Generic models of job stress, such as the Job Strain Model (JSM), have recently been criticised for focusing on a small number of general work characteristics while ignoring those that are occupation-specific (Sparks & Cooper, 1999). However this criticism is based on limited research that has not examined the relative influence of all three dimensions of the JSM - job demand, job control and social support - and job-specific stressors. The JSM is the most commonly used model underpinning large-scale occupational stress research (Fox, Dwyer, & Ganster, 1993) and is regarded as the most influential model in the research on the psycho-social work environment, stress and disease in recent times (Kristensen, 1995). This thesis addresses the lack of information on the relative influence of the JSM and job-specific stressors by assessing the capacity of an augmented JSM to predict the strain experienced by managers and professional Australian footballers. The augmented JSM consisted of job-specific stressors in addition to the generic components of the model. Managers and professional Australian footballers represent two very different occupational groups. While the day-today roles of a manager include planning, organising, monitoring and controlling (Carroll & Gillen, 1987), the working life of a professional Australian footballer revolves around preparing for and playing football (Shanahan, 1998). It was expected that the large differences in the work undertaken by managers and professional Australian footballers would maximise the opportunities for identifying job-specific stressors and measuring the extent that these vary from one group to the next. The large disparity between managers and professional footballers was also used to assess the cross-occupational versatility of the JSM when it had been augmented by job-specific stressors. This thesis consisted of three major studies. Study One involved a survey of Australian managers, while studies Two and Three focused on professional Australian footballers. The latter group was under-represented in the literature, and as a result of the lack of information on the stressors commonly experienced by this group, an in-depth qualitative study was undertaken in Study Two. The results from Study Two then informed the survey of professional footballers that was conducted in Study Three. Contrary to previous research examining the relative influence of generic and job-specific stressors, the results only provided moderate support for augmenting the JSM with job-specific stressors. Instead of supporting the versatility of the augmented JSM, the overall findings reinforced the broad relevance of the original JSM. Of the four health outcomes measured in Studies One and Three, there was only one - the psychological health of professional Australian footballers - where the proportion of total variance explained by job-specific stressors exceeded 13%. Despite the generally strong performance of the JSM across the two occupational groups, the importance of demand, control and support diminished when examining the less conventional occupation of professional football. The generic model was too narrow to capture the highly specific work characteristics that are important for this occupational group and, as a result, the job-specific stressors explained significantly more of the strain over and above that already provided by the generic model. These findings indicate that when investigating the stressors experienced by conventional occupational groups such as managers, the large amount resources required to identify job-specific stressors are unlikely to be cost-effective. In contrast, the influence of the more situation specific stressors is significantly greater in unconventional occupations and thus the benefits of identifying these non-generic stressors are more likely to outweigh the costs. Studies One and Three identified strong connections between job-specific stressors and important characteristics of the occupation being studied. These connections were consistent with previous research and suggest that before attempting to identify job-specific stressors, researchers need to first become familiar with the nature and context of the occupation. The final issue addressed in this thesis was the role of work and non-work support. The findings indicate that the support provided by supervisors and colleagues was a significant predictor of wellbeing for both managers and professional footballers. In contrast, the level of explained strain accounted for by non-work support was not significant. These results indicate that when developing strategies to protect and enhance employee well-being, particular attention should be given to monitoring and, where necessary, boosting the effectiveness of work-based support. The findings from this thesis have been fed back to the management and sporting communities via conference presentations and peer-reviewed journals (refer pp 220-221). All three studies have been presented at national and international conferences and, overall, were well received by participants. Similarly, the methods, results and major findings arising from Studies One and Two have been critiqued by anonymous reviewers from two international journals. These papers have been accepted for publication in 2001 and 2002 and feedback from the reviewers indicates that the findings represent a significant and unique contribution to the literature. The results of Study Three are currently under review by a sports psychology journal.

A range of factors, both internal and external, is creating changes in teaching and teachers’ professional lives. Information and Communication Technology (ICT) is just one of the major changes impacting on the teaching profession. As teachers face intense pressure to adapt to this tsunami, this study aims to investigate ways in which teachers can be helped. In South Australia, where this study is set, all teachers in Government schools are expected to be "ICT Smart", i.e. able to use appropriate forms of ICT to enhance the teaching and learning environment of their classrooms. From the researcher’s involvement for over a decade in professional development for teachers, and from visits to many schools, it appears that numerous teachers have not reached this standard. The greatest need is in Reception to Year 7 schools where the average age of teachers is nearly 50. Because no state-wide data exists, this study is intended to establish if there is a problem and if there is, to identify specific needs and offer possible solutions. The study is comprised of four parts: Part A, the Introduction gives an overview of the inter-relationships between these parts and the overall Folio. It establishes the setting and provides a rationale for the study and its focus on Professional Development in Information and Communication Technology. Part B, the Elective Research Studies, follows the writer’s involvement in this field since the 1980s. It establishes the theme of "Moving best practice in ICT from the few to the many" which underlies the whole study. Part C, the Dissertation, traces the steps taken to investigate the need for professional development in ICT. This is achieved by analysing and commenting on data collected from a state-wide survey and a series of interviews with leading figures, and by providing a review of the relevant literature and past and existing models of professional development. Part D, Final Comments, provides an overview of the whole Folio and a reflection on the research that has been conducted. The findings are that there is widespread dissatisfaction with existing models and that there is an urgent need for professional development in this area, because nearly 20% of teachers either do not use computers or are considered to be novice users. Another 25% are considered to be below not yet "ICT Smart". Less than 10% of ICT co-ordinators have a formal qualification in the field but more than 85% of them are interested in a Masters program. The study offers solutions in Part B where there is a discussion of a range of strategies to provide on-going professional development for teachers. Chapter 9 provides an outline of a proposed Masters level program and offers suggestions on how it could be best delivered. This program would meet the identified needs of ICT co-ordinators. The study concludes with a series of recommendations and suggestions for further research. The Education Department must address these urgent professional development needs of teachers, particularly those in the more remote country regions. There needs to be a follow-up survey to establish to what extent teachers in South Australia are now "ICT Smart ".

Background : This study sought to elucidate the extent to which behaviour support plans for people with intellectual disability are inclusive of best practice criteria, with a comparison made prior to and following proclamation of the Disability Act (2006) in Victoria, Australia.

Method : This study used a data collection instrument developed by the researchers incorporating best practice criteria as identified in the review of literature and Victorian legislative requirements. The instrument was used to assess a sample of behaviour support plans.

Results : Best practice criteria are inadequately included in behaviour support plans with little difference between pre- and post-Act plans.

Conclusion : The results of this study indicate that disability support staff are ill equipped to undertake the complex assessments, planning, and implementation associated with behaviour support strategies, despite the legislative framework that guides and directs this intervention

Atascadero State Hospital (ASH) is a maximum-security forensic hospital that houses male patients with a wide range of psychiatric diagnoses. Psychopaths at this institution appear to be a heterogeneous group of individuals who, while sharing core personality characteristics, manifest substantial variability in their behavior. Identifying subtypes within this clinical classification can have implications for patient treatment and management, as well as for the safety of the staff who work with them and for the communities to which they will eventually return. Several means of identifying subtypes have been proposed in the literature, and potential subgroups have been identified. Clinical observations at ASH have suggested 4 possible subtypes of psychopathy: narcissistic, borderline, sadistic, and antisocial. Issues related to the conceptualization of psychopathy are addressed, recognizing that additional data are needed to understand the observed variations in cases of psychopathy.

Objective To assess the effect of food taxes and subsidies on diet, body weight and health through a systematic review of the literature.

Methods We searched the English-language published and grey literature for empirical and modelling studies on the effects of monetary subsidies or taxes levied on specific food products on consumption habits, body weight and chronic conditions. Empirical studies were dealing with an actual tax, while modelling studies predicted outcomes based on a hypothetical tax or subsidy.

Findings Twenty-four studies met the inclusion criteria: 13 were from the peer-reviewed literature and 11 were published on line. There were 8 empirical and 16 modelling studies. Nine studies assessed the impact of taxes on food consumption only, 5 on consumption and body weight, 4 on consumption and disease and 6 on body weight only. In general, taxes and subsidies influenced consumption in the desired direction, with larger taxes being associated with more significant changes in consumption, body weight and disease incidence. However, studies that focused on a single target food or nutrient may have overestimated the impact of taxes by failing to take into account shifts in consumption to other foods. The quality of the evidence was generally low. Almost all studies were conducted in high-income countries.

Conclusion Food taxes and subsidies have the potential to contribute to healthy consumption patterns at the population level. However, current evidence is generally of low quality and the empirical evaluation of existing taxes is a research priority, along with research into the effectiveness and differential impact of food taxes in developing countries.

This paper analyses multicultural artists' perceptions of their employment and career prospects in the arts. We do this first by reviewing the relatively small body of literature on multicultural artists' careers and supplement that with a literature review of general vocational development literature. Further, we examine the degree to which multicultural artists possess the generic employability skills necessary to gain and retain employment in Australia. We use data from a small-scale qualitative study, conducted in Western Australia, which identified artists' perceptions of barriers to participation in the arts in general and to paid employment in particular. From the literature and studied data, we propose a 'Dual Responsibilities Framework for Career Management of Multicultural Artists'.

The hydrogen diffusion and phase transformation in a titanium particle were studied based on thermodynamic calculation. The mechanisms of hydrogen diffusion in different phases (alpha-Ti, beta-Ti and TiHx) were analyzed. A mobility database was developed for titanium– hydrogen system based on the experimental works on hydrogen diffusion coefficient reported in literature and the fundamental of diffusion. To implement the calculation, a commercial software package for the simulation of diffusion-controlled phase transformation was used. The hydrogen diffusion process, hydrogen distribution, phase transformation and phase growth rate during hydrogenization of a titanium particle at temperatures of 560 K, 800K and 1000K were discussed. The thermodynamics and kinetics analysis provided quantitative insight into the diffusion process and improved the understanding of diffusion mechanism and phase transformation.

Background: Placements are of particular importance due to the richness of learning associated with placement experiences and the wider links they represent to industry and the community. Students often refer to placements as the most significant, productive and memorable component of their training. Importantly, placements also provide the opportunity for students to become work ready, i.e., integrate their knowledge into a new set of employable skills and personal qualities. There is now increased emphasis on employability by employers and universities alike; in fact, it now represents a critical performance measure for Australian universities. Despite these key points, there appears to be inconsistencies in approaches to maximising work placements across and within Universities. Assessment centre methodology may represent a useful approach to standardise and optimise work placements for all stakeholders. Assessment centre methodology has been used successfully for selection purposes in industry for the past 50 years. However, their use as a developmental tool is less prominent. Furthermore, their application in the higher education setting, particularly in the context of placements and student development appears under researched.
Overview of issue: Only one published study was found that reported the use of a developmental assessment centre with a post-graduate sample. That study took place over 10 years ago when the concept of employability was still gaining recognition and work placements were less common. The current paper reviews this unique concept in the context of the existing literature and the current needs of Universities, employers and students.
Discussion: It is argued that the reconsideration of assessment centre methodology for development represents an innovative approach to consistently maximising work placement outcomes, experiences and employability.
Conclusions: Given the importance and increased use of placements, the application of assessment centre methodology within the placement curriculum warrants further research. This methodology represents a standardised approach for implementation within a range of placement programs to enhance student development, placement outcomes and employability.

BACKGROUND: An influx of African migrants and refugees can strain a host country's blood services, because often migrants have unique blood needs that cannot be sourced from local donors. To increase blood donation by the new migrants, host country blood services need to understand how blood and blood donations are viewed by immigrant communities, because recruitment models that are not culturally adapted may have limited success.

STUDY DESIGN AND METHODS:
Nine focus groups representing a cross-section of Australian-based African communities were conducted in multiple languages, facilitated by bilingual workers. The qualitative protocol was guided by the literature on blood donation by African migrants and communities in Africa. Thematic analysis identified the relevance of issues previously included in the literature and whether other issues facilitated or prohibited blood donation.

RESULTS: Home country cultural issues were not generally raised as barriers to donation, and respondents were positively disposed toward donation. Home country experiences shaped respondents' views in Australia. Participants focused on assisting “individuals in need,” rather than giving to a blood service that many viewed with suspicion because of issues in their home country. There was a lack of knowledge about the donation process in Australia. More importantly, respondents perceived that their blood would not be wanted, based on a perception of host country mistrust and discrimination.

CONCLUSION: Developing an intervention that encourages migrants to donate blood needs to be culturally focused. It appears that addressing perceptions based on home country experiences is essential. Overcoming a general perception of discrimination is beyond any blood service, but there can be an attempt to ensure that blood donation is seen as an inclusive process—blood from everyone, for everyone.
