Are oil shocks permanent or temporary? panel data evidence from crude oil and NGL production in 60 countries

This paper examines the unit root properties of crude oil production for 60 countries employing a range of panel data unit root tests for the period 1971 to 2003. The study first employs a number of panel data tests that do not accommodate structural breaks and then proceeds to apply the Lagrange Multiplier (LM) panel unit root test with one structural break. The results of the panel data tests without a structural break are inconclusive with at best mixed support for joint stationarity. The findings from the LM panel unit root test with a structural break, however, are conclusive, suggesting that for a world panel and smaller regional-based panels, crude oil and NGL production are jointly stationary.

Nutrition and mental health research in Australia and New Zealand: A review of progress and directions for the future

This review summarises nutrition and mental health research in Australia and New Zealand between 1986 and 2006. The method used to identify papers for inclusion was a search of computerised databases: Medline, Cinahl and Meditext 1986–2006, with subsequent bibliographical review. Key search words were nutrition, diet, mental disorder, mental illness, weight, physical health, Australia and New Zealand. Inclusion criteria included: English language, original data in peer reviewed journals, and examination of some component of nutrition in people with a mental illness. The review of thirteen papers found that the evidence base for dietetic practice in mental health has developed through small assessment and interventional research, often with multidisciplinary collaboration. Future research should include quality and outcome measures with intersectoral partnerships. Dietitians are well positioned to lead and participate in mental health research and to implement research findings to improve the nutritional status of this vulnerable group.

Traversing theory and transgressing academic discourses : arts-based research in teacher education

Pre-service teacher education is marked by linear and sequential programming which offers a plethora of strategies and methods (Cochran-Smith & Zeichner, 2005; Darling Hammond & Bransford, 2005; Grant & Zeichner, 1997). This paper emerges from a three year study within a core education subject in preservice teacher education in Australia. This ‘practitioner’ research (Zeichner, 1999) engaged the problematics of authentic and meaningful learner-centred teaching and learning through an arts-based curriculum. Over the period of the study, two hundred and eighty pre-service teachers participated in a ‘dialogical performance’ (Conquergood, 2003) of pedagogy about curriculum and assessment through the construction of art about curriculum and assessment. The possibilities of an arts-based pedagogy in pre-service education were affirmed by the research. An enacted epistemological move by the teacher educators led to similar shifts by the students. This opened a space for the reappearance of learner through engagements with identities, positionings and agency. This was an act of ‘putting theory to work’ (Lather, 2006, 2007) and invoked transgressive practices of academic discourses.

The non-verbal and the verbal: expanding awareness of practice-led research in creative writings

This paper takes up the concept of practice-led research: research (or the production and performance of knowledge) that is implicit within practice – in this case creative arts practice and more specifically, creative writing practice. Does practice-led research offer new possibilities for recognition of contributions to research by writers? This exploration of creative practice and research stretches out tendrils between creative writing and other art forms. What may the predominantly non-verbal creative arts disciplines offer creative writing in terms of exploring modes of knowledge production and performance?

Responsible entrepreneurship in developing countries : understanding the realities and complexities

Developing countries have recently experienced a burgeoning of small-scale individual entrepreneurs (SIEs) – who range from petty traders to personal service workers like small street vendors, barbers and owners of small shops – as a result of market-based reforms, rapid urbanisation, unemployment, landlessness and poverty. While SIEs form a major part of the informal workforce in developing countries and contribute significantly to economic growth, their potential is being undermined when they engage in irresponsible and deceptive business practices such as overpricing, sale of underweight or substandard products, or attempts to hoard goods, to name a few. Despite the growing interest in corporate social responsibility (CSR) initiatives of small businesses in developing countries, the SIEs have received almost no attention. To address this void in the literature, we explore the reasons for the less than optimal level of social responsibility demonstrated by some SIEs in developing countries. We do so by drawing upon the existing literature to develop a comprehensive framework of social responsibility of SIEs highlighting their unique characteristics and the different contextual factors that they encounter in developing countries. Based on this framework, we then present a set of propositions specifying the influence of these contextual factors such as business environment, cultural traditions, socio-economic conditions, and both international and domestic pressures on the business practices of SIEs. The framework offers an explanation for the lack of responsible entrepreneurship of SIEs and has important implications for promoting sustainable business practices in developing countries where businesses are striving hard to survive and compete.

Towards a set of priorities for bird conservation and research in Australia : the perceptions of ornithologists

Australian delegates at the Australasian Ornithological Conference (2007) were surveyed by questionnaire to determine their perceived research and conservation priorities for Australian birds (n = 134). Respondents were honours or postgraduate students (37.4%), academics (26.2%), wildlife managers (6.5%), land managers (6.5%), environmental consultants (5.6%), independent wildlife researchers (5.6%) or had ‘other’ occupations not relevant to birds or their management (12.1%). Respondents rated their priorities on a predetermined set of issues, and were invited to add additional priorities. ‘Conservation of threatened species’ was considered the highest priority, followed by ‘Conservation of birds and biodiversity in general’, ‘Monitoring’, ‘Management’ and ‘Working with communities’. ‘Animal welfare/rights’ was regarded as comparatively less important. Eight of 11 conservation strategies were regarded as of high importance, these included habitat protection and rehabilitation, threat abatement, research, advocacy and education. This study documents the view of the ornithological community with respect to priority issues facing birds and could potentially feed into government and other policies aimed at conserving and understanding Australia’s birds.

Putting "space" on the agenda of sociocultural research in education

The global rescaling of the world, culture, and education has influenced how people experience their situationality, meaning-making, and learning in relation to the Other. This article explores the implications of spatial analysis for rethinking education in new conditions of cultural complexity. The experience of living and learning with difference is conceptualized as an open journey in which the very act of movement across spatial boundaries unlocks the fixity of meanings and identities and, hence, problematizes the spatial logic of bounded learning places. Explicating the tension between fixity and mobility, boundedness and flows, this article deploys the concepts of cultural-semiotic space, scale, and boundary to theorize locations of learning and meaning-making in new times.

Nano related research in fibres and textiles

With the increasing hype surrounding what nanotechnology can actually deliver, research emphasis in this area needs to be placed on how nanotechnology can bring tangible benefits to existing industries and ordinary consumers. This paper gives selected examples of real world applications of nano-structured materials, including nano fibrous and particulate materials. It reviews recent research into nano-structured surface coating of textile substrates for enhanced functionalities, and the development of fine and uniform nanofibres for advanced applications. Emphasis has been placed on relevant research activities in the Centre for Material and Fibre Innovation at Deakin University, Australia. In the nano-structured surface coating area, several examples of enhancing fabric performance and functionality are provided, including silica coating for photochromic textiles, superhydrophobic surface coating and transparent ZnO coating to reduce colour fading of textiles exposed to UV radiation. In the nanofibre area, these activities include: elimination of beaded fibres without increasing the average diameter of the electrospun nanofibres, electrospinning of side-by-side bi-component nanofibres, new insight into the evolution of fibre morphology in electrospinning and the electrospinning technology itself.

Electricity consumption in G7 countries : a panel cointegration analysis of residential demand elasticities

This article applies recently developed panel unit root and panel cointegration techniques to estimate the long-run and short-run income and price elasticities for residential demand for electricity in G7 countries. The panel results indicate that in the long-run residential demand for electricity is price elastic and income inelastic. The study concludes that from an environmental perspective there is potential to use pricing policies in the G7 countries to curtail residential electricity demand, and thus curb carbon emissions, in the long run.
