themselves in unfamiliar clinical environments, exacerbate women's experiences and transition to a maternal role competes with other roles at this time. For women living in rural and regional areas, who experience premature birth, there is additional hardship due to isolation, distance and limited support services. There has been little research on women's experiences with infants in special care nurseries in regional Australia."--(leaf ii).

Description:
Losses resulting from traumatic injuries and occupational disease are prevalent in the small business sector of Australian industry. Although the true size of the problem is unclear, it is estimated that the losses amount to more than $8 billion annually. The hazard control measures to counter these losses are largely known and are available to small businesses but they are not widely adopted. Regulators and other bodies have employed a range of intervention strategies to influence decision-makers in small businesses but most have focussed on the dissemination of printed materials or broadbased advertising campaigns with limited success......... The research concludes that the listening processes at the heart of social marketing add to the methods already used in the OHS discipline by forcing the marketer to listen to the subjective assessment of risk as perceived by targets as well as to question the evidence base that supports the legitimacy and efficacy of the proposed intervention. The TTM was found to be a useful means of categorising small business decision-maker behaviour and assessing the readiness for change of individuals and therefore the messages that are needed to unfreeze behaviour. The TTM also provides a tool for evaluation of the impact of an intervention.As a result of this research it is suggested that opinion leaders, who are employed within a social marketing model to diffuse information, multiply the effort of those wishing to increase the adoption of an innovation. Thus engagement of opinion leaders by an OHS authority for the communication of risk control messages may be more cost-effective than attempting to visit every workplace within an industry group. Thus, although social marketing is not in the general repertoire of OHS interventions, it appears to be extremely useful as a framework for interventions and, when used in concert with a stages of change model, provides natural lead indicators for evaluating the impact of OHS interventions. Application of social marketing to people who have the responsibility for the health and safety of others was unique.

Description:
The cost of adverse drug reactions to society in the form of deaths, chronic illness, foetal malformation, and many other effects is quite significant. For example, in the United States of America, adverse reactions to prescribed drugs is around the fourth leading cause of death. The reporting of adverse drug reactions is spontaneous and voluntary in Australia. Many methods that have been used for the analysis of adverse drug reaction data, mostly using a statistical approach as a basis for clinical analysis in drug safety surveillance decision support. This thesis examines new approaches that may be used in the analysis of drug safety data. These methods differ significantly from the statistical methods in that they utilize co variability methods of association to define drug-reaction relationships. Co variability algorithms were developed in collaboration with Musa Mammadov to discover drugs associated with adverse reactions and possible drug-drug interactions. This method uses the system organ class (SOC) classification in the Australian Adverse Drug Reaction Advisory Committee (ADRAC) data to stratify reactions. The text categorization algorithm BoosTexter was found to work with the same drug safety data and its performance and modus operandi was compared to our algorithms. These alternative methods were compared to a standard disproportionality analysis methods for signal detection in drug safety data including the Bayesean mulit-item gamma Poisson shrinker (MGPS), which was found to have a problem with similar reaction terms in a report and innocent by-stander drugs. A classification of drug terms was made using the anatomical-therapeutic-chemical classification (ATC) codes. This reduced the number of drug variables from 5081 drug terms to 14 main drug classes. The ATC classification is structured into a hierarchy of five levels. Exploitation of the ATC hierarchy allows the drug safety data to be stratified in such a way as to make them accessible to powerful existing tools. A data mining method that uses association rules, which groups them on the basis of content, was used as a basis for applying the ATC and SOC ontologies to ADRAC data. This allows different views of these associations (even very rare ones). A signal detection method was developed using these association rules, which also incorporates critical reaction terms.
