Recent evidence in the road safety research literature indicates that skills in hazard perception, visual search and attention may be developing executive functions in young novice drivers before the age of 25 years, contributing to their unintentional risk taking behaviour and subsequent high crash rates. The present research aimed to investigate these skills, whether they are predictive of each other, and whether hazard perception can be improved through road commentary training. Twenty-two young novice drivers and eight experienced drivers were recruited as participants in this study. The experienced drivers performed significantly better than the novice drivers on the hazard detection task that was specifically designed for the study. Their visual search skills were also examined and compared using the Visual Search and Attention Test, with the experienced drivers performing significantly better than the novice drivers. Interestingly, a significant positive correlation was found between the scores of the participants on the hazard detection task and the Visual Search and Attention Test which may indicate that the hazard detection skills can be predicted. The novice driver group who received 12 trials of video based road commentary training significantly improved in their hazard detection skills, suggesting that video based road commentary could be an effective road safety intervention for young novice drivers and if developed into a more comprehensive programme, holds promise for future implementation into the New Zealand Graduated Driver Licensing System. The results also hold promise for future investigation into the use of the Visual Search and Attention Test as a predictor of hazard perception skills in novice drivers.

Young people in the Western world demonstrate that they have little connection to democratic processes through their increasing absence from the polls at election time. This trend is evidenced in New Zealand where the secondary school curriculum has little content concerning electoral and political processes. Low voter turn-out is particularly prevalent in the triennial local body elections where only a small proportion of all eligible voters participate.This research is based within two North Shore City secondary schools and has two objectives. The first to establish the current understanding of Year 13 students of the local authority, its activities, governance and decision-making processes and the second to assess the effect of this information on the election activity of the participants. Following the provision of this information to the selected classes and after 2004 local authority elections, the same classes completed questionnaires to ascertain whether their participation (voting and non-voting) in the elections was affected by this intervention. A post-election focus group of non-school-based newly eligible voters enabled some qualitative inquiry into rationale and attitudes.The findings indicate a wide degree of ignorance and reinforce the current political situation where young people see no relevance to them of local authority politics. The research highlights the need to engage young people in civic matters and increase their ownership of and involvement in the democratic process.

Aboriginal young people are exposed to the impact of colonisation in Australia. They are at risk of becoming alienated from their homelands, cultures, communities and families. Some have become alienated, joining one of the most marginalised groups in Australian society – homeless people. Aboriginal young people, many of whom are already marginalised because of their indigeneity, join a group that can be described as further marginalised – that is, Aboriginal and homeless. In essence, Aboriginal homelessness can be seen and described as a loss of sovereignty. The Hebersham Aboriginal Youth Service (HAYS) is an organisation that is responding to the phenomenon of Aboriginal youth homelessness. HAYS is funded and operates under a joint Australian Federal, State and Territory government programmatic response that assists people who are homeless or at risk of becoming homeless. This thesis reviews the design and development of HAYS as an Aboriginal service organisation. The central thesis research question is: How should a service for homeless Aboriginal youth be designed and developed? In addressing this question, a case study methodology is utilised which is capable of facilitating research in contemporary organisational settings, such as in HAYS where its design participants operate around specific visions and goals. The research findings indicate that HAYS should become a ‘modern-day tribal ground’ in the form of the Mount Druitt Aboriginal Homeland Centre (MDAHC). In order to progress this model, a substantive theory of coherent dialogue is presented containing five critical design and development propositions educed from the research. The theory contains lessons for the design and development of urban Aboriginal community service organisations. This thesis concludes with a plea for consciousness-raising between Aboriginal and non-Aboriginal people involved in the design and development of Aboriginal community service organisations – a move towards the development of a critical consciousness for a better world through coherent dialogue. / Doctor of Philosophy (PhD)

Health-Related Quality of Life (HRQOL) is an important outcomes measure in cancer and there are specific issues depending on the site, stage, treatment and patient age. Although numerous instruments are available for cancer HRQOL, most are designed for adults, some for children, but none for adolescents and young adults (AYA) who have special age-specific concerns and poor improvement in survival compared with other age groups. An existing HRQOL instrument was modified to ensure its suitability for AYA, its validity, reliability and sensitivity were tested in Australians aged 16 to 25 years old diagnosed with cancer or a blood disorder. Varni’s PedsQLTM Measurement Model (13-18 year olds) was selected, modified then administered to families recruited from haematology/oncology clinics and wards at three Sydney Metropolitan Hospitals in person or by telephone. The Memorial Symptom Assessment Scale was used to categorise participants into groups reflecting sensitivity of symptom severity (slight, moderate and severe). The instruments demonstrated excellent internal consistency reliability, making them suitable for both group and individual comparisons. Clinical validity, construct validity, and discriminant validity were demonstrated by “known-groups” analysis, exploratory factor analysis and correlations, respectively. These new versions of the PedsQL Generic Core and Cancer Module are reliable, valid and sensitive measures of HRQOL in patients aged 16-25 years diagnosed with cancer or a blood disorder. The measures will soon be available for use as outcome measures in clinical trials and clinical practice with this age cohort in Australasia and internationally.

In the last thirty years there have been many research studies which have examined the reasons why adolescents and young adults engage in sexual behaviours. Most of these studies have lacked a theoretical basis, Consequently there are many links made between variables, but no consistency across studies, or attempts to develop an underlying theory to explain the results. However, there have been theoretical models developed to explain adolescents’ and young adults’ sexual decision making. Unfortunately, many of these models have not been empirically validated. This thesis attempts to address these deficiencies in the literature by utilising a theory of behaviour and applying it to adolescent and young adult sexual decision making. This theory is the Theory of Planned Behaviour (TPB). Two longitudinal studies were conducted to examine the utility of an adaptation of the TPB to sexual decision making among adolescents and young adults. In the first study 58 adolescent males, aged between 14 years and 18 years participated in a longitudinal study using a questionnaire adapted from the Depth of Sexual Involvement Scale. In the second study, 194 young adults (156 female, 38 male) aged between 18 years and 21 years participated in a similar study. The first study found that intention to engage in behaviour was well predicted, although some of the variables in the model, did not in fact, contribute significantly to the prediction. The prediction of behaviour was less strong than that of intention. Study two found that intention to engage in behaviours was well predicted by the model. However, the degree to which intention led to behaviour was not well predicted. Overall, the results of these studies suggest that the TPB is a good theoretical basis from which to launch a systematic and theoretically informed explanation of adolescent and young adult sexual decision making. However, other factors may need to be added to the model to fully describe the decision making process and accurately predict behaviour. Suggestions are made for future research, as well as interventions that may arise as more knowledge is gathered using this paradigm.

The purpose of the present research study was to produce a global, cumulative model of number concept development for children between the ages of two and eight years old. The theoretical and methodological orientation of this study was greatly influenced by Richard Young's production system analysis of seriation by young children (Young, 1971, 1976) and by Newell's (1973) seminal paper, ‘You can't play twenty questions with nature and win’. The methodology used in this investigation thus was as follows. A series of complex number tasks encompassing many aspects of the concept of number were developed. Five children aged between three and seven years then were videotaped while performing some of these complex number tasks. From a detailed protocol analysis of the video-recordings, computer simulation models written in the production system language PSS3 (Ohlsson, 1979) were produced. Specific production system models were produced for each of following aspects of the children's number knowledge: (i) sharing of discrete quantities; (ii) comparison of shares; and (iii) conservation/addition/subtraction of number. These domain-specific models were based on the converging experimental evidence obtained from each of the children’s responses to variants of the complex number tasks. Each child thus received a different set of problems which were chosen systematically in order to clarify particular features of the child's abilities. After a production system model for each child had been produced within a domain, these models were compared and contrasted. From this analysis, developmental trends within the domain were identified and discussed. The research and educational implications of these developmental trends then were discussed. In the concluding parts of this study, the children's domain-specific production system models were cumulated into global, comprehensive models which accurately represented their behaviour in a variety of number tasks. These comprehensive models were compared and contrasted and general developmental trends in young children's number knowledge were identified and discussed.

My interest in coping and survival of young men is my main motivation for undertaking the field study which this thesis describes. It developed from my concern at the continuing high level of young male suicide. I begin with some background discussion which shows some examples of how the community has been informed, particularly on youth suicide, by reviewing some of the media and government attention to these issues. Because suicidal behaviour is a gendered social phenomenon, this is followed by a discussion of some of the problems inherent in the hegemonic masculinity of young men. I then set out the underlying assumptions, the purpose, aims and theoretical framework of the study. The main theoretical underpinnings of the study are the theory of poststructuralism, as explained by the noted writer on gender and education, Bronwyn Davies. The other major components are Aaron Antonovsky's concepts of Salutogenesis and the Sense of Coherence. Minor but nevertheless important reference is also made to Edward Sampson's idea of the dialogic nature of the self. Following this are two critical reviews of relevant literature. The first addresses studies of resiliency and coping, while the second examines papers given at recent Australian conferences on suicide prevention. Following that I describe the methodology of the study before undertaking an analysis and interpretation of selected transcripts of interviews. This is an exploratory attempt at applying postructuralist discourse analysis to the social problem of male coping skills and male youth suicide. The results describe various discourses young men used in unstructuied interviews to explain how they cope when they feel down or depressed. The main conclusion from the results is that formation of small, confidential, supportive discussion groups for marginalised young men can be useful for sharing and developing coping skills and improving their management of stressors, which are everpresent in the environment. It is argued that the proliferation of such support groups for young men could have long term benefits in reducing the statistics of young male suicide by encouraging young men to share their techniques or behaviours of coping with their peers.

PART I Open education is defined operationally in terms of the Roland Earths (1971) open education scale plus Bob Young's curriculum scale based upon Basil Bernstein's classification of educational knowledge (collected versus integrated codes). Young's scale on the organization of curriculum knowledge is considered to make explicit ideas partially implicit in the Barth Scale as well as adding a new dimension. This definition of open education has three unifying closely related principles: (i) respect for students as persons (ii) a view of knowledge being in part a personal construct (iii) the extent by which the contents of the curriculum stand in open relation to each other. The limitations of the study and its relevance to ACT schools are stated. The literature on open education is reviewed and criticism is examined. The most important writers on open education influencing the development of the authors ideas were - Roland Barth, Tinsley Beck, Basil Bernstein, Hugh Petrie, Herbert Walberg and Susan Christie Thomas, and Bob Young. PART II A short personal history of the study is given. This outlines the development of the author's ideas and explains how the survey was conducted (plus its problems). An extensive analysis of the survey data was undertaken in terms of ten research questions posed. These related to:- (i) characteristics of respondents (ii) representativeness of the samples (iii) reliability of the instruments (Barth, Young) (iv) unity of the total Barth-Young scale (v) differences between primary teachers, secondary teachers and parents' responses (vi) factorial composition of the scales (vii) a comparison of the logical and factorial dimensions of the scales (viii) comments of respondents (ix) implications of the research (x) further research required. In general the survey data was consistent with the theory in Part I, though it also indicated there was a need for further development of the Barth-Young Scale.

The merger between Arthur Andersen (AA) and Ernst & Young (EY) in Australia was announced on the 16th May 2002. The merger was the culmination of seven months of speculation and drama surrounding the future of AA, following its involvement in the collapse of Enron in the United States of America (US). With the number of Big N firms having been reduced to four, concerns were raised over the impact of the merger on the competitiveness of the Australian audit services market (Boreham, 2002; Robertson, 2002; Hamilton et al., 2008). The objective of the thesis is to evaluate the impact of the merger of AA and EY on the market for audit services in Australia. In this regard, consideration is given to two specific questions. First, whether the Australian audit services market became less competitive subsequent to the merger of AA and EY. Second, whether any benefits, either in relation to audit pricing or efficiency, accrued to the firms involved as a consequence of the merger. In order to address these objectives, the impact of the merger on Australian listed firms is examined. This was done for both the market as a whole, as well as for the clients of EY. The sample was drawn from the 1271 available firms on the Australian Stock Exchange (ASX) in 2002. The results show that the audit services market in Australia is still competitive subsequent to the merger of AA and EY. This is so, even though the changes in concentration would suggest that anti-competitive effects could be occurring. One possible explanation for these findings is that the measures of market concentration as identified in the industrial organization literature are difficult to apply to audit firms. Additionally, the lack of benefit to EY from the merger, either through increased pricing or efficiency, may simply be due to 2002 being too early for benefits to be realised, possibly due to the stickiness of audit service fees (Ferguson et al., 2005) or merger implementation issues (Lawrence and Glover, 1998).
