True and apparent scaling : the proximity of the Markov-switching multifractal model to long-range dependence

In this paper, we consider daily financial data of a collection of different stock market indices, exchange rates, and interest rates, and we analyze their multi-scaling properties by estimating a simple specification of the Markov-switching multifractal (MSM) model. In order to see how well the estimated model captures the temporal dependence of the data, we estimate and compare the scaling exponents H(q) (for q=1,2) for both empirical data and simulated data of the MSM model. In most cases the multifractal model appears to generate ‘apparent’ long memory in agreement with the empirical scaling laws.

Matching training needs and opportunities : the case for training brokers in the Australian agricultural sector

Lifelong learning has been linked by policymakers to economic and social wellbeing. This paper introduces the concept of training brokerage as an efficient way of meeting the needs of learners, industry and education and training providers. It presents findings from a study of the features, processes and outcomes of training brokerage arrangements within the Australian agricultural and natural resource management sectors. The purpose of the study was to identify and promote effective brokerage arrangements and models. The study used multi-method, multi-site techniques, comprising a telephone survey, case studies of good broking practice and stakeholder participation through workshops and a reference group. Training brokers act as facilitators or intermediaries in identifying and matching training needs and opportunities. They have close links with industry, and extensive networks that include reputable training providers. Brokers work with others to identify training needs and engage participants, and to identify, negotiate and plan appropriate training. Evaluation and further training are a key part of the process. Effective broking activity is underpinned by a series of ten generic principles. Brokerage has implications for the agricultural sector in developed and developing countries, in terms of improving the match of training provision to training needs, communication, coordination and collaboration across regions and industries. It also has broader implications for facilitating participation in client-driven lifelong learning, particularly for disenfranchised learners.

Interactional infrastructure in rural communities : matching training needs and provision

This paper reports some of the main lessons learnt from a collaborative project titled Generating jobs in regional Tasmania: a social capital approach investigating how two small rural Tasmanian communities could better match local training needs with training provision. The project was conducted within the context of the wider social, economic and demographic changes affecting the two rural communities and their ongoing efforts to manage such change. The paper provides a profile of the two communities with particular attention to their local education, training and employment infrastructure. Three research questions in terms of improving the contributions of leadership, partnerships and social capital are addressed. Development and utilisation of social capital, particularly in the form of interactional infrastructure (defined as opportunities and structures for interaction in a community) that brought together the range of stakeholders, appeared the key to successfully matching needs with provision.

Occupational health needs of universities : a review with an emphasis on the United Kingdom

This study describes the needs of universities in relation to planning the provision of occupational health services, by detailing their occupational hazards and risks and other relevant factors. The paper presents the results of (1) an enquiry into publicly available data relevant to occupational health in the university sector in the United Kingdom, (2) a literature review on occupational health provision in universities, and (3) selected results from a survey of university occupational health services in the UK. Although the enquiry and survey, but not the literature review, were restricted to the UK, the authors consider that the results are relevant to other countries because of the broad similarities of the university sector between countries. These three approaches showed that the university sector is large, with a notably wide range of occupational hazards, and other significant factors which must be considered in planning occupational health provision for individual universities or for the sector as a whole.

Apparent in vivo Δ-6 desaturase activity, efficiency, and affinity are affected by total dietary C18 PUFA in the freshwater fish Murray cod

Dietary fatty acids are known to modulate fatty acid metabolism in fish. However, the innate capability of fish to bioconvert short chain fatty acids to health promoting long chain fatty acids (LCPUFA) is insufficient to compensate for a reduced dietary intake. While many studies have focused on the dietary regulation of the fatty acid bioconversion pathways, there is little known regarding the effects of the dietary levels of C18 polyunsaturated fatty acids (PUFA) on fatty acid metabolism. Here, we show a greater degree of apparent enzyme activity (Δ-6 desaturase) in fish fed a diet with higher amounts of dietary C18 PUFA. In particular, fish receiving high amounts of dietary C18 PUFA had a greater amount of Δ-6 desaturase activity acting on 18:3n-3 than 18:2n-6. However, with the gradual reduction of dietary C18 PUFA there was a shift in substrate preference of Δ-6 desaturase from 18:3n-3 to 18:2n-6. This information will provide valuable insight for the implementation of low fish oil diets, which permit the maintenance of n-3 LCPUFA levels in farmed Murray cod.

Capital works procurement policies in Australia : implications for understanding and meeting client needs

This paper undertakes a case study of procurement through a comparative analysis of the capital works procurement policies of the Commonwealth, State, and Territory Governments in Australia. Capital works procurement policies provide the mechanism by which governments manage procurement processes, and frame how individual government agencies, as clients, participate in those processes. The paper proposes a typology of capital works procurement approaches, together with implications of how these different policies play out for clients. A tentative proposition is advanced that policy approaches to capital works procurement either explicitly or implicitly, make assumptions about the organisational capability of clients to plan and deliver capital works projects, including their ability to understand and articulate their own building needs. Additionally, the paper concludes that innovation has occurred at a policy level in capital works procurement. Recommendations for further research are suggested.

Mathematical power of special-needs pupils : an ICT-based dynamic assessment format to reveal weak pupils' learning potential

This paper reports a study aimed at revealing special-educational-needs pupils' learning potential by means of an ICT-based assessment including a dynamic visual tool that might help pupils when solving mathematics problems. The study focused on subtraction problems up to 100, which require 'borrowing'. These problems, in which the value of the ones-digit of the subtrahend is larger than the ones-digit of the minuend, are known as a serious difficulty for weak pupils in mathematics. Seven of such problems from a standardised test were placed in the ICT environment. Data were collected from two test conditions: the standardised written test format and the ICT version of the test items including the tool that provided pupils with a set of virtual manipulatives. The 37 pupils involved in the study were 8–12 years old and from two special-education schools in the Netherlands. Comparison of the performance scores in the two formats showed that an ICT-based assessment format, including a dynamic visual tool, can reveal weak pupils' learning potential and strategy use. The study also pointed out that 'partial-tool use', ie, not carrying out the complete subtraction operation with the tool, can provide sufficient support to find the correct answer.

The education and information needs of young adults with type 2 diabetes : a qualitative study

Aims and objectives. To identify the preferred content and delivery mode of education information for people aged 25 to 45 with type 2 diabetes to enable them to effectively self-manage their diabetes.

Background. People with type 2 diabetes are required to manage their own health and initiate behavioural changes. Self-management education and resources have typically been targeted at people aged 50 years and older. Little is known about the concerns and needs of younger people in managing type 2 diabetes, which are likely to be different from those of older people.

Design. A qualitative design was considered the most appropriate to elicit participants' views and perceptions of their type 2 diabetes information needs.

Methods. Data were obtained from one focus group (n = 9) and telephone interviews (n = 4) with people aged 25 to 45 with type 2 diabetes conducted in 2008.

Results. Implicit in participants' responses was their need to be active partners in managing their diabetes. Participants wanted information that is easy to understand, brief, consistent, age-specific and about a number of topics that are not adequately covered at present. They wanted a centralised source of information and a range of delivery mode options. Participants expressed some ambivalence about the Internet as a source of information. Participants also wanted age-specific group sessions, support from peers, psychological support, increased understanding of type 2 diabetes in the community, and a focus on preventing diabetes.

Conclusions. Young people with type 2 diabetes have specific diabetes needs and preferred information delivery modes. Participants felt current diabetes education programs do not cater specifically to their age group. Education and information resources need to be developed for the target group, addressing their content and format preferences.

Relevance to clinical practice. Health professionals need to utilise appropriate delivery modes and include information relevant to younger people when providing education information to young adults with type 2 diabetes.

Support needs of parents of sick and/or preterm infants admitted to a neonatal unit

The sudden unexpected delivery of a preterm infant elicits many emotional responses from parents, with studies confirming the importance of providing parents with nursing support. The purpose of this study was to measure parents' perception of the type and level of support that nurses provided in an Australian neonatal unit, and to determine the extent to which parents were satisfied with the support currently provided. A convenience sample of 112 parents in an Australian tertiary neonatal unit were invited to complete the nurse parent support tool (NPST), which is a 21-item questionnaire used to measure the level of nursing support. The NPST consists of four domains -emotional, informational, appraisal and instrumental support. A second tool was used to assess parent satisfaction with nurse-to-parent support. A total of 62 parents completed the NPST and satisfaction tool.

Results showed that instrumental support had the highest mean score for both nurse-to-parent support 4.51 (out of 5) and 4.36 for satisfaction. The mean score for nursing support was 4.21 followed by satisfaction with nurse-to-parent support at 4.16. In contrast, emotional support had the lowest mean score for both nurse-to-parent support at 3.94 and 3.97 for satisfaction. Parents indicated that they needed further support with lactation, breastfeeding and assistance with parenting skills. Overall, results indicated that parent perception of nursing support was positive and that parents were highly satisfied with the nursing support provided in the neonatal unit. However, some attention needs to be given to providing more support and information on breastfeeding and parenting skills.

Music needs no visa : insights from three South African voices on teaching African music in Melbourne, Australia

As Australia becomes increasingly multicultural, there are many that would argue that the teaching and learning of music at educational settings can be carried out in a number of ways where cultural context and authenticity is imperative. This paper discusses the main arguments of teaching and learning in music education and provides some theoretical perspectives of teaching African music as groundwork for the discussion and findings. This paper is part of a wider study called 'Smaller steps in longer journeys' and. provides insight into the teaching of South African music in Melbourne. Three South African voices (my own as tertiary music educator, an artist in schools and a primary music specialist) through reflection and interview data considers 'how' and 'why' African music is taught The discussion presents an openmindedness of music when it travels to a new country where the pedagogy is the process of production and exchange, a social-discursive practice whereby process and understanding is more important than just product. As music requires no visa it will continue to travel and be shared in different context where pedagogical practice considers teacher, learner and knowledge.
