When more is less : urban remnants support high bird abundance but diversity varies

Urban remnant vegetation, especially where it occurs in public parks, allows for relatively easy access for ongoing biodiversity monitoring. However, relatively little baseline information on bird species distribution and abundance across a range of identifiable urban remnants appears in the published literature. We surveyed the relative abundance and distribution of birds across urban and suburban remnant vegetation in Melbourne, Australia. One hundred and six species were recorded, of which 98 were indigenous. Red wattlebirds had the highest mean relative abundance with 2.94 birds/ha, followed by rainbow lorikeets (2.51), noisy miners (1.93), brown thornbills (1.75) and spotted doves (0.96). There was no obvious trend between overall relative abundance and the size of the remnant, in contrast to species richness which was positively correlated with remnant size. The data revealed that some species were either totally restricted to, or more abundant in, larger remnants and generally absent from smaller remnants. Some of the more common birds (crimson rosella, superb fairy-wren, spotted pardalote and black-faced cuckoo-shrike) recorded during this study were detected at similar densities to those found in comparable vegetation to the east of Melbourne within a largely forested landscape. Other species occurred at much lower densities (e.g., white-browed scrubwren, brown thornbill, eastern yellow robin and grey fantail) or had habitat requirements or ecological characteristics that could place them at risk of further decline or local extinction in the urban area. We identify a suite of bird species of potential conservation concern within Melbourne’s urban landscape. The establishment of repeatable, fixed-point, and long-term monitoring sites will allow for repeat surveying over time and provide an early warning of population declines, or conversely an indication of population increase for other species.

The association between urban or rural locality and hip fracture in community-based adults : a systematic review

Urban or rural locality has been suggested to influence musculoskeletal health, with lower bone mineral density (BMD) and greater prevalence of fracture identified in urban residents. A computer-aided search of Medline, EMBASE, CINAHL and PsychINFO, January 1966 to November 2007 was conducted to identify studies investigating the relationship between urban or rural locality and the occurrence of hip fracture. The methodological quality of studies was assessed, and a best-evidence synthesis was used to summarise the results. Fourteen cohort studies and one case-control study were identified for inclusion in this review, indicating a lack of literature in the field. Best-evidence analysis identified moderate evidence for residents of rural regions to have lower risk of hip fracture compared to urban residents. Examining principal mechanisms for the observed relationship between urban/rural locality and hip fracture, such as factors at the person or area level, may help to identify modifiable risk factors and inform appropriate prevention strategies.

Second city syndrome : media reportage of urban rankings

This paper investigates the popularly reported phenomenon of city rankings and, in particular, the category of the ‘second city’ that regularly features as part of this prolific evaluative discourse. Our paper proposes that the category ‘second city’ has a specific analytical value that has to date been underestimated in academic accounts (particularly in the confusing, interchangeable use of ‘second-tier’, ‘secondary’ and ‘second cities’ in the dominant urban studies literature). Instead, we are interested in how second city identifications permeate popular forms of urban comparison in some places.

The example of Melbourne (Australia) is used to investigate how second city identities are historically sustained through evaluative media representations. In particular we examine how, through their reportage of various world city rankings, metropolitan newspapers reveal and articulate a ‘second city consciousness’. How do media institutions, and more specifically, media reports, frame these urban rankings in such a way to confirm Melbourne’s similarity to other globalised places (i.e. proposing its status as a ‘world city’), yet also as a city also marked by a particular historical specificity? And how do they draw on already existing popular and political traditions of urban comparison? This article will identify and analyse the role of newspapers in perpetuating both formal and informal urban comparisons.

A study of building materials to create an identity of traditional Balinese architecture for urban housing

The use or local architecture characteristics is regulated by the spatial planning and building code of Indonesia. Balinese tmditional architecture has existed, coloured the traditional architecture of Indonesia and can be used as Bali's identity that is different from other regions in Indonesia.On the other hand, the cost of such building is high and most of people in urban areas are unable to afford to build in the traditional architecture style, especially in the residential housing sector .. Some of the major components that determine the price of housing units are the price of land, building materials, labour and technology. In developing countries, the first and second components that affect the unit price of the building are building materials representing about 70% and skilled labour respectively (Ural, 1980). Based on this, a good strategy to adopt in order to minimize the price is to manipulate these two components.Based on a literature review and observation, this study will explain which aspects of building material technology can reduce the building cost and how it can maintain the identity of local architecture.The results of the study indicate that the building material can be created to both reduce cost and adopt traditional architecture style as an identity. The materials have some shapes that can be joined easily to facilitate the skill of the worker and yet still be able to adopt the forms of traditional Balinese architecture.

Sense of place in urban natural landscapes

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.

Urban growth in arid environments : developing water sustainability indicators for Abu Dhabi (UAE)

The United Arab Emirates (UAE) face a serious water problem. It has a very dry climate, high evaporation rate, combined with large water consumption from fast growing population, economic activities and uncontrolled uses of water for irrigation. Currently, UAE has one of the largest water footprints in the world. Groundwater is overexploited. Waste water is increasingly being treated to supply non-drinking water, but it still cover a small proportion of the demand. Desalination of sea water is the main source of potable water in UAE, but the high economic cost of desalination, its intensive energy demand and the adverse effects of its effluents on the marine life are a major concern. Other factors contributing to the problem are the focus of water management policies on keep supplying the growing demand for water, the increase of the per capita water consumption, and the free water charge for most of population. This research goal is to develop a water sustainability set of indicators for the challenging context of UAE. This paper presents the first stage of the research. Based on a review of the literature, the proposed framework involves 19 indicators, divided into four categories: water availability; water quality; water use efficiency; and policy and governance. Using an integrated cause-effect approach (DSR - Driving force, State, Response), the indicators were related in terms of their interdependencies, with a holistic view of the city water cycle. A preliminary test of the indicators to Abu Dhabi as a case study allowed an evaluation of the main 'Driving force' on the system, such as the scarcity of water due to natural constraints of the region, and increasing water consumption patterns of modern society; an assessment of the current 'state', which is under serious water stress. Also it indicated some potential 'responses', such as implementing policies for increasing efficient use.

A new beginning? John Yandell's the social construction of reading in urban classrooms

John Yandell’s The Social Construction of Meaning: Reading Literature in Urban Classrooms provides a powerful counterpoint to current policy discourse in education. By focusing on the social interactions that occur in the classrooms of two English teachers, Yandell shows how their pupils are able to explore dimensions of language and experience that far exceed the outcomes prescribed by official curriculum documents. This is because their teachers conceive of reading as a social activity in which everyone can participate. Yandell thereby affirms the value of a literary education as an integral part of an educational project that is genuinely democratic and inclusive.

The moderating effects of demographic factors and hukou status on the job satisfaction-subjective well-being relationship in urban China

This study tests the moderating effect of job complexity and social status, proxied by a unique Chinese cultural variable (hukou status), on the relationship between job satisfaction and subjective well-being in urban China. Data on these and a range of demographic variables were collected from 1025 workers in Fujian Province in the People's Republic of China. Results confirm that hukou status does moderate the job satisfaction-subjective well-being relationship in this sample. Several further moderating relationships are also detected. The study adds the empirical literature on job satisfaction and subjective well-being in China and also furthers understanding of the complex relationship between these constructs. © 2011 Taylor & Francis.

Improving Indigenous Access to Early Childhood Services in Urban and Regional Areas

The literature on how to improve Indigenous access to early childhood services consists mainly of program descriptions and documented practice experience, with a limited number of formal program evaluations. Accessible early childhood services fulfil four overlapping dimensions. They are physically accessible; economically accessible (affordable); appropriate (comprehensive and non-discriminatory); and acceptable (respect and acknowledge culture).The literature suggests that there are five types of barriers to accessible early childhood services: individual; program; provider; social and neighbourhood; and cultural.It is not sufficient to just improve access—engagement strategies are also necessary to get families involved in the services that may benefit them.

Geo-identity, urban school choice and education campaigns for public schools

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

Geographical dimensions of imagined futures: post school participation in education and work in peri-urban and regional Australia

This paper discusses preliminary findings from a sub-set of empirical data collected for a recent NCVER study that explored the geographic dimensions of social exclusion in four locations in Victoria and South Australia with lower than average post school education participation. Set against the policy context of the Bradley Review (2008) and the drive to increase the post-school participation of young people from low socio-economic status neighbourhoods, this qualitative research study, responding to identified gaps in the literature, sought a nuanced understanding of how young people make decisions about their post-school pathways. Drawing on Appadurai’s (2004) concept ‘horizons of aspiration’ the paper explores the aspirations of two young people formed from, and within, their particular rural ‘neighborhoods’. The paper reveals how their post-school education and work choices, imagined futures and conceptions of a ‘good life’, have topographic and gendered influences that are important considerations for policy makers.

Who wants safer cities? Perceptions of public safety and attitudes to migrants among China's urban population

Most extant research in the economics of crime literature has focused on explaining variations in crime rates. Public action to prevent crime, however, is often dependent on the level of concern about public safety that is expressed in public perceptions surveys. The economics of crime literature has largely overlooked responses to such surveys as data sources and therefore it has not accounted for the role that public opinion might have in mobilizing public action against crime. We use a unique survey administered in 2003 in 32 Chinese cities to examine the determinants of perceptions of public safety among China's urban population. One of our major findings is that individuals who have a negative perception of rural-urban migrants living in their city have a poor perception of public safety. We also find that the unemployment rate, the masculinity ratio and expenditure on armed police in the city in which the individual resides, whether the individual lives in the coastal region as opposed to the central or western region and average changes in housing prices and average changes in rental prices in the city in which the individual lives are important predictors of perceptions of public safety. © 2007 Elsevier Inc.

Urbanization impacts on mammals across urban-forest edges and a predictive model of edge effects

With accelerating rates of urbanization worldwide, a better understanding of ecological processes at the wildland-urban interface is critical to conserve biodiversity. We explored the effects of high and low-density housing developments on forest-dwelling mammals. Based on habitat characteristics, we expected a gradual decline in species abundance across forest-urban edges and an increased decline rate in higher contrast edges. We surveyed arboreal mammals in sites of high and low housing density along 600 m transects that spanned urban areas and areas turn on adjacent native forest. We also surveyed forest controls to test whether edge effects extended beyond our edge transects. We fitted models describing richness, total abundance and individual species abundance. Low-density housing developments provided suitable habitat for most arboreal mammals. In contrast, high-density housing developments had lower species richness, total abundance and individual species abundance, but supported the highest abundances of an urban adapter (Trichosurus vulpecula). We did not find the predicted gradual decline in species abundance. Of four species analysed, three exhibited no response to the proximity of urban boundaries, but spilled over into adjacent urban habitat to differing extents. One species (Petaurus australis) had an extended negative response to urban boundaries, suggesting that urban development has impacts beyond 300 m into adjacent forest. Our empirical work demonstrates that high-density housing developments have negative effects on both community and species level responses, except for one urban adapter. We developed a new predictive model of edge effects based on our results and the literature. To predict animal responses across edges, our framework integrates for first time: (1) habitat quality/preference, (2) species response with the proximity to the adjacent habitat, and (3) spillover extent/sensitivity to adjacent habitat boundaries. This framework will allow scientists, managers and planners better understand and predict both species responses across edges and impacts of development in mosaic landscapes.

Do enhancements to the urban built environment improve physical activity levels among socially disadvantaged populations?

Background: There is growing recognition that the urban built environment influences physical activity at the population level, although the effects on disadvantaged groups are less well understood. Using the examples of open/green space and street connectivity, this paper explores whether enhancements to the built environment have potential for addressing physical activity-related health inequalities among Mori, Pacific and low income communities in New Zealand.

Method: A high-level review of the international literature relating open space and street connectivity to physical activity and/or related health outcomes at a population level was completed. Consideration was given to whether these features of the built environment have a disproportionate effect on disadvantaged populations.

Results: Findings from international studies suggest that open space and street connectivity have a beneficial effect on physical activity. Enhancing the built environment may be particularly advantageous for improving physical activity levels among disadvantaged populations.

Conclusion: It is likely that open space and street connectivity have a positive effect on physical activity behaviour; however due to the cross-sectional nature of existing research and the paucity of research among disadvantaged populations definitive conclusions about the effect in these populations cannot be made. Further research is required (e.g. natural experiments or quasi experimental research designs) to determine the effect of changing the environment on physical activity and obesity.

Improving the health of Australians by applying evidence from behavioural epidemiology to urban design projects

Rapid urban population growth in Australia requires an expansion of supporting hard and soft infrastructure. In the State of Victoria, directing this growth are a number of urban design and planning mechanisms that provide a ‘blueprint for development and investment’. Although topics revolving around physical health are present in these and other planning related documents, largely absent from this literature are ‘tools’ to assist decision makers in determining whether or not an urban setting supports physical health and provides opportunities for physical activity. Insufficient physical activity is a risk factor contributing to Australia’s growing and significant burden of chronic disease including cardiovascular disease, Type 2 diabetes and overweight/obesity. The potential of the built environment to influence population-level physical activity is well recognised. A key element in Victoria’s planning framework that can help address these health concerns is the provision and redevelopment of open space(s) in urban areas that provide opportunities for people of all ages and abilities to engage in physical activity. However, in the realisation of these settings, evidence informing the design of urban open space(s) that promote opportunities for physical activity is needed to produce evidence based decision making. Using the three geo-spatial visioning layers embedded in Victoria’s planning framework (i.e. Growth Area Framework Plans, Precinct Structure Plans and Planning Permits) as positioning instruments, this paper merges the fields of behavioural epidemiology and urban design to: i) provide a brief overview of current research relating to design of open space to optimise usage and physical activity, ii) consider what type of evidence relating to features of open space is needed to help inform decision makers, iii) consider the methods and procedures practitioners may use to incorporate evidence in to their planning, and iv) discuss the geo-spatial development level that the respective data can best assist decision making to achieve positive gains in physical health.
