Remote Areas Statistical Geography in Australia: Notes on the Accessibility/Remoteness Index for Australia (ARIA + version)

© Commonwealth of Australia 2003There have been increasing concerns over a number of years about the difficulties faced by Australians living in rural and remote areas of Australia in accessing services that most Australians take for granted. A parallel concern has been the extent to which the health of people living in these areas is poorer than that of those living in areas with greater accessibility to health, welfare and other services. Government in particular has been interested in finding out more about the circumstances and needs of these populations, and in targeting assistance accordingly. This led the (then) Department of Health and Aged Care (DHAC) to sponsor a project to obtain a standard classification and index of remoteness which would allow the comparison of information about populations based on their access, by road, to service centres (towns) of various sizes. Note that although by specifying towns of various sizes the index implicitly takes account of the education, health, welfare, etc. services likely to be located in towns of those sizes, there is no explicit use in the development of the index of what services should exist. That is, distance is the sole measure of access. The outcome of that project was the Accessibility/ Remoteness Index of Australia (ARIA) (DHAC 1999, superseded by DHAC 2001), based on a methodology developed by the National Centre for Social Applications in GIS (GISCA). More recently, the Australian Bureau of Statistics (ABS) addressed the concept of remoteness, with a view to including it in its classification of areas. The ABS work, also undertaken with GISCA, used ARIA as the underlying methodology for the determination of remoteness. The new classification, described by the ABS as a 'Remoteness Structure', is referred to as ARIA+ (ie., ARIA plus, ABS 2001a), and is an update and refinement of the original ARIA. This report includes a comparison of ARIA with ARIA+. It also examines the characteristics of the population under ARIA+, such as the distribution, age, sex, and includes comparisons by Indigenous status

Is it working ... together? Linking research, policy and practice in relation to children and health inequalities in South Australia

Despite an increasing interest in the extent of child health inequalities in Australia and effective strategies to address them, there remains a significant gap between existing research evidence and its incorporation into planning, policy and practice in Australia. Researchers, policy-makers and practitioners face difficulties in bringing research into practice effectively, and local communities are often neglected in the processes. This paper presents a brief summary of data on child health inequalities in South Australia over the last decade. It then reviews the extent to which research findings have been incorporated into human services' policy and practice. Particular barriers for researchers, policy-makers, planners, practitioners and communities are discussed, drawing on local and overseas experience, and possible strategies for addressing some of the barriers are outlined

The impact of socioeconomic status and geographic location on Indigenous mortality in Australia, 1997-99

© Commonwealth of AustraliaAustralia's Aboriginal peoples and Torres Strait Islanders have the poorest health of any group in Australia. This has been the case for many years. Given that Australia has not made the advances in Indigenous health achieved in comparable countries (such as Canada, the United States and New Zealand), it is likely to be the case for some time. This report presents data describing one outcome of that poor health, namely premature deaths of Indigenous people. It examines the higher death rates experienced by Indigenous people in the context of socioeconomic disadvantage and geographic location (in particular, remoteness). The measures of disadvantage and location are, themselves, a reflection of the continuing historical and cultural environment in which Australia?s Indigenous peoples have lived since colonisation. As such they cannot fully explain why Indigenous death rates are as high as they are; nor can they explain why death rates for Indigenous people are so much higher than for the most disadvantaged non-Indigenous populations. To do that requires an understanding of the historical and cultural environment, a discussion which is beyond the scope of this report, but which has been addressed by others (HREOC 1997; PHAA Inc. 1997; Bartlett 1999). Data analysis can, however, inform our understanding of the extent and nature of differences in variations in Indigenous and non-Indigenous mortality

The Status of Utah\u27s Agriculture and its Contribution to the State Economy

Growth in agricultural productivity and the migration of labor from agriculture to other employment has been a source of growth for the whole economy. From the times of pioneer settlement in Utah, more than 130 years ago, agricultural production has declined as a proportion of total economic activity. Employment, personal income, gross sales, and other measures can be shown to have declined as a proportion of the totals of these measures for the state. Yet, it is this very decline in dependence on workers producing food that has helped the economy to grow in size and variety both in Utah and throughout the nation

Energy Siting in Utah: A Programming Model

Using a conceptual model of a multiple-product firm, the necessary conditions for an optimal input and output allocation were determined for a region constrained by resource availabilities and/or policy constraints. A linear programming model was developed to deteremine the optimal allocation of water between agricultural and coal-fired electrical generating entities as well as the trade offs which could occur if electrical generation were increased. Other areas of potential trade offs such as coal source restrictions and air quality regualtions were also examined. Coal mining and transportation costs were included as were SO2, Nox, and particulate emission rates on a coal and plant basis. Few trade offs between electrical power generation and irrigated agriculture were noted. However, substantial changes within the energy sector were discovered as coal capacities and air quality energy sector were discovered as coal capacities and air quality standards were changed. Net revenues declined sharply as air costs after and/or pollution and coal capacity restrictions were imposed and/or increased. It was determined that substantial changes in regional economic activity occurred as a result of these restrictions on development

Analysis of Per Capita Contributions from a Spatial Model Provides Strategies for Controlling Spread of Invasive Carp

Metapopulation models may be applied to inform natural resource management to guide actions targeted at location-specific subpopulations. Model insights frequently help to understand which subpopulations to target and highlight the importance of connections among subpopulations. For example, managers often treat aquatic invasive species populations as discrete populations due to hydrological (e.g., lakes, pools formed by dams) or jurisdictional boundaries (e.g., river segments by country or jurisdictional units such as states or provinces). However, aquatic invasive species often have high rates of dispersion and migration among heterogenous locations, which complicates traditional metapopulation models and may not conform to management boundaries. Controlling invasive species requires consideration of spatial dynamics because local management activities (e.g., harvest, movement deterrents) may have important impacts on connected subpopulations. We expand upon previous work to create a spatial linear matrix model for an aquatic invasive species, Bighead Carp, in the Illinois River, USA, to examine the per capita contributions of specific subpopulations and impacts of different management scenarios on these subpopulations. Managers currently seek to prevent Bighead Carp from invading the Great Lakes via a connection between the Illinois Waterway and Lake Michigan by allocating management actions across a series of river pools. We applied the model to highlight how spatial variation in movement rates and recruitment can affect decisions about where management activities might occur. We found that where the model suggested management actions should occur depend crucially on the specific management goal (i.e., limiting the growth rate of the metapopulation vs. limiting the growth rate of the invasion front) and the per capita recruitment rate in downstream pools. Our findings illustrate the importance of linking metapopulation dynamics to management goals for invasive species control

Variability in the use of mobile ICTs by homeworkers and its consequences for boundary management and social isolation

We examine how the use of mobile information and communication technologies (ICTs) among self-employed homeworkers affects their experience of work, focusing particularly on where work is carried out, how the work/non-work boundary is managed, and people's experiences of social and professional isolation. Positively, their use enhanced people's sense of spatio-temporal freedom by allowing them to leave the home without compromising their work availability. This also helped reduce people's feelings of social isolation. More negatively, their use enhanced people's sense of 'perpetual contact', creating a sense that work was difficult to escape from. However, the extent to which mobile ICTs were used, and the extent to which their impact on people's experiences of work were understood, were found to vary significantly, highlighting the agency that users have with regard to technology use. The findings are framed by combining Nippert-Eng's boundary work theory, with an 'emergent process' perspective on socio-technical relations

Missing domesticated plant forms: can artificial selection fill the gap?

In the course of their evolution, the angiosperms have radiated into most known plant forms and life histories. Their adaptation to a recently created habitat, the crop field, produced a novel form: the plant that allocates an unprecedented 30–60% of its net productivity to sexual structures. Long-lived trees, shrubs and vines of this form evolved, as did annual herbs. Perennial herb forms with increased allocation to asexual reproduction evolved, but there are no examples of perennial herbs with high sexual effort. We suggest that sowing seed into annually tilled fields favored shorter-lived herbs because of trade-offs between first-year seed production and relative growth rate and/or persistence. By propagating cuttings, people quickly domesticated tuber crops and large woody plants. Perennial herbs were too small to be efficiently propagated by cuttings, and the association between longevity, allogamy and genetic load made rapid domestication by sexual cycles unlikely. Perennial grain crops do not exist because they could not have evolved under the original set of conditions; however, they can be deliberately developed today through artificial phenotypic and genotypic selection

Influenza Virus in Human Exhaled Breath: An Observational Study

Background: Recent studies suggest that humans exhale fine particles during tidal breathing but little is known of their composition, particularly during infection. Methodology/Principal Findings: We conducted a study of influenza infected patients to characterize influenza virus and particle concentrations in their exhaled breath. Patients presenting with influenza-like-illness, confirmed influenza A or B virus by rapid test, and onset within 3 days were recruited at three clinics in Hong Kong, China. We collected exhaled breath from each subject onto Teflon filters and measured exhaled particle concentrations using an optical particle counter. Filters were analyzed for influenza A and B viruses by quantitative polymerase chain reaction (qPCR). Twelve out of thirteen rapid test positive patients provided exhaled breath filter samples (7 subjects infected with influenza B virus and 5 subjects infected with influenza A virus). We detected influenza virus RNA in the exhaled breath of 4 (33%) subjects-three (60%) of the five patients infected with influenza A virus and one (14%) of the seven infected with influenza B virus. Exhaled influenza virus RNA generation rates ranged from <3.2 to 20 influenza virus RNA particles per minute. Over 87% of particles exhaled were under 1 μm in diameter. Conclusions: These findings regarding influenza virus RNA suggest that influenza virus may be contained in fine particles generated during tidal breathing, and add to the body of literature suggesting that fine particle aerosols may play a role in influenza transmission. © 2008 Fabian et al.published_or_final_versio
