Background: Urban and rural communities differ in the incidence of several diseases including coronary heart disease and some cancers. Lower hip fracture rates among rural than urban populations have been reported but few studies have compared rural and urban fractures at sites other than the hip.
Objective: To compare total and site specific fracture rates among adult residents of rural and urban communities within the same population.
Design and setting: This is a population based study on osteoporosis in Australia. All fractures occurring in adult residents over a two year period were ascertained using radiological reports. The rural and urban areas are in close proximity, with the same medical, hospital, and radiological facilities permitting uniform fracture ascertainment.
Main outcome measures: All fracture rates were age adjusted and sex adjusted to the Australian population according to the 1996 census of the Australian Bureau of Statistics and described as the rate per 10 000 person years. The p values refer to the adjusted rate difference.
Results: The hip fracture rate (incidence per 10 000 person years) was 32% lower (39 v 57, p<0.001), and the total fracture rate 15% lower (160 v 188, p=0.004) among rural than urban residents, respectively. The lower fracture rates in the rural population were also apparent for pelvic fractures.
Conclusion: In the older rural population, lower fracture rates at sites typically associated with osteoporosis suggest environmental factors may have a different impact on bone health in this community. If the national rate of hip fracture could be reduced to that of the rural population, the projected increase in hip fracture number attributable to aging of the population could be prevented.

Computerised ID scanning technologies have permeated many urban night-time economies in Australia, the United States, Canada and the United Kingdom. This paper documents how one media organisation’s overt and tacit approval of ID scanners helped to normalise this form of surveillance as a precondition of entry into most licensed venues in the Australian city of Geelong. After outlining how processes of governance “from above” and “from below” interweave to generate distinct political and media demands for strategies to prevent localised crime problems, a chronological reconstruction of media reports over a three-and-a half year period demonstrates how ID scanning became the centrepiece of a holistic reform strategy to combat alcohol-related violence in this nightclub precinct. Several discursive techniques helped to normalise this “technological fix”, while suppressing critical discussion of viable concerns over information privacy, data security and system networking. These
included pairing reports of an initial “signal crime” with examples of “virtual victimhood” to stress the urgency of a radical surveillance-based response, which was supported by anecdotal statements from key “primary definers” highlighting the success of this initiative in targeting a wider population of antisocial “others”. The implications of these reporting practices are discussed in light of the media’s central role in reforming the Geelong night-time economy and broader trends in using novel surveillance technologies to combat urban crime problems at the expense of alternative measures that protect individual liberty.

The National Climate change Adaptation Research Plan: Indigenous Communities (2011) highlighted that research on Indigenous communities and climate change, including the variables of impacts, vulnerability and adaptive capacity and adaptation has been limited. While most research has focused on identifying the biophysical impacts of climate change, a minority of studies have considered the Indigenous knowledge and peoples whom continue to reside in Australia and care for; ‘country’;. The report concluded that “there is a need for research that expands knowledge about these and other dimensions of Indigenous adaptation to climate change.“ This paper reviews work in progress on a NCCARF funded research project that is seeking to investigate select coastal urban and per-urban Indigenous community vulnerability to, and capacity for climate change adaptation. Working collaboratively with Indigenous communities resident in Adelaide, Heywood/Portland, Mornington Peninsula, Stradbroke Island and Brisbane, it seeks to explore and articulate strategies that enhance Indigenous capacity to climate change including possible protocols, frameworks, processes and procedures that may lead directly to a more informed appreciation of what is transpiring around Australia’s coastal per-urban regions for their Indigenous communities who still hold strong bonds and responsibilities to their ‘country’.

Landscape perception from the cultural ecology perspective can help us understand what urban natural landscapes mean to people from different cultures, and how they make sense of place through landscape experience. While there are key anthropological studies on culture and environment, there is not extensive literature about how post-war and more recent immigrants appropriate, use and perceive natural environments? And do migrants' culture and experience of nature in their previous places of dwelling affect their perception and experience in a new landscape? In a global world conditioned by mobility, it may be important to understand the factors that affect immigrants' perception of place and the phenomenon of the sense of belonging as mediated by their approach to nature. This paper explores the experience of migration in relation to urban natural landscapes, and studies the role of natural environments in their place making and identity.

To achieve valid conclusions, studies exploring associations of the built environment with residents' physical activity and health-related outcomes need to employ statistical approaches accounting for clustered data. This article discusses the following main statistical approaches: analysis of covariance, regression models with robust standard errors, generalized estimating equations, and multilevel generalized linear models. The choice of a statistical method depends on the characteristics of the study and research questions. While the first three approaches are employed to account for clustering in the data, multilevel models can also help unravel more substantive issues within a social ecological theoretical framework of health behavior.

Studies of gentrification in Australia have typically analysed the phenomenon through the lens of housing and residential change. This article explores how non-residential factors, including the concept of and the everyday practices associated with cosmopolitanism, offer an opportunity to analyse leisure specific to gentrification in Melbourne in the 1960s and 1970s. The article particularly explores leisure based on food and drink cultures located in restaurants, cafés and pubs. Adopting a discursive interdisciplinary approach to studies of the urban past, the article seeks to enhance our historical understanding of the interplay between gentrification and cosmopolitan leisure at a specific place and time in history, by exploring how people perceived themselves and their lifestyles in the midst of urban change.

It is generally accepted that good practice in policy making and urban change initiatives requires community engagement, where community-based approaches are emphasised as a means of socially inclusive visioning. Communities expect greater transparency, accountability and engagement. This expectation is not always met, with many studies focusing on the perceived tickbox effect - where engagement is a process that has to be undertaken rather than being welcomed and embraced as an integral part of planning for urban change. This paper explores multi-disciplinary concepts and looks at ways these can be linked to community engagement in planning, particularly in larger urban Councils. In this brief glimpse at the wide variety of disciplines that could be drawn on, the paper uses information systems, teaching models, organisational theory and public policy to highlight the potential for altering concepts of community engagement. It concludes that, from these particular examples: the use of double-loop learning could help to empower the community (from organisational theory), collaboration and participation necessitate the co-ordination and exchange of information and knowledge within and between organisations (information systems), the preconception that the authority holds all the knowledge ready to be handed out to the community (teaching models) needs to be challenged, and partnerships are important in empowering people (public policy).

Temporary urban spaces are gaining even more footing and acceptance on the political agenda as a result of their potential for creating eventful, cultural and creative urban environments. This political focus on temporary urban space is an indication of general urban regulations and development tendencies characterized by cultural planning, leisure, economy, collaborative planning and an increased focus on everyday life. Particularly economic parameters related to leisure such as creativity, culture, urban life and experiences are highly prioritized on the urban municipal agenda, with temporary uses as a concrete development tool. An interesting dichotomy has also arisen between the use of temporary space as a tool for social planning by urban designers as opposed to the use of temporary spaces by politicians as a vehicle for economic gain through leisure spaces. This paper focuses on the phenomenon of Temporary Use as a city-political focus area now and in the future as well as the use of the temporary as a planning tool. Several case studies are used to illustrate these topics.

Urban lakes are typically smaller, shallower, and more exposed to human activities than natural lakes. Although the effects of harmful algal blooms (HABs) associated with eutrophication in urban lakes has become a growing concern for water resources management and environmental protection, studies focussing on this topic in relation to urban lakes are rare and knowledge of the ecological dynamics and effective management strategies for controlling eutrophication in urban lakes is lacking. This study applied an integrated three-dimensional hydrodynamics-ecological model for a small shallow tropical urban lake in Singapore and evaluated various management scenarios to control eutrophication in the lake. It is found that in-lake treatment techniques including artificial destratification, sediment manipulation and algaecide addition are either ineffective or possess environmental concerns; while watershed management strategies including hydraulic flushing and inflow nutrients reduction are more effective and have posed less environmental concerns. In this study, inflow phosphorus reduction was found to be the best strategy after evaluating the advantages and drawbacks of the management strategies studied. Runoff from the watershed exerts significant influence on urban lakes and thus an integrated water resources management at the watershed level is critical for the control of eutrophication

This article examines whether subjective economic assessments have any impact on support for further market reforms among China's urban population, utilising a large survey of 10,716 people across 32 cities. The effect of subjective economic well-being on support for market reforms is an important issue for the Chinese government as it seeks to sell the benefits of increased globalisation and marketisation to its citizens. Our main finding is that people's assessment of the overall economic situation helps to explain support for market reform, although the relationship is weak, while people's assessment of their own economic circumstances does not influence support for reform. The findings are compared with those of similar studies for Central and Eastern Europe. © 2005 Centre for Research into Post-Communist Economies.

We examine the relationship between atmospheric and water pollution, traffic congestion, access to parkland and personal well-being using a survey administered across six Chinese cities in 2007. In contrast to existing studies of well-being determinants by economists which typically employ single-item indicators, we use the Personal Well-being Index (PWI). We also employ the Job Satisfaction Survey (JSS) to measure job satisfaction, which is one of the variables for which we control when examining the relationship between environmental surroundings and personal well-being. Previous research by psychologists has shown the PWI and JSS to have good psychometric properties in western and Chinese samples. A robust finding is that in cities with higher levels of atmospheric pollution and traffic congestion, respondents report lower levels of personal well-being ceteris paribus. Specifically, we find that a one standard deviation increase in suspended particles or sulphur dioxide emissions is roughly equivalent to a 12-13% reduction in average monthly income in the six cities. © 2010 Springer Science+Business Media, LLC.

While physical activity (PA) provides many physical, social, and mental health benefits for older adults, they are the least physically active age group. Ecological models highlight the importance of the physical environment in promoting PA. However, results of previous quantitative research revealed inconsistencies in environmental correlates of older adults' PA that may be explained by methodological issues. Qualitative studies can inform and complement quantitative research on environment-PA relationships by providing insight into how and why the environment influences participants' PA behaviors. The current study aimed to provide a systematic review of qualitative studies exploring the potential impact of the physical environment on older adults' PA behaviors.

BackgroundWe have previously demonstrated that between the years 1980 and 2000, the mean body mass index (BMI) of the urban Australian population increased, with greater increases observed with increasing BMI. The current study aimed to quantify trends over time in BMI according to education between 1980 and 2007.MethodsWe compared data from the 1980, 1983 and 1989 National Heart Foundation Risk Factor Prevalence Studies, 1995 National Nutrition Survey, 2000 Australian Diabetes, Obesity and Lifestyle Study and the 2007 National Health Survey. For survey comparability, analyses were restricted to urban Australian residents aged 25-64 years. BMI was calculated from measured height and weight. The education variable was dichotomised at completion of secondary school. Four age-standardised BMI indicators were compared over time by sex and education: mean BMI, mean BMI of the top five percent of the BMI distribution, prevalence of obesity (BMI⩾30 kg/m(2)), prevalence of class II(+) obesity (BMI⩾35 kg/m(2)).ResultsBetween 1980 and 2007, the mean BMI among men increased by 2.5 kg/m(2) and 1.7 kg/m(2) for those with low and high education levels, respectively, corresponding to increases in obesity prevalence of 20(from 12% to 32%) and 11(10% to 21%) %-points. Among women mean BMI increased by 2.9 kg/m(2) and 2.4 kg/m(2) for those with low and high education levels respectively, corresponding to increases in obesity prevalence of 16(12% to 28%) and 12(7% to 19%) %-points. The prevalence of class II(+) obesity among men increased by 9(1% to 10%) and 4(1% to 5%) %-points for those with low and high education levels, and among women increased by 8(4% to 12%) and 4(2% to 6%) %-points. Absolute and relative differences between education groups generally increased over time.ConclusionsEducational differences in BMI have persisted among urban Australian adults since 1980 without improvement. Obesity prevention policies will need to be effective in those with greatest socio-economic disadvantage if we are to equitably and effectively address the population burden of obesity and its corollaries.International Journal of Obesity accepted article preview online, 16 March 2015. doi:10.1038/ijo.2015.27.

Educational campaigning has received little attention in the literature. This study investigates long-term and organised urban campaigns that are collectively lobbying the Victorian State Government in Australia, for a new public high school to be constructed in their suburb. A public high school is also known as a state school, government school, or an ordinary comprehensive school. It receives the majority of its funding from the State and Federal Australian Government, and is generally regarded as ‘free’ education, in comparison to a private school. Whilst the campaigners frame their requests as for a ‘public school’, their primary appeal is for a local school in their community. This study questions how collective campaigning for a locale-specific public school is influenced by geography, class and identity. In order to explore these campaigns, I draw on formative studies of middle-class school choice from an Australian and United Kingdom perspective (Campbell, Proctor, & Sherington, 2009; Reay, Crozier, & James, 2011). To think about the role of geography and space in these processes of choice, I look to apply Harvey’s (1973) theory of absolute, relational and relative space. I use Bourdieu (1999b) as a sociological lens that is attentive to “site effects” and it is through this lens that I think about class as a “collection of properties” (Bourdieu, 1984, p. 106), actualised via mechanisms of identity and representation (Hall, 1996; Rose, 1996a, 1996b). This study redresses three distinct gaps in the literature: first, I focus attention on a contemporary middle-class choice strategy—that is, collective campaigning for a public school. Research within this field is significantly under-developed, despite this choice strategy being on the rise. Second, previous research argues that certain middle-class choosers regard the local public school as “inferior” in some way (Reay, et al., 2011, p. 111), merely acting as a “safety net” (Campbell, et al., 2009, p. 5) and connected to the working-class chooser (Reay & Ball, 1997). The campaigners are characteristic of the middle-class school chooser, but they are purposefully and strategically seeking out the local public school. Therefore, this study looks to build on work by Reay, et al. (2011) in thinking about “against-the-grain school choice”, specifically within the Australian context. Third, this study uses visual and graphic methods in order to examine the influence of geography in the education market (Taylor, 2001). I see the visualisation of space and schooling that I offer in this dissertation as a key theoretical contribution of this study. I draw on a number of data sets, both qualitative and quantitative, to explore the research questions. I interviewed campaigners and attended campaign meetings as participant observer; I collected statistical data from fifteen different suburbs and schools, and conducted comparative analyses of each. These analyses are displayed by using visual graphs. This study uses maps created by a professional graphic designer and photographs by a professional photographer; I draw on publications by the campaigners themselves, such as surveys, reports and social media; but also, interviews with campaigners that are published in local or state newspapers. The multiple data sets enable an immersive and rich graphic ethnography. This study contributes by building on understandings of how particular sociological cohorts of choosers are engaging with, and choosing, the urban public school in Australia. It is relevant for policy making, in that it comes at a time of increasing privatisation and a move toward independent public schools. This study identifies cohorts of choosers that are employing individual and collective political strategies to obtain a specific school, and it identifies this cohort via explicit class-based characteristics and their school choice behaviours. I look to use fresh theoretical and methodological approaches that emphasise space and geography, theorising geo-identity and the pseudo-private school

Bicycle advisory treatments are used to advise road users of the potential presence of cyclists and of the location where cyclists may be expected to ride on a road. They include pavement markings, warning signs, guide signs, and as such have no regulatory function. The most common type of bicycle advisory pavement markings is the shared lane marking. Other forms of bicycle advisory pavement marking have also been trialled and used in several local jurisdictions. The bicycle awareness zone is an example of such facility which has been trialled and used in southeast Queensland, Australia since the late 1990s. A bicycle awareness zone is similar to shared lane marking in principle but differs in the type of logo and, in some cases, location of its placement on the road. This study assesses the operational and safety issues at three bicycle awareness zone sites by analysing video-assisted observation data collected in 2011 by Queensland Department of Transport and Main Roads, Australia. Of the several applications of bicycle awareness zones, this study only covers a particular application where the centre of the bicycle symbol is placed exactly over the parking edge line. Unlike previous studies, which mostly covered before-and-after evaluations of bicycle advisory pavement markings, the focus of this study is to assess whether the placement of bicycle awareness zone symbols has been successful. The aggregated results from video-assisted observational data show that the cyclists did not always track themselves over the centre of the symbols. Rather, both the cyclists' lateral tracking positions and road user interactions varied with the widths of kerbside parallel parking space. Since the bicycle awareness zone symbols are not positioned on the cyclists' desired line of ride on some roads, their operational effectiveness and safety value are questioned.
