Continuous improvement through shared understanding : reconceptualising instructional design for online learning

Many Australian tertiary institutions provide support for academic staff in the design and development of online teaching and learning resources, often employing a centralised unit staffed with educational and instructional designers, multimedia and online developers, audio/video producers and graphic artists. It is not unusual for these units to have evolved from print-based distance education providers and consequently the design and development processes inherent within those units are often steeped in ‘traditional’ sequential instructional development models. We argue that these models are no longer valid for effectively working with academic staff given the dynamic nature of online learning environments and the diversity of skills to implement effective online learning. This paper therefore presents an extended instructional design model in which the development cycle for online teaching and learning materials uses a scaffolding strategy in order to cater for learner-centred activities and to maximise scarce developer and academic resources. The model also integrates accepted phases of the instructional development process to provide guidelines for the disposition of staff and to more accurately reflect the creation of resources as learning design rather than instructional design. It is a model that builds on instructional design processes and integrates concepts of team-based development, shared understanding and the development of relevant communities of practice.

Being on the edge of a shipwreck in planning decision-making: design as an anchor and future maker

This paper investigates recent attempts to Masterplan tourism planning and landscape development of the town of Port Campbell based on the concept of community-driven tourism planning. The Masterplan process generally sought to upgrade tourism facilities and to re-plan a core part of the Great Ocean Road corridor the proposed scheme little engendered community confidence nor encouraged the use of local community public resources of the Masterplan proposed outcomes. While analyzing broad range of aspects of the township and the national park, this design thesis attempted to identify the possible initiatives and landscape development models and also applied landscape narrative theory to focus on tourism experience making and landscape with layers of content embedded such as local history, environmental stories that would enrich the experience. The need for this paper is to articulate an alternate and more robust approach to designing on the fragile coastal edge whilst engendering community engagement and ensuring their aspirations are addressed. It is main contribution is both offering an alternate process but also demonstrating the use of design as a vehicle to reach this outcome. The research gap addressed is to challenge a conventional planning practice that was very much constrained by upper-level Melbourne-based parochial and managerial imperatives than lower-level community aspirations and perspectives.

Development of material models to predict the crashworthiness of tubes

Metallic tubes have been extensively studied for their crashworthiness as they closely resemble automotive crash rails. Recently, the demand to produce light weight yet safer vehicles has led to the need to understand the behaviour of novel materials such as composites, metallic foams and sandwich structures durign a crash. This paper presents a method to predict the crashworthiness of structural components using material modes. The material factors that most affect the crushing response are determined and quantified by developing and validating the crushing of a square tube model in Abaqus. The inputs from the model are used to construct a simple, physically realistic constitutive model and new test methods for predicting the material behaviour at high strain rates using low test speeds. These material models enable a designer to predict the crash behaviour of a structure without the need to perform extensive physical tests, thus reducing the time and cost of development.

Biological models of mental illness: implications for therapy development

Systems approaches are needed to recognise the complexity of the biological bases of psychiatric disease.

New approaches to gene discovery with animal models of obesity and diabetes

DNA-based approaches to the discovery of genes contributing to the development of type 2 diabetes have not been very successful despite substantial investments of time and money. The multiple gene-gene and gene-environment interactions that influence the development of type 2 diabetes mean that DNA approaches are not the ideal tool for defining the etiology of this complex disease. Gene expression-based technologies may prove to be a more rewarding strategy to identify diabetes candidate genes. There are a number of RNA-based technologies available to identify genes that are differentially expressed in various tissues in type 2 diabetes. These include differential display polymerase chain reaction (ddPCR), suppression subtractive hybridization (SSH), and cDNA microarrays. The power of new technologies to detect differential gene expression is ideally suited to studies utilizing appropriate animal models of human disease. We have shown that the gene expression approach, in combination with an excellent animal model such as the Israeli sand rat (Psammomys obesus), can provide novel genes and pathways that may be important in the disease process and provide novel therapeutic approaches. This paper will describe a new gene discovery, beacon, a novel gene linked with energy intake. As the functional characterization of novel genes discovered in our laboratory using this approach continues, it is anticipated that we will soon be able to compile a definitive list of genes that are important in the development of obesity and type 2 diabetes.

The impetus for the development of hospital in the home (HITH) programs: a literature review

Alternative health care delivery models such as Hospital in the Home (HITH) are proliferating in Australia and in most Western countries. Such models facilitate patients who would otherwise be hospitalised to be cared for in their own homes. This paper reports a review of the literature related to the development of HITH programs. It reveals that the driving force behind the implementation of acute care programs comes from political and managerial aims to reduce health care spending. Home is clearly an appropriate care option for certain acute patients however, there is no strong evidence to suggest that it suits everyone. Very little attention has been given to the patient's experience of home care and the ethical and social consequences are largely ignored.

Rural women and local economic development in south-west Victoria

In the 1990s, the appearance of women in leadership roles in local economic development organisations in small south-west Victorian towns heralded a change in gender relations in rural Australia. This paper contributes to an understanding of this process by investigating the actions and motives of women in leadership roles in small rural towns in south-west Victoria. The paper begins by establishing a framework of analysis based upon a notion of ‘paradigms in progress’. The argument is that in an increasingly interconnected world broader economic, social and political concerns encroach upon local cultures. In this process, older social paradigms or popularly accepted models for how the world works are either transformed, discarded or replaced on different levels. The different levels to which this paper refers are the macromodels of patriarchy, the mesomodels of economic development and the micromodels of leadership. It is the way that these levels intersect and how they are being changed that informs the explanation of women and leadership in south-west Victoria. The paper applies this framework to an analysis of interviews with 15 women in small towns in south-west Victoria. The paper concludes that women in the south-west have been able both to feminise the politics of local economic development as well as reposition the feminine in local social discourses.

Predicting IHRM strategy and practice decisions : development of the IHRM orientation typology

International human resource management (IHRM) is becoming increasingly fundamental to organisational success, as globalisation forces demand organisations to design and implement a global strategy. One of the most critical choices faced by IHRM practitioners is whether and when an organisation should adapt its human resource policies and practices to the local context (localisation). A typology of International Human Resource Management Orientations (IHRMO) that clarifies what IHRMO’s are and what they entail is developed from a review of the literature on localisation and globalisation, convergence and divergence and Perlmutter’s management typology. Additionally, two theoretical models are developed that predict which IHRM orientation identified in the typology should be adopted. The article takes a step towards elucidating effective IHRM strategy and practice decision-making by showing that culture and institutional pressures, amongst other tings, do make a difference.

Harnessing zebrafish for the study of white blood cell development and its perturbation

Considerable progress has been made in understanding the molecular basis of normal white blood cell development and its perturbation in disease through the use of clinical studies and traditional animal and cell line models. Despite this, however, many questions are still being answered and white blood cell disorders, including leukemia and lymphoma, remain a significant health problem. The zebrafish (Danio rerio) has emerged as a powerful alternative vertebrate model for the study of development and disease. We review the recent application of zebrafish to the study of white blood cell development and its disruption, particularly leukemogenesis. Such studies have highlighted the overall conservation of these processes throughout vertebrates, and establish zebrafish as a useful experimental model. This organism is now poised to make an important contribution to our understanding of the underlying genetic control of white blood cell development and its disruption, as well as the identification of new therapeutic agents.
