    This paper presents the results of a project that considered how research might best contribute to Aboriginal and Torres Strait Islander health and wellbeing in the year 2030. Executive summary In late 2012, the Lowitja Institute embarked on a project using ‘futures thinking’ to consider how research might best contribute to Aboriginal and Torres Strait Islander health and wellbeing in the year 2030. The project was motivated by a desire to ‘get ahead of the game’: to anticipate and prepare for the potential research demands of the future. In particular, there was a desire to ‘close the gap’ between the point at which important research needs are identified by policy makers or service providers, and when research findings can be delivered. To think about the research needs of the future, it was necessary to first imagine what life might be like in 2030. What might Australia be like then, and the world? And what might the lives of Aboriginal and Torres Strait Islander people be? Workshops were held around the country to consider issues and trends visible in the current landscape, and how these might play out to influence life in 2030. A range of possible scenarios emerged, clustering around two divergent futures: an inclusive, vibrant Australia in which Aboriginal and Torres Strait Islander cultures are valued and embraced as central to the Australian identity; or an Australia in which economic and/or spiritual poverty drive a rejection of diversity and increase the divide between rich and poor. Participants then grappled with the question: If this (or that) scenario occurs, then what will be needed from research? By thinking about the range of possible scenarios for life in 2030, what capabilities are required to deliver the research that will be needed to address emerging issues and create a healthy future? The inspirational and empowering answer—perhaps not surprisingly—was not simply a list of research topics. Instead, participants articulated a strong and widely shared desire for a profoundly different system of research. A vision emerged of a research system in which research and practice are closely interwoven and which would enable greater integration of health services, policy and research. Such a system would be responsive to changing research demands, but also to changing social, economic, technological and knowledge landscapes. Specific research capabilities were also identified. An urgent necessity to actively address the social determinants of health was articulated in every workshop, along with a growing sense that the health and health research sectors may need to play a facilitating role, inviting other sectors—such as education, justice, local government—to collaborate and maximise the impact of their collective efforts to bring about change. A need for more evidence and evaluation around early childhood development programs (social as well as physical development) was seen as a priority for the immediate future. The Aboriginal and Torres Strait Islander health and health research sectors have played a pioneering role in the reform of research in Australia. The strength of vision articulated by participants in this project, and the desire to see that vision become a reality, suggests the sector will succeed in its drive toward a vision of a more effective research system

    Taxonomy of P2P Applications

    Get PDF
    Peer-to-peer (p2p) networks have gained immense popularity in recent years and the number of services they provide continuously rises. Where p2p-networks were formerly known as file-sharing networks, p2p is now also used for services like VoIP and IPTV. With so many different p2p applications and services the need for a taxonomy framework rises. This paper describes the available p2p applications grouped by the services they provide. A taxonomy framework is proposed to classify old and recent p2p applications based on their characteristics

    Organic Milk Quality in the Netherlands : Distinguishable from conventional milk?

    Get PDF
    Recent studies have indicated possible positive interactions between organic animal production and, particularly, and various vitamins. As possible distinguishing quality parameters for organic milk, the differences between organic and conventional milk in Netherlands for fatty acid composition and vitamins were investigated in milk samples form supermarkets at several points in time. We have also investigated possible differences in taste and two alternative analytical parameters (bio-photons and bio-crystallisations) because a single quality parameter, like poly-unsaturated fatty acids (PUFA), hardly reflects organic intentions to produce quality in a more holistic way being an inherent reflection of proper agricultural practices. These two alternative parameters try to relate to the hypothesis stating that the structure (the ‘order’) of food is just as important to human health as the material composition (Bloksma et al, 2008)

    Numerical thermo-elasto-plastic analysis of residual stresses on different scales during cooling of hot forming parts

    Get PDF
    In current research, more and more attention is paid to the understanding of residual stress states as well as the application of targeted residual stresses to extend e.g. life time or stiffness of a part. In course of that, the numerical simulation and analysis of the forming process of components, which goes along with the evolution of residual stresses, play an important role. In this contribution, we focus on the residual stresses arising from the austenite-to-martensite transformation at microscopic and mesoscopic level of a Cr-alloyed steel. A combination of a Multi-Phase-Field model and a two-scale Finite Element simulation is utilized for numerical analysis. A first microscopic simulation considers the lattice change, such that the results can be homogenized and applied on the mesoscale. Based on this result, a polycrystal consisting of a certain number of austenitic grains is built and the phase transformation from austenite to martensite is described with respect to the mesoscale. Afterwards, in a two-scale Finite Element simulation the plastic effects are considered and resulting residual stress states are computed

    The prevention of potato volunteers in organic farming systems by using pigs.

    Get PDF
    In organic agriculture potato volunteers, presenting an important primary inoculum source for late Blight (Phytophthora infestans), are controlled by mechanical meth-ods. These may be partly replaced by ‘foraging’ livestock animals, such as cattle, sheep, horses, ponies or pigs. Most animals eat only the remaining potatoes on the field surface; however, pigs also dig up potatoes. This paper reports on two experi-ments with pigs (sows or finishing pigs), which appear to be very effective in digging up potatoes that are left in the field after the potato harvest within a reasonable time period. However, the workload for the farmer, problems with animal health and meat quality and possible damage to the soil structure seriously limit the applicability of pigs for the control of potato volunteers. Aspects of animal health, animal nutrition and environmental aspects (nutrient excretion) are discussed

    On the capacity and normalisation of ISI channels

    Get PDF
    [Abstract]: We investigate the capacity of various ISI channels with additive white Gaussian noise. Previous papers showed a minimum Eb/N0 of −4.6 dB, 3 dB below the capacity of a flat channel, is obtained using the water-pouring capacity formulas for the 1 + D channel. However, these papers did not take into account that the channel power gain can be greater than unity when water-pouring is used. We present a generic power normalization method of the channel frequency response, namely peak bandwidth normalisation, to facilitate the fair capacity comparison of various ISI channels. Three types of ISI channel, i.e., adder channels, RC channels and magnetic recording channels, are examined. By using our channel power gain normalization, the capacity curves of these ISI channels are shown

    The asymptotic behaviour of the solutions of certain difference-differential equations

    Get PDF
    AbstractThe paper settles the asymptotic behaviour of the solutions of the difference-differential equation (1.1) in a case that was left open in N. G. de Bruijn [1]. Theorem 3.1 states that in this case all solutions have limits for x → ∞. A result about the speed of convergence is given by theorem 4.1
