Obesity prevention and public health

More than 22 million children under five are now obese or overweight. Globally, an estimated 10% of school-aged children, between five and 17 years old, are overweight or obese, and the situation is getting worse. Although recognised clinically for some time as an important condition that increases risk of ill-health in affected individuals, it is only recently, that obesity has been recognised as a population-wide problem that requires preventive action. Obesity is a major contributor to diseases and disability, the associated health costs are enormous, obesity has already reached epidemic proportions in many countries, and incidence is continuing to increase in children and adults. Disturbingly the epidemic is not confined to developed countries, with many developing countries and those in transition affected. While recognised as a major population health problem, our understanding of the causes of the epidemic is poor, there has been relatively little population-based research that has focused on the prevention of unhealthy weight gain, and as a consequence knowledge regarding how and where best to intervene is limited. This book draws together the existing literature and expertise and with a view to helping set the agenda for public health action. The book is divided into three sections. Part 1 provides an overview of the context of the problem. It examines the epidemiology of obesity, the role of behavioural factors, socio-cultural factors and environmental factors in the obesity epidemic. Part 2 reviews interventions across a range of key settings and in different population groups - drawing on existing research that has aimed to increase physical activity, promote healthy eating and prevent obesity at a population level. Given how little research there is that has specifically examined the effectiveness of interventions aimed at preventing obesity per se, Part 3 explores potential opportunities to prevent obesity

Using activity theory in researching young children's use of calculators

Constructivist and socio-cultural perspectives in mathematics education highlight the crucial role that activity plays in mathematical development and learning. Activity theory provides a socio-cultural lens to help analyse human behaviour, including that which occurs in classrooms. It provides a framework for co-ordinating constructivist and socio-cultural perspectives in mathematics learning. In this paper, we adopt Cole and Engeström's (1991) model of activity theory to examine the mediation offered by the calculator as a tool for creating and supporting learning processes of young children in the social environment of their classroom. By adopting this framework, data on young children's learning outcomes in number, when given free access to calculators, can be examined not only in terms of the mediating role of the calculator, but also within the broader context of the classroom community, the teachers' beliefs and intentions, and the classroom norms and the division of labour. Use of this model in a post hoc situation suggests that activity theory can play a significant role in the planning of future classroom research.

Environmental determinants of healthy eating : in need of theory and evidence

In order to promote healthful nutrition, insight is needed into the determinants of nutrition behaviours. Behavioural determinant research and behavioural nutrition interventions have focused mostly on individual-level motivational factors. It has been argued that the individual's socio-cultural and physical environments may be the main determinants of nutrition behaviours. However, the theoretical basis and empirical evidence for environmental determinants of nutrition behaviours are not strong. The present paper is a narrative review informed by a series of systematic reviews and recent original studies on associations between environmental factors and nutrition behaviours to provide an overview and discussion of the evidence for environmental correlates and predictors of nutrition behaviour. Although the number of studies on potential environmental determinants of nutrition behaviours has increased steeply over the last decades, they include only a few well-designed studies with validated measures and guided by sound theoretical frameworks. The preliminary evidence from the available systematic reviews indicates that socio-cultural environmental factors defining what is socially acceptable, desirable and appropriate to eat may be more important for healthful eating than physical environments that define the availability and accessibility of foods. It is concluded that there is a lack of well-designed studies on environmental determinants of healthful eating behaviours. Preliminary evidence indicates that social environmental factors may be more important than physical environmental factors for healthful eating. Better-designed studies are needed to further build evidence-based theory on environmental determinants to guide the development of interventions to promote healthful eating.

Rogue men and predatory women : female fan's perception of Australian footballers' sexual conduct

The 2004 Australian Football League and National Rugby League seasons started amidst claims made by women about players behaving inappropriately towards them. A raft of allegations surfaced in the media, prompting nationwide debate on the issue of sportsmen and violence. While sport sociologists have made important inroads toward understanding sexual misconduct by male athletes, much of this research appears to focus on the socio-cultural factors informing the perpetrators' actions. This study takes a different approach, analysing the perspectives of female Australian rules football fans to consider gendered narratives of sexual misconduct. Our findings demonstrate that discourses of individualism, along with a mix of socio-cultural and biological arguments, are used by women to reconcile players' misconduct with continuing support of their sport.

Regional trade agreements : performance evaluation and research agenda

This paper proposes a broad model for key success factors in Regional Trade Agreements (RTAs). Current literature is relatively limited in its focus on largely economic consequences of RTAs and the externalities are mostly ignored. This model incorporates five predictor dimensions forming the character of a RTA as follows: (1) Economic, (2) Socio-Cultural, (3) Negotiation, (4) Country Objectives and (5) Review process. It proposes a methodology for the empirical testing of the proposed model. The proposed model, potentially, facilitates the measurement of the character of a RTA and its association with various RTA objectives.

Whose risk? 'Managing' risk in school leadership

This article discusses the rise in prominence of 'risk' in schools and the processes and procedures it has triggered in its wake. The discussion commences with formal definitions of 'risk' and how risk is mandated and 'managed' in schools. Alternative views are canvassed and hegemonic emphases in risk policy and practice are critiqued. Taking a socio-cultural approach, the article explores risk from the perspective of school leaders, raising topics elided in risk discourses. The article takes the view that current conceptions of 'risk' have created greater complexity and further risks for the school leaders who 'manage' it. The article investigates school leaders 'and risk' - how risks emerge in the course of everyday school leadership work; school leaders 'at risk' - interrogating the personal and professional risk borne by school leaders through risk policies; and leaders 'as risk' - broaching the rarely raised topic of 'bad' leadership in schools, with its deleterious effects on individuals and whole school communities. These aspects of risk are not found in current literature on risk in educational leadership. The article then goes further to raise the 'undiscussable' topic of risky central leadership practices which render school leaders at even more risk. The article concludes with discussion of risks that school leaders cannot afford not to take in dealing with risk, particularly with regard to collective action to address mandated policy procedures which are detrimental to the foundational issues of teaching, learning, professional agency and community perceptions.

An explicit representational focus for teaching and learning about animals in the environment

There has been growing interest in linking the learning of Science with the literacies of Science and representations. Recent attention has been focused on learning theories that emphasise the socio-cultural and situated aspects of learning, and in particular the notion of learning as participation in a discourse community. This paper will describe a learning sequence planned wilh Year 5/6 teachers to study invertebrates in the schoolground environment, but with an additional focus in which students generated and negotiated representations, and discussed the adequacy of these. The paper will present data from video capture of classroom activities, students' work samples, and pre- and post-unit testing, to explore what a representational focus might entail in teaching science, and the role of representations in learning, reasoning and exploring in science.

The Pacific OPIC Project (Obesity Prevention In Communities) : action plans and interventions

Background: The Pacific OPIC Project (Obesity Prevention In Communities) includes whole-of-community intervention programs in four countries (Fiji, Tonga, New Zealand, Australia) aimed at reducing the prevalence of overweight and  obesity in youth.

Development of Action Plans: At each intervention site, preliminary interviews  were conducted with youth to identify the potential socio-cultural barriers and  facilitators to healthy eating and regular physical activity in order to attain and sustain a healthy body size. This and other information was presented at a 2-day workshop with community stakeholders, including youth. The participants then prioritised the components for a draft action plan which was later consolidated through further community consultation.

Action Plan objectives: Each action plan had two overall aims: to build  community capacity and to promote healthy weight. The first three objectives in each action plan were on capacity building, social marketing messages, and evaluation. Next were a set of four to five behavioural objectives with associated strategies involving programs, events, social marketing and environmental  change. Lastly, each site had one or two innovative or developmental objectives.

Progress: Interventions began in all sites from 2005, with the action plans guiding implementation priorities. The initial behavioural objective for targeting in Fiji was eating regular breakfast and meals throughout the day, for Tonga it was physical activity, and for Australia and New Zealand it was increasing water consumption and decreasing consumption of sweet drinks.

Conclusions: The action plans have provided the basis for community engagement in the project, the guide to the implementation of activities and the template for the evaluation plan.

Different sounds, different musics, different teaching : an Australian case study in multicultural teaching and learning

This single case study is part of a wider ongoing research project, begun in 2005, entitled Intercultural attitudes of pre-service music education students from Deakin University and Monash University, Melbourne, Australia. One participant selected from the entire cohort and reinterviewed in 2009 as it was apparent that his experience and expertise outstripped all the others. This paper explores the tensions between authentic pedagogical practice, as understood by the interviewee, in community teaching and in a school. The data generated were analysed using interpretative phenomenological analysis. Three major themes were identified: benefits of community music making, authentic learning, and reality of class music practice. The data demonstrate that authentic socio-cultural understanding is achievable in community music teaching, particularly in the honoring of what individuals bring the sharing of expertise between ensemble players and valuing community arts practice. However, as this is a case study demonstrates, at least in some schools, there is a lack of understanding of how multicultural music could and should be taught. Australian schools should encourage teachers who bring different sounds, different musics and different teaching into the classroom thus resolving to some degree, the potential mismatches between culturally developed learning styles and music teaching methods.

Science education in early childhood : a snapshot of Australian settings

In Australia, reform is occurring in the area of early childhood. It is in this time of reform, that a research project was instigated which studied the amount of science being undertaken in early childhood settings as well as how it was implemented. This highlighted some interesting differences across settings. This presentation will describe case studies of four pre-school settings and some of the activities undertaken by the children - both as part of the formal program and through incidental play. It will consider these through a socio-cultural framework, noting how teachers used their understandings of play and play theory, to enhance children’s understandings.

Science professional development for early childhood educators : some identified issues

In a small research project, using a qualitative approach we surveyed eleven pre-school teachers/coordinators asking them for information about the science experiences within their EC setting. We identified the opportunities they had for science professional development and clarified the level of their qualifications and those of a further 22 staff. In addition, we conducted four case studies to interrogate this further, and interviewed four early childhood educators asking for more detail about the science they provided and about their comfort in teaching science. The interviews revealed that although early childhood educators indicated that they provided a large number of varied experiences, often they were unsure of the science content or the science understanding. This limited their abilities to develop the activities further. Early childhood educators also indicated that whilst there was access to some science professional development, more would be welcome. The types of professional development which they felt would be most beneficial were "hands-on" play experiences - a "quick fix" approach. This presentation will discuss the findings of the research through a socio-cultural framework, noting some of the issues being raised in our discussions with the educators.

External public piano examinations in Malaysia : social and symbolic significance

The thesis investigated the social and symbolic significance of acquiring a 'music education' through the taking of piano tuition and external public music examinations. It aimed to discover why the learning of the piano and the certification of musical attainment are so prevalent and revered among Malaysian music students. Its purpose was to unravel the socio-cultural raison d'etre of this approach to music education through the creation of a metatheoretical schema, which is premised upon the theories of symbolic interactionist, George Herbert Mead, music analyst, Heinrich Schenker and social theorist, George Ritzer. Central to the argument in this instance is the symbolic significance associated with the act of playing the piano. The investigation attempted to determine if this 'act' conveyed a symbolic meaning that is peculiar to a specific cultural vista. It further examined the degree to which this practice represented both a validation and a sense of conformity to social norms in the continuity and stability of an expanding middle class society in Malaysia. The Associated Board of the Royal Schools of Music (ABRSM) is the largest of the five main external public music examination boards that operate in Malaysia. Since 1948, over one million candidates have enrolled for ABRSM examinations in Malaysia and a team of approximately thirty ABRSM examiners visit Malaysia for three months every year. The majority of the candidates are pianists. Given such large numbers of piano candidates, one might expect a healthy development of musical talent in the country with aspiring pianists eager to demonstrate their musical prowess. However, this does not seem to be the case. On the contrary, there appears to be a curious lacuna between the growing number of students who enrol for external public music examinations and the seemingly lack of interest in public music making and the honing of general musicianship skills. The thesis hence examined the symbolic meaning of this socio-musicological phenomena.

Teenage technological experts : Bourdieu and the performance of expertise

This thesis explores the construction of technological expertise amongst a heterogenous group of New Zealand teenagers, specifically in regard to their home computer use, which for many of them is their primary site of leisure. This thesis explores the field in which these teenagers are positioned, and explains the practice constituting that field. In this field, the trajectories towards expertise are explained including the time, experimentation, and pleasure evident in their praxis. The qualitative study involved observations and interviews with eight teenagers aged 13 – 17. Five boys and three girls participated and each attended one of various secondary schools located within a provincial city in New Zealand. All of the participants considered themselves to be technological experts, and their peers and/or their family supported this comprehension. Drawing on Pierre Bourdieu’s socio-cultural theories, the capital (cultural, economic, social) and habitus of the teenagers are described (habitus being what makes them who they are, and continues to define who they are in the future). Chapter five centres on explaining the field the teenagers have positioned themselves in, namely the field of out-of-school leisure and home computer use. It also explores the construction and performance of technological expertise within the field. Chapter six examines traditional views of schooling and expertise, and contrasts these views with what the teenagers think about their learning and expertise. This gap is specifically explained with regard to differences between the concepts and value of learning, expertise, and technology, and how they are recognised and valued differently between generations. Chapter seven explores the praxis that the participants exhibit, which is arguably misrecognized by those whose interests are in the established order (e.g. institutional, societal structures). The field they are placed in is arguably part of the broader field of education, yet the findings suggest their capital is misrecognized by digital newcomers, and therefore not legitimated. This thesis concludes that the gap between teenager and adult understandings of expertise is exacerbated in the digital world in which the teenagers position themselves. Their schooling is mainly positioned in the print culture of previous generations and consequently, in the lives of these teenagers, schooling has had little influence on the development of their technological expertise. Additionally, gender has had little impact in their development of expertise; therefore stereotypical notions of female underachievement as computer experts are contested.

Impact of the extended family on microenterprise growth in Ghana : a case study of Accra

This study examines the extended family's impact on microenterprise growth at the individual level, where microenterprise operators have some control over constraints affecting their operations. Beyond the individual level, microenterprise operators have little control over constraints such as government policies and regulations, competition from import-substitution industries and exploitation by corrupt officials. Therefore, it is at the individual level that the extended family serves as a crucial parameter of microenterprise growth and the success with which MEs graduate from the informal sector into the mainstreams of small business. Within this domain, this author has examined the extended family and found that there is a need for policy makers and MED administrators to adopt a more culturally sensitive approach to microenterprise growth if the extended family is to be engaged as a partner in their efforts to support microenterprises as a source of income and employment generation, A central question posed is why most writers on microenterprise activities in Ghana have neglected the extended family as a factor that should be considered in the design of microenterprise growth strategies and policies? The answer to this question was explored in the process of data gathering for this thesis and the results are presented here, especially in chapter 3 below. Suffice it to note here that this neglect has many roots, not least of which is the proclivity of mainstream economics, modern administration practice and the objectivity of double entry accounting based documentation procedures to focus on measurable growth in the formal sectors of the economy and structural constraints such as the lack of finance, lack of market demand, lack of access to technology and government regulations. Consequently, a noticeable trend among these writers is that they rightly advocate finance be made accessible to microenterprises, however, few question whether the finance is effectively used towards microenterprise growth. This issue is crucial in the face of evidence from this study which shows that finance accessed towards microenterprise growth is often put to other uses that negate growth thus keeping microenterprises within the bounds of the informal sector as against graduating out of the informal sector. As a result, these writers have neglected the intimate relations between the extended family and microenterprises, and most importantly, the constraint that the extended family inflicts on microenterprise growth at the individual level of activity. This study, by targeting the growth of the individual microenterprise in the socio-cultural context in which this growth must be achieved, has highlighted the constraint that the extended family does pose on MED. However, the study also shows that these constraints are important not because there is anything inherently wrong with the extended family, but because the socio-economic and policy environment is not consistent with the positive role that the extended family can and should play in the graduation of microenterprises from the informal to the formal sector of the economy in Ghana.

How do teachers investigate scientific concepts in an Early Childhood Environment?

Early Childhood Educators have an important role to fulfil in aiding children's development and understandings in the science curriculum. There are many different views and opinions on how science can be taught in an Early Childhood environment, it is therefore our aim to investigate how teachers feel about teaching science concepts and promoting science in the early childhood centre. We aim to discover how everyday activities relate to the nature of science within our everyday lives. The science curriculum is important in Early Childhood settings as it provides children with various opportunities to explore the natural world. We are hoping to gain a deeper understanding of how teachers are guiding and encouraging children to make sense of their experiences. It is also important that we explore how Early Childhood Educators understand their own practice in teaching science concepts in their curriculum.

Description of project: We will be completing a small inquiry based task which will require us to compile data collected from interviews, recordings from teachers in long day and kindergarten settings around the Geelong region.

Methodology: ln order to undertake this research we will be using a socio cultural framework, focusing on language in the social environment and play (basing our ideas on the theories of Vygotsky). We will be undertaking narrative accounts to obtain data which will be collated from three different sources.

Ethical implications of projects: We do not foresee any significant risks to any participant in this study. The topic of the research is uncontroversial, and we will be taking measures to ensure anonymity or confidentiality where appropriate.
