`I like football when it doesn`t hurt`: factors influencing participation in Auskick

Auskick is the Australian Football League's (AFL) introductory program specifically designed to recruit and harness the interest of primary or elementary school-aged children between the ages of 5-12 years. As an induction program, Auskick is underpinned by a philosophy that foregrounds involvement and enjoyment as foundational to a pathway to an ongoing affiliation with Australian Rules football. Getting young people to identify with Australian Rules football from early on is a strategic aspect of growing or sustaining the game. Within its charter of mass recruitment, Auskick is more about promoting an interest in football than it is about talent identification. Indeed, only a tiny minority of the more than 110,000 children that partake in the Auskick program in 2004 will go on to compete at the highest level. Drawing on over 200 interviews conducted with parents and children attending Auskick sessions, this paper presents an overview of some of the factors that influence initial participation in Australian Rules football. Among other things the authors ask participants how they intend to negotiate the behaviours and practices required to play a body contact sport like Australian Rules football.

Hope seen through the eyes of 10 Australian young people

Aim. The aim of this paper is to report the findings of a phenomenological study that explored hope in 10 young people in Australia.

Background. Evidence suggests many Australian young people are in crisis. Examination of key reports that detail the incidence of suicide, early drug-taking behaviours, homelessness, self-harm behaviours, joblessness, depressive disorders, crime statistics and alcohol abuse suggest that many of today's young people have lost resilience as well as vital connections to their community.

Method. Two methods were employed to encourage the participants to reflect on their experiences of hope – what it is and what it meant to them. The first was to supply participants with a disposable colour film camera and ask them to take pictures that, in their view, showed hope. The second was participation in an in-depth interview that was prompted in part, by their photographs. Interview audiotapes were transcribed verbatim and analysis of the text used the Turner method. The data were collected in 2002.

Findings. Four horizons of hope were revealed: at-one-with; a driving force; having choices; and connecting and being connected. These horizons are discussed, showing how, or if, the literature treats these dimensions of hope. Perspectives are offered on how they might be considered by nurses who are charged with caring for today's young people.

Conclusion. Registered Nurses who work with young people must understand the phenomenon of hope from their unique perspective before they can offer appropriate hope-facilitating strategies.

Grid-based method for ranking images with multiple objects

One of the content-based image retrieval techniques is the shape-based technique, which allows users to ask for objects similar in shape to a query object. Sajjanhar and Lu proposed a method for shape representation and similarity measure called the grid-based method [1]. They have shown that the method is effective for the retrieval of segmented objects based on shape. In this paper, we describe a system which uses the grid-based method for retrieval of images with multiple objects. We perform experiments on the prototype system to compare the performance of the grid-based method with the Fourier descriptors method [2]. Preliminary results have been presented.

Research or professional development?

Generally, teachers’ contact with academics tends to take two forms: either they are the ‘subjects’ of research which is done on or for them; or they are the recipients of professional development which is again done to or for them. In both cases the teachers are positioned in relatively passive and powerless relationships.

This paper describes a research project undertaken in 2002 wherein I explored the possibilities of constructing research as a collaborative project between academics and teachers. In this project I attempted to establish a relationship with teachers as co-researchers who conducted parts of the research process themselves, including data collection and analysis.

This paper explores the differences in perceptions of this research relationship and reflects on the contradictions in the statements made by the teachers during discussions on the benefits of the research project. These contradictory statements have led me to ask questions of myself as an academic and a researcher, and of the research process I designed. These questions are the focus for this paper and include: Was I engaging in ‘research as usual’ under the guise of engaging teachers in co-researcher practices? What kinds of discourses were operating in our discussions and how did these discourses work to position the teachers? How am I implicated in the construction of these positionings?

Should we save or should we consume? Linking growth theories and the Keynesian models

In major economic growth theories, high saving rate gives rise to high level of output per capita. But in Keynesian economics, high saving rate causes low consumption and will lead the economy into recession. Students may ask, "For the well-being of an economy, should we save or should we consume?" In most of the intermediate macroeconomics textbooks, economic growth and Keynesian economics are taught in separate chapters; and in many cases, these chapters are not even successive to each other. There lacks a continuity between the long run and short run models. This paper builds a bridge between growth theories and Keynesian models. It links the Solow diagram and the IS-LM curves and depicts the short run and long run implications of a change in the saving rate.

The questioning skills of clinical teachers and preceptors: a comparative study

Aim of the study. The purpose of this study, conducted as partial requirement for a Master of Nursing Studies Degree, was to explore, describe and compare the level of questions asked by clinical teachers and preceptors.

Background. Questioning is one of many teaching/learning strategies thought to facilitate the development of critical thinking skills which are integral to nursing practice. As such the type and number of questions asked have implications for student learning. Currently in Melbourne, Australia, many undergraduate nursing degree courses utilize both clinical teachers and preceptors to facilitate student learning in the clinical setting.

Design. A comparative descriptive design was used. Participants were given three acute care patient scenarios involving an undergraduate nursing student, as part of a questionnaire, and asked to identify the questions they would ask the student in relation to the scenario.

Findings. Data revealed that the clinical teachers had considerably more years of experience in their role and higher academic qualifications than did the preceptors. The clinical teachers also asked a greater number of questions overall and more from the higher cognitive level. Despite this, the findings suggest that both clinical teachers and especially preceptors need to increase the number of higher level questions they ask.

Conclusions. Based on the findings of this study, it is evident that there is a need for further comparative studies into the questioning skills of clinical teachers and preceptors. Also, these two groups require education about the importance of higher level questioning for student learning as well as how to ask questions generally.

Revisiting the impact of formative assessment opportunities in student learning

This project developed as a result of some inconclusive data from an investigation of whether a relationship existed between the use of formative assessment opportunities and performance, as measured by final grade. We were expecting to show our colleagues and students that use of formative assessment resources had the potential to improve performance of first year students. This first study, undertaken in semester 1 2002, indicated that there was no apparent relationship between the two, even though the students reported how useful they found the formative assessment resources. This led us to ask if there was a transition effect such that students were not yet working in an independent way and making full use of the resources, and/or whether in order to see an effect we needed to persuade non-users of the resources to become users, before investigating if use can be correlated with improvement in performance. With the 2002-3 NextEd ASCILITE Research Grant we set out to repeat our project and to look at use and usefulness of resources in both first and second semester, to encourage non-users to become users and to investigate the relationship between use and performance. Now our story has a different ending.

To save or to consume: linking growth theory with the Keynesian model

In the neoclassical growth theory, higher saving rate gives rise to higher output per capita. However, in the Keynesian model, higher saving rate causes lower consumption, which may lead to a recession. Students may ask, “Should we save or should we consume?” In most of the macroeconomics textbooks, economic growth and Keynesian economics are in separate, sometimes unsequential, chapters. The connection between the short run and the long run is not apparent. The author builds a bridge between the neoclassical growth theory and the Keynesian model. He links the Solow diagram and the IS-LM curves and depicts the short-run to long-run transition of the economy after changes in saving and other macroeconomic policies.

What makes a good investigative interviewer of children? A comparison of police officers' and experts; perceptions

Purpose – The purpose of this paper is to examine police officers’ perceptions about their role in interviewing children, and to compare these perceptions with those of child eyewitness memory experts.

Design/methodology/approach – A diverse sample of 23 police officers (from three states of Australia) individually participated in in-depth interviews where they were asked to define what makes a good interviewer in the area of child abuse investigation.

Findings – Irrespective of the background of the officers, the important role of interviewers’ personal attributes was emphasised (e.g. having a relaxed, empathetic, warm nature). Such personal attributes were more prominent in the participants’ descriptions than knowledge of legislation and children’s
development, prior job experience, and interviewing techniques.

Research limitations/implications – The paper shows that while child eyewitness memory experts acknowledge the importance of establishing a bond of mutual trust between the interviewer and the child, the importance of utilising an open-ended questioning style for enhancing rapport, and
for eliciting a detailed and accurate account of abuse cannot be overstated. The possible reasons for the police officers’ emphasis on personal qualities are discussed.

Originality/value – This paper has revealed that limitations in the competency of police officers in interviewing children is not merely a problem of “doing” (i.e. learning to ask open-ended questions),
but may also reflect ingrained attitudinal and organisational barriers.

Grounded theory as foundations for methods in applied ontology

Research into domain specific ontologies is difficult to treat empirically. This is because it is difficult to ground domain ontology while simultaneously being true to its guiding philosophy or theory. Further, ontology generation is often introspective and reflective or relies on experts for ontology generation. Even those relying on expert generation lack rigour and tend to be more ad-hoc. We ask how Grounded Theory can be used to generate domain specific ontologies where appropriate high level theory and suitable textual data sources are available. We are undertaking generation of a domain ontology for the discipline of information systems by applying the Grounded Theory method. Specifically we are using Roman Ingarden’s theory of scientific works to seed a coding family and adapting the method to ask relevant questions when analysing rich textual data. We have found that a guiding ontological theory, such as Ingarden’s, can be used to seed a coding family giving rise to a viable method for generating ontologies for research. This is significant because Grounded Theory may be one of the key methods for generating ontologies where substantial uniform quality text is available to the ontologist. We also present our partial analysis of information systems research.

RQF publication quality measures: methodoligical issues

The Research Quality Framework uses Thomson-ISI citation benchmarks as its main set of objective measures of research quality. The Thomson-ISI measures rely on identifying a core set of journals in which the major publications for a discipline are to be found. The core for a discipline is determined by applying a nontransparent process that is partly based on Bradford’s Law (1934). Yet Bradford was not seeking measures about quality of publications or journals. How valid then is it to base measures of publication quality on Bradford’s Law? We explore this by returning to Bradford’s Law and subsequent related research asking ‘what is Bradford’s Law really about?’ We go further, and ask ‘does Bradford’s Law apply in Information Systems?’ We use data from John Lamp’s internationally respected Index of Information Systems Journals to explore the latter question. We have found that Information Systems may have a core of journals only a subset of which is also in the list of Thomson-ISI journals. There remain many unanswered questions about the RQF metrics based on Thomson-ISI and their applicability to information systems.

Spectral kernels for classification

Spectral methods, as an unsupervised technique, have been used with success in data mining such as LSI in information retrieval, HITS and PageRank in Web search engines, and spectral clustering in machine learning. The essence of success in these applications is the spectral information that captures the semantics inherent in the large amount of data required during unsupervised learning. In this paper, we ask if spectral methods can also be used in supervised learning, e.g., classification. In an attempt to answer this question, our research reveals a novel kernel in which spectral clustering information can be easily exploited and extended to new incoming data during classification tasks. From our experimental results, the proposed Spectral Kernel has proved to speedup classification tasks without compromising accuracy.

Intranasal vaccination with proinsulin DNA induces regulatory CD4+ T cells that prevent experimental autoimmune diabetes

Insulin, an autoantigen in type 1 diabetes, when administered mucosally to diabetes-prone NOD mice induces regulatory T cells (T_reg) that protect against diabetes. Compared with protein, Ag encoded as DNA has potential advantages as a therapeutic agent. We found that intranasal vaccination of NOD mice with plasmid DNA encoding mouse proinsulin II-induced CD4⁺ T_reg that suppressed diabetes development, both after adoptive cotransfer with "diabetogenic" spleen cells and after transfer into NOD mice given cyclophosphamide to accelerate diabetes onset. In contrast to prototypic CD4⁺CD25⁺ T_reg, CD4⁺ T_reg induced by proinsulin DNA were both CD25⁺ and CD25^– and not defined by markers such as glucocorticoid-induced TNFR-related protein (GITR), CD103, or Foxp3. Intriguingly, despite induction of T_reg and reduced islet inflammation, diabetes incidence in proinsulin DNA-treated mice was unchanged. However, diabetes was prevented when DNA vaccination was performed under the cover of CD40 ligand blockade, known to prevent priming of CTL by mucosal Ag. Thus, intranasal vaccination with proinsulin DNA has therapeutic potential to prevent diabetes, as demonstrated by induction of protective T_reg, but further modifications are required to improve its efficacy, which could be compromised by concomitant induction of pathogenic immunity.

Minimising risks in IT outsourcing: choosing target services

This paper provides a risk-based framework for deciding on which IT services to outsource and which to keep in-house. This framework considers the probabilities both of negative outcomes, and of failing to achieve positive outcomes. The authors examine the major components of outsourcing risk and their drivers, and from this derive a series of questions decision-makers can ask when deciding what sourcing options to adopt for different services. The framework was developed on the basis of five years of qualitative and quantitative research into the experiences of organizations involved in outsourcing IT.
