The role of the screen producer is ramifying. Not only are there numerous producer categories, but the screen producer function is also found on a continuum across film, television, advertising, corporate video, and the burgeoning digital media sector. In recent years, fundamental changes to distribution and consumption practices and technologies should have had a correlate impact on screen production practices and on the role of existing screen producers. At the same time, new and recent producers are learning and practicing their craft in a field that has already been transformed by digitisation and media convergence. Our analysis of the work, experience and outlook of screen producers in this chapter is based on data collected in the Australian Screen Producer Survey (ASPS), a nation-wide survey conducted by the ARC Centre of Excellence for Creative Industries and Innovation, the media marketing firm Bergent Research, and the Centre for Screen Business at the Australian Film, Television and Radio School (AFTRS) in 2008/09 and 2011. We analyse the results to better understand the practice of screen production in a period of industry transition, and to recognise the persistence of established production cultures that serve to distinguish different industry sectors.

Students making the transition from high school to university often encounter many stressors and new experiences. Many students adjust successfully to university; however, some students do not, often resulting in attrition from the university and mental health issues. The primary aim of the current study was to examine the effects that optimism, self-efficacy, depression, and anxiety have on an individual's life stress and adaptation to university. Eighty-four first-year, full-time students from the Queensland University of Technology (60 female, 24 male) who had entered university straight from high school completed the study. Participants completed a questionnaire assessing their levels of optimism, self-efficacy, depression, anxiety, perceived level of life stress and adaptation to university. In line with predictions, results showed that optimism, depression, and anxiety each had a significant relationship with students’ perceived level of stress. Furthermore, self-efficacy and depression had a significant relationship with adaptation to university. We conclude that students with high levels of optimism and low levels of depression and anxiety will adapt better when making the transition from high school to university. In addition, students with high levels of self-efficacy and low levels of depression will experience less life stress in their commencement year of university. The implications of this study are outlined.

BACKGROUND Mosquito-borne diseases are climate sensitive and there has been increasing concern over the impact of climate change on future disease risk. This paper projected the potential future risk of Barmah Forest virus (BFV) disease under climate change scenarios in Queensland, Australia. METHODS/PRINCIPAL FINDINGS We obtained data on notified BFV cases, climate (maximum and minimum temperature and rainfall), socio-economic and tidal conditions for current period 2000-2008 for coastal regions in Queensland. Grid-data on future climate projections for 2025, 2050 and 2100 were also obtained. Logistic regression models were built to forecast the otential risk of BFV disease distribution under existing climatic, socio-economic and tidal conditions. The model was applied to estimate the potential geographic distribution of BFV outbreaks under climate change scenarios. The predictive model had good model accuracy, sensitivity and specificity. Maps on potential risk of future BFV disease indicated that disease would vary significantly across coastal regions in Queensland by 2100 due to marked differences in future rainfall and temperature projections. CONCLUSIONS/SIGNIFICANCE We conclude that the results of this study demonstrate that the future risk of BFV disease would vary across coastal regions in Queensland. These results may be helpful for public health decision making towards developing effective risk management strategies for BFV disease control and prevention programs in Queensland.

Enormous progress has been made towards understanding the role of specific factors in the process of epithelial-mesenchymal transition (EMT); however, the complex underlying pathways and the transient nature of the transition continues to present significant challenges. Targeting tumour cell plasticity underpinning EMT is an attractive strategy to combat metastasis. Global gene expression profiling and high-content analyses are among the strategies employed to identify novel EMT regulators. In this review, we highlight several approaches to systematically interrogate key pathways involved in EMT, with particular emphasis on the features of multiparametric, high-content imaging screening strategies that lend themselves to the systematic discovery of highly significant modulators of tumour cell plasticity.

TCNQ·− radical anions (TCNQ = 7,7,8,8,-tetracyanoquinodimethane) form a wide range of semiconducting coordination polymers when coordinated to transition metals. Some such as CuTCNQ and AgTCNQ exhibit molecular switching and memory storage properties; others have intriguing magnetic properties and for example may behave as molecular magnets at low temperature. In this review, the electro- and photo-chemical synthesis and characterization of this important class of material is reviewed. In particular, the electrochemistry and the redox properties of TCNQ derivatives of coordination polymers based on Cu, Ag, Mn, Fe, Co, Ni, Zn and Cd transition metals are surveyed, with an emphasis on the mechanistic aspects of their electrochemical formation via nucleation–growth processes. Given that TCNQ is an extremely good electron acceptor, readily forming TCNQ•− and TCNQ2-, electrochemical reduction of TCNQ in the presence of a transition metal ion provides an ideal method for synthesis of metal-TCNQ materials by electrocrystallization from organic solvents and ionic liquids or solid-solid transformation using TCNQ modified electrodes from aqueous media containing transition metal electrolytes. The significance of the reversible formal potential (E0f) in these studies is discussed. The coupling of electrocrystallisation on electrode surfaces and microscopic characterization of the electrodeposited materials reveals a wide range of morphologies and phases which strongly influence their properties and applications. Since TCNQ also can be photo-reduced in the presence of suitable electron donors, analogous photochemical approaches to the synthesis of TCNQ-transition metal derivatives are available. The advantages of electrochemical and photochemical methods of synthesis relative to chemical synthesis are outlined.

Teachers in inclusive early education classrooms face competing pressures that are highlighted as children transition from play-based settings into formal school. Their challenge is to engage in pedagogical practice that caters for the complex range of school entrants. Yet the existing literature reports on transition challenges for separate groups of children rather than on shared needs or processes within diverse class populations. This study addressed this gap by investigating practices that supported transition in three Australian sites in which the populations represented different types of pedagogic challenge. Four themes regarding inclusion and transition were identified from a synthesis of the literature and applied to three cases. Results indicated that teachers adopted a range of approaches framed by the visibility of diversity, by classroom and school context and by the teachers’ professional transition in enacting changing policies. The results suggest that competing demands are balanced through dynamic, contextually framed strategies of relevance to both ECEC and schools.

Indigenous Australians are among the most unhealthy populations in the world and yet they reside in a country where the non-Indigenous population enjoys high standards of well-being. Education has been identified as the key mechanism for closing this equity gap. At school commencement many Indigenous children are already at risk of disengagement. This four-year longitudinal study of two Indigenous boys from a socially marginalised community examined key factors affecting transitional trajectories into school. While child characteristics affected level of achievement the critical factors in sustaining positive educational engagement were social support, school practices, inclusion of family and positive expectation.

This study reports on an intervention program designed to facilitate transition to school of a whole community of Indigenous Australian children who had previously not been attending. The children were from families displaced from their traditional lands and experienced on-going social marginalisation and transience. A social capital framework was employed to track change in the children’s social inclusion and family-school engagement for two years, from school entry. Sociometric measurement and interview techniques were applied to assess the children’s social connectedness and peer relationship quality. Using these data, analyses examined whether bonding within the group supported or inhibited formation of new social relationships. Although transience disrupted attendance, there was a group trend towards increased social inclusion with some evidence that group bonds supported bridging to new social relationships. Change in family-school engagement was tracked using multi-informant interviews. Limited engagement between school and families presented an on-going challenge to sustained educational engagement.

We appreciate Holmes' body of work relating to transitions within the Australian landscape, and welcome the opportunity to engage in a discussion on this topic. The paper to which Holmes refers (Bjørkhaug and Richards, 2008) examined the application of agricultural (rather than landscape) multifunctionality in both Norway and Australia. Of specific focus was how non-tradeable concerns, such as environmental sustainability, faired under these divergent systems. We argued that Norway's multifunctionality was strong, due to it being embraced at both the policy and actor level, whereas Australia's could be described as weak. This ‘weak multifunctionality’ that we observed in Australia was due to an emerging bi-lateral (state and federal) policy framework that advocated the importance of environmental values which was rarely embraced by landholders who found themselves trapped on the ‘agricultural treadmill’. The nature of the treadmill is that alternative forms of land use are unthinkable when on-farm investments have been made that support the status quo – to get bigger and/or more efficient. For many of the Australian landholders interviewed in relation to this study, efficiency in production was at odds with the values necessary to effect a transition toward multifunctionality. For instance, graziers in Central Queensland were unconvinced of the value of conserving native flora and fauna when economic viability can be better assured through clear felling native forests to increase the productive capacity of the land.

Nurse graduates indicate the transition from student of nursing to registered nurse (RN) is a difficult conversion. This impending change of role and accompanying higher expectations placed upon newly graduating RNs causes concern for students as their Bachelor of Nursing program nears completion. A career mentor scheme is suggested as a way to better prepare final year students for this transition. Evaluations indicate the positive impact the scheme has made on both mentors and mentees as it has enhanced their career development.
