Reflection and the promotion of reflective practice have become popular features of the design of educational programmes. This has often led to learning being more effectively facilitated. However, alongisde these positive initiatives have grown more disturbing developments under the general heading of reflection. They have involved both misconceptions of the nature of reflection which have led to instrumental or rule-following approaches to reflective activities, and the application of reflective strategies in ways which have sought inappropriate levels of disclosure from participants or involved otherwise unethical practices. The article examines the question: what constitutes the effective use of reflective activities? It argues that reflection needs to be flexibly deployed, that it is highly context-specific and that the social and cultural context in which reflection takes place has a powerful influence over what kinds of reflection it is possible to foster and the ways in which this might be done. The article concludes by exploring conditions in which reflective activities might appropriately be used in professional education

Purpose – This paper aims to explore the relationship between corporate social responsibility (CSR) disclosures and earnings quality proxied by earnings accruals. Specifically, we examine whether CSR disclosures are context-specific, that is, whether companies dominated by powerful stakeholders are obliged to behave in a responsible manner to constrain earnings management, thereby reporting higher-quality earnings to investors. Design/methodology/approach – This paper explores the relationship between CSR disclosures and earnings quality proxied by earnings accruals. Specifically, we examine whether CSR disclosures are context-specific, that is, whether companies dominated by powerful stakeholders are obliged to behave in a responsible manner to constrain earnings management, thereby reporting higher-quality earnings to investors. Findings – Results show that managers in an emerging economy manage earnings when they provide more CSR disclosures. Such earnings management is achieved through income increasing discretionary accruals. Furthermore, companies from export-oriented industries dominated by powerful stakeholders (international buyers) disclosing more CSR activities, provide transparent financial reports through constraining earnings management. Originality/value – The findings of this study are significant for both investors and policymakers. Investors should not take for granted that firms engage in CSR activities, behave ethically and provide transparent financial reports. As we document that firms might manipulate earnings through discretionary accruals and provide less transparent financial reports to shareholders, the credibility of firms’ CSR policies should be assessed with caution. Policies directing at promoting socially responsible practices instead of motivating the desired behaviour, may provide managers with additional incentives to utilise CSR for opportunistic behaviour. Thus, policymakers need to be cautious about this opportunistic behaviour and enhance monitoring to enforce social compliance. Possibly, some guidelines can be introduced to confirm that CSR disclosures are based on actual practice and not just a “green wash” statement to deceive stakeholders.

Aspirations for higher education by people from low socioeconomic status backgrounds are now a focus of government policy in many OECD nations. This is part of a global trend emphasizing the perceived benefits of ‘raising’ aspirations among under-represented groups as a social inclusion strategy to widen university participation, but also ultimately as a strategy to increase national competitiveness in the global knowledge economy. Yet despite its importance, aspiration tends to carry simplistic meanings in much higher education policy and practice. This paper attempts to craft a more nuanced account of the term, informed by four concept-clusters derived from sociological and philosophical literatures and research, and with a more mutual relation of public and private interests. It complements this ‘intellectual craftsmanship’ or ‘systematic reflection’ (Mills in The sociological imagination, 1959) with data drawn from a future-focused survey of secondary school students from low and low-mid socioeconomic status backgrounds in regional Australia. Results from the survey provide illustrations that help expand understandings of student aspirations for higher education, from a group presumed to be deficit in aspirations.

Short-term international practicum experience is now a feature of many university education programs in Australia in an attempt to engage students with the growing multi-cultural aspects of Australian life. The stated purposes of such practicum experiences generally highlight intercultural learning, which is associated with the development of intercultural sensitivity, cultural identity, global citizenship and global competence. This paper tracks and documents the early and developing attitudes and dispositions of a group of pre-service teachers (PSTs) and academic staffwho were engaged with the pilot project of a pre-service placement in Malaysian secondary schools. The behaviours associated with intercultural learning are observed in association with the students' responses to changing circumstances. The paper draws attention to lessons learnt about orientation for intercultural exchanges in the development of intercultural learning and suggests ways to enhance the development of intercultural understandings and minimize cultural difference through more targeted interventions.

© 2015 Australian Psychological Society. Objective: The use of self-practice and self-reflection has been proposed as an efficacious strategy in the training of therapists. It has been argued to enhance therapist skills, and a key factor in the development of expertise. This systematic literature review investigated the effect of self-practice and self-reflection on therapist skills development. Method: Studies were identified through Medline, Academic Search Complete, PsychINFO, PsycARTICLES, Proquest, ISI, CINAHL, Cochrane, and Scopus databases. Additional studies were identified through lateral searches of relevant papers' reference lists and direct correspondence with authors of unpublished material. The selection criteria were studies that investigated the effect of self-practice and/or self-reflection on therapist skill development. There was no restriction on sample sizes, design of studies, dates of publication, or peer-reviewed papers. All studies were published in English. Results: Ten studies were included in this review. A thematic analysis was undertaken to analyse qualitative data. Due to inconsistency in the variables investigated across the quantitative studies, quantitative results were not subject to a meta-analysis but simply reported. Finally, qualitative and quantitative data were juxtaposed in a meta-synthesis. Conclusion: The meta-synthesis revealed inconsistencies between the qualitative and quantitative literature and a gap in relation to declarative knowledge. Methodological limitations across studies are discussed and recommendations for future research provided.

BACKGROUND: Depression is widely considered to be an independent and robust predictor of Coronary Heart Disease (CHD), however is seldom considered in the context of formal risk assessment. We assessed whether the addition of depression to the Framingham Risk Equation (FRE) improved accuracy for predicting 10-year CHD in a sample of women.

DESIGN: A prospective, longitudinal design comprising an age-stratified, population-based sample of Australian women collected between 1993 and 2011 (n=862).

METHODS: Clinical depressive disorder was assessed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID-I/NP), using retrospective age-of-onset data. A composite measure of CHD included non-fatal myocardial infarction, unstable angina coronary intervention or cardiac death. Cox proportional-hazards regression models were conducted and overall accuracy assessed using area under receiver operating characteristic (ROC) curve analysis.

RESULTS: ROC curve analyses revealed that the addition of baseline depression status to the FRE model improved its overall accuracy (AUC:0.77, Specificity:0.70, Sensitivity:0.75) when compared to the original FRE model (AUC:0.75, Specificity:0.73, Sensitivity:0.67). However, when calibrated against the original model, the predicted number of events generated by the augmented version marginally over-estimated the true number observed.

CONCLUSIONS: The addition of a depression variable to the FRE equation improves the overall accuracy of the model for predicting 10-year CHD events in women, however may over-estimate the number of events that actually occur. This model now requires validation in larger samples as it could form a new CHD risk equation for women.

Technologies, such as Atomic Force Microscopy (AFM), have proven to be one of the most versatile research equipments in the field of nanotechnology by providing physical access to the materials at nanoscale. Working principles of AFM involve physical interaction with the sample at nanometre scale to estimate the topography of the sample surface. Size of the cantilever tip, within the range of few nanometres diameter, and inherent elasticity of the cantilever allow it to bend in response to the changes in the sample surface leading to accurate estimation of the sample topography. Despite the capabilities of the AFM, there is a lack of intuitive user interfaces that could allow interaction with the materials at nanoscale, analogous to the way we are accustomed to at macro level. To bridge this gap of intuitive interface design and development, a haptics interface is designed in conjunction with Bruker Nanos AFM. Interaction with the materials at nanoscale is characterised by estimating the forces experienced by the cantilever tip employing geometric deformation principles. Estimated forces are reflected to the user, in a controlled manner, through haptics interface. Established mathematical framework for force estimation can be adopted for AFM operations in air as well as in liquid mediums.

Critical reflection (CR) is at the core of postgraduate studies in c, and students from Asia in general, and from c in particular, often find the concept challenging when reading texts or applying it to written texts in English. This study reports on a case study of a Chinese postgraduate student in Australia. It explores the challenges and obstacles in terms of CR that she faced while completing her subjects in a TESOL program in Australia. These challenges were articulated in a semi-structured interview conducted with the student. Challenges include English language proficiency, lack of focus on writing in China where there is a lot of emphasis on memorisation, different systems of conceptualisation of topics in Chinese and English, and limited freedom of expression which is expressed as ‘authoritative’ control in the Chinese educational context.
