Managerial changes to Australian universities have had considerable impact on employees. In this paper we consider some of these changes and apply a theory known as the democratic deficit to them. This theory was developed from the democratic critique of managerialism, as it has been applied in the public sector in countries with Westminster-type political systems. This deficit covers the weakening of accountability through politicisation, the denial of public values through the use of private sector performance practices, and the hollowing out of the state through the contracting out and privatisation of public goods and services, and the redefinition of citizens as customers and clients. We suggest that the increased power of managers, expansion of the audit culture, and the extensive use of contract employment seem to be weakening the democratic culture and role of universities in part by replacing accountability as responsibility with accountability as responsiveness.

This paper is drawn from a 2012-2013 OLT National Teaching Fellowship investigating the agencies impacting on whole-of course curriculum design in initial teacher education. The chief of these is AITSL (Australian Institute for Teaching and School Leadership) through the Australian Professional Standards for Teachers at Graduate level and the Program Accreditation Standards. This paper will begin with a discussion of the requirements on both beginning teachers and initial teacher education programs in regard to ICT (both content and pedagogy). It will then present case studies from four universities whose degree programs have been approved for implementation in 2014. It will focus on how each institution has responded to the APST as well as accreditation requirements. This will be based on responses to surveys to selected institutions and with one on one interviews to capture rich data. From this, it will draw a contemporary profile of how institutions are rising to the real requirements of ICT pedagogy within the regulatory constraints now in place. The methodology employed is qualitative and is based on document analysis enriched by interview data. It is important to know, as a profession, how future teachers are being introduced to and immersed in digital learning environments.

The exchange of iron species from iron (III) chloride solutions with a strong acid cation resin has been investigated in relation to a variety of water and wastewater applications. A detailed equilibrium isotherm analysis was conducted wherein models such as Langmuir Vageler, Competitive Langmuir, Freundlich, Temkin, Dubinin Astakhov, Sips and Brouers-Sotolongo were applied to the experimental data. An important conclusion was that both the bottle-point method and solution normality used to generate the ion exchange equilibrium information influenced which sorption model fitted the isotherm profiles optimally. Invariably, the calculated value for the maximum loading of iron on strong acid cation resin was substantially higher than the value of 47.1 g/kg of resin which would occur if one Fe3+ ion exchanged for three “H+” sites on the resin surface. Consequently, it was suggested that above pH 1, various iron complexes sorbed to the resin in a manner which required less than 3 sites per iron moiety. Column trials suggested that the iron loading was 86.6 g/kg of resin when 1342 mg/L Fe (III) ions in water were flowed at 31.7 bed volumes per hour. Regeneration with 5 to 10 % HCl solutions reclaimed approximately 90 % of exchange sites.

This article is concerned with the many connections between creative work and workers, and education work and industries. Employment in the education sector has long been recognised as a significant element in creative workers’portfolio careers. Much has been written, for exam- ple, about the positive contribution of ‘artists in schools’ initiatives. Australian census analyses reveal that education is the most common industry sector into which creative workers are ‘embedded’, outside of the core creative industries. However, beyond case studies and some survey research into arts instruction and instructors, we know remarkably little about in which education roles and sectors creative workers are embedded, and the types of value that they add in those roles and sectors. This article reviews the extant literature on creative work and workers in education, and presents the findings of a survey of 916 graduates from creative undergraduate degrees in Australia. The findings suggest that education work is very common among creative graduates indeed, while there are a range of motivating factors for education work among creative graduates, on average they are satisfied with their careers, and that creative graduates add significant creative-cultural and creative-generic value add through their work.

In 2012, the Australian Council of Deans of Education (ACDE), through the Queensland University of Technology, led a MATSITI project focusing on issues related to the retention, support and graduation of Aboriginal and Torres Strait Islander teachers in initial Teacher Education programs across Australia. While some of the barriers that impact on the graduation of Aboriginal and Torres Strait Islander teachers are well, known, this was the first large-scale Australian study to look at the issues nationally and in depth. Thirty-four Teacher Education programs across the country were audited, meetings were held in each state, both Aboriginal and Torres Strait Islander and non-Indigenous Faculty were consulted and approximately 70 Aboriginal and Torres Strait Islander pre-service teachers interviewed. This paper reports on the outcomes of that project, including the evidence that while recruitment into Teacher Education has, in some sites, reached parity, retention rates are well-below expected across the nation. The paper focuses both on the quantitative data and, even more significantly, on the voices of the pre-service teachers themselves, offering insights into the ways forward. As a result of this study, Deans and Heads of School of Teacher Education programs across the country have developed Action Plans alongside their university's Indigenous Higher Education Centres to improve support and retention of Aboriginal and Torres Strait Islander teachers.

OBJECTIVE Impaired regulation of the hypothalamic-pituitary-adrenal (HPA) axis and hyper-activity of this system have been described in patients with psychosis. Conversely, some psychiatric disorders such as post-traumatic stress disorder (PTSD) are characterised by HPA hypo-activity, which could be related to prior exposure to trauma. This study examined the cortisol response to the administration of low-dose dexamethasone in first-episode psychosis (FEP) patients and its relationship to childhood trauma. METHOD The low-dose (0.25 mg) Dexamethasone Suppression Test (DST) was performed in 21 neuroleptic-naive or minimally treated FEP patients and 20 healthy control participants. Childhood traumatic events were assessed in all participants using the Childhood Trauma Questionnaire (CTQ) and psychiatric symptoms were assessed in patients using standard rating scales. RESULTS FEP patients reported significantly higher rates of childhood trauma compared to controls (p = 0.001) and exhibited lower basal (a.m.) cortisol (p = 0.04) and an increased rate of cortisol hyper-suppression following dexamethasone administration compared to controls (33% (7/21) vs 5% (1/20), respectively; p = 0.04). There were no significant group differences in mean cortisol decline or percent cortisol suppression following the 0.25 mg DST. This study shows for the first time that a subset of patients experiencing their first episode of psychosis display enhanced cortisol suppression. CONCLUSIONS These findings suggest there may be distinct profiles of HPA axis dysfunction in psychosis which should be further explored.

Objective: The aim of the present pilot study was to examine the effectiveness of a relaxation massage therapy programme in reducing stress, anxiety and aggression on a young adult psychiatric inpatient unit. Method: This was a prospective, non-randomized intervention study comparing treatment as usual (TAU) with TAU plus massage therapy intervention (MT) over consecutive 7 week blocks (May–August 2006). MT consisted of a 20 min massage therapy session offered daily to patients during their period of hospitalization. The Kennedy Nurses’ Observational Scale for Inpatient Evaluation (NOSIE), the Symptom Checklist-90–Revised (SCL-90-R), the State–Trait Anxiety Inventory (STAI) and stress hormone (saliva cortisol) levels were used to measure patient outcomes at admission and discharge from the unit. The Staff Observation Aggression Scale–Revised (SOAS-R) was used to monitor the frequency and severity of aggressive incidents on the unit. Results: There was a significant reduction in self-reported anxiety (p < 0.001), resting heart rate (p < 0.05) and cortisol levels (p < 0.05) immediately following the initial and final massage therapy sessions. Significant improvements in hostility (p = 0.007) and depression scores (p < 0.001) on the SCL-90-R were observed in both treatment groups. There was no group×time interaction on any of the measures. Poor reliability of staff-reported incidents on the SOAS-R limited the validity of results in this domain. Conclusions: Massage therapy had immediate beneficial effects on anxiety-related measures and may be a useful de-escalating tool for reducing stress and anxiety in acutely hospitalized psychiatric patients. Study limitations preclude any definite conclusions on the effect of massage therapy on aggressive incidents in an acute psychiatric setting. Randomized controlled trials are warranted.

The experience of stress is commonly implicated in models of the onset of psychotic disorders. However, prospective studies investigating associations between biological markers of stress and the emergence of psychotic disorders are limited and inconclusive. One biological system proposed as the link between the psychological experience of stress and the development of psychosis is the Hypothalamic-Pituitary-Adrenal (HPA) axis. This paper summarizes and discusses evidence supporting a role for HPA-axis dysfunction in the early phase of schizophrenia and related disorders. METHOD A selective review of psychiatric and psychological research on stress, coping, HPA-axis, the hippocampus and psychotic disorders was performed, with a particular focus on the relationship between HPA-axis dysfunction and the onset of psychotic disorders. RESULTS Individual strands of past research have suggested that the HPA-axis is dysfunctional in at least some individuals with established psychotic disorders; that the hippocampus is an area of the brain that appears to be implicated in the onset and maintenance of psychotic disorders; and that an increase in the experience of stress precedes the onset of a psychotic episode in some individuals. Models of the onset and maintenance of psychotic disorders that link these individual strands of research and strategies for examining these models are proposed in this paper. CONCLUSIONS The current literature provides some evidence that the onset of psychotic disorders may be associated with a higher rate of stress and changes to the hippocampus. It is suggested that future research should investigate whether a relationship exists between psychological stress, HPA-axis functioning and the hippocampus in the onset of these disorders. Longitudinal assessment of these factors in young people at 'ultra' high risk of psychosis and first-episode psychosis cohorts may enhance understanding of the possible interaction between them in the early phases of illness.

The provision of effective training of supervisors and operators is essential if sugar factories are to operate profitably and in an environmentally sustainable and safe manner. The benefits of having supervisor and operator staff with a high level of operational skills are reduced stoppages, increased recovery, improved sugar quality, reduced damage to equipment, and reduced OH&S and environmental impacts. Training of new operators and supervisors in factories has traditionally relied on on-the-job training of the new or inexperienced staff by experienced supervisors and operators, supplemented by courses conducted by contractors such as Sugar Research Institute (SRI). However there is clearly a need for staff to be able to undertake training at any time, drawing on the content of online courses as required. An improved methodology for the training of factory supervisors and operators has been developed by QUT on behalf of a syndicate of mills. The new methodology provides ‘at factory’ learning via self-paced modules. Importantly, the training resources for each module are designed to support the training programs within sugar factories, thereby establishing a benchmark for training across the sugar industry. The modules include notes, training guides and session plans, guidelines for walkthrough tours of the stations, learning activities, resources such as videos, animations, job aids and competency assessments. The materials are available on the web for registered users in Australian Mills and many activities are best undertaken online. Apart from a few interactive online resources, the materials for each module can also be downloaded. The acronym SOTrain (Supervisor and Operator Training) has been applied to the new training program.

This paper explores Rizvi and Lingard’s (2010) idea of the “local vernacular” of the global education policy trend of using high-stakes testing to increase accountability and transparency, and by extension quality, within schools and education systems in Australia. In the first part of the paper a brief context of the policy trajectory of National Assessment Program – Literacy and Numeracy (NAPLAN) is given in Australia. In the second part, empirical evidence drawn from a survey of teachers in Western Australia (WA) and South Australia (SA) is used to explore teacher perceptions of the impacts a high-stakes testing regime is having on student learning, relationships with parents and pedagogy in specific sites. After the 2007 Australian Federal election, one of Labor’s policy objectives was to deliver an “Education Revolution” designed to improve both the equity and excellence in the Australian school system1 (Rudd & Gillard, 2008). This reform agenda aims to “deliver real changes” through: “raising the quality of teaching in our schools” and “improving transparency and accountability of schools and school systems” (Rudd & Gillard, 2008, p. 5). Central to this linking of accountability, the transparency of schools and school systems and raising teaching quality was the creation of a regime of testing (NAPLAN) that would generate data about the attainment of basic literacy and numeracy skills by students in Australian schools.

In Australian early years education, consultation and partnerships with Aboriginal and Torres Strait Islander people are central to embedding Indigenous perspectives. Building sustained and reciprocal partnerships with Aboriginal and Torres Strait Islander people supports access to local knowledges and perspectives to inform curriculum planning, as well as protocols and community processes, and contemporary responses to colonisation. Drawing on data from a doctoral study about embedding Aboriginal and Torres Strait Islander perspectives in early childhood education curricula, this paper examines interactional patterns in consultations between non-Indigenous early childhood educators and Indigenous people in real and supposed form. Data is read through whiteness studies literature and related critiques to identify how the educators positioned Indigenous people in interactional patterns and how the mobilisation of colonial discourses impacted the potential for reciprocity and sustained partnerships, despite the best of intentions. Colonial traces of positioning Indigenous people as informants, targeted resources or knowledge commissioners were shown to be most salient in interactional patterns. While these findings are contextualised within Australia, I suggest they have applicability in examining approaches to embedding Indigenous perspectives in education curricula in other colonising contexts such as Canada and New Zealand.

Abstract: The H-1 NMR spectra of N-(2-pyridyl), N'-(3-pyridyl)ureas and N-(2-pyridyl), N'-(4-pyridyl)ureas in CDCl3 and (CD3)(2)CO have been assigned with the aid of COSY and NOE experiments and chemical shift and coupling constant correlations, The C-13 NMR spectra in CDCl3 were analysed utilizing the HETCOR and proton coupled spectra, The H-1 NMR spectra, NOE effects and MINDO/3 calculations have been utilized to show that the molecular conformation of these compounds has the 2-pyridyl ring coplanar with the urea plane with the N-H group hydrogen bonded to the nitrogen of the 2-pyridyl group on the other urea nitrogen while the 3/4-pyridyl group rotates rapidly about the N-C-3/N-C-4 bond.

The first stereoselective total synthesis of (+/-)-allo-cedrol 20, an enantiomer of khusiol and a complex sesquiterpene having a novel tricyclo[5.2.2.0(1,5)]undecane framework, is reported from 8-methoxytricyclo[6.2.2.0(1,6)]dodec-6-en-9-one 6c. The methodology involves preparation of 9-methoxytricyclo[7.2.1.0(1,6)]dodec-6-en-8-one 12 from 6c and its conversion through the compounds 8-benzyloxy-7,7-dimethyl-9-methoxytricyclo[7.2.1.0(1,6)]dodec-5-ene 38, 7-benzyloxy-8-methoxy-2,6,6-trimethyltricyclo[6.2.1.0(1,5)]undecane 48 into 8-methoxy-2,6,6-trimethyltricyclo[6.2.1.0(1,5)]undecan-7-one 49. Wittig reaction of 49 affords the olefin 50 which has been smoothly rearranged into khusione 51. Metal-ammonia reduction of khusione under specific conditions affords (+/-)-allo-cedrol. Thus, bridgehead substitution of a methoxy group by a methyl group is the key reaction in this synthesis. In an alternative strategy, attempted conversion of 8-methoxy-2-methyltricyclo[6.2.1.0(1,5)]undec-5-en-7-one 16 into khusione 37 results in an inseparable mixture of the isomers. A notable observation in this synthesis is the unusual formation of a gamma-alkylated product 27 during Woodward methylation of 16.
