Applying GIS in physical activity research: community walkability and walking behaviours.

Physical activity provides many health benefits, including reduced risk of cardiovascular disease, Type II diabetes and some cancers. Environmental exposure factors (e.g., the built environment) are now receiving ever-increasing attention. Large-scale interdisciplinary studies on the association between attributes of local community environments and residents’ physical activity are being conducted. We will focus on findings from Australia - the Physical Activity in Localities and Community Environments (PLACE) study. PLACE is examining factors that may influence the prevalence and the social and spatial distribution of walking for transport and walking for recreation. A stratified two-stage cluster sampling strategy was used to select 32 urban communities (154 census collection districts), classified as high and low ‘walkable’ using a GISbased walkability index (dwelling density, intersection density, net retail area and land use mix) and matched for socio-economic status. We report data on a sub-sample of 1,216 residents who provided information on the perceived attributes of their community environments (e.g., dwelling density, access to services, street connectivity) and weekly minutes of walking for transport and for recreation. Moderate to strong associations were found between GIS indicators of walkability and the corresponding self-report measures. The walkability index explained the same amount of neighborhood-level variance in walking for transport as did the complete set of self-report measures. No significant associations were found with walking for recreation. Relevant GIS-based indices of walkability, for purposes other than transport need to be   developed.

Modernist Success in a Postmodern Failure: Jackson Pollock and Abstract Expressionism, the Avant-Garde and the Ascension of Late Capitalism, Art after 1945

It is hard to imagine the magnitude of the events at the end of World War II. The thought produced in the face of a myriad of deaths is almost unfeasible sixty years after the fact, but the energy was integral to the changing social landscape. Because of the country's prominence in and fortitude after the war, the U.S. was left responsible for reshaping and rejuvenating the international landscape that was destroyed by the years of brutal fighting and vile contestation. The American establishment was granted a major opportunity to establish itself amongst the global leaders. Such a grand responsibility must account for the multiplicity of thought that arises in such a decisive moment. In order to align the Abstract Expressionist art movement with the intersection of the intense, multifaceted thought developed during the postwar period, the following will discuss the political, philosophical, economic, and art historical overlap that occurred in the mid to late 1940s in the hopes of illustrating the fertility yet lingering problems associated with the restructuring of the world with America at the helm. In this way, the duration of the Abstract Expressionist moment will be better understood for both its triumphs and downfalls.

Educational research in a global economy of knowledge production : what troubles a traveling textworker?

The first (and most specific) postcolonial intersection to which this paper refers was constituted initially by an Australian-South African institutional links project (funded by the Australian federal government) and subsequent collaborations and partnerships between Australian and South African academics arising (directly or indirectly) from this project. In this paper I will focus on activities that were intended to enhance research capacity in educational leadership and in environmental education, with particular reference to appropriate methodologies and supervision practices. Other postcolonial intersections to which this paper will refer include those that have been formed as a result of international students from various locations in Africa and Asia studying at Deakin (either on-campus or by distance modes). My purposes in the paper are (i) to examine, through cases and examples, some ways in which difference (with particular reference to race, ethnicity, language and location) might be linked to individual and/or community dispositions to take up (or to reject) specific research methodologies and epistemologies, and (ii) to consider the implications of such differences and dispositions for academic practices directed towards developing 'communities of understanding' at postcolonial intersections.

Having a baby and being in school : researching pregnant and parenting young people and their educational transitions

This paper reports on the 2002 pilot phase (in a provincial city) of a continuing study of pregnant and parenting young people and their movements in and out of school (and other educational) settings. It presents an overview of methodological approaches employed and dilemmas encountered, data collected and readings of that data, and an indication of how issues identified from the pilot study have informed the directions and emphases of an expanded investigation for 2003 and beyond. The paper draws on specific cases to identify how young people negotiate their way in and out of school during this phase of their lives. It offers an insight into how young people see themselves ''becoming somebody'' in and around other identity work they engage in while pregnant and parenting at school. The research provides knowledge about the intersection between the institutional and individual complexities of leaving and staying-on at school, including an account of the academic and social reasons for leaving or returning to school and school responses to student pregnancy and parenting.

Actor network theory goes to school

Actor Network Theory (ANT) is explored as a useful tool in researching the intersection of English teaching and Information Communication Technologies (ICTs), to understand the complex interaction of influences, both human and non-human, that combine to achieve a particular outcome, in this case the uptake of ICTs by English teachers in an Australian school. What this means is that alongside interviewing the teachers, administrators and technical support people, recognition is given to the influence of inanimate objects such as computers, bluestone walls and curriculum documents. This constructs a more complex picture of the change process accounting both for the invisible ideology of teacher beliefs as well as the technical capacity and incapacity of machines, buildings and policies. At the heart of ANT lies the metaphor of the heterogeneous network which is made up of diverse, not simply human, materials. Often these networks become consolidated as single point actors e.g. the English curriculum, the computer laboratory, the library, which are then seen as fixed entities rather than an amalgamation of parts prone to change. ANT allows for the constituent parts to be investigated, and following Bruno Latour's Aramis, (1996) this can be done creatively by literally giving voice to inanimate objects such as computers.

Measuring the walkability of local communities using geographic information systems data

Researchers are working to identify and promote environment and policy initiatives to encourage more active and healthy communities. Measuring environmental attributes through objective means can verify which physical environment factors are most important. We describe how Geographic Information Systems (GIS) may be used to measure objectively, the features of the built environment that may influence walking. We show how four key attributes currently believed to be of most relevance to walking for transport may be used to create a ‘walkability’ index. These are dwelling density (higher-density neighbourhoods support greater retail and service variety, resulting in shorter, walkable distances between facilities; driving and parking are more difficult); street connectivity (higher intersection density provides people with a greater choice of potential routes, easier access to major roads where public transport is available and shorter times to get to destinations); land use mix (the more varied the land use mix and built form, the more conducive it is to walk to various destinations); and net retail area (people who live near multiple and diverse retail opportunities are able to make more frequent and shorter shopping trips by walking and can walk to more local employment opportunities). The potential relationships between each of the objective environmental-attribute measures and walking behaviours is discussed, together with suggestions as to how such measures might be used to guide community infrastructure planning. GIS mapping can assist decision makers in where to focus transportation investments and where to guide future growth. Readily accessible GIS data can be used to guide and support urban planning and infrastructure investment decisions in both the private and public sectors, to increase walking in communities.

Teacher is here to ask for your help : a story of schools, employers and networks

This paper explores the development of the Jobs4Kids (J4K) campaign, a joint initiative of the SGR LLEN Employer Reference Group and the Beacon Foundation. Involving a three-year business plan, the J4K campaign aims to broker young people into employment in local jobs in the region. The campaign is the result of the intersection between an evolving project within the LLEN and the growth of an established program of the Beacon Foundation. The paper will use a Deleuzian lens to explore the ground shifts that have occurred in the process of forming this connection; I am concerned with the intersecting movements of different orders that have created a necessary transitory coordination. Within such a 'rhizome' there are only lines: dimensional lines of segmentarity and stratification and lines of flight as 'the maximum dimension after which the multiplicity undergoes metamorphosis, changes in nature' (Deleuze & Guattari 1987 p.21). My perspective of this metamorphosis is specifically focused on SGR LLEN; I close with a consideration of the possibilities of this change in nature for the continuing work of the LLEN.

"Where myth becomes history" : the politics of mythical time in Heiner Muller's Medea

Heiner Müller in the 1980s produced a sequence of plays featuring Euripides’ heroine Medea using his distinctive, poetic modality of “the theatre of images”. These ostensibly postmodern narratives take the form of disjointed, visual and textual representations that are also fragmentations of historical and mythical times and spaces. Müller’s Medea plays are thus suggestive of the intersection between the discourses of history and myth — and the blending of historical time with ahistorical, supposedly “timeless” mythical narratives. Further, the postmodern possibility of history’s textuality to liquidate it into a type of (modern) mythology seeks expression in the plays’ representation of a converse equation: the moment signaled in the text as that “where myth becomes history”. This paper examines the problematisation of the myth-history dichotomy in Müller’s Medea plays, outlining the ways in which the “timeless” myth of the classical, infanticidal figure of Medea is strategically deployed to politicise evolutionist teleology, Western colonialism and the technologies of war in twentieth century Europe.

Not quite white (enough) : intersecting ethnic and gendered identities in 'Looking for Alibrandi'

The intersections between raced and gendered identity, treating identity-formation as a function of biological, cultural and ideological codifications that cannot be readily disentangled is assessed by an analysis of the novel Looking for Alibrandi. This novel embodies this intersection of identity politics in ways that suggest that rethinking multiculturalism and whiteness also mean rethinking gender.

An Australian version of the neighborhood environment walkability scale : validity evidence

This study examined validity evidence for the Australian version of the Neighborhood Environment Walkability Scale (NEWS-AU). A stratified two-stage cluster sampling design was used to recruit 2,650 adults from Adelaide (Australia). The sample was drawn from residential addresses within eight high-walkable and eight low-walkable suburbs matched for socio-economic status (SES). Neighborhood walkability was measured using Geographic Information Systems data on dwelling density, intersection density, net retail area, and land-use mix. Participants completed the NEWS-AU and reported weekly minutes of walking for transport and recreation (International Physical Activity Questionnaire [IPAQ]). Multilevel confirmatory factor analysis (MCFA) was used to define the individual- and Census Collection District (CCD)-level measurement model of the NEWS-AU. Seven individual-level and five CCD-level factors were identified. These measurement models were somewhat similar to those of the original Neighborhood Environment Walkability Scale (NEWS). Patterns of associations between the NEWS-AU factors/scales and the walking measures provided some validity evidence for the instrument.

Tolling for the luckless, the abandoned and forsaked : therapeutic jurisprudence and international human rights law as applied to prisoners and detainees by forensic psychologists

Objectives. There has been an explosion of interest in therapeutic jurisprudence as both a filter and lens for viewing the extent to which the legal system serves therapeutic or anti-therapeutic consequences. However, little attention has been paid to the impact of therapeutic jurisprudence on questions of international human rights law and the role of forensic psychologists. The paper aims to provide an intersection between human rights, therapeutic jurisprudence, and forensic psychology.

Method. Human rights are based on legal, social, and moral rules. Human rights literature generally considers legal rights but such policy statements do not provide principles to guide forensic psychologists in addressing moral or social rights. Therefore, a framework to guide forensic psychologists is required.

Conclusion. As duty-bearers, forensic psychologists need to address the core values of freedom and well-being in rights holders (in this instance, prisoners and detainees with a mental illness). The paper proposes that human rights principles can add to the normative base of a therapeutic jurisprudence framework, and in-turn, therapeutic jurisprudence can assist forensic psychologists to actively address human rights.

Abjection and midwifery : towards a revision of Julia Kristeva's theory of the maternal

This paper will develop a specific reading of Julia Kristeva’s analysis of the Mother in psychoanalytic contexts and artistic production. I want to suggest a particular connection between the Mother and a second figure closely associated with her: the Midwife. Such a move opens up the possibility for a new understanding of Kristeva’s correlation of the Mother with the psychoanalytic concept of “abjection”. I wish to identify the Midwife as the crucial intersection of a masculine and feminine subjectivity. I will undertake this project via a historical study of Midwifery, which will include an exploration of the Midwife’s relationship to masculine ideologies of medical thought, as well as an account of the problematic rise of the “Man-Midwife”. My strategy will be to extend the submerged historical and material content of Kristeva’s own theories, with particular reference to Powers of Horror: An Essay on Abjection.

Family in transition: parents, children and grandparents in lesbian families give meaning to 'doing family'

Lesbian parents, their children and grandparents ‘do family’ in rich and diverse ways. This article draws on innovative grounded theory research using qualitative, multi-generational family interviews with twenty lesbian- parented families living in Victoria, Australia. The intersection between the public and the private in lesbian family life has been seriously neglected by family researchers, and in particular the perspectives of family members other than the lesbian parents themselves. This article addresses the question of ‘How members of lesbian-parented families define and describe their family’, and the results reported here focus on children’s and grandparents’ views, because they are the voices less well represented in the literature. Children and grandparents straddle both mainstream and marginalized spaces as they negotiate contemporary family life. We examine the interface and tensions between the traditional and the transformative, and the implications of these findings for family therapists are briefly discussed.

Hyphenated Australia : putting intercultural identity on the conceptual map

Interculturality and intercultural identity is a local effect of the global movement and mixing of people, and those of intercultural identities constitute the fastest growing sector of the Australian population. In an age of globalisation and diversification, what does identity mean for those situated in-between governing notions of racial/ethnic formations, and how is intercultural identity experienced? For those informed by (at least) two cultures, what does multiculturalism, ethnicity and 'Australianness' mean, and where are these individuals positioned in relation to these structures? These questions have critical implications for the Australian nation. Within Australian discourses, interculturality and intercultural identity, in particular, has historically been excluded, rendered invisible. This dissertation is, therefore, one of facilitating visibility. Using the hyphens as a conceptual tool, I argue that in this age of accelerating globalisation the hyphens both makes visible and is made visible by interculturality. The hyphens is that grey and fluid site of intersection between structures of identity and is characterised by liminality - contestation, uncertainty, fundamentally ambivalence. Experiences of liminality, however, dissolve in any given time, opening up new terrain for creativity. Some of these emerging and creative forms of identity, as instigated by interculturality, are explored. Based on interviews with 20 daughters (and their mothers) from intercultural unions, this dissertation places intercultural identity on the Australian conceptual map and analyses the unique position occupied by those with an intercultural identity in their relationship with governing discursive formations of race/ethnicity, embodiment, nation and culture. In essence, the dissertation is concerned with examining the ways in which discursive identity structures intersect with subjective experience, and with the ways in which those with an intercultural identity negotiate those structures and their social relations. This examination raises the fundamental question: is the modernist notion of the material realities of individual lives reconcilable with the poststructural notion of identity as always located in discourse. This modernist/postmodernist tension permeates the dissertation.

Ecology of arboreal marsupials in a network of remnant linear habitats

Linear strips of vegetation set within a less-hospitable matrix are common features of landscapes throughout the world. Depending on location, form and function, these linear landscape elements include hedgerows, fencerows, shelterbelts, roadside or streamside strips and wildlife corridors. In many anthropogenically-modified landscapes, linear strips are important components for conservation because they provide a large proportion of the remaining wooded or shrubby habitat for fauna. They may also function to provide connectivity across the landscape. In some districts, the linear strips form an interconnected network of habitat. The spatial configuration of remnant habitat (size, shape and arrangement) may influence habitat suitability, and hence survival, of many species of plant and animal in modified landscapes. Near Euroa in south-eastern Australia, the clearing and fragmentation of temperate woodlands for agriculture has been extensive and, at present, less than 5% tree cover remains, most of which (83%) occurs as linear strips along roads and streams. The remainder of the woodland occurs as relatively small patches and single isolated trees scattered across the landscape. As an assemblage, arboreal marsupials are woodland dependent and vary in their sensitivity to habitat loss and fragmentation. This thesis focusses on determining the conservation status of arboreal marsupials in the linear network and understanding how they utilise the landscape mosaic. Specifically, the topics examined in this thesis are: (1) the composition of the arboreal marsupial assemblage in linear and non-linear woodland remnants; (2) the status and habitat preferences of species of arboreal marsupial within linear remnants; and (3) the ecology of a population of the Squirrel Glider Petaurus norfolcensis in the linear network, focusing on population dynamics, spatial organisation, and use of den trees. The arboreal marsupial fauna in the linear network was diverse, and comprised seven out of eight species known to occur in the district. The species detected within the strips were P. norfolcensis, the Sugar Glider Petaurus breviceps, Common Brushtail Possum Trichosums vulpecula, Common Ringtail Possum Pseudocheirus peregrinus, Brush-tailed Phascogale Phascogale tapoatafa, Koala Phascolarctos cinereus and Yellow-footed Antechinus Antechinus flavipes. The species not detected was the Feathertail Glider Acrabates pygmaeus. Survey sites in linear remnants (strips of woodland along roads and streams) supported a similar richness and density of arboreal mammals to sites in non-linear remnants (large patches or continuous tracts of woodland nearby). Furthermore, the combined abundance of all species of arboreal marsupials was significantly greater in sites in the linear remnants than in the non-linear remnants. This initial phase of the study provided no evidence that linear woodland remnants support a degraded or impoverished arboreal marsupial fauna in comparison with the nonlinear remnants surveyed. Intensive trapping of arboreal marsupials within a 15 km linear network between February 1997 and June 1998 showed that all species of arboreal marsupial (except A. pygmaeus) were present within the linear strips. Further analyses related trap-based abundance estimates to measures of habitat quality and landscape structure. Width of the linear habitat was significantly positively correlated with the combined abundance of all arboreal marsupials, as well as with the abundance of P. norfolcensis and T. vulpecula. The abundance of T. vulpecula was also significantly positively correlated with variation in overstorey species composition, Acacia density and the number of hollow-bearing trees. The abundance of P. norfolcensis was positively correlated with Acacia density and canopy width, and negatively correlated with distance to the nearest intersection with another linear remnant. No significant variables were identified to explain the abundance of P. tapoatafa, and there were insufficient captures of the remaining species to investigate habitat preferences. Petaurus norfolcensis were resident within the linear network and their density (0.95 -1.54 ha-1) was equal to the maximum densities recorded for this species in continuous forest elsewhere in south-eastern Australia. Rates of reproduction were also similar to those in continuous forest, with births occurring between May and December, a mean natality rate of 1.9, and a mean litter size of 1.7. Sex ratios never differed significantly from parity. Overall, the population dynamics of P. norfolcensis were comparable with published results for the species in contiguous forest, clearly suggesting that the linear remnants currently support a self-sustaining, viable population. Fifty-one P. norfolcensis were fitted with radio transmitters and tracked intermittently between December 1997 and November 1998. Home ranges were small (1.3 - 2.8 ha), narrow (20 - 40 m) and elongated (322 - 839 m). Home ranges were mostly confined to the linear remnants, although 80% of gliders also utilised small clumps of adjacent woodland within farm paddocks for foraging or denning. Home range size was significantly larger at intersections between two or more linear remnants than within straight sections of linear remnants. Intersections appeared to be important sites for social interaction because the overlap of home ranges of members of adjacent social groups was significantly greater at intersections than straight sections. Intersections provided the only opportunity for members of three or more social groups to interact, while still maintaining their territories. The 51 gliders were radiotracked to 143 different hollow-bearing trees on 2081 occasions. On average, gliders used 5.3 den trees during the study (range 1-15), and changed den trees every 4.9 days. The number of den trees used by each glider is likely to be conservative because the cumulative number of den trees continued to increase over the full duration of the study. When gliders shifted between den trees, the mean distance between consecutive den sites was 247 m. Den trees were located throughout a glider's home range, thereby reducing the need to return to a central den site and potentially minimising energy expenditure. Dens were usually located in large trees (mean diameter 88.5 cm) and were selected significantly more often than expected based on their occurrence within the landscape. The overall conclusion of this thesis is that the linear network I studied provides high quality habitat for resident populations of arboreal marsupials. Important factors influencing the suitability of the linear remnants appear to be the high level of network connectivity, the location on soils of high nutrient status, the high density of large trees and an acacia understorey. In highly fragmented landscapes, linear habitats as part of the remaining woodland mosaic have the potential to be an integral component in the conservation of woodland-dependent fauna. The habitat value of linear strips of vegetation should not be underestimated.
