Cardiac ARIA Index: Measuring Accessibility to Cardiovascular Services in Rural and Remote Australia via Applied Geographic Spatial Technology

Cardiovascular disease (CVD) continues to impose a heavy burden in terms of cost, disability and death in Australia. Evidence suggests that increasing remoteness, where cardiac services are scarce, is linked to an increased risk of dying from CVD. Fatal CVD events are reported to be between 20% and 50% higher in rural areas compared to major cities. The Cardiac ARIA project, with its extensive use of geographic Information Systems (GIS), ranks each of Australia’s 20,387 urban, rural and remote population centres by accessibility to essential services or resources for the management of a cardiac event. This unique, innovative and highly collaborative project delivers a powerful tool to highlight and combat the burden imposed by cardiovascular disease (CVD) in Australia. Cardiac ARIA is innovative. It is a model that could be applied internationally and to other acute and chronic conditions such as mental health, midwifery, cancer, respiratory, diabetes and burns services. Cardiac ARIA was designed to: 1. Determine by expert panel, what were the minimal services and resources required for the management of a cardiac event in any urban, rural or remote population locations in Australia using a single patient pathway to access care. 2. Derive a classification using GIS accessibility modelling for each of Australia’s 20,387 urban, rural and remote population locations. 3. Compare the Cardiac ARIA categories and population locations with census derived population characteristics. Key findings are as follows: • In the event of a cardiac emergency, the majority of Australians had very good access to cardiac services. Approximately 71% or 13.9 million people lived within one hour of a category one hospital. • 68% of older Australians lived within one hour of a category one hospital (Principal Referral Hospital with access to Cardiac Catheterisation). • Only 40% of indigenous people lived within one hour of the category one hospital. • 16% (74000) of indigenous people lived more than one hour from a hospital. • 3% (91,000) of people 65 years of age or older lived more than one hour from any hospital or clinic. • Approximately 96%, or 19 million, of people lived within one hour of the four key services to support cardiac rehabilitation and secondary prevention. • 75% of indigenous people lived within one hour of the four cardiac rehabilitation services to support cardiac rehabilitation and secondary prevention. Fourteen percent (64,000 persons) indigenous people had poor access to the four key services to support cardiac rehabilitation and secondary prevention. • 12% (56,000) of indigenous people were more than one hour from a hospital and only had access one the four key services (usually a medical service) to support cardiac rehabilitation and secondary prevention.

CARDIAC-ARIA: Measuring the Accessibility to Cardiovascular Services in Rural and Remote Australia Via Applied Geographical Spatial Technology (GIS)

Background/aims: Cardiovascular disease (CVD) continues to impose a heavy burden in terms of cost, disability and death in Australia. Recent evidence suggests that increasing remoteness, where cardiac services are scarce, is linked to an increased risk of dying from CVD. Fatal CVD events are reported to be between 20% and 50% higher in rural areas compared to major cities. Method: This project, with its extensive use of Geographic Information Systems (GIS) technology, will rank 11,338 rural and remote population centres to identify geographical ‘hotspots’ where there is likely to be a mismatch between the demand for and actual provision of cardiovascular services. It will, therefore, guide more equitable provision of services to rural and remote communities. Outcomes: The CARDIAC-ARIA project is designed to; map the type and location of cardiovascular services currently available in Australia, relative to the distribution of individuals who currently have symptomatic CVD; determine, by expert panel, what are the minimal requirements for comprehensive cardiovascular health support in metropolitan and rural communities and derive a rating classification based on the Accessibility and Remoteness Index of Australia (ARIA) for each of Australia's 11,338 rural and remote population centres. Conclusion: This unique, innovative and highly collaborative project has the potential to deliver a powerful tool to highlight and combat the burden imposed by cardiovascular disease (CVD) in Australia.

H. pylori-infection and antibody immune response in a rural Tanzanian population

Abstract Background: Helicobacter pylori (H. pylori) infection is ubiquitous in sub-Saharan Africa, but paradoxically gastric cancer is rare. Methods: Sera collected during a household-based survey in rural Tanzania in 1985 were tested for anti-H. pylori IgG and IgG subclass antibodies by enzyme immunoassay. Odds ratios (OR) and confidence intervals (CI) of association of seropositivity with demographic variables were computed by logistic regression models. Results: Of 788 participants, 513 were aged ≤17 years. H. pylori seropositivity increased from 76% at 0–4 years to 99% by ≥18 years of age. Seropositivity was associated with age (OR 11.5, 95% CI 4.2–31.4 for 10–17 vs. 0–4 years), higher birth-order (11.1; 3.6–34.1 for ≥3rd vs. 1st born), and having a seropositive next-older sibling (2.7; 0.9–8.3). Median values of IgG subclass were 7.2 for IgG1 and 2.0 for IgG2. The median IgG1/IgG2 ratio was 3.1 (IQR: 1.7–5.6), consistent with a Th2- dominant immune profile. Th2-dominant response was more frequent in children than adults (OR 2.4, 95% CI 1.3–4.4). Conclusion: H. pylori seropositivity was highly prevalent in Tanzania and the immunological response was Th2-dominant. Th2-dominant immune response, possibly caused by concurrent bacterial or parasitic infections, could explain, in part, the lower risk of H. pylori-associated gastric cancer in Africa.

Analysis of rural MUSA-MIMO-OFDM uplink channel capacity

Multi-user single antenna multiple-input multiple-output orthogonal frequency division multiplexing (MUSA-MIMO-OFDM) is a promising technology to improve the spectrum efficiency of fixed wireless broadband access systems in rural areas. This letter investigates the capacity of MUSA-MIMO-OFDM uplink channel by theoretical, simulation, and empirical approaches considering up to six users. We propose an empirical capacity formula suitable for rural areas. Characteristics of channel capacity temporal variations and their relationship with the wind speed, observed in a rural area, are also presented in this letter.

Prediction and measurement of multiuser MIMO-OFDM channel in rural Australia

Commonwealth Scientific and Industrial Research Organization (CSIRO) has recently conducted a technology demonstration of a novel fixed wireless broadband access system in rural Australia. The system is based on multi user multiple-input multiple-output orthogonal frequency division multiplexing (MU-MIMO-OFDM). It demonstrated an uplink of six simultaneous users with distances ranging from 10 m to 8.5 km from a central tower, achieving 20 bits s/Hz spectrum efficiency. This paper reports on the analysis of channel capacity and bit error probability simulation based on the measured MUMIMO-OFDM channels obtained during the demonstration, and their comparison with the results based on channels simulated by a novel geometric optics based channel model suitable for MU-MIMO OFDM in rural areas. Despite its simplicity, the model was found to predict channel capacity and bit error rate probability accurately for a typical MU-MIMO-OFDM deployment scenario.

Thinking Critically About Rural Gender Relations: Toward a Rural Masculinity/Male Peer Support Model of Separation/Divorce Sexual Assault

After decades of neglect, a growing number of scholars have turned their attention to issues of crime and criminal justice in the rural context. Despite this improvement, rural crime research is underdeveloped theoretically, and is little informed by critical criminological perspectives. In this article, we introduce the broad tenets of a multi-level theory that links social and economic change to the reinforcement of rural patriarchy and male peer support, and in turn, how they are linked to separation/divorce sexual assault. We begin by addressing a series of misconceptions about what is rural, rural homogeneity and commonly held presumptions about the relationship of rurality, collective efficacy (and related concepts) and crime. We conclude by recommending more focused research, both qualitative and quantitative, to uncover specific link between the rural transformation and violence against women.

Dangerous Exits: The Abuse of Women in Rural America

Decade after decade, violence against women has gained more attention from scholars, policy makers, and the general public. Social scientists in particular have contributed significant empirical and theoretical understandings to this issue. Strikingly, scant attention has focused on the victimization of women who want to leave their hostile partners. This groundbreaking work challenges the perception that rural communities are safe havens from the brutality of urban living. Identifying hidden crimes of economic blackmail and psychological mistreatment, and the complex relationship between patriarchy and abuse, Walter S. DeKeseredy and Martin D. Schwartz propose concrete and effective solutions, giving voice to women who have often suffered in silence.

Policing the Rural Crisis

Based on empirical research in a number of rural communities in north-western NSW, this article explores the dynamics of rural crisis as it is manifested in and through popular attitudes and campaigns around law and order. There is no denying that crime rates in many rural communities are high, often very high by national standards, or that local crime disproportionately involves Indigenous offenders (and Indigenous victims). However, the views expressed in interviews with established White residents, in local media and in organised campaigns around law and order are suggestive of a much deeper sense of threat and crisis. This, it is argued, can be explained in relation not simply to crime rates but the way in which crime is experienced at the local level and the manner in which it is connected to other unwanted change that is seen to threaten the integrity of these communities. In order to understand these anxieties it is necessary to explore historical patterns of settlement, the economic structure and the culture of rural communities. Indigenous Australians have, at best, occupied an ambiguous and fragile position in relation to membership of these communities, a form of ‘passive’ belonging, ‘conditional’ on deference to dominant White norms governing civic and domestic life. Local Indigenous crime can be a source of deep anxiety not only because it causes harm to person and property but because it is interpreted by many Whites as a repudiation of the local social order, a signifier of larger threats to the community and on occasions as a harbinger of social breakdown. The article explores some of the key themes emerging from interview material that characterise this sense of crisis and relates them to the larger pattern of change affecting many communities: economic decline, changing government policies and priorities, the growing relative economic and political power of Indigenous people, debates about native title and so on.

Crime in Rural Australia

Contemporary rural crime is more varied and sophisticated than it once was. The new forms range from agricultural crimes, such as the theft of water designated for agricultural production, to environmental crimes such as the illegal dumping of waste. They take place side by side with “traditional” rural crimes such as cattle duffing while “urban” crimes such as drug and alcohol abuse and violent assaults are also prevalent, and on the rise. Crime in Rural Australia covers them all. It brings together leading academics who examine the major dimensions of crime and justice in rural and regional Australia including: •the extent of rural crime •farm crime •violence •juvenile crime •policing •Indigenous crime and justice •crime prevention •drugs •fear of crime, and •sentencing and punishment. It includes vignettes on rural policing and the stock squad from the perspectives of the NSW police. An ideal text for rural crime and criminology courses, Crime in Rural Australia will also be of interest to criminal justice practitioners, policy-makers, and criminology scholars. Three of the editors, Dr Elaine Barclay, Dr John Scott and Associate Professor Russell Hogg, are associated with the Centre for Rural Crime at the University of New England. Professor Joseph F. Donnermeyer is the International Research Co-ordinator for the Rural Crime Centre and is a leading US scholar on rural crime at Ohio State University.
