“People’s law” and restorative justice: the success of circle sentencing in New South Wales

Informal sentencing procedures in remote Indigenous communities of Australia have been occurring for some time, but it was in the late 1990s that formalization of the practice began in urban areas with the advent of Indigenous sentencing and circle courts. These circle courts emerged primarily to address the over-representation and incarceration of Indigenous people in the criminal justice system. The first Indigenous urban court was assembled in Port Adelaide, South Australia in June 1999 and was named the Nunga Court. Courts emerging since in other states are based on the Nunga Court model, although they have been adapted to suit local conditions. The practice of circle sentencing was introduced in New South Wales (NSW) in Nowra in February 2002.

2Loud? Monitoring traffic noise with mobile phones

The World Health Organization has recently focused attention on guidelines for night noise in urban areas, based on significant medical evidence of the adverse impacts of exposure to excessive traffic noise on health, especially caused by sleep disturbance. This includes serious illnesses, such as hypertension, arteriosclerosis and myocardial infarction. 2Loud? is a research project with the aim of developing and testing a mobile phone application to allow a community to monitor traffic noise in their environment, with focus on the night period and indoor measurement. Individuals, using mobile phones, provide data on characteristics of their dwellings and systematically record the level of noise inside their homes overnight. The records from multiple individuals are sent to a server, integrated into indicators and shared through mapping. The 2Loud? application is not designed to replace existing scientific measurements, but to add information which is currently not available. Noise measurements to assist the planning and management of traffic noise are normally carried out by designated technicians, using sophisticated equipment, and following specific guidelines for outdoors locations. This process provides very accurate records, however, for being a time consuming and expensive system, it results in a limited number of locations being surveyed and long time between updates. Moreover, scientific noise measurements do not survey inside dwellings. In this paper we present and discuss the participatory process proposed, and currently under implementation and test, to characterize the levels of exposure to traffic noise of residents living in the vicinity of highways in the City of Boroondara (Victoria, Australia) using the 2Loud? application.

Conservation gone to the dogs : when canids rule the beach in small coastal reserves

On most developed coastlines, dunes backing ocean beaches constitute an urbanised landscape mosaic containing remnant pockets of small conservation areas. Urbanised beaches are also prime sites for domestic dogs, known to be environmentally harmful in many other settings. It is unknown, however, whether small, protected parcels of dune are adequate for biological conservation and whether dogs compromise their functional conservation objectives. Here we examine, for two small (2 km ocean boundary) reserves in Eastern Australia abutting an urban area, whether such small reserves can continue to function as effective conservation instruments on ocean beaches, using scavenger community composition and efficiency to assess ecosystem function. Two non-native species of canids—domestic dogs (Canis lupus familiaris) and red foxes (Vulpes vulpes)—were ubiquitous and numerous inside conservation areas, to the point of having become the most abundant vertebrate scavengers at the beach-dune interface, outcompeting native scavengers for wave-cast carrion. Dogs and foxes have effectively supplanted raptors, normally abundant on non-urban beaches in the region, and other avian scavengers, as the principal consumers of animal carcasses both inside the declared reserves and at the urban beach. Whilst the ecological threats posed by foxes are widely and intensively addressed in Australia in the form of fox-control programs, dog controls are less common and stringent. Our data emphasize, however, that managing domestic dogs may be required to the same extent in order to maintain key forms and functions in coastal reserves situated close to urban areas.

Migration-related influences on obesity among sub-Saharan African migrant adolescents in Melbourne, Australia

Aim: The aim of the present study was to examine migration- and socioeconomic-related influences on obesity among African migrant adolescents in Melbourne, Australia. Methods: Anthropometric data were collected from 99 parents and 100 adolescent offspring who also completed questionnaires eliciting demographic, socioeconomic and migration data. Multiple linear regressions were used to assess the relationship between migration- and socioeconomic-related factors and adolescent body mass index (BMI). Results: Only gender and parental BMI were associated with adolescent BMI after adjusting for adolescent age, adolescent gender, religion, parental BMI, parental education level and annual income. Boys (β=-1.45; P < 0.05) had lower BMI than girls. Parental and adolescent BMI were positively associated (β = 0.11; P < 0.05). In examining migration-related factors and adolescent BMI, after adjusting for gender and parental BMI, parental acculturation patterns and pre-migration life environment were associated with adolescent BMI, explaining, respectively, 6.5 and 4.0% of the variance in BMI. An integrated parental acculturation pattern was negatively associated with adolescent BMI (β=-0.17; P < 0.05) while adolescents whose parents came from rural areas had a higher BMI (β = 1.48; P < 0.05) than those whose parents came from urban areas. Adolescent acculturation patterns and length of stay in Australia were non-significantly associated with their BMI. Conclusions: Gender, pre-migration life environment and parental acculturation patterns seem to influence the prevalence of overweight and obesity among African migrant adolescents. Culturally competent obesity prevention programmes targeted towards African adolescents should consider these aspects in their design and delivery; however, further research is required to determine their relative contributions to African adolescent obesity in Australia.

Rural realities: digital communication challenges for rural Australian local governments

Purpose – This article explores challenges for rural Australian local governments during the transition to high-speed broadband infrastructure. Despite the National Broadband Network’s promised ubiquitous connectivity, significant access discrepancies remain between rural and urban areas.Methodology – Empirical findings are drawn from a full-day workshop on digital connectivity, which included participants from seven rural local governments in New South Wales, Australia. Thematic analysis of the workshop transcript was undertaken in order to extrapolate recurring nuances of rural digital exclusion. Findings – Rural communities face inequitable prospects for digital inclusion, and authorities confront dual issues of accommodating connected and unconnected citizens. Many areas have no or poor broadband access, and different digital engagement expectations are held by citizens and local governments. Citizens seek interactive opportunities, but rural authorities often lack the necessary resources to offer advanced participatory practices. Research limitations/implications – While this research draws from a small sample of government officials, their insights are nonetheless heuristically valuable in identifying connectivity issues faced in rural Australia. These issues can guide further research into other regions as well as civic experiences of digital inclusion. Practical/social implications – There is a need to reconceive Australia’s current policy approach to broadband. Greater rural digital inclusion may be achieved by focusing on connectivity as a public interest goal, targeting infrastructure developments to suit local contexts, and implementing participatory digital government practices. Originality/value – The actions suggested would help ensure equity of digital inclusion across Australian municipal areas. Without such changes, there is a risk of rural citizens facing further marginalisation through digital exclusion.

Does the presence and mix of destinations influence walking and physical activity?

Background: Local destinations have previously been shown to be associated with higher levels of both physical activity and walking, but little is known about how specific destinations are related to activity. This study examined associations between types and mix of destinations and both walking frequency and physical activity. Method: The sample consisted of 2349 residents of 50 urban areas in metropolitan Melbourne, Australia. Using geographic information systems, seven types of destinations were examined within three network buffers (400 meters (m), 800 m and 1200 m) of respondents' homes. Multilevel logistic regression was used to estimate effects of each destination type separately, as well as destination mix (variety) on: 1) likelihood of walking for at least 10 min ≥ 4/week; 2) likelihood of being sufficiently physically active. All models were adjusted for potential confounders. Results: All destination types were positively associated with walking frequency, and physical activity sufficiency at 1200 m. For the 800 m buffer: all destinations except transport stops and sports facilities were significantly associated with physical activity, while all except sports facilities were associated with walking frequency; at 400 m, café/takeaway food stores and transport stops were associated with walking frequency and physical activity sufficiency, and sports facilities were also associated with walking frequency. Strongest associations for both outcomes were observed for community resources and small food stores at both 800 m and 1200 m. For all buffer distances: greater mix was associated with greater walking frequency. Inclusion of walking in physical activity models led to attenuation of associations. Conclusions: The results of this analysis indicate that there is an association between destinations and both walking frequency and physical activity sufficiency, and that this relationship varies by destination type. It is also clear that greater mix of destinations positively predicts walking frequency and physical activity sufficiency.

The use of kernel density estimation to examine associations between neighborhood destination intensity and walking and physical activity

BACKGROUND: Local destinations have previously been shown to be associated with higher levels of both physical activity and walking, but little is known about how the distribution of destinations is related to activity. Kernel density estimation is a spatial analysis technique that accounts for the location of features relative to each other. Using kernel density estimation, this study sought to investigate whether individuals who live near destinations (shops and service facilities) that are more intensely distributed rather than dispersed: 1) have higher odds of being sufficiently active; 2) engage in more frequent walking for transport and recreation. METHODS: The sample consisted of 2349 residents of 50 urban areas in metropolitan Melbourne, Australia. Destinations within these areas were geocoded and kernel density estimates of destination intensity were created using kernels of 400m (meters), 800m and 1200m. Using multilevel logistic regression, the association between destination intensity (classified in quintiles Q1(least)-Q5(most)) and likelihood of: 1) being sufficiently active (compared to insufficiently active); 2) walking≥4/week (at least 4 times per week, compared to walking less), was estimated in models that were adjusted for potential confounders. RESULTS: For all kernel distances, there was a significantly greater likelihood of walking≥4/week, among respondents living in areas of greatest destinations intensity compared to areas with least destination intensity: 400m (Q4 OR 1.41 95%CI 1.02-1.96; Q5 OR 1.49 95%CI 1.06-2.09), 800m (Q4 OR 1.55, 95%CI 1.09-2.21; Q5, OR 1.71, 95%CI 1.18-2.48) and 1200m (Q4, OR 1.7, 95%CI 1.18-2.45; Q5, OR 1.86 95%CI 1.28-2.71). There was also evidence of associations between destination intensity and sufficient physical activity, however these associations were markedly attenuated when walking was included in the models. CONCLUSIONS: This study, conducted within urban Melbourne, found that those who lived in areas of greater destination intensity walked more frequently, and showed higher odds of being sufficiently physically active-an effect that was largely explained by levels of walking. The results suggest that increasing the intensity of destinations in areas where they are more dispersed; and or planning neighborhoods with greater destination intensity, may increase residents' likelihood of being sufficiently active for health.

Viable approaches for increasing the efficiency of buiding integrated photovoltaic systems

Nowadays, there is growing interest towards the area of building integrated photovoltaic (BIPV) systems and PV microgrids (MGs) in the field of power generation and distribution systems. This is mainly due to the higher adaptability and compatibility of these systems with preplanned sustainable development strategies in the most urban areas. The quiet operating process and movement free characteristic of photovoltaic systems brought them to the roof tops of the buildings in urban and rural areas and made them the most demanded means of renewable energy systems. This study highlights the problems affecting the performance and efficiency of BIPV systems and presents miscellaneous solutions and recommendations to solve these problems.

Limited functional redundancy in vertebrate scavenger guilds fails to compensate for the loss of raptors from urbanized sandy beaches

Aim: Globally, urbanization is one of the most widespread, intense and ecologically destructive forms of landscape transformation, and it is often concentrated in coastal areas. Theoretically, species losses attributable to urbanization are predicted not to alter overall ecosystem function if functional redundancy (i.e. replacement of function by alternative species) compensates for such losses. Here, we test this expectation by measuring how coastal urbanization affects scavenger guilds on sandy beaches and whether changes in guild composition result either in an overall loss of scavenging efficiency, or in functional compensation under alternative guild structures, maintaining net ecosystem functioning. Location: Fourteen beaches along the east coast of Australia with variable levels of urbanization. Methods: Scavenging communities and rates of carrion removal were determined using motion-triggered cameras at the beach-dune interface. Results: A substantial shift in the community structure of vertebrate scavengers was associated with gradients in urbanization. Iconic and functionally important raptors declined precipitously in abundance on urban beaches. Importantly, other vertebrates usually associated with urban settings (e.g. dogs, foxes, corvids) did not functionally replace raptors. In areas where < 15% of the abutting land had been developed into urban areas, carcass removal by scavengers was often complete, but always > 70%. Conversely, on beaches bordering coastal cities with < 40% of natural vegetation remaining, two-thirds of fish carcasses remained uneaten by scavengers. Raptors removed 70-100% of all deployed fish carcasses from beaches with < 8% urban land cover, but this number dropped significantly with greater levels of urbanization and was not compensated by other scavenger species in urban settings. Main conclusions: There is limited functional redundancy in vertebrate scavenger communities of sandy beach ecosystems, which impacts the system's capacity to mitigate the ecological consequences of detrimental landscape transformations.
