Solar performance-driven urban development: the case of western Sydney, Australia

ABSTRACT Urban densification, a response to population growth, poses adverse impacts on built environments. Limited access to sunlight is one of these consequences. Solar radiation and daylight affect urban canyons in different ways, including thermal comfort and illuminance levels. A balance between summer and solar heat gain can alleviate solar thermal considerations. This becomes even more important in an urban context like Western Sydney with an air temperature of around 6 to 10 degrees hotter than Inner Sydney (during extreme heat events). Additionally, Western Sydney is predicted to absorb two-thirds of the population growth of the Sydney region. Nevertheless, the urban development trend in this region doesn’t seem to meet the requirements of an environmentally sustainable scheme covering solar geometry-based design principles. Therefore, this study aims to develop a general urban model based on the spatial analysis of the western Sydney suburbs and propose a novel integrated methodology to provide the optimal solar-based urban design solution. This process uses an evolutionary algorithm as a computational tool to optimize solar radiation and daylight levels in extreme weather conditions. Results offer the optimum value for a wide range of design parameters regarding solar geometry.

Urban density, household overcrowding and the spread of COVID-19 in Australian cities

The UN-Habitat World Cities Report 2020 highlighted that overcrowded housing, not urban density, is the major contributing factor to the spread of COVID-19. The relatively successful ability of densely populated cities such as Seoul, Singapore, Tokyo and New York City to manage virus spread supports this. We hypothesise that, given the complexity of the interaction between people and place, the relative contribution of density and crowding to the spread of infectious diseases may be contingent on local factors. To directly compare the role of urban density and household overcrowding, we examine each in relation to COVID-19 incidence in the three largest cities in Australia, Sydney, Melbourne and Brisbane, as the pandemic unfolded from July 2021 to January 2022. Using ecological models adjusted for spatial autocorrelation and area-level measures of age and socio-economic factors, we assess the association between population density, overcrowding in homes, and COVID-19 infections in local neighbourhoods. Challenging prevailing assumptions, we find evidence for an effect of both density and overcrowding on COVID-19 infections depending on the city and area within cities; that is, depending on the local context. For example, in the southwestern suburbs of Sydney, the case rate decreases by between 0.4 and 6.4 with every one-unit increase in gross density however the case rate increases by between 0.01 and 9.6 with every one-unit increase in total overcrowding. These findings have important implications for developing pandemic response strategies: public health measures that target either density (e.g., lockdowns and restricted range of travel) or overcrowding (e.g., restricting number of people relative to dwelling, mask-wearing indoors, vaccination prioritisation) must be cognisant of the geographically local contexts in which they are implemented.

Analyzing The Identity And Dreams of The Displaced In Aravind Adiga’s Amnesty

The Indian writer Aravind Adiga, in his novel Amnesty, narrates the dreams and identity crises faced by migrants and displaced people through the life of migrant Danny. This work tells the story of a Sri Lankan who is forced by circumstances to become an “ Illegal alien” after being a drop out from his “ripoff” college in Australia. Danny settles on cleaning and maintaining the sanitation in apartments in the suburbs of Sydney. The twist in the plot and the question of the immigrant’s dreams being a success arise when Radha Thomas, a client of Danny, is murdered. Danny is aware of the murderer, who is another of his clients, Dr. Prakash. Danny is overwhelmed and ponders the dilemma of whether to inform the police and risk being deported or to remain silent. This ambiguous state of the migrant is analyzed in this paper.

Letting the plants speak: Law, landscape and conservation.

The Botany Wetlands are the contemporary remnant of a formerly extensive coastal freshwater wetland in the inner-urban suburbs of Sydney (Australia). This site supports a range of ecosystem services, including human physical and mental health benefits, filtration of stormwater runoff from a highly urban and industrial catchment, and accommodation space for floodwater. The wetlands also provide habitat to migratory water birds and act as a connective habitat corridor and refuge for native flora and fauna including endangered ecological communities recognised in state and national legislation. Current management strategies and 'on the ground' practices are informed by a hierarchy of laws and management plans that act to create and reinforce a specific narrative in the material landscape. Here we consider the ecological history of the wetlands, derived from paleoecological data, in the context of this complex network of governance entanglements. We argue that the system bears little resemblance to its long-term character and has been made and continually re-made by a portmanteau of inflexible regulatory structures. We suggest that maintaining ecosystem services in such a complex, hybridized sociolegal-biophysical system requires a critical view of both the power relations and physical processes that shape it.

Redeveloping the compact city: the challenges of strata collective sales

PurposeHigh-density development requires large land parcels, but fragmented land ownership can impede redevelopment. While earlier compact city development in Sydney occurred on large-scale brownfield sites, redeveloping and re-amalgamating older strata-titled properties is now integral to further densification. The purpose of this study is to examine collective sales activity in one Sydney suburb where multiple strata-titled redevelopments and re-amalgamations have been attempted. The authors explore how owners navigate the process of selling collectively, focusing on their experience of legislation introduced to facilitate this process, the Strata Schemes Development Act 2015 [New South Wales (NSW)].Design/methodology/approachBy reviewing sales listings, development applications and media coverage, and interviewing owners, lawyers and estate agents, the authors map out collective sale activity in a case study area in Sydney’s northwest.FindingsStrata collective sales are slow and difficult to complete, even when planning and market drivers align. Owners find the Strata Scheme Development Act 2015 (NSW) difficult to navigate and it has not prevented strategic blocking attempts by competing developers. The long timelines required to organise collective sales can result in failure if the market shifts in the interim. Nonetheless, owners remain interested in selling collectively.Originality/valueThis case study is important for understanding the barriers to redevelopment to achieve a more compact city. It highlights lessons for other jurisdictions considering similar legislative changes. It also suggests that legislative change alone is insufficient to resolve the planning challenges created by hyper-fragmentation of land through strata-title development.

Bondi to Byron: divergent pathways in NSW’s Metropolitan and regional rental markets during the COVID-19 pandemic

ABSTRACT In this paper, we look to compare the differential responses of metropolitan and regional rental markets in the first 12 months post-pandemic in New South Wales, Australia’s most populous state. We employ descriptive statistics to analyse broad trends in both rental prices and transfers in and out of long-term rental supply through the short-term letting and property buyer markets. Moreover, we examine how these dynamics have played out at the local level using the contrasting case studies of Bondi in the eastern suburbs of Sydney and Byron Bay in the northern rivers of NSW. The results demonstrate that there have been distinctly separate responses to the pandemic across different geographical profiles, displaying cohort-level behaviours ranging from rental declines in inner-city areas to significant increases in high-price regional areas. Furthermore, a comparison of metro and regional markets highlights a strong and symmetrical association between short-term lettings activity and changes in long-term rental prices over the initial COVID-19 period. Finally, analysis of investor activity exhibits a highly reactive and geographically differentiated response to changes in rental yields. Ultimately, the findings of this study further the understanding of the contrasting responses at the local scale to the COVID-19 pandemic, the complex interplay between long- and short-term rental markets and help shed light on necessary future policy directions for NSW’s, and Australia’s, housing market.

Spatial Contexts of Language Shift and Heritage Language Retention within a Highly Diverse Population: Sydney, Australia

AbstractIn immigrant countries like America, Canada and Australia, heritage language retention and language shift (to the language of the receiving society) have long been associated with classical spatial theory, of initial segregation into inner city ethnic enclaves and subsequent intra‐urban migration into majority ‘white’ or ‘mainstream’ residential suburbia, respectively. First through third generation spatial dynamics of shift and retention in Sydney are analysed for the ten largest post‐1945 labour workforce immigrant streams from Europe and the ten post‐1960s mainly skilled immigrant streams from the Middle East and Asia. Quartile and diversity analyses show that the association of intergenerational heritage language retention with spatial concentration and language shift with spatial dispersion has been superceded by a new set of spatial dynamics. Instead, patterns of retention and shift are responding to high levels of population diversity and minority majority suburbs where culturally hegemonic mainstream and minority cultural groups are intermixed across 80 per cent of Sydney's suburbs.

The diversity of providers’ and consumers’ views of virtual versus inpatient care provision: a qualitative study

BackgroundA broad-based international shift to virtual care models over recent years has accelerated following COVID-19. Although there are increasing numbers of studies and reviews, less is known about clinicians’ and consumers’ perspectives concerning virtual modes in contrast to inpatient modes of delivery.MethodsWe conducted a mixed-methods study in late 2021 examining consumers’ and providers’ expectations of and perspectives on virtual care in the context of a new facility planned for the north-western suburbs of Sydney, Australia. Data were collected via a series of workshops, and a demographic survey. Recorded qualitative text data were analysed thematically, and surveys were analysed using SPSS v22.ResultsAcross 12 workshops, 33 consumers and 49 providers from varied backgrounds, ethnicities, language groups, age ranges and professions participated. Four advantages, strengths or benefits of virtual care reported were: patient factors and wellbeing, accessibility, better care and health outcomes, and additional health system benefits, while four disadvantages, weaknesses or risks of virtual care were: patient factors and wellbeing, accessibility, resources and infrastructure, and quality and safety of care.ConclusionsVirtual care was widely supported but the model is not suitable for all patients. Health and digital literacy and appropriate patient selection were key success criteria, as was patient choice. Key concerns included technology failures or limitations and that virtual models may be no more efficient than inpatient care models. Considering consumer and provider views and expectations prior to introducing virtual models of care may facilitate greater acceptance and uptake.

Developing profession ready teacher education graduates through school-university partnerships: an Australian study

ABSTRACT The engagement of both school and university has played a significant role in initial teacher education. The focus of this paper is the growth of an alternative style of school-university partnership from a single school to a Hub of 19 school-university partnership, in the inner-west suburbs of Sydney, Australia. Four school and university mentors who have participated over a seven-year period have completed surveys on their engagement. Using a Community of Practice (CoP) theoretical framework to underpin model development, it is possible to showcase the growth of the partnerships as important in informing discussion relating to the implementation of integrated school-university partnerships and practice.

Comparison of nutrition profiling models for food marketing regulation.

Regulation on food marketing to children is a recommended response to childhood obesity rates. Policy requires country-relevant criteria to determine which foods are eligible to be advertised. This study aims to compare six nutrition profiling models for use in food marketing regulation in Australia. Advertisements on the outside of buses in five suburban Sydney transport hubs were photographed. Food and beverages advertised were analysed using the Health Star Rating; three models developed for food marketing regulation: the Australian Health Council guide and two World Health Organization models; the NOVA system; and the Nutrient Profiling Scoring Criterion used in Australian advertising industry codes. The proportion and types of products advertised on the buses that would be permitted by each of the six models were then analysed. A total of 603 advertisements were identified. Of those, over a quarter of the advertisements were for foods and beverages (n = 157, 26%) and 2.3% (n = 14) for alcohol. Among the food and non-alcoholic beverage advertisements, 84% were for unhealthy foods according to the Health Council guide. The Health Council guide would permit 31% unique foods to be advertised. The NOVA system would permit the least proportion of foods to be advertised (16%), while the Health Star Rating (40%), and Nutrient Profiling Scoring Criterion (38%) would permit the most. The Australian Health Council guide is the recommended model for food marketing regulation because it aligns with dietary guidelines by excluding discretionary foods from advertising. Australian governments can use the Health Council guide to develop policy in the National Obesity Strategy to protect children from marketing of unhealthy food.

Indigenous university pathways, WIL and the strengthening of aspirations: Robbie’s journey as a learner

ABSTRACT The underrepresentation of boys from Aboriginal and Torres Strait Islander peoples in Australian universities continues despite recent gains in widening participation. This article presents a case study documenting the transition of one Indigenous student, Robbie, from an underprivileged school located in the Western suburbs of Sydney to an urban Australian university. We focus first on his experience at university before considering how an opportunity with Work-Integrated Learning (WIL) influenced his confidence and motivation. Central to the analysis is the continual and contentious nature of Robbie’s identity work concerning the opportunities he encounters. In exploring Robbie’s journey as a learner, his experiences compel us to reflect on how facets of his learner identity change in relation to opportunities and what this may mean for how equity programmes provide support for vulnerable learners – specifically how we can improve outcomes for young men from underrepresented backgrounds.

The Spider Silk Standardization Initiative (S3I): A powerful tool to harness biological variability and to systematize the characterization of major ampullate silk fibers spun by spiders from suburban Sydney, Australia

The true stress-true strain curves of 11 Australian spider species from the Entelegynae lineage were tensile tested and classified based on the values of the alignment parameter, α*, in the framework of the Spider Silk Standardization Initiative (S3I). The application of the S3I methodology allowed the determination of the alignment parameter in all cases, and were found to range between α* = 0.03 and α* = 0.65. These data, in combination with previous results on other species included in the Initiative, were exploited to illustrate the potential of this approach by testing two simple hypotheses on the distribution of the alignment parameter throughout the lineage: (1) whether a uniform distribution may be compatible with the values obtained from the studied species, and (2) whether any trend may be established between the distribution of the α* parameter and phylogeny. In this regard, the lowest values of the α* parameter are found in some representatives of the Araneidae group, and larger values seem to be found as the evolutionary distance from this group increases. However, a significant number of outliers to this apparent general trend in terms of the values of the α* parameter are described.

Building young men: a dynamic group mentoring program at the intersection of group work, mentoring, adolescence, and sport

ABSTRACT The Building Young Men group mentoring program is a new and innovative youth intervention program located in the outer suburbs of Sydney, Australia. Funded and facilitated by a professional sporting organization, the program incorporates the practices of group work, youth work, and mentoring to support adolescent males in exploring safe and healthy transitions into adulthood. The authors have offered the term “Dynamic Group Mentoring,” to describe the experience at the intersection of the interventions of group work, youth work, and mentoring as practiced in the Building Young Men program. This model of group mentoring offers significant positive outcomes for adolescent male participants, particularly in supporting the development of confidence, trust, agency, and social capital in their lives.

Gambling, fast food and alcohol sponsorship in elite sport – perspectives from Australian sporting fans

BackgroundPublic health bodies in Australia remain concerned about marketing of unhealthy commodities; namely unhealthy food, alcohol and gambling products. Children are particularly susceptible to the influence of unhealthy commodity marketing. This study explored adults’ perceptions of unhealthy commodities sponsorship in elite sport and policies to restrict them.MethodsFour focus groups of 7–8 frequent sport spectators were recruited, including parents and non-parents, and located in inner and outer suburbs of Sydney, Australia. Results were analysed thematically.ResultsParticipants identified the contradictions of healthy messages of sport and unhealthy commodities, while highlighting the commercial value of sport sponsorship to sporting clubs. There is concern around children’s exposure to effective and integrated marketing techniques when viewing sport, which encouraged unhealthy habits. Support for restricting sponsorship related to perceived product harm, with gambling viewed as having the greatest health impact. Participants were supportive of policies that reduced exposure of unhealthy commodities to children, but were concerned about the financial risk to sporting clubs. Governments and sports associations were identified as holding responsibility for enacting changes.ConclusionA number of options were identified for advocates to gain public and political traction to reduce unhealthy commodity sponsorship. There is potential for shifts away from unhealthy sponsorship by both governments and sports associations.

Ramadan: devotion, compassion, and purification in Sydney

While Ramadan in Western societies has been studied extensively in relation to health issues, no research to date has explored its representation through social scientific lenses. This article uses the Greater Western Sydney region in New South Wales, Australia, as a case study. This agglomeration of suburbs from the outer western suburbs of Sydney to the Blue Mountains has the highest proportion of Muslims in the country. To understand the representation of Islam in this region, this paper first analyses the articles in its major and local newspapers to then contrast them to the way the Ramadan festival is represented by mosques on their websites. This research discovers that Ramadan in Sydney newspapers tends to be reported in a secular fashion with a stronger focus on its public and economic activities. The focus of a large proportion of these articles on the way it attracts business demonstrates that it is a well-accepted event in Australia. In contrast, the pictures provided in Muslim sites in Sydney are more religious than the newspaper depiction and show a contrast with regard to ethnicity and gender. While the newspaper pictures are from the public sphere and tend to be multicultural across various Muslim ethnicities and do not show gender segregation, the online pictures from Muslim organisation show a strong gender segregation and represent the local ethic community they serve. While the representations in the public sphere are neo-liberal post-secularism and multiculturalism, those from these organisations are curating religiously important rather than business orientated moments in their community.

Suburban vogue and other queer survival strategies

ABSTRACT Vogue conjures many things: honed Black and Brown queer and trans bodies, queer space, and communal resistance to hostile worlds. It is rarely something associated with the suburbs, US or elsewhere. This article investigates how the international expansion of vogue leads to the raced and geographic specificity of suburban Sydney. It does this through an analysis of Slay Your Oppressor(s) (2016), a hybridized vogue-martial arts performance by Bhenji Ra, Kilia Tipa, and Davina Chor held in an outer-suburban shopping strip. My account of Slay and the queer cultural histories and formations it brings to the fore is framed by the racialization of Sydney’s suburbs that condition the dominant urban narrative of escape from suburban exclusion. I argue that Slay mines the realities of violence against non-normative Brown bodies while complicating notions of inclusion. The instrumentalization of vogue as a form of self-defence highlights the multiple dimensions of queer survival strategies, many of which are lost in the longstanding theoretical standoff between accounts of suburban normativity and urban antinormativity. Relays between international queer capitals such as New York, iconic dance and cultural forms such as vogue, and maligned spaces thought to be devoid of queerness such as suburban Sydney resolve through local understandings of queerness and race. This article argues that suburban vogue displaces certainties around gender, sexuality, family, resistance, and the models of inclusion/exclusion they traffic in.

Detection of Water Leaks in Suburban Distribution Mains with Lift and Shift Vibro-Acoustic Sensors

Leaks in Water Distribution Networks (WDNs) account for a large proportion of Non-Revenue Water (NRW) for utilities worldwide. Typically, a leak is only confirmed once water surfaces, allowing the leak to be traced; however, a high percentage of leaks may never surface, incurring large water losses and costs for utilities. Active Leak Detection (ALD) methods can be used to detect hidden leaks; however, the success of such methods is highly dependent on the available detection instrumentation and the experience of the operator. To aid in the detection of both hidden and surfacing leaks, deployment of vibro-acoustic sensors is being increasingly explored by water utilities for temporary structural health monitoring. In this paper, data were collected and curated from a range of temporary Lift and Shift (L&S) vibro-acoustic sensor deployments across suburban Sydney. Time-frequency and frequency-domain features were generated to assess the performance and suitability of two state-of-the-art binary classification models for water leak detection. The results drawn from the extensive field data sets are shown to provide reliable leak detection outcomes, with accuracies of at least 97% and low false positive rates. Through the use of such a reliable leak detection system, utilities can streamline their leak detection and repair processes, effectively mitigating NRW and reducing customer disruptions.

Comparing the Impact of Road Networks on COVID-19 Severity between Delta and Omicron Variants: A Study Based on Greater Sydney (Australia) Suburbs.

The Omicron and Delta variants of COVID-19 have recently become the most dominant virus strains worldwide. A recent study on the Delta variant found that a suburban road network provides a reliable proxy for human mobility to explore COVID-19 severity. This study first examines the impact of road networks on COVID-19 severity for the Omicron variant using the infection and road connections data from Greater Sydney, Australia. We then compare the findings of this study with a recent study that used the infection data of the Delta variant for the same region. In analysing the road network, we used four centrality measures (degree, closeness, betweenness and eigenvector) and the coreness measure. We developed two multiple linear regression models for Delta and Omicron variants using the same set of independent and dependent variables. Only eigenvector is a statistically significant predictor for COVID-19 severity for the Omicron variant. On the other hand, both degree and eigenvector are statistically significant predictors for the Delta variant, as found in a recent study considered for comparison. We further found a statistical difference (p < 0.05) between the R-squared values for these two multiple linear regression models. Our findings point to an important difference in the transmission nature of Delta and Omicron variants, which could provide practical insights into understanding their infectious nature and developing appropriate control strategies accordingly.
